  • Patent number: 10117646
    Abstract: A method for retracting body tissue providing a retractor system that includes a rail having two opposed widened rail portions separated by a narrowed portion, each widened portion engageable by a separate clamp. The clamps are configured to support the rail to a fixed surface, or to support a surgical device. Each clamp may independently be positioned or slid along the rail to a desired location without interference with a clamp on an opposing widened rail portion. A device clamp is formed of spherical mating portions which enable alignment of a surgical device along six degrees of freedom, and tightenable by securing a single fastener. A retractor blade mount enables an angular and tilting disposition of a retractor blade, as well as remote manipulation of the retractor blade.

  • Patent number: 8858538
    Abstract: Apparatus and methods are described allow the techniques of endoscopic and laparoscopic surgery to be combined into a minimally invasive hybrid surgical technique called NOTES-assisted laparoscopic surgery. Manual and robotic-controlled versions of a modular laparoscopic tool are described having a small diameter shaft that is delivered laparoscopically to a surgical site. Larger diameter working tips are delivered through a NOTES delivery tube inserted to the surgical site through a natural orifice and joined to the shaft of the modular laparoscopic tool. Larger diameter working tips improve the effectiveness of the modular laparoscopic tools and the number and size of laparoscopic ports used can also be reduced.

  • Patent number: 8827902
    Abstract: An instrument for spinal surgery for retracting soft tissue and mounting between a superior spinous process and an inferior spinous process includes a relatively rigid frame, a first retractor blade mounted to the frame and a distractor element movably mounted to the frame. The distractor element has a body, a proximal end and a distal end. The distractor element has a thickness and a length. The distractor element is configured for mounting between the superior and inferior spinous processes in a working configuration. The distractor element is generally tapered at the distal end in an insertion configuration. The instrument also includes an insertion shaft attached to the proximal end and a first shaft joint mounted between the frame and the insertion shaft.

  • Patent number: 8821393
    Abstract: A vaginal manipulator includes a shaft attached to a head and a door connected to the head. The head has an anterior side opposite a posterior side and includes a core fixed to the shaft and a sleeve coupled in a sliding relationship to the core. The door is coupled to the core and is movable relative to the posterior side of the head through an opening provided in the sleeve. A proximal end of the core defines a proximal end of the head and a distal end of the sleeve defines a distal end of the head. The proximal end of the core is fixed to the shaft. The sleeve moves relative to the core to provide the head with an adjustable length between the proximal end of the head and the distal end of the head.

  • Patent number: 8808172
    Abstract: A method for laterally accessing a lumbosacral intervertebral disc space of a patient includes positioning the patient laterally and making an incision to provide lateral access to the patient's iliac crest. A bracket (24) may be placed on the iliac crest and a retractor (28) may be attached to the bracket such that a distal end of the retractor is positioned over the lumbosacral intervertebral disc space while a proximal end of the retractor provides an entry space for a surgeon to insert at least one tool (90). The surgeon may perform a surgical procedure on the lumbosacral intervertebral disc space through a channel (49) defined by the retractor.

  • Patent number: 8771179
    Abstract: A surgical retention port particularly useful as an arthroscopic port for shoulder surgery is provided. The surgical retention port has an inner cannula defining a throughbore, a plurality of rotatable fingers coupled to the inner cannula, and an outer cannula extending around the inner cannula. Rotation of the inner cannula relative to the outer cannula causes the rotation of the fingers from a first position where the fingers assume a collapsed configuration to a second position where the fingers assume an extended or open configuration.

    Abstract: A retractor includes a handle portion, a blade portion coupled to the handle portion. The blade portion is configured for insertion into an internal region of a patient. The blade portion includes a first portion configured to manipulate tissue of the patient. In an embodiment, a locator element is configured to highlight an external region of the patient to indicate to a user the location of the first portion in the internal region. In an embodiment, a signal-transmission medium is coupled to the blade portion and has a port. An overmolded camera unit has a lens and is configured to couple with the port. When the camera unit is coupled with the port, the lens is oriented to capture images of the internal region.
