Description

Universal connector

Technical Field

The utility model mainly relates to the field of medical instruments, in particular to a universal connector.

Background

In a pedicle screw rod system for spinal fixation, a spinal connecting rod is used for maintaining the curvature of the spine, and in some cases, the fixed spinal connecting rod needs to be extended again to increase the fixation range, so that a connector is needed to increase the length of the spinal connecting rod.

Traditional connector is for enclosing the structure entirely, need penetrate from the one end of connecting rod during the installation, needs bigger operation space in clinical to it is great to lead to human wound, and the operation time is longer. The relative position of the connecting rod is fixed after installation, the direction and the angle of the connecting rod cannot be adjusted, the connecting mode is single, and therefore the application range is limited, and the operation effect is affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model provides the universal connector which is simple in structure, convenient to use, high in flexibility and installation convenience due to the adoption of a universal connecting structure, firm in fixing of the connecting rod, high in safety performance, capable of being stably held and taken, convenient to operate, anti-falling performance of the clamping ring and convenient to install.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

the utility model provides a universal connector, includes universal seat, spherical ring, fixing base, jackscrew and connecting rod, be provided with the bulb on the fixing base, set up a ball hole and two on the spherical ring and prop the fluting, the ball hole scope has surpassed half sphere, universal seat, fixing base pass through the jackscrew respectively with connecting rod fixed connection.

Furthermore, a funnel is arranged in the feeding hole.

Furthermore, the funnel is fixedly connected with the inner wall of the feeding hole.

Furthermore, the bottom end of the vertical rod is rotatably connected with the bottom surface inside the box body through a bearing.

Compared with the prior art, the utility model has the beneficial effects that:

the clamp ring is simple in structure, convenient to use, high in flexibility, convenient to install, firm in fixing of the connecting rod, high in safety performance, capable of being stably held and taken, convenient to operate, anti-falling performance of the clamp ring and convenient to install.

Detailed Description

The utility model is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications can be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

As shown in fig. 1-4, the universal connector of the present invention includes a universal base 1, a spherical ring 2, a fixed base 3, a jackscrew 4 and a connecting rod, wherein a ball head is disposed on the fixed base 3, a ball hole and two supporting slots are disposed on the spherical ring 2, the range of the ball hole exceeds a half sphere, and the universal base 1 and the fixed base 3 are both fixedly connected to the connecting rod through the jackscrew 4.

Specifically, the fixed seat 3 is provided with an arc surface of a semi-enclosed structure. The arc surface of the semi-surrounding structure is arranged on the fixing seat 3, so that the connecting rod can be effectively fixed and can not be separated.

Specifically, a holding groove structure is arranged on the fixed seat 3. The fixing seat 3 is provided with a holding groove structure which can be stably held by a tool and is convenient for operation

Specifically, two symmetrical protrusions are arranged on the spherical ring 2. Two symmetrical bulges are arranged on the spherical ring 2, and the spherical ring can be prevented from being separated when screwed into a groove on the universal seat 1.

Example (b):

when using this device, at first put into spherical ring 2 in universal seat 1, have sufficient space in the universal seat 1 and can make spherical ring 2 strut, press spherical ring 2 with the bulb on the fixing base 3 in, utilize taper fit to make spherical ring 2 in universal seat 1 after kick-backing, can, press more tightly, guarantee that the bulb does not deviate from, nevertheless can keep universal seat 1 for 3 universal rotations of fixing base before compressing tightly, reuse jackscrew 4 is with universal seat 1, fixing base 3 is fixed with the connecting rod respectively, reach the function of two connecting rods of universal connection, the diameter can be selected with the specification of interval, the connecting rod of the different specifications of adaptation.

The clamp ring is simple in structure, convenient to use, high in flexibility, convenient to install, firm in fixing of the connecting rod, high in safety performance, capable of being stably held and taken, convenient to operate, anti-falling performance of the clamp ring and convenient to install.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments can be modified or some technical features can be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
