Description

Multifunction surgical field-of-view displaying device

This utility model is the medical operation apparatus, specifically, is the multifunction surgical visual field displaying unit that uses in the surgical operation.

In the surgery directly view operative process, cut, stop blooding, appear surgical field of view and stitching and be the basic step of operation.Yet fully appearing surgical field of view, is again the key that ensures that operation is successful.Surgical field of view commonly used at present appears apparatus, basically be according to operative site (as breast, abdomen, extremity and vertebra etc.) and requirements of operation, made the drag hook that comes in every shape, surgical staff directly with portable, draw, press, with make at operative site various accurately and flexibly the action.But doing the persistence tractive, when especially big or middle operation need fully appear surgical field of view, just must have the special messenger to operate, its muscle power often consumes bigger because of institute's station location is not good.In addition, when appearing surgical field of view and operation technique sometimes and influencing each other, often needing patient and assistant to change the position, also is very disadvantageous from the aseptic principle of strictness.

Also having a kind of surgical field of view to appear apparatus at present is various retractors, and it is special according to a certain position, can retract as symmetry.No matter be both wings, as rib retractor, double-vane stomach wall self-retaining retractor, (seeing the chief editor's of Ministry of Health of the People's Republic of China " medical apparatus and instruments specimen " 1977) or multiple wing, as three wings stomach wall self-retaining retractor, all must begin to have one group of symmetry to retract the effect of later competence exertion three wings.If in operation need make the pulling force of a certain layback hook on the symmetrical wing weaken or strengthen the time, will cause otch to dwindle simultaneously or enlarge, the ideal that directly influences surgical field of view appears.Concerning the three wings retractor, if the three wings pulling force will cause whole retractor to move greater than the summation of symmetry pulling force.In addition, the tractive of this class retractor, carry, the enforcement of action such as pressure is not too flexible, can not carry out simultaneously.And various retractors are special-purpose, and a kind of retractor can only be used in a part, can not be general.

The purpose of this utility model is to provide a kind of multi-functional surgical field of view displaying unit, what it can make various persistence of making any direction after being fixed on the drag hook shelf on demand through the drag hook or the fixing head of repacking carries, draws, presses work, can finish again asymmetric that retractor institute can not carry out carry, draw, pressure holding continues sexual act.More than action can replace the surgical staff tractive through adjusting after fixing, makes patient working area spaciousness, and is comfortable during operation, easy to operate, alleviates the labor intensity of surgical staff greatly.

Fig. 4 is that this utility model base portion A is to view.

The utility model is made up of base, vertical bull stick, horizontal bull stick and working head retained part. Vertically bull stick and horizontal bull stick are the armed lever that can carry out two above free degree activities. When work, base through screws is fastened on the band iron at operation table edge, and vertically the overcoat of bull stick part is connected with base, and bull stick can be made level or movement in vertical direction as requested in it. Horizontal bull stick part partly connects with the bull stick of being connected by transfer rack, and bull stick can move axially or 360 ° of rotations as requested in it. The working head retained part be connected the interior bull stick of bull stick part and connect, can settle as required various drag hooks or gland through repacking on the drag hook shelf, and can rotate at front pivoted frame face. The above several parts of process Adjustment and fastening just can fully appear surgical field of view with various drag hooks or the parked operative site that is fixed in patient of other glands of operation usefulness, is beneficial to patient's work.

Below, the embodiment during this utility model is incited somebody to action in conjunction with the accompanying drawings is described in detail:

Base portion of the present utility model mainly by last pressure frame 26, press down frame 29, bearing pin 27 is formed, bearing pin 27 connects upper and lower pressure frame, and fixing by split pin 28, when mounted, pressing down frame 29 can turn under bearing pin 27 rotations, then last pressure frame 26 is stuck on the band iron 31 at operation table edge, then, upwards reset, respectively screw 25 is screwed with two knurled nuts 30 pressing down frame 29, upper and lower pressure frame is compressed, and base has just obtained fixing.

Vertical bull stick part of the present utility model is mainly by interior bull stick 22, overcoat 24 and knurled nut 23 form, overcoat 24 welds to be fixed in and presses on the frame 26, its upper end tube wall is constant slope, and there is screw socket to cooperate with nut 23, interior bull stick 22 can be done 360 ° horizontal direction rotation as required or move axially up and down in overcoat 24, the position is locked with nut 23 after determining.

Horizontal bull stick part of the present utility model is mainly changeed fork 16, middle pivoted frame 17 and knurled nut 13 by overcoat 15, interior bull stick 14, back and is formed, interior bull stick 14 can move axially in overcoat 15 or 360 ° of rotations, overcoat 15 opening tube walls are constant slope, and there is screw socket to cooperate with nut 13, the position is after determining, with the nut 13 interior bull stick 14 that is locked.Overcoat 15 changes fork 16 with the back and is welded in one, the back is changeed fork 16 and is connected by bearing pin 20 with middle pivoted frame 17, fixing with split pin 21, middle pivoted frame 17 is welded in one with interior bull stick 22 tops of vertical bull stick part, in the middle pivoted frame 17 the rectangle notch that is no less than 5 is arranged, the back is changeed fork 16 and can be rotated at vertical around bearing pin 20, after the position is determined, the rectangle cross section at screw 18 middle parts is snapped among one of them of middle five rectangle notches of pivoted frame, then with knurled nut's 19 lockings, like this, horizontal bull stick part has just obtained fixing.
