    摘要: The present invention provides a multiple cannula assembly which includes an inner cannula having a first balloon for making an elongated cavity by progressive dissection, an endoscope for visually monitoring the dissection, and an outer cannula having a second balloon for enlarging the elongated cavity. The inner cannula is independently movable from the outer cannula and is reversibly extendible beyond the distal end of the outer cannula. The present invention also includes a method of using such a cannula assembly for dissecting an elongated cavity along the course of a small blood vessel and subsequently harvesting the blood vessel.

    摘要: Method and apparatus for reconstructing target tissue by grafting uses a stabilizing balloon cannula having an endoscope for visualizing the placement of the graft during the procedure. The method and apparatus advances a sheathed graft to the target tissue, releases the graft at the target site, occludes the target tissue, deploys a graft stabilizing catheter, dissects a cavity outside the target tissue site, maintains the dissection site, and then secures the graft to the target tissue. Alternatively, the method and apparatus creates a cavity extending to the target tissue using an everting balloon cannula with an endoscope, maintains the dissection site, introduces the graft to the target site via the dissection site, and then secures the graft to the target tissue.

    摘要: The invention provides an apparatus and method for manipulating parts of the body in surgical procedures, particularly useful for peritoneal distension in laparoscopic surgery. The apparatus comprises a positionable support structure having an extendible horizontal arm rotatably mounted to an extendible vertical post, the post having a clamp at its lower end for mounting to a surgical table. An end segment at the distal end of the horizontal arm has a mount for mounting end-of-arm tooling, for example, peritoneal distension instruments. Locking mechanisms are disposed in the horizontal arm, vertical post and end segment to lock the support structure in a desired position. A motor is disposed within the vertical post for power-assisted extension and retraction of the vertical post. Preferably, the locking mechanisms and motor are controllable using switches mounted on the end segment. The method comprises providing a support structure as described mounted to a surgical table, positioning the distal end of the horizontal arm over a patient on the table, activating locking mechanisms in the horizontal arm and vertical post to lock the support structure in position, attaching peritoneal distension instruments to the distal end of the horizontal arm, and vertically extending the vertical post while the horizontal arm remains locked relative to the post, thereby distending the peritoneum of the patient.

    摘要: A device for mounting a tubular sleeve for an obturator of a trocar to a patient's body includes a sleeve-holding part for attaching to the sleeve and a skin-fixation part for attaching to the patient's skin surface. The sleeve-holding part may be formed by an annular washer made of an elastic material which permits a user to move it longitudinally with respect to the sleeve so as to adjust their relative positions. The skin-fixation part may be a crossbar and a cord attached to the washer at one end and to the crossbar at the other. The cord is stapled to the patient's body for fixation.

    摘要: Intrapericardial access is provided by clamping the wall of the pericardium between elongate jaw elements carrying axially aligned tubular guides and passing a guide wire through the guides and the pericardial tissue therebetween. In the preferred embodiment the jaw elements include interengageable ratchets for holding the elements in clamping engagement with the wall of the pericardium and aligned pointed extensions for piercing the pericardial tissue clamped between the elements. Further intrapericardial access is provided by an additional tubular guide carried by the jaw element intended to be disposed in the pericardium during placement of the guide wire.

    摘要: A system for closure of a fascial opening is disclosed. The system may include a first capture device for pulling one end of a suture through fascial tissue on one side of a fascial opening, and a second capture device for pulling an opposing end of the suture through the fascial tissue on an opposite side of the fascial opening. A trapping device for locating and engaging the first capture device can be used, prior to the capture device being pulled through the fascial tissue, so that the trapping device can subsequently pull the suture to facilitate closure of the fascial opening. Methods and apparatuses for closure of a fascial opening are also disclosed.
