Embodiment 1

[0035] Such as Figure 8 As shown, the puncture rack device described in this specific embodiment includes: a clamping mechanism 1, a puncture needle rack 2, and an angle adjustment mechanism 3.

[0036] The clamping mechanism 1 is used to clamp the probe 4 on the one hand, and is used to connect the puncture needle holder 2 and the angle adjustment mechanism 3 on the other hand, and is fixed on the probe 4 and the probe 4 through the clamping mechanism 1. Use together.

[0037] On the one hand, the angle adjustment mechanism 3 is fixedly connected with the clamping mechanism 1, and fixed on the probe 4 through the clamping mechanism 1, and on the other hand, it is hinged with the puncture needle frame 2 through a pin (not shown in the figure). , so that the puncture needle frame 2 can rotate around the pin shaft, and the rotation angle of the puncture needle frame is limited and positioned by the angle adjustment mechanism.

[0038] In this specific embodiment, in order to ...

Embodiment 2

[0059] A puncture rack device is disclosed, the puncture rack device includes the puncture needle rack as described in the first specific embodiment, and the puncture needle rack is as described in the first specific embodiment, and will not be repeated here.

Abstract

The invention discloses a puncture needle holder which comprises a needle bed and a base. A plurality of puncture needle guiding grooves with different diameters are distributed in the surface of the needle bed in the axial direction. The inner portion of the base is hollow, a pressing cover structure capable of being opened and closed relative to a base body is arranged on the upper surface of the base, the needle bed is rotatably arranged in the base in the axial direction of the base, and when the puncture needle guiding grooves rotate to the position located under the pressing cover, the closed pressing cover can match with the guiding grooves to define the guiding space of a puncture needle. Two opposite containing grooves capable of containing puncture needles are formed in the two ends respectively, located on the matching position of the pressing cover and the guiding grooves, of the base in the axial direction. The invention further discloses a corresponding puncture frame device. Puncture needles of different specifications can be replaced on an identical puncture needle holder conveniently by using the puncture needle holder.

Description

technical field [0001] The invention relates to the technical field of puncture, in particular to a puncture needle frame and a puncture frame device thereof. Background technique [0002] When medical personnel need to take out samples from patients or inject medicines into patients, they need to use puncture needles for puncture operation. The puncture needle holders used now generally include needle holders with holes, and when puncture needles of different specifications are used for puncture, it is necessary to replace the needle holders of different specifications. Some puncture racks have catheters in the needle seat holes, and catheters of different specifications need to be replaced when using puncture needles of different specifications. [0003] The above-mentioned existing solutions need to replace needle bases and catheters of different specifications to be used with puncture needles of different specifications. The product has many accessories, which is easy t...
