Fig. 1-6 is please referred to, the utility model provides a kind of technical solution:
A kind of orthopaedics nail accommodation tube, including outer cylinder 1, inner cylinder 2 and cover 3, the outer cylinder 1 and inner cylinder 2 can be used stainless
There is the cylinder of opening, for the ease of carrying, taking and anticorrosion, outside the present embodiment made of steel thin slice, iron plate or PVC material
Cylinder 1, inner cylinder 2 are made of stainless steel thin slice.
The inner cylinder 2 is mounted in outer cylinder 1, and the bottom of the inner cylinder 2 and non-return mechanism 12 are rotatablely connected, along inner cylinder 2
Circumferencial direction be equipped with several groups screw accommodating groove 21,21 particular number of screw accommodating groove flexibly sets depending on particular condition in use,
The slot of the concave shape of the screw accommodating groove 21；For screw 4 by taking os integumentale screw as an example, length is generally 8-40mm, and diameter is
3.5mm, so the diameter of screw accommodating groove 21 is more than or equal to 4 diameter of screw, in order to which screw 4 is preferably put into screw accommodating groove
21,21 diameter of the present embodiment screw accommodating groove is 1.2-1.4 times of 4 diameter of screw, the flute length of 21 slot of screw accommodating groove greater than etc.
In the length of screw 4, this implementation uses the flute length of screw accommodating groove 21 for 1.2-1.4 times of length of screw 4, and 2 length of inner cylinder is small
In equal to 1 length of outer cylinder.
The barrel of the outer cylinder 1 offers one along its axial direction and takes nail mouth 10, and the bottom in outer cylinder 1 is equipped with only
Go back to mechanism 12；The non-return mechanism 12 includes ratchet 13, axis 14 and the pawl 15 with spring, in which: the axis 14 is fixed on
Bottom in outer cylinder 1, on axis 14, the pawl 15 contacts 13 turning set of ratchet with ratchet 13；Bottom in the inner cylinder 2
Bar I 20 is vertically installed at the center in portion, the top of the bar I 20 offers square groove 22, and the bottom of the bar I 20 is through interior
The bottom of cylinder 2 is fixedly connected with ratchet 13, and ratchet 13, axis 14 and the pawl 15 with spring constitute ratchet mechanism, because of bullet
Spring forces pawl 15 and ratchet 13 with stopping function to be kept in contact, so when inner cylinder 2 rotates, it can only be according to such as Fig. 1 arrow
One direction of head moves and cannot invert, and ensure that doctor can take nail in order, while guaranteeing when not taking nail, inner cylinder 2
It does not rotate with outer cylinder 1, avoids the abrasion that 2 screw of inner cylinder does not shake and generates, in use, when any one screw is stored
Slot 21, which rotates to, takes nail mouth 10, the screw 4 in it can be taken out.
The cover 3 is mounted at the top entry of outer cylinder 1, and the cover 3 is equipped with rotating mechanism, the rotating mechanism with

In reserved axis hole, the bar II 30 is sleeved on the top of circular discs 31, and the bottom end of the bar II 30 is square protrusion 32, described
Square protruding 32 is plugged in square groove 22, and cover 3 is covered outer cylinder 1, inner cylinder 2 to be made in circular discs 31 by rotating circular discs 31
Square protruding 32 drive the bar I 20 of its grafting, the bar I 20 drives entire inner cylinder 2 to rotate, when any one screw accommodating groove
21 rotate to take nail mouth 10, can by the screw 4 in it take out for surgical use.
Embedded with the spill magnet block 23 to match with cell wall, the effect of spill magnet block 23 one in the screw accommodating groove 21
It is in order to keep screw 4 stronger (process including rotation) in screw accommodating groove 21, second is that when the arrival of screw 4 takes nail mouth 10
Shi Buhui falls out, doctor by hold tweezers or hand strap sterile glove apply the power of a very little and can be taken off screw 4.
It is hinged on the outer cylinder 1 taken at nail mouth 10 for covering the capping 11 for taking nail mouth 10, not by taking nail mouth
10 take can be closed when nail take nail mouth 10, prevent screw 4 from falling.
In use, first opening cover 3, the screw 4 after disinfection is inserted into screw accommodating groove 21, screw storage
After slot 21 is all stuck with, cover 3 is covered at the top entry of outer cylinder 1,3 bottom of cover is just and at the top entry of outer cylinder 1
It being in contact, square protruding 32 drives the bar I 20 of its grafting, and drive entire inner cylinder 2 to rotate by rotation 31 bar I 20 of circular discs, when
Any one screw accommodating groove 21, which rotates to, takes nail mouth 10, the screw 4 in it can be taken out and be used for surgical, performed the operation
After, nail mouth 10 is not taken by taking nail mouth 10 to take to close when nail, prevents screw 4 from falling.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
