Background
The nasal endoscope operation is one of the most frequently performed operations of a nasal surgeon, and has the advantages of small damage, no incision on the skin of the head and the face, quick recovery and the like. At present, most nasal cavity, nasal sinuses, nasopharyngeal diseases, skull base tumor and the like can be treated by operation under the monitoring of an endoscope. The operation method is to introduce an endoscope and surgical instruments into the narrow anterior nares for operation, and blood, smoke and the like generated in the operation need to be removed in time so as to ensure clear operation visual field.
The traditional clearing method is to insert a negative pressure suction tube through the anterior nares to suck blood and smoke in time, but the method causes the originally narrow operation space to be more crowded, and the nasal endoscope operation is mostly operated by one hand, so the blood suction and the operation cannot be performed synchronously, and the operation must be stopped temporarily when the blood and the smoke are sucked, thereby delaying the operation progress. In addition, repeated insertion and extraction of the suction tube through the anterior naris is also likely to cause damage to the anterior naris and nasal mucosa, resulting in postoperative nasal adhesion, and for more relevant contents of the prior art, reference may be made to chinese patent document CN 204193254U.
However, the nasopharyngeal suction tube in the prior art has the following disadvantages:
1. the medicine is difficult to be directly introduced into the nasopharynx part and can be inserted into the nasopharynx part through the mouth only by being pulled by other instruments;
2. when the suction tube is blocked by blood clots, the suction tube must be replaced or detached and dredged before being installed again, which delays the operation progress.

Detailed Description
In the prior art, the suction tube of the nasopharynx part is soft and difficult to be directly introduced into the nasopharynx part, and can be inserted into the nasopharynx part through mouth only by being pulled by other instruments; when the suction tube is blocked by blood clots, the suction tube must be replaced or detached and dredged before being installed again, which delays the operation progress.
Therefore, the present invention provides a new solution, which will be described in detail below with reference to the accompanying drawings for better clarity.
The first embodiment is as follows:
referring to fig. 1 to 3, in the present embodiment, the first end includes asuction hole 3; the second end comprises asuction port 10 and a flush port 11.
In this embodiment, thesuction port 10 and the flushing port 11 are connected by a three-way pipe, and the three-way valve 2 controls the working states of thesuction port 10 and the flushing port 11, i.e., the switching between the suction function and the flushing function.
In this embodiment, it is preferable that thesuction port 10 and the three-way connection pipe are at an angle of 180 degrees, the flush port 11 and thesuction port 10 are at an angle of 90 degrees, and the flush port 11 and the three-way connection pipe are at an angle of 90 degrees, i.e. in a T-shaped connection (see fig. 2 in particular).
In the present embodiment, the arc-shaped connection tube 4 is disposed between the first end and the second end, and the angle range is 60 degrees to 120 degrees, so that the first end and the second end are too natural to be easily blocked by blood clots and the like. When the nasopharynx oral cavity inserting device is used, the first end can be directly inserted into the nasopharynx through the mouth without traction of other instruments, time is saved, and efficiency is improved.
In the present embodiment, thesuction holes 3 face the nasal cavity, and blood, smoke, and wash fluid are sucked through one suction hole.
In the present embodiment, the length from the first end to the arc-shaped connectingtube 4 is the distance from the oropharynx to the nasopharynx; the length from the second end to the arc-shaped connectingpipe 4 is longer than the distance from the oropharynx part to the upper incisor, so that thesuction port 10 and the flushing port 11 are both outside the mouth, and the operation is convenient.

After the operation is started, the three-way valve 2 is used for controlling the three-way pipe to be turned to thesuction interface 10, the flushing interface 11 is temporarily closed, the suction function is executed, blood and flushing liquid generated in the operation and smoke generated by the electrocoagulation device can be continuously sucked, and the operation visual field is ensured to be clear.
In the operation process, when first end attractshole 3 to be stopped up by the clot, need not to dismantle and attracts the pipe, only need to turn to the tee bend pipe through three-way valve 2 control and wash interface 11, temporarily seal and attractinterface 10, carry out the flushing function, connect with the syringe and wash interface 11, inject into normal saline and can wash out the clot that blocks and attracthole 3, accomplish the operation of mediation jam position.
Example two:
referring to fig. 4, the embodiment further provides a nasopharynx section suction tube with a flushing port 11, which is provided with amain suction hole 30 and at least one lateralauxiliary suction hole 31, and the main suction hole and the auxiliary suction hole (30 and 31) can be matched with each other, so that the efficiency of sucking smoke, blood and flushing fluid is improved, and the blocking probability of the suction tube is reduced.
In the present embodiment, the shape of thesub suction holes 31 is preferably square.
It is understood that either theprimary suction holes 30 or thesecondary suction holes 31 may also be oval or circular. And various combinations can be carried out according to the requirements of practical application.
In this embodiment, thesuction port 10, the flushing port 11 and the three-way connection pipe form an angle of 120 degrees with each other, and reference may be made to a logo pattern of a "galloping" automobile.
Other contents of this embodiment are similar to those of the previous embodiment, and may be referred to each other.
