Bendable planer tool device

Abstract

The invention discloses a bendable planer tool device. The bendable planer tool device comprises an outer-layer protection sleeve, a rotatable inner pipe arranged inside the outer-layer protection sleeve and a planer tool bit, wherein one end of the rotatable inner pipe is used for being connected with a rotating driving device, and the other end of the rotatable inner pipe is connected with the planer tool bit; a metal pipe is arranged at the tail end of the outer-layer protection sleeve, and a memory alloy pipe is arranged at the front end of the outer-layer protection sleeve; the rotatableinner pipe comprises multiple single-section inner pipe units and multiple hinging connecting pieces, the multiple single-section inner pipe units are sequentially connected, the single-section innerpipe unit located at the tail end is specifically connected with the planer tool bit, and any two adjacent single-section inner pipe units are connected through the corresponding hinging connecting pieces. The bendable planer tool device can be bent in the certain angle range, and better adapts to different to-be-cut positions inside the human tissue and cutting angle adjustment accordingly, and thus operative efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bendable planer device. Background technique [0002] As we all know, in orthopedic clinical operations, doctors will use a lot of planers. In the specific structure of the traditional planer, the planer is generally composed of a stainless steel outer sheath tube, a rotatable hollow inner tube, a corresponding suction structure, and a planer head for cutting. [0003] The main working functions of the above-mentioned planer are: planing and removing the articular cartilage separated from the subchondral bone, repairing the worn cartilage defect area; removing the torn meniscus, repairing and forming the worn and ruptured meniscus; removing burrs, cutting or grinding the bone or partial or complete resection, trimming hypertrophy and hypertrophy of inflammatory synovial tissue, etc., in preparation for follow-up surgery. [0004] However, in the traditional planer...

AI Technical Summary

Problems solved by technology

[0004] However, in the traditional planer device, the outer sheath tube is often made of stainless steel, which cannot be bent, and the internal rotatable inner tube (which is connected to the planer head) cannot be effectively bent, which causes the planer to cut The position is not easy to adjust, and thus cannot better adapt to different positions to be cut inside the human tissue

Unable to achieve different cutting angle adjustment operations, which seriously affects the efficiency of surgery
