Costal cartilage cutting and crushing device

Abstract

The invention relates to the field of medical instruments, in particular to a costal cartilage cutting and crushing device. The device comprises a shell and a cartilage placement part which are detachably connected, and a cavity of the shell sequentially comprises a pressing cavity, a cleaning cavity and a transition cavity from the top to the bottom; a cutting assembly is arranged in the shell and comprises a gang tool body and a cutting part which are connected, the gang tool body extends into the cleaning cavity from the pressing cavity, the cutting part is arranged in the cleaning cavity, a cleaning part is arranged in the cleaning cavity, and the cleaning part sequentially comprises a gang tool body passing groove and a cutting part passing groove which are communicated from top to bottom; a rotary pressing part is arranged at the end, away from the cartilage placement part, of the cutting assembly, and an elastic piece matched with the rotary pressing part is arranged on the cavity wall of the pressing cavity. According to the device, the operation time of a doctor in an operation can be effectively shortened, the fatigue degree caused by repeated operation processes can be reduced, the labor cost can be greatly reduced, and the device has a good industrialization prospect.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a costal cartilage cutting and pulverizing device. Background technique [0002] In costal cartilage rhinoplasty, it is often necessary to use small granular crushed cartilage (cartilage granules with a diameter less than 1mm) to shape the tip of the nose and bulge the bridge of the nose. Costal cartilage is located between the ribs and the sternum, and removal of a small portion has no effect on the stability of the entire thorax, so it is widely used. [0003] At present, the costal cartilage is generally taken from a small section of the sixth, seventh, and eighth ribs in the surgery. It is cut according to the situation of the individual surgical replacement part. After cutting, it is cut and crushed with traditional instruments and knives. In the process, physicians or physician assistants need to use cutting tools to repeatedly cut costal cartilage for a long time....

AI Technical Summary

Problems solved by technology

[0003] At present, the costal cartilage is generally taken from a small section of the sixth, seventh, and eighth ribs in the surgery. It is cut according to the situation of the individual surgical replacement part. After cutting, it is cut and crushed with traditional instruments and knives. In the process, physicians or physician assistants need to use cutting tools to repeatedly cut costal cartilage for a long time. The operation process is repeated and easy to fatigue, and other forces such as pressure, stirring force and other cutting forces to crush costal cartilage will damage the costal cartilage. The activity of the rib cartilage is destroyed, resulting in a decrease in the activity of the costal cartilage after the final shaping, and the survival rate is also greatly reduced

Further, it will prolong the time for costal cartilage surgery
