In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.Many details are explained in the following description in order to fully understand this hair
It is bright.
The present invention relates to a kind of preparation methods of orthopaedics implant.For example, the preparation method of the orthopaedics implant includes
Following steps: tubular screw is formed by extrusion process, the tubular screw includes the top and bottom being oppositely arranged.For example,
The top perimeter is formed with tapered thread section, and the bottom is formed with screw thread tip；And curved fastening top cover is consolidated
Due to the top of the tubular screw, to form orthopaedics pedicle screw.
Referring to Fig. 1, a kind of preparation method of orthopaedics implant, comprising the following steps: form tubular by extrusion process
Screw 20, the tubular screw include the top and bottom being oppositely arranged, and the top perimeter is formed with tapered thread section 21, institute
It states bottom and is formed with screw thread tip 23；And curved fastening top cover 30 is fixed on to the top of the tubular screw, with shape
At orthopaedics pedicle screw 100.
For example, the merging screw of orthopaedics made of the preparation method of the orthopaedics implant has arc top cover and tubular spiral shell
Nail, in use, the fastening top cover is fixed on the tubular screw, then pierces the tubular screw in bone, institute
The fastening top cover for stating arc can coincide the appearance of bone, improve the fixed effect to bone, and due to the tubular spiral shell
The top perimeter of nail is formed with tapered thread section, therefore can use the tapered thread section and reinforce interlocking to bone,
So that the orthopaedics merging screw is not easy to loosen from bone.
For example, the fastening top cover is ellipse for the ease of the fastening top cover to be fixed on the tubular screw
Sheet body opens up perforating 31 in the middle part of the fastening top cover, threaded hole 26, the screw thread is offered at the top of the tubular screw
Hole is corresponding with the perforating to be communicated.The orthopaedics pedicle screw further includes fastening nail 40, and the fastening nail is arranged in described wear
In apertured and it is screwed together in the threaded hole.The threaded hole is formed in the tapered thread section, the tapered thread section
Diameter is gradually reduced along the direction far from the fastening top cover.Holding channel is formed in the tubular screw, the accommodating is logical
The top in road is connected to the threaded hole.Since the orthopaedics pedicle screw further includes fastening nail, can use described tight
Gu the fastening top cover is fixed on the tubular screw by nail, and continues to screw the fastening and follow closely then rotate the cylinder
Shape screw, so that the tubular screw enters inside bone.
For example, for the ease of driving the tubular screw, the screw thread tip opens up that there are three conduction holes, and described three are drawn
Discharge orifice is arranged around the axis uniform intervals of the tubular screw.Three conduction holes are connected to the holding channel, institute
The diameter for stating conduction hole is less than the diameter of the holding channel.The fastening top cover is concavely provided with accommodation groove (not shown), described
Perforating is opened on the bottom surface of the accommodation groove.The accommodation groove is circular trough, and the diameter of the circular trough is greater than described wear
The diameter of apertured, the periphery of the accommodation groove are formed with driving slit.Straight tube thread segment is formed in the middle part of the tubular screw
25, the opposite end of the straight tube thread segment is separately connected the tapered thread section and the screw thread tip.Due to the fastening
Top cover is concavely provided with accommodation groove, and the periphery of the accommodation groove is formed with driving slit, therefore facilitates using described in the driving such as bottle opener
Top cover rotation is fastened, the tubular screw is finally driven to rotate again.
For example, it is of particular importance that for the ease of cleaning the orthopaedics pedicle screw of the ultrasonic scalpel, the orthopaedics
The preparation method of implantation material further includes cleaning the orthopaedics pedicle screw using wiper mechanism, and the wiper mechanism includes cleaning box
With inclination spray head, the cleaning box includes box body and the lid that is rotatably dispose on the box body, the bottom setting of the box body
There is supporting network, arc container is provided on the supporting network, the bottom of the supporting network is provided with multiple briquettings, the arc
Shape container is provided with bactericidal liquid storage body, the bactericidal liquid for accommodating the orthopaedics pedicle screw, the bottom of the box body
