摘要: A releasable mechanism such as a cap is adapted for use with an access sheath having an elongate tube and a handle structure disposed at a proximal end of the tube. The releasable mechanism is sized and configured to fit the handle structure, which is shaped like the bell of a horn, to further facilitate use with surgical instrumentation. The releasable mechanism may operate as a separate cap that snaps onto the handle structure to provide access pathways to the sheath. The releasable mechanism may also be disposed at a proximal end of a surgical instrument to be introduced into the access sheath such that it may be interlocked with the sheath. In a method of manufacturing a kink-resistant sheath, a wire is initially coated with a plastic material, the coated wire is then wrapped around a mandrel forming a plurality of windings, and the wound coated wire is heated until the plastic material melts and bonds the windings to form a wire-reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, a thermoset or any plastic material having hard and/or soft durometer. The wound coated wire may be heated by capturing the windings within a shrink tube or compressing the windings in a mold and heating the windings until the sheath is formed. In another aspect of the invention, a mandrel is used as part of an extrusion process. In another aspect of the invention, another coating or outside layer could be formed over the spring reinforcement by dipping in a solvent based solution. In yet another embodiment of the invention, a braid such as a polyester braid may be used instead of or in addition to the coil spring to form a kink-resistant sheath.

摘要: A method of manufacturing a kink resistant sheath includes the steps of coating a wire with a plastic material to form an inner tube, placing a braid over the inner tube, applying a spring reinforcement over the braid and applying a second layer of plastic material over the assembly to form an outer tube of a braided reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, thermoset or any plastic material having hard and/or soft durometer.

摘要: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

摘要: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter through body cavities of varying thicknesses. The retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound, a second ring having a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound, and a sheath disposed between the two rings. Optionally, the second ring may be detachably attached to the sheath to adapt the retractor to body cavities of varying thickness. Additional rings may be disposed along the sheath to provide for adjustment of the distance between the first and second rings. The retractor may also include an expandable foam annulus that can adjust the distance between the first and second rings.
