Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to an ovarian cyst puncture device. BACKGROUND

[0002] Ovarian cyst is a common disease in gynecological clinics and can occur in all age groups. After the occurrence of ovarian cyst, irregular abdominal pain and symptoms such as nausea and vomiting can occur, and part of the patients can further cause rupture and infection, which seriously threatens the life and health and safety of women, and therefore needs to be treated in time. Open surgery, cyst stripping under laparoscope, and ultrasound-guided puncture are effective schemes for the clinical treatment of ovarian cyst. Cyst stripping under laparoscope has multiple advantages, but the invasive operation of cyst stripping under laparoscope can affect the ovarian function. Ultrasound-guided puncture does not need to make an incision, can effectively avoid damage to the abdominal wall, is simple to operate, will not pull the surrounding tissues and organs, reduces surgical trauma and bleeding volume, is beneficial to postoperative recovery, shortens the intestinal exhaust time, and indirectly shortens the operation time and hospitalization period. Ultrasound-guided ovarian cyst puncture causes less damage to the ovarian cortex follicle and ovarian blood vessels and nerves, can effectively preserve the residual ovarian tissue, and ensures the ovarian blood supply to a certain extent.

[0003] Currently, COOK 16G puncture needles are used for puncture operation under the guidance of ultrasound in clinics. Although this method can perform ovarian cyst puncture, it still has the following shortcomings: first, the puncture needle cannot be fixed after entering the cyst cavity, and the puncture needle is easy to slip out during the suction of cyst fluid and the flushing of the cyst cavity, causing the suction and flushing to be not clean, and even causing the leakage of cyst fluid into the abdominal cavity to cause abdominal infection; and because the puncture needle is difficult to fix, the operation time is prolonged, and the operation difficulty is increased; second, the operator is required to be extremely high, the operator holds the puncture needle throughout the operation, adjusts the puncture angle at any time, and at the same time needs the assistant to complete the suction and flushing work; third, frequent puncture adjustment can increase the damage to the ovary and the body, and further increase the risk of infection.

[0004] Therefore, how to provide an ovarian cyst puncture device to efficiently achieve the puncture purpose of ovarian cyst, keep the puncture device stable after entering the cyst cavity, reduce the operation difficulty and operation time, and improve the operation success rate is a technical problem that those skilled in the art need to solve.
