Holmium laser optical fiber guide device and treating device provided with resectoscope and guide device

Abstract

The invention discloses a holmium laser optical fiber guide device and a treating device provided with a resectoscope and the guide device, and relates to the field of medical supplies. The holmium laser optical fiber guide device comprises a flexible guide pipe and a guide device head which is connected to one end of the guide pipe, the guide pipe is internally provided with an optical fiber hole, a cavity which is communicated with the optical fiber hole is formed in the guide device head, and a flexible sealing cap covers the guide device head. The treating device provided with the resectoscope and the guide device comprises the resectoscope, the resectoscope comprises an electroexcision ring pipe and an operating handle connector provided with a sealing part, the electroexcision ring pipe is internally provided with an electroexcision ring hole, the operating handle connector is internally provided with an electroexcision ring inlet hole, and the sealing part is internally providedwith a sealing part hole which is communicated with the electroexcision ring inlet hole. The treating device further comprises the holmium laser optical fiber guide device, the guide pipe penetratesthrough the sealing part hole, the electroexcision ring inlet hole and the electroexcision ring hole, the guide pipe and the sealing part are sealed, and the guide device head is located at the outerside of the operating handle connector. The holmium laser optical fiber guide device and the treating device provided with the resectoscope and the guide device are applicable to bladder intracavity lithoclasty or urethra stenosis holmium laser incision.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a holmium laser fiber guide and a treatment device with a resectoscope and the guide. Background technique [0002] At present, the treatment of bladder calculi includes open surgery to remove stones and intravesical lithotripsy without surgery. There are four types of lithotripsy in the bladder cavity: bladder forceps, pneumatic ballistics, ultrasonic lithotripsy, and holmium-induced lithotripsy. [0003] Intravesical lithotripsy is carried out with powerful bladder forceps for crushing stones in the bladder cavity. A special lithotripsy mirror should be used, and because the lithotripsy forceps occupy more channels in the cavity, the mirror body is thinner, the amount of light transmitted is less, and the field of vision is dim. , and water can not be flushed while flushing, so that the field of vision remains clear all the time. It can be seen clearly when the stone is just car...

AI Technical Summary

Problems solved by technology

However, there is no dedicated holmium laser bladder lithotripsy, and the holmium laser can only be used to perform bladder urethral lithotripsy or intraurethral incision through cystourethroscopy.

[0005] The cystoscope has only one water inlet channel. It cannot be flushed into the water while letting the water flow out. During operation, the water can only enter or exit intermittently.

The holmium laser performs bladder urethral lithotripsy or intraurethral incision through cystourethroscopy, resulting in stone fragments and bladder wall bleeding, which will cause dim vision, affect the normal operation, increase the possibility of bladder injury, and even cause May lead to failure of intracavitary lithotripsy and have to be changed to open surgery to remove stones
