A kind of medical power reciprocating saw blade drive mechanismTechnical 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 dailyCheng Zhong, is to carry out cutting saw, it is necessary to expend many strength of operating personnel manually by artificial mode, and increased patient'sPain, although also have some electronic cast-cutting saws on the market, but due to its simple structure, easily produce in use incline andDeviate, 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 andThe 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 machineStructure, including motor, the first umbrella tooth, the second umbrella tooth, crankshaft-link rod, saw blade retaining sleeve, spring, saw blade, left fairlead, right guidingSet, 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 umbrellaTooth is intermeshed together；The second umbrella tooth also links together with one end axle of crankshaft-link rod；The crankshaft-link rod it is anotherIt 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 sawA 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 junctionOuter 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 describedA left case is coated with the outer surface of left fairlead and right fairlead；The right fairlead and saw blade retaining sleeve junctionA 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 leftFairlead 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 deviateedSaw 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 resiliencyEnergy.

Specific embodiment：
As shown in figure 1, this specific embodiment uses following technical scheme：A kind of medical power reciprocating saw blade drive mechanism, bagMotor 1, the first umbrella tooth 2, the second umbrella tooth 3, crankshaft-link rod 4, saw blade retaining sleeve 5, spring 6, saw blade 7, the left fairlead 8, right side is included to leadTo set 9, right case 10 and left case 11；Axle is connected with a first umbrella tooth 2 on the output shaft of the motor 1；First umbrellaTogether with tooth 2 is intermeshed with the second umbrella tooth 3；The second umbrella tooth 3 also links together with one end axle of crankshaft-link rod 4；InstituteThe other end and the left side of saw blade retaining sleeve 5 for stating crankshaft-link rod 4 are movably connected；The inside of the saw blade retaining sleeve 5 setsThere is a spring 6；A saw blade 7 is clamped with the saw blade retaining sleeve 5, the saw blade 7 is in contact with spring 6；The bent axleA left fairlead 8 is coated with the outer surface of connecting rod 4 and the junction of saw blade retaining sleeve 5；The outer surface of the saw blade retaining sleeve 5On be coated with a right fairlead 9；A left case 11 is coated with the outer surface of the left fairlead 8 and right fairlead 9；InstituteA right case 10 is coated with the outer surface for stating right fairlead 9 and the junction of saw blade retaining sleeve 5.
Wherein, the motor 1 is variable-frequency motor or servomotor；The spring 6 is disk spring；The left case 11Outer surface is provided with anti-slip veins.
Use state of the invention is：During work, the high-speed rotation of motor 1 provides power, by driving the first umbrella tooth 2 and theThe engaged transmission of two umbrella teeth 3, drives crankshaft-link rod 4 to rotate, and saw blade retaining sleeve 5 is driven by crankshaft-link rod 3 and realizes left and right high frequencyMove back and forth, in the presence of left fairlead 8 and right fairlead 9, the high-frequency reciprocating of saw blade retaining sleeve 5 will not produce inclination when movingAnd deviation.
General principle of the invention and principal character and advantages of the present invention, the technology of the industry has been shown and described abovePersonnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification thisThe principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changesChange and improvement all fall within the protetion scope of the claimed invention, the claimed scope of the invention by appending claims and itsEquivalent thereof.
