Embodiment 1

[0044] Such as Figure 1-2 As shown, a midwifery forceps for obstetrics includes a forceps body, a forceps leaf arranged at the front end of the forceps body and used to enclose the fetal head, and a forceps handle arranged at the rear end of the forceps body. A coating layer 1 made of silicone-based siloxane / hydrophilic silicon dioxide polymer nanocomposite material.

[0045] Polydimethylsiloxane / hydrophilic silicon dioxide polymer nanocomposite material is used as the coating layer 1, which can increase the friction coefficient of the inner surface of the forceps blade and increase the maximum static friction force of the contact surface between the forceps blade and the fetal head, so that The fetal head is easier to fix in the forceps, reducing the difficulty of the operator's clamping force control, reducing the damage and deformation of the fetal head due to excessive clamping force and excessive compression, and increasing the friction can effectively prevent fetal head...

Abstract

The invention discloses a pair of delivery forceps for the obstetrics department and a preparation method of a coating layer for the delivery forceps for the obstetrics department. The pair of delivery forceps for the obstetrics department comprises a forceps body, forceps blades arranged at the front end of the forceps body and used for including a fetal head, and forceps handles arranged at therear end of the forceps body, and the inner side surfaces of the forceps blade are provided with coating layers prepared from polydimethylsiloxane / hydrophilic silica polymer nanocomposite material, wherein the coating layer is prepared through solution preparation, internal mold processing and compression molding. The pair of delivery forceps for the obstetrics department is used for solving the problems of fetal head slippery caused by poor control over delivery forceps clamping force or too large tensile force, reduction of fetal head compression injury due to too large clamping force and the like, and the pair of delivery forceps for the obstetrics department has the advantages of moderate compliance, simple structure, convenient use, safety, sanitation and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a method for preparing obstetric forceps and a coating layer applied to obstetric forceps. Background technique [0002] Forceps are a vaginal birthing instrument used during the second stage of labor to help expel the fetal head as quickly as possible. It was first invented by the Chamberlen family. After more than four centuries of evolution, most of the currently used clinical forceps are simpson forceps and kielland rotary forceps. The survey in my country from 2006 to 2010 shows that the average rate of vaginal midwifery is only 0.6% to 0.8%, of which forceps midwifery accounts for 61.6% (Zhou Yubo, Li Hongtian, Zhu Liping, et al. 1993-2010 Vaginal midwifery in some areas of China In 2010, the rate of assisted vaginal delivery in some parts of Europe ranged from 0.5% to 16.4%, with an average of 7.5% (Macfarlane A J, Blondel B, Mohangoo AD, et al. Wide diffe...
