Abstract
A kind of sagittal saw, including shell, main shaft, connecting rod, pivot pin, pendular body and cutter holding device, the main shaft is mounted on inside shell, its tail portion is equipped with power input interface, end is equipped with the eccentric skew shaft being connected with connecting rod one end, the other end of the connecting rod is hinged on the center of pendular body by the pivot pin being mounted on pendular body, the drawbacks of the present invention overcomes the drive mechanisms of existing sagittal saw provides a kind of sagittal saw for reducing noise, reduction vibration, reduction fever, raising revolving speed, raising procedure efficiency and operational safety.
Description
Technical field
The present invention relates to a kind of Medical surgical apparatus more particularly to a sagittal saws.
Background technique
Sagittal saw is a kind of common tool that bone tissue cutting is carried out in surgical operation, needs to realize and quickly and accurately cut
Bone tissue, sagittal saw common problem is that noise is big, vibration is big, fever is serious, revolving speed is lower at present, in surgical procedure
Middle safety is poor, adversely affects to patient.
In the prior art, the transmission mechanism of sagittal saw is usually to utilize the inner wall of the sliding sleeve compressing pendulum slot on eccentric shaft complete
At cutting is swung, such as Chinese patent CN200720063569.8 and CN02226668.2 attached drawing disclosure of that, now with
For CN02226668.2, analyze the transmission mechanism there are the drawbacks of: front axle during the swing, due to the pendulum of its tail portion
Width of the slot on section B-B is variation, therefore puts slot and cover between its slide inside set, and there are when sliding sleeve operating
Resigning gap.
The sagittal saw of this transmission mechanism, noise is big when work, influences surgical environments, meanwhile, the sagittal saw work of the structure
Impact vibration can be generated when making, saw blade is caused to be beated, causes saw blade kinematic accuracy not high, have a fixing to the safety of operation
Ring, in addition, the eccentric shaft of this sagittal saw, sliding sleeve and pendulum slot are all easier to wear, fever is serious when work, revolving speed compared with
It is low, reduce procedure efficiency.
Therefore, how sagittal saw reduces noise, reduces vibration, reduce fever, improve revolving speed, becomes those skilled in the art
Important technological problems urgently to be resolved.
Summary of the invention
In view of this, the present invention provides a kind of sagittal saw, the transmission mechanism band of the sagittal saw under the prior art can be avoided
The drawback come, reaching reduces noise, reduces vibration, reduce fever, propose high-revolving purpose.
To achieve the above object, the present invention is achieved by the following technical solutions: a kind of sagittal saw, including shell, master
Axis, connecting rod, pivot pin, pendular body and cutter holding device, the shell is interior to be equipped with to step down when connecting rod and pendular body movement
First cavity, the main shaft are mounted on inside shell, and tail portion is equipped with power input interface, and end is equipped with to be connected with connecting rod one end
Eccentric skew shaft, the other end of the connecting rod is hinged on the center of pendular body by the pivot pin being mounted on pendular body, institute
The second cavity being equipped with inside pendular body for stepping down when link motion is stated, two sides are equipped with the fulcrum shaft being connected with shell, described
Cutter holding device is mounted on the front end of pendular body, the axial line of the eccentric skew shaft of the axial line and its front end of the main shaft, institute
The axial line and the connecting rod for stating pendular body two sides fulcrum shaft by the center that pivot pin is hinged on pendular body intersect at one
Point.
Preferably, the shell include inner casing, cuff inner casing outer surface front casing and with inner casing nesting be connected
Rear casing.
Preferably, it is equipped with bearing in the hole at the both ends of the connecting rod, being wherein also equipped on the end face in the hole of one end can hold
By the bearing of axial load.
Preferably, the cutter holding device includes the resilient sleeve being inserted into the front aperture of pendular body and is locked at swing
Lock sleeve on the front end of body.
Beneficial achievement of the invention, compared with prior art, a kind of the advantages of sagittal saw disclosed by the invention are: reducing
Noise reduces vibration, reduces fever, improves revolving speed.
