Abstract
The invention discloses a kind of medical power reciprocating saw blade drive mechanism, including motor, the first umbrella tooth, the second umbrella tooth, crankshaft-link rod, saw blade retaining sleeve, spring, saw blade, left fairlead, right fairlead, right case and left case；The present invention has rational in infrastructure simple, low production cost, it is easy for installation, it is multiple functional, medical personnel can be facilitated, reduce patient's pain and the reciprocating saw blade drive mechanism for inclining and deviateing will not be produced in use, motor high-speed rotation is converted into the motion of saw blade retaining sleeve or so high-frequency reciprocating, simple structure, small power consumption, transmission efficiency, left fairlead and right fairlead play positioning action to saw blade retaining sleeve, the saw blade for being inclined due to saw blade retaining sleeve and deviateing and produce is avoided to fluctuate, so as to ensure that the security of operation, spring is also provided with saw blade retaining sleeve, realizing saw blade has shock-absorbing capacity.
Description
Technical field
The present invention relates to medical saw blade technical field, more particularly to a kind of medical power reciprocating saw blade drive mechanism.
Background technology
During hospital cures the sickness to save the patient, especially in orthopaedics, usually may require that and use saw blade, used in daily
Cheng Zhong, is to carry out cutting saw, it is necessary to expend many strength of operating personnel manually by artificial mode, and increased patient's
Pain, although also have some electronic cast-cutting saws on the market, but due to its simple structure, easily produce in use incline and
Deviate, be not appropriate for medically using, so it is not enough to make up this to need a kind of technology on the market.
The content of the invention
The purpose of the present invention is that and provide a kind of medical power reciprocating saw blade drive mechanism in order to solve the above problems,
There is provided it is a kind of be applied to medical treatment, medical personnel can be facilitated, reduce patient's pain and will not produce in use incline and
The reciprocating saw blade drive mechanism of deviation.
In order to solve the above problems, the invention provides a kind of technical scheme：A kind of medical power reciprocating saw blade driving machine
Structure, including motor, the first umbrella tooth, the second umbrella tooth, crankshaft-link rod, saw blade retaining sleeve, spring, saw blade, left fairlead, right guiding
Set, right case and left case；Axle is connected with a first umbrella tooth on the output shaft of the motor；The first umbrella tooth and the second umbrella
Tooth is intermeshed together；The second umbrella tooth also links together with one end axle of crankshaft-link rod；The crankshaft-link rod it is another
It is movably connected on the left of one end and saw blade retaining sleeve；The inside of the saw blade retaining sleeve is provided with a spring；The saw
A saw blade is clamped with piece retaining sleeve, the saw blade is touched with spring interface；The crankshaft-link rod and saw blade retaining sleeve junction
Outer surface on be coated with a left fairlead；A right fairlead is coated with the outer surface of the saw blade retaining sleeve；It is described
A left case is coated with the outer surface of left fairlead and right fairlead；The right fairlead and saw blade retaining sleeve junction
A right case is coated with outer surface.
Preferably, the motor is variable-frequency motor or servomotor.
Preferably, the spring is disk spring.
Preferably, the outer surface of the left case is provided with anti-slip veins.
Beneficial effects of the present invention：The present invention has simple, low production cost rational in infrastructure, easy for installation, multiple functional,
Medical personnel can be facilitated, patient's pain is reduced and the reciprocating saw blade drive mechanism for inclining and deviateing will not be produced in use,
Motor high-speed rotation is converted into the motion of saw blade retaining sleeve or so high-frequency reciprocating, simple structure, small power consumption, transmission efficiency is left
Fairlead and right fairlead play positioning action to saw blade retaining sleeve, it is to avoid the generation because saw blade retaining sleeve is inclined and is deviateed
Saw blade fluctuates, and so as to ensure that the security of operation, spring is also provided with saw blade retaining sleeve, and realizing saw blade has resiliency
Energy.
