Abstract
An optical locating method for the locking hole of intramedullary nail includes inserting the light conducting tube composed of optical fibre and coupled to light source in the internal cavity of said intramedullary nail, regulating the light condcuting tube to make its front end position at the locking hole, and determining the position of locking hole according to the light beam passing through the locking hole. Its advantages are high correctness and short operation time.
Description
Technical field:
The present invention relates to a kind of medical science orthopaedic trauma and in the treatment long tubular bone fracture, use locking of intramedullary nail light projection method and device thereof.
Background technology:
In the bone surgery of prior art; after known intramedullary pin penetrates in the pulp cavity; by locating sight behind the location drilling of otch sclerotin stomidium that undergos surgery; the stomidium that on sclerotin, gets out; particularly between the distal lockhole of remote stomidium and intramedullary pin through regular meeting occur in various degree aim at incomplete wrong hole phenomenon; brought certain obstacle for the lockhole that pinning penetrates on the intramedullary pin in the clinical operation; hindered finishing smoothly of clinical operation; prolonged operating time, brought very big misery to patient.
Summary of the invention:
The purpose of this invention is to provide a kind of when in bone surgery, using the synthetism of locking of intramedullary nail location to the locking of intramedullary nail localization method, to remedy the deficiencies in the prior art.
Locking of intramedullary nail light projection method of the present invention, carry out according to the following steps:
1. will link to each other with light source by the light guide that optical fibers is formed earlier;
2. light guide is inserted in the intramedullary pin inner chamber;
3. adjust the light guide front end according to known locking of intramedullary nail position and be positioned at the locking of intramedullary nail place;
4. the light that sends by light guide shows the accurate position of locking of intramedullary nail.
Locking of intramedullary nail light projection device of the present invention, it includes the intramedullary pin location sight that hanging bolt, coupling sleeve, handle, connection handwheel, support, drill bushing, guide rod lock wheel, guide rod etc. are formed, and it also includes the removable light guide of removable joint, shell, optical fibers composition; In the described shell optical fibers is housed, removable joint is housed at the end of removable light guide.
Locking of intramedullary nail light projection device of the present invention, the shell of described removable light guide is provided with scale.
The advantage of orthopaedics locking of intramedullary nail light projection method of the present invention and device thereof is: in the synthetism operative process, nontoxic, radiationless light guide is inserted the inner chamber of intramedullary pin, according to known locking of intramedullary nail position, by the scale on the removable light guide shell, removable light guide front end is inserted into the locking of intramedullary nail position, light shines from locking of intramedullary nail, the accurate position of indication locking of intramedullary nail, be very easy to operation technique, shorten the time of operation, alleviated the painful and dangerous of patient.
Description of drawings:
Fig. 1 is a working state schematic representation of the present invention.
Fig. 2 is the structural representation of removable optical fiber tube among the present invention.
Among the figure: 1 removable light guide, 2 hanging bolts, 3 coupling sleeves, 4 handles, 5 pins, 6 connect handwheel, 7 supports, 8 drill bushings, 9 guide rods lock wheel, 10 guide rods, 11 intramedullary pins, 12 removable joints, 13 optical fiberss, 14 scales, 15 shells.
The present invention will be further described below in conjunction with accompanying drawing.
The specific embodiment:
As shown in FIG., locking of intramedullary nail light projection method of the present invention is according to the following steps:
1. will link to each other with light source by the light guide that optical fibers is formed earlier;
2. light guide is inserted in the intramedullary pin inner chamber;
3. adjust the light guide front end according to known locking of intramedullary nail position and be positioned at the locking of intramedullary nail place;
4. the light that sends by light guide shows the accurate position of locking of intramedullary nail.
Locking of intramedullary nail light projection device of the present invention, it includes the intramedullary pin location sight that hanging bolt 2, coupling sleeve 3, handle 4, pin 5, connection handwheel 6, support 7, drill bushing 8, guide rod lock wheel 9, guide rod 10 etc. are formed, and it also includes the removable light guide 1 of removable joint 12, shell 15, optical fibers 13 compositions; In the described shell 15 optical fibers 13 is housed, removable joint 12 is housed at the end of removable light guide 1.
In the locking of intramedullary nail light projection device of the present invention, the shell 15 of described removable light guide 1 is provided with scale 14.
A kind of embodiment of orthopaedics locking of intramedullary nail light projection method of the present invention and device thereof, its light source send light source to removable optical fiber tube 1 from the light source generator of peripheral hardware by the optical fiber flexible pipe.
Orthopaedics locking of intramedullary nail light projection method of the present invention and device thereof are in the synthetism operative process, nontoxic, radiationless removable light guide is inserted the inner chamber of intramedullary pin, according to known locking of intramedullary nail position, by the scale 14 on removable light guide 1 shell 15, removable light guide 1 front end is inserted into intramedullary pin 11 lockhole positions, light shines from locking of intramedullary nail, the accurate position of indication locking of intramedullary nail, be very easy to operation technique, shorten the time of operation, alleviated the painful and dangerous of patient.
