Liver lobe exposure device in laparoscopic surgery

Abstract

The liver lobe exposure device comprises an inner tube body, an outer tube body and a bag body, the inner tube body and the outer tube body are mutually sleeved and slide, the bag body is connected with one end of the inner tube body, the bag body is controlled to stretch out or retract to one end of the outer tube body when the inner tube body slides in a reciprocating mode, and the other end of the inner tube body is connected with an external air source or a water source to supply air or water to the bag body. The capsule body is expanded to form an ellipsoid; when the bag body contracts and is contained in the outer tube body, the bag body is inserted into a wound of a patient through the hard outer tube body until the end portion of the outer tube body is in place. When the bag body extends out of the outer tube body and is expanded and formed, tissues on two sides are separated in the body of a patient; the outer tube body is further sleeved with a limiting assembly in a sliding mode, the limiting assembly is externally connected with an external air source, the limiting assembly is in place when sliding to the wound of the patient, the limiting assembly is limited to the outer tube body after being ventilated and expanded inwards, and the limiting assembly is limited to the wound of the patient after being expanded outwards. The bag body can be inserted conveniently, the whole structure is limited with a wound of a human body, and the use safety is improved.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a liver lobe exposure device in laparoscopic surgery. Background technique [0002] During laparoscopic surgery, especially during laparoscopic right hepatectomy, because the right liver is close to the posterior abdominal wall, it is very difficult to expose, which increases the surgical risk and operation time. Therefore, during the operation, a filler can be placed in the posterior space of the liver to cushion the liver, so that the liver lobe can be placed on the anterior side of the abdominal cavity, so as to reduce the difficulty of the operation. The filler can be placed into the body from the wound in the form of a balloon or a water balloon, and then ventilated or watered to support the sac-like structure. However, if the sac-like structure is displaced during the operation, it may change the shape of the liver. The doctor who is operating will cause trouble, and it may bring th...

AI Technical Summary

Problems solved by technology

The filler can be inserted into the body from the wound in the form of an air bag or a water bag, and then ventilated or watered to prop up the sac-shaped structure. However, if the sac-shaped structure is displaced during the operation, the shape of the liver may be changed. The doctor who is performing the operation brings trouble, and it is more likely to bring the risk of accidental injury during the resection process
