Description
Technical Field
The invention relates to the field of medical instruments, in particular to a suspension device for endoscopic surgery.
Background
With the advancement of medical technology, it has become practical to perform surgery through smaller incisions, and endoscopic surgery has been developed, which causes less trauma, less hospitalization of the patient, less post-operative pain, and less scarring than conventional surgery. The procedure is performed through a keyhole-sized incision and the surgeon inserts a tiny light source, camera and surgical instruments. The surgeon guides the operation of the surgical instruments to perform the procedure through the images transmitted to the monitor. Such a surgical operation is called laparoscopic when performed in the abdominal cavity and thoracoscopic when performed in the thoracic cavity. In endoscopic surgery, organs are often suspended for surgical operation, because thoracic and abdominal organs are arranged in multiple layers, for example, the front uterus needs to be suspended when rectal surgery is performed, and the front stomach and the omentum are required to be opened when pancreatic surgery is performed, so that the organs are often suspended during endoscopic surgery to expose the surgical field, thereby facilitating the operation of covered organs or tissues. The current common suspension mode is that a needle with silk thread is directly penetrated into the abdominal cavity from the outer side of the abdominal wall, the silk thread is penetrated below the organ, then the sewing needle turns to pass through the abdominal wall from the abdominal cavity to the outside of the abdominal cavity, then the silk thread is penetrated out of the abdominal wall and knotted outside the abdominal wall, and the knotting tightness is judged according to the degree of the suspended organ. The existing mode has large trauma to patients, the suture passes through the abdominal wall from the outside of the abdominal wall to the inside of the abdominal wall, the risk of skin infection of the patients is increased, the degree of traction can be adjusted only by adjusting the tightness of the suture, the adjustment range is limited, and the puncture is needed to be carried out again if the suspended position needs to be changed.
In order to solve the problems caused by the conventional suspension devices, for example, CN204744271U discloses a liver suspension device for laparoscopic surgery, which requires the separation of coronary ligaments around the liver, which may damage blood vessels and lymphatic vessels around the liver, and which suspends only the middle position of the left lobe of the liver, so that the left free surface of the left lobe of the liver is still in a sagging state, which is not good in appearance. Patent document CN111388032A discloses an organ suspension device for endoscopic surgery, which uses a flexible band-shaped film having a width of at least 0.8cm, and ensures that the flexible band-shaped film is spread in the width direction as much as possible by an elastic edge, thereby increasing the contact area with the organ during suspension, enabling continuous and stable pulling of large tissues such as the liver, enabling efficient and clear exposure of the surgical field, and causing little stress on the pulled tissues, thereby preventing damage to the tissues or organs. Meanwhile, the base suspension band and one or more additional suspension bands are connected in a pivoting mode, so that the same suspension device can be repeatedly used in the same operation, and the suspension device can be suitable for visceral organs and tissues with different specifications and shapes. The suspension device in the prior art has the same problems in actual operation, namely, the suspension wire or the strip-shaped film is pulled out of the thoracic cavity through the thoracic puncture needle, and is knotted and fixed on the external fixing device, so that the liver is suspended in the thoracic cavity to fully expose the operation visual field, and in the operation process, the steps of thoracic puncture and knotting of a doctor are added, and an external additional fixing device is also added. When the liver is hung on the suspension line or the strip-shaped film, the stress surface of the suspension line or the strip-shaped film is very narrow, and when the young liver is hung on the line or the strip, the liver operation is inevitably carried out after long-time operation.
