Femoral neck Kirschner-wire positioning adjusting system

Abstract

The invention belongs to the technical field of medical instruments, and discloses a femoral neck Kirschner-wire positioning adjusting system. The distance from a second layer channel, a third layer channel and a fourth layer channel to a firs layer channel parallel to a vertical axis is 3 degrees, 6 degrees and 9 degrees from near to far wherein the second layer channel, the third layer channel and the fourth layer channel are arranged on the entrance surface of a trimmer; the trimmer is mounted on honeycomb sleeves; the honeycomb sleeves sleeve a handle of a honeycomb guider, three holes arranged in an equilateral triangle mode are formed in the upper end of the handle of the honeycomb guider, and the holes sleeve the honeycomb sleeves. A first positioning Kirschner-wire can be quickly adjusted to the ideal position by the trimmer, and the adjustment can be quantified; after the first Kirschner-wire position is satisfied, the honeycomb sleeves are installed, and it is guaranteed thatthat the three Kirschner-wires are completely parallel and are close to femoral neck cortical bone; and problems that an existing positioner has poor stability and is provided with few channels, andparallel and accurate position is difficult to quickly shoot are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a femoral neck Kirschner wire positioning adjustment system. Background technique [0002] Currently, the closest existing technology in the industry: [0003] Femoral neck fracture is a common fracture at present, and patients under the age of 65 usually undergo closed reduction and internal fixation with multiple cannulated screws. During the operation, the three cannulated screws are required to be fixed as parallel as possible and close to the cortical bone, which is conducive to the stable fixation of the fracture and the compression of the stump. The currently existing locators are generally two-channel locators, which have the following disadvantages: 1. Poor stability and few channels, so it is difficult to quickly produce parallel and ideally positioned Kirschner wires; 2. There is no positioning for the first Kirschner wire 3. If the orientation of the Kirschn...

Problems solved by technology

The currently existing locators are generally two-channel locators, which have the following disadvantages: 1. Poor stability and few channels, so it is difficult to quickly produce parallel and ideally positioned Kirschner wires; 2. There is no positioning for the first Kirschner wire Needle positioning device in vitro; 3. If the position of the positioning Kirschner wire is not ideal, there is no quantifiable micro-adjustment device

[0005] (1) The existing locator has poor stability and few channels, so it is difficult to quickly produce parallel and ideal positioning Kirschner wires

[0006] (2) There is no fine-tuning device for positioning Kirschner wires, and the fine-tuning is quantitative and accurate

[0008] It is very important to position the Kirschner wire at the bottom of the three needles. It must be located at the center of the femoral neck on the lateral view. This is the most ideal position, but it is often difficult to achieve this ideal position in clinical practice. , often a few degrees, but this is a few degrees, it is difficult to achieve in actual operation
