[0014] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] See also Figure 1-2 As shown, a conveniently operated ulna, radio and fibular intramedullary nail comprises a nail body 3, a guide hole slot 4 is formed on the nail body 3, and a strip hole 5 is formed on one side of the middle portion of the nail body 3, a hammering auxiliary rod 9 is disposed in the guide hole slot 4, an auxiliary guide block 7 is disposed in the strip hole 5, and an auxiliary handle rod 8 is mounted on one side of the auxiliary guide block 7, and a countersunk hole 14 is formed at the bend of the external end portion 1 on the nail body 3;

[0018] By setting a guide hole groove 4 on the nail body 3 and combining it with a hammer auxiliary rod 9 that can be placed in the guide hole groove 4, a force-applying hammering point is provided for driving the internal nail, thereby solving the problem of inconvenience in applying force when the internal nail is embedded in the bone body. At the same time, the auxiliary guide block 7 located at the end of the auxiliary handle rod 8 is extended into the strip hole 5, which is convenient for the operator to position the nail head 2 of the internal nail and guide the auxiliary internal nail for stable implantation.

[0019] like Figure 1 As shown, the external end portion 1 is distributed with a through hole 11, a through hole 2 12 and a through hole 3 13, and the nail body can be laterally fixed through the provided through holes.
