The invention discloses a shell rotary-type clamping needle fixing dental implant structure and a use method, the shell rotary-type clamping needle fixing dental implant structure is used for alveolarbone, and the shell rotary-type clamping needle fixing dental implant structure comprises an implanting rod with an inserting hole formed along the axial direction; a inserting rod to be inserted into the inserting hole; a shell to be connected to the implanting rod in a sleeved mode and in threaded connection with the implanting rod; two clamping needles to be connected to the implanting rod through a second elastic piece, the two clamping needles are oppositely arranged, notches are formed in the opposite ends of the two clamping needles, and the second elastic piece is used for driving theclamping needles to move in the axis direction of the implanting rod; and the shell is used for driving the inserting rod to be inserted into the notches to drive the clamping needles to protrude from the peripheral wall of the shell. The shell is arranged for driving the clamping needles to be inserted into the alveolar bone, so that the dental implant structure is convenient to operate and use;due to the fact that the shell and the clamping needles are arranged, so that damage to the alveolar bone caused by screw-in of threads can be avoided when the dental implant structure is implanted;and the diameter of the arranged shell is larger than that of the implanting rod, thus being more convenient when driving.

The invention discloses a needle insertion carrier for a thumb-tack needle body. The carrier comprises a base body, and a plurality of needle body locating parts are arranged in the base body and usedfor locating the thumb-tack needle body; clamping mechanisms are arranged in all the locating parts and make linear reciprocating movement under driving, and therefore the thumb-tack needle body is clamped or loosened. Compared with the prior art, the carrier stably locates the thumb-tack needle body and is beneficial for full-automatic needle insertion, reasonable and concise in structural design and convenient to maintain.
