Biopsy puncture needle for orthopedics department

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a biopsy puncture needle for orthopedics department, which comprises a puncture needle mechanism and an auxiliary mechanism. The puncture needle mechanism and the auxiliary mechanism are arranged, in the puncture process, due to the fact that the handheld end is attached to the skin all the time, support is provided for medical staff, guide is provided for the puncture needle tube, and then the puncture needle tube is more stable in the puncture process; meanwhile, due to the fact that the puncture needle tube is always wrapped by the protective tube and the human tissue in the using process, the puncture needle tube cannot be exposed in the air, accidental injury of the puncture needle tube to the human body can be effectively reduced, and meanwhile the puncture needle mechanism is separated from the auxiliary mechanism, and the puncture needle tube is not in contact with the auxiliary mechanism; and the proportion of disposable articles can be effectively reduced, so that the auxiliary mechanism can be continuously recycled, and the use cost of the biopsy puncture needle for the orthopedics department is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a biopsy puncture needle for orthopedics. Background technique [0002] Most of the orthopedic biopsy puncture needles in the prior art are disposable, so in order to save costs, their structure is relatively simple. During the process, the stability of the arm of the medical staff is highly required. When the arm of the medical staff shakes, it is easy to cause the puncture needle to move off-axis, which in turn increases the diameter of the wound formed by the puncture needle and increases the injury to the patient. In order to ensure the stability of the arm, the personnel need to spend more effort, resulting in more laborious puncture work. At the same time, the puncture needle is exposed to the air during the process of opening the package and removing the protective cover. Its sharp structure is easy to cause harm to the human body. Accidental injury, there is a ce...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the structure of the existing puncture needle is too simple, which requires high stability of the arm of the medical staff during the puncture process. When the arm of the medical staff shakes, it is easy to cause the puncture needle to move off-axis. Furthermore, the diameter of the wound formed by the puncture needle becomes larger, and the injury to the patient increases. At the same time, in order to ensure the stability of the arm, the medical staff need to spend more effort, which leads to the problem that the puncture work is more laborious. The present invention proposes an orthopedic biopsy needle
