Special laparoscope nipper aspirator for hepatobiliary surgery

Abstract

The invention discloses a special laparoscope nipper aspirator for hepatobiliary surgery. The aspirator comprises a handle, a cavity, a spring, a piston block, a fixed shaft, a rotating handle, a one-way valve I, a one-way valve II, an inner cavity pipe, a positioning sleeve, a positioning pin, a clamp nozzle, an outer cavity pipe, an auxiliary pipe, a draw wire and a spring piece. By manual pressnegative-pressure suction type design, a medical worker can suck effusion or mist in a patient conveniently, the operation convenience is improved, besides, by single small-amplification controlled suction, the problem that traditional electric continuous negative-pressure suction causes over suction and affects surgery operation and safety is solved; and secondly, by the matching effect of a draw clamp type mechanism, lesion tissue in the patient can be rapidly clamped, multiple clinical demands are met. To sum up, by the aid of the product, the problem of operation trouble due to cooperation of multiple instruments traditionally is effectively solved, the surgery time is shortened, surgery operation is optimized, and the good promotion and application purposes are achieved finally.

Description

technical field [0001] The invention relates to a laparoscopic grasper, in particular to a laparoscopic aspirator with grasping forceps special for hepatobiliary surgery. Background technique [0002] Laparoscopic surgery has been widely used in hepatobiliary surgery, abdominal surgery, thoracic surgery, etc. due to its advantages of small trauma and quick recovery. Laparoscopic surgery is famous for its precision and minimal invasiveness. To observe and understand the adjoining relationship of abdominal viscera by using a microscope, so as to ensure safe and accurate tissue separation in the patient's body. [0003] According to the above, the current clinical traditional laparoscopic operating instruments are generally simple in structure. During the operation, in order to ensure the operation effect, it is necessary to suction and discharge the fluid and mist in the patient's body, and it is also necessary to effectively clamp the diseased tissue in the body. Therefore, ...

Problems solved by technology

[0003] According to the above, the current clinical traditional laparoscopic operating instruments are generally simple in structure. During the operation, in order to ensure the operation effect, it is necessary to suction and discharge the fluid and mist in the patient's body, and it is also necessary to effectively clamp the diseased tissue in the body. Therefore, at present, multiple groups of instruments need to be used interactively and replaced frequently in clinical practice, which not only affects the surgical field of view, is not conducive to the smooth operation of the operation, but also prolongs the operation time, increases the risk of injury to the patient's abdominal organs, and brings The operation of clinical surgery brings great hidden dangers. In view of the above defects, it is necessary to design a laparoscopic aspirator with grasping forceps for hepatobiliary surgery.
