Ureteral soft diameter introduction sheath with real-time pressure display and suction ability

Abstract

The invention relates to a flexible ureteroscope leading-in sheath with real-time internal-cavity pressure detecting and sucking functions. The flexible ureteroscope leading-in sheath comprises a suction joint, a sealing cover, a suction pipeline, a flexible ureteroscope sheath pipeline, a pressure sensor and a signal circuit. A perfusion pressure sensing passageway is formed in the side walls of the suction joint and the flexible ureteroscope sheath pipeline, a pressure sensing module is fixed on the sidewall of the suction joint and comprises the pressure sensor, a pressure sensor circuit, a signal processing unit and a signal output unit, the signal processing unit is connected with the pressure sensing passageway, the pressure sensor circuit is arranged in the pressure sensing passageway, the pressure sensor connected to the tail end of the pressure sensor circuit is positioned at the tail end of the pressure sensing passageway, and a pressure dispersing hole is formed at the tail end of the flexible ureteroscope sheath pipeline and communicated with the pressure sensing passageway. The flexible ureteroscope leading-in sheath integrates an alarming function, a real-time displaying function and a pressure detecting function and is convenient for medical staff to observe operation states in real time; when the flexible ureteroscope leading-in sheath is operated in the flexible ureteroscope sheath pipeline, internal pressure of an organ can be sensed, a patient can be protected from being harmed by overlarge pressure, and septicopyemia can be restrained particularly.

Description

technical field [0001] The invention relates to an accessory device for intracavity surgery of a human body, in particular to a flexible ureteral introduction sheath with real-time detection of intracavity pressure and adsorption capacity. Background technique [0002] The flexible ureteroscope guide sheath is mainly used clinically for ureteral stenosis, adhesion, obstruction, obstruction, and calculus, and relevant operations are required for treatment to establish a surgical channel, through which the endoscope, laser fiber, stone removal device or operating cable are introduced. Wait. [0003] In the prior art, Chinese utility model patent 200810197442.4 relates to a combined flexible and rigid ureteroscope, including a cylindrical hard sheath, a flexible mirror, a handle and a swivel joint, and a sleeve fixedly connected to the flexible mirror outside the rear section of the flexible mirror. The fixed sleeve of the soft mirror, the fixed sleeve of the soft mirror and t...

AI Technical Summary

Problems solved by technology

[0004] The common defect of the ureteral introduction sheath in the above-mentioned prior art is that the pressure cannot be measured, and it is easy to cause sepsis due to excessive intracavity pressure, so there is a need for further improvement
