Abstract

The utility model provides an umbrella-type repairing component. The umbrella-type repairing component is characterized by comprising skeletons crossly fixed in longitudinal and horizontal directions, a surface layer arranged on the upper surface of the skeleton, an inner layer arranged on the lower surface of the skeleton, and a folding cone arranged in the middle of the inner layer, wherein the large end of the folding cone is connected with the middle part of the inner layer, and the small end of the folding cone is downward and connected with a guide line. Before using, the repairing component is a contracted umbrella body; when in use, the repairing component is naturally unfolded under the elasticity effect of elastic steel stainless stripes or plastic stripes and is dragged to a hernia endostoma position; the folding cone is placed in the hernia sac, and then the direct and indirect hernia triangular domains are covered through the umbrella cover so as to conveniently finish the herniorrhaphy. The repairing component provided by the utility model is simple in structure, convenient for operation, high in safety and reliability when in use, and cannot injure the around vessels and nerves.

Description

The umbrella shape repair piece

Technical field

This utility model relates to a kind of repair piece, and especially a kind of umbrella shape repair piece belongs to technical field of medical instruments.

Background technology

In prior art, the patch that is used for straight, the oblique hernia internal orifice of repairing adult has two kinds, and a kind of is can the plane sticking patch of the company of sticking not occur with surrounding tissue, need to use the titanium nail that it is mended on peritoneum during use, easily be pinned to subabdominoperitoneal blood vessel and nerve, and cause bleeding and pain.Another kind is the sticking patch that can cause the surrounding tissue adhesion, after must separating the peritoneum around the hernia internal orifice during use, then sticking patch is placed under peritoneum sews up, and can injure blood vessel and nerve equally, cause bleeding and pain, and complicated operation.When using, two kinds of sticking patch all need to open three holes at stomach wall, and extremely inconvenient.Therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to provide a kind of not injured blood vessel and nerve, and easy to operate, safe and reliable umbrella shape repair piece.

This utility model provides a kind of like this umbrella shape repair piece, it is characterized in that comprising the skeleton that longitudinal and transverse intersection is fixing, be located at respectively the surface layer of skeleton upper surface and the internal layer of lower surface, be located at the folding cone at internal layer middle part, should folding large end of cone be connected with the internal layer middle part, small end is downward, and be connected with messenger, so that after skeleton struts naturally, move in hernical sac by messenger, and folding cone is placed in hernical sac, cram hernical sac, again by umbrella cover straight, tiltedly the hernia Delta Region covers, repair thereby complete hernia.

Described skeleton is at least two elastic strips, intersects as stainless steel strip or plastic strip fixedly to form, conveniently to strut or shrink and prevent that umbrella cover from crispaturaing.

Described folding cone is a polypropylene disk, its disk peripheral intervals is set the site, by fixing of each anchor point, the disk periphery is drawn in and form folding cone, the gathering end of folding cone is fixed on corresponding internal layer middle part, and the cone small end is to downward-extension, and is connected with messenger, with convenient mobile, and can send into hernical sac and complete shutoff folding cone easily.

Described surface layer is the expanded PTFE sheet, and its fibre length can prevent that less than 3 μ m intraperitoneal is even glutinous.

Described internal layer is polypropylene foil, can stick together with surrounding tissue.

Described surface layer, internal layer and skeleton can be pruned as required,, tiltedly hernia Delta Region size requirements straight to adapt to.

the utlity model has following advantages and effect: adopt such scheme, can form the umbrella body of contraction, during use under the elastic reaction of elastic stainless steel bar or plastic strip, naturally strut, draw to hernia internal orifice position by messenger, and folding cone is placed in hernical sac, straight by the umbrella cover handle again, tiltedly the hernia Delta Region covers, thereby completing easily hernia repairs, add that internal layer tightly sticks at around the hernia internal orifice that is repaired, and can stick together with this surrounding tissue, surface layer can not stick together with surrounding tissue, thereby repair piece is securely fixed in around the hernia internal orifice, it is easy to operate simple again, not the more important thing is and can injure peripheral vessels and nerve, has higher safety, unfailing performance, be a desirable medical repair piece in fact.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is described further.

The umbrella shape repair piece that this utility model provides, comprise the skeleton 1 that longitudinal and transverse intersection is fixing, this skeleton 1 is that three elastic stainless steel bars intersections fixedly form, be located at respectively the surface layer 2 of skeleton 1 upper surface and the internal layer 3 of lower surface, surface layer 2 is the expanded PTFE sheet, its fibre length can prevent that less than 3 μ m intraperitoneal is even glutinous; Internal layer 3 is polypropylene foil, can stick together with surrounding tissue; Internal layer 3 middle parts are provided with folding cone 4, should folding cone 4 be a polypropylene disk, its disk peripheral intervals be set the site, by fixing of each anchor point, the disk periphery is drawn in and form folding cone 4, the gathering end of folding cone 4 is fixed on corresponding internal layer 3 middle parts, and cone 4 small ends are to downward-extension, and is connected with messenger 5, described surface layer 2, internal layer 3 and skeleton 1, all can prune as required, adapt to the hernia internal orifice size requirements that is repaired, as Fig. 1, Fig. 2, Fig. 3.

Claims

1. umbrella shape repair piece is characterized in that the skeleton that comprises that longitudinal and transverse intersection is fixing, is located at respectively the surface layer of skeleton upper surface and the internal layer of lower surface, be located at the folding cone at internal layer middle part, should folding large end of cone be connected with the internal layer middle part, small end is downward, and is connected with messenger.

2. umbrella shape repair piece according to claim 1, is characterized in that described skeleton fixedly forms at least two elastic strips intersect.

3. umbrella shape repair piece according to claim 1, it is characterized in that described folding cone is a polypropylene disk, the disk peripheral intervals is set the site, by fixing of each anchor point, the disk periphery is drawn in and form folding cone, the gathering end of folding cone is fixed on corresponding internal layer middle part, and the cone small end is to downward-extension, and is connected with messenger.
