Abstract

The invention provides a preparation method of a measuring rod for measuring spacing between polyaxial pedicle screws. The measuring rod comprises a rod body and an end part, wherein the rod body comprises a mandrel, a middle layer and an identification protection layer on the outermost side from inside to outside, and an arc-shaped surface used for being attached to the outer circle surface of ascrew base of each pedicle universal screw is arranged at the end part. The preparation method comprises the following steps that step A, the mandrel is prepared from flexible metal; step B, the middle layer is arranged on the mandrel in a bonding mode, and the length used for being connected with the head is reserved for the mandrel; and step C, the middle layer is bonded and wrapped with the identification protection layer, and then the rod body and the end part are bonded and fixed to finish the preparation of the measuring rod. The measuring rod prepared with the preparation method of themeasuring rod for measuring the spacing between the polyaxial pedicle screws is convenient to operate, and the treatment efficiency and effect in the spinal internal fixation implementation process are greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a method for preparing a measuring rod used for measuring the distance between pedicle universal screws. Background technique [0002] The combined use of two kinds of spinal internal fixation devices, pedicle universal screw and connecting rod, is a commonly used internal fixation method in spinal internal fixation. Connecting rods are usually made of hard, high-strength metals such as titanium alloys, and have fixed specifications (for example, the commercially available Meizhou Fuchang Medical Instrument Co., Ltd. has a diameter of 5.5 mm and a length of 50, 60 to 100, 140 mm). length models of connecting rod products), [0003] When implementing spinal internal fixation, after the pedicle universal screw is fixed on the patient's spine, according to the specific patient's condition, it is necessary to determine the length of the connecting rod that connects multiple ped...
