Abstract
An endoscopic surgical device for an endoscopic surgical procedure includes a slotted clear cannula with a tubular body having a distal end, a proximate end and a slot extending longitudinally therethrough. A pair of wings near the proximal end of the slotted clear cannula extend outward from the tubular body. The tubular body is made from a transparent material. The slotted clear cannula may be part of an endoscopic surgical blade assembly in which the cannula is attached to a housing enclosing a blade slidably oriented in the cannula. A kit comprising the endoscopic surgical device and a method for a performing a uniportal endoscopic surgical procedure using the endoscopic surgical device are also described.
Core Innovation
The invention relates to an endoscopic uniportal surgical system and device for performing an endoscopic surgical procedure. The device includes a housing having a proximate end and a distal end, and a slotted clear cannula or slotted tube attached to the distal end of the housing. The slotted clear cannula or slotted tube comprises a cannula body or tube body with a slot extending from the proximate end substantially to the distal end of the body.
Within the housing, the invention provides a rotatable mechanism or a mechanism reversibly pivotable between at least two positions for deploying an internal blade. The mechanism includes a slide pusher assembly having a notch, and a blade having an upper cutting surface and a lower cutting surface forming respective upper and lower angles with a bottom surface. A substantially cylindrical body comprising a selector switch allows engagement of the blade for deployment, with the blade residing at the notch in a pre-deployment position and including a tab that embeds into a pusher base.
The system further includes a tube assembly or tube mounting assembly located within the housing and routed through the cylindrical selector body to connect to the slotted clear cannula or slotted tube from the proximate end. The distal end outside the housing has a closed end that is tapered. The disclosed surgical procedure is selected from a listed group including carpal tunnel release, cubital tunnel release, plantar fascia release, lateral release for patella realignment, trigger finger release, and various fascia compartment releases in the upper and lower extremity.
Claims Coverage
The document includes two independent claims. Each claim defines a device architecture with a slotted clear or transparent cannula or tube, an internal blade deployment mechanism using a notch and selector switch in a pre-deployment position, and a tapered closed distal cannula or tube end, for a listed group of endoscopic release procedures.
Slotted clear cannula attached to housing
A slotted clear cannula attached to the distal end of the housing, comprising a cannula body with a slot extending from the proximate end substantially to the distal end.
Rotatable blade deployment mechanism with notch and selector switch
A rotatable mechanism located within the housing comprising a slide pusher assembly comprising a notch, a blade with an upper cutting surface forming an upper angle with a bottom surface and a lower cutting surface forming a lower angle with the bottom surface, and a substantially cylindrical body comprising a selector switch, wherein the blade resides at the notch in a pre-deployment position and the selector switch allows engagement of the blade for deployment, and wherein the blade comprises a tab that embeds into a pusher base.
Tube assembly routed through cylindrical selector body with tapered closed cannula end
A tube assembly having a proximate end and a distal end, wherein the distal end is located within the housing and extends through the cylindrical body, and wherein the tube assembly connects to the slotted clear cannula from the proximate end of the cannula body, with the slotted clear cannula distal to the housing having a closed end that is tapered.
Procedure limited to listed endoscopic releases
The endoscopic surgical procedure is selected from the group consisting of carpal tunnel release, cubital tunnel release, plantar fascia release, lateral release for patella realignment, release of radial tunnel, release of pronatar teres, release of trigger finger, release of lacertous fibrosis, release of extensor tendons for lateral epicondylitis, release of medial epicondylitis, release of posterior and other compartments of a leg, forearm fascia release for fascial compartment syndrome, and release of fascial compartments in an upper and a lower extremity.
Slotted transparent tube attached to housing
A slotted tube attached to the distal end of the housing, comprising a tube body with a slot extending from the proximate end substantially to the distal end.
Reversibly pivotable blade deployment mechanism with selector switch
A mechanism located within the housing reversibly pivotable between at least two positions, comprising a slide pusher assembly comprising a notch, a blade with an upper cutting surface forming an upper angle with a bottom surface and a lower cutting surface forming a lower angle with the bottom surface, and a substantially cylindrical body comprising a selector switch, wherein the blade resides at the notch in a pre-deployment position and the selector switch allows engagement of the blade for deployment, and wherein the blade comprises a tab that embeds into a pusher base.
Tube mounting assembly through cylindrical selector body with transparent slotted tube and tapered closed distal end
A tube mounting assembly having a proximate end and a distal end, wherein the distal end is located within the housing and extends through the cylindrical body, and wherein the tube mounting assembly is connected to the slotted tube from the proximate end of the tube body; the slotted tube is transparent; and the slotted tube distal to the housing has a closed end that is tapered.
Procedure limited to listed endoscopic releases
The endoscopic surgical procedure is selected from the group consisting of carpal tunnel release, cubital tunnel release, plantar fascia release, lateral release for patella realignment, release of radial tunnel, release of pronatar teres, release of trigger finger, release of lacertous fibrosis, release of extensor tendons for lateral epicondylitis, release of medial epicondylitis, release of posterior and other compartments of a leg, forearm fascia release for fascial compartment syndrome, and release of fascial compartments in an upper and a lower extremity.
Across both independent claims, the core claim coverage centers on a device with a slotted clear or transparent cannula or tube attached to a housing, an internal notch-based blade deployment mechanism controlled by a cylindrical selector switch in a pre-deployment position, and a tapered closed distal cannula or tube end outside the housing, for a defined list of endoscopic tunnel and fascia compartment release procedures.
