Abstract
The present invention provides a kind of backbone clamping device, including holding piece body, gripper jaw, locking device, the gripper jaw be two and be distributed in holding piece body two ends it is symmetrical, the holding piece body center position sets strip hollow out notch, the end of the gripper jaw is provided with contiguous block, the contiguous block is embedded in the dovetail groove of hollow out pocket bottom, the locking device is made up of clamping screw with screwed hole immediately below hollow out notch is arranged at, and described clamping screw runs through the screwed hole interconnection of hollow out notch and contiguous block immediately below it.By controlling the clamping screw at the top of contiguous block, the spacing regulation between control gripper jaw, and the embedded connection dovetail groove of contiguous block are realized, can stability of the lifting device in clamping.
Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of backbone clamping device.
Background technology
With continuing to develop for present social economy, the living standard of people is also constantly being lifted, for quality of the life
Pursuit is also differed, particularly the physical condition of itself.
In present life, because the operating pressure of majority of populations is big, the people of particularly long-term sitting operation
, the disease situation occurred of backbone is especially prominent, and long-term spinal disease can have a strong impact on the healthy of people, while existing
Life in, the general spinal disease operative treatment that solves is the most thorough, but operative treatment can touch a variety of of backbone position
Nerve, processing, which does not allow, can cause the failure of operation, it is necessary to the backbone fastness of strict fixed operative site, just can ensure that operation
It is normally carried out.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of backbone clamping device, can further it improve for ridge
The stability of the fixed clamp at post position.
To realize object above, the present invention is achieved by the following technical programs：
A kind of backbone clamping device, including holding piece body, gripper jaw, locking device, the gripper jaw are two and divided
Cloth is symmetrical at the two ends of holding piece body, and the holding piece body center position sets strip hollow out notch, the gripper jaw
End is provided with contiguous block, and the contiguous block is embedded in the dovetail groove of hollow out pocket bottom, and the locking device is by locking screw
Bolt runs through hollow out notch and its underface contiguous block with screwed hole composition immediately below hollow out notch, described clamping screw is arranged at
Screwed hole be connected with each other.
Further, the gripper jaw includes 3 reclinate pawl bar compositions.
Further, the head diameter of the clamping screw is more than the width of hollow out notch.
Further, the side of the hollow out notch is provided with scale marker.
Further, it is connected with back-moving spring along the insertion of dovetail groove direction between the contiguous block.
Further, the grab bar medial surface of the gripper jaw is provided with groove.
Further, the depth of the groove is 0.2-0.5mm.
It is embedded in by the contiguous block designed on device in dovetail groove, then by controlling clamping screw along strip hollow slots
Mouth activity, realizes and drives the spacing between gripper jaw to change, while contiguous block is embedded in dovetail groove, greatly improve dress
Put in actual use, incident to rock, whole device simple operation, can be further generalized in actual popularization.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, come for those of ordinary skill in the art
Say, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
The holding piece body overlooking the structure diagram of Fig. 1 present invention；
The holding piece body bottom portion structural representation of Fig. 2 present invention；
The holding piece body side structure schematic diagram of Fig. 3 present invention；
The side section part structural representation of Fig. 4 present invention.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.Based on the embodiment in the present invention,
The every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, belongs to this hair
The scope of bright protection.
As Figure 1-4, the present invention provides a kind of backbone clamping device, including holding piece body 1, gripper jaw 2, locking dress
Put, gripper jaw 2 be two and be distributed in holding piece body 1 two ends it is symmetrical, the central part of holding piece body 1 sets strip hollow out
Notch 3, the end of gripper jaw 2 is provided with contiguous block 21, and contiguous block 21 is embedded in the dovetail groove 12 of the bottom of hollow out notch 3, can
Realize that contiguous block 21 drives setting direction of the gripper jaw 2 along dovetail groove 11 to be moved, while locking device is by clamping screw 4
Constituted with the underface screwed hole 42 of hollow out notch 3 is arranged at, clamping screw 4 is through hollow out notch 3 and contiguous block immediately below it
Screwed hole 42 is connected with each other.And contiguous block 21 is embedded in dovetail groove 11, under the extruding of clamping screw 4, contiguous block is realized
Gap is not present between 21 and dovetail groove 11, it is to avoid what is be also easy to produce when being clamped between it rocks.
Further, gripper jaw 2 includes 3 reclinate pawl bar compositions, is easy to step up backbone position during clamping.Locking
The diameter of nut 41 of bolt 4 is more than the width of hollow out notch 3.Whole device is in use, first unscrewed clamping screw 4, so
The spacing between two clamping screws 4 is controlled afterwards, so as to realize the change in location between gripper jaw 2, then tightens clamping screw
4, realize that the position between gripper jaw 2 is fixed.
The side of hollow out notch 3 is provided with scale marker 31, the spacing between clamping screw 4 can be shown in real time, so as to sentence
The distance between disconnected gripper jaw 2.
Between contiguous block 21 back-moving spring 12 is connected with along the insertion of the direction of dovetail groove 11.
The grab bar medial surface of gripper jaw 2 is provided with groove.The depth of groove is 0.2-0.5mm, to be lifted in gripper jaw 2
Skid resistance during side gripper.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
The present invention is described in detail, it will be understood by those within the art that：It still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent substitution to which part technical characteristic；And these modification or
Replace, the essence of appropriate technical solution is departed from the spirit and scope of various embodiments of the present invention technical scheme.
