Locking plate capable of accurately placing locking screw

Abstract

A locking plate capable of accurately placing a locking screw belongs to the technical field of orthopedic medical instruments and is used for accurately placing a locking screw when treating the fracture of limbs. According to the technical scheme: the locking screw hole of the locking plate is in a stepped shape; the upper part of the locking screw hole is a protective sleeve groove; the middlepart of the locking screw hole is a drill sleeve groove; the lower part of the locking screw hole is a screw hole; a thread is arranged on the circumferential walls of the protective sleeve groove andthe drill sleeve groove; the soft tissue protective sleeve is a steel sleeve, the outer wall of the lower part of the soft tissue protective sleeve is provided with a thread matched with the thread on the inner wall of the protective sleeve groove, a thread matched with thread on the inner wall of the drill sleeve groove is arranged on the outer wall of the drill sleeve, and the diameter of the inner hole of the drill sleeve is matched with the diameter of the screw hole of the locking screw hole. The device solves the problems of inaccurate position, difficult placement, long operation timeand easy to damage surrounding soft tissue when a prior locking plate is used for placing the locking screw, after a hole is drilled, the locking screw can be directly screwed in through the soft tissue protective sleeve, thereby providing technical support for minimally invasive resetting.

Description

technical field [0001] The invention relates to a locking bone plate for treating limb fractures, belonging to the technical field of orthopedic medical devices. Background technique [0002] The locking plate is a fracture fixation device with locking threaded holes, which can ensure that the screw and bone plate are integrated through the locking threaded holes to achieve angular stabilization. The use of locking plates to fix fractures is a common method for clinical treatment of extremity fractures. In actual clinical application, because the soft tissue such as muscle at the fracture site is relatively rich and dense, the traditional locking bone plate often removes the drill sleeve when inserting the screw, resulting in inaccurate screw placement, difficulty in placement, and waste of operation time, which can seriously lead to Internal fixation failed. With the evolution of fracture treatment concept and the development of clinical treatment technology, the traditio...

Problems solved by technology

In actual clinical application, because the soft tissue such as muscle at the fracture site is relatively rich and dense, the traditional locking bone plate often removes the drill sleeve when inserting the screw, resulting in inaccurate screw placement, difficulty in placement, and waste of operation time, which can seriously lead to Internal fixation failure

With the evolution of fracture treatment concept and the development of clinical treatment technology, the traditional locking bone plate can no longer meet the needs of clinical treatment. The current development trend of locking bone plate is to combine with minimally invasive technology as much as possible to effectively protect the soft tissue around the fracture. Realize minimally invasive reduction, so designing a new locking bone plate will provide necessary and indispensable technical support for the development of new technology
