Abstract
An endoscopic balloon device and method of using in a laparoscopic surgical procedure such as a cystectomy is disclosed. An intact organ such as an ovary is encapsulated with the endoscopic balloon while the organ remains attached to the body. By inserting instruments into the bag, a surgical procedure is then performed within the bag, for example, a cyst may be removed from an ovary. After cyst removal, the bag is irrigated to remove leakage before withdrawal of the cyst within the bag.
Claims31
A surgical device for enclosing an intact organ to perform a surgical procedure thereon, the device comprising:
- a non-permeable material adapted to be closed over an intact organ while substantially enclosing the intact organ;
- and
- at least one port in the non-permeable material adapted to allow a surgical instrument to pass therethrough to operate on the intact organ.
A surgical device for enclosing an intact organ to perform a surgical procedure thereon, comprising:
- an inflatable bag comprising flexible material and having an opening at a distal end thereof sufficiently large to receive the intact organ and a nozzle at a proximal end thereof adapted to inflate the bag;
- and
- at least one port comprising a one-way valve to allow a surgical instrument to be introduced into the bag to perform a surgical operation on the intact organ contained within the bag without leakage of gas.
A method of performing a cystectomy, comprising:
- introducing an inflatable bag into an abdominal cavity of a patient, wherein a distal end of the inflatable bag has an opening sufficiently large to encapsulate an ovary which is attached to the body;
- positioning the inflatable bag over the ovary to encapsulate the ovary;
- closing the opening of the inflatable bag over an ovarian pedicle;
- inflating the bag;
- and
- introducing one or more instruments into the bag to separate a cyst from the encapsulated ovary.
A method of performing an operation on an intact organ, comprising:
- introducing a non-permeable structure into a body space near to the intact organ;
- enclosing at least a portion of the intact organ with the non-permeable structure, the non-permeable structure defining a working space between the intact organ and the non-permeable structure;
- and
- introducing one or more instruments through the non-permeable structure to perform the operation on the intact organ within the working space.
