Abstract

The invention discloses a novel device for obtaining pathological materials of femoral head whole bone, which relates to the technical field of medical devices, comprising a first arc-shaped embracing device with a cavity, one side of the cavity with a first arc-shaped groove, and a first arc-shaped groove. A first guide hole is provided at the bottom of the arc-shaped groove; a matching second arc-shaped embracing device is slidably connected in the cavity, and a second arc-shaped embracing device matching the first arc-shaped groove is provided inside the second arc-shaped embracing device. The bottom of the second arc-shaped groove is provided with a second guide hole matching the first guide hole, and an adjustment hole is provided on the outer wall of the other side of the cavity, and an adjustment rod is provided in the adjustment hole, and the adjustment rod passes through the adjustment hole It is detachably connected with the second arc-shaped embracing device; the top of the first arc-shaped embracing device is provided with a bone drill navigation device, and a matching cutting device is provided in the bone drill navigation device. The invention can shorten the time for obtaining materials of the full-thickness bone tissue of the femoral head, and provide corresponding guarantee for the subsequent relevant molecular biology experiments.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for obtaining pathological materials from femoral head whole bone. Background technique [0002] At present, femoral head necrosis is a common clinical disease. In order to complete relevant scientific research, it is necessary to collect clinical samples of femoral head (cartilage, cortical bone, cancellous bone) for subsequent protein / nucleic acid extraction and micro-CT scanning under sterile conditions. Or staining of pathological sections. [0003] The conventional method for obtaining pathological materials of the femoral head is manual fixation with rongeur combined with cutting with an oscillating saw, fixation with rongeurs, and sampling with an oscillating saw or spatula, that is, the surgeon uses the rongeur to clamp the femoral head with one hand , and the other hand uses the orthopedic oscillating saw to cut the femoral head or scrapes the bone with...
