Abstract
The invention discloses a kind of caput femoris necrosis support stick convenient to remove, including：Polyether-ether-ketone support stick body, the lower end of the polyether-ether-ketone support stick body is provided with threaded connection section, the upper end of the polyether-ether-ketone support stick body is provided with mulberries shape supporting head part, the surface of the polyether-ether-ketone support stick body is provided with bone trabecula coating.Advantage is：Tantalum metal is substituted using polyether-ether-ketone polymeric material and carries out making production, can either reach with clinical efficacy as tantalum metal phase, production cost is greatly reduced again；Its modulus of elasticity can directly be cut close to bone tissue during taking-up, convenient to remove；Supporting head part uses mulberries shape profile, close to the inner surface configuration in caput femoris necrosis area, and increases the surface area contacted with bone trabecula；Support stick integral surface sets bone trabecula coating to greatly increase Bone Ingrowth probability, reaches the purpose of disease treatment.
Description
Technical field
The present invention relates to a kind of medicine equipment, more particularly to a kind of caput femoris necrosis support stick.
Background technology
With the development of medical services, requirement of the patient to medical assistant product also more and more higher, instantly caput femoris necrosis
Finish Post operation to increase porosity, promote femur head growth, patient needs to use support stick to be supported femoral head, it is former
All it is made of to use tantalum metal the support stick that uses, production cost is high, and hardness is high, it is impossible to cut, and takes out inconvenience, together
When, existing support stick Bone Ingrowth is undesirable, once slipping needs re-starts operation during support, there is safety hidden
Suffer from, can not meet the use requirement of patient.
The content of the invention
The technical problems to be solved by the invention are：A kind of caput femoris necrosis support stick convenient to remove is provided.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Caput femoris necrosis support stick, including：It is poly-
Ether ether ketone support stick body, threaded connection section is provided with the lower end of the polyether-ether-ketone support stick body, in the polyethers ether
The upper end of ketone support stick body is provided with mulberries shape supporting head part, and the surface of the polyether-ether-ketone support stick body is provided with bone
Girder coating.
In order to preferably solve above-mentioned technical problem, the further technical scheme that the present invention is used is：In the mulberries shape
Supporting head part is internally provided with a bit of wire that can develop under X-ray.
In order to preferably solve above-mentioned technical problem, the further technical scheme that the present invention is used is：Connect in the screw thread
The bottom for connecing section is provided with the plum blossom connected in star cooperated with quincunx bottle opener.
It is an advantage of the invention that：Above-mentioned caput femoris necrosis support stick, substitutes tantalum metal using polyether-ether-ketone polymeric material and enters
Row make production, can either reach with clinical efficacy as tantalum metal phase, production cost is greatly reduced again；Its modulus of elasticity connects
Nearly bone tissue, can directly be cut during taking-up, convenient to remove；Supporting head part uses mulberries shape profile, bad close to femoral head
The inner surface configuration in dead band, and increase the surface area contacted with bone trabecula；Support stick integral surface sets bone trabecula coating energy
Bone Ingrowth probability is enough greatly increased, the purpose of disease treatment is reached.
Brief description of the drawings
Fig. 1 is the structural representation of caput femoris necrosis support stick of the present invention.
Fig. 2 is the present invention looks up structural representation of threaded ends in Fig. 1.
In figure：1st, polyether-ether-ketone support stick body, 2, threaded connection section, 3, plum blossom connected in star, 4, mulberries shape supporting head part,
5th, wire, 6, bone trabecula coating.
Embodiment
The particular content of the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, caput femoris necrosis support stick, including：Polyether-ether-ketone support stick body 1, in the polyethers ether
The lower end of ketone support stick body 1 is provided with threaded connection section 2, and the upper end of the polyether-ether-ketone support stick body 1 is provided with mulberry
Shen shapes supporting head part 4, bone trabecula coating 6 is provided with the surface of the polyether-ether-ketone support stick body 1.
As shown in figure 1, the top for the ease of prompting caput femoris necrosis support stick enters depth in use, in institute
That states mulberries shape supporting head part 4 is internally provided with a bit of wire 5 that can develop under X-ray.
As shown in Fig. 2 in use for the ease of being screwed into caput femoris necrosis support stick using corresponding bottle opener, in institute
The bottom for stating threaded connection section 2 is provided with the plum blossom connected in star 3 cooperated with quincunx bottle opener, in actual application,
The hex-shaped recess cooperated with inner hexagon spanner can also be set in the bottom of the threaded connection section 2.
Above-mentioned caput femoris necrosis support stick, substitutes tantalum metal using polyether-ether-ketone polymeric material and carries out making production, can
Enough reach with clinical efficacy as tantalum metal phase, production cost is greatly reduced again；Its modulus of elasticity is close to bone tissue, during taking-up
Can directly it be cut, it is convenient to remove；Supporting head part uses mulberries shape profile, close to the inner surface shape in caput femoris necrosis area
Shape, and increase the surface area contacted with bone trabecula；It is long that support stick integral surface sets bone trabecula coating to greatly increase bone
Enter probability, reach the purpose of disease treatment.
