Problems solved by technology

In the past, laparoscopic cholecystectomy was often used. In recent years, with the re-understanding of gallbladder function, minimally invasive gallbladder stone (polyp) surgery has been favored by general surgeons and gallbladder stone (polyp) patients. The cholecystoscope is put into the gallbladder through the gallbladder incision, and the stones are removed through the stone basket. Because the incision is difficult to fix, the gallbladder needs to be pulled repeatedly during the operation, especially when multiple stones (polyps) need to be repeatedly entered and exited. The operation is time-consuming and difficult to remove stones And it is very easy to cause damage to the gallbladder and gallbladder mucosa, or it is difficult to remove stones (polyps), and when the gallbladder is inflamed, the bile is cloudy and viscous, resulting in blurred vision and difficult operation

Abstract

The invention relates to the technical field of medical auxiliary instruments, in particular to a gallbladder preserving and calculus removing operation sheath tube. The operation sheath tube comprises a sheath tube body and a sheath core arranged in the sheath tube body in a sleeved mode, wherein the outer side wall of the sheath tube body is provided with scales and scales values, the scales comprise the long scales and the short scales, four short scales are arranged between every two adjacent long scales, the distance between every two adjacent long scales is 0.5 cm, the distance between every two adjacent short scales is 0.1 cm, the scale values are arranged on one side of the long scales, and the scale values are arranged from the front end of the sheath tube body at the interval of two long scales. The operation sheath tube is simple in structure, economical, practical and capable of keeping a gallbladder operating channel open all the time, reducing the complication of injuries of the gallbladder and gallbladder mucosae and shortening operation time, a gallbladder cavity can be washed with water in time, and the operative field can be conveniently exposed for an operator.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a gallbladder-preserving and stone-removing operation sheath. Background technique [0002] Gallstones\gallbladder polyps are common and frequently-occurring diseases in general surgery. In the past, laparoscopic cholecystectomy was often used.
