Abstract

The present invention discloses an in-vitro positioner for a percutaneous nail and belongs to the technical field of medical devices. The in-vitro positioner for the percutaneous nail comprises a positioning base, first guide rails are symmetrically arranged on two sides of the positioning base, first installation sliding blocks are arranged on the first guide rails in a sliding mode, second guiderails perpendicular to the first guide rails are arranged on the first installation sliding blocks, and hollow guide rods are arranged on the second guide rails in a sliding mode. The two guide railsperpendicular to each other are arranged, positioning of the hollow guide rods at any position of a plane can be achieved, and then percutaneous nail leading-in is conducted at a corresponding position.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a percutaneous nail external locator. Background technique [0002] Minimally invasive spinal surgery is favored by more and more clinicians because of its advantages such as small trauma, small incision, and rapid recovery of patients in the later stage. However, because minimally invasive surgery is not an open surgery, it puts forward very high requirements on surgical positioning and approach, so ordinary doctors dare not try it. Even experienced doctors have to repeat the positioning many times during the surgical approach. Only by taking a film can the positioning needle be inserted into the pedicle more accurately. The minimally invasive implantation of percutaneous nails in the spine requires repeated confirmation by X-rays before the skin entry position can be found. Because of the distance between the skin surface and the cone, it is very difficult to insert t...
