Description

Expandable self-stabilizing sacroiliac joint surgery endoscopic device

Technical Field

The utility model relates to an endoscope device, in particular to an expansion self-stabilizing sacroiliac joint surgery endoscope device.

Background Art

The sacroiliac joint is the joint that connects the spine to the pelvis. It is a micro-motion semi-synovial joint. The front 1/3 is a true synovial joint, and the back is a muscle-ligament complex. Sacroiliac joint pain is one of the important sources of chronic low back and leg pain. Sacroiliac joint pain refers to pain in and near the sacroiliac joint that can be induced by local pressure and sacroiliac joint induction tests. It mainly occurs in the buttocks, posterior and lateral thighs, and waist. Some patients will experience groin area, back, and abdomen. Most patients experience pain above the knee joint, and a few patients will radiate to below the knee joint.

Endoscopic surgery is used during the treatment of sacroiliac joint pain. During the operation, an assistant is required to hold the endoscope for positioning. Existing endoscopes have the following problems during use: 1. The positioning components attached to them are not suitable for the sacroiliac joint, which has a special structure, and are prone to slippage. 2. They cannot be accurately positioned, making it inconvenient to accurately guide the insertion of internal fixation devices. 3. One person is always required to hold the endoscope, which wastes manpower and may cause unnecessary displacement.

DETAILED DESCRIPTION

The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

As shown in Figures 1 to 2, the expansion self-stabilizing sacroiliac joint surgical endoscopic device includes an end expansion device, which is different in that the end expansion device is provided with an endoscope device through a connecting component. At the same time, considering the convenience of operation, an aiming component is also provided on the connecting component. In order to achieve convenient positioning, the end expansion device can be firmly combined with the sacroiliac joint gap. The end expansion device used in the utility model includes an outer sleeve 1, in which an inner threaded rod 2 is provided with a threaded connection, and the lower end of the inner threaded rod 2 is provided with a spiked end 3. In this way, the spiked end 3 can be inserted into the sacroiliac joint gap, so that the front end of the inner threaded rod 2 can be squeezed with the sacrum and ilium on both sides of the sacroiliac joint to ensure that the entire device does not have unnecessary displacement. In addition, considering the need for operational locking, after the inner threaded rod 2 reaches a suitable squeezing position, continuous force can be achieved. An elastic component 4 is sleeved on the inner threaded rod 2, and a displacement adjustment component is provided at the upper end of the inner threaded rod 2. Therefore, the elastic component 4 can be controlled by the displacement adjustment component, thereby providing effective squeezing force to achieve force retention.

In combination with a preferred embodiment of the utility model, in order to achieve an integrated layout, the connecting component used includes a connecting plate 5, on which a main accommodating hole and a secondary accommodating hole are respectively provided, an end expansion device is provided in the main accommodating hole, and an endoscope device is provided in the secondary accommodating hole.

Further, considering the convenience of use, the aiming assembly includes an extension plate 6 connected to the connecting assembly. Specifically, a limit hole is provided on the extension plate 6, a height adjustment rod 7 is provided in the limit hole, a through adjustment hole is provided at the side end of the limit hole, and a locking knob 8 is inserted into the through adjustment hole. In this way, the height adjustment rod 7 can be freely adjusted up and down in the free stroke state. When the lower end of the height adjustment rod 7 contacts the sacroiliac joint gap or reaches the position required for positioning, the locking button is rotated and locking can be achieved through appropriate lateral extrusion force. At the same time, a guide tube 18 is provided at the bottom of the height adjustment rod 7. In this way, the guide tube 18 can be used to embed into the sacroiliac joint gap to achieve effective auxiliary positioning. In addition, in order to meet the needs of convenient combination and separation, a connecting groove 17 is provided on one side of the connecting assembly, and a tenon 9 is extended from the side end of the extension plate 6, and the tenon 9 is inserted into the connecting groove 17. Furthermore, in order to effectively connect and lock, the connecting groove 17 and the tenon 9 are both provided with locking holes corresponding to the position, and a locking bolt 11 is inserted into the locking hole.

In view of the actual implementation, in order to satisfy the continuous force application of the elastic component 4, the elastic component 4 is a spring. At the same time, in order to avoid certain stress impact caused by the release of the spring during use, silicone buffer rings can be provided at both ends of the spring.

Further, for the convenience of operation, the displacement adjustment assembly includes a limiting boss 12 arranged at the upper end of the outer sleeve 1, and an adjustment nut 13 is arranged at the upper end of the internal threaded rod 2. Thus, by loosening the adjustment nut 13, the up and down displacement adjustment of the internal threaded rod 2 can be achieved. When it is in a suitable position, tightening the adjustment nut 13 can achieve the locking of the internal threaded rod 2.

During use, the lower end of the outer sleeve 1 is provided with a plurality of deformation grooves 14. In this way, when the spike tip 3 is extended, a certain expansion deformation is achieved, so that the spike tip 3 can be extended smoothly without getting stuck. At the same time, the endoscope device includes a sheath tube 15, and an endoscope body 16 is arranged in the sheath tube 15. In this way, the endoscope body 16 can be prevented from getting stuck when contacting with tissues, and the endoscope body 16 has a space for free rotation.

The working principle of the utility model is as follows:

The outer sleeve 1 is pressed against the outside of the tissue. Then, the displacement adjustment component is loosened, and the internal threaded rod 2 is rotated to insert the spiked end 3 at the front end into the sacroiliac joint space. With the continuous insertion of the spiked end 3, the sacrum and ilium on both sides of the sacroiliac joint are squeezed. Then, the displacement adjustment component is locked.

At the same time, the front end of the sheath tube 15 just contacts the bone of the sacroiliac joint surface to play a limiting role.

Next, the height adjustment rod 7 is adjusted so that the guide tube 18 at the lower end thereof is embedded in the sacroiliac joint space to achieve effective auxiliary positioning. Then the height adjustment rod 7 is locked to achieve overall aiming and locking.

During use, the endoscope body 16 can rotate freely, observation is not restricted, and no personnel support is required, so that independent operation by a single person can be achieved.

It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

1. The device can be stably combined with the sacroiliac joint space through expansion combination to ensure that it will not fall off easily within the appropriate force application range.

2. It can be operated by one person and is easy to use.

3. The endoscope has a free observation space, which is convenient for surgical observation and operation.

4. An aiming component can be added to achieve further auxiliary positioning and facilitate sacroiliac joint fusion.

5. The overall structure is simple, easy to manufacture and use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
