Puncture needle for anesthesia in female breast surgery

Abstract

The utility model relates to the technical field of puncture needles for surgical anesthesia, in particular to a puncture needle for female breast surgical anesthesia, which is characterized by comprising a base for connecting an injector; the puncture needle is fixedly connected with the base and used for injecting the anesthetic medicine received by the base into a designated position through the puncture needle; the length of the puncture needle ranges from 14.5 cm to 18.5 cm. Due to the fact that the sizes of breasts of different women are different, if a certain area of the breasts is subjected to puncture anesthesia from hidden parts such as armpits, the penetrating distance needs to be long, and therefore the length of the puncture needle is 14.5 cm to 18.5 cm, and the diameter of the puncture needle is 0.7 mm to 1.2 mm. The bowknot-shaped protrusions are arranged on the two sides of the puncture needle base, so that a doctor can conveniently hold the base with fingers, and then the base is connected with an injector.

Description

TECHNICAL FIELD

[0001] The utility model application relates to the technical field of puncture needle for operation anesthesia, specifically relates to a puncture needle for operation anesthesia of female breast. BACKGROUND

[0002] Because the female has special body structure relative to the male, the individual difference of the breast of the female is huge. Before carrying out the breast operation, need to inject anesthetic drug to the specific area of the breast.

[0003] Because of the lump, tumor or breast cancer of the breast, need to carry out operation to the position of the breast. Before operation, need to carry out local anesthesia. But the existing operation mode can choose to reserve operation incision in the position corresponding to the lump or the position close to it, and the scar after operation is located on the surface of the breast, and is obvious. If want to achieve the effect of beauty, need to leave the incision of operation in the position under the armpit, so that can cover the scar after wearing underwear or swimsuit.

[0004] Similarly, the puncture needle anesthesia before operation also chooses to puncture and inject local anesthetic in the position under the armpit. But the existing puncture needle generally selects the puncture needle for lumbar anesthesia, but the existing puncture needle for lumbar anesthesia is generally about 8-10cm long. Because the thickness of the skin and fat of the human body is about 1-2cm, the individual difference of the breast of the female is huge, and the diameter of the large breast is about 14cm, the depth of the anesthetic puncture needle penetration is 14-16cm, therefore the existing puncture needle for lumbar anesthesia does not meet the puncture needs of the breast operation anesthesia. At the same time, part of the doctors choose to inject several times (supplementary injection) with the puncture needle for lumbar puncture, or directly puncture local anesthesia in the position to be operated in multiple directions, which can easily lead to inaccurate puncture position or small scars caused by puncture, and is not beautiful.

[0005] Therefore, based on the special structure of the breast of the female, the existing anesthetic puncture needle cannot meet the actual needs of the breast operation anesthesia of the female. CONTENT OF THE UTILITY MODEL

[0006] The present application provides a puncture needle for breast operation anesthesia of female, which aims at solving the problem that the current puncture needle for breast operation anesthesia of female cannot puncture from the secret part accurately and then inject anesthetic accurately in the operation area of the breast.

[0007] In order to solve the above technical problem, the present application provides a puncture needle for breast operation anesthesia of female, which comprises:

[0008] The base is used for connecting the syringe;

[0009] The puncture needle is fixedly connected with the base, and is used for injecting the anesthetic received by the base into the specified position through the puncture needle;

[0010] The length of the puncture needle is 14.5-18.5cm;

[0011] The diameter of the puncture needle is 0.7-1.2mm;

[0021] In one embodiment, the bow-shaped protrusions are fixedly connected with the base.

[0022] In another embodiment, the bow-shaped protrusions are detachably connected with the base. After the base is connected with the syringe, the bow-shaped protrusions can be taken off, so as to avoid hurting the skin of other regions of the patient in the process of puncture.

[0023] Further, the base is provided with an opening mark of the top end of the puncture needle, which facilitates the doctor to confirm the direction of drug injection and perform accurate position drug injection.

[0024] It should be noted that, the opening mark of the puncture needle is arranged on the base, which facilitates the doctor to accurately know the opening direction of the puncture needle which has been punctured into the human body, and facilitates accurate positioning and then injection of the drug.

[0025] Further, the outer surface of the puncture needle is provided with a scale.

[0026] Further, the interval distance of the scale is 1cm.

[0027] Further, the interval distance of the scale is 2cm.

[0028] Here, an embodiment is added that the scale is fluorescent, to avoid the problem of light, the doctor can accurately determine the depth of the puncture needle into the body.

[0029] Further, the base away from the end of the puncture needle also includes a stepped protrusion; the stepped protrusion is used to connect the syringe; and the opening mark is arranged on the stepped protrusion.

[0030] Further, the puncture needle top end is provided with an opening; the opening is arranged on the puncture needle top end, which is inclined, and the inclined surface is at an acute angle with the puncture needle.

[0031] Here, it needs to be explained that the end of the puncture needle for connecting the syringe is provided with a stepped protrusion, which is convenient for connecting the puncture needle and the syringe.

[0032] An embodiment is provided here, and the stepped protrusion here has only one step.

[0033] Another embodiment is provided here, and the stepped protrusion here has more than two steps.

[0034] Further, the opening of the puncture needle top end is arranged on one side of the puncture needle top end.

[0035] Here, it needs to be explained that the opening of the puncture needle top end can be arranged on the puncture needle top end similar to the opening of the traditional injection needle, or on the side wall near the puncture needle top end.

[0036] Further, the puncture needle is made of metal; the metal material is stainless steel.

[0037] Here, it needs to be explained that the material of the puncture needle is mainly based on safety and hygiene considerations.

[0038] The beneficial effects of the present application are: the present application provides a puncture needle for female breast surgery anesthesia, characterized in that it comprises a base for connecting a syringe; a puncture needle fixedly connected with the base for injecting anesthetic drugs received by the base into a designated position through the puncture needle; the length of the puncture needle is 14.5-18.5 cm. Because the sizes of different female breasts are different, if the puncture anesthesia is performed on a certain area of the breast from the armpit and other private parts, the distance to be passed through is relatively long, therefore, the length of the puncture needle is 14.5-18.5 cm, and the diameter of the puncture needle is 0.7-1.2 mm. The bow-shaped protrusions arranged on both sides of the puncture needle base are convenient for the doctor to pinch the base with fingers, and then connect the base with the syringe.
