Water cooling structure of laser surgical instruments

Abstract

The invention relates to a water cooling structure of laser surgical instruments. The water cooling structure comprises a circulatory seat, an outer pipe, an inner pipe, a circulatory pump, an outer circulatory interlayer is arranged between the inner wall of the outer pipe and the outer wall of the inner pipe, a light-guide optical fiber is inserted in the inner pipe, an inner circulatory interlayer is arranged between the outer wall of the light-guide optical fiber and the inner wall of the inner pipe, a liquid return cavity and a liquid outlet cavity are arranged in the circulatory seat; the outer pipe is communicated with the liquid outlet cavity; the liquid return cavity is communicated with the inner pipe; the circulatory seat is provided with a liquid return interface; the circulatory seat is provided with a liquid outlet interface; the outlet and the inlet of the circulatory pump are respectively communicated with the liquid outlet interface and the liquid return interface; a lens is arranged at the front end of the outer pipe; the head of the inner tube is positioned in the outer tube. In the water cooling structure of laser surgical instruments, the inner circulatory interlayer and the outer circulatory interlayer are formed by the outer pipe and the inner pipe sleeved outside the light-guide optical fiber, the cooling liquid is controlled through the circulatory pumpto circulate between the inner circulatory interlayer and the outer circulatory interlayer, the heat generated on the light-guide optical fiber and the lens is taken away, the light-guide optical fiber and the lens are prevented from being overheated, the structure is simple, the volume is small, and the light-guide optical fiber can move forwards and backwards to adjust the irradiation intensityof the lens.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a water cooling structure of a laser surgical instrument. Background technique [0002] Compared with traditional scalpels, laser knives have less bleeding and higher work efficiency. However, when the existing laser knives perform operations on narrow places such as intracranial, optical fibers are usually used to guide the laser light. Effect. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a water-cooling structure for a laser surgical instrument. [0004] The technical solution adopted by the present invention to solve the technical problem is: a water-cooled structure of a laser surgical instrument, including a circulation seat, an outer tube arranged at the head of the circulation seat, an inner tube arranged at the head of the circulation seat, a circulation pump, the outer diameter of the inner tu...
