Detailed description of the invention
In order to further illustrate this utility model, below in conjunction with embodiment, the two plug screw screw of Wicresoft that this utility model provides being described in detail, but they can not being interpreted as the restriction to this utility model protection domain.
As shown in Figure 1, the two plug screw screw of this utility model Wicresoft is connected with pitman 17.Wherein, the two plug screw screw of this utility model Wicresoft comprises interior plug screw 1, outer plug screw 2, extension arm adapter 3, briquetting 4 and hollow ball heads nail 5, the inner hollow of described extension arm adapter 3, described pitman 17 laterally runs through described extension arm adapter 3, described outer plug screw 2 is movably arranged on the inside of described extension arm adapter 3, described interior plug screw 1 is movably arranged on the inside of described outer plug screw 2, and described pitman 17 can be made to be fixed on described extension arm adapter 3; Described briquetting 4 is arranged on the inwall of described extension arm adapter 3, for described hollow ball heads nail 5 being fixed on the end of described extension arm adapter 3.
Hollow ball heads is followed closely by arranging briquetting the end being connected to described extension arm adapter by the two plug screw screw of this utility model Wicresoft, hollow ball heads is followed closely locked in range of activity; By arranging interior plug screw and outer plug screw, pitman is fixed on described extension arm adapter, make when carrying out pyramidal support pressurization, the phenomenon that can prevent Vertebral rotation and highly lose, guarantees the reliability of operation technique.
As shown in Figure 2, the bottom of described interior plug screw 1 has lobe 7, for card and described pitman 17.By plug screw 1 in described in the internal rotating of plug screw 2 outside, tighten the effect that interior plug screw 1 can reach final locked pitman 17, in addition, also can adjust as required card and degree.Wherein, by arranging described lobe, the relative motion drag of hollow ball heads nail and pitman can be increased, make to rotate drag around rod higher, the mechanics situation that rod is bending can be adapted to, form stable triangle mechanical structure.
The inside of described extension arm adapter 3 is provided with female thread 9, and by described female thread 9, described outer plug screw 2 is flexibly connected with extension arm adapter 3.The outer wall of described interior plug screw 1 is provided with external screw thread, described outer plug screw 2 is provided with the screwed hole mated with interior plug screw 1, for the ease of installing described interior plug screw 1 in the inside of described outer plug screw 2, the top of described interior plug screw 1 is provided with mounting groove 6 (as shown in Figures 2 and 3), makes described interior plug screw 1 in described outer plug screw 2 inner rotation for bearing external force.In the present embodiment, described mounting groove 6 is hexagonal flower groove, but not as limit, also can be set to interior hex slot or " ten " word groove etc.
As figure, described outer plug screw 2 offering at least one opening (as shown in Figure 4 and Figure 5), for bearing external force, outer plug screw 2 being rotated in extension arm adapter 3.In the present embodiment, be provided with three openings altogether, can interior plug screw 1 outside plug screw 2 internal rotating time, described outer plug screw 2 uniform force.
As shown in Figure 6 and Figure 7, the outer wall of described extension arm adapter 3 is symmetrically arranged with at least one pair of first locating slot 12, described briquetting 4 is provided with the second locating slot 14, described second locating slot 14 and the first locating slot 12 are coaxially arranged, for when being subject to external force and running through described first locating slot and 12 second locating slot 14, described hollow ball heads nail 5 is made to be fixed on the end of described extension arm adapter 3.
Wherein, the head of hollow ball heads nail 5 is spherical, is provided with six square grooves in head, and the rivet nut inside of hollow ball heads nail 5 is through hole, and outer wall is provided with screw thread, hollow ball heads nail 5 can be made locked in range of activity by briquetting 4.
In order to when performing the operation, the redundance of the described extension arm adapter 3 that can fracture, the outer wall of described extension arm adapter 3 and/or inwall offer groove, and described groove is arranged on the middle and upper part of described female thread 9.When the outer wall and inwall of described extension arm adapter 3 are opened be equipped with groove time, the groove on outer wall and the groove on inwall are coaxially arranged.As shown in Figure 6, the groove on outer wall is V-type groove 11, and the groove on inwall is U-type groove 10.
The end that described extension arm adapter 3 and hollow ball heads follow closely the one end be connected is the first spherical 13 (as shown in Figure 6), the end of described briquetting 4 is the second spherical 15 (as shown in Figure 7), and described first spherical 13 and the second spherical 15 coupling are arranged.
When carrying out two plug screw screw lock two step of Wicresoft and locking: the lobe of interior plug screw can not directly be exposed bottom outer plug screw.If expose more than 1mm that just can locked rivet nut and pitman simultaneously with regard to a step, effectively can not realize pyramidal support pressurization.
When operation technique, first tighten outer plug screw 2, now in plug screw 1 be in loosening state, briquetting 4 applies external force, make hollow ball heads follow closely 5 rivet nut can be locked in range of activity; Now, pitman 17 can also be movable vertically, tightens interior plug screw 1, lobe 7 blocked and on described pitman 17, by on locked for pitman 17 described extension arm adapter 3, thus the vertebral body when pyramidal support pressurizes can be avoided to occur the phenomenon rotating and highly lose.
The two plug screw bolt structure of this utility model Wicresoft is simple, and when can effectively avoid pyramidal support to pressurize, the phenomenon rotating and highly lose appears in vertebral body, to alleviate patient's operation easier and operating time, improves the efficiency of operation.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
