Detailed Description
In order to clearly illustrate the technical characteristics of the present solution, the present solution is described below by means of specific embodiments and with reference to the accompanying drawings.
As shown in the figure, the suture knot-tying device for laparoscopic surgery comprises a handle part 5, a rod body 2 and a knot-tying part 1, wherein a rotator 4 which is adapted to an index finger is fixedly connected to the outer side of one end, close to the handle part 5, of the rod body 2, and the knot-tying part 1 comprises two wire clamping pliers 13 which are hinged with the end part of the rod body 2 and can be driven to open and close by the handle part 5. When the jaws of the two wire clamping pliers 13 are closed, the knotting part 1 is in a spiral shape, so that when the rotator 4 drives the knotting part 1 to rotate through the rod body 2, the suture is spirally wound on the knotting part 1, the suture cannot fall off, and the winding step is completed. And when the jaws of the two wire clamps 13 are closed, the end part of the knotting part 1 is in a tip shape, and the structure is favorable for knotting by clamping the suture with the two wire clamps 13.
The handle part 5 comprises a fixed handle 6 and a movable handle 7, one end of the movable handle 7 stretches into the inner cavity of the fixed handle 6, and the middle part of the movable handle 7 is hinged with the fixed handle 6, so that the movable handle 7 can rotate around the hinge point of the movable handle 7 and the fixed handle 6.
The rod body 2 is internally provided with a guide rod 3 in clearance fit with the rod body, one end of the guide rod 3 is hinged with the movable handle 7, and the other end of the guide rod is hinged with the two wire clamping pliers 13 through a connecting rod mechanism. One end of the movable handle 7 connected with the guide rod 3 is also connected with a return spring 8, and the other end of the return spring 8 is connected with the inner wall of the fixed handle 6.
The link mechanism comprises a link A11 and a link B12, wherein the link A11 is hinged with the lower part of the guide rod 3, the link B12 is hinged with the upper part of the guide rod 3, and the other ends of the link A11 and the link B12 are respectively hinged with the end parts of the two wire clamps 13.
