Description

Bladder and renal pelvis

Technical field

The invention relates to a device for treating stones in the body, in particular to a bladder renal pelvis stone.

Background technique

Stones in the body, such as bladder and renal pelvis, are a common disease. Clinically, intracavitary minimally invasive techniques are used for the treatment of bladder and renal calculi.

At present, the existing bladder lithotripsy adopts the mechanical mechanics principle, and the stone is crushed by mechanical crushing of the crushing force of the gravel. However, it is difficult to crush the stone during the operation, and it is difficult to remove the stone after the stone is crushed, and it is easy to damage the bladder and the urethra mucosa during the process of crushing the stone. At the same time, the current bladder lithotriposcope does not have the function of fixing stones, providing gravel passages, flushing gravel, ingesting gravel and continuous flushing, so it is rarely used clinically.

Various ureteroscopes and nephroscopes are available for the treatment of bladder stones and renal pelvis stones. They can provide operational access for pneumatic ballistic lithotripsy or laser lithotripsy. However, there is no effective method for crushing stones after crushing stones. Take it out and do not rinse it continuously during the operation.

The existing various bladder and ureteral foreign body forceps are mainly used for ingesting foreign bodies, and can also be used for intraoperative stone removal. However, due to the structural defects of the bladder and ureteral forceps, the effect is single, and only small foreign bodies and debris can be ingested. Can not be used for intraoperative fixation of stones, can not be used for gravel operation, can not absorb the stone, so the use of minimally invasive surgery in the cavity is limited.

When the existing gravel technique is used to treat bladder and renal pelvis stones, the stones cannot be fixed during the operation. The stones are easy to slide in the bladder and the renal pelvis, which brings difficulties to the operation of the gravel. After the gravel, there is no effective means to remove the gravel in time. These problems have seriously affected the efficacy of minimally invasive surgery for the treatment of bladder and renal pelvis. Therefore, there is a need in the clinic for a hand that can be used for intravesical minimally invasive lithotripsy to fix the bladder and renal pelvis stones, and then to crush the stones. After the stones are crushed, the stones can be washed and the gravel is taken. Equipment.

Summary of invention
