In this embodiment, the improved clamp 200 includes a connecting arm 201 and a working arm 202, where the dimension of the connecting arm 201 is smaller than the dimension of the working arm 202, so that a staggered shoulder is formed between the connecting arm 201 and the working arm 202 due to the different dimensions.

The elastic pull member 100 is formed of a first positioning ring member 110 and a second working ring member 120, which may be closed or non-closed loop structures. In this embodiment, the first positioning ring 110, the second working ring 120 and the transition portion are all elastic, so as to form an elastic pulling member 100.

The first positioning ring 110 is used to be sleeved on the clamp 200, i.e. sleeved on the connecting arm 201. In this embodiment, the size of the first positioning ring 110 is matched with the outer peripheral size of the connecting arm 201, so that the first positioning ring 110 can be just sleeved on the connecting arm 201, and the stop shoulder between the connecting arm 201 and the working arm 202 can just ensure that the first positioning ring 110 cannot easily slip. Better use effect is achieved, so that the connection between the first positioning ring 110 and the clamp 200 is more stable and firm.

In this embodiment, the second working ring 120 is generally connected to the other clamp 200, that is, in a conventional digestive endoscopy operation, when the hemostatic clamp is pulled in the digestive endoscopy operation, the second working ring 120 is mainly used for the operation in the operation, is sleeved on the clamping arms of the other clamp 200, and is matched with the first positioning ring 110, and the whole elasticity of the elastic pulling member 100 is utilized to achieve the pulling of the human tissue.

As an alternative implementation of this embodiment, the first positioning ring 110 includes a flat edge 113, and the connecting arm 201 is flat, and the flat edge 113 matches with the flat surface. Since the clamping arms of the existing clamp 200 are mostly flat, in this embodiment, the connecting arms 201 are also flat, so that the structure of the original clamp 200 can be maintained as much as possible, and the improvement cost is reduced. Meanwhile, since the first positioning ring 110 is correspondingly provided as the flat edge 113 based on the flat shape of the connection arm 201, so that the first positioning ring 110 is more matched with the connection arm 201, the gap between the first positioning ring 110 and the connection arm 201 can be reduced, so that the elastic pulling member 100 is less prone to the disengagement of the clamp 200.

As an optional implementation manner of this embodiment, the first positioning ring 110 further includes a first short side 111 and a second short side 112, where the first short side 111 and the second short side 112 are respectively disposed at two ends of the flat side 113 perpendicularly, and further includes a converging portion, where the converging portion is connected to both the first short side 111 and the second short side 112, and the converging portion, the first short side 111, the second short side 112, and the flat side 113 form a closed or open structure, and the closed or open structure is matched with the connecting arm 201. In this embodiment, the constriction portion, the first short side 111, the second short side 112 and the flat side 113 form a closed or open structure, and the closed or open structure is just matched with the external dimension of the connecting arm 201, so that the requirement of sleeving the connecting arm 201 can be met, and the external dimension of the working arm 202 is not excessively large, so that the elastic pulling member 100 and the clamp 200 are prevented from slipping.

As an alternative implementation of this embodiment, the lengths of the first short side 111 and the second short side 112 are adapted to the thickness of the connecting arm 201. In connection with the above embodiment, the lengths of the first short side 111 and the second short side 112 are adapted to the thickness of the connecting arm 201, so that the first positioning ring 110 is less likely to slip off the clamp 200.

As an alternative implementation manner of this embodiment, the converging portion includes a straight edge 114, where the straight edge 114 is disposed parallel to the flat edge 113, and the straight edge 114, the first short edge 111 and the second short edge 112 of the flat edge 113 form a rectangular structure. In this embodiment, the first short side 111 and the second short side 112 of the straight side 114 and the flat side 113 form a rectangular structure, and in combination with the above embodiment, the connecting arm 201 is also flat, and the lengths of the first short side 111 and the second short side 112 are adapted to the thickness of the connecting arm 201, so that the rectangular structure is just adapted to the external dimension of the connecting arm 201, and just can be sleeved outside the second connecting arm 201, without being excessively larger than the external dimension of the working arm 202, thereby avoiding the elastic pulling member 100 from slipping off the clamp 200.

As an alternative implementation manner of this embodiment, the transition portion is a solid segment 130, one end of the solid segment 130 is connected to the straight edge 114, and the other end of the solid segment 130 is connected to the second working ring 120. The embodiment is an implementation manner of the transition portion, that is, the transition portion is the solid segment 130, and the structure is simple, so that not only the connection strength is ensured, but also a smaller volume is ensured, and the operation in the operation is facilitated.

As an alternative implementation of this embodiment, the second working ring 120 is a closed ring, and the closed ring is connected to one end of the solid segment 130. The embodiment is an implementation of the second working ring 120, i.e. a conventional closed ring, which has a simple structure, is easy to process, and is convenient to cooperate with other clamps 200, thereby facilitating the operation during surgery.

In this embodiment, the first arc edge 131 and the second arc edge 132 are relatively protruded to form a smaller envelope structure, which is also beneficial to avoiding the sliding of the elastic pulling member 100 and the clamp 200 because the structural dimension is not too large or even larger than the external dimension of the working arm 202 when the elastic pulling member is sleeved outside the second connecting arm 201.

As an optional implementation manner of this embodiment, the second working ring 120 includes a third arc-shaped edge 133 and a fourth arc-shaped edge 134, and the transition portion is a rounded transition between the first arc-shaped edge 131 and the third arc-shaped edge, and a rounded transition between the second arc-shaped edge 132 and the fourth arc-shaped edge 134. The second working ring 120 of the present embodiment includes a third arcuate edge 133 and a fourth arcuate edge 134, and the annular structure formed by the third arcuate edge 133 and the fourth arcuate edge 134 can be used to cooperate with other forceps 200 to perform an intraoperative procedure. It is conceivable that, based on the above embodiment, the first arc-shaped edge 131 and the third arc-shaped edge are smoothly transited, and the second arc-shaped edge 132 and the fourth arc-shaped edge 134 are smoothly transited, so that the second working ring 120 and the first positioning ring 110 have better integrity and are easy to process.
