Bladder calculus lithotripter

Abstract

The present invention relates to a bladder calculus lithotripter. The bladder calculus lithotripter comprises a lithotriptoscope outer sheath, a lithotriptoscope inner sheath, a multifunctional endoscope and a hole obturator, the lithotriptoscope outer sheath comprises an outer sheath conduit, a water outlet valve seat and a water inlet valve seat; a circulating channel can be formed between the water outlet valve seat and the water inlet valve seat; the lithotriptoscope inner sheath comprises an inner sheath conduit and an inner sheath base seat; the hole obturator comprises a guide head anda hole obturator base seat; the multifunctional endoscope comprises an endoscope conduit and an operating handle; the multifunctional endoscope is also provided with a light source system, an inward vision system and a lithotriptic channel; and the lithotriptic channel is used for placing an air pressure trajectory probe rod or an optical fiber. Advantages are as follows: the bladder calculus lithotripter can provide a treatment channel for a holmium laser lithotripsy, can also be used for carrying out an air pressure trajectory lithotripsy, forms a water circulation loop, can keep clear visual field, is moderate in thickness, can reduce probability of urethral stricture, reduces urethral injury, and is safe to use, convenient to operate and beneficial to washing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bladder calculus lithotripsy device. Background technique [0002] At present, holmium laser lithotripsy under cystoscopy or improved holmium laser lithotripsy under resectoscope is used for most bladder stones, which can use holmium laser lithotripsy, but pneumatic lithotripsy cannot be used; The ballistic lithotripsy method can only be replaced by ureteroscopy, and the lithotripsy of larger stones cannot be performed. In addition, most of bladder calculus lithotripsy adopts holmium laser lithotripsy under cystoscope, without circulating water washing, and the intraoperative vision is not clear, especially when encountering prostate and bladder bleeding, the clarity is poor, and stones are easily missed; while the improved Holmium laser lithotripsy under the resectoscope of the prostate, on the one hand, the resectoscope is thicker, F26 size, which is easy to damage t...

Problems solved by technology

[0002] At present, holmium laser lithotripsy under cystoscopy or improved holmium laser lithotripsy under resectoscope is used for most bladder stones, which can use holmium laser lithotripsy, but pneumatic lithotripsy cannot be used; The ballistic lithotripsy method can only be replaced by ureteroscopy, and the lithotripsy of larger stones cannot be performed

In addition, most of bladder calculus lithotripsy adopts holmium laser lithotripsy under cystoscope, without circulating water washing, and the intraoperative vision is not clear, especially when encountering prostate and bladder bleeding, the clarity is poor, and stones are easily missed; while the improved Holmium laser lithotripsy under the resectoscope of the prostate, on the one hand, the resectoscope is thicker, F26 size, which is easy to damage the urethra; The probe rod should be bent, which is easy to rub against the mirror body and reduce the energy of lithotripsy, so pneumatic lithotripsy under modified resectoscope is rarely used clinically

Most hospitals only have one lithotripsy tool, and cystoscopic lithotripsy has many disadvantages, and improved resectoscope can only use holmium laser

There are still many units without holmium laser equipment, only pneumatic ballistics, and pneumatic ballistic lithotripsy can only be replaced by ureteroscopes, which is inconvenient to operate and even less clear

[0003] Chinese patent application: CN104434309A discloses a portable lithotripsy all-in-one machine, including three energy output ports, namely ultrasonic output interface, air pressure output interface, and holmium laser output interface, so that the treatment can be flexibly selected according to needs. stone; and includes an accessory placement assembly, the accessory placement assembly includes a support ear, a support ear two, and an optical fiber receiver, the support ear is used to place a collection bottle, and the support ear two is used to place Ultrasonic handle and pneumatic ballistic handle, the optical fiber receiver is used to place the optical fiber, so that each component is placed in a proper position in an orderly manner, which is more convenient when it needs to be used, and the energy output of the lithotripsy equipment is relatively simple, so that it cannot The inter-conversion of the various crushing means leads to the more cumbersome problem when replacing the crushing means, but it does not solve the problem of single function of the operation end and low flexibility
