Description
技术领域technical field
本发明涉及一种过滤装置，尤其是一种便于手术标本收集装置。The invention relates to a filtering device, in particular to a device for collecting surgical specimens.
背景技术Background technique
微创手术是现代外科医学的发展方向，包括各种内镜手术及显微手术，它以切口小、创伤轻为特征。手术中必须使用吸引器(特别是超声吸引器)，肿瘤等组织标本被吸引器吸走，造成肿瘤等组织标本大部丢失。特别是颅内肿瘤体积相对较小，标本大部丢失后造成病理诊断困难；同时微创手术切口小，难以看到病变全部，标本大部丢失后难以估计手术中病变切除程度。为获取上述肿瘤等组织标本，现在一般都是采用取瘤钳进行肿瘤等组织标本的夹取，但微创手术只能容下纤细的器械，所夹取组织也较小且费时费力；特别深部手术用取瘤钳更显笨拙，不仅影响手术视野，且取标本时易引起出血。如果能保留吸引器吸出的标本，不仅可满足病理诊断需要，还可估计手术中病变切除程度；更重要的是可以使手术操作简单化，缩短手术时间、减少术中出血，造福广大患者。Minimally invasive surgery is the development direction of modern surgical medicine, including various endoscopic surgery and microsurgery, which is characterized by small incision and light trauma. Aspirators (especially ultrasonic aspirators) must be used during the operation, and tissue samples such as tumors are sucked away by the aspirator, causing most of the tissue samples such as tumors to be lost. In particular, the volume of intracranial tumors is relatively small, and most of the specimens are lost, making pathological diagnosis difficult. At the same time, minimally invasive surgery has small incisions, making it difficult to see all the lesions, and it is difficult to estimate the extent of lesion resection during surgery after most of the specimens are lost. In order to obtain the above-mentioned tumor and other tissue samples, tumor forceps are generally used to capture tumor and other tissue samples, but minimally invasive surgery can only accommodate slender instruments, and the clamped tissues are small and time-consuming; especially deep Surgical tumor-taking forceps are more clumsy, which not only affects the surgical field of view, but also easily causes bleeding when taking specimens. If the aspirated specimens can be retained, it can not only meet the needs of pathological diagnosis, but also estimate the degree of lesion resection during operation; more importantly, it can simplify the operation, shorten the operation time, reduce intraoperative bleeding, and benefit the majority of patients.
中国实用新型专利CN 203710053 U公开了一种手术标本收集器，该手术标本收集器包括收集瓶，收集瓶上盖有密封盖密封盖上设有吸入接口、出气接口，收集瓶下端设有排水接口，密封盖下设有一连接杆，连接杆与一过滤网连接，过滤网位于收集瓶内，过滤网上端部分的收集瓶截面积大于或等于过滤网下端部分的收集瓶截面积；该标本收集器通过连接杆与过滤网连接，从而利用连接杆把过滤网从收集瓶中取出，容易导致标本及组织液掉落到收集瓶外，容易造成疾病传播，从而影响工作环境。Chinese utility model patent CN 203710053 U discloses a surgical specimen collector, the surgical specimen collector includes a collection bottle, the collection bottle is covered with a sealing cover, the sealing cover is provided with a suction port and an air outlet port, and the lower end of the collection bottle is provided with a drainage port , a connecting rod is arranged under the sealing cover, the connecting rod is connected with a filter screen, the filter screen is located in the collection bottle, and the cross-sectional area of the collection bottle at the upper part of the filter screen is greater than or equal to the cross-sectional area of the collection bottle at the lower part of the filter screen; the specimen collector The connecting rod is connected to the filter screen, so that the filter screen is taken out from the collection bottle by the connecting rod, which may easily cause the specimen and interstitial fluid to fall out of the collection bottle, easily cause disease transmission, and thus affect the working environment.
