Description
Technical Field
The invention relates to the field of medical equipment, in particular to a markable puncture needle assembly.
Background
The puncture needle is a diagnosis and treatment device which is used for puncturing the inside of a human body, extracting secretion from a body cavity for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting medicine into the body cavity. The puncture needle is often used with a needle cylinder, when in use, the puncture needle is inserted into the needle cylinder, a needle head penetrates out of the needle cylinder, and then the puncture needle and the needle cylinder are punctured into the human body together, so that the needle cylinder can effectively expand tissues around the puncture position of the puncture needle.
In order to avoid damage to internal nerves and tissues of a human body by puncture, the angle and the depth of the puncture needle penetrating into the human body must strictly follow the preset regulations, but the existing puncture needle is difficult to quickly and accurately position after entering the human body, so that the operation time is prolonged, and the operation difficulty is increased, so that the positioning problem when the puncture needle is used is always puzzled to medical staff.
The existing puncture needle positioning method mainly comprises ultrasonic positioning, magnetic resonance positioning and X-ray developing positioning. The images obtained by the ultrasonic positioning method are quite fuzzy, and the position of the puncture needle cannot be accurately positioned. For example, patent application No. CN101040790 discloses a puncture needle comprising a tubular outer cylinder needle having a blade at the tip and an inner needle inserted and combined into the inner cavity of the outer cylinder needle, wherein the outer circumference of the region from the blade to the base end of the outer cylinder needle is formed with a concave processing, and the outer circumference of the region from the tip to the base end of the inner needle is formed with a rough processing. When the puncture needle punctures the body under the observation of the ultrasonic diagnostic device, a clearer reflected wave detection image detected by the ultrasonic diagnostic device can be obtained until the blade tip of the puncture needle. However, the outer periphery of the region from the distal end to the proximal end of the inner needle of the puncture needle is roughened, which not only affects the accuracy of the puncture needle when it is inserted into the human body, but also increases the possibility of displacement of the puncture needle and the pain of the patient.
When the magnetic resonance positioning method is used for imaging, the puncture needle made of metal materials can generate artifacts, and the positioning precision of the puncture needle is influenced. For example, the patent with the publication number of CN101773404 discloses a magnetic resonance puncture needle, which comprises an outer needle and an inner needle embedded in the outer needle; the outer needle comprises an outer needle handle and an outer sleeve needle connected with the outer needle handle, the inner needle comprises an inner needle handle and an inner needle core connected with the inner needle, the outer needle handle is provided with an inlet hole, the outer sleeve needle is provided with a middle hole communicated with the inlet hole, and the outer diameter of the outer sleeve needle is smaller than the inner diameter of the inlet hole; the inner needle handle comprises an outer end part and a needle fixing part connected with the outer end part, the needle fixing part is used for installing an inner needle core, the outer diameter of the inner needle core is smaller than the inner diameter of the middle hole of the outer sleeve needle, and the outer end part is abutted with the tail end of the outer needle handle; the magnetic resonance puncture needle also comprises a diamagnetic layer which is arranged on the outer thimble. The magnetic resonance puncture needle can only reduce the size of the artifact of the puncture needle under the magnetic resonance imaging, and can not completely remove the artifact.
When the X-ray development positioning is carried out, after the steel puncture needle enters a human body, the puncture needle is developed into a clear straight line during X-ray scanning, but the puncture needle can be inserted into the human body at any angle along the circumferential direction of the human body, so the angle and the depth of the puncture needle inserted into the human body cannot be determined according to the straight line obtained by the development of the puncture needle and the position of an X-ray machine. In order to obtain a better X-ray developing and positioning effect, bulges are arranged on the needle body or the needle head of the puncture needle, but the structures seriously affect the accuracy of the puncture direction of the puncture needle, so that the deviation of the puncture needle during puncture is possibly greatly increased, the operation difficulty is improved, and the pain of a patient is increased.
Therefore, there is a need for a puncture needle device that can accurately position the puncture angle and puncture depth within the human body.
