Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular is a collagen thread cutting device based on acupuncture thread embedding. Background Art

[0002] Acupuncture thread embedding collagen thread is a beauty therapy that combines traditional Chinese medicine acupuncture and modern medical technology. Specifically, it embeds specially made collagen threads into specific acupuncture points on the skin to achieve the effects of promoting collagen production, improving skin sagging, enhancing facial contours and reducing wrinkles.

[0003] When using existing acupuncture thread embedding needles, the collagen thread is generally cut into a predetermined length in advance according to the treatment needs and the acupuncture point location, and then inserted into the needle hole in sequence. There are also a few thread embedding needles on the market that are equipped with a cutter inside the needle tube for ease of use. However, when the cutter cuts the thread embedding needle, since the thread embedding needle has no effective support platform inside the needle tube, it is easy to cause the collagen thread to slip or deflect during the thread cutting operation, thereby affecting the cutting efficiency and accuracy, and in severe cases causing unnecessary harm to the patient.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides a collagen thread cutting device based on acupoint thread embedding, comprising a handle 1 and further comprising:

[0036] The needle tube 2 is fixedly connected to one end of the handle 1;

[0037] The rotating assembly 3 is symmetrically arranged inside the needle tube 2, and the internal movably connected to the clamping assembly 4;

[0038] A movable assembly 5 is movably connected to the handle 1 and the interior of the needle tube 2, and one end of the movable assembly 5 is fixedly connected to a connecting rod assembly 6;

[0039] The cutter 7 is movably connected to the inside of the needle tube 2, and a push component 8 is symmetrically provided on both sides;

[0040] The rotating assembly 3 includes a rotating drum 301 , and an outer wall of the rotating drum 301 is provided with an inclined groove 302 with an arc of 90 degrees and a vertical groove 303 with an arc of zero degrees.

[0041] The above-mentioned solution is adopted: the protrusion 505 is movably engaged with the inside of the inclined groove 302, so that when the first limit block 504 moves, it drives the two rotating drums 301 to rotate ninety degrees, and the first round rod 404 drives the clamping block 403 to move toward the direction of the collagen line 9 along the trajectory of the guide groove 402, so that the clamping block 403 drives the arc gasket 405 to clamp the collagen line 9. The arc gasket 405 is made of silicone material, which makes it convenient to position the collagen line 9 while reducing damage to the surface of the collagen line 9. The two sets of arc gaskets 405 are used to clamp the two ends of the cut part of the collagen line 9 respectively.

[0042] like Figures 1 to 8 As shown, a collagen line 9 is provided inside the needle tube 2, and a line hole 10 is provided on the surface of the needle tube 2. The opposite ends of the two rotating cylinders 301 are both inclined, and the opposite ends of the inclined groove 302 and the vertical groove 303 are connected. The clamping assembly 4 includes a turntable 401, and a guide groove 402 is provided on the surface of the turntable 401. The curvature of the guide groove 402 is ninety degrees. The inside of the guide groove 402 is movably connected with a first round rod 404, and the outer wall of the first round rod 404 is fixedly connected with a clamping block 403, and the side of the clamping block 403 away from the first round rod 404 is fixedly connected with an arc gasket 405, and the arc gasket 405 is made of silicone material. The inner wall of the handle 1 is provided with a straight slot 407 that matches the first round rod 404. The straight slot 407 is used to circumferentially limit the first round rod 404 when the rotating cylinder 301 rotates.

[0043] The above solution is adopted: the opposite ends of the two rotating cylinders 301 are both inclined. Its function is that when the collagen thread 9 is inserted into the needle tube 2, it may contact the side wall of the rotating component 3. The inclined surface design allows the collagen thread 9 to slide along the inclined surface. Compared with the flat design, this method can significantly reduce the insertion force required for the collagen thread 9, thereby making the operation smoother.

[0044] The arc-shaped gasket 405 is made of silicone material. Since silicone material has excellent elasticity, toughness and biocompatibility, the arc-shaped gasket 405 can clamp the collagen thread 9 while reducing damage to the collagen thread 9.

[0045] like Figures 5 to 8As shown, the inner wall of the rotating cylinder 301 is provided with a sliding groove 304 for circumferentially limiting the rotating disk 401, and the side of the rotating disk 401 away from the clamping block 403 is fixedly connected to the first spring 406 fixedly connected to the rotating cylinder 301, the first spring 406 is used to squeeze the rotating disk 401 and keep the two rotating disks 401 moving toward each other, the moving component 5 includes a pushing block 501, the pushing block 501 is located outside the handle 1, and the handle 1 is internally movably connected to a moving block 502 fixedly connected to the pushing block 501, one side of the moving block 502 is fixedly connected to a second spring 503 fixedly connected to the handle 1, and the end of the moving block 502 away from the pushing block 501 is fixedly connected to the first limiting block 504 and the second limiting block 506 respectively.

[0046] The above solution is adopted: through the design of the second spring 503, its function is that when the device completes the tangent, at this time, the operator releases the push block 501, so that the moving block 502 is reset under the action of the elastic force of the second spring 503, and then drives the entire structure inside the needle tube 2 to reset, so as to facilitate the operator's next use.

[0047] like Figure 6 As shown, one side of the first limit block 504 is fixedly connected to two protrusions 505, and the two protrusions 505 are movably engaged in the inside of the two inclined grooves 302. When the first limit block 504 moves toward the direction of the rotating component 3, it drives the protrusion 505 to slide along the trajectory of the inclined groove 302 and causes the rotating drum 301 to rotate. The inside of the second limit block 506 is movably connected to the second round rod 507, and the outside of the second round rod 507 away from the end of the second limit block 506 is movably sleeved with a third spring 508. The two ends of the third spring 508 are respectively fixedly connected to the handle 1 and the second round rod 507, and the end of the connecting rod assembly 6 away from the second round rod 507 is fixedly connected to the cutter 7.

[0048] The above solution is adopted: through the design of the third spring 508, its function is that the third spring 508 is used to squeeze the second round rod 507 and keep the second round rod 507 moving away from the connecting rod assembly 6. When the moving block 502 drives the second limit block 506 to reset under the action of the elastic force of the second spring 503, the second round rod 507 moves toward the inside of the second limit block 506 under the action of the elastic force of the third spring 508, and then drives the cutter 7 to move upward through the connecting rod assembly 6, thereby ensuring the normal operation of the device.

[0049] like Figures 3 and 4 、 Figures 6 to 8As shown, both ends of the bottom of the cutter 7 are inclined, and the pushing component 8 includes a round block 801. The top of the outer wall of the round block 801 is fixedly connected to the inclined block 802. The opposite sides of the two inclined blocks 802 are inclined, and the two ends of the bottom of the cutter 7 are respectively abutted against the inclined surfaces of the two inclined blocks 802. The side of the inclined block 802 away from the cutter 7 is fixedly connected to the spring 803. The spring 803 is fixedly connected to the handle 1. When the cutter 7 moves downward, it squeezes the two inclined blocks 802 to move in opposite directions. After the inclined block 802 moves, it drives the round block 801 to abut against the clamping block 403 and pushes the clamping block 403 to move in the direction of the first spring 406.

[0050] The above solution is adopted: through the design of the connecting rod assembly 6, the force of the second round rod 507 moving toward the connecting rod assembly 6 is converted into a force for the cutter 7 to move downward. The cutter 7 abuts against the inclined surfaces of the two inclined blocks 802, thereby facilitating the squeezing of the two inclined blocks 802 to move in opposite directions. The inclined blocks 802 then drive the round block 801 to abut against the side walls of the clamping block 403. The round block 801 squeezes the clamping block 403 to move in the direction of the first spring 406, thereby causing the two sets of arc-shaped gaskets 405 to respectively drive the clamped ends of the collagen thread 9 to move in opposite directions, thereby tightening the middle parts of the clamped ends, thereby improving the accuracy of the cutter 7 in cutting the collagen thread 9.

[0051] The design of the spring piece 803 has the following function: when the cutter 7 moves upward and releases the squeeze on the two inclined blocks 802, the two inclined blocks 802 move toward each other under the elastic force of the spring piece 803, and drive the round block 801 to reset, so that the round block 801 releases the squeeze on the clamping block 403, and the clamping block 403 is reset under the elastic force of the first spring 406, which makes it convenient for the operator to use it next time.

[0052] The working principle and use process of the present invention are as follows: when the length of the collagen thread 9 needs to be cut, at this time, the operator pushes the push block 501 in the direction of the needle tube 2, so that the push block 501 drives the moving block 502 to move in the same direction. When the moving block 502 moves, it drives the first limiting block 504 and the second limiting block 506 to move together, so that the first limiting block 504 drives the two protrusions 505 to slide along the trajectory of the inclined groove 302, thereby driving the rotating drum 301 to rotate ninety degrees. When the rotating drum 301 rotates, the circumferential limit of the turntable 401 is set by the slide groove 304, thereby driving the turntable 401 to rotate together, thereby making the first limiting block 504 and the second limiting block 506 move together. The round rod 404 slides along the trajectory of the guide groove 402. As the first round rod 404 slides, the straight groove 407 limits the circumferential position of the first round rod 404, so that when the first round rod 404 slides, it can only drive the clamping block 403 and the arc-shaped gasket 405 thereon to move toward the direction of the collagen line 9. When the protrusion 505 slides to the inside of the vertical groove 303, the two sets of arc-shaped gaskets 405 abut against the collagen line 9 and clamp the two ends of the collagen line 9, thereby fixing the position of the collagen line 9, and further providing a certain support for the subsequent cutting operation, thereby preventing the collagen line 9 from shaking when being cut, affecting the cutting accuracy;

[0053] When the second limiting block 506 moves, the second round rod 507 slides inside it. When the protrusion 505 slides into the interior of the vertical groove 303, the inner wall of the second limiting block 506 abuts against one end of the second round rod 507. Then, the moving block 502 continues to move, so that the protrusion 505 slides along the trajectory of the vertical groove 303. At the same time, the second limiting block 506 pushes the second round rod 507 to move in the direction of the cutter 7. When the second round rod 507 moves, the direction of the force is converted by the connecting rod assembly 6, so that the second round rod 507 moves and brings The movable cutter 7 moves downward, thereby causing the cutter 7 to squeeze the two oblique blocks 802 to move in opposite directions. The oblique blocks 802 move while driving the round block 801 to move in the direction of the first spring 406, so that the round block 801 abuts against the side wall of the clamping block 403, thereby squeezing the clamping block 403 to move in the same direction. While the two sets of clamping blocks 403 move, the two ends of the collagen thread 9 are driven to move in opposite directions, tightening the middle part of the collagen thread 9 at both ends, thereby improving the stability of the cut part of the collagen thread 9, thereby improving the cutting accuracy and efficiency of the entire cutting device;

[0054] Then the cutter 7 abuts against the plane of the inclined block 802, and the cutter 7 continues to move downward until the protrusion 505 abuts against the inner wall of the vertical groove 303. At this time, the cutter 7 contacts the middle part of the clamped ends of the collagen line 9 and cuts the middle part, completing the operation.

[0055] It is worth noting here that the interior of the handle 1 contains a wire pushing structure for facilitating the pushing of the collagen wire 9 out of the interior of the needle tube 2, thereby ensuring that the collagen wire 9 can be accurately and unobstructedly implanted into a predetermined position, such as an acupuncture point or tissue. The above belongs to the prior art.
