摘要： Disclosed are a polydopamine film and a preparation method and application thereof. The polydopamine film is loaded with silver sulfadiazine, and the preparation method achieves in-situ synthesis of silver sulfadiazine on a conventional polydopamine film by microwave irradiation. In the method, the sulfadiazine is not dissolved in conventional aqueous ammonia, which has the following advantages: firstly, preventing the polydopamine film from being corroded by the aqueous ammonia; secondly, protecting mucosa such as eyes and nasal cavities of workers from stimulation and corrosion of the aqueous ammonia; and thirdly, avoiding the environmental problem caused by pungent odor and fumes emitted from high-concentration aqueous ammonia. In the method, without using the catalyst of trifluoromethanesulfonic acid or trifluoromethanesulfonic salt, not only is the loading of silver sulfadiazine increased, but also the safety performance can be further improved.

摘要： A surgical stapler and a control method therefor. A control part of the surgical stapler is used to acquire a real-time drive current value and a jump current average value of a drive part; then, determine the difference value between the drive current value at a current moment and the drive current value at a previous moment; compare the difference value to the jump current average value, if the difference value is greater than the jump current average value, control the drive part to stop working. Thus, an operator does not have to determine by his or herself whether anastomosis action is completed before operating the surgical stapler, thereby increasing surgical efficiency.

摘要： The present invention discloses a preparation method of a titanium nail capable of loading a drug. The titanium nail capable of loading a drug includes a titanium nail body capable of loading a drug, and a microporous ceramic layer capable of loading a drug arranged on the surface of the titanium nail body. The steps of the method include: pretreating the surface of the titanium nail body, preparing a microporous mould for hyaluronic acid-alginic acid microspheres, preparing a titanium sol solution, coating film, pore-forming and roasting. The present invention also discloses a titanium nail capable of loading a drug obtained by the preparation method above, and a drug-loaded titanium nail prepared with the titanium nail capable of loading a drug and a preparation method thereof. With the microporous ceramic layer on the surface of the titanium nail body, it is hard for the metal ions on the surface of the titanium nail to penetrate the human body, due to the properties of corrosion resistance and wear resistance of the ceramics. Further, it fails to generate the exfoliations and the wear debris to prevent the human body from "wear debris disease" and reaction to a foreign body. Moreover, various drugs such as the antibacterial drugs, and the drugs for promoting the healing etc. can be loaded, targeted and slow-released, which is good for medical usage.
摘要翻译：本发明公开了一种能够装载药物的钛钉的制备方法。能够装载药物的钛钉包括能够装载药物的钛钉体和能够装载排列在钛钉体表面上的药物的微孔陶瓷层。该方法的步骤包括：预处理钛钉体表面，制备透明质酸 - 海藻酸微球微孔模具，制备钛溶胶溶液，涂膜，成孔和焙烧。本发明还公开了一种能够装载通过上述制备方法得到的药物的钛钉和一种能够装载药物的钛钉制备的载药钛钉及其制备方法。由于陶瓷的耐腐蚀性和耐磨性，钛钉体表面的微孔陶瓷层难以渗入钛钉表面的金属离子。此外，它不会产生剥落和磨损碎片，以防止人体“磨损病”和对异物的反应。此外，可以装载各种药物如抗菌药物和促进愈合的药物，作为目标和缓释，这对医疗用途是有益的。

摘要： A cutting control method, device and storage medium applied to an ultrasonic knife. The method comprises: detecting a present active power of the ultrasonic knife (S101); and when the present active power is greater than a predetermined power critical value, and in the case that a duration of the present active power greater than the power critical value reaches a first predetermined time, a rated operating current of the ultrasonic knife is gradually lowered in a stepwise manner according to a predetermined time interval (S102). The control method and device accurately identify whether the ultrasonic knife enters the cutting end by detecting the active power of the ultrasonic knife, so that the operating current of the ultrasonic knife can be adjusted in time to lower the energy output of the ultrasonic knife when it enters the cutting end, that is, the cutting tissue becomes less, so as to effectively prevent the thermal damage of the tissue.

摘要： Disclosed are a bendable endoscopic linear cutting anastomat and assembly thereof, comprising an anastomat jaw, a turning connection block, an assembly inner core and a cutting blade assembly; the assembly inner core comprises an inner core shell and an inner core connection block fixedly mounted in the inner core shell; the front end of the turning connection block is hinged to the rear end of the anastomat jaw, a first vertical rotation shaft is formed at the hinge, the rear end of the turning connection block is hinged to the front end of the inner core connection block, a second vertical rotation shaft is formed at the hinge; the cutting blade assembly penetrates through the inner core connection block, the turning connection block and the anastomat jaw, and can slide forwards and backwards. On the basis of the above-mentioned dual rotation shafts (centers), the present invention also adopts a U-shaped left and right bending sheet which controls the bending process by the turning of the inner core connection block. By means of the above-mentioned arrangement in the present invention, the bending radius can be increased, thereby reducing the firing force during cutting and anastomosing, and enabling a doctor to have a better operation hand feeling. In addition, a larger bending angle can be achieved, so that the doctor has a better operation space.

摘要： Disclosed are an anastomat and a timed discharging method thereof, belonging to the technical field of medical devices. The anastomat includes a body tail plate and a battery pack, a triode and a controller. The elastic sheets for positive and negative signals of the body tail plate are connected to the upper and lower signal conducting sheets in the battery pack by means of a mechanical mechanism, and afterwards are used for outputting a signal for the anastomat. After the power clamping reed of the body tail plate is connected to the power output conducting plate in the battery pack by means of a mechanical structure, the power clamping reed is used for outputting power for the anastomat. The controller is used for controlling the operation of a battery panel in the battery pack, wherein the base of the triode is connected to a pin corresponding to the controller, the collector of the triode is connected to the battery panel, and the emitter of the triode is grounded. The discharging method is implemented based on the anastomat. In the case where it is ensured that electric power can be outputted sufficiently when the battery pack is used, the risk issue of the remaining electric power after the battery is used is solved.
