Shows an explanatory view in which the punch shaft portion and the handle portion are separated. In the figure, A indicates a punch shaft portion and B indicates a handle portion. The punch shaft portion A is composed of a fixed blade 1 having a blade portion at its tip, and a slide blade 2 placed on the fixed blade and moving in the longitudinal direction. The slide blade 2 is located closer to the tip of the fixed blade. The ridge 3 provided on the upper surface of the fixed blade toward the base side and the vertical groove 5 of the circular collar 4 provided on the base portion of the fixed blade are fitted to slide in the longitudinal direction. Further, the slide blade 2 has a blade attached to a tip 7 facing the fixed blade tip blade portion 6. Further, the base side of the slide blade 2 projects outward from the groove of the base circular collar 4 of the fixed blade 1, and the rear end 8
Is formed into a spherical shape, and is fitted in a spherical receiving groove portion of a drive shaft of a handle portion described later. A nut 9 for joining and fixing the punch shaft portion side to the handle portion side is fitted and attached to the base portion side of the punch shaft portion. The inner wall of the front end of this nut is the base circular collar 4 of the fixed blade.
The stopper pin 10 is fixed to the fixed blade 1 so as not to come off from the punch shaft portion. The handle B has one handshake 11 and a joint screw 12
The other handshake 13 that is attached so that it can be opened and closed with the guide pipe 1 that is attached and fixed to the upper end of the one handshake 11.
4 and the other handshake 1 fitted in this guide pipe
The upper end head portion 15 of the head 3 is slid back and forth in the guide pipe / drive shaft 16. As shown in FIG. 3, the drive shaft 16 includes a notch recess 17 into which one handshake head 15 fits, and a grooved ball recess 18 into which the base-side rear end sphere 8 of the slide blade 2 of the punch shaft fits. Has been formed. In the figure, 19 and 20 are leaf springs attached between the handshake 11 and 13. As described above, the angle-type bone punch of the present invention is formed by loosening the nut 9 attached to the base side of the punch shaft portion A by screwing the nut 9 with the guide pipe 14 on the handle portion B side. Since the fixed joint between the circular flange 4 on the base side and the guide pipe 14 on the handle side is loosened, the punch shaft section A side can freely rotate with respect to the handle section B side. With the blade edge direction of the desired direction, the direction of the handle part remains the same,
You can change it freely. If the nut 9 is loosened, the punch shaft side can be separated from the handle side.

を交換して使用できる等の優れた特長を有する。The angle-type bone punch of the present invention allows the punch shaft portion and the handle portion to be easily attached and detached, and the joint portion between the punch shaft portion and the handle portion to be rotatable, so that the angle can be set at any angle ( Can be fixed by joining (anywhere 360 °). Therefore, since no angle blind spot is generated in the surgical operation, the surgical posture of the operator is not overpowered, it is easy to secure a visual field during surgery, and the blade width and shaft length adapted to the surgical site It has excellent features such as the ability to replace the punch size with the selected long and short sizes.
