[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0026] Embodiment 1: like Figures 1 to 4 As shown, the present invention provides a bone trauma therapeutic instrument for orthopedic treatment, comprising a main unit, and a coupling plate 1 and a heating seat 2 connected to the main unit. The heating seat 2 is attached to the treatment part to heat and keep the treatment part warm, and the coupling plate 1 is adjustable and supported on the heating seat 2 to provide electromagnetic therapy for the treatment part.

[0027] A sink groove is provided at the center of the upper surface of the heating seat 2, and a ball groove 21 is provided at the bottom of the sink groove. A ball head 31 is fixed to the lower end of the adjusting column 3, and the ball head 31 is installed in the ball groove 21. The split pressure cover 22 is fixed to the sink groove by bolts; the inner side of the pressure cover 22 is a spherical surface, and is pressed on the ball head 31 to prevent the ball head 31 from escaping from the ball groove 21. The adjusting column 3 is connected to the ball groove 21 by a ball joint through the ball head 31, and the orientation and angle can be freely rotated to adjust. The locking component 4 is arranged between the ball head 31 and the ball groove 21, and is used to lock the relative position of the ball head 31 and the heating seat 2. A through hole 11 is provided in the center of the coupling disk 1, and the through hole 11 is sleeved outside the adjusting column 3; the coupling disk 1 is installed with a sliding component 5 in the through hole 11, and the sliding component 5 slides axially along the adjusting column 3. The angle and height adjustment of the coupling disk 1 relative to the heating seat 2 can be realized by the locking component 4 and the sliding component 5, so as to provide accurate and efficient electromagnetic therapy.

[0028] Combination Figures 1 to 5As shown in the figure, a pair of symmetric first through grooves 32 are formed on the circumferential surfaces of the adjusting column 3 and the ball head 31. The first through grooves 32 penetrate from the upper end of the adjusting column 3 to the lower end of the ball head 31. Two communication holes 34 arranged in parallel are formed in the adjusting column 3; the communication holes 34 are perpendicular to the axis of the adjusting column 3, and both ends of the communication holes 34 communicate with the first through grooves 32 on both sides. Two locking members 41 are respectively fitted and installed in the first through grooves 32 on both sides, and the elastic rod 42 is inserted into the communication hole 34. Both ends of the elastic rod 42 abut against the locking members 41 to provide an elastic force for the two locking members 41 to move outward from the first through grooves 32.

[0029] The locking member 41 mainly includes a semi-circular semi-circular portion 411 at the lower end and a straight rod-shaped straight rod portion 412 at the upper end. The semi-circular portion 411 is fitted and installed in the first through groove 32 on the ball head 31, and the outer side surface of the semi-circular portion 411 is an arc surface that mates with the ball groove 21. Sharp protrusions are evenly distributed on the arc surface, and grooves are also evenly distributed on the inner surface of the ball groove 21. When the semi-circular portion 411 fits with the ball groove 21, the protrusions cooperate with the grooves to realize the positioning of the locking member 41 and the ball groove 21, thereby restricting the sliding of the ball head 31 in the ball groove 21, and finally realizing the relative fixation of the adjusting column 3 and the heating base 2.

[0030] The straight rod portion 412 is fitted and installed in the first through groove 32 on the adjusting column 3. A tapered groove is formed at a position on the inner side surface of the straight rod portion 412 opposite to the elastic rod 42. The end of the elastic rod 42 is spherical and is fitted and inserted into the tapered groove on the corresponding straight rod portion 412. The two elastic rods 42 are in a compressed state, and thus can push the two locking members 41 outward. The end cover 43 is fixed to the upper end of the adjusting column 3. A stopper 431 extending downward is provided around the end cover 43, and the stopper 431 is fitted and embedded in the upper end of the first through groove 32. The stopper 431 abuts against the outer side of the upper end of the locking member 41 to prevent the upper end of the locking member 41 from disengaging from the first through groove 32.

[0031] Working principle: In the normal state, the two elastic rods 42 push the two locking members 41 outward. The upper ends of the locking members 41 abut against the stopper 431, and the lower ends of the locking members 41 abut against the ball groove 21, realizing the locking of the adjusting column 3 and the heating base 2. When the locking member 41 is pushed inward, the inner side of the locking member 41 fits with the bottom of the first through groove 32, and at the same time, the semi-circular portion 411 at the lower end of the locking member 41 also disengages from the ball groove 21, realizing the unlocking of the adjusting column 3 and the heating base 2. At this time, the angle between the adjusting column 3 and the heating base 2 can be freely changed, that is, the angle of the coupling disc 1 relative to the heating base 2.

[0032] Embodiment 2: Based on the above Embodiment 1, this embodiment provides a sliding assembly 5, which can realize the adjustment of the relative height between the coupling disc 1 and the heating base 2 while adjusting the angle of the coupling disc 1 relative to the heating base 2.

[0033] Combined withFigure 2 , and Figures 4 to 8 As shown in Figures 4 to 8 , the through hole 11 of the coupling disk 1 is sleeved outside the adjusting column 3. A pair of symmetric second through grooves 33 are also formed on the circumferential surface of the adjusting column 3. The two second through grooves 33 and the two first through grooves 32 are arranged staggeredly at 90°.

[0034] The sliding assembly 5 includes a pressure ring 55 fixed at the through hole 11 of the coupling disk 1. The pressure ring 55 is sleeved outside the adjusting column 3. The pressure ring 55 and the upper surface of the coupling disk 1 form an internally open annular groove. The elastic ring 51 is arranged in the annular groove between the upper side of the coupling disk 1 and the pressure ring 55. The elastic ring 51 is sleeved outside the adjusting column 3 and has a gap with the adjusting column 3 to facilitate the elastic deformation of the pressure ring 55. Two rollers 52 and two friction blocks 53 arranged staggeredly are fixed on the inner side wall of the elastic ring 51. The rollers 52 are correspondingly installed in the first through grooves 32 and are located outside the locking member 41. The friction blocks 53 are correspondingly installed in the second through grooves 33. One side of the friction block 53 close to the bottom of the second through groove 33 is a friction surface. When the friction block 53 contacts the second through groove 33 through the friction surface, the locking of the position of the friction block 53 and the second through groove 33 can be realized; the friction surface here and the bottom surface of the second through groove 33 can adopt the positioning form of the locking member 41 and the ball groove 21 in the first embodiment. A dial 54 is fixed at a position on the elastic ring 51 opposite to the roller 52. An avoidance groove 551 matched with the dial 54 is formed on the pressure ring 55. The dial 54 penetrates upward through the avoidance groove 551 to facilitate the operation of the dial 54; during use, the elastic ring 51 can be conveniently squeezed inward and slid up and down through the dials 54 on both sides.

[0035] Working principle: In the normal state, the elastic ring 51 has a certain deformation, providing a certain elasticity in the direction of the two friction blocks 53, that is, the elastic ring 51 squeezes and positions the two friction blocks 53 at the bottom of the second through groove 33, realizing the locking of the elastic ring 51 and the adjusting column 3, that is, the locking of the relative height of the coupling disk 1 and the heating base 2; at this time, the two rollers 52 are located in the first through grooves 32 and do not contact the locking member 41; When the dials 54 on both sides are squeezed inward, the elastic ring 51 deforms inward in the direction of the two rollers 52, pushing the rollers 52 to move inward and squeeze the locking member 41, so that the inner side of the locking member 41 fits with the bottom of the first through groove 32, thus realizing the unlocking of the locking member 41. At this time, the relative angle between the coupling disk 1 and the heating base 2 can be adjusted; at the same time, the inward deformation of the elastic ring 51 in the direction of the two rollers 52 also causes the elastic ring 51 to deform outward in the direction of the two friction blocks 53, and then the friction blocks 53 move outward (still remaining in the second through grooves 33), realizing the unlocking of the friction blocks 53 and the second through grooves 33. At this time, the elastic ring 51 can be slid up and down to adjust the relative height of the coupling disk 1 and the heating base 2; After the paddle 54 is released, the elastic ring 51 resets, the friction block 53 is pressed against the bottom of the second through groove 33 again, locking the height of the coupling disc 1; at the same time, the elastic rod 42 pushes the two locking members 41 outwards, and the semi-circular part 411 at the lower end of the locking member 41 is also pressed against the ball groove 21 again, locking the angle of the coupling disc 1.

[0036] Embodiment III: Based on the above Embodiment II, combined with Figures 1 to 4 As shown, the bottom of the coupling disc 1 has a groove, and the annular part extending downward around the periphery is used to install the electromagnetic coil. The heating base 2 is arranged in the groove at the bottom of the coupling disc 1 in a matching manner. The coupling disc 1 is in contact with the upper side of the heating base 2 at the lowest position. At this time, the bottom surface of the annular part around the coupling disc 1 is still higher than the bottom surface of the heating base 2.

[0037] The sponge gasket ring 6 is fitted and installed around the heating base 2 and can be removed or replaced according to requirements. The bottom surface of the sponge gasket ring 6 extends beyond the bottom surface of the heating base 2. A plurality of air permeable pipes 61 are evenly embedded in the sponge gasket ring 6. The air permeable pipes 61 communicate the outside of the sponge gasket ring 6 with the lower side of the heating base 2, and the air permeable pipes 61 can realize the air flow between the outside of the sponge gasket ring 6 and the lower part of the heating base 2. A plurality of air vent holes 23 are opened in the middle of the heating base 2. The air vent holes 23 are evenly distributed around the sunken groove at the center of the heating base 2 and penetrate through the heating base 2 up and down. The air vent holes 23 can realize the air flow between the lower part and the upper part of the heating base 2.

[0038] During operation, the heating base 2 is attached to the treatment site through the sponge gasket ring 6. The heating base 2 can be fixed by an elastic band or Velcro to provide stable support for the coupling disc 1; during the heating process of the heating base 2, the outside air forms a circulation channel through the air permeable pipes 61 and the air vent holes 23 to ensure the air flow at the treatment site and avoid sweating and water vapor generation.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
