What are the processing elements that affect the anti-slip of the disposable trocar device

The anti-slip threads of trocars are mainly used to enhance the fixation force of the abdominal wall and avoid the sliding of the trocars during the operation, so as to improve the stability and safety of the operation, so what are the key points to pay attention to in the processing of anti-slip threads?

First, non-slip thread design: the shape of the non-slip thread design has a direct impact on its non-slip effect. Usually, the diameter of the upper part of each circle of the anti-slip thread is larger than the diameter of its lower part, forming an inverted tooth structure, in order to increase the friction with the abdominal wall tissues, to prevent slipping off. Pitch and tooth type: The choice of pitch and tooth type will also affect the effect of non-slip threads. Reasonable pitch and thread type design can ensure that the thread and the abdominal wall of the tissue of the close fit, improve the anti-slip performance.

Secondly, the mould structure: the design of the mould has an important influence on the processing quality of non-slip thread. Molds need to have reasonable demolding mechanism and parting surface design to ensure the consistency and stability of threads in the process of mould nut processing.

Thirdly ,the processing technology: for the higher precision requirements, surface roughness value requirements of small anti-slip thread, need to use fine turning process for processing auxiliary precision discharge EDM process. To ensure the accuracy and surface quality of the thread. In addition, the polishing process can further improve the surface quality of the non-slip threads and reduce the surface scratches and scrapes, thus helping to improve their non-slip performance. In the polishing process, it is necessary to protect the structural features at the tooth shape to avoid throwing deformation.

Fourth, cleanliness: the cleanliness of the production environment is crucial to the quality of disposable medical trocars. Anti-slip thread processing needs to be carried out in a clean environment to avoid the impact of pollution and impurities on the quality of the thread.

Temperature and humidity control: Appropriate temperature and humidity conditions ensure material stability and machining accuracy. Under high temperature and high humidity, the material may deform or expand, thus affecting the processing quality of anti-slip threads.

The factors affecting the processing of non-slip threads of disposable medical puncture instruments include material selection, thread design, processing technology, mould design and production environment, etc. Donho has summed up a wealth of experience in comprehensively considering and improvement these aspects in order to ensure the processing quality of non-slip threads.
