Abstract

The invention provides a positioning device and method for an anterior inferior spine, and belongs to the technical field of medical instruments. The positioning device comprises a supporting frame, apositioning rod, a positioning body, a fastening assembly and a fixing assembly; the supporting frame at least comprises a first support and two second supports, the positioning rod is arranged on one second support, and the axis of the positioning rod is used for being parallel to the intersecting line of a second reference plane and a sagittal plane; the positioning body is rotationally connected with the positioning rod; the fastening assembly is arranged on the positioning rod; and the fixing assembly is connected with the positioning rod and the supporting frame. According to the device,the second supports on the supporting frame abut against anterior superior iliac spines on two sides, and the first support abuts against pubic symphysis; the positioning rod and the supporting frameare connected through the fixing assembly, so that the axis of the positioning rod is parallel to the intersecting line of the second reference plane and the sagittal plane, the positioning body rotates with the axis of the positioning rod as an axis, and the position of the anterior inferior spine is conveniently determined; and the fastening assembly on the positioning rod can fix the positioning body.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a positioning device for the anterior inferior iliac spine. Background technique [0002] The pelvis needs to be fixed after the fracture of the pelvis. The pelvis is composed of various forms of bones; The pelvis is fixed; before the screw is driven, the screw is placed in the working sleeve and enters the skin together with the working sleeve. The working sleeve can play the role of a channel for the screw to enter the ilium; the anterior superior iliac spine and anterior iliac spine The inferior spines are two protrusions at the edge of the ilium. The anterior superior iliac spine can be positioned by touching the hand. Screws can be driven into the ilium through the anterior inferior iliac spine to increase the depth of the screw into the ilium. [0003] In the prior art, the doctor drills screws to the ilium based on experience and needs to use a C-a...
