Abstract

The utility model relates to an integrated three-passage cystic endoscope, which comprises an apparatus passage, an input end of an eye lens, an endoscope body, an input end of a cold light source, an endoscope front end, an endoscope end part, a water inlet passage and a water outlet passage. The water inlet passage and the water outlet passage are directly introduced to the endoscope body and are formed integrally with the endoscope front end and the endoscope end part. The apparatus passage, the water inlet passage and the water outlet passage, an optical fiber and an optical lens are integrated in the endoscope body, the endoscope front end and the endoscope end part, and a liquid double-passage can be used as an increased apparatus passage, which is convenient for thinner apparatuses to enter. The humanized design of the integrated three-passage cystic endoscope is more suitable to be used by a doctor, so that the use range of the operation is expanded greatly, and safety and convenience of the operation are improved.

Description

Integrated triple-channel vesicula fellis endoscope

Technical field

This utility model belongs to field of medical appliances, relates to modern medicine and carries out new-type scope Wicresoft and protect a kind of core medical instrument that gallbladder is got stone, got the 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 volume is less, structure is thin, and has only an operating walk way, for the clinical setting of more complicated, single instrument channel can not be finished operation smoothly effectively, needs the extra instrument channel that increases.Present method is that the means that increase a sheath pipe outside scope realize, the sheath pipe provides operation needed extra instrument channel; Because big with the joining ancillary equipment quality of scope, operation is inconvenient in addition, and scope undergos surgery to cause the doctor to be difficult to correctly fixedly in operation, thereby has influence on the quality of operation.

Get stone at guarantor's gallbladder, get in the polyp operation,, in the operation, need reserve the distance of 150mm so that carry out operation efficiently, but the size of existing biliary tract scope can not satisfy the requirement of above-mentioned operation on gallbladder if the length of gallbladder is 100mm approximately.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of existing biliary tract scope, proposes a kind of guarantor's gallbladder that is applicable to more and gets stone, gets the integrated triple-channel vesicula fellis endoscope that the polyp operation is more thorough, safety coefficient is higher.

This utility model is realized in the following manner:

This utility model integrated triple-channel vesicula fellis endoscope, comprise instrument channel, eyepiece input, scope main body, cold light source input, scope front end, scope end, intake tunnel and exhalant canal, its intake tunnel and exhalant canal directly feed scope main body and scope front end, the scope end is integrally formed.

Above-mentioned eyepiece input becomes the angle of 135 degree with the scope axis.

Above-mentioned intake tunnel becomes 30 degree to stretch out to scope main body both sides respectively with the exhalant canal input with the scope axis.

Above-mentioned scope end optimum diameter is 5.4mm, wall thickness 0.1mm, and length is 253mm; Endoscopic instruments passage optimum diameter 1.9mm; The input optimum diameter of scope optical lens is 2.8mm.

Above-mentioned scope elder generation end is equipped with the mucous membrane of gallbladder guard box, and its mucous membrane of gallbladder guard box can be tubular structure, also can be horn-like structure, but is not limited to this two kinds of structures.

This utility model integrated triple-channel vesicula fellis endoscope, its scope main body has been concentrated instrument channel, intake tunnel and exhalant canal, cold light source input and light path input, the scope end is integrated integratedly instrument channel, biliquid passage and optical system.

Instrument channel of the present utility model is provided with sealing device and prevents that liquid return is to main body.

This utility model integrated triple-channel vesicula fellis endoscope becomes 60 ° between its intake tunnel and the exhalant canal, and each fluid passage becomes 30 ° with the centrage of scope, its diameter 0.9mm, can be used as the instrument channel of increase, enter, increase the operation multiformity as thinner apparatus.

This utility model integrated triple-channel vesicula fellis endoscope, its cold light source input is vertical with the centrage of scope.

This utility model integrated triple-channel vesicula fellis endoscope, its light path input becomes 135 ° with the centrage of scope, and light path adopts the 2.8mm optical system.

This utility model integrated triple-channel vesicula fellis endoscope; the human body input optimum diameter of its gall bladder endoscope is 5.4mm; wall thickness 0.1mm; endoscopic instruments passage optimum size is at 1.9mm; the optimum diameter of scope optical lens is 2.8mm; scope end optimum length is 253mm; scope elder generation end can put the mucous membrane of gallbladder guard box according to surgery situation; this mucous membrane of gallbladder guard box can adopt tubulose and horn-like form; also can adopt other form; the mucous membrane of gallbladder guard box is nontoxic transparent or semitransparent elastomeric material, thickness 1mm.

This utility model also improves the size that the biliary tract scope enters the end of human body, the diameter of the diameter of elder generation end, the diameter of instrument channel, optical lens is more meticulousr than present scope, the less relatively biliary tract scope end of size can enter the finer position of human body in operation, observe situation about in the past not being observed, littler calculus, polyp are obtained completely, find and effectively handle calculus under the mucous membrane of gallbladder, improve the quality of medical treatment greatly.

This utility model greatly enlarges the scope of application of operation, has improved the operation safety coefficient.
