SU635979A1 - Device for bone osteotomy - Google Patents

Description

The invention relates to the field of medicine and is intended for the production of bone osteotomy in surgical treatment methods. A device for osteotomy of bones is known, which contains a chisel, a handle with working jaws and a guide l. A disadvantage of the known device is that it does not allow dosing the depth to the lot in the bone, which causes significant tissue trauma. The aim of the invention is to eliminate the traumatization of underlying tissues, vessels and nerves during bone osteotomy. The goal is achieved by the fact that the device is equipped with limiters made in the form of sliders mounted on guides and spindle screws, with the guides being positioned on the handle with the ability to move by means of bolts, the handle provided with an emphasis, and . FIG. 1 shows a bone osteotomy device} in FIG. 2 - the same, side view; in fig. 3 is a view along arrow A of FIG. 1. The device has a handle 1 connected to bits 2 by means of limiter 3, guide 4 and bolts 5. Limiter 3 and guide 4 have adjusting sliders 6 and lead screws 7. One of the bits has a longitudinal groove 8. Moreover, handle 1 has an emphasis 9 in the form of a prism and a graduated scale 10. The device operates as follows. For osteotomy, a device without bits is placed under the bone section of the bone, so that 5shore 9 covers the bone, and notches on the stop allow it to be fixed tightly. Set the specified distance between the bits using the spindle screws 7, guide 4 and limiter 3. The depth of the bit in the bone is set using limiter 3 on the graduated scale 10. Put the handle 4 and the limiter 3 with bits 2 on the handle 1. In the osteotomy process When striking the bits 2, the stop 9 is pressed tightly against the bone by the handle 1, thereby creating a counter-stop. The proposed design of the device allows to produce segmental

bone osteotomy with adjustable depth and distance between the osteotomy lines. The presence of an adjustable limiter in the device ensures reliable protection of the underlying tissues, vessels and nerves during osteotomy of bones of any diameter. The device is compact and can be used for osteotomy of bones of various locations.
