AI Technical Summary
Technical Problem
Current amniocentesis positioning methods rely on electronic devices, which are susceptible to electromagnetic interference, and the mother's breathing can cause positioning deviations, affecting the surgical process.
Method used
An adaptive contour sensing mechanism is used to mechanically sense the contour of the mother's uterus. Combined with an adaptive angle adjustment mechanism and a puncture needle guide mechanism, it ensures that the puncture angle is perpendicular to the uterus and avoids positioning deviation.
Benefits of technology
It enables adaptive positioning based on the mother's body posture without relying on electronic devices, ensuring accurate puncture angle and improving the reliability and efficiency of the surgery.

Abstract
The invention belongs to the technical field of medical instruments, and particularly relates to an amniotic fluid puncture positioning device used in an antenatal diagnosis center, which comprises a support mechanism, a self-adaptive contour sensing mechanism, a self-adaptive angle adjusting mechanism and a puncture needle inserting guide mechanism, the puncture position is determined; when the self-adaptive angle adjusting mechanism works, the puncture angle is always perpendicular to the uterine amniotic fluid position of a puerpera; the puncture needle inserting guide mechanism has a first state when the puncture needle cannot be inserted due to locking and a second state when the puncture needle is conveniently inserted after locking is released, and when the self-adaptive angle adjusting mechanism works to enable the puncture angle to be perpendicular to the uterus of the puerpera, the puncture needle inserting guide mechanism is automatically driven to be switched from the first state to the second state; the problems that in the positioning process, electronic equipment is excessively relied on, self-adaptive positioning cannot be carried out according to the body posture of a puerpera, and normal operation of a puncture operation is affected are solved.
