Abstract:
A method for debriding an infected implant area using a robotic-assisted surgery system. The method includes determining, by a processing circuit associated with a computer, an area to be debrided, the debridement area including at least a surface of an implant or patient tissue, and generating, by the processing circuit, a plan for debriding the debridement area. The method further includes controlling a debridement tool, by the robotic-assisted surgery system, while the debridement tool is used to carry out the debridement plan, and monitoring the debridement by the processing circuit.
Abstract:
Dry anti-microbial powder is applied to an incision or wound and surrounding area. A skin closure device is applied to the incision or wound. The incision or wound is closed, either before the closure device is applied or with closure device application. A sterile island dressing is then be applied over the incision or wound with the closure device and anti-microbial powder applied. The absorbent pad of the dressing can be applied directly over the incision or wound to absorb excess blood, pus, or other exudate. The anti-microbial powder mixes with the exudate before or as the exudate is absorbed. The anti-microbial powder in the exudate mixture reduces bacterial and/or microbial growth in the mixture, thereby reducing the infection risk to the closed incision or wound, as well as reducing fouling of the wound dressing and undesirable smells.
Abstract:
Disclosed herein are novel amine-functionalized porphyrin compounds, as wells as pharmaceutically acceptable salts or esters thereof. The disclosed compounds can be used to impart antioxidant, antiinflammatory, anti-microbial, and/or cell-adhesion specificity to a surface or material in need thereof, such as a surface of an indwelling medical implant, or a marine surface. The porphyrine compounds are characterized by having the following group attached to the porphyrine core through a carboxylate ester group. A is independently an optionally substituted N-heterocyclic aromatic ring; x is independently an integer from 0 to 6; R2 is independently lower aminoalkyl or lower aminoaryl.
Abstract:
A surgical staple cartridge is disclosed comprising a plurality of staples removably stored within the surgical staple cartridge. The staples comprise staple legs which extend from a staple base portion in a parallel and offset plane with respect to a plane defined by the staple base portion. Each staple comprises a center of mass aligned with the staple base portion.
Abstract:
A portable, battery powered electrosurgical wave generator is usable in performing electrically driven medical procedures. The wave generator can be small and lightweight to enable a user to carry and use the wave generator in non-operating room type settings. The wave generator can include a control unit that generates output signals in each of a cutting mode, coagulation mode, and a bipolar mode. The control unit can use a single circuit structure to generate the output signals for the cutting, coagulation, and bipolar modes. The output signals can be generated solely from a voltage produced by an incorporated battery within the generator.
Abstract:
Ein chirurgisches Gewebefusionsinstrument mit zwei relativ zueinander beweglichen Greifstrukturen, die für das Zusammenführen von miteinander zu verbindenden biologischen Gewebeabschnitten gestaltet sind, mit Wärmeerzeugungsmitteln, die den Greifstrukturen zugeordnet sind und bei einer Gewebefusion einen Wärmeeintrag im Bereich einer Verbindungsstelle der biologischen Gewebeabschnitte bewirken, sowie mit einer Stützstruktur, die zwischen den Greifstrukturen gehalten ist und bei einer Gewebefusion mit den Gewebeabschnitten in Wirkverbindung gelangt, ist bekannt. Erfindungsgemäß weist die Stützstruktur wenigstens eine zusätzliche körperliche Funktionsstruktur zur Unterstützung oder Förderung der Gewebefusion auf. Einsatz für zirkuläre Gewebefusionsinstrumente
Abstract:
A method for surgical wound closure includes providing a pre-stressed elastomeric membrane having an aperture enclosed by at least a portion of the membrane; adhering the pre-stressed membrane to dermal tissue of a patient at a surgical procedure site; creating an incision through dermal tissue of a patient at the surgical procedure site at a location defined at least in part by the aperture of the membrane; and contracting the membrane and adhered dermal tissue, such that the aperture and incision created during the surgical procedure are at least partially closed. A kit of parts for adhered contractional wound closure including an unstressed elastomeric membrane, at least one retaining frame configured to apply a stressing force for pre-stressing the membrane, and an adhesive configured to attach the pre-stressed elastomeric membrane to dermal tissue of a patient, is also disclosed herein.
Abstract:
Die Erfindung betrifft ein Rohrschaftinstrument (1) mit einem Rohrschaft (3) an dessen erstem, proximalem Ende (5) ein Griffteil (2) mit einem feststehenden Griffhebel (8) und einem relativ zu diesem schwenkbaren Schenkhebel (13) angeordnet ist und an dessen zweitem, distalem Ende (25) ein mit einem Lagerelement (24) versehenes Werkzeug (4) vorgesehen ist, welches durch Betätigen des Griffteils (2) durch ein im Rohrschaft (3) längs verschiebbar angeordnetes Zugelement (27) verstellbar ist, wobei das Rohrschaftinstrument (1) einen Spülanschluss (40) zum Durchspülen des Rohrschaftes (3) aufweist. Zur Verbesserung der Reinigung ist erfindungsgemäß vorgesehen, dass der Rohrschaft (3) außen-und/oder innenseitig mit einer Kunststoffbeschichtung (36, 37) beschichtet ist.
Abstract:
The present invention relates to a film having an antimicrobial agent with improved resistance to microbial growth. The film can be incorporated into an adhesive construction or a non-adhesive construction. In one combination, a three-layer film can be formed having a first layer comprising a polymeric film, a second layer comprising a polymeric film comprising halogenated hexidines, and a third layer comprising an adhesive. The films are useful in various applications such as medical and health care applications.
Abstract:
An antibiotic-eluting article for implantation into a mammalian subject, produced by an additive manufacturing process wherein a polymeric material is concurrently deposited with a selected antibiotic. The additive manufacturing process may be a selective laser sintering process or a selective laser melting process or a selective heat sintering process or an electron beam melting process. The antibiotic-eluting article may be temporary or permanent orthopaedic skeletal component, an orthopaedic articulating joint replacement component, and/or an external hard-shell casing for an implantable device. One or more bone-growth-promoting compositions may be concurrently deposited with the polymeric material. The implantable device may be a cardiac pacemaker, a spinal cord stimulator, a neurostimulation system, an intrathecal drug pump for delivery of medicants into the spinal fluid, and infusion pump for delivery of chemotherapeutics and/or anti-spasmodics, an insulin pump, an osmotic pump, and a heparin pump.
