Description

Marker pen for laparoscopic surgery

Technical Field

The utility model relates to the technical field of medical treatment, particularly, be a marker pen for laparoscopic surgery.

Background

Laparoscopic surgery is a procedure that utilizes a laparoscope and its associated instruments. The cold light source is used for providing illumination, the laparoscope lens is inserted into the abdominal cavity, and the digital camera technology is used for leading the image shot by the laparoscope lens to be transmitted to a post-stage signal processing system through an optical fiber and displaying the image on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument. The development of the laparoscopic surgery relieves the pain of the patient in operation, shortens the recovery period of the patient, relatively reduces the expense of the patient, and is a surgical project which is developed rapidly in recent years.

When a laparoscopic tumor operation is performed, the tumor needs to be marked under a laparoscope, such as tumor incisal margin marking, anastomotic stoma design marking, tumor marking positioning and operation design identification marking, so that subsequent operations can be performed conveniently, direct viewing of operation live broadcast and direct visualization in operation video learning are facilitated, an instrument for marking under the laparoscope does not exist at present, marking under the laparoscope is difficult, and the current common method is a 'electrotome scar' method (liver/kidney/spleen and other solid organs) or a 'suture' method (stomach intestine/bile duct and other cavity organs) for marking, so that the wound of a patient is increased, and the operation difficulty is increased.
