Description
Technical Field
The invention relates to the technical field of hysteroscope electric excision surgical instruments, in particular to a bubble suction instrument for an electric excision surgery.
Background
The hysteroscope technology is a minimally invasive endoscope technology which utilizes a natural channel of a human body, namely vagina-cervix, adopts an external light source, optical fibers, electronic equipment and a uterus swelling medium, looks directly at pathological changes of the vagina, cervix, uterine cavity and uterine tube orifice and utilizes related instruments to perform operation. The hysteroscope technology has been developed for the first time in the 19 th century, gradually replaces the traditional operation by virtue of the advantages of wide adaptability, minimal invasion and the like, and brings revolutionary change to diagnosis and treatment of various intrauterine diseases. The hysteroscope technology has wide adaptation diseases, and is widely applied to clinic as a gynecological diagnosis and treatment routine. With the development of hysteroscopy, hysteroscopy and hysteroscopy procedures are considered the gold standards for the diagnosis and treatment of a variety of intrauterine diseases.
Hysteroscopic surgery plays a significant role in gynecological surgery. The number of hysteroscopic surgeries increases year by year, and thus, it is very important to prevent serious complications in the surgeries. With the popularization of hysteroscopy, the awareness of complications thereof is also gradually increased. Gas embolism is a sudden and potentially lethal complication of hysteroscopic surgery, the most risky hysteroscopic surgery is TCRA, which has a gas embolism incidence of about 4.48%, a TCRE of about 0.81%, a RCRM of about 0.75%, and a slightly lower TCRP risk of about 0.38%, but more evidence supports the subclinical incidence of gas embolism far beyond this.
A large amount of bubbles can be continuously generated in the hysteroscope electrostomy, and in addition, the uterine cavity is expanded, the operation in the uterine cavity damages the vein, and the blood sinus is opened, thereby creating conditions for gas to enter the blood vessel. The gas enters the blood circulation to form gas embolism, which causes blood circulation interruption, sudden cardiac death, or hypoxemia, pulmonary hypertension, or reversely embolism coronary artery and cerebral artery to cause cardiovascular and nervous system dysfunction.
The gas embolism is in a sudden onset, the treatment means is very limited, the fatality rate is high, so the gas embolism is seriously prevented. The primary measure of prevention is to prevent gas from entering the cervix or uterine cavity. Besides, the bubbles can further increase the difficulty of the operation and form serious gas embolism complications besides blocking the operation visual field. However, the current hysteroscope system is lack of a device for treating bubbles, the bubbles continuously generated by the electric cutter are accumulated in the uterine cavity, and the flow and the angle of input and output media are mainly adjusted by experience at present to impact and absorb the bubbles, so that the effect is limited, and the pressure stability in the uterine cavity is influenced. Bubbles generated in the hysteroscopy are mainly small connected bubbles or single large bubbles, so that the visual field of the operation is easily blocked, the operation difficulty is increased, an operator often needs to pause the operation and even take out hysteroscopy instruments to exhaust the bubbles, the operation time is increased, and the times of the instruments entering and exiting the uterine cavity are increased.
The operating principle of the resecting operation makes the bubble generation reduction basically impossible, and the existing hysteroscope apparatus does not have a bubble suction device, so that an operator needs to pause the operation and take out the hysteroscope apparatus to exhaust the bubbles. At present, no equipment specially used for processing bubbles in the hysteroscopy operation exists, the opening sizes of valves for inputting and outputting media are mainly controlled by hands of an operator, the requirements on the experience of the operator are high, the dependency on the experience of the operator is high, the skill of an expert is difficult to be taught to a new operator, and the effect of the expert every time can not be guaranteed. Moreover, the two valves are controlled independently, and both hands are needed to operate respectively, and the more common method for sucking and removing bubbles is to open the large input and output valves quickly and simultaneously, so that the difficulty of the respective operation of both hands is higher, and doctors are easy to fatigue and disperse energy.
