[0002] Pets are a great source of entertainment and joy for people, leading to an increasing number of families keeping them. However, pets can also get sick, and urinary retention caused by urethral stricture is one of the most common diseases in urology. Since pets' urethras are relatively narrow, urinary retention can prevent them from urinating, potentially causing death. Therefore, many people choose surgical treatment when their pets develop urinary retention. This involves inserting a blade into the pet's urethra to cut it. However, this cutting process produces debris and blood, which must be removed promptly to prevent re-blockage. Utility Model Content

[0003] The purpose of this invention is to provide a pet urethral cutter with a flushing function to solve the problems mentioned in the background art.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a pet urethral cutter with a flushing function, comprising an end cylinder 1 and an operating cylinder 5, characterized in that: a guide rod 2 is fixedly connected to the top of the end cylinder 1, the front end of the guide rod 2 is an inclined surface for easy insertion into the pet urethra, the operating cylinder 5 is threaded into the interior of the end cylinder 1, a cutter 6 is rotatably connected to the middle of the operating cylinder 5, the cutter 6 is hollow inside, a connecting post 8 is fixedly connected to one end of the cutter 6, a sliding sleeve 12 is inserted into the other end of the cutter 6, a cutting blade 7 is rotatably connected to the middle of the connecting post 8, and the guide rod 2... The middle is provided with a blade groove 3 for accommodating the cutting blade 7. A connecting cylinder 9 is fixedly connected to the middle of the blade shank 6. A sealing head 13 is fixedly connected to the middle of the sliding sleeve 12. The top end of the sealing head 13 is inserted into the connecting cylinder 9. A connecting cylinder 19 is inserted into the tail end of the sliding sleeve 12. The connecting cylinder 19 is fixedly connected to the inner wall of the operating cylinder 5. A plastic hose 11 is fixedly connected to the tail end of the connecting cylinder 19. A control block 15 for controlling the position of the sealing head 13 is fixedly connected to the outer wall of the sliding sleeve 12. A pressing plate 17 and a control switch 18 are provided at the upper end of the control block 15.

[0017] The upper end of the operating cylinder 5 is slidably connected to a pressing block 10, and the lower end of the pressing block 10 is slidably connected to a squeezing plate 17. The lower end of the squeezing plate 17 is rotatably connected to a squeezing wheel. A spring is provided between the lower end of the pressing block 10 and the control switch 18. The upper end of the control block 15 is provided with a guide groove 16. The inner wall of the right side of the guide groove 16 is inclined. The control block 15 is lower on the left and higher on the right. When the lower end of the squeezing plate 17 is directly opposite the left side of the control block 15, the pressing block 10 cannot be pressed. This makes it convenient for the doctor to operate the operating cylinder 5 and avoid accidental contact. When the lower end of the squeezing block 10 is directly opposite the guide groove 16, the pressing block 10 is pressed. The pressing block 10 squeezes the side wall of the guide groove 16 through the squeezing plate 17 and the squeezing wheel, thereby pushing the control block 15 and the sliding sleeve 12 to slide. The sliding sleeve 12 drives the sealing head 13 to move, opening the connecting cylinder 9, so that disinfectant can be sprayed from the top of the knife rod 6 to rinse the pet's urethra after cutting.

[0018] The control switch 18 has an L-shaped structure. Both ends of the extrusion plate 17 pass through the control switch 18. The right side of the control switch 18 protrudes from the operating cylinder 5. By pushing the control switch 18, the control switch 18 drives the extrusion plate 17 to move, aligning the lower end of the extrusion plate 17 with different positions of the control block 15.

[0019] The outer wall of the top right side of the knife rod 6 and the outer wall of the left side of the connecting cylinder 19 are both stepped structures. The sliding sleeve 12 is inserted into the outer wall of the knife rod 6 and the connecting cylinder 19. The plugging head 13 is a columnar structure with a smaller diameter on the left and a larger diameter on the right. The left side of the plugging head 13 is inserted into the inner wall of the connecting cylinder 19. The right side of the plugging head 13 is provided with multiple connecting grooves 14. When the control block 15 and the sliding groove 12 move, they drive the plugging head 13 to move. After the left side of the plugging head 13 moves out of the inner wall of the connecting cylinder 19, it connects the knife rod 6 and the plastic hose 11.

[0020] A guide block 4 is fixedly connected inside the blade groove 3. The side end of the guide block 4 is an arc-shaped surface. The connecting column 8 and the blade rod 6 are slidably connected. The top of the cutting blade 7 abuts against the arc-shaped surface of the guide block 4. Rotating the operating cylinder 5 causes the blade rod 6 to move. Due to the restriction of the connecting column 8, the cutting blade 7 can only move horizontally, thus inserting the cutting blade 7 into the blade groove 3. Until the cutting blade 7 moves to the guide block 4, the cutting blade 7 pops out of the blade groove 3 after being guided by the guide block 4, making it convenient for the guide rod 2 to be inserted into the pet's urethra.

[0021] Insert the blade 6 and the cutting blade 7 into the middle of the guide rod 2. During pet surgery, insert the guide rod 2 into the pet's urethra. Once it reaches the designated position, rotate the operating cylinder 5. The blade 6 drives the cutting blade 7 to continue moving. The cutting blade 7 rests against the guide block 4. Guided by the guide block 4, the cutting blade 7 pops out of the blade groove 3 to position itself, facilitating the cutting of the pet's urethra. When it is necessary to flush the urethra, move the position of the squeezing plate 17 by controlling the switch 18. Align the lower end of the squeezing plate with the guide groove 16. Press the pressing block 10. The squeezing plate 17 squeezes the control block 15 and pushes the control block 15 and the sliding sleeve 12 to move, opening the connecting cylinder 9 so that disinfectant can be sprayed from the top of the blade 6 to flush the pet's cut urethra.
