    摘要: Die Erfindung betrifft ein Verfahren zur Entfernung des Chorions unter Bereitstellung einer Spreizpinzette, welche mindestens drei Spitzen umfasst, die endseitig an Pinzettenarmen vorliegen. Bei dem Verfahren erfolgt zunächst ein Durchstoßen des Chorions an den mindestens drei Punkten mittels der Spitzen sowie ein anschließendes Aufspreizen der Pinzettenarme, sodass sich zwischen den mindestens drei Punkten eine Öffnung, vorzugsweise eine polygonale Öffnung, in dem Chorion bildet, aus welcher der Embryo heraustreten kann. In einem weiteren Aspekt betrifft die Erfindung eine Spreizpinzette zur Durchführung des Verfahrens sowie ein System umfassend eine Spreizpinzette und einen Antrieb, welcher zur automatisierten Durchführung des Durchstoßen und Öffnen des Chorions konfiguriert ist. In bevorzugten Ausführungsformen wird das Verfahren zur Dechorionierung einer Vielzahl von Embryonen innerhalb eines Hochdurchsatz-Verfahrens, vorzugsweise zur automatisierten Testung der Wirkung von Substanzen auf Embryonen, genutzt.

    摘要: A surgical fastening device includes a handle assembly, an elongated portion, a shell assembly, a screw drive, and a firing mechanism. The elongated portion extends distally from the handle assembly. The shell assembly is disposed adjacent a distal portion of the elongated portion, and includes a cartridge assembly and an end effector. The screw drive defines a longitudinal axis. A distal portion of the screw drive is engaged with the end effector. Rotation of the screw drive about the longitudinal axis relative to the elongated portion causes longitudinal translation of the end effector relative to the cartridge assembly. The firing mechanism is disposed at least partially within the end effector. A predetermined amount of proximal movement of the end effector relative to the cartridge assembly is configured to at least partially form fasteners disposed in the cartridge assembly.

    摘要: Various embodiments relate generally to surgical instruments, tools, and apparatuses for medical use, including, but not limited to, forceps, tweezers, and pincers, as well as other anatomical tools for surgical and medical uses, and, more specifically, to surgical instruments implementing a coupling member to effectuate multiple pivot axes enhance, for example, effective lengths with which to access an internal surgical site. In some examples, a surgical instrument may include lever members, each of which may include a pivot portion, a force application portion, and a contacting portion. The surgical instrument may also include a coupling member configured to position multiple pivot portions adjacent proximal ends of a first and second lever member to effectuate a closing state at which contacting portions are positioned at a second distance, which is less than the first distance, at distal ends of a first and second lever member.

    摘要: Certain embodiments provide a surgical instrument comprising surgical instrument comprising an device having a functional end and a main handle comprising a distal end coupled to the device. The surgical instrument further comprises an actuation handle insert comprising a number of first rolling components and an actuation tube coupled to the actuation handle insert, wherein the functional end of the device at least partially extends outside of the actuation tube when the device is deactivated. The surgical instrument further comprises levers comprising second rolling components. The surgical instrument further comprises a plurality of rolling elements, wherein each of the rolling elements is placed between one of the second rolling components and one of the first rolling components and pressing one or more of the levers pushes the actuation handle insert forward relative to the device, causing the actuation tube to transition the device from the deactivated state to an activated state.

    摘要: An endoscopic tool (100) for facilitating injection of fluid (121) into a submucosal layer of tissue includes a first cannula (124), a suction source (128), a fluid lumen (132), and a second cannula (136). The first cannula (124) has a suction surface (144) disposed at a distal end (146), and defines a suction lumen (148). The suction source (128) is coupled to the first cannula (124) and creates a negative pressure within the suction lumen (148). The second cannula (136) is disposed in a fluid lumen (132) separate from the suction lumen (148), is adapted to be coupled to a source of fluid (138), and carries a needle (140) at a distal end (139) thereof. The tool (100) draws the mucosal layer via the suction, which enlarges the submucosal layer, and injects a fluid into the enlarged portion of the submucosal layer via the needle (140), thereby creating a raised portion of tissue around the injection site.
