Abstract

The utility model relates to a sounding button used after total excision operation of the larynx, which is the improvement of the existing sounding button. The oesophagus end is the structure of a check valve. The trachea end is provided with an air flow collection part, the air flow collection part is composed of a trachea end fixed disk and an air collecting pipe. Using the utility model, the patient's sound is sonorousness, and the patient's speaking is clearness; the patient can not have the phenomenon of aspiration at eating time. Because the utility model is fixation, so as to can not occur the situations of dropping or sliding.

Description

Sounding button used after total excision operation of larynx

This utility model relates to the technical field of surgical instrument that is used for throat.

The main Therapeutic Method of laryngeal carcinoma is to implement laryngectomy, and the misery of postoperative patient maximum is to have lost pronunciation, speech function.1980, the USA Magazine reported first by a kind of pronunciation knob (Singer MI and Blom ED:an Endscopic Technigue for Restoration of voice after Laryngectomg of Singer and the success of Blom joint research and development, Ann Otol Rhinol Laryngol, 1980.89:529～533).This pronunciation knob is still adopted by countries in the world at present, but its success rate is about 70% only, and the main cause that influences its voice effect is:

1, an end of insertion esophagus is the duckbill opening, is difficult for by the air communication mistake;

2, advance duckbilled distortion and open on the feed, have a little food slag can enter the pronunciation knob, the mistake suction occurs;

3, trachea end air inlet is less, enters the deficiency of air of pronunciation knob, causes difficulty of pronunciation;

4, the trachea end does not have fixed disk, esophagus end fixed disk weakness, thereby fixing not firm.

The purpose of this utility model will overcome the shortcoming of prior art exactly, and it is loud to design a kind of pronunciation, and speech clearly is used for the pronunciation knob of total laryngectomy postoperative.

The utlity model has breather, end at breather is fixed with esophagus end fixed disk, in breather end, the esophagus end fixed disk outside check valve is housed, the other end at breather is provided with air-flow set portion, is fixed with the cervical fixation handle of strip in the end of air-flow set portion.Air-flow set portion is made up of with the discharge of the curved tangent plane in outer end that is connected with trachea end fixed disk the trachea end fixed disk that funnelform thin end is connected with the breather end.The one valve guard circle that is fixed on the esophagus end fixed disk is arranged around check valve.

The utlity model has following advantage:

1, owing to the effect of air-flow set portion, air-flow can be concentrated and promptly enter UE very much, and it is loud not only to pronounce, and it is clear to talk, and laborsaving;

2, because of the esophagus end is a check valve, mistake can not take place inhale, diet is normal;

3, fixing safe, can not deviate from or slide.

Accompanying drawing has provided embodiment of the present utility model.Wherein Fig. 1 is a schematic perspective view, and Fig. 2 is the center longitudinal section of Fig. 1.(1) is check valve among the figure, and (2) are esophagus end fixed disk, and (3) are breather, and (4) are air-flow set portion, comprise the gentle pipe end fixed disk of discharge (5) (6), and (7) are the cervical fixation handle, and (8) are the valve guard circle.

In the present embodiment, except that check valve (1), remainder is by the silicone rubber single injection-molded, check valve (1) is thick 0.3mm, the silicone rubber thin slice of diameter 10mm, its top 1/3 are adhesively fixed on the esophagus end fixed disk (2), and all the other 2/3 can be with the air-flow activity.Cervical fixation handle (7) is vertically fixed on the outermost end of discharge (5).

Claims

1, a kind of vocal rehabilitation after laryngectomy, has breather (3), be fixed on the esophagus end fixed disk (2) on the breather (3), and cervical fixation handle (7), it is characterized in that, check valve (1) is equipped with in end at esophagus end fixed disk (2) outside, breather (3), and the other end of breather (3) is provided with air-flow set portion (4).

2,, it is characterized in that air-flow set portion (4) is made up of with the discharge (5) of the curved tangent plane in outer end that is connected with trachea end fixed disk (6) the trachea end fixed disk (6) that funnelform thin end is connected with breather (3) end according to the described vocal rehabilitation after laryngectomy of claim 1.

3, according to the described vocal rehabilitation after laryngectomy of claim 1, it is characterized in that check valve (1) around a valve guard circle (8) that is fixed on the esophagus end fixed disk (2) arranged.
