Abstract
The utility model relates to a femur neck thread needle navigator, which comprises a soleplate, an upright column and a handle, wherein one end of the upright column is fixedly connected to the soleplate, the other end of the upright column is fixedly connected with the handle, and a fixed needle positioning passage is arranged between the soleplate and the upright column. The utility model is characterized in that an extended hole of a navigating needle passage is arranged on the soleplate, the navigating needle passage is arranged at the extended hole, and a universal adjusting mechanism is arranged on the navigating needle passage. Because the utility model is provided with the fixed needle passage and the universal adjusting navigating needle passage, the femur neck thread needle navigator effectively solves the problems of a directional thread needle position, a reference object position and a three-dimensional position. The utility model has the advantages of precise navigation, convenient and reliable operation, simple structure, low manufacture cost, etc.
Description
This utility model belongs to the orthopaedic medical treatment operating theater instruments.
Fracture of femoral neck and intertrochanteric fracture of the femur are very common clinically a kind of damages, and wherein majority needs carry out various operative treatments by the neck of femur technology of threading a needle.The neck of femur method of threading a needle commonly used both at home and abroad at present has following several: (1) direct-view method: open joint capsule, expose femoral head, cervical region, thread a needle under the direct-view.The shortcoming of this method is that operation wound is big, and hemorrhage many, operating time is long, and it is slow that postoperative function recovers, and complication is many.(2) empirical method: do not expose femoral head, cervical region, aim at the hip joint center by rule of thumb and thread a needle.The shortcoming of this method is that the location is rough, and the mortality height of threading a needle is threaded a needle repeatedly and can be caused the operating time prolongation, damages and increase the weight of.(3) localizer auxiliary law: carry out orientation by various locating apparatus and thread a needle.But existing various neck of femur locating apparatus all has following shortcoming: 1. be single needle track location, lack reference with fixing; 2. be the two-dimensional directional location, lack accuracy.
The purpose of this utility model is exactly the shortcoming that overcomes prior art, provides a kind of and can be neck of femur thread a needle precision navigation (three-dimensional localization) and Femoral Neck Needle Penetration Navigator simple in structure, low cost of manufacture.
This utility model comprises base plate, column, handle, one end of column is fixed on the base plate, the other end is connected with handle, the stationary positioned needle track is housed between base plate and column, be characterized in having on the base plate navigation needle track and stretch out the hole, be provided with the navigation needle track at this place, hole, on the navigation needle track universal adjustment mechanism be housed.
As further improvement of the utility model, described universal adjustment mechanism comprises that its vertical protractor that is provided with the longitudinal oscillation bar and its are provided with the transversal vector hornwork of teeter bar, there is a protractor connecting rod that two protractors are linked as integral body, one end of this protractor connecting rod is affixed with the housing of vertical protractor, the other end and teeter bar are affixed, described longitudinal oscillation bar connects with the navigation needle track by navigation needle track fixed arm, and transversal vector hornwork throughput hornwork fixed arm is fixed on the column.It is the little down big conical bore of that described navigation needle track stretches out the hole.
But this utility model is owing to be provided with a fixedly navigation needle track of needle track and universal adjustment, efficiently solve the location that orientation threads a needle and the problem of object of reference and three-dimensional localization, have advantages such as accurate, easy and simple to handle reliable, simple in structure, the low cost of manufacture of navigation.
Below in conjunction with description of drawings this utility model is further described below:
Fig. 1 is a perspective view of the present utility model.
As shown in Figure 1, it comprises base plate 1, column 2, handle 3 this utility model, one end of column 2 is fixed on the base plate 1, the other end is connected with handle 3, between base plate 1 and column 2, stationary positioned needle track 4 is housed, be characterized in having on the base plate 1 the navigation needle track and stretch out hole 5, be provided with navigation needle track 6, on the navigation needle track 6 universal adjustment mechanism is housed at this place, hole.Described universal adjustment mechanism comprises that its vertical protractor that is provided with longitudinal oscillation bar 89 and its are provided with the transversal vector hornwork 12 of teeter bar 11, there is a protractor connecting rod 10 that two protractors are linked as integral body, one end of this protractor connecting rod 10 is affixed with the housing of vertical protractor 9, the other end and teeter bar 11 are affixed, described longitudinal oscillation bar 8 connects with navigation needle track 6 by navigation needle track fixed arm 7, and transversal vector hornwork 12 throughput hornwork fixed arms 13 are fixed on the column 2.It is the little down big conical bore of that described navigation needle track stretches out hole 5.
