本发明涉及医疗器械技术领域，尤其涉及一种电凝手术器械。The invention relates to the technical field of medical instruments, in particular to an electrocoagulation surgical instrument.
背景技术Background technique
随着科学技术的发展，在保证安全、有效的前提下医疗器械正沿着手术创伤最小化的主流方向发展，促使实现相关操作的医疗器械不断追求更加微创的临床效果。腹腔镜手术在临床方面的应用已有几十年的历史，相对于传统手术具有创伤小、感染率低、术后恢复快等优点，在泌尿外科、妇科、腹部外科等领域已被广泛应用。腹腔镜手术是通过在患者腹部穿入2-5个腹腔镜穿刺器后向腹腔内注入CO2气体，使腹腔膨胀，内窥镜及医疗器械通过穿刺器通道进入人体腹腔，医生通过内窥镜反馈的图像观察患者腹腔内组织情况，通过操作医疗器械，实现组织的电凝、切割、冲洗以及缝合。With the development of science and technology, on the premise of ensuring safety and effectiveness, medical devices are developing along the mainstream direction of minimizing surgical trauma, prompting medical devices that realize related operations to pursue more minimally invasive clinical effects. Laparoscopic surgery has been used clinically for decades. Compared with traditional surgery, it has the advantages of less trauma, lower infection rate, and faster postoperative recovery. It has been widely used in urology, gynecology, and abdominal surgery. Laparoscopic surgery is to injectCO2 gas into the abdominal cavity after penetrating 2-5 laparoscopic trocars into the patient's abdomen to expand the abdominal cavity. The endoscope and medical instruments enter the human abdominal cavity through the puncture channel. Feedback images are used to observe the tissue conditions in the patient's abdominal cavity, and the electrocoagulation, cutting, flushing, and suturing of the tissue can be realized by operating medical instruments.
电凝切割器和冲洗吸引器为腹腔镜手术中的两种常用器械，电凝切割器可以进行组织的电凝止血和电凝切割，冲洗吸引器可以进行组织切口的冲洗、腔内残夜的吸除以及电凝烟雾的吸除。现有的电凝切割器和冲洗吸引器为两把独立的器械，当需要通过电凝切割器进行电凝操作时，腹腔内会不断的产生电凝烟雾，当烟雾凝集到一定程度，内窥镜反馈图像视野受影响，这时医生需要停止电凝，将电凝切割器抽离腹腔，并将冲洗吸引器伸入腹腔将烟雾吸出后，再将电凝切割器伸入腹腔继续电凝操作，此过程需要频繁地将电凝切割器和冲洗吸引器伸入和抽离腹腔，操作繁琐，手术效率低，且增加了患者手术感染风险。比如，在腹腔镜胆囊取石手术中，医生需要快速的将胆囊切破，并快速的将胆汁吸出体外，现有技术无法达到。Electrocoagulation cutter and flushing aspirator are two commonly used instruments in laparoscopic surgery. The electrocoagulation cutter can perform electrocoagulation for hemostasis and electrocoagulation cutting of tissues, and the flushing aspirator can perform tissue incision flushing, cavity residual night Suction and suction of electrocoagulation fumes. The existing electrocoagulation cutter and flushing aspirator are two independent devices. When the electrocoagulation operation needs to be performed through the electrocoagulation cutter, electrocoagulation smoke will be continuously generated in the abdominal cavity. When the smoke is coagulated to a certain extent, endoscopic The field of view of the mirror feedback image is affected. At this time, the doctor needs to stop the electrocoagulation, pull the electrocoagulation cutter out of the abdominal cavity, and extend the flushing suction device into the abdominal cavity to suck out the smoke, and then extend the electrocoagulation cutter into the abdominal cavity to continue the electrocoagulation operation , this process requires frequent insertion and withdrawal of electrocoagulation cutters and irrigation aspirators into and out of the abdominal cavity, which is cumbersome to operate, low in surgical efficiency, and increases the risk of surgical infection for patients. For example, in laparoscopic cholecystectomy, the doctor needs to cut the gallbladder quickly and suck the bile out of the body quickly, which cannot be achieved by the existing technology.
