Suture-assisted manipulation device and method of operation thereof

Abstract

The present application provides an auxiliary suture operating device and its operating method, including a locking device with a locking structure and a locking control structure, and a thread trimming device with a thread trimming structure and a thread trimming control structure, wherein the locking control structure The thread cutting control structure can move relative to the locking structure to control the thread cutting structure to cut the suture thread. Thereby, the present application has the advantages of simple operation and high locking reliability of the suture thread, and can improve operation safety.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular to a suture auxiliary operation device and an operation method thereof. Background technique [0002] With the increasing popularity of minimally invasive surgery and interventional surgery, it is often necessary to knot or lock the sutures in the patient's body during the operation, that is to say, the locking operation of such sutures usually needs to be done in a small, flexible , completed in the remote channel. [0003] The prior art discloses a suture locking device, which adopts a rigid collet to clamp the locking nail, so as to achieve the purpose of locking the suture. However, when this locking device needs to be applied to a smaller operation channel, the clamping force provided by the locking device is insufficient to clamp the suture due to the limitation of the size of the parts. Or, because the locking effect provided by the l...

AI Technical Summary

Problems solved by technology

However, when this locking device needs to be applied to a smaller operating channel, the clamping force provided by the locking device is not enough to clamp the suture due to the limitation of the size of the parts

Or, increased surgical risk due to unreliable locking provided by the locking device

In addition, due to the large number of parts of the existing locking device, the complex matching relationship, and the cumbersome manufacturing process of the device, the above-mentioned technical problems also limit the further reduction of the size of the parts; in addition, the suture thread provided by the existing locking device The locking and thread trimming actions are simultaneously completed through one driving action, which cannot satisfy the repeatability of the locking action when the locking position is not optimal
