CN2156817Y - Miniature automatic external recompression device for phalanges - Google Patents

Abstract

The utility model relates to an automatic miniature external pressurization device for metacarpi which is an instrument for metacarpus fracture and metacarpal arthrodesis. The utility model is characterized in that one end of each of two pressurization pull rods (5) is arranged in a sleeve tube (1), so that the pressurization pull rods are combined with a sliding rod (2) and a pressurization spring (4) into a whole; two Kirschner wires are firmly fixed by the pressurization pull rods (5), needle threading holes (6) and needle fixing screws (7), so that under the action of the pressurization spring (4), the sliding rod (2) and the pressurization pull rods (5) generate pressure, to achieve the purpose of pressurizing fracture ends. The utility model enables the fracture ends to be tightly combined together and speeds up the fracture healing, has convenient and safe operation, and can obviously shorten the treatment period and promote early recovery of finger functions.

Description

Miniature automatic external recompression device for phalanges

This utility model relates to a kind of Phalangeal fracture, the apparatus that the interphalangeal joint fusion is used--the miniature outer prelum automatically of phalanges.

At present, also do not have a kind of ideal fixing means for Phalangeal fracture, the vertical shape of many employings is worn a Kirschner wire and is fixed, and this method can not make fracture end involutory tight, and spin out the course of treatment, and postoperative influences finger function and recovers.

The purpose of this utility model is to provide a kind of Phalangeal fracture portion both sides that can make to produce a persistent impressed pressure, make fracture end in conjunction with tight, the miniature outer prelum automatically of the phalanges of accelerating bone healing, and also easy to use, safe and reliable, and can obviously shorten the course of treatment and recover finger function early.

The purpose of this utility model is achieved in that major technique is characterised in that two pressurization pull bar one ends insert in the sleeve pipe, with sliding bar and the pressing spring synthetic main body that connects together, two pressure rods are fixed Kirschner wire respectively, and are by the power that spring produces, involutory closely to reach fracture end.

Fig. 1 is the miniature outer prelum structural representation automatically of phalanges that the utility model proposes.

Further specify this utility model below in conjunction with accompanying drawing--the miniature outer prelum concrete structure automatically of phalanges;

Sleeve pipe 1, sliding bar 2, fixed screw 3, pressing spring 4, pressurization pull bar 5, the hole 6 of threading a needle, pin fixed screw 7, Kirschner wire 8.Two fixing pressurization pull bars 5, one end is inserted in the sleeve pipe 1 and sliding bar 2, pressing spring 4 integrators, by two fixing pressurization pull bars 5, two Kirschner wire 8 jails are fixed in thread a needle hole 6, pin fixed screw 7, under the effect of pressing spring 4 power, make sliding bar 2, pressurization pull bar 5 produce pressure and reach the purpose of pressurizeing, promote the fracture end combination closely to fracture end.

Claims (1)

1, a kind of by sleeve pipe (1), the miniature outer prelum automatically of the phalanges that fixed screw (3), Kirschner wire (8) are formed, pull bar (5) one ends that it is characterized in that pressurizeing are inserted in the sleeve pipe (1), sliding bar (2) is equipped with pressing spring (4), pressurization pull bar (5), the hole of threading a needle (6), pin fixed screw (7), fixes two pieces of Kirschner wires (8).
