Abstract: A surgical clamp includes a support frame clamp member, a retraction shaft clamp member and a handle linked to the support frame clamp member and the retraction shaft clamp member for moving the clamp members between loosened and tightened positions. Both the support frame clamp member and the retraction shaft clamp member permit transverse attachment. The shaft clamp and the support frame permit pivoting of the retraction shaft relative to the support frame. The handle is always in alignment with the retractor shaft, with a gripping portion extending above and in line with the shaft but attached to the clamp below the shaft. With this clamp and handle configuration, the clamp maintains a very low profile while still allowing easy access to the handle from above during the tightening and/or loosening motions, permitting a single handed “scissors action” tightening.

Abstract: A surgical clamp includes a support frame clamp member, a retraction shaft clamp member and a handle linked to the support frame clamp member and the retraction shaft clamp member for moving the clamp members between loosened and tightened positions. The shaft clamp and the support frame permit pivoting of the retraction shaft relative to the support frame. The handle is disposed to move through a throw of less than 90°, always outside the support frame and always in alignment with the retractor shaft. For a standard orientation of the clamp, the tightening throw is vertically upward, on a handle which is balanced and aligned relative to the pivot axis and possibly relative to the connection of the frame clamp to the support frame.

Abstract: A shaped surgical retractor blade is used in a surgical retractor assembly. The shaped retractor blade is not formed of sheet material but rather is formed to have a non-uniform thickness between the tissue contacting side and the surgical arena side. The non-uniform thickness can be provided by a longitudinally running rib running between two recesses on surgical arena side of the retractor blade. The recesses provide openings through which the surgeon can better view the surgical arena. The rib provides additional bending strength to the retractor blade. The tissue contacting side of the blade can have a convex curvature, minimizing the possibility of tissue damage at the location that the blade contacts the tissue. The retractor blade can have a constant longitudinally extending section and a distal, tapering section.

Abstract: A retractor system includes an adjustable arm having a proximal end and a distal end where a cable is disposed through the adjustable arm from the proximal end to the distal end. A housing is attached to a proximal end of the adjustable arm. The proximal end has a carriage movably disposed therein that engages one end of the cable. A tensioning mechanism is positioned within the housing wherein the tensioning mechanism applies a force to the cable to provide tension to the cable when the carriage is in a non-tensioning position. An activating device engages the carriage where manipulation of the activating device moves the carriage and provides tension to the cable which stiffens the adjustable arm.

Abstract: A method of performing surgical retraction of flesh includes positioning a patient on a surgical table and making an incision into the flesh of the patient. A retractor support is mounted to the surgical table and positioned proximate the incision with a blade positioned within the incision and having a flexible member attached to the blade. The retractor blade is positioned manually to retract flesh. The flexible member in tension is attached to the retractor support thereby retracting the flesh and exposing the surgical site.

Abstract: A retractor for use in a minimally invasive surgical procedure includes a handle having a blade attached to the handle. The blade includes a flesh retaining portion that attaches to and extends from the handle. A flesh engaging portion extends from the flesh retaining portion where a width of the flesh engaging portion is less than or equal to two centimeters. A tab extends from a distal end of the flesh engaging portion and wherein the tab separates flesh from the surgical site.

Abstract: A method of performing knee-joint surgery includes positioning the tibia and the femur such that the knee-joint is disposed in a bent position. An incision is made to expose the knee-joint. A retractor support is mounted to a surgical table. The skin and flesh layers proximate the knee-joint are retracted utilizing a retractor that is attached to the retractor support which is mounted to a surgical table.

Abstract: A minimally invasive coronary anastomosis procedure includes providing an incision in an intercostal space between two ribs of a patient, the incision providing access to a selected anastomosis site on a blocked coronary artery. A spreader device is inserted between the two ribs, the spreader device spreading the two ribs apart to sufficiently widen the incision for the procedure to be performed through the incision. An internal mammary artery is dissected from the thoracic wall, and the heart is pharmaceutically treated to substantially reduce its heartbeat. The blocked coronary artery is clamped at two spaced-apart positions at the selected anastomosis site. The blocked coronary artery is incised, and the dissected internal mammary artery is sutured to the incision at the anastomosis site.
