AI Technical Summary

Technical Problem

Existing gold-labeled implants are prone to axial and radial displacement after implantation, affecting the accuracy of subsequent tumor radiotherapy localization and disease monitoring.

Method used

A pure gold marker implant with positioning features was designed, which uses at least two markers connected by collagen chains. The markers are equipped with fixation texture groups and various fixation structures, including comb-shaped, mushroom-shaped and multi-layered grooves, etc. It utilizes tissue compression and growth fixation, combined with barbs and limiting grooves to achieve multi-directional fixation.

Benefits of technology

It effectively avoids displacement of the gold-labeled implant, improves the clarity of imaging examinations and the accuracy of treatment, reduces tissue irritation and damage, and enhances the adhesion between the implant and the tissue.

Abstract

The present application relates to gold mark implant technology field, disclose a pure gold gold mark implant with positioning features, including at least two markers, through gold mark injector to mark injection;Connecting line is collagen chain, fixed pattern, arranged on the marker, when the marker is located in the target tissue, the target tissue extrudes the fixed pattern, so that the marker can be fixed in the target tissue;The fixed pattern includes a fixed part opened on the marker;Wherein the left view of the marker is a circular structure, wherein two mutually perpendicular axis sections in the marker divide the plan view of the marker into four regions, wherein the fixed part is located in the above region, by setting the limiting groove in the pure gold gold mark, connecting line, mushroom-shaped third fixed part and the structure of multilayer groove, further make the human tissue can enter to cooperate with the barb to realize the fixation work of gold mark implant, avoid the displacement of implant position.
