Problems solved by technology

Existing lithotripsy equipment does not have a fixation effect on stones, and it is easy to cause the laser to hit the human tissue instead of the stone, causing damage to human tissue, which increases the difficulty and time of the operation

Abstract

The invention discloses a pair of laser lithotripsy fixing forceps, and relates to the technical field of medical instruments. The forceps comprise a main body and light-guide fibers, wherein a clamping assembly is arranged at one end of the main body, and a driving rod is arranged in the main body in a sliding manner; one end of the driving rod is connected with the clamping assembly, and the other end of the driving rod is connected with a driving handle; the clamping assembly comprises two clamping jaws which are oppositely arranged; at least one clamping jaw is internally provided with a first optical fiber channel; an outlet of the first optical fiber channel is opposite to the other clamping jaw; a second optical fiber channel is arranged in the main body; and the optical fiber sequentially penetrates through the second optical fiber channel and the first optical fiber channel. According to the laser lithotripsy device, by arranging the clamping assembly, the situation that whenlaser lithotripsy is conducted on calculus, the calculus jumps or escapes out of the visual field is avoided, then the laser lithotripsy efficiency is improved, and injuries of laser to human tissue are reduced.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a laser lithotripsy fixation forceps. Background technique [0002] Urinary system stones are generally caused by kidney stones being blocked in narrow places such as the bladder, ureter, and kidney during the excretion process. Stones may induce bacterial infection, leading to pyonephrosis and high fever. Because the stones hinder the discharge of urine, the bacteria cannot be discharged in time, and in severe cases, it can lead to sepsis, which is life-threatening. At present, the use of holmium laser lithotripsy in the treatment of urinary calculi has become the mainstream surgical plan. When holmium laser lithotripsy is performed with the help of an endoscope, the stone is subjected to the impulsive force of normal saline perfused to keep the field of view clear and the forward impulsive force when the holmium laser is released. Under the action of these two fo...
