In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of medicolegal autopsy is cut with oblongata, comprise that oblongata haircut portion and oblongata cuts handle portion, described oblongata haircut portion and oblongata are cut between handle portion and are also provided with for regulating oblongata to cut the governor motion of head length and radian, and described oblongata haircut portion and oblongata are cut handle portion and is also provided with the retaining mechanism of cutting head position for fixing described oblongata.
According to a preferred embodiment of the present utility model: described governor motion comprises the arc extension of being located at oblongata haircut portion one end, be located at oblongata and cut the arc chute in handle portion, described arc extension can slide to regulate along arc chute the length of oblongata haircut portion.
According to a preferred embodiment of the present utility model: described retaining mechanism comprises to be located at a plurality of locking grooves of arc extension lateral surface and to be located at oblongata and to cut a plurality of rotational lock parts in handle portion, described rotational lock parts cooperatively interact with locking groove.
According to a preferred embodiment of the present utility model: described locking groove is dome-type locking groove, the ball-type protuberance of the bottom of described rotational lock parts for cooperatively interacting with dome-type locking groove.
According to a preferred embodiment of the present utility model: also comprise for making oblongata haircut portion return to the elastic return mechanism in home position.
According to a preferred embodiment of the present utility model: described elastic return mechanism comprises the groove of the end of being located at arc extension, is located at the spring in arc chute, and one end of described spring is connected with the bottom of groove, and its other end is connected with the bottom of arc chute.
Compared with prior art, the beneficial effects of the utility model are: this utility model regulates length and the radian of oblongata haircut portion by governor motion, after putting in place, adjusting adopt retaining mechanism by the position locking of oblongata haircut portion, make oblongata cut can be smooth the cross-section oblongata that gos deep into, and can be applicable to different dissection occasions, increase its versatility.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Description of reference numerals: 1, oblongata haircut portion, 2, oblongata cuts handle portion, 3, rotational lock parts, 4, locking groove, 5, groove, 6, spring, 7, arc chute, 8, arc extension.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult shown in Fig. 1 and Fig. 2, the present embodiment provides a kind of medicolegal autopsy to cut with oblongata, comprise that oblongata haircut portion 1 and oblongata cuts handle portion 2, described oblongata haircut portion 1 and oblongata are cut between handle portion 2 and are also provided with for regulating the governor motion of oblongata haircut portion 1 length, and described oblongata haircut portion 1 cuts handle portion 2 with oblongata and is also provided with the retaining mechanism for fixing described oblongata haircut portion 1 position.
The principle that the medicolegal autopsy of the present embodiment is cut with oblongata is: the length and the radian that by governor motion, regulate oblongata haircut portion 1, after putting in place, adjusting adopt retaining mechanism by the position locking of oblongata haircut portion 1, make whole oblongata cut can be smooth the cross-section oblongata that gos deep into, and can be applicable to different dissection occasions, increase its versatility.Meanwhile, the oblongata of the present embodiment is cut the integrity that has also guaranteed that brain is dissected, and has avoided the too short or common shears of crosscut oblongata to do one's utmost the risk of the damage normal cerebral tissue structure that test spinal cavity brings.
