  • Publication number: 20170086930
    Abstract: A cannula mount for a surgical system may include a body having an aperture to receive a portion of a cannula. The cannula mount may further include a pivotable clamping arm to engage the portion of the cannula received in the aperture. The clamping arm may include a cam follower surface. The cannula mount may further include a block moveable between a first position and a second position. The block may include a cam surface. The cam surface of the block may engage the cam follower surface of the clamping arm in the first position to actuate the clamping arm to a closed position in which the clamping arm engages the portion of the cannula received in the aperture. The clamping arm may be permitted to move to an open position in which the clamping arm does not engage the cannula when the block is in the second position.

  • Patent number: 8870900
    Abstract: Devices, systems and methods related to endoscopic surgery, particularly related to robotic surgical operations, provide a tissue stabilizer for endoscopically stabilizing a target tissue within a patient's body. For stabilizing a beating heart during a closed-chest coronary artery bypass grafting procedure, a stabilizer is inserted through an endoscopic cannula and provides sufficient surface area to contact the heart and effectively stabilize the target tissue area. The stabilizer can straddle a blood vessel, such as a coronary artery, which is targeted for an anastomosis. Vessel occlusion fasteners may occlude the target blood vessel prior to the anastomosis procedure.

  • Publication number: 20140018824
    Abstract: Surgical accessories are presented in vivo and used by surgical tools in the surgical site to perform additional tasks without the need to remove the tools from the surgical site for tool change or instrument loading. The accessories can be introduced into the surgical site by a dedicated accessory introducer, or can be supported on the body of a surgical tool inserted into the surgical site and be manipulated using another surgical tool in the surgical site. The accessory introducer can be resiliently biased to bias the accessories toward a predetermined position in the surgical site.

  • Patent number: 8182476
    Abstract: Surgical accessories are presented in vivo and used by surgical tools in the surgical site to perform additional tasks without the need to remove the tools from the surgical site for tool change or instrument loading. Examples of in vivo accessories include fastening accessories such as surgical clips for use with a clip applier, single working member accessories such as a blade which can be grasped and manipulated by a grasping tool for cutting, sheath accessories that fit over working members of a tool, flow tubes for providing suction or introducing a fluid into the surgical site, and a retraction member resiliently biased to retract a tissue to expose an area in the surgical site for treatment. The accessories can be introduced into the surgical site by a dedicated accessory introducer, or can be supported on the body of a surgical tool inserted into the surgical site and be manipulated using another surgical tool in the surgical site.

  • Publication number: 20100251514
    Abstract: A caster assembly includes a primary wheel and a secondary wheel. As the caster assembly is rolled against and over an obstacle threshold, the secondary wheel is positioned to contact the obstacle threshold first. As the caster assembly begins to roll over the threshold, the secondary wheel lifts the caster assembly part way. As the caster assembly continues to roll over the threshold, the primary wheel contacts the threshold and lifts the caster assembly over the obstacle threshold. One or more secondary or primary wheels may be used. The secondary wheel or wheels may be positioned to remain within a sweep volume of the primary wheel as the caster assembly swivels around a caster swivel axis.

  • Patent number: 6451027
    Abstract: A positional control system, comprising a robotically controlled arm, for varying the position of a robotic surgical tool, is provided. The robotic surgical tool can be in the form of an image capture device, such as an endoscope, for example. The positional control system comprises a base and a mounting formation arranged to support the robotic surgical tool. The positional control system further comprises an articulated arm extending between the base and the mounting formation. The articulated arm has an upper arm portion, a forearm portion, a forearm link member and an upper arm link member. The portions and the link members are pivotally secured relative to one another to effect displacement of the mounting formation relative to the base. The forearm link member is positioned at least partially within the forearm portion and the upper arm link member is positioned at least partially within the upper arm portion.
