Suture-tying forceps have been designed to enable surgeons to tie consecutive sutures to the same tension to create an evenly compressed wound. The tensioning effect of the forceps was tested by tying a suture to the end of a cantilever beam strain-gauge device. Three sutures were used: 10/0 nylon, 8/0 polyglactin (Vicryl) and 8/0 virgin silk. The tests were repeated, coating the tips with citrated blood, sodium hyaluronate and saline. Adjustment of the forceps altered the suture tension in 0.015-N steps. Sterilization of the forceps by ethylene oxide or by an autoclave caused no obvious regression in the forceps performance. When the suture and surface lubricant remain constant, there is a linear relationship between forceps setting and the tension induced in the suture.
缝扎钳的设计目的是使外科医生能够将连续的缝线打结至相同的张力，以形成均匀受压的伤口。通过将缝线系在悬臂梁应变计装置的末端来测试钳子的张紧效果。使用了三种缝线：10/0尼龙线、8/0聚乙醇酸（薇乔）线和8/0天然丝线。重复进行测试，在钳尖涂上枸橼酸化血液、透明质酸钠和生理盐水。钳子的调节以0.015牛的步长改变缝线张力。通过环氧乙烷或高压灭菌器对钳子进行灭菌，钳子的性能没有明显下降。当缝线和表面润滑剂保持恒定时，钳子的设置与缝线中产生的张力之间存在线性关系。
