Abstract
The utility model relates to Orthopeadic Surgery the field of medical instrument technology, more particularly to a kind of intramedullary nail aims at set, the contour structures of 8-shaped are just matched with the long slot hole on intramedullary nail, mutually independent upper through-hole and lower through-hole are directed at long slot hole simultaneously, two intramedullary nails can be accurately implanted into desired position out of upper through-hole and lower through-hole respectively, and implantation process is reliable and stable, no shaking.
Description
Technical field
The utility model relates to Orthopeadic Surgery the field of medical instrument technology more particularly to a kind of intramedullary nail to aim at set.
Background technique
Intramedullary nail is the prefered method of the long tubular bone fractures such as current treatment femur, shin bone, and the biology for belonging to elasticity is solid
Fixed, stress distribution is uniform, influences on fracture end smaller.It is easily-deformable after insertion long bone but since intramedullary nail is long,
Especially femur is in certain arc, and internal stenosis can make distal lockhole position change, so that distal locking nail is very
It is difficult to get access, cause operating time to extend, complication increases, and clinically extremely challenging problem.Pertinent literature report has
The distal locking nail failure rate of sighting device is still up to 29.2% or so, and femoral interlocking nail distal locking nail failure rate is higher.Therefore pass through
It aims at set and carrys out the entrance of auxiliary intra medullary nail, to improve the accuracy and stability of intramedullary nail implantation.Locking nail hole on intramedullary nail
It would generally be designed to long slot hole 100 (as shown in Figure 1), static add is realized according to the different demand of patient when its object is to perform the operation
Pressure or dynamic pressurized, to realize that this function needs design corresponding elongated slot sighting device on mating instrument, with individually taking aim at
It is easy to appear shaking when quasi- set, takes aim at inaccurate technical problem.
Utility model content
Technical problem to be solved by the utility model is: aiming at set with single to solve long slot hole in the prior art
When be easy to appear shaking, take aim at inaccurate technical problem, the utility model provides a kind of intramedullary nail and aims at set.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of intramedullary nail aims at set, including sleeve
Ontology, the shape in sleeve body section are 8-shaped, have mutually independent upper through-hole and lower through-hole, upper through-hole in sleeve body
In the upper semisection 8-shaped of sleeve body, lower through-hole is located in the lower semisection 8-shaped of sleeve body, upper through-hole and lower through-hole
Central axis be parallel to each other and be located at sleeve body among.
For the ease of installation, the outer ring of the end of the sleeve body is provided with multi-turn limiting slot, and multi-turn limiting slot is covering
The outer ring of the end of cylinder ontology, which is continuously arranged, forms waveform.
The utility model has the beneficial effects that the utility model intramedullary nail aim at set, the contour structures of 8-shaped just and
Long slot hole on intramedullary nail matches, and mutually independent upper through-hole and lower through-hole are directed at long slot hole simultaneously, can will be in two marrows
Nail is accurately implanted into desired position out of upper through-hole and lower through-hole respectively, and implantation process is reliable and stable, no shaking.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model intramedullary nail.
Fig. 2 is the structural schematic diagram that the utility model intramedullary nail aims at set.
Fig. 3 is the A direction view of Fig. 2.
In figure: 1, sleeve body, 11, upper through-hole, 12, lower through-hole, 13, multi-turn limiting slot, 100, long slot hole.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
It as shown in Figures 2 and 3, is the utility model optimum embodiment, a kind of intramedullary nail aiming set, including sleeve body 1,
The shape in 1 section of sleeve body is 8-shaped, has mutually independent upper through-hole 11 and lower through-hole 12, upper through-hole in sleeve body 1
11 are located in the upper semisection 8-shaped of sleeve body 1, and lower through-hole 12 is located in the lower semisection 8-shaped of sleeve body 1, upper through-hole 11
It is parallel to each other and is located among sleeve body 1 with the central axis of lower through-hole 12.The outer ring of the end of sleeve body 1 is provided with more
Limiting slot 13 is enclosed, multi-turn limiting slot 13 is continuously arranged in the outer ring of the end of sleeve body 1 and forms waveform.
Locking nail hole on intramedullary nail would generally be designed to long slot hole 100 (as shown in Figure 1), when its object is to perform the operation according to
The different demand of patient realizes static pressurization or dynamic pressurized, to realize that it is corresponding that this function needs to design on mating instrument
The intramedullary nail of elongated slot sighting device, the utility model aims at set and long slot hole 100 matches, mutually independent upper 11 He of through-hole
Lower through-hole 12 is directed at long slot hole 100 simultaneously, can accurately plant two intramedullary nails out of upper through-hole 11 and lower through-hole 12 respectively
Enter desired position, do not interfere with each other, and implantation process is reliable and stable, no shaking.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
