Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a tumor extraction device for neurosurgery. Background Art

[0002] Neurosurgery is a department that treats diseases of the brain, spinal cord and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, brain trauma caused by a car accident, or brain tumor compression requiring surgical treatment. During surgical operations, hospitals generally use vascular clamps to clamp and lift the tumor to remove the tumor during surgery. When clamping with vascular clamps, it takes up a lot of space and is prone to tissue damage. At the same time, due to the delicate nerve tissue, it is difficult to clamp with vascular clamps during neurosurgery, so a negative pressure extraction device is generally used.

[0019] 1. By starting the negative pressure pump, negative pressure is generated in the extraction component. The suction tube is aligned with the tumor. The solid tumor squeezes the elastic body to deform the elastic body, and the spring is compressed. Then the solid tumor is sucked into the solid holding tube together with the liquid. The blocking tube effectively prevents the tumor from falling out of the suction tube. The solid tumor is sucked to the bottom of the fixed box.

When performing neurosurgery, there is no need to frequently transfer the absorbed tumor, and there is no need to worry about the absorbed tumor falling during the absorption process. The operation is convenient;

[0020] 2. By providing a protective component, the negative pressure connecting tube can be protected from being contaminated. The second waterproof breathable membrane effectively blocks moisture from entering the protective tube. The desiccant inside the drying tube absorbs very little moisture in the protective tube. The third filter blocks the desiccant and solid to prevent them from entering the negative pressure connecting tube, so that the negative pressure connecting tube can be reused. The first stab fixes the absorbed solid tumor material, and the second stab effectively prevents the absorbed solid tumor material from escaping from the absorption tube. After the tumor material extraction is completed, the first fixed tube is separated from the second fixed tube, so that the absorbed fixed tumor material in the solid holding tube can be easily taken out. When the tumor material is absorbed, due to the suction force, the tumor material squeezes the elastic body, causing the elastic body to become deflated, and then the tumor material reaches the solid holding tube. When the suction force disappears, due to the presence of the elastic body, the solid tumor material will not fall out of the absorption tube. The extraction component places the extracted tumor material on the placement tray, and then covers the sealing cover. The ice bag cools the tumor material. The extracted tumor material can be collected and transported by the collection component for easy testing. BRIEF DESCRIPTION OF THE DRAWINGS

The first spur 30 fixes the sucked solid tumor material, and the second spur 31 effectively prevents the sucked solid tumor material from escaping from the suction tube 16.

[0044] like Figure 6 and Fig. 9 As shown: the solid containing tube 12 includes a first solid tube 32 and a second solid tube 33, and the first solid tube 32 and the second solid tube 33 are detachably connected by threads. After the tumor extraction is completed, the first fixed tube is separated from the second fixed tube to facilitate the removal of the fixed tumor absorbed in the solid containing tube 12.

[0045] like Figure 10-11 As shown: the cross-sectional shape of the elastic body 18 is set to be arc-shaped, and the elastic body 18 is made of medical silicone material. Three elastic bodies 18 are blocked inside the suction tube 16.

[0048] Working principle of the present invention:

[0049] Refer to the instruction manual Figure 1-11 When performing neurosurgery, the negative pressure pump 2 is started, and negative pressure is generated in the extraction component. The suction tube 16 is aimed at the tumor, and the solid tumor squeezes the elastic body 18 to deform the elastic body 18. At the same time, the spring 19 is compressed, and then the solid tumor is sucked into the solid holding tube 12 together with the liquid. The blocking tube 17 effectively prevents the tumor from falling out of the suction tube 16. The solid tumor is sucked to the bottom of the fixed box 13, and the liquid reaches the solid connecting tube 8 through the pores 15. The first filter element 10 filters the solid in the solid holding tube 12. The one-way valve 9 prevents the liquid from flowing back into the solid holding tube 12. The liquid passes through the solid connecting tube 8 and reaches the liquid holding tube 7. The first waterproof and breathable membrane 5 and the second filter element 6 in the liquid connecting tube 4 filter the solid particles and moisture again. Finally, the protective component protects the negative pressure connecting tube 3 to prevent the negative pressure connecting tube 3 from being contaminated and can be reused. After the tumor extraction is completed, the negative pressure pump 2 is turned off to obtain a solid-liquid separated tumor extract;

[0050] Refer to the instruction manual Figure 1-11 During neurosurgery, the protective component can protect the negative pressure connecting tube 3 from being contaminated. The second waterproof breathable membrane 29 effectively blocks moisture from entering the protective tube 25. The desiccant 28 in the drying tube 27 absorbs very little moisture in the protective tube 25. The third filter 26 blocks the desiccant 28 and solids to prevent them from entering the negative pressure connecting tube 3, so that the negative pressure connecting tube 3 can be reused. The first spur 30 fixes the absorbed solid tumor material, and the second spur 31 effectively prevents the absorbed solid tumor material from escaping from the suction tube 16. After the tumor material extraction is completed, By separating the first fixed tube from the second fixed tube, it is convenient to take out the fixed tumor material sucked in the solid containing tube 12. When the tumor material is sucked, due to the suction force, the tumor material squeezes the elastic body 18, causing the elastic body 18 to deflate, and then the tumor material reaches the solid containing tube 12. When the suction force disappears, due to the existence of the elastic body 18, the solid tumor material will not fall out of the suction tube 16. The extraction component places the extracted tumor material on the placement tray 21, and then covers it with a sealing cover 24. The ice bag 23 cools the tumor material. The extracted tumor material can be collected and transported by the collection component for easy testing.
