Description

Technical Field

[0001] This utility model relates to the field of bone crusher technology, specifically an electric bone crusher. Background Technology

[0002] Medical bone fragment crushers, as the name suggests, break bone into very small fragments. The size of these fragments is suitable for use, and they are primarily used as fillers between bones during surgery. Currently, bone fragments are commonly used in spinal fusion surgeries. The spine is composed of different vertebrae connected by intervertebral discs in front and two facet joints behind. These joints allow the spine to bend and twist. With age or after trauma, these joints may wear down or degenerate, leading to pain. In such cases, medication or surgery is needed to stabilize the affected areas of the spine. If physical and drug treatments cannot control the pain, surgery is required. However, the stability established by various internal fixations is only temporary. Over time, their fixation effect will gradually weaken, and the stability they provide will be lost. This necessitates spinal fusion surgery to achieve permanent stability. In spinal fusion surgery, bone fragments taken from other parts of the patient are broken up and used to fill and support the spaces between adjacent vertebrae, aiming to achieve healing and relief for the patient.

[0003] Traditionally, bone fragments used in surgery are either cut into appropriately sized pieces using surgical scissors and forceps, which is time-consuming, inefficient, produces uneven bone fragments, and results in poor surgical outcomes; or they are cut using hand-cranked bone fragment breakers, which is laborious. Therefore, an electric bone fragment breaker has been proposed. Utility Model Content
