Development optilene mesh and preparation method thereof

Abstract

The invention discloses a development optilene mesh. The development optilene mesh is prepared by mixing polypropylene with titanium alloy granules through a filling modification technology. The development optilene mesh is prepared through the following steps of adopting an atomization method by crushing liquid metal into powder by high-speed jet to obtain ideal titanium alloy powder; sufficiently stirring a coupling agent with the titanium alloy powder to obtain a mixture, performing drying and cooling, mixing the cooled mixture with polypropylene and an antioxidant in a ventilated chamber,performing vacuum drying at 80 DEG C, adding the mixture in a double screw extruder, performing extruding and granulation, and performing vacuum drying at 80 DEG C to remove moisture; and placing thedried granules in an injection molding machine, and performing wire drawing and knitting to obtain the mesh, so as to obtain finished products. Through the scheme, the titanium alloy granules are usedfor filling the polypropylene, so that the obtained mesh has good properties of the polypropylene, the strength and the compressive resistance of the mesh are reinforced, besides, the shape fixednessis reinforced, and shift and deformation are not easy; and besides, the development optilene mesh has development functions under images. Visual observation assessment after an operation and postoperative review is facilitated.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a developing hernia patch and a preparation method thereof. Background technique [0002] Polypropylene hernia mesh is currently the most commonly used mesh, but some hernia patients are prone to recurrence after surgery, especially hernias with large abdominal wall tissue defects, because of large tissue defects and excessive pressure on the protruding part, but polypropylene hernias Insufficient mesh strength leads to recurrence; at the same time, some patients with hernia recurrence are due to the displacement of the hernia mesh, because the hernia mesh is often removed due to postoperative pneumoperitoneum, or postoperative excessive activity, and postoperative field leakage. The hernia mesh may be curled or shifted after it is put in place due to fluid and other conditions. This process may occur immediately after the pneumoperitoneum is removed, or it may be due to the inte...

[0002] Polypropylene hernia mesh is currently the most commonly used mesh, but some hernia patients are prone to recurrence after surgery, especially hernias with large abdominal wall tissue defects, because of large tissue defects and excessive pressure on the protruding part, but polypropylene hernias Insufficient mesh strength leads to recurrence; at the same time, some patients with hernia recurrence are due to the displacement of the hernia mesh, because the hernia mesh is often removed due to postoperative pneumoperitoneum, or postoperative excessive activity, and postoperative field leakage. The hernia mesh may be curled or shifted after it is put in place due to fluid and other conditions. This process may occur immediately after the pneumoperitoneum is removed, or it may be due to the intense activity and seepage in the later stage, resulting in the inability of the hernia mesh to fully fit. However, because the polypropylene hernia mesh does not develop and is placed in the abdominal wall, it cannot be observed by imaging and naked eyes
