Description

Gun type osteomyelitis curet

Technical Field

The utility model relates to the technical field of osteomyelitis surgery, in particular to a gun type osteomyelitis curette.

Background

Osteomyelitis is an infection and destruction of bone, and can be caused by aerobic or anaerobic bacteria, mycobacteria, and fungi. Osteomyelitis occurs well in long bones, in the feet of diabetics or in penetrating bone lesions due to trauma or surgery. The most common site in children is the metaphysis of well-supplied long bones, such as the tibia or femur. Surgical debridement is currently the most common treatment. Thorough debridement of the lesions is a key step in osteomyelitis surgery.

The traditional osteomyelitis operation mode is to open a window to thoroughly debride lesion infected tissues, but because a medullary cavity is of a tubular structure and the window opening range cannot be too large, the bone strength is affected, and fracture is easy to occur after the operation. In a limited windowing range, due to improper angles, the focuses in the medullary cavity are difficult to completely and completely clear through a curette, partial focuses are easy to remain, and the recurrence after the osteomyelitis operation can be possibly caused.
