Abstract

A laparoscopic surgical device including a wound protector, a sleeve, and a surgical glove. The wound protector has inner and outer inflatable cuffs joined by a protector member. The protector member has a passageway extending longitudinally therethrough. The surgical glove includes a cuff portion having an end segment and a wrist segment. The end segment is doubled over the wrist segment to form an annular cavity. The sleeve includes first and second oppositely disposed end portions having first and second openings, respectively. The first opening forms a rim which is positioned in a crevice formed between the outer surface of the outer cuff and the outer surface of the protector member. The second end portion is positioned and clamped within the annular cavity by the end segment of the surgical glove. The inner cuff is inserted through the incision and the inner and outer cuffs are positioned adjacent the patient'"'"'s abdominal wall. The inner and outer cuffs are inflated, clamping the patient'"'"'s abdominal wall therebetween and clamping and sealing the rim of the first opening in the crevice. The surgical glove and a portion of the sleeve may be inserted through the passageway of the wound protector into the patient'"'"'s abdomen.

Claims

1. A laparoscopic surgical device for protecting the walls of an incision in a patient'"'"'s abdominal wall and facilitating the insertion of a surgeon'"'"'s hand through the incision comprising:

a wound protector having inner and outer cuffs and a protector member extending longitudinally therebetween, the protector member defining a passageway extending longitudinally therethrough, the inner and outer cuffs each defining an annular cavity and being composed of an elastic material, the protector member and the outer cuff each having an outer surface, the outer surface of the outer cuff and the outer surface of the protector member defining a crevice, the wound protector further having a first fluid passage in communication with the cavity of the inner cuff and a second fluid passage in communication with the cavity of the outer cuff; and

a sleeve member having first and second oppositely disposed end portions, the first end portion defining a first opening forming a rim positioned in the crevice of the wound protector;

wherein the inner cuff is insertable through the incision, whereby the inner and outer cuffs are positioned adjacent the patient'"'"'s abdominal wall and the protector member is positioned in the incision, a pressurized fluid is injectable into the cavities of the inner and outer cuffs via the first and second fluid passages wherein the inner and outer cuffs inflate to clamp the patient'"'"'s abdominal wall therebetween and the outer cuff inflates to clamp and seal the rim of the first opening in the crevice, and the pressurized fluid is removable from the outer cuff via second fluid passage wherein the outer cuff deflates to unclamp the rim of the first opening whereby the sleeve member is removable from the wound protector.

2. The laparoscopic surgical device of claim 1 wherein the inner and outer cuffs each has a wall including a substantially circular inner and outer wall portions joined by an engagement wall portion disposed adjacent the protector member and a distal wall portion disposed oppositely the engagement wall portion.

3. The laparoscopic surgical device of claim 2 wherein the inner, outer, engagement, and distal wall portions of the inner and outer cuffs each have a thickness, the thickness of the engagement wall portion of each cuff being smaller than the thickness of the inner, outer and distal wall portions.

4. The laparoscopic surgical device of claim 2 wherein the inner cuff, the outer cuff, and the protector member are formed as a single, unitary structure.

5. The laparoscopic surgical device of claim 1 further comprising a surgical glove mounted to the second end portion of the sleeve member, the second end portion of the sleeve member defining a second opening providing communication with the surgical glove.

6. The laparoscopic surgical device of claim 5 wherein the first and second openings are each elastically stretchable.

7. The laparoscopic surgical device of claim 5 wherein the protector member is a tubular sleeve defining a longitudinally extending passage, the second end portion of the sleeve member and the surgical glove being insertable through the passage of the protector member into the abdomen of the patient.

8. The laparoscopic surgical device of claim 7 wherein the sleeve member further has protector end and glove end transitions portions disposed adjacent the first and second end portions, respectively, the outer cuff being disposed substantially within the protector end transition portion when the second end portion of the sleeve member is inserted through the passage of the protector member.

9. The laparoscopic surgical device of claim 8 wherein the first and second openings each have an inside diameter and the protector end and glove end transition portions each have a diameter, the diameter of at least a portion of the protector end and glove end transition portions being greater than the inside diameters of the first and second openings, respectively.

10. The laparoscopic surgical device of claim 5 wherein the surgical glove has a glove portion and a cuff portion including an end segment and a wrist segment extending between the end segment and the glove portion, at least a part of the cuff portion being elastically stretchable for clamping and sealing the surgical glove to the surgeon'"'"'s hand.

11. The laparoscopic surgical device of claim 10 wherein the end segment is doubled over the wrist segment forming an annular cavity, the second end portion of the sleeve member being disposed in the annular cavity.

12. The laparoscopic surgical device of claim 11 wherein at least a portion of the end segment is elastically stretchable for clamping the second end portion of the sleeve member to the cuff portion.

13. The laparoscopic surgical device of claim 12 wherein the cuff portion further includes first and second elastic strips mounted to the end segment and wrist segment, respectively, the first elastic strip clamping the second end portion of the sleeve member to the cuff portion and the second elastic strip clamping and sealing the surgical glove to the surgeon'"'"'s hand.

14. The laparoscopic surgical device of claim 1 wherein the second portion of the sleeve member comprises an endcap which covers the outer cuff and prevents communication through the patients abdominal wall via the incision.

15. The laparoscopic surgical device of claim 1 wherein the protector member comprises inner and outer walls defining an annular void therebetween and the wound protector further includes a third fluid passage in communication with the void.

16. A laparoscopic surgical device for protecting the walls of an incision in a patient'"'"'s abdominal wall and facilitating the insertion of a surgeon'"'"'s hand through the incision comprising:

a wound protector having inner and outer inflatable cuffs and a protector member extending longitudinally therebetween, the protector member defining a passageway extending longitudinally therethrough, the protector member and the outer cuff each having an outer surface, the outer surface of the outer cuff and the outer surface of the protector member defining a crevice;

a sleeve member having first and second oppositely disposed end portions, the first end portion defining a first opening forming a rim positioned in the crevice of the wound protector;

wherein the inner cuff is insertable through the incision, whereby the inner and outer cuffs are positioned adjacent the patient'"'"'s abdominal wall and the protector member is positioned in the incision, the inner and outer cuffs are inflated to clamp the patient'"'"'s abdominal wall therebetween and the outer cuff is inflated to clamp and seal the rim of the first opening in the crevice.

17. A laparoscopic surgical device for protecting the walls of an incision in a patient'"'"'s abdominal wall and facilitating the insertion of a surgeon'"'"'s hand through the incision comprising:

a wound protector having inner and outer inflatable cuffs and a protector member extending longitudinally therebetween, the protector member and the outer cuff each having an outer surface, the outer surface of the outer cuff and the outer surface of the protector member defining a crevice, the protector member defining a passageway extending longitudinally therethrough;
