Abstract
Abstract of the Disclosure The device for uniting bone fragments comprises a body and a means of its fixing in the coapted bone fragments, Said means of fixing the body in bone fragments is formed by thrust members which are in fact the portions of said body located at the opposite ends thereof and having holes coaxial with said body; said holes being shaped as frustums of cones facing with their greater bases the ends of the body, whereas the bore surfaces of said holes have annular grooves, and cone-shaped inserts having annular rides and adapted to be intro-duced into said holes so as to wedge apart said body. Said body has longitudinal through recesses located within the zo-nes of said holes. the device features its length less than a total length of the coapted bone fragments so as to be ar-ranged fully in the bone tissues.

~s particular rcfcrc~ec-to devices ~or uniting bone fra~;ments,.
v~
9~
The present invention relates to medical equipment and in particular to devices for uniting bone fragments, The present invention has preferable application for fixing the coapted bone fragments, such as those of the shin, arm, and forearm.
Known in the present state of the medical art are de-vices for uniting bone fragments in the shape of rods or pins made of diverse materials and adapted to be driven into the medullary canal by hammering (cf. "Intraosseous fixation with a metal rod in fractures of long tubular bones" by Ya.G.
Dubrov, ~5editsina Publishers, Moscow 1972), screwing in (cf.
"Orthopedics, traumatology and prosthetics" No. 8, 1971), or lS by fixing one of the rod ends in the medullar canal by means of thrust members (cf. USSR Inventor's Certificate No. ~19,003).
The known device o the character set forth hereinfore by Fisher and Muller protected by USSR Inventor's Certificate No. 419,003 comprises a sleeve-like body carrying at one end a thrust member and at the other end, a screw. The thrust member consists of shoulders and a thrust head, whereas the screw is adapted for retracting the thrust head and wedging the shoulder apart in the medullar canal, When operating the known device is introduced for its entire length into a preliminarily bored out medullary canal, whereupon the screw projecting beyond the bone tissue is ro-tated so as to retract the thrust head in the shoulders, thus wedging apart the thrust member.
.
The aforesaid known device provides for fixation of bone fragments for a period of their consolidation. However, the fixation process carried out by said device results in traumas inflicted UpQn the surrounding tissues and the bone end both X
~ ~9~
at the moment of fixation and within the consolidation pro ces3. r~oreover, an adequately wide range of the sleeve-like bodies must be at surgeon's disposition before the operationg both with respect to the diameter and length so as to suit the size of bone~ to be operated and location of a ~racture le~g-th-wise the bone.
In addition, ~mall con-tact area of the thrus~ member ~ith the medullary canal needs the provisio~ of a reasonabl~
high local pressure upon the walls o~ the medullary canal, which results in necrosis and weakened ~i~ation o~ the sleeve~
like body within the period of consolidation, Once the conso~
- lidatio~ o~ bo~e fragments has occurred a repeated surgical inter~ention is involved ~or removal of tke device for unit-ing bone fra~ments ~rom the bone operated uponO
It is an object of the present invention to provide ~
device for uniting bone fragments which would ensure a reliab-le ~ixation of bone ~ragments ~or an entire period of their consolidation.
It is ano~her object of the present invention to provide a device for uniting bone fragments ~hich would preclude any B injur~ to the exte~nal bone surface and the surrounding soft tissues and ~lould not impede re~eneration o~ bone marrow àust a~ter fixatio~ of bone fragments~
It is one more object of the present invention to pro-vide such a device for uniting bone fragments that would not in~olve its ma~ching as ~or le~gth and would dispense ~ith a~y repeated operation ~or extracting said device after con-solidation o~ bo~e fragments.
The present invention provides a device for uniting bone fragments, comprising a body and a means of its ~ixing in the coapted bone f.ragments, in which said means of fixing the body in the coapted bone fragments is formed by thrust members which are in fact the portions of the body located at the opposite ends thereof and having holes coaxial with the body and shaped as conical frustums with their larger bases facing the ends of said body, the surf~ces of said holes hav-ing annular grooves and cone-shaped inserts having annular ridges and adapted to be introduced into the holes so as to wedge apart the body which is provided with longitudinal through recesses located within the zones of said holes; the device having a length less than a total length of the coapted bone fragments so as to be arranged fully in the bone tissues.
Such a construction of the device for uniti.ng bone fragments provides for a reliable fixation of bone fragment throughout the period of their consolidation, precludes in-~ury to the bone surface and the surrounding soft tissues as having no parts protruding beyond the bones being handled, puts no obstacles in the way of regeneration of bone marrow within a greater portion of the medullary canal as the length - of the device is substantially less than that of the above canal, involves neither matching of the device as for length -. 25 in order to suit the localization of the fractured bone nor performing any repeated operation.
It is expedient that longitudinal s~ots be provided on the outside body surface which will favour regeneration of the ~1~9~35 bone marrow within the period of consolidation of bone fragments.
Given below is a detailed description o~ some illu-strative embodiments of the present invention given by way of example with reference to the accompanying drawings, wherein:
FIG. 1 illustrates a device for uniting bone fragments, according to the invention; and FIC-. 2 is a section taken along the line II-I~ in Fig. 1.
The device for uniting bone fragments comprises a body 1 (FIG. 1~ and a means of its fixing in the coapted bone fragments, said means being established by thrust members made as the portions of the body 1 located at the opposite ends thereof and provided with holes 2 coaxial with the body 1 and shaped as frustums of cones facing with their greater bases the ends of the body 1, the bore surfaces of said holes having an-nular grooves 3, whereas respective inserts 4 and 5 are pro-vided in the means in question. The inserts 4 and 5 are cone-shaped and are adapted to be introduced into the holes 2 so as to wedge apart the body 1 which is provided with longitu-dinal through recesses 6 located within the zones of the holes
