A surgical access sealing device comprises expansile chambers (306, 307,308, 309) which define inflation spaces. An upper layer (304) in one case comprises two chambers (306, 307) which are overlapped when uninflated. A lower layer (305) comprises two chambers (308, 309) which are also overlapped, when uninflated. The region of overlap between the chambers (306, 307) of the first layer is offset from the region of overlap between the chambers (308, 309) of the second layer. The walls of the inflated chambers are movable for passage of an object such as a surgeon's arm / hand whilst maintaining a seal.
An instrument such as a tenaculum comprises a pair of jaws (202, 203) which are pivotal from an open configuration in which the jaws (202, 203) are splayed apart to a closed low profile delivery configuration. The jaws (202, 203) each have tissue engagement features (201). A protector loop (200) for each jaw which may be of a shape memory material such as Nitinol provides a safety protective distal tip which is distal of the tissue engaging features (201). The atraumatic tip does not harm tissue and does not compromise the integrity of a bag which may be used as a containment device in a procedure such as a hysterectomy.
A valve component (1) of the invention comprises a main valve (2) which is located on a centre line and at least one auxiliary valve (3) which is located radially outwardly of the main valve (2). The main valve may be used for sealing engagement with a cannula. In some cases the cannula may be used for introduction of a number of robotically controlled surgical instruments generally, including a camera. The auxiliary valves (3) may be utilised to introduce another instrument through the valve component. The valve component is mounted in a manner which ensures that the valve component (1) is rotatable about a centre line through the axis of the valve component (1). This ensures that the valve component (1) can be rotated relative to a cannula inserted through the main valve (2) and consequently that the auxiliary valves (3) are rotatable relative to the cannula allowing the auxiliary valves (3) to be positioned to facilitate optimum access and manipulation for an auxiliary instrument(s) inserted through the auxiliary valve(s) (2).
An artificial pneumoperitoneum bag device (800) comprising an inflatable bag having an opening at an end of the bag. The bag device also includes an indicator (1000) including at least one repeating pattern such as grid lines (1002) on a wall of the bag. The pattern may extend across at least one side of the bag.
An inflatable artificial pneumoperitoneum bag (800) for receiving tissue (840) during laparoscopic surgery has a tissue-receiving opening at a proximal end thereof defined by a cuff (811) at the proximal opening. The cuff (811) has a closed configuration for delivery and retrieval of the bag (800) and an open configuration to receive tissue. The cuff (811) is biased into the open configuration. The bag (800) has a main body which extends from the cuff and the main body of the bag is more flexible than the cuff (811). A biasing element (815) bias's the cuff (811) into the open configuration. A tether (809) is used to close the bag for retrieval. The bag (800) creates an artificial pneumoperitoneum which isolates tissue within the bag.
A bag with one or more openings is placed within a body cavity. Excised tissue is placed within the opening of a deflated bag. One or more openings of the bag are withdrawn outside the body cavity and the bag is inflated. Instruments including laparoscopic visualization are placed within the inflated bag that remains within the body cavity. The tissue retained within the bag is morcellated/crushed/reduced and removed. The bag is deflated and removed with residual tissue/blood/fluids inside. The tissue to be removed is retained in the bag which prevents potentially harmful material such as cancerous cells from being released in the body cavity.
An instrument access device (1) comprises a wound protector and retractor (2), a proximal assembly (3) coupled to the wound protector and retractor (2), and an instrument receiver (5) which can be releasably coupled to the proximal assembly (3). The instrument receiver (5) has a valve assembly (6) through which an instrument (7) is passed and a cannula portion (8) which extends in use through an incision which has been retracted and protected by the retractor (2). The instrument receiver (5) has an insufflation/desufflation port (9). The proximal assembly (3) comprises an inner proximal ring member (40) and an outer proximal ring member (41). The proximal end of the retractor sleeve (25) is located between the proximal ring members (40, 41). The inner proximal ring member (40) has a slot (43) for receiving and releasably engaging with an insufflation port section (45) of the instrument receiver (5). Because the cannula portion (8) extends through the retracted and protected incision there is minimal frictional resistance to the insertion of an instrument through the retracted incision. The distal end of the cannula portion 8 may be located close to the inner surface of the abdominal tissue which minimises restriction on movement of an instrument within the abdomen - the cannula provides minimal obstruction to this internal movement. Curved instruments may be readily inserted.
An instrument access device 1 comprises a proximal member 25 for location externally of an opening into a body cavity. A first connector 20 extends between the proximal member 25 and a first instrument receiver 2. A second connector 21 extends between the proximal member and a second instrument receiver 3. Instrument seals can be housed in relatively rigid housings for added strength.
A surgical sealing device 1 for providing hand or instrument access during a surgical procedure is mounted to a wound retractor device 10 which is used to retract the sides of an opening into an internal cavity. The sealing device 1 comprises a first sealing member 5 and a second sealing member 6. The second sealing member 6 has passageway 2 with a sidewall of an elastic material to create a seal between the sidewall of the passageway 2 and an object passing through the passageway 2. The first sealing member 5 is in the form of a flap of flexible material and is moveable relative to the second sealing member 6 between a closed configuration sealing the passageway 2 and an open configuration. The flap member 5 may be fixedly attached to the second sealing member 6 by means of a reception loop 7 formed at the distal surface of the second sealing member 6.

The passageway (6) is movable from the closed configuration to the open configuration upon insertion of the instrument (7) through the passageway (6). The passageway (6) is biased towards the closed configuration, such that upon removal of the instrument (7) from the passageway (6), the passageway (6) moves automatically from the open configuration to the closed configuration. The second seal (3) may be a lipseal valve with a passageway (8) extending therethrough. An instrument (7) may be inserted through the passageway (8). The passageway (8) is biased towards the open configuration, such that upon removal of the instrument (7) from the passageway (8), the passageway (8) moves automatically from the sealed configuration to the open configuration.
