Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an improved common bile duct stone removal mesh forceps for laparotomy. Background Art

[0002] Laparoscopic common bile duct lithotripsy is a surgical procedure that clears and removes stones in the common bile duct through the cystic duct via abdominal puncture. It is mainly used to treat common bile duct stone disease. In laparoscopic common bile duct stone surgery, it is often necessary to use a laparoscopic stone removal net to remove stones in the common bile duct. There are at least the following disadvantages in the use of existing traditional lithotripsy forceps: 1. The existing traditional lithotripsy forceps cannot achieve the containment effect of the stone removal net, especially when encountering muddy or fragmentary stones, simple clamping cannot clamp out stones multiple times; 2. The existing lithotripsy forceps are not easy to adjust the length of use. Therefore, we have introduced a new improved common bile duct stone removal net forceps for open surgery. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An improved common bile duct stone removal net forceps for laparotomy comprises an upper clamp rod, a lower clamp rod is sleeved on the lower end of the upper clamp rod, a connecting shaft is inserted and connected to the upper end of the upper clamp rod, the front ends of the upper clamp rod and the lower clamp rod are both inserted and connected to the connecting rod, the front parts of the upper ends of the upper clamp rod and the lower clamp rod are both inserted and connected to the connecting screw, the rear ends of the upper clamp rod and the lower clamp rod are both provided with a net basket, a steel wire is commonly connected between the two net baskets, the rear parts of the opposite ends of the upper clamp rod and the lower clamp rod are both provided with an opening and closing groove, the front ends of the upper clamp rod and the lower clamp rod are both provided with a No. 1 connecting groove, and the rear ends of the upper clamp rod and the lower clamp rod are both provided with a No. 2 connecting groove.

[0006] Preferably, the two No. 2 connecting grooves are respectively connected to the two baskets.

[0007] Preferably, the two connecting screws pass through the upper clamp rod and the lower clamp rod respectively and are interlaced and connected with the two connecting rods.

[0008] Preferably, the connecting shaft passes through the upper clamp rod and is interlacedly connected with the lower clamp rod.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. By setting an upper clamp rod and a lower clamp rod, a net basket is set on each of the upper clamp rod and the lower clamp rod. By pinching the upper clamp rod and the lower clamp rod, the two net baskets are closed, which can better wrap muddy or fragmented stones in open surgery for common bile duct lithotripsy, thereby increasing the success rate of stone removal;

[0011] 2. By arranging connecting rods on both the upper clamp rod and the lower clamp rod, by adjusting the connection lengths between the upper clamp rod and the left connecting rod, and the lower clamp rod and the right connecting rod, and fixing them respectively by connecting screws, the use length of the common bile duct stone removal mesh forceps can be adjusted and fixed, thereby improving flexibility.
