Description

Proximal femoral osteosynthesis tool guide

The utility model relates to the field of medicine, namely to orthopedics and traumatology.

Known apparatus spoke-drill-guide, used in surgical treatment of juvenile epiphysiolysis of the femoral head. / Invention and rationalization in pediatric traumatology and orthopedics (collection of scientific papers). - Leningrad, 1976 - from. 102-104./. The device consists of a guide with a hole for holding a drill and several holes for holding knitting needles. The angle of the guide is fixed on a graduated scale, which is installed on the base.

However, the design of this device does not allow its use

together with a chisel - a guide for osteotomy of the proximal section

the femur. In addition, this device is screwed to the bone during surgery, while the operation time is increased, the accuracy of the operation depends on the initial strengthening of the guide on the bone.

The objective of the technical solution is to create an easy-to-use tool guide with the possibility of using it in the surgical treatment of deformations of the proximal end of the femur.

The task is achieved in that the tool guide contains two bars connected by a hinge and a graduated scale. The latch bar is the reference, and the upper is the guide rail, it has channels for holding the spokes. The upper surface of the upper bar is the guide for the bit. The graduated scale serves simultaneously as a fixer of the installation angle of the upper bar, a limiter for lateral mobility of the bit and a handle for holding.

The lower plate has a small thickness and can be inserted into the depth of the wound, while its lower surface has supporting elements of the corresponding configuration for reliable retention on the bone.

Figure 1 shows a view of the device from left, right, front and top. Nodral channels on the upper bar 2 of different sizes, are used to hold spokes of different diameters with the task of setting the exact angle. Their configuration and the presence of restrictive screws allows the needles to be carried out both without a jig and with a jig.

The figure shows the use of a protractor with a spear-shaped bit 4. The lateral mobility of the bit 4 is limited by the heads of the limit screws 3 and the graduated scale 5.

The lower surface of the support bar serves to fix it on bones of different diameters. The small thickness of the support bar allows it to lead into the depth of the wound and stably install on the bone. The graduated plate 5 is used to set a specific angle, the locking screw 6 fixes the specified angle. The graduated plate is made with a serrated edge, for example, with a step of five degrees, which allows you to reliably fix a given angle with a locking screw 6 and reliably hold the entire structure during surgical treatment. Collapsible design, the configuration of the longitudinal guide channels will allow high-quality pre-sterilization treatment.

Claims (1)

The guide of the proximal femur osteosynthesis tool consists of two bars and a graduated scale fixed on the lower plate, the lower surface of the latter provides a stable position on the bone surface, the upper plate is movable, fixed at the required angle, its upper surface serves as a guide for the bit, in addition, on it there are channels for holding knitting needles of different diameters, also the bar is equipped with two restrictive screws, the heads of which, together with the graduated scale, limit the shackle chisel mobility.
