Abstract
The utility model relates to a brain coordinate location ruler which is composed of a transverse ruler and a longitudinal ruler which are mutually vertical to be fastened together and can oppositely move. The longitudinal ruler is provided with a guiding groove along an axial direction. The transverse ruler is provided with a stabilizer bolt matched with the guiding groove on the longitudinal ruler. The longitudinal ruler and the transverse ruler are combined through the guiding groove and the stabilizer bolt. The utility model has the advantage that the position and the area of size of a pathologic change in a brain can be directly and accurately marked on a skull, which is convenient to an operative procedure.
Description
This utility model relates to a kind of medical apparatus and instruments, is a kind of brain coordinate setting chi that clinical neurosurgery is determined the intracerebral lesion position that is used for specifically.
Mostly existing cerebral lesion positioner is according to the CT scan image solid location to be carried out at the cerebral lesion position, after determining the pathological changes coordinate, reuse overlaps overhead framework positioner and marks lesion locations and zone, and accuracy is higher, but general structure is complicated, use loaded down with trivial details, need calculate a plurality of data and position, operation is wasted time and energy, simultaneously owing to be that positioning framework is enclosed within the enterprising line operate of head, also can influence the operation and the demonstration of operation of opening cranium, cost is higher in addition.
The purpose of this utility model provides a kind of brain coordinate setting chi simple in structure, easy to use, with low cost with regard to being to overcome present the deficiencies in the prior art part.
The purpose of this utility model can realize by following measure:
This utility model is to be made of the crossfoot and the linear foot that vertically snap together and can do relative displacement mutually.
Linear foot described in the utility model offers gathering sill vertically, and crossfoot is provided with the caging bolt that matches with gathering sill on the linear foot, and longitudinal and transverse two chis combine by gathering sill and caging bolt.One end of described linear foot is provided with the orientation angle card, also is provided with an orientation angle card in the crossfoot end at the longitudinal and transverse two chi places of being interlocked, and the tip of the orientation angle card of linear foot is concordant with the zero graduation line, and the tip of the orientation angle card of crossfoot is concordant with the same side of crossfoot.
The utility model has the advantages that can be intuitively, position, the size area with intracerebral lesion is labeled on the head exactly, is convenient to operation technique.
Accompanying drawing is a front view of the present utility model.
This utility model is done with detailed description below with reference to embodiment (accompanying drawing):
As shown in the figure, this utility model is to be made of crossfoot (1) that vertically snaps together and can do relative displacement mutually and linear foot (2), on linear foot (2), offer gathering sill (3) vertically, crossfoot (1) is provided with the caging bolt (4) that matches with gathering sill (3) on the linear foot (2), and longitudinal and transverse two chis (1) (2) combine by gathering sill (3) and caging bolt (4).Crossfoot (1) can slide arbitrarily along the gathering sill (3) of linear foot (2).One end of linear foot (2) is provided with orientation angle card (5), crossfoot (1) end at longitudinal and transverse two chis (1) (2) place of being interlocked also is provided with an orientation angle card (5), the tip of the orientation angle card of linear foot (2) is concordant with the zero graduation line, and the tip of the orientation angle card of crossfoot (1) is concordant with the same side of crossfoot (1).
This utility model in use, at first measure the lesion region size according to electron tomographies such as CT scanning sheet, calculate actual size in conjunction with scale again, can be more convenient when utilizing orientation angle card (5) to measure, after measurement is finished, linear foot (2) upper limb is fixed in (same branch hole/ear line) on the baseline, moves the horizontal vertical coordinate point that crossfoot (1) is determined pathological changes point according to measurement data, be labeled on the brainpan according to coordinate points each boundary point, can determine lesion region the pathological changes figure.
