3 results about "Surgical patch" patented technology

This invention relates to the field of medical devices, specifically to a patch application, its preparation method, and its application. The patch comprises an immediate-release layer, a cross-linking layer, and a sustained-release layer; the cross-linking layer is placed between the immediate-release and sustained-release layers, with the immediate-release layer in contact with the skin; the immediate-release layer comprises a first microsphere, which has a polyvinyl alcohol coating and an ibuprofen core; the cross-linking layer is a calcium ion cross-linked membrane obtained by cross-linking sodium alginate and calcium chloride; the sustained-release layer comprises a second microsphere, which has a polylactic acid-glycolic acid copolymer coating and a diclofenac sodium core. The patch application provided by this invention can rapidly reduce inflammation and pain through the anti-inflammatory and analgesic microspheres and maintain the surgical patch for a certain period of time, while also providing local physical cooling. Compared with traditional patches, it alleviates postoperative pain to a certain extent and accelerates wound healing.

The utility model relates to the technical field of ophthalmologic operation pasting films, and discloses an ophthalmologic shear-free operation pasting film which comprises a thin film, first glossy paper, second glossy paper, a tearing strip, protrusions, an adhesive strip, third glossy paper and an easy-to-tear opening, medical pressure-sensitive adhesive is arranged on one face of the thin film, the first glossy paper is bonded with the thin film through the medical pressure-sensitive adhesive, and the second glossy paper is bonded with the third glossy paper through the easy-to-tear opening. And the second glossy paper is bonded with the thin film through a medical pressure-sensitive adhesive. The utility model has the beneficial effects that the holes corresponding to the eyes are preset on the operation pasting film, the eyes can be exposed by directly taking down the stickers on the holes after the film is pasted, the use process of the operation pasting film is simplified, and meanwhile, the two pieces of smooth stickers are arranged on the sticky surface of the film, so that the operation pasting film is convenient to use. When the film is pasted, one smooth paster is taken down for preliminary positioning, and then the other smooth paster is taken down to complete integral pasting, so that the operation pasting film is more accurately pasted on the skin around the eyes of a patient, and the isolation effect and stability of the operation pasting film are improved.

A device for introduction and delivery of a self-adhesive surgical patch during minimally invasive surgery is disclosed. The device comprises a base that can be compressed to fit inside a 5 mm i.d. tubular member. In preferred embodiments of the invention, the base comprises a frame made of a compliant material. The patch is attached to the frame while the frame is in a planar open configuration. Pressure is then applied to opposite sides of the frame, compressing it to a linear closed configuration small enough to pass through a 5 mm i.d. tubular member. After passing through the tubular member, the frame is reopened to its open configuration, enabling delivery and attachment of the patch to a target tissue. A kit for providing the device is also disclosed.
