Description
Technical Field
The utility model relates to a medical treatment puncture ware field, more specifically relate to a fornix puncture ware behind vagina.
Background
Posterior fornix puncture is a diagnostic method for puncturing the lowest part of the pelvic cavity, namely the uterine rectum crater, through the posterior fornix. Plays an important role in the clear diagnosis of gynecological acute abdomen. Because the puncture has higher requirement on the compliance of patients and is an empirical and blind puncture operation, the puncture is easy to have the risks of false negative results, side injury and the like caused by puncture failure in clinical application, and has certain limitation.
The existing fornix vaginae puncture is mainly used for puncturing by using a tool formed by connecting an empty syringe and a No. 12 long needle head, and pelvic cavity effusion is sucked while withdrawing the needle after the puncture is successful. During the puncture process, the empty needle head and the injector need to be taken out respectively for connection. In the process, the puncture outfit may be polluted, and the situation that the connection between the syringe and the needle head is not tight may exist, so that the puncture outfit falls off or even a gap exists between the two, so that the liquid cannot be pumped out or falls from the gap, thereby causing pollution. Due to the loose connection of the common tools, poor compliance during the operation process and the limitation that a small amount of pelvic effusion is difficult to extract liquid, clinically when the vaginal fornix puncture is used, a patient is often evaluated to reduce misoperation, such as the need of re-inserting the needle caused by the fact that the needle is pulled out when the needle is mistakenly inserted into the cervix, the uterine cavity, the rectum or inserted into the uterine rectal fossa. This often results in no fluid being punctured, or in damage to the patient's uterine rectum, or puncturing blood, which affects gynecological diagnosis.
At present, no report of applying negative pressure suction to posterior fornix puncture exists, the problem of inconvenient operation can be solved by negative pressure suction abdominal cavity posterior fornix puncture, the package is disassembled, the direct automatic suction can be realized after the puncture is successful, the operations of connection, suction and needle withdrawal are not required to be completed firstly, whether the puncture is successful or not can be known, the accuracy of the puncture can be improved, the operation is simple and convenient, and the application of the negative pressure suction abdominal fornix puncture in clinic provides beneficial reference value for the diagnosis and timely treatment of gynecological diseases, particularly gynecological acute abdominal diseases.
