Problems solved by technology
The light source electric knife pen in the prior art is designed with only one LED light source, the overall structure is not beautiful enough, the illumination is small, and the illumination is uneven
And it does not have the function of real-time charging, it needs to be charged by a battery
Since shadowless lamps are used for lighting in the operating room during the operation, the dark field of vision will affect the progress of the operation during complex operations or operations with small entrances.

Embodiment Construction
[0012] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:
[0013] Such as figure 1 The specific working principle of the retractable light source electrosurgical pen shown is: the high-frequency and high-voltage signal provided by the host of the electrotome is output through the head of the surgical electrode, and forms a circuit with the negative plate connected to the patient, and the high-current-density high The high-frequency current gathers at the head of the electrode and directly destroys the tissue at the point of contact with the effective electrode tip to perform electrocoagulation and electric cutting operations on the patient. The specific structure of the electric knife pen is: include the electric knife pen handle 4, one end of the e...

The invention discloses a telescopic light source electrosurgical pencil which comprises an electrosurgical pencil handle portion, one end of the electrosurgical pencil handle portion is connected with a cutting head, an LED lamp I and an LED lamp II are arranged on the two sides of the connecting position of the electrosurgical pencil handle portion and the cutting head, the LED lamp I and the LED lamp II are arranged on the electrosurgical pencil handle portion in a parallel mode, an electric resection switch and an electrocoagulation switch are arranged on the electrosurgical pencil handle portion, an LED lamp switch controlling work of the LED lamps is arranged at the other end of the electrosurgical pencil handle portion, an electric cable is further connected to the electrosurgical pencil handle portion, and a plug and a power adaptor connector which are connected with an electrotome main machine are connected to the electric cable. According to the telescopic light source electrosurgical pencil, the LED lamps arranged side by side are adopted in a mechanism of the electrosurgical pencil to carry out real-time illumination, the luminance of a surgical field is effectively improved, and convenience is brought to a surgery.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a retractable light source electric knife pen. Background technique [0002] The electrosurgical pen is widely used in surgical operations and is an electronic surgical instrument that can replace mechanical scalpels for tissue cutting. The light source electric knife pen in the prior art has only one LED light source in design, the overall structure is not beautiful enough, the illuminance is small, and the illumination is uneven. And it does not have the function of real-time charging, and a battery needs to be used to charge it. Since shadowless lamps are used for lighting in the operating room during the operation, the dark field of vision will affect the progress of the operation during complex operations or operations with small entrances. Contents of the invention [0003] According to the problems existing in the prior art, the present invention discloses a re...
