Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", and the like, indicate positional or positional relationships, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1-3, a subtalar joint brake, includes brake head 1, and brake head 1 is connected with toper main part 3 through joint 2, and brake head 1, joint 2 and toper main part 3 integrated into one piece, and brake head 1, joint 2 and toper main part 3 are inside to run through and are equipped with hollow pipeline 4, and toper main part 3 surface is equipped with screw thread 5, and toper main part 3 keeps away from joint 2 one end and is equipped with mounting groove 6.

The tapered body 3 gradually increases in diameter from the joint 2 toward the other end.

The diameter of the conical main body 3 far away from the joint part 2 is 5-10 mm.

The hollow pipeline 4 is matched with a guide pin, and the guide pin penetrates through the hollow pipeline 4.

The vertical section of the mounting groove 6 is hexagonal, and the mounting groove 6 is matched with an inner hexagonal screwdriver.

The brake head 1, the combining part 2 and the conical main body 3 are all made of titanium alloy materials.

The conical main body 3 of the brake is spirally arranged in the whole process, the diameter of the thread 5 is gradually increased towards the tail part, and the distance between the threads 5 is equal. The brake can be firmly fixed in the tarsal sinus and the tarsal canal of the subtalar joint and is not easy to be released. Meanwhile, the wide equidistant threads 5 avoid damage and pressurization to the subtalar joint. In the transition process of the main body of the stopper from the tail end of the combining part 2, the diameter of the conical main body 3 is gradually increased, the shape of the conical main body is matched with the shape of the sinus of tarsal bones, and the probability of the stopper falling out after operation is reduced.
