Supporting design and scheme of pneumoperitoneum needle structure parts

Pneumoperitoneum needle in fact, as a rule, pneumoperitoneum needle products manufacturing we all around the doctor surgery procedures for the center to think about things, the doctor at the time of surgery is usually right hand push pin habits, pneumoperitoneum needle need after abdominal fascia and peritoneum, so the toughness of the needle and piercing force is very important, puncture force is bad influence to the patient's pain, because doctors need to increase the thrust of mandatory push pin, here, sinowares technology team for pneumoperitoneum needle product design and manufacturing has the following Suggestions:

1. The manufacturing process of pneumatic abdomen needle fine metal pipe body material is basically a strip welding process by manufacturers in China, so the pipe body fracture and pressure test and inspection are essential in product design.

2. The puncture edge of the external tube of pneumoperitoneum needle is the best guarantee of puncture force for the Angle. However, as for the problems of our brothers above, the small workshops of several people can hardly guarantee the puncture force detection and precision Angle deviation.

3. Smooth structure of the head of the needle inside the pneumoperitoneum needle, which is the key. The inner hole needs to be clean.

4, pneumatic abdomen needle handle injection parts, in fact, said our brothers said that the gel slide and his choice of plastic type and structure has a great relationship, some plastic in the high-temperature disinfection environment will be deformed and fall off, in addition to the structure, try to add a sandblasting relief.There was no torque, but our slight intervention prevented other problems.Of course, the handle also has metal, metal structure in the welding process, the welding material and firmness must pass strict inspection!

5. We must not ignore the strength of pneumoneitoneal needle. In puncture, the strength of doctors and the response strength of fascia will directly lead to the overall deformation and flat shift direction.

6. All material control, data tracing, manufacturing environment, cleaning environment, packaging environment and so on must be strictly checked in accordance with ISO13485 quality system requirements, and the departments in each link need strict training.
