Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

A3D printed children hip dislocation postoperative rehabilitation assistive device comprises a waist assistive device 1, a leg assistive device 2 and a foot assistive device 3.

The waist assistive device 1, the leg assistive device 2, and the foot assistive device 3 are each composed of a back panel and side panels on both sides, which are manufactured by 3D printing.

The back plate 101 of the waist assistive device and the back plate 201 of the leg assistive device are connected by a hinge 4, and the two side plates 102 of the waist assistive device and the two side plates 202 of the leg assistive device are connected by a rotary scale device 5.

The rotary scale device 5, as shown in fig. 4 to 6, includes an angle scale 503, a first connecting rod 501 connected to the waist assist device side plate 102, and a second connecting rod 502 connected to the leg assist device side plate 202, and the first connecting rod 501 and the second connecting rod 502 are rotatably fixed to the center of the angle scale 503 by a fitting. The first connecting rod 501 and the second connecting rod 502 are provided with angle display slots 504.

Referring to fig. 5, the first connecting rod 501 is long, one end of which is connected to the waist assistive device side plate 102, and the other end of which is circular with a hole in the middle. Referring to fig. 6, the second connecting rod 502 is a long strip, one end of which is connected to the leg auxiliary side plate 202, and the other end is a circular disc surface, a semi-circular side surface of the outer ring and a full-circular side surface of the inner ring, forming a semi-circular groove, the circular end of the first connecting rod 501 is installed in the semi-circular groove, at this time, the circular holes at the centers of the two are overlapped, and then overlapped with the circular hole at the center of the angle dial, the central shaft of the sleeving member is inserted therein, and a protective housing is provided at the inner side and the outer side. Thus, the first link 501 can rotate about the central axis of the socket, and can form a different angle with the second link 502. Meanwhile, the angle display grooves 504 formed in the two connecting rods can display the angle on the angle dial, so that the angle between the first connecting rod 501 and the second connecting rod 502 can be conveniently read and recorded.

The center of the angle dial 503 corresponds to the hinge 4 between the waist support back plate 101 and the leg support back plate 201. When the rotary scale 5 rotates, the hinge 4 is engaged with the back plate 101 of the waist assistant tool to make the back plate 201 of the leg assistant tool to take a rising motion.

The back board 301 of the foot auxiliary tool is directly connected with the back board 201 of the leg auxiliary tool at a certain angle, and two side boards 302 of the foot auxiliary tool are directly connected with two side boards 202 of the leg auxiliary tool.

The lateral side supporting parts 6 are arranged at the outer sides of the waist assisting tool and the leg assisting tool. The side supporting part 6 comprises a telescopic supporting rod 601, an auxiliary supporting rod 602 and a bottom anti-skid member 603. Referring to fig. 7, the telescopic supporting rod 601 may be driven to extend out manually or by a micro-motor, the auxiliary supporting rod 602 is hidden in the telescopic supporting rod 601, and the telescopic supporting rod 601 is supported obliquely when being used, so that the supporting force in the other direction is provided by the auxiliary supporting rod 602 to achieve a more stable supporting effect. Further, the bottom of the telescopic support rod 601 and the bottom of the auxiliary support rod 602 are both provided with anti-slip members 603.

The back of the waist assistive device back plate 101 is provided with an adjustable supporting frame 7. Referring to fig. 3, the adjustable support member 7 includes a bottom frame 701, two support bars 702, and a back frame. The back frame is a square frame fixed in a placement groove formed in the waist auxiliary back plate 101, two side edges of the back frame are provided with strip grooves, two side edges of the bottom frame 701 are connected with the bottom edge of the back frame through a bearing, in this embodiment, taking fig. 3 as an example, the back frame and the bottom frame 701 use a hinge 4 as a common bottom edge, and at this time, the two side edges of the bottom frame 701 are arranged on the shells of the rotary scale devices on two sides of the hinge without affecting the rotating action of the internal first connecting rod 501 and the second connecting rod 502. The top edge of the bottom frame 701 is provided with a rotating shaft 703, the bottom end of the support rod 702 is directly fixed on the rotating shaft 703, and the top end of the support rod 702 is movably embedded in the grooves on the two side edges of the back frame. The rotation shaft 703 is driven to rotate manually or by a motor. Thus, when the rotation shaft 703 rotates, the bottom end of the support rod 702 is fixed, and the top end thereof is gradually lifted and slides upward in the groove of the back frame, thereby supporting the lifting of the lumbar support. Furthermore, the supporting rod can adopt a telescopic rod, so that a better waist assisting tool supporting effect is obtained.

The

back plates

101 and 201 of the waist assistive device 1 and the leg assistive device 2 are provided with air holes 8. Meanwhile, the crotch position of the patient between the waist assisting tool 1 and the leg assisting tool 2 is hollowed, so that the daily life of the patient is facilitated.

The inner sides of the waist assistive device 1 and the leg assistive device 2 are manufactured into a curved surface shape fitting the body of the user by a 3D printing technology. Foretell rotatory scale device, side support member and back braced frame can make in advance, and the doctor carries out the 3D modeling after measuring patient's health data again, leaves certain child development's surplus, obtains final 3D model and prints the manufacturing, will change scale device, side support member and back braced frame again and install, realized like this according to different patient's assistive device individualized custom-made, wear more comfortablely, the recovered effect of postoperative is better.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, but all equivalent modifications or changes made by those skilled in the art according to the present invention should be included in the protection scope of the claims.
