[0035] The working process of the rotating assembly is as follows:

[0036] The lever 14 is moved, and the lever 14 drives the third connecting rod 13 to rotate with the third pin shaft 17 as the axis. When the third connecting rod 13 rotates, the second pin shaft 16 is driven to slide in the slide groove 13a. The second pin shaft 16 is fixedly connected to the second connecting rod 12. When the second pin shaft 16 slides in the slide groove 13a, it drives the second connecting rod 12 to rotate with the first pin shaft 15 as the axis. When the second connecting rod 12 rotates, the first connecting rod 11 at one end is driven to rotate. During the rotation of the first connecting rod 11, the second connecting rod 12 rotates. The horizontal displacement drives the inner sleeve rod 2 to slide in the outer sleeve 3. When the inner sleeve rod 2 slides, the shielding sleeve 1 is driven to slide through the connecting block 4. When the shielding sleeve 1 slides, the thrust spring 1a is compressed and the disposable medical gauze 7 is exposed. After the lever 14 is released, the thrust spring 1a begins to reset due to its own elastic deformation when there is no external force, and pushes the shielding sleeve 1 to be inserted into the disposable medical gauze 7. At the same time, the inner sleeve rod 2 is reset, and the first connecting rod 11, the second connecting rod 12, the third connecting rod 13 and the lever 14 are reset at the same time.

[0037] like Figure 4 and Figure 6As shown, the negative pressure suction assembly includes a suction head 18, a suction tube 19, a three-way joint 20, a negative pressure suction ball 21 and a liquid storage tank 22; the inner sleeve rod 2 is provided with a suction tube groove 2a in the radial direction, and the suction tube groove 2a penetrates the inner sleeve rod 2 along the length direction of the inner sleeve rod 2; the suction head 18 is arranged in the outer sleeve 3 near the silicone plug 23, one end of the suction tube 19 is connected to the suction head 18, the suction tube 19 is movably arranged in the suction tube groove 2a, and one end of the three-way joint 20 is connected to the side of the outer sleeve 3.

[0038] The surfaces of the shielding sleeve 1, the thrust spring 1a, the inner sleeve rod 2 and the outer sleeve 3 are all dark grey to prevent interference with the laparoscope probe when taking images.

[0039] A rubber ring 24 is provided at one end of the inner sleeve rod 2 close to the shielding sleeve 1 , and the rubber ring 24 is slidably matched with the inner wall of the outer sleeve 3 to prevent blood flowing into the outer sleeve 3 from penetrating into the joint surface of the inner sleeve rod 2 and the outer sleeve 3 .

[0040] The use process of this embodiment is as follows: when performing laparoscopic surgery on a patient, the medical staff inserts the laparoscopic probe into the surgical site of the patient, and then inserts the device into the surgical site of the patient. The medical staff holds the handle 9 and puts a finger on the lever 14. When it is necessary to stop bleeding for the patient, the lever 14 is pushed. The lever 14 drives the third connecting rod 13 to rotate with the third pin shaft 17 as the axis. When the third connecting rod 13 rotates, it drives the second pin shaft 16 to slide in the slide groove 13a. The second pin shaft 16 is fixedly connected to the second connecting rod 12. When the second pin shaft 16 slides in the slide groove 13a, it drives the second connecting rod 12 to rotate with the first pin shaft 15 as the axis. When the second connecting rod 12 rotates, it drives the first connecting rod 11 at one end to rotate. During the rotation of the first connecting rod 11, the second connecting rod 12 rotates and then moves horizontally, thereby driving the inner sleeve 2 to slide in the outer sleeve 3. When the inner sleeve 2 slides, it drives the shielding sleeve 1 to slide through the connecting block 4. When the shielding sleeve 1 slides, it compresses the thrust spring 1a and exposes the disposable medical gauze 7.

[0041] When it is not necessary to stop bleeding for the patient, release the lever 14. Due to its own elastic deformation, the thrust spring 1a begins to reset when there is no external force, and pushes the shielding sleeve 1 to insert the disposable medical gauze 7. At the same time, the inner sleeve rod 2 is reset, and the first connecting rod 11, the second connecting rod 12, the third connecting rod 13 and the lever 14 are reset at the same time; in the process of inserting the disposable medical gauze 7, the shielding sleeve 1 gradually squeezes the disposable medical gauze 7, so that the blood absorbed on the disposable medical gauze 7 flows into the outer sleeve 3 through the flow hole 5b and the liquid inlet hole 3c. The medical staff can squeeze the negative pressure suction ball 21, and release the negative pressure suction ball 21 after it is shrunk, so that negative pressure can be generated in the straw 19, so that the suction head 18 absorbs the blood flowing into the outer sleeve 3, and pumps the absorbed blood to the liquid storage tank 22.

[0042] The above embodiments are only for illustrating the technical idea of ​​the present invention, and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
