Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an acupuncture knife device and an optical detection device. Background Art

[0002] Tenosynovitis is a common soft tissue disease, which is mainly manifested as inflammation of the tendons and tendon sheaths, and is common in joints such as the wrists and fingers. Traditional treatments include physical therapy, drug therapy, and surgical treatment. However, each method has its limitations and cannot provide comprehensive and effective treatment effects. Among them, physical therapy such as hot compresses and cold compresses can only temporarily relieve pain and cannot cure the cause. Although drug therapy can relieve pain and inflammation, long-term use may cause side effects, and drug therapy needs to continue for weeks or even months. Minimally invasive acupuncture surgery has become one of the important means of treating tenosynovitis due to its advantages such as less trauma and faster recovery.

[0003] Existing minimally invasive needle knife surgeries still face problems such as low surgical precision, inability to monitor in real time, and high wound recurrence rate during the operation. During the operation, doctors often rely on ultrasound imaging technology to locate the lesions, but due to the limitations of ultrasound imaging such as low resolution and susceptibility to tissue influence, the surgical effect is limited to a certain extent. At the same time, since real-time monitoring is not possible during the operation, doctors often rely on their own experience to operate, making it difficult to ensure surgical precision, and there is a risk of cutting too deep or too shallow. It can be seen that although surgical treatment can solve the problem more thoroughly, it relies too much on the doctor's personal experience, the imaging effect is not good, and it is easy to cause large trauma, long recovery time, and high risk of recurrence. However, the operation will cause certain trauma to the tissue, the postoperative recovery time is long, and there is a risk of complications such as infection and adhesion. Summary of the invention

[0004] Based on this, it is necessary to provide a needle knife device. The needle knife device of the present invention has the advantages of small trauma, fast recovery after surgery and basically no scar after surgery, etc. It can realize accurate diagnosis of diseases such as tenosynovitis, effectively improve the imaging resolution of the lesion site, and improve the success rate of fascia release.
