Abstract

The invention relates to the technical field of medical instruments, and discloses a cartilage extractor for plastic surgery. The cartilage extractor comprises a shell with a handle, wherein a triggerrod is hinged on the shell; an extension pipe is arranged at the front end of the shell, a hook is arranged at one end, far away from the shell, of the extension pipe, and the front end of the hook is a round blunt metal sheet; a force transmission rod is inserted into the extension pipe, one end of the force transmission rod extends into the shell, and a blade is arranged at the other end of theforce transmission rod; a plurality of tooth sockets are arranged at the end of the force transmission rod positioned in an inner cavity of the shell; and an edge of the hinge end of the trigger rodis provided with teeth which can be meshed with the tooth sockets. According to the invention, a costal cartilage is hooked by the hook, and then the trigger rod controls a blade to cut the costal cartilage, so that the stripped costal cartilage can be hooked and cut. The whole process can be operated by one person, operation is simple, and operation time is shortened. In addition, the blade partof the blade can be attached to the inner wall of the hook, so that the costal cartilage can be completely cut at one time, and safety of a cutting process and integrity of the broken end of the costal cartilage are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cartilage extractor for plastic surgery. Background technique [0002] In recent years, with the development of plastic surgery technology and the improvement of people's aesthetic standards, as well as the influence of foreign plastic surgery colleagues, more and more doctors have begun to pay attention to the fine structure and shape of the tip of the nose. At present, in rhinoplasty, autologous costal cartilage combined with silica gel or puffy material for comprehensive rhinoplasty and nose shape adjustment has become the mainstream trend, especially for nasal tip shape reshaping. Autologous costal cartilage is recognized as the best material. Transplantation of costal cartilage can significantly change the shape and rotation of the nasal tip, and play a role in raising and lowering the nasal tip.
