摘要： An anoscope adapted for the suturing of hemorrhoids during a hemorrhoid removal procedure is disclosed. The anoscope has a distal conical tip, a channel body extending proximally from the distal conical tip and a flange radiused outwardly from the channel. A slot is formed in the channel body and runs longitudinally from the distal conical tip through the flange and is flanked by a pair of mutually opposed finger wings that extend out from the flange. The finger wings each have a distal finger wing tip and a concave surface embedded within the finger wing tips. The concave surfaces are sized for the placement of a finger of a user therein.

摘要： A circular sapling instrument for the removal of hemorrhoids has a stapling end effector having a casing, a hollow staple driver within the casing, an annular blade having an open distal end is located within the staple driver, and a elongated interior drive shaft is reciprocable within the staple driver and the annular blade. A first inner chamber is defined between the staple driver and the interior drive shaft, and a second inner chamber is defined between the annular blade and the drive shaft. The first chamber communicates with the second chamber. The casing has an exterior surface and a substantially unobstructed passageway extends within the casing surface, into the first inner chamber, into the second inner chamber, and through the open distal end of the second inner chamber for insertion and withdrawal of a surgical instrument therethrough.

摘要： A method for using a circular stapling instrument for the removal of hemorrhoids is disclosed. The circular stapling instrument has a stapling end effector having a stapling head assembly and an anvil assembly movable from an open position spaced away from the stapling head to a closed position adjacent to the stapling head. A first inner chamber and a second inner chamber communicate within the stapling head assembly wherein the second inner chamber has an open distal end when the anvil is in an open position. A substantially unobstructed passageway extends from an exterior casing surface of the stapling head assembly through the first inner chamber, through the second inner chamber, and through the open distal end of the second inner chamber. A suture is placed into the hemorrhoid of a patient and the open stapling end effector is placed into the anus of a patient. The open stapling end effector is positioned with the suture between the stapling head and the open anvil assembly and a surgical instrument is placed into the passageway to engage the suture through the open distal end of the second chamber. The suture is withdrawn out of the passageway with the surgical instrument. The suture is pulled by the surgeon to draw the hemorrhoids into the open distal end of the stapling end effector and into the first and second inner chambers. The open anvil is closed and the circular stapling instrument is fired to staple and cut the hemorrhoids. The circular stapling instrument and the hemorrhoids are then removed from the patient.

摘要： A system and method for more efficient cleaning and sterilizing of surgical handpieces by using a removable valve assembly. The valve assembly is removable to provide access to a first suction passageway and a second suction passageway for cleaning purposes. The valve assembly has a protrusion that engages with a handpiece to secure the assembly to the handpiece. The protrusion of the valve assembly may also be retracted into the valve assembly to allow the valve assembly to disengage the handpiece thereby allowing the valve assembly to be removed from the handpiece. The first suction passageway may also be removable.

摘要： An endoscopic rotary abrader allowing for increased burr size while maintaining the required minimum clearance between the burr and the hood. This is accomplished either by an offset configuration of non-concentric inner and outer tubes, where the inner tube is shifted laterally away from the hood, or by employing an enlarged hood.

摘要： Grasping an object, e.g., a calculus in the biliary tract, using a grasper, such as a basket, that can be opened and closed without mechanical advantage and also rotated about the device axis to make it easier to capture the object. The basket can then be closed further with mechanical advantage to crush the object.

摘要： A retracting two-piece cannula for distracting soft tissue from bone (e.g., the articular surface of a knee) to provide a surgical workspace for osteochondral repair. After inserting an outer cannula provided with a threaded outer surface into an incision (preferably widened by one or more dilators), the outer cannula is rotated to engage the threaded outer surface with the soft tissue to be distracted. An inner cannula is then inserted into the outer cannula and advanced until it contacts the articular surface. Further relative movement between the inner and outer cannulas causes the outer cannula to be drawn away from the articular surface, thereby retracting the soft tissue and establishing the workspace. The inner and outer cannula are then locked together to maintain the workspace, and an osteochondral core may be introduced through the inner cannula.

摘要： A high efficiency electrosurgical electrode with an advanced electrically conductive tip and advanced design tube, and a method of conducting an electrosurgical procedure with such electrode. The tube design is provided with a swaged one-piece metal tube that fits in small cannulas (as small as a 5.5 mm cannula). The electrode has a scalloped configuration that provides decreased surface area with more edges. The handle is provided with an ergonomic design that utilizes a bend with a cut at the end of the tube (for example, a 30 degree bend with a 15 degree cut).
