Problems solved by technology

Since one end of the bridge structure is fixed on the proximal bone block of the affected side, this kind of reset device should not only use the proximal bone block of the affected side as a supporting structure, but also adjust the height, horizontal position and angle of the proximal bone block of the affected side. Perform reduction, so that the cross-bridge structure is used to fix one end of the proximal bone fragment on the affected side, which will limit the freedom of the proximal bone fragment on the affected side, affecting the accuracy of reduction and treatment effect

Embodiment 1

[0049] This embodiment provides a clavicle fracture closed reduction device, such as Figure 2-Figure 8 As shown, it includes a main frame 1, a fixing mechanism 2, an adjusting mechanism 3 and a reset mechanism 4; wherein, the fixing mechanism 2 is used to fix the proximal clavicle 61 of the healthy side, the adjusting mechanism 3 is used to fix the distal clavicle 5 of the affected side, and the reset mechanism 4. It is used to fix the fractured and detached proximal bone fragment 7 on the affected side. By changing the distance between the adjusting mechanism 3 and the fixing mechanism 2, the distal clavicle 5 on the affected side is driven to change the distance between it and the proximal clavicle 61 on the healthy side, so as to make room for the bone block 7 at the proximal end of the affected side, and at the same time achieve The effect of restoring the original position of the distal end of the clavicle 5 .

[0050] The main frame 1 is composed of a strip-shaped plat...

Embodiment 2

[0059] This embodiment provides a method for closed reduction of clavicular fractures, which adopts the closed reduction device for clavicle fractures proposed in Example 1, and implements the following steps:

[0060] Step 1: If figure 1 As shown, the first Kirschner wire 21 is implanted at the proximal end 61 of the unaffected clavicle, and the second Kirschner wire 32 is implanted at the distal end 5 of the affected clavicle.

[0061] Step 2: If figure 2 As shown, the top end of the first Kirschner wire 21 is inserted into the mounting hole 11 of the main frame 1 and fixed with the stop screw 22, the top end of the second Kirschner wire 32 is fixed on the adjustment slider 31, and the reset device is erected on the on two Kirschner wires.

[0062] Step 3: If image 3 As shown, push the height adjustment assembly 41 in the reset mechanism 4 along the chute 13 of the main frame 1, so that the reset mechanism 4 moves as a whole to above the fractured proximal bone fragment...

Abstract

The invention discloses a clavicle fracture closed reduction device and method. The device comprises a main frame, a fixing mechanism, an adjusting mechanism and a reduction mechanism, wherein the fixing mechanism and the adjusting mechanism are arranged at the two ends of the main frame respectively, and the reduction mechanism is movably arranged on the main frame; the adjusting mechanism is slidably connected with the main frame and used for fixing the far end of the clavicle of the affected side; the fixing mechanism is fixedly connected with the main frame and used for fixing the near endof the clavicle of the normal side; the adjusting mechanism slides to make the far end of the clavicle of the affected side reduced; and the reduction mechanism is used for correcting the position ofthe bone block of the near end of the affected side to make the bone block of the near end of the affected side in butt joint with the far end of the clavicle of the affected side for reduction. Thetwo ends of the reduction device are erected at the near end of the clavicle of the normal side and the far end of the clavicle of the affected side respectively, and the bone block of the near end ofthe affected side is not used as a supporting point for erecting the whole device any more. The adjusting mechanism can be used for pulling the far end of the clavicle of the affected side to move tomake the far end of the clavicle of the affected side return to the original position, the reduction mechanism can also be used for adjusting the bone block of the near end of the affected side at will to make the bone block of the near end of the affected side in butt joint with the far end of the clavicle of the affected side for reduction, and then the reduction precision and the treatment effect are improved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a clavicle fracture closed reduction device and method. Background technique [0002] Clavicle fracture is a common clinical case. After the fracture of the middle part of the clavicle, it is broken into two parts: the distal end of the clavicle and the proximal end of the affected side. Among them, the proximal end of the clavicle is the end of the clavicle facing the front of the human body, and the distal end of the clavicle is the end of the clavicle facing the rear of the human body. one end. Clinically, it is usually treated by surgically incision of the skin tissue and internal fixation with a reduction plate (hereinafter referred to as open reduction). Open reduction requires a transverse incision of about 10 cm along the entire length of the clavicle, which usually leaves a long scar after healing, which affects the appearance. In addition, the surgical area ...
