The present invention provides devices, systems and methods for tissue access and repair at a treatment site. The devices, systems and methods of the present invention will be suitable for use in a variety of therapeutic procedures including endovascular, minimally invasive and open surgical procedures, and may Used in various anatomical regions of bladder, lungs and other organs, blood vessels and tissues. The present invention is particularly useful for those procedures requiring minimally invasive or intravascular access to distal tissue sites, where the instruments utilized must travel along long, narrow and tortuous paths to reach the treatment site. Additionally, many of the devices and systems of the present invention can be reversible and removed from the patient at any point without interfering with or damaging the internal tissue.

A combined abdominal aorta covered stent system and a utilization method thereof are applied to surgeries for endovascular interventional treatment of abdominal aortic aneurysm. The system comprises a body covered stent and a pair of branch covered stents, and each of the stent is cylindrical and provided with a delivery system. The near end of the body covered stent is a bare stent with barbs, a covered section comprises an upper half portion in a single-cavity cylinder shape and a lower half portion with a fixed outer diameter, and the lower half portion is averagely partitioned into two cavities by a longitudinal partition. Small-waveband stent rings are designed at near and far ends of the covered section of the body covered stent, and other covered parts can be either provided with stent rings or not. The upper half portion of the covered section is implanted at a neck position of infrarenal aortic aneurysm, and the lower half portion is suspended in an aneurysm cavity. The branch covered stents parallelly and internally sleeve the two cavities of the body covered stent, near ends of the branch covered stents are flush with the near end of the lower half portion of the body covered stent and fill the cavities of the body covered stent in a self-adoption manner, and far ends of the branch covered stents are implanted into iliac artery branches to better adapt to arterial aneurysms excessive in aneurysm neck torsion.

The invention relates to a tumor microwave assisted nursing instrument, and belongs to the technical field of a medical apparatus. The tumor microwave assisted nursing instrument comprises an equipment moving base plate, and is characterized in that the lower side of the equipment moving base plate is provided with pulley fixing legs, the lower side of each pulley fixing leg is provided with a moving pulley, a nursing instrument storage frame is arranged at the upper side of the equipment moving base plate, a circuit sorting box is arranged at the left side of the nursing instrument storage frame, a power supply wire output opening is formed in the left side of the circuit sorting box, a power supply conducting wire is arranged at the left side of the power supply wire output opening, a power supply plug is arranged on the power supply conducting wire, an equipment storage box is arranged at the lower side of the nursing instrument storage frame, and an opening rotating door is arranged at the front side of the equipment storage box. The tumor microwave assisted nursing instrument has the advantages that the structure is simple, the operation is simple and convenient, the tumor microwave assisted nursing instrument can help patients to realize nursing before and after tumor treatment surgeries, the pain of the patients is reduced, the rehabilitation efficiency is improved, and the workload of medical staff is lightened.

The invention discloses a method for preparing a composite membrane for treating leucoderma from autologous follicle melanocytes. Enough autologous melanocytes are separated from follicles of a patient; cells are transferred to a biological membrane to continually grow by using the characteristics that performances and functions of the autologous melanocytes changed after the autologous melanocytes are cultured and amplified, so that the controllability of the cells is effectively improved and clinicians can extremely conveniently use the composite membrane. The defects of a traditional leucoderma treatment surgery that the damages are great, the treatment time is long, the treated skin lesion face is not large, the surgery is not suitable for treating infants and children, and scars are formed and the like are avoided. The method is convenient to operate, has good repeatability and is suitable for large-scale popularization of clinic treatment of the leucoderma.

The invention discloses a disposable lesser lip plastic surgery designer, which comprises two connecting strips hinged into an opening and closing structure, wherein the two connecting strips are provided with cuttable reference sheets at one end respectively; and when the two connecting strips are closed, the two reference sheets are overlapped completely. When the designer is applied to a plastic surgery for asymmetrical lesser lips on both sides, the two reference sheets are used for clamping a smaller side lesser lip and are cut to the same shape as the smaller side lesser lip, the two cut reference sheets are used for clamping the lesser lip on a side which is required to be cut, and line drawing or cutting is performed by taking the overlapped reference sheets as a reference template. The designer is convenient to operate, and the surgery accuracy and surgery efficiency can be increased effectively. Meanwhile, a postoperative shape can be designed on the reference sheets in advance when the designer is applied to treatment surgery on hypertrophy of lesser lips on both sides, so that the mentioned effect can be achieved.
