Description
Technical Field
The invention relates to a medical instrument, in particular to an electrotome pen, and specifically relates to a multifunctional electrotome with a surgical knife handle capable of being extended and simultaneously having the functions of smoking, tool bit replacement and the like.
Background
Clinical surgery is a complex and serious treatment technique, and when a conventional scalpel is used, bleeding is often caused at the affected part. Advances in technology have led to electrosurgery being used in today's surgical procedures and being increasingly accepted by doctors and patients. But the surgical smoke generated in the surgical process brings serious health hidden trouble to the medical staff. Surgical smoke refers to gaseous substances generated during surgery, also known as aerosols, glowing smoke, diathermy plumes, etc., that are formed during surgery by the destruction and vaporization of tissue proteins and fat by high frequency electrocautery knives. The surgical smoke not only obstructs the view of the operator, but also releases toxic and harmful substances into the air. Can cause symptoms such as headache, eye and mucosa inflammation and the like of operating room personnel, and can also cause long-term potential harm to human health.
Surgical smoke consists of 95% water or steam and 5% cell debris in the form of particles. However, it is these 5% less particles that cause serious harm to human health from surgical smoke, and these particles mainly contain the following components: blood and tissue fragments, harmful chemical components, active viruses, active cells, inactive particles, substances inducing mutation, and the like. A large number of medical personnel are exposed to surgical smoke, including surgeons, nurses, anesthesiologists, and the like. In addition, doctors often replace the ablation electrode head according to different operation depths in operation, so that operation time is prolonged, and risks and psychological burden of infection can be increased for patients. In order to reduce the harm of the operation smoke to the medical staff, ensure the health and safety of the medical staff and patients, provide a healthy environment for the operation room work of the medical staff, and promote the physical and mental health of the staff in the operation room. We decide to develop the electrode for ablation of electrosurgery with the functions of smoke sucking, smoke exhausting and telescoping.
The prior art has the following disadvantages:
1. the needle tip is unprotected and a very sharp needle tip is likely to injure a doctor or a patient
2. Because the ablation electrode tip and the smoke tube are integrated, the ablation electrode tip cannot be replaced,
3. Has simple smoking function, and the fixed length can not be adjusted to seriously affect the operation.
Accordingly, there is a need for an improved handle arrangement.
