In forensic routine examination cases, autopsy plays a very important role, and not only can accurately judge the cause of death and determine the nature of death, but also can perform individual identification, accurately infer the death time and analyze and infer the injury-causing substances and the action modes thereof, which provides scientific and effective evidence for the examination cases and reconnaissance cases to a great extent ("meaning of forensic anatomic rooms in forensic necropsy work", li Xilin, etc., chinese rural health, 2013). Forensic autopsy is generally divided into systematic dissection and partial dissection, wherein the systematic dissection generally refers to a conventional dissection mode, and requires opening a 'three cavities' which are cranial cavities, thoracic cavities and abdominal cavities, and taking pathological examination materials. The dissection is used as a supplement to the dissection of the system, and is generally performed on the partial area possibly damaged, such as perineum, spinal cord, lumbar back, buttocks, limbs, etc.

Necropsy, in addition to testing cadavers, tissue and organs, blood urine interstitial fluid, and the like are taken from the cadavers for subsequent slicing and specimen preparation, or other testing. Thus, the forensic dissection tools required for autopsy are varied, such as knives, scissors, forceps, saws, etc., and are more complex than the usual surgical tools, and the optical tools may include large organ knives, small organ knives, brain knives, rib knives, amputation knives, etc.

Various different forms of scalpels for existing purposes can be considered to fall into two categories: the first is a scalpel in which a thumb-operable slider protrudes through the side wall of the scalpel handle, and the second is a scalpel in which the slider protrudes through a slot in one edge, which may be considered the top edge of the scalpel handle. A scalpel of the type of the utility model of ter Lei Woer john miltonian (CN 1700888 a) having: a handle having a longitudinally extending cavity therein; a blade carrier in the chamber, the blade carrier being longitudinally movable relative to the handle between an operative position in which the blade carrier is exposed at the open end of the chamber for use, and a non-operative position in which the blade carrier is retracted within the chamber in the handle; and a manually operable slider associated with the blade carrier that passes through a slot in the handle wall at a handle edge, referred to herein as a top edge; the scalpel is characterized in that the handle is molded as a single piece and is molded with an integral bridge defining an annular open end of the cavity through which the blade carrier can be introduced into the cavity, and the slider is formed as a separate piece that snap-fits over the blade carrier after introduction through the open end of the cavity to form the blade carrier and slider assembly.
