Quick attachment clamp for external fixation systems

Abstract

A clamp (1) for an external fixator, preferably of the quick attachment type, comprising: at least one first attachment (2) provided with at least one bar housing seat (26) for a bar of the external fixator and / or with at least one screw housing seat (23a, 23b) for a bone screw; at least one second attachment (3) provided with at least one bar housing seat (36); a connector (5) which, in a tightened configuration, passes through said first attachment (2) and said second attachment (3) locking the bars and / or bone screws within the bar housing seats (26, 36) and / or the screw housing seats (23a, 23b); and which, in an open configuration, frees the entrance to at least the bar housing seat (36) of said second attachment (3); and auxiliary connection means (4) between said first attachment (2) and said second attachment (3) which are active in said open configuration.

Description

Technical field [0001] The present invention relates to a clamp for orthopedic applications, in particular intended for coupling elements constituting an external fixation system. [0002] The present invention therefore in orthopedic surgery, in particular surgery trauma art found useful application. Background technique [0003] In orthopedics, commonly used for stabilizing bone segments and reduce the external fixation and manipulation. These techniques provide surgical applications rigid exoskeleton, in its simplest form consists of a set of rods, the set of rods hinged to each other by means of a suitable fixture, the set screws and bone structure by means of a lever associated with the patient. The mechanical system generally employed is called an external fixator. [0004] Diversity as a reality of hospital treatment demand has led to differences in the different types of holders, each holder has technical and morphological characteristics suitable for its intended to be u...

AI Technical Summary

Problems solved by technology

Therefore, lateral insertion proves to be a complex operation and requires considerable time spent by the surgeon during the procedure

[0010] The second disadvantage is usually caused by the need to disassemble the unit in some applications

This manipulation does carry the risk of dropping and / or losing individual parts, which is a particularly critical risk when disassembly must be performed during surgical procedures

[0011] A third disadvantage is that the weight of the retainer consists of the sum of the rod and the clamp, mainly due to the type of material employed

[0012] Another disadvantage is due to the large number of parts that make up the fixture, which leads to high manufacturing costs of the assembly
