Double-sided needle groove, frame body and puncture frame

Abstract

A double-sided needle groove, a frame body and a puncture frame, wherein the double-sided needle groove has an axisymmetric outer contour, and is provided at one side with at least one needle slot a (1) and at the other side with at least one needle slot b (2); and the needle slot b (2) is fan-shaped. The double-sided needle groove is provided with one or more needle slots a (1) having a fixed needle insertion angle and a needle slot b (2) having an adjustable needle insertion angle, and the needle slot a (1) and the needle slot b (2) respectively correspond to the diameters of puncture needles and may be designed to meet multiple width specifications. During the performance of a B-ultrasound puncture operation, based on operation requirements of a surgeon for a fixed or adjustable angle, there is only a need to switch front and back sides of the double-sided needle groove, thus avoiding the need for an additional puncture frame, and switch the needle slots according to the diameters of the puncture needles. As can be seen, the double-sided needle groove can be applied to various types of B-ultrasound puncture operations and can effectively reduce the number of accessories in the puncture operations, thereby providing fast installation, saving resources and reducing costs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) Hereinafter, the structures of the present invention will be explained in detail with reference to the figures.

(9) As shown in FIGS. 1-3, the present invention provides a double-sided needle groove, wherein the double-sided needle groove, which has a “fan-like” outer contour, is provided at one side with three needle slots a1, and the three needle slots a1 may be designed to meet multiple specifications so that apertures thereof are in one-to-one correspondence to the diameters of puncture needles; and the double-sided needle groove is provided at the other side with one fan-shaped (a certain angle range may be provided) needle slot b2, and the needle slot b2 may be designed to meet multiple width specifications so that dimensions thereof are in one-to-one correspondence to the diameters of the puncture needles.

(10) The double-sided needle groove of the present invention is provides a rotating convex half shaft a3 and a rotating convex half shaft b4, on each side respectively, which are symmetric about a centerline of the outer contour of the double-sided needle groove. The rotating convex half shaft a3 and the rotating convex half shaft b4 are respectively provided with a notch a31 and a notch b41, which are symmetric about the centerline of the outer contour of the double-sided needle groove.

(11) It is understood by those skilled in the art, that the number of the needle slot a1 of the double-sided needle groove provided by the present invention may be one, two, three, four or more. The specific number can be set according to the actual production and application requirements.

(12) As shown in FIG. 4, the present invention provides a frame body for installing the above double-sided needle groove, wherein the frame body is provided with a needle insertion plate 5 in cooperation with the double-sided needle groove. The needle insertion plate 5 is provided at one side with a rotating concave half shaft 51 in cooperation with the rotating convex half shaft a3 or rotating convex half shaft b4, and at the other side with a hook 52 in cooperation with the rotating convex half shaft a3 or rotating convex half shaft b4. The hook 52 is provided with a boss 521 in cooperation with the notch a31 or notch b41. The boss 521 is provided with a pit 5211.

(13) The needle insertion plate 5 is provided at the bottom with an elastic piece 53, and a bump 531 is disposed at a position on the elastic piece 53 in correspondence to the rotating convex half shaft a3 or rotating convex half shaft b4.

(14) The rotating concave half shaft 51 and the hook 52 are used for fixing the double-sided needle groove. The pit 5211 on the boss 521 allows the user to manually remove the double-sided needle groove from the frame body. The bump 531 on the elastic piece 53 is used to eject the double-sided needle groove when it is removed.

(15) As shown in FIGS. 5-6, the present invention provides a puncture frame comprising a double-sided needle groove according to any one of the above and a frame body according to any one of the above. The specific use methods are as follows:

(16) I. A use method of the fixed needle insertion angle side of the double-sided needle groove: first installing the frame body on an ultrasonic probe, selecting a double-sided needle groove of a required aperture, aligning the rotating convex half shaft b4 on the double-sided needle groove into the rotating concave half shaft 51 on the frame body, then aligning the notch a31 on the double-sided needle groove with the boss 521 on the frame body, and pressing the double-sided needle groove hard to deform the hook 52 outwardly to fit. Then buckle in and install the double-sided needle groove and the needle insertion plane 54 of the needle insertion plate 5 in place, so that the resultant structure, after the installation, is as shown in FIG. 5. At this time, the needle slot a1 with a fixed needle insertion angle is fitted to the needle insertion plane 54 so as to accomplish the purpose of needle insertion at a fixed angle.

(17) II. A use method of the adjustable needle insertion angle side of the double-Sided needle groove: first installing the frame body on an ultrasonic probe, selecting a double-sided needle groove of a required aperture, aligning the rotating convex half shaft a3 on the double-sided needle groove into the rotating concave half shaft on the frame body, then aligning the notch b41 on the double-sided needle groove with the boss 521 on the frame body, and pressing the double-sided needle groove hard to deform the hook 52 outwardly to fit. Then buckled in and install the double-sided needle groove and the needle insertion plane 54 of the needle insertion plate 5 in place, so that the resultant structure, after the installation, is as shown in FIG. 6. At this time, the needle slot b2 with an adjustable needle insertion angle is fitted to the needle insertion plane 54 so as to accomplish the purpose of needle insertion at an adjustable angle.

(18) After the puncture operation is completed, the pit 5211 on the hook 52 is held by hand(s), so as to apply a force outwardly, thus deformed the hook 52. This in turn causes the bump 531 on the needle insertion plate 5 to eject and takes off the double-sided needle groove.

(19) The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, simple improvements and the like made in the essential contents of the present invention shall be included in the scope of protection of the present invention.
