Description

Technical Field

[0001] This utility model relates to the field of pet urethral cutting technology, specifically a pet urethral internal cutter with adjustable cutting depth. Background Technology

[0002] Pets are very friendly companions to humans. Due to their digestive system, animals often have higher blood acid levels, which makes them prone to kidney stones and urethral obstruction. Spontaneous cystitis, urinary tract infections, and stress can all lead to urethral obstruction in pets. If left untreated, urethral obstruction can be fatal.

[0003] Traditional oral medications are slow to take effect, especially for stones, and are often ineffective. Treatment typically involves cutting open the pet's urethra with a scalpel. However, existing scalpels cannot precisely control the angle and distance of ejection after the stone is ejected from the urethra. Because different breeds and sizes of pets have different urethral sizes and varying degrees of disease severity, the degree of urethral obstruction also varies, and current surgical scalpels are not well-suited to address these situations. Utility Model Content

[0007] Preferably, the positioning slots are provided in multiple ways, and the positioning slots are arranged in a ring around the positioning ring, and the snap-fit ​​elastic piece and the positioning slots snap-fit ​​each other.

[0008] Preferably, the adjusting cylinder has an internal thread on its wall, the right end of the traction column is threadedly connected to the adjusting cylinder, and a control handle is fixedly connected to the right end of the adjusting cylinder.

[0009] Preferably, the sidewall of the anti-slip hand guard is an inclined structure, and the anti-slip hand guard is a ring structure.

[0010] Preferably, the groove is provided with a mounting platform, the mounting platform is rotatably connected to the cutting blade, and the blocking post is located at the bottom of the cutting blade.

[0011] Preferably, a blocking elastic sheet is fixedly connected to the side end of the mounting platform. The blocking elastic sheet has a V-shaped structure, and a pressing protrusion is fixedly connected to the upper side of the cutting blade. The pressing protrusion abuts against the side end of the blocking elastic sheet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: after the guide rod is inserted into the pet's urethra, the installation platform is pulled by the traction column, thereby controlling the angle and length of the cutting blade popping out, so as to adapt to pets of different sizes and breeds, and also to different degrees of urethral obstruction. The operation is more flexible, and the cutting blade can be adjusted according to the actual situation, ensuring stronger adaptability during surgery, faster surgery, and reduced harm to the pet.

[0018] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an adjustable cutting depth pet urethral cutter, including a handle 1, a guide rod 2 fixedly connected to the left side of the handle 1, a blade groove provided in the middle of the left side of the guide rod 2, a cutting blade 16 provided in the blade groove, the cutting blade 16 can switch between a rotating state and a stationary state to facilitate insertion into the pet urethra and cutting the pet urethra, a blocking post 17 fixedly connected to the inner wall of the blade groove, a traction post 5 horizontally inserted into the middle of the handle 1, a traction rod 3 for controlling the rotation position and cutting depth of the cutting blade 16 fixedly connected to the left side of the traction post 5, the top end of the traction rod 3 fixedly connected to the mounting platform 15, an adjusting cylinder 4 rotatably connected to the right end of the handle 1, a connecting plate 8 for controlling the position of the traction post 5 fixedly connected to the right end of the adjusting cylinder 4, the top end of the connecting plate 8 fixedly A positioning plate 9 is connected, and a snap-fit ​​elastic piece 10 is fixedly connected to the side end of the positioning plate 9. An anti-detachment hand guard 7 is fixedly connected to the side end of the handle 1, and a positioning ring 11 is fixedly connected to the top of the anti-detachment hand guard 7. A connecting groove 12 is provided on the side end of the positioning ring 11, and a fixing protrusion 13 is fixedly connected to the inner wall of the connecting groove 12. A positioning slot 14 for positioning the rotation angle of the connecting plate 8 is provided on the side end of the fixing protrusion 13. When the guide rod 2 is inserted into the pet's urethra, the cutting blade 16 retracts into the blade groove to avoid damage to the pet's urethra when the guide rod 2 is inserted into the pet's urethra. When the cutting blade 16 reaches the place where it needs to be cut, the adjusting cylinder 4 is rotated. The adjusting cylinder 4 can drive the traction column 5 to move. The traction column drives the mounting platform and the cutting blade to move through the traction rod, thereby popping the cutting blade 16 out of the blade groove.

[0020] The upper end of the connecting plate 8 is horizontally set, and the lower end of the connecting plate 8 is inclined. The two corners of the positioning plate 9 are arc-shaped. The two corners of the positioning plate 9 abut against the inner wall of the connecting groove 12. There are multiple positioning slots 14, which are arranged in a ring around the positioning ring 11. The locking elastic piece 10 and the positioning slot 14 are locked together. By rotating the adjusting cylinder 4, the adjusting cylinder drives the connecting plate 8 to rotate, thereby rotating the positioning plate 9 to different angles. During the rotation of the positioning plate 9, the locking elastic piece 10 is locked into different positioning slots 14, thereby positioning the angle of the connecting plate 8 and preventing the cutting blade 16 from moving during the operation, which would affect the operation.

[0021] The adjusting cylinder 4 has an internal thread on its wall. The right end of the traction column 5 is threadedly connected to the adjusting cylinder 4. The right end of the adjusting cylinder 4 is fixedly connected to the control handle 6. By rotating the control handle 6, the traction column 5 moves horizontally along the adjusting cylinder 4.

[0022] The anti-slip hand guard 7 has an inclined side wall and a ring structure. The anti-slip hand guard 7 can restrict the doctor's hands during operation and reduce the doctor's fatigue during surgery.

[0023] The blade groove is equipped with a mounting platform 15, which is rotatably connected to the cutting blade 16. A blocking post 17 is located at the bottom of the cutting blade 16. A blocking elastic sheet 18 is fixedly connected to the side end of the mounting platform 15. The blocking elastic sheet 18 has a V-shaped structure. A pressing protrusion 19 is fixedly connected to the upper side of the cutting blade 16. The pressing protrusion 19 abuts against the side end of the blocking elastic sheet 18. When the mounting platform 15 is pulled and moved by the traction post 5, the lower end of the cutting blade 16 is blocked by the blocking post 17, thereby causing the cutting blade 16 to rotate and pop out of the blade groove. During this process, the pressing protrusion 19 presses the blocking elastic sheet 18, causing the blocking elastic sheet 18 to deform, thereby restricting the position of the cutting blade 16 and preventing the cutting blade 16 from moving during the cutting of the pet's urethra.

[0024] Although embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the usage of the embodiments of the present invention, and is not intended to limit the present invention in any way. Those skilled in the art will understand that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
