Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a thoracoscope operation aspirator.
Background
Lung Cancer is one of the most prevalent cancers in the world at present, and it is shown according to the statistical data published by the CA Cancer J Clin in 2018 that: the number of new lung cancer outbreaks in the world is nearly 210 million, accounting for 11.6% of 36 main malignant tumors; lung cancer is 176 million lethal, accounting for 18.4% of 36 major malignancies. The incidence and mortality of lung cancer are the first, and the life health of patients is seriously threatened.
With the current early screening and the improvement of health consciousness of people's physical examination, many lung cancers are detected in early stage. At present, a comprehensive treatment scheme mainly based on radical surgery is adopted for early-stage lung cancer patients. Many clinical studies have shown that early stage lung cancer patients have a better prognosis after receiving surgical treatment. At present, with the development of images and endoscope levels and the promotion of a minimally invasive surgical concept, particularly since the development of modern thoracoscopes in the 90 s, television-assisted thoracoscopic surgery (VATS) is continuously and innovatively developed, and the safety and effectiveness of VATS in treating lung cancer are generally determined, so that the VATS becomes one of conventional non-small cell lung cancer (NSCLC) treatment operations. The development of VATS has been further driven recently by the continued sophistication of instrumentation and VATS technology.
Common VATS is divided into a single hole (the lens and all operating instruments enter from a main incision of 3-4cm, the main knife is mainly operated by holding an electric hook or an ultrasonic knife with the right hand, the suction head with the left hand is used for sucking bleeding and smoke and assisting in exposing the surgical field, the camera with the right hand is used for providing the visual field with the assistant, the visual field is exposed with the assistance of the left hand), the hand-held surgical instrument comprises three types, namely a double-hole (a small incision of about 1cm is made for a lens to enter, and other instruments enter from independent incisions) and a three-hole (on the basis of the double-hole, another small incision of about 0.5cm is made for an aspirator to enter. the main knife holds an electric hook or an ultrasonic knife to carry out main operation on the right side, and the left hand holds the instrument to assist in exposing a surgical field. Among them, single-hole and three-hole are the mainstream modes of clinical thoracoscope operation at present.
In VATS, a negative pressure aspirator is of critical importance. For intraoperative hemorrhage, or smoke generated by high-temperature cutting of an electric knife and the like, the smoke is sucked from the visual field of an operator by a suction apparatus. In recent years, with the popularization and popularization of the one-way thoracoscopic surgery proposed by professor Liulunxu professor of western hospitals, the negative pressure suction apparatus becomes more important. Meanwhile, in VATS surgery, endoscopic forceps are required for operations such as clamping, pulling, tissue separation and the like.
Because the VATS incision is small, too many instruments cannot be inserted simultaneously; furthermore, VATS is typically performed by only two physicians, and there are limited instruments available at the same time. In actual operation, except for the endoscopic lens and the ring forceps for lifting the lung lobes and other instruments, only two instruments exist in the operation field at the same time: an electric hook or an ultrasonic knife held by the main knife for performing the main operation, and an aspirator held by the main knife or the assistant. The suction apparatus can help expose the operation field except the suction function, but the suction apparatus can not carry out fine operation such as centre gripping, then need take out the suction apparatus this moment, change into the clamp and operate, on the one hand the apparatus passes in and out the number of times and increases and can influence the operation rhythm, prolongs the operation time, on the other hand probably accompanies the local hemorrhage in the operation, if lose the suction function, then the hemorrhage can influence the operation field of vision, still can lead to the transfer chest even. Therefore, if the aspirator has a clamping function in addition to the existing functions of sucking blood and smoke, and pushing and lifting tissues, the VATS can be performed conveniently. The existing vacuum suction apparatus used in clinic only has a vacuum suction function and does not have a clamping function.
Because the incision of the thoracoscope operation is small, too many instruments cannot be simultaneously inserted, and in practical application, multiple instruments are often required to be matched and used alternately. The use of the independent thoracoscope negative pressure suction apparatus and the clamp requires repeated replacement of instruments, which not only prolongs the operation time, but also can lead to the incapability of timely handling emergency events such as bleeding and the like, and leads to unclear operation field and the like to influence the operation effect. Therefore, the development of a thoracoscope vacuum extractor surgical instrument with a clamping function is urgently needed.
Compared with the traditional apparatus, the suction head for thoracoscope surgery (patent number: CN210750453U) with clamping function invented by Zeng sword and other people has some disadvantages although the suction head has clamping and suction functions at the same time. Firstly, the instrument controls the opening and closing part at the far end through the annular switch at the proximal hand-held part, compared with the traditional forceps, the opening and closing degree of the forceps at the far end cannot be flexibly controlled by an operator, and the design of the annular switch is not beneficial to one-hand operation, so that the complexity of the operation is increased; secondly, the distal clamping part of the forceps does not adopt Debakey teeth, so that when fine tissues such as blood vessels are treated, the tissues can be damaged; finally, the distal negative pressure suction device of the instrument can only be used in a state that the distal end is closed, and cannot play a role in suction while clamping tissues.
