Abstract

Disclosed is a soluble suturing device for an intestine, which includes a suturing receptor, a staple receiver and a suturing presser, each of which is formed of a material to be solubilized by an intestinal juice and shaped in the form of a cylindrical body having an outer diameter insertable into an intestine. The suturing receptor, at its rear end, is provided with a suitable number of receiving seats located circumferentially therein each having a staple-receiving groove and formed of a rigod material, while the staple receiver, at its front end, abuts the rear end of the suturing receptor and is provided with a corresponding number of staple-holding apertures, each arranged for holding a staple at a position corresponding to the staple-receiving groove of the seat. The suturing presser is provided with a staple-urging plate for urging the staple in each of the staple-holding apertures toward the staple-receiving groove.

Claims

1. A soluble suturing device for an intestine, comprising:

(a) a staple receiver-magazine means for temporarily receiving a plurality of staples, a suturing presser means for pressing staples out of said magazine means and inserting said staples into the material of a human or animal body, and a suturing receptor means for deforming the ends of inserted staples;

(b) each of said suturing receptor means, said staple receiver means and said suturing presser means being made of a material soluble in an intestinal juice;

(c) each of said suturing receptor means, said staple receiver means and said suturing presser means being shaped in the form of a cylindrical body, each cylindrical body having a predetermined diameter and being insertable into an intestine;

(d) said suturing receptor means comprising a rear end and a front end, said rear end comprising a circumference including a plurality of receiving seats positioned therein;

(e) each of said receiving seats comprising a staple receiving groove, each said receiving groove being made of a rigid material;

(f) said staple receiver means comprising a front end and a rear end, said front end of said staple receiver means abutting said rear end of said suturing receptor means; and

(g) said front end of said staple receiver means comprising a plurality of staple-holding apertures, each of said staple-holding apertures comprising means for holding a staple at a position corresponding to a respective staple-receiving groove of said receiving seat.

2. The soluble suturing device for an intestine as claimed in claim 1, wherein said suturing presser means comprises at least one staple-urging plate for urging at least one said staple in one of said staple-holding apertures toward one said staple-receiving groove.

3. The soluble suturing device for an intestine as claimed in claim 1, wherein said soluble material is selected from the group consisting of naturally occurring polymeric material, cellulose derivates and synthetic polymers.

4. The soluble suturing device for an intestine as claimed in claim 2, wherein each of said suturing receptor means, said staple receiver means and said suturing means comprises a thin coating of a partially soluble polymeric material on respective external surfaces thereof for delaying solubilization of said suturing receptor means, said staple receiver means and said suturing presser means in said intestine.

5. The soluble suturing device for an intestine as claimed in claim 4, wherein said polymeric material is selected from the group consisting of ethylcellulose and cellulose acetate.

6. The soluble suturing device for an intestine as claimed in claim 2, wherein said intestinal juice is water.

7. The soluble suturing device for an intestine as claimed in claim 1, wherein said soluble material is a naturally occurring polymeric material.

8. The soluble suturing device for an intestine as claimed in claim 1, wherein said soluble material is a synthetic polymer.

9. A soluble suturing device for an intestine, comprising means for receiving and deforming the ends of a plurality of staples, means for temporarily holding a plurality of staples adapted to be inserted and engaged into said receiving and deforming means, means for pressing said staples out of said holding means into said receiving and deforming means, wherein said receiving and deforming means, said staple holding means, and said staple pressing means each is formed of a material soluble in an intestinal juice.

10. The soluble suturing device for an intestine as claimed in claim 9, wherein said receiving and deforming means comprises a suturing receptor, said suturing receptor being shaped in the form of a cylindrical body having a predetermined diameter and being insertable into an intestine.

11. The soluble suturing device for an intestine as claimed in claim 10, wherein said material is selected from the group consisting of naturally occurring polymeric material, cellulose derivatives and synthetic polymers.

12. The soluble suturing device for an intestine as claimed in claim 9, wherein said stable holding means comprises a staple receiver, said staple receiver being shaped in the form of a cylindrical body having a predetermined diameter and being insertable into an intestine.

13. The soluble suturing device as claimed in claim 12, wherein said material is selected from the group consisting of naturally occuring polymeric material, cellulose derivatives and synthetic polymers.

14. The soluble suturing device for an intestine as claimed in claim 9, wherein said staple pressing means comprises a suturing presser, said suturing presser being shaped in the form of a cylindrical body having a predetermined diameter and being insertable into an intestine.

15. The soluble suturing device for an intestine, as claimed in claim 14, wherein said suturing presser comprises at least one staple-urging plate for urging at least one staple in said holding means.

16. The soluble suturing device as claimed in claim 14, wherein said material is selected from the group consisting of naturally occuring polymeric material, cellulose derivatives and synthetic polymers.

17. The soluble suturing device for an intestine, as claimed in claim 9, wherein each of said receiving and deforming means, said staple holding means, and said staple pressing means comprises a thin coating of a sparingly soluble polymeric material on exterior surface thereof for delaying solubilization of said receiving and deforming means, said stable holding means and said staple pressing means.

18. The soluble suturing device for an intestine as claimed in claim 17, wherein said polymeric material is selected from the group consisting of ethylcellulose and cellulose acetate.

19. The soluble suturing device for an intestine as claimed in claim 9, wherein said soluble material is water.

20. The soluble suturing device for an intestine as claimed in claim 9, wherein said soluble material is a naturally occurring polymeric material.

21. The soluble suturing device for an intestine as claimed in claim 9, wherein said soluble material is a synthetic polymer.

22. A method for suturing first and second severed portions of an intestine, comprising the steps of:

(a) inserting a front end of a suturing receptor having a guide cylinder into said first severed portion of said intestine such that a portion of said guide cylinder is protruding externally from said first severed portion of said intestine;

(b) covering said portion of said guide cylinder with a staple receiver and a suturing presser, said suturing presser comprising a plurality of staple-urging plates located at front end thereof, said staple receiver comprising a plurality of staple holding apertures, each of said staple holding apertures corresponding to a respective staple urging plate of said suturing presser;

(c) inserting said second severed portion of said intestine onto said suturing presser and said staple receiver;

(d) stretching mucous membranes of said first and second severed portions of said intestine;

(e) pressing a rear end of said suturing presser toward said suturing receptor thereby inserting said staple-urging plates into said staple holding apertures of said staple receiver;

(f) pushing staples located in said staple holding apertures into said staple receptor thereby suturing said intestine; and

(g) dissolving said suturing receptor, said staple receiver and said suturing presser in an intestinal juice after a predetermined interval.
