In a level conversion circuit mounted in an integrated circuit device using a plurality of high- and low-voltage power supplies, the input to the differential inputs are provided. In a level-down circuit, MOS transistors that are not supplied with 3.3 V between the gate and drain and between the gate and source use a thin oxide layer. In a level-up circuit, a logic operation function is provided.

The medical treatment endoscope according to the present invention includes a sheath having a flexibility; at least one arm member having a bending part that projects out from a front end of the sheath and performs bending actions; an open/close mechanism which directs the arm member from a direction along a central axis of the sheath to a direction deviated from the central axis of the sheath, and from a direction deviated from the central axis of the sheath to a direction along the central axis of the sheath; and a viewing device and an illuminating member that are disposed to the front end side of the sheath.
摘要:
In a bipolar cutter for a living body tissue, a groove part is formed in a member that is arranged close to an active electrode, thereby providing a constitution to cut while the blood stanching is ensured since when a heat amount generated by the active electrode is conducted in the member, an excessive heat conduction to the member is efficiently interrupted by a layer of air that is produced due to the groove part and the living tissue is thus provided with more heat.
摘要:
A surgical instrument comprises: a treatment unit provided at one end of the insertion unit, capable of turning about one axis, and comprising a clamping section capable of opening and closing action; an operation unit provided at the other end of the insertion unit; a turn force transmission mechanism and transmitting a turn force as a force to turn the treatment unit; an opening and closing force transmission mechanism and transmitting an opening and closing force as a force to open and close the clamping section; and a common operation mechanism, provided in the operation unit, which can generate the turn force transmitted by the turn force transmission mechanism and which can also generate the opening and closing force transmitted by the opening and closing transmission mechanism.
