The utility model relates to an intra-tissue channel generator, which belongs to a medical device for forming a subcutaneous channel. The utility model comprises a handheld part and a clamping part composed of two cross clamping rods connected by a rotating shaft. The features are as follows: the front end of the clamping rod is provided with a channel forming rod perpendicular to the plane where the clamping part is located, and the two channel forming rods are parallel to each other; and the inner side of the handheld part is provided with a locking member. The utility model has the advantages of simple structure and strong practicability. The main application of the utility model is that the stripping range is precise when it needs to form an intra-organizational channel, and the distal and proximal channels are of the same size. It can form an intra-organizational channel at one time and reduce the damage caused by multiple channel expansion. The device can clamp the tissue passing through the channel and smoothly pass through the channel, thus alleviating the work difficulty of medical personnel. It can reduce tissue damage and bleeding, shorten operation time and reduce operation risk, and is conducive to high-quality and fast operation.

组织内通道形成器
本技术属于一种形成皮下通道的医疗器械,具体涉及一种通道形成器。
技术介绍
组织内通道形成器,是骨科、整形科、创伤修复科、脑外科等临床医师需要在组织内形成通道时常用的一种医疗器械,主要应用在带皮肤的血管皮瓣翻转植皮或带肌肉的血管皮瓣植皮等覆盖患者缺损组织时,需要将翻转的血管皮瓣等组织穿过皮下通道再覆盖到需要植皮、组织覆盖的组织缺损部位。在传统的手术中,医师没有专用的组织内通道形成器,常常用骨膜剥离器、血管钳、组织钳等器械代替皮下通道形成器。但用上述器械代替通道形成器常见有以下缺点:(1)通道形成长短、宽窄不合适,比如用血管钳代替组织内通道形成器时,由于血管钳前端较短,不能达到通道需要的长度,且血管钳前端钳体张开时为前大后小结构,形成的通道大小不一,在操作时,为了达到远端通道的形成,常常将通道近端过分扩大,造成了人为的组织损伤、出血;比如用骨膜剥离器代替组织内通道形成器时,由于骨膜剥离器宽度有限,一般为5mm-15mm宽,当我们需要较大的组织内通道时,常常达不到通道大小、宽窄的要求,有时为了达到所需要的宽度,操作者常用暴力左右移动骨膜剥离器,由于力度 ...
