Background

Pain has been listed by modern medicine as the fifth vital sign following respiration, pulse, blood pressure, body temperature. Some chronic pain itself is also a disease (e.g. trigeminal neuralgia, postherpetic neuralgia, etc.). Chronic local pain can form complex local pain syndrome or central pain, so that common pain becomes very severe and difficult to treat, various complications are induced by dysfunction and reduced immunity of all systems of the body, and even the patients are disabled or endangered in life. Long-term pain not only severely affects the physical, psychological and social functioning of the patient, but also his family and even society. Providing treatment to all pain patients is a common goal of medical services in all countries. Medical staff in the pain department can treat various acute and chronic intractable pains and create painless and relaxed life for patients.

The pain department needs to use the needle sword when carrying out minimal access intervention operation, and the needle sword is mostly constituteed by needle handle and needle body, and it is internal that the needle handle is directly inserted the needle sword of needle body to patient's when using mostly directly handheld needle handle. Since the needle body of the needle knife is directly inserted into the body of the patient, the needle knife needs to be sterilized strictly during the production.

The present disinfection and sterilization mode for needle sword is mostly for soaking formula or spray sterilization, when adopting the soaking formula to disinfect, because the volume of needle sword is less, can simultaneously soak many needle swoves together, when many needle swoves together soak, then can lead to soaking the antiseptic solution of disinfecting and receive the pollution, thereby make the disinfection and sterilization effect to the needle sword not good, and because the needle sword is small, it is also very inconvenient when taking out after soaking the completion, current spraying sterilization equipment for needle sword is spraying when disinfecting to the needle sword simultaneously, same because the volume of needle sword is little, need place the needle sword on the drive belt, make it to have one side can contact with the drive belt and make when spraying the antiseptic solution, the antiseptic solution can't effectually contact with it.
