Embodiment Construction

[0012] exist figure 1 Among them, the PLGA film on the smooth surface (1), the perfluorocarbon liquid and PLGA (2), and the PLGA film on the rough surface (3) are closely attached together from top to bottom to form a film.

[0013] exist figure 2 In the shown embodiment, the surface of the rough surface PLGA membrane (3) is densely covered with small protrusions (4) and small holes (5), and the small holes (5) communicate with the perfluorocarbon liquid (2) in the middle layer.

[0014] image 3 As shown in the sectional view, the hexagonal honeycomb cell (8) made of PLAG is filled with oxygen and the perfluorocarbon liquid (7), and the perfluorocarbon liquid (7) cannot pass through the honeycomb cell wall (6) .

[0015] exist Figure 4 In the longitudinal section structure shown, the two ends of the PLGA honeycomb cell wall are respectively fused with the smooth PLGA membrane (1) and the rough surface PLGA membrane (3), so as to ensure that the perfluorocarbon liquid (7...

Abstract

A surgical follow-up anti-adhesion, bacteriostasis and healing promotion pasting film which can be pasted to a postoperative internal organ stitching surface to prevent postoperative adhesion, inhibit bacteria and promote wound healing is composed of a smooth surface PLGA film, a honeycomb PLGA chamber filled with perfluorocarbon, and a rough surface PLGA film with protrusions and small holes. The surface of the rough surface PLGA is plastered to wounds after the wounds are stitched by a doctor.

Description

Technical field [0001] The invention relates to an anti-adhesion, antibacterial, and healing-promoting patch that is pasted on visceral wounds after suturing a visceral wound by a doctor in a hospital during an operation on a patient, in particular to an anti-adhesion, antibacterial, and healing-promoting patch after a surgical operation. It consists of a three-layer structure, in which the upper and lower layers are composed of smooth poly-DL-lactic acid-polyglycolic acid copolymer (PLGA) and rough surface PLGA, and the middle layer is composed of PLGA and perfluorocarbon. In the process of wound healing after surgery, it can separate the wound from surrounding tissues, prevent fibrous adhesion, inhibit bacterial growth, and promote wound healing. Background technique [0002] At present, it is well known that tissue adhesion is a common clinical phenomenon after surgery. Adhesive ileus can be caused after abdominal surgery, recurrent laryngeal nerve injury can be caused af...
