Definitions
- the present invention relates to a bi-directional spinal endoscopic surgery method and a diamond shaver used therein, and more particularly, to a bidirectional spinal- And a diamond shaver that can be effectively applied to the bidirectional vertebral endoscopic surgery method.
- the intervertebral disc absorbs and disperses the body's load and impact between the vertebrae, as well as holding the neighboring vertebrae so that they do not slip away.
- the vertebrae also separate the vertebral bones adjacent to the vertebrae To keep it smooth.
- the intervertebral foramen is narrowed by various causes such as progress of aging, excessive exercise, bad attitude by habituation, and the like. More specifically, it becomes narrower due to fibroblasts adhered to tissues such as joint hypertrophy or disc degeneration around the vertebral segment, inflammatory substances liberated from damaged discs or cartilage tissues, nerve branches inside the intervertebral space, and surrounding ligaments.
- the nerve roots coming out of the spinal cord through the intervertebral disc are compressed. These pressures can cause pain in the neck, shoulders, back and arms, weakness of the muscles, as well as gait disorders throughout the body, such as gait dysfunction and significantly reduced bowel and bladder control.
- the stenosis of the intervertebral foramen due to aging is caused mainly by the thickening of the posterior joint and the yellow ligament.
- the conventional incision is a method of largely cutting the surgical site, and thus has a disadvantage in that it has a high probability of damaging the blood vessels and important blood vessels, as well as important spinal nerves and muscles, Respectively.
- PSLD endoscopic lumbar lumbar decompression
- percutaneous endoscopic interdisternal decompression is a difficult operation in itself, and even though a microscope or spinal endoscope is used as an auxiliary device, it is often difficult to operate because of poor visual field.
- the nerve branches surrounded by fibrous adhesions can be treated to some degree by only epidural nerve treatment or epidural nerve dissection in the early stage of weak adhesion or mild degree of stenosis.
- Percutaneous intervertebral disc enlargement is the most effective treatment for this condition.
- Percutaneous intervertebral disc enlargement can be used to solve the pain by removing the cohesive part or the overturned bones that penetrate the patient's skin and directly insert the expanding device into the intervertebral foramen, It is a procedure that improves the blood flow around the nerve by releasing pressure applied to the nerve.
- the surgical instrument introduced in the preceding document is a trocar which is inserted into a target point through the skin for widening an intervertebral space by removing adhesives or the like that block an intervertebral disc and a cannula which is guided by the trocar, And an end mill having a blade tip at its end passing through a guide hole of the cannula and a cullet having a tip for removing the end mill and being inserted into the guide hole and scraping the tissue inside the intervertebral disc.
- the conventional surgical instrument described above has a disadvantage in that it is not suitable for accurate operation because it has a simple structure and can not be expected to have other effects other than the action of scraping off a tissue that has been broken and the tissue of a target site.
- a blade tip can severely damage normal tissue or touch the blood vessels and cause internal bleeding.
- the use of the end mill itself is very inconvenient.
- the practitioner In order to use the end mill, that is, in order to rotate the blade tip, the practitioner must hold the handle of the end mill and rotate it to the left and right by applying a force as if turning the endoscope to the left and right.
- the rotation speed of the coagulated tissue is not fast, so that the coagulated tissue is not cut but often torn.
- the normal tissue may be torn apart during the tipping process of the adherent tissue.
- the present invention has been made in order to solve the above problem, and it is possible to secure a clear visual field so that it can accurately identify and remove the lesion, so that the safety is high and there is almost no scarring due to minimal incision and there is a risk of muscle damage, bleeding and infection And to provide a bi-directional vertebra operation method that enables a faster treatment effect to be obtained.
- a diamond drill bur with a diamond powder embedded therein is used as a means for shaving the object to be removed. Therefore, the diamond cutter has excellent ability to cut fine, high precision of operation, less burden of bleeding due to cutting, The purpose is to provide a shaver.
- the present invention provides a bi-directional vertebra operation method comprising: a passage securing step for securing an operation hole and an endoscope hole extending toward a surgical target site in a patient body and separated from each other; A surgical tool inserting step of inserting a surgical tool necessary for surgery through the surgical hole secured through the passage securing step; Inserting an endoscope apparatus through the endoscope hole; A surgical step of performing surgery using a surgical tool inserted into the surgical hole and monitoring a surgical site through an endoscope apparatus; A removal step of removing the surgical instrument and the endoscope apparatus after the completion of the operation step; And a suturing step of suturing the opening of the endoscope and the surgical hole after completion of the removing step.
- the passage securing step may include: A marking step of marking an opening position of an operation hole and an endoscope hole on a skin of a patient, a cutting step of cutting the display part displayed through the marking step, and a step of inserting an extension tube into the body through the cut- A tubular inserting process for forming a passage toward the region to be operated, and a passage expanding process for expanding the diameter of the passage using an enlarged tube for each size.
- the saline solution supply step may include supplying a saline solution supplied from the outside to the surgical site to discharge an object to be discharged from the surgical site to the outside of the body.
- the surgical hole and the endoscope hole are spaced apart from each other, and the proximal end of the endoscope is adjacent to the surgical site while extending into the body.
- the angle between the surgical hole and the endoscope hole is 90 degrees or less.
- the diamond shaver according to the present invention is inserted into an operation hole of an operation hole and an endoscope hole extending toward a part to be operated by a patient to shave and remove an object to be removed, which is located at a part to be operated,
- An outer tube having an inclined open portion inclined so as to have an angle between the outer tube and the outer tube;
- a tube holder fixed to a rear end of the outer tube;
- a handpiece attacher installed at the rear of the tube holder;
- a head portion having a cutting tip fixed to a front end portion of the electric shaft portion and having a cutting diamond powder embedded in the surface thereof, the drill bar having a shaft portion rotatably installed in the outer tube,
- a diamond drill having a body;
- a controller connected to the handpiece and outputting a control signal;
- a foot switch connected to the controller and operated by a user to step on the foot.
- the cutting tip is disposed so as to be partially exposed to the outside of the outer tube through the inclined opening so as to be in contact with the object to be cut.
- the electric shafts include: A hollow shaft extending in the longitudinal direction; and a tip portion positioned at a distal end of the hollow shaft and providing a coupling hole for engaging with the head portion; A coupling part detachably coupled to the coupling part, and a cutting tip supporting part integrally formed with the coupling part and supporting the cutting chip.
- the cutting tip supporter includes: A tapered body for receiving rotational force from the adapter, and a resilient supporting member for connecting the tapered body and the cutting tip and being elastically deformable.
- the elastic support member may include: And includes a cylindrical torsion rubber or coil spring having a constant diameter.
- a fluid guiding part for passing saline solution is provided between the tube holder and the handpiece adapter.
- the bidirectional spinal endoscopic surgery method of the present invention can secure a clear field of view and accurately identify and remove lesions of the body. Therefore, it is safe, and there is little scarring due to minimal incision, and there is no risk of muscle damage, bleeding or infection A rapid therapeutic effect can be obtained.
- the diamond shaver of the present invention has a diamond drill bur with a diamond powder embedded therein as a means for shaving the object to be removed at the time of bidirectional spinal cord endoscopic surgery. Therefore, the diamond shaver has excellent fine cutting ability and high precision of surgery, So that the operation time can be shortened.

- the bi-directional vertebral endoscopic operation method includes a passage securing step 100, a surgical instrument inserting step 110, an endoscope inserting step 120, a surgical step 130, a removing step 140, , And a sealing step (150).
- the passage securing step 100 is a process of forming two passages extending toward a part to be operated, that is, an operation hole B and an endoscope hole A in the patient, 102, a tubular inserting process 103, and a channel expanding process 104.
- the marking step 101 is a step of marking a point where a surgical hole (B) and an endoscopic hole (A) are to be formed on a vertebra of a patient lying down.
- a surgical hole (B) and an endoscopic hole (A) are to be formed on a vertebra of a patient lying down.
- an inlet for inserting a tool set such as the tool kit 20 or the diamond shaver 30 is displayed.
- the two points to be marked must be spaced apart. The point to be marked depends on the location of the surgical site. Of course, the more distant the lesion is, the farther the distance between the two points is.
- the surgical hole (B) and the endoscope hole (A) are independent passages, and the entrance portion is spaced apart, but it meets at the body lesion site and takes the shape of two sides of the triangle.
- the incision process 103 is a process of opening the entrance for inserting the extension tube 21 by cutting the marking site using, for example, a surgical scalpel.
- the incision length may be around 5 mm.
- the subsequent tubular inserting process 103 is a process of forming a straight passage toward the site to be treated by inserting the enlarged tubular body 21 into the body by using the incised portion opened by the incision process 102 as an inlet.
- the first expansion tube body 21 used first is the first expansion tube body 21a having the smallest diameter.
- the passageway expansion process 104 is a process of expanding the diameter of the passageway by using an enlarged pipe body for each size. For example, in a state in which the first extension tube 21a is fitted, the first extension tube 21a is inserted by inserting the second extension tube 21b, and after inserting the third extension tube 21c, 21b.
- Such a channel expanding step 104 can be applied to both the endoscope hole A and the surgical hole B.
- the diameter of the surgical hole B into which the surgical tool set goes in and out needs to be relatively large.
- the endoscopic hole (A) and the surgical hole (B) formed through the passage securing step (100) are spaced apart from the epidermis of the patient, but they meet at the in-vivo surgical site.
- the subsequent insertion of the surgical instrument 110 is a process of inserting a surgical tool necessary for the operation through the surgical hole B secured through the passage securing step 100. That is, it is a process of inserting the necessary surgical instruments according to the progress of the operation.
- the high frequency probe 40, the K-punch 50, and the diamond shaver 60, as well as the tool kit 20, are optionally inserted through the operation hole B as required.
- the endoscope device inserting step 110 is a process of inserting the endoscope device 70 through the secured endoscope hole A.
- the operation step 130 is a process of operating the surgical tool set 100 inserted in the surgical hole B and monitoring the surgical site through the endoscope apparatus 70.
- the operation step 130 is a process of actually performing the treatment on the site to be treated in the body. As the treatment progresses, the necessary tools are inserted into the body through the surgical hole (B). It goes without saying that the operation status is continuously monitored through the endoscope apparatus 70 during the operation.
- the saline supply process is performed during the operation 130.
- the saline supply process is a process of supplying the saline solution supplied from the outside to the surgical site and discharging the discharged object generated during the operation to the outside of the body.
- the saline solution is guided through the guide tube 71a of the sheath mechanism.
- the injected saline excretes debris and tissue removed at the surgical site to the outside, and effectively discharges very fine powder removed by using the diamond shaver 60.
- the subsequent removal step (140) is a process of removing the used surgical tool and the endoscope device from the body.
- the surgical instrument should be removed first, and the endoscope apparatus 70 should be removed later.
- the endoscope camera 73 is used to check and confirm the surgical site, and then remove it.
- a sealing step 150 is performed to seal the openings of the operation hole B and the endoscope hole A, and the operation is completed.
