Built-in bone tumor pathological tissue extraction device

Abstract

The invention discloses a built-in bone tumor pathological tissue extraction device, which comprises a positioning frame, an assembling carrier plate, a penetrating nail barrel and a drawing main pipe, wherein the cross section of the main body of the positioning frame is of a "circular-ring-shaped" structure, and a positioning structure is fixedly arranged at the top of the positioning frame; the assembling carrier plate is fixedly arranged over the main body of the positioning frame, and a transmission structure is fixedly arranged on the inner side of the assembling carrier plate; the penetrating nail barrel is fixedly arranged on the inner side of the transmission structure, a locking structure is fixedly arranged on the inner side of the penetrating nail barrel, and a stabilizing structure is fixedly arranged on the inner side of the penetrating nail barrel; and the drawing main pipe is fixedly arranged on the inner side of the penetrating nail barrel. A tapping screw can bring convenience to the penetrating nail barrel to be quickly drilled into a diseased bone, and the penetrating nail barrel can be locked into the diseased bone; and multiple groups of drawing open pores can facilitate follow-up sampling of diseased tissues and can avoid the situation that the follow-up sampling of the diseased tissues by the device is affected due to blocking of a single drawing open pore, and then, the overall practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of surgical auxiliary medical devices, in particular to a built-in bone tumor pathological tissue extraction device. 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. Malignant bone tumors are divided into primary and secondary. 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. Another type of lesion is called tumor-like lesion. The tissue of tumor-like lesion 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. When treating bone tumors, Tissue sampl...

Problems solved by technology

[0006] The purpose of the present invention is to provide a built-in bone tumor pathological tissue extraction device to solve the problem that the existing bone tumor pathological tissue extraction device proposed in the background technology has a single structure. The traditional method of sampling through bone tissue puncture requires medical personnel to carry out the process by hand. Operating with a handheld device, the existing bone tumor pathological tissue extraction device is less stable, which may easily lead to errors such as deviation of the puncture position and inaccurate depth, and is prone to additional damage to the patient, and is likely to lead to Contamination of healthy parts
