Blood vessel detection device
First Claim
1. A blood-vessel detection device for detecting the presence or absence of blood vessels underneath the tissue surface, the blood-vessel detection device comprising:
- a partially-deforming device having a cylindrical shape or a rod shape which is disposed or disposable onto the tip of an endoscope insertable into the body cavity so as to be in contact with the tissue surface in order to deform a part of the tissue surface, thereby generating turbulence in blood passing through blood vessels extending underneath the tissue surface;
a converting device for converting turbulent sound due to the turbulence generated in a part of the tissue surface deformed by the partially-deforming device into electric signals; and
a signal processing device for performing signal processing including at least amplification for the electric signals,wherein the partially-deforming device includes one of a resecting device for resecting the tissue which is to be resected, a binding device for binding a part of the tissue using a rope, and a suctioning device formed of a generally cylindrical cup.

Abstract
A blood-vessel detecting device includes a partially-deforming device which can be inserted into the body cavity so as to come into contact with the tissue surface in order to deform a part of the tissue surface so that turbulence is generated in a blood flow within blood vessels extending underneath the tissue surface, thereby enabling detection of the presence or absence of blood vessels underneath the tissue surface. Turbulent sound due to the turbulence generated at a part of the tissue surface deformed by the partially-deforming device is converted into electric signals by a converting device, following which the electric signals are subjected to signal processing such as amplification and so forth by a signal processing device.
