Medical impact hammer

Abstract

The invention discloses a medical impact hammer, and belongs to the field of experiment measuring techniques and the field of medical apparatuses. The medical impact hammer comprises an electromagnetic power hammer, a guide sleeve, an electromagnetic coil, a housing, a spring, a handle, an osteotome adapter, a controller, a gear switch and a start-up button, wherein the start-up button is mountedat the position of a thumb, on the handle; the gear switch is mounted at a position adjacent to the housing, of the handle, and comprises three gears including a strong gear, a medium gear and a weakgear; an electromagnetic power hammer body is a cylinder; and a head hitting location is a hemispheroid, and cooperates with the guide sleeve through an air gap. The medical impact hammer disclosed bythe invention adopts an electromagnetic force compression spring for energy storage; and when the electromagnetic force is released, the electromagnetic power hammer is pushed by the spring to implement beating on an osteotome, artificial factors are eliminated, and the controllability and the stability of the knocking force are improved. An impact hammer which cooperates with the osteotome workfor usage and of which the impact force is stable and controllable is provided for surgeries in orthopaedics and dentistry including sinus lift and the like, so that the safety and the validity of theusing of the osteotome in the surgeries are improved, the surgery efficiency is improved, and the medical care risk is reduced.

Description

technical field

[0001] The invention belongs to the field of testing technology and medical equipment, and relates to an electric impact hammer used for striking an osteotome when medical personnel perform orthopedic and dental operations such as maxillary sinus floor lifting. Background technique

[0002] Osteotome is a commonly used surgical tool in clinical practice of orthopedics and dentistry. In the common maxillary sinus floor lifting operation in the treatment of oral diseases, the force control requirements for medical personnel using the osteotome are relatively high, and the percussion force needs to be moderate. Controllable, if the force is too small, the desired effect cannot be achieved, but if the force is too large, the risk of perforation and infection of the maxillary sinus mucosa will be increased. Existing osteotomes often use a simple solid steel hammer for percussion, and the control of the percussion force depends entirely on the operator's personal f...
