Abstract
Description
Technical Field
[0001] The present invention relates to a chiropractic spinal correction and muscle relaxation device for chiropractic treatment to correct and relax the misalignment of the skeleton and muscle tension that cause stiff shoulders, low back pain, etc.
Background Art
[0002] Skeletal misalignment and muscle tension are caused by various factors. It may be caused by external impacts such as accidents or injuries, or it may be caused by lifestyle habits or the content of daily work. Such skeletal misalignment and muscle tension cause stiff shoulders and low back pain. Furthermore, it may also appear as pain in the knees or ankle joints, or pain in the back or elbows.
[0003] When correcting and relaxing the skeletal misalignment and muscle tension that cause stiff shoulders and low back pain through chiropractic treatment, conventionally, the practitioner performed the treatment using their own fingers and arms, which required physical strength and had a large individual difference.
[0004] The following patent document discloses a chiropractic device that can correct skeletal misalignment by pressing the tip of a protruding member against the treatment point and driving an electric impact generating mechanism provided in the main body to generate an axial impact force on the protruding member.
[0005] However, since the above chiropractic device applies an axial impact force to the protruding member by an electric impact generating mechanism, it is difficult to apply a delicate force adjustment to the treatment point of the patient. Even if the skeletal misalignment can be corrected, it is difficult to relax the muscle tension.
[0006] Also, in ancient China, there was a kind of health method passed down in Taoism called "Kou Kou", in which a dedicated tool with a specific wooden shape was used to tap the body to activate the "Qi" that constantly changes like the "Yao" in the body and its flow, and enhance yang energy. However, it was only carried out in a very limited range with secret techniques.

[0007] [Patent Document 1] Japanese Patent Publication No. 2020-178929 [Overview of the Initiative] [Problems that the invention aims to solve]
[0008] The purpose of this invention is to provide a set of spinal correction and muscle relaxation tools for osteopathy that allows for the correction and relaxation of skeletal misalignments and muscle tension that cause neck and shoulder stiffness, lower back pain, knee and ankle joint pain, or back and elbow pain, using simple tools rather than relying solely on human strength. [Means for solving the problem]
[0009] To achieve the above objective, the set of chiropractic spinal correction and muscle relaxation tools according to claim 1 of the present invention is a set of chiropractic tools for correcting and relaxing misalignment of the spinal skeleton and tension in the muscles located on both sides of the spinal skeleton, which are the causes of neck and shoulder stiffness and lower back pain, and is characterized by comprising: multiple types of wooden hammering rods, the contact surface of the tip that is applied to the treatment point of the patient is curved, and the receiving surface of the handle that strikes the contact surface of the tip is flat and has an elastic cushioning material attached to its surface, and an angle measuring ruler for measuring the left-right imbalance of muscles centered on the spine caused by the misalignment of the spinal skeleton and tension in the muscles located on both sides of the spinal skeleton.
[0010] Furthermore, the set of chiropractic spinal correction muscle relaxation tools according to claim 2 of the present invention is a set of chiropractic spinal correction muscle relaxation tools according to claim 1, characterized in that the striking rod is composed of four types: a branched type in which the tip extending from the rectangular handle is branched in a U shape and the contact surface is hemispherical; a flat plate type in which the tip extending from the rectangular handle is wedge-shaped and the axial cross-sectional shape of the contact surface is arc-shaped; a cylindrical rod type in which the tip extending from the cylindrical rod-shaped handle is wedge-shaped and the axial cross-sectional shape of the contact surface is arc-shaped; and a conical rod type in which the contact surface of the tip of the conical rod-shaped handle is hemispherical.
[0011] Furthermore, the set of chiropractic spinal correction muscle relaxation tools according to claim 3 of the present invention is the set of chiropractic spinal correction muscle relaxation tools according to claim 1 or 2, characterized in that the cushioning material is high-density plastic or an elastic pad. [Effects of the Invention]
[0012] This invention provides the following effects.
[0013] In other words, the spinal correction and muscle relaxation tool for osteopathy according to the present invention, which has the above configuration, is an improved version of a special wooden tool used in Chinese Taoism to promote the flow of "qi," and is used in osteopathic treatment. Therefore, it can correct and relax the misalignment of the spinal skeleton and the tension of the muscles located on both sides of the spinal skeleton that are causing neck and shoulder stiffness and lower back pain, without putting any strain on the patient.
[0014] Furthermore, by measuring the left-right imbalance centered on the spine, caused by the misalignment of the spinal skeletal structure and the tension of the muscles located on either side of the spinal skeletal structure, using an angle measuring ruler before and after treatment, it is possible to optimally correct and relax the skeletal misalignment and muscle tension without overdoing or underdoing it.
[0015] Furthermore, since a buffer material with elasticity is attached to the striking surface of the striking rod, the strong strike of the hammer does not directly reach the patient at the treatment point, but is transmitted as a soft impact, so that the displacement of the spinal skeleton and the tension of the muscles located on both sides of the spinal skeleton can be effectively corrected and relaxed. Moreover, since the striking sound when hitting the striking surface with the hammer is absorbed by the buffer material, it is possible to prevent it from being annoying to the patient.

[0019] The whole-body spinal correction muscle relaxation tool set according to the present invention is composed of four types of wooden percussion rods, namely a bifurcated percussion rod, a flat percussion rod, a cylindrical rod-shaped percussion rod, and a conical rod-shaped percussion rod, and an angle measuring rule.
[0020] As shown in the perspective view of FIG. 1, the bifurcated percussion rod 10 according to the present invention is made of wood. The tip 12 extending from the hand part 11 having a wide rectangular shape toward the side hitting the patient's treatment point is bifurcated in a U shape. The contact surface 13 of the tip 12 where the patient's treatment point hits is a hemispherical curved surface shape with a large curvature. A cushioning material 15 formed of rubber is adhered to the impact surface 14 on the operator side of the hand part 11 where the hammer hits. Regarding the size of the bifurcated percussion rod 10, the length L1 from the contact surface 13 to the impact surface 14 is preferably 9 to 13 cm.
[0021] As shown in the perspective view of FIG. 2, the flat percussion rod 20 according to the present invention is made of wood. The tip 22 extending from the hand part 21 having a rectangular shape toward the side hitting the patient's treatment point is a flat plate shape with a wide plane and is wedge-shaped with the thickness becoming thinner from both sides toward the contact surface 23 at the tip. The contact surface 23 of the tip 22 where the patient's treatment point hits is a curved surface shape with an arcuate cross-sectional shape in the axial direction. A cushioning material 25 formed of rubber is adhered to the impact surface 24 on the operator side of the hand part 21 where the hammer hits. Regarding the size of the flat percussion rod 20, the length L2 from the contact surface 23 to the impact surface 24 is preferably 13 to 17 cm.
[0022] As shown in the perspective views of FIGS. 3 and 4, the cylindrical rod-shaped percussion rod 30 according to the present invention is made of wood. The hand part 31 having a cylindrical shape with the same thickness and extending straight is long, and the tip 32 extending toward the side hitting the patient's treatment point is wedge-shaped with the thickness becoming thinner from both sides toward the contact surface 33 at the tip. The contact surface 33 of the tip 32 where the patient's treatment point hits is a curved surface shape with an arcuate cross-sectional shape in the axial direction. A cushioning material 35 formed of rubber is adhered to the impact surface 34 on the operator side of the hand part 31 where the hammer hits. Regarding the size of the cylindrical rod-shaped percussion rod 30, the length L3 from the contact surface 33 to the impact surface 34 is preferably 14 to 18 cm.
[0023] As shown in the perspective view of Figure 5, the conical rod-type hammering rod 40 according to the present invention is made of wood, and a constricted portion 46 is formed at the tip of the conical handle portion 41 which gradually tapers towards the end. The conical tip portion 42 extends from the constricted portion 46 toward the contact surface 43 that strikes the patient's treatment point. The contact surface 43 that strikes the patient's treatment point has a hemispherical curved shape with a large curvature. A cushioning material 45 made of rubber is attached to the impact surface 44 on the practitioner's side of the handle portion 41 that strikes the hammer. The size of the conical rod-type hammering rod 40 is preferably such that the length L4 from the contact surface 43 to the impact surface 44 is 9 to 13 cm.
[0024] As shown in the front view of Figure 6, the angle measuring ruler 60 has an arc-shaped passage 62 through which a spherical body 61 moves. The central part 66 of the arc is defined as 0 degrees, and scales 63 are marked symmetrically on both sides starting from that point. A semicircular recess 65 is formed on the bottom surface 64, and when the patient's spine is aligned with the recess 65, the spherical body 61 moves within the passage, and by reading the scale 63 at the position it has moved to, it is possible to measure the left-right imbalance around the spine caused by the displacement of the spinal skeleton and the tension of the muscles located on both sides of the spinal skeleton.
[0025] As described above, the practitioner aligns the angle measuring ruler 60 with the patient's spine and measures the left-right imbalance centered on the spine caused by the misalignment of the spinal skeleton and the tension of the muscles located on both sides of the spinal skeleton. After confirming the treatment points using their fingers and arms, they use the hammering rods (10, 20, 30, 40) to apply the contact surfaces (13, 23, 33, 43) of the tip (12, 22, 32, 42) to the treatment points and strike the cushioning material (15, 25, 35, 45) attached to the surface of the impact surface (14, 24, 34, 44) of the handle (11, 21, 31, 41) with the hammer to correct and relax the skeletal misalignment and muscle tension. Since measurements are taken with the angle measuring ruler 60 even during the treatment, it is possible to perform the correction and relaxation of skeletal misalignment and muscle tension optimally without overdoing or underdoing. Furthermore, the type of striking stick (10, 20, 30, 40) to be used will be selected by the practitioner as appropriate based on the patient's symptoms.
