Abstract

The invention discloses a clamping device of a blood vessel clip applier. A jaw pull rod is fixed in an outer tube, and the front end of the jaw pull rod is combined with a jaw extending out of the outer tube. There is a track for accommodating more than two nails at the rear, a nail pusher is provided behind the nails, a push shrapnel is arranged on the top of the nail pusher, and a nail-on push rod is arranged inside the outer tube. The push rod is provided with a plurality of push holes that can push the push shrapnel. When the nail push rod moves forward and backward, the nail pusher can be pushed forward with each push hole in turn, so that the clamp nails enter the jaw respectively. , and use a jaw clamper to drive the jaw part to clamp the nail, and use a structure with fewer parts and no need for a spring to push the nail pusher to form a clamping device, so that the clamping device can reduce the diameter of the pipe to a small size effect of transformation.

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 which has fewer parts and can reduce the diameter of the device. Background technique [0002] During laparoscopic surgery, blood vessels need to be closed to prevent blood loss from the incision at the surgical site. At this time, surgical instruments for closing blood vessels, such as vascular clip appliers, are used to close the blood vessels. The use method of the above-mentioned blood vessel clip applier is mainly to insert the long rod-shaped clip applier unit of the blood vessel clip applier into the human body through the opening cut on the surface of the human body, and then operate the part of the handle to drive the clip applier unit to move to apply the clip. The clamping part at the front end of the unit clamps the blood vessel clips that are sequentially delivered to the inside of the clamping part, and the blood v...
