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 comprises a base which is mounted to a proximal ring assembly of a retractor. A first, second and third connector sleeves connect first, second and third seal assemblies to a connector base. The connector sleeves are of a laterally flexible and longitudinally rigid material. At least some of the first, second and third seal assemblies comprise a lipseal through which an instrument is inserted and a second seal having a passageway through which the instrument is insertable. At least one of the seal assemblies has a reducer cap which has a further lipseal. To insert large diameter instruments the cap is removed. To insert smaller diameter instruments the cap is in place. The access device has two insufflation/desufflation ports.

A cannula (1) comprises a distal hollow tubular section (2), a proximal instrument insertion section (3), a lip seal (4) for sealingly engaging with an instrument shaft (5), and a duck-bill seal (10) also for sealingly engaging with the instrument shaft (5). The lip seal (4) is movably coupled to the proximal section (3) by a coupling section, provided in the form of a flexible tubular sheath section (6). The distal section (2) defines an access channel (7) for extension of the instrument shaft (5) therethrough. The proximal section (3) has a proximal opening (8) through which the instrument shaft (5) may be inserted into the proximal section (3). The distal end of the flexible section (6) is fixedly attached to the proximal section (3), and the proximal end of the flexible section (6) is fixedly attached to the lip seal (4). The flexible section (6) facilitates relative movement between the lip seal (4) and the proximal section (3) to accommodate lateral movement of the instrument (5) while maintaining the seal between the lip seal (4) and the instrument (5).
摘要:
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.
摘要:
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.
