Problems solved by technology

[0005] The applicant previously invented a sliced ​​costal cartilage harvester (patent number 2016201571832), but in practice, it was found that the angle of the sliced ​​costal cartilage slicer was not correct during the operation, and it was not possible to drag and cut the costal cartilage well during use. , and the grooved cutting head hinders the removal of costal cartilage, resulting in long operation time and poor effect

Abstract

The invention provides a pull type cartilago costalis sheet cutter which comprises a handle, a cutting rod and a cutting head. The handle is connected to one end of the cutting rod. The cutting head is connected to the other end of the cutting rod. A cutting knife is arranged on the cutting head. A blade of the cutting knife can be pulled to cut a cartilago costalis sheet on the surface of cartilago costalis. The cutting rod protrudes to one side. The protruding direction of the cutting rod is opposite to the fitting direction of the cutting knife and the cartilago costalis. The cutting rod protrudes to one side and does not fit a human body any more, only the blade of the cutting knife fits the cartilago costalis, the pull type cutting does not bear the resistance of the human body, and the cutting of the cartilago costalis can be well achieved.

Description

technical field [0001] The invention belongs to surgical instruments, in particular to a dragging costal cartilage sheet cutter. Background technique [0002] Costal cartilage rhinoplasty refers to a cosmetic surgery that uses autologous costal cartilage transplantation as a material for rhinoplasty. In the field of plastic surgery, the most reasonable material for rhinoplasty is recognized as autologous cartilage, among which ear cartilage, nasal septum cartilage and costal cartilage are mostly used. The medical community has gradually realized the benefits of autologous cartilage, especially autologous costal cartilage, and it has been more and more popularized in clinical practice, and good results have been achieved. [0003] The current routine costal cartilage rhinoplasty is to take a 3cm long incision under the breast contour line or the surface of the seventh costal cartilage under local anesthesia to expose the perichondrium, peel off the periosteum, and cut out th...
