Abstract
The utility model relates to a latched plum-blossom needle extractor with spiral pressurizing. A spiral mechanism is composed of a screw rod and a screw disk, wherein, the front end of the screw rod is fixed with a sleeve tube for inserting a plum-blossom needle and a latch steel needle used for connecting together the plum-blossom needle and the sleeve tube, and the outer surface of the screw rod is sheathed with a sleeve barrel. When in use, the sleeve barrel props against a bone end, and the plum-blossom needle can be gradually extracted by continuously rotating the screw disk.
Description
This utility model relates to the technical field of medical instruments that is used for the synthetism operation.
The percussopunctator extractor that uses clinically at present mostly be the impacting type structure, and effort is used in not only operation inconvenience, and because single load bearing when using, and drag hook tensile strength is low, causes drag hook to break or stretching often, influences normally carrying out of performing the operation.
The purpose of this utility model provides a kind of screw press latched type percussopunctator extractor sturdy and durable, easy to use.
The technical solution of the utility model is: a spiral shell dish is installed on a screw rod, and the two constitutes a screw mechanism.The front end of screw rod is fixed with the sleeve pipe that is used for the plug-in mounting percussopunctator, also is fixed with one on the screw rod and is used for percussopunctator and telescopic joint together door bolt are plugged in draw point, is set with sleeve in the outside of screw rod.
The utility model has the advantages that: changed the unidirectional impact mode of existing percussopunctator extractor, pulling force is big and evenly mild, and easy to use laborsaving, wound is little, and is sturdy and durable, can not influence normally carrying out of operation.
Fig. 1 is this utility model axonometric chart, shows its overall structure;
Fig. 2 is the connection diagram of sleeve pipe and remainder;
Fig. 3 is the structural representation of spiral shell dish.
In the embodiment that accompanying drawing provides, this utility model is that a spiral shell dish 2 is installed on a screw rod 1, and the two constitutes a screw mechanism.The front end of screw rod 1 is fixed with a sleeve pipe 6, and the rear end of percussopunctator 7 to be extracted can be inserted in this sleeve pipe 6.Be fixed with a door bolt on the screw rod 1 and plug in draw point 5, the front end of this draw point 5 has bending, and on the sleeve pipe 6 and percussopunctator 7 rear ends all have aperture, and the bending part of the plug in draw point 5 of door bolt inserts aperture and sleeve pipe 6 and percussopunctator 7 can be linked together.Outside at spiral shell dish 2 one side screw rods 1 and sleeve pipe 6 is set with sleeve 4.During use, the front end of sleeve 4 withstands epiphysis, and its rear end is inserted on the bossing of spiral shell dish 2 one middle side parts, rotates spiral shell dish 2 continuously, and screw rod 1 can drive percussopunctator 7 and slowly extract.Withdraw from resistance when big when running into percussopunctator 7, can load onto cross bar 3, to strengthen the rotation dynamics at the periphery of spiral shell dish 2.This cross bar 3 also can be used as the percussopunctator driver and uses when taking off.
