Abstract

A fracture fixing device is composed of two semi-circular casings and at least three inner lining bodies, wherein the two semi-circular casings are capable of being opened and closed, and the inner lining bodies are arranged inside the casings. The ends of the two casings are movably connected while the other ends are free ends. The inner lining bodies which are placed inside the casings are fixedly connected with helical screws which are in threaded connection to the casings, the distance between each inner lining body and each casing is adjusted by screwing or unscrewing the helical screws, thereby enabling the inner lining bodies to cling to fracture limbs. Screw caps of the helical screws are located outside the casings, and the free ends of the casings are equipped with fixed locking devices. After reduction of fracture for fracture patients, the fracture fixing device is utilized to fix limbs of the patients, the fixing tightness of the fracture fixing device can be adjusted by screwing or unscrewing the helical screws, clearances among the casings and the inner lining bodies are favorable for fracture limbs to breathe freely. The fracture fixing device has the advantages of simple operation, convenient use, low cost and wide application.

Description

A kind of fracture fixation device

Technical field

This utility model relates to a kind of orthopedic medical device, is specifically related to a kind of fracture fixation device that is used for after the fracture patient knochenbruch resets.

Background technology

At present, fixing after the closed shaping of fracturing resets generally adopts clamping plate or Gypsum Fibrosum to carry out external fixation, and twines the pressurization reinforcing by binder.Because long problem of pressurization dynamics size inequality and operating time often appears in the size of doctor's dynamics and the thickness difference of patient's limbs, influences the effect of closed reduction.

The ZL03268704.4 patent disclosure a kind of fracture fixing apparatus, comprise sacculus, gasbag and clamping plate, sacculus communicates with gasbag by conduit, sacculus and conduit junction are provided with valve, the gasbag two ends are provided with button, and one side is provided with screw thread, and clamping plate are fixed by screw thread and gasbag.During use clamping plate are fixed on the appropriate location by screw thread and gasbag, after the limbs reduction of will fracturing, gasbag are stretched tight on limbs at once, and the gasbag two ends are buckled well, inflate pressurization, the valve of sacculus is screwed, reach the purpose of closed reduction by sacculus.This patent has taked sacculus to inflate the method for pressurizing valve gate control, the size of pressurization dynamics can be controlled, and reach at short notice and add press fit, can suitably adjust pressure according to patient's sensation and far-end blood fortune situation, closed reduction success rate height, it is fast to be used for the emergency case processing speed.But the fracture fixing apparatus of this patent is wrapped in gasbag on the limbs, causes the airtight airtight of limbs, makes patient very uncomfortable, and after using the long period, the situation that gasbag may leak air makes fracture fixing apparatus malfunctioning.

Summary of the invention

The purpose of this utility model provides a kind of fracture fixation device, and after to the fracture patient reduction of the fracture, fixedly patient's limbs are solid and reliable, simple to operate to utilize this fracture fixation device.

For achieving the above object, fracture fixation device of the present utility model by can separate or closed two semicircle shells and shell in three the inner lining body of being no less than that is provided with form, an end of two shells is movably connected, the other end is a free end; Inner lining body places in the shell, fixedlys connected with the spiral screw of screwed connection on shell, by screwing or unclamping the distance that the spiral screw is adjusted inner lining body and shell, makes inner lining body be adjacent to the limbs of fracture, and the nut of spiral screw is positioned at the outside of shell; Free end at shell is equipped with fixedly lock uint.

Inner lining body is made up of rigid material and elastomeric material, and rigid material is fixedly connected on the spiral screw, the flexible material of its outer wrap, and elastomeric material contacts with limbs.

One end of two shells is movably connected, and its connected mode can be that hinge connects, and also can be movably connected by flexible material, makes shell pass through flexible material expansible or closure.Described flexible material is a kind of in canvas, Corii Bovis seu Bubali, the artificial leather.

Being positioned at the free-ended fixedly lock uint of shell can be hasp, belt or rope, sealed fixedly the time when adopting belt or rope to carry out, the belt or the rope that should be no less than one mutual correspondence in the free end setting of shell are can fasten mutually when the enclosure closed.

Described inner lining body is the entire body structure, and is isometric or slightly be shorter than shell with shell, after the reduction of the fracture, opens shell, and the limbs of will fracturing are held with inner lining body, and closed shell is sealed with free end, adjusts the spiral screw, makes inner lining body and fracture limbs closely fixing.

As a kind of improvement structure of the present utility model, inner lining body is set to the branch body structure, places the both sides of shell, leaves certain cavity at the middle part.When running into comminuted fracture or wound arranged, use the fixing fracture of the fracture fixation device limbs of this structure, can fix comminuted fracture respectively or the skeleton of both sides, wound position is arranged with the inner lining body of split, and directly the injury is not fixed, help the treatment and the healing of injury.Simultaneously, place, cavity position that can also be on shell have a treatment mouthful, is changed dressings in the injury and treats by this treatment mouth.

Fracture fixation device of the present utility model is simple in structure, and is easy to use, adopts the spiral screw to connect shell and inner lining body, by screwing or unclamping the spiral screw and adjust the tightness degree that inner lining body contacts with the fracture limbs, to firmly fix the fracture limbs.Simultaneously, leave the space between shell and inner lining body, be convenient to the ventilative of limbs position of fracturing, long-time fixing, patient does not have uncomfortable sensation.

The specific embodiment

Embodiment 1

Fracture fixation device of the present utility model comprises two semicircular shells 1 as shown in Figure 1, and the one end adopts hinge 4 to connect, and is provided with the sealed hasp of mutual overlap joint 5 at free end.3 screwed connections of spiral screw are on shell 1, and nut is positioned at the outside of shell, and fixedly connected with inner lining body 2 in the inner, as Fig. 2.Forward be provided with 4 inner lining bodies of being made up of rigid material and elastomeric material 2 in shell 1, its length slightly is shorter than shell 1, and rigid material is fixedly connected on the spiral screw 3, the flexible material of its outer wrap.

During use, the fracture limbs that resetted are held with the inner lining body 2 of parcel elastomeric material, with shell 1 closure, and sealed with hasp 5, adjust spiral screw 3 and make inner lining body 2 and fracture limbs closely fixing.

Embodiment 2

Fracture fixation device of the present utility model as shown in Figure 3, comprise two semicircular shells 1, and adopt flexible materials 4 such as canvas, Corii Bovis seu Bubali, artificial leather that two shells 1 are linked together, be provided with the flexible material belt 5 of the mutual correspondence that is no less than at the free end of shell 1, can two diphase systems sealed.3 screwed connections of spiral screw are on shell 1, and nut is positioned at the outside of shell, and fixedly connected with inner lining body 2 in the inner, as Fig. 2.Forward be provided with 4 pairs of inner lining bodies of being made up of rigid material and elastomeric material 2 in shell 1, every pair of inner lining body 2 places the two ends of shell 1 respectively, leaves cavity at the middle part, and rigid material is fixedly connected on the spiral screw 3, the flexible material of its outer wrap.Simultaneously, the place, cavity position on shell 1 also has a treatment mouth 6, is used to change dressings and successive treatment.
