The invention relates to a suture device which is applied to surgical operations, the suture device comprises a thread picking up device, a needle holding device and a suture needle. The suture device also comprises a movable handle and a fixed handle which form joint each other and a spring which is arranged between the movable handle and the fixed handle. The thread picking up device comprises an outer tube with an outlet pinhole, a pull rod for picking up thread which is arranged in the outer tube and a thread picking up mechanism. The needle holding device comprises the tube of the needle holding device and a needle holding pull rod and an elastic pull rod which are arranged in the tube of the needle holding device. The back end of the thread picking up pull rod forms the joint with the movable handle. The back end of the suture needle is connected with the front end of the elastic pull rod. The back end of the elastic pull rod is connected with the needle holding pull rod. The back end of the needle holding pull rod forms the joint with the movable handle. The front end of the tube of the needle holding device extends a stylophore, the front end of which is opened with a pinhole for the suture needle to go in and out of the stylophore. When not in use, the suture needle is arranged in the stylophore, thereby effectively preventing medical staff from being stabbed by the pin of the needle. The suture device has the advantages of slender structure, which is applied to the suturing in deep and narrow operation regions.
Description
technical field [0001] The invention relates to a medical instrument for surgical operation, in particular to a stapler. Background technique [0002] In surgery, suturing various parts is one of the most basic operations. Traditional suturing instrument is made up of needle holder, suture needle and suture thread, and the needle eye of suture needle is positioned at its tail end. During the suturing process, the instrument nurse holds the needle holder to hold the suture needle with sutures, and then passes it to the surgeon. The surgeon inserts the needle from one side of the tissue to be sutured, and the needle passes out from the other side of the tissue to be sutured. Then loosen the needle holder, and then use the same needle holder to hold the pierced needle point, pull out the needle, and at the same time bring out the thread through the end of the needle, pull the thread out from the eye of the needle, and then connect the needle holder belt The needle is handed t...
