Description

Compression fracture restoration device for vertebral plastic surgery

The present invention relates to a compression fracture restoration device for vertebroplasty, and more particularly, to smoothly enter a fracture site of the vertebral body, to inflate a fracture site of the vertebral body very conveniently and precisely, and to inject bone cement It relates to a compression fracture restoration device for vertebroplasty that prevents the problem of collapsing of the restored vertebral body during the operation and has a very strong restoration state of the compression fracture portion.

In general, percutaneous vertebroplasty is a method that can be considered in patients with compression fractures of the vertebral body when conservative treatment methods such as drugs or physical therapy are not effective for a considerable period of time. It is a method of giving the patient stability of the spine.

A brief description of the procedure of such percutaneous vertebral body plastic surgery is as follows.

Before the procedure, magnetic resonance imaging (MRI) or computed tomography (CT) of the compression fracture site is performed to determine whether the procedure can be effectively and safely performed and to plan the procedure.

During the procedure, the patient is placed on the operating table and analgesic is administered in advance.

A substance called polymethylmethacrylate is injected after a needle is inserted into the vertebral body while watching a machine that can observe X-rays on a TV screen. Bone cement is a white substance that is liquid and hardens with heat.

This vertebral body plastic surgery is a relatively simple procedure, and it can restore the collapsed vertebral body to some extent or improve the curve of the back. It is a treatment that has been gaining popularity in recent years.

In the conventional vertebral body plastic surgery, there is a method of inserting a tubular bone cement injection tube into the compression fractured vertebrae and filling the bone cement, and in this way, the fractured vertebrae are restored.

In addition, there is also a compression fracture restoration method using a balloon catheter (balloon catheter). This conventional compression fracture restoration method inserts the silicone balloon portion of the balloon catheter into the fracture site, and spreads the collapsed fracture site by applying pressure to the inside of the silicone balloon to inflate it.

Bone cement is injected after opening the fracture site. Before injecting the bone cement, the silicone balloon must first be separated from the fracture site. In order to separate the silicone balloon from the fracture site, the pressure of the silicone balloon is removed and the volume is reduced and then pulled out.

The compression fracture restoration apparatus for vertebroplasty according to the present invention includes a compression fracture restoration means 10 , an open means 20 , a first handle 30 , and a second handle 40 .

The compression fracture restoration means 10 is inserted into the compression fractured vertebral body 1 to spread the collapsed vertebral body 1 and restore it.

The compression fracture restoration means 10 includes a head unit 11 inserted into the compression fractured portion, and a restoration unit 14 integrally connected to the head unit 11 and provided to spread outward.

The head 11 of the compression fracture restoration means 10 is formed in a conical shape having a sharpened portion 12, around which the head 11 is a compression fractured portion when the head 11 is rotated. An entry guide groove 13 is formed so as to be inserted while entering.

The restoration unit 14 of the compression fracture restoration means 10 has a pair of divergence wings 15, one end of which is integrally formed with the head unit 11, and a female screw unit 16 formed on the inner circumferential surface, and a pair of divergence wings ( 15) and is formed between the coupling space 17 to which the corresponding end of the second handle 40 is coupled.

When the opening means 20 enters along the female screw part 16 of the restoration part 14 around the connection part of the head part 11 and the restoration part 14 of the compression fracture restoration means 10, the opening wing A bending groove 18 is formed to guide the 15 to be bent outward.

In addition, in the portion of the bending groove 18 connected to the coupling space 17 , a deformation inducing hole 19 is formed to induce the flapping wing 15 to open outward.

A female screw part 16 is formed inside a pair of spreading blades 15. As shown in FIG. The female threaded part 16 is formed to be inclined downward from the end of the flapping wing 15 toward the inside, and the inclination angle θ of the female threaded part 16 is viewed from the centerline of the longitudinal section of the compression fracture restoration means 10 as a reference. 0.8~1.2°.

If the inclination angle (θ) of the female threaded part 16 is less than 0.8° with respect to the longitudinal section center line, the spreading means 20 must be rotated several times to sufficiently move the flapping wing 15 to unfold, and If the wheel is not rotated, the flapping wing 15 is not fully unfolded.

If the inclination angle (θ) of the female threaded part 16 exceeds 1.2° with respect to the longitudinal section center line, even if the spreading means 20 is rotated even a little, the spreading blade 15 is excessively spread, difficult to unfold Therefore, the inclination angle θ of the female screw part 16 is preferably 0.8 to 1.2° when viewed from the center line of the longitudinal cross-section of the compression fracture restoration means 10 .

The opening means 20 is embedded in the compression fracture restoration means 10, and when the compression fracture restoration means 10 is inserted into the fractured vertebral body 1, the compression fracture restoration means is moved along the inside of the compression fracture restoration means 10. (10) is opened to restore the fractured vertebral body (1).

The spreading means 20 has a male threaded part 21 formed on its outer circumferential surface so as to be fastened to the female threaded part 16 of the spreading wing 15 end, and the end of the first handle 30 is coupled to one end thereof. A groove 22 is formed.

Therefore, when the first handle 30 to be described later is rotated, the opening means 20 enters the inside of the compression fracture restoration means 10 along the female screw part 16, and the pair of flapping wings 15 are spread outwardly. catalog is provided.

The first handle 30 rotates the opening means 20 so that one end is coupled to the opening means 20 and the opening means 20 moves along the compression fracture restoration means 10 .

This first handle 30, the first handle 31 and; a first handle shaft 32 having one end fixed to the first handle 31 and the other end coupled to the opening means 20; It is formed at the other end of the first handle shaft 32 and is coupled to the corresponding end of the opening means 20 to rotate the opening means 20 when the first handle 31 is rotated inside the compression fracture restoration means 10 It consists of a first coupling end 33 that allows the compression fracture restoration means 10 to spread outward while moving along.

The second handle 40 is a second handle that rotates the compression fracture restoration means 10 so that one end is coupled to the compression fracture restoration means 10 and the compression fracture restoration means 10 is inserted up to the fractured vertebral body 1 . (40).

The second handle 40 includes a second handle 41; One end is fixed to the second handle 41, the other end is coupled to the corresponding end of the compression fracture restoration means 10, a hollow space is formed along the longitudinal direction therein so that the first handle shaft 32 is inserted. a second handle shaft 42; Compression fracture restoration means ( 10) consists of a second coupling end 43 to be inserted into the fractured vertebral body (1) portion.

The second coupling end 43 is made of a pair, and an insertion space 44 is formed between the pair of second coupling ends 43 . The second coupling end 43 of the second handle 40 is inserted into the coupling space 17 of the restoration unit 14, and when the second coupling end 43 is inserted into the coupling space 17, the insertion space At (44), the flaps 15 of the restoration part 14 are located.

Therefore, when the second coupling end 43 of the second handle 40 is coupled to the end of the restoration unit 14 of the compression fracture restoration means 10 , the second coupling end 43 is the coupling space of the restoration unit 14 . Engaged with (17), the flapping wings 15 of the restoration unit 14 are engaged with each other while being engaged with the insertion space 44 between the second coupling ends 43 . Therefore, the rotational force of the second handle 40 is transmitted to the compression fracture restoration means 10 by the second coupling end 43 and the flapping wing 15 .

The compression fracture restoration apparatus for vertebroplasty of the present invention having such a configuration is used as follows.

As shown in FIG. 2 , the compression fracture restoration apparatus for vertebroplasty of the present invention includes a first handle 30 , a second handle 40 , a compression fracture restoration means 10 , and an ablation means 20 .

In the present invention, the first handle shaft 32 of the first handle 30 is inserted into the second handle shaft 42 of the second handle 40, and the lower portion of the first handle 31 is inserted into the second handle. It is seated on the upper part of (41).

And, after fastening the opening means 20 to the compression fracture restoration means 10, the end of the opening means 20 is opposed to the end of the compression fracture restoration means 10, and then the female screw part of the opening wing 15 ( 16) is fastened to the male screw portion 21 of the opening means (20).

In this state, the second coupling end 43 of the second handle 40 is inserted into the coupling space 17 of the compression fracture restoration means 10, and the first coupling end 33 of the first handle 30 is inserted. is inserted into the coupling groove 22 of the opening means 20 . In this way, as shown in FIG. 1 , when the compression fracture restoration means 10 , the open means 20 , the first handle 30 , and the second handle 40 are combined, the compression fracture restoration means 10 as shown in FIG. 7 . ), the first handle 31 of the first handle 30 and the second handle 41 of the second handle 40 are pushed together When rotated, the head 11 is smoothly introduced into the vertebral body 1 by the thread-shaped entry guide groove 13 .

When the head 11 of the compression fracture restoration means 10 enters the compression fractured vertebral body 1, the first handle 31 of the first handle 30 is slightly pulled to release the first handle 31. 2 to be separated from the handle (41). At this time, the first coupling end 33 is still coupled to the coupling groove 22 of the opening means 20 .

Therefore, when only the first handle 31 is rotated in a state in which the first handle 31 and the second handle 41 are separated, the compression fracture restoration means 10 is not rotated and only the opening means 20 is rotated. , Accordingly, in the state in which the male screw part 21 of the opening means 20 and the female thread part 16 of the restoration part 14 are engaged, the opening means 20 is moved to the inside of the restoration part 14, and the flapping wings (15) spread outward.

Here, the female screw part 16 of the flapping blade 15 is formed to be inclined downward toward the inside from the end of the flapping blade 15, and the inclination angle θ of the female screw part 16 is the compression fracture restoration means (10). It is 0.8~1.2° when viewed from the center line of the longitudinal section.

If the inclination angle (θ) of the female threaded part 16 is less than 0.8° with respect to the longitudinal section center line, the spreading means 20 must be rotated several times to sufficiently move the flapping wing 15 to unfold, and If the wheel is not rotated, the flapping wing 15 is not fully unfolded. If the inclination angle (θ) of the female threaded part 16 exceeds 1.2° with respect to the longitudinal section center line, even if the spreading means 20 is rotated even a little, the spreading blade 15 is excessively spread, difficult to unfold

In addition, when the inclination angle θ of the female screw portion 16 exceeds 1.2° with respect to the longitudinal section centerline, only a small portion of the male screw portion 21 of the spreading means 20 is the female screw portion 16 of the spreading blade 15 . Since it is fastened to the , the male threaded part 21 and the female threaded part 16 cannot be stably engaged. Therefore, the inclination angle θ of the female screw part 16 is preferably 0.8 to 1.2° when viewed from the center line of the longitudinal cross-section of the compression fracture restoration means 10 .

On the other hand, when the opening means 20 is moved to the inside of the restoration unit 14, the opening wing 15 of the restoration unit 14 is opened to the outside, the head portion 11 and the opening wing 15. A bending groove 18 is formed between them. Since this bending groove 18 is formed in the form of a concave notch around the joint of the head 11 and the flapping blade 15, when the flapping means 20 enters the restoration part 14, the flapping wing (15) is easily folded and unfolded along the bending groove (18).

In addition, in the portion of the bending groove 18 connected to the coupling space 17 , a deformation inducing hole 19 is formed to induce the flapping wing 15 to open outward.

The deformation inducing hole 19 guides the opening wing 15 to be smoothly folded along the bending groove 18 and unfolded when the opening means 20 is moved to the inside of the restoration part 14, the deformation inducing hole The portion of the bending groove 18 meeting with (19) is the most vulnerable portion among the joint portions of the head portion 11 and the flapping blade 15, and thus the flapping means 20 enters the inside of the restoration part 14, and the flapping wing When (15) is pressed in the outward direction, the first bending is made at the site where the deformation inducing hole 19 and the bending groove meet. Accordingly, the flapping wings 15 are naturally bent along the entire bending groove 18 and unfolded while being bent from both ends of the bending groove 18 when the opening means 20 enters.

As described above, the present invention has the following effects.

First, in the present invention, when the first handle 30 and the second handle 40 are rotated at the same time, the compression fracture restoration means 10 is rotated, and accordingly, the head part ( The sharp part 12 of 11) smoothly enters the compression fracture vertebral body (1) site.

Therefore, the compression fracture restoration means 10 is formed by the sharp part 12 of the head part 11 suitable for penetrating into a cramped space and the entry guide groove 13 for guiding the compression fracture restoration means 10 to enter the fracture site side. ) smoothly enters the compression fracture vertebral body (1) part.

Second, in the present invention, when the first handle 30 is rotated after the compression fracture restoration means 10 is inserted into the fracture site, the opening means 20 is restored by the compression fracture along the female screw portion 16 of the flapping wing 15 . It enters the inside of the means (10), and accordingly, the pair of flapping wings (15) are spread outwardly and the compression fractured vertebral body (1) portion is restored while inflating.

Accordingly, when the first handle 30 is rotated little by little while the male threaded portion 21 of the spreading means 20 is screwed to the female threaded portion 16 of the spreading blade 15, the opening means 20 is moved along the screw thread. As it moves finely, the flapping wings 15 are spread apart. Therefore, when the first handle 30 is rotated, the fracture site is inflated, so the operation of inflating the fracture site is precise and simple.

Third, according to the present invention, by adjusting the first handle 30 and the second handle 40, the compression fracture restoration means 10 and the abduction means 20 are inserted up to the compression fracture site, and the compression fractured vertebral body 1 is inflated. Upon restoration, the first handle 30 and the second handle 40 are separated from the compression fracture restoration means 10 and the ablation means 20, and as such, the compression fracture restoration means 10 is the fractured vertebral body 1 part. By injecting the bone cement while supporting the bone, the compression fracture restoration means 10 and the ablation means 20 are fixed to the fractured vertebral body 1 together with the bone cement.

Therefore, the bone cement is injected while the compression fracture restoration means 10 and the ablation means 20 support the fractured vertebral body 1 , and the compression fracture restoration means 10 and the ablation means 20 use the bone cement. Since it is fixed to the vertebral body 1 together with the bone cement, the problem of the restored vertebral body 1 falling down during injection of bone cement is prevented, and the restoration state of the compression fracture portion is very strong.

On the other hand, a coating layer may be formed on the first coupling end 33 of the first handle 30 in order to improve the wear resistance and stain resistance of the metal surface.

The coating material of this coating layer is 20% by weight of dicyclopentadiene dioxide, 17% by weight of monoethanolamine, 13% by weight of hafnium, 15% by weight of organic magnesium oxide, 8% by weight of titanium oxide (TiO ₂ ), 8% by weight of aluminum oxide (Al ₂ O) ₃ ) It is composed of 9% by weight and 18% by weight of non-fluorochemical active, and the coating thickness can be formed to 8㎛.

Dicyclopentadiene dioxide and monoethanolamine serve to prevent corrosion, stain resistance, and discoloration, and hafnium is a transition metal element with abrasion resistance and corrosion resistance, and serves to have excellent waterproofness and corrosion resistance.

The organic magnesium oxide serves to impart alkali resistance and slidability to the surface of the coating film, the non-fluorochemical active serves as a surfactant, and titanium oxide and aluminum oxide are added for the purpose of fire resistance and chemical stability.

The reason why the ratio of the components and the coating thickness are numerically limited as described above is that the present inventors repeatedly failed several times and analyzed the test results through the test results, and the optimal abrasion resistance and stain resistance improvement effect at the above ratios was shown.

In addition, an antifouling coating layer made of an antifouling coating composition may be applied to the inside of the second handle shaft 42 of the second handle 40 to effectively prevent adhesion of and remove contaminants.

The antifouling coating composition contains 4A zeolite and ethyl cellusolve in a molar ratio of 1:0.01 to 1:2, and the total content of 4A zeolite and ethyl cellusolve is 1 to 10% by weight based on the total aqueous solution.

The molar ratio of the 4A zeolite and ethyl cellusolve is preferably 1:0.01 to 1:2. When the molar ratio is out of the above range, the applicability of the inside of the second handle shaft 42 is reduced or moisture adsorption on the surface after application is reduced. There is a problem in that the coating film is removed by increasing.

The 4A zeolite and ethyl cellusolve are preferably 1 to 10% by weight of the total aqueous solution of the composition, and when less than 1% by weight, there is a problem in that the applicability inside the second handle shaft 42 is reduced, and when it exceeds 10% by weight, Crystal precipitation is likely to occur due to an increase in the thickness of the coating film.

On the other hand, as a method of applying the present antifouling coating composition to the inside of the second handle shaft 42, it is preferable to apply the composition by a spray method. In addition, the final coating film thickness inside the second handle shaft 42 is preferably 800 to 2400 Å, more preferably 900 to 2000 Å. If the thickness of the coating film is less than 800 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2400 Å, there is a disadvantage that crystal precipitation on the coated surface is easy to occur.

In addition, the present antifouling coating composition can be prepared by adding 0.1 mol of 4A zeolite and 0.05 mol of ethylcellusolve to 1000 ml of distilled water and then stirring.

The reason why the ratio of the constituents and the thickness of the coating film were numerically limited as described above was that the present inventors repeated several failures and analyzed the test results.

In addition, the first handle 31 and the second handle 41 may be coated with an environmental fragrance material mixed with functional oil that helps to sterilize and relieve stress of workers.

The mixing ratio of the fragrance material and the functional oil is 95 to 97% by weight of the fragrance material and 3 to 5% by weight of the functional oil, and the functional oil is Osmanthus oil 50% by weight, Galangal oil 50% by weight.

Here, the functional oil is preferably mixed in an amount of 3 to 5% by weight based on the fragrance material. When the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant, and when the mixing ratio of the functional oil exceeds 3 to 5% by weight, the effect is not greatly improved, while the economic efficiency is lowered. Osmanthus oil psychologically purifies the mind and has effects on headaches and depression, and galangal oil has good effects on sterilization, insect repellency, and stress relief. Therefore, as the fragrance material mixed with these functional oils is coated on the first handle 31 and the second handle 41, the first handle 31 and the second handle 41 are sterilized and the stress of the operator, etc. It is possible to obtain effects such as reducing

The reason for limiting the components and the numerical value of the mixing ratio for the environmental fragrance material and functional oil is that the inventors failed several times and analyzed through the test results, and as a result, the optimal showed the effect of
