Abstract:
Apparatus (20, 120, 300) and methods for use in the performance of minimally invasive orthopedic procedures, including apparatus and methods for use in the performance of such procedures under the visualization of an endoscope (22), are herein disclosed. Such procedures include a minimally invasive intramedullary nailing procedure, a minimally invasive bone graft harvesting procedure, a minimally invasive pelvic osteotomy procedure, an orthopedic implant revision procedure, and a minimally invasive percutaneous bone plating procedure.
Abstract:
A method and device for endoscopic harvesting of blood vessels from a patient for use in subsequent procedures. The device having a two piece headpiece. A vessel to be removed is inserted into the headpiece and the top and bottom portions of the headpiece are alternatively extended in reciprocating fashion to dissect above and below the vessel. The headpiece having electrodes for ligation of any side branch vessels which are uncovered in the dissection process.
Abstract:
A kit for the construction of a bone plate assembly for fixation of a fractured bone is provided. The kit includes a plurality of plate members, a connecting member for retaining the plurality of plate members in a desired configuration and a plurality of locking members for securing the plate members to the connecting member.
Abstract:
An external fixator system includes a fixation bar, a fixation pin, and a clamp assembly. The clamp assembly includes a first jaw pair, a second jaw pair, and a first spring insert. The first jaw pair has a first upper jaw component and a first lower jaw component that collectively define a first passage configured to receive the fixation bar. The second jaw pair has a second upper jaw component and a second lower jaw component that collectively define a second passage configured to receive the fixation pin. The first spring insert is positioned within the first passage and interposed between the first upper jaw component and the first lower jaw component. Advancement of the fixation bar into the first passage causes deflection of the first spring insert
Abstract:
A bipolar electrosurgical instrument useful in harvesting blood vessels such as veins and arteries. The instrument has a pair of jaws and a central cutting element displaceable distally and proximally to dissect tissue contained between the jaws. The instrument has offset electrodes.
Abstract:
A surgical device including: a punch slidingly disposed in a housing for forming a hole in a first vessel; a cartridge movably disposed in the housing between a cutting and deploying positions, the cartridge having a second vessel and a coupler for coupling the first and second vessel loaded therein; a punch actuator for sliding the punch between the cutting and deploying positions; a cartridge actuator for moving the cartridge between the cutting and deploying positions, wherein while in the cutting position, the punch and cartridge are in position to permit the punch to form the hole in the first vessel and while in the deploying position, they are in position to deploy the second vessel; and a deployment mechanism for deploying the second vessel and coupler into the hole of the first vessel while the punch and cartridge are in the deploying position to create an anastomosis.
Abstract:
An instrument is provided for everting an end of a vessel over an end of a tubular workpiece, wherein a portion of the vessel is positioned within an axial bore of the tubular workpiece. The instrument comprises a conical holder comprising a first end, a second end, a longitudinal axis, and a lumen therethrough. The conical holder is positionable coaxially with the axial bore of the tubular workpiece. The lumen at the first end has a first diameter smaller than the diameter of the end of the tubular workpiece when extended distal to the end of the tubular workpiece. The first end is radially expandable so that the lumen at the first end is larger than the end of the tubular workpiece. The instrument further comprises a mandrel having a first end, a second end, and a longitudinal axis therebetween. The first end of the mandrel is insertable into the first end of the conical holder. The mandrel is tapered from a smaller diameter at said distal end to a larger diameter at said proximal end. The instrument further comprises a sleeve having an axial sleeve bore for slidably retaining the mandrel in coaxial alignment with the longitudinal axis of the conical holder. The sleeve has an annular groove for pressing against the first end of the conical holder with the vessel therebetween.
Abstract:
A surgical instrument useful in harvesting blood vessels such as veins and arteries. The instrument has a pair of jaws and a central cutting element displaceable distally and proximally to dissect tissue contained between the jaws. The distal ends of the jaws form a dissecting tip.
Abstract:
A partially tied surgical knot is disclosed. It has a proximal loop, first loop, plurality of knot loops, and a core loop received in a common loop core formed by the knot loops. The partially tied knot can be readily converted into a non-slip knot to provide enhanced suture knot security. The technique for deployment ensures the user that the conversion will be performed consistently each time, therefore providing a consistent knot security for multiple applications. Also disclosed is an assembly which features the partially tied knot in combination with a core tube to facilitate the conversion of the partially tied knot into the fully tied knot.
Abstract:
A Suture cartridge assembly is disclosed. The cartridge assembly has a partially tied surgical knot formed from a suture filament for facilitating the fastening of body tissue. It also has a core tube to which the partially tied knot is secured. Further, the assembly has a suture cartridge which contains a tube slot for receiving the core tube. The assembly makes it easier to convert the partially tied surgical knot into a non-slip knot to securely and consistently fasten tissue. It is simple in construction, and it is readily adaptable to inclusion on various surgical instruments. When a first partially tied surgical knot is converted to a completed knot, the completed knot and its core tube can be removed from the cartridge, and a second partially tied knot secured about a new core tube can be received into the suture cartridge to enable multiple knot placements.
