Embodiment Construction
[0016] figure 1 It is a block diagram of the structure of the visualized minimally invasive puncture diagnosis and treatment device of the present invention. It can be seen from the figure that the puncture overtube of the device of the present invention mainly integrates a speculum and a support system, a treatment tool and a support system, and an auxiliary treatment system. However, the three systems included in the embodiment of the present invention are not limitations to the device of the present invention, and the device of the present invention can also be expanded to integrate two or more systems according to actual needs. Correspondingly, other parts The structure is also adapted to the number of systems. For example, the number of vaults.

The invention provides a visual minimally-invasive puncture diagnosis and treatment device, which comprises a puncture outer sleeve with a plurality of channels integrated inside. One end of the puncture outer sleeve is provided with a cusp portion, a taper portion of the cusp portion is provided with three holes equally, and the other end of the puncture outer sleeve is provided with an auxiliarytherapeutic tool system channel, a therapeutic tool and supporting system channel and a slight glass and supporting system channel. The cusp portion is provided with a rounded angle in a radius of 0.02mm-0.04mm, the radius of a solid in the middle of the cusp portion is smaller than 0.15mm, and the outer diameter of the puncture outer sleeve is not larger than 3.0mm while the wall thickness is 0.08-0.12mm. The visual minimally-invasive puncture diagnosis and treatment device is simple in structure, easy in operation, low in manufacturing and processing cost and extremely high in expansibility.
Description
technical field [0001] The present application relates to a medical minimally invasive device, in particular to a visualized minimally invasive puncture diagnosis and treatment device. Background technique [0002] At present, with the development of fiberoptic endoscopic technology, the surgical treatment of human intracavitary lesions has changed from traditional open surgery to endoscopic minimally invasive surgery, such as tracheal endoscopic surgery, digestive tract endoscopic surgery, urinary tract endoscopic surgery, etc. mirror surgery etc. For the puncture diagnosis, tissue sampling analysis, and resection treatment of non-luminal tissues such as liver, subcutaneous deep muscle tissue, spinal lumbar puncture, periosteal fascia, etc., often due to the single function of surgical instruments, multiple instruments such as B-ultrasound guidance or X-ray puncture or the establishment of multiple wounds can be completed, and there is no effective puncture diagnosis metho...
