Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to an Achilles tendon locator. Background Art

[0002] The Achilles tendon is the longest and strongest tendon in the human body, and the incidence of rupture is also high, mostly caused by sports injuries. It is a common orthopedic disease. In order to avoid causing greater damage to the blood supply and peritendinous tissues of the Achilles tendon, minimally invasive surgery is currently used to repair the Achilles tendon. Although there are many types of Achilles tendon locators on the market today, most products generally only have adjustable inner clamping claws, while the outer clamping claws are fixed; or both the inner and outer clamping claws are adjustable, but they must be adjusted at the same time. Due to different physiques of people, it may not be suitable for people with large physiques, and for people with small physiques, it can only effectively clamp and position the Achilles tendon, but cannot clamp the extended part of the triceps surae, which increases the difficulty of threading and reduces the efficiency of the operation.
