Abstract

The utility model relates to a micro-invasive reduction forceps for bone fracture which is characterized in that: the front end of the upper forceps 1 is composed of three stages of connecting rods hinged orderly, wherein the front connecting rod is hinged with the front end of the lower forceps 2 and the three stages of connecting rods form a ladder structure together with the lower forceps 2 under the upper forceps; the handle of the upper forceps 1 is fixed on the handle of the lower forceps 2 through a locking mechanism. The utility model has perfect micro-invasive reduction effect on the bone fracture, low cost, good oriented effect, easy operation and little damage on the human body and can be used repeatedly.

Description

Fracture Wicresoft reduction forceps

One, technical field:

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of fracture Wicresoft reduction forceps.

Two, background technology:

At present, in clinical reduction of the fracture operation, the fracture operation treatment at first will be adopted reset process, and in the process that adopts reset process, three kinds of modes are arranged usually, and a kind of is to lever up with the position of pin with fracture by puncture, and fracture portions is slowly healed, this mode reset effect is poor, and especially reset effect is poorer when cone compression fracture and articular surface collapsed fracture; What another kind adopted is to cut in fracture portions to reset, this treatment is big to the human body wound, the sacculus that the third mode adopts resets, by fracture portions being resetted to inflated, the sacculus of this mode is disposable, and costs an arm and a leg, and can squeezing action be arranged to contiguous intact bone trabecula in to the process of the reduction of the fracture, increase secondary damage, be unfavorable for union of fracture.

Three, summary of the invention:

The purpose of this utility model provides a kind of fracture Wicresoft reduction forceps, solve existing reduction of the fracture apparatus reset effect poor, cost an arm and a leg and the problem big to injury of human.

Concrete scheme of the present utility model is: a kind of fracture Wicresoft reduction forceps, the horizontal end of last pincers is hinged on down on the pincers by hinge, in the sliding infra pincers of the middle front part cover of last pincers, it is characterized in that: A, the front end of going up pincers constitute by three sections connecting rods are hinged successively, wherein preceding end link is hinged with the front end of following pincers, the following pincers formation trapezium structure of three sections connecting rods and lower end; B, the handle that upward clamps are fixed on down on the handle of pincers by retaining mechanism.

The front end of going up pincers in this programme constitutes by three sections connecting rods are hinged successively, preceding end link is hinged with the front end that clamps down, when last pincers are mobile backward, along with last pincers move, three sections connecting rods also upwards arch upward thereupon, when proceeding to correct position, can fix last pincers, and then fracture portions is resetted by retaining mechanism.

Adopt the beneficial effect of such scheme to be: fracture Wicresoft better reduction, price is low, and directional effect is good, and is reusable, easy to operate, little to injury of human.

Four, description of drawings:

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

Five, the specific embodiment:

As can be seen from Figure 1: this utility model mainly by last pincers 1, clamp 2 down, hinge 3, sliding bar 4 constitute, the horizontal end of wherein going up pincers 1 is hinged on down on the pincers 2 by hinge 3, in the sliding infra pincers 2 of the middle front part cover of last pincers 1, it is characterized in that: A, on clamp 1 front end and constitute by three sections connecting rods are hinged successively, wherein preceding end link is hinged with the front end of following pincers 2, the following pincers 2 formation trapezium structures of three sections connecting rods and lower end; B, on clamp 1 handle and be fixed on down on the handle of pincers 2 by retaining mechanism.Three sections mutual angles of connecting rod are greater than 135 °.

From Fig. 1 also as can be known: the arranged outside at pincers 1 handle has crooked sliding bar 4, on the sliding bar 4 groove is arranged, and the retaining mechanism of following pincers 2 slides along groove.

From Fig. 1 also as can be known: retaining mechanism is the bolt and nut syndeton.

When this utility model need use, front end of the present utility model is extend into the fracture place that need reset by puncture, along with moving the handle of going up pincers 1 backward, three sections connecting rods of last pincers 1 also can upwards arch upward thereupon, because three sections mutual angles of connecting rod are greater than 135 °, three sections connecting rods are trapezoidal state all the time when upwards arching upward, have like this to finish the resetting of fracture, and can lock last pincers 1 by clamping 2 bolt and nut retaining mechanism down in the reseting procedure; After finishing when resetting, the bolt and nut retaining mechanism is unclamped, move forward the handle of pincers 1, three sections connecting rods that clamp 1 front end are the level of state withdraw from along puncture channel.

Claims

1, a kind of fracture Wicresoft reduction forceps, the horizontal end of last pincers (1) is hinged on down on the pincers (2) by hinge (3), in the middle front part sliding infra pincers of cover (2) of last pincers (1), it is characterized in that: A, the front end of going up pincers (1) constitute by three sections connecting rods are hinged successively, wherein preceding end link is hinged with the front end of following pincers (2), following pincers (2) the formation trapezium structure of three sections connecting rods and lower end; The handle of B, last pincers (1) is fixed on down on the handle of pincers (2) by retaining mechanism.

2, fracture according to claim 1 Wicresoft reduction forceps is characterized in that: the arranged outside at last pincers (1) handle has crooked sliding bar (4), and sliding bar has groove on (4), and the following retaining mechanism that clamps (2) slides along groove.
