Carbon dioxide laser instrument for cutting dermatofibroma lesion tissues

Abstract

The invention relates to the technical field of carbon dioxide laser instruments, in particular to a carbon dioxide laser instrument for cutting dermatofibroma lesion tissues. The instrument comprisesan output positioning cylinder, the output positioning cylinder is of a cylindrical structure, a clamping connector is integrally arranged at the upper end of the output positioning cylinder, a circle of positioning ring is fixedly welded to the outer ring at the lower end of the output positioning cylinder, an air guide rib is fixedly arranged on the inner ring of the output positioning cylinder, the air guide rib is of a spiral structure, and the outer ring of the output positioning cylinder is sleeved with an air bellow. An air inlet cavity and an air outlet cavity can be fully utilized, airflow forms vortexes in the air inlet cavity and the air outlet cavity, dust accumulation in the air outlet cavity is avoided, and the effects of being free of maintenance and disinfection and free of dead corners can be achieved; due to the fact that air inlet holes and air outlet holes are evenly distributed in the cylinder wall of the output positioning cylinder, air inlet and air outlet are even, and the situation that torrent affects laser output stability can be avoided; and the air bellow is simple in installation structure, high in sealing performance and high in practicability.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide lasers, in particular to a carbon dioxide laser for cutting dermatofibroma lesion tissue. Background technique [0002] Carbon dioxide laser is a medical device mainly used for cutting, vaporizing, carbonizing, coagulating and irradiating human tissues to achieve therapeutic purposes. Widely used in ENT, dermatology, cosmetology, gynecology, neurosurgery and other surgical operations. It mainly treats vascular skin diseases, pigmented skin diseases, malignant tumors, benign tumors or cysts, keratosis, hyperplasia and other skin diseases, but it still has the following disadvantages in actual use: [0003] During fractional laser treatment, dandruff and dust are likely to affect the lens, affecting the smoothness of the lens, thereby affecting the treatment effect. Moreover, the laser burns dander and other sundries to form smoke, which may not only affect the treatment of patients Finally...

[0003] During fractional laser treatment, dandruff and dust are likely to affect the lens, affecting the smoothness of the lens, thereby affecting the treatment effect. Moreover, the laser burns dander and other sundries to form smoke, which may not only affect the treatment of patients After the sensitive skin causes infection, it also affects the performance and laser intensity of the light-emitting components of the fractional laser therapy instrument
