Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 - Figure 4 The utility model provides a technical solution: a device for separating and recovering brain tumor tissue, comprising a main mechanism 1 and an auxiliary mechanism 2, wherein the auxiliary mechanism 2 is located above the main mechanism 1, and the main mechanism 1 comprises a device body 101 and a separation screen 102, wherein the separation screen 102 is located inside the device body 101;

[0026] The main mechanism 1 also includes an electric motor 103, a screw rod 104, a movable nut 105 and a support ring 106. The electric motor 103 is fixedly installed at the right end of the inner end of the device body 101, the screw rod 104 is fixedly installed at the transmission end of the left end of the electric motor 103, the movable nut 105 is threadedly connected to the outer end of the screw rod 104, the support ring 106 is fixedly installed at the front end of the movable nut 105, and the separation screen 102 is movably connected to the support ring 106. The electric motor 103 drives the screw rod 104 to rotate at a uniform speed. The rotation of the screw rod 104 makes the two groups of movable nuts 105 move at a uniform speed. The movable nut 105 drives the support ring 106 to move, thereby driving the separation screen 102 to move left and right, and shaking it at a uniform speed, so that the separation screen 102 has a better separation effect on brain tumor tissue. After the separation of brain tumor tissue is completed, the staff pulls the door panel to remove the separation screen 102 and collect the brain tumor tissue inside the separation screen 102.

[0027] The auxiliary mechanism 2 includes a feed hopper 201 and a protective cover 202. The feed hopper 201 is fixedly mounted on the upper end of the device body 101, and the protective cover 202 is movably mounted on the upper end of the feed hopper 201. The auxiliary mechanism 2 also includes a movable disk 203. The movable disk 203 is fixedly mounted on the left end of the inner end of the device body 101. The left end of the screw rod 104 is rotatably connected to the movable disk 203. The auxiliary mechanism 2 also includes a slider 204 and a slide rod 205. The slider 204 is fixedly mounted on the front end of the support ring 106, and the slide rod 205 is fixedly mounted inside the device body 101. The slider 204 is slidably connected to the slide rod 205. The auxiliary mechanism 2 also includes a collecting cylinder 206 and a hydraulic cylinder 207. The collecting cylinder 206 is movably mounted on the lower end inside the device body 101, and the hydraulic cylinder 207 is fixedly mounted on the left and right ends inside the device body 101. The auxiliary mechanism 2 also includes an adjusting rod 2 08 and positioning plate 209, the adjusting rod 208 is fixedly mounted on the transmission end of the inner end of the hydraulic cylinder 207, the positioning plate 209 is fixedly mounted on the inner end of the adjusting rod 208, and the collecting cylinder 206 is located at the inner end of the positioning plate 209. When the device body 101 is used to separate and recover brain tumor tissue, the staff opens the protective cover 202 and places the extracted brain tumor tissue into the feed hopper 201. The brain tumor tissue inside the feed hopper 201 enters the separation screen 102 inside the device body 101. Under the action of gravity, the tissue fluid and the dispersed tissue are separated through the separation screen 102 and fall into the collecting cylinder 206 inside the device body 101. After the separation of the brain tumor tissue is completed, the hydraulic cylinder 207 is started to separate the positioning plate 209 from the collecting cylinder 206, and the collecting cylinder 206 is taken out to collect the separated tissue and tissue fluid.

[0028] Working principle: When the device body 101 is used to separate and recover brain tumor tissue, the staff opens the protective cover 202 and places the extracted brain tumor tissue into the feed hopper 201. The brain tumor tissue in the feed hopper 201 enters the separation screen 102 inside the device body 101. Under the action of gravity, the tissue fluid and the dispersed tissue are separated through the separation screen 102 and fall into the collection cylinder 206 inside the device body 101. The electric motor 103 drives the screw rod 104 to rotate at a uniform speed. The rotation of the screw rod 104 causes the two sets of movable nuts 105 to move at a uniform speed. The movable nut 105 drives the support ring 106 to move, and the support ring 106 drives the slider 204 to move on the slide rod 205, thereby driving the separation screen 102 to move left and right, and shaking it at a uniform speed, so that the separation screen 102 has a better separation effect on the brain tumor tissue. After the brain tumor tissue is separated, the staff pulls the door panel to remove the separation screen 102, collects the brain tumor tissue inside the separation screen 102, starts the hydraulic cylinder 207 to separate the positioning plate 209 from the collection cylinder 206, and takes out the collection cylinder 206 to collect the separated tissue and tissue fluid.
