Abstract

The invention relates to a hard composite gallbladder endoscope for use in a microtrauma protective gallbladder endoscope lithotomy and polypectomy operation, which comprises a hard mother endoscope and a hard son endoscope, wherein the son endoscope enters a gallbladder lumen through an instrument channel of the mother endoscope. One end and a front end of each of the mother endoscope and the son endoscope adopt a hard endoscope body, wherein the hard mother endoscope comprises the instrument channel, an ocular input end, an endoscope body, a cold light source input end, an endoscope front-end, a hard endoscope end, a water inlet channel, and a water outlet channel; and the hard son endoscope comprises an instrument channel, an ocular input end, a cold light source connector, and a hard endoscope end. The two endoscopes are matched to be used, and the mother endoscope is taken as a platform; when the mother endoscope treats a pathological change of a gallbladder, the son endoscope is easier to enter micro-positions such as a gallbladder neck and a cystic duct and so on, through the instrument channel of the mother endoscope to diagnose and treat and effectively treat smaller calculi and polypi.

Description

Hard child and mother gall bladder endoscope and method

Technical field

The invention belongs to field of medical appliances, be specifically related to a kind of scope guarantor of Wicresoft gallbladder and get stone, get the hard child and mother gall bladder endoscope of polyp operation.

Background technology

At present, the biliary tract scope that gallbladder is got stone, got the polyp operation is protected by the existing Wicresoft that is used for, because structure is simple relatively, fail to find and effectively solve for the clinical setting of more tiny pathological changes such as neck of gallbladder, cystic duct and more complicated, and has only an instrumentation passage, the means that need increase a sheath pipe outside scope are come the real operation of finishing, and the sheath pipe provides operation needed extra instrument channel; In addition because big with the joining ancillary equipment quality of scope, operation inconvenience, scope undergos surgery to cause the doctor to be difficult to correctly fixedly in operation, and the careful position that is not easy to enter gallbladder undergos surgery, thereby has influence on the quality of operation.

Summary of the invention

The objective of the invention is to overcome the deficiency of existing biliary tract scope, a kind of hard child and mother gall bladder endoscope is proposed, two scopes are used, with female mirror is platform, in female mirror diagnosis and treatment gallbladder pathological changes, sub-mirror is by the easier minute sites such as neck of gallbladder and cystic duct that enter of the instrument channel of female mirror, diagnoses and treats, and effectively handle littler calculus, polyp, also can carry out operation of diagnosis and treatment such as cholangiography by ductule.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

A kind of hard child and mother gall bladder endoscope comprises female mirror of hard and the sub-mirror of hard.

The hard shank is adopted in the end of female mirror and sub-mirror and first end.

The female mirror of hard comprises instrument channel, eyepiece input, scope main body, cold light source input, scope front end, hard scope end, intake tunnel and exhalant canal; The sub-mirror of hard comprises instrument channel, eyepiece input, cold light source joint, hard scope end.The sub-mirror outer end diameter of described hard is 2.0～2.6mm, and length is 400～500mm, and the diameter of instrument channel is 0.8～1.0mm, optical lens diameter 1.0～1.9mm.The female mirror instrument channel of described hard is provided with sealing device and prevents that liquid return is to main body.The connected mode of hard child and mother gall bladder endoscope is the external cold light source of the female mirror of described hard, the external xenon cold light source of the external cold light source joint of the sub-mirror of hard main frame, the external image system of the female mirror of hard, the external image system eyepiece input of the sub-mirror of hard connect hard child and mother gall bladder endoscope Flame Image Process center, external at least 1 monitor of the interface of monitor at hard child and mother gall bladder endoscope Flame Image Process center.

A kind of using method of hard child and mother gall bladder endoscope, with the female mirror of hard is platform, the sub-mirror of hard is through the instrument channel of the female mirror of hard, miniature incision enters the gallbladder intracavity through the gallbladder bottom, utilize its independently instrument channel find and handle the pathological changes at neck of gallbladder, the thin position of cystic duct, also can carry out the cholangiography operation of diagnosis and treatment by ductule.

Compared with prior art, the beneficial effects of the utility model are:

Make Wicresoft protect gallbladder and get stone, get that the polyp operation is more thorough, safety coefficient is higher, also the research for the gallbladder pathological changes provides reliable platform, gets stone and performs the operation and push to develop in depth and breadth protecting gallbladder.
