A kind of medical distal radius anatomical bracket splint and preparation method thereof
An anatomical technique for the distal end of the radius, applied in fractures, medical science, and additive processing, can solve problems such as compression of veins, inconsistent length of splints, and easy compression of bony protrusions, so as to promote swelling and subsidence, and benefit veins of affected limbs. And lymphatic return, promote healing effect

Embodiment
[0024] see Figure 1-3 , a medical distal radius anatomical bracket splint, comprising a palm splint 1 and a forearm splint 2 for fixing the forearm, the shape of the inner wall of the forearm splint 2 is consistent with the shape of the forearm; The two edges of the telescopic port 3 are provided with Velcro 4 that can fix the position of the telescopic port 3; the surface of the forearm splint 2 and the palm jacket 1 are provided with a connecting seat 5, and the forearm splint 2 and the palm jacket 1 pass through The support rod 6 fixed on the connection seat 5 is connected and fixed; the palm jacket 1 is provided with an opening 7 for extending the thumb.
[0025] In this embodiment, the palm clamp 1 is set outside the palm, and the position of the palm clamp 1 can be fixed by extending the thumb; The inner wall fits seamlessly with the forearm, so that the restored fracture site can satisfy anatomical reduction or approximate anatomical reduction. At the same time, by c...
Embodiment 2
[0029] A kind of preparation method of medical distal radius anatomical bracket splint, comprises the steps:
[0030] Step 1: Establish a three-dimensional coordinate system, determine the position of the positioning axis in the coordinate system, move the arm close to the positioning axis, use ultrasonic waves to scan the palm and forearm 360°, measure the vertical distance between the bone and skin surface and the positioning axis, According to the determined positions of the bone and skin relative to the positioning axis, a three-dimensional full-scale model of the palm and forearm is established in the three-dimensional coordinate system, and a three-dimensional full-scale model of the palm jacket 1 and the forearm splint 2 that can fit the palm and the forearm is generated;
[0031] Step 2: according to the degree of the patient's fracture and the location of the fracture, a model of the connecting seat 5 and a model of the support rod 6 are set on the three-dimensional fu...
