WOUND BALLISTICS - I EFFECTS OF PERMANENT AND TEMPORARY WOUND CAVITIES

Effects of low velocity pistol and high velocity rifle projectiles on simulated tissue was evaluated experimentally in order to determine the role of ballistic features of the bullet on severity and depth of the wound in Firearm Wounds made by bullets. It was observed that the 7.65 pistol projectile which was used in the experiment have created a permanent cavity with it mass and rifle projectile have created temporary cavities in different sizes in addition to permanent one. 10% gelatine and paraffin first time in literature was used as simulated tissue and both static and dynamic temporary cavities was shown by using guided bullet. By this study we have conclude that, in wounds resulted from high velocity projectiles, due to the blast effect of temporary cavities, additional injuries on tissues around the guide of bullet should be considered in choices of treatment.

YARA BALÝSTÝÐÝ -I KALICI VE GEÇÝCÝ YARA BOÞLUÐU (KAVÝTE) ETKÝLERÝ

Mermilerde oluþan Ateþli Silah Yaralanmalarýnda, mermiye ait balistik özelliklerin, yaranýn þiddet ve derinliði üzerine etkilerini araþtýrmak amacýyla, düþük hýzlý tabanca ve yüksek hýzlý piyade tüfeði mermilerinin, doku simulanlarý üzerine etkileri deneysel olarak deðerlendirildi. Çalýþmada kullanýlan 7.65 tabanca mermisinin, kütlesi ile kalýcý kavite oluþturduðu, tüfek mermilerinin ise kalýcý kaviteye ek olarak deðiþik boyutlarda geçici kaviteye neden olduklarý gözlendi. Doku simulanlarý olarak %10 jelatin ve literatürde ilk kez parafin blok ve izli mermi kullanýlarak, statik ve dinamik olarak geçici kaviteler gösterildi. Yapýlan çalýþma ile, yüksek hýzlý mermilerle oluþan yaralanmalarda, geçici kavitenin yaptýðý blast etki sonucu, mermi yolunun çevresindeki dokularda, tedavi seçeneklerinde düþünülmesi gereken ek yaralanmalarýn olabileceði sonucuna varýldý.
