Three-dimensional micro spike and method of manufacturing the same

摘要

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.

1. A micro spike comprising:
a main body part capable of being mounted on a medical device and configured for insertion into a patient body along with said medical device for sampling a tissue sample from an organ in the patient body; at least four extension parts configured for insertion into the tissue of the organ in the patient body for sampling the tissue sample and are integrally extended toward the direction of the patient body in which the main body part is inserted, and are extensions on the upper, lower, left and right parts of one side of the main body part; and protrusion parts integrally protruded from side surfaces of the extension parts which are opposite to each other and configured for insertion into the tissue to sample the tissue sample together with the extension parts for sampling the tissue sample; wherein the width between said extension parts (t) is narrower than the width of said main body part (x), wherein the protrusion parts are not formed on the outer side surfaces of the extension part on the left-most part and the extension part on the right-most part, and are inclined toward an opposite direction from a direction spiking the patient body so that an angle between the protrusion part and the extension part is an acute angle, wherein at least one of the protrusion parts are formed on the side surfaces of each extension part to face each other.
