[0002] Anesthesiology is a science that studies clinical anesthesia, regulation of vital functions, critical care monitoring and treatment, and pain diagnosis and treatment. It is usually used in surgery or emergency treatment. It is generally believed that anesthesia is a reversible functional inhibition of the central and peripheral nervous systems produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain. In clinical surgery, anesthesia is an indispensable and important part. At present, puncture needles are usually used when anesthetizing patients.

The epidural puncture needle is relatively thick and long, and the puncture needle needs to penetrate thick tissues such as subcutaneous fat. Therefore, it is necessary to maintain stability and apply sufficient external force to push the needle during the operation. Hand shaking will cause the puncture needle to be unstable, resulting in the needle swinging and tilting, which will cause additional harm to the patient. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a puncture auxiliary device for anesthesia, comprising an auxiliary cartridge 1 and an epidural puncture needle 2, a plurality of clamping plates 3 are arranged on the inner side of the auxiliary cartridge 1, the clamping plates 3 and the auxiliary cartridge 1 are connected by elastic members 4, the clamping plates 3 and the auxiliary cartridge 1 are elastically connected, a plurality of guide grooves 5 are arranged on the inner side surface of the auxiliary cartridge 1, and the elastic members 4 and the guide grooves 5 are slidably connected, a flexible ring 6 is arranged at one end of the auxiliary cartridge 1, and the epidural puncture needle 2 is fixed between the plurality of clamping plates 3 and the auxiliary cartridge 1.

[0024] Among them, the auxiliary holder 1, the clamping plate 3 and the elastic member 4 constitute an auxiliary component, which is used in conjunction with the epidural puncture needle 2. When the epidural puncture needle 2 is used for puncture, the puncture needle barrel 10 of the epidural puncture needle 2 is first placed between multiple groups of clamping plates 3, and under the elastic force of the elastic member 4 of the clamping plate 3, the auxiliary holder 1 and the epidural puncture needle 2 are fixed.

[0025] The patient lies on his side, holds his knees with both hands, and places his lower jaw close to his chest in a flexed position. A spinal space is selected between the tenth thoracic vertebra and the fourth lumbar vertebra. Local anesthesia is first performed, and then an epidural puncture needle 2 is used for puncture. Before puncture, Figure 1 As shown, the epidural puncture needle 2 is fixed on the auxiliary holder 1, and then one end of the auxiliary holder 1 is placed on the part to be punctured, the flexible ring 6 is in contact with the skin, the needle 12 is aligned with the part to be punctured, and the preparation work is completed. Then, the puncture needle cylinder 10 is manually pushed, and the multiple groups of clamping plates 3 drive the epidural puncture needle 2 to slide in a straight line along the guide groove 5. The needle 12 at one end of the epidural puncture needle 2 is inserted into the epidural space in a direction perpendicular to the spine to achieve puncture.

[0026] During puncture, the epidural puncture needle 2 is fixed on the auxiliary holder 1, and the moving direction of the epidural puncture needle 2 is linearly guided by the auxiliary holder 1, that is, the puncture direction of the needle 12 is guided to improve the stability during the puncture process. During the puncture process, the hand holds the auxiliary holder 1 for operation, the holding area is large, and the flexible ring 6 at one end of the auxiliary holder 1 is tightly attached to the skin surface for limiting, thereby improving the puncture stability, avoiding the swinging and tilting of the needle 12 caused by hand shaking, and eliminating additional damage caused by improper operation.

[0027] Among them, the elastic member 4 includes a sleeve 7 and a sliding rod 8, one end of the sliding rod 8 is slidably embedded in the interior of the sleeve 7, the other end of the sliding rod 8 is fixedly connected to the clamping plate 3, and a spring 9 is arranged between the sleeve 7 and the sliding rod 8, and the spring 9 is located in the sleeve 7.

[0028] Among them, the epidural puncture needle 2 includes a puncture needle cylinder 10, which is in close contact with the clamping plate 3. When the spring 9 is compressed and elastically deformed, it drives the slide rod 8 to slide relative to the sleeve 7. Multiple groups of clamping plates 3 automatically adjust their positions according to the outer diameter of the puncture needle cylinder 10, and rely on the elastic force of the spring 9 to clamp and fix the epidural puncture needle 2, which facilitates the assembly and disassembly of the epidural puncture needle 2.

[0029] A slider 11 is welded and fixed to the bottom of the elastic member 4 , and the slider 11 is embedded in the guide slot 5 , and the guide slot 5 and the slider 11 are slidably connected.

[0030] Among them, there is a one-to-one correspondence between multiple groups of clamping plates 3, multiple groups of elastic members 4 and multiple groups of guide grooves 5. When the multiple groups of clamping plates 3 are subjected to external driving force, the elastic members 4 fixed thereto slide linearly along the guide groove 5 through the slider 11, thereby driving the epidural puncture needle 2 clamped and fixed by the clamping plate 3 to slide linearly along the guide groove 5 synchronously, guiding the epidural puncture needle 2 and improving its puncture stability.

[0031] Among them, the epidural puncture needle 2 includes a needle 12, and the needle 12 is provided with a scale groove. During puncture, the puncture depth is judged by observing the position of the scale groove of the needle 12 left outside the body. When it is determined that the needle 12 enters the medication gap, the needle core of the epidural puncture needle 2 is pulled out, and the anesthetic drug is injected through the syringe and the epidural puncture needle 2 for anesthesia.

[0032] Two groups of finger support blocks 13 are arranged on the outer side of the auxiliary card holder 1 .

[0033] Among them, the finger support blocks 13 are welded and fixed to the auxiliary holder 1, and the two groups of finger support blocks 13 are symmetrically arranged. When holding the auxiliary holder 1 for limiting, the fingers are pressed on the two groups of finger support blocks 13, which is convenient for applying force. The auxiliary component is easy to hold and operate, and the stability of use is improved.

[0034] Among them, the auxiliary holder 1 is set to a semicircular structure, and the clamping plate 3 is set to an arc structure. When the epidural puncture needle 2 is fixed, the upper part of the epidural puncture needle 2 is exposed to the outside and will not block the line of sight, which is conducive to observing the epidural puncture needle 2 during the puncture process.

[0035] Working principle: when in use, the puncture needle barrel 10 of the epidural puncture needle 2 is placed between multiple groups of clamping plates 3. Under the elastic force of the elastic member 4 of the clamping plate 3, the auxiliary holder 1 and the epidural puncture needle 2 are fixed. The auxiliary holder 1 is held by hand for operation, and one end of the auxiliary holder 1 is placed on the site to be punctured. The flexible ring 6 is in contact with the skin, and the needle 12 is aligned with the site to be punctured. The preparation work is completed, and then the puncture needle barrel 10 is manually pushed. The multiple groups of clamping plates 3 drive the epidural puncture needle 2 to slide in a straight line along the guide groove 5. The needle 12 at one end of the epidural puncture needle 2 is perpendicular to the spine and penetrates into the epidural space to achieve puncture. The puncture depth is judged by observing the position of the scale groove of the needle 12 left outside the body. When it is determined that the needle 12 enters the medication interval, the needle core of the epidural puncture needle 2 is pulled out, and the anesthetic drug is injected through the syringe in combination with the epidural puncture needle 2 for anesthesia.
