Hepatobiliary-surgery puncture system and use method thereof

Abstract

The invention discloses a hepatobiliary-surgery puncture system and a use method thereof. The system comprises a supporting base, an electric telescopic supporting rod and a puncture needle, wherein a movable connecting mechanism used for adjusting an azimuth angle of the puncture needle is connected between the puncture needle and the electric telescopic supporting rod; and a pressing mechanism used for fixing the movable connecting mechanism is arranged at the upper end of the electric telescopic supporting rod. The tail end of the puncture needle is connected with an external suction puncture mechanism. According to the hepatobiliary-surgery puncture system and the use method thereof, skin and flesh at a puncture position are conveniently pushed to the middle through a pushing and clamping plate, the skin and flesh hunch up and enter a suction cup, in a movement process of the pushing and clamping plate, a piston block in a piston air cylinder is linked to move, the piston air cylinder sucks air from the suction cup, thus, the suction cup sucks the skin and flesh at the position needing to be punctured, an external suction function is achieved, and therefore, the condition that the inner side of the puncture position is torn and injured due to the fact that skin and flesh tissues of a body of a patient are firstly pressed by the puncture needle and then punctured in a puncture process is avoided.

Description

technical field [0001] The invention relates to the technical field of puncture systems for hepatobiliary surgery, in particular to a puncture system for hepatobiliary surgery and a method for using the same. Background technique [0002] Hepatobiliary surgery generally requires puncture diagnosis and treatment during treatment. Generally, hepatobiliary puncture equipment mainly relies on needles to puncture the liver and gallbladder, and then extract tissue through the puncture needle, perform relevant tests or inject drugs through the puncture needle for treatment. [0003] The traditional hepatobiliary surgical puncture system for puncture has the following deficiencies: [0004] Generally, the puncture device in hepatobiliary surgery has a simple structure. After the puncture position is determined, it is directly inserted into the patient's body through the puncture needle. During the puncture, the inside of the skin and flesh tissue is easily torn due to the pulling f...

Problems solved by technology

[0004] Generally, the puncture device in hepatobiliary surgery has a simple structure. After the puncture position is determined, it is directly inserted into the patient's body through the puncture needle. During the puncture, the inside of the skin and flesh tissue is easily torn due to the pulling force, which increases the damage. After the puncture needle penetrates into the human body, the puncture needle needs to advance for a certain period to reach the position of the corresponding internal organs. Without a protective mechanism, it is easy to cause damage to the tissues passing by
