When the blocking forceps manufactured by the forceps end mechanism in the invention are utilized to perform celioscope partial nephrectomy and the like, the renal artery is effectively blocked, therefore, an operation is performed in a bloodless state; and meanwhile, renal artery puncture and low temperature perfusion can be performed, thereby protecting kidney functions to the maximum degree. The mechanism has the advantages of reasonable design, simple structure, high success rate, convenient of use and the like.

Navigation system for intramedullary reduction of diaphysis fractures
InactiveCN106859766BReset status is clearly observedGet rid of over-reliance on experienceSurgical navigation systemsX-rayNavigation system
In order to solve above technical problems, the invention provides a navigation system used for shaft fracture intramedullary reduction. The system comprises a marrow cavity endoscope, an image display module, a computer, an electromechanical control module, and a mechanical traction frame. The image display module is electrically connected between the marrow cavity endoscope and the computer. The electromechanical control module is electrically connected between the mechanical traction frame and the computer. The marrow cavity endoscope acquires image signals of proper positions, and transmits the image data to the computer through the image display module. After the image data is displayed, analyzed and processed on the computer, a displacement instruction is transmitted to the electromechanical control module. The electromechanical control module drives the mechanical traction frame to complete corresponding displacement operation. The system is characterized in that operation is simple, axial alignment and rotation alignment are realized, X-ray radiation damages are prevented, the system monitors reduction state in real time, and is high in precision, and can maintain a satisfied closed reduction state for a long time.
