Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-4, the present utility model provides an external wrist half-support fixing brace, which includes: fixed plate 1 and fixed band 2, fixed plate 1 includes backup pad 11 and reinforcing plate 12, backup pad 11 adopts 3D net to print to make, and the surface is formed with a plurality of net holes (not shown), reinforcing plate 12 paste and locate the backup pad 11 outside is in order to strengthen backup pad 11 intensity, fixed band 2 paste is located the backup pad 11 outside is used for with fixed plate 1 is fixed in the wrist position, fixed plate 1 and fixed band 2 all adopt non-metallic material to make.

Compared with the prior art, the wrist half-support external fixing support has the advantages that the structure is simple, the fixing plate only comprises the supporting plate 11 and the reinforcing plate 12, the thickness is greatly reduced, the air permeability and the X-ray permeability can be improved while the wrist half-support external fixing support is used for fixing the wrist, the subsequent X-ray examination of a patient is facilitated, and the use experience of the patient is improved.

Specifically, the supporting plate 11 is made of PLA material, and due to the characteristics of the PLA material, the supporting plate 11 can soften and bend when heated to form a shape fitting the wrist, and when the supporting plate 11 is cooled, the supporting plate can harden, so that the supporting plate has a strong supporting property, and the wrist is fixedly supported.

Further, the edges of the support plate 11 are provided with reinforcing bars. The reinforcing strips can strengthen the edge of the supporting plate 11 and prolong the service life.

Further, a notch 111 corresponding to the metacarpophalangeal joint of the thumb is formed on the side edge of the supporting plate 11. The purpose of the notch 111 is that most of the palm's functional activities require the thumb to participate, limiting the palm's function if the thumb is secured to the other four fingers (index finger, middle finger, ring finger, and little finger); the notch 111 provides a space for thumb to move, when the support plate 11 is fixed to the wrist, the thumb can move in the notch 111, and the function of the palm is not affected as much as possible while the wrist is fixed.

Further, the supporting plate 11 has a fitting surface that fits with the palm, a first support portion 13 that can be bent and extended from between the metacarpophalangeal joint and the carpophalangeal joint of the thumb to the back of the hand is formed by extending one side of the notch 111, a second support portion 14 that can be bent and extended from the tiger mouth to the back of the hand is formed by extending the other side of the notch 111, and the wrist is clamped by the first support portion 13, the second support portion 14 and the fitting surface to fix the wrist.

Further, the attaching surface of the supporting plate 11 is rectangular, and one end extends between the metacarpal joints of the index finger, the middle finger, the ring finger and the little finger and the interphalangeal joints, so that the purpose of the arrangement is to protect the metacarpal joints of the index finger, the middle finger, the ring finger and the little finger.

Further, the other end of the supporting plate 11 extends to the forearm, so that the purpose of the arrangement is to span the carpometacarpal joint and fix the carpometacarpal joint from both ends thereof.

Further, the edge of the reinforcing plate 12 is provided with a reinforcing strip. The reinforcing strips can enhance the strength of the edges of the reinforcing plate 12 and prolong the service life.

Further, three fixing straps 2 are provided, one fixing strap 2 is disposed at one end of the supporting plate 11 near the metacarpophalangeal joints of the index finger, the middle finger, the ring finger and the little finger, and is used for fixing the index finger, the middle finger, the ring finger and the little finger with the supporting plate 11; the fixing strap 2 is arranged corresponding to the carpometacarpal joint and is used for fixing the carpometacarpal joint with the supporting plate 11; one of the fixing straps 2 is provided at the other end of the support plate 11 for fixing the forearm to the support plate 11.

When in use, the fixing plate 1 is heated to soften the fixing plate, and the fixing plate is bent into a shape matched with the hand of a patient and then is attached to the hand of the patient; the positions of the fixing plate 1 and the hand are adjusted to enable the thumb of the patient to correspond to the notch 111, one end of the supporting plate 11 is positioned between the metacarpophalangeal joints and interphalangeal joints of the index finger, the middle finger, the ring finger and the little finger, and the other end extends to the forearm; then bending the first and second support parts 13 and 14 to the back of the hand to clamp the wrist; finally, the fixing strap 2 is fixed on the fixing plate 1, so that the fixing plate 1 is fixed with the hand of the patient.

The utility model has the advantages that:
