Calculus removing device for department of hepatobiliary surgery

Abstract

The invention relates to the technical field of medical devices, in particular to a calculus removing device for the department of hepatobiliary surgery, which comprises a suction unit and a calculus removing unit, and the suction unit is in through connection with the calculus removing unit through a communicating pipe. The calculus removing unit comprises: a first suction pipe with a closed head end, wherein the tail end of the first suction pipe communicates with the communicating pipe; a plurality of first spiral seams which are uniformly formed in the side wall of the first suction pipe; a second suction tube nested on the outer side of the first suction pipe and in threaded connection with the first suction pipe; a plurality of second spiral seams which are formed in the side wall of the second suction pipe, wherein the distance between every two adjacent second spiral seams is gradually increased. According to the calculus removing device, suction ports with different diameters can be obtained at the same time, and the problem of clogging caused by one suction port is avoided; meanwhile, the size of the suction ports can be adjusted, so that the technical defect that a large amount of blood and tissue fluid are pumped out during suction is overcome, and efficient suction of multiple gallstones at a time is achieved.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, and in particular, there is a stone apparatus for leukold surgery. Background technique [0002] Gold gallstones are a common disease that is proportional to the patient's age. Due to excessive alkali-containing substances in drinking water, the metabolism of the human body cannot be discharged, accumulate forming stones, mainly produced in catheter cavities in the human body or animal, such as kidney, ureter, gallbladder or bladder, etc. The solid blocks formed in the body cavity can cause lumen obstruction, affecting the discharge of the accumulated organ liquid, pain, bleeding or secondary infection; and with the proportion of aging population, gallstone patients The quantity is also growing, for patients with symptoms, if they do not have serious complications, even endanger life. At present, there are mostly invalid, generally need surgery, such as open abdominal teshes, endoscopi...

AI Technical Summary

Problems solved by technology

[0003]The existing stone removal device often uses suction cups to remove stones one by one, and the number of gallstones is often hundreds, so it is not only time-consuming to clean the suction cups one by one, but also harmful to the gallstones. Both the medical staff and the patient’s body are consumed to a certain extent, and cleaning one by one often causes the wound area to increase; the existing technology also uses openings of the same size to remove stones. If the opening is large, it often leads to a large amount of blood and tissue fluid. When the opening is pulled out and the opening is small, the efficiency of stone removal will be reduced due to the blockage of the opening by large stones, which will cause complicated follow-up operations
