Description
Technical Field
The utility model relates to a unilateral binary channels scope technical field, concretely relates to supplementary interbody fusion cage of unilateral binary channels scope technique puts into sleeve pipe drag hook.
Background
Lumbar degenerative changes are common in the outpatient clinic of spinal surgery. At present, the spine minimally invasive endoscope technology relieves the pain of patients with minimal trauma, and develops more and more mature. In particular, the single-channel transforaminal endoscopic technique is rapidly popularized nationwide. However, due to the single channel, the flexibility and mobility during surgery is poor. The range of the surgical field is greatly limited, and in addition, the single-channel endoscope must be equipped with instruments with small size, which is specially made, and the efficiency of treating the lesion is low due to the slender size. Thus, the single pass transforaminal spine offers certain advantages in the management of simple cases of lumbar disc herniation. However, the technique is not satisfactory for complex cases such as lumbar spinal stenosis and unstable lumbar;
in order to overcome the defect, a single-side double-channel technology appears on the market; the single-side double-channel endoscope technology adopts two channels; one channel is an observation channel and is inserted with a 4mm endoscope, and the other channel is an operation channel, and spine surgical instruments with traditional sizes, such as rongeurs, curettes, abrasive drills and the like, can be adopted; the endoscope with the diameter of 4mm has good flexibility and mobility. The efficiency of treating the lesion is greatly enhanced with the conventionally sized instruments. The technique is therefore adequate for treating spinal complex cases of stenosis and instability, and even revision. The damage to normal soft tissue and bony results is small; the spine endoscope technology is another spine endoscope technology with high efficiency and good effect, the technology is developed in China for a few times, and the advantages that the efficiency of the technology is ensured are as follows: 1. clear observation visual field; 2. the depth of the intervertebral space is conveniently limited; 3. setting a proper intervertebral fusion device placing direction; 4. the intervertebral fusion cage is implanted smoothly; 5. tissue nerves around the wound are not affected; 6. the working space of the surgical instrument is ensured; 7. simple structure, few parts and simplified working steps.
The Chinese intellectual property office discloses an invention patent with application number CN201810731229.0, which comprises a tube body, wherein one end of the tube body is provided with a tube tongue, the other end of the tube body is provided with a handle, the tube tongue is provided with an arc-shaped protective sheath, the arc-shaped protective sheath is provided with an opening, in the operation process, after a guide pin punctures in place, the opening on the arc-shaped protective sheath can be matched with the guide pin and moves along the guide pin to reach the operation part, then the arc-shaped protective sheath moves to the lower part of the articular process to effectively wrap the articular process and separate soft tissues below the articular process; the invention utilizes the guide pin to penetrate the opening position of the arc-shaped protective sheath to play a role in guiding the moving direction, then utilizes the arc-shaped protective sheath to wrap the articular process, and achieves the purpose of separating the articular process from soft tissues at the corresponding position, the structure is simple, the operation is convenient and fast, but the device has the following defects in the clinical use process;
firstly, when the intervertebral space operation is carried out, cleaning water needs to be injected into the wound, but when the intervertebral space operation is carried out again, the device is influenced by the cleaning water, a clear visual field cannot be ensured for medical personnel, and the position needs to be repeatedly confirmed when the intervertebral space operation is carried out again;
secondly, when the intervertebral space operation is carried out, due to different clinical experiences of medical staff, the phenomenon that the instruments are inserted too deeply often occurs, the vertebra is damaged due to too deep insertion, the intervertebral space operation maintaining time is too short due to too shallow insertion, after a period of time, a patient suffers pain, the intervertebral space operation is needed again, and the operation is carried out at the same wound again, so that the operation difficulty of hospital staff and the healing degree of the patient are certainly improved;
thirdly, when the interbody fusion cage is implanted, the wound opening of the patient is fixed, so that the interbody fusion cage can only enter along the wound, but the device cannot smoothly guide the implantation of the interbody fusion cage according to the position of the intervertebral space, and the normal operation of the operation is influenced;
fourthly, as fascia, muscles and nerve roots at the spine are numerous, when the device is used for operation, the fascia, the muscles and the nerve roots are often damaged, so that secondary trauma to a patient is caused, and the success rate of the operation is greatly reduced;
fifthly, the device cannot play a role in assisting the introduction of the interbody fusion cage in the process of implanting the interbody fusion cage, so that medical personnel spend time when the interbody fusion cage is introduced, and the working efficiency is reduced;
sixth, in the intervertebral space operation, it is necessary to open a wound first and implant the cannula, but the cannula is likely to come into contact with the tissue between the wounds during the implantation of the wounds, thereby blocking the entry of the cannula.
In summary, the device, while enabling the performance of an assisted minimally invasive surgery, the skilled person is still studying in the art of how to achieve the implantation of the intervertebral cage in the intervertebral space, ignoring the various obstacles encountered when implanting the intervertebral cage; for example, how to guide and position the cage, how to protect the tissues around the spine, etc., in order to overcome such problems, technicians need to invest a great deal of effort to analyze the tissues around the spine of the human body and how to avoid the tissues during surgery, and the problem undoubtedly provides a new technical research height for the technicians; if the technical problem cannot be overcome, the intervertebral space surgery cannot be successfully completed, which is a technical bottleneck for medical personnel, and is a nightmare and attack on patients.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
