The utility model relates to a
bone grafting instrument. The
bone grafting instrument comprises a
handle, an extension tube, a sealing cover and a storage bin for placing broken bones, the front end of the
handle protrudes from back to front to form a protruding part, the extension
pipe is communicated with the protruding part, and the sealing cover is in threaded connection with the end, away from the extension
pipe, of the
handle. According to the
bone grafting instrument, through the mechanical structure of the pushing rod and the pushing plate, broken bones can be rapidly and effectively pushed to the position between adjacent vertebrae from the storage bin, the operation efficiency is greatly improved, the
operation time and discomfort of a patient are reduced, the top plate and the closing
assembly are used in cooperation, the broken bones can be accurately controlled to be released in the pushing process, and the bone
grafting effect is improved. Compared with the prior art, excessive scattering or blocking of broken bones is avoided, the accuracy and the success rate of an operation are guaranteed, in addition, the storage bin is closed through the closing
assembly, the broken bones are effectively prevented from leaking in the pushing process, the clean and sterile state of an operation area is kept, and the
infection risk is reduced.
