Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of structure simple, the Interlocked intramedullary-nail fitting instrument that distal stent can be general.
This utility model solves the technical scheme that its technical problem adopts: a kind of Interlocked intramedullary-nail fitting instrument, for distal locking nail being aimed at the distal locking nail hole of interlocking intramedullary nail, comprise handle, arc mark post and distal stent, described handle is U-shaped, handle side is installed with interlocking intramedullary nail near-end and is connected, and handle opposite side is installed with arc mark post and is connected;
Described arc mark post has the equidirectional crooked radian with interlocking intramedullary nail, and described arc mark post side is provided with multiple for installing with handle the location hole be connected, and arc mark post opposite side is provided with distal side face;
Connection distal side, described distal stent one end face, the described distal stent other end is connected to the far-end of interlocking intramedullary nail by locating rod.
Further, described distal stent offers the registration holes of distal locking nail being aimed at distal locking nail hole on interlocking intramedullary nail, registration holes, distal side face and distal locking nail hole are arranged on same straight line.
Further, described intramedullary interlocking nail distal end is provided with locating hole, and locating rod arranges perpendicular to interlocking intramedullary nail and inserts locating hole.
Further, described distal locking nail hole is positioned at locating hole both sides.
The beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, when applicable spike system, owing to adopting arc mark post, arc mark post has the equidirectional crooked radian with interlocking intramedullary nail, and the distance thus between the far-end of arc mark post and intramedullary interlocking nail distal end can not produce variation, just do not need the distal stent that configuration is new in addition, distal stent can be general, can not cause the wasting of resources, reduces cost.
