The present invention relates to an ergonomic bidirectional self-locking mechanism for endoscope angulation control knob operation, which allows for easier access to the endoscope control knobs, reduced muscle exertion for knob operation, and real-time locking of the position of the knobs when turned, as disclosed herein. The invention has benefits for the operator thereof from ergonomic and patient safety perspectives.

An endoscope treatment tool includes a sheath, a knife, a connecting unit and a body. The sheath includes a first channel opened at a distal end of the sheath. The knife inserted into the first channel, the knife having a second channel extending from a distal end of the knife to a proximal end of the knife. The connecting unit is located inside the sheath, the connecting unit including a cavity internal to the connecting unit and defining a storage path. A cross-sectional area of the cavity is larger than a cross-sectional area of the second channel. The body disposed in the cavity. The body is translatable in the cavity between a first position and a second position. The body forms a passage and, in the first position, the passage is in communication with the second channel.

A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.

A surgical apparatus includes a housing, a test port retainer, a pressure test chamber, and an image capture assembly. The housing includes a pressure test port. The test port retainer includes a test port retainer housing, a probe seal, and a liquid exclusion barrier. In one aspect, the test port retainer also includes a hydrophobic membrane mounted within the test port retainer housing. The pressure test chamber includes a manifold and a central tube. The first end of the central tube is affixed to the image capture assembly to form a pressure seal, and the second end of the central tube is coupled to the test port retainer so that the pressure test port communicates with the interior volume of the central tube through the test port retainer.

A method of molding a polymeric device having an elongated tube and a spiral fin. The method including: injecting a liquid resin into a mold space defining the polymeric device, the mold space having an elongated hollow tube molding space and a spiral fin molding space wound around the elongated hollow tube molding space; and providing a longitudinal flow path in at least a portion of a longitudinal length of the elongated tube molding space, the longitudinal flow path defining a concavity greater in depth than other portions of the elongated hollow tube molding space such that the liquid resin injected into the mold space flows in the longitudinal flow path to fill one or more ends of the hollow tube molding space.

A device that includes a body, a wire locking feature, and a channel. The body has an opening through which a wire is configured to extend. The channel is defined by an upper wire guiding portion and a lower wire guiding portion. The channel is configured to guide the wire between the opening and the wire locking feature. The upper wire guiding portion includes a protrusion. The wire is configured to slip past the protrusion during insertion of the wire into the channel.

The present invention discloses an auxiliary visible light rod for multisource end-expiratory CO.sub.2 monitoring. The auxiliary visible light rod comprises a handle, a pump body, a medicine compartment, a rod body and a bracket. The handle is separately connected with the medicine compartment, the pump body and the rod body, and one end of the rod body is connected with a rod head. A lamp and an atomizing head are arranged in the rod head. A circuit tube is connected with the external wall of the rod body, one end of the circuit tube is connected with a display screen, and the other end of the circuit tube is connected with a camera in the rod head. The bracket sleeves the rod body and is fixed to the outer side of an oral cavity or a chin of a patient, and thus the stability of the rod body is improved.

A method and apparatus for improving a heat dissipation capacity. An apparatus comprises an elongate member, a housing, and a heat pump device. The elongate member has a distal end and a proximal end. The housing is coupled to the proximal end of the elongate member. The heat pump device is coupled between the elongate member and the housing. The heat pump device is configured to transfer thermal energy between the elongate member and the housing.

A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.

An endoscope includes: an elevator configured to swing such that an instrument provided in an insertion portion of the endoscope changes a protruding direction; a shaft member configured to rotate about an axis, the elevator being provided on an end portion of the shaft member on one side in an axial direction that extends along the axis, the shaft member supporting the elevator on one side in the axis direction, and the shaft member being configured to be capable of rotating integrally with the elevator about the axis; a drive member that is fixed to an intermediate portion of the shaft member in the direction along the axis, and is configured to input, to the shaft member, rotation force for rotation of the shaft member about the axis; and a first bearing and a second bearing that support the shaft member so as to be capable of rotating.
