Abstract
The invention discloses a kind of femoral interlocking nail inserting needle spot locators, including locator ontology, the locator body proximal end is equipped with the valgus angle of a 5-10 degree, distal end uses inclined-plane toothed design, bevel inclination angle is 60 degree, the whole circle in edge is provided with sawtooth, and the cross section of the locator ontology is equipped with the equally distributed location hole in 5-6 hole.The vertex of the valgus angle is in locator at remote 1/3.Guide pin is movably set in the inboard aperture and apertura lateralis.The present invention can correct the guide pin directionality problem hindered by alaossisilii, and locator is designed using porous and distal slope, and patient is made to have more entry point optimal locations, reduces damage of the touch system to sclerotin repeatedly, shorten operating time.The locator distal end toothed design simultaneously, prevents the sliding of locator during beating guide pin itself.
Description
Technical field
The present invention relates to medical instrument fields, and in particular to a kind of femoral interlocking nail inserting needle spot locator.
Background technique
In recent years, with the development of orthopaedic trauma treatment concept, four limbs tubular bone fracture application intramedullary nail treatment is had become
The goldstandard for the treatment of, the fixed theory of unique centrality embody especially pronounced in the advantage of lower limb.But intramedullary nail is being performed the operation
The determination of entry point in the process, especially guide pin squeeze into during because pelvis alaossisilii obstruction, make guide pin often from entry point
Small tuberosity direction is squeezed into, femoral bone cavitas medullaris cannot be correctly squeezed into, but for intramedullary nail operation, the importance of entry point is passed through always
Wear operation whole process.
Summary of the invention
To solve the above problems, can be provided more accurate the present invention provides a kind of femoral interlocking nail inserting needle spot locator
Entry point, positioned than existing common touch system, there is apparent advantage.
To achieve the above object, the technical scheme adopted by the invention is as follows:
Femoral interlocking nail inserting needle spot locator, including locator ontology, the locator body proximal end are equipped with a 5-10 degree
Valgus angle, distally use inclined-plane toothed design, bevel inclination angle be 60 degree, edge it is whole enclose be provided with sawtooth, the positioning
The cross section of device ontology is equipped with the equally distributed location hole in 5-6 hole.
Further, the vertex of the valgus angle remote 1/3 in locator at.
Further, guide pin is movably set in the inboard aperture and apertura lateralis.
Further, the locator ontology overall length about 15-20cm, diameter are about 2.0-2.5cm, and material is titanium conjunction
Gold.
Further, the quantity of the location hole is 5, one of them is arranged in the cross section of locator ontology 1
At the heart, other four location hole is uniformly distributed along the location hole at center.
The invention has the following advantages:
There are 5-10 degree valgus angle, specific angles to provide the elasticity modulus of pilot pin material by producer for locator of the invention
It determines, to correct the guide pin directionality problem hindered by alaossisilii, locator distal slope design, against big after Pyriform sinus appears
It is placed in guider on the inside of tuberosity vertex, squeezes into guide pin in locator inboard aperture, the entry point suitable for femur direct motion intramedullary nail is true
Recognize, similarly, squeezes into guide pin in the apertura lateralis of locator, positioning is basic just in the partially interior rear direction in femoral bone tuberosity vertex, this positioning
It is determined suitable for proximal femoral nail entry point.The locator distal end toothed design simultaneously, it is fixed during beating guide pin to prevent
The sliding of position device itself.The porous design of the locator makes patient have more entry point optimal locations, reduces touch system repeatedly
Operating time is shortened in damage to sclerotin.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of femoral interlocking nail of embodiment of the present invention inserting needle spot locator.
Specific embodiment
In order to which objects and advantages of the present invention are more clearly understood, the present invention is carried out with reference to embodiments further
It is described in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
As shown in Figure 1, the embodiment of the invention provides a kind of femoral interlocking nail (including femur direct motion intramedullary nail and femur it is close
Hold intramedullary nail) inserting needle spot locator, including locator ontology 1, valgus angle of 1 proximal end of locator ontology equipped with a 5-10 degree
2, distal end 3 uses inclined-plane toothed design, and bevel inclination angle is 60 degree, and the whole circle in edge is provided with sawtooth, the locator ontology 1
Cross section be equipped with the equally distributed location hole 4 in 5-6 hole.The vertex of the valgus angle 2 remote 1/3 in locator at.Institute
It states in inboard aperture and apertura lateralis and is movably set with guide pin.1 overall length of the locator ontology about 15-20cm, diameter are about
2.0-2.5cm, material are titanium alloy.
Preferably, the quantity of the location hole is 5, and the center of the cross section of locator ontology 1 is arranged in one of them
Place, other four location hole are uniformly distributed along the location hole at center.
This specific implementation appears musculature, it is close to appear femur for muscle of riving in use, incision skin and subcutaneous tissue
Pyriform sinus on the inside of section greater trochanter, the then implantation on the inside of greater trochanter vertex by locator, is touched with bone hammer, makes distal end dentation knot
Structure is pierced into sclerotin, is ready for pilot pin and squeezes into, and at least 2-3 pieces.It is fixed as final entry point to have an X-rayed one piece for selecting position good
Position needle pulls out locator, routine operation operation implantation intramedullary nail.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
