Abstract

The utility model relates to an instrument for treating mallet fingers in the medical field, in particular to an exercise brace for treating mallet fingers, comprising a near lateral support and a far lateral support which are connected through a pivot shaft. The near lateral support is provided with a connection bar, and the other end of the connection bar passes through a locating ring below the far lateral support, and is provided with a locking device. The connection bar is covered by a compression spring, and the near and the far lateral supports are respectively provided with retaining devices. Compared with the prior art, the near lateral support is connected with the far lateral support through the pivot shaft, therefore the far lateral support rotates relatively to the near lateral support, and the exercise brace can be used for actively bending near interphalangeal joints at early stages. The compression spring covering the connection bar drives the bent near interphalangeal joints to automatically return, facilitates to restore functions of the joints, controls stretching angles of the near interphalangeal joints, and protects tendon against rupture and separation.

Description

The exercise brace of treatment hammer finger function

Technical field:

The utility model relates to the apparatus of treatment hammer finger in the medical field, particularly a kind of exercise brace for the treatment of hammer finger.

Background technology:

The hammer finger postoperative needs proximal phalangeal joints is fixed in suitable flexing position, and distal interphalangeal joint is fixed in flat position or the suitable hyperextension position of stretching.Tradition expectant treatment hammer finger adopts plaster slab or refers to that holder is fixing, but how shaky, easily loosening, it is poor to cause fixed effect, and long-time fixed effect finger-joint functional rehabilitation.

The utility model content:

Goal of the invention of the present utility model is to overcome the deficiency of background technology and a kind of exercise brace that can make the treatment hammer finger function of hammer finger activity is provided.

The utility model adopts following technical scheme:

A kind of exercise brace for the treatment of hammer finger, comprise the nearside holder, the distally holder, described nearside holder is connected by jointed shaft with the distally holder, in this nearside holder connecting rod is housed, the other end of this connecting rod passes the locating ring of holder below, distally and locking device is housed, and encapsulation has the compression spring on this connecting rod, in described nearside holder and the distally holder fixture is housed respectively.

The utility model that adopts technique scheme compared with prior art, nearside holder and distally holder are hinged by jointed shaft, and the distally holder is relatively rotated with respect to the nearside holder, can do the function exercise of active flexing proximal phalangeal joints in early days; The compression spring of suit on the connecting rod, the proximal phalangeal joints that can drive flexing automatically resets, and is beneficial to the functional rehabilitation in joint, can control the angle of stretching of nearly interphalangeal joint, prevents that the tendon broken ends of fractured bone from separating.

As a kind of preferred structure of the present utility model, the described locating ring of holder below, distally that places is connected with the distally holder by pivoting support.

As a kind of preferred structure of the present utility model, described locking device is a nut.

As a kind of preferred structure of the present utility model, described fixture is thread gluing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

Below in conjunction with drawings and Examples in detail the utility model is described in detail:

A kind of exercise brace for the treatment of hammer finger, referring to accompanying drawing 1, among the figure:, nearside holder 1, jointed shaft 2, distally holder 3, the first thread gluings 4, nut 5, locating ring 6, the first pivoting supports 7, connecting rod 8,10, the second thread gluings 11 of compression spring 9, the second pivoting supports.

Nearside holder 1 and distally holder 3 connect 2 by jointed shaft and connect, connecting rod 8 is equipped with by second pivoting support 10 in the below of nearside holder 1, the other end of connecting rod 8 passes the distally and holds in the palm the locating ring 6 of 3 belows and locking device is housed, place the distally to ask the locating ring 6 of 3 belows to be connected with distally holder 3 by first pivoting support 7, there are enough gaps to make connecting rod 8 do freely-movable between locating ring 6 and the connecting rod 8, owing to adopted the connected mode of first pivoting support 7 with locating ring 6, can center on first pivoting support 7 and do relatively rotating of certain angle by drivening rod 8, the end that connecting rod 8 is equipped with locking device is provided with screw thread, locking device adopts nut 5 lockings, encapsulation has compression spring 9 on the connecting rod 8, second thread gluing 11 and first thread gluing 4 is housed as fixture in nearside holder 1 and the distally holder 3 respectively.

Nearside holder 1 fixed finger closely saves, the art joint is held in the palm in 3 fixed finger in the distally, and distal interphalangeal joint is fixed in the back of the body stretches the position, holds in the palm 3 two parts because of nearside holder 1 and distally and is connected by jointed shaft 2, distally holder 3 is relatively rotated with respect to nearside holder 1, can do the function exercise of active in early days; The compression spring 9 of suit on the connecting rod 8 can drive distally holder 3 and automatically reset, and controls the angle of nearly interphalangeal joint flexing, can rely on elasticity to stretch automatically behind the active flexion, reaches the effect of early stage exercise proximal phalangeal joints.
