Abstract
The utility model relates to a structural improvement for a tool used for cutting and thinning tissues with pathological changes when performing otolaryngological surgeon. The improved tool comprises a cutter, a shaft, a fore arm, a bent body, and a back arm. The utility model is characterized in that the shaft is composed of a front shaft, a back shaft and a middle soft shaft that are integrally connected, and the soft shaft has a spiral ring structure and a diameter of 2-8 mm. The utility model has advantages of simple and reasonable structure, low noise, and low vibration.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind ofly when being used for ent surgery, and pathological tissues is cut improvement with the tool construction of reconditioning.
Background technology
During ent surgery, bore with electronic ear pathological tissues is cut and reconditioning, the electronic ear of general straight-bar bores owing to influence doctor's sight line of performing the operation, and therefore all is happy to employing elbow type structure.The elbow ear of prior art bores, mostly adopt the bevel gear structure, transmission of power when realizing that diaxon is angled, adopt the bevel gear structure, exist complex structure, the requirement on machining accuracy height, and also its rotating speed is generally up to 16000-30000 rev/min, because the existence of its back lash, noise is bigger.
Summary of the invention
This utility model mainly is to solve existing in prior technology: owing to adopt bevel gear structure, its complex structure, requirement on machining accuracy height, the technical problem of the bigger grade of noise.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: by cutter, axle, pull end, curved body, back handle, it is characterized in that: axle is fused by front axle, rear axle and intermediary flexible axle.
As preferably, its flexible axle adopts spiral coil formula structure.
As preferably, the flexible axle diameter is 2mm-8mm.
As preferably, the formed angle of turn α=10-90 of front axle and rear axle.
Therefore, the utlity model has simple and reasonable, characteristics such as noise is low, vibration is little.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in the figure, the left end of flexible axle 6 connects with front axle 3 on being installed in bearing 4, the right-hand member of flexible axle 6 connects with rear axle 7 on being installed in bearing 4, fork cover 8 is equipped with in the lower end of rear axle 7, be used for accepting power, the left end of front axle is equipped with cutter 1, is used for patient's focus is polished, and all parts are installed in the endoporus cavity of being made up of pull end 2, curved body 5 and back handle 9.During work, the motor component that ear bores inserts back handle endoporus, and with the electric machine main shaft high speed rotating, power passes to front axle 3 by flexible axle 6 to rear axle 7 with fork cover 8, drives cutter 1 rotation at last.
