An actively bendable sheath such as ureteral access sheath (UAS) and a method for delivering a medical instrument (e.g. a ureteroscope) therethrough are disclosed. The sheath's tubular wall includes a deflectable or bendable segment at or adjacent to the distal sheath end. Two pull/control wires are slidably disposed within two separate dedicated channels/lumens and attached to points distally beyond the deflectable segment. The bendable segment may be passively bended by force from a bending medical instrument within it or by the force of a surgeon pulling one of the two pull/control wires.

Actively bendable sheath for delivering medical instrument therethrough and method thereof

The present invention discloses a flexible digital ureteroscope that is at least partially disposable. The ureteroscope comprises a single-use catheter and a handle. The catheter comprises a distal end, a bend portion, and a proximal portion. The distal end has a rigid or semi-rigid shell that houses a set of micro lenses, an image sensor microchip, and a plurality of LED light sources. A working channel extends along the entire catheter and is coupled to a working channel port on the handle to receive various medical devices and irrigation lines during an endoscopic procedure. In addition, the catheter includes one or more steering wires to control the distal end to bend towards a desired direction. The rigid or semi-rigid shell of the distal end is made of a mix of polymer composite material with graphene nano-filler for enhancing thermal dissipation. The handle may be a single-use handle or a reusable handle. In case the handle is a reusable handle, it includes a battery module and a wireless communication module for communicating with a host machine wirelessly. In case the handle is a single-use handle, to reduce cost, the handle does not include a battery module and/or a wireless communication module. Rather, the single-use handle includes a host interface for receiving power from the host machine and transmits image data to the host machine.

This present invention proposes new methods of designing single-use endoscopes with built-in optical fibers and operating fixtures. As compared to conventional endoscopes, a separate lumen is reserved for integrating a laser fiber along the insertion tube of the proposed endoscope, and an optical fiber placement device (OFPD) is correspondingly added in the endoscope handle for controlling the movement of the laser fiber. By sliding the slider or dialing the wheel of OFPD, a surgeon can conveniently control movement of the laser fiber. By pressing a retractable control stick in the OFPD, the surgeon can either push the laser fiber out from the endoscope's distal-end or pull back the laser fiber, further unlocking or locking the power switch of the laser fiber to avoid mis-operations. All these above operations can be performed by the surgeon's one-hand, including the routine deflections and rotations of the endoscope. Four implementations of the OFPD are introduced in this invention. In addition, an ultra-small optical fiber based pressure sensor can be added at the distal end of the endoscope upon applications.

The present invention provides a device that can move inside a biological conduit such as an intestinal tract for sampling the content therein, and a process thereof. While moving along the intestinal tract, the device can continuously collect the content in the intestinal tract. One or more convoy belts having an adsorbent layer are configured to continuously absorb and preserve the collected intestinal content. The belt loaded with the sample may be used to establish a chemical, biochemical and microbiological spectrum along the length of the intestinal tract.

Sampling device capable of continuously sampling content in a biological conduit and method thereof

The present invention provides a vehicle comprising a power source such as a primary battery, a secondary battery, and a supercapacitor. The power source includes a plurality of components. At least one of the plurality of components serves as at least a portion of the structural part of the vehicle. The power source is integrated with the structure of the vehicle, and improves the endurance of the vehicle.

Vehicle comprising a bifunctional structural part

The present invention provides a container, a transportation system comprising such a container, and a method of using the transportation system. The container includes a battery that provides electricity to a vehicle such as an unmanned aerial vehicle that is carrying and shipping the container. The battery functions as a supplemental power supply to the vehicle and hence improves the endurance of the vehicle, so that heavier cargo can be shipped over longer distance.

Container comprising a battery, transportation system comprising the same and method thereof

The present invention provides an optoelectronic module and an imaging apparatus such as an endoscope comprising such module. The optoelectronic module includes a housing and an image sensor. The image sensor's face has a perimeter S, the cross section of the optoelectronic module along the face has a perimeter H, and S&#x3c;H&#x3c;1.6S. In an example, illumination components such as a flashing LED and the image sensor are confined within the minimum bounding circle of the sensor's face. The invention exhibits technical advantage in minimizing the size of the insert portion of the endoscopy.
