It connects and is fixed in the middle part of the connection screw thread slot of female cone locked joints.Hair can be made using the connection mode of welding over the course for the treatment of
Bright overall structure is more stable.
As optimization of the present invention to said program, a diameter of 3~4mm of sheath.For the ease of therapeutic process mesotheca
Pipe gos deep into focal zone, and sheath pipe diameter should not be too large, and crossing conference makes that the medicament residual quantity of injection is excessive, and sheath pipe diameter also should not mistake
It is small, it is too small can cause instrument insufficient strength it is big, there is malpractice.
As optimization of the present invention to said program, the puncture tapered syringe needle in guid needle front end, and the taper pin
The connection of head R angles punctures guid needle side.The design that this kind punctures guid needle can be ensured that its hardness, toughness and puncture force meet stock
The requirement of bone puncturing operation.
As optimization of the present invention to said program, the guid needle material of puncturing is the stainless steel material after quenched.
The intensity of instrument can be further improved using quenched stainless steel material.
The beneficial effects of the present invention are：The present invention according to according to during caput femoris necrosis disease treatment, it is necessary to will be thicker
Bone tissue growth agent be injected into femoral head intramedullary, utilize the combination of sheath assembly and guid needle assembly, sheath pipe end is circumferential
Bone tissue growth agent uniformly can be penetrated into focal zone by the side opening of distribution, while the knife edge structure of sheath pipe end is when medical care is injected
When needing adjustment injection depth when injecting, can with help sheath be advanced to focal zone, guid needle assembly can be pushed away in sheath
It is more easily punctured on the basis of and injection.Therefore, this kind of structure can help sufferer that starting for large area is avoided to control
The drug-injection in treatment completed to femoral head is treated, so as to reduce the pain of sufferer and healing time.In addition, the present invention also has structure letter
List is easy to the characteristics of healthcare givers's operation.

Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, with reference to
Specific embodiment, the present invention is further explained.
A kind of femoral head puncture gate apparatus as shown in Figures 1 to 4, including sheath assembly and guid needle assembly,
Wherein, the sheath assembly is welded to form by sheath 2 and hollow female cone locked joints 3, and 2 end of sheath is equipped with tooth
Shape knife edge structure 8,2 end profile of sheath are circumferentially with anti-blocking infiltration hole 7, and the head end of the female cone locked joints 3 is screw thread
Connecting pin 6,3 end of inner circle taper joint weld and connect 2 front end of sheath, and the guid needle assembly includes puncturing guid needle
1st, outer cone locked joints 5 and connecting pole 4,5 end of outer cone locked joints are equipped with and the female cone locked joints 3
The adaptable connection screw thread slot 9 of threaded ends 6, and 9 middle part of connection screw thread slot is equipped with connecting pole 4, the connecting pole 4 connects institute
It states and punctures guid needle 1, and the connecting pole 4 and the hollow structure of female cone locked joints 3 are adapted, the puncture guid needle 1
It is adapted with the internal cavities of sheath 2.
In this example, the female cone locked joints 3 and outer cone locked joints 5 are standard luer fittings.Standard
Female Luer has wider applicability and compatibility in terms of medical supplies, improves the simplicity of the present invention.
In this example, described 4 one end of connecting pole, which is welded to connect, punctures guid needle 1, and the other end is weldingly fixed on female cone
9 middle part of connection screw thread slot of locked joints 3.The overall structure of invention can be made using the connection mode of welding over the course for the treatment of
It is more stable.
In this example, 2 a diameter of 3mm or 4mm of sheath.Go deep into focal zone for the ease of sheath in therapeutic process 2,
2 diameter of sheath should not be too large, and crossing conference makes the medicament residual quantity of injection excessive, and 2 diameter of sheath is also unsuitable too small, too small to cause
The insufficient strength of instrument is big, malpractice occurs.
In this example, the puncture tapered syringe needle in 1 front end of guid needle, and tapered needle R angles connection is punctured and led
1 side of draw pin.The design that this kind punctures guid needle 1 can be ensured that its hardness, toughness and puncture force meet femoral head puncturing operation
Requirement.
In this example, guid needle 1 material of puncturing is the stainless steel material after quenched.Using quenched stainless
Steel material can further improve the intensity of instrument.
Based on above-mentioned：According to according to during caput femoris necrosis disease treatment, it is necessary to which thicker bone tissue growth agent is injected into
In femoral head intramedullary, using the combination of sheath assembly and guid needle assembly, the circumferentially distributed side opening in 2 end of sheath can be uniform
Bone tissue growth agent is penetrated into focal zone, while the dentation knife edge structure 8 of 2 end of sheath needs adjustment to inject when medical care is injected
When being injected during depth, can with help sheath 2 be advanced to focal zone, guid needle assembly can be on the basis of the propulsion of sheath 2
It is more easily punctured and injection.Therefore, the treatment of starting that this kind of structure can help sufferer to avoid large area is completed to stock
The drug-injection in treatment of bone, so as to reduce the pain of sufferer and healing time.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in scope of the presently claimed invention.
