Abstract:
A delivery sleeve is especially suited for surgery applications and has an elongated delivery sleeve (402). The delivery sleeve (402) comprises a hub (406) having a body portion (403) with a first channel (409) and a second channel (411). First and second channels (409, 411) are receiving proximal ends (417, 419/) of delivery sleeve (402).
Abstract:
A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. The inner cannula includes a hinge between a body section and a cutting section that allows the cutting section to pivot when the inner cannula reciprocates within the outer cannula. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A fluid supply sleeve is disposed about the outer cannula and is selectively positionable along the length of the outer cannula.
Abstract:
A cystourethroscope for prostate biopsy of the invention includes: an insertion portion that is insertable into a subject and that is bent at a predetermined curvature in a state under no external force; a grasping portion that includes a center axis in a straight line shape and that is connected to intersect with the insertion portion such that the center axis is positioned in a distal end cross section of the insertion portion; a distal end portion stretching in a convex direction of the bending from the distal end cross section; an observation portion formed on the distal end portion; and a treatment instrument insertion channel that is formed inside the insertion portion and that opens such that an inserted treatment instrument protrudes in an observation range of the observation portion.
Abstract:
This device for cutting off and removing calcified tissue from a heart valve, comprises a tubular body (1) suitable for being inserted by minimally invasive or endoscopic channel in relation with a previously inserted wire guide (g) suitable for passing through the flaps of the valve above the part where the calcified tissue needs to be removed, one of the ends of said body (1), viewed at said flaps, having a profiled end piece (2) made from flexible material and arrangements (1a) for a lateral projection of a cutting member (3) for cutting said tissue, the end of the body (1) having, upstream from the arrangements (1a) for the lateral projection of the cutting member (3), a laterally offset rounded area (1b) delimiting, on the same side as the arrangement (1a), a hollow portion (1b1), and on the opposite side, a projecting portion (1b2) suitable for bearing on the flaps during the cutting operation under the effect of a rotational movement of the body (1) that can be actuated by a single hand from a handle (4) located on the outside in order to decalcify the whole valve, said arrangement (1a) being in communication with means (6) for sucking up the cut-off tissue.
Abstract:
A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.
Abstract:
A surgical treatment apparatus according to the present invention includes an outer sheath, extending from a base portion subject to an operator's hand to the tip subject to insertion into a body cavity, that is provided with a working channel through which a treatment instrument can be passed; an image pickup device disposed at the tip portion of the outer sheath; and pivotable forceps disposed at the tip portion of the outer sheath, supported on a supporting section protruding in the axial direction via a joint being bent away from the working channel, and having a pair of forceps members arranged so as to be freely opened/closed, wherein the image pickup device is disposed at a position between the axis line of the supporting section and the axis line of the working channel and offset from an imaginary line connecting the two axis lines.
