An optical fiber sleeve for a holmium laser lithotripsy device that protects kidney tissue

Abstract

The invention provides an optical fiber sleeve of a holmium laser lithotripsy device for protecting kidney tissue, belonging to the technical field of holmium laser lithotripsy devices. The optical fiber sleeve of the holmium laser lithotripsy equipment includes an optical fiber, a double-layer hollow optical fiber sleeve, a fiber filament rod, and a fiber filament fixing cap. The double-layer hollow optical fiber is sheathed with an outer layer film and an inner layer film, a hollow structure is formed between the inner layer film and the outer layer film, and a plurality of fiber filament rods are arranged, and a fiber filament rod is arranged inside the fiber filament rod. , its structure is the same as that of the double-layer hollow fiber sleeve. The two sides of the outer film of the double-layer hollow fiber sleeve are provided with a plurality of liquid outlet holes, and the angle between the two liquid outlet holes at the same height is 150-170 ° between. The invention has simple structure and low cost, does not affect the optical path of the optical fiber, has no complicated electronic structure, can be sterilized after use, reduces the use cost, and can greatly reduce the kidney damage of kidney stone patients.

Description

Technical field: [0001] The present invention belongs to the technical field vivo laser lithotripsy device, relates to an optical fiber protective sleeve renal tissue holmium device. Background technique: [0002] Holmium laser is yttrium aluminum garnet (YAG) as the active medium, sensitizing ions doped chromium (Cr), thulium ion energy transfer (Tm), active ions holmium (Ho) of the laser crystal (Cr: Tm: Ho: YAG) new solid-state laser device is made of a laser pulse generated. Can be used in urology, ENT, dermatology, gynecology department surgery. The laser surgery is non-invasive or minimally invasive surgery, the patient's pain treatment is very small. [0003] Holmium laser lithotripsy compared with conventional extracorporeal shock wave lithotripsy, pneumatic lithotripsy, with strong security and broad applicability. Extracorporeal shock wave lithotripsy is the use of electromagnetic or electrohydraulic shock wave generator emitting high-energy shock waves penetrating the ...

Problems solved by technology

Acid stones are not effective; neodymium lasers cannot be used for lithotripsy due to their less precise

The traditional laser lithotripsy is just a skin and an optical fiber. The laser of the lithotripsy can be transmitted to the optical fiber sleeve of the holmium laser lithotripsy equipment through the optical fiber. The optical fiber sleeve of the holmium laser lithotripsy equipment is just a hard glass fiber. The probe can transmit the laser light to the position of the kidney stone, crush the kidney stone, and excrete it through the renal tubule along with the urine, but the optical fiber sleeve of the traditional holmium laser lithotripsy equipment is harmful to the kidney tissue The damage is relatively large, and the surrounding kidney tissue will heat up due to the side effects of the laser, causing irreversible cell damage and damaging kidney function
