In summary, the rib cutting device for operation of the application can adapt to the sizes of ribs of different patients during operation, and the ribs are fully wrapped and fixed through the first clamping groove 211 and the second clamping groove 221 during operation, so that cutting can be realized within the wrapping area, and damage to important organs such as surrounding liver and the like caused by rib cutters during use can be effectively prevented. The rib cutting device cuts the rib by a rotary force-out mode, and the cutting mode can effectively cut harder ribs in a limited area range. The rib cutting device for the operation can effectively solve the problems that the rib is difficult to cut under the endoscopic or direct-view operation and the adjacent organs are easy to damage, and has good industrial prospect.
In conclusion, the application effectively overcomes various defects in the prior art and has high industrial utilization value.
The above embodiments are merely illustrative of the principles of the present application and its effectiveness, and are not intended to limit the application. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the application. Accordingly, it is intended that all equivalent modifications and variations of the application be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
