捅创论(附尸检例报告) 总被引:1,自引:1,他引:0
无尖无刃的细长钝器,沿其长轴戳入人体形成的创伤应命名为捅创。国内外现有的法医学书籍很少甚至没有描述过此创,个别作者将其归入锐器刺创。本文作者通过案例研究发现:不仅该创的致伤物为无刃无尖的棍棒类钝器(如木棍、木桩、手杖、擀面棍、铁锹把、竹竿、筷子、钢筋)而且成伤机制、形态学变化也与锐器刺创不同,应属于钝器伤。 相似文献

In a retrospective evaluation of 799 consecutive autopsies of victims of sharp force performed between 1967 and 1996 in Münster and Berlin, only 18 cases (2.3%) were classified as accidents. A typical pattern was present in 15 cases: inebriated adults (1.4-3.6g/l BAC) fell into an architectural glass surface in the form of a door or window (12 cases), an aquarium, a mirrored wardrobe or a telephone cell. Another man fell into a large drinking glass. Many victims in this group showed multiple scratches, abrasions and superficial incisions as well as one or more deep tear/cut/puncture injury. The wound margins can be clean-cut or irregular and abraded. Death was mostly caused by exsanguination except for one case of air embolism and one case of cerebral injury. The fatal injuries were produced by large and dagger-like slivers of glass, by sharp-edged fragments of glass remaining inside the frame or by a portion of glass which fell down and acted in a way similar to a guillotine. Ordinary types of flat glass were involved in all cases and it is not until the impact that sharp fragments or cutting edges are produced. So the motion of the person commonly provides the force necessary for a fatal injury. This was also true for the remaining two cases not involving architectural glass. A farmer suffered cerebral injury from a fall into the long prong of a pitch fork, and the wounding agent was a knife in only one case. A man who stated that he had fallen into the knife in his hand died from pneumonia after inadequate therapy following a single stab injury to the periphery of the left lung and liver. Accidents where the victim is killed by his own knife therefore appear to be extremely rare. 相似文献

During the course of a criminal trial, an investigating pathologist is commonly asked how much force was required to produce an injury. This subjective opinion is based on the pathologist's previous experience of dealing with wounds inflicted with similar weapons. However, in the case of stab wounds inflicted by broken glass, it is unlikely that two glass fragments would be physically similar. In the case studied, two theories were examined: that a wound resulted from a thrown glass fragment or that it had been caused as a stab injury by the glass held in the bare hand. The investigation involved quantifying the energy required for human tissue penetration, comparison of sharpness, a biomechanical analysis of throwing actions and testing of the hypothesis that if the glass shard were used as a stabbing implement it would result in a cut to the hand.The investigation utilised a scientific methodology that reduced the need for speculative (though informed) opinion from the pathologist by producing quantitative results. 相似文献

A comparative study of 174 homicidal and 105 suicidal sharp force deaths in the Stockholm area is presented in order to identify variables of importance in the differentiation between homicides and suicides. In homicides, a significantly (p<0.05) higher number of cut and stab wounds were seen in the head, upper and lower extremities and a significantly higher number of vertical stab wounds were found in the chest. Lower numbers were seen in the wrist and the crook of the arm. When counting the injured areas, irrespective of the number of injuries, abdominal wounds and horizontal chest stab wounds were also significantly more often found in victims of homicide. Injuries to the back and to the genitals were not seen in suicides. The suicide victims were significantly older and had significantly lower blood alcohol levels. A new variable pointing at a statistically significant difference between homicides and suicides was found: In homicides, stab wounds with a horizontal axis of entrance wound in the chest was found to be less common than those with a vertical axis. Other variables studied were prevalence of defence and tentative wounds, farewell notes and suicidal ideation, earlier parasuicides, venue, gender of the victims and the types of sharp objects used. 相似文献

We reviewed the case records of all fatalities due to sharp injuries in New York City in 1999. The epidemiological profile, circumstances, toxicology results, location, and injuries were examined. There were 120 deaths: 101 homicides, 17 suicides, and 2 accidents. The causes of death included: 112 due to stab(s) with or without incised wounds and 8 pure incised wound fatalities of which 5 were suicides. The detection of ethanol and/or illicit drugs was 61% in the homicide and 12% in the suicide groups. "Defense wounds" were reported in 49% of the homicides and "hesitation" wounds were found in 65% of the suicides. There were no self-inflicted sharp injuries of the face. Deaths due to a single stab wound occurred in 34% (34/101) of the homicides and 24% (4/17) of the suicides. Of these 38 deaths, 58% were of the anterior thorax (chest) and 71% injured the heart and/or great vessels. The remaining deaths with single stab wounds involved the femoral artery, abdominal organs, or head. There were no sharp injury suicides by Hispanics, Asians, or anyone under the age of 18 years. Over half of the suicides at home occurred in the bathroom and 78% of these occurred in the bathtub. Suicide notes were found in 24% of suicides, and an additional 24% verbally expressed a plan to commit suicide. 相似文献

At a party of a sports club, an argument started between two groups of young men, in the course of which one of the persons involved threw a beer glass hitting a young man of the other group, who collapsed with a profusely bleeding wound. Although resuscitation measures were initiated immediately, the victim died at the scene due to exsanguination from the completely severed left external carotid artery in combination with the aspiration of blood. Tests with drinking glasses thrown at a skull-neck model suggested that an undamaged beer glass thrown at the head of the victim could not cause the fatal injuries on the neck because of its splintering behaviour. In fact, it seemed that the beer glass had been damaged prior to throwing it and that its sharp edges perforated the skin on hitting the neck. 相似文献

Three cases are presented where fatal puncture wounds caused by broken glass were very similar to stab wounds inflicted by a knife with a single-edged blade. Thus, all three cases caused a murder investigation to be initiated. It could only be determined that these wounds had been caused by glass after a detailed forensic autopsy. In two of the three cases, the only evidence for this was the identification of glass fragments in the wounds. The importance of X-ray examinations is underlined because modern glass in common use is radiopaque. Glass fragments lodged in the wounds can reduce the loss of blood and thus, prolong the capacity to act despite severe injuries. 相似文献

Schizophrenia is associated with a significant risk of suicide. According to recent research, 10-15 % of all schizophrenic patients die by suicide. It is not uncommon that the victims show sharp force injuries, so that the forensic pathologist first has to differentiate between self-infliction and involvement of another person. The authors' case report presents a 68-year-old schizophrenic patient who committed suicide by jumping out of a window of his apartment located on the second floor after inflicting multiple stab wounds to his thoracic region. At autopsy, an older stab wound to the apex of the heart was detected. In the criminal investigation, a suicide attempt made 13 days before could be ascertained. As the patient did not want to be taken to a hospital at that time, the injury had never been examined or documented. Since there was no evidence suggesting homicide, the older stab to the heart was interpreted as a tentative injury. 相似文献

Stab wounds upon bone are analyzed to interpret the weapon used and the physical context in which the attack occurred. The literature demonstrates that most research conducted pertaining to wound patterns has been carried out on defleshed and unclothed bone samples, not adequately replicating actual circumstances. For this research, six half pig torsos (Sus scrofa), fleshed (including muscle, fat, epidermis, and dermis layers) and clothed, were stabbed using three knife types, applying both straight and downward thrusts. Analysis conducted macroscopically and through a scanning electron microscope with an environmental secondary electron detector revealed a general lack of consistency in wound pattern and associated secondary effects. Consequently, it was not possible to establish wound pattern per knife type as suggested in previous research or relate it to stab motion. Advantage of microscopic analysis was evident in recognizing wound traits and observation of trace evidence not visible macroscopically. 相似文献
