Fig. 16(d)(ii) illustrates a rear view of the clip 30 with the funnel top 31.
In Fig. 16(d)(iii) the introducer 4 is pushed until the distal ring 52 is compressed in the clip 30. The funnel 31 aids compression. In the embodiment of Figs. 16(e) to 16(g) the holder element 40 is provided in the form of a tubular element. The tubular element 40 has a funnel part 41 which tapers radially inwardly distally. The funnel part 41 extends' from the proximal end of the tubular element 40 to the distal flange part 42.
Fig. 16(f) illustrates that the taper 41 extends over the entire height of the streamlining clip 40.
In the embodiment of Fig. 16(h) the holder element 50 is provided in the form of a tubular element. The tubular element 50 is attached to the wound retractor device 2. In this case the tubular element 50 is attached to a release ribbon 51 of the wound retractor device 2. The release ribbon 51 may be employed to release the distal ring 52 of the wound retractor device 2 from a retracting configuration when it is desired to remove the distal ring 52 from the wound opening 3.
Fig. 16(h) illustrates the restraining sleeve 50, the ribbon 51, and the wound retractor device 2.
In the embodiment of Figs. 16(1) to 16(n) the holder element 60 is provided in the form of a tubular element. In this case the tubular element 60 is not arranged concentrically around the conveying device 4 in the holding configuration. Instead the tubular element 60 is arranged radially offset from the conveying device 4 in the holding configuration (Fig. 16(k)). The tubular element 60 and the conveying device 4 are located in a side-by-side arrangement (Fig. 16(k)). The tubular element 60 is slidable relative to the conveying device 4 from the holding configuration to the release configuration (Figs. 16(1) to 16(n)).
Figs. 16(i) to 16(n) illustrate the restraining clip 60 for keeping the distal 'O'-ring 52 compressed while being inserted. Fig. 16(i) illustrates the restraining clip 60, the ribbon 51 attached to the clip 60, and the 'O' ring 52 on the hook 6. Fig. 16(j) illustrates the clip 60 sliding up over the ring 52 only. Fig. 16(k) illustrates the ring 52 compressed and the clip 60 sliding off.
Fig. 16(m) illustrates that as the introducer 4 is pushed into the skin, the clip 60 slides off. Fig. 16(n) illustrates the clip 60 attached to the ribbon 51.
In the embodiment of Figs. 16(o) to 16(t) the holder element 70 is provided in the form of a tubular element. The tubular element 70 has two openings 71 in the side walls of the tubular element 70 (Fig. 16(o)). Each opening 71 is provided in the form of an elongate slot.
The tubular element 70 is slidable relative to the conveying device 4 from a storage configuration in which the distal ring 52 of the wound retractor device 2 is released (Fig. 16(s)) to the holding configuration (Fig. 16(t)), and from the holding configuration (Fig. 16(t)) to the release configuration.
As illustrated in Fig. 16(p), in the storage configuration the tubular element 70 is arranged concentrically around the distal ring 52, with the distal ring 52 extending through the openings 71.
Fig. 16(o) illustrates the side slots 71 which allow the distal ring 52 to be pre-loaded in this streamlining clip 70. The slots 71 ensure that the ring 52 is not compressed. Thus the shelf-life is enhanced.
Fig. 16(p) illustrates the distal ring 52 loaded in the streamlining clip 70. The ring 52 is unrestrained due to the side slots 71.
Fig. 16(q) illustrates the distal ring 52 attached onto the hook 6. The streamlining clip 70 with the side slots 71 is then placed over the distal ring 52. This step may take place during manufacture. The surgeon would therefore not have to load the clip 70 onto the ring 52.
Fig. 16(r) illustrates the bladeless hook introducer 4, the streamlining clip 70 with the side slots 71 and the distal ring 52. Fig. 16(s) illustrates the base of the streamlining clip 70 engaging the skin, and the incision 3.
Fig. 16(t) illustrates that as the hook introducer 4 advances through the abdominal wall, the distal ring 52 becomes compressed by the streamlining clip 70. The ring 52 therefore passes through the wound opening 3 more easily.
The tip 80 comprises a main body portion 81 and two side wing elements 82. Each of the wing elements 82 is movable relative to the main body portion 81 between a narrowed configuration (Fig. 19) and a widened configuration (Fig. 21). In this manner the width of the distal tip 80 may be adjusted. By adjusting the width of the distal tip 80, the size of the wound opening 3 created may be varied to suit particular requirements. The tip 80 has a flattened, non-symmetrical shape in cross-section (Figs. 20 and 22). The wing elements 82 are movable relative to the main body portion 81 in a direction parallel to the major axis of the tip 80.
As illustrated in Fig. 23, the apparatus 90 is asymmetrical about the longitudinal axis
A-A of the conveying device 4. In particular the handle 91 is radially offset from the longitudinal axis A-A of the conveying device 4. Because the handle 91 is radially offset from the longitudinal axis A-A, this provides for ease of passage of the laparoscope 93 through the lumen 92.
In Figs. 26 and 27 there is illustrated another apparatus 200 according to the invention, which is similar to the apparatus of Fig. 18, and similar elements in Figs.
26 and 27 are assigned the same reference numerals. In this case the conveying device 4 comprises a resilient flap 201 which extends across the foil width of a passageway 202 between the concave portion of the hook element 6 and externally of the conveying device 4. The passageway 202 facilitates location of the distal ring 52 in engagement with the hook element 6. The flap 201 may be used to selectively obstruct the full width of the passageway 202 to retain the distal ring 52 of the wound retractor device 2 in engagement with the hook element 6.
