Technical Field

[0001] This utility model relates to the field of pet treatment technology, specifically a pet urethral cutter with a replaceable blade. Background Technology

[0002] Pets have relatively narrow urethras, making them very susceptible to urinary retention. Traditional oral treatments are slow to take effect and are less effective for some acute cases. Therefore, a common treatment method is incision, where a scalpel is inserted into the pet's urethra during surgery to cut it. To avoid cross-infection, the blade needs to be replaced. However, existing internal cutting blades have relatively long shanks, and since the blade is inserted into the shank, it is easy for the blade to rotate during installation and removal, causing it to become stuck inside the shank and preventing separation.

[0015] Please see Figure 1-2This utility model provides a technical solution: a pet urethral cutter with replaceable blade head, including an operating head 1, a blade rod 2 fixedly connected to the top of the operating head 1, a placement groove 3 in the middle of the blade rod 2, a magnet 8 placed in the placement groove 3, a blade 6 placed in the placement groove 3, a guide slope 7 at the top of the blade 6, a pressing rod 9 inserted into the middle of the blade rod 2, the top of the pressing rod 9 abutting against the guide slope 7, the pressing rod 9 being used to control the blade 6 to rotate and extend out of the blade rod 2, and a locking groove 4 on the side end of the blade rod 2. A limiting plate 5 is placed in the middle of the operating head 1. A fixing ring 10 is threadedly connected to the middle of the knife bar 2. The fixing ring 10 is used for positioning and pressing the limiting plate 5. The operating head 1 has a cavity inside. The top of the knife bar 2 is located in the cavity. A spring is provided between the top of the knife bar 2 and the cavity. A guide block 14 is fixedly connected to the top of the knife bar 2. The side end of the guide block 14 is an inclined surface. A pressing plate 13 is inserted into the side end of the operating head 1. The top of the pressing plate 13 abuts against the inclined surface of the guide block 14. A connecting rod 15 is provided on the side end of the pressing plate 13.

[0016] The top of the limiting plate 5 is fixedly connected to the mounting platform 20. The mounting platform 20 and the limiting plate 5 form a stepped structure. The top of the snap-fit ​​groove 4 is a stepped structure. The mounting platform 20 is snapped into the snap-fit ​​groove 4. When the limiting plate 5 and the snap-fit ​​groove 4 are installed, the top of the snap-fit ​​groove 4 can limit and fix the mounting platform 20.

[0017] The limiting plate 5 has a telescopic opening 19 in the middle, and the blade 6 is located at the telescopic opening 19. The lower end of the limiting plate 5 is fixedly connected to two mounting plates 16, and the blade 6 is located between the two mounting plates 16. The mounting plate 16 has a mounting hole 17 in the middle, and a mounting post 18 is inserted between the two mounting plates 16 and the blade 6. The inner wall of the placement groove 3 has a slot, and the mounting post 18 is inserted into the slot. When the blade 6 needs to be replaced, the blade 6 is placed between the two mounting plates 16 and positioned by inserting the mounting post 18. Connecting the mounting post 18 to the slot can restrict the mounting post 18.

[0018] The side end of the limiting plate 5 is fixedly connected to a positioning protrusion 12. The cross-section of the fixing ring 10 is L-shaped. The inner wall of the fixing ring 10 is provided with a positioning groove 11 with an annular structure. The positioning protrusion 12 and the positioning groove 11 are engaged. When the limiting plate 5 is installed and fixed, the fixing ring 10 is rotated and the fixing ring 10 moves to the positioning protrusion 12. At this time, the fixing ring 10 squeezes the positioning protrusion 12, causing the fixing ring 10 to undergo slight deformation, so that the positioning protrusion 12 is engaged in the positioning groove 11.

[0019] The top of the extrusion plate 13 abuts against the inclined surface of the guide block 14. The side end of the extrusion plate 13 is provided with multiple insertion interfaces. The insertion rod 15 and the operating head 1 are slidably connected. The top of the insertion rod 15 is inserted into the insertion interface. When it is necessary to cut the pet's urethra, press the extrusion plate 13. The extrusion plate 13 extrudes the guide block 14, thereby pushing the extrusion rod 9 to move. The extrusion rod 9 pushes the blade 6 to rotate, thereby popping the blade 6 out of the telescopic port 19. At this time, the insertion rod 15 is inserted into the insertion interface to fix the blade 6.

[0020] When the blade needs to be replaced, place the blade 6 between the two mounting plates 16 and insert the mounting post 18 into the mounting hole 17 to position the blade 6.
