The invention relates to the technical field of barb cutting of medical sutures, and discloses a tension control method for barb cutting of medical sutures, which comprises the following steps: starting a double-rotor linear motor to slide a second slide block to a first slide block, starting a second clamping cylinder to clamp a thread end, transmitting tension of a suture to a tension sensor through a second turntable, and controlling the tension sensor to rotate; whether pre-cutting tension control needs to be carried out on the suture line is judged according to a numerical value fed back by the tension sensor, the first clamping air cylinder drives the cutter to move, and whether pre-cutting tension control needs to be carried out on the suture line is judged according to the numerical value fed back by the tension sensor. Whether barb cutting tension control needs to be carried out on the suture line or not is judged through a numerical value fed back by the tension sensor. The tension change in the bar
