Abstract: An intrapleural pressure regulating device that regulates the pressure in the intrapleural cavity and an operating method therefor are provided. The intrapleural pressure regulating device provides for removal of the foreign substances in the alveolar system and for supporting or replacing the functions of lungs and heart. With the intrapleural pressure regulating device, developed are a device regulating the pressure in the intrapleural cavity by pumping a fluid into the intrapleural cavity and withdrawing it from the intrapleural cavity, and an operating method for variable regulation of the pressure in the intrapleural cavity with said device.

Abstract: Provided is a wire stretcher, which is an apparatus which compresses the portion of the k-wire getting out behind the squeezing apparatus, the k-wire being passed through the wire retainer fitted on the bone surface, by rotating the holding part subsequent to being passed through the wire stretcher, thanks to the k-wire channel therein, and which enables, by rotating the outer body, the inner body with which the compressed k-wire is connected and the mid body to advance together in direction X, thereby stretching the k-wire.
