In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example, see Figures 1 to 12 A traction and fixation device for surgical operation includes an oval ring-shaped chuck 1 fixed to one end of a handle assembly. Further, the handle assembly includes a clamping handle 13 fixed to one end of the oval ring-shaped chuck 1. There are two clamping handles 13. The two clamping handles 13 are cross-stacked and arranged. The inner walls of the intersection of the two clamping handles 13 are connected by a hinge shaft, and a trigger groove 2 is opened on the side of the clamping handle 13.

[0020] A further advantage of adopting the above method is that the end of the clamping handle 13 away from the oval ring chuck 1 is a finger hole, and the two oval ring chucks 1 can be triggered to move closer or farther away by relative movement of the two clamping handles 13. The two trigger rods 14 move closer to each other and are squeezed against each other, so that the end close to the oval ring chuck 1 is lifted, thereby driving the touch ring 5 located in the outer ring through groove 3 and the propulsion ring 17 located in the center through groove 6 to move, and the contact surface of the two trigger rods 14 is a damping surface.

[0021] There are two oval ring chucks 1, and a trigger groove 2 is opened on the side of the handle assembly, and one end of the trigger groove 2 is opened at one end of the oval ring chuck 1, and the inner wall of the trigger groove 2 is hinged with a trigger assembly through an axis. Furthermore, the trigger assembly includes a trigger rod 14 hinged to the inner wall of the trigger groove 2 through an axis, one end of the trigger rod 14 passes through the trigger groove 2 and fits tightly on the bottom side of the lifting trigger ring 5, and a compression spring 15 is fixed between the side of the trigger rod 14 and the inner wall of the trigger groove 2.

[0022] Further advantages of adopting the above method are: by squeezing the two trigger rods 14 close together, the central trigger block 8 connected to the propulsion ring 17 can be pushed out to fit on the surface of the organ, thereby increasing the friction when pulling the organ and reducing the risk of the organ slipping out from between the two oval ring-shaped chucks 1, and the tightening arc plate 4 connected to the lifting trigger ring 5 can be pushed out from the outer ring position through the groove 3 to reduce the aperture of the outer side of the center hole of the oval ring-shaped chuck 1, thereby reducing the probability of the oval ring-shaped chuck 1 slipping out when pulling the organ, and at the same time, objects cut off from the organ can be protected to prevent the cut objects from falling off.

[0023] An outer ring position through groove 3 is provided on the inner side wall of the center hole on the back-to-back sides of the two oval ring chucks 1. The outer ring position through groove 3 is connected with the trigger groove 2. The outer ring position through groove 3 is located at one end of the center hole of the oval ring chuck 1 and is a plurality of through holes arranged in a circular array. The bottom of the outer ring position through groove 3 is an annular through hole. The inner walls of the through holes of the outer ring position through groove 3 are all plugged with tightening arc plates 4. The top of the tightening arc plate 4 is connected to the outer ring position through groove 3 through a limiting assembly. Furthermore, the limiting assembly includes a limiting slider 16 fixed to the surface of the tightening arc plate 4. The top of the limiting slider 16 is connected to the inner wall of the outer ring position through groove 3 through a sliding groove.

[0024] A further advantage of adopting the above method is that the limiting slider 16 can ensure that the tightening arc plate 4 can smoothly protrude from the end of the outer ring position through groove 3 to form a small-aperture circular ring, and the two sides of the protruding end of the tightening arc plate 4 are inclined surfaces, so that it is easy to protrude from the inner wall of the outer ring position through groove 3 and then be spliced ​​into a small-diameter ring groove.

[0025] The bottom inclined surface of the tightening arc plate 4 is tightly fitted with a lifting trigger ring 5, and the inner wall of the lifting trigger ring 5 is sleeved on the inner wall of the annular through hole at the bottom of the outer ring through groove 3. The inner wall of the center hole on the opposite side of the two oval ring chucks 1 is provided with a center through groove 6. The center through groove 6 is located at one end of the inner wall of the center hole of the oval ring chuck 1, which is a plurality of inclined holes arranged in a circular array. The inner wall of the inclined hole is plugged with a silicone joint cap 7, and a center trigger block 8 is fixed at one end of the silicone joint cap 7. A reset spring 9 is fixed at one end of the center trigger block 8. One end of the reset spring 9 Fixed to the inner wall of the center through groove 6, an annular groove 10 connected to the center through groove 6 is opened on the opposite side of the oval ring chuck 1, a stripping ring 11 is inserted into the inner wall of the annular groove 10, a supporting spring 12 is fixed between the side of the stripping ring 11 close to the center trigger block 8 and the inner wall of the center through groove 6, a propulsion assembly is provided on the inner wall of the bottom annular groove of the center through groove 6, further, the propulsion assembly includes a propulsion ring 17 inserted into the inner wall of the bottom annular groove of the center through groove 6, and the raised end of the propulsion ring 17 fits tightly against the inclined surface of the center trigger block 8.

[0026] A further advantage of adopting the above method is that the trigger rod 14 can squeeze the central trigger block 8 from the inside of the central through groove 6 through the propulsion ring 17 connected to the reversing propulsion plate 19, and the silicone bonding cap 7 can increase the friction with the surface of the organ, so as to facilitate clamping the object to be removed from the organ. The end of the central trigger block 8 connected to the reset spring 9 is provided with a groove, which allows the propulsion ring 17 to penetrate the central trigger block 8 to push the stripping ring 11 out from the inner wall of the annular groove 10 and cut off the object to be cut.

[0027] The bottom side of the propulsion assembly is connected to the trigger assembly through the final drive assembly. Furthermore, the final drive assembly includes a serpentine groove 18 opened on the inner wall of the oval ring chuck 1, and the two ends of the serpentine groove 18 are respectively connected to the trigger groove 2 and the center through groove 6. A reversing propulsion plate 19 is inserted into the inner wall of the serpentine groove 18, and the top end of the reversing propulsion plate 19 is fixedly connected to the lower surface of the trigger rod 14, and one end of the reversing propulsion plate 19 is tightly fitted to the surface of the propulsion ring 17.

[0028] A further benefit of adopting the above method is that the serpentine groove 18 can make the movement trajectories of the two ends of the reversing propulsion plate 19 opposite to each other, and the ring angle of the serpentine groove 18 can drive the other end of the reversing propulsion plate 19 to contact or move away from the propulsion ring 17.

[0029] The present invention is used as Figure 1 As shown, the staff member presses the ring end of the clamping handle 13 with his fingers to drive the two oval ring-shaped clamps 1 to clamp the organ. When the oval ring-shaped clamps 1 continue to squeeze the organ, the two trigger rods 14 can be driven to contact and drive the Figure 2 The lifting trigger ring 5 shown in the figure moves upward, squeezing and compressing the arc plate 4 to protrude from the inner part of the outer ring through groove 3. At this time, one end of the arc plate 4 can be assembled into a small-aperture circular ring to change the apertures of the upper and lower ends of the oval ring clamp 1, thereby preventing the organ from quickly slipping out from between the oval ring clamp 1, increasing the doctor's reaction time, and clamping the organ when it slips out; At the same time, when the two trigger rods 14 are in contact, Figure 2 The upward movement of one end of the trigger rod 14 can drive the propulsion ring 17 connected to the reversing propulsion plate 19 to move downward, thereby pushing the central trigger block 8 out from the inner wall of the central through groove 6, so that the silicone joint cap 7 contacts the organ surface to increase friction; When you need to remove an object on the surface of an organ, continue squeezing according to the above actions. Figure 1 The clamping handle 13 shown in the figure causes the trigger rod 14 to be continuously compressed as shown in the figure. Figure 2 The push ring 17 shown in the figure can make the two sets of silicone joint caps 7 clamp the object to be cut, and the raised end of the push ring 17 passes through the central trigger block 8 to squeeze as shown in the figure. Figure 3 The stripping ring 11 shown is used to push the cut object out from the inside of the annular groove 10, so that the staff can take out the stripped object.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
