Description

Peritoneoscope ligature clamp takes out pincers

Technical Field

The invention relates to the technical field of laparoscopic surgery, in particular to a pair of laparoscopic ligation clip taking-out forceps.

Background

At present, laparoscopic surgery is widely performed in hospitals at all levels, a ligation clip is a consumable commonly used in laparoscopic surgery, the ligation clip is a product gradually replacing a traditional metal titanium clip and is used for ligation and closure of ligation blood vessels and excision duct stumps (such as cystic ducts, ureter stumps and the like), and a similar ligation clip structure is disclosed in a patent document with an authorization publication number of CN 103356263B. However, when ligating a blood vessel or a cut duct stump using a clip, the clip needs to be removed if another blood vessel or organ is accidentally clipped during an operation or if the clip is not sufficiently clipped.

The utility model discloses a grant utility model discloses a be CN203506828U utility model provides a get clamp for ligature clamp, it includes two mutual articulated centre gripping tip (1) to get the clamp, on two relative working faces of centre gripping tip (1), be provided with a plurality of inboard antiskid tooth (13) at the most inboard correspondence that closes on articulated shaft (2) the outside correspondence of the relative working face of two centre gripping tip (1) is provided with a plurality of outside antiskid tooth (14), be smooth plane (15) that the position corresponds between inboard antiskid tooth (13) and the outside antiskid tooth (14) of two centre gripping tip (1). The utility model provides a get clamp ware can be used for opening the ligature clamp after closing and release specially, can also take out the ligature clamp after the release by the way.

However, the laparoscopic surgery belongs to a minimally invasive surgery, the surgical incision is small, and the clip taking device is required to extend into the deep position in the abdominal cavity when the ligation clip in the abdominal cavity is taken out, but the clip taking device in the utility model is shaped like a scissors and is difficult to extend into the deep position in the abdominal cavity, and the shape of the scissors causes the enlargement of the surgical incision so that the clip taking device can extend into the incision, thereby causing the too large surgical wound; and should get the clamp and press from both sides the ware and press from both sides the ligature through two centre gripping tip and carry out the centre gripping, through adding the clamping force and force the ligature to press from both sides the emergence deformation and make the trip and the dop of ligature press from both sides break away from, can cause like this to get the clamp and make the clamping-force that blood vessel or excision pipeline stub received too big, and cause the damage to blood vessel or excision blood vessel stub, cause the operation risk to increase. In addition, the position that ligature clamp placed in the abdominal cavity also probably needs special clamp to get the angle, and the above-mentioned utility model in get the clamp ware also inconvenient operation, brings the discomfort for doctor's hand posture, is unfavorable for going on smoothly of operation.
