Abstract

The utility model discloses a pair of pliers for fixing fractured bones used for a closed restoring and fixing method. The pliers for fixing fractured bones are composed of a pliers head, a pliers handle and a fixing device, wherein, the pliers head forms an arc circle shape and gradually thins toward the tip end, and the tail end is in a sharp shape. The pliers head and the pliers handle form an included angle. The pliers head can be separately and movably connected with the pliers handle, and the pliers head and the pliers handle can form a whole. The fixing device is used for fixing a pliers opening and keeping the clamping force for restore state of the pliers opening when the pliers opening clamps the fracture position. The pliers for fixing fractured bones solves the problem that the present closed restoring and fixing method has infirm fixation for unstable type fractured bones and easy repeated displacement of restored fractured bones.

Description

Pliers for fixing fractured bone

This utility model belongs to the fracture fixation apparatus, and what relate generally to is a kind of fracture fixation pincers.

At present, the reduction of the fracture fixation for treatment method of in the hospital fracture patient being taked has dual mode: a kind of is open reduction, internal fixation; Another kind is a closed reduction, external fixation (clamping plate, Gypsum Fibrosum and thread a needle etc.), and the former is fixed, and reduction of the fracture effect is more satisfactory, but the easy damaged tissue of its otch, and union of fracture is slow, need operation once more to take out inside-fixture; Latter's union of fracture is fast, and complication is few, but it is fixing insecure to unstable fracture, fracture displacement more easily, thus bring new wound to patient.

The purpose of this utility model promptly produces thus, the fracture fixation pincers that provide a kind of closed reduction external fixation to use.

For achieving the above object, this utility model is realized by following technical scheme, it partly is made of binding clip, pincers handle and fixture, the jaw of binding clip front end is that arc is round, gradually thin to the tip, end is a tip shape, and it is in a certain angle with the pincers handle, fixture is used for fixing jaw makes its hold reset state when the clamping fracture site chucking power, and it is arranged on the rear positions of binding clip or is arranged on the pincers handle.

This utility model is without any side effects to fracture patient, has solved in the present closed reduction fixing means unstable fracture fixing insecurely, makes the fracture problem of displacement again after resetting easily.Its use is easy and simple to handle, and reduction of the fracture effect is more satisfactory, and union of fracture is fast, and patient can do sth. in advance out-of-bed activity, and painful little, and functional rehabilitation is very fast.

This utility model has following accompanying drawing:

Accompanying drawing 1 is this utility model embodiment 1 structural representation.

Accompanying drawing 2 is embodiment 1 a clamp head part separation structure sketch map.

Accompanying drawing 3 is embodiment 1 a pincers handle structure sketch map.

Accompanying drawing 4 is this utility model embodiment 2 structural representations.

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

Embodiment 1:

As shown in Figure 1, 2, 3: this utility model partly is made of binding clip, pincers handle and fixture.The jaw of binding clip 1 front end is that arc is round, and is gradually thin to the tip, and end is a tip shape; The rear end of binding clip 1 is a pivot bush unit with pincers handle 2, and promptly insert in the pincers handle 2 rear end of binding clip 1, has " L " groove on the pincers handle 2, and after binding clip 1 inserted in the pincers handle 2, rotary clamp handle 2 tightly got final product " L " groove internal fixation of salient point 4 on pincers handle 2 that is provided with on the binding clip 1.Between the jaw of binding clip 1 front end and the pincers handle 2 certain angle is arranged, this angle is 110-120 °; Fixture partly is to be used for fixing jaw makes its hold reset state at the clamping fracture site chucking power, on the rear end of its bottom that is arranged on cardan axle 5 on the binding clip 1 and binding clip 1 and the upper position that pincers handle 2 is connected, it mainly is made of tooth plate groove 6, tooth plate 7, clamping screw 8, tooth plate groove 6 is that arc is round, the one end is fixed on one side of binding clip, another side at binding clip 1 has the notch that makes tooth plate groove 6 processes, in notch, have internal thread hole, tooth plate groove 6 is with tooth plate 7 and is threaded with internal thread hole through tooth plate groove 6 through notch on the clamping screw 8.During use, earlier with the conventional skin degerming of fracture site, shop aseptic towel, local anesthesia or nerve block anesthesia use the maneuver that resets to make the reduction of the fracture, and X line perspective is down according to fracture line
