Embodiment Construction

[0025] The method of the present invention comprises the following steps: refer to figure 1 , figure 2 and image 3 shown;

[0026] (1) Before processing the syringe needle 26, the tail of the syringe needle 26 is fixedly connected to the injection needle fixing device 8 in the front section of the fourth servo motor 25 of the chipless automatic rolling device. The injection needle fixing device 8 is connected to the fourth servo The motor 25 is coaxial and connected with the motor shaft as a whole, so that the rotation of the syringe needle 26 and the rotation of the fourth servo motor 25 can be completely synchronized during the processing. The fourth servo motor 25 and the injection needle fixing device 8 are connected to the straight second linear guide pair 18 through the fixed motor connection seat 22, and the third servo motor 23 controls its lateral feed rate and moving speed. The amount of lateral feed is based on the structural size of the center distance of the ...

Abstract

The invention discloses a processing method of a bionic syringe needle and a dedicated processing device of the bionic syringe needle. The processing method comprises the following steps: before the processing, fixedly connecting the tail part of the syringe needle at a raised pole at the front section of a fixed device of a fourth servo motor of a chipless automatic rolling device, when a left die and a right die are close to the needle, rolling the needle step by step by utilizing the arc-shaped cutting edges of the dies with the rotation of the needle to deform the needle, so as to enable the needle to form the required curved surface, when the needle is fed transversely by one displacement, locking a transverse guide rail, and repeating the above steps to complete the micromachining of the non-smooth surface of the bionic painless needle. The processing method, disclosed by the invention, is chipless processing; through the processing method, the micromachining of different non-smooth surface forms of all bionic painless needles can be completed; in addition, as the special structural form is formed on the surface of the needle, the shock resisting capacity of the needle can be improved to certain degree, and the injection speed can be increased slightly. Through the processing method and the processing device, the strength of the needle can not be reduced, the needle is not broken off while injection is performed, the stimulation to nerves of the needle is smaller and the sense of pain is reduced while injection is performed.

Description

technical field [0001] The invention relates to a processing method of a bionic syringe needle and a special processing device. Background technique [0002] Injection is an indispensable and important method in clinical medicine, and painless injection is the dream of every medical staff and patient. The development of bionic painless syringe reduces injection resistance and makes injection achieve painless or pain-relieving effect. The bionic syringe is processed on the surface of the original syringe with bionic non-smooth shape, which belongs to micro-processing, and there is no better processing method at present. If laser processing is used, the strength of the injection needle will be greatly reduced due to the ablation and dandruff removal process, and the needle will easily break in the skin during injection, causing thrombus and infection. [0003] The existing processing methods are as follows: [0004] There are many kinds of processing methods in microfabricat...
