When the movable sampling knife clack is closed, the movable sampling knife clack forms a tapered shape, and the utility model is in favor of being inserted in a body. The utility model can opened in the living tissue, and can be used for observing and exactly choosing a sampling point; the movable sampling knife clack is closed to cut living tissues; the living tissues sampled are packed in the movable sampling knife clack, and then living tissues sampling is finished. The utility model is used for sampling the living tissues has the advantages of time saving, labour saving and little pain on a patient.

Description

一种体内活组织取样器 An in vivo biopsy sampler

所属技术领域 Those of skill

:本实用新型涉及的是一种医疗诊断上用于活组织检查的取样装置,尤其是一种体内活组织取样器。 : The present invention relates to a biopsy sampling device for a medical diagnosis, in particular, a living body tissue sampler.

本方案是通过如下技术措施来实现的:主要包括带有窥镜视物头、窥镜光导纤维和窥镜目视头的窥镜,本方案的特点是在所述的窥镜视物头和部分窥镜光导纤维的外面固定有内套管,在内套管的外面有可沿轴线相对内套管微量移动的外套管,在外套管的前端有三至四瓣活动取样刀瓣,该活动取样刀瓣与外套管之间有铰链连接,活动取样刀瓣的末端与内套管之间有支点活动连接。 This solution is achieved by the following technical measures: including with a head, the optical fiber endoscope, and the endoscope head in the endoscope visual, depending on the material characteristics of the endoscope of the present embodiment is the head of the endoscope and the visual the outer part of the optical fiber of the endoscope within the sleeve is fixed outside the inner sleeve relative to the outer sleeve inner sleeve may be moved along the axis trace, the distal end of the outer sleeve has three to four sampling events blade flap, the event sample a hinged flap between the knife and the jacket pipe has a fulcrum connection between the sleeve and the inner end flap active sampling tool. 本方案的具体特点还有,在所述的每个活动取样刀瓣的两侧边有刃口。 Specific features of the program also has side edges on each active edge sampling tool according flap. 在所述的内套管和外套管之间有限位器。 Between said inner and outer sleeves is limited spaces.

本方案的有益效果可根据对上述方案的叙述得知,由于该方案中,在窥镜的窥镜视物头和部分窥镜光导纤维的外面固定有内套管,在内套管的外面有外套管,并由两套管间的限位器控制内、外套管之间的相对微量移动,在外套管的前端有三至四瓣两侧边有刃口的活动取样刀瓣,该活动取样刀瓣与外套管之间有铰链连接,与内套管之间有支点活动连接。 Advantageous effects of the present embodiment may be described according to the above scheme that, since this embodiment, the outside of the endoscope and the endoscope visual header portion of the optical fiber is fixed to the endoscope inner tube, the inner tube has outer the outer sleeve, by the stop control between the ferrules, the relative movement between the micro overtube distal end of the outer sleeve has three to four side edges with active sampling knife edge of the flap, the event sampling knife hinge connection between the flap and the outer sleeve, the pivot connection between the active and the inner sleeve. 这一结构,活动取样刀瓣可在内、外套管的相对移动下张开或闭合,当活动取样刀瓣闭合时,活动取样刀瓣呈锥状,有利于插入体内,当活动取样刀瓣插入到体内后,在病灶处张开活动取样刀瓣,用窥镜就可观察到需要取样的部位,选准取样点,闭合活动取样刀瓣切除活组织,将取样到的活组织包在活动取样刀瓣内,拔出取样器,就可获得需要取样的活组织。 This structure may be active sampling tool including valve, open or closed relative movement of the outer sleeve, when the movable blade sampling valve is closed, the movable blade flap sampling tapered, to facilitate insertion body, the insertion flap when the movable blade sampling after the body, opening the lesion activities sampling knife valve, can be observed with the endoscope to the site of sampling is required, selecting the right sampling points, sampling tool flap for closing activity of living tissue, the living tissue sampled into the sampling event package knife inside flap, pull out the sampler, you can get the biopsy sampling is required. 用此方法进行的活组织取样,可省时、省力,并对病人造成的痛苦也小。 Biopsies performed with this sampling method, can save time, effort, and caused the suffering of patients is small. 由此可见,本实用新型与现有技术相比,具有实质性特点和进步,其实施的有益效果也是显而易见的。 Thus, the present invention over the prior art, has substantive features and progress in the implementation of its beneficial effect is obvious.

图中1为活动取样刀瓣,2为窥镜视物头,3为内套管,4为外套管,5为窥镜目视头,6为窥镜光导纤维,7为限位器。 Figure 1 is a flap active sampling tool, the endoscope visual head 2, the inner sleeve 3, the outer sleeve 4, 5 of the endoscope visual head, an optical fiber endoscope 6, 7 stop.
