Abstract
The utility model relates to a medical tool, in particular to a remote-hole positioning device, used in fracture surgery, comprising a handle, a positioning main rod (5) connected with the handle (1), and a remote positioning support (7) mounted at the remote end of the positioning main rod (5) and arranged with a height ruler (6). The utility model is characterized in that the positioning main rod (5) is further arranged with a positioning connecting rod (3) which front end is connected with the near hole of an intramedullary nail, the positioning main rod (5) is mounted with a limiter (4), the front end of the positioning connecting rod (3) is provided with screw and the near hole of the intramedullary nail (2) is provided with an internal screw, which are connected via screws, the limiter (4) is a limit pin relative to a ring of groove at the middle of the positioning connecting rod (3). The utility model has the advantages that the utility model can accurately find the position of remote locking hole of intramedullary nail, to make surgery simple, reduce surgery time and avoid accidence.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of far-end nail hole positioning device is used for bone surgery.
Background technology
At present, the localizer remote stomidium of the intramedullary nail with lock of Shi Yonging location owes accurate clinically, main cause is that the distance that intramedullary pin swings with main locating rod in the operation changes, height gauge can not accurately be pushed up thereon, cause locating hole on locking of intramedullary nail and the main locating rod, thereby often cause the boring failure not on same plane, need change into boring under the X-ray again, both prolong operating time, increased operating difficulty, and also can influence surgical effect.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the shortcoming that exists in the prior art, a kind of position that can accurately determine the intra medullary nail far-end locking nail hole is provided, makes the far-end nail hole positioning device that operation is simple and convenient, avoid unnecessary damage.
This utility model is achieved in that a kind of far-end nail hole positioning device for this reason, comprise handle, the location mobile jib that links together with handle and be installed in the far-end locating rack that location mobile jib far-end which is provided with height gauge, also be provided with the positioning linkage rod that front end is connected with intramedullary pin near-end nail hole on the mobile jib of location, be equipped with on the mobile jib of location and limit the stopping means that positioning linkage rod moves forward and backward, the front end of positioning linkage rod is threaded, intramedullary pin near-end nail pore area has female thread, the two is by being threaded, stopping means be one with the corresponding spacer pin of a circle groove at positioning linkage rod middle part.
The beneficial effects of the utility model are: can accurately determine the position of intra medullary nail far-end locking nail hole, make operation simple and convenient, shorten operating time, avoid unnecessary damage.
