摘要:
A wound protector and retractor device comprising a longitudinal axis, a distal member, a proximal member, and a sleeve extending at least between the distal member and the proximal member. The sleeve has a proximal gripping portion for pulling the sleeve upwardly to shorten an axial extent located between the distal member and the proximal member.

An instrument access device (500) comprises a distal O-ring (11) for insertion into a wound interior, a proximal member for location externally of a wound opening and a sleeve (12) extending in two layers between the distal O-ring (11) and the proximal member. The proximal member comprises an inner proximal ring member (25) and an outer proximal ring member (24) between which the sleeve (12) is led. A seal housing (300) is mounted to the inner proximal ring member (25). A gelatinous elastomeric seal (302) with a pinhole opening (303) therethrough is received in the housing (300). An instrument may be extended through the seal (302) to access the wound interior through the retracted wound opening in a sealed manner.

A wound retractor device (1) comprises a distal ring member (2) for insertion into a wound opening (3), a proximal ring member (4) for location externally of the wound opening (3), and a cylindrical connecting sleeve (5), which extends between the distal ring member (2) and the proximal ring member (4), to retract laterally the sides of the wound opening (3). The device (1) further comprises a rigid ring-shaped platform member (6) to support one or more medical devices in a desired location and/or orientation. The platform member (6) is suitable for location, in use, externally of the wound opening (3). The device (1) also comprises a medical device (16) supported on the platform member (6). The medical device (16) comprises a body portion (9), a gripping member (11), and a rigid arm member (10) to connect the gripping member (11) to the body portion (9). A medical instrument (14) may be then positioned in a “C”-shaped opening (21) of the gripping member (11). The location and/or orientation of the medical instrument (14) may be adjusted by adjusting the arm member (10) and/or the gripping member (11).
摘要:
A device to aid advancement of a colonoscope through the colon of a patient comprises an elongate body defining a colonoscope lumen. The body provides a fluid tight seal to the colonoscope. The body has an anchor to releasably anchor the interior wall of the colon to the device to enable a colonoscope to be more easily advanced. The anchor may be provided by suction apertures through which a suction is applied to draw the colon into anchored engagement with the body. The anchor may be provided by a balloon and/or foam based anchoring systems may be provided.

An instrument access port comprises a retractor (811) for retracting the sides of an incision (813) and a valve (829) for sealing around an instrument (814) inserted through the retracted incision (813). The retractor (811) comprises a distal member for insertion into the incision (813), a proximal member for location externally of the incision (813) and a retracting member for extending between the distal member and the proximal member. The valve (829) is coupled to the retractor (811) to define a low profile sealed instrument access port.
摘要:
A wound retractor system comprises a retractor having a distal ring 91 and a retracting sleeve 4 extending from the ring. An insertion tool 120 has a distal groove 122 to hold the ring for insertion of the ring through a small incision 90 in the abdominal wall 97. The retractor may be used for retracting an incision to receive an instrument therethrough. A seal or valve may be mounted to the retractor through which an instrument can pass.
摘要:
An apparatus (650) for inserting a distal ring (9) of a wound retractor device (2) through a wound opening comprises a bladeless tip (641) for creating the wound opening by forcing tissue apart, and a conveying device (5) for conveying the distal ring (9) through the wound opening. The conveying device (5) comprises a hook element (6) for engaging the distal ring (9) to convey the distal ring (9) through the wound opening, and a receiver housing (651) for receiving a seal (652) and a proximal ring (653) of the wound retractor device (2) to hold the seal (652) and the proximal ring (653) externally of the wound opening, and thus maintain a sleeve portion of the wound retractor device (2) in tension, during conveying of the distal ring (9) through the wound opening.

The proximal member comprises an inner proximal ring member (25) and an outer proximal ring member (24) between which the sleeve (12) is led. A seal housing (300) is mounted to the inner proximal ring member (25). A gelatinous elastomeric seal (302) with a pinhole opening (303) therethrough is received in the housing (300). An instrument may be extended through the seal (302) to access the wound interior through the retracted wound opening in a sealed manner.
摘要:
An instrument access device comprises first, second and third instrument seals for sealing around instruments extended through the device. The seals have respective connector sleeves. Each sleeve connects a base to one of the instrument seals. The device also comprises two insufflation/desufflation ports. Each of the ports comprises a connector extending from the base, a tube extending from the connector, a luer connector and a removable cap. The luer connector is used for connection to any suitable supply line for insufflation gas or for discharge if insufflation gas. In use, the insufflation/desufflation ports facilitate independent control of insufflation and desufflation as may be required during a surgical procedure. Access sleeve at the proximal end is cut-off, folded over the inner proximal ring and is held in place between the base and the inner proximal ring when the base is fitted. The proximal end of the sleeve that is generated when the sleeve is pulled upwardly to retract an incision is removed from the field of use.
摘要:
An instrument insertion device (1) comprises a first seal (2), a second seal (3), a first proximal ring (4) for location externally of a wound opening, and a second proximal ring (5) for location externally of the wound opening. The first seal (2) may be a tricuspid valve defining a passageway (6) extending therethrough. An instrument (7) may be inserted through the passageway (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.
