Preparation device of antibacterial coating of implantable medical instrument

Abstract

The invention discloses a preparation device of an antibacterial coating of an implantable medical instrument. The instrument comprises anti-skid supporting legs, a ball mill, a mounting plate, a movable rotating rod, a temporary storage box and a fixed rotating rod, anti-skid supporting legs are welded on the lower surface of the mounting plate, a slide way is formed in one side of the inner partof the mounting plate, and a slide block is arranged in the slide way in a sliding mode; a movable rotating rod is arranged at the upper end of the sliding block, and a fixed rotating rod is arrangedon one side, deviating from the slide way, of the upper end of the mounting plate; the top of the fixed rotating rod is provided with a supporting plate, spherical bearings are installed at the top ends of the movable rotating rod and the fixed rotating rod, the ball mill is inserted into the spherical bearings, and a feeding device is arranged at the upper end of one side, close to the fixed rotating rod, of the ball mill; and a feeding hole is formed in the middle position of the feeding device, and a sealing plate is arranged at the upper end of the feeding opening in a sliding mode. According to the preparation device, the feeding can be conveniently carried out, and the surface of the raw material can be polished to be smooth through the ball mill, so that the coating effect is better.

Description

technical field [0001] The invention relates to the technical field of antibacterial coating preparation devices, in particular to an antibacterial coating preparation device for implantable medical devices. Background technique [0002] With the aging of modern society and the accelerated pace of life, the number of patients with orthopedic injuries has increased sharply. Bacterial infection of orthopedic implants and internal fixation devices can cause catastrophic complications, which is a very difficult problem in the current orthopedic treatment and rehabilitation. Not only It has brought great pain to patients, wasted a lot of medical and health resources, and caused huge economic losses to the country and individuals. Therefore, a technology is now needed to coat the implanted bone with an antibacterial coating. Now What is needed is an apparatus that enables the preparation of antimicrobial coatings. Contents of the invention [0003] The purpose of the present in...
