An apparatus for removing a hook embedded within a tissue is presented. The hook has a barb extending from a point section of the hook. The apparatus includes a clamping device configured to secure the hook. A probe is coupled to the clamping device. The probe has a tip portion configured to fit within a space between the barb and the point section of the hook to allow the hook to be removed from the tissue.

An end-effector and a surgical instrument including the end-effector are disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm incudes a clamp jaw, a cantilever electrode, and a clamp arm. The cantilever electrode is biased in a direction toward the clamp jaw and the clamp arm includes a retainer to oppose a biasing force and maintain the cantilever electrode in a substantially flat configuration relative to the ultrasonic blade. A skirt may be disposed around the clamp jaw. The clamp arm pad may include multiple support elements arranged in multiple rows to support the cantilever electrode.

An orthopedic clamp to assist in reducing the displacement between bone ends of a fracture, and to position a fixation device, during open fracture reduction surgery is described. The clamp includes a holder to hold the fixation device against the bone. The clamp may also swivel in relation to the holder while the position of the fixation device remains unchanged.

Systems and methods for operating an end effector include a first jaw, a second jaw, a first actuation mechanism configured to actuate the first jaw and the second jaw toward each other with a first force, and a second actuation mechanism configured to actuate the first jaw and the second jaw toward each other with a second force greater than the first force. The second actuation mechanism is different from the first actuation mechanism. In some embodiments, the first actuation mechanism includes a first pull cable configured to increase an angle between the first jaw and the second jaw and a second pull cable configured to decrease the angle between the first jaw and the second jaw. In some embodiments, the second actuation mechanism includes a lead screw.

Clamping forceps device includes two clamps in pivotal connection to one another and each having an operator end for being operated by a health care provider. The device also includes an extension extending aft of the operator end of each clamp, the extension forming a space therebetween sized to form a disconnecting wedge mechanism for separating a tube from a patient tube connector. Each extension defines a ramped surface increasing in thickness moving from an extension tip towards the operator end.

For controlling a robotic surgical system including arms, consoles, and a controller in communication with the arms and consoles, systems and methods are provided that include receiving a request for selection of a first arm for assignment to a first console, and in response to the request, determining whether the first arm is already assigned, assigning the first arm to the first console, if a determination is made that the first arm is not already assigned, determining whether the first arm is to be deselected from a previous assignment, if a determination is made that the first arm is already assigned, generating an error message, if a determination is made that the first arm is not to be deselected, and deselecting the first arm from the previous assignment and assigning the first arm to the first console, if a determination is made that the first arm is to be deselected.

A gear arrangement including two drive units (210, 220, 310, 320, 410), and two translatory transmission elements (151, 152, 251, 252, 351, 352), to each of which a rotationally movable function unit (141, 142) of a distally arranged two-part end effector (140) can be coupled. The first drive unit (210, 310, 410) has at least one proximally arranged rotation element (311, 411) or a thrust element (210) for opening or closing the end effector (140) by rotation of at least one function unit (141, 142). The second drive unit (220, 320), with which the translatory transmission elements (151, 152, 251, 252, 351, 352) are movable in opposite directions, has at least one proximally arranged rotation element (224, 320, 421) for simultaneous and unidirectional pivoting of the function units (141, 142) of the end effector (140). A surgical instrument includes the gear arrangement (200, 300, 400) in the handle (180).

Conventional vasectomy techniques suffer from a number of disadvantages and potential complications, including, for example, a substantial risk for the development of hematomas, swelling, and post-surgical pain, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing vasectomy instruments, kits, and methods that allow for a rapid, reliable, less invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

Devices, methods, and systems are provided for placing an implant into a patient and removing it therefrom.

A surgical instrument includes a female instrument part that defines a hollow volume in a coupling region and a male instrument part that forms a guide section in the coupling region. The guide section is configured to at least partially pass through the hollow volume. A pivoting element, which has an upper section, a center section, and a lower section, couples the female instrument part and the male instrument part to each other in such a way that the female instrument part and male instrument part can pivot relative to each other about an axis of rotation of the pivoting element. A lateral upper contact step is formed between the upper section and the center section of the pivoting element and a lateral lower contact step is formed between the lower section and the center section of the pivoting element.
