Bone tumor biopsy puncture needle

Abstract

The invention discloses a bone tumor biopsy puncture needle. The bone tumor biopsy puncture needle comprises a bone puncture device, a first electric retractor, an electric rotating device and a splayed base, wherein the bone puncture device is connected to the bottom of the first electric retractor; the upper end of the first electric retractor is fixedly connected to the left side of the bottom of the electric rotating device; the electric rotating device is fixedly connected to the bottom of the base; the right side of the bottom of the electric rotating device is fixedly connected with a second electric retractor, and a second high-definition video camera is arranged at the bottom of a connecting rod; the side edge of the base is connected with a monitoring control device. Through the cooperation of the monitoring control device, the electric retractors and the electric rotating device and the unique structure of the puncture and biopsy acquiring device, a biopsy material can be accurately punctured and accurately grasped, the operation success rate is improved, and the pain of patients is reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a bone tumor biopsy puncture needle. Background technique [0002] Bone tumor is a tumor that occurs in bone or its accessory tissues, and is a common clinical disease. The only way to obtain pathological examination materials before operation is biopsy. Therefore, under the premise of ensuring safety, it is very important to obtain as many specimens as possible to improve the accuracy of biopsy diagnosis. At present, the biggest problem with bone biopsy is that the specimen tissue obtained is too large. Few, one-sided, can not be accurately diagnosed, or even misdiagnosed, the reason for the lack of biopsy tissue is: the tissue cutting structure of the biopsy puncture needle is generally groove-shaped, and the groove is too small; or barb-shaped, unable to hook enough pathological Tissue, another important reason is that most of them are manually operated, relying on the experien...

Few, one-sided, can not be accurately diagnosed, or even misdiagnosed, the reason for the lack of biopsy tissue is: the tissue cutting structure of the biopsy needle is generally groove-shaped, and the groove is too small; or it is barb-shaped, which cannot hook out enough pathological Tissue, and another important reason is that most of them are manually operated, relying on the experience of doctors, but different doctors have different methods and techniques, resulting in different puncture errors
