It relates to the device.

In general, endoscopic (or laparoscopic) surgery is a minimal invasive surgery and has been rapidly developing in recent years due to the advantages of reducing pain, infection, wounds, and hospital stay.

During surgical treatment, in particular, an electric surgical device or an electric scalpel (hereinafter referred to as an electrode) is used to remove biological tissue from a specific patient area by inserting it into a patient's abdomen. In such an electrode, the metal tip connected to the wire is attached to the end, and the metal tip generates high frequency when electricity is passed through the wire, and heat is generated on the surface of the high frequency tip. The tissue is burned and removed. In addition, pads or copper plates are laid under the patient's body.

Meanwhile, various foreign substances, blood, and other foreign substances are mixed during patient surgery to generate contaminants, and such contaminants are removed using a separate washing device or a device that sucks in by inhaling is used.

That is, during laparoscopic surgery, laparoscopic suction is a surgical instrument for supplying a cleaning solution to clean the patient's surgical site and discharging the contaminant to the outside of the patient's body in order to remove the contaminant after washing the patient's surgical site. -A laparoscopic suction and irrigation apparatus is used.

A general laparoscopic suction-cleaning device includes an insertion tube inserted into the patient's body, an appliance body having a mixing chamber connected to the insertion tube, a cleaning passage connected to the mixing chamber to supply a cleaning solution into the patient's body, and the And a discharge passage which is connected to the mixing chamber separately from the washing passage and discharges contaminants to the outside of the patient's body.

In addition, the laparoscopic suction-cleaning mechanism includes a washing passage control valve installed only on the washing passage and a discharge passage control valve installed only on the discharge passage.

Conventional medical suction and cleaning devices require repetitive manipulation of the insertion and extraction of the metal tip during surgery, but it is not easy to operate the insertion and extraction of the metal tip with one or both hands, and the operation of the cleaning valve and the suction valve is also difficult. It is not easy, and there is a problem that the operation time is increased, the user's discomfort is caused, and other harm or damage to the patient's body may be inflicted as the cleaning liquid supply or the contaminant suction by the operation of the valve is not effectively performed. .

In addition, the conventional medical stone and cleaning device cannot accurately and precisely manipulate the metal tip due to the difficulty of such manipulation, and thus the area to be removed with the metal tip cannot be accurately removed, reducing the precision and safety of surgery, and reducing the cost of surgery. There was an increasing problem.

Moreover, the conventional medical washing and washing apparatus has a problem in that the recovery time for the patient increases, resulting in an increase in medical cost, increased discomfort for the patient, and inability to promote rapid recovery of the patient.

In addition, conventional medical suction and cleaning devices increase manufacturing cost and manufacturing time, and decrease productivity, resulting in consumer dissatisfaction.
