Abstract: The present disclosure provides a portable apparatus to maintain temperature of an object comprising a first chamber containing a quantity of a thermal material. The first chamber is thermally coupled to a container holding the object of interest. Ambient air is driven over the thermal material and then towards the container to change the temperature of the container. A valve is provided near the container which can be opened to allow entry of ambient air towards the container. Either of the heated or cooled air flow and the operation of the valve is regulated to maintain the temperature of the container to within a predetermined temperature range. The container is configured to be sealed to isolate the object from the ambient and allows for a means to preserve object quality. A housing of the apparatus is provided with a provision to protect the first container from mechanical shocks.

Abstract: The present invention provides a laparoscopic apparatus having an elongated barrel connected to a handle case with a fixed handle and a movable handle. A rotatable conduit is connected to a rotatable wheel with a movable rod disposed inside the elongated barrel, which is operable by the rotatable wheel. An end-effector with wrist-like movement is connected to an articulation assembly of the fixed handle in conjunction with a universal joint. The laparoscopic apparatus of the present invention with the end-effector assembly provides a wrist-like lateral movement. The laparoscopic surgical apparatus of the present invention has an improved articulation and an extra degree of freedom, while retaining its existing surgical functions.
