Abstract

This utility model relates to the field of traction frame technology and discloses an adjustable bone traction frame, comprising: a puncture needle with a U-shaped rod on its outer side wall; a fixing component below the U-shaped rod, the fixing component comprising: an L-shaped plate at the bottom of the U-shaped rod; a strap on the outer side wall of the L-shaped plate; a spring on one side of the L-shaped plate; a push plate at one end of the spring; and a U-shaped plate at the top of the push plate. This bone traction frame, through the fixing component, uses the spring to push the push plate to move, simultaneously driving the U-shaped plate to pull the U-shaped rod to move and apply traction to the patient. During treatment, there is no rope friction against the patient's skin, improving patient comfort. The bone traction frame, through the adjusting component, uses the rotation of bolts to adjust the position of the moving plate. During movement, the moving plate compresses the spring, thereby increasing the spring's rebound force and increasing the traction force.

In the related art, a conventional bone traction device is generally pulled by connecting a gravity sand bag through a rope after a traction needle is fixed by a traction bow. However, this approach has a problem in that the rope is rough and easily rubs the instep or toe head when the rope is pulled downward, giving a patient uncomfortable feeling.

To solve the problems in the related art to a certain extent, the embodiment of the application provides an adjustable bone traction frame, when the adjustable bone traction frame needs to be installed, a puncture needle 11 is firstly penetrated through the tibia of a patient, then two ends of a U-shaped rod 12 are connected with the puncture needle 11, then an L-shaped plate 21 is placed under the calf of the patient and is bound and fixed through a binding belt 22, then one end of the U-shaped rod 12 is lapped inside a U-shaped plate 25 by rotating the U-shaped rod 12, at the moment, a spring 23 rebounds to push a push plate 24 to move, and the push plate 24 drives the U-shaped plate 25 to move so as to pull the puncture needle, thereby treating the patient. The skin of the patient is not rubbed during the treatment process, which causes discomfort to the patient. When the traction force of the U-shaped rod 12 needs to be adjusted, the threaded rod 33 can be rotated, the threaded rod 33 can be contacted with the moving plate 31 during rotation, so that the moving plate 31 is driven to move to one side, the spring 23 is pushed to be compressed during movement, the rebound force of the spring 23 is increased, and the push plate 24 is pushed to move better to adjust the traction force of the U-shaped rod 12.

The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

Referring to fig. 1-4, an embodiment of the application provides an adjustable bone traction frame, which comprises a U-shaped rod 12 rotatably arranged on the outer side wall of a puncture needle 11, a fixing component 2 arranged below the U-shaped rod 12, wherein the fixing component 2 comprises an L-shaped plate 21 arranged at the bottom of the U-shaped rod 12, a binding belt 22 fixedly arranged on the outer side wall of the L-shaped plate 21, a spring 23 arranged on one side of the L-shaped plate 21, a push plate 24 arranged on one end of the spring 23, and a U-shaped plate 25 arranged on the top of the push plate 24.

Specifically, the surface of the binding band 22 is provided with a velcro to fix the patient's lower leg to the L-shaped plate 21 by adhesion. The tibia transverse bone movement principle mainly comes from a physiological phenomenon discovered by irizalov. The doctor found that by pulling on cortical bone, or after a certain osteotomy of bone and pulling, blood vessels, nerves and other soft tissue structures within the body were grown. Even without obvious attachment relationships, after such osteotomies, distraction procedures are performed, there is a significant increase in surrounding growth factors, such as vascular endothelial growth factor, which promote repair of surrounding soft tissue. Therefore, based on the principle, after the tibia transverse bone moving operation is performed, the blood circulation reconstruction of the lower limb can be promoted in the process.

When the puncture needle is required to be installed in use, the puncture needle 11 is firstly penetrated through the tibia of a patient, then the two ends of the U-shaped rod 12 are connected with the puncture needle 11, then the L-shaped plate 21 is placed under the calf of the patient, the U-shaped rod 12 is bound and fixed through the binding belt 22, then one end of the U-shaped rod 12 is lapped in the U-shaped plate 25 by rotating the U-shaped rod 12, at the moment, the spring 23 rebounds to push the push plate 24 to move, and the push plate 24 drives the U-shaped plate 25 to move so as to pull the puncture needle, thereby treating the patient. The skin of the patient is not rubbed during the treatment process, which causes discomfort to the patient.

In some embodiments, the U-shaped rod 12 is of a telescopic structure, and an adjusting bolt is arranged on the surface of the U-shaped rod 12 to adjust the length of the U-shaped rod.

When in use, the U-shaped rod 12 is of a telescopic structure, the length of the legs can be different according to the height of a patient, and the length of the U-shaped rod 12 can be adjusted by rotating the adjusting bolt according to the needs of the patient.

In some embodiments, the securing assembly 2 further includes a cross bar 26 having one end connected to the L-shaped plate 21 through the push plate 24.

The design of the cross bar 26 can make the push plate 24 move stably during use, and limit the moving track of the push plate 24 so that the push plate is not easy to deviate.

In some embodiments, the securing assembly 2 further includes a baffle 27 disposed at one end of the rail 26.

In use, the push plate 24 is restrained from disengaging the crossbar 26 during movement of the push plate 24.

In some embodiments, the securing assembly 2 further includes an arcuate plate 28 disposed on top of the L-shaped plate 21.

The design of the curved plate 28 in use can be such that the curved plate 28 can hold the patient's lower leg when the patient places the leg on the L-shaped plate 21, improving comfort.

In some embodiments, the push plate 24 is provided with an adjusting assembly 3, and the adjusting assembly 3 includes a moving plate 31 penetrated by the cross bar 26 and connected to the spring 23 at one side, a hole 32 formed on an outer side wall of the push plate 24, and a threaded rod 33 having one end penetrating the hole 32 and the moving plate 31 and rotatably connected to the L-shaped plate 21 and screwed to the moving plate 31.

When the traction force of the U-shaped rod 12 needs to be adjusted in use, the threaded rod 33 can be rotated, the threaded rod 33 can be contacted with the movable plate 31 during rotation, so that the movable plate 31 is driven to move to one side, the spring 23 is pushed to be compressed in the moving process, the rebound force of the spring 23 is increased, and the push plate 24 is pushed to move better to adjust the traction force of the U-shaped rod 12.

In some embodiments, the spring 23 is sleeved outside the threaded rod 33.

The design of the spring 23 sleeving in use can ensure that the limit spring 23 with the threaded rod 33 can not bend while the spring 23 is compressed, thereby better protecting the spring 23.

In some embodiments, the adjustment assembly 3 further comprises a knob 34 disposed at one end of the threaded rod 33.

The setting of the turn knob 34 is convenient when using to grasp the rotation of control threaded rod 33, and simultaneously the recess on turn knob 34 surface can increase frictional force when rotating thereby the difficult condition that slips appears in the rotation.

In the description of the present specification, a description referring to the terms "one embodiment," "some embodiments," "examples," "particular examples," "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present application. In this specification, schematic representations of the above terms are not necessarily directed to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, one skilled in the art can combine and combine the different embodiments or examples described in this specification.
