Embodiment 1

[0041] like Figure 4 As shown, a puncture needle sleeve includes a linear connecting part 1, the radial cross section of the connecting part 1 is circular; the head 2 is integrally formed with one end of the connecting part 1, and is located on the same line On a straight line; the scale line 8 uniformly arranged on the outer periphery of the connecting part 1; the detecting part 4 is arranged on the connecting part 1.

[0042] The head 2 and the connecting portion 1 are on the same straight line, which can facilitate the smooth entry of the puncture cannula. The integral molding of the connecting part 1 and the head 2 is convenient to manufacture. After forming, the surfaces of the connecting part and the head 2 need to be polished to remove surface burrs, which can reduce injuries to patients. The connection part 1 and the head part 2 are made of the same material, titanium steel can be used, and the titanium steel material will not undergo chemical reaction or corrosion u...

Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is that the specific design of the detection part 4 is different, and the rest are the same as Embodiment 1.

[0051] Specifically, such as Image 6 As shown, the detection part 4 adopts a square connection plate 6 , the design of the square connection plate 6 is simple, and the imaging effect is good. The arc surface of the connecting part 1 is provided with a connecting groove matched with the connecting plate 6, and the connecting plate 6 is arranged in the connecting groove. And it is integrally formed with the arc surface of the connecting portion 1 . When making, it can be made by one-piece molding. The connection groove of the present invention is not directly set on the arc surface, but adopts the method of leaving or cutting out a square section of the arc-shaped connecting part. When connecting, connect the connecting plate 6 directly to this section. The square connection plate can increase the refle...

Embodiment 3

[0053] The difference between this embodiment and Embodiment 1 is that the specific design of the detection part 4 is different, and the rest are the same as Embodiment 1.

[0054] Specifically, such as Figure 7 As shown, the design of the detection part 4 of the present invention adopts an arc-shaped protrusion 7 . The number of arc-shaped protrusions 7 is 13, and the arc-shaped protrusions 7 are arranged on the outer periphery of the connecting portion 1 . The height of the arc-shaped protrusion 7 is about 1 mm. The arrangement form of the arc-shaped protrusions 7 is directly arranged on the surface of the connecting part 1, and the distance between two adjacent arc-shaped protrusions 7 is the same, about 10 mm. Two arc-shaped protrusions 7 are arranged between the scale line 8 near the head 2 on the far right and the head 2, and the distance between the nearest arc-shaped protrusion 7 to the head 2 and the head 2 is 2.5 mm. The distance from the second arc-shaped protru...

Abstract

The present invention discloses a puncture needle sleeve. The puncture needle sleeve comprises a connecting part, a head part, scale marks and a detection part; the connecting part is linear and a radial cross section of the connecting part is circular; the head part is integrally formed with one end of the connecting part and positioned on the same straight line with the connecting part; the scale marks are uniformly arranged on a periphery of the connecting part; and the detection part is arranged on the connecting part. The detection part is arranged on the connecting part close to the headpart, intensity of ultrasonic reflection signals is increased due to the arrangement of the detection part, definition of the puncture needle sleeve in a B ultrasonic image is improved, accuracy andsafety of puncture operation are improved, operation difficulty and risks are reduced, and a puncture success rate of a disposable optimal target point is increased.

Description

technical field [0001] The invention relates to the technical field of puncture needles, in particular to a puncture needle sleeve and a puncture needle. Background technique [0002] Interventional ultrasound technology is a minimally invasive operation technology that is guided by ultrasound images in real time and uses puncture needles, guide wires, and catheters to achieve percutaneous puncture to establish surgical operation channels, as well as suction, biopsy, drainage, and drug injection. In the specific implementation of interventional ultrasound technology, there will be differences in puncture instruments due to different parts and purposes, but the core instruments are puncture needles, because they are the most important and basic instruments to achieve "intervention" operations. The puncture needle is usually composed of a cannula and a needle core. According to different uses, it can have various types such as shape structure, length, thickness, needle core an...
