Problems solved by technology

Aseptic loosening of the prosthesis refers to the aseptic inflammation induced by various micron-sized particles (including metal particles, polyethylene particles, ceramic particles, etc.) that appear around the prosthesis after artificial joint replacement. , and then induce periprosthetic osteolysis leading to prosthesis loosening, which is the main long-term complication after artificial joint replacement, seriously affecting the service life of artificial joints and the long-term quality of life of patients, and the existing aseptic loosening of prosthesis Patients have to undergo revision surgery to regain joint motion, but such treatments are expensive and difficult to perform

Embodiment Construction

[0016] The specific implementation of a device for releasing foreign body particles in animal bones will be described in detail below with reference to the drawings and specific examples.

[0017] Such as Figures 1 to 3 As shown, a device for releasing foreign body particles in animal bones includes an opening at one end, a cavity 21 communicated with the opening in the middle, and an outer cylinder 2 closed at the other end. Inducing particles, the wall of the outer cylinder 2 is provided with a plurality of release holes 22 communicating with the cavity and having a diameter not smaller than the inducing particles, the inducing particles are metal micron-sized particles, polyethylene micron-sized particles Or ceramic micron-sized particles, etc., the opening of the outer cylinder 2 is sealed by a seal. In this embodiment, the seal is a screw 1, and the inner wall of the outer cylinder opening is provided with an internal thread 11 that matches the screw 1 , the screw 1 rot...

Abstract

An animal intraosseous foreign body particle releasing device comprises an outer cylinder with one end open and the middle provided with a cavity communicated with an opening. The cavity is provided with inducing particles formed by at least one component of an artificial joint. The wall of the outer cylinder is provided with a plurality of release holes communicated with the cavity with the diameter less than the induced particles. The opening of the outer cylinder is sealed through a sealing member. The device can be used for preparation and basic research of a prosthesis aseptic loosening animal model and has the advantages of rapidness, stability and high repeatability.

Description

technical field [0001] The invention relates to a device for releasing foreign body particles in animal bones. Background technique [0002] Patients with joint pain and / or joint dysfunction caused by bone and joint system diseases and trauma generally consider artificial joint replacement to improve or even restore joint function and relieve pain. However, some patients will experience aseptic loosening of the artificial joint prosthesis after artificial joint replacement, and symptoms such as pain when the artificial joint moves. Aseptic loosening of the prosthesis refers to the aseptic inflammation induced by various micron-sized particles (including metal particles, polyethylene particles, ceramic particles, etc.) that appear around the prosthesis after artificial joint replacement. , and then induce periprosthetic osteolysis leading to prosthesis loosening, which is the main long-term complication after artificial joint replacement, seriously affecting the service life...
