Abstract
A bone gripping pincers for osteosynthetic purposes has a swivel joint (1) that can be locked, a minimum of two jaws (2, 3) and a minimum of two legs (4, 5). After bone fragments have been set by means of the bone gripping pincers, its swivel joint (1) can be locked, so that it can act as a permanent bone clamp. The legs (4, 5) can be removed. By a connection pin (9) mounted on the pincers, it is possible to combine several bone pincers into a stable osteosynthetic setting device.
Claims16
Pincers for gripping bones for surgical purposes comprising:
- at least two jaws;
- a lockable hinge pivotally joining said jaws to one another, said hinge constituting a swivel joint having a swivel pin component and a bore component, whereby said swivel pin component and said bore component are rotatively but not linearly movable with respect to each other;
- at least two legs, connected to said hinge for pivoting said jaws relative to one another;
- and
- a removable locking device at said hinge for fixing the pivotal positive of the swivel pin component and the bore component relative to one another.
Pincers for gripping bones for surgical purposes comprising:
- two jaws;
- a swivel joint connecting said jaws to one another, said swivel joint comprising a pin component and a bore component, said bore component being connected to one jaw and said pin component to another jaw, and said swivel pin component and said bore component each having two concentrically offset stops for limiting reciprocal rotation of said components;
- two legs, one connected to each of said pin and bore components for swinging said jaws about said swivel joint;
- and
- means at said swivel joint for locking said swivel joint to prevent swinging movement of said jaws.
Pincers for gripping bones for surgical purposes comprising:
- at least two jaws;
- a lockable hinge joining said jaws to one another, said hinge constituting a swivel joint having a swivel pin component and a bore component, said swivel pin component and said bore component each having two concentrically offset stops for limiting reciprocal rotation of said components;
- at least two legs, connected to said hinge for pivoting said jaws relative to one another;
- and
- a removable locking device for fixing the positions of the swivel pin component and the bore component relative to one another.
Pincers for gripping bones for surgical purposes comprising:
- at least two jaws;
- a lockable hinge joining said jaws to one another, said hinge constituting a swivel joint having a swivel pin component and a bore component, said swivel pin component having a central pin;
- at least two legs, connected to said hinge for pivoting said jaws relative to one another;
- a removable locking device for fixing the position of the swivel pin component and the bore component relative to one another;
- a connection pin;
- and
- an attachment device for locking the connection pin in any desired position, said connection pin being positioned to rotate on the central pin of the swivel pin component.
Pincers for gripping bones for surgical purposes comprising:
- at least two jaws;
- a lockable hinge pivotally joining said jaws to one another, said hinge constituting a swivel joint having a swivel pin component and a bore component, whereby said swivel pin component and said bore component are rotatively but not linearly movable with respect to each other;
- at least two legs connected to said hinge for pivoting said jaws relative to one another;
- and
- a removable locking device for compressing the swivel pin component and the bore component to fix the position of the jaws.
