And lock anti-moving bit architecture 5.Wherein, the material of the first noumenon 51 and the second ontology 52 can be hard plastics or rubber material
Expect, is preferably hard plastics in the present embodiment.Clinically since pull needle 1 is inserted into the depth difference or U of patient's lower limb 6
The position that type traction bow 2 is installed is different, may an end of U-shaped 2 open side of traction bow directly contacted with limbs of patient and another
One there are certain gaps between end and limbs of patient, therefore, in this case only need to be there are the installations of the one end in gap
The purpose for preventing pull needle 1 from shifting can be realized in anti-moving bit architecture 5.It is removable by the way that anti-moving bit architecture 5 to be arranged to pull needle 1
Connection is unloaded, patient's pull needle 1 during turn, activity etc. is effectively prevented and is displaced, reduce patient in Bone traction
Treat the middle danger infected；It, only need to be by anti-moving bit architecture 5 from pull needle 1 after the traction therapy of bone to patient terminates
On unload, then the other structures of bone distraction apparatus are successively removed；The structure is easy to use, can effectively make up the prior art
Deficiency.
Preferably, the contact surface that the anti-moving bit architecture 5 contacts side with patient's lower limb 6 is set to the song of rounding off
Face effectively reduces the risk that 6 wound of patient's lower limb was scratched or rubbed wound by anti-moving bit architecture 5.
It is further preferred that Anti-stabbing rubber plug 4 is arranged at 1 both ends of pull needle, it is effectively reduced and stabs patient or doctor
Business personnel skin or the risk for scratching patient's bedding, in addition, being provided with hanging ring 21, the hanging ring 21 on the U-shaped traction bow 2
Positioned at U-shaped traction bow 2U mouthfuls of the position of center line；Hanging ring 21 is arranged on U-shaped traction bow 2 to be used in traction therapy of bone
Traction rope is connected, hanging ring 21, which is set to U-shaped traction bow 2U mouthfuls of position of center line and is beneficial to prevent U-shaped traction bow 2, to shift
Influence therapeutic effect.
Clinically, a kind of anti-displacement lower-limb skeletal traction device provided by the present embodiment is also needed by traction rope, cunning
The sliding weight of steelyard of wheel and constant weight is just able to achieve the traction therapy of bone to patient, complete installation process are as follows: (1) by pull needle 1
Insertion patient need to draw the sclerotin of limbs, pass through sclerotin and protrude from opposite side skin, skin is covered with ethyl alcohol yarn block at pin hole；(2)
U-shaped traction bow 2 is installed in pull needle 1；(3) check is between limbs of patient and two ends of 2 open side of U-shaped traction bow
It is no that there are gaps；(4) there are the positions in gap to install anti-moving bit architecture 5；(5) Anti-stabbing is installed in 1 two ends of pull needle
Rubber plug 4；(6) traction rope is connected by the hanging ring 21 of U-shaped traction bow 2；(7) other end of traction rope is connected into patient's weight
The sliding weight of steelyard of weight, and hang and be fixed on pulley.Clinically bone distraction apparatus can be completed through the above steps
Installation, and then traction therapy of bone is carried out to patient.
Embodiment 2
It is as Figure 4-Figure 6 a kind of anti-displacement lower-limb skeletal traction device provided by the utility model, the present embodiment and reality
The difference for applying example 1 is that the specific structure of the anti-moving bit architecture 5 is different, the first of anti-moving bit architecture 5 in the present embodiment
Body 51 and the second ontology 52 are long strip shape structure, use steel plate structure in the present embodiment.It is set on the first noumenon 51
It is equipped with the protrusion of multiple spaced sets, is provided with that identical as the raised quantity and position is corresponding on second ontology 52
Groove, the first noumenon 51 can be cooperatively connected by the protrusion with the groove that is arranged on second ontology 52.Such as figure
It is the structural schematic diagram of one of connection type of the first noumenon 51 and the second ontology 52 described in 5-6, can passes through and adjust first
Ontology 51 is overlapped length with the second ontology 52 to realize the length for adjusting entire anti-moving bit architecture 5, and then realizes according to trouble
Anti-moving bit architecture 5 is adjusted to corresponding length by the length in the gap between the end of 2 open side of person's limbs and U-shaped traction bow, with
Realization withstands on anti-moving bit architecture 5 just between the end of 2 open side of limbs of patient and U-shaped traction bow, improves anti-moving bit architecture 5
Anti-displacement effect.
Preferably, the anti-moving bit architecture 5 contacts side with patient's lower limb 6 and is provided with elastic backing 7, which can
Circular sheet-like structures are made for rubber material, an end of elastic backing 7 and the second ontology 52 is fixed in the present embodiment connects
It connects.By the way that elastic backing 7 is arranged, effectively prevents the second ontology 52 i.e. steel plate and directly contacted with limbs of patient, suffered from reducing
The risk that person is stabbed by anti-moving bit architecture 5.As shown in figure 5, the through-hole is set to inside the first noumenon 51, the present embodiment
The installation process of middle anti-displacement device are as follows: medical staff first observes between the end of 2 open side of limbs of patient and U-shaped traction bow
Then the length in gap determines the position that the first noumenon 51 is connect with the second ontology 52, then pull needle 1 is embedded in the first noumenon 51
Through-hole inside, then the second ontology 52 is buckled in 51 corresponding position of the first noumenon, to realize the installation of anti-displacement device.
The other structures of 2 anti-displacement lower-limb skeletal traction device of the present embodiment are identical as embodiment 1, no longer go to live in the household of one's in-laws on getting married herein
It states.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
