Steel plate insertion auxiliary device, steel plate automatic insertion system and control method

Abstract

The invention provides a steel plate insertion auxiliary device, a steel plate automatic insertion system and a control method. The steel plate insertion auxiliary device comprises a plate body matched with the surface radian of a clamping part of a steel plate, wherein a mechanical arm tail end connecting part, one or more bulges and a first fixing hole are arranged on the plate body; the bulgesare matched with grooves of the clamping part of the steel plate; the first fixing hole is used for realizing the fixed connection of the auxiliary device and the steel plate; the mechanical arm tailend connecting part is fixedly connected with the tail end of a mechanical arm; a through hole is also formed in the plate body; the through hole is formed in a corresponding position of a nail placing position of the steel plate connected with a bone; and the diameter of the through hole is greater than the diameter of a nail hole of the nail placing position. The steel plate insertion auxiliarydevice used as a mechanical arm and steel plate connecting middle element is designed. The device provided by the invention has the advantages that the clamping intensity problem and the nail empty shielding problem of the mechanical arm are solved at the same time; under the guide of a navigation system, the mechanical arm is used for accurately inserting the steel plate; the repeated perspectiveis not needed; the operation safety and stability are improved.

Description

technical field [0001] The present disclosure relates to the related technical field of medical devices, and in particular, relates to a steel plate insertion auxiliary device, a steel plate automatic insertion system and a control method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The general treatment process for fractures is to reset the broken bones first, and then fix the two or more broken bones that are docked. The general method is to use the method of opening and placing steel plates. Different steel plates can be selected for different broken bones, and for Depending on the approach to the same broken bone, the selection of the plate is also different. For the LiSS steel plate, although we can insert the steel plate through a small incision, it is difficult to insert it into the proper position at one time, and often requ...

AI Technical Summary

Problems solved by technology

The inventor found that the robot can accurately place the steel plate to the optimal position, but there are not small difficulties in the automatic implantation of screws

In terms of the steel plate implantation device, the main difficulty lies in the contradiction between the clamping strength of the steel plate and the shielding of the nail hole. In order to have sufficient clamping strength between the steel plate and the robot, we often need to clamp the steel plate in a place that is large enough. With the expansion of the clamping range of the steel plate, the shielding of the nail hole is also increasing

Failure to provide enough space for the implantation of screws leads to implantation failure, multiple implantation prolongs the operation time, and reduces the efficiency of automatic plate implantation
