Abstract
In the biopsy system according to one embodiment, the needle tube of the treatment tool has the minor axis of the flattened portion and the bending plane of the bending portion parallel to each other. Accordingly, the needle tube is easily bent in the bending direction of the bending portion, and even in an endoscope that has few bendable directions and is bendable, for example, in only two directions (e.g., up and down), the bending operation of the bending portion is not easily hindered. As a result, even after the treatment tool for endoscopes is inserted into the endoscope, the bending portion can be easily bent with a predetermined bending amount, and a procedure can be easily performed.
Claims8
A biopsy system comprising:
- an endoscope which includes an insertion section having a bending portion capable of being bent along a predetermined bending plane depending on an operation of an operation section;
- and
- a treatment tool for endoscopes that has a needle tube, is configured to be inserted through the endoscope, and is capable of being fixed to the endoscope by a fixing unit in a state after the treatment tool is inserted into the endoscope;
- wherein a portion of a distal end side of the needle tube includes a flattened portion having a major axis and a minor axis, and
- wherein the treatment tool for endoscopes is configured to be fixed by the fixing unit so that the minor axis of the flattened portion of the needle tube becomes parallel to the bending plane in the state after the treatment tool is inserted through the endoscope;
- wherein the needle tube has:
- a first non-flattened portion located distally relative to the flattened portion;
- and
- a second non-flattened portion located proximally relative to the flattened portion.
