RU87346U1 - GUIDELINES FOR THE INSTALLATION OF A SPINCULAR FIXATOR FOR THE OPERATIVE TREATMENT OF MEDIAL FEMORAL FRACTURES - Google Patents

Abstract

A guide for installing a spoke screw retainer, characterized in that it consists of a tubular guide casing, a guide washer for drilling the cortical bone layer, a guide for knitting needles with longitudinal grooves and a screw cannulated rod for fixing the lock washer.

Description

The utility model relates to medicine, namely to traumatology and orthopedics, and can be used in surgical treatment of medial femoral neck fractures.

To install only V-shaped knitting needles, a laparoscopic guide is used (Lazarev A.F., Solod E.I. However, this guide cannot be used to mount the V-shaped spokes with a locking washer.

The technical result of the utility model is to reduce the morbidity and reduce the duration of surgery.

The technical result is achieved due to the fact that the guide consists of a tubular casing of the guide, a guide washer for drilling the cortical layer of bone, a guide for knitting needles and a screw lock of the washer. The utility model is illustrated by the figures:

Figure 1 shows a General view of the guide in section.

Figure 2 - installation of V-shaped spokes with a guide.

The guide for installing the fixing washer and V-shaped knitting needles consists of (Fig. 1) a tubular casing 1 (Fig. 1), a guide for knitting needles with longitudinal grooves 2 (Fig. 1), a guiding washer for drilling channels in the cortical part of the bone 3 ( figure 1), a cannulated rod for fixing the washer 4 (figure 1). The locking washer 5 (figure 1) is installed in the tubular casing using a cannulated rod 4 (figure 1). Through the holes 6 (FIG. 1) in the guide washer 3 (FIG. 1) and the fixing washer 5 (FIG. 1), channels are drilled in the cortical part of the undervert region. The direction of the holes of the guide washer 3 (Fig. 1) exactly coincides with the holes of the fixing washer of the implant 5 (Fig. 1) After removing the washer 3 (Fig. 1), V-shaped spokes 1 (Fig. 1) are inserted into the guide for the spokes 2 (Fig. 1) .2). Pusher 3 (figure 2) needles are embedded in the bone tissue of the femoral neck. Using a cannulated screwdriver, the rod 4 (Fig. 1) is unscrewed and the guide for the spokes 2 (Fig. 1) is removed. On repositional spoke through the casing 1 (figure 1) is installed fully retaining washer for V-shaped spokes.

Thus, the proposed device differs from the similar one in that it consists of a tubular guide casing, a guide washer for drilling the cortical bone layer, a guide for knitting needles and a screw lock of the washer.

Using the proposed device can reduce the time and morbidity of surgical intervention.
