Description

Delivery room delivery is with midwifery device Technical Field The invention relates to the technical field of delivery forceps, in particular to a delivery assisting device for delivery in a delivery room. Background The delivery forceps are a tool used for helping the fetus to deliver, and are mainly used when the fetal head is low and auxiliary is needed. The handling of the forceps is more difficult than with another tool called a "fetal head aspirator", requiring special training by the physician. The biomedical engineering industry aims to improve the safety and success rate of operation by continuously improving the design of obstetric forceps and developing a training simulator. If improperly used, the woman or baby may be injured, so it is now common for the physician to consider use without success in the fetal head aspiration procedure. During operation, a doctor firstly lightly puts the left blade of the obstetric forceps on the left side of the pelvic cavity of a puerpera, then puts the right blade of the obstetric forceps, then folds the two blades in an aligned mode, and finally slowly pulls the obstetric forceps during uterine contraction to help the fetal head to be delivered. The patent publication No. CN210228290U discloses obstetric forceps for obstetric department, which comprises a forceps body, forceps leaves arranged at the front end of the forceps body and used for wrapping a fetal head, and forceps handles arranged at the rear end of the forceps body, wherein a film coating layer made of polydimethylsiloxane/hydrophilic silica polymer nanocomposite is arranged on the surface of the forceps She Nace. The clamping force control device is used for solving the problems of fetal head slipping caused by poor clamping force control or overlarge tension of the obstetric forceps, and the like, and reducing the fetal head compression damage caused by overlarge clamping force. The prior art has the following defects: The traditional obstetric forceps mostly adopts an integral rigid structure, and in the clamping and pulling processes, metal forceps leaves are mainly relied on to directly act on the fetal head, and the situations of partial stress bias and insufficient fitting degree are easy to occur due to lack of flexible transition and self-adaptive fitting design. In the actual pulling process, the clamping force is difficult to automatically adjust according to the traction force in the traditional structure, the stability mainly depends on experience of operators, and the problem that the clamping force is not matched with the actual demand easily occurs. Meanwhile, the elastic buffer structure of the conventional obstetric forceps is simple, only a single elastic element is generally adopted, hierarchical buffer and overload protection are difficult to realize, and a lifting space is still reserved in terms of safety and controllability. Although some similar products have corresponding locking structures, there is still an optimization space in terms of operation convenience, response synchronism and matching precision with internal movable parts, and it is difficult to realize the integrated synergistic effect of soft clamping, self-adaptive locking and quick locking. Disclosure of Invention In view of the above problems in the prior art, a delivery assisting device for delivery in a delivery room is provided. The application provides a delivery assisting device for delivery in a delivery room, which aims to effectively prevent slipping in the delivery assisting and pulling process and ensure stable and reliable delivery operation. The delivery assisting device comprises a left clamp arm and a right clamp arm which are hinged in a crossing manner, wherein the front end of the clamp arm is provided with a clamp blade, the rear end of the clamp arm is provided with a clamp handle, the clamping side of the clamp blade is provided with at least two sliding grooves, movable auxiliary blades are arranged in the sliding grooves in a sliding manner, the clamping surfaces of the movable auxiliary blades are linearly provided with a plurality of suckers, the opposite surfaces of the clamping surfaces of the movable auxiliary blades are provided with a plurality of first wedge blocks at equal intervals, the bottom of the sliding groove is provided with a plurality of second wedge blocks, and the second wedge blocks correspond to the inclined surfaces of the first wedge blocks and have opposite directions. Furthermore, the clamp blade is in a drop shape, the narrow end of the clamp blade is connected with the clamp handle, and the middle part of the clamp blade is hollowed out. Further, the clamping surface of the movable auxiliary blade is linearly provided with a plurality of rotating grooves, and a plurality of suckers are respectively hinged in the rotating grooves. Further, the front end of sliding tray is provided with the spring holder, and the joint has long spring and short spring in t
