Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a visual removal forceps for female ureteral stent tubes. Background Technology

[0002] After ureteral injury or surgery, a ureteral stent is needed to promote wound healing and prevent urine leakage and infection. A ureteral stent is a thin, flexible tube that runs from the kidney to the bladder. Its main function is to support the ureter, prevent ureteral collapse, and ensure that urine can flow smoothly from the kidney to the bladder, resolving obstruction. The female urethra is short and straight, approximately 2.5–5 cm long, averaging about 3.5 cm, with a diameter of 8 mm. It is easily dilated, reaching 10–13 mm.

[0003] A search of existing technology revealed a device called "A Bladder Tube Removal Forceps" (publication number CN216090681U). This device uses a limiting rod and a connecting wire to control the clamping effect on the tube. However, the pulling effect of the connecting wire is unstable, which affects the clamping effect on the tube and may result in the tube falling off.

[0004] Therefore, a visual catheter removal forceps for female ureteral stents is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a visual tube removal clamp for female ureteral stent tubes in order to solve the above-mentioned problems. It improves the unstable pulling effect of the connecting wire, which affects the clamping effect on the tube body and may cause the clamp to fall off.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a visual removal forceps for female ureteral stents, comprising: an extension tube body, one end of which is fixedly connected to a connecting handle, and an operating handle hinged to the surface of the connecting handle; a clamping mechanism, which is installed inside the extension tube body, both ends of which extend to the outside of the extension tube body, and the end of the clamping mechanism near the connecting handle is connected to the surface of the operating handle; wherein, the clamping mechanism includes a movable clamping assembly fixedly connected to the end of the extension tube body away from the connecting handle, a bottom clamping assembly connected to the surface of the movable clamping assembly, a plastic film connected to the surface of the bottom clamping assembly, and the plastic film fixedly connected to the upper inclined surface of the movable clamping assembly.

[0007] Preferably, the movable clamp assembly includes a fixed arc-shaped plate fixedly connected to the end of the extension tube away from the connecting handle. A sloping arc-shaped frame is fixedly connected to the upper end of the fixed arc-shaped plate, and another fixed arc-shaped frame is fixedly connected to one side of the fixed arc-shaped plate. A lower friction groove is formed at the upper end of the fixed arc-shaped frame. The upper sloping surface of the fixed arc-shaped frame is fixedly connected to the surface of the plastic film. Two hinge seats are fixedly connected to the upper end of the fixed arc-shaped plate. The provided lighting source provides bright illumination, facilitating visual observation and adjustment during operation.

[0008] Preferably, the bottom clamp assembly includes a movable arc-shaped frame disposed on the upper end of the fixed arc-shaped frame. A central clamping plate is fixedly connected to the inner wall of the movable arc-shaped frame. Fixed frames, fixedly connected to the inner wall of the movable arc-shaped frame, are disposed on both sides of the central clamping plate. The two fixed frames are hinged to the surfaces of two hinge seats. One side of the movable arc-shaped frame is fixedly connected to the surface of the plastic film. An upper friction groove is formed at the lower end of the movable arc-shaped frame. The operating handle drives the operating rod to move, causing the hinge rod to move accordingly and simultaneously causing the fixed block to shift at an angle, since the fixed frame is hinged to the hinge seat.

[0009] Preferably, two lighting sources are fixedly connected to the inner wall of the fixed arc-shaped plate, and a sliding guide frame is fixedly connected between the two lighting sources. The side clamps and lower biting teeth work together with the middle clamps to improve the biting effect on the tube and enhance the stability of the tube removal operation.

[0010] Preferably, a fixing block is provided on one side of the central clamping plate and fixedly connected to the inner wall of the movable arc-shaped frame. A hinge rod is hinged to the inner wall of the fixing block, and an operating rod is hinged to the other end of the hinge rod. The operating rod is slidably connected to the inner wall of the sliding guide frame.

[0011] Preferably, the inner wall of the fixed arc-shaped frame is fixedly connected to two side clamps, and the upper end of each side clamp is fixedly connected to multiple lower engagement teeth. The lower friction groove increases the friction of the clamping tube.

[0012] Preferably, the central clamping plate is located between the two side clamping plates, and a plurality of upper engagement teeth are fixedly connected to the lower end of the central clamping plate. When the lower end face of the movable arc frame tends to be horizontal, the upper engagement teeth cooperate with the lower engagement teeth to engage the tube body, ensuring the stability of the tube body clamping.

[0013] The beneficial effects of this utility model are:

[0014] 1. The aforementioned visual ureteral stent removal clamp can stably clamp the tube inside the organ under the action of the clamping mechanism. The device can form a relatively firm clamping effect on the tube by using the side clamp and the lower clamping teeth in conjunction with the middle clamp and the upper clamping teeth. In addition, the upper friction groove increases the frictional force of contact with the tube, which makes the tube more stable when it is removed. When closed, it can maintain the stability of clamping and prevent the clamp from falling off.

[0015] 2. By setting up a clamping mechanism, the friction effect on the organ can be reduced when the device moves inside the organ. The surface of both the movable arc frame and the fixed arc plate is arc-shaped, which reduces the wear and tear on the patient's organ mucosa and protects the health of the patient's internal organs. In addition, the plastic soft membrane further reduces the wear and tear on the patient's mucosa when the device is removed, thus reducing the possibility of damage to the patient's internal organs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-5 As shown, a visual removal forceps for female ureteral stent tubes includes: an extension tube body 1, one end of which is fixedly connected to a connecting handle 2, and an operating handle 21 is hinged to the surface of the connecting handle 2; a clamping mechanism 3, which is installed inside the extension tube body 1, with both ends of the clamping mechanism 3 extending to the outside of the extension tube body 1, and the end of the clamping mechanism 3 near the connecting handle 2 connected to the surface of the operating handle 21; wherein, the clamping mechanism 3 includes a movable clamping assembly 32 fixedly connected to the end of the extension tube body 1 away from the connecting handle 2, a bottom clamping assembly 31 connected to the surface of the movable clamping assembly 32, a plastic soft membrane 33 connected to the surface of the bottom clamping assembly 31, and the plastic soft membrane 33 fixedly connected to the upper inclined surface of the movable clamping assembly 32;

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the movable clamp assembly 32 includes a fixed arc plate 321 fixedly connected to the end of the extension tube 1 away from the connecting handle 2. An inclined arc frame 323 is fixedly connected to the upper end of the fixed arc plate 321. A fixed arc frame 322 is fixedly connected to one side of the fixed arc plate 321. A lower friction groove 329 is opened at the upper end of the fixed arc frame 322. The upper inclined surface of the fixed arc frame 322 is fixedly connected to the surface of the plastic film 33. Two hinge seats 324 are fixedly connected to the upper end of the fixed arc plate 321. Two lighting sources 325 are fixedly connected to the inner wall of the fixed arc plate 321. A sliding guide frame 326 is fixedly connected between the two lighting sources 325. Two side clamps 327 are fixedly connected to the inner wall of the fixed arc frame 322. Multiple lower engagement teeth 328 are fixedly connected to the upper end of the side clamps 327.

[0025] The device, through the cooperation of the operating rod 315 and the plastic membrane 33, can reduce the contact friction with the mucosa when extending into the organ. At the same time, the illumination source 325 of the device can provide bright illumination, which is convenient for visual observation and operation adjustment. The device is designed with an arc-shaped fixed arc plate 321 to facilitate movement inside the organ. The lower friction groove 329 is set to increase the friction of clamping the tube body. Furthermore, the side clamp plate 327 and the lower biting teeth 328 work together with the middle clamp plate 312 to improve the biting effect on the tube body and improve the stability of the tube body removal operation.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom clamp assembly 31 includes a movable arc-shaped frame 311 disposed on the upper end of the fixed arc-shaped frame 322. A middle clamping plate 312 is fixedly connected to the inner wall of the movable arc-shaped frame 311. Fixing frames 316 are fixedly connected to the inner wall of the movable arc-shaped frame 311 on both sides of the middle clamping plate 312. The two fixing frames 316 are hinged to the surfaces of two hinge seats 324. One side of the movable arc-shaped frame 311 is fixedly connected to the surface of the plastic film 33. The lower end of the movable arc-shaped frame 311 is open. The upper friction groove 318 is provided, and a fixing block 313 is fixedly connected to the inner wall of the movable arc frame 311 on one side of the middle clamping plate 312. A hinge rod 314 is hinged to the inner wall of the fixing block 313, and an operating rod 315 is hinged to the other end of the hinge rod 314. The operating rod 315 is slidably connected to the inner wall of the sliding guide frame 326. The middle clamping plate 312 is located between the two side clamping plates 327, and a plurality of upper engagement teeth 317 are fixedly connected to the lower end of the middle clamping plate 312.

[0027] The device moves the operating lever 315 via the operating handle 21, which in turn moves the hinge lever 314 and causes the fixed block 313 to shift at an angle. Since the fixed frame 316 is hinged to the hinge seat 324, the movable arc frame 311 rotates synchronously. When the lower end face of the movable arc frame 311 approaches horizontality, the upper biting teeth 317 and the lower biting teeth 328 engage the tube, ensuring the stability of the tube clamping. The arc shape of the movable arc frame 311 and the fixed arc plate 321 reduces frictional damage to the organ. At the same time, the plastic soft film 33 ensures low wear on the organ when the device is withdrawn.

[0028] In use, the operating handle 21 moves the operating rod 315, which in turn moves the hinge rod 314, causing the fixed block 313 to shift at an angle. The fixed frame 316 is hinged to the hinge seat 324, and the movable arc frame 311 rotates synchronously. The fixed arc plate 321 is arc-shaped to facilitate movement inside the organ. The lower friction groove 329 increases the friction of the clamping tube. The side clamping plate 327 and the lower biting teeth 328 work together with the middle clamping plate 312 to ensure stable clamping operation of the tube. When the lower end face of the movable arc frame 311 tends to be horizontal, the upper biting teeth 317 work together with the lower biting teeth 328 to form a clamping action on the tube. The arc shape of the movable arc frame 311 and the fixed arc plate 321 reduces frictional damage to the organ. The plastic soft film 33 ensures low wear on the organ when the device is withdrawn.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
