Tissue cutting clamp apparatus

Hand manipulable tissue cutting apparatus formed in a scissors like configuration comprising:

• a first clamp member and a second clamp member with first and second respective laws in opposing facing interoperative relation for clamping said tissue, with said clamp members pivotably coupled;
• an elongate generally planar blade having a cutting edge at one end thereof;
• sheath means on at least one of said clamp members for receiving said blade for movement therethrough to displace said cutting edge alone a given plane generally perpendicular to said opposing face of said jaw of said at least one clamp member from a first position with said cutting edge in non-interference with said jaws to a second position overlying said jaws;
• said blade includes guide means and said at least one clamp member has a guide channel formed therein for receiving said guide means and cooperating with said guide means for controlling movement of said blade along said given plane;
• said at least one clamp member further includes latch means for releasably engaging said blade in said first position;
• and
• the other of said clamp members includes sheath means adjacent the jaw thereof, said sheath means of both said clamp members providing guide rail portions along the outside edges of both said jaws for passage of the blade therein with said jaws in the closed position.

• said blade includes guide means and said at least one clamp member has a guide channel formed therein for receiving said guide means and cooperating with said guide means for controlling movement of said blade along said given plane;
• said at least one clamp member further includes latch means for releasably engaging said blade in said first position;
• and
• said blade includes detent means formed in a side edge thereof and said latch means includes a spring biased projection for engaging said detent means with said blade in said first position and a portion overlying the upper surface of said at least one clamp member providing means for opposing said spring bias to manually release said blade from said detent.

• a first clamp member and a second clamp member with first and second respective jaws in opposing facing interoperative relation for clamping said tissue, with said clamp members being pivotably coupled;
• an elongate generally planar blade having a cutting edge at one end thereof;
• first sheath means on said first clamp member for receiving said blade for movement therethrough to displace said cutting edge along a given plane generally perpendicular to the plane of the mating faces of said jaws from a first position with said cutting edge in non-interference with said jaws to a second position overlying said jaws;
• and
• said second clamp member includes second sheath means adjacent the jaw thereof, said first and second sheath means providing cooperating guide rail portions along the outside edges of both said jaws for passage of the blade therein with said jaws in the closed position.
