Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in figure 1, the rib fracture reduction involution device convenient to operate comprises a main rod 1, a rotary cylinder 2, a bearing 3, a sliding sleeve 4 and a rotary sleeve 5. The main rod 1 is of a long-strip cylindrical structure, and external threads are arranged on the outer side wall of the main rod. The rotary cylinder 2 is sleeved on the main rod 1 in a threaded manner so that the rotary cylinder 2 can slide along the main rod 1 in the axial direction by rotating the rotary cylinder 2, and convex particles 9 used for increasing friction force when the rotary cylinder 2 rotates are arranged on the outer side wall of the rotary cylinder 2. The two ends of the main rod 1 are respectively provided with a limiting block 10 for preventing the rotating cylinder 2 from being separated from the main rod 1. The bearing 3 is sleeved on the main rod 1 in a clearance mode and corresponds to one end of the rotary cylinder 2, and the outer ring of the bearing is fixedly connected with one end of the rotary cylinder 2. The sliding sleeve 4 is sleeved on the main rod 1 in a clearance mode and corresponds to the position, far away from one side of the rotating cylinder 2, of the bearing 3, one end of the sliding sleeve 4 is fixedly connected with the inner ring of the bearing 3, and the other end of the sliding sleeve is far away from the rotating cylinder 2 along the axial direction of the main rod 1 by a preset distance. One end of the main rod 1 is provided with a groove 11 for arranging the rotary sleeve 5, and the rotary sleeve 5 is rotatably sleeved on the groove 11. And the sliding sleeve 4 and the rotating sleeve 5 are respectively provided with a fixing clamp which clamps the ribs on two sides of the fracture line after being folded and enables the ribs to be aligned.

As shown in fig. 2, the fixing clip includes a first clip arm 6 and a second clip arm 7. The upper end of the first clamping arm 6 is fixedly connected with the sliding sleeve 4 or the rotating sleeve 5, and the lower end of the first clamping arm extends downwards for a preset distance. The second clamping arm 7 is arranged at one side of the lower part of the first clamping arm 6, the first clamping arm 6 and the second clamping arm 7 are connected together through a screw 8, and the screw 8 enables the first clamping arm 6 and the second clamping arm 7 to be mutually folded or unfolded through adjusting the relative positions of the first clamping arm 6 and the second clamping arm 7.

The utility model discloses except that the fixed mode of slip of sliding sleeve 4 is different with the patent that cites in the background art, all the other operations are unanimous. Therefore, the sliding fixing manner of the sliding sleeve 4 is mainly described herein, and the rest (see the cited patent documents) is not described again, specifically as follows:

when the position of sliding sleeve 4 needs to be adjusted, rotatory section of thick bamboo 2 of manual rotation because 2 screw thread suits of rotatory section of thick bamboo are on mobile jib 1, rotate rotatory section of thick bamboo 2 after, rotatory section of thick bamboo 2 can be along the endwise slip of mobile jib 1. Meanwhile, the outer ring of the bearing 3 rotates synchronously with the rotary cylinder 2, and the inner ring only slides along with the rotary cylinder 2. And the sliding sleeve 4 is fixedly connected with the inner ring of the bearing 3, and finally the sliding sleeve 4 is driven to slide on the main rod 1 along the axial direction of the main rod 1 after the rotating cylinder 2 is manually rotated. Because the screw thread suit of rotary drum 2 is on mobile jib 1, the rotary drum 2 will be fixed after stopping to rotate rotary drum 2, and sliding sleeve 4 also can be fixed still, and then need not to increase this operating procedure fixed to sliding sleeve 4 again. Meanwhile, the sliding sleeve 4 does not reverse back after the rotation of the rotary cylinder 2 is stopped before the sliding sleeve 4 has not reached the desired position. Through the connection design of the bearing 3, a sawtooth structure in the reset involution device is omitted, and the sawtooth structure is prevented from scratching patients or medical staff. Finally, after the sliding sleeve 4 reaches the expected position, the position of the sliding sleeve is fixedly connected with the main rod 1 through the rotating cylinder 2 in a threaded manner, the fixing is reliable, and the sliding sleeve is not easily interfered by the outside to displace.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
