Centrum injection dilator and manufacture method thereof

Abstract

The invention provides a centrum injection dilator which can effectively prevent a biological material from outwards leaking from gaps on centrum before the biological material is cured and avoids remaining other built-in materials except for the biological material in the centrum. According to the centrum injection dilator provided by the invention, the centrum injection dilator is provided with a saccule, the saccule is provided with an injection port and a saccule body, the saccule is suitable for containing the curable biological material injected from the injection port, the saccule bodyis provided with an opening, the size of the opening is set to be allow the cured biological material in the saccule to separate from the opening, the opening is closed by an adhering material to form a complete saccule shape, and the adhering material has a softening point with a preset temperature value within a heat release temperature range in a curing heat release process of the biological material.

AI Technical Summary

Benefits of technology

This patented device helps keep blood clots away during spine surgeries by making it easier for them to break up when they hit bone tissue inside their joints instead of getting stuck together with surrounding parts like metal or plastic tools that may be harmful if left behind permanently.

Problems solved by technology

There have been technical drawbacks associated with current methods involving introducing an artificial substance inside the patient's body during orthopedic procedures like fusion surgeries. These techniques involve injecting fluoroscopic gelatin particles directly into the posterior portion of the subject undergoing therapy without allowing any gas pressure to enter them. However, they may lead to leakages around the edges where the gelatin hardens over time, making removal of the prosthesis challenges. Additionally, previous designs require complex fabrication processes, leading to potential issues including difficulty extracting the necessary components needed for effective use within the body being treated.
