Definitions
- the instrument has a shaft leading from the instrument head to a handle and a milling cutter shaft which runs in or on the shaft, this shaft with the milling cutter shaft being opposite the Axis of rotation of the instrument head is angled.
- This allows the instrument to be brought to the acetabulum from a direction that does not coincide with the acetabular axis.
- the acetabular axis is considered to be the straight line leading through the center of the acetabular sphere and perpendicularly through the opening plane of the acetabulum.
- the instrument can be guided from the side to the acetabulum, it is possible to choose a minimally invasive, lateral access to the acetabulum, for example an anterolateral or postolateral access.
- the angle of the shaft with respect to the axis of rotation of the instrument head is expediently between 90 and 135 degrees, measured on the side facing the milling cutter. This angle is expediently unchangeable in the interest of the simple design of the instrument. However, it can also be adjustable and fixable in a desired position or freely variable so that the doctor can optimally adapt the direction of the handle during milling to the respective conditions.
- the instrument head can be brought in from the side through a narrow surgical opening, its dimension in the direction of the milling cutter axis should be as small as possible.
- the distance between the point of intersection of the axis of rotation of the instrument head with the axis of the shaft or the drive axis on the one hand and the center of the instrument head on the other hand is as small as possible. It should not be larger than the cutter diameter and preferably half the cutter diameter.
- the outer dimension of the instru- ment head should not be larger than 8 cm, preferably not larger than 6 cm.
- a guide device which transfers the alignment of the femoral neck to the instrument. This is based on the knowledge that the direction of the femoral neck in many cases gives an accurate indication of the desired alignment of the milling cutter. In any case, this applies when the ligamentous apparatus, which is largely preserved in a minimally invasive mode of operation, is still in a normal condition and the surgeon ensures that the leg assumes a natural position. In order to transmit the direction of the femoral neck to the instrument according to the invention, this has an attachment part on the side remote from the instrument head, which is oriented in the same direction as the femoral neck.
- the attachment part is formed by a pin which extends in the direction of the axis of rotation of the milling cutter and which cooperates appropriately with a bore which the surgeon has previously made in the femoral neck from the resection surface.
- This pin can be fixedly connected to a housing part of the milling cutter. It can also be formed by a continuation of the cutter shaft and rotate with the cutter. In this case, it is expedient if a bushing that can be inserted into the bore of the femoral neck is provided for receiving the pin.
- the housing parts 1, 2 of the instrument head 3 are firmly connected to a shaft 4, which forms a handle 15 and contains a drive shaft 5, the free end 6 of which can be connected in a known manner to a drive motor or a handle for manual drive.
- the drive shaft 5 carries a pinion 7 inside the housing 1, 2.
- a cutter shaft 8 is also rotatably mounted transversely to the drive shaft 5.
- the angle between the two shafts is expediently between 90 and 135 °.
- the cutter shaft carries a bevel gear 9, the teeth of which mesh with those of the pinion 7. In this way, the milling cutter shaft 8 can be driven in rotation by the drive shaft 5.
- gear for example a worm gear
- the gear itself or a card portion connected to it can be designed to be angle-tolerant in order to adjust the angle between waves 5 and 8.
- a fixing device can be provided which allows the instrument to be locked in the selected angle setting. Instead, free angular mobility can also be provided.
- a hemispherical milling tool 10, known as such, is interchangeably placed on the end of the milling cutter shaft 8, which is referred to in this description as a milling cutter for the sake of simplicity.
- the milling cutter has moved close to the housing 1, 2 of the instrument head.
- the distance of the center point 22 of the milling cutter - more generally, the center of its rear face - from the crossing point 21 of the axes of the shafts 5 and 8 is less than the radius of the milling cutter, preferably less than a quarter of the milling cutter diameter. If the milling cutter is not hemispherical, the largest diameter takes the place of the mentioned diameter.
- a pin 11 protrudes, which is fixed, possibly in one piece, connected to the milling cutter shaft 8 and has a common axis of rotation 12 with it.
- a sleeve 13 with end flange 14 is fitted onto the pin 11 with a sliding fit.
- the instrument is used in the following way. After the femoral head has been removed, a blind bore is made in the femoral neck from the resection surface thereof, into which the sleeve 13 is inserted. The leg is positioned normally so that the neck of the femur faces the acetabulum. The instrument is inserted so that the pin 11 in the Fe- in the sleeve bore 13 is inserted. The cutter 10 is pressed into the acetabulum by the ligaments holding the proximal femur and at the same time is aligned in a natural way. The milling of the acetabulum can now be carried out with little or no help from the surgeon. The operation is then continued in a known manner.
- FIG. 1 While the exemplary embodiment according to FIG. 1 is satisfied with a handle shaft projecting transversely from the instrument head 3, an instrument is schematically indicated in FIG. 2, the handle 15 'of which is arranged approximately in the axis 12 of the milling cutter 10, the shaft 4' of the instrument guides perpendicular to the instrument head 3 'and at the end carries a drive motor 16.
- the end of the shaft 4' is rigidly connected to the handle 15 'by a bracket 17'. Its position shows the operator exactly the position of the milling cutter axis 12 and allows him not only to align the milling cutter according to the desired axial direction, but also to control the force with which the milling cutter is pressed into the acetabulum.
