A releasable and recoverable laparoscopic viscera lifting bag

Abstract

The invention discloses a stretchable laparoscopic visceral organ lifting bag. The lifting bag includes a sheath tube and a piston rod, the piston rod is connected with the inner side of the sheath tube in an inserted mode, one end of the piston rod is provided with a handle base, the end, away from the piston rod, of the handle base is provided with a connector, one side of the connector is provided with a valve, the end, away from the handle base, of the connector is communicated with a connecting pipe, an inner cavity is formed in the piston rod, one side of the lower end of the inner cavity is connected with an exhaust pipeline, rubber plugs are arranged on the outer wall of one end of the piston rod in surrounding mode, the upper end of the piston rod is fixedly connected with an annular fixing block, an annular clamping block is in sleeve joint with the inner wall of an annular fastening block, an lifting bag body is arranged between the annular clamping block and the annular fastening block, and a protection sleeve is arranged on the outer part of the lifting bag body. The stretchable laparoscopic visceral organ lifting bag is simple in structure and easy to operate, the position of the lifting bag body at visceral organs can be changed at any time through the piston rod, the lifting bag stretches and retracts freely, and the good supporting and cushioning effects are achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a releasable and recoverable laparoscopic viscera lifting bag. Background technique [0002] In laparoscopic liver surgery, the patient is in a supine position. The doctor needs to fully mobilize the liver and rotate the inferior vena cava as the axis to the left and upward to expose the hepatic parenchyma and inferior vena cava of the right posterior lobe of the liver. surgery for lesions. The traditional method is to put medical gloves into the abdominal cavity through the sheath, and fill the gloves with water through a suction device. After the gloves are filled with water, use surgical clips to clamp the opening, and place them under the viscera to elevate the viscera. At present, the Chinese patent with the application number 201220340057.2 discloses a laparoscopic uterus lifting fixer, which consists of a horizontal bar, a horizontal bar fixing tube, a sliding tub...

Problems solved by technology

At present, the Chinese patent with the application number 201220340057.2 discloses a laparoscopic uterus lifting fixer, which consists of a horizontal bar, a horizontal bar fixing tube, a sliding tube, a vertical bar, a lifting rod, a fixing screw, a vertical tube, and a uterine cup. Support structure, this method has a complex structure and requires time-consuming operations. Since long-distance operations are performed with long rod-shaped instruments inside the abdominal cavity, the requirements for doctors are very high, and the fixed position of the fixator cannot be changed at any time to adapt to different conditions. Elevate the distance, therefore, long-term use will cause some trouble to the doctor
