[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. 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.
[0032] like Figure 1-8 As shown, in some illustrative embodiments, a fascia knife is provided, including: a blade assembly 100, a fastener 200, and a gripper 300.
[0033] The blade assembly 100 includes multiple blades, all made of high-quality materials to ensure durability and comfort, such as stainless steel and silver. The shape and size of the blades vary depending on the treatment area to meet different treatment needs. Each blade has three locking holes 110 arranged in a triangle. In this embodiment, "triangular arrangement" means that the three locking holes 110 are located at the three vertices of an equilateral triangle, that is, the spacing between adjacent locking holes 110 is consistent, and their diameters are consistent.
[0034] The locking hole 110 is designed to press and fix the blade to the bottom of the holder 300 via the fastener 200, ensuring a secure connection between the blade and the holder 300. Because the locking holes 110 on the blade are arranged in a triangular pattern, the user can adjust the angle of the holder 300 by selecting any two locking holes 110 for use according to treatment needs, thus improving usability.
[0035] like Figure 2-4 As shown, the blade assembly 100 includes an M-shaped blade, which is used to relax large muscle groups, such as the back muscles and trapezius muscles. The M-shaped blade includes an arc-shaped portion 111 and force-bearing portions 112 located at both ends of the arc-shaped portion 111. The force-bearing portions 112 are smoothly connected to the arc-shaped portion 111, and three locking holes 110 arranged in a triangle are provided on the force-bearing portion 112. In use, the arc-shaped portion 111 contacts the skin, and its curved surface can better conform to different structures of the human body, such as the contours of muscles and fascia lines. The force-bearing portions 112 are clamped between the fastener 200 and the bottom of the gripper 300.
[0036] like Figure 5As shown, the blade assembly 100 also includes a bat knife for treating forearm fascia release. The bat knife includes an arc-shaped blade 113, with two arc-shaped notches 114 on one side. This notch shape better adapts to the curvature of the forearm, such as the edges of tendons and muscles, thereby effectively releasing the fascia. The arc-shaped blade 113 has three triangularly arranged keyholes 110 between the two arc-shaped notches 114.
[0037] like Figure 6 As shown, the scalpel assembly 100 also includes a scanning blade 115, used to probe the direction and depth of the fascia, preparing for subsequent treatment. One side of the scanning blade 115 has a straight edge, facilitating linear movement along the direction of the fascia during probes, helping therapists accurately identify the direction of the fascial lines. The other side of the scanning blade 115 has a curved edge, which can better adapt to different curvatures of the body. Three triangularly arranged keyholes 110 are provided on the scanning blade 115 near both ends.
[0038] The fastening member 200 consists of a support plate 210 and two locking pins 220 disposed on the support plate 210. The distance between the two locking pins 220 is the same as the distance between the lock holes 110. A locking groove 230 is formed on the side of the locking pin 220. The support plate 210 is used to press the blade against the bottom of the holder 300. The locking pins 220 and the locking groove 230 are used to cooperate with the holder 300 to fix the blade.
[0039] The gripper 300 is for the user to hold in order to operate the blade. The gripper 300 includes: a housing 310, a locking rod 320, a power unit 330, a rubber pad 350, and a handle 360.
[0040] A handle 360 is mounted on the housing 310. Both the housing 310 and the handle 360 are typically made of durable and easy-to-clean materials, such as plastic or metal, and have a non-slip surface treatment to improve grip stability. A guide channel 340 is provided within the housing 310, providing a sliding path for the locking rods 320, allowing them to smoothly engage with the locking pins 220. There are two locking rods 320, symmetrically arranged within the guide channel 340, each engaging with one of the two locking pins 220.
[0041] The power assembly 330 is used to drive the locking rods 320 to move laterally. Specifically, the power assembly 330 drives the two locking rods 320 to move laterally in a direction away from each other, so that the outer ends of the two locking rods 320 are respectively embedded in the locking grooves 230 opened on the two locking pins 220.
[0042] A rubber pad 350 is provided at the bottom of the housing 310, and two locking channels 370 are provided at the bottom of the grip.
[0043] In use, place the blade at the bottom of the holder 300, ensuring that the locking hole 110 on the blade is aligned with the locking channel 370. Then, the locking pin 220 passes through the locking hole 110 and extends into the locking channel 370. The power unit 330 actuates, driving the locking rod 320 to move laterally so that the outer end of the locking rod 320 is embedded in the locking groove 230, fixing the fastener 200. This allows the blade to be clamped between the support plate 210 and the rubber gasket 350 at the bottom of the holder, achieving a stable connection. The connection is stable, the operation is simple, and the blade can be easily replaced. This design makes the use of the fascia knife more efficient, safe, and user-friendly.
[0044] The power assembly 330 includes: a pusher 331, a stud 332, a nut 333, a lower open sleeve 334, an operating turntable 335, and a bearing 336.
[0045] The inner end of the locking rod 320 has a first inclined surface 321, and the bottom end of the push wheel 331 has a second inclined surface 3311 with the same inclination angle as the first inclined surface 321. The first inclined surface 321 and the second inclined surface 3311 are in contact with each other. The stud 332 is set on the top of the push wheel 331, and the nut 333 is sleeved on the stud 332 and threadedly connected to the stud 332. The nut 333 and the stud 332 form a ball screw transmission mechanism. When the nut 333 rotates, it drives the stud 332 to move downward. The first inclined surface 321 pushes the second inclined surface 3311, causing the locking rod 320 to move outward until the outer end of the locking rod 320 is embedded in the locking groove 230, thereby fixing the fastener 200 to the bottom of the holder 300, thus completing the fixation of the blade.
[0046] The inner ring of bearing 336 is connected to nut 333, and the outer ring of bearing 336 is connected to housing 310, ensuring stable rotation of nut 333. The bottom end of lower open sleeve 334 is connected to the upper end face of nut 333, and the top end of stud 332 extends into lower open sleeve 334, providing space for stud 332 to move. Operating turntable 335 is located at the top end of lower open sleeve 334. A recessed groove 380 is formed on the upper surface of housing 310, and operating turntable 335 is located within the recessed groove 380. Preferably, operating turntable 335 is mounted within the recessed groove 380 via bearings. When the user rotates operating turntable 335, the rotation of operating turntable 335 causes lower open sleeve 334 to rotate, which in turn causes nut 333 to rotate, facilitating operation.
[0047] The upper wall of the locking groove 230 has a third inclined surface 231, and the outer end of the locking rod 320 has a fourth inclined surface 322 with the same inclination angle as the third inclined surface 231. When the outer end of the locking rod 320 is gradually inserted into the locking groove 230, the fourth inclined surface 322 comes into contact with the third inclined surface 231, pushing the third inclined surface 231 to have an upward tendency, which also makes the locking pin 220 have a tendency to extend further into the locking channel 370, thereby making the locking member 200 further press the blade. At this time, the rubber gasket 350 deforms, increasing the locking tightness and further ensuring the stability of the blade.
[0048] The inner end of the locking rod 320 is also provided with a guide block 323. A groove 341 is opened on the lower channel wall of the guide channel 340. The guide block 323 is located in the groove 341. A return spring 390 is set in the groove 341. The two ends of the return spring 390 are respectively connected to the inner ends of the two locking rods 320. When it is necessary to replace the blade, the operating turntable 335 is rotated in the opposite direction. The nut 33 is driven to rotate in the opposite direction through the lower open sleeve 334. At this time, the stud 332 moves upward and no longer limits the locking rod 320. The two locking rods 320 retract into the guide channel 340 under the action of the return spring 390. At this time, the locking stud 220 can be pulled out, the fastener 200 can be removed, and the next blade can be replaced.
[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
