Description

APPARATUS AND METHOD FOR ILLUMINATING A PEP lTONEAL CΛ' /lPi DURING LAFAPOSCOFIC SUPGER

BACKGROUND OF THE INDENTION

Field of the Invention

This invention relates generally to apparatus and methods associated with laparoscopic surgery, and more specifically to illumination devices adapted for use in hand-assisted laparoscopic surgery.

Discussion of Related Art

In laparoscopic surgery there is need for a sealing device which can seal around the surgeon's hand while permitting use of the hand in the pressurized peritoneal space. In the past, laparoscopic surgery has been viewed through a laparoscopic camera which supplies its own illumination. It is not uncommon for this illumination to be less than desirable, but there have been few options available to the surgeon to increase the illumination of the surgical field. Laparoscopic illumination of the past has also been accomplished solely with point-source lighting. This has tended to create shadows which have made it even more difficult to perceive the three dimensional environment. SUMMARY OF THE INVENTION

In accordance with the present invention, a hand-assisted laparoscopic device is provided with transparent characteristics facilitating the transmission of light into and out of the abdominal cavity. As disclosed and claimed in

Applicant's co-pending application, Serial No. 60/449,857, filed on February 25, 2003 and entitled Hand-Assisted Laparoscopy Apparatus and Method, this laparoscopic device may take the form of a pad which is placed over an incision extending through the abdominal wall. The pad can be formed of a gel material and provided with a slit to facilitate access for the surgeon's hand and other instruments into the abdominal cavity.

In accordance with the present invention, the gel forming the laparoscopic pad can be provided with translucent characteristics and preferably transparent characteristics. An external light can then be shown through the pad to illuminate the surgical environment. The transparent characteristics also operate to facilitate the surgeon's visualization of the operative site through the transparent device

The illumination is preferably provided by a plurality of lamps in order to avoid shadows. The lamps can be carried by the transparent device and spaced around the slit. Preferably the lamps will be at least partially disposed within the transparent gel.

In one aspect, the invention includes a surgical valve adapted for use in a surgical procedure to access a body cavity through an incision in a body wall. The valve has a generally open state facilitating formation of a first seal in the presence of an instrument extending through the incision and into the body cavity The valve has a generally closed state facilitating formation of a second seal in the absence of the instrument extending through the incision and into the body cavity. A valve body is formed of a seal material and provided with a size sufficient to cover the incision. Perimeter seal means is carried by the seal material and adapted to form a perimeter seal with the body wall around the incision. Portions of the valve body define a slit and operate to form the first seal and the second seal. The slit extends through the valve body within the perimeter seal. A source of light is carried by one of the valve body and the perimeter sea) means for lighting the body cavity through the incision to facilitate visualization of the surgical environment.

In another aspect, the invention includes a source of light which is disposed relative to the valve body and produces an omni-directional light for illuminating the surgical environment. The omni-directional light tends to eliminate shadows'in the body cavity. These and other features and advantages of the invention will become more apparent with a description of preferred embodiments and reference to the associated drawings.

DESCRIPTION OF PREFERRED EMBODIMENTS AND BEST MODE OF THE INVENTION

The hand»assisted laparoscopic device is disclosed and claimed by

Applicant in United States Patent Application Serial No. 60/449,857 filed on February 25, 2003, and entitled Hand-Assisted Laparoscopy Apparatus and Method. This application, which is fully incorporated herein by reference, discloses a hand-assisted laparoscopic device 10 in the form of a pad 12. The pad 12 is adapted for placement on a body wall, such as the abdominal wall 14, and forms a seal with the wall 14 around an incision 16 which extends through the wall 14 and into a body cavity, such as the abdominal cavity 18. A slit 21 extending through the pad 12 communicates through the incision 16 with the abdominal cavity 18, In operation, the pad 12 is placed on the abdominal wall 14 over the incision 16. With this disposition, a primary seal is formed between the abdominal wall 14 and the perimeter of the pad 12. This seal is intended to maintain the inflation or pnβumoperitoneum of the abdominal cavity 18 during laparoscopy surgery. This primary seal can be facilitated by a wound retractor including an internal anchor or ring 15 and an elastomeric sheath 1 .

Various laparoscopic devices, including the surgeon's hand, can be inserted through the slit 21 to perform surgical procedures within the abdominal cavity 18. In the presence of these instruments, including the surgeon's hand, a secondary seal must be formed around the instrument by the material defining the slit 21 ,

In a preferred embodiment, this material includes a gel with elastomeric and compliant characteristics sufficient to form the secondary seal around the instrument, such as the surgeon's wrist. In accordance with the present invention, the gel material forming the device 10 is provided with translucent characteristics to facilitate the transmission of light to and from the abdominal cavity 18. In a preferred embodiment, the translucent material is effectively transparent.

As illustrated in Figure 2, the transparent characteristics of the pad 12 facilitate the illumination of the abdominal cavity 18, for example, with an exterior light source 23. Even a unidirectional light source, such as a lamp 25 can be used in this manner as its light will be somewhat diffused by the pad 12 to provide for omni-directional illumination of the abdominal cavity 18. Of course the transparent characteristics of the device 10 also facilitate the transmission of light outwardly from the abdominal cavity 18 to permit visualization represented schematically in Figure 2 by an observer's eye 27.

The hand-assisted laparoscopic device 10 provides a large base which can be used to support several of the lamps 25 or other devices to illuminate the peritoneum cavity, as illustrated in Figure 3. This illumination can be in the form of fiberoptic lighting, illumination lamps or even LED's which can be carried by the device 10 and in some cases built directly into the device 10. The lamps 25 are preferably positioned around the perimeter of the device in order to supply even illumination to the operating field. With multiple sources of illumination, troublesome shadows can be minimized.

As illustrated in the embodiment of Figure 3, the multiple illumination lamps 25 can be embedded in the gel of the pad 12 in order to provide omnidirectional illumination within the abdominal cavity 18. Not only does this provide for total illumination of the abdominal cavity, but it does so without producing the three-dimensional shadows of the past. As noted, the lamps 25 can be carried by the gel of the device 10, partially embedded in the gel of the device 10, or even fully embedded in the gel of the device 10. In the latter case, the transparency of the gel is of particular importance, It can be seen from the foregoing discussion that laparoscopic illumination can be facilitated with intrinsic illumination devices, providing an omni-directional light within the abdominal cavity 18. Even extrinsic illumination can be accommodated with a transparent hand-assist device which facilitates illumination of the abdominal cavity and direct visualization of the operative site. In either case, the illumination devices can be carried by the hand-assist device, or partially or totally embedded within the device.

Notwithstanding the foregoing description, it will be understood that many other modifications can be made to the various disclosed embodiments and method steps, without departing from the spirit and scope of the concept. For example, various sizes of the surgical device are contemplated as well as various types of constructions and materials. It will also be apparent that many modifications can be made to the configuration of parts as well as their interaction. For these reasons, the above description should not be construed as limiting the invention, but should be interpreted as merely exemplary of preferred embodiments. Those skilled in the art will envision other modifications within the spirit and scope of the present invention as defined by the following claims.
