Description

Kirschner wire bending and tail rotating device

Technical Field

The utility model relates to the technical field of orthopedic surgical tools, in particular to a Kirschner wire bending and tail screwing device.

Background

As is well known, kirschner wire is a commonly used internal fixation material for orthopaedics, the original specification length of the internal fixation material is generally fixed at about twenty centimeters, the diameter of the internal fixation material is between 0.5 and 2 millimeters, and the internal fixation material has different specifications. The device is used for fixing fracture parts with low stress such as short fracture or avulsion fracture, and is also commonly used for temporary fixation of fracture blocks in bone surgery. The maximum diameter of the k-wire gradually increases to 4 mm due to the wide application. With the use of external fixation brackets, the external fixation locking nails are often matched to fix larger fractures such as pelvic fracture, calcaneus fracture and the like.

In particular use, the kirschner wire is driven into and fixed to the bone, and then the kirschner wire is required to be bent, and subsequent operations, such as cutting to a proper length and adjusting the tail direction, are performed after the bending. At present, when the Kirschner wire is bent, related instruments are basically needed to be utilized, but the existing Kirschner wire bending instruments, such as a novel Kirschner wire bending device disclosed in patent No. CN214678994U, can meet the clamping and bending requirements of the Kirschner wire, but find the following defects in clinical use: first: the diameters of blind holes at two ends of the instrument are fixed, namely, kirschner wires with different diameters are matched with instruments with different types; the depth of blind holes at two ends is limited, namely, the Kirschner wire can be inserted and bent after being cut short. Second,: the whole instrument is in one direction, and when the instrument is bent, the operation is easily blocked by surrounding soft tissues, so that the Kirschner wire is not bent to a proper angle; and the sight of an operator is easy to be blocked, which is unfavorable for accurate bending. Third,: after the Kirschner wire is bent and the tail end length is cut, other instruments are needed to be replaced to adjust the tail end direction of the Kirschner wire.
