Humerus fracture intramedullary nail guide needle implantation template

Abstract

The invention discloses a humerus fracture intramedullary nail guide needle implantation template, and relates to the technical field of humerus operation auxiliary tools, the humerus fracture intramedullary nail guide needle implantation template comprises a fitting plate, one side of the upper end of the fitting plate is provided with a major tubercle fitting surface, and the other side of the upper end of the fitting plate is provided with a minor tubercle fitting surface; the middle of the inner side of the attaching plate is provided with an internodule groove positioning protruding block, and one end of the large nodule attaching face and one end of the small nodule attaching face are each provided with a fixing base plate. According to the humerus fracture intramedullary nail guide pin implanting template, the attaching plate is attached to the proximal humerus, the first sliding rod and the second sliding rod are used for driving the guide pin limiting column to move, and the position of a light beam seen by the laser direct illuminating lamp is changed; and the position of the fitting plate is finely adjusted, so that a light beam seen by the laser direct illuminating lamp directly faces a guide pin insertion point determined by the proximal humerus, rays emitted by the laser lamp are parallel to the humerus diaphysis, and the function of positioning the intramedullary nail guide pin implantation template is achieved.

Description

technical field [0001] The invention relates to the technical field of humeral surgery auxiliary tools, in particular to a humerus fracture intramedullary nail guide needle implantation template. Background technique [0002] The humerus is the thickest bone in the upper limb. The upper end forms the shoulder joint with the scapula, and the lower end forms the elbow joint with the radius and ulna. Fractures of the humeral shaft are often treated with implantation of intramedullary nails. The guide pin is inserted into the head end, and repeated fluoroscopy through the C-arm machine to determine whether the implanted position of the guide pin is qualified, but the steps are relatively cumbersome, and repeated fluoroscopy of the patient through the C-arm machine will cause damage to the patient's body. Currently, there is no such method The device for guiding and positioning the guide pin cannot meet the requirements of today's use, so we propose a template for implanting the ...
