Description

Technical Field

[0001] This invention relates to a tumor collection and pulverizing device for transurethral bladder tumor resection, belonging to the field of medical device technology. Background Technology

[0002] Bladder tumors are among the most common urological tumors. Worldwide, bladder cancer ranks twelfth in incidence among cancers, and sixth among men. Transurethral resection of bladder tumors (TURP) is the gold standard for treating non-muscle-invasive bladder cancer due to its minimally invasive nature, fewer complications, and faster postoperative recovery. Laser resection is the most commonly used method. During surgery, if the bladder tumor is small and pedunculated, it can be removed directly from the base using a laser. However, if the tumor is large, even with a small pedicle, direct resection from the base is not recommended to avoid bladder perforation. Instead, resection should begin from the top of the tumor and proceed sequentially.

[0003] Existing tumor collection and pulverizing devices used in transurethral bladder tumor resection involve cutting wires inside the device pulverizing and removing the tumor when it enters the tumor resection site through the urethra. However, because there are no protective measures on the outside of the cutting wires, they are prone to touching other parts of the tumor when they enter the tumor site, causing secondary damage to the body. Furthermore, the pulverized tumor tissue cannot be quickly extracted and collected, increasing the risk of surgery for the patient. Summary of the Invention

[0004] The purpose of this invention is to provide a tumor collection and pulverizing device for transurethral bladder tumor resection. This invention has a simple structure and is easy to use. It protects the cutting wire before and during surgery and quickly collects the pulverized tumor, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tumor collection and fragmentation device for transurethral bladder tumor resection includes a handle. A rotating box is fixedly connected to the top of the handle. A display is fixedly connected to the outside of the rotating box. A control panel is fixedly connected to the outside of the rotating box. A sliding groove is formed on the top of the rotating box. A sliding rod is slidably connected inside the sliding groove. A return spring is fixedly connected to the outside of the sliding rod. A protective cover is fixedly connected to the top of the sliding rod. A micro motor is fixedly installed at the bottom of the rotating box. A rotating shaft is fixedly connected to the output end of the micro motor. A connecting ring is fixedly connected to the outside of the rotating shaft. The outside of the connecting ring is fixedly connected to... The device is equipped with a telescopic spring rod, with a compression cover fixedly connected to the end of the telescopic spring rod away from the connecting ring. An electric telescopic rod is fixedly connected to the top of the rotating shaft, a push tube is fixedly connected to the top of the electric telescopic rod, a conduction ring is fixedly connected to the top of the push tube, a cutting wire is fixedly connected to the top of the conduction ring, a leakage hole is opened at the top of the push tube, a flexible tube is fixedly connected to the outside of the push tube, a suction pump is fixedly connected to the end of the flexible tube away from the push tube, a collection box is fixedly connected to the outside of the suction pump, an observation plate is fixedly connected to the outside of the collection box, and a detection mirror is fixedly connected to the top of the protective cover.

[0007] Furthermore, the chutes are symmetrically distributed on the top of the operating box, and the protective cover is slidably connected to the top of the operating box via a slide rod.

[0008] Furthermore, the end of the return spring away from the slide rod is fixedly connected to the inner wall of the slide groove, and the micro motor is located directly below the operating box.

[0009] Furthermore, the control panel is electrically connected to the micro motor, and the top of the rotating shaft is rotatably connected inside the protective cover.

[0010] Furthermore, the number of telescopic spring rods and the compression cover are the same, and the telescopic spring rods and the compression cover are symmetrically distributed on the outside of the connecting ring.

[0011] Furthermore, the electric telescopic rod is electrically connected to the control panel, and the initial position of the top of the push tube is located inside the protective cover.

[0012] Furthermore, the cutting wires are symmetrically distributed on the top of the conductive coil, and the height of the cutting wires is greater than the distance from the conductive coil to the top of the push tube.

[0013] Furthermore, the hose runs through the interior of the operating box, the extraction pump is fixedly connected to the outside of the operating box, and the extraction pump is electrically connected to the control panel.

[0014] Furthermore, the detection mirrors are symmetrically distributed on the top of the protective cover, and the detection mirrors are electrically connected to the display.

[0015] The beneficial effects of this invention are:

[0016] This invention employs a rotating box. A handle at the bottom of the rotating box drives a protective shield at the top of the box through the urethra to the tumor site. Because the cutting wire is located inside the protective shield, it does not damage the inner wall of the urethra during operation. When the protective shield is positioned at the tumor location, a detection mirror and monitor are used to find the appropriate position, allowing the protective shield to surround the tumor. The control panel then activates the electric telescopic rod at the top of the rotating shaft, causing the push tube at its top to rise. As the push tube moves upward, the cutting wire at the top of the conduction coil is exposed inside the protective shield. The control panel then activates a micro motor at the bottom of the rotating box, causing the rotating shaft to rotate. This rotation of the shaft drives the electric telescopic rod and the push tube to rotate. The rotating shaft drives the connecting ring to rotate, causing the telescopic spring rod on the outside of the connecting ring to extend under centrifugal force. This telescopic spring rod then moves the compression shield to compress the protective shield, causing the protective shield to expand outward under the action of its bottom sliding rod. This prevents the cutting wire from damaging the bladder wall during tumor fragmentation. After the cutting wire has fragmented the tumor, the extraction pump on the outside of the operating box is activated via the control panel, creating suction on the inner wall of the tubing. Since one end of the tubing is fixedly connected to the inside of the push tube, the fragmented tumor enters the push tube through the leak at the top of the push tube. Then, through the combined action of the tubing and the extraction pump, it enters the collection box, achieving rapid collection. Attached Figure Description

[0028] Specifically, such as Figure 1As shown, the slide grooves 5 are symmetrically distributed on the top of the operating box 2. The protective cover 8 is slidably connected to the top of the operating box 2 via the slide rod 6. The end of the return spring 7 away from the slide rod 6 is fixedly connected to the inner wall of the slide groove 5. The micro motor 9 is located directly below the operating box 2. The control panel 4 is electrically connected to the micro motor 9. The top of the rotating shaft 10 is rotatably connected to the inside of the protective cover 8.

[0029] Specifically, such as Figure 1-6 As shown, the number of telescopic spring rods 12 and the number of extrusion covers 13 are the same, and the telescopic spring rods 12 and the extrusion covers 13 are symmetrically distributed on the outside of the connecting ring 11. The electric telescopic rod 14 is electrically connected to the control panel 4. The initial position of the top of the push tube 15 is located inside the protective cover 8. The cutting wires 17 are symmetrically distributed on the top of the conduction ring 16, and the height of the cutting wires 17 is greater than the distance from the conduction ring 16 to the top of the push tube 15. The hose 19 runs through the inside of the operating box 2. The extraction pump 20 is fixedly connected to the outside of the operating box 2, and the extraction pump 20 is electrically connected to the control panel 4. The detection mirror 23 is symmetrically distributed on the top of the protective cover 8, and the detection mirror 23 is electrically connected to the display 3.

[0030] Please refer to Example 2 Figure 1 , Figure 2 and Figure 6 The difference between this embodiment and embodiment 1 is that: the top of the push tube 15 is provided with a leakage hole 18, a hose 19 is fixedly connected to the outside of the push tube 15, a pump 20 is fixedly connected to the end of the hose 19 away from the push tube 15, a collection box 21 is fixedly connected to the outside of the pump 20, an observation plate 22 is fixedly connected to the outside of the collection box 21, and a detection mirror 23 is fixedly connected to the top of the protective cover 8.

[0031] Working principle of this invention: A rotating box 2 is installed. The handle 1 at the bottom of the rotating box 2 drives the protective cover 8 at the top of the rotating box 2 through the urethra to the tumor site. Since the cutting wire 17 is located inside the protective cover 8, it will not damage the inner wall of the urethra during operation. When the protective cover 8 is at the tumor location, the detection mirror 23 and the display 3 work together to find the appropriate position, allowing the protective cover 8 to surround the tumor. Then, the control panel 4 activates the electric telescopic rod 14 at the top of the rotating shaft 10, causing the electric telescopic rod 14 to drive the push tube 15 at its top to rise. When the push tube 15 moves upward, the cutting wire 17 at the top of the conduction coil 16 is exposed inside the protective cover 8. The control panel 4 then activates the micro motor 9 at the bottom of the rotating box 2, causing the micro motor 9 to drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the electric telescopic rod 14 and the push tube 15 to rotate. The cutting wire 17 at the top of the conduction coil 16 pulverizes the tumor. The rotation of the rotating shaft 10 drives the connecting ring 11 to rotate, causing the telescopic spring rod 12 on the outside of the connecting ring 11 to extend under the action of centrifugal force. At this time, the telescopic spring rod 12 will drive the compression cover 13 to move and squeeze the protective cover 8, causing the protective cover 8 to expand outward under the action of the bottom slide rod 6, preventing the cutting wire 17 from damaging the inner wall of the bladder when pulverizing the tumor. After the cutting wire 17 pulverizes the tumor, the extraction pump 20 on the outside of the operating box 2 is started through the control panel 4, which causes the inner wall of the hose 19 to generate suction. Since one end of the hose 19 is fixedly connected to the inside of the push tube 15, the pulverized tumor enters the inside of the push tube 15 through the leakage hole 18 at the top of the push tube 15. Then, through the cooperation of the hose 19 and the extraction pump 20, it enters the inside of the collection box 21, achieving the effect of rapid collection.
