Novel single-pole and double-pole mixed mode surgical ablation electrode with smoke suction measurement function

Abstract

The invention discloses a novel single-pole and double-pole mixed mode surgical ablation electrode with a smoke suction measurement function. The novel single-pole and double-pole mixed mode surgicalablation electrode comprises a handle assembly, a tool bit assembly, a tool bar assembly and an electrode system. The surgical ablation electrode in the single-pole and double-pole mixed mode has a single-pole electrocoagulation electroexcision mode and a double-pole electrocoagulation mode at the same time. A single-pole instrument and a double-pole instrument do not need to be replaced frequently in the operation process. efficient separation can be achieved. Bleeding can be stopped in time. In addition, all keys are designed on the handle, the operation usability can be greatly improved, and the operation time is obviously saved. A smoke exhaust assembly can rapidly and efficiently suck smoke generated in the surgical operation, which greatly reduces harm of the surgical smoke to doctors and nurses. If endoscopic surgery is carried out, the smoke suction frequency and the scrubbing frequency of an endoscope lens are greatly reduced. The surgery time is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, more specifically, to a single-type single-bipolar mixed-mode surgical ablation electrode with smoking measurement function. Background technique [0002] As a basic surgical energy instrument, high-frequency electrosurgical instruments are widely used in various clinical surgical procedures, and their status in open surgery is unshakable. Although in the past two decades, the promotion of the ultrasonic knife has allowed it to occupy a place in endoscopic surgery, but the monopolar coagulation hook, monopolar electric scissors (such as used in the da Vinci robot), bipolar High-frequency electrosurgical instruments such as electrocoagulation (such as Ligasure, 100-gram forceps) are also developing rapidly, and are also widely used in endoscopic minimally invasive surgery. The unipolar high-frequency ablation electrodes routinely used clinically (including common surgical electric kn...

Problems solved by technology

[0003] The disadvantages of high-frequency electrosurgical instruments currently on the market are: 1. The mechanical integration of monopolar and bipolar ablation electrodes is not integrated. It is easy to pollute the surgical field of view due to untimely hemostasis; 2. The high-frequency electrosurgical instrument burns the tissue with heat to stop bleeding and cuts to vaporize the tissue liquid. The vaporized tissue produces a large amount of smoke, and the smoke contains a large amount of toxic gas. In open surgery, it has a great impact on the health of doctors and nurses on the operating table; and in laparoscopic minimally invasive surgery, it is very easy to atomize and pollute the lens of the endoscope, which will affect the observation of the endoscope, and frequent smoking Ventilating or scrubbing the lens seriously affects the progress of the operation, which is not conducive to improving the safety and efficiency of the operation; 3. Most of the cutter heads of the existing bipolar ablation electrodes are straight. When the angle is small, it is difficult to observe the operation of the cutter head; in addition, in open or endoscopic surgery, the cutter head of most monopolar high-frequency electrosurgical instruments has no protective layer, and the entire metal part is exposed to the surgical target area Besides, during surgical operations, especially when performing delicate operations such as paravascular lymph node dissection, the over-exposed part of the knife head is easy to accidentally injure the surrounding tissues
