Description

Tibial transverse bone moving osteotome

Technical Field

The utility model relates to the technical field of orthopedic medical equipment, in particular to a tibial transverse bone moving osteotomy device.

Background

The principle of transverse tibial bone migration mainly comes from a physiological phenomenon discovered by Ilizaloff. This doctor has found that by pulling cortical bone, or by performing some osteotomy of the bone and pulling, blood vessels, nerves and other soft tissue structures within the body grow. Even if there is no obvious attachment relationship, after such osteotomy and distraction, the peripheral growth factors, such as vascular endothelial growth factor, increase significantly, and promote the repair of the peripheral soft tissue. Therefore, based on the principle, after the transverse tibial bone transfer operation is performed, the blood circulation reconstruction of the lower limb can be promoted in the process. Therefore, the operation is widely applied to vascular diseases of lower limbs, such as thromboangiitis obliterans, diabetic feet and the like. By performing a lateral tibial bone transfer operation, the time for which the operation is maintained is about one month, and the blood circulation of the lower limb is reestablished during this period, and then the blood circulation is restored, so that the symptoms caused by poor blood circulation can be rapidly restored.

When the tibia is moved transversely to treat the diabetic foot, the tibia needs to be cut by a osteotome, the operation time is long, and uneven conditions are easy to occur in the cut bone cutting block, so that the bone, periosteum and bone marrow are damaged; after improvement, a circle of small holes can be punched on the tibia along the rectangular frame body by using a drill, and the section of the tibia is cut off by using the external fixing frame, so that the tibia is time-consuming and labor-consuming.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a horizontal bone of shin bone that structural design is reasonable, the simple operation, punch more corresponding, practice thrift operation time, optimize the operation step moves and cuts bone ware.

The utility model discloses the horizontal bone of shin bone is moved and is cut bone ware, cut bone ware include rectangular frame body 1, rectangular frame body 1 bottom border wherein a set of symmetry border is provided with sawtooth 3, rectangular frame body 1's border surface is provided with through-hole 2.

The distance between the through holes 2 is 0.5-0.8 cm.

The utility model has the advantages that:

1) the bottom edge of the rectangular frame body 1 is provided with saw teeth 3 along one group of symmetrical edges, the surface of the edge of the rectangular frame body 1 is provided with a through hole 2, in the transverse tibia bone moving operation, the inner side of the middle section of the shank of an affected limb is incised, subcutaneous tissues are separated to periosteum, the periosteum is incised longitudinally and retracted towards two sides, an osteotome is attached to the surface of a bone needing osteotomy operation, a Kirschner wire penetrates through a through hole 2 arranged on the surface of the edge of a rectangular frame body 1 to drill the surface of the bone, so that the osteotomy process is more targeted, the surgical site is more accurately positioned, the surgery time of a doctor is saved, after the perforation on the surface of the bone is finished, the bone knife is used for perforating all the drilled holes, the perforated bone blocks are taken down, the whole osteotomy operation can be completed, time and labor are saved, doctor-patient time is saved, the pain of a patient is relieved, sclerotin, periosteum and bone marrow are effectively protected, and secondary injury is reduced; in the process of cutting the bone, the bone cutter can be fixed on the surface of the bone through the saw teeth 3 arranged at the bottom of the rectangular frame body 1, the fixation is safe and firm, the bone cutter can be prevented from being fixed by hands for a long time in the operation process of a doctor, the labor is saved, and the bone cutting efficiency is improved.

2) The utility model has the advantages of simple structure and reasonable design, can solve the horizontal bone of shin bone and move the fixed problem of osteotome ware in the operation, simplify the operation step, greatly practice thrift doctor operating time, more do benefit to the patient, consequently be worth popularizing and applying.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a sectional view a-a of fig. 1.

In the figure: rectangular frame 1, through-hole 2, sawtooth 3.

Detailed Description

The present invention will be further explained with reference to fig. 1 and 2.

The utility model discloses constitute by rectangle framework 1, through-hole 2, sawtooth 3, specific structure is: the osteotomy device comprises a rectangular frame body 1, wherein sawteeth 3 are arranged on one group of symmetrical edges of the bottom edge of the rectangular frame body 1, and through holes 2 are arranged on the surface of the edge of the rectangular frame body 1. The distance between the through holes 2 is 0.5-0.8 cm, the distance between the through holes 2 is more beneficial to drilling holes by using a bone knife, and time and labor are saved.

The size of the bone window for moving is determined according to the size of the patient, the size of the bone window is about 8-10cm in length and 1.5-2cm in width when the height is less than 160cm, so that the length of the rectangular frame body 1 is 8-10cm, and the width is 1.5-2 cm; the size of the bone window with the height of 160-170cm is about 10cm, and the width is 2cm, so that the length of the rectangular frame body 1 is 10cm, and the width is 2 cm; the size of the bone window is about 11cm and 2cm when the height is 170 and 180cm, and the length of the rectangular frame body 1 is 11cm and the width is 2 cm; the size of the bone window is about 12cm and 2cm above 180cm of height, and the length of the rectangular frame body 1 is 12cm and the width is 2 cm. Other desired specifications may also be set.

The operation of transverse tibial bone shift is suitable for diabetic foot, thromboangiitis obliterans, ischemic lower limb diseases, etc. The arc incision is taken from the inner side of the middle section of the lower leg of the affected limb about 12cm in length in the operation process, subcutaneous tissues are separated from periosteum and the periosteum is protected, the periosteum is longitudinally cut and is retracted towards two sides, the osteotome is attached to the bone surface needing osteotomy operation, the bone surface can be fixed at the bottom of the rectangular frame body 1 through the saw teeth 3 arranged at the bottom of the rectangular frame body 1, the osteotome is fixed on the bone surface, a Kirschner wire penetrates through the through hole 2 formed in the edge surface of the rectangular frame body 1 to drill the bone surface, the osteotome is more targeted in the osteotome process, the surgical position is more accurately positioned, the operation time of a doctor is saved, after the perforation of the bone surface is finished, all drill holes are drilled through by a bone knife, the punched bone blocks are taken down, the whole osteotome operation can be completed, other.
