    摘要： A surgical instrument facilitates tying of a knot in a length of suture material at a remote surgical location. The instrument is comprised of an inner rod having a length of suture wrapped over the rod in a particular pattern. A needle may be secured to a free end of the suture and the pattern of wrapping the suture on the rod enables loops of suture to move off the rod end and over the needle to form a knot in the suture. The inner rod is received in an interior bore of an outer rod for manually controlled reciprocating movement therein. The inner rod is manually retracted into the interior bore of the outer rod to cause the outer rod to move the loops of suture off the inner rod end and over the needle in forming a knot in the suture.

    摘要： A laparoscopic apparatus for tunneling dissection including a hollow tunneling member and an inflatable balloon disposed at the distal end of the tunneling member to form together a blunt tipped obturator. The tunneling member has a bore sized allow the insertion of a conventional laparoscope therein to provide observation during surgical procedures. The laparoscope provides direct observation of dissection through the open distal end of the tunneling member. Observation is provided both when the device is used to tunnel between tissue layers to a region of interest within the body of a patient, and during subsequent balloon inflation when the tissue layers are dissected to cause separation of the tissue layers and the creation of an anatomical working space. After the anatomic space has been created, the device and laparoscope are withdraw through the incision. If needed, a trocar can be inserted into the incision to provide access back to the previously created space where the surgical procedure is to be performed. The anatomic working space may be insufflated with an insufflation gas if required for the particular procedure. The apparatus is prepared for use by inserting the tunneling member into the interior of the balloon, forming the balloon into a generally cylindrical roll about the tunneling member, and preferably, through the use of an integral balloon cover, securing the balloon roll to the tunneling member to form a semi-rigid blunt tipped obturator.
