発明の名称 (英語) PRESSURE SENSOR, ENDOSCOPE HOOD, ENDOSCOPE, AND PRESSURE MEASUREMENT DEVICE
発明の概要(英語) To provide a medical endoscope which allows a physician to easily notice a change in body internal gas pressure during surgery. A pressure sensor (10) for detecting the pressure of a gas supplied to an internal body part being operated on is provided within the image field of vision of a camera in a medical endoscope, and the pressure sensor (10) converts a gas pressure inside a body to five sense information. Specifically, a circular-shaped hood (5) is attached to a distal end portion of a lens barrel (2), and the pressure sensor (10) is attached to the inner wall surface of the hood (5). The pressure sensor (10) can convert the gas pressure inside the body into colors, and, due to these colors entering the image field of vision, a physician can intuitively judge a pressure change within the operating field of vision on a monitor. Due thereto, even if the physician is concentrating on operating, it is easy to monitor pressure changes. Further, since wiring for the pressure sensor (10) is unnecessary, the external diameter of an electronic scope can be made smaller.
従来技術、競合技術の概要(英語) BACKGROUND ART
Is used in an endoscope surgery, body (as used herein, 'inside' the concept that is, the body lumen, body cavity, lumen referred to as a human body present in the organ comprises, further treatments and created in the cavity) of the air or carbon dioxide gas or air gas made by inflating the cavity, widening the field of the endoscope and the surgical operation to create the work space. However, the air within the gas pressure becomes too high, the patient may feel pain, bleeding and when severe laceration may occur.
Therefore, the gas so as not to over-air, the lens barrel of the endoscope tip is attached to the micro-pressure sensor, a gas pressure of the work in the physician can be recognized on the monitor at all times an attempt has been developed (for example, Patent Document 1) respectively. However, requires that the patient during the physician in order to concentrate, the detection signal from the pressure sensor be difficult to find.
In addition, the conventional technique of Patent Document 1 detection signal of the pressure sensor is transmitted to the monitor via electrical wiring is configured, the electrical wiring of the electronic endoscope must be passed through the inside of a scope, in this case the electronic scope is difficult to reduce the outer diameter of the, when the nasal and oral time to reduce the pain and difficult to achieve. Further, from the pressure sensor information transmitted via the electrical wiring, since the forceps port through the electrical wiring such as a surgical instrument through a forceps cannot be disadvantageously limited to surgery has occurred.
