Description

A control handle and biopsy system

Technical field

The present invention relates to the technical field of biopsy systems, and in particular, to a control handle and a biopsy system.

Background technique

Biopsy systems are often used for biopsy and partial or complete resection of abnormal breast tissue. The current method of using biopsy systems is to find abnormal tissues under ultrasound guidance, and use the biopsy system to perform biopsy sampling or resection. The working principle of breast tissue biopsy is as follows: the control handle transmits mechanical power to the matching disposable breast rotation puncture needle through gear transmission, and the puncture needle converts the gear transmission into periodic reversing rotational motion and periodic reversing through the mechanical structure. Translational movement, combined to complete the cutting action of abnormal tissue. In addition, the external device provides negative pressure to the matching disposable breast rotation puncture needle through the pipeline connection. The control handle controls the matching puncture needle to open the sampling slot on the needle. Under negative pressure suction, the tissue to be removed is adsorbed on the needle. into the sampling slot on the needle. Subsequently, the control handle controls the puncture needle to close the sampling groove, and the tissue adsorbed in the sampling groove is removed by the cutting edge of the puncture needle to form a complete biopsy sample. The negative pressure provided by the external device is used to transport the resected tissue to the sample collection bin at the tail. The above process of resection and transportation is repeated until all abnormal tissues are cut, and the obtained samples are used for biopsy.

The control handle is a very critical component in the biopsy system. The control handle of the existing biopsy system has the following shortcomings:

(1) The control handle in the existing technology is not waterproof. Medical staff need to clean the control handle before and after surgery. Water will flow into the control handle from the gear box, tail end, and buttons, causing a short circuit or If the circuit breakage is damaged, medical staff can only wipe it with dry cleaning and a small amount of alcohol. It is impossible to ensure that the control handle is cleaned in place. For example, if the buttons are not cleaned in place, there is a risk of contaminating the gloves if the doctor touches the buttons again the next time he uses the product. Failure to clean properly increases the risk of surgical infection.

(2) In the prior art, the connecting cable at the end of the control handle is fixed inside the casing through a cable card. When the connecting cable is pulled hard or the control handle is turned upside down, the gap between the upper and lower casings will be pulled and deformed, and the force will be too strong. The wires will be pulled out, resulting in loose gaps, and the wire harness inside will be pulled and broken, affecting subsequent use.

(3) The function keys on the control handle in the existing technology are single and only have the basic function of cutting, while other functions need to be operated by the host and the trolley. The doctor cannot complete the operation with one hand, and cannot adjust the angle of the knife tube and the inside of the knife tube. Slot length, suction and other functions, when the doctor needs to operate functions other than cutting, he needs to operate back and forth between the control handle end and the host machine and the trolley end, or rely on another operator to assist in the operation, which is inconvenient to operate. In addition, the upper surface of the buttons of the control handle in the prior art is made of hard plastic, which has low surface friction and will slip when used with a doctor's rubber gloves, making continuous contact impossible. The surrounding gaps are large, the buttons will shake, and water can easily leak into the control handle. , causing circuit damage and causing handle failure.

(4) The control handle in the prior art does not have a screen display function or a sound prompt. It is necessary to observe the surgical process and prompts through other supporting equipment, or to transmit information through other medical staff, which is inconvenient to operate.

First embodiment

As shown in Figure 1, this embodiment provides a control handle, including: a handle housing 1, a button structure 2, a control structure 3, a power output structure 4, and a display structure 5;

The button structure 2 is provided on the handle housing 1 and is tightly connected to the handle housing 1. The control structure 3 and the power output structure 4 are provided inside the handle housing 1; The control structure 3 and the button structure 2 are connected by being arranged on the upper PCB board 6 inside the handle housing 1 for receiving operating instructions of the button structure 2; the control structure 3 and the power The output structure 4 is connected to transmit the operating instructions to the power output structure 4; the power output structure 4 is docked with the power input structure on the matching puncture needle structure to transmit power to the puncture needle structure.

As shown in Figure 2, the handle housing 1 includes an upper cover 11, an upper shell 12, a lower shell 13, a locking ring 14 and screws 15; the upper cover 11 is fixed to the upper shell 12. At the front end, the upper cover 11 and the upper shell 12 are glued and fixed; the upper shell 12 is in close contact with the lower shell 13. In this embodiment, the lower shell 13 is a metal piece and the upper shell 12 is plastic. The connection between the upper shell 12 and the lower shell 13 has an outward gap for blocking water from the outside, and the lower shell has an inward landslide for preventing water accumulation, and water flows on the landslide. It will automatically slide down without water accumulation; the locking ring 14 is used to fix the upper shell 12 and the lower shell 13 at the tail end of the control handle to ensure that the upper shell 12 and the lower shell 13 are in close contact and connected. , the screw 15 is used to fix the upper shell 12 and the lower shell 13 at the front end of the control handle, firmly fixing the front ends of the upper shell 12 and the lower shell 13, and at the same time, the screw 15 is in place. There is a gap at the contact point between the upper shell 12 and the lower shell 13. When the contact surface of the puncture needle structure connected to the outside and the control handle interferes, it is ensured that there will be no interference between the upper shell 12 and the lower shell 13. The screw 15 is in too tight contact, causing the outer contact surface to not be in close contact, and the gap is deformed so that the puncture needle structure connected to the outer side is in close contact with the control handle. The present invention does not rely on buckles or other forms to fix the shell 13, so that the upper shell 12 and the lower shell 13 can have good sealing properties and reduce the vibration of the control handle caused by gaps such as buckles.

As shown in Figure 3, the key structure 2 includes a first key structure 21; the first key structure 21 is responsible for performing the cutting action. After pressing the first key structure 21, the command is transmitted to the power output structure 4 through the control structure 3, The transmission of the gearbox in the power output structure 4 is converted into axial linear motion and circumferential motion, and the combination completes the cutting action. The first key structure 21 includes a key cap 211, a button 212, and a tact switch 213. The key cap 211 has a certain friction and will not slip during use, and is tightly connected to the upper cover 11 , ensuring that water will not flow into the interior from the gaps and is waterproof. The button 212 serves as a force transmission member for the key cap 211 and the tact switch 213 and is provided below the key cap 211 and above the tact switch 213 to increase the feel of the first key structure 21. The pressing area of the tact switch 213 is increased to make it more comfortable to use.

As shown in Figure 4, the tact switch 213 is welded to the upper PCB board 6. During the process of pressing the button, the downward force will push downward, making the upper PCB board 6 concave, and the pressing effect will become worse. Therefore, The upper PCB board 6 and the upper cover 11 are fixed by means including fastening screws 214, glue, and buckles.

As shown in Figure 5, the key structure 2 includes a second key structure 22; the second key structure includes a film key 221 and a circuit board 222. The circuit board 222 is fixed to the bottom of the film key 221 by adhesive. , the FPC lines of the circuit board 222 pass through the inner groove of the groove 121 on the upper case 12 in advance, and are then embedded in the groove 121 of the upper case 12 and fixed to the upper case 12 through adhesive. In the groove 121, the adhesive method prevents water from entering and increases the waterproofness. The groove 121 on the surface of the upper case 12 can solve the problem of the membrane button 221 protruding from the surface of the upper case 12 and being unable to be positioned. The FPC line is connected to the upper PCB board 6. The membrane button 221 contains several function keys to expand the functions of the control handle and highly concentrate the functions of the biopsy system on the control handle. At the same time, the second button structure 22 is not only limited to the membrane button described in the present invention, but can also be a silicone button, a plastic button, a touch screen control, and other different control methods.

Further, to give a specific example, the membrane button 211 includes a suction key, a sampling tank adjustment key, a sampling tank adjustment key, a sampling tank clockwise rotation key, a sampling tank counterclockwise rotation key _, and a pause/continue cutting button. The function keys include multiple combinations of cutting keys and powerful cutting mode/normal cutting mode; the suction key transmits instructions to external devices through the control structure 3 to control bleeding in the surgical cavity during the operation. Suction to improve the development level of abnormal breast tissue under imaging; the sampling slot enlargement key and the sampling slot adjustment key are used to adjust the size of the sampling slot to adapt to the size of the tissue. Some tissues during the operation The size is small. If a slot with a large opening is used, it may cut into other normal tissues of the human body and cause damage. It is necessary to "adjust" or "downsize" the size of the sampling slot to adapt to the size of the tissue; the sampling slot rotates the key clockwise The counterclockwise rotation key of the sampling slot is used to control the angle of the sampling slot to adapt to the orientation of the tissue to be sampled. During the doctor's operation, the breast body will move and the abnormal tissue will move to other directions of the sampling slot. If the swing is overall controlled The handle may scratch and damage other normal tissues. Directly adjusting the angle of the sampling slot makes it easier to target abnormal tissues for sampling _. The pause cutting/continue cutting key is used to switch between continuing cutting or pausing cutting; the powerful cutting mode/normal cutting mode is used to switch between different cutting modes. For example, during the operation, the doctor needs to pause and adjust the angle of the color ultrasound to further observe the position of the tissue. He can press to pause cutting, and after confirmation, press to continue cutting to continue the operation. When encountering hard and dense tissue, you can switch to the powerful cutting mode to cut with high torque and high cutting speed. When encountering non-dense tissue, you can switch to the normal mode for cutting.

As shown in Figure 6, the power output structure 4 includes a protective cover 41, a sealing ring 42, a gear box 43, a plug 44, screws 45, a flange 46 and a wiring assembly 47; the gear box 43 is fixed to the Inside the flange 46, in order to prevent water from entering the structure of the control handle from the bottom, the protective cover 41 is used as a waterproof structure to withstand both sides of the flange 46, and the protective cover is secured through the screws 45. 41 is fixed on the bottom of the flange 46, and the protective cover 41 has a certain preset thickness, which is used to reduce the upward transmission of noise generated by the gear box 43 and reduce the vibration when the control handle is held. sense to avoid image operation experience. The protective cover 41 also serves as an isolation member between the gear box 43 and the wire harness to avoid the risk of the wire harness being drawn into the gear box 43 during the connection process. Since there is a gap in the contact surface between the lower side of the flange 46 and the lower shell 13 , a sealing ring 42 is provided on the lower side of the flange 46 . The sealing ring 42 is disposed between the lower side of the flange 46 and the lower shell 13 . On the contact surface of 13, the sealing ring 42 is used to waterproof when the flange 46 is squeezed downward, and to avoid the rigid connection between the flange 46 and the lower shell 13 to increase buffering. This prevents gear transmission from affecting the lower housing 13 and reduces vibration. In order to prevent water from flowing out from the surface hole of the flange plate 46, the plug 44 is inserted into the surface hole of the flange plate 46. The plug 44 has a T-shaped structure. One end of the plug 44 ( The big end) resists the surface hole of the flange 46 to provide waterproofing, and the other end (small end) supports the wiring assembly 47, and at the same time, due to the non-metallic material characteristics of the plug 44, plays an insulating role to prevent The creepage distance between the flange 46 and the wiring assembly 47 is insufficient, which may cause danger. After the power output structure 4 is installed, it is fixed on the lower shell 13 .

Further, the display structure 5 will give corresponding prompts before and during the operation, and at the same time cooperate with sound prompts, such as calibration, calibration completion, cutting and other actions. The above key operations will transmit the instructions to the power output structure 4 through the control structure 3 for cutting, adjusting the size and angle of the sampling slot, etc. As shown in Figure 7, the display structure 5 includes a display screen cover 51 and a display screen 52; there are steps on the upper cover cover 11, and the display cover 51 has adhesive backing or is fixed by dispensing glue after fixing. The display screen cover 51 is bonded to the step of the upper cover shell 11 , and the display screen 52 is fixed to the bottom of the display screen cover 51 through the back glue or glue dispensing of the display screen cover 51 . The data transmission line of the screen 52 is connected to the upper PCB board 6 . Full contact between the display cover 51 and the upper cover 11 ensures sealing and better waterproofing. The upper surface of the display cover 51 is lower than the mounting surface of the upper cover 11 to prevent scratches. Remove the display cover and prevent accidental touching of the display. The display screen is a color screen and will show the steps of the surgical process. For example, before the operation, it will prompt that the control handle is not assembled. After installing the matching disposable breast rotation puncture needle, it will prompt that calibration is required. You can press the first button structure 21 Or any key on the second button structure 22 will start calibration immediately. If any key is not pressed, the control handle will automatically start calibration after a short time. At this time, the display screen 52 will show that calibration is in progress. After completion, it will show that it has been calibrated and remind the doctor. You can start the operation. During the operation, there will be prompts such as cutting, suctioning, and the cutting groove is being adjusted. These prompts are displayed through text and pictures. It can be seen that the current length and angle of the cutting groove are not only convenient for new users. The operator can also see the progress of the operation more intuitively without having to use other devices to confirm the steps for using the control handle or transmit information during the operation through other medical staff. The display structure also has the function of touch control, which can Let the doctor choose to switch the surgical information parameters he wants to display.

As shown in Figure 8, the control handle also includes a connecting cable locking structure 7; the connecting cable locking structure 7 includes a line card 71, a connecting cable 72, a locking ring cover 73 and a sealing ring 74; The line card 71 is pre-installed on the connecting cable 72 through injection molding to ensure firmness. Then, after the connecting cable 72 is inserted into the upper shell 12 and the lower shell 13, the upper shell 12 and the lower shell 13 are buckled. To ensure that the wire card cannot be easily pulled out inside, the rear end surfaces of the upper shell 12 and the lower shell 13 have threads, and the locking ring 14 is rotated to the surfaces of the upper shell 12 and the lower shell 13 through the threads. , after locking, ensure the interference fit between the upper shell 12 and the lower shell 13 and the line card 71. The surfaces of the upper shell 12 and the lower shell 13 are gently inserted into the surface of the line card 71, so that the connecting cable 72 will not be twitched. The upper shell 12 and the lower shell 13 fix the connection cable, and the close contact also solves the waterproof problem of the tail end, and also reduces the separation force between the upper shell 12 and the lower shell 13 during use. The sealing ring 74 is embedded in the surface of the locking ring 14, and will not scratch the surfaces of the upper shell 12 and the lower shell 13 during the tightening process of the locking ring 14. Add the locking ring 14 during use. The friction force forms a self-locking function and will not be easily released. The locking ring 14 uses a magnetic conductor to act as a magnetic ring for the connecting cable 72. It not only serves as decoration on the outside of the connecting cable 72, but also can reduce high-frequency noise in electromagnetic compatibility. The locking ring cover 73 is connected to the locking ring 14 by being magnetically attracted to the surface of the locking ring 14 or by being tightly connected with the internal thread of the locking ring 14 to cover and decorate the locking ring 14 . It also prevents some water from flowing into the thread gaps.
