Description

Oscillating Saw {Oscillating saw for surgery}

The present invention relates to a surgical oscillating saw, and more particularly, to a surgical oscillating saw to minimize the cutting deviation caused by the rotation of the disposable cutting oscillating saw for use in surgery.

In general, when an incision or cutting, a hole, or a pin needs to be inserted into a bone in a surgical operation, a surgical oscillating saw or drill is used. A conventional surgical oscillating saw is used by a manual or motor An automatic method of rotating at high speed is used.

Such surgical oscillating saw or cutting drill is a device for cutting or grinding the protruding jawbone by forming a cut in the tip portion in a circular or fan shape.

Here, the oscillating saw or cutting drill is usually coupled to a power tool, and then the bone is operated in conjunction with the rotation or reciprocation of the power tool, and as a known example, Korean Patent Application No. 1999-0034321 “Intraoral fracture Cutting saw ”.

The known example as described above has been filed in order to overcome the shortcomings of the fixed partially rotatable saw, and the swinging rotatable saw is detachably mounted to cut or grind the bone to be treated.

However, the known example as described above has a problem in that the thickness of the cutting becomes thick when cutting due to a deviation caused by rotation of the surgical oscillating saw or the cutting drill when cutting or grinding.

Therefore, the main object of the present invention is to provide a surgical oscillating saw to minimize the deviation of the saw when cutting the bone and the like in the surgical operation so as to form the cutting thickness as thin as possible.

In order to achieve the above object, the surgical oscillating saw of the present invention forms a pair of guide blocks to correspond to each other, but each of the main body and taper-shaped guide ball formed on the guide block, and coupled to the guide ball of the main body, Since the outer periphery is formed in a tapered shape, the rotary shaft is in close contact with the guide ball, the saw is coupled to the rotary shaft, and the driving motor is operated by applying power to the rotary shaft. The basic features of the technical configuration are to minimize the shrinkage and to perform the surgery more efficiently.

Therefore, the surgical oscillating saw of the present invention is supported by the tapered rotary shaft in the tapered shape of the guide block of the main body in close contact with the reciprocating rotation while minimizing play so that the cutting portion can be cut as thin as possible, surgical By minimizing the reduction of cuts such as bones caused by surgery, it is possible not only to perform the surgery more efficiently, but also to improve the prognosis after export and to shorten the recovery period.

Figure 2 is a perspective view showing a part of the surgical oscillating saw in accordance with the present invention.
Figure 3 is a front view showing a partially cut in the surgical oscillating saw according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the surgical oscillating saw 100 of the present invention to form a pair of guide block 111 to correspond to each other, but the tapered shape guide ball 112 in the guide block 111 The rotating shaft 120 and the rotating shaft coupled to the guide ball 112 of the main body 110 and the guide ball 112 of the main body 110 to form a tapered shape, so as to be in close contact with the guide ball 112, respectively. The saw 130 is coupled to the 120, and the drive motor 140 for reciprocating rotation by applying power to the rotary shaft 120.

The main body 110 is formed in a substantially gun shape, but forms a pair of guide blocks 111 that face each other at a predetermined position, and each guide ball 112 forms a guide block 111 and a guide ball 112. The inner circumference of the to form a tapered shape and each guide ball 112 is to be formed in the tapered extension line.

Therefore, the upper guide ball 112 is formed to become narrower in the same line to the lower guide ball 112.

The rotation shaft 120 is formed to have a tapered shape of the outer periphery to be in close contact with the tapered guide hole 112.

The fastening means 122 is provided at the lower end of the rotating shaft 120 so that the outer circumferential edge of the rotating shaft 120 and the inner circumferential edge of the guide ball 112 are in close contact with each other.

Furthermore, the outer circumferential edge of the rotating shaft 120 and the inner circumferential edge of the guide ball 112 are preferably LM processed so that the reciprocating rotation can be performed smoothly even in a close state.

Furthermore, the rotation shaft 120 may be formed by being coupled to the outer periphery of the direction switching means 121.

The saw 130 is formed in a circular or fan shape, but forms a blade at the tip.

Here, the shaft 130 is formed in the center of the shaft hole 131 and the fastening means 132 is provided in the shaft hole 131 to be coupled using the fastening means 132 on the top of the rotary shaft 120.

The drive motor 140 is connected to the direction switching means 121 of the rotating shaft 120 by the power transmission means 141 to apply a reciprocating rotational power.

In addition, it is preferable to have an operation button 142 to control the drive motor 140.

On the other hand, the rotating shaft 120 and the guide ball 112 is formed in the upper and lower light narrow tapered shape mutually, but may also be formed to be in close contact with each other from the upper by forming the upper and lower light.

Referring to the operation of the surgical oscillating saw 100 according to the present invention as follows.

First, when the driving motor 140 is operated by operating the operation button 142, the rotary shaft 120 is reciprocated through the power transmission means 141 and the direction switching means 121, so that the cutting coupled to the rotary shaft 120 The blade 130 is reciprocated to allow cutting or cutting of bones and the like in a surgical operation.

In particular, the rotating shaft 120 is supported in close contact with the guide hole 112 of the guide block 111 of the main body 110 to reciprocate rotation, thereby reciprocating rotation while minimizing the clearance due to the reciprocating rotation, making the cutting portion as thin as possible. It can be cut.

In addition, the outer periphery of the rotary shaft 120 and the guide ball 112 is formed in a tapered shape to be in close contact with the outer periphery of the rotary shaft 120 and the inner periphery of the guide ball 112 by pulling as much as possible with the fastening means 122. Because it adheres so strongly that the play rarely occurs it is possible to cut the cutting site as thin as possible.

Therefore, it is possible to minimize the reduction of cuts such as bones caused by the surgical operation to perform the surgery more efficiently, and to improve the prognosis after the export and to shorten the recovery period.
