PCA Self-Controlled Analgesia Technology When a patient feels pain, he or she can feel pain relief or no pain at all quickly by simply pressing a button. It achieves the best effect with the smallest dose and the least side effects, enabling individualized treatment. Nerve Destruction Technology Injecting drugs into the nerve surrounding to make the pain nerve lose conduction and achieve long-term or permanent analgesia. Applicable to: patients with various kinds of intractable cancer pain or neuralgia. Radiofrequency thermocoagulation therapy uses temperature control to block nerve conduction to achieve long-term or permanent pain relief. It is suitable for patients with neuralgia or cancer pain who have failed to receive conservative treatment. Good controllability and high safety. Intrathecal drug infusion technique The drug is directly applied to the spinal cord and brain, and the dose of the drug applied is only 1/300 of the dose needed for oral administration, avoiding the toxic side effects caused by large amounts of oral medication. It is safe, minimally invasive, highly effective and with few complications. It is suitable for patients with cancer pain and chronic intractable pain whose traditional treatment methods are ineffective or who cannot tolerate the side effects of drug therapy, and has a high success rate. It can also be applied to patients with long-term intrathecal drug chemotherapy. Spinal cord electrical stimulation technique The spinal cord stimulation electrodes are implanted in the corresponding spinal cord stages, and the spinal cord stimulation is performed by sending electrical stimulation waves through the connected stimulator to achieve pain relief. It is suitable for patients with intractable pain for whom conventional treatment is ineffective.
