Abstract
A surgical instrument assembly for making a shunt passage between the oesophagus and the surface of the neck, for accommodating a larynx prosthesis. The assembly includes a curved puncture needle, a prosthesis place holder and a placing needle, and optionally includes a tracheostoma template. The bent configuration of the puncture needle ensures correct formation of the shunt passage. The prosthesis place holder allows the shunt passage to heal up in the correct configuration. The placing needle provides for correct fitting and radiological checking of the place holder.
Claims19
A surgical instrument assembly for making a cavity for receiving a larynx prosthesis, comprising:
- a curved puncture needle,
- said needle having a tip at one end, a curved central portion and a gripping means at the other end;
- a prosthesis place holder,
- said place holder comprising an elastomer having a main cylindrical body portion, a compressible securing portion disposed thereon, and a guide passage extending within said main body portion and being accessible from the exterior through an opening, and
- a placing needle,
- said placing needle having a rounded end portion, a curved shank portion and a grip means at the other end.
A method for making a cavity in a patient's throat for receiving a larynx prosthesis therein, comprising the steps of:
- forming a curved puncture in said patient's throat by puncturing said throat with a curved puncture needle;
- said needle having a tip at one end, a curved central portion and a gripping means opposite said one end;
- and
- securing a prosthesis place holder in said curved throat puncture;
- said place holder comprising an elastomer having a main cylindrical body portion, a compressible securing portion disposed thereon, and a guide passage extending within said main body portion and being accessible from the exterior through an opening therein;
- wherein said securing step is carried out by:
- (a) engaging said place holder with a placing needle, said placing needle comprising a rounded end portion, a curved shank portion and a grip means opposite said rounded end portion;
- (b) placing said engaged placing needle and place holder in said curved throat puncture;
- and (c) disengaging said placing needle from said place holder, and withdrawing said placing needle from said throat puncture.
