Deep suture pressing apparatus for liver surgery laparotomy

Abstract

The invention belongs to the field of medical appliances and relates to an apparatus used for suture pressing during deep knotting in liver surgery laparotomy. The apparatus is a blunt apparatus with one end similar to a fingerstall (which can be fastened at the tail finger joint of the index finger) and a U-shaped opening in the top end; and the apparatus is configured with different fingerstall types and connecting rods of different lengths. In order to solve the problem of inconvenient knotting operation for relatively deep parts such as the right posterior lobe or the caudate lobe of the liver in existing liver surgery operation, the invention provides the deep suture pressing apparatus. The deep suture pressing apparatus is characterized in that a U-shaped suture pressing apparatus is arranged at the head end, so that no sliding is ensured in suture pressing during knotting and a suture knot is firm; the head end is round and blunt, so that the tissues are not injured during operation; and the different fingerstall types and the connecting rods of the different lengths are configured, so that operators can conveniently select the proper types according to self conditions, wearing is convenient, and the problem of deep knotting in the liver surgery is exactly solved. The suture pressing apparatus is easy to process and manufacture, low in cost and high in practicality, and has a wide market prospect.

Description

[0001] Technical field [0002] The invention relates to a thread crimping device used for deep ligation in laparotomy of liver surgery. Especially when operating on the right posterior lobe of the liver, caudate lobe, etc., where the position is deep, the operating field of view is small, and the surgical incision is small, a thread crimping device is used for knotting during surgery. It is convenient for deep knotting and crimping during the operation, which is convenient for operation and improves operation efficiency. It belongs to the technical field of medical equipment. Background technique [0003] During laparotomy in liver surgery, especially when the operation site is the right posterior lobe or caudate lobe of the liver, or when the liver is shrunk due to cirrhosis, the operation site is often deep, and deep knotting is required. In some cases ( Such as the patient is obese), the incision is small, which increases the difficulty of knotting during the operation. ...

AI Technical Summary

Problems solved by technology

[0003] During laparotomy in liver surgery, especially when the operation site is the right posterior lobe or caudate lobe of the liver, or when the liver is shrunk due to cirrhosis, the operation site is often deep, and deep knotting is required. In some cases ( Such as the patient is obese), the incision is small, which increases the difficulty of knotting in the operation, if the deep knot is not firm, the thread knot will fall off, which will easily cause postoperative bleeding, biliary fistula and other consequences

In the past, in laparotomy for liver tumors, the crimping line was performed by the surgeon's fingertips. During the operation, the finger sometimes slipped out when pressing down, or the part was deep, the length of the finger was limited, and the incision was small, so it was difficult to press down, or is difficult to operate

In this case, it is easy to cause the knot is not strong enough, or the knot is too tight, which will damage the tissue (vascular, bile duct system, etc.)

At present, there is no clinically available thread crimping device for knotting liver laparotomy, often relying on the surgeon's personal skills
