Abstract

The invention discloses a multi-functional skeleton drilling-grinding bone harvester. The multi-functional skeleton drilling-grinding bone harvester comprises a handle, a sleeve, a drill rod, a drillbit and a measuring device. One end of the sleeve is provided with a fixing cover, and the other end of the sleeve is provided with a locking groove. The drill rod passes through the fixing cover. Oneend of the drill rod is provided with the handle, and the other end of the drill rod is provided with the drill bit. The outer side face of the sleeve is provided with the measuring device. The sidewall of the sleeve is connected with a searchlight. 4-6 LED lamp sources are installed around the searchlight. The multi-functional skeleton drilling-grinding bone harvester is strong in practicability, simpler in operation, and capable of rapidly and accurately taking caput femoris, and accurately measuring a size of the caput femoris, thereby reducing operation wound and haemorrhage. A whole design has the characteristics of firmness and durability, simple and convenient operation, and low cost, and is capable of taking out a whole bone, conveniently measuring a diameter of the taken bone, and reducing the operation injury.

Description

technical field [0001] The invention relates to a medical device, in particular to a drill and bone extractor. Background technique [0002] Lumbar intervertebral disc herniation is a common and frequently-occurring disease in spinal orthopedics. It is due to the degeneration of the intervertebral disc, the rupture of the annulus fibrosus, and the protrusion of the nucleus pulposus to the spinal canal, which stimulates and compresses nerve roots, blood vessels or spinal cord. Symptoms such as numbness. Patients often suffer from severe pain and cannot walk, which seriously affects their life. Traditional surgical treatment involves large trauma, heavy bleeding, slow postoperative recovery, and there are adverse reactions such as long-term postoperative waist discomfort and high recurrence rate. With the popularity of the minimally invasive concept, the drilling and grinding bone harvester came into being. Contents of the invention [0003] Purpose of the invention: The ...
