Description

Novel hard bronchoscope seal assembly Technical Field The utility model relates to the technical field of medical equipment, in particular to a novel hard bronchoscope sealing component. Background The hard bronchoscope is an instrument widely applied to diagnosis and treatment of respiratory diseases, has the advantages of high operation precision, capability of applying larger force, capability of passing larger operation channel and the like, is suitable for complex airway intervention operation, such as removal of airway foreign matters, tumor excision, stent placement, expansion treatment of airway stenosis and the like, has more outstanding importance when the operation in the airway is involved, and is suitable for clinical application of the hard bronchoscope, the tightness and ventilation management of the airway are one of the key problems, a hard bronchoscope is provided with a central working channel, a breathing machine access channel, a light source access channel and a carbon dioxide monitoring channel, the hard bronchoscope is usually used for temporarily sealing the opening of the bronchoscope during operation, the problems of maintaining airway pressure and ventilation in the operation process are successfully solved, the airtight ventilation of four channels is very important in the operation process of the hard bronchoscope, and the problem of opening and closing the channels can cause hypoxia, so that the sealing component of the hard bronchoscope is particularly important. The traditional Korotkoff cap is internally provided with a screw, the Korotkoff cap is plugged into the duct when in use, the inner diameter of the duct is reduced, the operation range is reduced, particularly when a plurality of medical instruments (such as a grasper, an aspirator and the like) are needed to be used simultaneously in the central working duct, the operation is difficult due to the insufficient space, when the fiber bronchoscope and other instruments (such as the grasper) are used for combined operation, the fiber bronchoscope and the other instruments are wound in the central working duct, the winding not only affects the operation flexibility of the instruments, but also can increase the operation time and even cause equipment damage, the situation is not rare in actual operation, in actual clinical operation, in order to avoid the problems, when the fiber bronchoscope is used for combined operation of the grasper, the rubber glove is used for temporarily replacing a carbon dioxide monitoring duct plug, the fiber bronchoscope is monitored by carbon dioxide monitoring duct, the operation space is increased, but the rubber glove is not ideal for sealing the sealing of the fiber bronchoscope, the carbon dioxide monitoring duct is required to be blocked, the operation is complicated, meanwhile, the traditional sealing film is usually only used, the sealing film passes through the sealing film on the medical instrument and enters the hard bronchoscope, and the hard instrument passes through the hard bronchoscope to enter the hard instrument to the hard mask, and is required to be stably carried out in the hard-sealed bronchoscope, and the hard instrument is required to be stably and stably carried out in the medical device is required to be in the hard-sealed and is required to be stably-backed-back to the medical device, and the hard bronchoscope is required to be stably-backed to be stably and stably-carried forward in the medical device. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides a novel hard bronchoscope sealing component which is used for solving the problem of increasing the operation space as much as possible under the condition of ensuring the tightness and the problem of backtracking of medical instruments. In order to solve the problems, the technical scheme is that the novel hard bronchoscope sealing component comprises a central working pore canal, a breathing machine access pore canal, a light source access pore canal and a carbon dioxide monitoring pore canal, wherein the sealing component comprises a first ferrule which is sleeved outside the central working pore canal and wraps the central working pore canal, a second ferrule and a third ferrule which are sleeved outside the carbon dioxide monitoring pore canal and wrap the carbon dioxide monitoring pore canal, the first ferrule, the second ferrule and the third ferrule are connected through connecting ropes, a first sealing film and a first backtracking prevention component are arranged in the first ferrule, a first through hole for a medical instrument to pass through is formed in the first sealing film, a second sealing film and a second backtracking prevention component are arranged in the second ferrule, a second through hole for the fiber bronchoscope to pass through is formed in the second sealing film, and a third sealing film is arranged in the third ferrule.
