Background technique

Orthopedic devices generally refer to professional medical devices specially used for orthopedic surgery. According to the classification of the State Food and Drug Administration, it is often divided into: Class I; Class II and Class III. According to the use and performance, it is mainly divided into orthopedic knives, orthopedic scissors, orthopedic forceps, orthopedic hooks, orthopedic needles, orthopedic scrapers, orthopedic cones, orthopedic drills, orthopedic saws, orthopedic chisels, orthopedic. Files/shovels, active instruments for orthopedics, etc.

working principle:

Step 1: Through the design of the wound mechanism 1 and the clamping mechanism 2, the doctor cuts the wound with a scalpel when performing minimally invasive surgery, and then inserts the two wound plates 101 into the wound surface correspondingly, so that the wound pad 102 is placed under the skin of the patient's wound, and then the clamping plate 1 201 is sleeved on the front and rear of the wound mechanism 1, and then the threaded column 1 203 is driven to rotate through the rotating baffle 204, so that the clamping plates 1 201 on the front and rear sides are close to each other, thereby squeezing The pressure wound plate 101 makes the two wound plates 101 far away from each other, so that the wound plate 101 supports the wound surface and gradually brings the wound surface into a circle, which replaces the direct surgical perforation, so that after the operation, the patient’s skin does not There will be something missing, which is convenient for the doctor to suture the wound, and at the same time can save the stage of waiting for skin production. Compared with the perforation surgery, the above-mentioned structure assists the perforation, so that the patient can recover faster.

Step 2: After the wound is opened, the adjustment mechanism 3 is clamped on the wound pad 2 103, and then the medical staff can use the operating lever mechanism 7, nail fixing mechanism 8 and The universal mechanism 9 docks the broken bone of the patient. Through the different connections of the first operating mechanism 4 and the second operating mechanism 6, the adjusting ring 301 is first facing the wound plate 101, so that the adjusting ring 301 is facing the fractured part of the bone. The operating mechanism one 4 is also located at the center of the adjustment ring 301, so the doctor can accurately locate the fractured bone of the patient through the operating mechanism one 4. In addition, the operating mechanism two 6 is connected with the operating mechanism one 4 through the telescopic mechanism 5, thus The operating lever mechanism 7 controlled by the operating mechanism 2 6 can move arbitrarily at the inner ring of the adjustment ring 301, so the doctor performs surgery through the operating lever mechanism 7 inside the operating mechanism 4 and the operating mechanism 2 6. On the one hand, the telescopic mechanism 5 The connection of the operating mechanism 2 6 allows the operating rod mechanism 7 inside the operating mechanism 6 to move arbitrarily under the control of the doctor. On the other hand, the connection of the telescopic mechanism 5 makes the movement between the operating mechanism 2 6 and the operating mechanism 1 4 more standardized. Thereby effectively reducing the error of the doctor's hand-held operation, helping the doctor to improve the error tolerance rate, and increasing the standardization of the operation.

The third step: through the design of operating mechanism one 4 and operating mechanism two 6, the operating lever mechanism 7 controlled by the rotating ball 403 can rotate with the center of the operating ring 401 as the axis, and in addition through the rotation of the rotating ball 403 and the ball groove 402 connection, so that the rotating ball 403 can also rotate arbitrarily within the range controlled by the ball groove 402; in addition, through the connection between the telescopic mechanism 5 and the operating mechanism one 4, the operating mechanism two 6 can take the operating mechanism one 4 as the axis and the telescopic mechanism 5 The length of the radius is the circular motion at any angle, so that with the cooperation of the first operating mechanism 4 and the second operating mechanism 6, the doctor can control the operating rod mechanism 7 to move to any range defined by the wound plate 101, so that the device can The doctor holds the operating rod mechanism 7 to move in all directions, which is convenient for the doctor to perform surgery and increases the auxiliary adjustment range of the device.

Step 4: Through the design of the operating lever mechanism 7 inside the operating mechanism 1 4 and the operating mechanism 2 6, the doctor can hold the operating lever mechanism 7 with one hand when performing surgery on the patient, or operate with both hands The rod mechanism 7 is used for coordinating operations, and through the socket operation rod mechanism 7 of the operating mechanism 4 and the operating mechanism 2 6, the doctor has a fulcrum of control when holding the operating rod mechanism 7, so that the doctor can control the operating rod mechanism 7 It is more convenient and stable to hold and operate, thus effectively reducing the difficulty of the doctor's operation and effectively assisting the doctor to perform the operation.

The fifth step: through the cooperation of the operating lever mechanism 7, the nail fixing mechanism 8 and the universal mechanism 9, at first by rotating the operating lever mechanism 7 in the operating mechanism two 6, the tip of the nail fixing mechanism 8 in the operating mechanism two 6 Turn up, clamp the nail and the nail plate by the nail fixing mechanism 8 and put it into the patient's bone injury, then perform positioning through the nail fixing mechanism 8 in the operating mechanism two 6, and pass through the operating mechanism one 4 The fixed nail mechanism 8 first pulls up the pull ring 705 in the operating mechanism one 4, and the pull ring 705 drives the stay rope 707 to move up, so that the upper end of the fixed plate 804 shrinks toward the position of the fixed head 801, thereby opening the fixed plate The lower end of 804 makes the fixed plate 804 clamp another fixing nail on the top plate, then carry out the fixing of another fixing nail by operating lever mechanism 7 in operating mechanism one 4, then by adjusting the operating lever in operating mechanism two 6 Mechanism 7 fixes the fixation nails. Through the function of the valgus of the operating mechanism 2 6 and the clamping of the fixation nails by the fixation mechanism 8, the operating lever mechanisms 7 on both sides can cooperate with each other, thereby rejoining the patient's fractured bones. , which simplifies the operation of the operation and improves the efficiency of the operation.
