CO2 laser treating hand tool

Abstract

The invention discloses a CO2 laser treating hand tool. The CO2 laser treating hand tool comprises a beam parallel part, a beam dividing part and a diaphragm part connected in sequence from top to bottom, the beam parallel part comprises a first housing body and a beam parallel lens set, and an incident laser beam irradiates into the first housing and passes through the beam parallel lens set to become parallel beam; the beam dividing part comprises a second housing and a beam separating lends set, and a parallel beam irradiated by the beam parallel part irradiates into the second housing and passes through the beam separating lens set to become multiple parallel beams; the diaphragm part comprises a third housing and an iris diaphragm arranged in the third housing, the iris diaphragm is used for adjusting the area of an irradiated beam, and the first housing, the second housing and the third housing are connected in sequence and the upper ends and the lower ends of the first housing, the second housing and the third housing are all opened. The CO2 laser treating hand tool improves the operability of a treating doctor, achieves the purpose of accordingly adjusting the size of a CO2 laser beam facula according to angiomas with different sizes, avoids the unnecessary laser injury, and improves the treating effect.

Description

technical field [0001] The present invention relates to a kind of medical instrument, especially relates to a kind of CO 2 Laser therapy hand tools. Background technique [0002] Hemangioma is a congenital benign tumor or vascular malformation, which is more common at birth or shortly after birth. It originates from residual embryonic hemangioblasts, and active endothelial-like germs invade adjacent tissues to form endothelial-like cords. Hemangioma is formed by connecting with the remaining blood vessels. The blood vessels in the tumor form a self-contained system and are not connected with surrounding blood vessels. At present, pulsed dye lasers are used to treat hemangiomas as we know. However, the dye laser emits a wavelength of 585nm or 595nm, and the depth of damage to hemangiomas is limited, and the maintenance cost and consumable costs of dye lasers are relatively high; The laser damage depth emitted by the 1064nm laser is too deep, and it is not the absorption pea...

AI Technical Summary

Problems solved by technology

But continuous CO 2 Laser damage to tissues is non-selective in clinical practice. Surgical treatment is often accompanied by side effects such as skin scars. While cutting the lesion, it will also damage normal tissues to varying degrees, so it is not suitable for surgeries with high requirements. treatment, severely limited CO 2 Further application of laser in medical treatment
