Embodiment 1

[0030] A dedicated puncture set for nerve blocks, such as figure 1 , 2 , as shown in 4-10, includes a power cavity, and a power structure 3 is provided on the power cavity; a fixed structure 1 is also connected to the power cavity, and a syringe 7 is detachably connected to the fixed structure 1, and a driving structure 3 is connected to a drive The syringe 7 pushes the drug and withdraws the drug pushing structure 4; the syringe 7 is detachably connected with the infusion tube 6, the infusion tube 6 is connected with the puncture needle 5, and the puncture needle 5 is provided with a handle; the power structure 3 It includes a driving assembly, and the driving assembly is connected with a speed regulating assembly that can adjust the pushing and withdrawing speed of the drug pushing structure 4; through the setting of the driving assembly and the speed regulating assembly, the pushing and withdrawing speed of the drug pushing structure 4 can be uniform. Adjustable, so that t...

Embodiment 2

[0049] A dedicated puncture set for nerve blocks, such as image 3 As shown, the structure is the same as that of Embodiment 1, the difference is that: the drive assembly is a motor fixed to the power chamber, and the handle on the puncture needle 5 is provided with a forward rotation button and a reverse rotation button corresponding to the motor ; The forward and reverse rotation of the motor is controlled by the forward rotation button and the reverse rotation button, that is, the drug pushing and withdrawal operations of the syringe, so that the puncturer can operate alone, which improves the convenience of the application.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a puncture set special for nerve block. The puncture set comprises a power cavity, and a power structure is arranged on the power cavity; the power cavity is further connected with a fixing structure, the fixing structure is detachably connected with an injector, and the power structure is connected with a medicine pushing structure which drives the injector to push medicine and draw back; an infusion tube is detachably connected to the injector, and a puncture needle is connected to the infusion tube; the power structure comprises a driving assembly, and the driving assembly is connected with a speed adjusting assembly capable of adjusting the medicine pushing speed and the withdrawing speed of the medicine pushing structure; and the power cavity is further connected with an indicating structure corresponding to the injector, the indicating structure comprises a plurality of indicating blocks which synchronously and linearly move at equal intervals, and indicating pointers corresponding to the injector are arranged on the indicating blocks. The problems that existing nerve blocking operation is troublesome, and blocking fails are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a special puncture suit for nerve block. Background technique [0002] Ultrasound-guided nerve block technology has been widely used clinically. During the block operation, the operator usually holds an ultrasound probe for positioning with one hand, and the other hand holds a puncture needle to slowly puncture the target position under the guidance of ultrasound. However, in order to reduce pain during puncture and avoid accidental nerve injury, nerve block needles are designed to be very thin, so it is often difficult to obtain a clear image of the puncture needle, so a small amount of drug solution or saline is often injected quickly while inserting the needle , so that the block and dilation of the needle tip can be developed to determine the position of the needle tip; because the local anesthetic entering the blood will cause local anesthetic poisoning, ...
