AI Technical Summary

Technical Problem

Existing bone filling devices cannot achieve targeted injection of bone fillers, cannot meet the treatment needs of partially collapsed vertebrae, and pose a risk of bone filler leakage.

Method used

A bone filler directional filling component was designed, comprising an injector and a mesh bag. An injection window is provided on the mesh bag, and a mark is provided on the outer end of the injector to indicate the orientation of the injection window. The injection direction is controlled by a handle connected by a threaded structure to achieve directional filling of bone filler. The mesh bag is fixed by a bending part to reduce the risk of leakage.

Benefits of technology

It enables targeted filling of bone fillers, meets the treatment needs of partially collapsed vertebrae, reduces the risk of leakage, and improves treatment outcomes.

Abstract

The present application provides a bone filler directional filling assembly and relates to the technical field of medical devices. The bone filler directional filling assembly comprises an injector and a mesh bag disposed at an inner end of the injector. The mesh bag is provided with an injection window, and when a bone filler is injected, the bone filler is dispersed outwards by means of the injection window. An outer end portion of the injector is provided with an identifier for indicating the orientation of the injection window. During operation, the identifier is located outside a human body, and an operator can determine the orientation of the injection window on the mesh bag by means of the identifier. The bone filler directional filling assembly provided by the present application can achieve directional filling of a bone filler, thereby meeting the medical needs of patients with partial collapse of the vertebral body.
