[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figure 1-4 As shown, the rocket head lymph node grabber includes:

[0028] The pliers include a head 10, a bar 20, a handle 30, a ring 40, and an end 50. The handle 30 is fixedly connected to the bar 20 via the end 50. The head 10 is rotatably connected to the distal end of the bar 20. The ring 40 is rotatably connected to the end 50. The edge of the ring 40 located inside the end 50 is fixedly connected to a lever 43, and the lever 43 is connected to the head 10 via a traction rope 44. The top of the end 50 is provided with a locking mechanism and a pressing mechanism. The pressing mechanism is correspondingly located on one side of the locking mechanism, and the locking mechanism is inclined and contacts the top of the lever 43.

[0029] One end of the ring 40 is fixedly connected to the pin 41, and the pin 41 is rotatably connected to the inside of the end head 50. The end head 50 is made of flat metal material, and a groove 56 for the ring 40 to rotate is opened inside the end head 50. A U-shaped protrusion 31 with an inclined distribution is fixedly connected to the top of the end head 50. The locking mechanism consists of a paddle 33 and a torsion spring 34. The middle part of the paddle 33 is rotatably connected to the inner wall of the end head 50, and both sides of the paddle 33 are connected to the inner wall of the end head 50 through the torsion spring 34. The top of the protrusion 31 is threadedly connected to the bolt 32. One end of the bolt 32 corresponds to the inclined paddle 33, and the other end of the paddle 33 corresponds to the lever 43.

[0030] In this technical solution, the ring 40 rotates inside the end 50 via the pin 41, which in turn drives the lever 43 to rotate. When the lever 43 pulls the traction rope 44, it pulls the clamp head 10 of the cross structure, thereby closing the clamp head 10. While gripping, the lever 43 contacts the lever 33 and moves the lever 43 past the lever 33. Due to the presence of the torsion spring 34, the lever 33 returns to its original position. At this time, the lymph node is gripped. When the ring 40 is released, the spring 42 returns to its original position, and the ring 40 rotates in the opposite direction. At this time, the lever 43 contacts the lever 33, and when the lever 33 rotates in the opposite direction, it presses against the bolt 32, restricting the rotation of the lever 33 and preventing the ring 40 from returning to its original position. This achieves a continuous gripping state, which facilitates the removal of the lymph node and prevents the lymph node from falling off due to loosening during the removal process.

[0031] Furthermore, when it is not necessary to control the self-locking after a single grab by the lever 33, simply tighten the bolt 32 to make the bolt 32 push the lever 33 to rotate, so that the bottom end of the lever 33 does not contact the lever 43 after it rotates. That is, the finger ring 40 and the lever 43 will not contact the lever 33 during the entire rotation process, thereby realizing the normal use of the lymphatic grabbing forceps. At this time, the fixation after grabbing can be achieved by the clamping mechanism.

[0032] Both the end 50 and the clamp bar 20 have through holes for the movement of the traction rope 44. The distal end of the clamp bar 20 has two symmetrically distributed clamp heads 10. The two clamp heads 10 are connected by a spring and are intersected. Both clamp heads 10 are connected to the traction rope 44. One end of the ring 40 is fixedly connected to a spring piece 42, which is in contact with the interior of the end 50.

[0033] In this technical solution, when the lever 43 rotates, the traction rope 44 can move inside the through hole. When the finger ring 40 is released, the spring 42 drives the finger ring 40 to reset, and at the same time, the spring on the pliers head 10 makes it open again, which facilitates subsequent gripping.

[0034] The clamping mechanism consists of a bushing 51, which is fixedly connected to the top end of the end 50. The surface of the bushing 51 is movably sleeved with a U-shaped collar 52, and the surface of the collar 52 is threadedly connected to a knob 55. The collar 52 and the end 50 have interconnected circular holes. A connecting rod 53 is fixedly connected inside the collar 52. The connecting rod 53 is located inside the circular hole and passes through the bushing 51 and the end 50, extending into the through hole at the traction rope 44. A pressure block 54 is fixedly connected to the bottom end of the connecting rod 53 located inside the through hole, and the pressure block 54 is located above the traction rope 44. The surface of the bushing 51 has a groove 56, which is distributed correspondingly to the knob 55, and the end of the knob 55 extends into the groove 56.

[0035] In this technical solution, when the lever 33 is not used for single locking, after the lymph node is grasped, the collar 52 is moved downwards, causing the collar 52 to drive the connecting rod 53 and the pressure block 54 to move downwards. After the pressure block 54 presses the traction rope 44, the knob 55 is tightened to achieve the limit, which facilitates locking after grasping. Even if there is loosening, it will not cause the lymph node to fall off, improving the convenience of use. When used in conjunction with the locking mechanism, it can be flexibly changed according to the use needs and usage scenarios, improving the performance of the lymph node grasping forceps.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
