AI Technical Summary
Technical Problem
In current techniques, the location of the bone tunnel in anterior cruciate ligament reconstruction surgery cannot be accurately determined, resulting in a high failure rate.
Method used
Design an anterior cruciate ligament depth measuring ruler, including a handle and a metal rod, scale lines and a bend. By measuring the highest point of the posterior cartilage edge of the lateral femoral condyle, the center point of the bone tunnel is determined, and precise positioning is achieved in conjunction with a locator.
Benefits of technology
This method enables precise positioning of the bone tunnel, improving the success rate of surgery and reducing the risk of surgical failure.

Abstract
The utility model belongs to the technical field of medical equipment, particularly relates to an anterior cruciate ligament sounding ruler, and aims to solve the problem of high failure rate of an operation caused by inconvenience in accurate positioning of a bone tunnel position in the prior art, and provides the following scheme: the anterior cruciate ligament sounding ruler comprises a handle; one end of the metal rod is fixedly connected with the handle; the first scale line, the second scale line and the third scale line are all arranged on the outer side of the metal rod, the outer side of the handle is connected with an anti-skid pad, a first bending section is arranged on the metal rod, the angle of the first bending section is 160-170 degrees, a second bending section is arranged on the metal rod, the angle of the second bending section is 90 degrees, and the angle of the third bending section is 90 degrees. According to the bone tunnel positioner, a positioning point of a bone tunnel can be accurately found, then the bone tunnel is formed through the positioner, the bone tunnel positioner is simple in structure and convenient to use, the quality of the bone tunnel is improved, and the operation failure rate is greatly reduced.
