A micro spike having a three-dimensional structure made of single crystalline silicon and being capable of picking an enough amount of a tissue to examine the tissue while minimizing an examinee's pain with a minimal invasion when picking the tissue and a method of manufacturing the same are disclosed. The micro spike comprising: a main body part; extension parts inserted into a tissue when picking the tissue sample and integratedly extended from upper and lower parts of one side of the main body part; and a protrusion part integratedly protruded from at least one of side surfaces of the extension parts and inserted into the tissue to pick the tissue sample together with the extension parts when picking the living tissue sample.

Three-dimensional micro spike and method of manufacturing the same

Disclosed are a barb-wired single crystalline silicon micro needle and a biopsy method and a medicine injecting method using the same. The micro needle comprises a main body part, at least one extension part formed on a side surface of the main body part, and a protrusion part protruded from both side surfaces of the extension part. A medicine storage is formed on a surface of the main body part. A fluid passage is formed in the extension part and the main body part. It is easy to pick the tissue sample with the protrusion part just by inserting and extracting the extension part of the micro needle into and from the tissue for a biopsy. Therefore, the biopsy procedures can be simplified. In addition, the medicine in the storage can be injected into the tissue via the fluid passage.
