Description

Technical Field

[0001] This utility model relates to an auxiliary device, specifically an auxiliary device for urological surgery. Background Technology

[0002] Percutaneous nephrolithotomy (PCNL), an important urological treatment for kidney stones, is widely used in clinical practice due to its unique advantages. This procedure involves creating a channel from the skin to the kidney in the lower back, inserting a nephroscope into the kidney, and using advanced lithotripsy tools such as lasers and ultrasound to precisely break up and remove the kidney stones. Compared to traditional open surgery, PCNL has significant advantages such as less trauma, less pain, more thorough stone removal, and faster recovery, providing patients with a better treatment experience and better recovery outcomes.

[0003] However, during percutaneous nephrolithotomy, medical staff need to continuously irrigate the surgical site with fluids such as saline to maintain a clear surgical field. Currently, the disordered flow of this irrigation fluid severely impacts the collection of stone samples. During the procedure, broken stones scatter with the irrigation fluid, making accurate collection extremely difficult. This not only increases the time and effort required for sample collection but may also lead to the omission of some stones, affecting the accurate analysis of their composition and consequently negatively impacting the diagnosis and treatment planning. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an auxiliary device for urological surgery, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes:

[0006] A disc with several circular grooves evenly arranged on its circumference;

[0007] Multiple cylinders are slidably connected in the circular groove, and a limit ring is fixed at the bottom end of each cylinder. A spring is sleeved on the outer circumference of the cylinder above the limit ring.

[0008] A circular ring is disposed at the end of the cylinder that extends above the disk, and a plurality of insert posts are arranged in a circumferential array on the lower surface of the circular ring;

[0009] A rotating shaft is rotatably connected to the center of the top of the disk.

[0010] A liquid receiving hopper is fixed to the top of the rotating shaft, and a drain pipe is provided on one side of its bottom. A control valve is installed on the drain pipe.

[0011] The guide surface is inclinedly disposed inside the liquid receiving hopper, and its bottom end extends to the inlet of the drain pipe.

[0012] Preferably, the diameter of the ring is larger than the outer diameter of the cylinder, and the axial length of the insert is in the range of 10-30mm.

[0013] Preferably, the upper end of the spring abuts against the bottom surface of the disc, and the lower end abuts against the top surface of the limiting ring, so that the cylinder has a downward tendency in its natural state.

[0014] Preferably, the guiding surface is a conical inclined surface that slopes from the center of the liquid inlet toward the drain pipe, with an inclination angle of 5°-15°.

[0015] Preferably, the axial extension direction of the cylinder is perpendicular to the surface of the disk, and each cylinder can move independently along the axial direction.

[0016] Preferably, the control valve is a plug valve or a butterfly valve, and is located in the middle section of the drain pipe.

[0017] Beneficial effects: The filter bag is fixed stably and has strong adaptability: The filter bag can be inserted and positioned by the insert on the ring, and the cylinder can drive the ring and the filter bag to maintain a stable position under the downward force of the spring, which can adapt to filter bags of different weights and pressures and ensure that the filter bag is fixed firmly.

[0018] Facilitates stone separation and testing: The filter bag effectively filters the irrigation fluid generated during surgery, removing the fluid while retaining the stones, thus separating them from the irrigation fluid. When stones need to be sent for testing, the control valve can be closed, the drain pipe rotated to the unused filter bag's cylindrical position, and the control valve reopened to resume the filtration process. This allows for quick and convenient operation without interrupting the irrigation process.

[0019] Highly efficient liquid guidance: The inclined guiding surface inside the receiving hopper (a conical inclined surface that slopes from the center of the receiving hopper toward the drain pipe at an angle of 5°-15°) can effectively guide the liquid in the receiving hopper to the drain pipe for easy discharge, thus achieving highly efficient liquid guidance.

[0020] Precise liquid discharge control: The control valve (plug valve or butterfly valve) installed on the drain pipe is located in the middle of the drain pipe. By operating the control valve, the flow of liquid in the drain pipe can be easily controlled, achieving precise control of liquid discharge.

[0021] High practicality and adaptability: The design of the ring and the insertion post makes it easy to put the filter bag on the ring and insert and position the filter bag, which increases the practicality and adaptability of the device. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0029] Example 1, by Figure 1-4 This invention provides an auxiliary device for urological surgery, comprising:

[0030] Disk 1: Several circular grooves 2 are evenly arranged on its circumference; Disk 1 serves as the basic supporting component of the entire device, providing a stable platform for the installation and operation of other components.

[0031] Cylinder 3: Multiple cylinders 3 are slidably connected within the circular groove 2. Each cylinder 3 has a limit ring 4 fixed at its bottom end, and a spring 5 is fitted around the outer circumference of the cylinder 3 above the limit ring 4. The cylinder 3 can slide up and down within the circular groove 2, and the spring 5 provides a downward force to the cylinder 3, giving it a tendency to move downwards in its natural state.

[0032] Ring 6: Located at the end of the cylinder 3 extending above the disk 1, the lower surface of ring 6 has several inserts 7 arranged in a circumferential array. The diameter of ring 6 is larger than the outer diameter of cylinder 3, and the axial length of inserts 7 ranges from 10-30mm. The design of ring 6 and inserts 7 is mainly for inserting and positioning filter bags by inserting them onto ring 6, thereby increasing the practicality and adaptability of the device.

[0033] Rotating shaft 8: Rotatably connected to the center of the top of the disc 1. The rotating shaft 8 allows the liquid receiving container 9 to rotate relative to the disc 1, making it easy to adjust the position of the liquid receiving container 9 to adapt to different surgical needs.

[0034] Liquid receiving hopper 9: Fixed to the top of the rotating shaft 8, with a drain pipe 10 on one side of its bottom, and a control valve 11 installed on the drain pipe 10. The liquid receiving hopper 9 is used to collect irrigation fluid generated during surgery. A guide surface 12 is inclined inside the liquid receiving hopper 9, with its bottom end extending to the inlet of the drain pipe 10. The guide surface 12 is a conical inclined surface that slopes from the center of the liquid receiving hopper 9 towards the drain pipe 10 at an angle of 5°-15°. The guide surface 12 effectively guides the fluid in the liquid receiving hopper 9 to the drain pipe 10 for easy discharge.

[0035] Control valve 11: Control valve 11 is a plug valve or butterfly valve, located in the middle section of the drain pipe 10. By operating control valve 11, the flow of liquid in the drain pipe 10 can be easily controlled, achieving precise control of liquid discharge.

[0036] Cooperation between components

[0037] When the filter bag needs to be fixed to the device, it can be connected through the insert 7 on the ring 6. Under the action of the spring 5, the cylinder 3 can fix the filter bag through the ring 6 and the insert 7 according to the weight and pressure of the connected equipment, which facilitates the fixation of the filter bag.

[0038] During the procedure, the fluid generated flows into the receiving hopper 9 and, guided by the guide surface 12, flows towards the drain pipe 10. By operating the control valve 11, the fluid in the receiving hopper 9 can be drained in a timely manner, maintaining the normal working condition of the receiving hopper 9. At the same time, the receiving hopper 9 can rotate relative to the disc 1 via the rotating shaft 8, making it easy to adjust the fluid receiving position.

[0039] Working principle: In the application of this invention, before surgery, the filter bag is first passed through the inside of the cylinder 3 and the bag opening is placed on the ring 6. The filter bag opening is then inserted and positioned using the insert post 7. At this time, since multiple cylinders 3 are slidably connected in the evenly arrayed circular grooves 2 on the circumference of the disc 1, and each cylinder 3 has a limiting ring 4 fixed at its bottom end, and a spring 5 is fitted around the outer circumference of the cylinder 3 above the limiting ring 4, the cylinder 3 drives the ring 6 and the fitted filter bag to maintain a stable position under the downward force of the spring 5. This allows it to adapt to filter bags of different weights and pressures, ensuring that the filter bag is firmly fixed.

[0040] During the procedure, the generated flushing fluid first enters the receiving hopper 9, and then flows through the drain pipe 10 at the bottom of the receiving hopper 9 to the filter bag inside the corresponding cylinder 3. The filter bag filters out the flushing fluid, leaving the stones, ensuring effective collection of fluid and separation of the stones. When it is necessary to send the stones in the corresponding filter bag for testing, close the control valve 11, turn the drain pipe 10 to the position of the unused filter bag cylinder 3, and open the control valve 11 to start the filtration operation again without stopping the flushing operation.

[0041] Liquid flowing into the receiving hopper 9 is guided towards the drain pipe 10 by the inclined guide surface 12 inside the hopper. The guide surface 12 is a conical inclined surface that slopes from the center of the receiving hopper 9 towards the drain pipe 10 at an angle of 5°-15°. This design can efficiently guide the liquid. A control valve 11 is installed on the drain pipe 10. The control valve 11 is a plug valve or a butterfly valve and is located in the middle section of the drain pipe 10.

[0042] Beneficial effects: The filter bag is fixed stably and has strong adaptability: The filter bag can be inserted and positioned by the insert 7 on the ring 6, and the cylinder 3 can drive the ring 6 and the filter bag to maintain a stable position under the downward force of the spring 5, adapting to filter bags of different weights and pressures, and ensuring that the filter bag is fixed firmly.

[0043] Facilitates stone separation and testing: The filter bag effectively filters the irrigation fluid generated during surgery, removing the irrigation fluid while retaining the stones, thus separating them from the irrigation fluid. When it is necessary to send the stones for testing, the control valve 11 can be closed, the drain pipe 10 can be rotated to the unused filter bag cylinder 3 position, and the control valve 11 can be reopened to restart the filtration operation without stopping the irrigation process, making it convenient and quick.

[0044] Highly efficient liquid guidance: The guide surface 12 (a conical inclined surface that slopes from the center of the liquid receiving hopper 9 toward the drain pipe 10 at an angle of 5°-15°) inside the liquid receiving hopper 9 can effectively guide the liquid in the liquid receiving hopper 9 to the drain pipe 10 for easy discharge, thus achieving highly efficient liquid guidance.

[0045] Precise liquid discharge control: The control valve 11 (plug valve or butterfly valve) installed on the drain pipe 10 is located in the middle section of the drain pipe 10. By operating the control valve 11, the flow of liquid in the drain pipe 10 can be easily controlled, so as to achieve precise control of liquid discharge.

[0046] High practicality and adaptability: The design of the ring 6 and the insertion post 7 makes it easy to put the filter bag on the ring 6 and insert and position the filter bag, which increases the practicality and adaptability of the device.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
