Abstract

The utility model relates to an external fixer with a single side for a department of orthopaedics. The utility model comprises a main frame, a lateral compression rod, fixing needles and a T-shaped sleeve barrel, wherein, the main frame is divided into three sections, the middle section is a telescopic adjusting section, and other two sections are installing sections for the fixing needles. When used, the lateral compression rod is connected to the telescopic adjusting section, and the fixing needles are fixed by the installing sections for the fixing needles on the main frame after the fixing needles penetrate through bones. The connecting ends of the fixing needles and the T-shaped sleeve barrel are provided with square invagination planes. Through holes in which pin nails are arranged on the side walls of the hollow parts of the connecting ends of the T-shaped barrel and the fixing needles. The external fixer with a single side can achieve reposition and fixation for fractures through external acting force under the perspective assistance of X rays because of the firm connection between the T-shaped sleeve barrel and the fixing needles. After the utility model is used, conglutinating velocity of the fractures obviously becomes faster, patient's pain is simultaneously lightened, and scars after conglutination are small. In addition, operation cost is greatly reduced.

Description

Axial external fixation
Technical field
This utility model relates to a kind of surgical medical equipment, relates in particular to a kind of orthopaedics external fixer.
Background technology
At present the clinical orthopaedics doctor is the most frequently used when long bone shaft fracture is selected external fixator for use is axial external fixation, it have safety firmly, simple operation and other advantages.It is made of body frame, side constrictor, locking pin, T-shape sleeve.Body frame comprises three parts, and three parts connect by universal joint, and the body frame middle part is the telescopic adjustment section, and the body frame both sides are the locking pin construction section.The side constrictor is installed on the telescopic adjustment section of body frame when using, in order to stretching of quantitative this section of adjusting.Locking pin is positioned by body frame after screwing in the bone.The screw-in of locking pin is finished by the T-shape sleeve, and their connection is a kind of to be semicircle bayonet type, and another kind is T-shape sleeve and locking pin interference fit, with pin both is fixed together.But thereby these two kinds of connected modes have determined can't firmly be connected between T-shape sleeve and the locking pin and have produced multi-direction active force; regular meeting occurs breaking away from or lax situation in the time of in the use; therefore be trapped in before the installation at first must open surgery for external fixation; with the reduction of the fracture, could under the prerequisite of utilizing the apparatus stable fracturing end, wear locking pin, external fixer is installed.Do not only time and effort consuming like this, increase the weight of financial burden, and certainly exist wound in open surgery, the cutting of operative incision, soft tissue, periosteum, separation all can destroy the blood fortune of fracture end, influence the time and the quality of union of fracture, also have the probability of wound infection simultaneously.
Summary of the invention
The purpose of this utility model provides the axial external fixation that a kind of locking pin and T-shape sleeve are connected firmly.
The technical scheme of taking is as follows for achieving the above object:
A kind of orthopaedics axial external fixation, it comprises body frame, the side constrictor, locking pin and T-shape sleeve constitute, body frame is divided into three sections, three intersegmentally connect by universal joint, the stage casing is the telescopic adjustment section, other two sections is the locking pin construction section, the side constrictor is connected on the telescopic adjustment section when using, locking pin is fixed by the locking pin construction section on the body frame after penetrating skeleton, be characterized in: locking pin and the design of T-shape sleeve link have the square plane of caving in, have through hole on the sidewall of T-shape sleeve and locking pin link hollow space, be equipped with pin in the through hole.Spinning in and out by pin realize fixedlying connected of T-shape sleeve and locking pin.
Adopt the axial external fixation of such scheme, because firm connection the between T-shape sleeve and the locking pin, just can reach resetting of fracture by interaction in vitro power down and fix in that radioscopy is auxiliary.Make the fracture that is fit to the installation external fixer become closed reduction, fixing by open surgery, thereby reduced the wound to local soft tissue, periosteum, little to the influence of fracture site blood circulation, the healing rate of fracture is obviously accelerated, alleviated patient's misery simultaneously, and more the back cicatrix is little.Also greatly reduce surgery cost in addition.
The utility model is described in further detail below in conjunction with drawings and Examples.
