Abstract

The utility model relates to a nasobiliary tract tractor, which belongs to medical equipment. The handle is hollow inside, with a chute on the surface and an opening at the front end. The buckle is located inside the handle and is slidably connected with the chute of the handle. The silicone tube is sleeved outside the nickel-magnesium alloy wire. The two ends of the wire are fixedly connected with the buckle, the nickel-magnesium alloy wire covered with the silicone tube is located in the handle and passes through the hole at the front end of the handle, and the protruding part forms a ring. The advantage is that the structure is novel. Through clinical practice in recent years, it has been used in thousands of operations and achieved complete success. The transposition operation is safe, accurate, quick and convenient. Transposition operation time has been shortened from 5 minutes to 1 minute. Since the operation time is saved, it is very beneficial to save the life of the patient, and the postoperative pain of the patient is significantly reduced. The surgeon and anesthetist are very welcome.

Description

Nose bile duct traction apparatus

Technical field

This utility model belongs to medical apparatus and instruments, refers in particular to for performing the operation through endoscopic retrograde ERCP.

Background technology

One is had to perform the operation through endoscopic retrograde ERCP at present clinically, this operation is made up of multinomial technical operation, wherein one is called nasobiliary drainage (ENBD), also the technology that nose bile duct replaces can be, technical operation is passed through exactly by being placed in intraoral drain nose bile duct in operation, being transformed into nasal cavity, thus being reached through the object of nasal cavity bile drainage or extract, is the important component part of this operation.

At present, nose bile duct moves on to nasal cavity from oral cavity be lean on nurse by sponge holding forceps or directly use finger manipulation, and concrete operating process is:

1) insert pharynx rear wall by red rubber catheter via intranasal application, outside nasal cavity, leave 8 centimetres;

2) find and pinch red rubber catheter with the seal wire crossed at pharynx rear wall with in finger or sponge holding forceps or art;

3) nose bile duct end in oral cavity is inserted in the duct of yellow jacket glue catheter head, pull red sebific duct, nose bile duct is moved to nasal cavity from oral cavity.

As can be seen from aforesaid operations scheme, because not having special apparatus, the shortcoming that such scheme exists is:

1) use sponge holding forceps processing ease to press from both sides pendency tongue injury is pharyngeal, tongue, tooth by mistake;

2), when ticking red rubber catheter with the finger of band sterile gloves, operator is easily hurt as patient oral cavity, short owing to pointing, seek hook sebific duct very difficult, extend operating time;

3) also waste time and energy very much with in art, seal wire operation is both dangerous, unhygienic.

Because above three shortcomings can accidentally injure other organs, the operating time is long again, therefore once repeatedly occurs in art unexpected, as inhaled by mistake, and the situations such as sudden cardiac arrest.

Summary of the invention

This utility model provides a kind of nose bile duct traction apparatus, and other organs are accidentally injured in the meeting existed during to solve and nose bile duct to be moved on to nasal cavity from oral cavity, and the operating time is long, easily occurs unexpected problem in art.

The technical scheme that this utility model is taked is: handle inner hollow, surface have chute, there is perforate front end, buckle is positioned at this handle inner and is connected with the slide of handle, it is outside that silica gel tube is socketed in nickel magnesium alloy wire, this cover has the nickel magnesium alloy wire two ends of silica gel tube to be fixedly connected with this buckle, and this cover has the nickel magnesium alloy wire of silica gel tube to be positioned at this handle and to pass from the hole of handle front end and this extension forms an annular.

A kind of embodiment of this utility model is the long 17-20 centimetre of handle.

A kind of embodiment of this utility model has anti-slip veins outside handle.

A kind of embodiment of this utility model is that cover has the nickel magnesium alloy conductor length of silica gel tube to be 30-40 centimetre.

The utility model has the advantages that novel structure, by clinical practice in recent years, use in thousands of example operation, obtain success completely.Make ex-situ operations not only safe, accurate, quick but also very convenient.The ex-situ operations time from before 5 minutes shorten to 1 minute.Owing to saving operating time, very favourable to the life saving patient, the misery after operation in patients obviously alleviates, and patient, anaesthetist welcome very much.

Detailed description of the invention

Handle 3 inner hollow, surface have chute 301, there is perforate front end, buckle 4 is positioned at this handle inner and is connected with the slide of handle 3, it is outside that silica gel tube 2 is socketed in nickel magnesium alloy wire 1, this cover has the nickel magnesium alloy wire two ends of silica gel tube to be fixedly connected with this buckle, and this cover has the nickel magnesium alloy wire of silica gel tube to be positioned at this handle and to pass from the hole of handle front end and this extension forms an annular.

A kind of embodiment of this utility model has anti-slip veins 302 outside handle.

Using method of the present utility model:

The first step, hold handle, put this utility model into oral cavity gently, push away forward buckle, to allow the head of wire ring portion arrive at pharyngeal;

Second step, red rubber catheter via intranasal application to be inserted to pharynx rear wall, allow its termination put in this conductor loop, red rubber catheter will leave 8 centimetres outside nasal cavity;

3rd step, slide backward buckle, make conductor loop entangle yellow jacket glue catheter proximal end, pull out this utility model gently, key is in company with the red rubber catheter of pull-out, takes off conductor loop;

4th step, nose bile duct end in oral cavity is inserted in the duct of this yellow jacket glue catheter head;

5th step, gently draw the outer red rubber catheter of nasal cavity, take nose bile duct out of, complete nose bile duct place-exchange.
