TL;DR: In this article, a surgical system for performing a surgical procedure includes an ex-vivo positioning mechanism and an invivo instrument magnetically attracted to the exvivo position mechanism.
Abstract: A surgical system for performing a surgical procedure includes an ex-vivo positioning mechanism and an in-vivo instrument magnetically attracted to the ex-vivo positioning mechanism. The in-vivo instrument can be positioned within a patient by moving the ex-vivo positioning mechanism. In addition, the surgical system includes a percutaneous member introducible into the patient independent from the ex-vivo positioning mechanism, the percutaneous member comprising a connector at a distal end thereof, wherein the connector is selectively couplable to the in-vivo instrument within the patient.

18 Feb 2016TL;DR: In this article, an energy source for use with an electrosurgical system is disclosed. In one embodiment, the energy source includes a power supply, one or more capacitors coupled to the power supply and a switching component coupled to one or multiple capacitors.
Abstract: An energy source for use with an electrosurgical system is disclosed. In one embodiment, the energy source includes a power supply, one or more capacitors coupled to the power supply, and a switching component coupled to the one or more capacitors. The switching component is configured to output pulses of a biphasic waveform. The pulses are capable of treating undesired tissue by inducing a change in voltage potential across cell membranes of a plurality of cells in the undesired tissue to promote non-thermal cell death in the plurality of cells. The pulses are also capable of treating the undesired tissue with no or minimal muscle contractions in patient tissue within reach of the biphasic waveform during treatment of the undesired tissue.

02 Aug 2012TL;DR: In this paper, the authors propose a framework to transition the first expandable portion from a contracted state to an expanded state by expanding the first perimeter of the first electrode along an axis.
Abstract: A surgical instrument, such as an electrical ablation device, includes an elongate member having therealong disposed a first electrode extending along an axis. A first expandable portion extends along the axis and defines a first perimeter of the first electrode and has an associated first diameter with respect to the axis. The first expandable portion includes a first framework selectively expandable to transition the first expandable portion from a contracted state to an expanded state. The first framework is selectively contractible to transition the first expandable portion from the expanded state to the contracted state. When the first framework is expanded, the first diameter is expanded and the first expandable portion is transitioned from the contracted state to the expanded state. When the first framework is contracted, the first diameter is contracted and the first expandable portion is transitioned from the expanded state to the contracted state.

TL;DR: In this article, a surgical system includes a surgical instrument, an end-effector, a control circuit, and a sensor configured to transmit a sensor signal indicative of a closure parameter of the end effector.
Abstract: A surgical system includes a surgical instrument, an end effector, a control circuit, and a sensor configured to transmit a sensor signal indicative of a closure parameter of the end effector. The control circuit is configured to adjust a closure rate of change parameter and the closure threshold parameter based on perioperative information received from one or more data sources and a sensor signal received from the sensor.

TL;DR: In this article, a method of compressing tissue during a surgical procedure is described, where the end effector comprises a first jaw and a second jaw, and a communication pathway between the surgical instrument and a surgical hub is established.
Abstract: A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

TL;DR: In this article, a surgical device for stapling and fastening body tissues, consisting of an insertion section extending from an operation section for insertion into a body cavity, and a stitching member connected to a distal end of the insertion section, for treating body tissues with a high-frequency current within the body cavity.
Abstract: A surgical device for stapling and fastening body tissues, comprises an insertion section extending from an operation section for insertion into a body cavity, stapling member connected to a distal end of the insertion section, for treating body tissues with a high-frequency current within a body cavity. The stapling member includes an anvil and a cartridge between which the tissues are sandwiched, and a cutter. Staples are applied to the anvil from the cartridge for stapling the tissues and the cutter cuts the tissue while it applies a high-frequency current thereto.

21 May 1986TL;DR: In this paper, the use of stress-induced martensite decreases the temperature sensitivity of the devices, thereby making them easier to install and/or remove, and thus reducing the cost.
Abstract: Medical devices which are currently proposed to use elements made from shape memory alloys may be improved by the use of stress-induced martensite alloy elements instead. The use of stress-induced martensite decreases the temperature sensitivity of the devices, thereby making them easier to install and/or remove.

TL;DR: An endoscopic bipolar forceps as mentioned in this paper includes an elongated shaft having opposing jaw members at a distal end thereof, which are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to each another to a second position wherein jaw members cooperate to grasp tissue therebetween.
Abstract: An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.
