Abstract
The utility model discloses a special opener for lock hole inlet on orbit, the front end of common opener is provided with two support mouth, wherein, the support mouth on the upper part of the cut takes the shape of an arc and consists of a support tooth which is an arc-shaped board. The support tooth is provided with holes, the support mouth at the lower part of the cut is a support board with hole and whose rear part is provided with a zygomatic process support tooth whose installing part is 30 to 40 mm away from the most front part of the support mouth. The zygomatic process support tooth is a curved projected object, the support mouth at the upper part of the zygomatic process support tooth and the support mouth at the lower part of the cut are connected with the handle of prior art. The arc-shaped support mouth matches the radian of the cut so as to make the upper skin of the cut evenly open and enlarge the support degree at the middle of the cut. The zygomatic process support tooth can abut the concave part of the zygomatic process so as to limit the lowering of the front part of the support mouth. Thus, the utility model can be prevented form pressing the eyepit.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of supraorbital foramen entrance opener that is exclusively used in neurosurgery " keyhole " operation.
Background technology:
Need strut otch when using supraorbital keyhole approach in the clinical treatment, main common mastoid process dilator of use or drag hook, silk thread tractive in the prior art.
Summary of the invention:
Technical problem to be solved in the utility model is: owing to need strut otch when using supraorbital keyhole approach in the clinical treatment now, main common mastoid process dilator or the drag hook of using in the prior art, the silk thread tractive, because the lower edge of geisoma otch is an eyelid, skin is thin and soft, and cutting shoulder skin is more tough, but when firmly strutting supraorbital keyhole approach, because the resistance inequality of two cutting edges of geisoma antagonism, the otch lower edge is passed more obvious than upper limb, causing supportting mouth glides, the socket of the eye top skin that really needs to expose is difficult to strut, the orbital contents of otch bottom is pressurized then, cause the crush injury of orbital contents probably, if, and when needs are removed the socket of the eye top, support mouth and still unavoidably can oppress the socket of the eye content with the support mouth of dilator support visual field of basis cranii then stopping again before on the socket of the eye top, and when adopting drag hook and silk thread, its tractive strength can not satisfy the needs that otch retracts exposure again.This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide the special-purpose dilator of a kind of supraorbital keyhole approach, the special-purpose dilator of described this supraorbital keyhole approach comprises the handle of a common dilator in the prior art, wherein, the front end of the handle of the common dilator in described prior art is provided with two support mouths, the support mouth that wherein is used in cutting shoulder is an arc, the described support mouth that is used in cutting shoulder comprises a support tooth, described support tooth is an arc, described support tooth is provided with the hole, the support mouth that is used in the otch lower edge is a fagging with holes, its rear portion is provided with a zygomatic process support tooth, described zygomatic process support tooth the position is set apart from support mouth forefront 30-40mm, described zygomatic process support tooth is a zigzag protrusion, and the described support mouth that is used in cutting shoulder is connected with described handle by the Movable joint in the prior art respectively with the support mouth that is used in the otch lower edge.This utility model and prior art contrast, the described arc support mouth that is used in cutting shoulder can adapt to the radian of otch, make cutting shoulder skin can evenly strut and increase the degree of strutting at otch middle part, the described support tooth of two support mouths up and down is provided with the hole, can reduce damage to facial tissue, the zygomatic process support teeth directional outside on the described support mouth that is used in the otch lower edge is outstanding, when pass otch lower edge skin downwards when just having appeared margo orbitalis support mouth front portion, zygomatic process support tooth can prop up depression behind the angular process of frontal bone,external, and mouth is forward further moves down with the restriction support, avoid oppressing eye socket, and make top skin continue to strut as support, finish the needs of exposure, Movable joint by described connection support mouth and handle can be dismantled the support mouth, convenient when the difference operation needs support replacement mouth more.
Description of drawings:
Fig. 1 is the sketch map of the special-purpose dilator of this utility model supraorbital keyhole approach.
Fig. 2 is the structural representation of the support mouth of the special-purpose dilator of this utility model supraorbital keyhole approach.
The specific embodiment:
As Fig. 1, shown in Figure 2, the special-purpose dilator of this utility model supraorbital keyhole approach, the handle 1 that comprises a common dilator in the prior art, wherein, the front end of the handle 1 of the common dilator in described prior art is provided with two support mouths, the support mouth 2 that wherein is used in cutting shoulder is arc, the described support mouth 2 that is used in cutting shoulder comprises a support tooth 3, described support tooth 3 is an arc, described support tooth 3 is provided with the hole, the support mouth 4 that is used in the otch lower edge is a fagging with holes, its rear portion is provided with a zygomatic process support tooth 5, described zygomatic process support tooth 5 the position is set apart from support mouth 4 forefront 30-40mm, described zygomatic process support tooth 5 is a zigzag protrusion, and the described support mouth 2 that is used in cutting shoulder is connected with described handle 1 by the Movable joint in the prior art 6 respectively with the support mouth 4 that is used in the otch lower edge.This utility model and prior art contrast, the described arc support mouth 2 that is used in cutting shoulder can adapt to the radian of otch, make cutting shoulder skin can evenly strut and increase the degree of strutting at otch middle part, the described support tooth of two support mouths up and down is provided with the hole, can reduce damage to facial tissue, zygomatic process support tooth 5 on the described support mouth 4 that is used in the otch lower edge is outstanding laterally, when pass otch lower edge skin downwards when just having appeared margo orbitalis support mouth 4 front portions, zygomatic process support tooth 5 can prop up depression behind the angular process of frontal bone,external, and mouth is forward further moves down with the restriction support, avoid oppressing eye socket, and make top skin continue to strut as support, finish the needs of exposure, Movable joint 6 by described connection support mouth and handle 1 can be dismantled the support mouth, convenient when the difference operation needs support replacement mouth more.
