Technical Field

the invention relates to the field of medical instruments, in particular to a neuroendoscope with a suction device and a using method thereof.

Background

The neuroendoscopy is a main instrument for developing the neurosurgery endoscopic surgery, and along with the development of the surgical technology, the neuroendoscopy has wide application in the aspects of cerebrovascular diseases, craniocerebral tumors, craniocerebral fundus surgery and the like, and compared with the traditional surgery mode, the neuroendoscopy has the advantages of small trauma, clear visual field and the like when being operated, and can partially replace the traditional surgery mode in the treatment of certain craniocerebral diseases, thereby obtaining more satisfactory curative effect. In the process of using the neuroendoscope to perform surgery, other instruments are often needed to cooperate, and among them, an aspirator is one of the most commonly used instruments. The aspirator can be with blood, tissue fragment etc. the clean of gettering in the art field, guarantees that the neural scope operation field of vision is clear, is the prerequisite and the assurance that carry out the operation under the neural scope safely, accurately.

Traditional neural scope and aspirator are independent each other, and during the operation, the operator holds the neural scope in one hand, and the aspirator is held to the other hand and is attracted, treats that the art field is clear after, takes out the aspirator from the art field, trades other surgical instruments again and operates. This approach has the following problems: 1. because the hand for carrying the neuroendoscopy is relatively fixed, the other hand is required to be frequently replaced between the suction apparatus and other surgical instruments, and the continuity and the efficiency of the surgical operation are influenced; 2. under the condition that the art field bleeding speed is faster, need carry out the aspirator and continue to attract keeping the art field clear condition at the art person and carry out subsequent operations such as stanch, but the art person can't reuse third kind surgical instruments simultaneously this moment, must rely on assistant to assist and attract or stanch the operation, because neuroendoscopy operation itself is minimal access surgery, and the art field is narrow and small, and many people operate mutual interference can influence the operation effect on the contrary, causes the tissue damage even.
