Title Insertion device and endoscope
Abstract (US8944995)
An insertion device and an endoscope which are inserted and extracted through a small incision and have multiple functions.
A device body has grip forceps as a treatment means.
A first folding back section and a second folding back section are provided at a distal portion of the device body such that the first and second folding back sections are aligned in a row in the longitudinal direction of the device body.
The first folding back section and the second folding back section respectively have image obtaining means.
An operation means can move the first folding back section to a folded back position in which the first folding back section is folded back relative to the second folding back section, and can also move the second folding back section to a position in which the second folding back section is folded back relative to the device body.
Scope of claims [claim1]
1. An insertion device comprising: an elongated device body having at least one of various means including an observation means, a diagnosis means and a treatment means;
a folding back section having at least one of the various means and provided at a distal portion of the device body in such a manner that the folding back section can be folded back to a proximal side of the device body; and
an operation means provided in such a manner that the operation means can move the folding back section to a serially located position in which the folding back section is aligned with the distal portion of the device body and to a folded back position in which the folding back section is folded back to the proximal side of the device body; wherein
when the folding back section is moved to the folded back position by the operation means, the means of the device body functions in a distal direction of the device body, and the means of the folding back section functions in the distal or a proximal direction of the device body, wherein
a plurality of the folding back sections are provided, each folding back section having at least one of the various means and being provided to be aligned in the longitudinal direction of the device body in such a manner that each folding back section can be folded back relative to an adjacent folding back section on the proximal side of the device body or to the device body;
the operation means is provided in such a manner that the operation means can move each folding back section (i) to a serially located position in which each folding back section is aligned with the adjacent folding back section on the proximal side of the device body or with the device body, and (ii) to a folded back position in which each folding back section is folded back relative to the adjacent folding back section on the proximal side of the device body or to the device body;
the device body and each of the folding back sections are aligned in a row in the longitudinal direction of the device body when each of the folding back sections is in the serially located position; and
when each folding back section is moved to the folded back position by the operation means, the means of the device body functions in the distal direction of the device body, and the means of each folding back section functions in the distal or proximal direction of the device body; and
when the plurality of the folding back sections are moved to the folded back position, the plurality of the folding back sections are axially aligned around a circumference of the device body.
[claim2]
2. The insertion device according to claim 1, wherein among the folding back sections, two of the folding back sections have an image obtaining means.
[claim3]
3. The insertion device according to claim 2, wherein each folding back section comprises a first folding back section disposed at the tip and a second folding back section disposed between the first folding back section and the device body; and
the operation means is configured to include a first wire rod having one end fixed to a tip portion of a lateral surface of the first folding back section, a second wire rod having one end fixed to the lateral surface of the first folding back section or the second folding back section, and a third wire rod passing inside the first folding back section, the second folding back section and the device body and having one end fixed to the inside of the first folding back section; and configured to move the first folding back section to the folded back position by pulling the first wire rod to the proximal direction of the device body; move the second folding back section to the folded back position by pulling the second wire rod to the proximal direction of the device body; and move the first folding back section and the second folding back section to the serially located positions by pulling the third wire rod to the proximal direction of the device body.
[claim4]
4. The insertion device according to claim 3, wherein the tip portion of the device body is configured to be bendable.
[claim5]
5. The insertion device according to claim 2, wherein the tip portion of the device body is configured to be bendable.
[claim6]
6. The insertion device according to claim 1, wherein each folding back section comprises a first folding back section disposed at the tip and a second folding back section disposed between the first folding back section and the device body; and
the operation means is configured to include a first wire rod having one end fixed to a tip portion of a lateral surface of the first folding back section, a second wire rod having one end fixed to the lateral surface of the first folding back section or the second folding back section, and a third wire rod passing inside the first folding back section, the second folding back section and the device body and having one end fixed to the inside of the first folding back section; and configured to move the first folding back section to the folded back position by pulling the first wire rod to the proximal direction of the device body; move the second folding back section to the folded back position by pulling the second wire rod to the proximal direction of the device body; and move the first folding back section and the second folding back section to the serially located positions by pulling the third wire rod to the proximal direction of the device body.
[claim7]
7. The insertion device according to claim 6, wherein the tip portion of the device body is configured to be bendable.
[claim8]
8. The insertion device according to claim 1, wherein the tip portion of the device body is configured to be bendable.
[claim9]
9. An endoscope, wherein the insertion device according to claim 1 is attached to a forceps hole.
[claim10]
10. An endoscope, wherein the insertion device according to claim 2 is attached to a forceps hole.
[claim11]
11. An endoscope, wherein the insertion device according to claim 6 is attached to a forceps hole.
[claim12]
12. An endoscope, wherein the insertion device according to claim 8 is attached to a forceps hole.
[claim13]
13. An endoscope, wherein the insertion device according to claim 3 is attached to a forceps hole.
[claim14]
14. An endoscope, wherein the insertion device according to claim 5 is attached to a forceps hole.
[claim15]
15. An endoscope, wherein the insertion device according to claim 7 is attached to a forceps hole.
[claim16]
16. An endoscope, wherein the insertion device according to claim 4 is attached to a forceps hole.
