Example 1
Fig. 1 is a front view of a gun-type reduction forceps for cervical vertebrae of the present invention;
fig. 2 is a perspective view of the gun-type reduction forceps for cervical vertebrae of the present invention.
As shown in fig. 1 and 2, the present embodiment provides a cervical spine gun-type reduction forceps, which includes: the device comprises an inner sleeve 1, an outer sleeve 2 and a linkage mechanism 3 connected with the inner sleeve 1; the linkage mechanism 3 is suitable for driving the inner sleeve 1 to move backwards along the outer sleeve 2, and the clamping part 11 at the front end of the inner sleeve 1 enters the outer sleeve 2, so that the clamping part 11 clamps the cervical vertebra nail. Drive inner skleeve 1 through link gear 3 and move backward along outer sleeve 2, then the clamping part 11 of inner skleeve 1 front end can get into in the outer sleeve 2 to guarantee that clamping part 11 presss from both sides tight cervical vertebra nail, can not drop, thereby be convenient for better carry out a series of operations to the cervical vertebra nail when the operation.
Wherein, the front end of the outer sleeve 2 is matched with the opening radian of the clamping part 11, so that the clamping part 11 can smoothly enter the outer sleeve 2. The diameter of the clamping part 11 is slightly larger than the inner diameter of the outer sleeve 2 and is in a horn shape, when the inner sleeve 1 clamps the cervical vertebra nail, the cervical vertebra nail is in a state that the cervical vertebra nail can not fall off, when the inner sleeve 1 moves backwards along the outer sleeve 2, the clamping part 11 enters the outer sleeve 2, and then the clamping part 11 can be folded to enable the cervical vertebra nail to be locked.
Optionally, the linkage mechanism 3 includes: a first sliding block 31, a second sliding block 32, and a first forceps handle 33 and a second forceps handle 34 hinged with the first sliding block 31 and the second sliding block 32 respectively; the first forceps handle 33 and the second forceps handle 34 are connected through a hinge; the first and second handles 33, 34 are pressed to move the second slider 32 toward the first slider 31. When the first clamp handle 33 and the second clamp handle 34 are pressed, the second sliding block 32 is close to the first sliding block 31, and when the second sliding block 32 is loosened, the first sliding block 31 is far away from the second sliding block 32, so that the structure is simple, and the operation is convenient.
In this embodiment, the first slider 31 and the second slider 32 are both U-shaped sliders; the first sliding block 31 is clamped in the grooves 21 symmetrically arranged on the outer wall of the outer sleeve 2; the second slide block 32 is clamped in the slide holes 22 symmetrically arranged on the outer wall of the outer sleeve 2; the first and second handles 33, 34 are pressed to move the second slider 32 along the sliding hole 22 and the inner sleeve 1 along the outer sleeve 2.
Specifically, the U-shaped opening of the first slider 31 is clamped in the groove 21 on the outer wall of the outer sleeve 2, so that the first slider 31 is limited from moving, the U-shaped opening of the second slider 32 is clamped in the sliding hole 22 on the outer wall of the outer sleeve 2, and the second slider 32 is clamped in the clamping groove on the inner sleeve 1, so that the second slider 32 can drive the inner sleeve 1 to move. When the first and second handles 33, 34 are pressed, the second slider 32 moves toward the first slider 31 along the sliding hole 22, and the second slider 32 drives the inner sleeve 1 to move backward along the outer sleeve 2 along the sliding hole 22, so that the holding portion 11 enters the outer sleeve 2.
In this embodiment, the first slider 31 and the second slider 32 are connected to a guide rail in a penetrating manner. By arranging the guide rail, the second sliding block 32 can not incline when moving along the sliding hole 22, so that the second sliding block can effectively move better, and a better guiding effect is achieved.
In the embodiment, a trigger mechanism 4 is arranged at the hinged position of the first and second clamp handles; the trigger mechanism 4 includes: a trigger 41, a return torsion spring, and a positioning rack 42; the trigger 41 is pressed to cause the latch of the trigger 41 to catch on the positioning rack 42 to fix the opening and closing size of the first and second handles 33, 34. Through the meshing of latch and positioning rack 42, the opening and closing sizes of first forceps handle 33 and second forceps handle 34 are locked, so that the position of second slider 32 is limited, the inner sleeve 1 is effectively prevented from extending forwards, and the cervical vertebra nail is ensured to be firmly fixed.
In the present embodiment, a reset mechanism 5 is disposed between the first and second handles 33, 34. The reset mechanism 5 can help the pressed first forceps handle 33 and the pressed second forceps handle 34 to be better restored, and the service life of the first forceps handle 33 and the second forceps handle 34 is prolonged.
Optionally, the reset mechanism 5 includes: resetting the spring piece; the two sides of the reset spring piece respectively abut against the inner sides of the first clamp handle 33 and the second clamp handle 34. The first and second clamp handles 33, 34 can be restored to their original shapes by the return spring piece.
