A ureteral introduction sheath with real-time pressure detection and adsorption capacity

Abstract

The invention relates to an accessory device for organ intracavity operations, in particular to a ureter lead-in sheath with real-time pressure detection and absorption capacity. The ureter lead-in sheath comprises a pouring connector, a sealing cover, a suction pipeline, a pressure sensing passageway and a ureter sheath pipeline. The sealing cover is arranged at one end of the pouring connector. The ureter sheath pipeline is arranged at the other end of the pouring connector. The suction pipeline is arranged on the side face of the pouring connector and is communicated with a pouring passageway in the pouring connector. A pouring pressure sensing passageway is arranged in the side walls of the pouring connector and the ureter sheath pipeline. The portion, on one side of the pouring connector, of the pouring pressure sensing passageway is connected with the pressure detection connector which can be connected with an external pressure sensor. A pressure coupling hole is formed in the portion, on one side of the ureter sheath pipeline, of the tail end of the pouring pressure sensing passageway. The ureter lead-in sheath is easy to implement and convenient to operate and use; when a sheath pipeline works, pressure inside organ cavities can be detected all the time through the pressure detection passageway, it is avoided that patients are damaged when the intracavity pressure is too large, and the ureter lead-in sheath is suitable for popularization.

Description

technical field [0001] The invention relates to an accessory device for intracavity surgery of a human body, in particular to a 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] Chinese utility model patent 200810197442.4 relates to a combined flexible and rigid ureteroscope, including a cylindrical hard sheath, a flexible scope, a handle and a rotary joint, and a flexible scope fixed sleeve fixedly connected with the flexible scope is covered outside the rear section of the flexible scope , the fixed sleeve of the soft mirror and the soft mirror are inserted into...

Problems solved by technology

However, in practical applications, due to the small diameter of the sheath tube (generally less than 4mm), and the pressure sensor due to its size, waterproof and other reasons, the current level of technology and technology cannot really be realized. At the same time, considering that the method of directly installing the sensor at the end cannot Avoid the sensor falling out of the cavity due to accidental factors during the operation, causing surgical risks
