Abstract
The invention provides bone surgery instruments and particularly relates to a micro cutter. The micro cutter comprises an alloy cutting blade, a cutting blade protective cover, an elongated transmission shaft, a bearing, a transmission shaft protective sleeve, a water injection pipe and a chip absorption pipe, wherein the alloy cutting blade is fixed at the top end of the elongated transmission shaft, and external rotating power drives the alloy cutting blade to rotate through the elongated transmission shaft; the cutting blade protective cover is integrally welded with the transmission shaft protective sleeve; the water injection pipe is located on the outer side of the cutting blade protective cover, and water is dripped on the alloy cutting blade; the chip absorption pipe is mounted at a chip outlet of the cutting blade protective cover; the transmission shaft is arranged in the cutting blade protective cover through the bearing. The micro cutter is sterilized before being used, the water injection pipe is connected with normal saline, the absorption pipe is connected with a vacuum extractor, the external rotating power clamps the other end of the elongated transmission shaft and drives the alloy cutting blade to rotate, water is injected to cool a metal steel plate and wash away metal chips while the metal steel plate is cut, and the metal chips flowing out are absorbed by the absorption pipe and are removed.
Description
Technical field
The present invention relates to a kind of bone surgery set and be specifically related to body internal fixation steel plate cutting tool in a kind of bone surgery.
Background technology
Take out in operation at orthopaedics implant steel plate screw; often can run into normal accident of taking out difficulty; by drilling screw, injured bone, orthopedist can wait until that means finally take out steel plate and screw, but may cause serious consequence to the damage of osseous tissue, and medical tangle is following.
In clinical, take out the accident of difficulty if run into implant and abandon taking out, can cause again patient's loss economically and animally misery, medical tangle is still inevitable.How run into above-mentioned unexpected time neither injured patients osseous tissue successfully can take out metal implant again, medical miniature sickle solves this problem, after using medical miniature sickle, segmentation after the cutting of implants in vivo steel plate can be taken out and the osseous tissue of not injured patients.
Author is not had to carry out studying and design similar instrument to this at present through the literature search of prior art.
Summary of the invention
In order to overcome the deficiency of existing operating theater instruments and operation method, when running into implants in vivo steel plate and screw takes out difficulty accident, use the medical miniature sickle with protective casing, when not increasing patient's soft tissue and osseous tissue damage, implants in vivo steel plate sectional is cut into the little block plate that can screw be driven separately to rotate, water lubrication and cooling is added in cutting process, metal fines is attracted device by flowing water and removes, although whole operating process can extend to some extent than normal taking-up, but than existing drilling screw, the method of injured bone is quick, greatly improve operation exception treatment efficiency, reduce patient's wound open-assembly time, reduce operation risk, and effectively protect patient.Structure of the present invention is simple, easy to use, successful.
A kind of medical miniature sickle is provided to comprise alloy cutting blade according to an aspect of the present invention, cutting blade protective cover, lengthen power transmission shaft, bearing, power transmission shaft protective casing, water injection pipe, chip suction pipe, wherein, described alloy cutting blade is fixed on the top that described lengthening turns power transmission shaft, external rotary power drives alloy cutting blade to rotate by lengthening power transmission shaft, described alloy cutting blade guard shield and power transmission shaft protective casing integrally welded, water injection pipe is positioned at outside alloy cutting blade guard shield, on water instillation alloy cutting blade, what chip suction pipe was installed on cutting blade guard shield cuts out bits place, power transmission shaft loads cutting blade guard shield by bearing.
First medical miniature sickle sterilization treatment water injection pipe is connect normal saline before using; chip suction pipe connects vacuum extractor; external rotary power clamps the other end lengthening and turn power transmission shaft; alloy cutting blade is driven to rotate; in cutting body, steel plate water filling is simultaneously lowered the temperature and washes away metal fillings; the metal fillings flowed out is attracted to remove by chip suction pipe, and vital tissue can be protected with gauze.
of the present invention is owing to adopting Integral design; rotation alloy cutting blade and power transmission shaft are provided with protective sleeve; and be provided with a set of water filling and chip recycling device; use simple to operate; cutting speed is fast, is cut steel plate without intensification, soft tissue near reliably protecting; safety is high, thoroughly can solve steel plate and take out the generation that there is duty adverse events in hospital at need.
