Multi-modal visual patch fixing anchor and preparation method thereof

Abstract

The invention discloses a multi-modal visual patch fixing anchor and a preparation method thereof. The multi-modal visual patch fixing anchor comprises a disc and an anchor body which are connected into a whole; the disc at the top end of the anchor is provided with a micro air bag structure; the anchor body adopts a three-jaw form, the angle between every two jaws is 120 degrees, and a hook-shaped inclined tip is arranged at the bottom end of each jaw; and the disc and the anchor body are both made of PLGA materials. According to the multi-modal visual patch fixing anchor, the three-jaw structure of the multi-modal visual patch fixing anchor can stretch across and be fixed to the two edges of meshes of the patch under any circumstances, the stability is high, the fixing effect on the edge of the implanted patch is good, the problems of patch displacement and shrinkage are reduced, the anchor is small in size, small in exposure area and light in foreign body sensation, and the comfort of a patient is greatly improved. In addition, the micro air bag structure is arranged in the anchor, so that ultrasonic development is easy, and the problem that imaging detection of common products is difficult can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multimodal visual patch fixation anchor and a preparation method thereof. Background technique [0002] Abdominal wall incisional hernia is a complication of the incision after abdominal surgery. Because the incision site is relatively weak, the tissue will protrude outward through the incision site, and its incidence rate is as high as 30%. The traditional abdominal wall hernia repair is to forcibly pull the two ends of the defect together with sutures. There is tension, which is not in line with the physiological condition, and it is easy to relapse. After the operation, the patient suffers a lot of pain, the recovery time is long, and intestinal adhesion is prone to occur. It is not suitable for people who use it. many. Then there was tissue mesh hernia surgery, which is currently considered the most reasonable operation. After the completion of hernia mesh repair, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-modal visual patch fixation anchor and its preparation method, so as to solve the problems of anchor implanted patch fixation, patch displacement and shrinkage, and patch fixation existing in the above-mentioned prior art. In order to solve problems such as patch detection and imaging, the present invention is based on the multi-modal visual patch fixing anchor. The three-claw structure of the anchor can cross the two sides of the mesh fixed to the patch under any circumstances, and the stability is strong. The fixation effect of the edge of the patch is good, reducing the displacement and shrinkage of the patch, the anchor is small, the exposed area is small, and the foreign body sensation is light, which greatly improves the comfort of the patient
