Abstract

Use in traumatology and orthopedics for conducting wire saws during femur surgery. SUMMARY OF THE INVENTION: The device comprises a handle with a casing bent under the femur and a working part made in the form of pivotally connected links with a threaded tensioning mechanism and a groove for wire saw 8 or

Description

This invention relates to medicine, namely surgery.

The purpose of the invention is to reduce trauma due to the additional expansion of the surrounding soft tissues.

FIG. 1 shows the device, a general view; Fig. 2 shows a threaded tensioning mechanism; in fig. 3 - an element of the device in the working position in FIG. 4 - a handle with washers; Fig 5-rod, Fig 6-casing with a chute; FIG. 7 shows the working part; FIG. 8 - the device is in working position.

The device comprises a handle 1 with a curved working part 2 with a groove 3 for a wire saw 4.

The handle 1 is provided with a sleeve 5 with a square hole 6 and a casing 7 with a groove 8 curved under the femur. The working part 2 is made in the form of pivotally connected links 9 and is equipped with a hook 10, a threaded tension mechanism 11 and an additional groove 12 in which a cable 13 fixed at one end on the link 9 of the working part 2 and the other on the tension mechanism 11, while the working part 2 is fixed on the rod 14 of square section, which is installed in the sleeve 5 with the possibility of longitudinal movement. Handle 1 is connected to the sleeve th 5 with a thread, and the working part 2 is adapted to interact with the chute 8 of the casing 7

The device is used as follows.

After exposing the bone area to the osteotomy to be performed, the working part 2 of the device is placed under it. When rotating the sleeve 5, the casing 6 moves with the chute 8 along the rod 14 in the longitudinal direction, which releases the working part 2 from the casing 6 with the chute 8 with the wire saw 4 located in the internal groove 3

Wire saw 4 removed from hook 10

When the tension mechanism 11 is rotated, which has a connection with the working part 2: the configuration of the links 9 changes, due to which the working part straightens the edges

wounds and thereby ensure the production of the main moment of the operation and protect soft tissues from injury when cutting 4 bones with a wire saw.

The proposed design provides additional expansion of the surrounding soft tissues, which reduces injuries and frees up the additional hands of the assistant.
