Most practitioners in plastic surgery believe that blunt tipped cannulae are safer. Interestingly, there is no study about their safety, and the problem is exactly this. As the use of blunt tipped cannulae is somehow difficult, some surgeons try other extreme alternatives, such as sharp and cutting tipped injection needles. But, they can cause complications such as vessel damage. According to these hypotheses, we tried to design a cannula which would ease the application of lipofilling and which would minimise the trauma. Contrary to the injection needle, the tips of the cannula would be blunter, and trauma would be diminished.
After designing such a cannula, we compared it with the most frequently used Coleman type cannulae with regard to ease in utilisation, and safety. We also tried to evaluate the potential for trauma, of the regularly used cannulae.
In the first part, the penetration capacity of all cannulae was measured and compared, and in the second part, the tissue damage was evaluated in an experimental model.
According to the statistical and histological findings, the pointed-tip cannulae, blunted to a certain degree, can be applied easily through the tissues. The surgeon works more comfortably and we have noted that these cannulae cause less tissue damage.
大多数整形外科医生认为钝头套管更安全。有趣的是，目前尚无关于其安全性的研究，而问题恰恰在此。由于使用钝头套管存在一定难度，一些外科医生尝试其他极端替代方法，比如尖头和带切割头的注射针。但是，它们可能会引发诸如血管损伤等并发症。基于这些假设，我们试图设计一种套管，既能便于脂肪填充操作，又能将创伤降至最低。与注射针不同，套管的尖端将更钝，创伤也会减小。
设计出这样一种套管后，我们将其与最常用的科尔曼型套管在使用便利性和安全性方面进行了比较。我们还试图评估常用套管造成创伤的可能性。
第一部分，测量并比较所有套管的穿透能力，第二部分，在实验模型中评估组织损伤情况。
根据统计和组织学结果，尖端钝至一定程度的套管能够轻松穿透组织。外科医生操作起来更舒适，并且我们注意到这些套管对组织造成的损伤更小。
