Visible accurate local anesthetic doser for transumbilical endoscopic surgery

Abstract

The invention relates to the technical field of medical equipment and discloses a visible accurate local anesthetic doser for a transumbilical endoscopic surgery. The visible accurate local anestheticdoser comprises a spray rod, a handle is fixedly installed at the right end of the bottom surface of the spray rod, a base is fixedly installed on the bottom surface of an inner cavity of the handle,a miniature pressurizer is fixedly installed at the top of the base, a spray header is fixedly installed at the top of the spray rod, a medical camera is installed selectively on the top surface of the spray rod, or the spray rod is matched in use with other video shooting sticks in the transumbilical endoscopic surgery. According to the visible accurate local anesthetis doser for the transumbilical endoscopic surgery, the spray header and the miniature pressurizer are mutually matched, an agent on the left side of an extruding plate in the spray rod is scattered into a mist and sprayed on the surface of a tissue, so that the tissue rapidly absorbs the anesthetic, the postoperation pain of a patient is effectively alleviated, the problem that the local anesthetic cannot evenly diffuse orinfiltrate on the surrounding tissue as the pipe of the traditional peritoneoscope is relatively thick and a water outlet is excessively large, so that the practicality of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a visible and precise local anesthetic drug delivery device during laparoscopic surgery. Background technique [0002] Advances in technology have made it possible to perform surgery through smaller incisions. In this way, there is less damage to tissue than conventional surgery. Through the keyhole-sized incision, surgeons can insert tiny light sources, cameras, and surgical instruments. The surgeon guides the operation of the surgical instrument to perform the operation through the images transmitted to the monitor. When this surgery is performed in the abdominal cavity, it is called laparoscopic surgery, when it is performed in the joints, it is called arthroscopic surgery, when it is performed in the chest cavity, it is called thoracoscopic surgery, and so on. At the beginning and end of laparoscopic surgery, wounds in the patient's body, including viscera, disin...
