Furthermore, methods of manufacture thereof are disclosed.

Provided is an ultrasound endoscope capable of achieving both improvement of the kink resistance of a forceps tube in a bending part and improvement of electromagnetic wave shieldability in a distal end hard part.

A forceps tube is configured such that a metal element wire is wound around a tube bending part that is disposed inside a bending part, and a tube distal end part including an opening portion facing region facing an opening portion of a shield ring is formed of a material that is hardly influenced by electromagnetic waves. The tube distal end part is configured of only the forceps tube. That is, the metal element wire that is influenced by electromagnetic waves is not wound around the tube distal end part, and resin, such as fluororubber or silicon rubber, to be hardly influenced by electromagnetic waves is exposed from the opening portion facing region.

There is provided herein a flexible electronic circuit board for a tip section of a multi-camera endoscope, the circuit board comprising a front camera surface configured to carry a forward looking camera, a first side camera surface configured to carry a first side looking camera, a second side camera surface configured to carry a second side looking camera, one or more front illuminator surfaces a configured to carry one or more front illuminators to essentially illuminate the FOV of the forward looking camera, one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the first side looking camera and one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the second side looking camera.

A method for cleaning an endoscope during a surgical procedure performed with a surgical instrument. The method includes: measuring with a processor module an aggregate activation time of the surgical instrument during the surgical procedure; and activating an endoscope cleaning system with the processor module to clean a lens of the surgical instrument after the processor module determines that the measured aggregate activation time of the surgical instrument has reached a target duration.

The present embodiments provide systems and methods suitable for delivering an agent including a plurality of particles to a target site. In example embodiments, a system suitable for delivering an agent to a target site includes a catheter having a first wall defining a lumen sized for delivery of the agent to the target site. The catheter has a distal end terminating with a primary opening of the lumen, an opposing proximal end, and a longitudinal axis extending between the distal end and the proximal end. At least one secondary opening is formed at the distal end, wherein the secondary opening is configured to allow fluid to flow through the secondary opening to create a steady flow of fluid at an angle with respect to the longitudinal axis and prevent the plurality of particles from flowing through the secondary opening.

The present invention provides an improved visual laryngeal mask comprising a tube, an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. An imaging cavity extends longitudinally inside an inner wall of the tube. The imaging cavity has a built-in imaging device, and the imaging cavity protrudes forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device. A front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess.

The invention relates to an endoscope including an endoscope head, a wide-angle lens on the distal end of the endoscope head, and a working channel extending in the endoscope head. Proximally from the wide-angle lens, the working channel is bent laterally toward the outer circumference of the endoscope head, wherein a distal working channel opening is formed on a lateral side of the endoscope head.

There is provided a colon cleaning device comprising: a tube through which liquid and fecal matter are removed from a colon of a patient, the tube having a longitudinal axis; a cleaning head positioned at the distal end of the tube, the cleaning head having at least one opening coaxial with the longitudinal axis, the at least one opening sized for fecal matter to enter the interior of the cleaning head from the colon; at least one disassembly element disposed within the cleaning head; and an actuating mechanism which actuates the disassembly element to perform sweeping displacement inside the cleaning head so that the at least one disassembly element rotates around the longitudinal axis to slice through the fecal matter; wherein the cleaning head and the tube are sized and shaped to be displaced along the colon of a patient.

There is provided herein a flexible electronic circuit board for a tip section of a multi-camera endoscope, the circuit board comprising a front camera surface configured to carry a forward looking camera, a first side camera surface configured to carry a first side looking camera, a second side camera surface configured to carry a second side looking camera, one or more front illuminator surfaces a configured to carry one or more front illuminators to essentially illuminate the FOV of the forward looking camera, one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the first side looking camera and one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the second side looking camera.

An endoscope is provided to examine internal organs with front and rear views. The endoscope comprises a shaft extending from a distal end in a rearward direction along a longitudinal axis towards a proximal end, with the distal and proximal ends defining a hollow channel extended there-through. The endoscope further comprises a first lens positioned adjacent to the distal end and configured to receive a first image in a forward direction along the longitudinal axis, with the forward direction generally 180 degree from the rearward direction. The endoscope further comprises a rearview module positioned adjacent to the distal end. The rearview module comprises a second lens configured to be positioned adjacent to the distal end, and receive a second image in a target direction having a directional component in the rearward direction along the longitudinal axis, independently of the first lens receiving the first image in the forward direction.
