specific Embodiment 1

[0030] Specific embodiment 1, as shown in the figure, is a preferred embodiment of the present invention, a resilient finger flexor tendon injury fixation brace, which mainly includes a fixation belt for surrounding and fixing on the finger and two for The rotation limit structure that limits the rotation angle of finger joints; the length of the fixed belt is adjustable, and the fixed belt is divided into an upper fixed belt 3 and a lower fixed belt 2, and the upper fixed belt 3 and the lower fixed belt 2 They are respectively fixed on both sides of the proximal finger joints. The upper fixing belt 3 and the lower fixing belt 2 are used to fix the rotation limiting mechanism located in the middle. There are two rotation limiting structures, which are symmetrical about the fingers. Such as Figure 3 ~ Figure 6 As shown, the rotation limiting structure mainly includes a limiting block 9 , a connecting rod 12 , an upper rod 4 , a lower rod 8 , and a limiting nut 14 . The shape ...

specific Embodiment 2

[0038] In the second specific embodiment, the fixing belt is provided with a sun-shaped buckle, and the length of the fixing belt is adjusted through the structure of the sun-shaped buckle. Similar to the length adjustment structure on the safety belt, the fixing effect is better.

Abstract

The invention provides a reboundable finger flexor tendon injury fixing brace and belongs to the technical field of medical tools. The brace mainly comprises fixing belts and a rotation limiting structure, wherein the fixing belts are used for fixing a finger; the rotation limiting structure is used for limiting rotation angles of a finger joint; the fixing belts are connected with the rotation limiting structure; the fixing belts consist of an upper fixing belt and a lower fixing belt; the upper fixing belt and the lower fixing belt are connected through the rotation limiting structure; an elastic force shrinking structure for assisting finger bending is mounted on the lower fixing belt; and the elastic force shrinking structure is connected with the upper fixing belt. Due to arrangementof the rotation limiting structure, finger bending angles can be limited, different limiting angles can be selected, and finger bending training of different degrees can be achieved; and the elastic force shrinking structure is additionally arranged, the intensity of elastic force can be adjusted by adjusting the length of an elastic force line, and furthermore, the intensity of passive bending ofthe finger can be changed.

Description

【Technical field】 [0001] The invention relates to the technical field of medical appliances, in particular to a resilient finger flexor tendon injury fixation brace. 【Background technique】 [0002] Finger flexor tendon cut injury is a common clinical disease. After surgery, the flexor position is usually fixed for three weeks, and functional exercises are required every day for three weeks to prevent tendon adhesion. The ruptured tendon cannot be actively contracted to prevent re-rupture. Activities, that is, actively straighten and passively flex the fingers. General fixation such as plaster or braces are rigid fixation, which needs to be removed every day, and the functional exercise should be conducted under the guidance of medical staff, and re-fixation after exercise is extremely inconvenient, and some patients have low cooperation and lack of understanding ability, so they cannot fully cooperate Normal functional exercise can easily cause complications of tendon ruptu...
