Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an aspirator capable of being combined with an energy instrument for use.
Background
The minimally invasive surgery is a minimally invasive surgery as the name implies, and particularly refers to a surgery performed by using modern medical instruments such as a laparoscope, a thoracoscope and the like and related equipment. The main advantages of minimally invasive surgery are: firstly, small wound: a tiny incision on the abdomen, 0.5cm to 1cm, basically no scar and a 'keyhole' name; secondly, pain is slight: the pain of the patient is small, the operation adopts intravenous anesthesia, and the patient completes the operation in a sleeping state; thirdly, fast recovery: greatly reduces the damage to the viscera and the interference on the functions of the viscera, and shortens the recovery time after the operation; fourthly, the hospitalization time is short: generally, the patient can get out of bed within 6-8 hours after operation, can eat food after 12-24 hours of anal exhaust, is discharged from hospital within 3-5 days, basically recovers after one week, and the cost is relatively reduced; fifthly, bleeding is less: almost no bleeding occurs during the operation. The minimally invasive surgery has clear visual field, the blood vessel treatment can be more delicate, and the adoption of advanced hemostatic instruments such as an ultrasonic knife and the like is helpful for reducing the amount of bleeding.
The industry of endoscopic minimally invasive surgery medical instruments is mainly promoted by the development of the medical technology level, and the industrial process of the industry is generally behind developed countries due to the late development of the domestic endoscopic minimally invasive surgery technology. The medical technology of developed countries such as Germany, Japan, United states and the like is in the leading position of the whole world, wherein the endoscopic minimally invasive surgery medical instrument obtains the brand influence of the international scope by the advanced processing capability, the leading technological level, the complete product series and the rapid product update. The international famous endoscope minimally invasive surgery medical instrument production enterprises represented by American Medtronic company (Medtronic), Johnson & Johnson company (Johnson), Olympus Japan (Olympus), Karl Storz Germany and the like occupy the leading position of the global endoscope minimally invasive surgery medical instrument market and the main share of the national endoscope minimally invasive surgery medical instrument market by providing products with high quality, ingenious structural design, high temperature and high pressure resistance and long service life. The development of medical instruments for endoscopic minimally invasive surgery in China has been over 30 years old, and with the gradual popularization of endoscopic minimally invasive surgery, the requirements of downstream markets on the surgical instruments are more and more vigorous. In the early development stage of the domestic endoscope minimally invasive surgery medical instrument industry, the development is comprehensively influenced by factors such as fund, brand, talents, experience and the like, most production enterprises are relatively small in scale, relatively weak in market competitiveness, and incapable of meeting clinical requirements in terms of production capacity and research and development technology level, so that downstream customers such as medical institutions and health service institutions import foreign products in a large quantity.
However, in recent years, the nation has great support for the medical instrument industry, various medical instrument enterprises are increasing research and development investment, domestic endoscope minimally invasive surgery medical instrument production enterprises are greatly developed, and market competitiveness is continuously enhanced.
At present, more imported medical instruments are still used in the field of endoscope minimally invasive surgery medical instruments in China. However, the price of imported medical equipment is high, and patients need to bear higher medical expenses, which is contrary to the policy of further reducing the medical expenses of patients in China. Therefore, the government of China actively encourages the research and development of domestic endoscopic minimally invasive surgery medical instruments. Although the current domestic endoscope minimally invasive surgery medical apparatus still has a certain gap with imported products in the aspects of stability, precision and the like, with further improvement and innovation of the technology, part of domestic products approach the imported products in the aspects of functions, quality and the like, and have obvious advantages in the aspect of price. 3 months 2015, State department issued a national medical and health services System planning outline (2015 + 2020), and proposed: the medical facility is guided to reasonably configure suitable equipment, so that the configuration level of domestic medical equipment is gradually improved, and the medical cost is reduced. With the strong support of the government, the price advantage of domestic endoscopic minimally invasive surgery medical instruments is certainly converted into competitive advantage. The method brings unprecedented development opportunities for domestic endoscope minimally invasive surgery medical instrument production enterprises.
The rapid development of modern medical technology has made the application of minimally invasive techniques in surgical diagnosis and treatment practical. The endoscope minimally invasive surgery has the advantages of small wound, short surgery time, quick postoperative rehabilitation, small mental burden of medical care personnel and the like. At present, the understanding of most hospital managers to the minimally invasive technology in China is also changing, and the technology gradually rises from a new technology to the science diagnosis and treatment concept level. The minimally invasive technology is being used by all hospitals as one of the core competitiveness of the intensive construction of the hospitals. The change of the minimally invasive technology for the hospital is not limited to the subject strategic level, and when the hospital managers and the industry manufacturers really fall the minimally invasive concept and technology, the application concept and the production mode of the minimally invasive technology are changed from 'taking the mechanism as the center' to 'taking the patient as the center', and the minimally invasive technology is bound to become the mainstream development direction of the future hospital. The endoscopic minimally invasive surgery, which is a widely adopted surgical method in the minimally invasive technology, will be adopted by more doctors and patients step by step.
In the traditional endoscopic surgery, because the number of incisions is limited, different instruments are required to be replaced to enter the body frequently, and the surgery efficiency is reduced. The energy apparatus and the suction apparatus are two indispensable important apparatuses in the endoscopic surgery, the energy apparatus is responsible for cutting, destroying and extracting human tissue structures, ultrasonic energy, electric energy and laser energy are converted into heat energy to treat human tissues, and a large amount of plasma substances can be generated under the condition of short time and high temperature and overflow along with blood and the like. At this time, the suction apparatus is required to continuously suck the residual blood and various gasified substances, so that the normal operation is not affected. It should be noted that the plasma substance generated by high temperature in the long-term inhalation operation process has health risk to the medical care personnel, and it is very important to improve the suction efficiency of the aspirator.
In conventional endoscopic surgery, a main surgeon typically holds an energy instrument to perform a surgical operation, and an assistant holds an aspirator to perform local suction on a wound or a wound surface. Two persons need to cooperate with one another to achieve a good suction effect, but even if the two persons are well matched, the two persons need to operate with two hands, so that the operation space of the incision is still very limited, and the operation is not favorable for efficiently completing the operation.
The common suction apparatus is made of metal or plastic material, usually in the form of straight tube, the suction nozzle and tube body are inserted into the incision, the tube tail is sleeved with a section of medical rubber tube, and is connected with a negative pressure system. The actual suction effect is greatly related to the pipe diameter and the pipe length of the aspirator, and the hardness, the length and the inner diameter of the rubber pipe. In actual use, the suction apparatus has large pipe diameter and short length, and the suction effect is better. The texture and size of the rubber tube connected with the suction apparatus often have great influence on the suction effect, but are always ignored in practical use.
