Problems solved by technology

However, after the existing implants are implanted into the living body, when the fixed place is stressed, the implants are prone to prolapse along the original implantation path.
In addition, when the fixation site contains soft tissue, the existing technology needs to use degradable materials for fixation. The medical community still has doubts about the impact of degradable materials on the organism, for example, it will remain in the organism and cannot be discharged smoothly, or cause biological damage. possibility of cytopathic
[0003] Furthermore, after the implant is implanted in the living body, if adverse reactions occur, it needs to be removed, and there is no suitable device to easily remove the implant, which often causes damage to the biological tissue

Abstract

The invention discloses a bionic fixing device and a pulling-out device thereof, comprising a body with a through hole and at least one slit. The through hole runs through the top surface to the bottom surface of the main body to form a top surface opening and a bottom surface opening, and the inner diameter of the top surface opening is larger than the inner diameter of the bottom surface opening. The slit communicates with the bottom opening, and the slit extends upward from the bottom of the body so that the body has a flexible bottom.

Description

technical field [0001] The invention relates to a bionic fixing device and its pulling-out device, in particular to a bionic fixing device with a flexible bottom and its pulling-out device. Background technique [0002] With the advancement of technology and medicine, implants such as bone nails are used to fix tissues in living organisms for medical purposes such as repairing accidental injuries or natural aging. However, after the existing implants are implanted into the living body, when the fixed part is stressed, the problem of the implants protruding along the original implantation path is prone to occur. In addition, when the fixation site contains soft tissue, the existing technology needs to use degradable materials for fixation. The medical community still has doubts about the impact of degradable materials on the organism, for example, it will remain in the organism and cannot be discharged smoothly, or cause biological damage. Possibility of cell disease. [00...
