Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an umbilical cord cutter. Background Technology

[0002] An umbilical cord cutter is a medical tool specifically designed for cutting the umbilical cord during childbirth. It is usually made of stainless steel and has a sharp blade and an ergonomic handle for easy operation by doctors or midwives. The umbilical cord cutter is typically used after delivery to separate the umbilical cord from the fetus to ensure the baby can breathe smoothly. Its design ensures that the cutting process is quick and smooth, minimizing damage to the umbilical cord.

[0003] Traditional shears cannot be easily disassembled as needed, and the connection points are difficult to clean thoroughly, thus reducing the risk of infection. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides an umbilical cord cutter with two sets of cutting blades that can be easily disassembled as needed. The connection points are easy to clean during cleaning, thereby reducing the risk of infection.

[0005] The technical solution adopted by this utility model to solve its technical problem is an umbilical cord cutter, including a first cutting blade and a second cutting blade, and the ends of the first cutting blade and the second cutting blade are respectively provided with a first annular handle and a second annular handle. A protrusion is provided on one side of the first shearing blade, and a threaded hole is provided on the inner wall of the protrusion. A first reserved hole and a second reserved hole are respectively provided on the first shearing blade and the second shearing blade at positions corresponding to the threaded hole. A limit pin is provided in the first reserved hole and the second reserved hole. One end of the limit pin is provided with an external thread, and the other end of the limit pin is connected to a square nail head. A limit groove is provided on the top of the protrusion.

[0006] By adopting the above technical solution, the first shearing blade and the second shearing blade are locked together by the external thread on the periphery of the end of the limiting pin and the threaded hole opened in the inner wall of the protrusion. During disassembly, only a rotational force needs to be applied to the square nail head to separate the first shearing blade and the second shearing blade.

[0007] Specifically, a copper sleeve is fitted on the outside of the limiting pin.

[0008] By adopting the above technical solution, the copper sleeve facilitates the passage of the first and second pre-drilled holes, allowing the first and second shearing blades to rotate around the periphery of the limiting pin.

[0009] Specifically, a reserved groove is provided on one side of the bottom end of the second annular handle, and a magnetic block is provided in the reserved groove.

[0010] By adopting the above technical solution, and by using the magnetic block set in the reserved slot, when the first ring handle and the second ring handle are close together, that is, when the first shearing blade and the second shearing blade of this shear are together, there is a certain magnetic attraction between the first shearing blade and the second shearing blade, so as to maintain the stability of the shear before the shear is opened again.

[0011] Specifically, both the first and second ring handles have chamfered edges.

[0012] Specifically, the heads of the first and second shearing blades are provided with rounded corners.

[0013] The beneficial effects of this utility model are: The umbilical cord cutter of this utility model utilizes a limiting pin that passes through a first and a second pre-drilled hole. The external thread on the periphery of the limiting pin engages with a threaded hole on the inner wall of the protrusion to lock the first and second cutting blades together. During disassembly, only a rotational force needs to be applied to the square pin head to separate the first and second cutting blades, facilitating cleaning after separation. The two sets of cutting blades of this cutter can be easily disassembled as needed, and the connection points are easy to clean during cleaning, thereby reducing the risk of infection.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] To allow for easy disassembly and cleaning of the two sets of shear blades as needed, thus reducing the risk of infection, such as... Figure 1-5 As shown, the umbilical cord cutter of this utility model includes a first cutting blade 1 and a second cutting blade 2, and the ends of the first cutting blade 1 and the second cutting blade 2 are respectively provided with a first annular handle 3 and a second annular handle 4. A protrusion 8 is provided on one side of the first shearing blade 1, and a threaded hole 10 is provided on the inner wall of the protrusion 8. A first reserved hole 9 and a second reserved hole 14 are respectively provided on the first shearing blade 1 and the second shearing blade 2 at positions corresponding to the threaded hole 10. A limit pin 12 is provided in the first reserved hole 9 and the second reserved hole 14. An external thread 13 is provided on the periphery of one end of the limit pin 12, and a square nail head 7 is connected to the other end of the limit pin 12. A limit groove 11 is provided on the top of the protrusion 8.

[0019] In use, the first shearing blade 1 and the second shearing blade 2 are locked by the engagement of the external thread 13 on the periphery of the end of the limiting pin 12 with the threaded hole 10 on the inner wall of the protrusion 8. When disassembling, only a rotational force needs to be applied to the square pin head 7 to separate the first shearing blade 1 and the second shearing blade 2.

[0020] For example, such as Figure 4 As shown, the present invention also includes a copper sleeve 15 sleeved on the outer side of the limiting nail 12.

[0021] In use, the copper sleeve 15 facilitates the passage of the first reserved hole 9 and the second reserved hole 14, allowing the first shearing blade 1 and the second shearing blade 2 to rotate around the periphery of the limiting pin 12.

[0022] For example, such as Figure 1 As shown, the present invention also includes a reserved groove 5 on one side of the bottom end of the second annular handle 4, and a magnetic block 6 is provided in the reserved groove 5.

[0023] When in use, the magnetic block 6 set in the reserved slot 5 makes the first ring handle 3 and the second ring handle 4 close together, that is, when the first shearing blade 1 and the second shearing blade 2 of this shear are closed, there is a certain magnetic attraction between the first shearing blade 1 and the second shearing blade 2, so as to maintain the stability of the shear before the shear is opened again.

[0024] For example, such as Figure 1 As shown, the present invention also includes chamfers at the edges of the first annular handle 3 and the second annular handle 4.

[0025] When in use, the chamfering can improve the comfort of the second shearing blade 2 and the second ring handle 4 and prevent hand cuts.

[0026] For example, such as Figure 1 As shown, the present invention also includes rounded corners at the heads of the first shearing blade 1 and the second shearing blade 2.

[0027] By setting rounded corners, the safety of this shear can be improved during use.

[0028] In use, the second shearing blade 2 is placed in the limiting groove 11 on the top of the protrusion 8. When the operator rotates the first shearing blade 1 and the second shearing blade 2, the limiting groove 11 can limit the rotation angle. By setting a magnetic block 6 in the reserved slot 5, when the first annular handle 3 and the second annular handle 4 approach each other, there is a magnetic attraction between the first shearing blade 1 and the second shearing blade 2, maintaining the stability of the shears before they are opened again. The limiting pin 12 passes through the first reserved hole 9 and the second reserved hole 14, and the external thread 13 on the outer periphery of the end engages with the threaded hole 10 opened in the inner wall of the protrusion 8, which facilitates locking the first shearing blade 1 and the second shearing blade 2. When disassembling, only a rotational force needs to be applied to the square pin head 7 to complete the separation of the first shearing blade 1 and the second shearing blade 2, which makes it easy to clean the first shearing blade 1 and the second shearing blade 2 after separation. The two sets of shearing blades of this shear can be easily disassembled as needed, and the connection is easy to clean during cleaning, thereby reducing the risk of infection.
