Abstract:
According to one embodiment of the present invention, an anastomosis device includes: a first jaw; a second jaw adapted to correspond with and face the first jaw such as to allow movement between opening and closing positions relative to the first jaw; at least one anastomosis member disposed on the first jaw at the initial stage; a wedge disposed at the lower portion of the anastomosis member for carrying out transitional motion along the longitudinal direction of the first jaw inside the first jaw, and having a blade for cutting a part of a tissue by the transitional motion and a slanted surface for driving the anastomosis member so that the anastomosis member passes through the tissue towards the second jaw for carrying out the anastomosis of the tissue; and a link member having a plurality of rotatable links connected to each other by connection pins and moving together with the wedge.
Abstract:
Disclosed is an optical fiber coating apparatus for preventing generation of bubble in a coating layer of an optical fiber when the optical fiber is coated, which includes a coating unit for allowing an optical fiber to pass through and forming a coating layer on the optical fiber; a base coupled with a lower portion of the coating unit to draw the optical fiber; a cover installed to an upper portion of the coating unit to isolate the coating unit from an external air and having an optical fiber introduction hole; a gas supply line for supplying gas, having smaller kinetic viscosity than the air, into an inner space formed by the cover; and a coating agent discharge line for discharging a coating agent remained in the inner space of the cover. The inner space forms positive pressure circumstance by using the gas having smaller kinetic viscosity than the air.
Abstract:
According to one embodiment of the present invention, a knee brace comprises: an upper brace positioned at a thigh region of a wearer when the knee brace is worn; a lower brace positioned at a shin region of the wearer when the knee brace is worn; and a reciprocal hinge connecting the upper brace to the lower brace such that the lower brace is rotatable with respect to the upper brace. The reciprocal hinge includes: a guide plate connected to either the upper brace or the lower brace, and having a first and a second guide hole intersecting one another and forming a preset angle; a first and a second moving body which move along the first and second guide holes, respectively; and a connecting bar, one end of which is connected to either the upper brace or the lower brace and the other end of which is rotatably coupled to the first and second moving bodies, such that the connecting bar is rotated with respect to the guide plate according to the movement of the first and second moving bodies along the first and second guide holes, respectively.
Abstract:
Disclosed is a heating element having a ring shape provided in a furnace for drawing an optical fiber from a large-diameter preform so as to heat and melt a preform. The heating element according to heating element includes at least two hot zones having different heating temperatures, wherein one of the hot zones is arranged in a neck-down region of the preform to heat the preform at a temperature suitable for drawing an optical fiber. Also, the hot zone includes a first heating unit for heating a preform at a temperature suitable for draw an optical fiber from the preform; and a second heating unit for heating a surface of the preform to a relatively lower temperature than the first heating unit.
