Description

面向质量检测的无损伤止血钳钳口夹紧力的测量方法 No injury measurements hemostat jaws of the clamping force for mass detection

技术领域 FIELD

[0001] 本发明涉及医疗器械检测技术领域,特别是涉及一种面向质量检测的无损伤止血钳钳口夹紧力的测量方法。 [0001] The present invention relates to medical devices detection technology, and particularly relates to a non-invasive method of measuring the clamping force of the hemostat jaws facing a mass detection.

背景技术 Background technique

[0002] 在医院外科临床应用中,止血钳是一种常用的医疗器械。 [0002] In clinical surgery applications in hospitals, hemostat is a commonly used medical devices. 手术中,止血钳钳口从张开状态夹紧到闭合状态的过程中,两个钳口之间的夹紧力是一个从零逐渐增大的过程。 During surgery, hemostat clamp jaws from an open state to the closed state, the clamping force between the two jaws is a process gradually increases from zero. 夹紧力的大小与钳柄部的变形程度直接相关。 The magnitude of the clamping force is directly related to the degree of deformation of the clamp handle portion.

[0003] 在夹合过程前期,钳柄末端的齿扣咬合数目较少,钳柄变形程度较小,两个钳口之间的夹紧力也较小。 [0003] clamping early in the process, less number of teeth snap clamp handle engaging end, the clamp handle deformed to a lesser extent, the clamping force between the two jaws is smaller. 随着钳柄末端齿扣咬合数目的逐渐增多,两个钳柄的变形程度逐渐增大,对应的,两个钳口之间的夹紧力也逐渐增大。 As the clamp handle tip of the tooth number of snap engagement gradually increased, the degree of deformation of the two clamp handle gradually increases corresponding to the clamping force between the two jaws gradually increases. 到所有的齿扣全部咬合时,两个钳口之间的夹紧力达到最大。 When all the teeth of all the snap engagement, the clamping force between the two jaws is maximized. 医生正是利用这种对应关系,在手术中将钳柄末端的齿扣咬合数目调整到合适的程度,以在钳口处获得大小合适的夹紧力。 The doctor is the use of this relationship, the end of the tooth shank tong surgery will bite adjusted to the appropriate number of degrees, in order to obtain the clamping force of the jaws at the right size. 钳口夹紧力大小是否合适严重影响着手术质量。 Whether or not the right size jaw clamping force a serious impact on the quality of surgery. 若夹紧力太小,则钳口对血管起不到足够的夹紧作用,会导致一定程度的渗血。 If the clamping force is too small, it will not achieve a sufficient vascular jaw clamping action will cause a degree of bleeding. 若夹紧力太大,则钳口将夹伤血管甚或导致血管的碎裂,给手术带来麻烦并给患者造成不必要的伤害。 If the clamping force is too large, the jaws will crush the vessel or even lead to broken blood vessels, surgery to cause trouble and cause unnecessary harm to patients.

[0004] 当前,不同厂商生产的同一型号止血钳在材料和规格方面都有所差别,这导致即使在钳柄末端咬合相同数目的齿扣,钳口处的夹紧力也不尽相同,而这种差别将直接影响到止血钳的临床使用效果。 [0004] Currently, different manufacturers of the same model hemostat materials and specifications that are different, which results in the shank end of the jaw bite even the same number of teeth buckle, the clamping force of the jaws are not the same, and this species differences will directly affect the clinical use of hemostats effect. 为了便于生产厂商对现有成熟型号的止血钳或处于改进试制阶段的止血钳进行准确的钳口夹紧力测定,以进行质量认定,需要确定一种精确合理的止血钳钳口夹紧力测量方法。 For convenience of the manufacturer or a hemostat at the trial stage of the improved hemostatic clip of the type of existing mature accurate measurement jaw clamping force, for the quality of that, it is necessary to identify a reasonably accurate measurement of the clamping force hemostat jaws method.

[0005] 经对现有技术的文献检索发现,专利号为ZL200820016910. 9的中国实用新型专利《止血钳》(公告号为CN201139601Y)公开了一种新型止血钳。 [0005] Document Retrieval been found that the prior art, Patent No. ZL200820016910. 9 in Chinese utility model patent "hemostats" (Publication No. is CN201139601Y) discloses a novel hemostatic clip. 该专利通过将两个钳臂的前端与钳口内侧平面的连接处设计为原弧面,解决了常规止血钳钳口根部在手术中容易损伤软组织的缺陷。 The design of the connector at the front end of the jaw of the inner pliers limb two original planar arc to solve the drawbacks of conventional surgical hemostat jaws root easily damaged by the soft tissue of the patent. 但是,该专利对止血钳的改进仅限于钳口局部的形状设计,并不能实现对钳口夹紧力的精确测量。 However, this patent hemostat jaws is limited to the improvement of local shape design, and can not achieve accurate measurement of the clamping force of the jaws. 申请号为200710185338. 9的中国发明专利《焦炉捣固机锤杆夹紧力的测量调整方法及测量系统》(公告号为CN101206151A)公开了一种焦炉捣固机锤杆夹紧力的测量调整方法。 Application No. 200710185338.9 the Chinese invention patent "coke tamping machine hammer rod clamping force measuring system measuring and adjusting method" (published No. CN101206151A) discloses a coke oven tamping machine clamping force of the hammer measurement adjustment method. 该专利涉及夹紧力测量,但其应用与医疗器械检测分属不同的领域, 待检测部位和检测条件也与止血钳钳口夹紧力测量相差甚远。 This patent relates to a clamping force measurement, but its application to the medical instrument detected belong to different areas, portions to be detected and the detection conditions clamping force measuring far hemostat jaws. 到目前为止,尚无专门用于止血钳钳口夹紧力测量的方法。 So far, no specific method for the hemostat jaws clamping force measurements.
