Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a puncture needle with a groove for reflecting ultrasonic waves on one side of a needle sheath.
Background
In the puncture operation under the ultrasonic guidance, the sound wave of the ultrasound cannot be effectively reflected because the surface of the puncture needle is smooth, so that the influence of the needle body is difficult to see from the ultrasonic image, and the specific position and the motion track of the needle body and the needle point in the actual tissue are difficult to judge. In the prior related invention patents, it has been disclosed that the needle sheath of the puncture needle is provided with a circle of reflection grooves, so that the puncture needle with a whole circle can reflect the position thereof well by ultrasonic waves during the operation, but the puncture needle with the structure is easy to break off during the actual use and is difficult to implement. In addition, the existing puncture needle is difficult for an operator to know the needle inserting direction in time to cause deviation of the needle body puncture direction and even injure surrounding tissues by mistake due to lack of judgment of the needle inserting direction of the needle body when the puncture operation is carried out.
Disclosure of Invention
To the defect that exists among the prior art, the utility model aims to provide a puncture needle that one side of pin sheath has reflection ultrasonic wave recess, its structural design of this puncture needle is reasonable, can strengthen the video picture on the supersound image and then conveniently judge concrete position and the movement track of needle body, and the difficult rupture of needle body simultaneously.
In order to achieve the above object, the utility model adopts the following technical scheme:
a puncture needle with a reflection ultrasonic groove on one side of a needle sheath comprises the needle sheath, a needle core matched with the needle sheath and a base arranged at the tail end of the needle sheath, wherein at least one groove for reflecting sound waves is arranged on one side surface of the needle sheath close to a tip end.
Further, a handle is arranged at the tail end of the stylet, wherein an indicating mark for indicating the position of the groove is arranged on the handle.
Further, a handle is arranged at the tail end of the needle sheath, wherein an indicating mark for indicating the position of the groove is arranged on the handle.
Further, the section of the tip of the needle sheath is of a circular or oblique section structure.
Furthermore, the section of the sharp end of the stylet is of a rhombic or oblique section structure.
Compared with the prior art, the scheme has the beneficial technical effects that: according to the puncture needle in the scheme, the groove is formed in one side surface of the needle sheath, so that the position and the moving track of the puncture needle can be clearly displayed under an ultrasonic image on one hand, and meanwhile, the use strength of the puncture needle in the whole use process can be ensured on the other hand; in addition, the handle is arranged in the scheme, and the indicating marks for indicating the directions of the grooves are arranged on the handle, so that an operator can conveniently grasp and control the direction of the puncture needle in time.

Detailed Description
The present invention will be described in further detail with reference to the drawings and the following detailed description.
The utility model aims at solving the problem that the existing puncture needle is easy to break in use, and further provides a puncture needle with a reflection ultrasonic groove on one side of a needle sheath.
Referring to fig. 1 to 2, the puncture needle with a ultrasonic wave reflecting groove on one side of the needle sheath in the embodiment comprises a needle sheath 1, a needle core 2 matched with the needle sheath 1 and a base 4 arranged at the tail end of the needle sheath 1, wherein at least one groove 3 for reflecting sound waves is arranged on one side surface of the needle sheath 1 close to the tip. In practice, the groove 3 may have various curvatures, as long as it can reflect the ultrasound image and show the position of the puncture needle, and for example, a circular arc groove design or a rectangular groove design may be adopted. The number of the grooves 3 can be flexibly adjusted according to the requirement, and the number of the grooves 3 is at least one. It can be understood that on the premise of ensuring the integral use strength of the puncture needle, the position and the action track of the puncture needle can be more clearly displayed as the number of the grooves 3 is larger; when the number of the grooves 3 is multiple, the arrangement of the grooves 3 on the side surface of the needle sheath 1 can be uniformly and equidistantly distributed, or not be regularly distributed; in addition, the depth of the groove 3 can pass through or not pass through the needle sheath body, and the normal reflection of ultrasonic waves and the use strength of the puncture needle can be ensured.
In the practical process, in order to facilitate an operator to conveniently and quickly observe the direction of the puncture needle, namely the direction of the groove 3 on the needle sheath 1 of the puncture needle, the puncture needle is provided with a handle 5 in the embodiment, and the handle 5 can be arranged on the tail end of the needle sheath 1 or the tail end of the needle core 2; the handle 5 can be mounted and connected in a clamping groove and buckle mode, namely, the handle 5 is fixedly connected with the needle sheath 1 (or the needle core 2) in a clamping groove and buckle mode commonly used. The handle 5 is used for indicating the position of the groove 3 by arranging an indicating mark 6 (such as an arrow) on the side edge of the handle 5 opposite to the groove 3, and since the position of the groove 3 on the needle sheath 1 is fixed, the handle 5 is also fixedly arranged on the needle sheath 1 (or the needle core 2), an operator can conveniently and quickly view the position of the groove 3 on the needle sheath 1 in the actual operation process through the indicating mark 6. In addition, the handle 5 may have a square shape, a circular arc shape or other external shapes that are convenient to handle.
In addition, in the embodiment, the tip of the needle sheath 1 on the puncture needle can be designed into a circular or oblique cross-sectional structure; the section of the tip of the stylet 2 can adopt a rhombic or oblique section structure without limitation.
In conclusion, the puncture needle in the scheme is provided with the groove on one side surface of the needle sheath, so that the structure can ensure that the position and the moving track of the puncture needle can be clearly imaged under an ultrasonic image on one hand, and can ensure the use strength of the puncture needle when the puncture needle is integrally used on the other hand; in addition, the handle is arranged in the scheme, and the indicating marks for indicating the directions of the grooves are arranged on the handle, so that an operator can conveniently grasp and control the direction of the puncture needle in time.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalent technologies, the present invention is also intended to include such modifications and variations.
