Description

Sliding lid opening grip device

The invention relates to a component of a surgical instrument, in particular to a sliding-type lid opening grip device.

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 applier unit. Stretching into the human body, and then operating the gripping unit to drive the clip-applying unit to act with its driver, and press the blood vessel clip onto the blood vessel to close the blood vessel by clamping the jaws at the front end of the clip-applying unit with the forceps inside.

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 unit 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. However, every time the blood vessel clip applier is used, the holding unit must be constructed with this clip applying unit. Abandon and cause waste.

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.
