A combined multifunctional physiological bone compression external fixation scaffold

Abstract

The invention belongs to the technical field of medical surgical instruments, in particular to a combined multifunctional physiological bone compression external fixation bracket, which comprises a leg bracket for fixing a leg part, an ankle bracket for fixing an ankle part, a foot bracket for fixing a foot part and a longitudinal compression bracket; the leg bracket comprises a plurality of closed ring frames and a first threaded connecting rod; the ankle bracket comprises an ankle U-shaped ring frame and a second threaded connecting rod; the foot bracket comprises a foot U-shaped ring frame,a third threaded connecting rod, a transverse connecting rod, an angle adjusting device and a C-shaped frame; the upper end of the longitudinal pressurizing bracket is connected to the closed ring frame, and the bottom end of the longitudinal pressurizing bracket is rotatably connected to the top end of the C-shaped frame through a third rotating device. The angle adjusting device of the invention is used for adjusting the angle of the C-shaped frame, convenient to be installed at the diseased part of the patient, and is favorable for correcting the traction bone shape.

Description

Technical field [0001] The invention belongs to the technical field of medical surgical instruments, and specifically relates to a combined multifunctional physiological bone compression bone external fixation bracket. Background technique [0002] Skeletal deformities of the feet and legs caused by trauma, infection, congenital deformities and other reasons are common orthopedic diseases. In order to correct the bone shape and lower limb force lines, the physiological bone compression bone external fixation is usually used for orthopedic treatment. The specific methods of bone deformities caused by trauma and infection are as follows: a closed ring is placed at the proximal and lower third of the lower leg, and two half-needles are connected to the tibia; a U-shaped ring is placed parallel to the sole of the foot, and four long threads are attached. The connecting rod is connected to the proximal end, and the stent is used to provide longitudinal compression / tension; or a C-ring...

Problems solved by technology

[0003] However, for patients with congenital deformities, the shape of the patient's own bones is different from that of ordinary people, so it is usually necessary to add a C-shaped ring for fixing the foot. The C-shaped ring of the prior art is in a fixed connection relationship with other parts, and the angle Not adjustable, not conducive to installation and post-orthopedic
