A medical apparatus is provided which includes a usage detecting section which operates in connection with an operation of a medical device. A counting section stores a value corresponding to a number of operations of the usage detecting section.
摘要:
A plurality of pieces of medical equipment each of which includes a microcomputer and has a program used to control the microcomputer stored in a reproqrammable storage device such as an EEPROM is linked to a remote computer over a communication line. Using a rewriting/updating program sent from the computer, each piece of medical equipment rewrites or updates the program stored in the storage device. When a plurality of programs is stored, if one of the programs is rewritten or updated abnormally, the other program is used to activate medical equipment.

According to the present invention, a high-frequency treatment apparatus includes: an electrode assembly electrically connected to the high-frequency generating unit for generating a high-frequency current, the assembly having at the distal end thereof a current-applying electrode for discharging the high-frequency current, the proximal end of the current-applying electrode being covered with a first insulating member; an insertion section receiving the electrode assembly such that the electrode assembly is movable in predetermined directions, the insertion section being located on the return side of the high-frequency current applied from the current-applying electrode; a liquid supply unit for supplying an irrigation liquid to the vicinity of the current-applying electrode; and a second insulating member for covering a predetermined area on the surface of base part of the current-applying electrode, the base part being exposed from the distal end of the first insulating member.
摘要:
A shaft of a laparoscopic instrument, having a ceramic tube which extends over the main length of the shaft and has a sheath which encloses the ceramic tube in at least some regions, is situated to cover those regions of the ceramic tube that are at risk of breakage and is designed to prevent the splinters of ceramic from penetrating through the sheath. The ceramic tube forms a predetermined breaking point in the region of the sheath.

摘要:
A surgical instrument has a first grasping member, a second grasping member which is provided to the first grasping member to open and close to the first grasping member, and grasps a living tissue between them, an ultrasonic coagulation-cutting unit which includes an ultrasonic vibrating portion provided in one of the first and second grasping members and connected to an ultrasonic transducer to generate ultrasonic vibration, and a pressing portion provided in the other of the first and second grasping members, and facing the ultrasonic vibrating portion, the pressing portion and the ultrasonic vibrating portion pressing the living tissue between them, and a high-frequency coagulation unit which includes a first electrode provided in the first grasping member, and a second electrode provided in the second grasping member, the first electrode and the second electrodes facing each other to coagulate the living tissue.
摘要:
The surgical instrument comprises: an insertion portion; a treatment unit which is provided on the tip portion of the insertion portion and which is capable of turning as to the shaft of the insertion portion and capable of opening and closing; an operating unit provided at the base portion of the insertion portion and which is capable of turning as to the shaft of the insertion portion and capable of opening and closing; a supporting member linking the treatment unit and the operating unit; and a plurality of driving rods arrayed in parallel or generally in parallel with the supporting member, so as to be capable of advancing and retreating; wherein the opening/closing operating mechanism of the treatment unit and the opening/closing operating mechanism of the operating unit are in a parallel mapping relation following the insertion portion.
摘要:
A phenol resin-impregnated sheet formed by impregnating a porous resin sheet with a phenol resin having a degree of cure of from 70% to 95% is arranged on and lamininated to the surface of a carbon fiber-reinforced thermosetting resin sheet. The thickness of the phenol resin impregnated sheet is between 0.01 mm and 1.0 mm. A very even, strong and water-proof wood reinforcing material is obtained. The wood reinforcing material is intergrated and cured on the surface of the wood material by the phenol resin-impregnated sheet to reinforce wood material (single board or bonded board) to form a reinforced wood material. The wood reinforcing material adheres suitably with the wood material and does not cause environmental contamination.
