Title ADHERING BODY AND ADHESION DEVICE
Abstract The purpose of the present invention is to enable an adhering body to be easily and stably adhered to a flexible object that easily deforms. This adhering body (10) is provided with an elastically deformable body (5) that moves between a closing position (C) at which a communication hole (6b) is closed and an open position (D) at which the communication hole (6b) is open. When a movable contact part (4) is moved to a withdrawal position (B), the elastically deformable body (5) moves synchronously to open the communication hole (6b).
Outline of related art and contending technology BACKGROUND ART
To adsorb the object as, for example as disclosed in Patent Document 1 and the gripping device. Disclosed in Patent Document 1 is the gripper, the object to adsorb the body, is connected to the suction, a suction through the suction passage to the suction pump to generate an attractive force, is provided. Adsorbent is, the suction flow path has a communicating hole, and closing the communication hole is provided with a switching valve. The valve unit, has an elastic restoring force formed by a polymer material, the contact surface of the adsorbent and the object in the object side than the protruded position and having a protrusion biased. The protruding portions, and by the abutment of the object, the protruding position to the retracted position retracted from the contact surface side and is switched to. In addition, in the adsorbent contacting surfaces of the object, the valve portion of the projection part is inserted into the through-hole is provided. Patent Document 1 disclosed apparatus, the protrusion of the valve section is brought into contact with the object by pressing, the protrusion protrudes to a position retracted from the position of the switch itself. Then, due to the change, the valve through hole is opened, this open state of the communicating hole and the through hole and the communicating state. Thus, adsorption pump suction force from acting on the object through the through hole, the object is held by suction.
In addition, in Patent Document 2, the heartbeat rate used at the time of coronary artery bypass under the suction device, the disclosed stabilizer. The lower of the heart in the coronary artery bypass, the heart is beating and accordingly, it cannot be a blood vessel of the anastomosis. Stabilizer, and is limited only a portion of the movement of the heart, vascular anastomosis to facilitate instrument. Such a stabilizer, having a plurality of suction cups. And a plurality of suction cups is pressed against the surface pressure from the inside of the organ, organ surface partially immobilized by suction, is stabilized at an anastomosis site.
