A thread guide device is provided which is adapted to be removably or fixedly mounted on the distal end of an endoscope, or which is an integral part thereof. Alternatively, the device may comprise a head joined to the distal end of an elongate example in the form of longitudinally extending passages, which are laterally spaced from one another. The device permits a knot formed by threads which have passed through the thread guides to be viewed by the endoscope.

A thread guide device is provided which is adapted to be removably or fixedly mounted on the distal end of an endoscope, or which is an integral part thereof. Alternatively, the device may comprise a head joined to the distal end of an elongate shaft that is slidable within the endoscope. The device has a pair of thread guides, for example in the form of longitudinally extending passages, which are laterally spaced from one another. The device permits a knot formed by threads which have passed through the thread guides to be viewed by the endoscope.

A handle is provided for attachment to a medical endoscope for advancing instrumentalities through the instrument channel of the endoscope. The handle is adapted for use with instrumentalities requiring multiple longitudinal strokes to be performed in a predetermined sequence. A detent mechanism is provided to assure that a first stroke is completed before the next succeeding stroke begins. The invention as disclosed is used to operate an endoscopic sewing machine.
