Description

Technical Field

[0001] The present invention relates to the technical field of hair transplantation, and in particular to a hair follicle separation method and a device for hair transplantation. Background Art

[0002] At present, the hair follicle separation device for hair transplantation is a medical device specially designed for use in hair transplantation surgery. Its main function is to effectively separate and extract hair follicle units during the operation.

[0003] Existing hair follicle extraction devices have obvious deficiencies. Traditional devices lack precise fixing and positioning mechanisms, which makes it difficult to ensure the integrity and activity of hair follicles during the extraction process, thus affecting the success rate and effectiveness of hair transplant surgery. At the same time, traditional equipment usually does not have intelligent scanning functions and cannot accurately scan and locate the hair follicles on the patient's head, resulting in limited accuracy in hair follicle extraction. In addition, traditional devices also lack angle adjustment functions, which may increase the risk of physical damage to the scalp during the extraction process, causing unnecessary pain and recovery difficulties for patients. Existing hair follicle extraction devices need to be further improved and enhanced in terms of fixing stability, extraction accuracy, and reduction of physical damage to meet clinical needs and patient expectations; Therefore, the present application adopts a jet nozzle to extract hair follicles. The jet nozzle adopts high-pressure water power to cut the adhesion of hair follicles, and can use high-pressure water power for debridement treatment. Compared with conventional metal sharp instrument debridement therapy, the jet nozzle adopts hydrodynamic debridement with its short operation process, low-damage wound control, precise cutting and separation, efficient removal of bacteria and bacterial biofilm, simultaneous entrainment of waste and reduction of pollution, etc., which meets the requirements of hair follicle extraction.
