Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] see figure 1 , Figure 1A , Figure 1B , Figure 1C , Figure 1D As shown, the present invention has designed a kind of medical measuring instrument for measuring the internal structure length of human knee joint, and this medical measuring instrument comprises fixed handle 1, motion handle 2, pole 4, stretch rod 7, measuring ruler 5. The fixed handle 1 is connected with the moving handle 2 through the screw 3, the stretch rod 7 moves in the axial U-shaped groove 41 of the pole 4, one end of the pole 4 is connected with the fixed handle 1, and the other end of the pole 4 is connected with the measuring ruler 5. One end of the stretch rod 7 is connected to the motion handle 2, and the other end of the stretch rod 7 is connected to the measuring ruler 5.

Abstract

The invention discloses a medical measuring device for measuring the structure size in a human joint. A fixed handle and a movable handle of the medical measuring device are connected through screws, a stretching rod moves in a U-shaped groove of a boring rod, one end of the boring rod is connected with the fixed handle, one end of the stretching rod is connected with the movable handle, and the other end of the boring rod and the other end of the stretching rod are connected with a measuring ruler. The medical measuring device can be used for measuring the width and the height of the intercondylar fossa of a knee joint, the length and the diameter of an anterior cruciate ligament, the shape and the position of the ligament and the like, obtaining of clinical dissection parameters is facilitated, and the clinical effects of a patient are improved.

Description

technical field [0001] The present invention relates to a medical device, more particularly to a medical measuring device used for minimally invasive surgery for measuring the size of the internal structure of a human body joint. Background technique [0002] The knee joint is the largest trochlear joint with the most complex structure and function in the human body. Formed by strengthening ligaments. The incidence of knee joint injury is relatively high, ranking first among all joint injuries in the human body, and the injuries of cruciate ligament, meniscus and articular cartilage are the most common clinically. Therefore, the anatomy, imaging and clinical research of the knee joint have received more and more attention in recent years, and various related researches are also currently hot research fields. [0003] The anterior cruciate ligament (ACL) is the most important forward stabilizing structure of the knee joint. After injury, it can produce obvious forward insta...
