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 designs a medical measuring device for measuring the length of the internal structure of the human knee joint. The medical measuring device includes a fixed handle 1, a sports handle 2, a rod 4, a stretch rod 7, and a measuring rule 5. The fixed handle 1 and the moving handle 2 are connected by screws 3, the stretch rod 7 moves in the axial U-shaped groove 41 of the rod 4, one end of the rod 4 is connected to the fixed handle 1, and the other end of the rod 4 is connected to the measuring ruler 5. One end of the stretching rod 7 is connected to the exercise handle 2, and the other end of the stretching 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, and more particularly, to a medical measuring device used for minimally invasive surgery to measure the size of human joints. Background technique [0002] The knee joint is the human body’s largest, most complex structure and function of the trochlear joint. It consists of bone, articular cartilage, soft tissues (crucius ligaments, meniscus), synovial fluid in the joint cavity, attached to the joint capsule, and extra-articular The ligaments are strengthened and formed. The incidence of knee joint injury is relatively high, ranking first among all joint injuries in the human body. In clinical practice, injuries to cruciate ligaments, meniscus and articular cartilage are the most common. 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 popular research fields. [0003] The anterior...
