Description

Technical Field

[0001] The utility model relates to the technical field of oral instruments, in particular to a maxillary sinus perforation obstructor which is convenient for removing cut roots. Background Art

[0002] Clinically, maxillary sinus perforation is prone to occur during the extraction of maxillary posterior teeth. However, at this time, there are still broken roots or broken roots of maxillary impacted teeth that have not been extracted. Since the broken roots are close to the perforation and the patient is in a tilted head position during tooth extraction, the broken roots are located above the maxillary sinus. During the root extraction process, the broken roots are very likely to fall into the maxillary sinus. For this reason, clinicians may temporarily give up on continuing to extract the roots and wait until the perforation heals before removing the broken roots. However, there may be a risk of inflammation in the long term and affect the later implant restoration, causing patients' distrust. Utility Model Content

[0003] In order to solve the defects of the above-mentioned prior art, the utility model provides a maxillary sinus perforation blocker which is convenient for removing the severed root, and is used for blocking the perforation to facilitate the safe removal of the severed root.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0005] A maxillary sinus perforation blocker which is convenient for removing severed roots comprises a blocking body and an air filling rod. The blocking body is composed of two hollow tubes connected at an angle to each other. A balloon is connected to the front end of the blocking body, and the air filling rod is inserted into the rear end. The air filling rod is gap-matched with the hollow tube, and a push handle is provided at the end.

[0006] Furthermore, the length of the gas filling rod is smaller than the length of the inserted hollow tube.

[0007] Furthermore, the included angle between the two hollow tubes is 120°-180°.

[0008] Furthermore, the balloon is a transversely inflatable airbag.

[0009] Furthermore, the diameter of the front end of the blocking body is less than 5 mm.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model inserts the front end of the blocking body above the perforation so that the balloon slightly protrudes into the maxillary sinus, and compresses the gas in the blocking body to expand the balloon by pushing the pressure rod to block the perforation. At this time, the broken root can be safely removed to prevent it from falling into the maxillary sinus during the removal process. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] In the description of the embodiments of the present application, it should be noted that the indicated orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the application is usually placed when in use, or is the orientation or position relationship commonly understood by technical personnel in this field. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0017] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0018] like Figure 1As shown, a maxillary sinus perforation blocker convenient for removing severed roots comprises a blocking body 1 and an air filling rod 2. The blocking body 1 is composed of two hollow tubes 11 connected at an angle to each other. In order to facilitate the blocker to extend into the tooth extraction socket to block the perforation without affecting the tooth extraction operation and blocking the operation field of view, the angle A can be set to 120°-180°. According to the physiological characteristics of the human oral cavity and the perforation diameter, the tube diameter D at the front end of the blocking body 1 is set to be less than 5mm and connected with a balloon 3. The air filling rod 2 is inserted into the rear end of the blocking body 1. The air filling rod 2 is clearance-matched with the hollow tube 11, and can both slide in the hollow tube 11 and compress the gas in the tube. A push handle 4 is provided at the end of the air filling rod 2. The length of the air filling rod 2 is less than the length of the inserted hollow tube 11, so that it can only slide in the hollow tube 11.

[0019] When in use, first insert the front end of the blocking body 1 above the perforation, and the balloon slightly protrudes into the maxillary sinus. At this time, the balloon 3 is in a deflated state, and then the gas filling rod 2 is inserted into the hollow tube 11. The pressurizing rod 2 is pushed to compress the gas in the blocking body 1 forward to expand the balloon 3. The balloon 3 is a transversely expanding balloon, which transversely blocks the perforation. At this time, the broken root can be safely removed to prevent it from falling into the maxillary sinus during the removal process.

[0020] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
