Abstract

A spongestick for .Iadd.retraction, and tissue manipulation in .Iaddend.endoscopic procedures including a hollow stem of substantially cylindrical cross-section with a longitudinal groove along its outer surface and having a handle at one end and a balloon receptor portion at the other end. The stem is surrounded by a retractable sheath having a handle at the end adjacent the stem handle. A balloon system comprises a Leur lock tip at its upper end for coupling to inflation means and an elongated tube portion which extends within the longitudinal groove in the stem to a tubular balloon which fits over the receptor portion. Circumferential grooves are provided on the upper and lower sections of the receptor portion to accommodate rubber bands which secure a tubular gauze member over the balloon. The gauze member is expanded by inflation of the balloon .Iadd.during use.Iaddend.. The hollow interior of the stem provides a passage for endoscopic instruments such as forceps, dissectors, etc.

Claims

a balloon and a tubular gauze member surrounding the balloon at the lower portion of the central tube and having upper and lower elastic bands which mount in the respective circumferential tube grooves securing said balloon and gauze member in position, said balloon having an elongated inflation tube extending upwardly along the longitudinal groove to the upper portion of the stem cylinder, and wherein the balloon and gauze member include axial apertures through which the tube extends.

2. A spongestick for endoscopic procedures in accordance with claim 1 wherein:

the retractable sheath includes two handles, each extending outwardly on opposite sides of the sheath at its upper portion and the balloon inflation tube includes and upper portion having a Leur lock tip mounted thereto.

3. A spongestick for endoscopic procedures used in conjunction with endoscopic instruments comprising:

a rigid stem comprising an elongated hollow cylinder having upper and lower portions and internal and external cylinder walls for insertion of endoscopic instruments therethrough;

said hollow cylinder further comprising a solid portion and a hollow portion extending along the length thereof;

a retractable rigid sheath slidably mounted about the stem and having at least one handle projecting outwardly therefrom;

said lower portion having a concave recess within the solid portion of the external cylinder wall;

balloon means mounted about the lower portion of the stem within said recess; and

means for inflating said balloon means to protrude outwardly from said recess.

4. A spongestick in accordance with claim 3 and further comprising:

a groove extending longitudinally along the external cylinder wall extending from said recess to the upper portion of the stem, and said means for inflating said balloon means including an elongated inflation tube connected to said balloon means and positioned within the longitudinal groove of the stem and extending to the upper portion of the stem, wherein said hollow portion of the stem may be used for endoscopic procedures.

5. A spongestick in accordance with claim 3 wherein:

said stem further includes a pair of circumferentially spaced grooves about said lower portion of said cylinder, said balloon means comprising a balloon, a flexible gauze cover surrounding the balloon and means for securing ends of said balloon means within said circumferential grooves.

6. A spongestick for endoscopic procedures and used in conjunction with endoscopic instruments comprising:

a main hollow rigid stem comprising a cylinder having upper and lower portions and internal and external cylinder walls, said stem including a handle extending outwardly from said upper portion at an angle thereto and atleast two longitudinal grooves extending longitudinally along the internal cylinder wall thereof from the upper portion of the cylinder to the lower portion thereof; and

further including a solid elongated tube having upper and lower ends mounted within the cylinder and having an external wall and at least two longitudinal grooves extending along the external tube wall opposite the longitudinal cylinder grooves in the internal cylinder wall and forming passageways;

a lower member mounted adjacent the lower end of the tube having resilient means extending downwardly, and a fixed bottom platform, said resilient means connected between said lower member and said platform, and control wires mounted to the lower member and extending upwardly through the groove passageways and having an upper end extending outwardly therefrom; and

further comprising balloon means mounted about the resilient means between the lower member and the platform, said balloon means being expanded by activation of said control wires.

7. A spongestick in accordance with claim 6 further including:

a ring mounted to the upper end of the control wires and means on the upper end of the stem cylinder to engage the ring and lock the control wires in position with the balloon means expanded.

8. The method of endoscopically sponging a patient comprising the steps of:

providing an elongated sponging instrument for insertion into a patient, said instrument having .Iadd.a handle at one end .Iaddend.an interior stem .Iadd.extending outward from the handle .Iaddend.and an external sheath .Iadd.mounted about the stem.Iaddend.;

inserting a balloon over the stem of the instrument projecting from the sheath;

mounting a tubular gauze member over the balloon prior to inflation;

sliding the sheath over the gauze member, balloon and interior stem before insertion of the instrument into a body cavity;

inserting the sponging instrument into a body cavity in a patient;

retracting the sheath and inflating the balloon to expand the gauze for contact with the patient within the body cavity, and

manipulating the instrument with the handle and sheath to perform a sponging operation. .Iadd.

9. The method of retracting, and manipulating tissues and/or organs within a body cavity in an endoscopic procedure comprising the steps of:

providing an instrument comprising an elongated hollow stem surrounded by a retractable sheath for insertion into a body cavity and having a balloon mounted over one end of the stem and a gauze member mounted over the balloon in an uninflated condition;

sliding the end of the stem with the balloon and surrounding gauze member into the retractable sheath before insertion into a body cavity;

inserting the instrument into a body cavity with the balloon uninflated;

disengaging the sheath and said one end of the stem inflating the balloon to expand the gauze member within the body cavity; and

,

manipulating the instrument to perform a sponging operation;

said sponging operation comprising retraction and manipulation of the tissues or organs within the body cavity with the gauze member by movement of the stem. .Iaddend..Iadd.10. The method of retracting, and manipulating tissues and/or organs in accordance with claim 9 further including the step of;

inserting instruments through the hollow stem to perform surgical operations. .Iaddend..Iadd.11. The method of retracting, and manipulating tissues and/or organs in accordance with claim 9 further including the step of;

deflating the balloon and removing the instrument from the body cavity.

10. Iaddend..Iadd.12. A spongestick for manipulating, and retracting tissues and/or organs in endoscopic procedures within a body cavity used in conjunction with endoscopic instruments comprising:
