Description
Technical Field
The invention relates to the technical field of puncture needles for medical clinic use, in particular to a puncture needle guided by ultrasonic images.
Background
In the medical field, for example, when a nerve is to be accurately found, the puncture needle needs to be used, so that the puncture needle needs to be correctly positioned, an ultrasonic device is used, the puncture is carried out while ultrasonic echo from the puncture needle is confirmed under the guidance of an ultrasonic image, dangerous structures (such as pleura, blood vessels and the like) are avoided, whether the puncture needle reaches the optimal position of the target nerve is correctly positioned in real time, and therefore, the injected anesthetic or analgesic agent can perfectly wrap and infiltrate the target nerve to achieve the effect of blocking nerve conduction.
Ultrasonic imaging is an image in which an ultrasonic wave of an ultrasonic probe as an ultrasonic wave transmitting/receiving element is irradiated to a puncture needle through a medium, an ultrasonic echo, which is a reflected wave from the puncture needle, is received by the ultrasonic probe, and an image of the puncture needle is subjected to data processing by an ultrasonic device and displayed on an ultrasonic screen.
As a conventional puncture needle used for ultrasound guidance, for example, a puncture needle provided on an outer surface of a distal end of a needle body is known, and in the conventional puncture needle, an ultrasound is reflected by processing the distal end of the needle body, but as an angle formed by an irradiation path of the ultrasound and a needle body of the puncture needle becomes smaller and smaller, particularly, 40 ° or less, an intensity of an ultrasound echo captured by an ultrasound probe decreases, an ultrasound image of the puncture needle on an ultrasound device becomes unclear and unstable, and it is difficult to locate a position of the puncture needle.
As the traditional puncture needle with the front end processed to reflect ultrasonic waves, the processed length is short, is generally between 3mm and 20mm, and is concentrated at the front end of the needle body, however, the length of the puncture needle for clinical application is generally between 50mm and 150mm, and in the process of puncture, the ultrasonic image of the unprocessed needle body part is unclear, so that the puncture path of the needle body is not easy to distinguish.
The puncture needle partially reflects ultrasonic waves after being processed has lower distribution density of grooves for processing and reflecting the ultrasonic waves, and has higher requirements on the angle of a needle body of the puncture needle for irradiating the ultrasonic waves in the puncture process.
Disclosure of Invention
The invention aims to solve the defects that in the prior art, the distribution density of grooves for processing reflected ultrasonic waves is low and the requirement on the angle of a puncture needle body for irradiating ultrasonic waves during puncture is high due to the fact that part of puncture needles for processing reflected ultrasonic waves are processed, and provides an ultrasonic image guided puncture needle.
In order to achieve the purpose, the invention adopts the following technical scheme:
a puncture needle guided by ultrasonic images comprises a puncture needle body, wherein a plurality of reflection grooves are formed in the puncture needle body, a right-angle three-side reflector is contained in each reflection groove, and the puncture needle body comprises an edge and an edge formed by obliquely cutting the front end of the puncture needle body.
Preferably, the puncture needle body is a needle tube body formed of a thin metal tube made of stainless steel or the like.
Preferably, the reflective notch is a pentahedral notch disposed near the front and on the surface of the needle body.
Preferably, the number of the right-angle three-sided mirrors is three, and the right-angle three-sided mirrors include: the light source comprises an aE-EF-EH right-angle three-sided reflector, a bF-FE-FG right-angle three-sided reflector and a dH-HE-HG right-angle three-sided reflector; four rows are formed at a predetermined interval in the circumferential direction of the puncture needle body, and reflection grooves are provided on the surface of the puncture needle body; the right-angle three-side reflecting mirror is composed of three mirror surfaces which are perpendicular to each other, after the ultrasonic probe irradiates, incident waves are reflected by the three mirror surfaces to become reflected waves which are parallel to the incident waves, namely the incident waves are parallel to the return waves, and the ultrasonic echo is grabbed by the ultrasonic probe, so that ultrasonic imaging is realized.
Preferably, the reflection groove covers the puncture needle body as far as possible, the puncture path can be observed through ultrasonic needle body imaging, and the front end of the needle body is arranged at a position close to the frontal surface, so that the position of the front end (needle point) of the puncture needle is accurately positioned.
Compared with the prior art, the invention has the advantages that:
the invention provides a puncture needle which can ensure clear and stable ultrasonic imaging even if the angle between the ultrasonic wave irradiation direction emitted by an ultrasonic probe and the puncture needle body as an axis is smaller;
the invention relates to a puncture needle capable of accurately positioning the position and the puncture path of the puncture needle. It has the characteristics that: the needle tube comprises a needle tube body with a sharp tip formed at the front end and at least one right-angle three-mirror arranged at a specified position of the needle tube body. Here, the needle tube body is an inner needle and an outer needle of a double needle, a single tube structure, or other needles, and a rectangular three-sided mirror is provided on the outer surface thereof regardless of the inner needle, the outer needle, or the single tube structure.
The puncture needle of the invention can clearly and stably carry out ultrasonic imaging on the needle tube body including the front end of the needle body even if the angle between the ultrasonic irradiation direction emitted by the ultrasonic probe and the needle body of the puncture needle is smaller or smaller.
The length of the processed reflected ultrasonic wave of the puncture needle body is longer, and the path of the needle body of the puncture needle is convenient to observe.
The density of the ultrasonic waves reflected by the puncture needle body needle in the processing process is higher, the ultrasonic image of the puncture needle is clearer and more stable, and the requirement on the needle body angle of the puncture needle irradiated by the ultrasonic waves is not met.
Through set up the recess that reflects ultrasonic wave on the pjncture needle, contain three right angle trihedral mirror, incident wave and the back wave in the ultrasound irradiation pjncture needle are for being parallel, so the ultrasonic wave of shining by ultrasonic probe returns ultrasonic probe through the reflection of puncture needle, consequently even ultrasonic wave shines the angle that route and pjncture needle body formed for the axle diminishes, the ultrasonic wave also can be reflected through intensive right angle trihedral mirror, returns ultrasonic probe to include the clear ultrasonic imaging of needle body front end with the pjncture needle.
Because the right-angle three-side reflecting mirror is arranged at the front end (needle point) of the needle body and the needle body, the front end (needle point) of the needle body and the needle body can be clearly developed, and the position of the needle point and the path of the needle body can be accurately positioned.
Three right-angle three-surface reflectors are arranged in each groove, and a plurality of rows of grooves are distributed within 360 degrees of the needle body, so that the orientation of the puncture needle can not be changed, incident waves and reflected waves in the puncture needle are irradiated by ultrasonic waves and are parallel, therefore, the direction of the puncture needle is irrelevant, and the ultrasonic imaging can still be clear.
