Abstract

The invention discloses a calculus breaking and clearing attraction probe device with cohesively aligned laser fibers, comprising a hollow probe, wherein a tail end of the hollow probe is connected with a vacuum extractor through a connection pipe; a front end of the hollow probe is provided with a protruded structure on the upper part; and at least one fiber channel capable of containing at least two laser fibers is installed inside the hollow probe; the fiber channel is provided with a cohesive fiber outlet on the protruded structure and a fiber inlet on the tail end of the hollow probe; and front end of each laser fiber in the fiber channel is slightly bent to round up to be arranged on the cohesive fiber outlet to form a cohesive fiber calculus breaking and clearing structure, and the hollow probe is formed by a slotted probe and a slotless probe equipped at the end of the slotted probe. The device provided by the invention is featured by large calculus impact area, high calculus breaking efficiency, good calculus breaking effect regardless of hard or soft calculus and long service life, and is capable of rapidly breaking the calculus and removing broken pieces by absorbing.

Description

technical field

[0001] The invention relates to a probe, and more specifically relates to a laser fiber cohesive arrangement type rubble-clearing stone-clearing probe rod device used for lithotripsy and removal of urinary calculi. Background technique

[0002] Urinary calculus is a common and frequently-occurring disease in my country. Although the treatment of urinary stones at home and abroad has entered the era of minimally invasive surgery from open surgery, the high rate of residual stones after surgery is still a prominent problem in clinical work.

[0003] At present, the existing pneumatic ballistic lithotripsy has a better effect, but it is a physical method. The large impact force has caused bleeding and it is difficult to control the size of the fragments. The stones bounce everywhere due to the large impact force and it is difficult to locate. Ultrasonic lithotripsy has certain effects, but it is almost useless for stones with relatively high hardness such as ca...
