Abstract
The utility model relates to the technical field of medical equipment, specifically a neck intervertebral disc locator, location main shaft and location syringe needle including interconnect, axis and the axis of location syringe needle of location main shaft lie in same straight line, should fix a position and be close to location syringe needle department on the main shaft and be equipped with the dark piece of the orbed limit of ban tuo, the dark piece of limit includes the planar structure of orientation location syringe needle side and the ARC structure of orientation location main shaft side, planar structure and location syringe needle mutually perpendicular. The beneficial effects of the utility model are that, reduce operation time, need not be used for inserting the syringe needle in intervertebral crack specially in preparation before the art at every turn, and the length of inserting the location syringe needle in intervertebral crack can obtain control, avoid the damage of doctor source nature.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of cervical intervertebral disk localizer.
Background technology
Cervical spondylosis is the common disease of serious harm human health.Anterior cervical operation is the most frequently used operative approach.In art, the location in cervical vertebra stage is the main method ensureing that operative site is correct.
At present, the normal length syringe needle of 20ml intercepted for 1cm clinically, clamped with kirschner pincers and inserted intervertebral space again, its shortcoming is at every turn the preoperative syringe needle that all again will prepare to be constructed for inserting intervertebral space, take time and effort, and the required precision making needle length is high, once the length of syringe needle is long, will cause spinal cord iatrogenic injury, the damage that also can cause for example operative site esophagus and trunk deviate from by syringe needle.
At present, be badly in need of a kind of can avoid iatrogenic injury and reduce operation preparation time, for carrying out the cervical intervertebral disk localizer of cervical vertebral space location before cervical intervertebral disk operation technique.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to avoid iatrogenic injury, and reduce operation preparation time, for carrying out the cervical intervertebral disk localizer of cervical vertebral space location before cervical intervertebral disk operation technique.
In order to achieve the above object, this utility model provides a kind of cervical intervertebral disk localizer, comprise interconnective positioning spindle and location syringe needle, the axis of described positioning spindle and the axis of location syringe needle are located along the same line, this positioning spindle is provided with the depth stop block of semielliptical shape near syringe needle place, location, described depth stop block comprises towards the location planar structure of syringe needle side and the globoidal structure towards positioning spindle side, and described planar structure is mutually vertical with location syringe needle.The depth capacity that described depth stop block is used for inserting cervical intervertebral disk localizer cervical vertebral space is carried out spacing, this depth stop block form is similar to the semielliptical shape of sub warhead.Described location syringe needle is inserted in the intervertebral space of cervical vertebra, described depth stop block also stretches in body, when the planar structure of depth stop block and vertebral surfaces are fitted, namely represents that location syringe needle has been inserted into limited depth capacity, meanwhile, the planar design of depth stop block adds the stability of this localizer.
Preferably, the lateral wall of described positioning spindle is provided with anti-skidding lines.
Preferably, described positioning spindle is hollow-core construction.Described hollow-core construction is for alleviating the own wt of cervical intervertebral disk localizer.
Preferably, the length of described location syringe needle is 6-12mm, and diameter is 1mm;
The length of described positioning spindle is 60-100mm, and external diameter is 3-6mm.
Preferably, the radius of described depth stop block is 3-4mm.
Further, the length of described location syringe needle is 10mm, and diameter is 1mm;
The length of described positioning spindle is 100mm, and external diameter is 5mm;
The radius of described depth stop block midplane structure is 3.5mm.
The beneficial effects of the utility model are, reduce operation preparation time, do not need the syringe needle being used for inserting intervertebral space in each preoperative making specially, and the length inserting the location syringe needle of intervertebral space can be controlled, and avoids iatrogenic injury.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1:
A kind of cervical intervertebral disk localizer as shown in Figure 1, comprise interconnective positioning spindle 1 and location syringe needle 2, the axis of described positioning spindle 1 and the axis of location syringe needle 2 are located along the same line, this positioning spindle 1 is provided with the depth stop block 3 of semielliptical shape near syringe needle 2 place, location, described depth stop block 3 comprises towards the location planar structure 31 of syringe needle 2 side and the globoidal structure 32 towards positioning spindle 1 side, and described planar structure 31 is mutually vertical with location syringe needle 2.The depth capacity that described depth stop block 3 is used for inserting cervical intervertebral disk localizer cervical vertebral space is carried out spacing, and this depth stop block 3 can be the semielliptical shape being similar to sub warhead.Described location syringe needle 2 is inserted in vertebra, described depth stop block 3 also stretches in body, when the planar structure 31 of depth stop block 3 is fitted with vertebral surfaces, namely represents that location syringe needle 2 has been inserted into limited depth capacity, meanwhile, the structural design of depth stop block 3 adds the stability of this localizer.
Preferably, the lateral wall of described positioning spindle 1 is provided with anti-skidding lines 4.
Preferably, described positioning spindle 1 is hollow-core construction.Described hollow-core construction is for alleviating the own wt of cervical intervertebral disk localizer.
The length of described location syringe needle 2 is 10mm, and diameter is 1mm;
The length of described positioning spindle 1 is 100mm, and external diameter is 5mm;
The radius of described depth stop block 3 midplane structure 31 is 3.5mm.
Below the preferred embodiment that this utility model is created is illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
