Abstract
The present invention belongs to the technical field of medical equipment and devices, and particularly relates to an easily-adjusted retractor for orthopedic surgery. The easily-adjusted retractor for the orthopedic surgery comprises two traction arms, and the front ends of the traction arms are symmetrically provided with traction teeth. The retractor is characterized in that the tail ends of the two traction arms are hinged through a first rotary shaft, rotary arms are connected with the same positions of the two traction arms through a second rotary shaft, the tail ends of the two rotary arms are connected through a third rotary shaft and a push rod, the rear portion of the push rod is provided with a screw rod penetrating through a base, and the base is fixed to the upper portion of the first rotary shaft. The retractor has the advantages that the two traction arms can be pushed open slowly and easily by rotating the screw rod to achieve the function of pulling bones, the retractor is simple in structure, safe, reliable and convenient to operate, strength can be controlled conveniently, pain of patients is relieved, and work difficulty of medical staff is lowered.
Description
(1) technical field
The invention belongs to field of medical equipment technology, particularly the easy tune type retractor of a kind of bone surgery.
(2) background technology
In orthopaedics, be quite high for the treatment of skeleton or the difficulty of operation, be all by manpower, the dislocation of fracture is pulled open carrying out resetting in the past in operative treatment, waste time and energy like this, but also easily increasing misery to patient even cause accident.At present, similar operation is all carry out auxiliary complete operation by some operating theater instruments, implement skeleton retract or tractive time, existing retractor is all that manpower directly acts on drawing arm, and dynamics is extremely difficult to be grasped, when skeleton is solid, be difficult to retract, now, will go into overdrive, but due to effect of inertia, strength is excessive for the moment, excessively will separate two drawing arms, great damage be caused to patient, easily causes medical tangle.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the easy tune type retractor of bone surgery that a kind of structure is simple, safe and reliable, easy to operate, be convenient to grasp dynamics.
The present invention is achieved through the following technical solutions:
The easy tune type retractor of a kind of bone surgery, comprise two drawing arms, drawing arm front end is arranged with respectively and retracts tooth, it is characterized in that: two drawing arm ends are hinged by the first rotating shaft, on two drawing arms, same position is connected with turning arm respectively by the second rotating shaft, and two pivot arm ends are connected with push rod by the 3rd rotating shaft, and push rod rear portion is provided with screw rod, screw rod is through base, and base is fixed on the first rotating shaft top.
Be provided with jump ring between two drawing arm ends, screw rod end is connected with handle.
The invention has the beneficial effects as follows: slowly can push two drawing arms gently open by rotary screw, reach the effect of tractive skeleton; Structure is simple, safe and reliable, easy to operate, be convenient to grasp dynamics, alleviates the misery of patient, reduces the work difficulty of medical worker.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is structural representation of the present invention;
In figure, 1 drawing arm, 2 retract tooth, 3 first rotating shafts, 4 second rotating shafts, 5 turning arms, 6 the 3rd rotating shafts, 7 push rods, 8 screw rods, 9 bases, 10 jump rings, 11 handles.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises two drawing arms 1, drawing arm 1 front end is arranged with respectively and retracts tooth 2, drawing arm 1 end is hinged by the first rotating shaft 3, on two drawing arms 1, same position is connected with turning arm 5 respectively by the second rotating shaft 4, two turning arm 5 ends are connected with push rod 7 by the 3rd rotating shaft 6, push rod 7 rear portion is provided with screw rod 8, and screw rod 8 is through base 9, and base 9 is fixed on the first rotating shaft 3 top.Be provided with jump ring 10 between two drawing arm 1 ends, screw rod 8 end is connected with handle 11.
Adopt the easy tune type retractor of a kind of bone surgery of the present invention, during use, first prop up or insert need between the skeleton that retracts by retracting tooth 2, turn clockwise handle 11 gently, screw rod 8 just can be advanced forward, heads on push rod 7 and advances, thus makes angle between two turning arms 5 increasing, now two drawing arms 1 just can strut to both sides, and then retract skeleton.Change the length of turning arm 5, when screw rod 8 advances same distance, space out between two drawing arms 1 also different, can the length of designed, designed turning arm 5 as required.The operation of this process, by means of the principle of lever, only needs rotary screw 8 gently, there will not be and firmly do not reach, more there will not be the problem overexerted, safe and reliable.Jump ring 10 can be beneficial to strutting of two drawing arms 1, after finishing using, it also can be made to playback fast.
Claims (2)
1. the easy tune type retractor of bone surgery, comprise two drawing arms (1), drawing arm (1) front end is arranged with respectively and retracts tooth (2), it is characterized in that: drawing arm (1) end is hinged by the first rotating shaft (3), two upper same positions of drawing arm (1) are connected with turning arm (5) respectively by the second rotating shaft (4), two turning arms (5) end is connected with push rod (7) by the 3rd rotating shaft (6), push rod (7) rear portion is provided with screw rod (8), screw rod (8) is through base (9), base (9) is fixed on the first rotating shaft (3) top.
