Description

Sliding lid opening grip device

Technical field

The present invention relates to the technical field of surgical instruments, in particular to a sliding type lid opening grip device.

Background technique

During laparoscopic surgery, the blood vessel needs to be closed to avoid blood loss from the incision at the surgical site. At this time, a blood vessel clip applier is used to close the blood vessel. The blood vessel clip applier uses a long rod-shaped clip when used. The unit extends into the human body, and then the gripping unit is operated to drive the clip applying unit to act with its driver, and the clamp at the front end of the clip applying unit clamps the inner forceps to press the blood vessel clamp on the blood vessel to close the blood vessel.

The aforementioned vascular clip applier will extend into the human body during use. In order to avoid blood contamination, it is generally designed as a disposable structure for one-time use, but because the back end of the clip applier is encapsulated in the grip device , Even if the clip applying unit can be separated from the driver of the holding unit, and the holding unit is not contaminated with blood, it does not need to be discarded, but every time the blood vessel clip applier is used, the holding unit must be configured with the clip applying unit. Abandon and cause waste.

Summary of the invention

Since the existing vascular clip applier has a disposable structure, its holding unit cannot be reused, which causes a waste problem. For this reason, the present invention designs a gun handle device with a sliding cover body and can provide a clip-applying unit installation after the cover is opened, so as to achieve the economic effect of the gun handle device being reusable.
