Background

Early surgery was limited to simple manual methods of cutting, incising, and suturing the body surface, such as abscess drainage, tumor excision, and trauma suturing. Surgery is a procedure that destroys the integrity of tissue (incision), or restores the integrity of the destroyed tissue (suture). With the development of surgery, the field of surgery is expanding and can be performed at any part of the human body. The applied instruments are also updated continuously, such as scalpels including electric scalpels, microwave scalpels, ultrasonic scalpels, laser scalpels and the like. When the surgery for treating the heart pre-excitation syndrome is performed, the location can be realized by means of a high-function electronic computer. Some surgical operations do not necessarily require cutting to destroy tissues, such as removal of stones or foreign bodies in the biliary tract, urinary tract or gastrointestinal tract by various endoscopes; dilation of coronary arteries with balloons via puncture catheters, recanalization of occluded vessels with laser, and the like. Therefore, surgery also has a broader meaning. However, most of the current operations are mainly performed by the manual operation of the physician.

Lateral bending rongeur is used for biting and removing, repairing bone tissues, one of medical instruments commonly used in orthopedic surgery is made, the existing lateral bending rongeur mainly uses a spring piece to keep a tong body in a separated state, so that a certain included angle is formed at the cutting part of the lateral bending rongeur, and further the lateral bending rongeur is convenient to use in surgery, the spring piece is mainly formed by processing spring steel, in the repeated use process, the spring piece can cause deformation to a certain degree due to stress, so that the included angle of a main tong body can be reduced, the accuracy degree of the rongeur is caused, the lateral bending rongeur hand in the traditional Chinese medicine growth time in the surgery process can be fatigue, and the doctor can be caused to have accidents in surgery.
