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.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 , 2 shown.

[0018] A thoracoscopic pulmonary vessel separation aspirator, which is mainly composed of a negative pressure joint part 1, a hand-held part 2, a suction tube part 3 and a suction head 4 which are sequentially connected as a whole, and a continuous negative pressure suction channel is formed inside them. The pressure passes through the negative pressure hose, one end is connected to the negative pressure source, and the other end is set on the anti-falling inverted cone structure 6 of the negative pressure joint part 1. The negative pressure hose should be an elastic medical hose with an inner diameter smaller than the outer diameter of the negative pressure joint part. . The inner and outer diameters of the suction tube 3 and the suction head 4 are preferably the same size. A plurality of negative pressure s...

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...
