Abstract
The utility model discloses a universal type intramedullary nail extractor which comprises an extracting rod. The circumference of the front outside of the extracting rod is full of little grooves, and the back end of the extracting rod is connected with a knocking device. The intramedullary nail extractor also comprises an assister bar hinged with the extracting rod, and the front end of the assister bar is also full of little grooves. As the use of the intramedullary nail extractor is not limited by the specifications of a screw hole of an intramedullary nail, the intramedullary nail extractor is suitable for intramedullary nails of various diameters of screwed holes, with excellent versatility and higher generalization and application value.
Description
Technical field
This utility model belongs to a kind of orthopedic medical device, particularly a kind of intramedullary nail extractor that is used to pull out intramedullary pin.
Background technology
In orthopaedics is clinical, the end that is used for the fixed intramedullary pin of orthopaedics has a screwed hole, when taking out intramedullary pin, generally be the end to be had with the bar of extracting of the corresponding screw thread of above-mentioned screwed hole screw in above-mentioned screwed hole, thereby with intramedullary pin with take out bar and connect as one, and then drag and extract bar intramedullary pin is taken out of.But in practical operation, above-mentioned screwed hole ratio is easier to damage and often makes that extracting bar can't connect, and the screwed hole specification of each producer's intramedullary pin and not quite identical now, and this just causes extracting bar can not be general, brought many puzzlements for actual the use.
Summary of the invention
The purpose of this utility model is with regard to being at the defective of above-mentioned prior art and provide a kind of versatility good and simple and practical universal intramedullary nail extractor.
Its technical solution is as follows: comprise that extracting this front end outer periphery of extracting bar of bar opens and be covered with tiny groove, the rear end of extracting bar connects knocking device, and this utility model comprises also and extract the hinged assister bar of bar that the front end of assister bar also is covered with tiny groove.
This utility model in use, a front end that only needs to extract bar probes in the screwed hole of intramedullary pin end, clamps intramedullary pin screw thread hole wall with assister bar and the front end of extracting bar, by knocking of knocking device intramedullary pin is extracted then.Use of the present utility model is not subjected to the restriction of the empty specification of intramedullary pin screw thread, and the intramedullary pin of applicable various tapped bores has excellent universality, possesses higher popularization and application values.
The utility model is described in further detail below in conjunction with accompanying drawing:
