Suture cutter

Abstract

The invention provides a thread cutter, comprising a hard tube (1), the hard tube (1) is mainly composed of a tube body (11), a transition part (12), and a tube head (13) connected in sequence; The pipe (1) is provided with a pipe-through hole, and the pipe-through hole runs through the proximal end surface and the distal end surface of the hard pipe (1) along the axial direction of the hard pipe (1); the pipe head (13) is provided with sawtooth (2); one or more serrations (2) are arranged on the outer wall surface or the distal end surface of the pipe head (13); the serrations (2) are only on one of the circumferential directions of the hard tube (1) It can be cut when rotating; the pipe body (11), the transition part (12) and the pipe head (13) are integrally formed; or, the transition part (12) and the pipe head (13) are detachably connected. The present invention can penetrate into the surgical wound to cut off the suture from the drainage tube, preventing the tissue at the wound from being involved when the drainage tube is drawn out, thereby avoiding the risk of severe pain and wound deterioration for the patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a cord cutter. Background technique [0002] For example, after the completion of sacral tumor resection and reconstruction surgery, it is usually necessary to use a drainage tube to place in the wound, suture the wound layer by layer, and drain the internal pus in time. When the daily drainage volume is lower than a certain value, the drainage tube can be removed from the wound. pull out.
