Abstract

The utility model relates to an external fixation device for traction of metacarpus fracture, which is composed of a T-shaped metacarpus supporting board and an axial traction device for metacarpi, wherein, and the front end of the metacarpus supporting board is bent upwards in a 'V'-shaped to support the fingers, both sides of the metacarpus supporting board are bent downwards to support the palm, and each of both middle sides of the metacarpus supporting board is provided with a fixing strip; the axial traction device for metacarpi is composed of a traction device frame and a traction rod. The utility model has the advantages of simple structure, convenient fabrication, low cost, convenient operation and no side effect.

Description

Palmar fracture external fixation traction device

This utility model relates to a kind of fracture external fixator, particularly a kind of Phalangeal fracture external fixation traction apparatus.

The method of treatment fingers and palms bone fracture has or not the phalanges plintlet external fixation of plastotype at present, but becomes the angle to be difficult to control before the fracture, hinders osteoarthrosis to bend and stretch; The crooked moulding method of spatula has overcome fracture and has slapped into the angle, makes fracture refer to be fixed on bare-handed functional position, but extremely unstable; Maybe will fracture to hinder refers to connect same strong finger with tiing up together, referring to wound with stable support, but displacement is often arranged also, Qian Chengjiao, and rotation takes place, and strongly refers to same generation joint stiffness because of fixedly making for a long time, and often makes to fracture and be rotated into the lateral bending teratogenesis; The operation method that method or external plaster fixation add traction of threading a needle equally often causes malunion and joint stiffness to take place to fracture, does also pretty troublesomely, requires standard very high.

It is a kind of easy to use that the purpose of this utility model is to provide, simple to operate, become the angle before overcoming fracture, lateral bending overlaps and rotation displacement, the fixing finger at the flexing functional position, and to hamper only that joint capsule palm pain takes place, in whole treatment fixation procedure, but strong the finger and the equal external fixator of the treatment fingers and palms metacarpal bone folding of autonomic activities of palm wrist function.

The technical solution of the utility model be one as hand size " ⊥ " shape fingers and palms bone supporting plate, its front end is bent upwards " ∩ " shape to be finger and supports, the two ends of bottom are bent downwardly two protuberances that conform to the big hypothenar of hands of formation and are the palm fixed support, and respectively there is a fixing band both sides in the middle of it; The fingers and palms axis of bone position traction apparatus of an adjustable finger is equipped with in middle part below fingers and palms bone supporting plate, it is by a traction apparatus support, the draw bar of front end band one drag hook is formed, draw bar matches with screw on the towing bracket by the screw thread on it, this traction apparatus gives axial thrust force of hands functional position and keeps the achievement that resets, and to avoid the generation of displacements such as overlapping into angle and rotation.

Advantage of the present utility model is: 1. many usefulness at a low price, and system is with simple, and every function is various.2. simple and easy to use, patient can be with oneself, is under no restraint, and uses main points easily to grasp, and any side effect can not take place.The application time longer, can not cause unexpected injury to other finger, use relieved, reliable for effect.

Further specify present technique below in conjunction with drawings and Examples:

Accompanying drawing 1: be fingers and palms bone fracture traction external fixator structure chart.

Accompanying drawing 2: be fingers and palms bone fracture traction external fixator application drawing.

As shown in the figure, " ⊥ " shape fingers and palms bone supporting plates (1) by aluminum, its front end are bent upwards " ∩ " shape (2) to be beneficial to the hand fingers and palms to be in crooked functional position with the joint; The two ends of bottom are bent downwardly, form two protuberances (3) that conform to the big hypothenar of hands, respectively there is a fixing band (4) middle both sides, and this is fixed on the palm dorsal part, but this fixing band preferably adopts Corii Caprae seu Ovis to make and be stained with the elasto-plasticity sticking zip (9) of nylon preferably.Adjustable fingers and palms axis of bone position traction apparatus (5) is equipped with in the middle part below fingers and palms bone supporting plate, this traction apparatus is by a traction apparatus support (6), form with the draw bar (8) of front end band one drag hook (7), draw bar matches with screw on the traction apparatus support by the screw thread on it.Above-mentioned traction apparatus gives axial thrust force of hands functional position and keeps the achievement that resets, and to avoid the generation of displacements such as overlapping into angle and rotation.

Fingers and palms bone supporting plate can be an aluminum, also can be made of paper.

Claims

1, a kind of external fixator for the treatment of fingers and palms bone fracture traction, it is characterized in that it being " ⊥ " shape fingers and palms bone supporting plate as hand size, its front end is bent upwards " ∩ " shape, be and refer to support, the two ends of bottom are bent downwardly, form two protuberances that conform to the big hypothenar of hands, be hands support fixed support, respectively there is a fixing band both sides in the middle of it; Adjustable fingers and palms axis of bone position traction apparatus is equipped with in the middle part of fingers and palms bone supporting plate below, and it is by a traction apparatus support, and the draw bar that front end has a drag hook is formed, and draw bar matches with screw on the traction apparatus support by the screw thread on it.

2, fingers and palms bone fracture external fixator according to claim 1 is characterized in that described fingers and palms bone supporting plate can be an aluminum, also can be made of paper.

3, fingers and palms bone fracture external fixator according to claim 1 is characterized in that described fixing band is a Corii Caprae seu Ovis system, and is stained with the sticking zip of nylon of plastic good springiness.
