Description

Technical Field

[0001] The utility model discloses a novel nerve blocking needle, belonging to the field of nerve blocking needles. Background Art

[0002] Nerve block is an injection that blocks the conduction of nerve function and is a type of closed injection. This medical technology is mainly used to block the vicious cycle of pain, improve blood circulation, etc., and is commonly used in clinical practice.

[0003] Nerve block needles are usually injected with anesthetic drugs around nerve trunks, plexuses, ganglia, etc. to block the connection between the pain nerves in the brain and produce anesthesia in the innervated area, thereby paralyzing the nerves. Nerve block needles can not only block sensory nerves, but also relieve muscle spasms caused by pain and improve local vicious cycles. For some patients with local diffuse congestion and edema, nerve block needles can be injected to eliminate edema and promote the absorption of inflammation. In order to facilitate insertion, existing nerve block needles are equipped with an auxiliary positioning and pushing structure at the needle tip. However, due to the wearing of gloves and the different finger sizes of different doctors, an auxiliary positioning and pushing structure that is too large or too small will affect the operating feel. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a new type of nerve block needle to solve the problem that in order to facilitate insertion, the existing nerve block needles are provided with an auxiliary positioning and pushing structure at the needle tip, but due to the wearing of gloves and the different sizes of fingers of different doctors, the auxiliary positioning and pushing structure is too large or too small, which will affect the operating feel.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a new type of nerve block needle, whose structure includes an injection tube connector, an assembly tube is provided at the upper end of the injection tube connector, and the upper end of the assembly tube is connected to the nerve block needle tube, a pushing block is provided at the middle section of the assembly tube, and an extended pushing plate is provided at both ends of the left and right ends of the pushing block, and an adjustment groove is provided at one end of the extended pushing plate facing the pushing block, and an adjustment plate that slides into the adjustment groove is provided on the pushing block, and an elastic clamping block is provided on the top surface of the inner wall of the adjustment groove, and a plurality of clamping grooves are provided on the top surface of the adjustment plate in sequence from left to right, and the elastic clamping block is engaged with one of the clamping grooves, and a limit block is provided on the bottom surface of the end of the adjustment plate, and a limit slide rail slidably connected to the limit block is provided on the bottom surface of the inner wall of the adjustment groove.

[0006] Furthermore, a liquid injection hole which is communicated with the liquid injection tube connector and the nerve block needle tube respectively is provided at the center of the pushing block.

[0007] Furthermore, a liquid injection pipe connecting port is provided at the lower end of the liquid injection pipe connecting piece.

[0008] Furthermore, the pushing block and the adjusting plate are an integrated structure.

[0009] Furthermore, the adjustment plate is made of hard plastic material.

[0010] The beneficial effects of the utility model are as follows: the nerve blocking needle adopts an extended adjustable auxiliary pushing structure, which can be adjusted to a suitable pushing size according to the doctor's operating habits. When in use, it is only necessary to pull the extended pushing plate with a little force to make the extended pushing plate move away from the pushing block, and the adjusting plate will slide out of the adjusting groove. During the adjustment process, the elastic card block will elastically fit into the corresponding card groove to play a positioning role. After the adjustment is completed, the extended pushing plate cooperates with the adjusting plate and the pushing block to form a suitable pushing range, which is convenient to operate.
