Description

Technical Field

[0001] This utility model relates to a blocking needle, specifically an improved blocking needle. Background Technology

[0002] Nerve block needles are a well-known medical device. For detailed structure, please refer to the Chinese authorized patent, publication number CN209032563U, which discloses a nerve block needle.

[0003] Based on the technology of the aforementioned patents, since the blocking needle consists of two parts, a needle sheath and a needle core, and the two are designed to be inserted together, during the puncture process, the puncture of the needle core and the puncture of the end of the needle sheath act on the human tissue at the same time, which causes great pain to the body. It is hoped that a good solution can be found to reduce the pain caused by this puncture. Utility Model Content

[0004] The purpose of this invention is to provide an improved blocking needle to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved blocking needle includes:

[0007] The needle sleeve has a connector fixedly installed at its first end, while the inner wall of the second end is beveled and its end is a loop.

[0008] The needle core has a handle fixedly installed at its first end and a needle head fixedly installed at its second end, with an irregularly shaped curved portion provided between the needle head and the needle core;

[0009] The irregular curved portion is composed of two arc segments, and the inner arc apex of the two arc segments face opposite directions. The connection between the inner arc surface of the first arc segment and the end of the second arc segment abuts against the loop.

[0010] The diameter of the circumference formed by the outer arc apex of the second arc segment is larger than the diameter of the circumference of the loop.

[0011] Preferably, both the needle core and the needle tip are hollow structures.

[0012] Preferably, the connector has an elliptical structure and symmetrical recesses are provided at one end facing the needle sleeve.

[0013] Preferably, the end of the connector is fixedly mounted with a spherical airbag that wraps around the needle sleeve portion.

[0014] Preferably, the handle has a semi-circular structure, and a rubber block that is fixedly disposed on its horizontal surface to be inserted into the connector port.

[0015] Preferably, a textured silicone outer cover is fixedly provided on the outer side of the handle.

[0016] Preferably, the needle sleeve has multiple graduated rings arranged in a linear array.

[0017] In the above technical solution, the improved blocking needle provided by this utility model has the following beneficial effects: the aforementioned irregularly shaped curved portion and the irregularly shaped curved portion designed at the needle tip connection part, and the irregularly shaped curved portion is composed of two arc-shaped segments, and the connection between the inner arc surface of the first arc segment and the end of the second arc segment abuts against the loop. The diameter of the circumference formed by the outer arc apex of the second arc segment is larger than the diameter of the circumference of the loop. Therefore, during the puncture process, the needle tip bears the responsibility of puncture, while the second end of the needle sheath is blocked by the irregularly shaped curved portion, avoiding further cutting during puncture, thereby reducing the pain caused by puncture.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, an improved blocking needle includes:

[0026] The needle sleeve 1 has a connector 2 fixedly installed at its first end, while the inner wall of the second end is a bevel 11 and its end is a loop 12.

[0027] The needle core 3 has a handle 4 fixedly installed at its first end and a needle tip 31 fixedly installed at its second end. An irregularly shaped curved part 32 is provided between the needle tip 31 and the needle core 3.

[0028] The irregularly shaped curved part 32 is composed of two arc segments, and the inner arc apex of the two arc segments faces opposite directions, and the connection between the inner arc surface of the first arc segment and the end of the second arc segment abuts against the loop 12.

[0029] The diameter of the circle formed by the outer arc apex of the second arc segment is greater than the diameter of the circle of loop 12.

[0030] Specifically, in the embodiment, both the needle sleeve 1 and the needle core 3 are produced by mold casting, and then the burrs formed by casting are removed by sandblasting machine, and then the connector 2 and the handle 4 are formed by injection molding process.

[0031] In the above-described technology, the irregularly shaped curved portion 32 is designed at the connection point of the needle tip 31. This irregularly shaped curved portion 32 consists of two arc-shaped segments, and the connection between the inner arc surface of the first arc-shaped segment and the end of the second arc-shaped segment abuts against the loop 12. The diameter of the circumference formed by the outer arc apex of the second arc-shaped segment is larger than the diameter of the circumference of the loop 12. Therefore, during the puncture process, the needle tip 31 bears the responsibility of puncture, while the second end of the needle sheath 1 is blocked by the irregularly shaped curved portion 32, avoiding further cutting during puncture and thus reducing the pain caused by puncture.

[0032] It should be noted that both the needle core 3 and the needle tip 31 mentioned above are hollow structures.

[0033] As a further embodiment of this utility model, combined with Figure 1 and Figure 3 As shown, connector 2 has an elliptical structure and recesses 21 are symmetrically provided at one end facing the pin sleeve 1.

[0034] Specifically, when performing puncture with the needle, the fingers can be positioned within the recessed portion 21, while the palm rests against the handle 4. The handle 4 has a semi-circular structure, and a rubber block 41 that is fixedly installed on its horizontal surface to engage with the connector 2 port provides a good tactile feel.

[0035] As a further embodiment of this utility model, combined with Figure 1 and Figure 3 As shown, the end of connector 2 is fixedly mounted with a spherical airbag 5 that wraps around the needle sleeve 1.

[0036] Specifically, the added spherical airbag 5 can provide soft support for the two fingers when holding the puncture hand, increasing the doctor's comfort when holding the puncture hand.

[0037] As a further embodiment of this utility model, combined with Figure 1 and Figure 3 As shown, a textured silicone outer cover is fixedly provided on the outer side of the handle 4.

[0038] Specifically, it increases friction to make it easier for the fingers to pull off the handle 4.

[0039] As a further embodiment of this utility model, combined with Figure 1 and Figure 3 As shown, the needle sleeve 1 has multiple graduated rings arranged in a linear array.

[0040] Specifically, this makes it easier for doctors to observe the puncture depth.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
