Problems solved by technology

[0003] In the traditional method, the surgeon usually drills a hole from the middle of the lateral patella based on experience. Although this method has a certain effect, the accuracy of this method is low, and it is easy to make the hole off the top or bottom of the patella, which affects the follow-up. Fixed operation, which brings inconvenience to the operation of patients

Abstract

The invention discloses a clamp-type patella anchor guider, relates to the field of medical instruments, and solves the shortcomings of drilling from the middle of the lateral position of patella according to experience. The product comprises a push rod, a main body, a movable part, a top plate, an adjustment screw and a guiding tube, the push rod is installed on the upper part of the main body, the movable part is hinged to the lower part of the main body, the top plate is installed at the bottom end of the main body and a fine adjustment knob is arranged between the top plate and the main body in a screwing mode, both the adjustment screw and the guiding tube are hinged to the main body, and the lower part of the adjustment screw is in screwing connection with a second fine adjustment knob. The product provides a better fixing effect by a first elastic pad on a clamping jaw and the top plate, and ensures that the relative position of the guider and the patella is unchanged after being fixed; the product ensures the accuracy of the drilling position through the fine adjustment of the components on one side of the guiding tube; and the product is simple in structure, convenient tooperate and high in positioning precision, effectively improves the operation efficiency in the operation, and improves the fixation effect of the patella anchor.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a clamping type patella anchor guider. Background technique [0002] With the advancement of medical technology, at present, operations such as patella fixation and repair are mostly carried out using minimally invasive methods. Minimally invasive methods refer to the methods of diagnosis and treatment of spinal diseases through non-traditional surgical methods with the help of special surgical instruments, instruments or other means. It is a technology that only causes minimal trauma to the patient during the treatment process and leaves only minimal wounds after the operation. Wherein, when the lateral position of the patella is fixed, pre-drilled holes are required to facilitate the fixation of the anchor. [0003] In the traditional method, the surgeon usually drills a hole from the middle of the lateral patella based on experience. Although this method has a certain effec...
