Abstract
The invention discloses a multi-angle fixed length-adjustable wartime simple unilateral external fixation frame. The frame comprises intra-bone implantation half needles, an extra-bone external fixation frame rod and a traction extension screw rod, wherein the two ends of the traction extension screw rod are in threaded connection with the extra-bone external fixation frame rod; and a long-strip-shaped hole is formed in the external fixation frame rod in the length direction, the intra-bone implantation half needles are connected with the extra-bone external fixation frame rod at the long-strip-shaped hole, the included angle alpha between at least two intra-bone implantation half needles ranges from 0 degree to 30 degrees, and the included angle is located in the transverse section of the extra-bone external fixation frame rod. The overall length of the length-adjustable multi-angle fixed wartime simple unilateral external fixation frame is adjustable, and the intra-bone implantation half needles can be used for battlefield first aid; operation is easy, carrying is convenient, wound care is facilitated, shortening and angulation malformation of an affected limb can be reduced as much as possible in the early stage of injury, and secondary injury of the broken bone end to peripheral vascular nerves in the carrying process is reduced.
Description
technical field [0001] The invention belongs to the field of first-aid external fixators for open fractures on the front line of the battlefield, and in particular relates to a wartime simple unilateral external fixator with multi-angle fixation and adjustable length. Background technique [0002] Due to the emergence and use of weapons of mass destruction in modern warfare, battlefield injuries are characterized by high energy and high violence. The incidence of open limb fractures due to high-energy injuries is gradually increasing, and the safe, effective, easy-to-operate, and portable battlefield first-aid external fixator has become a research hotspot and difficulty. The splints, plasters or braces used in the traditional treatment of open fractures on the battlefield have the following problems: 1) The splints, plasters or braces are used for fixation, the fixation effect is poor, and the bone ends can still move during the transfer of the wounded, which increases the ...
