Abstract

The tarsal sinus stabilizer comprises a main nail body, a cylindrical through cavity is formed in the axis of the main nail body, the two ends of the cylindrical through cavity expand outwards to form a first circular truncated cone cavity and a second circular truncated cone cavity respectively, and the tarsal sinus stabilizer further comprises a first nail body and a second nail body; the first nail body comprises a first circular truncated cone body and a first screw rod which are connected with each other, the second nail body comprises a second circular truncated cone body and a second screw rod which are connected with each other, the side wall of the first circular truncated cone body is attached to the inner wall of the first circular truncated cone cavity, and the side wall of the second circular truncated cone body is attached to the inner wall of the second circular truncated cone cavity; the first screw rod and the second screw rod are respectively inserted from two ends of the cylindrical through cavity, the second screw rod is inserted into an axis through cavity formed by the first screw rod, and the outer wall of the second screw rod is in threaded connection with the inner wall of the axis through cavity. The threads of the two screw rods are continuously tightened, and the main nail body is expanded to the required diameter.

Description

technical field [0001] The present application relates to orthopedic surgery, in particular to a sinus tarsi stabilizer for talus inversion. Background technique [0002] The sinus is a slightly tapered interosseous space located between the posterior calcaneal joint, the anterior calcaneal joint, and the middle calcaneal joint, running from the posterior medial to the lateral. Its inner side is the funnel-shaped sinus tarsus, and the back of the sinus tarsus is immediately adjacent to the tarcar process. Among the major structures are the fat pads, small blood vessels, small lymphatic articular capsules, nerve endings, bursa, intercalcaneal and talar ligaments, cervical ligaments, and the medial, medial, and lateral roots of the subextensor retinaculum. [0003] The tarsal sinus is a slightly conical bony space located between the posterior calcaneal joint and the anterior and middle joints, running from the back to the outside. Its inner side is the funnel-shaped sinus t...
