Abstract
The utility model discloses a hollow locking nail used for fracture treatment. The hollow locking nail comprises a base body (100) and a guide hole (200) penetrating the axis of the base body (100), wherein, the base body (100) at least comprises a screw thread section (110); and screw threads (111) are formed on an outer rotary surface of the screw thread section (110). The hollow locking nail has the advantages that as the guide hole is formed in the locking nail, the locking nail is sleeved on a guide needle and is screwed into a screw hole of a locking plate along the guide needle during clinical fracture treatment, so that the locking nail is guaranteed to be completely screwed into the screw hole, screw teeth of the locking nail are guaranteed to be completely combined with those of the locking plate, ideal and firm internal fixation can be achieved, and the occurrence of the phenomenon of damage of the locking nail and the locking plate can be reduced.
Description
Technical field
This utility model relates to a kind of hollow locking nail that is used for fractures.
Background technology
Existing fracture clinical treatment often need use locking nail, and described locking nail and lockplate are used.When locking nail and lockplate are used, because lockplate screw direction is special, be difficult for when locking nail is screwed into being screwed into according to the screw correct direction, therefore can have following deficiency: 1, locking nail can not be screwed into fully; 2, the locking nail thread is fragile.
The utility model content
This utility model provides a kind of hollow locking nail that is used for fractures, and it has overcome the existing deficiency of the locking nail in the background technology.
The technical scheme that is adopted that this utility model solves its technical problem is:
A kind of hollow locking nail that is used for fractures, it comprises that a matrix (100) and runs through the pilot hole (200) of matrix (100) axis, and described matrix (100) comprises a thread segment (110) at least, and the outer surface of revolution of described thread segment (110) is established screw thread (111).
Among one preferred embodiment: described matrix (100) also comprises one affixed section (120), and described thread segment (110) has be spirally connected an end (112) and a fixed connecting end (113), and described fixed connecting end (113) and affixed section (120) are affixed.
Among one preferred embodiment: described pilot hole (200) is divided into the circle segments (210) of a corresponding thread segment (110) and the non-circular section (220) of corresponding affixed section (120).
Among one preferred embodiment: described non-circular section (220) is common hex slot section or Flos Mume hex slot section.
Among one preferred embodiment: the end (112) that is spirally connected of described thread segment (110) is set as tapping screw thread.
The technical program is compared with background technology, and it has following advantage:
1, owing to establishes pilot hole in the locking nail, when therefore fracturing clinical treatment, locking nail is socketed in guide pin, be screwed into the lockplate screw along guide pin, then can guarantee correctly to be screwed into, can guarantee to be screwed into fully, can guarantee the complete combination of thread of the thread and the lockplate of locking nail, can reach desirable and strong internal fixation, the damage phenomenon that then can reduce locking nail and lockplate takes place, and can realize the operation technique simplicity;
2, pilot hole is divided into circle segments and non-circular section, then can tighten locking nail by non-circular section, and easy to operate, the working place is little, is convenient to operation and uses.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the generalized section of the hollow locking nail of a preferred embodiment.
The specific embodiment
Please refer to Fig. 1, it has illustrated the generalized section of the hollow locking nail of a preferred embodiment.A kind of hollow locking nail that is used for fractures, it comprises that a matrix 100 and runs through the pilot hole 200 of matrix 100 axis.
Described matrix 100, it comprises the thread segment 110 that is fixed together and one affixed section 120.
The described thread segment 110 outer surfaces of revolution are established screw thread 111.Described thread segment 110 have one be spirally connected the end 112 and one fixed connecting end 113.Among the present embodiment, the end 112 that is spirally connected of described thread segment 110 is set as tapping screw thread, establishes tapping screw thread, conveniently is screwed into.And described fixed connecting end 113 and affixed section 120 are fixed together.
Described pilot hole 200 is divided into the circle segments 210 and a non-circular section 220 of corresponding affixed section 120 of a corresponding thread segment 110.Described non-circular section 220 is common hex slot section or Flos Mume hex slot section.
The operating procedure of described locking nail can adopt following steps:
1, user should read over " orthopaedics internal fixation " and other related datas that AO organizational technology is recommended before using this product, and the skillfully operating process of this product;
2, select suitable position and operative approach according to fracture site, the exposure fracture site also resets, and selects the titanium material lockplate of appropriate length to be positioned over fracture site according to fracture situation, and guide pin is pierced the lockplate screw, be screwed into hollow locking nail along guide pin, postoperative is handled routinely.
The above, it only is this utility model preferred embodiment, so can not limit the scope that this utility model is implemented according to this, i.e. the equivalence of doing according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model contains.
