AI Technical Summary

Technical Problem

During surgery such as ureteroscopic stone lithotripsy, the prior art pressure sensor is fixed at the end of the sheath pipe, which easily encroaches on the surgical channel, and has the risk of shedding and error, making it difficult to detect the pressure in the human body in real time and accurately.

Method used

A ureter guide sheath with pressure measurement function was designed. By opening a cavity on the sheath tube and placing an optical fiber pressure sensor, it is independent of the surgical channel, avoiding collision and encroachment with surgical instruments, while improving the accuracy and anti-interference ability of the sensor. .

Benefits of technology

Real-time and accurate detection of renal pressure during the operation is achieved, reducing the risk of surgery, avoiding sensor shedding and errors, and improving detection accuracy and speed.

Abstract

The utility model discloses a ureter guiding sheath with a pressure measuring function. The ureter guiding sheath comprises a sheath tube and an expander, the dilator comprises a dilation tube and a dilation tube connector which are connected with each other, the rear end of the sheath tube is connected with a guide sheath connector, a middle channel of the sheath tube is an operation channel, meanwhile, a cavity channel with the same length as the sheath tube is further formed in the sheath tube, and an optical fiber pressure sensor is placed in the cavity channel and used for measuring in-vivo pressure. According to the ureter guiding sheath with the pressure measuring function, the optical fiber sensor has an independent detection space through the cavity channel with the hole formed in the end face of the sheath guiding tube, an operation cannot be hindered or influenced, the falling phenomenon cannot occur, and the safety of a patient is guaranteed. And meanwhile, the used optical fiber sensor has ultrahigh precision, high signal strength, electromagnetic interference resistance and atomic radiation resistance, and is not easily influenced by environmental and physical factors, so that the pressure data detection precision is higher, and the speed is higher.
