1. A minimally invasive knotter, comprising a first forcep handle (1), a second forcep handle (2), and a clamping head (3); middle parts of the first forcep handle (1) and the second forcep handle (2) intersect and are connected in a hinged manner, the first forcep handle (1) is provided with an installation head (4), and a rotating rod (5) is spherically hinged to the installation head (4); the clamping head (3) is connected to the rotating rod (5);
the second forcep handle (2) is provided with a limiting clamp (6) and a moving component (7); one side of the limiting clamp (6) is provided with an opening capable of catching the clamping head (3); the limiting clamp (6) is connected to the second forcep handle (2) through the moving component (7) so as to limit the clamping head (3) to work at a set angle; and
an end part, backing away from the rotating rod (5), of the clamping head (3) is provided with two clamping rods (31), and under the action of a power component (8), the two clamping rods (31) are able to approach to or back away from each other to achieve clamping and releasing of a suture line.
