Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an extraction impactor. Background Technique

[0002] Impact extraction is an extraction technique that uses the energy generated by high-speed instruments to cut and fragment teeth, mainly used for quickly removing complex teeth that are difficult to extract, such as impacted wisdom teeth. This method reduces the pain response caused by direct violence, improves the surgical efficiency, and reduces the discomfort of patients.

[0003] Patent Application No.: 202020124656.5 proposes an extraction impactor, which includes a rod-shaped body. The body is divided into a handle part, a connecting rod part, and a blade part. The blade part includes several blade teeth evenly arranged around the central axis of the body, and a force-receiving plane is provided at one end of the body away from the blade part. The extraction impactor proposed by the utility model has a stable contact between its working end and the tooth surface, prevents the working end from slipping, and transmits the impact force stably, especially suitable for impact extraction.

[0004] This device still has some deficiencies. For example, it requires staff to gently tap the body with a bone hammer to impact the patient's teeth, which not only increases the work intensity of the staff, but also makes it difficult for the staff to ensure stable force application after long-term tapping work. If the force is too large, it is easy to damage the patient's gums, and the patient's gums may bleed during impact extraction, affecting the staff's observation. Content of the Utility Model

[0005] The purpose of the utility model is to provide an extraction impactor to solve the problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

The bottom end of the impact rod extends below the main body rod, and a plurality of impact blades are evenly installed on the bottom surface of the impact rod. A connecting plate is fixedly installed at the center of the bottom surface of the impact rod, and a connecting plate is fixedly installed at the top end of the impact rod. A vibration motor is fixedly installed on the top wall of the impact groove. The bottom end of the output shaft of the vibration motor is fixedly installed with a pressing plate, and the pressing plate abuts against the surface of the connecting plate. A spring is sleeved on the outer surface of the impact rod. The bottom end of the spring is fixedly connected to the bottom wall of the impact groove, and the top end of the spring is fixedly connected to the bottom surface of the connecting plate.

[0008] Preferably, an anti-slip sleeve is sleeved on the outer surface of the main body rod.

[0009] Preferably, a storage cavity is formed inside the impact rod. A connecting pipe is connected to the bottom wall of the storage cavity. The storage cavity is communicated with the nozzle through the connecting pipe, and a micro water pump is arranged on the connecting pipe.
