Description

Technical Field

[0001] This utility model relates to the field of flexible ureteroscope technology, specifically a pressure-measuring flexible ureteroscope. Background Technology

[0002] Traditional flexible ureteroscopes cannot measure changes in renal pelvis pressure. If the renal pelvis pressure is too high, exceeding the safe threshold of 30 mmHg, it can cause serious medical accidents such as renal pelvis tissue swelling and necrosis. If the negative pressure suction is too strong, it can cause the renal pelvis space to collapse, resulting in a narrow space inside the renal pelvis, blurred vision, and inability to find the stone. It can even cause renal pelvis tissue necrosis, leading to surgical failure.

[0003] Based on this, the present invention provides a pressure-measuring flexible ureteroscope to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-measuring flexible ureteroscope to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model proposes a pressure-measuring flexible ureteroscope, comprising a main tube, a data transmission interface installed at the end of the main tube, a distal bending knob installed on the main tube on one side of the data transmission interface, a pressure measuring interface and a working channel interface respectively installed at both ends of the main tube on the side of the data transmission interface and the distal bending knob, a head end assembly installed at the top of the main tube, and a distal flexible section installed on the main tube on one side of the head end assembly.

[0006] Preferably, the head-end assembly further includes a lens module, LED lights, pressure measuring holes, and a working channel. The working channel is located inside the head-end assembly, with the lens module located at the top of the working channel. LED lights are located on both sides of the lens module, and several evenly arranged pressure measuring holes are located on the outer side of the head-end assembly.

[0007] Preferably, the LED light and the data transmission interface are electrically connected.

[0008] Preferably, the head assembly is made of polyurethane.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention allows for real-time monitoring of renal pelvis pressure during ureteroscopic surgery. Medical staff can adjust the perfusion flow rate and negative pressure suction pressure promptly based on the pressure readings to prevent damage from excessive intrarenal pressure. Simultaneously, by increasing the perfusion flow rate and negative pressure suction pressure within the controlled intrarenal pressure range, water circulation can be accelerated, thereby improving stone removal efficiency. Furthermore, this method only requires one channel for pressure monitoring on the flexible endoscope, resulting in a simple structure. Compared to methods with sensors placed at the tip, this reduces the risk of sensor malfunction due to poor sealing or fluid leakage. The rear-mounted sensor is also more economical. In summary, this method conveniently obtains real-time intrarenal pelvis pressure during laser lithotripsy and negative pressure stone suction. Medical staff can manually adjust the perfusion and negative pressure devices to maintain intrarenal pelvis pressure within a safe range, significantly improving surgical safety, increasing stone removal efficiency, and shortening surgical time.

[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0013] Please see Figures 1 to 2 This utility model proposes a pressure-measuring flexible ureteroscope, including a main tube 7, a data transmission interface 5 installed at the end of the main tube 7, a distal bending adjustment knob 4 installed on the main tube 7 on one side of the data transmission interface 5, a pressure measuring interface 1 and a working channel interface 2 respectively installed at both ends of the main tube 7 on the side of the data transmission interface 5 and the distal bending adjustment knob 4, a head end assembly 3 installed at the top of the main tube 7, and a distal flexible section 6 installed on the main tube 7 on one side of the head end assembly 3.

[0014] It should be noted that the head-end assembly 3 also includes a lens module 301, an LED light 302, a pressure measuring hole 303, and a working channel 304. The working channel 304 is located inside the head-end assembly 3. The lens module 301 is located at the top of the working channel 304. LED lights 302 are located on both sides of the lens module 301. Several evenly arranged pressure measuring holes 303 are located on the outside of the head-end assembly 3. The LED lights 302 are electrically connected to the data transmission interface 5. The head-end assembly 3 is made of polyurethane material.

[0015] In practical applications, such as Figure 1 As shown, the pressure-measuring flexible ureteroscope consists of a handle section and a catheter section. The handle section includes a pressure measurement interface 1, a working channel interface 2, a distal bending knob 4, and a data transmission interface 5; the catheter section includes a main tube 7, a distal flexible section 6, and a tip assembly 3; as shown... Figure 2 The head-end assembly 3 shown includes a lens module 301, an LED light 302, a pressure measuring hole 303, and a working channel 304. The pressure measuring interface 1 and the pressure measuring hole 303 are separate pathways for pressure measurement. The pressure measuring hole 303 can be located at any position from the head end to the rear section 10 cm. The lens module 301, the LED light 302, and the data transmission interface 5 are connected for image data transmission. The working channel interface 2 and the working channel 304 form a pathway for the passage of instruments such as optical fibers and baskets, as well as for the infusion of physiological saline. The distal bending knob 4 controls the bending of the distal flexible section 6 by controlling the bending wire inside the tube.

[0016] In a specific implementation, during practical application, a separate channel from the pressure measuring connector 1 connects to the pressure measuring port 303 at the distal end of the catheter. Before use, the working channel 304 is filled with physiological saline through the pressure measuring connector 1. Then, the pressure measuring connector 1 is connected to the pressure sensor connector on the main unit, and the pressure is zeroed. During ureteroscopic surgery, the intrarenal pelvis pressure can be monitored in real time and displayed on the main unit, facilitating medical staff to obtain intrarenal pressure information. This allows for adjustment of perfusion flow and negative pressure parameters to ensure that the intrarenal pressure remains within a safe threshold while simultaneously increasing the stone clearance efficiency of the surgery with appropriate perfusion flow and negative pressure parameters.
