Problems solved by technology

Due to the non-adjustable length of the surgical electrode, this type of electrosurgical pen sometimes cannot meet the surgical requirements. Doctors can only use other surgical electrodes that meet the surgical requirements, or even replace different electrosurgical pens to meet the surgical requirements.
In addition, because shadowless lamps in the operating room are generally used for lighting during the operation, it is easy to form the disadvantage that the field of vision is too dark to affect the operation in complex deep operations and operations with narrow entrances.

Embodiment 1

[0016] Example 1: Such as figure 2 As shown, the surgical electrode telescopic structure 3 adopts a surgical electrode 7 with a certain length, the middle part of which is wrapped by an insulating protective layer 8, and the surgical electrode end 9 is fixedly connected to a four-piece or multi-piece elastic metal terminal 10 with good elasticity and conductivity. , Together constitute the telescopic component 11 of the telescopic structure. The part where the surgical electrode protrudes from the knife pen and is wrapped by the insulating protective layer is used as the force applying part of the stretched knife head. In addition, a fixed insulating knife pen cap 13 is installed at the end of the knife pen, and the insulating knife pen cap and the knife pen housing form the entire shell. The insulating knife-pen cap 13 extends toward the interior of the knife-pen and is fixedly connected to the metal sleeve 15. The metal sleeve 15 is connected to the knife and pen control ci...

Embodiment 2

[0017] Example 2: Such as image 3 As shown, the structure adopts a surgical electrode 22 of ordinary length. The end of the surgical electrode is riveted or connected by other means to a metal sleeve 23 with an inner diameter greater than the diameter of the surgical electrode. The metal sleeve 23 is wrapped with an insulating protective layer 24 to form a retractable structure. Telescopic parts. A fixed insulated knife cap 25 is installed at the end of the electric knife. The insulating knife and pen cap 25 extends toward the inside of the knife and pen to be fixedly connected to a metal tube 26, and the end of the metal tube 26 is connected to the knife and pen control circuit through a wire. The outside of the metal pipe is wrapped by an insulating protective layer 27, and the front end is fixedly connected with a multi-piece elastic metal terminal 28 to form a fixed part of a retractable structure. Insert the elastic metal terminal in the fixed part into the metal sleeve ...

Embodiment 3

[0018] Example 3: Such as Figure 4 with 5 As shown, the metal sleeve in Embodiment 2 is connected to the sliding button 31 on the outside of the electrosurgical pen through the clip 30. A slideway 32 of a certain length is opened in the middle under the shell of the knife pen. The slide button can move back and forth on the slideway to drive the cutter head to expand and contract.

Abstract

The invention discloses an illuminating electric pettifoggery with a contractive cutter bit. A pettifoggery control circuit is arranged in a pettifoggery casing body. The illuminating electric pettifoggery with the contractive cutter bit is characterized in that a surgery electrode contractive structure is arranged in the pettifoggery casing body. A light-emitting diode (LED) light source is arranged on the outer side of the front end of the pettifoggery casing. A power supply device is arranged beside the LED light source. The illuminating electric pettifoggery with the contractive cutter bit can illuminate and has the function of surgery electrode contraction. The surgery electrode contractive structure is additionally arranged in the electric pettifoggery.

Description

Technical field [0001] The invention relates to the field of electrosurgical instruments, and more specifically, is an electrosurgical high-frequency electrode used in connection with a host. Background technique [0002] Due to its functional and operational advantages, electrosurgical instruments are gradually replacing traditional scalpels. The electrosurgical pens currently used in hospitals include surgical electrodes, surgical handles, finger switches, surgical accessory cables, surgical connectors, etc. The length of the surgical electrodes is fixed and non-adjustable. In general, due to different types of surgery, different lesion sites and tissues, surgical electrodes of different functions and lengths are required. This type of electrosurgical pen cannot meet the surgical requirements because the length of the surgical electrode is not adjustable. Doctors can only meet the surgical requirements by replacing other surgical electrodes with a length that meets the needs o...
