Description

A smoking electric knife pen

technical field

The utility model relates to the field of medical equipment, in particular to a smoking electric knife pen for surgery.

Background technique

The use of the electrotome pen with the electrotome is a widely used instrument in surgical operations, and is used for electrocoagulation and electrocution in various surgical operations. Compared with the traditional surgical scalpel, the electric knife pen has the advantages of less blood loss and shorter operation time. However, during the operation of the electric knife pen, whether it is electrocoagulation or electrocution, a large amount of smelly smoke will be produced, which not only affects the surgical field of view, but also may cause virus infection due to inhalation of harmful smoke and smell by operating doctors and nurses, which is harmful to the operation. Doctors and nurses cause harm. In order to eliminate the smoke and ensure the health of the operating doctor, the smoke generated during the operation must be eliminated in time.

Most of the electric knife pens currently on the market do not have a smoking function, and the smoke generated during the operation must be removed in time through devices such as an external smoking pipe, which increases the workload of the operation. Nowadays, people have invented electric knife pens with smoking function, which combine the smoking function and electric cutting/coagulation function. As mentioned in US 6,149,648 and US 5,693,044, they are the existing smoking electric knife pens. The existing smoking electric knife pen is equipped with a flat cutter head, which can only be operated vertically, while horizontal operation can only be operated with the side hand or sideways at 90 degrees, which is easy to make the operator tired, especially in oblique cutting, it is necessary to perform circular operation In the surgery, the operation can only be performed by twisting the hand, and it cannot be done in one go.

With the continuous development and innovation of science and technology, the instruments in the field of modern medicine, especially in the field of surgery, are developing in the direction of simple structure, convenience and comfort, humanized operation, and ergonomics. This not only ensures the success of the operation, but also Surgery time is also shortened.
