Embodiment Construction

[0033] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figure 1~3 As shown, the laser scalpel with continuously adjustable defocus distance includes a knife body 2. The knife body 2 is in the shape of an irregular cylinder as a whole, and the center is a cavity. An adjusting lens barrel 11 can be embedded in the knife body in an axially slidable manner. 2. In the cavity, the focusing lens 12 is installed in the adjusting lens barrel 11, and a defocus adjusting rotary cylinder 5 is set on the knife body 2 and is adjustablely connected with the adjusting lens barrel 11. The defocus adjusting rotary cylinder 5 is hollow and cylindrical, and can be It rotates freely on the knife body 2, and its inner side is provided with an internal thread, and its front end cooperates with the stepped thrust part of the knife body 2, and the outer front part of the defocus adjustment drum 5 is provided with a h...

Abstract

The invention relates to a laser scalpel, and particularly relates to a laser scalpel with continuously adjustable out-of-focus distance for laser operations and laser cosmetic surgeries. The laser scalpel comprises a scalpel body and an adjusting lens barrel, wherein the adjusting lens barrel can be embedded into the cavity of the scalpel body in an axially sliding way and is internally provided with a focusing lens; an out-of-focus adjusting rotary barrel is sleeved on the scalpel body and is adjustably connected with the adjusting lens barrel. By virtue of the adjusting lens barrel and the out-of-focus adjusting rotary barrel, the continuous adjustability of laser focus, diameter and energy density is achieved, and the problem that the laser scalpel needs to be replaced on occasions with different requirements is solved.

Description

technical field [0001] The invention relates to a laser scalpel, in particular to a laser scalpel with continuously adjustable defocus distance used for laser surgery and laser cosmetic surgery, and belongs to the field of medical equipment. Background technique [0002] Laser is monochromatic light with certain penetrating power and precise focus; laser surgery uses a certain energy laser beam to irradiate biological tissue, and the instantaneous high temperature generated causes photocoagulation and photovaporization of the irradiated tissue. Laser surgery has advantages that traditional surgery cannot match: basically no need for hospitalization, small surgical incision, no bleeding during the operation, no secondary infection, minimally invasive, etc. Since various operations, especially those used in different medical fields, require laser scalpels with different specific functions, many new laser scalpel technologies have been led, invented and created. [0003] The e...
