Abstract
The utility model discloses a novel intramedullary nail extractor which comprises a support rod and a V-shaped support rod. Two support rods are hinged together; thin grooves are fully formed on the circumference of the outer sides of the front ends of the support rods; and a striking device is connected with the tail end of the support rod. The utility model has the advantages that the operation is not restricted by the specifications of intramedullary nail screw holes; the good commonality and the popularization and application value are ensured, and the utility model is adaptable to intramedullary nail with various screw hole diameters.
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, intramedullary pin is right taking out, 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 novel intramedullary nail extractor.
Its technical solution is as follows: comprise straight strut and V-brace, two struts are articulated as one and the front end outer periphery of two struts is opened and is covered with tiny groove, and wherein straight strut rear end connects knocking device.
This utility model only needs the front end of two struts is probeed in the screwed hole of intramedullary pin end in use, by articulated structure the simultaneously outside support of front end of two struts is against on the intramedullary pin screw thread hole wall simultaneously, 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:
Description of drawings
Figure is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, this utility model comprises that straight strut 1 and V-brace 2, two struts are articulated as one and the front end outer periphery of two struts is opened and is covered with tiny groove, and wherein straight strut 1 rear end connects knocking device.
During use, the front end of two struts 1 and 2 is probeed in the screwed hole 4 of intramedullary pin 3 ends, the front end that makes two struts by articulated structure simultaneously outwards support be against simultaneously on the intramedullary pin screw thread hole wall, by knocking of knocking device intramedullary pin is extracted then.
