Jawed clamp

Abstract

The invention discloses a jawed clamp, mainly comprising a jaw, a shank, a 360-degree rotary wheel, a return spring, a fixing sleeve, a push handle, a fixed handle, a pin, a mandrel; the fixed handleis connected with the push handle via the pin; the tail end of the push handle is extended into the fixed handle; a gap of the push handle is in fitly contact with a fixing sleeve fitted in the fixedhandle; the other end of the fixing sleeve is connected with the mandrel; the mandrel is sleeved with the return spring abutted between the fixed handle and the fixing sleeve; the front end of the fixed handle is connected with the shank via the 360-degree rotary wheel, the front end of the shank is fitted with the jaw, and the mandrel is passed through the shank to drive the jaw. The jawed clampis simple in structure and convenient to use and operate, has high practicality, can clamp two vascular clips at a time, allows the two vascular clips to perform clipping and tying to arrive at hemostasis such that dual safety to prevent bleeding is achieved and surgical safety is ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tiger head clip applier. Background technique [0002] In clinical practice, laparoscopy is currently one of the most widely used surgical methods, and the most frequently used instrument for vascular ligation is clip applier. After clipping a blood vessel clip, the surgeon needs to find a suitable position to clamp the other end of the blood vessel to close and clamp. The specific position of the other end of the blood vessel can only be clamped by visual inspection and feeling. One hemostatic clip needs to be removed from the abdominal cavity, and the vascular clip is reinstalled, and then put into the abdominal cavity again, so that the clips are taken back and forth, which seriously affects the operation time and efficiency. [0003] Ordinary clip applicators can only take out a single clip, which has a relatively high error rate when applying clips to stop bleeding, and...

Problems solved by technology

After clipping a blood vessel clip, the surgeon needs to find a suitable position to clamp the other end of the blood vessel to close and clamp. The specific position of the other end of the blood vessel can only be clamped by visual inspection and feeling. One hemostatic clip needs to be removed from the abdominal cavity, and the vascular clip is reinstalled, and then put into the abdominal cavity again, so that the clips are taken back and forth, which seriously affects the operation time and efficiency.

[0003] Ordinary clip appliers can only take out a single clip, which has a relatively high error rate when applying clips to stop bleeding, and the repeated use is relatively poor

However, when a single vascular clip is applied, the area of ​​the clamped blood vessel will not be in place, resulting in the problem of incomplete hemostasis, which greatly increases the risk of use
