Description

Technical Field

[0001] This utility model relates to the field of medical training equipment technology, specifically to a laparoscopic shearing training model and simulation training device. Background Technology

[0002] In the field of medical training, especially in surgical skills training, cutting is a fundamental and crucial skill. Traditional cutting training mainly relies on on-site guidance from experienced surgeons during actual operations, but this method has many limitations, such as high patient safety risks and limited training opportunities. With the development of technology, medical simulators have emerged, providing medical personnel with a safer and more efficient training method. Cutting circles under endoscopy is a basic but important training exercise in laparoscopic surgery, primarily used to improve the surgeon's fine motor skills and hand-eye coordination. A common training method involves drawing one or more circles on a substrate such as paper or gauze. One hand holds a dissecting forceps or clamping forceps to grasp the substrate, while the other hand holds scissors to cut along the drawn circles until a complete circle is cut out. During the cutting training assessment, three concentric circles are drawn on the substrate. The middle line is the trajectory to be cut, and the inner and outer lines are the boundary lines. The trainee is required to complete the cutting along the middle circle within a specified time, ensuring the edges are smooth and do not exceed the inner and outer boundary lines. The assessment results need to be checked and verified by the assessors one by one, which is a lot of work and the accuracy of judging and detecting edge positions is low, making it difficult to accurately evaluate the operation of medical staff, resulting in poor training effect. Utility Model Content

When the blades of the simulated scissors touch the conductive elements in the boundary detection areas, the simulated scissors, the conductive elements, and the main control board form a closed loop.

[0006] Furthermore, the main control board is equipped with a signal acquisition module, a signal processing module, a scoring module, and a data transmission module; the signal acquisition module is used to acquire electrical signals cut to the boundary detection area and send them to the signal processing module, the signal processing module processes the acquired electrical signals, the scoring module determines whether to deduct points based on the data processed by the signal processing module, and the data transmission module is used to send the scoring results to the host computer.

The center and four corners of the simulated shearing consumable are respectively provided with positioning holes. The central positioning hole is adapted to the positioning post A, and the other positioning holes are adapted to the positioning post B.

[0008] Furthermore, the simulated shearing consumable is made of silicone material, and conductive elements are embedded in the simulated shearing consumable along the boundary detection area.

[0013] Furthermore, the clamping tool is a separating clamp or a gripper.

[0014] The beneficial effects of this utility model are:

[0015] This utility model's endoscopic shearing training model incorporates conductive elements placed along the contour of the shearing zone within the simulated shearing consumable. These conductive elements and the simulated shears are electrically connected to the main control board. During the shearing process, when the simulated shears cut into the conductive elements in the boundary detection zone, the simulated shears, conductive elements, and the main control board form a closed loop. The main control board can detect changes in electrical signals. By acquiring, processing, and analyzing these electrical signals, the main control board can accurately determine whether the shearing action exceeds the boundary of the shearing zone, thus achieving real-time and precise monitoring of the shearing operation.

Touching the control switch before or after completing the specified action will turn the timing on or off and record the time to complete the specified action, providing an important basis for the main control board to make comprehensive scores.

During shearing training, under the laparoscope, a separation forceps and a simulated pair of scissors are used together. The simulated scissors are used to cut the simulated shearing consumable 2 along the shearing zone 22 until the inner circle is cut off. During the shearing process, when the blade of the simulated scissors touches the conductive element 3 in the boundary detection zone 21, the simulated scissors, the conductive element and the main control board form a closed loop. The main control board can detect the change in electrical signal. The main control board determines whether the simulated scissors have cut into the boundary detection zone based on the change in electrical signal data, and records the number of times the scissors have cut into the boundary detection zone.

[0024] In one embodiment, a positioning post A11 is arranged at the center of the base plate 1, and four positioning posts B12 are arranged in a rectangle around the positioning post A11. The center and four corners of the simulated shearing consumable 2 are respectively provided with positioning holes.

The conductive elements in the simulated shearing consumable 2 are electrically connected to the main control board through the positioning posts A and B respectively.

[0025] Preferably, the simulated shearing consumable 2 is made of silicone material, and the conductive element 3 is embedded in the simulated shearing consumable 2 along the boundary detection area 21. The conductive element 3 is copper foil, aluminum foil, ITO film or other conductive film.

[0026] Furthermore, it also includes a timing module, which is electrically connected to the main control board. The control switch 4 of the timing module is located on the upper surface of the base plate 1; preferably, the control switch 4 of the timing module is a metal contact switch.

Then, use the dissecting forceps in conjunction with the simulated scissors to cut off the inner circle, and use the dissecting forceps to remove the cut inner circle outside the training box. Touch the control switch 4 of the timing module again to end timing. The main control board monitors the changes in electrical signals during the shearing process, determines whether the simulated scissors have cut into the boundary detection area based on the electrical signal change data, records the number of times the cutting has reached the boundary detection area, gives a corresponding score, and transmits the score result to the host. Place the instrument, fold the removed inner circle into a long strip, and place it in the designated position of the ending device. At this point, the laparoscopic shearing operation is considered complete, and the score result can be viewed on the display screen.
