Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pressure valve for adjusting the automatic water discharge and decompression of the renal pelvis pressure. Background Technique

[0002] Sepsis is one of the most serious complications after ureteroscopy. Compared with patients without sepsis, the medical costs associated with sepsis after ureteroscopy are much higher. Sepsis after ureteroscopy has also been shown to significantly increase the all-cause mortality of patients. The pressure within the renal collecting system, also known as the intrarenal pressure (IRP), ranges from 0 to 6 mm Hg at baseline, but can increase significantly during endoscopic surgery. Higher IRP can lead to complications such as pain, infection, and even kidney injury. The main causes of elevated IRP are considered to be the type of irrigation used and the presence or absence of a ureteral access sheath. It has been shown that when using a UAS of size 12 / 14Fr or 14 / 16Fr, the UAS can reduce IRP. Many studies have determined that an IRP above 40 mmHg will result in pyelovenous backflow, which theoretically increases the risk of urosepsis and pain. Pain also occurs after ureteroscopy even without intraoperative complications.

[0003] However, measuring IRP during ureteroscopy is cumbersome, and pressure-sensing wires can be used in patients with pre-existing nephrostomy tubes during ureteroscopy, but these wires also require additional monitors and the insertion of additional equipment into the ureter. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pressure valve for adjusting the automatic water discharge and decompression of the renal pelvis pressure, which can prevent the occurrence of complications due to excessive intrarenal pressure in patients during endoscopic surgery, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pressure valve for adjusting the automatic water discharge and decompression of the renal pelvis pressure, including an exploration component, an external connection component, and a connection component. The exploration component is used for viewing during endoscopic surgery. The external connection component is arranged on the exploration component for inserting and docking external instruments. The connection component is arranged on the exploration component for docking external imaging equipment. The external connection component includes an installation tube, two pressure valves, an instrument insertion tube, and a soft material insertion tube. The installation tube is arranged on the exploration component. Both of the two pressure valves are fixedly installed on the installation tube. The instrument insertion tube is fixedly installed on the outer wall of the installation tube. The soft material insertion tube is fixedly installed on the outer wall of the installation tube.

[0006] Furthermore, the two pressure valves are arranged symmetrically left and right, and the two pressure valves are arranged with left inlet and right outlet.

[0007] Further, the exploration component includes a mounting base, a lens body, and a lens. The lens body is fixedly mounted on the mounting base, the lens is fixedly mounted on one end of the lens body, and the mounting tube is fixedly connected to the mounting base.

[0008] Further, a triangular connection block is fixedly mounted on the outer wall of the mounting base, and the inclined surface of the triangular connection block away from the mounting tube is arc-shaped.

[0009] Further, the connection component includes an optical fiber interface, a connecting rod, and an adapter interface. The optical fiber interface is fixedly mounted on the mounting base, the connecting rod is fixedly mounted on the triangular connection block, and the adapter interface is fixedly mounted on the connecting rod.

[0010] Further, pressure sensors are fixedly mounted on both of the pressure valves.

[0011] In summary, due to the adoption of the above technology, the beneficial effects of the present utility model are as follows:

[0012] By providing an external component, liquid hoses are inserted on both of the pressure valves, and pressure adjustment is performed on the two pressure valves. The pressure adjustment is less than 40 mmHg. Water is injected into the pressure valves through an external water injection device, and the water is injected into the patient's ureter. The injected water is discharged through the pressure valves. When the drainage pressure of the pressure valves exceeds the threshold value of 40 mmHg, the pressure valves are adjusted to reduce the pressure at this time, achieving the purpose that the water output is greater than the water input. It has the advantage of preventing complications caused by too high renal pressure in the patient during endoscopic surgery.

[0013] By providing a connection component, an external optical fiber cable is docked and inserted with the optical fiber interface, and the connection cable of the imaging device is picked up and docked and inserted with the adapter interface. More specifically, through the optical fiber interface and the adapter interface, the image seen by the lens is transmitted to an external imaging device, which has the advantage of transmitting images and facilitating medical staff to observe in a timely manner.
