The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] First embodiment:

[0021] See also Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the clinical collection equipment for tumor samples. Figure 2 It is a schematic diagram of the structure of the sealing component. Figure 3 yes Figure 2 A magnified image of Figure 4 It is a structural schematic diagram of the limiting protrusion.

[0022] The utility model provides a clinical tumor sample collection device, including an extraction tube 101, a needle 102 and a sealing assembly 103, wherein the sealing assembly 103 includes a fixed shaft 104, a sealing plate 105, a rotating rod 106, a pull rod 107, a piston 108 and a locking member 109, wherein the rotating rod 106 has a limiting protrusion 112, the pull rod 107 has a limiting groove 113, the fixed shaft 104 includes a shaft body 114 and a limiting seat 115, and the sealing member 108 is driven by rotating the pull rod 107. The plate 105 rotates, so that the through hole 111 on the sealing plate 105 is offset from the mounting hole 110 on the extraction cylinder 101. At this time, the sealing plate 105 can seal the extraction cylinder 101 to prevent external bacteria from entering the interior of the extraction cylinder 101. It can be understood that the above-mentioned scheme can be used to seal the extraction cylinder 101 conveniently, and can also be used to solve the problem of locking the pull rod 107 to prevent the pull rod 107 from rotating during collection or sealing.

[0023] According to this specific embodiment, the needle 102 is detachably mounted on the extraction cylinder 101 . The extraction cylinder 101 is provided with a mounting hole 110 , and the needle 102 is mounted at the mounting hole 110 .

[0024] The fixed shaft 104 is fixedly connected to the extraction cylinder 101 and is located inside the extraction cylinder 101. The sealing plate 105 is rotatably connected to the fixed shaft 104 and is sleeved on the fixed shaft 104. The rotating rod 106 is fixedly connected to the sealing plate 105 and is located on one side of the sealing plate 105. The piston 108 is slidably connected to the extraction cylinder 101 and is located inside the extraction cylinder 101. The pull rod 107 is fixedly connected to the piston 108 and slides with the rotating rod 106. The locking member 109 is provided on the pull rod 107 and locks the pull rod 107. The sealing plate 105 is provided with a through hole 111, which penetrates the sealing plate 105 and cooperates with the mounting hole 110. When in use, the needle 102 is installed on the extraction cylinder 101, and the pull rod 107 is rotated to drive the rotating rod 106 to rotate, so that the rotating rod 106 drives the sealing plate 105 to rotate, thereby causing the sealing plate 105 to rotate. The through hole 111 of the extraction tube 101 is aligned with the mounting hole 110 on the extraction tube 101, and then the needle 102 is punctured to the lesion site, and the pull rod 107 is pulled to drive the piston 108 to move, so that negative pressure is formed inside the extraction tube 101, thereby sucking tumor cells into the extraction tube 101. Tumor cells can enter the extraction tube 101 through the mounting hole 110 and the through hole 111. During the extraction process, the pull rod 107 is locked by the locking member 109 to prevent the pull rod 107 from being pulled during the pulling process. Rotation occurs. After the extraction operation is completed, the locking member 109 releases the lock on the pull rod 107, and then the pull rod 107 is rotated, so that the pull rod 107 drives the rotating rod 106 to rotate, and then drives the sealing plate 105 to rotate, so that the through hole 111 and the mounting hole 110 are staggered. At this time, the extraction cylinder 101 is sealed to prevent external bacteria from entering the extraction cylinder 101. The doctor can seal the extraction cylinder 101 by rotating the pull rod 107, thereby facilitating the doctor's operation.

[0025] Secondly, the limiting protrusion 112 is arranged on the rotating rod 106 and is located on one side of the rotating rod 106; the limiting groove 113 is arranged on the pull rod 107 and is located on the side of the pull rod 107 close to the limiting protrusion 112, and the limiting groove 113 cooperates with the limiting protrusion 112. There are two limiting protrusions 112 and two limiting grooves 113 respectively, and they are respectively located on the left and right sides of the rotating rod 106. The limiting protrusion 112 is limited by the limiting groove 113, and then the rotating rod 106 is limited, so that the rotating rod 106 can only rotate with the rotation of the pull rod 107, thereby avoiding slippage between the pull rod 107 and the rotating rod 106, which affects the sealing of the extraction cylinder 101.

[0026] At the same time, the shaft body 114 is fixedly connected to the extraction cylinder 101, and is rotatably connected to the sealing plate 105, and is located inside the extraction cylinder 101; the limiting seat 115 is fixedly connected to the shaft body 114, and is located on one side of the shaft body 114, and the sealing plate 105 is limited by the limiting seat 115 to prevent the sealing plate 105 from being separated from the rotating shaft.

[0027] When using the clinical tumor sample collection device of this embodiment, the piston 108 is moved by pulling the pull rod 107, thereby forming a negative pressure inside the extraction tube 101 to achieve the purpose of collecting tumor cells. After the collection is completed, the locking member 109 is released from the pull rod 107, and then the pull rod 107 is rotated to drive the rotating rod 106 and the sealing plate 105 to rotate, so that the through hole 111 on the sealing plate 105 is staggered with the mounting hole 110 on the extraction tube 101. At this time, the sealing plate 105 can seal the extraction tube 101, thereby achieving the purpose of facilitating the doctor to seal the extraction tube 101.

[0028] Second embodiment:

[0029] Based on the first embodiment, please refer to Figure 5 , Figure 5 2 is a schematic diagram of the installation structure of the spring of the second embodiment. The locking member 109 of this embodiment includes a locking plate 201 , a spring 202 and a pressing seat 203 . The locking plate 201 has a first locking groove 204 and a second locking groove 205 .

[0030] According to the present specific embodiment, the locking plate 201 is detachably connected to the extraction cylinder 101 and is located at one side of the extraction cylinder 101; the spring 202 is connected to the pull rod 107 and is located inside the pull rod 107; the pressing seat 203 is connected to the spring 202 and is located at one end of the spring 202; the first locking groove 204 is provided on the locking plate 201 and is located at one side of the locking plate 201 close to the pressing seat 203; the locking plate 201 is detachably connected to the extraction cylinder 101 through a buckle; a plurality of springs 202 are provided and are evenly distributed on the pull rod 107, the elasticity of the spring 202 drives the pressing seat 203 to move, so that the pressing seat 203 extends into the first locking groove 204. At this time, the through hole 111 on the sealing plate 105 is aligned with the mounting hole 110 on the extraction cylinder 101, and the pressing seat 203 is limited by the first locking groove 204, and then the pull rod 107 is limited, so that the pull rod 107 can only move in the vertical direction and cannot rotate, thereby preventing the pull rod 107 from rotating during movement, causing the through hole 111 and the mounting hole 110 to be staggered, affecting the collection of tumor cells.

[0031] Among them, the second locking groove 205 is arranged on the locking plate 201 and is located on one side of the locking plate 201. When the collection is completed, the pressing seat 203 is pressed to disengage the pressing seat 203 from the first locking groove 204. At this time, the pull rod 107 can be rotated. At this time, rotating the pull rod 107 drives the rotating rod 106 and the sealing plate 105 to rotate. When the through hole 111 on the sealing plate 105 is staggered with the mounting hole 110, the pressing seat 203 is aligned with the second locking groove 205, and then the pressing seat 203 is extended into the second locking groove 205 under the action of the spring 202, thereby locking the sealing plate 105 in the sealed state to prevent the sealing plate 105 from rotating during sealing and affecting the sealing of the extraction cylinder 101.
