Quick-assembly flange with non-return mechanism for orthopedic surgery robot

Abstract

The invention discloses a fast-assembly flange with a non-return mechanism for an orthopedic surgery robot. The fast-assembly flange comprises a positioning mechanism, a locking mechanism, the non-return mechanism and a releasing mechanism. A positioning pin is arranged on the positioning mechanism and is used for being matched with an operation part to play a role in limiting rotation of the operation part; the locking mechanism is provided with a center-through hole which is used for being matched with the positioning mechanism; a closing opening is formed in the upper portion of the locking mechanism and used for being matched with an operation part to achieve the clamping effect. The non-return mechanism is a locking cylinder matched with a spring, is circumferentially arranged in the locking mechanism and is used for preventing the locking mechanism from reversely rotating; the releasing mechanism is a thin-wall circular ring with tenons distributed on the inner circumference. When an operation part needing to be installed is placed in the fast-assembly flange, the locking ring is rotated. When the locking ring is screwed to a proper position, the closing opening above the locking ring is downwards attached to the working part, meanwhile, under the action of the non-return mechanism, movement of the locking ring in the circumferential direction is limited, and the working part is locked.

Description

technical field [0001] The invention relates to the technical field of quick-installation devices for orthopedic surgical instruments, in particular to hand tools for orthopedic surgery, in particular to a quick-installation flange for orthopedic surgical robots with a non-return mechanism. Background technique [0002] As people pay more and more attention to their own health problems, the demand for using robotic technology to assist surgery in specific scenarios is increasing. During the use of the surgical robot, the robotic arm and surgical instruments need to be used together to help the doctor complete the operation. However, most surgical instruments cannot be directly assembled at the end of the robotic arm, and need to be used with corresponding adapters. This connection robotic arm The adapters for surgical instruments and tools are called quick-fit flanges. [0003] Most of the existing fast-installation flange mechanisms are designed in the form of dovetail gro...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing quick-fit flange mechanisms are designed in the form of dovetail grooves. This design method is difficult to process and the processing accuracy is not high. The error of processing accuracy may lead to a decrease in installation accuracy.

After the initial assembly is completed, it is necessary to perform secondary fastening through locking mechanisms such as bolts. The installation process is not simple enough, and a lot of time will be wasted during the operation.

In addition, there are scenes of repeated disassembly and assembly of surgical instruments in the actual use process. If it is necessary to disassemble the surgical machine, it will be difficult and time-consuming
