AI Technical Summary

⚠Technical Problem

In existing techniques, the diameter of the puncture card is limited during cervical cerclage, making it difficult to precisely wrap the suture around the cervix, resulting in inconvenience and a longer operation time.

⚗Method used

Design a cervical cerclage device, including a base rod and a sleeve. The base rod is provided with a cerclage sleeve and an elastic buckle. The sleeve is provided with a limit hole and a locking hole. The sleeve is connected to the base rod by sliding and the position is locked by the elastic buckle, thereby constraining the diameter of the cerclage sleeve and simplifying the cerclage process.

🎯Benefits of technology

The procedure can be completed quickly, shortening the operation time, improving operational efficiency, and reducing the difficulty of operating the cervical cerclage device in the puncture card.

Abstract

This utility model discloses a cervical cerclage device and surgical instrument. The cervical cerclage device includes: a base rod with a cerclage sleeve fixedly mounted at one end and an elastic lock on the base rod; a sleeve slidably sleeved on the outside of the base rod, with a first limiting hole at one end of the sleeve corresponding to the cerclage sleeve, through which the cerclage sleeve passes; and several locking holes along the length of the sleeve, which are detachably engaged with the elastic lock. This utility model, by setting a base rod with a cerclage sleeve at one end and a sleeve with a first limiting hole at the other end, with the base rod and sleeve slidably connected and locked in position by the elastic lock, constrains the diameter of the cerclage sleeve through the first limiting hole. During cervical cerclage surgery, the cerclage sleeve is ligated to the cervix by pushing the sleeve, allowing for rapid completion of the procedure. After the predetermined time, the sleeve can be pulled back for easy removal. The device is easy to operate and significantly reduces the operation time.
