Title: Cryoprobe
Inventor: KURIYAMA TORU
IPC: A61B18/02
Filed: 1991-08-02
Abstract: PURPOSE:To provide a cryoprobe which has a construction of a high cooling capacity with a smaller size. CONSTITUTION:A cryoprobe has a high thermal conduction internal piping 4 arranged in a heat insulating piping construction closed airtightly with a lid body 5 which abuts a lesion at the tip thereof to cool and an orifice 8 is provided at the tip of the piping 4. A high pressure nitrogen gas supplied from a nitrogen cylinder 9 is supplied to the internal piping 4 and is JT-expanded with the orifice 8 to impinge the lid body 5 as mist flow from the orifice 8 so that the lid body 5 is cooled down to a very low temperature. The mist flow impinging the lid body 5 is turned to a low temperature and low pressure nitrogen gas and discharged outside through a passage between the internal piping 4 and a piping structural body. A high pressure gas moving toward the orifice 8 with the low temperature and low pressure nitrogen gas undergoes a heat exchange to be cooled before reaching the orifice 8. Thus, the mist flow from the orifice 8 is further cooled thereby enabling the cooling of the lid body 5 efficiently.

Filed: 1991-08-05
Abstract: PURPOSE:To reduce the length of a lead screw axis by providing a leaf spring through a movable piece on the upper side of a stopper, keeping the pressing function of the leaf spring and by placing the stopper and the leaf spring in the same place with respect to the axial direction. CONSTITUTION:A lead screw axis 1 transmits the leaf spring 13 force to an engagement piece 4 through a movable piece 12. Therefore, when the axis 1 rotates, a screw thread 1a moves along the axis direction and the engagement piece 4 and a head carriage make the same motion. Furthermore, if the device is accelerated, a force is generated in the axial direction between the carriage and the axis 1, the engagement piece 4 tends to drop out from the thread 1a, however, a stopper 11 prevents it. Having the configuration in which a portion of the carriage that engages to the axis 1 and the spring 13 be placed on top of the stopper 11 through the movable piece 12, the size of the portion, that engages to the axis, becomes small and the total length in the direction of the feed is reduced.

Abstract: PROBLEM TO BE SOLVED: To make it possible for a lifting insert to be buried in a plate block to execute lifting work with safety without exerting the action of force in the axial direction when the block is lifted up and enhance the outward view without removing any repair mark of the insert which remains on the surface of the plate. SOLUTION: According to this construction method of a plate block 1, the plate blocks 1 are arranged with joint spaces mutually. In this case, the plate blocks 1, which are provided with a lifting pin 2 forming a stopper 4 at the tip with a projection, which is not larger than the joint space, are arranged at least two locations which sandwich the center of gravity of the block are arranged on the side surface by lifting up the blocks with a lifting jig 6 which is formed thinner than the joint space and provides an engagement means where the lifting pin 2 is removable. Therefore, when the blocks are lifted up, the force in the axial direction and the force at right angles act on the lifting pin 2, which makes it possible to prevent falling out of the blocks 1 and execute construction with safety.  Since no insert is buried in the surface of the plate blocks 1, there remains no repair mark on the surface.
