Abstract

An ultrasonic therapeutic gun is composed of a handle, a therapeutic head and a gun tube connected between handle and therapeutic head. Its therapeutic head can be inserted to the particular position of human body, such as throat.

Description

A kind of ultrasonic medical treating gun

Invention field

The present invention relates to a kind of apparatus for ultrasonic therapeutic treatment, relate in particular to a kind of treatment rifle for the treatment of disease of pharynx.

Background technology

Utilizing the ultrasonic therapy pharyngitis is a kind of new ultrasonic therapy technology.Ultrasound wave has the aggregation in good energy permeability and the biological tissue, can give the ultrasonic irradiation of pharyngitis mucosa doses, make it to produce damage to a certain degree, and the sensitivity of pharyngitis mucosa is reduced, thereby the course of reaction of blocking-up pharyngitis reaches the purpose of controlling this disease.

More existing treatment rifles generally comprise handle, gun barrel and are connected treatment head on the gun barrel.During treatment, gun barrel and treatment head are extend into the patient from the oral cavity pharyngeal, launches ultrasound wave simultaneously and treat.Described handle, gun barrel and treatment head are in turn connected into the straight ultrasonic therapeutic rifle of a bar in placed in-line mode, the end face or the side-emitted ultrasound wave of treatment head.

When treatment during pharyngitis, because the particularity of pharyngitis site of pathological change, the treatment rifle needs enter from the oral cavity, and as shown in Figure 1, the treatment rifle is through mouth 01, oral cavity 02, enters into pharyngeally 04, and wherein the pharyngitis site of pathological change is around pharyngeal 04.This treatment head for the treatment of rifle of will seeking medical advice can extend into patient throat and can be to the whole pharyngeal scanning treatment that carries out.But existing treatment rifle or can not adapt to pharyngeal planform because of the cause or for want of flexible cause of straight gun barrel, thereby often the treatment head can not be delivered to appropriate treatment position, or can only can not implement treatment to whole pharyngeal site of pathological change by end face or side-emitted ultrasound wave because for the treatment of head.

Summary of the invention

The objective of the invention is for overcoming the above-mentioned deficiency of existing treatment rifle, provide a kind of can ultrasonic therapeutic head be delivered to execute easily control the position, and whole pharyngeal site of pathological change is implemented the ultrasonic medical treating gun of treatment.
