The utility model relates to an eye-use PVA absorbent hemostatic cotton swab, which comprises a cotton swab rod and a cotton swab head. The cotton swab head is made of a PVA sponge and has a polyhedral structure. The polyhedral structure surface contains a large area of planar wiping surface, a small area of linear wiping hemostatic surface and a dotted wiping hemostatic point; a large area of planar wiping surface is located at the top of the cotton swab head, and a large area of planar wiping surface is inclined surface; and a small area of linear wiping surface is inclined. The hemostatic surface of swabbing is located at the top of the cotton label, and the hemostatic surface of small area linear swabbing is inclined, and the hemostatic surface of small area linear swabbing is adjacent to the large area plane swabbing; the hemostatic point of dot swabbing is located at the top of the cotton label, and the hemostatic point of dot swabbing is an end point of the intersection line of large area surface and small area linear swabbing, and removes the large area of the hemostatic surface. The other structural planes of polyhedral cotton swab head are set as stubborn bloodstain wiping planes besides small linear wiping and hemostatic planes, and the surface of stubborn bloodstain wiping surface has wavy lines that can improve friction.
【技术实现步骤摘要】
一种眼用PVA吸水止血棉签
本技术属于眼科手术器械
,特别是涉及一种眼用PVA吸水止血棉签。
技术介绍
在白内障手术中,为了保证术中视野的清晰,需要对注吸水进行引流,而目前普遍采用普通棉签进行引流,但普通棉签因受棉签头材质的限制,特别是对于眼窝深及眼球小的患者来说,注吸水的引流效果不佳,而且还会经常遗留棉絮,从而影响手术进程。在青光眼等眼科手术中会常伴出血,而出血部位需要及时进行擦拭止血,若出血部位擦拭止血处理不及时,则会影响到手术操作。而目前也普遍采用普通棉签对出血部位进行擦拭止血,但普通棉签因受棉签头形状的限制,擦拭止血效果并不理想,并且因出血部位特征的不同,普通棉签也很难做到全面适用。
技术实现思路
针对现有技术存在的问题,本技术提供一种眼用PVA吸水止血棉签,棉签头的材质为PVA海绵,其吸水能力可达普通棉签的5倍,注吸水的引流效果优良,而且不会像普通棉签那样遗留棉絮;棉签头的形状为多面体结构,并针对出血部位特征的不同设计了相对应的擦拭止血面,使本技术的眼用PVA吸水止血棉签适用性更强。为了实现上述目的,本技术采用如下技术方案:一种眼用PVA吸水止血棉签,包括棉签杆和棉签头,其特点是:所述棉签头的材质为PVA海绵,棉签头的形状为多面体结构,且在多面体的结构面中包含有大面积面状擦拭面、小面积线状擦拭止血面及点状擦拭止血尖点。所述大面积面状擦拭面位于棉签头的顶部,且大面积面状擦拭面为倾斜面。所述小面积线状擦拭止血面位于棉签头的顶部,且小面积线状擦拭止血面为倾斜面,小面积线状擦拭止血面与大面积面状擦拭面相邻。所述点状擦拭止血尖点位于棉签头的顶部,且点状擦拭止 ...
