The invention discloses a thread cutting device which comprises a handle arranged at the near end of the thread cutting device. The sheath is arranged at the far end of the wire cutting device, the sheath is tubular, a window is formed in the side wall of the sheath, and a wire body is used for penetrating through the sheath from the window; the cutting piece is fixed in the sheath and comprises a cutting edge which is used for cutting the wire body and faces the far end; and the sliding block is arranged in the sheath, a wire body in the sheath is connected with the sliding block, and the sliding block drives the wire body to slide towards the near end relative to the sheath under the control of the handle, so that the wire body is in contact with the cutting edge. According to the suture cutting device, the size of the sliding block can be designed according to actual needs, on the basis that the operation safety is guaranteed, the reserved length of the suture tail after suture cutting can be short, the suture tail absorption time can be shortened, and the foreign matter reaction caused by remaining of the suture body is reduced.
Description
technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a thread cutting device. Background technique [0002] During surgery, after knotting to hold the thread in place, the excess thread needs to be removed. This can be done using scissors or similar tools during open surgery or on the surface of the skin. In minimally invasive surgery, however, most of the work is done through small openings such as cannulas, and standard surgical scissors are too large to cut through the openings to remove the wire body. [0003] Devices have been developed that have the ability to cut the wire body by means of a mechanism provided on the end of a long rod that fits into these confined spaces. When the thread is trimmed, these devices can easily cause the indwelling thread knot to be too long, making the absorption time of the thread knot long, and the foreign body of the indwelling thread is likely to cause a foreign body...
