Multifunctional endoscopy suction device

Abstract

The invention discloses a multifunctional cavity mirror suction device which comprises two parallel cavities, wherein one cavity is an electric coagulator slot, the other cavity is a suction cavity, the head end of the suction device is blunt, the end of the electric coagulator slot is provided with a fixing device used for fixing an electric coagulator which is inserted into the electric coagulator slot, and the end of the suction cavity is provided with a negative pressure connector which is connected to the negative pressure and a negative pressure regulator which is used for regulating the negative pressure. The multifunctional cavity mirror suction device can be used as a suction device, the electric coagulator (an electrostick, an electric hook, an electrotome and the like) used forthe cavity mirror can be arranged in the multifunctional cavity mirror suction device, the multifunctional cavity mirror suction device can also be used as a sheath tube for separating the electric coagulator from the incision tissues of a patient, and when the electric coagulator is removed, the multifunctional cavity mirror suction device can be used as a blunt explorative disassociation and suction device.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to a multifunctional endoscopic suction device, in particular to a multifunctional endoscopic suction device used in surgical endoscopic operations. Background technique [0002] With the advancement of medical technology, the use of laparoscopic surgery in surgery is becoming more and more common. It is a minimally invasive surgery, which has the advantages of significantly reducing trauma and quick recovery for patients. It mainly includes laparoscopy, thoracoscopic surgery, etc. . In laparoscopic surgery, a hole is made on the patient's abdomen or chest wall, a through tube is erected on the hole, and special surgical instruments are inserted into the patient's body for operation. Medical personnel often need to complete various actions, including blood sucking, smoking, etc. , electrocoagulation, cutting and stripping tissue, washing, scraping tissue, etc. Some of the above-me...

Problems solved by technology

At the same time, laparoscopic surgery is performed in a closed space, and the smoke or bleeding generated by the electrocoagulation equipment during the operation seriously hinders the operation field. Urgent problems to be solved in laparoscopic surgery

At present, the aspirator is usually placed through another surgical channel, and the assistant assists in the aspiration, or the suction is performed after withdrawing from the electrocoagulation equipment, which will inevitably increase the complexity of the operation and increase the time of the operation.

[0004] At present, some scholars have invented endoscopic electrotome with suction, which can achieve the effect of suction and electrotome at the same time. However, the electrotome and suction are fixed and cannot be adjusted arbitrarily. If you need to replace the electrocoagulation rod or electric hook, you need to replace it as a whole.

Some scholars have also designed a suction device that is buckled on the outside of the electric knife, but this also has the disadvantage that the appearance is not smooth enough, and it needs to be withdrawn as a whole when it is replaced, and it cannot be used in endoscopic surgery, nor can it be placed in the sheath of endoscopic surgery wounds
