Description of the drawings
In order to keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing to this practicality
It is novel to be preferably described in detail, wherein：
Fig. 1 is the structural schematic diagram of the utility model retractor.
Specific implementation mode
Below with reference to attached drawing, the preferred embodiment of the utility model is described in detail；It should be appreciated that preferably real
Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.
Reference numeral in Figure of description includes：Fixed body 1, supporting leg 2, strut 3, U-shaped push away hook 4, push rod 5, butterfly-type spiral shell
Mother 6, compression spring 7, clamping screw 8, hand holding handle 9, ring body 10, ball twist joint 11.
Embodiment is substantially as shown in the picture：A kind of controllable surgical incision retractor provided in this embodiment, including fixation
Body 1 and the pull device being arranged on fixed body 1 and haulage gear, the pull device are made of supporting leg 2 and strut 3, the branch
Leg 2 is at least two, is articulated on fixed body 1, and four are used in this example, certainly in various embodiments, supporting leg
Number can be arranged to different according to demand, and single supporting leg 2 is connected with U-shaped in one end far from fixed body 1 and pushes away hook 4, which pushes away
Hook 4 acts at operative incision, and strut 3 has quantity identical with supporting leg 2, makes the two to form one-to-one relationship, one
End is hinged by the ring body 10 being arranged on haulage gear, and the other end is hinged with corresponding supporting leg 2, the haulage gear
It is extended vertically through from top to bottom in fixed body 1；The haulage gear carries externally threaded push rod 5 by an one end, is fixed on push rod 5
Wing nut 6 on the other end, the compression spring 7 being set on push rod 5 and between fixed body 1 and wing nut 6 form,
The wing nut 6 is located at the top of fixed body 1, and the ring body 10 is located at the lower section of fixed body 1, is equipped in the fixed body 1
The internal thread being screwed on the external screw thread of push rod 5.
In use, making four supporting legs that certain angle be unfolded, then U-shaped is pushed away hook 4 and is acted on by rotating push rod 5 first
Incision, then, then slow rotating push rod 5, so that four supporting legs is gradually unfolded, it is readily available good to retract notch
Surgical field of view fully performed the operation convenient for doctor with appearing deep tissue and internal organs, i.e. 5 precession of push rod, then supporting leg 2 be unfolded,
If the rotation of push rod 5 is moved back, supporting leg 2 bounces back；In addition, the compression spring 7 is compressed during 5 precession of push rod, due to compression spring 7
Reaction force so that be locked between push rod 5 and fixed body 1, when only the rotation of push rod 5 is moved back, the compression spring 7 recovery could bounce back
Supporting leg 2.Meanwhile the supporting leg 2 has certain length so that the retractor makes medical staff have during retracting notch
Good visual-field space will not interfere, convenient for operation.
Sphere may be used in fixed body 1 and/or ring body 10 in the present embodiment, can also use hemisphere, and single support
Between bar 3 and ring body 10, between single supporting leg 2 and fixed body 1 by it is free to rotate and carry externally threaded ball twist joint
11 connection, the strut 3, supporting leg 2 the one end for being respectively further from ring body 10, fixed body 1 be equipped with indent and with ball twist joint 11
The internal thread that is screwed on of external screw thread, multiple ball twist joints 11 on the fixed body 1, ring body 10 are uniformly distributed on it same
In the cambered surface of horizontal plane, and the spacing between ball twist joint 11 adjacent two-by-two is equal.This way it is ensured that between supporting leg and fixed body
And between strut and ring body rotatably, it is convenient for support and Modulatory character of the strut to supporting leg.
Supporting leg 2 in the present embodiment is by pushing away rod set (unmarked) that hook 4 is connect with U-shaped and connecting and be socketed with fixed body 1
(unmarked) composition of telescopic bar core in rod set, the rod set are being equipped with clamping screw 8 with the flexible place of bar core.This
The length of supporting leg can be changed by adjusting the distance between rod set and bar core in sample, while it is solid to coordinate ball twist joint 11 that can change
Determine the center of gravity of body, is conducive to operation.
It is additionally provided with hand holding handle 9 on fixed body 1 in the present embodiment.In this way, medical staff is facilitated to hold, it is conducive to rotation butterfly-type
Nut 6 makes 5 precession of push rod or rotation move back, can also connect the hand holding handle with holder, the retractor is fixedly mounted.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, it is clear that this field
Technical staff spirit and scope of the various modification and variations without departing from the utility model can be carried out to the utility model.This
Sample, if these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology range it
Interior, then the utility model is also intended to include these modifications and variations.
