Bladder renal pelvis stones extraction lens

Abstract

The present invention provides a bladder pyeloscope, comprising a pyeloscope sheath, a pyeloscope body, a lithotomy forceps and clamp module, a lithotomy forceps and clamp passage pipe, a chippings passage pipe, an optical fiber passage pipe and an endoscopic imaging module. The end of the pyeloscope sheath is provided with a washing liquid passage opening. One ends of the lithotomy forceps and clamp passage pipe, the chippings passage pipe and the optical fiber passage pipe are respectively communicated with a pull rod inlet at the pyeloscope body, a chippings passage opening and an optical fiber inlet; the other ends are inserted into the pyeloscope sheath and are extended to the end of the pyeloscope sheath. The chippings passage opening is communicated with a chippings passage. The gap inside the pyeloscope sheath is a liquid washing passage which is communicated with the washing liquid passage opening. The lithotomy forceps and clamp module comprises a jaw and a pull rod which isput through the lithotomy forceps and clamp passage to be connected with a handle. The lithotomy forceps and clamp module is arranged outside the end of the lithotomy forceps and clamp passage pipe. One end of the endoscopic imaging module is connected with the pyeloscope body, and the other end is arranged at the end of the optical fiber passage pipe. The present invention has the functions of diagnosing, fixing stone, washing and absorbing chippings, taking the chippings, etc. and has important clinical application value.

Description

cystoscopy technical field The invention relates to an apparatus for treating calculi in the body, in particular to a stone-extracting mirror for bladder and kidney pelvis. Background technique Stones in the body, such as bladder and renal pelvis stones, are a common condition. Clinically, intracavitary minimally invasive techniques are often used for lithotripsy of bladder and renal pelvis stones. At present, the existing bladder lithotripsy adopts the principle of mechanical mechanics, and crushes the stones through the mechanical extrusion of the occlusal force of the lithotripsy forceps. However, it is difficult to crush the stones during operation, and it is also difficult to remove the stones after crushing the stones, and it is easy to damage the bladder and urethral mucosa in the process of crushing the stones. At the same time, the current bladder lithotripsy does not have the functions of fixing stones, providing a passage for crushed stones, flushing and abso...

AI Technical Summary

Problems solved by technology

However, due to the defects in the design and structure of bladder and ureter foreign body forceps, the function is single, and only small foreign bodies and gravel can be ingested.

It cannot be used for intraoperative fixation of stones, lithotripsy, and lithotripsy, so it has limited use in intracavitary minimally invasive lithotripsy

When the existing lithotripsy technology is used to treat bladder and renal pelvis stones, the stones cannot be fixed during the operation, and the stones are easy to slide in the bladder and renal pelvis, which brings difficulties to the lithotripsy operation. After the lithotripsy, there is no effective means to remove the stones in time

These problems have seriously affected the curative effect of minimally invasive surgery in the treatment of bladder and renal pelvis stones
