Abstract
The utility model discloses a motor-driven bone saw which comprises a saw cover, a saw blade, a motor and a power line, wherein the motor is installed on the saw cover; the lower edge part of the saw cover is provided with a supporting plate which can adjust the height of the saw blade which is exposed out of the saw cover; the front end shaft of the supporting plate is connected with the saw cover; a rear end part of the supporting plate is provided with an adjusting and fastening knob fastened on the saw cover; the lower edge of the supporting plate is provided with a platform vertical to the saw blade; the overlapping part of the saw cover and the rear end of the supporting plate and the end surface of one part which is exposed upwards from the overlapping part are provided with indication scales for saw blade exposing height. The motor-driven bone saw has the advantage of simple structure, sawing depth can be controlled when thoracic surgery is carried out in a breastbone median approach, and the working difficulty of the medical personnel is lightened.
Description
Technical field:
This utility model belongs to the medical apparatus technical field, is a kind of electric bone saw specifically.
Background technology:
At present, when breastbone center approach carries out thoracic surgery, make mostly and cut breastbone with a chainsaw, and existing electric saw does not have any location facilities, can only rely on medical worker's working experience to determine the sawing weight, increased great work difficulty to the medical worker.
Summary of the invention:
The purpose of this utility model provides a kind of a kind of electric bone saw that can control the sawing weight when breastbone center approach carries out thoracic surgery.
The technical solution of the utility model is: a kind of electric bone saw, comprise saw cover, saw blade, motor, power line, motor is installed on the saw cover, following portion at the saw cover, there is an adjustable saw blade to expose the supporting plate of saw cover height, the front end axle of supporting plate is connected on the saw cover, and rearward end has the tightening knob of adjusting to be fastened on the saw cover, and the bottom of supporting plate has and the vertical platform of saw blade; The saw cover upwards has saw blade to expose the height indicating graduation on the exposed portions serve end face with the eclipsed part in supporting plate rear end and this place.
Handle is managed in described saw cover top.
Expose height for the ease of regulating saw blade, nose on the other hand can be set in the rearward end of supporting plate.
During use, can by adjusting knob, regulate the height that saw blade exposes supporting plate,, like this, just can limit the degree of depth of saw because the bottom of supporting plate is a platform according to cutting part, patient's build.
The beneficial effects of the utility model are: simple in structure, and when carrying out thoracic surgery, breastbone center approach can control the sawing weight, alleviated medical worker's work difficulty.
