Pulmonary vessel separation aspirator used in thoracoscope

Abstract

A pulmonary vessel separation aspirator used in a thoracoscope is characterized in that the pulmonary vessel separation aspirator is mainly formed by sequentially connecting a negative-pressure connector portion (1), a handheld portion (2), an aspiration tube portion (3) and an aspiration head (4) to form a whole, the inside of the negative-epressure connector portion (1), the inside of the handheld portion (2), the inside of the aspiration tube portion (3) and the inside of the aspiration head (4) form a through negative-pressure aspiration channel, multiple negative-pressure aspiration holes (5) are formed around the aspiration head (4), the aspiration tube portion (3) is formed by a first straight tube section (301) and a second straight tube section (301), the first straight tube section (301) and the second straight tube section (301) are crossed in space, the included angle alpha of the horizontal projections of the axes of the first straight tube section (301) and the second straight tube section (301) ranges from 140 degrees to 170 degrees, the first straight section is coaxially connected with the handheld portion (2), the aspiration head (4) is connected with a second straight connection line (302), and the included angle beta of the axes of the aspiration head (4) and the second straight connection line (302) ranges from 135 degrees to 160 degrees. The pulmonary vessel separation aspirator has the functions of an aspirator and can also be used in a pulmonary vessel separation operation.

Description

technical field [0001] The invention relates to a medical device, in particular to an aspirator used in conjunction with a thoracoscope, in particular to an aspirator for separating pulmonary vessels under the thoracoscope. Background technique [0002] At present, minimally invasive surgery is a new type of low-invasive surgery, and it is receiving more and more attention from patients' doctors, especially in thoracic surgery. Since not only tissue resection is required during thoracoscopic surgery, but also pulmonary vessel separation is required, it is difficult for the general negative pressure suction device to meet the requirements of blood vessel separation during tissue resection, especially the existing negative pressure suction device does not have auxiliary separation function, it needs to be equipped with corresponding surgical instruments, and the number of surgical instruments inserted into the thoracoscope at one time is very limited due to the influence o...

Problems solved by technology

[0003] The purpose of the present invention is to design a pulmonary vessel separation suction device under thoracoscope that can not only absorb but also help blood vessel separation in view of the problem that the existing thoracoscopic pulmonary vessel separation affects the operation efficiency due to the lack of an ideal negative pressure suction device.
