Bone tumor pathological specimen sampling adjustable fixator

Abstract

The invention relates to the technical field of bone tumors, and discloses a bone tumor pathological specimen sampling adjustable fixator. The device comprises a slide rail, and the right side of the slide rail is fixedly connected with a barrier strip; a long groove is integrally formed in the front surface of the sliding rail. The inner side wall of the long groove is slidably connected with a handle. The rear end of the handle is fixedly connected with a moving block; the moving block is located on the inner side wall of the sliding rail, and the moving block is in sliding connection with the sliding rail; the concave rail and a sliding rail are fixed to a vertical plate of a medical workbench, so that medical staff can hold a handle to slide, a movable block can move downwards, and the rotating wheels are located in the concave rail; when the movable block moves downwards, a transverse plate rotates, the transverse plate rotates with two rear rotating wheels as the circle center, a second round rod moves in a connecting plate; thereby, the rotating wheel at the rear part is also embedded in the concave track. According to the device, the transverse plate can be rotated to be in a vertical state, and the phenomenon that the occupied space of the device is large is reduced.

Description

technical field [0001] The invention relates to the technical field of bone tumors, in particular to an adjustable fixer for taking pathological specimens of bone tumors. Background technique [0002] Bone tumors are tumors that occur in the bone or its accessory tissues. There are benign and malignant. Benign bone tumors are easy to cure and have a good prognosis. Malignant bone tumors develop rapidly, have poor prognosis and high mortality. Secondary malignant bone tumors are secondary malignant tumors that metastasize from other tissues or organs in the body to bones through the blood circulation and lymphatic system. There is another type of lesion called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors. It is generally limited and easy to cure. [0003] The pathological report of bone tumors needs to be made through the pathological specimens of bone ...

Another type of lesion is called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors. It is generally limited and easy to cure

[0003] The pathological report of bone tumors needs to be made through the pathological specimens of bone tumors, so it is necessary to sample the patient's bones; since there are no special tools and the bones are very hard, it is difficult to obtain materials; at present, most of them are obtained by hand. When collecting materials, hold the bones in your hand and use hard objects, such as tabletops as support pads, which often lead to unstable fixation and inaccurate positioning, resulting in irregular sampling surfaces, which make it difficult to meet the sampling requirements, which in turn affects the quality of slices. analyze
