Instrument and associated method for applying biologically effective composition during laparoscopic operation

A surgical method comprising the steps of:

• providing a trocar, a trocar sleeve and a laparoscopic instrument including a deformable cup-shaped receptacle at a distal end of an elongate shaft;
• further providing a biologically active composition in said receptacle;
• using said trocar to form a perforation in an external body surface of a patient;
• disposing said trocar sleeve in said perforation;
• inserting said elongate shaft, with said composition disposed in said receptacle, through said trocar sleeve so that a distal end of said instrument protrudes into a body cavity of the patient while a proximal end of said instrument remains outside said patient;
• manipulating said proximal end of said instrument, from outside the patient, to place said cup-shaped receptacle into contact with a tissue surface inside said body cavity and to deform said receptacle so as to press said composition onto said tissue surface;
• removing said receptacle from said tissue surface;
• upon removal of said receptacle from said tissue surface, reforming said receptacle to resume its cup shape;
• and
• maintaining at least a portion of said composition in a deposit on said tissue surface upon removal of said receptacle from said tissue surface.

A surgical method comprising the steps of:

• providing a trocar, a trocar sleeve and a laparoscopic instrument including a roller at a distal end of an elongate shaft;
• using said trocar to form a perforation in an abdominal wall of a patient;
• disposing said trocar sleeve in said perforation;
• inserting said elongate shaft, with said roller, through said trocar sleeve so that a distal end of said instrument protrudes into an abdominal cavity of the patient while a proximal end of said instrument remains outside said patient;
• manipulating said proximal end of said instrument, from outside the patient, to place said roller into contact with a biologically active composition on a tissue surface inside said abdominal cavity;
• and
• further manipulating said proximal end of said instrument, from outside the patient, to roll said roller along said tissue surface to spread said composition along said tissue surface.

A laparoscopic instrument comprising:

• an elongate shaft having a distal end and a proximal end;
• means on said shaft at least at said distal end thereof for applying a biologically active composition to a tissue surface inside a patient during a laparoscopic procedure;
• a fiber optic laser beam transmission guide extending along said shaft from said proximal end to said distal end;
• and
• a laser source operatively connected to said guide at said proximal end of said shaft for generating a laser beam for transmission through said guide upon application of said biologically active composition to said tissue surface during said laparoscopic procedure,
• said means for applying including flexible receptacle means attached to said shaft at said distal end thereof for temporarily storing a predetermined amount of said biologically active composition and for deforming in response to a pressing of said shaft, to deposit said biologically active composition onto said tissue surface.

A laparoscopic instrument comprising:

• an elongate substantially rigid shaft having a distal end and a proximal end;
• means on said shaft at least at said distal end thereof for applying a biologically active composition to a tissue surface inside a patient during a laparoscopic procedure, said means for applying including a roller rotatably mounted to said shaft at said distal end thereof;
• a fiber optic laser beam transmission guide extending along said shaft from said proximal end to said distal end;
• and
• a laser source operatively connected to said guide at said proximal end of said shaft for generating a laser beam for transmission through said guide upon application of said biologically active composition to said tissue surface during said laparoscopic procedure.

• said means for applying including a longitudinally extending channel extending along said shaft, an applicator brush in said channel and a duct extending along said shaft in parallel with said channel, said means for applying also including feeder means for feeding said biologically active composition through said duct to a distal end portion of said channel, whereby said applicator element can engage said biologically active composition to apply said biologically active composition to a surface inside the patient.
