Abstract
The invention relates to a locked internal marrow nail, wherein its main body is hollow tube whose middle is arc matched with human long bone; two ends of tube both have at least two locking holes of locking nails; two sides of locking holes are covered by films. The tube has blind hole at the end that inserted into the long bone; the tube between bottom of said end and the nearest locking hole is mounted with positioning device. The invention has simple structure and operation.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the fixing interlocking intramedullary nail of using that the key fracture of the elongated tubular in especially a kind of orthopaedics therapy is used, specifically a kind of interlocking intramedullary nail that has positioned light source.
Background technology
Interlocking intramedullary nail has been widely used in treating the key fracture of elongated tubular because its good and clinical curative effect, and it has fixation, avoid fracturing axially and the generation of rotation deformity.But, interlocking intramedullary nail can deform because being subjected to the influence of key physiological feature when implanting the backbone, and because the existence of human body individual variation, deflection has nothing in common with each other, if therefore hole on the backbone according to conventional method, pinning usually can't correctly be aimed at the lockhole on the interlocking intramedullary nail nail body, so that can't fix, must reorientate boring, so not only prolonged operating time, and postoperative there is nail loose, moves back nail, the risk of complication such as increase postoperative infection chance.For this reason, vast orthopaedics worker is developing various external positioners and is overcoming the inaccurate problem of boring that causes because of the interlocking intramedullary nail distortion, wherein utilizing endoscope's optical imaging system accurately to locate is a kind of relatively one of scientific methods (seeing another patent application about positioner that the applicant applies on the same day for details), but lacks a kind of interlocking intramedullary nail that matches with it for using.
Summary of the invention
The objective of the invention is to lack a kind of interlocking intramedullary nail that has positioned light source of interlocking intramedullary nail design that matches at present optical positioning system.
Technical scheme of the present invention is:
A kind of interlocking intramedullary nail that has positioned light source, its main body is that a stage casing has with the human body long bone and (comprises femur, tibia, humerus etc., the tubular body of the hollow of the radian that matches down together), each is provided with two lockholes that install pinning at least on the two ends of this tubular body, all be coated with thin film on the both sides of lockhole, it is characterized in that the insertion end that described tubular body inserts the human body long bone is a blind hole structure, be equipped with to locate in the tubular body on the bottom of this end and this end between the nearest lockhole and use light-emitting device.
Described light-emitting device is the low-light light-emitting device, and it can be made up of light emitting diode and miniature button cell.
The profile of the blind hole end of described tubular body is the pyramidal structure of being convenient to insert, and is processed with female thread in the other end lockhole of tubular body.
Described tubular body is processed a female end and is provided with the radial location groove.
Beneficial effect of the present invention:
The invention solves market in urgent need,, use and easy to operate interlocking intramedullary nail for optical positioning system provides a kind of simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to view.
Fig. 4 is a user mode sketch map of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, 2, 3.
A kind of interlocking intramedullary nail that has positioned light source, its main body is that a stage casing has and the match rustless steel tubulose body 1 of hollow of radian of human body long bone, on the two ends of this tubular body 1, respectively be provided with two lockholes 2 that install pinning and (can be circular hole or long lumbar hole, or part is a circular hole, part is a long lumbar hole, every interlocking intramedullary nail of present embodiment is provided with three cylindrical holes, a long lumbar hole), all be coated with thin film 3 on the both sides of lockhole 2, the insertion end that described tubular body 1 inserts the human body long bone is the pyramidal structure of blind hole structure, as Fig. 1, shown in 2, the location is installed with light-emitting device 5 in the tubular body 1 on the bottom 4 of this end and this end between the nearest lockhole 2, this light-emitting device 5 be the main low-light light-emitting device of being made up of light emitting diode 6 and miniature button cell 7.The profile employing pyramidal structure of the blind hole end of tubular body 1 helps pinning of the present invention and conveniently advances to insert among the backbone, in the other end lockhole of tubular body 1, be processed with female thread 8 and the radial location groove of being convenient to link to each other, prevent its rotation 9, as shown in Figure 3 with positioner.
User mode of the present invention as shown in Figure 4.At first before not inserting the backbone, enter in the tubular body 1 during use by the endoscope that has CCD (digital camera head) (should adopt the endoscope of the rod shaped structure of the rigid structure) drive that links to each other with computer, by endoscope obtain light-emitting device 5 positional information and by eyepiece with its send into CCD in send in the computer system after converting the number that computer can discern to, then interlocking intramedullary nail of the present invention is hammered among the backbone, again aforesaid endoscope is stretched into the positional information that obtains light-emitting device 5 in the interlocking intramedullary nail of the present invention once more, because the insertion end of interlocking intramedullary nail of the present invention can deform, therefore the ccd image position of the light-emitting device that obtains of secondary will inevitably change, this moment can be by the publish picture displacement of picture of mathematical calculation, thereby determine the displacement of the lockhole 2 of close insertion end on the interlocking intramedullary nail of the present invention, again by will be on the positioner with the equidirectional mobile phase of reference mark post of the parallel installation of interlocking intramedullary nail of the present invention with amount can accurately determine the position of the lockhole 2 on the interlocking intramedullary nail insertion end, utilize medical drill bit on the backbone, can get out accurately pinning (being generally the medical stainless steel screw) and install and use lockhole.
Claims (4)
1, a kind of interlocking intramedullary nail that has positioned light source, its main body is that a stage casing has and the match tubular body of hollow of radian of human body long bone, each is provided with two lockholes that install pinning at least on the two ends of this tubular body, all be coated with thin film on the both sides of lockhole, it is characterized in that the insertion end that described tubular body inserts the human body long bone is a blind hole structure, be equipped with to locate in the tubular body on the bottom of this end and this end between the nearest lockhole and use light-emitting device.
2, the interlocking intramedullary nail that has positioned light source according to claim 1 is characterized in that described light-emitting device is the low-light light-emitting device, and it mainly is made up of light emitting diode and miniature button cell.
