Description
Technical field
The utility model belongs to technical field of medical instruments, and in particular to a kind of hand-rail type cervical vertebra retractor retracts plate.
Background technology
Then tracheae, blood vessel etc. are retracted to throat, it is necessary to cut from throat side by cervical operation by retractor
Opposite side, because retractor side stress is larger, cause retractor easily to shift, this gives the difficulty brought of operation, mesh
Preceding way is, it is necessary to which a people hauls retractor all the time from side, to ensure visual area, or by retractor and operation table
There is provided traction force for equipment fixation.Complex operation, it is inconvenient for use.
Interfered sometimes with retracting plate in addition, cervical vertebra horizontal stroke is convex, cause to retract not thorough, influence visual area.
The content of the invention
The utility model, there is provided one kind is easy to use, can avoid retracting aiming above mentioned problem without aid
There is the traction plate offset in device.
In order to realize above-mentioned purpose of the present utility model, the utility model is adopted the following technical scheme that, the utility model bag
Rubbing board body, plate body upper end is provided with the connector being connected with hand-rail type retractor, it is characterised in that：It is provided with the middle part of plate body lower end
Gap, plate body surface is provided with the connection semi-ring of projection, connection semi-ring and is provided with pilot pin.
As a kind of preferred scheme of the present utility model, plate body surface both sides are provided with connection semi-ring.
As another preferred scheme of the present utility model, the connection semi-ring includes corresponding upper semi-ring and lower half
Back-moving spring is provided with above ring, upper semi-ring, the pilot pin upper end is provided with the press head contacted with back-moving spring.
The beneficial effects of the utility model：1st, the utility model is by setting gap, horizontal convex mutual mistake that can be with cervical vertebra
Open, it is to avoid interfere, cause to retract halfway problem.
2nd, when needing to place retractor skew, after the utility model is retracted in place, pilot pin can be pushed, consolidates pilot pin
Determine onto vertebra, so as to provide retracting force, it is to avoid the situation for retractor skew occur occurs.
3rd, the utility model in plate body both sides by being respectively provided with pilot pin, it is ensured that at least below the pilot pin of side
It is corresponding with vertebra, it is to avoid to retract the vertebra that position not can be used for positioning.
4th, the utility model is good to pilot pin guide effect by the way that connection semi-ring is set into upper semi-ring and lower semi-ring, keeps away
Exempt from pilot pin crooked；Also, by setting back-moving spring, when not in use, pilot pin bounces back in the presence of back-moving spring, keeps away
Exempt to stab tissue.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 side view.
1 it is gap in accompanying drawing, 2 be pilot pin, 3 be lower semi-ring, 4 be upper semi-ring, 5 be back-moving spring, 6 be press head, 7 is
Plate body, 8 are connector.
Embodiment
The utility model includes plate body 7, and the upper end of plate body 7 is provided with the connector 8 being connected with hand-rail type retractor, its feature
It is：Gap 1 is provided with the middle part of the lower end of plate body 7, the surface of plate body 7 is provided with the connection semi-ring of projection, connection semi-ring and is provided with
Pilot pin 2.
As a kind of preferred scheme of the present utility model, the surface both sides of plate body 7 are provided with connection semi-ring.
As another preferred scheme of the present utility model, the connection semi-ring includes corresponding upper semi-ring 4 and lower half
Ring 3, the upper top of semi-ring 4 is provided with back-moving spring 5, and the upper end of pilot pin 2 is provided with the press head 6 contacted with back-moving spring 5.
In use, plate body 7 is connected by connector 8 with hand-rail type retractor, after otch is retracted, it can press as needed
Lower pilot pin 2, makes pilot pin 2 be fixed on vertebra, so that retractor be fixed.
It is understood that specifically described above with respect to of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with
The utility model is modified or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
