In this way, the utility model discloses simple structure can restore ligament tendon stop, improves postoperative ligament intensity.
Description
Technical field
This utility model relates to a kind of improvement of cannulated compression screw, and particularly a kind of structure is simple, can repair, improve the band uropore cannulated compression screw of postoperative tough band strength to ligament tendon stop.
Background technology
Now general cannulated compression screw, comprises the head of a nail, rivet nut, nail tip, has through hole along its axial line, and its needle point is self tapping needle point.With Kirschner wire fixation, fix along Kirschner wire cannulated compression screw after the reduction of the fracture.Screw has pressurization to fracture, usually for tendon ligament stop position avulsion fracture, usually need during reduction of the fracture internal fixtion to peel off soft tissue, reduction of the fracture Ineffective internal fixation, usually cannot repair ligament tendon stop, or with remaining tissue apposition, postoperative tough band strength obviously declines.
Utility model content
It is simple that the technical problem that this utility model mainly solves is to provide a kind of structure, can repair, improve the band uropore cannulated compression screw of postoperative tough band strength to ligament tendon stop.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of band uropore cannulated compression screw, and comprising: screw body, described screw body comprises from top to bottom successively: the head of a nail, rivet nut and nail tip; Described screw body is provided with through hole along axial line; Described screw body upper end is provided with hole slot; Described hole slot lower end communicates with through hole; Described rivet nut bottom outer wall and nail tip outer wall are provided with screw thread; The screw thread of described nail tip outer wall is provided with self tapping groove; The outer wall of the described head of a nail is provided with through wires hole, through hole slot in the middle part of described through wires hole; The import of described through wires hole and outlet are all on head of a nail outer wall; The import of described through wires hole and the upper end of outlet are all vertically provided with wire casing; Described wire casing upper end is communicated with head of a nail upper surface, and lower end is communicated with through wires hole.
Preferably, described hole slot is interior hexangle type.
The beneficial effects of the utility model are: one band uropore cannulated compression screw described in the utility model; Structure is simple, can repair, improve postoperative tough band strength to ligament tendon stop.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 to Fig. 4, this utility model embodiment comprises:
A kind of band uropore cannulated compression screw, comprising: screw body 1, described screw body 1 comprises from top to bottom successively: the head of a nail 2, rivet nut 3 and nail tip 4; Described screw body 1 is provided with through hole 5 along axial line; Described screw body 1 upper end is provided with hole slot 6; Described hole slot 6 is in interior hexangle type; Described hole slot 6 lower end communicates with through hole 5; Described rivet nut 3 bottom outer wall and nail tip outer wall are provided with screw thread 7; The screw thread 7 of described nail tip 4 outer wall is provided with self tapping groove 8; Described self tapping groove 8 can effective dispersive stress, prevents bone from considering to be worth doing; The outer wall of the described head of a nail 2 is provided with through wires hole 9, through hole slot 6 in the middle part of described through wires hole 9; The import of described through wires hole 9 and outlet are all on the head of a nail 2 outer wall; The import of described through wires hole 9 and the upper end of outlet are all vertically provided with wire casing 10; Described wire casing 10 upper end is communicated with the head of a nail 2 upper surface, and lower end is communicated with through wires hole 9.
During operation, screw body 1 is fixed on bone, the import of suture from through wires hole 9 is penetrated, after hole slot 6, then pass from the outlet of through wires hole 9; , the two ends of suture are embedded respectively in the wire casing 10 be connected with the outlet of through wires hole 6 with the import of through wires hole 6 meanwhile, then by the two ends of suture through tendon ligament, and tie a knot in the upper end of tendon ligament; For sewing up fixing tendon ligament, rebuild tendon ligament stop.
The beneficial effects of the utility model are: one band uropore cannulated compression screw described in the utility model; Structure is simple, can repair, improve postoperative tough band strength to ligament tendon stop.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within this utility model rights protection scope.
