Description

Vocal cord polyp cutter

Technical Field

The invention relates to a medical apparatus, in particular to a vocal cord polyp cutter.

Background

With polyps in the vocal cords, closure of the vocal cords is hindered and the vibration frequency of the vocal cords is affected. The voice of the patient becomes low, and the voice and the hoarseness are serious, so that the life quality of the patient is seriously affected. If the polyp is too large it can block the respiratory tract and even cause dyspnea, thus requiring this surgical removal of the polyp. The traditional operation mode is to operate with scissors or a knife under a supporting mirror, but once the excision is too much, the voice is easy to be made to be a permanent hoarseness, and the excision is too little, and the voice is easy to relapse. The effect of the surgery is completely determined by the level of the physician's surgery and the uncertainty is too great. At present, a vocal cord polyp cutter with simple structure and good cutting effect is not yet available.

Disclosure of Invention

The invention aims to solve the defects of the prior art and provides the vocal cord polyp cutter with simple structure and good cutting effect.

The invention solves the technical problems by adopting the technical scheme that: the vocal cord polyp cutter comprises a gun body, wherein the gun body is connected with a fixed handle, the rotary handle is connected with the fixed handle through a shaft pin, a fixed block is arranged on the front side of an inner cavity of the gun body, a sleeve is connected in front of the fixed block, a sliding block is arranged on the rear side of the inner cavity of the gun body, the rotary handle is connected with the sliding block and can drive the rotary handle to slide along the axis of the gun body, a cutting pipe is connected in front of the sliding block and stretches into the sleeve, a window is formed in the front end of the sleeve, a cutting end is arranged at the front end of the cutting pipe, and a cuttable fit is formed between the rotary handle and a window edge cutting part on the window.

Preferably, the cutting tube end section has a recess, the cutting end is located on the recess, and the window is matched with the recess along the shape of the cutting part. The cut wound can be kept flat.

Preferably, the root of the rotating handle is provided with a gear which is matched with a rack arranged at the bottom of the sliding block. The cutting action can be kept smooth.

Preferably, the fixing block is in rotatable fit with the gun body, grooves uniformly distributed along the circumferential direction are formed in the fixing block, and a screw is arranged below the gun body and protrudes into the cavity to be matched with the grooves. The cutting angle is convenient to adjust.

Preferably, two symmetrical notches are formed in the cross section of the end of the cutting tube, and can be used as the cutting end. Is convenient for cutting the polyps of the vocal cords at the two sides.

The invention has the beneficial effects that: the invention has reasonable structure and good cutting effect, and cut wounds are kept relatively flat.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

embodiment one: as shown in fig. 1, a vocal cord polyp cutter comprises a gun body 1, wherein the gun body 1 is connected with a fixed handle 2, a rotating handle 3 is connected with the fixed handle 2 through a shaft pin 4, a fixed block 6 is arranged on the front side of an inner cavity of the gun body 1, a sleeve 7 is connected in front of the fixed block 6, a sliding block 5 is arranged on the rear side of the inner cavity of the gun body 1, a gear is arranged at the root of the rotating handle 3 and matched with a rack arranged at the bottom of the sliding block 5, the rotating handle 3 is connected with the sliding block 5 to drive the rotating handle to slide along the axis of the gun body 1, a cutting pipe 8 is connected in front of the sliding block 5, and the cutting pipe 8 stretches into the sleeve 7.

As shown in fig. 2 and 3, the front end of the sleeve 7 is provided with a window 9, the cross section of the end part of the cutting tube 8 is provided with a notch, the cutting end 10 is positioned on the notch, and the cutting end 10 and a window edge cutting part 11 on the window 9 form a cuttable fit.

When the multifunctional cutting device is used, firstly, the sleeve 7 stretches into the vocal cords to find the position of the polyp 14, other devices are used for pulling the polyp, the window 9 is used for catching the polyp, the rotating handle 3 is pulled to drive the sliding block 5 to slide forwards, so that the cutting tube 8 is driven to move forwards, the cutting end 10 and the window edge cutting part 11 form a cutting action, and the polyp is cut off. As shown in fig. 4, when the polyp is pulled out, the root of the connection between the polyp and the vocal cords is in an extended state, if the cutting tube 8 without a notch is used for cutting, at this time, the cutting end 10 is in the shape of the cross section of the end part of the cutting tube 8, namely, in the shape of a circular arc, the cutting surface is concave, and after the polyp is cut, the root is restored to a loose state, the wound surface is concave more and more, a pit is formed, and the restoration is difficult; and the cutting end 10 with a notch is adopted, so that the cutting surface slightly protrudes outwards, and the wound surface is kept flat relative to the surrounding parts after the root of the polyp is restored to a loose state after the polyp is cut.

Embodiment two:

the fixed block 6 and the gun body 1 can be in running fit, grooves 12 uniformly distributed along the circumferential direction are formed in the fixed block 6, a screw 13 protruding into the cavity is arranged below the gun body 1 and matched with the grooves 12, on one hand, the position of the fixed block 6 is relatively fixed, on the other hand, the fixed block 6 can rotate in a plurality of gears (the same as the grooves 12 in number), the sleeve 7 is driven to rotate, and the window 9 has different directions. Two symmetrical notches are formed in the cross section of the end part of the cutting tube 8 and can be used as cutting ends 10, so that the angle of the window 9 can be conveniently adjusted on the basis of not changing the operation direction of the handle, and polyps on two sides of the vocal cords can be simultaneously cut.

In addition to the embodiments described above, other embodiments of the invention are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the invention.
