Description

Technical Field

[0001] The invention relates to the technical field of medical robots, in particular to a fracture reduction robot for orthopedic auxiliary care. Background Art

[0002] A robot is an automated machine. The difference is that this machine has some intelligent capabilities similar to humans or living things, such as perception, planning, movement and coordination. It is an automated machine with high flexibility. Robots can assist or even replace humans in completing dangerous, heavy and complex tasks, improve work efficiency and quality, serve human life, and expand and extend the scope of human activities and capabilities.

[0003] Fracture reduction surgery actually refers to the treatment of open reduction and internal fixation for patients with fractures. For some patients with severe fractures, surgery is required. At this time, the fracture ends need to be completely cut and exposed, and the fracture ends of the patient need to be reduced accordingly under direct vision to achieve the best anatomical reduction. After that, a series of internal fixation devices, such as steel plates, screws, Kirschner wires, etc., are needed to firmly fix this place.

[0004] At present, with the increasing maturity of the robotics industry, the types of medical robots are becoming more and more extensive. Among them, the auxiliary fracture reduction robot developed for fracture reduction surgery can assist doctors in performing surgery, and is divided into different types of fracture reduction robots due to different auxiliary functions. In the prior art, after using a steel plate to fix the patient's fracture position, it is necessary to use screws to fix the steel plate. Generally, the above process is performed by a doctor, but the doctor can only take one or two screws at a time, which greatly affects the efficiency of the operation.

[0039] The working principle of the present invention is as follows: first, the screws are stored in the cavities 402 of the storage tank 401 through the feeding port 206 until all the cavities 402 are fully loaded with screws;

[0040] When performing fracture reduction surgery, the robot can assist in the automatic installation of screws. Specifically, with the cooperation of the first free end 103 and the second free end 104, the robot will move the storage box 201 to a suitable position, that is, directly above the position where the screws are to be installed, and then start the drive motor, which will drive the drive gear 203 to rotate, and the drive gear 203 will then drive the push rod 301 to move downward. When the round table 302 at the bottom of the push rod 301 moves to contact the screw inside the push block 3041, the round table 302 will absorb the screw through the magnetic suction part 303;

[0041] Then the push rod 301 will continue to move. During this process, the push rod 301 will squeeze the bottom plate 3043 through the screw to drive the bottom plate 3043 to open, thereby realizing the movement of the screw, until the push rod 301 drives the screw to be installed into the screw hole on the steel plate, and then the reset can be performed;

[0042] In the above process, as the push rod 301 moves, the push rod 301 will squeeze the push block 3041, so that the push block 3041 moves into the storage chamber 205. After the push block 3041 moves, it will squeeze the return spring 308 and make its placement chamber 3042 move to just below the cavity 402 of the storage tank 401. At this time, a group of screws stacked in the cavity 402 will fall into the placement chamber 3042 of the push block 3041 under the action of gravity, thus completing the automatic replenishment of the push block 3041. As the push rod 301 is reset, the push block 3041 will be reset again under the action of the return spring 308 and move out of the storage chamber 205 to just below the push rod 301, so as to facilitate the push rod 301 to take the screws next time.

[0043] It is worth noting that when one set of screws moves out following the pusher block 3041, another set of screws will fall into the disinfection block 4071 between the extension plate 3044 and the cavity 402, and the movement of the pusher block 3041 will drive the driven gear ring 4073 to rotate through the driving tooth plate 4074, that is, drive the disinfection block 4071 to rotate, and the rotation of the disinfection block 4071 will perform rotational friction disinfection on the inner screws through the disinfection cotton 4072, thereby improving the quality of the screws, that is, improving the quality of the fracture reduction surgery;

[0044] In addition, after all the screws in a group of cavities 402 are used up, the electric guide rail 405 can be started to drive the slider 406 to move, and after the slider 406 moves, it will drive the storage tank 401 to rotate through the synchronization rod 4061 until the second group of fully loaded cavities 402 rotate to the top of the push block 3041.
