Abstract
In order to perform an anastomosis, a pilot head of a surgical staple suturing instrument is connected through a push-type or a threaded connector and through a paraboloid-like cap so as to simplify introduction into the organ that is to be anastomised. The combination body is pushed through the organ with the help of a probe, as far as the end of the organ that has been sutured with a purse-string suture. Once the desired position of the pilot head is reached, the cap is released and then removed. The pilot head is then connected with the end of the journal of the staple suturing instrument through the push-type or threaded connector.
Claims33
A staple suturing instrument for performing an anastomosis, said instrument comprising:
- a staple magazine including a central journal and a circular scalpel, a pilot head releasably secured at an end of the central journal, said pilot head having an hemispherical outer surface and an anvil surface for clinching staples, said anvil surface facing the staple magazine, wherein the pilot head is releasably attached through a connector with the end of the central journal and with a cap that covers the anvil surface and the connector wherein said cap has a curved outer surface.
A method for performing an anastomosis by the introduction of a surgical staple suturing instrument having a central journal into an organ that is to be anastomised, said method of comprising:
- (a) providing a purse-string suture at the organ end to be joined, (b) folding the end of the organ about a staple magazine, (c) providing a purse-string suture at the free end of the other organ that is to be anastomised, (d) folding the other organ end about a hemispherical pilot heat that has a staple cinching surface that is connected to the staple magazine through a journal, (e) connecting the pilot head with a cap having a convex surface that covers the staple cinching surface, (f) introducing the pilot head and cap into the second organ in the direction of the free end that has the purse-string suture, and independently of the staple magazine that is connected with the staple suturing instrument that is introduced a desired distance into the first organ that is to be anastomised, (g) removing the cap from the pilot head, (h) connecting the pilot head to the central journal of the staple suturing instrument, and (i) effecting a stapled joint of both organ ends by pressing the pilot head onto the staple magazine.
A stapling head for a staple suturing instrument for performing an anastomois, said instrument comprising:
- a staple magazine including a central journal and a circular scalpel, a pilot head releasably secured at an end of the central journal, said pilot head having an hemispherical outer surface and an anvil surface for clinching staples, said anvil surface facing the staple magazine, wherein the stapling head is constructed in two parts, and wherein the pilot head is connectable with the end of the central journal and with a cap having a curved outer surface that covers the anvil surface.
