Detailed Description
The following describes the embodiments of the present invention in further detail with reference to fig. 1 to 5.
As can be seen from fig. 1 to 5, the single-hand retractor for neurosurgery comprises a first body 1 and a second body 2 which are hinged to each other, the rear ends of the first body 1 and the second body 2 are both provided with a ring 3, the front ends of the first body 1 and the second body 2 are both provided with a retraction arm 4, the end part of the retraction arm 4 is provided with a pusher dog 5, the first body 1 is provided with a rotating block 6 at the position hinged to the second body 2, the inside of the second body 2 is provided with a friction plate 7 attached to the outside of the rotating block 6, one end of the friction plate 7 is rotatably fixed in the second body 2, the other end of the friction plate 7 is connected with a connecting rod 8 located in the second body 2, the second body 2 is provided with a pusher block 9 connected with the connecting rod 8, the pusher block 9 extends out of the second body 2, the connecting rod 8 is provided with a locking groove 10, the inside of the second body 2 is provided with a locking rod 11, and the locking groove 11 is inserted into the locking groove 10 to enable the friction plate 7 to.
The pusher dog 5 is detachably arranged at the end part of the retraction arm 4.
The end part of the retraction arm 4 is provided with a mounting groove 12, and the pusher dog 5 is fixed in the mounting groove 12 through a screw.
The second body 2 is internally provided with a spring 13 connected with the shifting block 9, and the spring 13 pushes the shifting block 9 outwards.
The inner end of the locking rod 11 is wedge-shaped, and the outer end of the locking rod 11 is provided with a pull ring 14.
When the utility model is used in a concrete way,
the pusher dog 5 is arranged in a mounting groove 12 at the front end of the retraction arm 4 and is fixed by screws, a doctor holds the retractor by one hand, the thumb and the middle finger of the right hand are respectively used for operating the first body 1 and the second body 2, then the pusher dog 5 is extended into the position of a patient needing to be retracted, the pusher dog 5 clamps the muscle or skin of the patient, the pull ring 14 is pulled to pull out the locking rod 11, the index finger of the right hand is used for pressing the pusher dog 9, the connecting rod 8 is driven to enable the friction plate 7 to be far away from the rotating block 6, so that the first body 1 and the second body 2 can rotate, after the pusher dog 5 is controlled to be expanded to a proper angle by the doctor, the pusher dog 9 is loosened, the locking rod 11 is pushed back into the second body 2 by the index finger of the right hand, the locking rod 11 enters the locking groove 10, the friction plate 7 is tightly pressed on the rotating block 6, and the relative displacement of the rotating block 6 and, thereby locking the rotation between the first body 1 and the second body 2 and playing a role of fixing the angle of the retracting arm 4.
For the convenience disinfect to pusher dog 5, pusher dog 5 detachable is fixed at 4 front ends on the arm that pulls off, carries out degree of depth disinfection to pusher dog 5 alone around the use, avoids infecting the patient, and detachable setting can the selective allocation of pusher dog 5 of different specifications to be used for different positions.
The shifting block 9 is pushed by the spring 13, when the shifting block 9 is not pressed by fingers, the shifting block 9 is pushed by the spring 13, so that the connecting rod 8 presses the friction plate 7 on the rotating block 6 to play a role in fixing, after a doctor uses the retractor to retract the opening of a patient, the fixing effect can be played as long as the fingers are loosened, the injury to the patient caused by the change of the angle of the retracting arm 4 is avoided, and the locking rod 11 is conveniently further used for fixing.
The inner end of the locking rod 11 is wedge-shaped and is conveniently inserted into the locking groove 10, when the locking rod 11 is inserted into the locking groove 10, the friction plate 7 is tightly attached to the outside of the rotating block 6, and the resilience force received on the pusher dog 5 is not enough to overcome the friction force to enable the first body 1 and the second body 2 to rotate relatively.
Compared with the prior art, the utility model, can operate by one hand, more convenient when checking the treatment to the patient, do not need both hands cooperation when fixed retractor angle, more rapid accuracy shortens the time of treatment, and retractor angle just can produce the change when the operation, can not take place because medical personnel's carelessly causes retractor angle change to hurt the condition of patient.
