Description
Technical Field
The utility model belongs to electrotome pen field, concretely relates to bipolar electrotome pen.
Background
Some surgical sites have the characteristics of deep penetration, narrow entrance or narrow surgical field (such as cervix, laryngeal cavity and nasal cavity), the conventional coagulation instruments (such as bipolar forceps) are difficult to spread and are easy to cause unintentional thermal injury, some microsurgery needs to carry out punctiform intermittent coagulation on the surgical field, and the traditional coagulation instruments such as the bipolar forceps have the defect of fuzzy operation, namely, the coagulation action of each time cannot be ensured to be consistent, for example, the distance between two forceps tips cannot be ensured to be consistent during each coagulation. The inconsistent distance between the tweezers points just can lead to the resistance size of tissue to change between the tweezers points, can cause the nonconformity of blood coagulation effect under the condition that unable blood coagulation at every turn all finely tunes the host computer power according to tweezers point distance or resistance change accuracy, takes place the unnecessary damage. In addition, in the microsurgery in which the target is difficult to observe very little, there is also a risk that the two forceps tips touch accidentally to cause a short circuit.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, reasonable in design's bipolar electrotome pen.
The utility model provides a technical scheme is: a bipolar electric knife pen comprises an insulating handle and an electrode, wherein one end of the electrode is inserted into the inner side of the insulating handle, and the other end of the electrode extends out of the insulating handle;
