The present invention makes it possible to more easily exfoliate tissues 50 such as blood vessels, nerves, vas deferens, fallopian tubes, etc. at the time of ultrasound-assisted imaging or endoscopy, and at the same time, the tissues can be detached from surrounding tissues without damaging the tissues. It relates to a tissue peeling device capable of ion), the configuration is as shown in Figures 2 and 3, the hollow tube 100 is configured to be able to adjust the length greatly, and the flow of the rib 100 It comprises a connecting member 140 coupled to the front end. In more detail, the tube 100 is a guide diagram inserted to the periphery of the tissue 50 (hereinafter, the case where the tissue is 'vascular 50') to be peeled off after skin incision. The detachment device easily reaches the periphery of the blood vessel 50 to be detached by being inserted into the sheath 60, which is a tube, or directly inserted into the human body to protrude out of the sheath 60 from the inside of the human body. It's a guide to help you.

In this _{case, as} will be described later, when the tube 100 is formed in an arc shape, the tube 100 can be wrapped while separating the blood vessel 50 directly from the surrounding tissue, thereby peeling off without damaging the blood vessel 50 and the surrounding tissue. It can also play a role.

In addition, the rib 100 is made of a soft material having its own elasticity to facilitate access to the blood vessels 50 to be peeled off within the human body, is composed of multiple stages can be adjusted in length Desorption _: ᅵ The device can be moved forward and backward more easily, and it can be easily reached without damaging the surrounding tissue even when the chocks or blood vessels 50 to be peeled are located deep inside the human body. . On the other hand, the tube 100, as shown in Figure 8, may be configured in an arc shape, in this case, if the tube 100 is formed in an arc shape, the sheath 60 around the vessel 50 to be peeled off It protrudes outward and is configured to surround the blood vessel 50 to be peeled off while the length of the rib 100 changes.

Next, as described above, the number of the tube 100 separated into multiple stages may vary depending on the purpose of use, for example, when used for peripheral nerve anesthesia, the number of tubes 100 is one or two When used for peeling of the tissue, it may be composed of three or more tubes (100).

In addition, according to the elasticity of the material constituting the tube 100, the number of the tube 100 may be adjusted to three to seven, etc. Hereinafter, on the basis of the case made of three pieces of the rib 100 Embodiments of the tissue detachment apparatus according to the present invention will be described.

That is, the tube 100, as shown in Figures 2 and 8, the outermost first tube 110, the second tube 120 and the second flow tube 120 is inserted into the inner shaft is installed It comprises a third tube 130 is inserted into the installation of, the first tube 110, the second tube 120 and the third tube 130 are all made of a hollow shape, linear Consists of a tube having a straight or arc shape to enable reciprocating movement.

In more detail, when the tube 100 has an arc shape, the first tube 110, the second tube 120 and the third tube 130 is a cylindrical tube having an arc shape having a circumferential angle of about 150 degrees Consisting out of the sheath 60 when the first tube 110 to the second tube 120 and the third tube 130 is sequentially projected to the periphery of the blood vessel to be peeled off when the protrusion is completed It is configured to wrap. At this time, it is a matter of course that the deployment order of the first to third flow grooves (110, 120, 130) can be reversed.

That is, the angle forming the circular arc of each tube 100 is divided by 360 degrees to form a circle divided by the number of tubes, so that each of the ribs 100 can support each other In order to secure a portion, it should be a value added to a certain angle, as in the embodiment of the present invention, when the peeling device is composed of a total of three ribs (110, 120, 130) overlap each other at 120 degrees divided by 360 degrees 3 By adding about 30 degrees to the supporting portion, each of the ribs 110, 120, 130 is formed to have a circumferential angle of about 150 degrees.

At this time, in the development process of the tube 100 as described above, the peeling between the blood vessel 50 and the surrounding tissue is naturally formed, and the peripheral circle of the blood vessel 50 to be peeled off by the shape of the arc 100 made of an arc shape. Because it approaches in a curved direction so that it can be wrapped, the blood vessel 50 and surrounding tissues are not damaged during the exfoliation process.

In addition, since the tube 100 including the first tube 110, the second tube 120, and the third tube 130 has its own elasticity, the tube 100 can be easily inserted into the sheath 60. .

At this time, although not shown, guide grooves (not shown) are formed on inner surfaces of the first and second tubes 110 and 120, and second and third inserts are inserted into the first and second tubes 110 and 120. The outer surface of the tube (120, 130) is formed so that the guide protrusion which is fitted into the guide groove is formed so that rotation does not occur during the deployment and recovery of the first to crab trifluid (110, 120, 130) Of course you can.

Next, the connecting member 140 is to be provided at the front end of the tube 100, the separation tool such as fluid spray pipe 200, the ligation chamber 150 to be described later to be connected and supported It is to play a role.

At this time, the connecting member 140, as shown in Figure 3, the front end portion of the tube 100, preferably the n-th tube located in the innermost of the tube 100 is composed of a plurality of (in this embodiment It is formed integrally with the front end portion of the three tubes (130) or detachably coupled.

In addition, the front end portion of the connecting member 140 is configured to minimize the damage to the blood vessel 50 or the surrounding tissue during the exfoliation process using the tube 100 by forming a curved surface like the hemispherical shape. The diameter (outer diameter) is larger than the diameter (inner diameter) of the first rib 110 so that when the tube 100 is recovered, the second tube 120 and the first tube 110 can be simultaneously recovered. It is. That is, since the diameter of the third tube 130 is smaller than the diameter of the second tube 120 or the first flow tube 110, when the tube 100 is recovered after peeling, only the third tube 130 is recovered and the first tube 130 is recovered. There may be a problem that the two tubes 120 and the one tube 110 is not recovered, the diameter of the connecting member 140 coupled to the front end of the third tube 130 as described above the first tube 110 When the diameter of the tube 100 is greater than 100, the connecting member 140 can pull the second tube 120 and the first tube 110 together when the tube 100 is dilution. You can freely perform the development or recovery of.

Next, the tissue peeling apparatus according to the present invention, as shown in Figure 4, to be configured to further comprise a fluid injection pipe 200 as a peeling tool is installed connected to the connecting member 140. In addition, the fluid injection pipe 200 serves to facilitate separation by spreading the gap between the tissues by the pressure of the fluid to be injected by injecting a fluid, such as air or water.

That is, the biggest problem in the case of peeling tissue is that the tissue to be peeled and the surrounding tissue are so close that the surrounding tissue is damaged during the peeling. For example, if the tissue to be peeled is the blood vessel 50, the blood vessel 50 The connective tissue around the skin is characterized by a relatively smaller mechanical strength than the blood vessel 50.

Injecting a fluid between the blood vessel 50 and the connective tissue using this feature increases the pressure in the space into which the fluid is injected and causes the fluid to spread to the surroundings, and the fluid is spread to the relatively weak connective tissue. the combined surrounding the blood vessel 50, the organization ^is' separated with a fluid between it is possible to easily and safely than the separation vessel (50).

In this case, a through hole 148 through which the fluid injection pipe 200 passes is formed at the center of the front end of the connection member 140, and at least one injection hole 210 is formed at the front end of the fluid injection pipe 200. It is formed so that the fluid supplied from the fluid supply means (not shown) is connected to the rear end of the fluid injection pipe 200 is configured to inject between the blood vessel 50 and the connective tissue, the fluid supply means is injected The pressure of the fluid may be adjusted to increase the space between the blood vessel 50 and the connective tissue by the pressure of the fluid. On the other hand, as shown in Figure 5, by coupling the needle (needle) (220) to the front end of the fluid injection pipe 200 may be injected to the fluid, when using the needle 220 as described above, When the fluid is used as a local anesthetic, the present invention can also be used for nerve block surgery such as regional nerve block.

In other words, when performing nerve block surgery under ultrasound guidance, or when performing various nerve block surgery in the pain clinic, local anesthetics should be injected to the periphery of the nerve, the connection provided at the front end of the tube 100 formed in multiple stages as described above Absence 140 or. When the needle is coupled to the front end of the fluid injection pipe 200, there is an advantage that the local anesthetic can be injected to the rear side of the nerve without directly damaging tissues such as blood vessels or nerves.

In addition, as a result of the present research, it is known that spraying a small amount of local anesthetics around the nerves has a higher rate of nerve block than to spraying only one area, so that a needle for drug injection into the tissue detachment device according to the present invention is used. When used in combination, it is possible to obtain a high neuroblocking rate while using a smaller dose of local anesthetic.

At this time, although not shown, the front end of the fluid injection pipe 200 or the connection member 140 to have a needle (needle) form to form the needle and the fluid injection pipe 200 or the connection member 140 integrally. It is also possible, of course, may be used in conjunction with the needle directly to the front end of the rib (100). In addition, as shown in Figure 6, the expansion member 230 may be installed outside the front end of the fluid injection pipe 200, the plurality of injection holes 210 is formed, the expansion member 230 is a blood vessel (50) It is a function that makes it possible to safely expand the space between the network and the surrounding organization.

That is, by engaging the expansion member 230 to expand by the fluid discharged from the injection hole 210 (mainly air is used) to the front end of the fluid injection pipe 200, damage to the surrounding tissue in the peeling process The vessel 50 can be peeled safely without being added.

In more detail, as shown in FIG. 7A, when the space between the blood vessel 50 and the surrounding tissue to be peeled is narrow, it is difficult to insert the peeling tool, that is, the connecting member 140 and the tube 100. In Figure 7 (b) As shown, the fluid is injected through the fluid supply means installed at the rear end of the fluid injection pipe 200 while the fluid injection pipe 200 having a relatively small diameter is inserted into the space between the blood vessel 50 and the surrounding tissue. If supplied, in FIG.

As shown in (c), as the expansion member 230 coupled to the outside of the front end of the fluid injection pipe 200 expands, the space between the blood vessel 50 and the surrounding tissue can be expanded.

Thus, if the space between the blood vessel 50 and the surrounding tissue is expanded, Figure 7

As shown in (d), the expansion member 230 is contracted again so that the connecting member 140 can be moved forward. For this purpose, the fluid supply means enables forward and reverse control so that the supply of fluid as well as recovery is possible. It is configured to be possible. The configuration of the fluid supply means for alternately generating the supply and recovery of the fluid by alternately controlling the stationary power is a technology that has been used in various fields, and is not intended to claim the present invention. Detailed description will be omitted.

Next, when the expansion member 230 is contracted, even pushing the tube 100

As shown in 7 ( _e ), the connecting member 140 provided at the front end of the tube 100 enters the widened space between the blood vessel 50 and the surrounding tissue through the outside of the expansion member 230. In this state, as shown in (f) and (g) of FIG. 7, the fluid injection pipe 200 is pushed back into the narrow space between the blood vessel 50 and the surrounding tissue, thereby expanding the expansion member 230. By repeating the above-described process, such as dilation, as shown in FIG. 7H, the space between the blood vessel 50 and the surrounding tissue can be expanded, thereby allowing the vessel 50 to be detached more easily and safely. will be.

In addition, the tissue to be peeled off may be peeled from the surrounding tissues only by the above-described process, and as shown in FIG. 10, the tube 100 may be directly coupled to the front end of the tube 100 by expanding the expansion member 230. Of course, the expansion member 230 may be configured to expand and contract by the fluid supplied and recovered.

On the other hand, the tube 100 may be connected to the peeling pressure measuring device 180 to measure the pressure applied to the tube 100 during the peeling process of the blood vessel 50, the peeling pressure measuring device ( 180 into the tube 100 human body When the blood vessel 50 is separated from the surrounding tissue by entering, the pressure applied to the tube 100 is measured so that the operator can know, thereby preventing the tissue from being peeled off with excessive force. It will serve to prevent damage to the product.

In more detail, the peeling pressure measuring device 180 includes a housing 182, a coupling part 184, and a spring 186, as shown in FIG. 9, wherein the housing 182 is disposed at an inner side thereof. A space portion 185 into which the coupling portion 184 and the spring 186 are inserted is formed to serve to fix and support the coupling portion 184 and the spring 186 to obtain more accurate peeling pressure measurement results. The coupling portion 184 is coupled to the rear end of the tube 100 to serve to transfer the pressure applied to the tube 100 in the peeling process, the spring 186 of the coupling portion 184 It is fitted to the rear outer circumferential surface and shrinks by the pressure generated during the peeling process, and serves to measure the peeling pressure by the degree of shrinkage.

At this time, after forming the stepped portion 185a in the space portion 185 formed inside the housing 182 to allow the spring 186 to be supported, the housing daewoo at the position where the spring 186 is inserted ( By forming a scale 187 to measure the contraction degree of the spring 186 on one side of the 182, it is possible to mechanically measure the peeling pressure without a separate sensor. Here, the housing 182 is made of a transparent material to visually check the degree of shrinkage of the spring 186.

In addition, although not shown, a pressure sensor such as a load cell in the form of a film may be used as the peeling pressure measuring device 180. The peeling process may be performed by installing the load sal inside the tube 100 or the fluid injection pipe 200. In addition, the pressure applied to the tube 100 or the fluid injection pipe 200 may be configured to be confirmed through an electrical signal generated from the load sal.

Therefore, according to the tissue detachment apparatus according to the present invention as described above, it is possible to safely and easily detach the tissue 50, such as blood vessels during surgery through an ultrasound image or endoscope, and at the same time the pressure of the fluid Alternatively, the tissue and surroundings to be peeled off may be expanded to expand the space between the tissue to be peeled off and the surrounding tissue by using an expansion member that is expanded by hydraulic pressure.

That is, the angle forming the arc of each tube 100 is divided by 360 degrees constituting the circle by the number of tubes, and then the predetermined angle is added to secure the overlapping portions so that each tube 100 can support each other. As in the embodiment of the present invention, when the peeling device is composed of three tubes (110, 120, 130) in total, about 30 degrees are supported by overlapping each other at 120 degrees divided by 360 degrees. In addition, each tube 110, 120, 130 is formed to have a circumferential angle of about 150 degrees.

At this time, in the process of developing the tube 100 as described above, the separation between the blood vessel 50 and the surrounding tissue is naturally performed, and the periphery of the blood vessel 50 to be peeled off by the shape of the tube 100 having an arc shape. Approach in a curved direction so that it can be wrapped in a circular shape will not cause damage to the blood vessel 50 and the surrounding tissue during the exfoliation process.

In addition, since the rib 100 including the first tube 110, the second tube 120, and the third tube 130 has its own elasticity, it may be easily inserted into the sheath 60.

At this time, although not shown, guide grooves (not shown) are formed on inner surfaces of the first and second tubes 110 and 120, and are inserted into the first and second tubes 110 and 120. Guide protrusions fitted into the guide grooves are formed to protrude on the outer surfaces of the second and third tubes 120 and 130 so that rotation is not generated during the deployment and withdrawal of the first to third tubes 110 and 120 and 130. Of course, it can also be configured. Next, the connecting member 140 is to be provided at the front end of the tube 100, the tool such as the ligation chamber 150 to be described later to be connected to the tool installed so that the ligation chamber 150 is peeled off It is to position in space.
