The present invention provides a kind of expansion marrow reamer, is used to carry out expansion marrow to femoral bone cavitas medullaris.Expanding marrow reamer can be used as hip joint
One of anterior approach instrument packet tool, with drag hook, hit handle device and Myelocavity file handle pulp cavity opener is used in conjunction with, complete hip
Joint anterior approach device.
Hereinafter, the structure of expansion marrow reamer of the invention is described in detail.
As shown in Figure 1, 2, 3, expansion marrow reamer of the invention includes blade 10, shank 20 and interconnecting piece 30.
Blade 10 includes the first noumenon 11 and the first connecting pin 12 positioned at 11 one end of the first noumenon, and the first noumenon 11 can
It protrudes into femoral bone cavitas medullaris, and the periphery of the first noumenon 11 has multiple expansion marrow slots.
Shank 20 include the second ontology 21 and the second connection end 22 positioned at 21 one end of the second ontology, the second ontology 21 it is another
One end can be connect with power mechanism (not shown).
Wherein, the first connecting pin 12 and second connection end 22 with the rotatable connection of interconnecting piece 30 so that 10 He of blade
Shank 20 being capable of relative rotation.
The present invention is will to expand marrow reamer to be divided into 20 two parts of blade 10 and shank, is carried out among the two by interconnecting piece 30
Connection, enables 20 relative rotation of blade 10 and shank.In surgical procedure, holds shank 20 and rotate, it can be as needed
The angle between shank 20 and blade 10 is adjusted, shank 20 can be connect with power mechanism, the rotation of blade 10 can be controlled, and
The angle between shank 20 and blade 10 can be adjusted while rotating.Whole process, the shank 20 and human body that reamer expands marrow are not
It interferes, and does not influence the use of power mechanism.
Compared with existing stock class integral type expands marrow reamer, between the blade 10 and shank 20 of expansion marrow reamer of the invention
Angle it is adjustable so that surgical procedure is convenient, save operating time.The present invention is that the minimally invasive of operation provides instrument guarantor
Barrier, clinical feedback effects are good.
In the present embodiment, interconnecting piece 30 is double universal coupling, and blade 10 and shank 20 is allowed to have bigger curvature.
The range of angle is between 100 degree -180 degree between blade 10 and shank 20.Such as shown in Fig. 2, between blade 10 and shank 20
Angle be about 100 degree.
Fig. 3 shows a variety of change locations, can be in angle, interconnecting piece 30 and the between interconnecting piece 30 and the first connecting pin 12
It can be in angle between two connecting pins 22.Therefore, the angle between blade 10 and shank 20 can flexible modulation, avoid and human body occur
Interference, influences surgical procedure.
As a shown in Figure 6, expanding marrow reamer may also include elastic mechanism 40, surround interconnecting piece 30, the first connecting pin 12 and
Second connection end 22 (elastic mechanism, which is not shown, in Fig. 1 surrounds the first connecting pin and interconnecting piece).As shown in Figure 1, blade 10 with
Angle is 180 degree between shank 20, i.e., blade 10 and shank 20 linearly, at this point, elastic mechanism 40 in the raw under.
When angle is less than 180 degree between blade 10 and shank 20, that is, relative rotation, when there is angle, elastic mechanism occur for the two
40 pairs of blades 10 surrounded and shank 20 apply elastic force, so that blade 10 and shank 20 have the trend straightened.Elastic mechanism
40 setting also provides constraint to the activity relatively of blade 10 and shank 20, prevents the excessively activity of blade 10 from losing position.Also,
Blade 10 and shank 20 are connected by interconnecting piece 30 and elastic mechanism 40, improves and finishes while guaranteeing flexibility
The globality of structure.
In the present embodiment, elastic mechanism 40 is to be interrupted double flat springs.Specifically, as shown in fig. 6, it may include two sections double
To twisting resistance spring 41 and the elastic joint part 42 being connected between two sections of two-way twisting resistance springs 41, two sections of two-way twisting resistance bullets
Spring 41 surrounds the first connecting pin 12 and second connection end 22 respectively, and elastic joint part 42 surrounds interconnecting piece 30.Therefore, elastic mechanism
The two-way twisting resistance spring 41 of two sections of 40 provides elasticity to the first connecting pin 12 and second connection end 22 respectively, guarantees two connection
Joint curvature number is essentially identical, provides constraint while guaranteeing flexibility.
In the present embodiment, as shown in Fig. 1,4, the first noumenon 11 is tapered, can be approximate with femoral bone cavitas medullaris vertebra degree.First
11 periphery of body is recessed with that first row cuts slot 13 and second row cuts slot 14, and first row is cut slot 13 and is set to along the axis of the first noumenon 11
The first noumenon 11 after first row cuts the molding of slot 13, forms second row along the hand of spiral around the periphery of the first noumenon 11 and cuts slot
14。
The quantity that first row cuts slot 13 can be multiple, and be uniformly distributed, and second row cuts slot 14 along the equidistant spiral of axis point
Cloth, and it is 1-3mm that second row, which cuts the radius of slot 14,.In the present embodiment, the quantity that first row cuts slot 13 is 5, and second row cuts slot
14 be three helixes, radius 2mm, so that in terms of end face, the substantially pentagon of the first noumenon 11.
Axial first row cuts slot 13 and spiral helicine second row cuts slot 14 and facilitates chip removal and cooling, also, spiral helicine
Second row, which cuts slot 14, can also reduce the contact area of reamer blade and sclerotin, reduce cutting force.
Form, the quantity that row cuts slot are without being limited thereto.For example, axial first row, which can only be arranged, cuts slot 13, can also only be arranged
Spiral helicine second row cuts slot 14.The quantity that first row cuts slot 13 can be 3.
In conclusion compared with existing stock class integral type expands marrow reamer, the blade and handle of expansion marrow reamer of the invention
Angle between portion is adjustable, so that surgical procedure is convenient, saves operating time.The present invention is that the minimally invasive of operation provides device
Tool guarantee, clinical feedback effects are good.
Although exemplary embodiment describes the present invention with reference to several, it is to be understood that, term used is explanation and shows
Example property, term and not restrictive.The spirit or reality that can be embodied in a variety of forms due to the present invention without departing from invention
Matter, it should therefore be appreciated that above-described embodiment is not limited to any of the foregoing details, and the spirit defined by appended claims
It all should be accompanying power with the whole change and modification widely explained, therefore fallen into claim or its equivalent scope in range
Benefit requires to be covered.
