System to be used with an implanting tool

Abstract

A system to be used with an implanting tool having a tip part. The system has a longitudinal axis and includes a polymeric screw having a head and an adapter between the screw and the implanting tool. The adapter includes a first part that fits the tip part of the implanting tool.

1 . A system to be used with a surgical implanting tool having a tip part, the system having a longitudinal axis, the system comprising:
 an adapter comprising a first part which fits the tip part of the implanting tool, the first part being concentric with the longitudinal axis of the system, the first part comprising a first element which comprises fingers;   a polymeric screw having a head, the polymeric screw being concentric with the longitudinal axis of the system, the head of the polymeric screw comprising a second element, the second element comprising cutting-ins on the outer periphery of the head of the polymeric screw; and   the fingers and the cutting-ins form counterparts.   
   
   
       2 . The system according to  claim 1 , wherein the shape of the first element and the second element is such that the maximum torque in the screwing-in direction is substantially the same as in the screwing-off direction. 
   
   
       3 . The system according to  claim 1 , wherein the first part is compatible with the implanting tool according to ISO 5835. 
   
   
       4 . The system according to  claim 1 , wherein the head of the first part comprises a recess which is hexagonal, cruciform, hexalobular, quadratic, or the recess is a single slot. 
   
   
       5 . The system according to  claim 1 , wherein the adapter comprises metal. 
   
   
       6 . The system according to  claim 1 , wherein the polymeric screw is bioabsorbable. 
   
   
       7 . The system according to  claim 1 , wherein the first part of the adapter is connectable to the screw by either a female connection or a male connection.
