Description

Gallbladder stone removal simulation surgery training device

This invention relates to a training tool, particularly a bile duct stone removal simulation surgery training device that provides medical personnel with a bile duct model on an abdominal module to simulate bile duct stone removal surgery.

Endoscopic techniques are widely used in various surgical procedures due to their advantages of small incisions and minimal bleeding. However, cholangioscopy is a technique specifically used to observe and treat diseases of the common bile duct, and its operation requires extremely high skill. Therefore, traditionally, the actual operation of cholangioscopy has mostly relied on observing others' operations, performing the operation oneself, or performing the operation on animals. However, these methods have problems such as ethical concerns, resource limitations, and inconsistent learning quality.

In recent years, an endoscope has been inserted into the mouth, through the esophagus and stomach, to reach the second part of the duodenum. After locating the exit of the bile and pancreatic ducts, a contrast agent is injected into the bile and pancreatic ducts through a catheter to assess whether there are lesions in the bile ducts and pancreatic ducts, or to determine whether there are stones, stenosis, or other lesions. There are more and more cases where diseases can be diagnosed and treated simultaneously. However, compared to the above techniques, general practitioners have much less experience than senior physicians. However, not every patient can accept the above surgical method of bile and pancreatic stone removal through endoscopy. For example, patients who have undergone gastrointestinal resection and reconstruction surgery for other diseases cannot use the above method, or patients with unstable vital signs who need to manage bile duct stones and related complications.

Furthermore, considering the maturity and advancement of 3D printing technology today, medical staff can use CT images of patients with gallstones, then reconstruct and finely adjust them in 3D, and finally use 3D printing technology to create models including the common bile duct, intrahepatic and extrahepatic bile ducts, and part of the duodenum. Therefore, it is necessary to provide a teaching tool with realistic bile duct materials and anatomical locations for cholangioscopy to overcome the lack of prior knowledge.

The purpose of this invention is to provide a biliary stone removal simulation surgery training device that simulates the patient's biliary tract structure to provide medical staff with training in biliary stone removal surgery via choledochoscopy.

To achieve the above objectives, the present invention provides a bile duct stone removal simulation surgery training device for medical personnel to perform bile duct stone removal surgery training based on the location of stones in the patient's bile duct. The bile duct stone removal simulation surgery training device mainly comprises: an abdominal cavity module having a receiving space and at least one through-hole, the through-hole being located through the peripheral wall of the abdominal cavity module and communicating with the receiving space; and a bile duct module assembled within the receiving space of the abdominal cavity module, the bile duct module including a first connecting tube unit and a bile duct unit, one end of the first connecting tube unit being connected to and communicating with the bile duct unit, and the other end of the first connecting tube unit being assembled into the abdominal cavity module. One of the through holes; and a control module is disposed in the accommodating space of the abdominal cavity module, the control module comprising a processing unit, an alarm unit and at least one first sensing unit, the processing unit being electrically connected to the alarm unit and the first sensing units, the first sensing units being respectively disposed on the inner wall of the bile duct unit of the bile duct module, wherein the first sensing units are for sensing changes in physical quantities of the wall of the bile duct unit; wherein, when the processing unit processes and calculates that the changes in physical quantities returned by the wall of the bile duct unit sensed by the first sensing units exceed a set pressure valve value, the processing unit controls the alarm unit to generate an alarm signal.

Furthermore, the bile duct unit is composed of a plurality of bile duct bodies, and each bile duct body has at least one connecting portion, which is connected to another connecting portion of another adjacent bile duct body.

Furthermore, the bile duct module includes a second connecting pipe unit, one end of which is connected to the bile duct unit and the other end of which is connected to a circulation module, wherein the second connecting pipe unit is provided with another through hole.

Furthermore, the circulation module includes a liquid storage unit and a pump unit, with one end of the pump unit connected to the liquid storage unit and the other end connected to the second connecting pipe unit, for transporting the liquid stored in the liquid storage unit to the bile duct unit through the connected second connecting pipe unit, or for recovering the liquid in the bile duct unit to the liquid storage unit through the second connecting pipe unit.

Furthermore, the pump unit is electrically connected to the processing unit.

Furthermore, a stone unit can be housed within the bile duct unit, and a second sensing unit is provided on the outer periphery of the stone unit. The second sensing unit is used to sense the change in contact area and transmit the change in contact area to the processing unit. When the processing unit receives and processes the change in contact area returned by the second sensing unit, which is greater than a contact area change threshold, the processing unit controls the warning unit to generate a warning signal.

Furthermore, these first sensing units are respectively disposed on the inner wall surface of the bile duct body.

Furthermore, the bile duct body has a recessed groove formed in one of the connecting portions.

This bile duct stone removal simulation surgery training device primarily utilizes 3D printing technology to manufacture the bile duct module based on the patient's CT scan data. The stone unit is positioned according to the location of the stone to be removed, corresponding to the bile duct unit. Specifically, the stone unit is inserted through the first connecting tube unit protruding from the through-hole. The stone unit is then adjusted to align with the corresponding bile duct body. A choledochoscope is then inserted through the first connecting tube unit to simulate bile duct stone removal surgery. When the choledochoscope contacts the inner wall of the bile duct body... Once the first sensing unit detects the stone, the processing unit will process and calculate whether the change in the physical quantity it sends back exceeds the set pressure valve value to determine whether to control the alarm unit to issue an alarm signal, or whether the change in the contact area of the stone unit exceeds the contact area change valve value to determine whether the stone removal is successful and to issue an alarm signal to remind the user. Furthermore, the circulation module can provide the required amount of fluid and the pressure value of the inner wall of the bile duct unit. Therefore, the bile duct stone removal simulation surgery training device of this invention is a reusable teaching and demonstration platform that complies with relevant ethical standards.

A bile duct module 20 is assembled within the accommodating space 11 of the abdominal cavity module 10 (see Figures 1 to 4). The bile duct module 20 includes a first connecting pipe unit 21, a second connecting pipe unit 22, and a bile duct unit 23. One end of the first connecting pipe unit 21 is connected to and communicates with the bile duct unit 23, and the other end of the first connecting pipe unit 21 is assembled into one of the through holes 12 of the abdominal cavity module 10. One end of the second connecting pipe unit 22 is connected to and communicates with the bile duct unit 23, and the other end of the second connecting pipe unit 22 is assembled into another through hole 12 of the abdominal cavity module 10. The bile duct unit 23 can be... The bile duct body 231 can be integrally formed, or further, it can be composed of a plurality of bile duct bodies 231. Each bile duct body 231 has at least one connecting portion 232, which is connected to another connecting portion 232 of another adjacent bile duct body 231. Furthermore, the bile duct body 231 has a recessed annular groove 233 in one of its connecting portions 232. The annular groove 233 can lock another bile duct body 231. Also, referring to Figure 4, the wall of the bile duct body 231 can be assembled to another bile duct body 231, so that the annular groove 233 on the wall of one bile duct body 231 can lock the other bile duct body 231, but this is not a limitation.

A circulation module 30, one end of which is connected to the other end of the second connecting pipe unit 22 (see Figures 1 to 5), includes a liquid storage unit 31 and a pump unit 32. One end of the pump unit 32 is connected to the liquid storage unit 31, and the other end is connected to the second connecting pipe unit 22. The pump unit 32 is used to transport the liquid 200 stored in the liquid storage unit 31 to the bile duct unit 23 through the connected second connecting pipe unit 22, or to return the liquid 200 in the bile duct unit 23 to the liquid storage unit 31 through the second connecting pipe unit 22.

A stone unit 40 is accommodated within the bile duct unit 23 to simulate the location of a patient's gallstones within the bile duct unit 23. A second sensing unit 41 is located on the periphery of the stone unit 40, and this second sensing unit 41 is used to sense changes in the contact area.

A control module 50 is disposed in the accommodating space 11 of the abdominal cavity module 10. The control module 50 includes a processing unit 51, an alarm unit 52, and a plurality of first sensing units 53. The processing unit 51 is electrically connected to the alarm unit 52 and the first sensing units 53. The first sensing units 53 are respectively disposed on the inner wall of the bile duct unit 23 of the bile duct module 20, that is, the inner wall of the bile duct body 231. The first sensing units 53 sense the physical quantity changes of the wall of the bile duct unit 23. The processing unit 51 may be electrically connected to the pump unit 32, but is not limited thereto.

Specifically, when the processing unit 51 processes and calculates the physical quantity change returned by the wall of the bile duct unit 23 by the first sensing unit 53, which exceeds the set pressure valve value, the processing unit 51 controls the warning unit 52 to generate a warning signal. When the processing unit 51 processes and calculates the change in contact area returned by the second sensing unit 41, if the change in contact area returned by the second sensing unit 41 is greater than a contact area change valve value, the processing unit 51 controls the warning unit 52 to generate a warning signal.

First, please refer to Figures 1 through 4. The bile duct stone removal simulation surgery trainer 100 of this invention primarily utilizes 3D printing technology and the patient's CT scan data of the bile duct to create a bile duct module 20 that resembles the patient's bile duct structure. Please refer to Figures 2 through 4. This bile duct module 20 can be assembled in segments as needed; therefore, adjacent bile duct bodies 231 can be connected via these segments. The bile duct unit 23 is formed by assembling parts 232, and can be locked onto the connecting part 232 of another bile duct body 231 by means of the annular grooves 233. The first connecting pipe unit 21 and the second connecting pipe unit 22 are respectively assembled on the corresponding bile duct body 231 and then protrude from the corresponding through hole 12. Please refer to Figure 5. The bile duct module 20 can also be integrally formed, and the first connecting pipe unit 21 and the second connecting pipe unit 22 are also integrally formed. The element 22 is also connected to the corresponding connecting part 232 of the bile duct unit 23. Please refer to Figure 1. The inner wall surface of the bile duct body 231 of the bile duct unit 23 is provided with the first sensing unit 53, while the outer peripheral surface of the stone unit 40 is provided with the second sensing unit 41. Therefore, after the medical staff places the bile duct module 20 into the receiving space 11 of the abdominal cavity module 10, the stone unit 40 protrudes from one end into the through hole 12. The first connecting unit 21 is inserted, and the stone unit 40 is adjusted to the position of the patient's stone in the bile duct body 231 corresponding to the bile duct unit 23. The circulation module 30 delivers the liquid 200 in the storage unit 31 to the bile duct unit 23 as needed through the pump unit 32, or recovers the liquid 200 from the bile duct unit 23. The processing unit 51 processes and calculates according to the pressure value returned by the first sensing units 53.

Furthermore, when medical staff begin the simulation of choledochotomy, the choledochoscope is inserted through the first connecting unit 21. Therefore, when the choledochoscope contacts the first sensing units 53 on the inner wall of the bile duct body 231, the first sensing units 53 will sense the physical changes in the wall surface and provide these changes to the processing unit 51. The processing unit 51 will process and calculate whether the returned physical change exceeds the set pressure valve value, and then decide whether to control the alarm unit 5. 2. When the cholangioscopy successfully removes the stone, the second sensing unit 41 of the stone unit 40 will provide the change in contact area to the processing unit 51. The processing unit 51 will process and calculate whether the change in contact area exceeds the set threshold value to determine whether the stone removal is successful and issue an alert signal. Therefore, the bile duct stone removal simulation surgery training device 100 of this invention is a reusable teaching and demonstration platform that complies with relevant ethical standards.

In summary, the bile duct stone removal simulation surgery trainer 100 of this invention mainly uses 3D printing technology to manufacture the bile duct module 20 based on the patient's CT image data of the bile duct. The stone unit 40 is positioned at the corresponding location of the bile duct unit 23 according to the location of the stone to be removed, that is, the stone unit 40 is self-protruding. A choledochoscope is inserted into the first connecting tube unit 21 of the through-hole 12, and the stone unit 40 is adjusted to correspond to the bile duct body 231 of the bile duct unit 23. A simulation of bile duct stone removal surgery is then performed by inserting the choledochoscope through the first connecting tube unit 21. Specifically, when the choledochoscope contacts the first sensing units on the inner wall of the bile duct body 231... 53. The processing unit 51 will process and calculate whether the change in the physical quantity it sends back exceeds the set pressure valve value to determine whether to control the warning unit 52 to issue a warning signal, or whether the change in the contact area of the stone unit 40 exceeds the contact area change valve value to determine whether to issue a warning signal to remind that the stone removal was successful. Moreover, the circulation module 30 can provide the required volume of liquid 200 to the bile duct unit 23 and the required pressure value to the inner wall of the bile duct body 231 from the second connecting pipe unit 22.
