Abstract

The utility model discloses percutaneous tracheotomy dilating forceps which are formed in the mode that a left forcep arm and a right forcep arm are hinged through a hinge pin. The rear end of the left forcep arm and the rear end of the right forcep arm are respectively provided with a handholding ring. A left forcep arm elbow is arranged at the front end of the left forcep arm, a right forcep arm elbow is arranged at the front end of the right forcep arm, the left forcep arm elbow rotates around the hinge pin to be attached to the right forcep arm elbow, the opposite inner lateral sides of the left forcep arm elbow and the right forcep arm elbow are respectively provided with a line guiding groove, and the two line guiding grooves are matched with each other. A left forcep buckling rack and a right forcep buckling rack which are opposite and can be buckled are arranged at the junction between the left forcep arm and the corresponding handholding ring and the junction between the right forcep arm and the corresponding handholding ring respectively, a scale strip is arranged on the left forcep buckling rack and located in the length direction of the end face, in contact with the right forcep buckling rack, of the left forcep buckling rack, and the width of the left forcep buckling rack is larger than that of the right forcep buckling rack. The percutaneous tracheotomy dilating forceps have the advantages that dilating is accurate, time and labor are saved, operation can be achieved with one hand, the problem that a trachea incision is overlarge due to overlarge exerted force is effectively solved, an operation view is clearly exposed, and an operation is easily carried out.

Description

A kind of percutaneous tracheotomy stretching pliers

Technical field

This utility model relates to medical device technical field, relates in particular to a kind of percutaneous tracheotomy stretching pliers.

Background technology

Usually running into clinically tracheotomy stretching pliers expansion excessive tissue, to make tracheal casing pipe insert rear space more, or the expansion of tracheotomy stretching pliers organizes deficiency that tracheal casing pipe can not be inserted smoothly, situation about need repeatedly expand.And tracheal casing pipe model is from adult to child, according to internal diameter size, be divided into multiple cast, need different degrees of expansion, while using opening clamp expansion trachea, need with hands, fix with patient, according to tracheal diameter, control the expansion dynamics of stretching pliers; But the time has been grown arm and can produce fatigue, be easy to make the trachea displacement strutting; Have part stretching pliers because being firmly reverse to need bimanualness to strut tong arm just to realize expansion, because one hand cannot operate, how hands easily causes surgical field of view unintelligible simultaneously.

Utility model content

The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of percutaneous tracheotomy stretching pliers of predeterminable expansion width is provided.

For realizing above object, this utility model has been taked following technical scheme: a kind of percutaneous tracheotomy stretching pliers, the left clamp arm and the right clamp arm that by rear end, are respectively equipped with the circle of shaking hands form by bearing pin is hinged, left clamp arm front end is provided with left clamp arm elbow, right clamp arm front end is provided with right clamp arm elbow, left clamp arm elbow rotates rear and right clamp arm elbow laminating around bearing pin, at the left clamp arm elbow medial surface relative with right clamp arm elbow, be equipped with seal wire groove and two seal wire grooves match, two seal wire grooves are offered along its corresponding left clamp arm elbow direction and right clamp arm elbow direction respectively; At left clamp arm and the intersection of the circle of shaking hands, be provided with left clamp-buckle tooth bar, at right clamp arm and the intersection of the circle of shaking hands, be provided with right clamp-buckle tooth bar, left clamp-buckle tooth bar is relative with right clamp-buckle tooth bar and can be interlocked, on described left clamp-buckle tooth bar, be provided with scale strip, scale strip is positioned on the length direction of the end face that left clamp-buckle tooth bar contacts with right clamp-buckle tooth bar, and the width of described left clamp-buckle tooth bar is greater than the width of right clamp-buckle tooth bar.

The setting of left clamp-buckle tooth bar and right clamp-buckle tooth bar, it is controlled and do not need staff to fix that its mutual manner can make stretching pliers strut width, the setting of scale strip, can make to expand on the numerical value that width is directly reflected in scale strip, the setting of left clamp arm elbow, right clamp arm elbow and seal wire groove, can make seal wire insert smoothly.

The medial surface relative with right clamp arm elbow at described left clamp arm elbow is equipped with intermeshing anti-slop serrations.It is seamless that anti-slop serrations can make left clamp arm and right clamp arm close up, and makes seal wire groove there is no unnecessary gap and insertion smoothly.

During use, the seal wire of sending into through trocar guiding is placed in to seal wire groove, slowly Guided Percutaneous tracheotomy stretching pliers is sent in incision of trachea, holding the circle of shaking hands makes it to come closer, slowly tong arm elbow is expanded, and observed buckle teeth bar and move the variation that causes scale strip numerical value, be fully expanded to required width, fasten buckle teeth bar and can make it fixing, and under the guiding of seal wire, send into the tracheal casing pipe of different model according to different patients.

This utility model compared with prior art, tool has the following advantages: this device structure is simple, expansion accurately, easy to operate, time saving and energy saving, one-handed performance can be fixing by incision of trachea expansion, efficiently solves because operating the excessive excessive problem of incision of trachea that causes of exerting oneself, also make surgical field of view expose clear, be beneficial to the carrying out of operation.
