AI Technical Summary

Technical Problem

Existing medical suture barb hot-melt equipment has a complex structure and high cost, making it difficult to achieve high-precision, low-damage barb forming and consistent mass production.

Method used

The positioning component uses negative pressure to adsorb and position the suture, and combines it with a heat-melting component and a cutting component to process the barbs. The heat-melting component softens the suture and the cutting component cuts the barbs. When the cutting component retracts the blade, it makes the barbs form a vortex shape. The positioning component cools and shapes the barbs through a cooling tank.

Benefits of technology

It achieves high-precision, low-damage barb forming, ensuring smooth, burr-free cutting edges, improving the consistency and yield of mass production, and features a simple structure, easy operation, and low maintenance costs.

Abstract

This invention belongs to the field of medical suture technology, and particularly relates to a medical suture barb heat-fusion device, comprising a first traction component, a second traction component, a positioning component, a heat-fusion component, and a cutting component. The first and second traction components are used to drive the suture to linear horizontal movement and rotation from both ends. The positioning component provides effective positioning support for the linearly horizontally moving suture. The heat-fusion component softens the suture to a suitable degree. The cutting component cuts barbs on the softened suture. This invention has a simple structure, is easy to operate, and has low maintenance costs.
