Abstract

The present invention is concerned with a device and method for use in surgery, in particular hand assisted laparascopic surgery, the device comprising a flexible sleeve about one end of which is located a plurality of inflatable balloons, such that the sleeve may be located about a surgeon'"'"'s forearm, with the balloons thus circumscribing the surgeon'"'"'s wrist, the balloons being inflated once the surgeon'"'"'s hand and wrist have been inserted into a surgical cavity, in order to distend the surgical cavity, thereby creating a space within which the surgical procedure may be performed.

Claims

1. A surgical device for use in minimally invasive surgery, the device comprising a sleeve having an exit aperture and an entry aperture, the sleeve being shaped and dimensioned to permit the passage of a hand therethrough;

and a distensible member secured to or formed integrally about the sleeve adjacent the exit aperture.

2. A surgical device according to claim 1 in which the distensible member is generally annular in form and is located circumferentially about the sleeve adjacent the exit aperture, preferably at the exit aperture.

3. A surgical device according to claim 1 in which the distensible member comprises a plurality of distensible sections arranged in an annular array or in a series of annular arrays adjacent the exit aperture, preferably at the exit aperture.

4. A surgical device according to claim 3 in which the plurality of distensible sections may be individually, sequentially or simultaneously distended.

5. A surgical device according to claim 1 in which the distensible member is secured to an exterior of the sleeve and is arranged to distend away from the arm, in use.

6. A surgical device according to claim 1 in which the entry aperture has a larger cross sectional area than the exit aperture.

7. A surgical device according to claim 1 in which the sleeve is substantially frustum shaped.

8. A surgical device according to claim 1 in which the sleeve is formed from a flexible material.

9. A surgical device according to claim 1 in which the sleeve is shaped and dimensioned to permit the passage of a surgeon'"'"'s hand therethrough and to accommodate at least a surgeon'"'"'s forearm, in use.

10. A surgical device according to claim 1 in which the sleeve is formed from a fluid impermeable material.

11. A surgical device according to claim 1 in which the device further comprises a reinforcing member located about the entry aperture of the sleeve, in order to hold open the entry aperture.

12. A surgical device according to claim 1 in which the device comprises means operable to seal the exit aperture from the entry aperture.

13. A surgical device according to claim 12 in which the sealing means comprises a one way valve.

14. A surgical device according to claim 1 in which the sleeve is provided with a lubricant on an interior surface thereof.

15. A surgical device according to claim 1 in which the device further comprises means for conveying a fibre optic camera along the length of the sleeve.

16. A surgical device according to claim 15 in which the conveying means comprises a passage extending along the length of the sleeve.

17. A surgical device according to claim 1 in which the device further comprises a cover releasably securable about the entry aperture, in order to fluid-tightedly seal the entry aperture.

18. A surgical device according to claim 1 in which the sleeve is substantially transparent.

19. A surgical device according to claim 1 in which the device further comprises a cuff located circumferentially or annularly about the sleeve adjacent the exit aperture of the sleeve.

20. A method of distending a surgical cavity, the method comprising the steps of;

providing a surgical device according to claim 1;

passing a hand through the sleeve of the device;

inserting at least the distensible member of the device into the surgical cavity; and

distending the distensible member.
