[0034] Reference Figure 2 - Figure 4, the force adjustment component includes a connecting sleeve 81, and the upper surface of the connecting sleeve 81 is plugged with an operating instrument 7. There are many types of operating instruments 7, and the common ones are grasping forceps, separating forceps, electric coagulation hooks, etc., which are not listed one by one in the utility model, and are all replaced by operating instruments 7. The operating instrument 7 is plugged into the center position of the upper surface of the connecting sleeve 81, and a motor 82 is provided on the upper surface of the connecting sleeve 81. The motor 82 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The output shaft of the motor 82 is fixedly connected to the worm 83. After the motor 82 is started, it can drive the worm 83 to rotate. The inner wall of the connecting sleeve 81 is rotatably connected to the threaded rod 85. The connecting sleeve 81 provides support for the threaded rod 85, and the outer wall of the threaded rod 85 is fixedly connected to the worm gear 84. Training box 3 The right surface is provided with a placement component, which facilitates the placement and taking of the operating instrument 7 and is convenient for medical staff to use. The force adjustment component also includes a connecting block 86. The top of the connecting block 86 is annular, and the lower half is a vertical plate. The lower surface of the connecting block 86 is fixedly connected to a moving block 87. The lower surface of the connecting block 86 is located at the right end of the upper surface of the moving block 87. The inner wall of the moving block 87 is elastically connected to a slide plate 89 through a compression spring 88. The slide plate 89 slides horizontally, and the left surface of the slide plate 89 is fixedly connected to a splint 810. The slide plate 89 and the splint 810 will move synchronously. There are multiple groups of force adjustment components and operating instruments 7, which are evenly distributed on the training box 3. In addition, in each group of force adjustment components, except for the connecting sleeve 81, the other components are provided with two and are symmetrically distributed left and right with the center line of the connecting sleeve 81.

[0035] Reference Figure 1 、 Figure 5 The placement component includes a placement plate 91, the inner wall of the placement plate 91 is elastically connected to a stopper 93 through a connecting spring 92, a slot 901 is opened on the right surface of the placement plate 91, and multiple groups of connecting springs 92 and stoppers 93 are provided, which are symmetrically distributed front to back with the center of the slot 901.

[0036] Reference Figure 2 - Figure 4, the connecting sleeve 81 is installed on the training box 3, the worm 83 passes through and is rotatably connected to the upper surface of the connecting sleeve 81, the worm wheel 84 and the worm 83 are meshed, the worm wheel 84 and the worm 83 are prior art, and can be implemented by technicians in this field. Since it is prior art, it will not be described in detail in this case. The rotation of the worm 83 can drive the worm wheel 84 to rotate, and the worm wheel 84 cannot drive the worm 83 to rotate, and each rotation of the worm 83 will drive the worm wheel 84 to rotate one tooth. The threaded rod 85 passes through and is threadedly connected to the right surface of the connecting block 86. When the threaded rod 85 rotates, it will drive the connecting block 86 to move horizontally. The splint 810 is set to an arc shape, and the splint 810 can be used with common ones such as electric The outer walls of the coagulation hook, separation forceps and grasping forceps fit together and can apply pressure. The left surface of the splint 810 is set to rubber material to prevent damage to the operating instrument 7. Common operating instruments 7 are larger at the top and smaller at the bottom. The moving block 87 is slidably connected to the inner wall of the connecting sleeve 81, and one end of the compression spring 88 is fixedly connected to the right surface of the slide plate 89. The other end of the compression spring 88 is fixedly connected to the inner wall on the right side of the moving block 87. When the moving block 87 approaches the slide plate 89, the slide plate 89 will gradually retract into the moving block 87 and squeeze the compression spring 88 to generate a reaction force, thereby increasing the force of the splint 810 to clamp the operating instrument 7. The slide plate 89 penetrates and is slidably connected to the left surface of the moving block 87, sliding horizontally.

[0037] Reference Figure 1 、 Figure 5 One end of the connecting spring 92 is fixedly connected to the front surface of the stopper 93, and the other end of the connecting spring 92 is fixedly connected to the inner wall of the front side of the placement plate 91. The stopper 93 passes through and is slidably connected to the rear surface of the placement plate 91. When the stopper 93 moves forward, it will retract into the placement plate 91 to release the blockage, and will squeeze the connecting spring 92 to generate a reaction force. The rear surface of the stopper 93 is set to an arc surface. When the arc surface of the stopper 93 is squeezed, the stopper 93 will retract into the placement plate 91, and the operating instrument 7 is placed in the slot 901. Because the common operating instrument 7 is larger at the top and smaller at the bottom, the common operating instrument 7 can be placed in the slot 901.

[0038] Working principle: When using this device, first start the training box 3, display screen 4 and operating table 5, then move the operating instrument 7 to the right and take it out from the slot 901. When the operating instrument 7 moves to the right, it will squeeze the arc surface of the block 93, and the block 93 will retract into the placement plate 91 to release the blockage, so that the operating instrument 7 can be taken out, and then the taken out operating instrument 7 is inserted into the connecting sleeve 81 to start surgical training.

[0039] During the training process, the display screen 4 can display the screen in the training box 3 for the medical staff to watch, and during the training process, the motor 82 will start at a fixed time. When the motor 82 starts, it can drive the worm 83 to rotate, and then drive the worm wheel 84 and the threaded rod 85 to rotate. When the threaded rod 85 rotates, it can drive the connecting block 86 and the moving block 87 to move horizontally, and the positions of the moving block 87 and the slide 89 will change. When the moving block 87 approaches the slide 89, the slide 89 will gradually retract into the moving block 87 and increase the force of the compression spring 88. Under the influence of the reaction force of the compression spring 88, the slide 89 and the splint 810 can be pushed to apply different forces to the outer wall of the operating instrument 7, so that the medical staff can feel the changes in feeling when they are disturbed by external forces of different sizes during operation. Moreover, since there are multiple groups of force adjustment components and they are facing different directions, the medical staff can also feel the changes in feeling when they are disturbed by external forces of different directions during operation, so that the medical staff can adapt to the real environment.

[0040] After the training is completed, the motor 82 can be controlled to drive the worm 83, the worm gear 84, and the threaded rod 85 to rotate, and then drive the connecting block 86, the moving block 87, the slide plate 89 and the splint 810 to move toward the edge of the connecting sleeve 81 to release the clamping of the operating device 7, and then the operating device 7 can be taken out and aligned with the slot 901 and moved from right to left. During movement, the operating device 7 will squeeze the arc surface of the block 93. When the block 93 is squeezed by external force, it will retract into the placement plate 91 to release the obstruction to the operating device 7, and will squeeze the connecting spring 92 to generate a reaction force. When the operating device 7 and the slot 901 are plugged in, the reaction force of the connecting spring 92 will push the block 93 out to limit the operating device 7. In the absence of external force, the operating device 7 will be stabilized in the slot 901.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
