Embodiment 1

[0036] Such as Figure 1-6 shown

[0037] A combined elastic external fixation bracket for extremity fractures, comprising two reset brackets 1, several drawbars 2 and several fixation components 3, the reset brackets 1 are connected through the drawbars 2, and the fixation components 3 can be fixed on the reset bracket 1 Adjust angle and lock;

[0038] The main body of described resetting support 1 is semicircle support 101, and the open end of semicircle support 101 axially offers two symmetrical through holes 102, offers some widths and through 102 holes identical in diameter on semicircle support 101. Through the arc groove 103;

[0039]The traction rod 2 includes connecting rods 201 at both ends and a functional rod 202 in the middle. The end of the connecting rod 201 is a threaded rod 203 with a tapered diameter, the diameter of which is the same as the through hole 102 of the reset bracket 1, and a matching locking nut is provided 204, the connecting rods 201 are con...

Embodiment 2

[0048] A method for using a combined elastic external fixation bracket for limb fractures;

[0049] The method of using the combined elastic external fixation bracket for extremities fractures is as follows: select a suitable position and approach at both ends of the cross-joint fixation joint, fix the reduction bracket 1 through the fixation component 3, and then select a suitable size according to the needs. The function bar 202 assembles the draw bar 2, and connects and fixes the reset support 1 through the draw bar 2.

[0050] The resetting bracket 1 passes through the arc groove 103 through the functional bolt 301 of the fixing assembly 3, and the head end of the Kirschner wire 304 points to the center end of the semicircular arc bracket 101 and penetrates from the semicircular arc groove 103, and the gram is adjusted by rotating the functional bolt 301. The Kirschner wire 304 is driven into the Kirschner wire 304 at an angle, and then locked by the functional nut 303 and...

Embodiment 3

[0055] The application of a combined elastic external fixation bracket for limb fractures in the fixation of limb fractures across wrist joints, ankle joints and knee joints.

[0056] In the fixation of limb fractures, cross-joint fixation is often required. When using the combined elastic external fixation bracket of the present invention to fix wrist joints, ankle joints, and knee joints, the specific operations are as follows:

[0057] First of all, the approach of cross-articular external fixation at both ends of the joint is selected through imaging equipment. The specific operation is to insert Kirschner wires at both ends of the joint under the imaging equipment as needed. In principle, at least two Kirschner wires are placed at one end. Needle;

[0058] When the wrist joint is fixed across joints, select both ends of the wrist joint to insert Kirschner wires;

[0059] When the ankle joint is fixed across the joint, select both ends of the ankle joint to insert Kirschn...

Abstract

The invention discloses a combined elastic external fixation bracket for limb fracture, and relates to the technical field of fracture external fixation. The combined elastic external fixation bracketcomprises two reset brackets, a plurality of drawbars and a plurality of fixing assemblies. The reset brackets are connected by the drawbars, the fixing assemblies are fixed on the reset brackets, the angle can be adjuted, and locking can be achieved. The reset brackets are provided with through holes and through arc grooves. Each drawbar includes connecting bars at both ends and an intermediatefunction bar, and the function bar is a resilient element bar or a non-elastic element bar. The nut end of a function bolt of each fixing assembly is provided with a semicircular groove for containinga kirschner wire, and the function bolt penetrates the corresponding through arc groove of a semicircular bracket to be locked by a function nut. The bracket can achieve the slight joint activity after cross-joint fixing for the limb fracture, the joints fixed and not fixed can be moved actively to facilitate functional exercise and rehabilitation of patients, and the bracket is suitable for fracture cross-joint fixing popularization and application.

Description

technical field [0001] The invention relates to the technical field of fracture external fixators, in particular to a combined elastic external fixator for limb fractures. Background technique [0002] Fracture refers to a complete or partial break in the continuity of the bone structure; it is more common in children and the elderly, and sometimes occurs in young and middle-aged people; patients often have a fracture at one site, and a few have multiple fractures; there are three main reasons for fractures : Direct violence: Violence directly acts on a certain part of the bone, resulting in a fracture of the part, resulting in fracture of the injured part, often accompanied by soft tissue damage of varying degrees, such as a wheel hitting the calf, and tibia and fibula shaft fractures at the impact site; indirect violence: Indirect violence Fractures occur at a distance through longitudinal conduction, leverage or torsion. For example, when the foot falls from a high place ...
