Technical Field

[0001] The utility model belongs to the field of limb fixation devices, in particular to a limb fixation device for post-severed finger replantation surgery. Background Art

[0002] Finger replantation surgery is a delicate and complex microsurgical procedure designed to reattach a severed finger and restore blood circulation and function. With the increasing incidence of accidents such as industrial production and traffic accidents, the incidence of finger amputations is also increasing. Successful finger replantation surgery not only restores finger function but also positively impacts the patient's psychological well-being and quality of life.

[0003] After finger replantation, the replanted finger is extremely fragile and requires strict protection. A fixation device can effectively restrict the movement of the affected limb, preventing damage to the replanted site from accidental collisions and traction. Proper fixation can provide a stable environment for the replanted site, promoting healing of blood vessels, nerves, and tissues. This reduces the risk of complications such as vasospasm and thrombosis caused by movement of the affected limb.

DETAILED DESCRIPTION

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example 1: As shown in the attached Figure 1 To the attached Figure 5 As shown: The utility model provides a limb fixation device after finger replantation surgery, including a support base 1, the support base 1 is sloped, and a forearm groove 2 is provided on the upper surface of the support base 1, and a palm groove 4 is provided at the end of the forearm groove 2; a fixing component is provided at the forearm groove 2 and the palm groove 4, and the support base 1 is sloped and provided with the forearm groove 2 and the palm groove 4, simulating the natural position of the human arm to provide stable support for the affected limb; the sloped design helps to elevate the affected limb, which meets the requirement of elevating the affected limb to promote blood circulation and reduce swelling after finger replantation surgery;

[0026] The fixing components include a first forearm strap 5 and a second forearm strap 6 connected to the inner wall of the forearm slot 2, a palm strap 7 connected to the palm slot 4, and a plurality of through-holes 8 provided on the side wall of the support seat 1. The first forearm strap 5 is located in the upper third of the forearm slot 2; the second forearm strap 6 is located in the lower third of the forearm slot 2. The palm slot 4 is 30 cm away from the bottom surface of the support seat 1. The first forearm strap 5 and the second forearm strap 6 are located in the upper and lower thirds of the forearm slot 2, respectively. By fixing the forearm at different positions, the stability of the forearm in the slot is ensured, and its movement is prevented from affecting the replantation site. The palm strap 7 simultaneously limits the four fingers and thumb to be fixed in the palm slot 4, ensuring the stability of the palm and preventing accidental movement of the hand.

[0027] The patient's affected limb is placed in the palm groove 4 with the palm facing upward. The palm strap 7 simultaneously limits and fixes the four fingers and thumb in the palm groove 4. The arm is set in the recessed position of the forearm groove 2. Since the palm groove 4 is 30 cm away from the bottom surface of the supporting seat 1, when the affected limb is raised, the palm is more than 20 cm above the heart level. By utilizing the gravity of the blood, the position above the heart level is conducive to venous blood return, promotes blood circulation, reduces tissue edema, and is conducive to the repair of soft tissue damage at the fracture end.

[0028] The bottom surfaces of the first forearm strap 5, the second forearm strap 6 and the palm strap 7 are all provided with a Velcro surface 20, and the side walls of the supporting seat 1 are provided with a plurality of Velcro hook surfaces 21, and the Velcro surface 20 is in contact with the Velcro hook surface 21; through the perforation 8, the length of the inserted strap can be adjusted, and the strap can be fixed by Velcro, which greatly improves the flexibility and stability of the fixation.

[0029] A fixing belt 9 is connected to the side wall of the supporting seat 1 , and a connecting ring 10 is provided on the other side wall of the supporting seat 1 .

[0030] From the above, it can be seen that after a patient has successfully undergone a finger replantation operation, he needs to use the limb fixation device for postoperative recovery. First, the support base 1 is placed in a suitable position on the bed, and the fixing belt 9 on the side wall of the support base 1 is passed under the patient, around the bed, and fixed for a circle, and connected to the connecting ring 10 on the other side wall of the support base 1 to ensure that it is stable and will not slide. The patient gently places the affected limb in the forearm groove 2 and palm groove 4 of the support base 1, with the palm facing up.

[0031] Next, the lengths of the first and second forearm straps 5 and 6 passing through the perforations 8 are adjusted according to the thickness and length of the patient's forearm, so that they can be securely fastened to the upper and lower thirds of the forearm groove 2. The palm strap 7 is then used to position and secure the patient's four fingers and thumb within the palm groove 4.

[0032] Since the palm groove 4 is 30 cm away from the bottom surface of the supporting seat 1, the patient's palm is naturally more than 20 cm above the heart level, which effectively promotes blood return.

[0033] Then, fit the Velcro fleece surface 20 on the bottom of the first forearm strap 5, the second forearm strap 6 and the palm strap 7 with the Velcro hook surface 21 at the corresponding position on the side wall of the supporting seat 1 to ensure a firm and comfortable fixation.

[0034] Example 2: On the basis of Example 1, massage elements 11 are provided at the first forearm band 5, the second forearm band 6 and the palm band 7. A limit seat 13 is provided on the bottom surface of the massage element 11. A swivel 14 is rotatably installed on the inner wall of the limit seat 13. A plurality of rotating grooves 15 are provided on the bottom surface of the swivel 14. Balls 16 are installed inside the rotating grooves 15. A micro motor 18 is installed on the upper surface of the massage element 11. A rotating shaft 17 is connected between the swivel 14 and the inner wall of the massage element 11. A reduction gear set 19 is installed between the rotating shaft 17 and the micro motor 18.

[0035] A battery module is installed inside the support base 1 , and a charging port 12 is provided on the side wall of the support base 1 .

[0036] As can be seen from the above, the micro motor 18 drives the rotating shaft 17 to rotate through the reduction gear set 19, and the rotating shaft 17 drives the rotating ring 14 to rotate.

[0037] A ball 16 is installed in the rotating groove 15 on the bottom surface of the rotating ring 14. When the rotating ring 14 rotates, the ball 16 contacts the affected limb, producing a rolling massage effect; while fixing the affected limb, it provides a certain massage function, promotes blood circulation and recovery of the affected limb, and helps to relieve the stiffness and discomfort of the affected limb during limb braking.
