How long can titanium clips fall off in the body, which depends on the different tissues clamped in the body, whether the patient has serious infection in the body and other factors to make an objective analysis: a. If the titanium clips in the body clamped the local blood vessels, local infection does not occur obviously. In this case, about 2-3 months after the operation, the local wound can be completely healed and the titanium clip can fall off by itself, which will not cause the blood vessel to bleed again. Second, if the bile ducts and part of the intestinal ducts in the body are clamped by the titanium clamps, the trauma surface becomes infected after surgery, which causes the local trauma surface to take significantly longer to heal. In this case, the trauma can be completely healed in about 6 months after surgery, and the titanium clips can fall off by themselves without causing serious complications.
