Problems solved by technology

However, the existing synthetic mesh generally has low mechanical strength, which cannot well meet the requirements of human organ support, and the fabric is thick and heavy. After implanting into the human body, the patient's foreign body sensation is high, and the mesh has a low porosity. Defects that are not conducive to the exchange of substances for tissue growth

Embodiment approach

[0017] As a preferred embodiment of the present invention, the area of ​​each hexagonal mesh 2 is 4-18mm 2 , the weight per unit area of ​​the warp knitted mesh fabric 1 is 30-34 g / m 2 . This kind of mesh is light and thin, so that the patient feels less foreign body sensation during use.

[0018] In the present invention, the diameter of the polypropylene monofilament is 0.1-0.2mm, preferably 0.1mm, the breaking strength of the polypropylene monofilament is 5.70cN / dtex, and the elongation at break is 22.7%. Each of the The shape of the hexagonal mesh 2 is preferably a regular hexagon, and the area of ​​each hexagonal mesh 2 is preferably 5.8-16.2mm 2 , that is, the aperture (ie, circumcircle diameter) of each hexagonal mesh 2 is 3-5 mm. This kind of mesh is light and thin, and patients feel little foreign body sensation during use, and the mesh has a high porosity, with a porosity greater than 72%, which can well meet the requirements of light weight and tissue growth mate...

Abstract

The invention discloses a medical repairing mesh and a manufacturing method. The mesh is a warp knitted eyelet fabric formed by polypropylene monofilaments through warp knitting. The eyelet fabric comprises a plurality of hexagonal eyelets which are adjacent to one another and vertically arranged, and further comprises the polypropylene monofilaments enabling the hexagonal eyelets which are adjacent to one another and vertically arranged to be connected transversely and alternately. The diameters of the polypropylene monofilaments are 0.1-0.2mm, each hexagonal eyelet is in a regular hexagon shape, and the area of each hexagonal eyelet is 5.8-16.2mm*2. The mesh is high in mechanical strength and capable of completely meeting supporting requirements for human organs; the mesh is light and thin, so a patient feels slight foreign body sensation in a use process; the mesh is high in void ratio which is larger than 72%; in addition, the mesh is enlarged, meanwhile deformation in longitudinal and transverse directions of the mesh is reduced, and therefore the requirements of the mesh for a light weight and of tissue growth substances for exchanging can be better met, and tissue repair is facilitated.

Description

technical field [0001] The invention relates to a medical repairing mesh for repairing defects in various parts of a human body and a manufacturing method thereof, belonging to the technical field of biomedical materials. Background technique [0002] With the continuous development of material medicine, more and more materials have entered the medical field as biomedical materials to repair defects in various parts of the human body, and medical mesh is one of them. At present, medical mesh is the most widely used in general surgery, mainly used for the repair of various types of hernia, including inguinal hernia and incisional hernia, etc., and mainly used for chest wall reconstruction, diaphragm and pericardium repair in thoracic and cardiothoracic surgery. The application of brain surgery is mainly the repair of dura mater. In addition, medical mesh is mainly used in obstetrics and gynecology for female pelvic floor reconstruction, stress urinary incontinence, etc. The ...
