The method provided by the embodiment comprises the following steps:

step 1, an operator holds the holding part 201 and sends the supporting rod 203 into a patient through a cavity mirror hole, so that the scribing part 204 can enter the patient;

step 2, finding the stomach under the endoscope, moving the supporting rod 203 to the position corresponding to the stomach, and enabling the scribing part 204 to be opposite to the position set by the outer surface of the stomach, namely enabling the scribing part 204 to move to the planned scribing position, so that the scribing part 204 is positioned above the planned cutting path, as shown in fig. 3;

step 3, the operator operates the grip 201 to make the scribing portion 204 contact and press the outer surface of the stomach (hereinafter also referred to as the stomach surface), so that a mark line 205 may be printed on the outer surface of the stomach by using the scribing portion 204, and for convenience of explanation, the mark line 205 may be referred to as a first mark line 205;

step 4, after the first marking line 205 is printed, the operator can operate the holding part 201 to separate the marking part 204 from the outer surface of the stomach, so that the first marking is completed, and then the operator can move the marking part 204 to one end of the first marking line 205, so that the next marking line 205 can be printed;
