Abstract
The invention relates to a three-channel biliary endoscope, which is a core medical device used in the operations of endoscopic minimally invasive lithotomy in protect gallbladder and removing polypus, comprising a biliary endoscope and an external sheath tube by the design of which two channel for inserting operation devices is added. The three-channel biliary endoscope has the advantages that: at most three operation devices can be used during the operation of removing stones in protect gallbladder and take polypus, thus, the application range of the operation is enlarged and the safety and convenience of the operation is enhanced; the terminal length of the biliary endoscope is shortened, the diameter of the forefront part of the three-channel biliary endoscope is more precise than the diameter of the prior endoscope, thus, the operation of removing stones in protect gallbladder and taking polypus can be finished better and the quality of the operation is enhanced.
Description
Technical field
The invention belongs to field of medical appliances, relate to modern medicine and carry out new-type scope Wicresoft and protect a kind of core medical instrument that gallbladder is got stone, got the polyp operation.
Prior art
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, has only an operating walk way, and 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.
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 fails to satisfy above-mentioned requirements if the length of gallbladder is 100mm approximately.
Hospital finds in a large amount of operation cases, for the special circumstances of getting at guarantor's gallbladder in the stone operation, be shaped or some drift things greater than cystic polyp, the intracavity gallbladder of 1.5mm as calculus, diameter under the mucous membrane of gallbladder, utilize existing single channel biliary tract scope to be difficult to the processing that undergos surgery effectively.Based on this problem, A designer person has proposed the structural design of dual pathways biliary tract scope, it is at the external sheath pipe of human body input, purpose increases a mechanical passage, promptly increase an operation path, this improved biliary tract scope structure has been done improvement to a certain degree to the problems referred to above, makes operation increase safety, effectiveness, has improved the medical safety quality that gallbladder is got stone, got the polyp operation.But, this improved dual pathways biliary tract scope is not realized full effective surgery processing yet fully, be shaped or some too much drift things for too much cystic polyp, intracavity gallbladder, utilize existing single channel or dual pathways biliary tract scope all can't solve the problem of bringing in the operation fully, thoroughly, better.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing single channel or dual pathways biliary tract scope, propose a kind of guarantor's gallbladder that is applicable to more and get stone, get the triple-channel endoscope for biliary tract that the polyp operation is more thorough, safety coefficient is higher.
The present invention realizes in the following manner:
A kind of triple-channel endoscope for biliary tract, comprise the biliary tract scope, the biliary tract scope comprises input, endoscopic cold light source input and the human body input of scope machinery passage, scope water inlet and exhalant canal, scope optical lens, its human body input at the biliary tract scope fixedly is nested with an external sheath pipe, and external sheath pipe is provided with human body input passage and two mechanical passages of biliary tract scope.
Described triple-channel endoscope for biliary tract, two mechanical passage inputs of its external sheath pipe are spent to being 45 with external sheath caliber respectively.
Form the angle of 90 degree between described two mechanical passages.
Described triple-channel endoscope for biliary tract, its external sheath pipe is by being connected with the connecting axle of elastic snap ring with the biliary tract scope.
Described triple-channel endoscope for biliary tract, the human body input optimum diameter of its biliary tract scope is 3.2mm, wall thickness 0.15mm, and scope machinery passage optimum size is between 2.9mm and 1.8mm, the input optimum diameter of scope optical lens is 1mm, and human body input optimum length is 280mm.
Described triple-channel endoscope for biliary tract, it is circular that the end that enters human body of its external sheath pipe is designed to non-rule, its maximum outside diameter is set to 6.5mm, the tip lengths that enters human body is set to 250mm, admission passage and two mechanical passages of a biliary tract scope are set, biliary tract scope channel diameter 3.5mm and mechanical passage (operation technique passage) diameter 2mm.
The present invention is provided with external sheath pipe on existing biliary tract scope, its biliary tract scope is consistent with traditional structure, and its external sheath pipe is a device that is fixed on biliary tract scope human body input; Itself and twin-channel biliary tract scope difference are that its external sheath pipe provides two mechanical passages, combine with the mechanical passage of biliary tract scope self, three operation technique passages can be provided, be shaped or too much drift thing for too much cystic polyp, intracavity gallbladder, utilize triple-channel endoscope for biliary tract can solve the problem of bringing in the operation fully, thoroughly, better, thereby the more complicated guarantor's gallbladder of realization is got stone, is got the polyp operation.
The mechanical passage input of external sheath pipe is 45 degree with the best radially; Article two, the best is an angle of 90 degrees between the mechanical passage, and purpose makes things convenient for entering flexibly of operating theater instruments.
External sheath pipe connects simply, stablizes by being connected with the connecting axle of elastic snap ring with novel biliary tract scope, helps undergoing surgery reliably.In fact its syndeton can adopt multi-form syndeton, is not limited to this mode.
The present invention has shortened the length that enters people's end of body, owing to shortened effective length, thus increased the stability of scope in the operation, help protecting the carrying out that gallbladder is got stone, got the polyp operation more, improve the medical safety quality.
The present invention 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 mechanical passage, 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.
Biliary tract scope of the present invention is divided into a series of specification according to the angle of optical lens, is respectively 0 degree mirror, 30 degree mirrors, 70 degree mirrors.Abundant biliary tract scope series can be selected suitable scope according to patient's operation different situations for the doctor.
The present invention greatly enlarges the scope of application of operation, has improved the operation safety coefficient.
