A trocar including a trocar head attached to a cannula having a lumen with a distal opening, the cannula includes at least one elastomeric band positioned across said lumen.

A narrow-orifice foreign body extraction device configured as a unitary article comprises a volumetric enclosure bounded by a frustoconical cone, which has inner and outer surfaces and an intermediate section positioned between an apertured cap section and an apertured base section. The inner surface defines a boundary of an interior chamber of the volumetric enclosure, and the inner and outer surfaces define between them a cone wall. An adhesive material is secured to at least part of the inner or outer surfaces at the cap section and comprises an apertured portion and a tail portion. The apertured portion has one or more adhesive apertures and adhesive-covered opposing inner and outer side surfaces, and the tail portion has an adhesive-covered inner tail surface extending along and bonding to at least part of the outer surface at the cap section to secure the adhesive material to the cap section.

This invention relates to an endoscopic device, and more particularly but not exclusively to an endoscopic device suitable for use in diagnostic and/or surgical procedures. The endoscopic device includes a base and a shaft extending from the base. The shaft is at least partially flexible and includes a bending section that is selectively displaceable between a straight configuration and a bent configuration. The endoscopic device also includes an actuation arrangement for selectively displacing the bending section between the straight and bent positions. The actuation arrangement includes at least one actuator which is at least partially made from a shape memory alloy, and which is configured to displace the bending section of the shaft when electric current is passed therethrough. The actuator is located inside the base of the device.

Integrated hysteroscopic treatment systems which includes an endoscopic viewing system, a fluid management system, a resecting device and a controller for operating all the systems.

A multi-directionally guided endoscope includes an endoscope body. The endoscope body is connected to a catheter. At least four pulling wires are evenly distributed in the endoscope body. One ends of the pulling wires are connected to an end of the catheter away from the endoscope body. The pulling wires are respectively fixed to pulling mechanisms. The pulling mechanisms are respectively sleeved on guide rods. The guide rods are fixed in the endoscope body. The endoscope body is provided with a plurality of elongated grooves. One ends of the pulling mechanisms respectively extend from the elongated grooves. The multi-directionally guided endoscope is provided with pulling mechanisms that are simple in structure, convenient to operate, and accurate and stable to pull.

Embodiments of the present disclosure provide a disposable sheath for an endoscope device. The endoscope sheath includes an elongated conduit including a first end and a second end. The elongated conduit is configured with a plurality of hollow ports extending from a proximal portion to a distal portion of the elongated conduit. Further, the sheath includes a shield body member including a first flap member and a second flap member extending from the first end and the second end, respectively. The first flap member and the second flap member are operated between a closed position and an open position for encasing the endoscope device for performing an endoscopy. The sheath includes an endoscope cap adapted to releasably engage with a portion of the elongated conduit and the shield body member encompassing a distal end of the endoscope device.

An endoscope decontamination sheath includes a terminal section for seeing therethrough for an image and a sleeve section connected to the terminal section for receiving an endoscope to insert therein. The terminal section is of a tubular configuration. The terminal section has a front end to which a lens is mounted and a rear end in which an insertion groove is formed. The sleeve section is of an elongated tubular configuration having a front end fit into the insertion groove of the terminal section. In medical treatment of endoscopy or intubation, the endoscope is inserted into and sleeved with the sleeve section, and the endoscope sleeved with the decontamination sheath is inserted into an endotracheal tube. The matched arrangement between the lens and a lens of the endoscope helps prevent image deterioration and thus making images clearer. The decontamination sheath, after use, can be disposed of to prevent cross infection.

Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a working space expanding system positioned at a distal portion, the working space expanding system movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body lumen. A tissue retractor having an inner member positioned within an outer member has a plurality of closed loops at a distal portion forming a petal-like structure. The loops are positioned in a collapsed position within the outer member and are movable to an expanded position when exposed from the outer member.

A cleaning sheath for an endoscope includes an open ended sheath coupled to a fluid line via a hub. The sheath is configured to receive an endoscope within the interior of the sheath wherein both the sheath and the endoscope may be inserted into a trocar during use. The sheath is configured to direct a cleaning fluid onto the optics end of the endoscope to clear away any visual obstructions without requiring the removal of the endoscope from the trocar. The hub is configured to hold the endoscope in a desired position during use to allow a user to selectively adjust and fix the position of the optics end of the endoscope relative to the distal end of the sheath during use at a location extending beyond the distal end of the sheath, aligned with the distal end of the sheath, or withdrawn into the distal end of the sheath.

An endotracheal tube includes a main tubular portion including a distal end and a proximal end opposite the distal end, the main tubular portion including a central lumen at least in part defined by a wall of the main tubular portion; a wire lumen disposed within the wall of the main tubular portion, the wire lumen defined at least in part by a sidewall portion of the wire lumen and extending from about the proximal end of the main tubular portion to about the distal end of the main tubular portion; a wire disposed in the wire lumen; and one or more cutouts extending along a portion of the wall of the main tubular portion, the cutouts comprising openings in the sidewall portion of the wire lumen, wherein the cutouts are not in fluid communication with the central lumen.
