摘要： A system for inserting a cannulated tissue anchor during endoscopic or other surgical procedures. The system incorporates an insertion instrument for inserting into a surgical site of implantation an elongated generally cylindrical tissue anchor having, for example, a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The anchor may be inserted by a single-handed operation of the instrument through a series of sequential pulls of a trigger, each pull affecting motion of a particular element. In a preferred embodiment, three trigger pulls are sufficient to penetrate the site of implantation and deliver the anchor slidably along the needle. The instrument operates with replaceable subassemblies each containing a particular size cannulated anchor, having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle.

摘要： An elongated, rotatable surgical cutting instrument having a rotatable cutting element at the distal end of a bendable non-rotating elongated outer member. The instrument enables operation of various cutting devices such as a bendable rotatable burr. In one embodiment the cutting element is rotatably, but irremovably attached to the distal end of the outer member. The proximal end of the cutting element is then releasably attached to the distal end of a flexible coupling which in turn is attached to the distal end of an elongated inner member. The assembly is then rotatably secured within the outer member so the cutting element may be rotated via the inner member. An aspirating lumen extends through the cutting element, the flexible coupling and the inner member and the inner member may be removed from the outer member without detaching the cutting element therefrom. In another embodiment, the cutting element is removable from the outer member when the inner member is removed.

摘要： A centrifugal chuck for a surgical handpiece is adapted to automatically engage a surgical instrument so it may be driven by the handpiece. The centrifugal chuck comprises a pivotable trunnion body situated within a hollow drive shaft, the trunnion body having a throughbore coaxially aligned with the axis of the hollow drive shaft in order to receive the shaft of the surgical instrument. The trunnion body is secured to a pair of lever arms symmetrically situated about the exterior of the drive shaft, the lever arms extending in opposite proximal and distal directions from the pivotable attachment of the trunnion body to the drive shaft. Rotation of the drive shaft causes radially outward movement of the lever arms thereby misaligning the throughbore of the trunnion body relative to the drive shaft in order to frictionally engage the shaft of the surgical instrument. A spring member integrally formed with each lever arm maintains a predetermined bias on the trunnion body in order to provide a predetermined minimum amount of friction to enable the instrument shaft to be retained within the handpiece at speeds below those at which the centrifugal forces become operative. The invention also resides in the method of attaching a surgical instrument to a handpiece utilizing a centrifugal clutch.

摘要： A bioabsorbable soft tissue anchor system comprising a cannulated soft tissue anchor for being turned through soft tissue, and a driver for driving the anchor and method for attaching soft tissue at a selected site of implantation. The soft tissue anchor is an elongated unitary body having a threaded distal section, a non-threaded proximal section, a transverse proximal head and a non-circular axial throughbore. The threaded section has a cancellous-type thread which has a uniform minor diameter, a large pitch and a large major diameter, the distal end of the thread being tapered toward the distal end of the anchor. The proximal end of the threaded section abuts the non-threaded section which is tapered and extends proximally to the transverse head. The anchor is used with a driver having a driving shaft with a pointed tip and a cross-section adapted to engage the anchor's axial throughbore. The driving shaft is longer than the anchor so that the anchor may be placed on the shaft leaving the tip exposed to permit tissue to be pierced and placed adjacent a pre-formed hole at the site of implantation. Simultaneous pushing and turning of the driver will then advance the anchor through the tissue and into the pre-formed hole.

摘要： A wrenchless collet for attaching a surgical saw blade to an oscillating handpiece. The collet is provided within a housing attached to the handpiece and contains a clamping means for holding the blade and a bi-stable operating mechanism capable of holding the clamping means in either an open position to receive the blade or in a closed position to hold the blade for use with the handpiece. The bi-stable operating mechanism is activated into either position by simply being pushed in one direction or another. In one embodiment, the bi-stable operating mechanism comprises a shaft which may be positioned to one axial extreme or the other and which is held in the chosen position by a spring which frictionally engages the collet housing to maintain the clamping means in either an open or closed position.

摘要： A pneumatically powered surgical handpiece suitable for a pencil-type handpiece configuration in which the pressurized fluid inlet is axially directed relative to the handpiece body. Fluid is directed through a dispersing section from an axial direction to a radially outward direction against the interior of a hollow cylindrical turbine body provided with a plurality of circumferentially arranged and longitudinally extending semi-circular channels adapted to receive the fluid flow and redirect it proximally through an annular exhaust channel situated annularly about the fluid inflow conduit. An output shaft is integrally formed with the turbine body and extending distally therefrom and a surgical instrument may be attached to or integrally formed within this output shaft. The invention also resides in a method for fluidically driving a surgical handpiece and lends itself to a method of producing a disposable fluidically driven surgical instrument.

摘要： A suturing needle is illustrated which can engage a suture to an outer housing, thereby presenting a relatively smooth surface at the distal end of the apparatus to minimize tissue trauma. A lock feature prevents unexpected extension of the needle from the outer housing which could release the suture. A finger switch is used to overcome the locking mechanism when it is desired to release the suture. The distal end of the housing and the needle are a generally similar flat profile to minimize uneven edges which could damage the tissue. The suture is retained in a hook located in the needle, the opening for which is retracted in the housing to retain the suture.
