An auxiliary positioning and aiming device for limb bone traction

Abstract

The invention discloses a limb bone traction auxiliary positioning and aiming device, which comprises a base (1), the shape of the base is a rectangular block, and two horizontal dovetail grooves (2) arranged along the length direction and parallel to each other are arranged on the top surface of the base; The horizontal dovetail groove is slidably connected with the horizontal dovetail key (4) at the bottom of the two horizontal sliders (3), and the two horizontal sliders are arranged symmetrically; a vertical dovetail groove (5) is arranged on the outside of the two symmetrically arranged horizontal sliders. The vertical dovetail groove on the outside of the slider is slidingly connected to the vertical dovetail key (7) on one side of the vertical slider (6); the upper side of the vertical slider is provided with a through hole (8) parallel to the base, and a sleeve is arranged in the through hole (9), a traction needle (12) is arranged in the casing; a threaded hole (10) is arranged on the top of the vertical slider, and the threaded hole is perpendicular to and intersects with the through hole; a screw is arranged in the threaded hole. The invention has the advantages of simple structure and accurate positioning, which is beneficial to the normal reduction of the fracture site. Those skilled in the art can complete the operation.

Description

technical field [0001] The invention relates to a limb bone traction auxiliary positioning and aiming device, which belongs to the technical field of medical auxiliary devices. Background technique [0002] Bone traction is widely used in clinical orthopedics and trauma surgery, and it is convenient to use. Bone traction uses the suspension weight as the traction force and the body weight as the counter traction force through the traction device to overcome the contraction force of the muscles, restore fractures and dislocations, and prevent and correct soft tissues. Contractures, and a treatment for preoperative loosening of tissues or postoperative immobilization in certain diseases. The limb bone traction system makes the traction directly act on the bone through the Kirschner wire (bone round needle) penetrating into the bone, and plays the role of reset, fixation and rest. [0003] However, at present, there are the following defects in the use of Kirschner wires (bone...
