Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained in the following with the accompanying drawings and the embodiments.
As shown in fig. 1 to 4, the pedicle screw positioning soft tissue spreader comprises two longitudinal spreading baffles 1, two connecting rods 2 and a sliding assembly 3, wherein each longitudinal spreading baffle 1 is composed of a baffle bottom 11, a baffle middle 12 and a baffle upper 13 which are sequentially connected, and as shown in fig. 4, the two longitudinal spreading baffles 1 are distributed in a splayed shape. The longitudinal expanding baffle 1 is wider, and the bottom 11 of the baffle forms an angle with the middle 12 of the baffle, so that soft tissues on two sides and at the bottom are effectively expanded, and tissue damage is reduced. The included angle between the middle part 12 of the baffle plate and the upper part 13 of the baffle plate in the longitudinal distraction baffle plate 1 is 160 degrees, and the length of the upper part 13 of the baffle plate is longer, so that the influence of the baffle plate on the operation of instruments in the operation is avoided, and the cohesive angle of the vertebral arch nail is not influenced.
Each connecting rod 2 comprises a connecting rod body 21 and a connecting rod horizontal part 22 which are connected in sequence, the connecting rod body 21 in the connecting rod 2 is connected with the baffle middle part 12 of the longitudinal spreading baffle 1, and the position of the longitudinal spreading baffle 1 in the vertical direction can be effectively fixed after force is applied. Connecting rod somatic part 21 in the connecting rod 2 and vertically strut and be certain contained angle distribution on the vertical direction between baffle 1, be certain contained angle distribution on the horizontal direction between connecting rod somatic part 21 in connecting rod 2 and the connecting rod horizontal part 22 for sliding assembly 3 is located directly over the spinous process, makes things convenient for the art person to operate.
The sliding assembly 3 comprises a sliding guide rail 33, a first sliding base 31 and a second sliding base 32, wherein the first sliding base 31 is arranged on the sliding guide rail 33 and connected with the horizontal part 22 of the corresponding connecting rod 2, and the second sliding base 32 is arranged on the sliding guide rail 33 in a sliding manner and connected with the horizontal part 22 of the corresponding connecting rod 2; six fixing holes 35 are equidistantly distributed on the sliding guide rail 33 along the length direction of the sliding guide rail, and fixing screws 34 capable of being matched with the fixing holes 35 are arranged on the second sliding base 32.
