Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of hollow intramedullary nail.
Background technology
In fracture cures surgical operation, a good biocompatibility, strong is built into the pulp cavity proximally and distally of knochenbruch
Spend high inner matter --- intramedullary nail.The connection of fracture end and fixed purpose can not only be reached, but also patient can exempt
Outer fixed hardship can carry out functional training, therefore intramedullary nail is widely used in clinical practice in medical early stage.
Now commonly used intramedullary nail as shown in Figs. 1-2, including rivet nut 1 ', through-hole 11 ' is provided in rivet nut 1 ', described
Through-hole 11 ' extends along the central axis of rivet nut 1 ', and the proximal end of the rivet nut 1 ' is provided with the first locking nail hole 12 ', the rivet nut 1 '
Distal end be provided with the second locking nail hole 13 ', first locking nail hole 12 ' and the second locking nail hole 13 ' are identical with through-hole 11 '.
The intramedullary nail of above structure, although being conveniently first implanted into thin long guide pin before intramedullary nail implantation (compares intramedullary nail, carefully
Long guide pin more easily pass breaking part, penetrate through entire pulp cavity), then intramedullary nail fills in bone by through-hole along this long guide pin
It is interior.But intramedullary nail implantation after, especially intramedullary nail for treat neck of femur, tibial plateau either humerus head rupture,
Fragmentation needs first to stamp pinning in the first locking nail hole 12 ' of intramedullary nail proximal end when symptoms, so, the through-hole of perforation
11 ' proximal end is blocked by pinning, carries the length of illuminator with magnetic long guide pin or head if you need to be placed in intramedullary nail
Guide pin carrys out accessory external tool and carries out distal end aiming, can not just realize.
Invention content
It is unfavorable for distally aiming in order to which the through-hole for solving the problem of intramedullary nail in the prior art is blocked, this hair
It is bright to propose a kind of hollow intramedullary needle, solve above-mentioned technical problem.Technical scheme is as follows：
A kind of hollow intramedullary nail including rivet nut, is provided with through-hole in the rivet nut, the proximal end of the rivet nut is provided with first
Locking nail hole, the through-hole are extended to the distal end of rivet nut by the proximal end of the rivet nut, and the through-hole is relative to first locking nail hole
Biasing setting.
Further, the through-hole includes the offset segment, linkage section and the extended segment that are sequentially communicated along rivet nut proximal end to distal end,
The offset segment is biased relative to first locking nail hole and is set.
Further, axis of first locking nail hole Jing Guo the rivet nut, the offset segment is is opened in the rivet nut
U-type groove on outer circumference surface.
Further, the offset segment is extended to from rivet nut proximal tips at the 1/3 of rivet nut length, first locking nail hole
Positioned at rivet nut position corresponding with offset segment.
Further, the extended segment is set along the axis direction of rivet nut, and the linkage section connects the offset segment and institute
State extended segment.
Further, the distal end of the rivet nut is provided with the second locking nail hole.
Further, axis of second locking nail hole Jing Guo the rivet nut.
Further, first locking nail hole and second locking nail hole equal at least two.
Based on above-mentioned technical proposal, the technique effect achieved by the present invention is：The hollow intramedullary nail structure letter of the present invention
It is single, it can not only realize before intramedullary nail implantation, first be implanted into thin long guide pin, then intramedullary nail is filled in by through-hole along long guide pin
In bone, and after intramedullary nail implantation and in the case that pinning is stamped in proximal end, remain able to place with magnetic in through-hole
Property long guide pin or head carry illuminator long guide pin, accessory external tool carry out distal end aiming.In addition, the sky of the present invention
The extended segment of heart intramedullary nail still extends along the central axis of rivet nut, and after such guide pin is inserted into, the direction of end does not have deviation,
It is convenient accurately and efficiently to carry out distal end aiming.

Specific embodiment
Present disclosure is further described with reference to the accompanying drawings of the specification.
As in Figure 3-5, present embodiment discloses a kind of hollow intramedullary nails, including rivet nut 1, are provided in the rivet nut 1
Through-hole 11, the proximal end of the rivet nut 1 are provided with the first locking nail hole 12, and the distal end of the rivet nut 1 is provided with the second locking nail hole 13.
First locking nail hole 12 and second locking nail hole 13 pass through the axis of the needle body 1, first pinning
Hole 12 and second locking nail hole 13 equal at least two, preferably 2-5.First locking nail hole 12 and second pinning
Hole 13 is used to place pinning, plays fixed function.
The through-hole 11 is penetrated through by the proximal end of rivet nut 1 to the distal end of rivet nut 1, in order to avoid the first pinning of 1 proximal end of rivet nut
Pinning in hole 12 blocks the through-hole 11, and the through-hole 11 is biased relative to first locking nail hole 12 and set.Specifically, institute
It states through-hole to include along 1 proximal end of rivet nut to the offset segment A, linkage section B and extended segment C being distally sequentially communicated, the offset segment A is opposite
It biases and sets in first locking nail hole 12.The axis of extended segment C along the rivet nut 1 extends to the distal end of rivet nut 1, the connection
Section B connections offset segment A and extended segment C.
Preferably, the offset segment A is the U-type groove being opened on the rivet nut outer circumference surface, and the offset segment A and institute
It states and is not communicated between the first locking nail hole 12.
Preferably, the proximal tips of offset segment A from the rivet nut 1 are extended at the 1/3 of 1 length of rivet nut, first lock
Nail hole 12 is located at the position corresponding with offset segment A of rivet nut 1.
Using the intramedullary nail treatment neck of femur of the application, tibial plateau either humerus head rupture, fragmentation when symptoms, marrow
Before interior nail implantation, thin long guide pin is first implanted into, then intramedullary nail is filled in along this long guide pin in bone by through-hole 11；Intramedullary nail
After implantation, first the first locking nail hole 12 in the proximal end of rivet nut 1 is built into pinning, if you need to carry out intra medullary nail far-end using external tool
It aims at, then the long guide pin that illuminator is carried with magnetic long guide pin or head, the through-hole of perforation can be placed in through-hole 11
11 will not be blocked by the pinning in the first locking nail hole 12.
A kind of hollow intramedullary nail of the present invention is simple in structure, highly effective, convenient for multi-functional operation.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode, within the knowledge of a person skilled in the art, can also be in the premise for not departing from spirit of the invention
Under make a variety of changes.
