The utility model content

The purpose of this utility model just provides and a kind ofly was not easy to the improvement operation sewing needle of taking out stitches at that time when occur sewing up.

For achieving the above object, improvement operation sewing needle of the present utility model comprises the needle body of being with pinprick, and it is characterized in that: needle tip has barb, is hinged with the barb lid on the needle body thereafter.

Described barb lid is hinged on the middle elongated slot of needle body, is the flat strip in end.

Described needle point is directly made the paracone barb.

The beneficial effects of the utility model are: because this novel improvement operation sewing needle needle tip has barb, be hinged with the barb lid on the needle body thereafter, connect the whole forward inserting needles of pin band wire when sewing up first pin and sew up the both sides knotting of passing wound, barb covers overturning backward and stretches flat during inserting needle, easy damaged flesh layer not, stitching afterwards just will all not passed wound by pin, need only pass the line that will stay homonymy behind the another side of wound at the barb of needle point hangs in the barb, then pin is returned and pull out, this moment, barb covered overturning forward, covered to make it can not hook flesh layer and the smooth back stitching of mucosa outside barb and tape is returned.So repeat to come and go to sew up at last and tie a knot, when occurring sewing up mistake, will not take out stitches by holostrome,, reach the otch hemostasis as long as the end of a thread is just cut off and can be taken out stitches easily, reduce otch open-assembly time, simplify stitching step, reduce the purpose that infects, and otch is to neat normally, and the end of a thread reaction is few, does not have scleroma and easily absorbs healing, also make effectively to occur sewing up not to be easy at that time take out stitches, alleviate puerpera's misery.
