Tubed manifold of a multiple viewing elements endoscope
The specification describes a manifold for use in a tip section of a multi-viewing elements endoscope. The manifold has: a first section attached to an elongated second section, where the proximal section has a proximal socket and the distal section has a distal socket; a groove having a first portion along a first axis parallel to a longitudinal axis of the manifold, and a second portion along a second axis tilted at an angle to the first axis; and a working channel tube wherein a distal segment of the tube extends along the first axis to lie within the first portion of the groove, and where a proximal segment of the tube extends along the second axis to lie within the second portion of the groove.
1. A multi-viewing elements endoscope comprising:
a manifold positioned in a tip section of the endoscope, the manifold comprising:
a first section having a first width and a first length, and comprising a proximal socket;
a second section extending from said first section proximate said proximal socket, and having a second width and a second length, and comprising a distal socket, wherein the second width is less than the first width and the second length is greater than the first length; and
a groove extending from an entry port of the proximal socket to an entry port of the distal socket, wherein the groove is partially open and extends inward towards a central longitudinal axis of the manifold from an outer circumferential surface of the manifold;
a tube having a proximal end and a distal end and positioned in said groove, wherein said distal end is held within the distal socket and said proximal end extends out of the proximal socket; and
an electronic circuit board assembly positioned adjacent said manifold in the tip section, wherein the electronic circuit board assembly comprises a front viewing element and a first side viewing element, and wherein each of the front viewing element and the first side viewing element comprises at least one of a charge coupled device and a complementary metal oxide semiconductor image sensor.
2. The endoscope of claim 1 , wherein the tube comprises a first tube segment and a second tube segment that meet each other at a predefined angle.
3. The endoscope of claim 2 , wherein the first and the second tube segments are laser-welded, sewn, or glued together at the predefined angle.
4. The endoscope of claim 1 , wherein the tube has a circular cross-section.
5. The endoscope of claim 4 , wherein a diameter of the tube ranges from 1 millimeter to 10.5 millimeters.
6. The endoscope of claim 1 , wherein the tube is made from a medical grade material, stainless steel, brass, and/or Teflon.
7. The endoscope of claim 1 , wherein the tube is autoclavable and reusable, or disposable.
8. The endoscope of claim 1 , wherein the proximal end of the tube is connected to a channel that runs from a handle through a shaft and a bending section of the endoscope, and wherein said channel is defined by a third tube.
9. The endoscope of claim 1 , wherein the proximal end of the tube is glued, laser-welded, or sewn to the proximal socket, and wherein the distal end of the tube is glued, laser-welded, or sewn to the distal socket.
10. The endoscope of claim 1 , wherein the proximal socket is partially open at an external surface of said manifold.
11. The endoscope of claim 10 , wherein the partial opening of the groove is connected to the partial opening of the proximal socket.
