RU47681U1 - CONNECTING ELEMENT FOR INTERNAL BODIES POLYMERIC - Google Patents

Abstract

The utility model relates to medical equipment and can be used in general surgery to connect soft tissues and internal organs. The utility model is a rectangular plastic sheet with geometric dimensions: length from 10 to 150 mm; width from 10 to 100 mm; thickness from 0.05 to 0.5 mm made from a copolymer of vinylpyrrolidone with butyl methacrylate.

Description

The utility model relates to medical devices, namely to products used in general surgery.

It is known to use collagen films as connecting elements for connecting soft tissues and organs. Lutsevich O.E., Petrov V.I. and others. "The use of complex collagen film for the prevention of intestinal suture failure." Council, Medicine, 1989, N3, pp. 54-58. However, the use of such elements has a number of disadvantages:

- Collagen films made from animal tissue are capable of exerting unwanted immune responses.

- Collagen films have low mechanical strength and quickly lose it when in the body, which does not always ensure reliable retention of tissues during the regeneration period.

- Collagen films do not interfere, and sometimes contribute to the formation of adhesions between various tissues and organs.

- Collagen films, due to their animal origin have a short term

storage.

The technical task of the proposed utility model is the ability to create connecting elements for internal organs and tissues from biodegradable synthetic polymers with high biocompatibility, high strength characteristics, providing high reliability of fixation of soft tissues, preventing the formation of adhesions, capable of providing local and with the ability to maintain their properties during long-term storage .

The technical result is achieved in that the utility model is made in the form of rectangular plates with geometric dimensions

length mm from 10 to 150 width mm from 10 to 100 thickness mm from 0.05 to 0.5

made from a copolymer of vinylpyrrolidone with butyl methacrylate PPB-1.

The essence of the utility model is that the connecting element is capable of biodegradation within the body, to ensure reliable retention of dissected soft tissues, to provide physical and biological integrity of the joints, to provide anti-adhesion action.

The essence of the utility model lies in the fact that the element is made of a biodegradable synthetic polymer with high physical and mechanical characteristics and optimal hydrophilicity, which ensures high elasticity of the product, minimal tissue reaction.

The use of the proposed connecting element provides reliable retention of dissected tissues and organs, a minimal tissue reaction of the surrounding tissues, a disintegrating effect, excluding the occurrence of the adhesive process, physical and biological integrity of the joints.

The utility model operates as follows.

After resection and the formation of the ligature suture on the operated organ, the connecting element is placed for 3-5 minutes in a sterile physiological saline solution, it is removed, a section of the required dimensions is cut out, the surface of the element and the ligature suture is dried with a swab, medical glue is applied (MK-7 M, MK- 8 or others), impose an element on the wound surface and lightly press for 30-40 minutes. Several elements can be applied to wounds of complex configuration, laying them according to the "tile" principle, then the wound is sutured in layers.

Utility Model Manufacturing Examples

Example No. 1

From a solution consisting of 25 ml of ethyl alcohol, 9 g of PPB-1 copolymer (90%), a film 50 μm thick is formed by irrigation and the connecting elements are cut from it with a length of 10 mm and a width of 30 mm.

Example No. 2

From a solution consisting of 20 ml of ethyl alcohol, 7 g of PPB-1 copolymer (70%), a film with a thickness of 150 μm is formed by irrigation, from which the connecting elements are cut 150 mm long and 100 mm wide.

Example No. 3

From a solution consisting of 20 ml of ethyl alcohol, 5 g (50%) by irrigation, a film 0.5 mm thick is formed, from which elements 30 mm long and 10 mm wide are cut.

Claims (1)

A connecting element for internal organs and tissues made of polymeric materials, characterized in that it is made in the form of rectangular plates with geometric dimensions length mm from 10 to 150 width mm from 10 to 100 thickness mm from 0.05 to 0.5 made from a copolymer of vinylpyrrolidone with butyl methacrylate PPB-1.
