Abstract: An insertion part of an endoscope and an insertion part of a treatment tool, which are inserted in an outer tube, can be synchronously moved in the axial direction, and, even when the insertion part of the treatment tool is slightly moved in the axial direction, an excellent endoscopic image without shake is obtained. When a treatment tool of an endoscopic surgery device moves by a displacement amount over an allowance amount, an endoscope moves in interlock with the movement of the treatment tool. Moreover, the treatment tool 50 moves in the axial direction with the allowance amount t with respect to the endoscope 10. Therefore, when the treatment tool is moved by a displacement amount of allowance amount or less, the endoscope does not move. By providing such allowance amount, slight movement of the treatment tool is not transmitted to the endoscope.

Abstract: The invention provides an endoscope system for generating an oxygen saturation image that can be used for various medical applications, such as oxygen saturation monitoring during surgery. A clip 141 is attached to the surrounding tissue of a tumor CN from the luminal side. The tissue to which the clip 141 is attached becomes an ischemic part CL. An oxygen saturation image is generated from image information obtained by imaging the tissue on the abdominal cavity side. In the oxygen saturation image, the ischemic part CL is displayed as a low oxygen region. Accordingly, it becomes easy to find the location of the tumor CN even from the abdominal cavity side.

Abstract: A propulsion assembly for an endoscope includes a support sleeve and an endless track device. A clamping sleeve is contained in the support sleeve. Male and female threads cooperate for moving the clamping sleeve between operative and non-operative states upon rotation of the clamping sleeve. The operative state is on a side of a proximal direction from the non-operative state along a central axis. A sealing device is contained in the support sleeve, has a C-shape in a resiliently deformable manner, is disposed around the endoscope and between the clamping sleeve and a receiving surface. The sealing device is pushed by the clamping sleeve when the clamping sleeve is in the operative state, for squeezing the endoscope by radially compressing thereabout, and released from push of the clamping sleeve when the clamping sleeve is in the non-operative state, for releasing the endoscope by radially returning to expand thereabout.

Abstract: Provided are an endoscopic surgical device and a guide device that can satisfy the function of interlocking two medical instruments with each other. An overtube, which is punctured into a body wall and guides an endoscope and a treatment tool into a body cavity, includes an interlocking member that interlocks the forward and backward movements of the endoscope and the treatment tool with each other. The interlocking member is constituted of a first sleeve coupled to the endoscope, a second sleeve coupled to the treatment tool, and a corded flexible coupling member that couples the first sleeve and the second sleeve together. Accordingly, when the coupling member is in a relaxed state, the endoscope and the treatment tool independently move forward and backward, and when the coupling member is in a tensioned state, the endoscope and the treatment tool move forward and backward in an interlocking manner.

Abstract: A surgical device, an outer tube, an endoscope, and a treatment tool that have a simple configuration and excellent operability are provided. The outer tube includes a slider in an outer tube body. When the endoscope and the treatment tool are inserted into the outer tube, the endoscope and treatment tool are held by an endoscope holding part and a treatment tool holding part each being provided in the slider so as to be integrated. When the treatment tool is moved in the axial direction, the endoscope is moved in the axial direction in interlock with the movement. In the outer tube, the opening type hermetic valve part for the endoscope in a valve member has the inner diameter larger than the inner diameter of the elastic member for causing the endoscope holding part to hold the endoscope.
