Description
Technical field
The utility model belongs to technical field of medical equipment, and in particular in a kind of bone surgery, bone plate slipped screw takes
Go out device.
Background technology
It is to treat the most frequently used mode of shaft fracture at present that bone plate is fixed with screw, is widely applied in clinic.Synthetism
Plate has medical steel and titanium alloy with screw common used material, after union, needs in most cases to take out interior fixation bone fracture plate, but
In clinical practice, tie as Slipped bolt, cold welding often occurs in a variety of causes, cause synthetism plate bolt take out it is difficult,
Situations such as can not taking out, waste time and energy, allow surgical doctor to feel simply helpless.It is especially severe in current conflict between doctors and patients, medical tangle frequency
In the case of sending out, even more require that surgical doctor can ensure that synthetism plate bolt completely takes out.Even if in these cases using tradition
Broken nail extractor and Slipped bolt extractor, cannot guarantee that synthetism plate bolt smoothly takes out, extend operating time, increase hand
Art bleeding, opportunities for contamination and operation risk, bury medical hidden danger.
Once the head of a nail is also often polished by situations such as Slipped bolt, cold welding occur and tie at present using tungsten bur in operation
After falling, then the bolt portion of residue is taken out after trepan reaming after bone plate is taken out, but polishing screw cap mistake is bored in wolfram steel
Cheng Zhong, metal fragment flash in tissue around, are particularly susceptible and stick on muscle, it is impossible to which flushing is cleaned out, and causes metal
Chip is retained in vivo, and postoperative film making has development, is caused patient to be discontented with and is caused dispute.
Utility model content
The purpose of this utility model is to solve technical problem present in prior art, there is provided a kind of simple structure,
Cheap, simple, convenient quick, safely and effectively bone plate slipped screw withdrawing device in bone surgery.
In order to achieve the above object, the utility model is employed the following technical solutions：In a kind of bone surgery, bone plate skids
Screw withdrawing device, bores including wolfram steel and trepan, also includes that the chip enclosing of the upper and lower opening being made up of at least three pieces baffle plates is tied
Structure, one of baffle plate of the chip enclosing structure are provided with sandwich, the sandwich built with magnet, the chip
Another piece of baffle plate bottom of enclosing structure is provided with attraction interface tube and attracts interface tube to be connected with the inside of chip enclosing structure.
Further, the chip enclosing structure be made up of four pieces of baffle plates and chip enclosing structure in it is up big and down small fall four
Prismatic table shape.
Further, the bottom of the chip enclosing structure is provided with draw-in groove.
Further, the width width 2mm of the width ratio bone plate of the draw-in groove.
Further, the magnet is thin slice magnet.
Further, the material of each baffle plate of the chip enclosing structure is medical steel.
Further, the thickness of the sandwich is 3mm.
Further, the external diameter for attracting interface tube is 8mm.
The utility model hinge structure has the advantages that：In bone surgery of the present utility model, bone plate is beaten
Sliding screw withdrawing device mainly includes the chip enclosing knot of wolfram steel brill, trepan and the upper and lower opening being made up of at least three pieces baffle plates
Structure, one of baffle plate are provided with sandwich, and sandwich is provided with attraction interface tube built with magnet on another piece of baffle plate,
During orthopaedics takes out synthetism plate bolt, if running into Slipped bolt, chip enclosing structure is stuck on bone plate, tungsten is used
Steel bores polishing screw cap, and the metal fragment for producing of polishing is surrounded by chip enclosing structure, if the material of synthetism plate bolt is medical
Steel, the metal fragment that polishing will be produced by magnet adsorb on baffle plate, if the material of synthetism plate bolt is titanium alloy, due to magnetic
Iron does not have suction-operated, and metal fragment is suctioned out from suction tube interface by the effect of suction tube, is solved in polishing well
During slipped screw, metal fragment flashes, and sticks in surrounding tissue blood, is particularly susceptible and sticks on muscle, it is impossible to rushes
The difficult problem cleaned out is washed, bone plate just smoothly can be taken out within a few minutes, is shortened operating time, go out in reducing art
Blood, opportunities for contamination and operation risk, eliminate medical hidden danger, it is to avoid medical tangle.In addition, the utility model simple structure,
It is cheap, simple, convenient quick, safe and effective, with good use value and application prospect.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
The utility model reference implication is as follows：1st, chip enclosing structure；2nd, baffle plate；3rd, sandwich；4th, suction tube
Interface；5th, draw-in groove；6th, bone plate；7th, synthetism plate bolt.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, bone plate slipped screw withdrawing device in a kind of bone surgery, bore including wolfram steel, trepan and by
The chip enclosing structure 1 of the upper and lower opening of four pieces of compositions of baffle plate 2, chip enclosing structure 1 is in the up big and down small shape of falling truncated rectangular pyramids, is made
Which can provide sufficiently large operating space and field of view, the material of 1 each baffle plate 2 of chip enclosing structure from suitable for reading when in use
For medical steel, one of baffle plate 2 of chip enclosing structure 1 is provided with sandwich 3, and the thickness of sandwich 3 is 3mm, interlayer
Structure 3 is sealed built with after thin slice magnet, and another piece of 2 bottom of baffle plate of chip enclosing structure 1 is provided with attraction interface tube 4 and attracts
Interface tube 4 is connected with the inside of chip enclosing structure 1, and the external diameter for attracting interface tube 4 is 8mm, with the conventional suction tube of operating room
Internal diameter is in the same size, and to facilitate connection to install suction tube, the bottom of chip enclosing structure 1 is provided with draw-in groove 5, the width ratio of draw-in groove 5
The width width 2mm of bone plate 6 so as to which energy convenient card increases stability during operation on bone plate, chip enclosing structure 1
Wide 50mm suitable for reading.
In the surgical procedure that orthopaedics takes out synthetism plate bolt 7, the fracture of synthetism plate bolt 7 as made by running into medical steel is beaten
It is sliding, first chip enclosing structure 1 can be stuck on bone plate 6, then polishing screw cap be bored with wolfram steel, using chip enclosing structure 1
Fence effect, the metal fragment for producing of polishing is limited in chip enclosing structure 1, four will not be scattered to surrounding tissue blood
In, and by the magnetic attracting force of thin slice magnet in sandwich 3, all of metal fragment can be adsorbed completely and be enclosed in chip
On the baffle plate 2 of gear structure 1.If synthetism plate bolt 7 is made up of titanium alloy, as thin slice magnet does not adsorb to titanium alloy chip
Negative pressure suction tube in operating room, now when titanium alloy synthetism plate bolt 7 is taken out, can be connected on attraction interface tube 4, by force by power
The titanium alloy chip produced in bruting process can be sopped up by big suction.So either medical steel or titanium alloy material are made
Synthetism plate bolt 7, the chip produced in bruting process can be completely removed, then will be surplus using trepan with conventional method
Remaining screw takes out.
