Abstract
Disclosed is an intramedullary positioning guide device for neck of femur osteotomy used for artificial coxa displacement operation. The direction of a medullary cavity of the device is determined by an intramedullary positioning rod; the intramedullary positioning rod is connected with a connecting rod casing through a connecting rod vertical to the intramedullary positioning rod; the connecting rod and the connecting rod casing are both squares, and the connecting rod casing can slide on the connecting rod. The connecting rod casing is provided with a round connecting rod vertical to the connecting rod casing; the round connecting rod is in the same direction with the intramedullary positioning rod. The round connecting rod is connected with a connector through a connecting hole on the connector; the connector can slide and rotate on the round connecting rod. The connector is connected with an osteotomy guide through a connector fixing rod and a connector fixing bolt in the lower part of the connector; the osteotomy guide is provided with an osteotomy guide hole; the direction of osteotomy is controlled by making use of the osteotomy guide hole on the osteotomy guide device, and in this way, a precise and objective osteotomy surface whose angle meets the requirement of the prosthesis can be obtained.
Description
Affiliated technical field
Utility model relates to a kind of guider that carries out the neck of femur osteotomy when being used for artificial hip joint replacing, can accurately control the direction of osteotomy, makes osteotomy surface and femoral prosthesis reach good fit.
Background technology
At present, when artificial hip joint replacing was performed the operation, the neck of femur osteotomy adopted the outer die trial of marrow to determine sagittal angle, and the angle on the cross section does not have a kind of accurate, objective guider then by operator's subjective judgment.During osteotomy the inaccuracy of angle and and the objective foundation of neither one, the osteotomy surface of neck of femur can not be complementary with femoral prosthesis, cause the proximal part prosthese can not place in the femur prosthese neck neck and osteotomy surface can not matched well, form the some contact and make stress concentration, stress distribution is unreasonable between whole prosthese and femur, influencing the stable of prosthese, is an assignable cause of prosthetic loosening.The installation of prosthese can not reach designing requirement, and the service life of prosthese shortens relatively.The coupling that solves osteotomy surface and femoral prosthesis near-end and neck neck is the starting point of this new design.
Summary of the invention
In order to overcome the deficiency that present neck of femur osteotomy osteotomy surface can not reach matched well with prosthese, improve the service life of artificial hip joint, this utility model provides a kind of location and guider, makes the neck of femur osteotomy more accurate, objective, realizes the matched well of neck of femur osteotomy surface and prosthese.
This utility model technical scheme that is adopted of dealing with problems is: the direction of determining pulp cavity with locating rod in the marrow, in the marrow locating rod by with marrow in the vertical connecting rod of locating rod be connected with the connecting rod overcoat, connecting rod and connecting rod overcoat are square, and the connecting rod overcoat can slide on connecting rod; Connecting rod has put outward and the vertical circular connecting rod of connecting rod overcoat, and circular connecting rod is identical with locating rod direction in the marrow; Circular connecting rod is connected with adapter by the connecting hole on the adapter, adapter can slide on circular connecting rod and rotate, adapter is connected with the osteotomy guider with the adapter set bolt by the adapter fixed bar of adapter below, the osteotomy pilot hole is arranged on the osteotomy guider, utilize the direction of the osteotomy pilot hole control osteotomy on the osteotomy guider.When operation technique, appear neck of femur pears shape nest, pierce to the pulp cavity direction with drill bit, and expand marrow with the pulp cavity expander, select locating rod insertion pulp cavity in the corresponding marrow according to the thickness of pulp cavity, determine the medullary cavity y direction, pass through connecting rod, adapter is connected with the osteotomy guider, and guider can slide on the connecting rod y direction, adjusts the direction and the guider of connecting rod, determine to want the in-plane of osteotomy, carry out osteotomy with goose saw by the osteotomy pilot hole on the osteotomy guider during osteotomy, the direction of pilot hole control goose saw saw blade so just can obtain one accurately, objective, angle meets the osteotomy surface of prosthese requirement.
The beneficial effects of the utility model are that locate mode is objective rationally, connects reliable, can control the angle of osteotomy surface in use effectively, make osteotomy surface and femoral prosthesis matched well, stress rationally conducts, thereby reduce the prosthetic loosening that physical factor causes, improve prosthese service life.
