Abstract

Disclosed is a finger fracture reduction apparatus. The finger fracture reduction apparatus is characterized by comprising a pair of forceps with a locating structure, two splints which are arranged on a tong head part and are driven by the tong heads on two side of the forceps, supports connected to the splints, sleeves which are arranged on the supports and are diagonally opposite to a center line between the two splints, guide sleeves which are arranged in the sleeves and are used for guiding a kirschner wire, wherein narrow slits are arranged in the inner side of the sleeves and the width of the slits is larger than the diameter of the kirschner wire and smaller than the external diameter of the guide sleeves. Compared with the prior art, the finger fracture reduction apparatus has the advantages that the kirschner wire can be accurately infiltrated into the fracture reduction part so as to fix the fracture part after the reduction is carried out.

Description

A kind of care of fractured fingers reduction instrument

Technical field：

The present invention relates to a kind of medicine equipment.

Background technology：

Care of fractured fingers reset or articulations digitorum manus fracture replacement and fixation are carried out using Kirschner wire, generally require to intersect insertion Kirschner wire, If clinically such operation is just difficult to hold against staff, generally requires repeatedly to squeeze into, could effectively search out conjunction Suitable squeezes into a little, so, not only easily causes additional injury, and, so that Kirschner wire is loosened, lead to fixation insecure.

Content of the invention：

The goal of the invention of the present invention is to provide a kind of Kirschner wire disposably just can squeeze at the reduction of the fracture exactly, after resetting The fixing care of fractured fingers reduction instrument of fracture.

The present invention is achieved in that including the pliers with location structure, is arranged on being clamped by both sides at pliers binding clip Head two clamping plate driving respectively, the support being connected on clamping plate, it is arranged on oblique on support against the center line between two clamping plate Sleeve, the fairlead for guiding Kirschner wire being arranged in sleeve, the inner side of sleeve is provided with slit, and the width of slit is more than The diameter of Kirschner wire and be less than the external diameter of fairlead.

During use, after resetting at care of fractured fingers, first with the pliers with clamping plate, the fracture after resetting is fixed and passed through The location structure of pliers makes pliers maintain clamp position, and makes the position of fairlead and point to positioned at accurate position, Ran Houtong Cross fairlead and insert Kirschner wire toward at the reduction of the fracture, fix at the reduction of the fracture, after insertion Kirschner wire, be first directed to set from sleeve Interior taking-up, then unclamps location structure, unclamps pliers, so that pliers is opened, and Kirschner wire removes from the slit of sleeve medial surface, this Sample, it is possible to take off pliers, so, just completes the fixation resetting at care of fractured fingers.

Here, support includes being fixed on guide rail outside clamping plate, the moving member along guide rail movement, and sleeve is arranged on moving member On, it is provided with fixed structure moving member being fixed on guide rail between guide rail and moving member.During use, existed by arranging moving member Position on guide rail is adjusting the direction of Kirschner wire inserting needle, and so that moving member is fixed on guide rail by fixed structure.

Guide rail is a shaft, and moving member is to wear the block being connected on shaft, and fixed structure is to pierce into block And the screw rod of the guide rail that goes directly.

It is provided with the angular adjustment fixed structure for regulating sleeve angle of inclination, angular adjustment fixed structure includes connecting Bar on sleeve, standing screw, the bar on sleeve turns through moving member, and standing screw spins on moving member and vertically straight Reach on bar.

During use, by rotating moving member（Block）On screw rod moving member is fixed on guide rail（Shaft）On, from And moving member is fixed, after the angle adjustment of sleeve is good, be tightened screw rod, and sleeve is fixed.

The medial surface of clamping plate is provided with some plush coppers, so, even if it is not very that clamping plate medial surface and finger knochenbruch are combined place Match, the finger knochenbruch place of being combined is fixed by the plush copper that also can be combined place by easily abutting against finger knochenbruch.

Compared with the prior art the present invention, due to guiding the insertion of Kirschner wire using fairlead, therefore, has Kirschner wire energy Squeeze into exactly at the reduction of the fracture, by advantage fixing for the fracture after resetting.

Fig. 4 is Fig. 1 D to schematic diagram.

Specific embodiment：

In conjunction with drawings and Examples, the present invention is described in further detail：

As shown in figure 1, the present invention is included with location structure 1（It is arranged on the clasp on pliers two handle）Pliers 2, be arranged on Two clamping plate 4 being driven respectively by both sides binding clip 3 at pliers 2 binding clip 3（The medial surface of clamping plate 4 is in match with facies laterales digitorum manus Cambered surface）, be connected on clamping plate 4 support E, be arranged on oblique on the support E sleeve F against the center line between two clamping plate 4, setting The fairlead 7 for guiding Kirschner wire B in sleeve F, as shown in figure 3, the inner side of sleeve F is provided with slit F1, slit F1 Width be more than the diameter of Kirschner wire B and be less than the external diameter of fairlead 7.

Support E include being fixed on clamping plate 4 outside guide rail 5, along guide rail 5 movement moving member 6, sleeve F is arranged on movement On part 6, lead and between 5 rails and moving member 6, be provided with the fixed structure 8 moving member 6 being fixed on guide rail 5.

Guide rail 5 is a L-shaped shaft, and moving member 6 is to wear the block being connected on shaft 5, and fixed structure is one Pierce into block 6 screw rod of the montant 5a of shaft 5 of L-shaped of vertically going directly.

As shown in Figure 1, 2, it is provided with the angular adjustment fixed structure 9 for regulating sleeve F angle of inclination, angular adjustment is solid Fixed structure 9 includes bar 10, the standing screw 11 being connected on sleeve F, and the bar 10 on sleeve F turns through moving member 6, fixing spiral shell Bar 11 spins on moving member 6 and vertically goes directly on bar 10.

The cross bar 5b of the shaft 5 of L-shaped is bent downwardly, and so, moving member 6 is at low level, so that fairlead 7 faces The middle part of A at care of fractured fingers reset, to ensure that Kirschner wire fixes at finger knochenbruch reset.

As shown in figure 4, the medial surface of clamping plate 4 is provided with some plush coppers 12.

When using as shown in Figure 2, after at care of fractured fingers, A resets, first with the pliers 2 with clamping plate 4 by the fracture after resetting Place A fix and pass through pliers 2 location structure 1 make pliers 2 maintain clamp position, then along guide rail 5 move up and down moving member 6 and Rotational sleeve F, makes the position of fairlead 7 and points to positioned at accurate position, by fixed structure（Screw rod）8 and angular adjustment solid Fixed structure 9（Standing screw 11 on the bar 10 of sleeve F）Sleeve F is fixed, then passes through the past fracture of fairlead 7 in sleeve F At reset, A insertion Kirschner wire B, A at the reduction of the fracture is fixed, and takes out fairlead 7 from Kirschner wire B afterbody, unclamps location structure 1, Pliers 2 is made to open, Kirschner wire B removes from the slit F1 of sleeve F medial surface, takes off pliers 2, so, just completes care of fractured fingers The fixation that place resets.
