Medical steel plate pre-bending device for orthopedic clinics

Abstract

The invention discloses a tool for orthopedic clinics, and in particular discloses a medical steel plate pre-bending device for orthopedic clinics; the pre-bending device is composed of a main body, a rotary arm, a pressing arm and a plurality of bending rollers, wherein the main body is composed of a base plate and a vertical plate; shaft holes A are uniformly distributed in the inner sidewall of the vertical plate; a shaft pin A is arranged at the front end of the rotary arm, and a handle is arranged at the back end; multiple groups of inserting holes are formed in the inner sidewall of the rotary arm; a plurality of bolts are arranged on he inner sidewall of the pressing arm; the pressing arm is combined to the inner side of the rotary arm in a cross mode; a shaft hole B is formed in the outer side of the lower end of the pressing arm; the bending rollers are composed of roller bodies and shaft pins B; the bending rollers can be combined to the inner side of the vertical plate so as to support a medical steel plate; and in additional, the bending rollers can be fixedly arranged at the lower end of the pressing arm so as to provide bending pressure to the medical steel plate. The pre-bending device disclosed by the invention is good in bending effect, high in efficiency, relatively labor-saving in operation and relatively convenient in regulation, and the pre-bending device is good in adaptability to medical steel plates on various parts and of various specifications; and the pre-bending device can reduce, and can even avoid, the circumstance that the medical steel plate is discarded during pre-bending, and the pre-bending device is suitable for clinical purchasing for clinical use.

Description

technical field [0001] The invention relates to a medical device, in particular to a device which can be used for pre-bending various medical steel plates in orthopedic clinics. Background technique [0002] In orthopedic clinics, plate and screw internal fixation is a relatively common treatment method, and it is mostly used for cases where manipulative reduction and external fixation fail, especially for long-bone bone fractures in limbs. In plate and screw internal fixation, the shape of the medical plate should match the physiological curvature of the fracture site, thereby ensuring good fit between the medical plate and the broken bone, improving the fixation effect of the broken bone and the firmness of the medical plate after screw fixation However, most of the current medical steel plates are processed according to the location and specifications, and it is difficult to take into account the physiological differences in different cases. necessary action before.

In plate and screw internal fixation, the shape of the medical plate should match the physiological curvature of the fracture site, thereby ensuring good fit between the medical plate and the broken bone, improving the fixation effect of the broken bone and the firmness of the medical plate after screw fixation However, most of the current medical steel plates are processed according to the location and specifications, and it is difficult to take into account the physiological differences in different cases. necessary action before

At present, there is no professional pre-bending device for medical steel plates in clinical practice, and most of them use simple tools such as wrenches and pliers to bend medical steel plates. On the one hand, it is difficult to ensure the accuracy of bending position and bending angle, which affects On the other hand, when the above tools are used to bend the medical steel plate, it is easy to cause damage to the surface of the medical steel plate, such as debris or burrs, which directly lead to the scrapping of the medical steel plate; Bending processing operation is more troublesome, less efficient and more laborious

[0003] Relatively professional steel plate bending devices do exist, but most of them are complex in structure, bulky, high in purchase cost, and relatively professional in operation requirements. In view of the above factors, they are usually used for batch processing in factory workshops, and are extremely unsuitable for industrial applications. Orthopedic clinical use
