Abstract

The utility model discloses an oral-nasal catheter extraction device, which belongs to the tongue depressors or surgery instruments. The oral-nasal catheter extraction device comprises a handle with one circular end at one end and a circular end tongue depressing part at the other end; a tongue depressor is entirely bent to form a reversed arc; guide wire passages with two opened ends are correspondingly formed on two sides of the tongue depressor, and guide wires respectively penetrating through a front hole form a collar in front of the tongue depressing part, and a guide wire penetrating out of a rear hole is fixedly connected with the collar into a whole. With the design in the utility model, the time for operation on patients in narcosis is not required to be lengthened, nasal biliary and nasal pancreas drainage tubes can be easily extracted without causing pains on patients; the injury caused by a surgeon on all tissues on the throat wall of patients is avoided, the possibility of haemorrhage is reduced, patients are safe, the operation success rate is high, and the operation is convenient and is simple and easy to learn. Through the use on 1000 patients, the oral-nasal catheter extraction device obtains highly satisfactory practical effect.

Description

Mouth and nose conduit taking equipment

Technical field

This utility model relates to glossocatochus tool or surgical instruments, specifically is a kind of mouth and nose conduit taking equipment.

Background technology

Antidromicity gallbladder pancreatic ductography (ERCP) technology is widely used in micro-wound surgical operation, its many gallbladder pancreas systemic disease of not only can clarifying a diagnosis, can also carry out the treatment of gallbladder pancreas systemic disease, nose gallbladder (pancreas) drainage is an art formula necessary after these disease treatments.Therefore, each carries out the patient of duodenoscope treatment, and great majority all need to place nose gallbladder (pancreas) drainage tube (being called for short the BD pipe).

During operation, the last lower teeth of patient is bitten the choma bite-block, places nose gallbladder (pancreas) drainage tube through duodenoscope, takes out duodenoscope, keeps somewhere nose gallbladder (pancreas) drainage tube, and nose gallbladder (pancreas) drainage tube outer end is dragged outside the oral cavity; Other is inserted to nose conduit insertion end via intranasal application pharyngeal, and keep somewhere outside the nasal cavity outer end; Patient's finger stretches into the oral cavity, and from the pharyngeal nose conduit insertion end that plucks out to the oral cavity, again nose conduit insertion end is docked with nose gallbladder (pancreas) drainage tube outer end, and it is pharyngeal to give up the throne, last, haul out complete nose conduit from nasal cavity, and nose gallbladder (pancreas) the drainage tube outer end of docking with it, abandon the nose conduit, realize nose gallbladder (pancreas) drainage tube via intranasal application is kept somewhere in vivo, and nose gallbladder (pancreas) drainage tube outer end places outside the nasal cavity, the fixing reservation.

In order to alleviate patient's misery, at present, adopt under the narcotism treated more, still, the following problem of the thing followed also occurred: not clear-headed patient after the anesthesia, when still not possessing mating capability, nose gallbladder (pancreas) drainage tube can not be smoothly be changed its course by the oral cavity derives from nasal cavity, traces it to its cause, and 1. patient can not cooperate with on one's own initiative and stretches out tongue under the narcotism, tissues such as root of the tongue portion and uvula, tonsil press together in addition, and the difficulty that the nose conduit is drawn strengthens; 2. generally, the patient takes the nose conduit with finger, not only easily patient is damaged, and the patient also has the danger of being bitten by not wide-awake patient; 3. meet fat or during patient that head is bigger, patient's finger length is not enough, causes operation failure, and has to prolong operating time, or waits for that the clear-headed back of patient reuse sponge holding forceps under lighting condition, takes out the nose conduit.

Summary of the invention

This utility model is exactly the problem of taking out nose conduit degree of difficulty in order to solve under narcotism, and a kind of mouth and nose conduit taking equipment of handled easily is provided.

This utility model is realized by following technical scheme.

A kind of mouth and nose conduit taking equipment, comprise that an end is the handle of button-head, the other end is that button-head is pressed tongue, and the whole curved spatula of opposite arc that forms, and be formed with the two ends silk guide passage of opening respectively in spatula dual-side correspondence, the seal wire that penetrates through prosopyle is pressing tongue the place ahead to form the collar respectively, and fixed through the seal wire termination that deutostoma passes is one.

She Ji this utility model need not prolong operating time under patient's narcotism like this, nose gallbladder (pancreas) drainage tube can be derived patient's no pain easily; Avoid the damage of patient, reduce hemorrhage probability each tissue of patient's throat wall; Patient's safety, the success rate of operation height, easy to operate, easy to learn.Through 1000 many cases patients are used, obtained very satisfied practical function.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is elaborated.

A kind of mouth and nose conduit taking equipment, comprise that an end is the handle 1 of button-head, the other end is that button-head is pressed tongue 2, and the whole curved spatula 3 of opposite arc that forms, and be formed with the two ends silk guide passage 4 of opening respectively in spatula 3 dual-side correspondences, the seal wire 6 that penetrates through

prosopyle

5a, 5b is pressing tongue 2 the place aheads to form the collar 7 respectively, and fixed through seal wire 6 terminations that

deutostoma

8a, 8b pass is one.Seal wire 6 two ends that pass from

deutostoma

8a, 8b adopt plastics or metal snap close 9 to become one respectively, prevent to separate to deviate from.

Described mouth and nose conduit taking equipment, its silk guide passage 4 is conformal bendings with spatula 3, the whole curved spatula 3 of opposite arc that forms is convenient to fully expose and show pharyngeal through pressing the tongue 2 compressing roots of the tongue.

Described mouth and nose conduit taking equipment, its seal wire 6 is the stainless steel silks with certain intensity and toughness.

Described mouth and nose conduit taking equipment, the silk guide passage 4 of its spatula 3 and both sides thereof is integrally formed.
