Description

一种用于真空辅助乳腺旋切系统的穿刺旋切针测试方法A test method for puncture rotary cutting needle used in vacuum assisted breast rotary cutting system

技术领域technical field

本发明涉及微创旋切教学技术领域，尤其涉及一种用于真空辅助乳腺旋切系统的穿刺旋切针模拟测试方法。The invention relates to the technical field of minimally invasive rotary excision teaching, in particular to a simulation test method for a puncture rotary excision needle used in a vacuum-assisted rotary mammary gland excision system.

背景技术Background technique

外科手术的迅疾发展，以精准切除以获取最大健康保障的观念日渐成为外科发展方向，对美观的追求，使微创外科在保证了安全可靠的前提下更易于为人们接受和认可。微创旋切系统应运而生，它由活检诊断发展而来，检诊断在早期多用于传染性疾病的确诊，1971年以FNA用于可触及的乳腺肿物的活检诊断，之后用于在X 线的引导下以穿刺诊断不可触及乳腺病变 。FNA因取材量少、或需重复穿刺等缺点而不能满足活检需求。1990 年，Parker 等首次描述CNB，因设备简单、操作方便、对乳腺明显包块取材准确且组织充足，以较高的敏感度、特异度和准确性，而被作为诊断乳腺癌的主要方法之一，广泛应用于临床。综上，细针抽吸活检的标本量少，诊断可靠性差，而粗针穿刺活检标本量较大，病理诊断准确率较高，但是冰冻病理检查可靠性差。VAB是CNB的粗针变异体。Burbank在空芯针穿刺活检技术基础上于1994年成功研制出微创旋切活检系统麦默通。2004年美国FDA正式批准其用于乳腺病灶的活检诊断,后逐渐应用于乳腺肿物的治疗。该设备对乳腺可疑病灶可进行重复切割，以获取乳腺的组织学标本，为乳腺癌发现和诊断提供更好的方法，同时为良性肿瘤的为创切除提供技术基础。With the rapid development of surgery, the concept of precise resection to obtain maximum health protection has gradually become the direction of surgical development. The pursuit of aesthetics has made minimally invasive surgery more acceptable and recognized by people on the premise of ensuring safety and reliability. The minimally invasive rotary cutting system came into being. It was developed from biopsy diagnosis, which was mostly used for the diagnosis of infectious diseases in the early stage. In 1971, FNA was used for biopsy diagnosis of palpable breast tumors, and later used in X Diagnosis of non-palpable breast lesions by puncture under the guidance of thread. FNA cannot meet the needs of biopsy due to the small amount of material taken, or the need for repeated punctures. In 1990, Parker et al. described CNB for the first time, and it was used as one of the main methods for diagnosing breast cancer because of its simple equipment, convenient operation, accurate and sufficient tissue for obvious breast masses, and high sensitivity, specificity, and accuracy. First, it is widely used in clinical practice. In conclusion, fine-needle aspiration biopsy has a small sample volume and poor diagnostic reliability, while coarse-needle aspiration biopsy has a large sample volume and high pathological diagnosis accuracy, but the reliability of frozen pathological examination is poor. VAB is a thick needle variant of CNB. Burbank successfully developed the minimally invasive rotary biopsy system Mammotome in 1994 based on core needle biopsy technology. In 2004, the US FDA officially approved it for biopsy diagnosis of breast lesions, and then it was gradually applied to the treatment of breast tumors. The equipment can repeatedly cut suspicious breast lesions to obtain breast histological specimens, provide a better method for breast cancer discovery and diagnosis, and provide a technical basis for invasive resection of benign tumors.

然而在现有的乳腺穿刺旋切手术中，大都均采用标准型号的穿刺旋切针头，或者根据患者年龄段选择不同型号的穿刺旋切针头，由于每位患者的皮肤组织都不相同，导致每位患者对于穿刺旋切针头的受用度也不相同，如果使用了细型号的穿刺旋切针头可能会出现获取的组织量较少，无法明确病变的性质，无法制成病理切片的问题，如果使用了粗型号的穿刺旋切针头可能会伤害到穿刺部位的神经、血管、出现损伤风险更大，所以模拟测试穿刺旋切针头找到对患者最适用的穿刺旋切针型号是至关重要的。However, most of the existing rotary mammary gland aspiration and aspiration operations use a standard type of puncture rotary ablation needle, or select a different type of puncture rotary ablation needle according to the patient's age group. Since each patient's skin tissue is different, each Different patients have different acceptance of the puncture rotary cutting needle. If a thin type of puncture rotary cutting needle is used, the amount of tissue obtained may be less, the nature of the lesion cannot be clearly defined, and pathological sections cannot be made. The thicker puncture rotary cutting needle may injure the nerves and blood vessels at the puncture site, and the risk of injury is greater, so it is very important to simulate and test the puncture rotary cutting needle to find the most suitable puncture rotary cutting needle model for the patient.
