Suture cutter

Abstract

The invention provides a suture cutter which comprises a hard tube (1). The hard tube (1) is mainly composed of a tube body part (11), a transition part (12) and a tube head part (13) which are sequentially connected. A tube run-through hole is formed in the hard tube (1) and runs through the near end face and the far end face of the hard tube (1) in the axial direction of the hard tube (1). Sawteeth (2) are arranged on the tube head part (13). One or more sawteeth (2) are arranged on the outer wall surface or far end face of the tube head part (13). The sawteeth (2) can conduct cutting when rotating in one direction of circumferential directions of the hard tube (1). The tube body part (11), the transition part (12) and the tube head part (13) are integrally formed; or, the transition part (12) and the tube head part (13) are detachably connected. The suture cutter can extend into a surgical wound to cut off a suture from a drainage tube, it is avoided that tissue of the wound is dragged when the drainage tube is pulled out, and then the risk that a patient bears severe pains and the wound deteriorates is avoided.

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. In actual operation, it often happens that the drainage tube is sewn on the wound due to the doctor's hand or mistake. When the drainage tube is pulled out, the surrounding tissue of the wound is affected, causing great pain to the patient, and even causing serious deterioration of the wound. There is no tool or method for cutting the suture from the drainage tube in the prior art, and the drainage tube can only be pulled out forcibly, thereby producing the above-mentioned series of negative...
