Description

Technical Field

[0001] This utility model belongs to the field of SMAS fascia lifting technology, specifically relating to a rotary snap-lock tightening device for SMAS fascia lifting. Background Technology

[0002] The SMAS layer, scientifically known as the superficial musculoskeletal system, is located approximately 4.5 mm deep within the skin, between subcutaneous fat and muscle. It is a musculoskeletal fascia surrounded by a fibrous sheath, directly connecting bones and muscles. In cosmetic anti-aging procedures, many techniques work by lifting the SMAS layer to achieve wrinkle reduction and enhance anti-aging effects.

[0003] During SMAS fascia lift surgery, 2-0 mousse sutures are used for fixation. The SMAS fascia is fixed in two locations. The first fixation suture directly fixes the thicker preauricular fascia to the connection point on the earlobe. The second fixation suture is fixed behind the zygomatic arch periosteum. Then, 2-0 PDS or 2-0 Vicryl sutures are used to cover this area and are fixed between the two mousse sutures. If the SMAS fascia in the neck has sufficient mobility, these fixation sutures can be placed as low as the mastoid region. SMAS suspension can lift the jawline, neck, and nasolabial folds. The degree of improvement in nasolabial folds and the midface depends on the extent of SMAS layer mobilization.

[0004] During the surgery, when tightening the fascia layer with the fixation sutures, it is necessary to pull the fixation sutures to maintain the tightening force. Secondly, during postoperative recovery, in order to reduce the pulling on the sutures at the auricle, a lifting suture is set to lift and tighten the fixation sutures during the operation and the sutures at the auricle sutures after the operation. As the operation progresses, the lifting sutures need to be tightened, which makes it difficult to adjust. After the operation, the lifting sutures at the auricle may loosen due to recovery and other factors, affecting the lifting and support effect. Utility Model Content

[0005] The purpose of this invention is to provide a rotary snap-locking device for SMAS fascia lifting, which can solve the above-mentioned technical problems.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a rotary buckle-type tightening device for SMAS fascia lifting, including a torsion mechanism and an outer cover mechanism. The outer cover mechanism is provided with a transmission mechanism connected to the torsion mechanism. The torsion mechanism is connected to a winding mechanism provided in the outer cover mechanism through the transmission mechanism. The winding mechanism is connected to a buckle mechanism provided on the lower side of the outer cover mechanism.

[0008] The torsion mechanism includes a torsion cap and three locking blocks evenly distributed around the bottom surface of the torsion cap. Arc-shaped locking plates are respectively provided on the upper side of the opposite sides of the three locking blocks. The inner bottom surface of the torsion cap is formed with three circumferentially distributed insertion slots. The three insertion slots are respectively located between the three locking blocks and on the circumference of the three locking blocks.

[0009] The transmission mechanism includes a transmission disc fitted inside a torsion cap, the bottom surface of the transmission disc is provided with three insertion posts that are inserted into the insertion slot, and the upper surface of the transmission disc is provided with an inner insertion block.

[0010] The winding mechanism includes a rotating disk and four circumferentially distributed winding plates disposed on the bottom surface of the rotating disk. The upper surface of the rotating disk is provided with a socket plate that engages with the inner insert block.

[0011] The aforementioned rotary snap-lock tightening device for SMAS fascia lifting involves threading the lifting cable through the threading hole on the housing and through the straight gap between the four winding plates. The lifting cable, passing through the device, is then secured at the head. By rotating the torsion cap, the torsion cap engages with the insertion post through the insertion slot, causing the transmission disc to rotate synchronously. Simultaneously, the transmission disc drives the inner insertion block to rotate the rotating disc on the winding mechanism, causing the rotating disc to rotate the four winding plates. This rotation of the winding plates causes the lifting cable to wind around their outer circumference, thereby tightening the lifting cable. At the same time, the rotation of the transmission disc causes the curved teeth on the ligament plate to slide over the curved tooth groove ring, allowing the curved teeth to rebound due to the ligament plate's resilience and lock into the curved tooth groove on the curved tooth groove ring in real time, thus creating real-time braking for the transmission disc and the indirectly connected winding plates.

[0012] Preferably, the outer cover mechanism includes a cover that is inserted into the inner circumferential surface of the torsion cap. A curved tooth groove ring is provided on the upper side of the inner circumferential surface of the cover. Three flexible plates are evenly provided on the outer circumferential surface of the transmission disk. The three flexible plates are in the shape of a fifth circle. A connecting block that connects to the outer circumferential surface of the transmission disk is integrally provided on one side of the flexible plate. Two curved teeth that mesh with the curved tooth groove ring on the other side of the flexible plate are provided.

[0013] Preferably, the outer peripheral surface of the cover is inserted into the inner peripheral surface of the torsion cap, and three equally distributed locking blocks are provided on the upper side of the outer peripheral surface of the cover, and the inner peripheral surface of the torsion cap is provided with a locking ring that engages with the locking blocks.

[0014] Preferably, the cover is provided with four circumferentially symmetrically distributed threading holes, and the outer circumferential surface of the cover is provided with four ear plates evenly distributed between two adjacent threading holes.

[0015] Preferably, the buckling mechanism includes an inner buckle plate that inserts into the lower side of the cover, the upper surface of the inner buckle plate is provided with four cover rings that fit into the winding plate, and the bottom surface of the inner buckle plate is provided with a sponge pad.

[0016] Preferably, the inner buckle plate is provided with a buckling mechanism, which includes two buckling plates and two buckling plates that are inserted and matched. The two buckling frames are symmetrically arranged on the lower side of the outer peripheral surface of the cover.

[0017] Preferably, two fixing plates are symmetrically arranged on the lower side of the outer periphery of the inner buckle plate. Each of the two fixing plates has a buckle plate at its opposite ends. Triangular blocks are symmetrically arranged on the upper side of each of the two buckle plates, and the triangular blocks are engaged with the buckle frame.

[0018] Preferably, the transmission disk is provided with a pressing mechanism, which includes an adjusting shaft and an elastic element. The adjusting shaft is fitted and matched with a sleeve hole formed on the torsion cap. The bottom surface of the inner insert block is provided with an elastic element through a formed circular groove. The lower side of the elastic element contacts the inner bottom surface of the insertion hole on the insertion disk.

[0019] Preferably, the overall thickness of the torsion cap fitted onto the cover is between 5-6 mm, and the diameter of the cover is between 1.0-1.5 cm.

[0020] The beneficial effects are:

[0021] 1. This utility model involves passing the lifting cable through the threading hole on the cover and then through the four winding plates on the winding mechanism. The lifting cable is then secured to the head. The torsion cap can be rotated or the inner insert block on the transmission mechanism can be driven to rotate the insert plate and the four winding plates. This causes the lifting cable to be tightened by the rotation and winding of the four winding plates. At the same time, the curved teeth on the transmission plate slide over the curved tooth groove ring, thereby forming a locking and braking effect between the curved teeth and the curved tooth groove ring. This provides a real-time tightening and fixing effect for the lifting cable, improving the tightening adjustment effect.

[0022] 2. This utility model, through the pressing mechanism, allows the adjusting shaft to be pressed down, causing the curved teeth on the transmission disc to move down and disengage from the curved tooth groove ring. This allows the lifting line wound on the winding plate to be released and the tension adjustment to be adjusted.

[0023] 3. This utility model uses five mechanisms for insertion and snap-fit, which facilitates its assembly and improves the efficiency of disassembly, maintenance and replacement in the later stage. Attached Figure Description

[0036] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0037] like Figure 1-10As shown, a rotary buckle tightening device for SMAS fascia lifting includes a torsion mechanism 1 and an outer cover mechanism 4. The outer cover mechanism 4 is provided with a transmission mechanism 2 connected to the torsion mechanism 1. The torsion mechanism 1 is connected to a winding mechanism 3 provided in the outer cover mechanism 4 through the transmission mechanism 2. The winding mechanism 3 is connected to a buckle mechanism 5 provided on the lower side of the outer cover mechanism 4. The torsion mechanism 1, transmission mechanism 2, winding mechanism 3, outer cover mechanism 4 and buckle mechanism 5 are all integrally molded from plastic.

[0038] The torsion mechanism 1 includes a torsion cap 101 and three locking blocks 103 evenly distributed around the bottom surface of the torsion cap 101. Arc-shaped locking plates 104 are respectively provided on the upper side of the opposite sides of the three locking blocks 103. The inner bottom surface of the torsion cap 101 is formed with three circumferentially evenly distributed insertion slots 105. The three insertion slots 105 are respectively located between the three locking blocks 103 and on the circumference of the three locking blocks 103.

[0039] The transmission mechanism 2 includes a transmission disc 201 fitted inside the torsion cap 101. The bottom surface of the transmission disc 201 is provided with three insertion posts 205 that are inserted into the insertion slot 105. The upper surface of the transmission disc 201 is provided with an inner insertion block 204.

[0040] The winding mechanism 3 includes a rotating disk 301 and four circumferentially distributed winding plates 303 disposed on the bottom surface of the rotating disk 301. The upper surface of the rotating disk 301 is provided with an insertion hole disk 302 that engages with the inner insertion block 204.

[0041] As an optional implementation, the outer cover mechanism 4 includes a cover 401 that is inserted into the inner circumferential surface of the torsion cap 101. A curved toothed groove ring 402 is provided on the upper side of the inner circumferential surface of the cover 401. Three flexible plates 202 are evenly provided on the outer circumferential surface of the transmission disk 201. The three flexible plates 202 are shaped like one-fifth of a circle. A connecting block that connects to the outer circumferential surface of the transmission disk 201 is integrally provided on one side of the flexible plate 202. Two curved teeth 203 that mesh with the curved toothed groove ring 402 are provided on the other side of the flexible plate 202. The distance between the three flexible plates 202 and the outer circumferential surface of the transmission disk 201 is set to be inserted into the locking block 103. This allows the locking block 103 to form an arched support for the flexible plates 202, improving the rebound effect of the flexible plates 202 driving the curved teeth 203.

[0042] See attached document Figure 9The outer peripheral surface of the cover 401 is inserted into the inner peripheral surface of the torsion cap 101. Three equally distributed locking blocks 404 are provided on the upper side of the outer peripheral surface of the cover 401. The inner peripheral surface of the torsion cap 101 is provided with a locking ring 102 that engages with the locking blocks 404. The distance between the locking ring 102 and the inner top surface of the torsion cap 101 is set to 1.1 times the height of the locking block. This allows the locking block to slide through and lock into the torsion cap 101 after being squeezed by the locking ring 102, and prevents it from detaching due to the locking of the locking ring 102. At the same time, it does not affect the rotation of the torsion cap 101 after it is fitted with the cover 401. The outer peripheral surface of the torsion cap 101 is provided with multiple anti-slip ridges 106, thereby improving the anti-slip effect during torsion.

[0043] Furthermore, the cover 401 is provided with four circumferentially symmetrically distributed threading holes 403, and the outer circumferential surface of the cover 401 is provided with four ear plates 405 evenly distributed between two adjacent threading holes 403. The cover 401 can be constrained to rotate by pinching the ear plates 405, thereby facilitating the rotation adjustment of the torsion cap 101.

[0044] See attached document Figure 10 The buckling mechanism 5 includes an inner buckle plate 501 that inserts into the lower inner side of the cover 401. The upper surface of the inner buckle plate 501 is provided with four cover rings 502 that insert into the winding plate 303. The cover rings 502 can restrict the lifting line wound on the winding plate 303 to prevent it from detaching from the winding plate 303 and affecting the winding and tightening adjustment. The bottom surface of the inner buckle plate 501 is provided with a sponge pad 503. This arrangement allows the sponge pad 503 to contact the head skin when the device is tightened and fixed, improving comfort.

[0045] Furthermore, the inner buckle plate 501 is provided with a buckling mechanism, which includes two buckling plates 505 and a buckling frame 406 that is inserted and engaged with the two buckling plates 505. The two buckling frames 406 are symmetrically arranged on the lower side of the outer peripheral surface of the cover 401, so that when the buckling plate 505 is pressed against the buckling frame 406 by its own toughness, the buckling plate 505 tilts and slides over the inner side of the buckling frame 406 to form a buckling state.

[0046] Furthermore, two fixing plates 504 are symmetrically arranged on the lower side of the outer periphery of the inner buckle plate 501. Each of the two fixing plates 504 has a snap-fit ​​plate 505 at its opposite ends. Triangular blocks are symmetrically arranged on the upper side of the two snap-fit ​​plates 505, and the triangular blocks engage with the snap-fit ​​frame 406. This allows the inner buckle plate 501 to engage with the lower interior of the cover 401, and the inner buckle plate 501 drives the snap-fit ​​plate 505 on the fixing plate 504 to press against the snap-fit ​​frame 406 to form a snap-fit, thereby fixing the inner buckle plate 501 and the cover 401 together.

[0047] Furthermore, a pressing mechanism is provided on the transmission disc 201, and the pressing mechanism includes an adjusting shaft 206 and an elastic element 207 provided on the transmission disc 201. The adjusting shaft 206 is fitted and matched with the sleeve hole 107 formed on the torsion cap 101. The bottom surface of the inner insert block 204 is provided with an elastic element 207 through a formed circular groove. The elastic element 207 is a spring. The lower side of the elastic element 207 contacts the bottom surface of the insertion hole on the insertion plate 302. A cross groove is opened on the upper surface of the adjusting shaft 206. The adjusting shaft 206 is rotated by a flathead or Phillips screwdriver, thereby driving the transmission mechanism 2 to drive the winding mechanism 3, so that the winding mechanism 3 rotates to tighten the lifting line.

[0048] By pressing down on the adjusting shaft 206, the adjusting shaft 206 is forced to move downward, which at the same time drives the transmission disc 201 and the curved tooth 203 to move downward and disengage from the meshing connection with the curved tooth groove ring 402. At the same time, the downward movement of the transmission disc 201 squeezes the elastic element 207. Thus, the relaxation adjustment can be achieved by pulling the lifting line wound on the winding plate 303.

[0049] Furthermore, the overall thickness of the torsion cap 101 fitted onto the cover 401 is set between 5-6mm, and the diameter of the cover 401 is set between 1.0-1.5cm, which can reduce the size and weight of the device, thereby reducing the downward impact during horizontal lifting during surgery.

[0050] Using the above structure, the lifting cable is passed through the threading hole 403 on the cover 401 and through the straight gap between the four winding plates 303. The lifting cable passing through the device is then tied to the head. By rotating the torsion cap 101, the torsion cap 101 engages with the insertion post 205 through the insertion slot 105, driving the transmission disc 201 to rotate synchronously. At the same time, the transmission disc 201 drives the inner insertion block 204 to drive the rotating disc 301 on the winding mechanism 3 to rotate, causing the rotating disc 301 to drive the four winding plates 303 to rotate. This allows the winding plates 303 to rotate and drive the lifting cable to wind around their outer circumference, thereby tightening the lifting cable. At the same time, when the transmission disc 201 rotates, the curved teeth 203 on the flexible plate 202 slide over the curved tooth groove ring 402, causing the curved teeth 203 to rebound due to the toughness of the flexible plate 202 and get stuck in the curved tooth groove on the curved tooth groove ring 402 in real time, thereby forming real-time braking on the transmission disc 201 and the indirectly connected winding plate 303.

[0051] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
