Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 , as shown in 2, in the orthopedic orthopedic surgery of the present invention, the special tool for the installation of a figure-of-eight board is built-in, comprising a positioning pin 1, an angle meter 2 of a double guide hole instrument, a figure-of-eight template 3, a double guide hole instrument 4, and a figure-of-eight plate clamp pliers etc.

[0019] A guide hole column of the double guide hole instrument 4 is fixedly connected with an angle meter 2 of the double guide hole instrument. There is positioning pin 1.

[0020] After the surgical incision, insert the positioning needle 1 into a specific part of the exposed bone, place the figure-of-eight template 3 through the positioning pinhole on the figure-of-eight template 3, and place the double guide hole instrument with the function of adjusting the angle through the pos...

Abstract

The invention relates to a special installation tool of an internally-installed splayed plate in an orthopaedic corrective surgery, comprising a positioning needle, a splayed template, a double-guide hole meter and an inclinometer of the double-guide hole meter, wherein one guide hole pillar of the double-guide hole meter is fixedly connected with the inclinometer of the double-guide hole meter; the bottom of the guide hole pillar is connected with the splayed template; and the positioning needle is inserted between the inclinometer of the double-guide hole meter and the splayed template. When drilling hole, the front end of the splayed template is fixed by using a splayed plate tongs, wherein when the splayed plate tongs clamp, two grips positioned on the head of the splayed plate tongs are parallel, the distance between the two grips is the distance between two clamped surfaces of the splayed template, and two bulges positioned on the head of the splayed plate tongs support against grooves positioned on the two clamped surfaces of the splayed template. The special installation tool designed according to the dimensions of the splayed plate and the splayed template greatly enhances the installation position accuracy rate and the installation efficiency of the splayed plate; and in addition, the invention has compatibility with the splayed plate and can reduce the workload of a doctor, enhance the accuracy and reduce the bone injury of a patient by using the tool in the installation process.

Description

technical field [0001] The invention relates to a medical operation tool, in particular to a special tool for installing a built-in 8-shaped board in orthopedic orthopedic operations. Background technique [0002] At present, there is no suitable special tool for the installation of figure-of-eight plates in orthopedic deformity correction surgery. During the installation process, the doctor's workload is heavy, and the accuracy is low, which is easy to increase the bone damage of the patient. Contents of the invention [0003] The present invention aims to provide a special tool for installation with a built-in 8-shaped board in orthopedic orthopedic surgery, so as to reduce the workload of doctors, improve accuracy and reduce bone damage of patients. [0004] In order to achieve the above object, the technical solution of the present invention is: a special tool for the installation of a built-in figure-of-eight plate in orthopedic orthopedic surgery, including positioni...
