Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a finger flexor and extender. Background Art

[0002] The fingers cannot bend after surgery, which may be due to local soft tissue damage, adhesion and contracture. Whether the fingers can return to normal after surgery depends not only on the restoration of the hand's appearance, but also on the restoration of finger function and flexibility training.

[0003] The training methods for flexion function recovery include passive exercise, active flexion and extension exercise, and physical factor therapy. Passive exercise can be completed by massage by a doctor. Active exercise is the movement of the palm, fingers, and interphalangeal joints in all directions.

[0004] In particular, early flexion and extension exercises can prevent adhesion of joint soft tissue and promote early recovery of finger bending.

[0005] Therefore, it is necessary to design a finger flexor and extender to help patients recover finger function after finger surgery. Utility Model Content

[0038] In the following detailed description, certain exemplary embodiments of the present invention are shown and described simply by way of illustration. As will be appreciated by those skilled in the art, the described embodiments may be modified in a variety of different ways, all without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are to be regarded as illustrative in nature, rather than restrictive.

[0039] Hereinafter, a finger flexor 100 according to the present invention will be described in more detail with reference to the accompanying drawings and in combination with embodiments. The finger flexor 100 according to the present invention has a simple structure, is easy to manufacture, is economical for users, is easy to operate, and implements finger flexion and extension training in a cost-effective and easy-to-operate manner.

[0040] like Figure 1 As shown, a finger flexor 100 according to the utility model includes: a wrist sleeve 11, which is used to be fixed to the wrist; an adjustable wristband 12, which passes through the perforation on the wrist sleeve 11 and is adjustably fixed according to the size of the wrist; a fixing column 13, which is fixed to the wrist sleeve 11; a finger sleeve 15, which is used to be sleeved on the distal finger; and an elastic member 14, one end of the elastic member 14 is connected to the fixing column 13 and the other end is connected to the finger sleeve 15. The finger flexor 100 of the utility model adopts a wrist fixing method, which can be suitable for the left hand and the right hand, and does not need a single device for different hands. By using an adjustable wristband, it can be suitable for different palm sizes by adjusting the tightness.

[0041] Preferably, the wrist sleeve portion 11 includes a flange 11 a extending outwardly perpendicular to the wrist plane, and the fixing column 13 is fixed to the flange 11 a.

[0042] Preferably, the flange 11a includes five adjustment holes 11b, and the fixing column 13 is removably fixed to one of the adjustment holes 11b. By providing five adjustment holes in the upper flange of the wristband and removably fixing the fixing column to any of the adjustment holes, flexion and extension training of the corresponding five fingers can be achieved.

[0043] The fixing column 13 is in the form of a bolt rod to be threadedly connected with any adjustment hole 11b. By twisting the threaded rod, the position where the threaded rod and the adjustment hole are threadedly engaged can be adjusted, so that the length can be adjusted to suit different palm lengths.

[0044] The stiffness of the elastic member 14 can be adjusted, so that the intensity of the finger flexion and extension training can be adjusted according to the needs of different patients.

[0045] According to the first use state of the finger flexor and extender of the preferred embodiment of the utility model, the elastic member 14 is placed on the back of the hand, the wristband 11 is located on the back of the hand, the adjustable wristband 12 is located on the palm side, the flange 11a extends upward from the back of the hand, and the fixing column 13 passes through the middle adjustment hole of the five adjustment holes 11b on the flange 11a. The finger sleeve 15 is sleeved on the distal finger of the middle finger, but according to the utility model, it is not limited to this, and the finger sleeve can also be sleeved on the index finger or ring finger, or even on the thumb or little finger. Figure 1 The fixing post 13 is shown as being threadedly engaged with the adjustment hole 11b in the middle position, so as to adapt to the palm length shown in the figure. Those skilled in the art can imagine that when it is suitable for a longer palm, the fixing post 13 can be twisted so that the fixing post extends outwardly from the flange more, and vice versa. When the user performs finger flexion exercises, the user overcomes the resilience of the elastic member and performs active training.

[0046] According to the second use state of the finger flexor and extender of the preferred embodiment of the utility model, the elastic member 14 is placed on the palm side, the wrist sleeve 11 is located on the palm side, the adjustable wristband 12 is located on the back side, the flange 11a extends upward from the turned palm, and the fixed column 13 passes through the middle adjustment hole of the five adjustment holes 11b on the flange 11a. The user overcomes the resilience of the elastic member and exercises the active extension of the middle finger. When practicing other fingers besides the middle finger, the fixed column 13 can be disassembled and installed in other adjustment holes 11b, or it can be kept intact as described above. Of course, those skilled in the art can imagine that when applied to the outer fingers, it is obviously a more preferred solution to install the fixed column 13 in the same-side adjustment hole 11b.

[0047] The above describes the specific embodiments of the utility model. It should be understood that the utility model is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the utility model. Although the utility model has been described with reference to the preferred embodiments, those skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the utility model.
