A percutaneous renal ultra-micro channel visual puncture and expansion integrated kit with negative pressure suction

Abstract

The invention provides a percutaneous renal ultra-micro channel visual puncture and expansion integrated kit with negative pressure suction, comprising: a sheath tube, the sheath tube has an inner open end at the distal end of the sheath tube, and a proximal end of the sheath tube The outer open end, the sheath tube is provided with a mutually independent negative pressure channel and a perfusion channel, and the negative pressure channel and the perfusion channel are separated by a partition wall; the expansion pipe joint is connected to the outer open end of the proximal end of the sheath tube , a catheter device is arranged on the expansion tube joint, and the catheter device can perfuse flushing water or operating instruments into the perfusion channel; a negative pressure output device is connected to the outer open end of the proximal end of the sheath, and the negative pressure output The device is in sealed communication with the negative pressure channel. Through the improvement of the sheath tube structure, the invention can meet the functional requirements of liquid injection and stone suction, ensure a wide field of vision and clear images, and can also absorb and discharge larger stone fragments, avoid repeated work, and reduce operation time. , improve the efficiency of surgery and reduce the work intensity of doctors.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a percutaneous renal ultra-micro channel visual puncture and expansion integrated kit with negative pressure suction. Background technique [0002] Kidney stones are one of the most common diseases in urology. Percutaneous nephroscopic surgery is a minimally invasive technique widely used in the treatment of kidney stones. Surgical method for performing lithotripsy. [0003] In the past 20 years, domestic and foreign scholars have made unremitting efforts for the minimally invasive percutaneous renal channel, and designed a series of minimally invasive PCNL, including minimally invasive percutaneous nephrolithotomy (mini-mally invasive PCNL). , MPCNL), Chinese MPCNL (Chinese MPCNL), ultra-fine percutaneous nephrolithotomy (ultra-mini-PCNL, UMP), micro-channel percutaneous nephrolithotomy (Micro-PCNL) and so on. In practice, people gradually realize that there are problems ...

AI Technical Summary

Problems solved by technology

Although ultra-micro-channel percutaneous nephrolithotomy (super-mini-PCNL, SMP) with a perfusion negative pressure suction system can better solve the problems of insufficient perfusion, unclear vision, and high internal pressure of the renal pelvis, SMP is only suitable for Management of kidney stones <2.5 cm in diameter

[0004] In addition, when traditional percutaneous nephroscopic surgery enters the kidney due to puncture, the operator relies on hand feeling, or predicts the depth under the guidance of ultrasound, CT, etc. to judge the puncture site. These methods are blind, time-consuming, and occasionally Mistakes can easily lead to bleeding, residual stones, sepsis and other complications
