Abstract
The invention discloses a broken-nail extractor for orthopedics, in particular relates to a device for extracting a surgical fixation nail, belonging to surgical medical apparatus. The broken-nail extractor is characterized by comprising a drill hole guider, a drill head and a spiral nail-extractor, wherein one end of a guider connecting rod of the drill hole guider is provided with a guider handle and the other end is provided with a guider head shaped as a Chinese character Chang; the horizontal section of the guider head is provided with a guide hole for mounting the drill head; the oblique section of the guider head is provided with an auxiliary positioning nail; the broken-nail extractor is T-shaped; the upper end of a broken-nail extractor rod is provided with a broken-nail extractor handle perpendicular to the broken-nail extractor rod; the lower end of the broken-nail extractor rod is provided with a broken-nail extractor thread head with a conical truncate; and the thread direction of the broken-nail extractor thread head is a reverse thread, namely a left-hand thread. The broken-nail extractor has the advantages that a broken nail can be accurately positioned, drilled and extracted; the angle of the guide hole can be accurately adjusted and fixed according to requirements of a surgical part by the device so as to ensure that the direction of the drill hole is consistent with the direction of the central line of the broken nail; and thus the injury to the human body is relieved in the broken-nail extracting process, and the pain of a patient is relieved.
Description
Technical field
The invention belongs to surgical medical equipment, particularly take out the device of surgical fixation pin.
Background technology
Metallic screw is the fixedly apparatus of usefulness of the orthopaedics used always, during the fracture fixation of being expert at clinically, has the situation of disconnected (cunning) nail to take place often, and operation is compelled termination when disconnected (cunning) nail takes place, and the process of whole fracture fixation is had to and started anew.It is a very complicated thing that disconnected (cunning) nail takes out, and wastes time and energy, and traditional broken nail taking-up instrument is a trepan shape; Get nail weak effect, time-consuming long, bigger to bone destruction, and get nail again after needing steel plate to dismantle down fully, the green bone hole can not utilize again; Very big inconvenience is brought to whole surgery in the steel plate position of need remapping, and has increased the risk of iatrogenic refracture; Increased operating time, patient's bleeding is more, and the postoperative infection probability strengthens.The self-control device for taking out broken nail motility that has is relatively poor, does not reach purpose easily and efficiently.
Summary of the invention
Use inconvenient deficiency in order to overcome existing device for taking out broken nail, the present invention provides a kind of orthopaedics device for taking out broken nail and method for using thereof, and this orthopaedics device for taking out broken nail not only is easy to accurate location, and little to body injury in the taking-up process.
The technical solution adopted for the present invention to solve the technical problems is: a kind of orthopaedics device for taking out broken nail; It is characterized in that: form by drilling director, drill bit, spiral nail-fetching device three parts; Guider connecting rod one end of described drilling director has on the horizontal segment of guider head the pilot hole that drill bit is used is installed for the guide handle other end is equipped with the guider head of factory's font, the assist location pin is housed on oblique section of the guider head; Described nail-fetching device is T-shaped; Perpendicular nail-fetching device handle is equipped with in nail-fetching device bar upper end, and the lower end is Frusto-conical nail-fetching device thread head, and its hand of spiral is that reverse thread is a left hand thread.
Described assist location pin is weldingly fixed on the guide head.
Described assist location pin is connected with the guider head thread.
Described nail-fetching device handle is a cannula-like, and the nail-fetching device handlebar is housed in the sleeve pipe.
Described Frusto-conical nail-fetching device thread head, the thread head front end is less than bore diameter 0.5-1mm, and the rear end is greater than bore diameter 1-2mm, reach 15-25mm.
The method for using of orthopaedics device for taking out broken nail is characterized in that: mainly comprise the steps:
A. location: the pilot hole of drilling director is aimed at the broken nail head, and regulate pilot hole and broken nail fully in the same way,
B. boring: the drill bit of electric drill is put into pilot hole, start electric drill and on broken nail, hole, drilling depth does
C. get broken nail: the thread head of spiral nail-fetching device is inserted the left-handed spiral nail-fetching device that promptly is rotated counterclockwise in the boring; Reverse mantle fiber is carried on the back in the broken nail hole; Nail-fetching device closely contacts with broken nail; Because the screw thread of the thread head of spiral nail-fetching device is that left hand thread is opposite with the broken nail screw thread, can broken nail be screwed out in human body left-handed promptly being rotated counterclockwise in the process.
Method for using of the present invention is that the pilot hole of drilling director is aimed at the broken nail head; And regulate pilot hole and broken nail fully in the same way; The drill bit of electric drill is put into pilot hole, start electric drill and on broken nail, hole, the thread head with the spiral nail-fetching device inserts left-handed (being rotated counterclockwise) spiral nail-fetching device in the boring then; Reverse mantle fiber is carried on the back in the broken nail hole; Nail-fetching device closely contacts with broken nail, because the screw thread of the thread head of spiral nail-fetching device is that left hand thread is opposite with the broken nail screw thread, in left-handed (being rotated counterclockwise) process, can broken nail be screwed out in human body.Because the auxiliary fixing pin of drilling director is connected with the guider head thread; Can regulating its length according to the needs of operative site, can to regulate the angle in fixed guide hole more convenient, accurately consistent with the broken nail centrage with the direction that guarantees boring; Alleviate and get of the damage of nail process, alleviate patient's pain human body.
The invention has the beneficial effects as follows and accurately to locate, hole, take out broken nail; This apparatus can be consistent with the broken nail centrage with the direction that guarantees boring according to the angle that the needs of operative site are regulated the fixed guide hole accurately; Alleviate and get of the damage of nail process, alleviate patient's pain human body.
