1. Apparatus for use in minimally invasive surgery through a wound into an insufflated cavity, comprising:
- an outer sleeve of gas-impermeable supple material having an entry opening at a proximal end thereof and an exit opening at a distal end thereof;
first sealing means adapted to seal the exit opening gastightly around the wound in a patient; and
second sealing means adapted to seal the entry opening gastightly around a surgeon'"'"'s arm received therein and create thereby a gastight chamber in said outer sleeve when a surgeon'"'"'s arm is operatively received in said sleeve;
whereby the sleeve cooperates with the first and second sealing means to enable the surgery to be performed under insufflatable conditions.

Abstract
Apparatus and method for hand-assisted minimally invasive laparoscopic surgery which allows for palpation and biophysical feedback within a sterile environment. A sleeve provides a sealed chamber communicating with a wound accessible to an surgeon'"'"'s hand through entry and exit openings. The entry opening is sealed around the surgeon'"'"'s wrist or forearm by a cuff.

20. Apparatus for use in hand-assisted minimally-invasive surgery in a sufflatable body cavity having an outer surface, comprising:
-
an elongate flexible sleeve having an end portion adapted to be positioned adjacent the body cavity and a proximal end portion adapted to be positioned away from the body; means defining an exit opening laterally of said flexible sleeve adjacent to said distal end portion; means defining an entry opening co-axially of said flexible sleeve at said proximal end portion; first sealing means carried by said sleeve and surrounding said exit opening and adapted to engage said body outer surface; second sealing means carried by said sleeve and surrounding said proximal end portion adapted to seal gastightly a surgeon'"'"'s arm; and means in said sleeve between its distal and proximal end portions providing a normally-closed flexible valve adapted to open upon insertion of the surgeon'"'"'s hand toward the distal end portion of the sleeve and automatically close gastightly upon withdrawal of the surgeon'"'"'s hand, said valve providing a third sealing means co-operable with said first sealing means to define a substantially gastight chamber in communication with said exit opening; whereby the surgeon can readily insert and withdraw the hand from the body cavity in the course of surgery without significant loss of pressure in the body cavity when sufflated. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. Apparatus for use in hand-assisted minimally invasive surgery in a gas sufflatable body, comprising:
-
an elongate flexible sleeve having a lateral exit opening at one location and an axial entry opening at another location; first means adapted to seal gastightly said sleeve around said exit opening to a body surface undergoing minimally invasive surgery; second means adapted to seal gastightly said sleeve around a surgeon'"'"'s arm adjacent to said entry opening; and means providing a duckbill check valve in said sleeve for preventing gas flow from said exit opening to said entry opening when said second sealing means is unsealed; whereby a surgeon may insert and withdraw the hand through the exit opening without significantly affecting gas pressure in the sufflated body.

28. Surgical apparatus for use in minimally invasive surgery for introducing a hand or instrument through a wound into an insufflated cavity comprising:
-
protective sleeve means of gas-impermeable material having a distal end adapted to be inserted through the wound for overlapping the lower edge thereof, and a proximal end formed to extend out of the wound; an inside sealing ring, operatively connected to said sleeve means in proximity to the distal end, adapted to self-seal gastightly around the inside of the wound; an outside sealing ring, operatively connected to said protective sleeve means in proximity to the proximal end thereof and forming with said first sealing means a gastight chamber in said protective sleeve means and adapted to seal gastightly around the outside of the wound; an elongate gas-impermeable supple sleeve extending laterally of said outside sealing ring; and means providing a gastight-seal on said elongate sleeve at an end thereof remote from said outside sealing ring; whereby the wound is protected by the protective sleeve while insufflation gas is contained within the elongate sleeve. - View Dependent Claims (29, 30, 31)
