Abstract

The invention relates to the technical field of medical equipment, in particular to an adjustable curette, which comprises a handle and a curette head, the handle and the curette head are connected through an adjusting mechanism, the adjusting mechanism comprises a plurality of sets of longitudinal adjusting machines and connecting rods which are sequentially connected, and the connecting rods and the longitudinal adjusting mechanisms are connected through rotating mechanisms. The tail end of the connecting rod of the first adjusting mechanism is fixed to the head end of the handle, and the head end of the longitudinal adjusting mechanism of the tail adjusting mechanism is fixed to the tail end of the curette head. The handle and the curette head are connected through the adjusting mechanism by adjusting the rod part, so that the mobility of the curette head is improved, and the angle of the space in the medullary cavity is enlarged, so that the retention of infected tissues in the medullary cavity is reduced, and the recurrence rate of osteomyelitis is controlled.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an adjustable curette. Background technique [0002] The curette plays an important role in orthopedic surgery. It plays an important role in the removal of infection in the medullary cavity. However, due to the depth of the medullary cavity, it is impossible to look directly at it, and the existing curette shaft cannot be adjusted, so there is still a possibility of debridement in the medullary cavity. Blind spots, there are certain defects in the operation practice. Contents of the invention [0003] In order to overcome the deficiency of the existing curette adjustment ability, the present invention provides an adjustable curette. [0004] The technical solution adopted by the present invention to solve the technical problem is: an adjustable curette, including a handle and a curette head, the handle and the curette head are connected by an adjustment mechanism, a...
