A tool and method for use by a surgeon in the insertion of a hip nail guide pin within upper end of a femur. The tool includes a base for temporary abutment against the femur which base is supported by an initial guide pin in place within the femur. A first guide member is positionably carried by the base and is indexed through 90 degrees for the taking of X-ray photographs within perpendicular planes. An optimum location for a second guide pin is plotted on the resulting X-ray photographs. The surgeon, in inserting the second guide pin, utilizes the first guide member, and a second guide member if necessary, to provide a reference point outwardly spaced from the femur to aid him in seating the guide pin through a window in the femur wall into position within the femur neck and head. A method of inserting a second guide pin is also disclosed.

An abdominal incision suturing apparatus includes a guide element that is inserted and maintained in an abdominal incision by a guide handle. The guide element has a passage for receiving slidably the shaft of a reverse needle. The shaft can be moved axially and rotationally with respect to the guide element by a shaft handle. The reverse needle has a needle at the distal end of the shaft, with a pointed end and an eye for receiving a suture. The guide element defines a sheath for receiving the pointed end of the needle. The guide element and the reverse needle together present a substantially airtight surface for maintaining the pneumoperitoneum pressure in a cannula site incision. Further, the guide element includes markings on its surface, for the user to monitor the depth of insertion via a laparoscope. The shaft handle has a specially shaped groove, and the guide element has an internal pin that protrudes into the groove.

A flexible catheter having an inflatable member at one end for insertion into a body cavity to seal same against fluid loss. A spring component biases the catheter outwardly of the cavity to assure seating of the inflated member against the cavity wall. A disc abuts a body part to load the spring component during catheter insertion. The disc prevents accidental perforation of the uterus and, with the inflated member affords stability to facilitate uterus manipulation. An air line in the catheter wall admits air to the inflatable member. A stiffener enables the flexible catheter to be used for imparting movement to the body part.

A uterine manipulator including a catheter tube with an insertable end adapted to be inserted into the uterus. An adjustable stop adapted to engage the cervix is mounted on and shiftable axially along the catheter tube. The stop is adjusted in position and secured in an adjusted position through operation of a digitally actuated clamp which is positioned outside the external opening of the vagina with the manipulator in place.

An endoscope holder includes a dual-axis pivot assembly mountable to a frame. A telescoping arm assembly is attached at one end to the dual-axis pivot assembly and at the other end to a pivoting endoscope grip. An inner arm section is rotatable relative to an outer arm section. The holder provides pivoting of an endoscope about an incision point on the endoscope shaft spaced from the grip. Manually controlled pressurized locks secure the holder configuration, and thereby the endoscope position.

A method and apparatus for catheterization of a body cavity, the catheterization apparatus having a sheath, a cannula with a blunt end and a stylet with a sharp end. To use the apparatus the three elements are initially arranged with the stylet leading the apparatus. The apparatus is advanced a distance into the flesh of a patient. The apparatus is readjusted leaving the cannula in a leading position. The apparatus is then advanced further into the flesh of the patient and into communication with a body cavity. The apparatus is again readjusted, leaving the sheath in communication with the body cavity.

A stiffener device is usable with a uterine manipulator having a catheter tube and outer sheath. The catheter tube is formed in an arc and has an insertable end adapted to be inserted into the uterus. The sheath terminates in a flange that seats against the cervix. The catheter tube is stiffened by a stainless steel wire that is slightly less than the length of the tube, and terminates in a handle that provides for manual grasping to facilitate manipulation of the wire, and thereby the tube, while the insertable end of the tube is in the uterus. The handle may be a small loop formed as a continuation of the wire stiffener, or may be an elongate cylinder fixedly attached to the end of the wire stiffener. A latching assembly may be used to secure the handle adjacent to the outer tube opening.

A cannula and associated endoscope are secured to an operating table by a mechanical linkage assembly having linear and angular connections. These connections are adjustable for supporting an endoscope extending through an incision. Two angular connections are friction joints that allow manual repositioning of the scope by pivoting about respective orthogonal axes that intersect at a point along the scope that is coincident with the location of the incision.

A tool for assisting the surgeon in the setting of a surgical nail within the head and neck of a femur, the tool including a clamp structure temporarily affixed to the femoral shaft to support an adjustable arm in parallel, offset relationship to the femur. A guide assembly is positionable along said arm to locate first and second guide assembly members adjacent the femur end said members being pivotally mounted to enable their positioning and locking within multiple planes for proper guidance of a guide pin, drill and nail assembly. Interchangeable guide members provide precise, sequential guidance of the above bone penetrating instrumentalities. Calibrations on the tool enable calculated corrections to be set into the tool components and preclude the taking of X-rays simply for verifying the projected path of the guide pin.
