Problems solved by technology

[0002] Laparoscopic bladder lithotripsy is a common operation in urology. In the past, bladder calculus lithotripsy was performed by inserting ureteroscope components through the cystoscope sheath. Fluid often overflows through the mouth of the scope sheath, which cannot form an effective flushing circuit, and the bladder is always in an empty state. Once the bladder mucosa bleeds, the surgical field of view is blurred; Displacement makes it difficult to observe stone fragments; during the operation, it is often necessary to repeatedly remove the ureteroscope components to fill the bladder, which often affects the speed and efficiency of stone fragmentation, and even has to stop the operation

Abstract

The invention discloses a device for treating bladder calculi. The device comprises a ureteroscope component and a prostate resectoscope component, wherein the inner cavity at one end of the prostate resectoscope component is connected with a water seal cap; and the inner cavity of the water seal cap is inserted into the ureteroscope component through an inner sheath of the prostate resectoscope component. The device disclosed by the invention has simple structure and low manufacturing cost, is convenient to operate, and makes full use of the combination of the existing medical instruments and a water seal cap; and the device offers a clear visual field in a continuous perfusion surgery, and realizes safe and quick surgery operation and high efficiency. The device is suitable for the bladder calculi lithotripsy.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for treating bladder stones. Background technique [0002] Laparoscopic bladder lithotripsy is a common operation in urology. In the past, bladder calculus lithotripsy was performed by inserting ureteroscope components through the cystoscope sheath. Fluid often overflows through the mouth of the scope sheath, which cannot form an effective flushing circuit, and the bladder is always in an empty state. Once the bladder mucosa bleeds, the surgical field of view is blurred; Displacement makes it difficult to observe stone fragments; in order to fill the bladder during the operation, it is often necessary to repeatedly remove the ureteroscope components, which often affects the speed and efficiency of stone crushing, and even has to stop the operation. Contents of the invention [0003] The object of the present invention is to provide a device for treating bladder calculi with simple ...
