Method for manufacturing nerve block puncture needle based on 3D printing technology and product

Abstract

The invention discloses a method for manufacturing a nerve block puncture needle based on the 3D printing technology and a product. The method includes the steps that a tissue structure at an wounded part of a patient is scanned by a scanner; 3D reconstructed models of nerves of the wounded part and adjacent structures of the wounded part are obtained; the path from a puncturing point to a target nerve is calculated, and the puncture needle required by puncture is individually and quickly printed through the 3D printing technology. According to the method for manufacturing the nerve block puncture needle based on the 3D printing technology and the product, the nerves and adjacent structures of the wounded part are scanned by the scanner, so data support is provided for the individualized customization of the puncture needle; through the 3D quick printing technology, puncture needles with different shapes, sizes, thicknesses and openings can be manufactured and molded at a time, so materials and the production cost are saved; polishing and grinding are not needed, so both time and the labor cost are saved; the accuracy of a nerve block is improved, and pains of the patient are relieved; special needs for puncturing anatomical structures of different parts are individually satisfied, blindness for clinical puncture because of anatomic variation on the patient is reduced, and medical disputes are avoided.

Description

technical field [0001] The invention relates to a preparation method of a puncture needle, in particular to a method and product for preparing a nerve block puncture needle based on three-dimensional printing technology, and belongs to the technical field of medical devices. Background technique [0002] Nerve block refers to the injection of drugs around nerve trunks, plexuses, and nodes to block their impulse conduction and anesthetize the innervated area. Nerve block only needs to be injected in one or a few places to obtain greater pain relief. Regional anesthesia effect, but there is a possibility of complications, so the operation must be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, as well as nearby blood vessels, organs and body cavities, etc., and patients often encounter anatomical variations in clinical practice, such as Normal anatomical variations or local anatomical variations caused by lesions such as tumor...

Problems solved by technology

[0003] The traditional technology of puncture needles has the following deficiencies in the production of complex three-dimensional specimens. First, the traditional technology has gone through processes such as mold making, molten slurry, injection molding, and grinding, which takes a long time and is low in efficiency. Technicians, human resources are scarce, and the production cycle is long; second, the specifications of the injection molded puncture needles are fixed, and in addition to the great variability of human anatomy, it is difficult for the puncture needles made by the fixed mold to fully conform to the anatomy of the puncture site and surrounding tissues structure, so it cannot meet the personalized puncture needs of different individuals
