Description

Multifunctional electrotome pen

Technical Field

The utility model relates to a medical appliance, in particular to an electrotome pen, and particularly relates to a multifunctional electrotome with an extensible scalpel handle and the functions of smoking, bit replacement and the like.

Background

Clinical surgery is a complex and serious treatment technique, and when a conventional scalpel is used, bleeding often occurs at the affected part. Advances in technology have led to electrosurgery being used in today's surgery and becoming more and more accepted by physicians and patients. But meanwhile, the operation smoke generated in the operation process also brings serious health hidden trouble to medical staff. Surgical smoke refers to gaseous substances generated during surgery, also called aerosol, burning smoke, diathermy plume and the like, and is formed by destroying and vaporizing tissue proteins and fat by a high-frequency electric burning knife during surgery. The surgical smoke not only obstructs the view of the surgical personnel, but also releases toxic and harmful substances into the air. Can cause the operating room personnel to have symptoms such as headache, eye and mucosa inflammation, and the like, and can also have long-term potential harm to human health.

Surgical smoke is composed of 95% water or water vapor and 5% cellular debris present in particulate form. However, the particles less than 5% cause serious harm to human health due to operation smoke, and the particles mainly comprise the following components: blood and tissue debris, harmful chemicals, active viruses, active cells, inactive particles, mutation-inducing substances, 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 tips according to different operation depths in the operation, so that the operation time is prolonged, and the risk of infection and psychological burden are increased for patients. In order to reduce the harm of operation smoke to 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 improve the physical and psychological health of the operation room staff. Research and development personnel decide to develop the utility model of the electrosurgical ablation electrode with the functions of smoking, smoke discharging and stretching.

The prior art has the following defects:

1. the needle point is unprotected, and the extremely sharp needle point is likely to hurt a doctor or a patient

Accordingly, there is a need for an improved handle set.
