Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a needle-type common bile duct incision device with a suction function. Background Art

[0002] Laparoscopic surgery is a minimally invasive surgery with the characteristics of small surgical trauma and fast recovery, so it is currently a surgical method favored by many patients. It involves making several small incisions in different parts of the abdomen, inserting cameras and various special surgical instruments through these small incisions, and using various surgical instruments to perform operations outside the body to complete the surgery. Compared with traditional surgery, laparoscopic surgery has the advantages of less trauma, faster postoperative recovery, and smaller abdominal incision scars. At this stage, laparoscopic techniques are becoming more and more sophisticated, and laparoscopic instruments are constantly being improved, gradually bringing more and more laparoscopes into liver surgery. In hepatobiliary surgery, almost all types of hepatobiliary, pancreatic and spleen surgeries can now be performed under laparoscopy.

[0003] During laparoscopic common bile duct lithotomy, the common bile duct needs to be cut with an electric hook, and then a choledochoscope is inserted into the common bile duct to remove the stones under the choledochoscope. However, the front end of the existing electric hook is at a 90° angle and is relatively large. It cannot accurately cut the common bile duct during cutting, and repeated cutting can easily cause common bile duct stenosis. At the same time, smoke will be generated during the cutting and hemostasis process. Because the abdominal cavity is a relatively closed space during laparoscopic surgery, smoke is difficult to dissipate and can easily affect the surgical field of view. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide a needle-type common bile duct incision device with a suction function, which can accurately incise the entire layer of the common bile duct and solve the technical problem that smoke during surgery affects the surgical field of view.

[0005] An embodiment of the present application provides a needle-type common bile duct incision device with a suction function, comprising an operating handle, a long rod, and an electric cutting head, wherein the long rod is installed at one end of the operating handle, and the electric cutting head is installed on the long rod, an air suction port is provided on the front end of the long rod, an air suction channel is provided in the long rod and the operating handle, the air suction port is connected to the air suction channel, an air suction pipe is provided at one end of the operating handle away from the long rod, and the air suction pipe is connected to the air suction channel, a conductive wire is provided in the long rod and the operating handle, one end of the conductive wire is connected to the electric cutting head, and the other end of the conductive wire extends to the outside of the operating handle and is connected to a plug.

[0006] Preferably, a push switch is provided on the operating handle, and the push switch is used to control the connection and disconnection of the conductive wire.
