采样装置

Abstract

本申请提供一种采样装置，采样装置包括：壳体，壳体具有相对设置的采样端和操作端；采样刀头，采样刀头安装于采样端，用于切割人体的体毛，以获取对应的毛囊组织；刀头驱动机构，刀头驱动机构用于驱动采样刀头，以使采样刀头旋转且外露于采样端；其中，刀头驱动机构包括操作按钮、传动组件和刀架，操作按钮安装于操作端，传动组件和刀架均安装于壳体的内部。通过采样刀头割取毛囊组织后，可以配合研磨设备的旋转研磨，将毛囊组织的细胞都磨碎，和液体混合变成悬浊液，形成自体毛囊的营养液，本身既是既有细胞外泌体，又有大量的活性的细胞器，方便后续将悬浊液抽出来，打到毛囊里去诱导毛囊再生。

Claims

1. A sampling device, characterized in that, The sampling device includes: A housing having a sampling end and an operating end disposed opposite to each other; A sampling blade is installed on the sampling end and is used to cut human body hair to obtain the corresponding hair follicle tissue. The sampling blade has a hollow structure, and the hair follicle tissue can detach from the sampling blade under the action of the air pressure difference inside and outside the sampling blade. A cutting head driving mechanism is used to drive the sampling cutting head to rotate and expose the sampling end; The blade drive mechanism includes an operation button, a transmission assembly, and a blade holder. The operation button is installed on the operation end, and the transmission assembly and the blade holder are both installed inside the housing. The operation button can be pressed, and the operation button transmits the pressing power to the blade holder through the transmission assembly, so that the blade holder drives the sampling blade to rotate and be exposed at the sampling end.

2. The sampling device of claim 1, wherein, The transmission assembly includes: A helical drive component, comprising a helical drive part and a mating part, wherein the helical drive part is configured as a helical blade, and the mating part is mated with the operation button; The rotating body includes a first connecting part and a second connecting part. The first connecting part has a receiving groove that matches the helical blade. The second connecting part is connected to the tool holder. The helical blade can enter the receiving groove during its movement in a first direction, thereby driving the rotating body to move in the first direction and rotate along its own axis.

3. The sampling device of claim 2, wherein, The second connecting part is provided with a guide elongated hole, and the sampling cutter head is provided with a guide rod, which can be inserted into the guide elongated hole.

4. The sampling device of claim 3, wherein, The tool holder is cylindrical and sleeved on the outer periphery of the second connecting part, and a spiral first limiting groove is provided on the outer side of the tool holder; The sampling device also includes a knob located inside the housing. The knob is cylindrical and fitted around the outer periphery of the blade holder. The inner wall of the knob has a first protrusion that can slide within the first limiting groove to adjust the height of the sampling blade exposed at the sampling end.

5. The sampling device of claim 4, wherein, The outer wall of the knob is provided with a second protrusion, and the housing is provided with a second limiting groove that matches the second protrusion; while the second protrusion slides in the second limiting groove, it drives the first protrusion to slide in the first limiting groove.

6. The sampling device according to any one of claims 2 to 5, wherein The transmission assembly also includes an elastic element sleeved on the outer periphery of the helical drive component, one end of which abuts against the operation button and the other end of which abuts against the rotating body; When the external force applied to the operation button is released, the spiral drive can move in a direction opposite to the first direction under the elastic force of the elastic member, thereby causing the sampling blade to retract into the housing.

7. The sampling device of claim 6, wherein, The operation button has a first toothed portion, and the mating portion of the helical drive has a second toothed portion, the shapes of the first toothed portion and the second toothed portion being matched.

8. The sampling device of claim 1, wherein, The shell has symmetrically distributed recesses on both sides.

9. The sampling device of claim 8, wherein, The distance between the recess and the operation button is within the range for one-handed operation.

10. The sampling device of claim 2, wherein, The sampling device also includes a grinding mechanism, which can be coupled to the sampling end of the housing to collect and grind hair follicle tissue. The grinding mechanism includes: A bottom cover is connected to the sampling end of the housing, and the bottom cover is provided with an injection port for injecting physiological saline. A grinding tool holder, wherein the grinding tool holder is mated with the rotating body; A grinding blade, which is fixedly mounted on the grinding blade handle; A filter screen is fixedly installed on the grinding blade handle, and the filter screen is used to filter hair follicle tissue after being ground by the grinding blade.
