The operation is performed without direct vision of a nasal endoscope, and there is a problem of inaccurate packing position, which affects the mucosal contraction effect, and further increases the probability of intraoperative and postoperative bleeding. Utility Model Content
[0005] The utility model aims to solve the problem in the prior art that before and after dacryocystitis surgery on patients, a pusher is required to push brain cotton containing anesthetics and nostril contraction to the middle nasal meatus, so as to fully contract the nasal mucosa and prevent intraoperative and postoperative nasal mucosal bleeding. Ophthalmologists usually use nasal stents, gun-shaped forceps, brain cotton, anesthetics and nasal contraction drugs to complete the operation in steps. The process is cumbersome and takes a long time. Patients feel obvious pain during the process of stretching the nostrils. There are many types of drugs and disinfection instruments, which are costly. The operation is performed without direct vision of a nasal endoscope, and the packing position is inaccurate, which affects the mucosal contraction effect and further increases the probability of intraoperative and postoperative bleeding.
[0006] In order to solve the above technical problems, the utility model provides a brain cotton pusher for packing the front nares, comprising: a push tube and an adjusting device, the cross-section of the push tube is elliptical, the two ends of the push tube are respectively contracted and expanded, one end of the inner wall of the push tube is slidably connected with a push rod, the inner wall surface of the push tube is slidably connected with a brain cotton body, the brain cotton body is an expansion sponge, the adjusting device comprises a line, one end of the line is fixedly connected to one end of the brain cotton body, a through hole is opened on the closed surface of the push tube, the surface of the line slides through the through hole, and the surface of the end of the brain cotton body close to the line abuts against one end of the push rod.
[0007] The effect achieved by the above components is: before and after the dacryocystitis surgery on the patient, a pusher is needed to push the brain cotton containing anesthetics and shrinking the nostrils to the middle nasal meatus, fully shrink the nasal mucosa, and prevent intraoperative and postoperative nasal mucosal bleeding. Ophthalmologists usually use nasal stents, gun-shaped forceps, brain cotton, anesthetics, and nasal shrinkage drugs to complete the operation in steps. The process is cumbersome and takes a long time. The patient feels obvious pain during the process of stretching the nostrils. There are many types of drugs and disinfection instruments, which are expensive. The operation is performed without direct vision of the nasal endoscope, and the packing position is inaccurate, which affects the mucosal shrinkage effect. At this time, the push tube with the entire surface coated with lubricant is first sent into the patient's nasal meatus along the patient's nasal meatus.

The thin front and thick back push tube fits the structure of the human nasal cavity and is easy to push in. Then, the push rod at one end of the push tube is squeezed to make the push rod slide, thereby driving the brain cotton body on the inner wall of the push tube to move its position, allowing the entire brain cotton body to enter the patient's nasal cavity. Since the brain cotton body is an expanded sponge, its volume is smaller before push injection. After the injection is injected into the predetermined position of the nasal cavity, the expanded sponge can better fit the nasal cavity. When the brain cotton body needs to be replaced later, lightly pull the line at the tail to pull it out of the nasal cavity and replace it with a new brain cotton body.
[0008] Preferably, the arc surface of the push injection tube is provided with two injection holes, and the arc surface of the brain cotton body is provided with drainage holes at positions corresponding to the injection holes.

[0010] Preferably, one end of the brain cotton body close to the opening of the push tube is fixedly connected with a guide block, and the cross-section of the guide block is in a pointed cone shape.
[0011] The effect achieved by the above components is that in the process of pushing the brain cotton main body in the push injection tube, the nasal resistance can be effectively reduced through the pointed cone-shaped guide block fixed at one end of the brain cotton main body.
[0012] Preferably, a scale is provided on one side of the arc surface of the injection tube.
[0013] The effect achieved by the above components is that the position where the push tube enters the nasal passage can be clearly observed by using the scale provided on the surface of the pusher, so as to facilitate better operation and use.
[0014] Preferably, the arc surface of the injection tube is slidably connected to a limiting ring, and the limiting ring is a silicone ring.
[0015] The effect achieved by the above components is that the limiting ring made of silicone material can block the injection tube after it enters the nasal passage to a specified depth.
[0016] Preferably, both sides of the inner wall of the push injection tube are fixedly connected to limiting columns, and limiting holes are opened on the arc surface of the brain cotton body corresponding to the position of the limiting columns, and the inner wall of the limiting hole is slidably plugged into the surface of the limiting column.
[0017] The effect achieved by the above components is that the limiting column fixed on the inner wall of the push tube can be plugged into the limiting hole opened on the surface of the brain cotton body to avoid position deviation of the brain cotton body in the push tube.
[0018] Preferably, the push injection tube is a polypropylene transparent tube to improve the strength of use.
[0019] The effects achieved by the above components are: the injection tube made of polystyrene material has good flexural strength and a smooth surface, which is conducive to better entry into the nasal passage, and the diameter of the contracted end of the injection tube is 0.7 cm, and the diameter of the flared end of the injection tube is 1.2 cm. The injection tube, which is thin at the front and thick at the back, fits the structure of the human nasal cavity and is easy to push in.
[0020] Compared with the related art, the anterior nasal packing brain cotton pusher provided by the utility model has the following beneficial effects:
[0021] The utility model provides a brain cotton pusher for packing anterior nasal cavity. Before and after a dacryocystitis operation is performed on a patient, the brain cotton containing anesthetics and shrinking the nostrils needs to be pushed into the middle nasal cavity by means of a pusher to fully shrink the nasal mucosa and prevent intraoperative and postoperative nasal mucosal bleeding. However, ophthalmologists usually use nose support, gun-shaped forceps, brain cotton, anesthetics, and nasal shrinkage drugs to complete the operation in steps. The process is cumbersome and takes a long time. The patient feels obvious pain during the process of stretching the nostrils. There are many types of drugs and disinfection instruments used, which are costly. The operation is performed without direct vision of a nasal endoscope, and the packing position is inaccurate, which affects the shrinkage effect of the mucosa. At this time, the drug to be injected is first injected into the brain cotton body through the injection hole opened on the surface of the push tube, and then the entire push tube is inserted along the patient's The nasal passage is sent into the patient's nasal cavity, and the position is fixed by the limiting ring on the surface of the injection tube. Then, the push rod at one end of the injection tube is squeezed to allow the push rod to drive the brain cotton body on the inner wall of the injection tube to move. At this time, the pointed cone-shaped guide block fixed at one end of the brain cotton body can effectively reduce the resistance to entering the nose, so that the entire brain cotton body can easily enter the patient's nasal cavity. When the brain cotton body needs to be replaced later, the line at the tail can be gently pulled to pull out the nasal cavity and replace it with a new brain cotton body. Through the operation of the adjusting device, the integrated injection of drug brain cotton for anterior nasal packing is achieved, which reduces the pain of repeated nasal support to open the nostrils, and at the same time, the brain cotton body is simply and clearly pushed to the part of the nasal cavity that needs to be packed.
