Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an electronic flexible ureteroscope with integrated suction stone removal function. Background Technology

[0002] A flexible ureteroscope is a medical device that uses electronic imaging (such as CMOS / CCD sensors) to perform endoscopic functions. Its scope can be rigid or flexible, but in clinical applications it usually refers to a flexible electronic ureteroscope.

[0003] During surgery, after the flexible endoscope locates the stone, a holmium laser fiber is introduced through the working channel to break the stone. The suction tube is then inserted through the working channel of the flexible endoscope to process the broken stone. This method reduces the efficiency of the device in removing stones. In addition, the built-in suction tube is always open when inserted, and the liquid used to clean the camera flows into the suction tube, causing the camera surface to become blurry and affecting the performance of the flexible endoscope.

[0004] To address the above issues, a flexible ureteroscope integrating suction stone removal function is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible ureteroscope with integrated suction stone removal function. By using this device, the problems mentioned in the background can be solved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible ureteroscope with integrated suction stone removal function, comprising a base, a tube fixedly installed on the other side of the base, several cameras fixedly installed on the other side of the tube, a laser head installed on the other side of the tube, a connecting water pipe fixedly installed near the middle of the rear side of the base, a suction tube fixedly installed near the middle of the front side of the base, a collection tube threadedly connected to the outer circumference of the suction tube, an anti-blocking component provided on the outer circumference of the collection tube, a collection component provided in the inner cavity of the collection tube, several laser heads passing through one side of the tube, a connecting ring fixedly installed at the end of the laser heads, an adjustment component provided on the other side of the connecting ring, and a fixed tube inserted into one side of the connecting ring, one end of the fixed tube being inserted into the connecting water pipe, a circular tube movably passing through one side of the connecting ring, and the other end of the circular tube being fixedly connected to the tube, one end of the circular tube being inserted into the suction tube;

[0007] The adjustment assembly includes a servo motor fixedly installed on one side of the connecting ring near the bottom. A drive gear is fixedly installed on the power output shaft of the servo motor. Driven gears mesh on both the front and rear sides of the drive gear. A round rod and a movable rod pass through one side of the driven gear, and both the round rod and the movable rod are rotatably connected to the connecting ring. A take-up roller A is fixedly installed at the ends of both the movable rod and the round rod. A connecting rope is wound around the outer circumference of the take-up roller A. A binding strap is fixedly installed at the ends of the connecting ropes, and the binding strap is located on the outer circumference of the round tube.

[0008] Furthermore, a straight rod and a support rod are fixedly installed on one side of the connecting ring near the front and rear sides, respectively. A take-up roller B is fixedly installed at the end of both the straight rod and the support rod, and the connecting rope is located on the outer periphery of the adjacent take-up roller B.

[0009] Furthermore, the collection assembly includes a filter screen fixedly installed in the inner cavity of the collection tube near the middle position, and grooves A, B and C are provided at the bottom of the inner cavity of the collection tube, which are arranged linearly from left to right.

[0010] Furthermore, the depths of groove A, groove B, and groove C are 0.2, 0.4, and 0.6 cm, respectively.

[0011] Furthermore, the anti-clogging component includes a movable ring located near one side of the inner cavity of the collection tube, a striking rod fixedly installed on the other side of the movable ring near the top and bottom, a limiting ring A fixedly sleeved on the outer periphery of the collection tube near one end, a limiting ring B fixedly sleeved on the outer periphery of the collection tube near the other end, and a sliding seat fixedly installed on the top and bottom of the collection tube, with a sliding ring slidably connected to the opposite side of the sliding seat.

[0012] Furthermore, a limiting rod extends through one side of the movable ring near the top, and one end of the limiting rod is fixedly connected to the movable ring.

[0013] Furthermore, the sliding ring and the moving ring have opposite magnetic properties, and the striking rods are both made of rubber.

[0014] Furthermore, a reset telescopic rod is fixedly installed on both sides of the limiting ring B and the limiting ring A near the front and rear sides, and a reset spring is movably sleeved on the outer periphery of the reset telescopic rod, and the two ends of the reset spring are fixedly connected to the sliding ring and the limiting ring B respectively.

[0015] Furthermore, each of the sliding seats has a sliding groove in its inner cavity, and each sliding groove has a sliding block slidably connected to its inner cavity, with the opposite side of each sliding block being fixedly connected to a sliding ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When the tube is inserted into the body, the two take-up rollers A can rotate with the help of the adjusting components, which can wind up the connecting rope and tighten the restraint strap, keeping the round tube in a sealed state. This prevents liquid from entering the inner cavity of the round tube during the camera rinsing process, which would affect the cleaning of the camera and reduce the effectiveness of the device.

[0019] 2. During stone suction, a filter screen can be used to isolate the stones on the other side of the screen. Furthermore, by using tanks of varying heights and depths, the system's capture capacity is greatly increased, avoiding the problem of a single filter screen easily becoming clogged.

[0020] 3. When the filter screen becomes clogged, the sliding ring can be moved by the magnetic force, and the tapping rod fixed on the moving ring can tap the filter screen to shake off the stones blocking the filter screen, thus preventing clogging, affecting the suction force of the collection tube and reducing the efficiency of the operation.

Therefore, they should not be construed as limitations on this invention.

[0033] like Figure 1 - Figure 9As shown, a flexible ureteroscope with integrated suction stone removal function includes a base 1, a tube 5 fixedly installed on the other side of the base 1, several cameras 30 fixedly installed on the other side of the tube 5, a laser head 40 installed on the other side of the tube 5, a connecting water pipe 2 fixedly installed on the rear side of the base 1 near the middle position, and a suction tube 3 fixedly installed on the front side of the base 1 near the middle position (the outer periphery of the suction tube 3 has an external thread near the rear end). A collection tube 4 is threadedly connected to the outer periphery of the suction tube 3 (the end of the collection tube 4 is connected to an external suction device). An anti-blocking component 6 is provided on the outer periphery of the collection tube 4, and a collection component 8 is provided in the inner cavity of the collection tube 4. One side of the tube 5... Several laser heads 40 are installed throughout (the laser heads 40 can crush stones). A connecting ring 9 is fixedly installed at the end of the laser heads 40. An adjustment component 7 is provided on the other side of the connecting ring 9. A fixed tube 10 is inserted into one side of the connecting ring 9 (connected to the fixed tube 10 via a connecting water pipe 2, which can flush water onto the stone area to fill it with water, clean the camera 30, and facilitate clear images during the subsequent crushing process). One end of the fixed tube 10 is inserted into the connecting water pipe 2. A round tube 20 (a flexible elastic tube) is movably inserted through one side of the connecting ring 9. The other end of the round tube 20 is fixedly connected to the tube body 5. One end of the round tube 20 is inserted into the suction tube 3.

[0034] To avoid affecting the cleaning of camera 39, in this embodiment, as follows: Figure 5 and Figure 6 As shown, the adjustment assembly 7 includes a servo motor 71 fixedly installed on one side of the connecting ring 9 near the bottom. A drive gear 72 is fixedly installed on the power output shaft end of the servo motor 71. Driven gears 73 are meshed on both the front and rear sides of the drive gear 72. A round rod 77 and a movable rod 78 pass through one side of the driven gear 73, and both the round rod 77 and the movable rod 78 are rotatably connected to the connecting ring 9. A take-up roller A74 is fixedly installed at the ends of both the movable rod 78 and the round rod 77. A connecting rope 75 is wound around the outer periphery of the take-up roller A74. A binding strap 76 is fixedly installed at the ends of the connecting rope 75, and the binding strap 76 is located on the outer periphery of the round tube 20.

[0035] Specifically, when the tube 5 is inserted into the body, the two take-up rollers A74 can rotate with the help of the adjusting component 7, which can take up the connecting rope 75 and tighten the restraint strap 76, so that the round tube 20 is in a sealed state. This can prevent all the liquid from entering the inner cavity of the round tube 20 during the rinsing process of the camera 30, which would affect the cleaning of the camera 30 and reduce the effectiveness of the device.

[0036] A straight rod 751 and a support rod 753 are fixedly installed on one side of the connecting ring 9 near the front and rear sides, respectively. A take-up roller B752 is fixedly installed at the end of both the straight rod 751 and the support rod 753, and the connecting rope 75 is located on the outer periphery of the adjacent take-up roller B752.

[0037] Specifically, by setting up a straight rod 751, a support rod 753, and a winding roller B752, the connecting rope 75 can be supported, which can prevent the connecting rope 75 from affecting the subsequent water supply effect of the fixed pipe 10 when winding.

[0038] To prevent filter 81 from becoming clogged, in this embodiment, as follows: Figure 4 As shown, the collection component 8 includes a filter screen 81 fixedly installed in the inner cavity of the collection pipe 4 near the middle position. The bottom of the inner cavity of the collection pipe 4 is provided with grooves A82, B83 and C84, which are arranged linearly from left to right. The depths of grooves A82, B83 and C84 are 0.2, 0.4 and 0.6 cm respectively. (Relationship between flow velocity and pressure (Bernoulli's principle): The water flow velocity is faster in the main channel of the pipe, so the pressure is lower. When the water flows through the tank, the space inside the tank is relatively large, and the flow velocity will be significantly slowed down or eddies will be formed. Therefore, the pressure inside the tank is relatively high. The trajectory of the particles: When the stone particles move with the water flow, they will naturally move from the high-speed low-pressure area (main channel) to the low-speed high-pressure area (inside the tank). Once the stone rolls into or jumps out of the tank, the eddies or swirling flow in the groove will make it difficult for it to escape, just like a whirlpool in the water flow will catch a leaf.)

[0039] Specifically, particles of different sizes have different kinetic energy and inertia. Shallower tanks may capture smaller and lighter particles, while deeper and larger tanks can stably accommodate larger and heavier particles. Multiple tanks of different depths greatly increase the system's capture capacity and avoid the problem of a single filter easily becoming clogged.

[0040] To prevent filter 81 from becoming clogged and affecting the suction power of collection tube 4 during use, in this embodiment, as follows: Figure 4 , Figure 8 and Figure 9 As shown, the anti-clogging component 6 includes a movable ring 61 located near one side of the inner cavity of the collection tube 4. A striking rod 62 is fixedly installed on the other side of the movable ring 61 near the top and bottom. A limiting ring A63 is fixedly sleeved on the outer periphery of the collection tube 4 near one end, and a limiting ring B64 is fixedly sleeved on the outer periphery of the collection tube 4 near the other end. A sliding seat 65 is fixedly installed on the top and bottom of the collection tube 4, and a sliding ring 66 is slidably connected on the opposite side of the sliding seat 65.

[0041] Specifically, when the filter 81 becomes clogged, the sliding ring 66, under the action of magnetic force, can make the moving ring 61 slide. The tapping rod 62 fixed on the moving ring 61 can tap the filter 81, which can shake off the stones that are clogging the filter 81, thus preventing it from becoming clogged and affecting the suction force of the collection tube 4 during use, and reducing the efficiency of the operation.

[0042] The moving ring 61 has a limit rod 611 that moves through one side near the top, and one end of the limit rod 611 is fixedly connected to the moving ring 61.

[0043] Specifically, by setting the limit rod 611, the movement of the moving ring 61 can be limited, thereby improving the stability of the movement of the moving ring 61.

[0044] The sliding ring 66 and the moving ring 61 have opposite magnetic properties (the sliding ring 66 can move with the moving ring 61 when it moves, and it can move stably without any discontinuity). The striking rods 62 are all made of rubber.

[0045] Specifically, when the sliding ring 66 moves, the moving ring 61 can be moved, and the filter screen 81 can be tapped by the tapping rod 62 fixed on the moving ring 61 to prevent it from becoming clogged.

[0046] On the opposite side of the limiting ring B64 and the limiting ring A63, near the front and rear sides, a reset telescopic rod 641 is fixedly installed. A reset spring 642 is movably sleeved on the outer periphery of the reset telescopic rod 641, and the two ends of the reset spring 642 are fixedly connected to the sliding ring 66 and the limiting ring B64, respectively.

[0047] Specifically, by setting a reset spring 642 and a reset telescopic rod 641, the sliding ring 66 can be restored to its initial state under the action of elastic potential energy after being released.

[0048] The inner cavity of the sliding seat 65 is provided with a sliding groove 651, and the inner cavity of the sliding groove 651 is slidably connected with a sliding block 652, and the opposite side of the sliding block 652 is fixedly connected to the sliding ring 66.

[0049] Specifically, by setting the sliding block 652 to slide in the inner cavity of the sliding groove 651, the sliding ring 66 can be limited when it moves.

[0050] The inner cavity of the sliding block 652 is movably equipped with ball bearings 6521, and the opposite side of the sliding groove 651 is provided with a rolling groove 6522, and the ball bearings 6521 are slidably connected in the inner cavity of the adjacent rolling groove 6522 respectively.

[0051] Specifically, by setting the ball bearing 6521 and the groove 6522, the resistance of the sliding block 652 in the sliding groove 651 can be reduced, making it easier for medical staff to use.

[0052] In summary, the working principle of this invention is as follows: The sheath is inserted into the ureter, providing a working channel for the tube 5. The tube 5 is then inserted into the human body through the sheath. The camera 30 continuously observes the internal condition of the body. When a stone is detected, the laser head 40 can be activated via the base 1 to pulverize the stone. During the pulverization process, water can be sprayed onto the affected area through the fixing tube 10. This water spraying cleans the camera 30 and improves the clarity of the images captured by the camera 30. When it is necessary to remove the stone, it can be removed via an externally connected collection tube 4. During the suction process... With the help of filter 81, stones can be blocked. By setting grooves of different heights and depths, the capture capacity of the system is greatly increased, avoiding the problem of easy clogging of a single filter 81. When filter 81 is clogged, the sliding ring 66 can slide under the action of magnetic force, and the tapping rod 62 fixed on the moving ring 61 can tap the filter 81, which can shake off the stones clogging the filter 81, thus preventing clogging and affecting the suction of the collection tube 4 during use, and reducing the efficiency of the operation.
