[0002] In the experiment of constructing an animal model of arterial stenosis, it is often necessary to squeeze the animal blood vessels to simulate the state of blood vessel stenosis, so as to study the pathogenesis of related diseases.

[0003] Currently, experimenters usually use the method of tying with a strap or clamping with a fixture to squeeze the blood vessels. However, both of the above two methods have certain limitations in actual use: when using the method of tying the blood vessels with a strap, since the tightness of the tying depends on the experimenter's experience judgment, it is impossible to accurately adjust the blood vessels according to the stenosis degree required by the experiment, which is not conducive to use; when using the method of clamping with a fixture, due to the different thicknesses of animal blood vessels and the different stenosis degrees required by the experiment, it is impossible to adjust the stenosis degree of the blood vessels according to the requirements of the experiment, and at the same time, it is impossible to adapt to blood vessels of different thicknesses, so it is inconvenient to use. Utility Model Content

[0004] In order to achieve the purpose of flexible adjustment according to the different thicknesses of animal blood vessels and the stenosis degree required by the experiment on the premise of effectively squeezing the animal blood vessels, the present application provides an adjustable strap-type animal blood vessel stenosis modeling device.

[0005] An adjustable strap-type animal blood vessel stenosis modeling device provided by the present application adopts the following technical solutions:

[0006] An adjustable strap-type animal blood vessel stenosis modeling device includes a strap, one end of the strap is provided with a socket hole, the other end of the strap is slidably inserted into the socket hole, a clamping structure for clamping and positioning the strap is arranged on the strap, the strap can enclose to form a squeezing space for squeezing and limiting the animal blood vessels, and scale lines are arranged on the strap.

[0007] By adopting the above technical solutions, when in use, one end of the strap is bypassed around the animal blood vessel and then inserted into the socket hole, and then the strap is clamped and positioned by the clamping structure, so as to tie the strap on the animal blood vessel. At this time, a squeezing space is formed in the middle of the strap. Then, the size of the squeezing space can be adjusted through the clamping structure, so as to achieve the purpose of adjusting the stenosis degree of the animal blood vessels according to the experimental needs. At the same time, the experimenter can accurately control the size of the squeezing space according to the position of the scale lines, and the overall use is simple and convenient.

[0008] Preferably, the clamping structure includes a clamping block slidably disposed on the strap. One end of the clamping block is located within the insertion hole, and the other end of the clamping block is located outside the insertion hole. A plurality of clamping grooves for clamping and embedding the clamping block are formed in the strap, and the plurality of clamping grooves are uniformly spaced along the length direction of the strap. An elastic member is provided on the strap for driving the clamping block to embed into the clamping groove.

[0009] By adopting the above technical solution, during use, after one end of the strap is inserted into the insertion hole, under the action of the elastic member, one end of the clamping block is embedded into the clamping groove, thereby realizing the clamping and positioning of the strap. When it is necessary to adjust the tightness of the strap bundling, the experimenter can achieve this by embedding the clamping block into the clamping grooves at different positions. The use process is simple and convenient.

[0010] Preferably, a tooth is formed between two adjacent clamping grooves. A first guiding inclined surface is formed on one side of the tooth facing the insertion end of the strap. A second guiding inclined surface is formed at one end of the clamping block located within the insertion hole. The first guiding inclined surface and the second guiding inclined surface are arranged in parallel.

[0011] By adopting the above technical solution, during use, through the combined use of the first guiding inclined surface and the second guiding inclined surface, it is more convenient to adjust the tightness of the strap bundling.

[0012] Preferably, the elastic member is a spring. One end of the spring is fixedly connected to the clamping block, and the other end is fixedly connected to the strap.

[0013] By adopting the above technical solution, during use, the spring abuts against the clamping block to ensure that the clamping block is embedded into the clamping groove. When it is necessary to drive the clamping block out of the clamping groove, the clamping block can be pressed to compress the spring, and then the strap is moved to a suitable position and the clamping block is released. Under the elastic force of the spring, the clamping block slides and embeds into the clamping groove, making the use more convenient.

[0014] Preferably, a pressing block is fixed to one end of the clamping block located outside the insertion hole.

[0015] By adopting the above technical solution, during use, by providing a pressing block on the clamping block, it is convenient for the experimenter to press the clamping block.

[0016] Preferably, the outer wall of the pressing block is provided with anti-slip lines.

[0017] By adopting the above technical solution, during use, by providing anti-slip lines on the pressing block, the friction force on the outer wall of the pressing block is increased, making it more convenient for the experimenter to use.

[0018] Preferably, the clamping structure includes an insertion rod rotatably mounted on the binding strap, and the binding strap is provided with a plurality of insertion holes for embedding the insertion rod, and the plurality of insertion holes are evenly spaced along the length direction of the binding strap.

[0019] By adopting the above technical solution, when one end of the strap passes through the plug-in hole during use, the experimenter can rotate the insertion rod so that one end of the insertion rod is inserted into the plug-in hole, thereby realizing the clamping of the strap. At the same time, according to the needs of the experiment, the size of the extrusion space can be adjusted by inserting the insertion rod into the plug-in hole at different positions.

[0020] Preferably, the binding strap is provided with an embedding groove for embedding the insertion rod, and one end of the insertion rod can be embedded in the embedding groove after passing through the insertion hole.

[0021] By adopting the above technical solution, the end of the insertion rod is limited by the embedded groove during use, thereby increasing the stability of the insertion rod after being inserted into the socket, thereby preventing the insertion rod from detaching from the socket without external force, thereby ensuring the tightness of the bandage binding the animal's blood vessels.

[0022] Preferably, the strap is provided with a sliding limiting sleeve, and the limiting sleeve is provided with a limiting hole for limiting the strap.

[0023] By adopting the above technical solution, when the insertion rod is inserted into the insertion hole during use, the end of the strap can be limited by the limiting sleeve, thereby preventing the end of the strap from swinging and affecting the binding tightness of the strap.

[0024] Preferably, a guide wire for guiding one end of the binding strap to be inserted into the insertion hole is fixed on the end of the binding strap away from the insertion hole.

[0025] By adopting the above technical solution, when in use, the guide wire is first passed into the plug hole, and then the end of the binding belt is inserted into the plug hole by pulling the guide wire, so as to facilitate the binding of the binding belt.

[0037] The following further elaborates on the present application in conjunction with the attached Figure 1 - attached Figure 6 drawings for a more detailed description.

[0038] Embodiment 1 of the present application discloses an adjustable strap-type animal blood vessel stenosis modeling device.

[0039] Embodiment 1:

[0040] Refer to Figure 1 and Figure 2, An adjustable strap-type animal blood vessel stenosis modeling device, including a horizontally placed strap 1. In this embodiment, the strap 1 is preferably set as a strip structure made of flexible silica gel. The strap 1 includes a belt body 11 and a clamping joint 12. The clamping joint 12 is integrally formed at the left end of the belt body 11. An insertion hole 2 is opened on the clamping joint 12. One end of the belt body 11 away from the clamping joint 12 can be bent and inserted into the insertion hole 2. At this time, an extrusion space 4 is formed between the two ends of the strap 1. The extrusion space 4 is used for the animal blood vessel to pass through and at the same time squeezes and limits the blood vessel.

[0041] Refer to Figure 3 and Figure 4 , A clamping structure 3 is provided on the clamping joint 12. The clamping structure 3 is used to clamp and limit the belt body 11, so as to prevent the belt body 11 from sliding out of the insertion hole 2. The clamping structure 3 includes a clamping block 31. The clamping block 31 slides in the clamping joint 12 along the length direction of the strap 1. One end of the clamping joint 12 is located inside the insertion hole 2, and the other end of the clamping joint 12 is located outside the insertion hole 2. A clamping groove 32 for embedding the clamping block 31 is opened on the top surface of the belt body 11. An elastic member 6 is provided on the clamping joint 12; during use, one end of the belt body 11 is wound around the animal blood vessel and then inserted into the insertion hole 2. When the clamping block 31 is aligned with the clamping groove 32, the clamping block 31 slides and embeds into the clamping groove 32 under the action of the elastic member 6, so as to realize clamping the belt body 11 and the clamping joint 12 together, and further realize the extrusion of the animal blood vessel.

[0042] Refer to Figure 2 and Figure 3 , A plurality of clamping grooves 32 are provided, and the plurality of clamping grooves 32 are arranged at equal intervals along the length direction of the belt body 11. A clamping tooth 7 is formed between two adjacent clamping grooves 32. A first guiding inclined surface 71 is integrally formed at one end of the clamping tooth 7 facing the clamping joint 12. A second guiding inclined surface 72 is integrally formed on the clamping block 31. The first guiding inclined surface 71 and the second guiding inclined surface 72 are parallel to each other; during use, a plurality of clamping grooves 32 are provided. The experimenter adjusts the size of the extrusion space 4 according to the experimental needs by embedding the clamping block 31 into the clamping grooves 32 at different positions. After one end of the belt body 11 is inserted into the insertion hole 2, through the cooperation of the first guiding inclined surface 71 and the second guiding inclined surface 72, it is convenient for the experimenter to pull the belt body 11, so as to reduce the size of the extrusion space 4 and make it more convenient to use.

[0043] Refer to Figure 3 and Figure 5, the elastic member 6 is set as a spring 61. The spring 61 is located inside the clamping joint 12, and one end of the spring 61 is adhesively fixed to the clamping joint 12, and the other end abuts against the clamping block 31. At the same time, a pressing block 8 is integrally formed on the clamping block 31. The pressing block 8 is located outside the insertion hole 2, and the pressing block 8 slides on the clamping joint 12. Anti-slip lines are integrally formed on the pressing block 8. During use, the experimenter can press down the pressing block 8, drive the clamping block 31 to slide through the sliding of the pressing block 8, so that one end of the clamping block 31 disengages from the clamping groove 32. After that, the size of the extrusion space 4 can be enlarged. After the adjustment is completed, just release the pressing block 8. Under the action of the spring 61, the pressing block 8 slides back to its original position and drives the clamping block 31 to be inserted into the clamping groove 32.

[0044] Refer to Figure 1 , a guiding wire 20 is integrally formed at one end of the belt body 11 away from the plug joint. A scale line 5 is formed by cutting on the bottom surface of the belt body 11. During use, the guiding wire 20 can facilitate the experimenter to insert the belt body 11 into the insertion hole 2. The scale line 5 is convenient for the experimenter to observe the tightness degree after the binding band 1 is tied. At the same time, it can also be assisted by the scale line 5, which is convenient for the experimenter to tie the animal blood vessel to the specified stenosis degree through the binding band 1, and cooperate with the clamping structure 3 to realize the precise adjustment of the extrusion space 4.

[0045] The implementation principle of the embodiment of the present application is as follows: During use, first take the binding band 1 to the position of the animal blood vessel, then pull the guiding wire 20 to drive the belt body 11 to bend, so that one end of the guiding wire 20 passes around the blood vessel and then penetrates into the insertion hole 2. Continue to pull the guiding wire 20 until the end of the belt body 11 away from the clamping joint 12 is inserted into the insertion hole 2. After that, the experimenter can adjust the position of the clamping block 31 according to the experimental needs and the thickness of the animal blood vessel. When the clamping groove 32 is inserted into the corresponding clamping groove 32 at the specified position, the belt body 11 and the clamping joint 12 can be clamped into an annular structure, so as to simulate the animal blood vessel stenosis modeling by squeezing the animal blood vessel through the belt body 11. When it is necessary to adjust the size of the extrusion space 4, the experimenter can press down the pressing part to make the clamping block 31 disengage from the clamping groove 32, and then pull the belt body 11 to realize the adjustment of the size of the extrusion space 4. The overall use is simple and convenient, and it can be flexibly adjusted according to the thickness of the animal blood vessel and the stenosis degree required by the experiment.

After the clamping of the belt body 11 and the clamping joint 12 is completed, the end of the belt body 11 away from the clamping joint 12 is inserted into the limiting hole 101, so as to prevent the belt body 11 from swinging and causing the insertion rod 33 to disengage from the embedding groove 9, thereby increasing the clamping stability of the clamping structure 3.

[0049] The implementation principle of the embodiment of the present application is as follows: when in use, first take the bandage 1 to the position where the animal's blood vessel is located, then pull the guide wire 20 to drive the band body 11 to bend, so that one end of the guide wire 20 bypasses the blood vessel and then penetrates into the plug hole 2, and continue to pull the guide wire 20 until the band body 11 is away from the end of the card connector 12 and is inserted into the plug hole 2. After that, the experimenter can adjust the position of the insertion rod 33 according to the experimental needs and the thickness of the animal's blood vessel. When the end of the insertion rod 33 passes through the plug hole 34 at the specified position and is embedded in the embedding groove 9, the band body 11 and the card connector 12 can be connected into a ring structure. , thereby simulating animal blood vessel stenosis by squeezing the animal blood vessel through the belt body 11; when the size of the squeezing space 4 needs to be adjusted, the experimenter can rotate the insertion rod 33 and the belt body 11 so that the insertion rod 33 is disengaged from the insertion hole 34, and then pull the belt body 11 to adjust the size of the squeezing space 4. After the adjustment is completed, the insertion rod 33 is inserted into the insertion hole 34, and one end of the belt body 11 is inserted into the limiting hole 101, so as to ensure the clamping stability of the clamping structure 3. The overall use is simple and convenient, and it can be flexibly adjusted according to the different thicknesses of the animal blood vessels and the degree of stenosis required by the experiment.
