Operating handle for laser lithotripsy

Abstract

The invention relates to an operating handle for laser lithotripsy, which has a hollow tubular structure. The operating handle is used for containing optical fiber which is connected into the operating handle by a laser stone breaker and extrudes out. One side branch pipe is formed by extending out of the main body of the operating handle and is used for connecting a vacuum suction system; the side branch pipe is communicated with a pipeline in the main body of operating handle for vacuum suction in the stone breaking process for breaking and sucking stones. The main body / side branch pipe of the operating handle is provided with a pressure valve for controlling attraction; the front end of the main body of the operating handle is also provided with a suction pipe, the optical fiber is connected into the operating handle by the laser stone breaker and penetrates out of the suction pipe, the suction pipe is a probe, and the other end of the main body of the operating handle is provided with an optical fiber protection pipe via a lock nut. The invention provides a rigid carrier for soft optical fiber in laser stone breaking, has simple and practical integral structure, is easy to assemble and disassemble and has convenient operation.

Description

technical field [0001] The invention relates to a medical device for treating stones, in particular to a novel operating handle for laser lithotripsy used in laser lithotripsy for treating urinary stones. Background technique [0002] The current treatment methods for stones mainly include extracorporeal shock wave lithotripsy (ESWL) and internal lithotripsy. With the development of laparoscopic technology, intracorporeal lithotripsy has been more and more widely used. Internal lithotripsy is currently common and pneumatic lithotripsy, ultrasonic lithotripsy and laser lithotripsy.

Problems solved by technology

[0005] Although laser lithotripsy technology has irreplaceable advantages of other methods, the current laser lithotripsy generally uses optical fibers to directly perform lithotripsy. However, the material of the optical fiber itself is thin and soft, and it is difficult to operate in terms of movement and positioning; and The laser lithotripter does not have the ability to remove stones, and the postoperative cleaning ability is weak, which affects observation and operation, and is likely to cause certain safety hazards

The above factors limit the application and popularization of this technology
