AI Technical Summary

Technical Problem

In the existing technology, improper clamping during the electrolysis process causes uneven current density distribution of extra-long suture needles, resulting in color difference on the product surface and making it difficult to adapt to needles of different lengths.

Method used

An ultra-long, curvature-free suture needle electrolysis clamping tool is designed, which adopts a supporting beam and symmetrically arranged L-shaped clamping arms. The two L-shaped clamping arms clamp the two ends of the needle body to ensure uniform current distribution, and an inner recess is provided on the clamping arm to accommodate needles of different lengths.

Benefits of technology

The current is evenly distributed on the surface of the needle body, which improves the surface quality of the product. The clamping distance can be adjusted according to the needle length, which adapts to needles of different lengths and simplifies the operation process.

Description

Technical field:

[0001] The utility model relates to the technical field of medical needle body processing and manufacturing, in particular to an electrolytic clamping tool for an ultra-long, non-curved suture needle, which has a reasonable structure, is easy to operate, can adapt to needle bodies of different lengths and improve product quality. Background technology:

[0002] During the manufacturing process of medical needle products, electrolytic polishing is required due to the special requirements for the surface of suture needles. During the electrolysis process, if special types of extra-long suture needles are clamped in the middle, the surface quality of the clamping contacts will be defective. Specifically, the current density on one side of the needle body will be unevenly distributed due to clamping, the electrolysis effect will be poor, and ultimately cause color difference on the product surface. Summary of the invention:

[0003] In view of the shortcomings and deficiencies in the prior art, the utility model proposes an electrolytic clamping tool for an ultra-long, non-curved suture needle, which has a reasonable structure, is easy to operate, can adapt to needles of different lengths and improves product quality.

[0004] The utility model is achieved through the following measures:

[0005] An extra-long, curvature-free suture needle electrolysis clamping tool is provided with a supporting beam, the upper end of the supporting beam is connected to a vertical connecting rod, and is characterized in that a double-sided clamping assembly is provided below the supporting beam, and the double-sided clamping assembly includes L-shaped clamping arms symmetrically arranged on both sides below the supporting beam, the L-shaped clamping arms are placed inverted, and the horizontal section of the L-shaped clamping arm is connected to the supporting beam via a locking nut, and nut locking slots corresponding to the horizontal section of the L-shaped clamping arm are respectively provided on the left and right sides of the supporting beam, and the nut locking slots are strip-shaped slots.

[0006] In the present invention, two L-shaped clamping arms are arranged opposite to each other, and the vertical sections of the L-shaped clamping arms are provided with corresponding recessed portions for engaging the ends of the needle bodies to be processed. In order to improve the electrolytic treatment efficiency of the needle bodies, more than two recessed portions are provided on the vertical sections of the L-shaped clamping arms.

[0007] During use, the utility model is used for the electrolysis operation of an extra-long non-curved suture needle, and two symmetrically arranged L-shaped clamping arms are used to clamp the two ends, so that the current is distributed relatively evenly on the entire needle body, ensuring the surface quality of the entire needle body as much as possible. Since the clamping contacts are located at the needle tip and the needle tail, they can be easily eliminated through subsequent processing. At the same time, the spacing can be adjusted according to the needle length, and the applicability is better.

[0008] Compared with the prior art, the utility model has the obvious advantages of reasonable structure, simple operation and the like. Description of the drawings:

[0013] In the present invention, two L-shaped clamping arms 5 are arranged opposite to each other, and the vertical sections of the L-shaped clamping arms 5 are provided with corresponding inner recesses 5 for engaging the end of the needle body to be processed. In order to improve the electrolytic treatment efficiency of the needle body, more than two inner recesses 6 are provided on the vertical sections of the L-shaped clamping arms 5.
