The present invention relates to a linear silicone valve trocar for maintaining hermeticity by being inserted into a valve base inside a sleeve constituting a trocar used in a surgical operation, and a sleeve using the same. The linear silicone value comprises: a pair of linear ribs which have an open and close unit by being in contact with each other in a vertical direction; a slope membrane having a u-shaped surface under the rib; a variable cylinder unit which is continued at a side end and a lower end of the slope membrane and having a cylinder shape; a sealed cylinder unit having a thicker thickness than the variable cylinder unit by being stepped to an outer direction at a lower end of the variable cylinder unit; and a fixed groove unit protruding from the lower end of the sealed cylinder unit to the outside and in which an insertion groove is formed. A guide rib is protruded from the inner surface of the slope membrane to a vertical direction. A reinforced part is included on both end units, in which the linear ribs are connected, in a perpendicular direction of the linear rib. |
