Ligation clip continuous shooting clip applier and use method thereof

Abstract

The invention provides a ligation clip continuous shooting clip applier and a using method thereof. The ligation clip continuous shooting clip applier comprises a gun body assembly used for holding and shooting and composed of a left shell, a right shell, a clip feeding assembly, a shooting assembly and a clip bin loading and unloading button, a gun barrel assembly is movably installed at one end of the gun body assembly, an upper connecting pipe and a lower connecting pipe are connected by buckles, an annular cavity structure formed by an upper shooting connecting ring and a lower shooting connecting ring is movably arranged on the outer side of the upper connecting pipe and the outer side of the lower connecting pipe in a sleeving mode and axially moves outside the upper connecting pipe and the lower connecting pipe, and barbs are arranged at the front end of a pushing clamping plate and the front end of a clamping storage groove; and the ligation clip continuous shooting clip applier further comprises a clip bin assembly used for loading and unloading the ligation clip, the clip bin assembly can be replaced, the ligation clip can be quickly supplemented after being used up in the operation process, the clip applying time is shortened, meanwhile, the ligation clip is basically in a natural state in the clip bin assembly, the failure rate of the ligation clip is greatly reduced, and the gun body assembly and the gun barrel assembly can be repeatedly used in the same operation, so that the economic burden of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ligation clip continuous clip applicator and a method for using the same. Background technique [0002] During laparoscopic surgery, it is necessary to ligate the blood vessels of the severed organs and tissues to stop bleeding. A common method is to use ligation clips to ligate the blood vessels to block the blood flow. [0003] At present, there are two kinds of clip appliers used for ligation clips, one is single-shot clip applier, and after a ligation clip is installed on the jaws of single-shot clip applier, the surgeon will extend the clip applier into the patient's abdominal cavity to complete the procedure. Apply the clip, then take the clip applier out of the patient's abdominal cavity, pass it to the nurse to complete the installation of the new ligation clip, and then pass it to the surgeon, who then re-inserts the clip applier into the patient's abdominal ca...

Problems solved by technology

[0003] At present, there are two kinds of clip appliers used for ligation clips, one is single-shot clip applier, and after a ligation clip is installed on the jaws of single-shot clip applier, the surgeon will extend the clip applier into the patient's abdominal cavity to complete the procedure. Apply the clip, then take the clip applier out of the patient's abdominal cavity, pass it to the nurse to complete the installation of the new ligation clip, and then pass it to the surgeon, who then re-inserts the clip applier into the patient's abdominal cavity to complete the clip application, and so on Every time one or several ligation clips are completed to ligate blood vessels, a more complicated process is required, which not only prolongs the operation time, but also increases the multiple injuries caused by the repeated entry and exit of instruments into and out of the patient's abdominal cavity, and also increases the bleeding of the patient during the operation. quantity

[0004] The other is a clip applicator that fires multiple ligature clips at once. This kind of clip applier is loaded with 10-20 ligature clips inside the barrel. These ligature clips can be used continuously, although this clip The pliers solve many problems in the use of single-shot clamps, but there are still two shortcomings. First, the ligature clip is in a closed state for a long time in the barrel, and the ligature clip is prone to plastic deformation. When the ligature clip is pushed to the clamp When opening the mouth, it often cannot be fully bounced, causing the ligature clip to fall from the jaws and cannot complete the clip application smoothly; second: when the number of ligature clips in the clip applicator barrel cannot meet the needs of the operation, it is necessary to replace the new clip applier , because the ligation clip cannot be reloaded, which obviously increases the economic burden of the patient, the existing application number is "CN202011563231. sending method
