Sand-like gall bladder calculus suction system

Abstract

The invention belongs to the field of medical instruments, and particularly discloses a sand-like gall bladder calculus suction system. The system comprises a hard gall bladder mirror, wherein the hard gall bladder mirror comprises an endoscope main body, a hard endoscope end part, a water inflow channel or / and a water outflow channel; a sand-like calculus absorption box made of a flexible material is sleeved on the tip part of the front end of the hard endoscope end part, and is a through pipe which is provided with a large diameter end for collecting sand-like calculuses and a small diameter end connected with the tip part; and the water inflow channel or / and the water outflow channel are connected with a negative pressure suction device. In the system, the sand-like calculuses in a gall bladder cavity are sucked completely by a principle similar to that of a vacuum dust collector. Due to the design of a sand-like gall bladder calculus suction box, surgery methods such as pushing, extrusion, pressing and the like of a doctor and the accommodation of the sand-like calculuses are facilitated. The system is manufactured by a silica gel material with appropriate hardness, so that the operation experience degree of the doctor is realized to the greatest extent, damages to the wall of a gall bladder are reduced to the lowest extent, and protection for the gall bladder of a patient and improvement on the safety of a surgery are facilitated.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a suction system for gallbladder sediment-like stones. Background technique [0002] At present, endoscopic minimally invasive surgery is widely used in medical treatment, especially in gallbladder stone removal surgery. After the rigid cholecystoscope enters the gallbladder, the doctor can process the stones in the gallbladder cavity through the clear image of the monitor. The sediment-like stones or gallbladder intramural stones that may be found in the gallbladder, it is very difficult to use rigid cholecystoscope, mesh basket and external negative pressure suction machine to solve the problem completely. A proper tool can clean up thoroughly; on the other hand, due to the high hardness of the hard end of the rigid cholecystoscope, the gallbladder mucosa may be damaged or even punctured during the operation. Although there is also a suction system for gallbladder se...

Problems solved by technology

[0002] At present, endoscopic minimally invasive surgery is widely used in medical treatment, especially in gallbladder stone removal surgery. After the rigid cholecystoscope enters the gallbladder, the doctor can process the stones in the gallbladder cavity through the clear image of the monitor. The sediment-like stones or gallbladder intramural stones that may be found in the gallbladder, it is very difficult to completely solve the problem by using rigid cholecystoscope, mesh basket and external negative pressure suction machine. A proper tool can clean up thoroughly; on the other hand, due to the high hardness of the hard end of the rigid cholecystoscope, it may cause damage to the gallbladder mucosa during operation, and even puncture the gallbladder mucosa

Although there is also a suction system for gallbladder sediment-like stones at present, its use method is to use the structure to fix the tip of the rigid cholecystoscope, so as to buffer the hard tip of the gallbladder mucosa when tearing and punching. Injury, although this gallbladder sediment-like stone suction system has a certain effect on preventing gallbladder mucosal damage, but because the hardness is still too hard, it still often damages the gallbladder mucosa and affects the quality of surgery

[0003] The silt-like stones are small in size, with a diameter of about 1mm, like broken sand on a river beach, while the gallbladder wall is generally concave-convex, and the silt-like stones are like fine sand sprinkled on a carpet. Difficult to remove by existing conventional methods
