Abstract
The utility model discloses a kind of spinal column intervertebral bone grafting apparatus, relate to field of medical device, comprise handle (1), inner core (2), guide channel (3), one end of inner core (2) is connected with handle (1), the other end of inner core (2) is positioned at guide channel (3), and the outer wall of guide channel (3) is provided with location resistance sheet (4).Described in the utility model is by guide channel lateral surface being arranged location resistance sheet, reaching the object of safe bone grafting with this; This utility model is practical, and structure is simple, and practicality is good, for the harassing and wrecking of spinal cord and dural sac minimum degree, reduces neural damage, reduces operation easier simultaneously, reduces operation time and hemorrhage.
Description
[technical field]
This utility model relates to field of medical device, especially relates to a kind of spinal column intervertebral bone grafting apparatus.
[background technology]
Known, spinal fusion surgery needs to merge in interbody bone graft and fusion device in art, because of the unrestricted degree of depth of existing bone grafting apparatus with without the design adding force in actual mechanical process, so easily occur that bone grafting instrument slides, thus cause the damage of spinal cord and nerve root, also easily occur that intervertebral bone graft is loose, the rare melting interface of bone amount is little in addition, thus cause the failure that bone grafting absorbs and merges.
[summary of the invention]
In order to overcome the deficiency in background technology, the purpose of this utility model is to provide that a kind of structure is simple, the spinal column intervertebral bone grafting apparatus of use safety.
In order to realize described goal of the invention, this utility model adopts following technical scheme:
A kind of spinal column intervertebral bone grafting apparatus, comprise handle, inner core, guide channel and location resistance sheet, one end of inner core is connected with handle, and the other end of inner core is positioned at guide channel, and the lateral wall of guide channel bottom is provided with location resistance sheet.
Described inner core is cylindrical structure.
Described guide channel is round tube shape structure, and the lateral wall of guide channel is at least provided with a location resistance sheet.
Owing to have employed technique scheme, this utility model has following beneficial effect:
Described in the utility model is by guide channel lateral surface being arranged location resistance sheet, reaching the object of safe bone grafting with this; This utility model is practical, and structure is simple, and practicality is good, for the harassing and wrecking of spinal cord and dural sac minimum degree, reduces neural damage, reduces operation easier simultaneously, reduces operation time and hemorrhage.
[accompanying drawing explanation]
Fig. 1 is perspective view of the present utility model;
In figure: 1, hands handle; 2, inner core; 3, guide channel; 4, location resistance sheet.
[detailed description of the invention]
By explanation this utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of this utility model.
A kind of spinal column intervertebral bone grafting apparatus by reference to the accompanying drawings described in 1, comprise handle 1, inner core 2, guide channel 3 and location resistance sheet 4, one end of inner core 2 is connected with handle 1, and the other end of inner core 2 is positioned at guide channel 3, and the lateral wall of guide channel 3 is provided with location resistance sheet 4; Described inner core 2 is cylindrical structure; Described guide channel 3 is round tube shape structure, and the lateral wall of guide channel 3 is at least provided with a location resistance sheet 4.
Implement a kind of spinal column intervertebral bone grafting apparatus described in the utility model, in use, first the guide channel 3 of appropriate location resistance sheet 4 is selected to perform the operation, location resistance sheet 4 above guide channel 3 can be kept out on vertebral body cortical surface of bone, so namely, the effect of controlling depth can be reached, an impetus can be produced again, when making bone grafting, bone grafting grain can be opened up reality by inner core 2 in vertebral body, finally reach maximum On graft area, reach final solid fusion, this reduces neural damage, reduce operation easier.
The non-detailed portion of this utility model is prior art.
