Abstract

The invention discloses a clip applying apparatus of a blood vessel clipper. A twine hook pull rod is fixedly arranged in an outer tube. The front end of the twine hook pull rod stretches out the clipmouth part of the outer tube. Behind the clip mouthpart, a track that can accommodate at least two clip nails is arranged. Behind clip nails, a nail pushing device is arranged. The top of the nail pushing device is provided with a pushing elastic sheet. A nail loading push rod is arranged in the outer tube. The nail loading push rod is provided with a plurality of push holes that can push the pushing elastic sheet. When the nail loading push rod moves forward, the push holes push the nail pushing device forwards in sequence, the clip nails are fed into the clip mouth part; a twine hook clipping device drives the clip mouth part to clamp the clip nail; the number of parts is small; the nail pushing device does not need to be pushed by a spring; and the size and pipe diameter of the clip applying apparatus are both reduced.

Description

Technical field [0001] The invention relates to a structure of a surgical instrument, in particular to a clip applier of a blood vessel clip applier with fewer parts and capable of reducing the diameter of the device. Background technique [0002] During laparoscopic surgery, blood vessels need to be closed to avoid blood loss from the incision at the surgical site. At this time, surgical instruments that close the blood vessels, such as a blood vessel clip applier, are used to close the blood vessels. The above-mentioned method of using the vascular clip applier is mainly to extend the long rod-shaped clip applier unit of the vascular clip applier into the human body from the opening cut on the surface of the human body, and then operate the grip part to drive the clip applier to act to apply the clip The clamping part at the front end of the unit clamps the blood vessel clip that is sequentially transported inside the clamping part, and the blood vessel clip is pressed against ...
