Abstract

The invention discloses an internal fixation hollow needle for a patellar fracture. The internal fixation hollow needle comprises a hollow nail body, wherein a nail head is arranged at one end of the hollow nail body; a thread section is arranged at one end of the hollow nail body; grooves are formed in tube walls at two ends of the nail body along the axial direction; the internal fixation hollow needle is characterized in that the hollow nail body is composed of a plurality of segments of split nail bodies which are connected and matched with one another; the plurality of segments of split nail bodies are formed by threaded connection; particularly, the plurality of segments of split nail bodies are formed by inner thread connection sections and outer thread connection sections; and the inner thread connection sections and the outer thread connection sections are respectively arranged on two sides of every two segments at intervals. By virtue of a thread connection mode of a plurality of hollow nail bodies, the length of the hollow nail can be adjusted according to the dimensions of patella of different patients; and the hollow nail does not need to be specially customized, so that the cost is greatly reduced.

Description

A kind of Patella fracture internal fixation hollow pin
Technical field
The present invention relates to a kind of orthopedic medical device, particularly relate to a kind of Patella fracture internal fixation hollow pin.
Background technology
When performing the operation for Patella fracture at present, fracture site is connected and fixed by main internal fixation hollow pin, this locking pin is hollow, axial zone groove structure, be convenient to the fixing of metal wire, but the length of hollow needle is fixing, and the patella length of each patient is all different, so in order to adapt to different demand, can only take the method customized, seem like this and bother very much, cost is also along with increase.
Summary of the invention
The present invention is exactly for the problems referred to above, proposes a kind of Patella fracture internal fixation hollow pin, and this hollow needle need not for different patient's custom-made, and cost declines greatly.
For reaching above-mentioned technical purpose, present invention employs a kind of Patella fracture internal fixation hollow pin, comprise the hollow rivet nut that the head of a nail is established in an one end, thread segment is established in one end, described rivet nut two ends tube wall is equipped with a groove vertically, and described hollow rivet nut is made up of the split rivet nut that some sections are interconnected with one another cooperation.
As preferably, described some sections of split rivet nuts adopt the composition that is threaded, and are specially: each section of this some sections of splits nails is that left end establishes male threaded joint, right-hand member be provided with can and male threaded joint form the female threaded joint formation be connected.
The present invention takes several hollow rivet nuts to adopt the mode be threaded, and achieves hollow nail and can regulate different length along with the size of the patella of different patient, need not custom-made, thus is greatly reduced by cost.
Accompanying drawing explanation
Shown in Fig. 1 is cross-sectional view of the present invention;
Wherein, 1, the head of a nail; 2, thread segment; 3, hollow rivet nut; 4, split rivet nut; 5, male threaded joint; 6, female threaded joint.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
As shown in Figure 1, a kind of Patella fracture internal fixation hollow pin, comprise the hollow rivet nut 3 that the head of a nail 1 is established in an one end, thread segment 2 is established in one end, at hollow rivet nut 3 two ends, tube wall is equipped with a groove vertically, and hollow rivet nut is made up of the split rivet nut 4 that some sections are interconnected with one another cooperation.
In the present invention, some sections of split rivet nuts 4 adopt the composition that is threaded, and are specially: each section of this some sections of splits nails is that left end establishes male threaded joint 5, right-hand member is provided with energy and male threaded joint 5 forms the female threaded joint 6 be connected and forms.
In the present invention, some sections of split rivet nuts 4 adopt the composition that is threaded, and are specially: each section of this some sections of splits nails is that left end establishes female threaded joint 6, right-hand member is provided with energy and female threaded joint 6 forms the male threaded joint 5 be connected and forms.
In the present invention, some sections of split rivet nuts 4 adopt the composition that is threaded, and are specially: these some sections of splits nails for be every one section of both sides female threaded joint 6, every one section of both sides be can and female threaded joint 6 male threaded joint 5 that forms the cooperation that is threaded form (specifically seeing Fig. 1).In figure, arrow direction is the direction that each section of split rivet nut 4 is connected.
