Example 2
The main difference between the present embodiment 2 and the above embodiment 1 is that the pulling clamp for laparoscopic surgery provided in this embodiment further includes a movable adjustment mechanism 501, as shown in fig. 3, 4 or 5, where the movable adjustment mechanism 501 is used to adjust the hinge positions of the two handles; through adjusting the articulated position of two handles, can change the distance between two handles to can effectively adjust under the same angle of opening, the clamp force (restoring force) between two gripping heads 201, thereby make at the in-process of this tractive clamp of in-service use, the user can be according to the thickness of tissue or organ (for example according to the thickness difference of blood vessel), adjust the clamp force between two gripping heads 201, not only can effectively avoid appearing the clamp force too big, cause tissue and organ damage, and the practicality is stronger, and it is more convenient to use, be favorable to expanding this tractive clamp's application occasion.
In a preferred scheme, one end of the first operating handle 101 is provided with a hinge head 502, one end of the second operating handle 102 is provided with a connecting sheet 503, the connecting sheet 503 is provided with an adjusting chute 504 and a plurality of hinge holes 505, each hinge hole 505 is respectively communicated with the adjusting chute 504, the hinge head 502 is arranged in the hinge holes 505 and forms a hinge, and the hinge head 502 can be replaced from one hinge hole 505 to the other hinge hole 505 through the adjusting chute 504, so that the function of adjusting the hinge position is realized.
As an example, as shown in fig. 3,4 or 5, the pulling clamp provided in the present embodiment includes three hinge holes 505, and a tooth-shaped protrusion 506 is disposed between the three hinge holes 505, and the tooth-shaped protrusion 506 is used to prevent the hinge 502 from automatically sliding out of the hinge hole 505.
In a preferred embodiment, as shown in fig. 3, 4 or 5, one side of the tooth-shaped protrusion 506 is a circular arc-shaped structure 507 so as to be matched with the hinge 502, so that the hinge 502 is more convenient to rotate relative to the hinge hole 505; the other side is a planar structure 508, which has a guiding function, so that the hinge 502 can slide out of the current hinge hole 505 under the action of external force and slide along the chute towards the adjacent hinge hole 505, thereby effectively changing the hinge position.
In a preferred embodiment, the second lever 102 and the connecting piece 503 may be an integrally formed member.
As shown in fig. 4 and 5, in this embodiment, the hinge 502 may preferably have a cylindrical structure, one end of the hinge 502 is connected to the first handle 101, and the other end is provided with an annular blocking piece, so as to prevent the hinge 502 from falling out of the adjusting chute 504 or the hinge hole 505.
In this embodiment, since the spring piece 301 has an arc structure, as shown in fig. 3 or fig. 4, when the spring piece 301 is pressed by an external force, bending deformation occurs, so as to generate an elastic force, and the component force of the elastic force along the length direction of the pulling clamp causes the first operation handle 101 and the second operation handle 102 to have a tendency to be separated from each other, so that the first operation handle 101 and the second operation handle 102 can be pressed against each other at an end far from the clamping head 201, in this embodiment, the hinge hole 505 is disposed at an end far from the clamping head 201 on the adjusting chute 504, so that the hinge joint 502 on the first operation handle 101 can be pressed against an upper portion (i.e., an end far from the clamping head 201 on the hinge hole 505) and a right portion (i.e., an end near to the first operation handle 101 on the hinge hole 505) of the hinge hole 505, thereby realizing hinge.
When the hinge position is located at the hinge hole 505 on the outermost side (i.e., the side far from the second operation handle 102), at this time, the pressing force corresponding to the same opening degree is the largest, and when the pressing force needs to be reduced (i.e., when the hinge position is adjusted from the outermost side to the inside hinge hole 505), at this time, the first operation handle 101 is manually moved a little with respect to the length direction of the second operation handle 102, so that the hinge joint 502 is withdrawn from the current hinge hole 505 and enters the adjusting chute 504, and then the first operation handle 101 is manually moved in the direction far from the second operation handle 102, so that the hinge joint 502 is clamped into the inside hinge hole 505, and the adjustment is completed; when the hinge position is located at the hinge hole 505 at the innermost side (i.e. the side far away from the second operating handle 102), as shown in fig. 4 or fig. 5, at this time, the pressing force corresponding to the same opening degree is the smallest, and when the pressing force needs to be increased (i.e. when the hinge position is adjusted from the innermost side to the outer side of the hinge hole 505), at this time, one ends of the first operating handle 101 and the second operating handle 102 far away from the clamping head 201 are manually pressed, so that the hinge head 502 moves outwards under the guiding action of the toothed protrusion 506 and is clamped into the adjacent or outermost hinge hole 505, thereby conveniently realizing the adjustment of the hinge position.
As shown in fig. 3, 4 or 5, in a further aspect, the device further comprises a connecting ring 601, the connecting ring 601 may be fixed on the first handle 101 or the second handle 102, in a preferred aspect provided by the present embodiment, the connecting ring 601 is fixed on the connecting piece 503, and the connecting ring 601 is used for connecting a traction wire; for example, in the endoscopic surgery, one end of the traction wire can be conveniently sleeved on the connecting ring 601, so as to realize connection between the connecting wire and the traction clip, and the other end of the connecting wire is usually provided with a puncture needle; then the traction clamp is sent into the body of the patient through a cavity mirror hole arranged on the abdomen of the patient, and the tissue to be clamped by the traction clamp is utilized; finally, the puncture needle passes through the abdomen of the patient from inside to outside, and the puncture needle or the traction wire which passes out of the body is fixed (namely, the external fixation is realized), so that the traction of tissues or blood vessels can be realized very conveniently, the surgical field of laparoscopic surgery is increased, in addition, the external traction mode provided by the embodiment does not occupy a endoscopic hole, does not interfere other surgical operations, and is beneficial to realizing the hole-reducing or single-hole laparoscopic surgery.
