Description

Perfusion control device of hysteroscope uterus expansion instrument

Technical Field

The utility model relates to the field of medical equipment, specifically disclose a hysteroscope uterus expander perfusion control device.

Background

With the introduction of advanced technologies, minimally invasive concepts and minimally invasive surgery are gradually developed and warmed up. As an important component of minimally invasive surgery, the development of hysteroscopes changes the diagnosis and treatment pattern of traditional gynecological diseases, and the hysteroscope has the characteristics of small wound ratio, high titer ratio, rapid postoperative recovery, no uterus resection and the like which meet the physiological and psychological requirements of patients. The hysteroscope is a new and minimally invasive gynecological diagnosis and treatment technology, is a fiber light source endoscope used for examination and treatment in the uterine cavity, and comprises the hysteroscope, an energy system, a light source system, a perfusion system and an imaging system; the front part of the endoscope body enters the uterine cavity, and the endoscope body has an amplification effect on the observed part, so that the endoscope body is visually and accurately a preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions. The adequate dilation and the clarity and absence of blood in the uterine cavity are important conditions for examination and treatment, and therefore perfusion systems are particularly important in hysteroscopy and surgery.

In the using process, the upper end of the hysteroscope is connected with the uterus expanding medium, the lower end is connected with the water inlet of the hysteroscope instrument, and the water pipe needs ethylene oxide for sterilization, so that the cost is high, and one person can not realize one pipe. At present, a common practice is to use a sterile plastic protective sleeve clinically, but the use through the protective sleeve is relatively inconvenient. When a doctor operates, the main attention is focused on the display screen, if the water quantity is regulated, the operation is inconvenient, the operation time is prolonged, and sterile gloves are easy to pollute; the doctor generally controls the lens with the right hand and adjusts the water quantity with the left hand, and then needs another doctor to assist in fixing the cervix. However, the operation time is more than 1h, and the syndrome of excessive absorption of the perfusion fluid is easy to occur.

In order to solve the technical problem, the utility model provides a hysteroscope uterus expander perfusion control device.

The utility model adopts the technical proposal that: the perfusion control device of the hysteroscope uterus-expanding instrument comprises a hose, a needle head, a container, a switch device and a hysteroscope body; the hysteroscope body comprises a handle, an insertion tube, a water inlet and a water outlet; the water inlet is connected with the hose through a switch device; the switching device comprises a section of three-way pipe and a switch; the three-way pipe comprises a water inlet and two water outlets, the water inlet and one of the water outlets are arranged at an angle of 180 degrees, and the water inlet and the other water outlet are arranged at an angle of 90 degrees; the water inlet is connected with a hose, the other end of the hose is connected with a needle head, and the needle head is connected with a container of uterine distention medium; one water outlet of the three-way pipe is connected with a water inlet of the hysteroscope body, and the other water outlet of the three-way pipe is connected with a hole packer through threads; the switch comprises a handle and a plunger, the plunger is positioned in the three-way pipe and is of a hollow cylindrical structure, three through holes are formed in the periphery of the plunger, and an interval of 90 degrees is formed between every two through holes; when the two through holes which are 180 degrees correspond to the water inlet and the water outlet, the perfusion of the hysteroscope uterus-expanding instrument is realized.

The water inlet of the three-way pipe is hermetically sleeved with the metal connector of the hose through the connector; the water outlet of the three-way pipe is hermetically sleeved with the water inlet of the hysteroscope body through the connector.

During the use, the hysteroscope body of one-hand operation is operated, and switching device is in aseptic regional core department, and within the scope of one-hand operation, convenient operation through the fine setting handle, can adjust the angle of plunger, and then the through-hole on the regulation plunger and the water inlet on the three-way pipe and the corresponding position of delivery port to realize the water yield and adjust.

The utility model has the advantages that: the device can be used once, has low value and reduces the economic burden of patients; the device does not need to use a protective sleeve, has a small and convenient operation area range, can be controlled by a single hand, controls the lens and adjusts the water quantity by the right hand of a doctor, and saves manpower resources by fixing the cervix by the left hand; the control device is arranged at the core of the sterile area and is not easy to be polluted; the operation visual field is clearer; greatly shortening the operation time.
