Description

Brachial plexus blocking needle sleeve under ultrasonic guidance and using method thereof
Technical Field
The invention relates to an brachial plexus blocking needle sleeve under ultrasonic guidance and a using method thereof.
Background
Currently used neurostimulation blocking needles are mainly divided into two types:
firstly, an outer target needle, namely a bevel needle (the needle point is an acute angle less than 20 degrees), has the defects of being easy to cause cutting injury of nerve vessels, and easily causing more unnecessary injuries when the outer target needle walks in tissues, such as cutting of the tissues, puncturing of blood vessels (hematoma is easy to appear in arteries and extravasated blood is easy to appear in veins), and puncturing or cutting of nerves can cause numbness of skin in a corresponding innervation area of the nerves and weakness of corresponding innervation muscles when the nerves are heavy;
and secondly, the inner core needle, namely the side hole needle (the needle point is a round-thorn needle point), has the defects of troublesome skin puncture process, large puncture force and large pain of a patient, and meanwhile, in the puncture process, a needle tube with smaller outer diameter is selected as much as possible in order to avoid possible damage to nerves and blood vessels. Because the needle body is thin, when the deep puncture is carried out, the needle body is easy to deform along with the movement of human tissues such as muscles, the needle point is displaced, and the distance between the needle point and nerves deviates.
When the indwelling catheter is placed through the sheath needle, the position of the indwelling catheter is inaccurate, and the continuous blocking effect cannot be ensured.
Disclosure of Invention
The invention provides an brachial plexus blocking needle sleeve under ultrasonic guidance and a using method thereof, aiming at solving the technical problems, and the invention greatly relieves the puncture pain of a patient, has accurate tube placement and can realize the continuous blocking effect.
In order to achieve the purpose, the invention adopts the following technical scheme:
an brachial plexus nerve block needle kit under ultrasonic guidance comprises an outer sheath needle, an outer sheath needle core, an inner core needle, a indwelling tube and an indwelling tube connector, wherein the outer sheath needle core is matched with the outer sheath needle, when the outer sheath needle core is inserted and clamped in the outer sheath needle, the head of the outer sheath needle core is flush with a needle head of the outer sheath needle, the indwelling tube is sleeved on a needle body of the inner core needle, a side hole to a needle point of the inner core needle is exposed out of the indwelling tube, when the inner core needle sleeved with the indwelling tube is inserted and clamped in the outer sheath needle, the tail end of the indwelling tube extends out of the needle head of the outer sheath needle, and the indwelling tube connector is matched with the indwelling tube.
The outer sheath needle is an inclined surface thick needle, the outer sheath needle comprises a thick needle body, the tail end of the thick needle body is fixedly inserted into the handle part, the handle part is provided with a pore passage communicated with the through hole of the thick needle body, the handle part of the outer sheath needle is additionally provided with a pressing part used for pressing the tail end of the indwelling tube or an opening which corresponds to the tail part of the indwelling tube.
The pressing part is a transparent elastic body arranged on the handle part of the sheath needle.
The inner core needle is a side hole fine needle, the inner core needle comprises a fine needle body, the fine needle body is fixedly inserted into the handle part, and the handle part is provided with a pore canal communicated with the pore cavity of the fine needle body.
The handle part of the sheath needle and the handle part of the inner core needle are in a splicing structure.

The indwelling tube is also matched with a fixator.
A method for using an ultrasonic-guided brachial plexus nerve block needle kit comprises the steps of firstly inserting a needle core of an outer sheath needle into the outer sheath needle, puncturing skin and subcutaneous tissues together, staying outside an brachial plexus nerve sheath, pulling out the needle core of the outer sheath needle, placing the inner core needle sleeved with a indwelling tube into the outer sheath needle, enabling a handle part of the inner core needle to be matched with a handle part of the outer sheath needle in a clamping manner, enabling the inner core needle to be fixed with the outer sheath needle, enabling a needle point of the inner core needle to extend out of a needle head hole of the outer sheath needle, holding the handle part of the inner core needle to adjust a puncturing angle, avoiding axillary artery and axillary vein, puncturing the brachial plexus nerve sheath, opening a nerve stimulation instrument after a target nerve is reached, confirming that muscle movement governed by the corresponding brachial plexus nerve is performed, finishing local anesthetic injection, holding a handle of the outer sheath needle if multiple nerve blocks are required, withdrawing the needle point of the inner core needle out of the brachial plexus nerve sheath, then adjusting the angle, carrying out next nerve positioning, after the nerve positioning is completed, pressing the pressing part or the opening of the sheath needle by hands, pressing the indwelling tube, pulling out the inner core needle, then using the head of the needle core of the sheath needle to prop against the tail end pipe orifice of the indwelling tube, pushing the indwelling tube downwards and simultaneously pulling out the sheath needle, staying the indwelling tube on the body, then connecting the indwelling tube connector at the tail end of the indwelling tube, carrying out next administration operation, and finishing the puncture. .
The invention has the beneficial effects that: firstly, the outer target needle and the needle core of the outer target needle are combined for puncture, the needle point is kept at a position 2 cm away from the nerve through ultrasonic observation, the puncture force is small due to the inclined needle point, the pain of a patient is small, a puncture channel can be quickly established, and the nerve and the blood vessel can be prevented from being damaged due to the long distance from the nerve. The needle core of the outer target needle is pulled out, and then the inner core needle penetrates through the needle tube of the outer target needle, and the front section of the inner core needle is provided with an ultrasonic development design, so that the inner core needle can be obviously distinguished from the needle body of the outer needle under the ultrasonic condition, and then the inner core needle goes deep to perform the nerve stimulation blocking operation. Under the coordination of ultrasound, the inner core needle is guided to approach the nerve and the needle point is moved to the target area, and the needle point of the side hole of the inner core needle is designed to effectively prevent the nerve and the blood vessel from being cut and damaged; the remaining tube is arranged in the inner core needle sleeve, and can be directly and accurately left near the target nerve after puncture administration, so that the subsequent continuous blocking effect is ensured; compared with the traditional indwelling tube, the indwelling tube is much shorter than the traditional indwelling tube exposed outside the skin, so that the problem of replacing the indwelling tube again cannot occur, a fixer is arranged on the external wall of the indwelling tube outside the skin and the indwelling tube connector till now, and medical adhesive plaster is used for fixing the fixer on the skin to prevent the indwelling tube from displacing.
