A system for modularly assembling a scope device includes an optical module which has an optical housing and a longitudinal member extending distally therefrom. A distal end of the member includes a camera for visualizing a target area, electric wires and a light source extending from the camera to the optical housing. The system also includes a deflector module coupleable with the optical module. The deflector module includes a deflector housing and a deflector shaft extending distally therefrom. The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

A piston is inserted into a piston passage of a cylinder. The piston is displaced between a first position of a non-contact state and a second position by a pressing operation. At the first position, a suction source connection port of the cylinder faces a circumferential groove of the piston and a suction source conduit communicates with an outside atmosphere. At the second position, the suction source connection port faces an outer peripheral surface opening and the suction source conduit communicates with a suction connection port. A V-shaped opening portion as a correction opening portion is formed in the outer peripheral surface opening. The V-shaped opening portion causes an increment of a communication opening width at which the suction source connection port overlaps with the outer peripheral surface opening to be three times or less an increment of a pressing stroke of the piston.

A medical device that includes a first body including a first actuation wire having a first connector that extends outwardly from the first body, and a second body including a second actuation wire having a second connector that is disposed within the second body. The first connector is configured to engage the second connector in response to the second body mating with the first body, and to deform the second connector in response to the first body disengaging the second body.

An adapter for endoscopy can operably connect camera features and light source features of a portable electronic device with a respective viewfinder and illumination element of a medical endoscope. Systems including an endoscope, adapter, and handheld electronic device with a microphone, light source, and camera can, when connected, be used to perform stroboscopic endoscopic examinations.

A hybrid apparatus for delivery of fluid in connection with endoscopic irrigation and lens cleaning including a connector which is adaptable to a flexible or rigid container, a connector arranged at the end thereof and connected via a tubing supply to a fluid, air and or gas source and to an endoscope during a procedure.

An assist device which is applied to a treatment instrument including an insertion body to be inserted through a channel of an endoscope, and which is configured to assist movement of the insertion body relative to the channel, includes: a flexible tube including a passage into which the insertion body of the treatment instrument is inserted; a connector provided on the flexible tube and configured to connect to the endoscope to allow communication between the channel and the passage; a first retainer provided on the flexible tube and configured to hold an outer circumference of an insertion section of the endoscope or an outer circumference of an operation section connected to the insertion section; and a second retainer being movable relative to the first retainer and configured to hold the insertion body of the treatment instrument.

An ocular device for a surgical instrument, the surgical instrument having an optical window frame and an optical assembly arranged in an interior space of the surgical instrument, the ocular device including: an ocular window separated from the optical assembly by a space; a holder configured to be connected to the ocular window frame; and at least one elastic element, wherein in a connected state, the at least one elastic element transmits a clamping force from the holder to bias the ocular window towards the space.

An ultrasound endoscope includes: an insertion portion configured to be inserted into a living body; an ultrasound transmitting and receiving unit; a balloon surrounding the ultrasound transmitting and receiving unit; a water supply port for supplying water to the balloon; an operating unit provided at a proximal end side of the insertion portion; a cable extending from the operating unit; a channel provided in the insertion portion and leading to the water supply port to supply water toward the water supply port; a pipe provided in the cable; a cylinder provided at the operating unit, one end of the channel and one end of the pipe being opened to the cylinder; an injection port provided in the pipe; and a duct having one end leading to the pipe via the injection port and having the other end to which a syringe for injecting water or supplying air is attachable.

A coupling mechanism includes a base and a lever. The base is configured to couple to an external fixture. The lever is pivotably coupled to the base and transitionable between a clamped configuration and an unclamped configuration. A first pair of opposed arms extends from the base and a second pair of opposed arms extends from the lever in opposed relation to the first pair of opposed arms. In the clamped configuration the second pair of opposed arms are proximate the first pair of opposed arms, and in the unclamped configuration the second pair of opposed arms are spaced apart from the first pair of opposed arms. At least one of the first pair of opposed arms or the second pair of opposed arms includes a step thereon. The step is configured to receive and retain a surgical tool therein in the clamped configuration.

An endoscopic surgical device having a slotted clear cannula, a blade and a housing, wherein the cannula is attached to the housing, and wherein the blade is enclosed in the housing and is slidable into the cannula is disclosed. The blade is enclosed within the housing and cannula, and has a horizontally-oriented pushing component and a vertically-oriented cutting component that protrudes through the slot of the cannula. The device further has a device for locking a viewing device in place relative to other components of the device. A method for a performing an operative procedure on a target tissue in a subject using the endoscopic surgical device is also described.
