Description
Technical field
This utility model relates to medical operating apparatus field, is specifically related to digestive endoscopy surgical apparatus, and particularly a kind of percutaneous inserts auxiliary sheath through stomach common bile duct scope.
Background technology
Digestive endoscopy operation is a new technique of rising in recent years, its method be soft scope direct oral cavity or percutaneous in stomach penetrates human body, the internal organs that arrival need to be spied on carry out pathological changes observation, diagnosis and the operative treatment of organ disease in perfect aspect.The advantage of endoscopic surgery is without pain etc. after good effect, Wicresoft, operation in patients.Endoscopic technic application is at present more and more extensive.
In the time carrying out common bile duct medical diagnosis on disease and treatment, scope need to be inserted into common bile duct and carry out lesion examining.In the prior art, have two kinds of modes for common bile duct endoscopy, first method be per os insertion, scope along oral cavity, esophagus, Stomach duodenum approach insert, and finally arrives common bile duct.This mode shortcoming is that the distance of scope insertion process is longer, after scope inserts, in gastric lopping, inserts mirror strength and is difficult to be delivered to scope front end, causes scope to be inserted into choledoch-success rate not high.Second method be percutaneous through stomach insertion, scope, through skin incision, Stomach duodenum, finally arrives common bile duct.The advantage of the relative first kind of way of this mode is to insert mirror apart from shorter, is inserted into common bile duct but scope also can affect scope in gastric lopping after inserting.
The existing inventor, for overcoming the above problems, develops a kind of auxiliary sheath that scope inserts of being convenient to, and it is simple to operation, can accurately locate, and easily scope is directed to common bile duct.
Utility model content
The purpose of this utility model is to solve above defect, provides a kind of percutaneous to insert auxiliary sheath through stomach common bile duct scope, is mainly used in the pathological changes of endoscope observation common bile duct inside, and it is simple to operation, can accurately locate, and easily scope is directed to common bile duct.
The purpose of this utility model is achieved in the following ways:
Percutaneous inserts auxiliary sheath through stomach common bile duct scope, be mainly used in endoscope and observe the pathological changes of common bile duct inside, its structure comprises for percutaneous inserts and extends to choledoch-sheath tube body through stomach, the tubular structure that this sheath tube body is hollow, sheath tube body diameter is preferably 8～12mm, length is preferably 35～45cm, except above preferred size, can also be designed to other specification.The head end of sheath tube body is provided with Handheld Division, hand-held holding when Handheld Division is used for performing the operation, convenient operation.The top of Handheld Division is provided with the opening for inserting scope, and the tail end of sheath tube body is connected with and the integrated coil of sheath tube body, and coil can freely turn round, and is convenient to penetrate duodenal turning round.Scope inserts from the opening of top, Handheld Division, the coil from sheath tube body tail end again after sheath tube body, then enter common bile duct, on the pipe shaft of coil, be provided with the positioning wire for limiting coil steering position, because coil can freely turn round, after the shape that coil turns round is determined, need to carry out position restriction to coil, be therefore designed with positioning wire.One end of positioning wire is fixed on coil afterbody, its other end extends to the head end of sheath tube body movably through the pipe shaft of sheath tube body, and extend outward one section for stretching and the steel wire operating side of fixing coil steering position from the head end of sheath tube body, on this steel wire operating side, comprise the sincere parts of folder for tightening up positioning wire.Positioning wire can stretch in activity in sheath tube body, thereby limits the shape of turning round of coil.
As preferably, between the outer wall of described coil and sheath tube body and inwall, be provided with the cinclides for penetrating positioning wire, positioning wire is arranged in cinclides movably.
As preferably, the sincere parts of described folder are clamped-in style snap close.
As preferably, the sincere parts of described folder are fast-holding pincers.
As preferably, the sincere parts of described folder are for clamping switch knob.
As preferably, described Handheld Division is cylindrical.
In addition, except above structure, press from both sides sincere parts and can also be set to other structure, object is clamping and positioning steel wire, makes to guarantee the shape invariance that turns round of coil behind its location.
As preferably, described steel wire operating side is located at the front of Handheld Division, and positioning wire extends to the sincere parts of folder movably toward its front through the inside of Handheld Division.
As preferably, described steel wire operating side is located at the rear of Handheld Division, and positioning wire extends to the sincere parts of folder along the head end of sheath tube body toward its outer surface movably.
As preferably, described Handheld Division and the sheath tube body structure that is formed in one.
The beneficial effect that this utility model produces is: novel auxiliary sheath, being mainly used in endoscope percutaneous inserts through stomach, and scope is directed to common bile duct, thereby by endoscopic diagnosis and treatment common bile duct disease, compared with traditional product, this patent product operation is simple and convenient, the coil of setting up makes its afterbody can freely turn to the bending of adaptation duodenum, thereby be inserted into common bile duct after making scope be easy to arrive descendant duodenum, improve scope and insert choledoch-success rate, and treat the efficiency of common bile duct disease by endoscopic diagnosis.
