Abstract
INSTRUMENT FOR LIGATING BONE TISSUES OF RIBS
AND CLAVICLES WITH METAL STAPLES
ABSTRACT OF THE DISCLOSURE
An instrument for ligating bone tissues of ribs and clavicles with metal staple comprises an anvil body ri-gidly connected to a staple driving body which aacommodat-ed a staple pusher. The latter is mounted for reciproca-tion in relation to the anvil body. A hook with an anvil is mounted on the staple driving body for reciprocation in relation to the latter. The staple pusher and the hook are driven by kinematic pairs composed of a nut and a screw, as well as cams which translate longitudinal moti-on of the screws in relation to the anvil body into trans-verse motion of the staple pusher and the hook relative to the anvil body.

ABSTRACT OF THE DISCLOSURE
An instrument for ligating bone tissues of ribs and clavicles with metal staple comprises an anvil body ri-gidly connected to a staple driving body which aacommodat-ed a staple pusher. The latter is mounted for reciproca-tion in relation to the anvil body. A hook with an anvil is mounted on the staple driving body for reciprocation in relation to the latter.

Description
~.Z~fi~91 Field of the Invented The present invention relates to medical equipment and is more specifically concerned with instruments for ligating bone tissues of ribs and clavicles with metal staples.
Background ox the Invention There is known an instrument for ligating bone its-sues, which comprise an anvil body, a hook with an anvil for bending the legs of staples, and a staple driving an-viol which accommodates a staple usher.
The hook is composed ox two parts one ox itch is coupled to the anvil body, while the other is reciprDc-actable transversely to the anvil body. The second part of the hook is driven by a kinematic pair mounted on the anvil body and composed of a nut and a squire.
The staple driving body is hollow. It accommodates staples and is installed in guides provided on the anvil body.
The staple driving body is reciprocated along the anvil bond by a kinematic pair composed of a nut and a screw staple driving body moves along the anvil body toward the anvil of the hook.
The staple pusher is provided with a drive for ~1.226 ~91 push toe staples out of the staple wrung body 80 that the legs of the staples pierce the bone tissue and are brought into engagement with hollows provided it the anvil. In doing so, they are bet and ligate bone tissues (cf. ERG Patent No 2,109,604 and US Patent No 3,822,818).
The instrument it question is tided for dealing with simple fractures of rib, clavicles, jaw, etc.
It cases of multiple fracture of ribs, the use oil this instrument for osteosy~thesls requires multiple it-visions of soft tissues of the thoracic wall in fracture Ed ares. this prolongs the operation and makes it tray-matte. In severe kiwi such operations may lead to ox-Tramiel serious consequeLoes. It dealing with rib free-lures in the spiral part of the thoracic cage, it is ye-Cicero to dissect the broadest muscle ox the back. The dissection results in total disability of that muscle and increase the total amount of blood lost during the opera-Shea.
Summary of the Inveutio~
It is a object of the present invention to provide an i~trume~t for ligating bone tissues in cases of mull triple fractures of one rib or fractures of several ribs from a single limited operative incision without further dissecting 30ft Tess.
The invention provides dun in9trumeLt for ligating bore tissues of ribs and clavicles with metal staples, comprising as anvil body which carries a staple driving ..

body accommodating a staple pusher mounted or respire-cation along the staple driving body, a Cook with an an-viol or bonding the legs of tupelos which it mounted or reciprocation in relation to toe anvil body, and kin em tic pairs composed of a nut and a screw for driving thy staple pusher and the hook, which is characterized, act cording to the invention, in that the staple driving boy dye is rigidly scoured to toe anvil body, and in that the staple pusher and the hook are arranged transversely to the anvil body and driven in that direction through cams which translate the longitudinal motion of the screw ox the kinematic pair in relation to the anvil body into transverse motion of the staple pusher and the hook in relation to the anvil body.
It is preferred that the staple pusher and the owe be arranged at an angle o tooth- anvil body. Such an arrangement is best prom the viewpoint of thin.
It it also preferred that-the staple pusher and the hook be coupled to the respective cams by means of slid-ens mounted on the cams and received in-recesses provided in the staple pusher and the hook. This manner of couple it the staple pusher and the hook to the-cams makes ire a long service life of the instrument.
The instrument according to the invention for it-grating bone tissues of ribs and-clavicles is relatively simple in design, jet it it highly effective, fur it makes it possible to ligate bone tissue in case ox multiple ~.Z26~91 fractures ox owe rib or fractures of many ribs from a single limited incision without - further dissecting ought--tissues. the instrument ox this invention is easy to ma-nectar and reliable in operation.
