Abstract

A kind of ultrasound guidance palm wrist finger-joint chamber injection puncture special needle, cooperation syringe is for slapping the puncture of wrist finger-joint chamber, it include: the needle body with distal end needle body (1) and proximal end needle body (2), the distal end needle body (1) and the proximal end needle body (2) are configured to intersect at a certain angle；And the needle stand (3) of the connection needle body and syringe.Ultrasonic guidance palm wrist finger-joint injection puncturing needle special provided by the utility model can preferably meet the clinical demand that palm wrist finger-joint chamber injection punctures, the dog-ear of its needle body advantageously implements ultrasonic guidance palm wrist finger-joint chamber injection convenient for clinical manipulation person, the incidence of the complication such as articular cartilage damage, local hematoma is reduced simultaneously, reduces puncture wound.

Description

Ultrasound guidance slaps the injection of wrist finger-joint chamber and punctures special needle

Technical field:

The utility model relates to a kind of palm wrist finger-joint chamber injections of ultrasound guidance to puncture special needle, be especially suitable for palm wrist Finger Minor articulus puncture injection.Belong to the field of medical instrument technology.

Background technique:

Existing ultrasound guidance arthrocentesiS pumping needle mostly uses clinically used disposable sterile injector, super Sound guidance is lower to guide positioning inserting needle by ultrasonogram, carries out injection of drug.But since palm wrist finger-joint cavity volume is small, Structure is complicated, the narrow injustice in joint space, and puncture needle disposably accurately enters articular cavity, and avoids periarticular cartilage and have Certain difficulty be easy to cause a series of complication based on cartilage damage, very relies on the experience of operator.

Summary of the invention:

In order to overcome limitation of the existing common disposable sterile injector on joint injection, the utility model is provided A kind of puncture injection needle more adapts to the joint structure of palm wrist finger Minor articulus complexity, the puncture injection for safety and precise of being more convenient for.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

(1) a kind of ultrasound guidance palm wrist finger-joint chamber injection punctures special needle, and cooperation syringe is for slapping wrist finger Joint puncture, wherein it includes: with distal end needle body and proximal end that ultrasound guidance, which slaps the injection of wrist finger-joint chamber and punctures special needle, The needle body of needle body, the distal end needle body and the proximal end needle body are configured to intersect at a certain angle；And the connection needle body With the needle stand of syringe.

(2) injection of the palm of ultrasound guidance described in above scheme (1) wrist finger-joint chamber puncture special needle be divided into it is adult and Two kinds of models of children, wherein adult model needle body overall length 3.0cm, the wherein long 2.0cm of proximal end needle body, distal needle body length 1.0cm； Children's model needle body overall length 2.0cm, the long 1.3cm of proximal end needle body, distal needle body length 0.7cm.

(3) injection of ultrasound guidance palm wrist joint chamber described in above scheme (1) or (2) punctures in special needle, described remote Holding needle body and the proximal end needle body is an interconnected entirety, and the distal end needle body and the proximal end needle body at 135 °~ 150 ° of angles, preferably 135 °.

(4) palm of ultrasound guidance described in above scheme (1) or (2) wrist finger-joint chamber injection punctures in special needle, institute State the model 23G of needle body.

The utility model has the beneficial effects that its dog-ear is more in line with joint space curvature, accidental injury articular cartilage can be reduced Probability；Its thinner needle body can avoid wearing out the shallow blood vessel of table to a certain extent causes hemotoncus, while can reduce puncture wound.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model

In figure: 1, distal end needle body, 2, proximal end needle body, 3, needle stand, 4, syringe

Specific embodiment:

With reference to the accompanying drawing 1, the utility model is further described.

As shown in the picture, body puncture needle is a kind of suitable for the dedicated of ultrasound guidance palm wrist finger-joint chamber puncture injection Needle, including needle body and needle stand 3 with distal end needle body 1 and proximal end needle body 2, the proximal end needle body 2 of needle body is removably attachable to Needle stand 3 can according to need the needle body of different model being connected to syringe 4 by needle stand 3.

Proximal end needle body 2 and distal end needle body 1 are integrated, and are interconnected, and be 23G (outer diameter 0.6mm).

Needle body is divided into adult and two kinds of models of children, and adult model overall length 3.0cm, wherein proximal end needle body 2 is 2.0cm long, far Hold needle body 1 1.0cm long；Children model overall length 2.0cm, wherein proximal end needle body 2 is 1.3cm long, and distal end needle body 1 is 0.7cm long.

1 axis of distal end needle body and 2 axis of proximal end needle body are at 135 °~150 ° angles, and preferably 135 °.

Puncture needle body, which is connected by needle stand 3 with ordinary syringe 4, to be used cooperatively, to intraarticular injection liquid.Utilize this The structure of sample can preferably meet the clinical demand that palm wrist finger-joint chamber injection punctures, and the dog-ear of needle body is convenient for clinical behaviour Author advantageously implements ultrasonic guidance palm wrist finger-joint chamber injection, while it is concurrent to reduce articular cartilage damage, local hematoma etc. The incidence of disease reduces puncture wound.
