Medical support apparatus and operation method of medical support apparatus

A gas supply system appropriate for an abdominal cavity and a luminal cavity is provided. The gas supply system reduces a pressure of gas, supplied from a source of gas for supplying gas of a predetermined kind, to a predetermined pressure value upon which gas, whose pressure is reduced, is controllably lowered to a first pressure value appropriate for a body cavity of a first kind of a specimen to allow gas to be supplied to the body cavity of the first kind. In the meantime, gas, supplied from the source of gas, is lowered to a second pressure value appropriate for a body cavity of a second kind of the specimen to allow gas to be supplied to the body cavity of the second kind.

System and method for supplying predetermined gas at two different pressure values

In a gas supply system, a controller is electrically connected to a pressure regulator and an operation switch. The controller is operative to control the pressure regulator so that a predetermined gas is supplied to a first delivery member directing to a first body cavity with its pressure regulated to a first pressure suitable for the first body cavity. The controller is operative to control the pressure regulator depending on an instruction sent from the operation switch upon operation of the operator so that the predetermined gas is supplied to a second delivery member directing to a second body cavity with its pressure regulated to a second pressure suitable for the second body cavity.

Method and system for supplying predetermined gas into body cavities of a specimen

An endoscopic system includes an endoscope having a delivery member available to supply a body cavity of a specimen and, in addition thereto, a gas supply apparatus from which predetermined gas is supplied to a body cavity via a delivery member. The endoscopic system further includes a determination unit that determines whether or not there is a status in which, the gas supply device needs to supply gas to the body cavity, and a control unit that selectively and automatically control a permit and stop for the gas supply to be implemented by the gas supply apparatus depending on a determined result of the determination unit, which are formed in a unitary structure with, for instance, the gas supply unit.

Endoscopic system equipped with gas supply apparatus

A gas supply source for supplying gas and a channel along which the gas is supplied can be easily switched by providing an instrument channel for passing an endoscope treating tool, a gas and water supply channel for supplying carbon dioxide etc. to the inside of a body, a gas supply source for a visceral cavity capable of supplying gas at a predetermined pressure, a gas supply source for a lumen capable of supplying gas at an optional pressure, and a switch device for switching from any of and an instrument channel and a gas and water supply channel to any of the gas supply source for a visceral cavity and the gas supply source for a lumen.

Endoscope apparatus

In order to control the pressure in an abdominal cavity of a patient and a pressure in a hollow organ, a medical system includes: a first pressure sensor for measuring the pressure of a gas in the abdominal cavity; a first port for insufflating and evacuating the abdominal cavity; a second pressure sensor for measuring the pressure of a gas in the hollow organ; a second port for insufflating and evacuating the hollow organ; an air supply apparatus connected to the second port for controlling the air supply and evacuation based on the output by the first and second pressure sensors; a third port connected to the second pressure sensor in the air supply apparatus; an endoscope connected to the air supply apparatus; a pneumoperitoneum needle connected to the first port; and a puncture needle connected to the second port.

In a treating apparatus, a forceps body as a treating device is connected to a generator as a control device. The forceps body mainly includes a pair of handle portions, which are used for manipulation by being held by an operator, a pair of jaws provided between the handle portion and the pair of jaws, which are used to coagulate/resect by grasping living-body tissue to be treated and a pair of scissors component members. A heating member, which is a heat generating source as a heat generating portion for applying heat energy to living-body tissue, is embedded at least one of the jaws. A pair of electrode portions, which is a treating energy generator, is provided to the pair of jaws. By supplying bipolar electric surgical knife current between the pair of electrode portions, high frequency current as treating energy is applied to the grasped living-body tissue.

Semiconductor device and a manufacturing process therefor

A plurality of p wells and a plurality of n wells are formed in a p-type semiconductor substrate having a memory portion and a peripheral circuit portion. Next, a resist pattern is formed on the semiconductor substrate. The resist pattern has apertures which, as viewed from the direction normal to the plane of the semiconductor substrate, approximately coincide with the p wells, wherein the area of aperture openings on the top side of the resist pattern is different from the area of aperture openings on the bottom side of the resist pattern. By using the resist pattern as a mask, p-type ions are injected in a shape approximately the same as that of the aperture opening on the top side or bottom side, whichever has the smaller area. Thereafter, by using the same resist pattern as a mask, n-type ions having enough energy to pass through resist of a predetermined thickness are injected into the p-type semiconductor substrate through areas, located adjacent the apertures in the resist pattern, in which the effective thickness of the resist is small, thereby forming deep n wells so as to cover the p well regions.
