Clip instruments and control methods thereof

A control method for a clip instrument, wherein:

• the clip instrument includes a clip device, a delivery device, and a control device, the clip device is releasably disposed at a distal end of the delivery device, the control device includes a control wire, the control wire includes a first control wire and a second control wire, the clip device includes a clip base and a clamping portion, the clamping portion includes a first clamping portion and a second clamping portion, a distal end of the first control wire is releasably connected to the first clamping portion, and a distal end of the second control wire is releasably connected to the second clamping portion;
• the control method comprises:
• controlling the first control wire to move from a proximal end to a distal end of the first clamping portion by the control device to cause the first control wire to drive the first clamping portion to deflect around an axis;
• and
• controlling the second control wire to move from a distal end to a proximal end of the second clamping portion by the control device to cause the second control wire to drive the second clamping portion to deflect around the axis;
• wherein a deflection direction of the first clamping portion and a deflection direction of the second clamping portion are the same, and the clip device deflects integrally.

A control method for a clip instrument, wherein:

• the clip instrument includes a clip device, a delivery device, and a control device, the clip device is releasably disposed at a distal end of the delivery device, the control device includes a control wire, the control wire includes the first control wire and the second control wire, the clip device includes a clip base and a clamping portion, the clamping portion includes a first clamping portion and a second clamping portion, a distal end of the first control wire is releasably connected to the first clamping portion, a distal end of the second control wire is releasably connected to the second clamping portion, and at least one of the first clamping portion or the second clamping portion includes a puncture member;
• the control method comprises:
• controlling the clip instrument to clamp a first target object at a first target position and causing the puncture member to penetrate into the first target object;
• controlling at least a portion of the clip device to move to a second target position, wherein the puncture member drives the first target object to move synchronously;
• and
• controlling the clip instrument to simultaneously clamp the first target object and a second target object.
