DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to surgical devices, and in particular to surgical pouches and retractors.
BACKGROUND ART
During laparoscopic and endoscopic surgery pouches or bags have been used to remove the products of surgical excision through narrow apertures in the patient's body. Such pouches include plastic sleeving, tied at one end, and latex condoms. However, these tend to split and spill their contents within the body cavity. This limitation seriously restricts their use.
The present invention seeks to provide a durable pouch for a variety of types of surgical procedure.
SUMMARY OF THE INVENTION
According to a first aspect of the invention there is provided a surgical device comprising a collapsible compartment having an opening therein joined to an elongate member, wherein the compartment is formed from ripstop nylon material.
In a preferred arrangement, the material is polyurethane coated.
Preferably, the elongate member comprises a flexible tape.
Alternatively, the elongate member comprises a tube leading to the opening.
Preferably, the device has means to position the compartment attached thereto. Said means may comprise one or more tapes, webs, strings or rods.
According to a second embodiment of the invention there is provided a surgical device comprising a collapsible compartment formed from a woven plastics material having an opening therein, joined to an elongate member, characterized in that an elongate sleeve runs over the outside of the compartment and is closed at one end.
In a preferred embodiment, the sleeve runs down the compartment and may be closed at the end remote from said opening.
According to a third aspect of the invention there is provided a surgical device comprising a collapsible compartment having an opening therein joined to an elongate member, wherein the device is formed from a single sheet of material joined by a seam.
According to a fourth aspect of the invention there is provided a surgical apparatus comprising a flexible compartment having an opening therein joined to an elongate member, and a further flexible elongate member formed to be inserted into the compartment, along or adjacent to the elongate member, to form a looped support within the compartment.
In a preferred arrangement, the inserted rod returns out of the opening in the compartment.
Preferably, the rod is mounted on a hollow tube.
According to a fifth aspect of the invention there is provided a surgical apparatus comprising a flexible compartment having an opening therein joined to an elongate member, and an elongate sleeve running over the outside thereof, the sleeve being closed at one end, and a further flexible elongate member formed to be inserted into the sleeve.
According to a sixth aspect of the invention there is provided a method of using a surgical device comprising a flexible compartment having an opening therein joined to an elongate member, comprising the steps of: forming a puncture portal through the wall of a body cavity, inserting a cannula into the puncture portal, inserting the device into the cavity inside a second cannula whilst retaining the distal end of the elongate member, and inserting a further, flexible elongate member along or adjacent to the elongate member into the opening compartment to form a looped support within the compartment.
According to a seventh aspect of the invention there is provided a method of surgery using a surgical pouch as previously described, together with a cannula, and an endoscopic surgical instrument, the method comprising the steps of forming a puncture portal through the wall of a body cavity, inserting the cannula through the puncture portal to facilitate access to said body cavity, inserting the surgical pouch into the cavity through the cannula whilst retaining the distal end of the elongate member, and carrying out endoscopic surgery through the cannula with the endoscopic instrument.
According to an eighth aspect of the invention there is provided a method of removing a relatively large organ or part thereof fro
