    摘要: A wound protector and retractor device 1 comprises a sleeve 2, a distal member provided by a distal ring 3 of resilient material and a proximal member provided by a proximal ring 4. The sleeve 2 is led around the ring 3 and is free to move axially relative to the distal ring 3 somewhat in the manner of a pulley. The proximal ring 4 is fixed to the sleeve 2, in this case at the proximal inner end thereof. The sleeve 2 terminates in a handle or gripping portion which is reinforced by a gripping ring 15. The sleeve extends from the proximal ring 4 and the distal ring 3 is contained between inner and outer layers 2a, 2b of the sleeve 2. The resilient distal ring 3 is scrunched up and inserted through the incision 6. The sleeve 2 is then pulled upwardly. On pulling of the sleeve 2 upwardly the outer layer 2b is pulled up while the inner layer 2a is drawn around the proximal ring 3. This results in shortening the axial extent between the proximal ring 4 and the distal ring 3, tensioning the sleeve and applying a retraction force to the margins of the incision 6. As the incision is being retracted the margins are also protected by the sleeve. On retraction, an access port is provided, for example for a surgeon to insert his hand and/or an instrument to perform a procedure. The device may be used as a retractor in open surgery or as a base for a valve/seal to allow it to be used in hand assisted laparoscopic surgery or for instrument access or hand access generally.

    摘要: A surgical access system (100) comprises an access port (5), a rigid cannula having a shaft (11) and a laparoscopic surgical instrument (101). The access port (5) comprises a seal (6) and a retractor. The retractor comprises a distal O-ring (71), an outer proximal ring member (77), an inner proximal ring member (78) and a sleeve (72). The sleeve (72) extends distally from the inner proximal ring member (78) to the distal O-ring (71) in a first layer, is looped around the distal O-ring (71), and extends proximally in a second layer between the inner proximal ring member (78) and the outer proximal ring member (77). The instrument (101) comprises a shaft (103) with a rigid proximal region (104), a flexible intermediate region (105), and a rigid distal region (106). The instrument shaft (103) may be inserted through the cannula shaft (11). The instrument (101) has a rigid end effector (107) releasably coupled to the distal end (108) of the instrument shaft (103). An actuator (109) for actuating the end effector (107) is provided at the proximal end (110) of the instrument shaft (103). The actuator (109) is movable along the instrument shaft (103) parallel to the longitudinal axis of the instrument shaft (103).

    摘要: An instrument access device (1) comprises an instrument seal, a wound retractor for retracting a wound opening (2), and an opening element for at least partially opening the seal to facilitate insertion of an instrument (6) through the seal. The instrument seal comprises a gelatinous elastomeric seal (3) with a pinhole opening (4) extending therethrough, and a housing (5) around the seal (3). The opening element may be employed to at least partially open the pinhole opening (4) to facilitate insertion of the instrument (6) through the pinhole opening (4). The opening element comprises a sheet (11) of flexible material. The sheet (11) is movable distally relative to the seal (3) between a rest configuration and an opening configuration. In the rest configuration the sheet (11) is substantially planar. In the opening configuration, the pointed, the leading end (16) of the sheet (11) enters the pinhole opening (4) and moves distally through the pinhole opening (4) to at least partially open the pinhole opening (4).
