A mobile split-seat assembly having a support frame including a base, a first vertical support extending upwardly from the base and a second vertical support extending upwardly from the base. A first pivoting arm assembly includes a first seat portion and is supported by the first vertical support so that the first seat portion is pivotable in a horizontal plane relative to the support frame. A second pivoting arm assembly includes a second seat portion and is supported by the second vertical support so that the second seat portion is pivotable in a horizontal plane relative to the support frame.

Mobile split-seat assembly

A apparatus is disclosed that is adapted for delivery of a multiplicity of pre-loaded ligating bands within patient, such as to treat hemorrhoidal tissue. The apparatus comprises a delivery member that includes a tissue receiving chamber at the distal end that communicates with a passageway that represents part of the main suction pathway that connects with a suction means. The proximal portion of the apparatus includes an actuating mechanism that is operatively connected to one or more band carrier elements, such as strands with bead-like retainers, which receive and urge the ligating bands over the delivery member for deployment. The actuating mechanism and suction actuating interface are configured such that they can be controlled while the operator retains the other hand for another operation, such as to manipulate an anoscope. In one embodiment, the proximal portion includes a pistol-shaped grip portion, while the actuating mechanism comprises a knurled wheel.

Ligating band delivery apparatus

An endoscopic ligating apparatus is provided that can be used to dispense multiple ligating bands or rings about several lesions. In one embodiment, a barrel supporting a plurality of bands stretched around its circumference is removably engaged to the insertion end of an endoscope. A trip wire extends through a working channel of the endoscope and includes at least one piece of flexible material extending from the distal end of the barrel and wrapped around the end of the barrel. The ligating bands are situated over the flexible material. As tension is applied to the trip wire by way of an activating mechanism, the flexible material retracts within the barrel so as to draw the ligating bands successively to the end of the barrel.

Endoscopic ligating apparatus

An endoscopic ligating apparatus is provided that can be used to dispense multiple ligating bands or rings about several lesions. In one embodiment, a barrel supporting a plurality of bands stretched around its circumference is removably engaged to the insertion end of an endoscope. A trip wire extends through a working channel of the endoscope and includes a plurality of strands extending from the distal end of the barrel and wrapped around the end of the barrel. The ligating bands are situated over the strands, while the strands are provided with beads disposed adjacent the bands. As tension is applied to the trip wire by way of an activating mechanism, the strands retract within the barrel so that the beads draw the ligating bands successively to the end of the barrel.

An endoscopic ligating apparatus is provided that can be used percutaneuously to dispense multiple ligating bands or rings about several lesions. In one embodiment, a barrel supporting a plurality of bands stretched around its circumference is removably engaged to the insertion end of an endoscope. A trip wire extends through a working channel of the endoscope and includes a plurality of strands extending from the distal end of the barrel and wrapped around the end of the barrel. The ligating bands are situated over the strands, while the strands are provided with beads disposed adjacent the bands. As tension is applied to the trip wire by way of an activating mechanism, the strands retract within the barrel so that the beads draw the ligating bands successively to the end of the barrel. In one embodiment, the activating mechanism includes a mounting component that stably mounts the mechanism to a variety of endoscopes. The activating mechanism can be manually operated and can include a one-way clutch that can be selectively engaged to restrict the rotation of a spool upon which the trip wire is wound. In another aspect of the invention, an irrigation adapter can be supplied to provide irrigation or aspiration through the activating mechanism and working channel of the endoscope.

A flexible endoscopic instrument is provided with a plurality of elastic ligating rings mounted on one tube of a pair of tubular members which are affixed in coaxial relation to the insertion end of an endoscope. The rings are adapted to be dislodged therefrom in sequence at selectively controlled times for treating multiple lesions during a single insertion of the endoscope into a body organ. The endoscope is equipped with illumination and viewing [means] apparatus to facilitate orientation of the instrument in the body organ, and longitudinally extending tubular passages comprising a channel through which objects may be passed and suction applied for drawing the lesion tissue into the tubular end of the endoscope to facilitate ligation of a lesion, and a working channel through which a flexible actuating cable is inserted. The cable is connected to one of the tubular members and serves to [as a means for] impart[ing] relative motion between the pair of tubular members to sequentially dislodge the elastic rings from the endoscope at controlled times. Each of the elastic rings can be dislodged from the endoscope and placed in ligating relation to a lesion when lesion tissue is drawn into the innermost of the tubular members by a suction force applied through the suction channel and each of the rings can be applied to a different one of the multiple lesions in the body organ during a single insertion of the endoscope.

Endoscopic ligating instrument

An endoscopic instrument for ligating multiple lesions within a hollow body organ. A flexible endoscope 10 is provided with channels 16-21 for accomodating means for illumination, viewing and application of suction and is also provided with a hollow tubular member 101 affixed to the insertion end of the endoscope. A plurality of cords 103 are laid over the tube 101 to extend longitudinally thereon and be folded over the distal end of the tube. The cords 103 are connected to one another at a common point by a connector 106 inside the tube 101. A plurality of elastic rings 50 are mounted on the tube 101 in stretched condition and overlaying the cords 103. The segment of each cord 103 between each pair of adjacent rings 50 is in slack condition and of a length which equals or exceeds the distance of the tube's distal end to the furthest ring of the pair. By a trip cord 105 threaded through a working channel 19 of the endoscope and connected to the cords 103, a pull can be exerted thereon to simultaneously retract the cords 103 and dislodge each of the rings in controlled stepped sequence in a procedure wherein only one elastic ring at a time moves over the tube in the process of its dislodgement to ligate a lesion which has been suctioned part way into the tube 101.

An endoscopic instrument for ligating multiple lesions within a hollow body organ. A flexible endoscope 10 is provided with a pair of tubular members 25, 26 affixed to the insertion end of the endoscope and a plurality of elastic ligating rings 50 are mounted side-by-side on one of the tubular members in uniformly spaced relationship. The endoscope is provided with longitudinally extending tubular passages comprising channels 16, 17 for accommodating means for illumination and viewing, a channel 18 for applying a suction force and a working channel 19. A flexible cable or wire 55 inserted through the working channel and connected at one end to one of the tubular members is movable for imparting relative motion between the tubular members in response to which an elastic ring 50 can be dislodged from the endoscope and placed in ligating relation to a lesion when the insertion end of the endoscope is oriented in surrounding relation to a target lesion and lesion tissue drawn into one of the tubular members by suction and whereby additional elastic rings can be sequentially dislodged and additional lesions similarly ligated during a single insertion of the instrument.
