DISKTHERAPYIMPLANT,AND OPERATIONMETHOD OFIMPLANT
[Technical Field] The present invention relates to a disk therapy implant and an operation method of the implant, and more particularly, to a disk therapy implant having a simple structure and capable of preventing recurrence of a ruptured disk, and a disk therapy implant operation method which the disk therapy implant can be simply operated by a surgeon.
[Background Art]
Generally, a disk indicates gristle that is disposed between vertebrae of a human body, supports the weight of the human body, absorbs shocks, and performs a cushioning function. As a human gets older or is injured, the disk may become damaged, the disk between the vertebrae is forced out therefrom and presses nerves around the disk so that he/she experiences discomfort.
In the event of a considerable damage to the disk, there is need for surgery. Disk surgery is divided into two methods, that is, a method for simply removing a part of the disk, and a method for removing the disk and fixing the vertebrae with an implant.
Both of the surgery methods can expect some therapy effect, however, if the disk is simply removed, there may be a functional absence in the corresponding so that it may cause a discomfort after the surgery and the disk disease may be recurrent, and the implant fixing method needs a large surgery space and a lot of time for the surgery and the corresponding operated disk joint may lose the motor function, so that the disk joints around the operated disk may be suffered with rapid regression.

Hereinafter, the structure of the present invention will be described in detail with reference to the accompanying drawings as follows. A disk therapy implant according to the present invention, as shown in
Figs. 1, 3, and 4, includes a balloon 10 inserted into a disk between a vertebrae 1 and a vertebrae 2 and provided with an injection hole 11, nucleus filler 50 for filling the balloon 10, and a lead valve 20, installed in the injection hole 11, for control the injection and extraction of the nucleus filler 50.
The balloon 10 is preferably made of material that is harmless to humans and is expandable between the vertebrae 1 and the vertebrae 2, such as silicon, latex, or the like.
The balloon 10, as shown in Fig. 1, is formed with an accommodating space to be filled up with the nucleus filler 50, and the injection hole 11 through the nucleus filler 50 is injected. The corresponding patient's tissue to be operated is cut in size of approximately 5 mm to 10 mm, a trocar 40 is fixed to the cut portion, and then the balloon 10 is inserted between the vertebrae 1 and the vertebrae 2 through a trocar 40. Preferably, growth factor used as a harmless and suitable material, collagen, synthetic polymer, liquid silicon, solid silicon, synthetic oil, saline, hydrogel, latex, or the like are used as the nucleus filler 50.
The nucleus filler 50 is supplied into the accommodating space 12 through an injection tube of which an end is connected to the injection hole 11 and the other end is exposed to the exterior. The nucleus filler 50 is supplied through the injection tube 20 in the state of the gel state so as to fill the balloon 10.
The lead vale 20, as shown in Figs. 3 and 4, is installed at the injection hole 11 of the balloon 10 connected to an injection tube 30, makes the nucleus filler 50 flow in one way direction so as to filling the balloon 10 and to prevent the nucleus filler 50 from being leaked to the exterior. Therefore, the lead vale 20 controls the injection and extraction of the nucleus filler 50, so that the operator (a surgeon) can fill the balloon 10 with the nucleus filler 50 by adjusting the amount of the nucleus filler 50 according to the patient's condition. Meanwhile, in another embodiment of the disk therapy implant according to the present invention, as shown in Fig. 5, since the nucleus filler 50 consists of a plurality of balls 60, the surgeon can more easily perform the surgical operation with the disk therapy implant according to the present invention to the patient. In still another embodiment of the disk therapy implant according to the present invention, as shown in Fig. 6, wires 70 as the nucleus filler 50 are accommodated in the balloon 10, so that the surgeon can perform the surgical operation in a simpler manner.
As described above, the surgical operation using the disk therapy implant according to the present invention will be described in detail as follows.
The surgical operation using the disk therapy implant according to the present invention, as shown in Figs. 1, 3, and 4, includes the steps of cutting a portion of a patient's tissue to be operated, of fixing the surgery portion by inserting a trocar 40 into the cutting portion, of inserting a balloon 10 provided with an injection tube 30 through the trocar 40, and of filling the balloon 10 with nucleus filler 50 through the injection tube 30.
Here, in the step 2), it is noted that according to the patient's diseased part, the insertion position of the balloon 10 to be inserted between the vertebrae 1 and the vertebrae 2 is detected so as to cut the tissue corresponding to the patient's diseased part, while the tissue is cut by a length of approximate 5 mm to 10 mm into which the balloon 10 can be inserted. The trocar 40 is connected to the patient disk at an end thereof, and the other end thereof is exposed out of the patient's body. The trocar 40 is inserted into the cutting portion so that the balloon 10 can be inserted into the disk between the vertebrae 1 and the vertebrae 2, and the balloon 10 can be easily inserted through the trocar 40.
The injection tube 30 exposed to the exterior of the patient's body is detachably connected to the balloon 10 so that the balloon 10 is inserted between the vertebrae 1 and the vertebrae 2 in the shrunken state through the trocar 40 and by using other medical instruments, however, as shown in Fig. 2, after the insertion, the balloon 10 is expanded by filling the nucleus filler 50 therein so as to firmly support the vertebrae between the vertebrae 1 and 2.
The filling step is a step of filling the nucleus filler 50 in the balloon 20 from the exterior of the patient's body, in the filling step, the nucleus filler 50 is filled up the balloon 10 by using the injection tube 30 of which an end is connected to the injection hole 11 of the balloon 10 and the other end is exposed to the exterior.
According to the surgery method of the disk therapy implant in accordance with the present invention, the surgery portion of the patient's tissue is cut approximately by a length of 5 mm to 10 mm, the balloon 10 having the injection tube 30 is inserted into the surgery portion in the state of inserting the trocar 40 into the cutting portion, and then the nucleus filler 50 is supplied into the balloon 10 through the injection tube 30 that is detachably connected to the injection tube 30.
[Industrial Applicability] As described above, the present invention has advantages of preventing reoccurrence of the disk disease by inserting the disk therapy implant with a simple structure between the vertebrae so as to complement the removed disk from the patient's body, of expecting the patient's rapid recovery by easily performing the surgery of the disk therapy implant and reducing the time for the surgery, and of safely cutting the diseased part of the patient's tissue so as to prevent the diseased part of the patient's body and the peripheral nerves from being damaged due to the mistake by the surgeon or the medical instruments.
