DESCRIPTION:
BRIEF SUMMARY
This invention relates to a sewing device for use in surgical procedures and, more particularly, relates to a device which can be used in the body of a patient without the need to make an external incision in the patient, the device being controlled externally of the patient, for example by endoscopic means. It has particular application to a sewing device for use in flexible endoscopy, though it is also applicable to devices for use in rigid endoscopy.
Sewing devices of this general type are described in, for example, GB-A-2165559 and U.S. Pat. No. 5,080,663. It is an object of the present invention to provide an improved sewing device and, preferably, one which involves a relatively small number of components and can be of small size.
According to the present invention there is provided a sewing device for passing a thread through a substrate portion, which comprises a hollow needle movable between a first position in which it is out of the said substrate portion and a second position in which it passes through the said substrate portion, and a thread carrier adapted to be attached to the said thread and being receivable within the hollow needle.
Preferably, the sewing device comprises a body which defines a cavity within which the substrate portion can be held, for example by means of suction, and the hollow needle is mounted for movement in the body between the said first and second positions.
Two particular embodiments are described below, one of which is a single stitch sewing device, and the other of which is a multiple stitch sewing device. In the single stitch device the thread carrier is transported by the needle through the substrate as the latter passes from its first position to its second position. When the needle returns to its first position, the thread carrier is left behind. In the multiple stitch device, the same procedure occurs, but it is followed by a further step in which the hollow needle travels from its first position to its second position, picks up the thread carrier, and brings it back with it. A second stitch may be formed during this further step, and, in any case, the whole sequence of steps is repeated as many times as may be required to form the desired number of stitches.
The invention will now be further described with reference to the accompanying diagrammatic drawings, in which:
FIGS. 1 to 3 show successive steps in the operation of a single stitch sewing device according to the invention;
FIG. 4 is a view of the device of FIGS. 1 to 3, showing how the sewing device is connected to an endoscope; and
FIGS. 5 to 9 show successive steps in the operation of a multiple stitch sewing device according to the invention.
Referring first to FIG. 1, this shows the distal end of a flexible endoscope 1, with a sewing device 2 according to the invention secured thereto. The endoscope is provided with a viewing channel, which is not shown, but which would be in that portion of the endoscope which is on the upper side as seen in the drawings and which would, therefore, have a view in a forward direction substantially unimpeded by the sewing device 2. The endoscope is further provided with a biopsy channel 3, and a suction channel 4 the proximal end of which is connected to a source of reduced pressure (not shown). The use of suction in a flexible endoscope is described in detail in the patent specifications identified above, and attention is directed to those specifications for further details.
The sewing device 2 has a tube 5 which communicates with the suction pipe 4 and has a plurality of perforations 6 therein. These perforations communicate with an upwardly open cavity 7 formed in the sewing device.
A hollow needle 8 is mounted in the biopsy channel 3, with its bevelled tip extending into the sewing device. The needle has a channel 9 extending therethrough. A flexible, wire-wound cable 10 has its forward end attached to the rear of the needle 8, and a centre wire 11 runs within the cable 10, along the entire length thereof, and is longitudinally movable with respect thereto.
