Description

一种用于从人体内切割及抽吸组织的装置 技术领域
本发明涉及医疗器械领域，具体涉及一种用于从人体内切割及抽吸组织的装置。
背景技术
在医疗行业，现今的人体组织切割一般还都是采用手术刀切割手术方式来完成，但这种方式创伤面大，病人较为痛苦，且易留下伤疤等，而人体上有的器官较为精细，也不易采用手术刀切割的方式来完成。如腹腔镜下的组织切除常用微型剪刀或咬切器等，但是移除的组织量非常有限。又如用于对眼部组织的玻璃体切割，就是采用玻璃体切割器来完成对玻璃体进行切割和吸取的，由于眼睛内的玻璃体呈粘稠状，为了能实现对这种粘稠状的玻璃体、机化膜和血块等逐步搅碎移除，现有的玻璃体切割器结构都设计的较为复杂，一般为双层配合度极高的管道，工作时内管高速往复运动，这种结构的玻璃体切割器不仅体积较大，且操作不便，效率较低，难以进一步微型化、无法处理较坚硬的病变组织(如晶状体核)，在手术过程中对眼睛内的玻璃体、机化膜、晶状体及血块等进行切割和吸取效果欠佳。同时，因其液流时断时续，在引起眼内组织随之产生大幅度晃动，容易导致视网膜撕裂或误伤。
因此，如何设计一种切割创伤小、且能够缩减手术时间，减少并发症，减少病人痛苦的人体组织切割装置，是行业内有关人员亟待解决的技术问题。
发明内容
为解决上述技术问题，我们提出了一种用于从人体内切割及抽吸组织的装置，本装置可以在手术时切割及抽吸人体除骨以外的组织，如用在眼部手术时，能够较好的将玻璃体、机化膜、晶状体和血块等 人体组织及部分较脆弱的异物等逐步搅碎移除，以利于吸取并保持持续的液流，减少对其他器械的依赖，缩减手术时间，减少并发症，提高手术效果，减少病人痛苦。
为达到上述目的，本发明的技术方案如下：
一种用于从人体内切割及抽吸组织的装置，包括插入结构、震动手柄、负压装置和电控装置，所述插入结构包括均为单层管道状结构内部相通的主体部和切割部，所述切割部设于主体部的前端，所述主体部后端与所述振动手柄前端连接，所述震动手柄中部沿长度方向设有内管，内管外部设有高频振动源，且内管前端与插入结构内腔连通；所述负压装置包括负压管、真空泵和储液容器，所述内管后端与负压管一端连接，所述负压管另一端与所述真空泵连接，所述真空泵再通过管道与所述储液容器连接；所述电控装置分别通过电线与所述高频振动源、真空泵及一个脚踏开关电连接，且所述脚踏开关控制所述高频振动源和真空泵工作；
所述切割部表面上开设有至少一个吸孔，所述吸孔与插入结构内腔相通；吸孔口面上还规则设有复数条的切割丝，所述切割丝跨越在吸孔上方，其两端被固定在切割部表面上，并在高频振动源带动插入结构或前后运动，或旋转运动，或同时进行前后和旋转运动高频振动时，切割丝随其振动并增大振幅切割人体组织，在负压装置工作时整个内腔形成负压环境，人体组织一边被高频振动的切割丝进行切割，一边被吸入到吸孔内，同时切碎的人体组织被吸入插入结构内腔后，再被真空泵吸取使其沿负压管进入外部的储液容器内。
优选的，所述复数条的切割丝平行或交叉网状设置于吸孔处，且其形成的曲面形状与所述切割部外表面曲面形状基本一致。
优选的，所述复数条的切割丝为切割部表面局部管壁镂空条状缝隙后留下的部分呈网状或栅状管壁结构。
优选的，所述吸孔设于所述切割部侧面，其口面处的复数条切割丝形成的上表面弧度与切割部表面弧度相一致。
优选的，所述吸孔设于所述切割部侧面与端面连接处，其口面处 的复数条切割丝形成的上表面曲度与吸孔两侧切割部未开孔处表面曲度相一致。
优选的，所述吸孔设于所述切割部端面上，其口面处的复数条切割丝两端固定在所述切割部的侧面上或端面上。
优选的，所述高频振动源由微型高频振动电机、微型气动振动装置或超声波发生器振动源提供高频运动。
优选的，所述主体部前端为弯曲状，导致其连接的切割部弯向一侧，并在操作时切割部上的吸孔和切割丝扫过的范围能够扩大。
优选的，所述高频振动源往复或旋转的振动频率为2000-500000Hz，且能够通过电控装置根据所切割组织类型、硬度和大小，振动频率和振幅或超声能量进行调节。
通过上述技术方案，本发明通过在该装置插入结构切割部外侧面或前端面开设有至少一个吸孔，且吸孔与整个内腔相通；切割部吸孔表面还规则设有复数条的切割丝，且切割丝跨越在吸孔上方并在主体部高频振动时随其振动并增大振幅，对被负压装置吸往内腔经过吸孔吸口处的人体组织进行切割，切碎后沿内腔往外吸取，以便通过储液容器移除这部分组织；以利于吸取，提升吸取效果，减少对其他器械的依赖，缩减手术时间和更换器械次数，减少并发症，提高手术效果，减少病人痛苦，本装置可以在手术时切割及抽吸人体除骨以外的组织，达到了设计新颖、结构合理、且应用效果好的目的。
