1 is a schematic perspective view of a medical trocar according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the medical trocar of FIG. 1, and FIG. 3 is a cross-sectional view of the medical trocar of FIG. 1.

Referring to Figures 1 to 3, the medical trocar 100 according to the present invention has a structure capable of adjusting the direction for easy operation, the body portion 110 and the bushing portion 120 and the direction control The unit 130 is included.

The main body 110 accommodates the bushing 120 to be described later, and guides the insertion path of the bushing 120, and includes a housing 111 and a valve member 113.

The housing 111 is a tubular structure in which a through hole 112 is formed along a longitudinal direction to accommodate the bushing part 120 to be described later. The housing 111 is flexible to change an end direction through a shape deformation. It is made of flexible material.

The valve member 113 is installed inside the housing 111 and is provided in a one-way valve structure for blocking fluid flow from an end in close contact with the body B to an opposite end. Therefore, according to the valve member 113 in the present embodiment, the fluid containing the blood and secretions generated from the body region punctured by the bushing part 120 flows backward through the through-hole 112 of the housing and discharges to the outside. Can be prevented.

The bushing portion 120 is a structure for drilling the end portion in close contact with the local region of the body (B), is accommodated in the through-hole 112 of the housing 111. The end portion of the bushing part 120 is formed of a sharp tip, and the tip 121 is made of a material having excellent rigidity so that the body B can be easily perforated.

The direction adjusting part 130 is a structure for adjusting the direction of the end side housing 111 in which the tip portion 121 is located, the wire member 131 and the rotation pulley 132 and the handle member 133 and elastic Member 134.

The wire member 131 is a structure for transmitting the external force generated when the operator manipulates the handle member 133 described later to the housing 111.

Both ends of the wire member 131 are installed to face each other at the end of the housing 111 adjacent to the body (B) during the procedure. In more detail, one end of the wire member 131 is installed on the inner wall of the end of the housing 111, is wired along the longitudinal direction of the housing 111, and wound around the rotation pulley 132, and then again of the housing 111. Wired along the longitudinal direction, the other end is provided on the inner wall opposite the housing 111.

At this time, in the present embodiment, the wire member 131 is alternately wired once to match the rotational direction of the handle member 133 which will be described later with the housing 111 direction, but is not limited thereto.

Thus, the wire member 131 is a pair is installed on the inner wall opposite the housing 111, respectively, are wired to face each other and leads to a state surrounding the rotation pulley 133. Through this structure, the wire members 131 facing each other in cooperation with the rotation of the rotation pulley 133 move in different directions, thereby deforming the shape of the end portion of the housing 111.

The pivoting pulley 132 is rotatably installed at the end of the opposite housing 111 on the side where the tip 121 is located during the procedure, and is coupled with the handle member 133 to be described later.

One end of the handle member 133 is coupled to the rotating shaft of the rotation pulley 132, the other end is exposed to the outside to be operated by the operator. Therefore, the rotational pulley 132 and the wire member 131 operate by the operator operating the handle member 133.

The elastic member 134 is to apply an elastic force to the handle member 133 and the rotation pulley 132 to be restored to its original position when the pressing force is released from the operator, in this embodiment the elastic member 134 is a rotation pulley It is provided in the form of a spring structure wound on 132.

Hereinafter, a description will be given of a treatment method using the medical trocar 100 according to an embodiment of the present invention.

4 schematically illustrates the principle of operation of the medical trocar of FIG. 1.

First, in a state in which the tip portion 121 of the bushing portion 120 is in close contact with a portion to be treated, the skin is perforated when a force is applied. After drilling, the tip 121 is removed from the housing 111 inserted into the human body B. At this time, the secretion containing blood from the inside of the body (B) may be introduced into the housing (111). However, in the present invention, by restricting the flow of secretion that the valve member 113 is introduced, it is possible to prevent the discharge of the discharge through the housing 111 to the outside.

On the other hand, as shown in Figure 4, in the state where the medical trocar 100 of the present embodiment is inserted into the body (B), when the operator applies the pressing force to the handle member 133, it rotates to the end of the handle member 133 Possible rotational pulley 132 is rotated.

The wire member 131 mounted on the rotation pulley 132 moves in conjunction with the rotation of the rotation pulley 132. At this time, the wire members 131 which are arranged side by side facing the housing 111 are moved in different directions while both ends thereof are coupled to the inner walls of the housing 111 different from each other, and the ends of the housing 111 are Deformation is caused by the force applied from the wire member 131.

In more detail, a pushing force is applied to one wall of the housing 111 by a wire member 131, and a pulling force is applied to the other wall of the housing 111, so that the housing 111 having flexible characteristics is provided. The end of the bend is changed in direction.

When the operator releases the pressing force from the handle member 133, the rotation pulley 132 receives an elastic force from the elastic member 134, and rotates in a direction opposite to the rotation direction when the pressing force is applied by the operator. As the rotation pulley 132 rotates in the opposite direction, the wire member 131 also moves in the opposite direction, and the shapes of the ends of the housing 111 and the bushing part 120 are also restored.

Therefore, the medical trocar 100 of the present exemplary embodiment may manipulate the direction of the housing 111 in such a manner as to manipulate the handle member exposed to the outside while being inserted into the body B by puncturing the skin.

Hereinafter, a medical hemostatic system 1000 using a medical trocar according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

5 and 6 schematically illustrate a hemostatic system using a medical trocar according to a first embodiment of the present invention, and FIG. 7 shows a compression part and an exterior part in a state where a medical trocar of the hemostatic system of FIG. 5 is inserted. FIG. 8 illustrates that the compression portion of the hemostatic system of FIG. 5 is expanded at a hemostatic subject site, FIG. 9 illustrates various modifications of the compression portion of the hemostatic system of FIG. 5, and FIG. 5 shows the principle that the support of the hemostatic system of the hemostatic system of FIG. 5 supports the compression part and the exterior part, and FIG. 11 shows the principle of the modification of the support of the hemostatic system of the hemostatic system of FIG. 5 supporting the compression part and the exterior part. 12 is a view illustrating a principle of fixing a support using a belt part of a hemostatic system of the hemostatic system of FIG. 5, and FIG. 13 is a pad member of the hemostatic system of FIG. 5. It shows a variant of.

5 to 13, the hemostatic system 1000 according to the first embodiment of the present invention includes a medical trocar 100, a compression unit 200, a support unit 300, a belt unit 400, The exterior part 500 includes a pressure detector 600 and a shielding part 700. However, since the medical trocar 100 is the same as the above-described structure, duplicate description thereof will be omitted.

The compression unit 200 is a structure for bleeding by being in close contact with the area inside the body (B) where the bleeding occurred, and includes an expansion unit 210 and an extension 230. The pressing unit 200 of the present invention can be implemented in various modifications, which will be described below.

The expansion portion 210 is a structure that is pressed in close contact with the bleeding area in a state inserted into the body (B), the flexible (flexible) to expand the volume by the fluid injected in the state inserted into the body (B) It is prepared with material.

Therefore, the inflation portion 210 provided with the flexible material maintains its contracted state when entering the body B, but has a structure in which the inflation portion 210 expands by the fluid injected onto the compression target region after the body B enters the body B. FIG.

Meanwhile, the expanded portion 210 in the expanded state may have various shapes and structures in consideration of the type, area, shape, degree of bleeding, etc., of the region to be pressed.

That is, although not limited, the expansion portion 210 may have a spherical shape having a constant diameter, as shown in FIG. 8, and as shown in FIG. 9, the ruptured organ O in the body B and It may be a structure (Figs. 8A, 8B, 8C) having projections at the site of contact. In this embodiment, by adjusting the thickness of the inner wall of the expansion portion 210 may be such that the expansion portion 210 in the expanded state after the fluid injection has a desired shape. That is, since the expansion portion 210 in the contracted state decreases as the thickness of the inner wall increases, the thickness of the inner wall is designed differently in consideration of the expansion rate for each part.

For example, in the present embodiment, when the expansion portion 210 has a uniform inner wall thickness, the expansion portion 210 is expanded into a spherical shape (FIG. 8) having a uniform diameter, and the expansion portion 210 has a length. When the thickness of the inner wall increases along the direction, the diameter after expansion along the longitudinal direction decreases (FIG. 9A).

On the other hand, by attaching (coating) a separate blood coagulation inducing substance 220 to the end of the expansion portion 210 in direct contact with the bleeding portion, it is preferable to maximize the blood coagulation and hemostatic effect.

The extension part 230 extends from the inflation part 210, one end of which is received in the body B, and the other end of which is exposed to the outside of the body B, and injects fluid into the expansion part 210. It functions as a passage for

On the other hand, the extension portion 230 is provided with a flexible material, but preferably has an inner wall thicker than the expansion portion 210 so as not to be deformed by the injected fluid. Therefore, the fluid injected through the extension 230 expands only the expansion unit 210, and thus the extension unit 230 does not expand.

The support part 300 is installed outside the body B and is a structure for stably fixing the pressing part 200 and the exterior part 500, and the base part 320, the pillar part 330, and the friction member. 340.

The base portion 320 is a component forming the lower portion of the support portion 300, and directly contacts the patient to perform the function of supporting the pillar portion 330 to be described later. The base portion 320 has a larger area than the pillar portion 330.

The pillar part 330 is a structure protruding from the base part 320 and is fixed in a state in which the extension part 230 is accommodated therein.

Meanwhile, the above-described support part may be manufactured in a single structure as shown in FIG. 10, but as shown in FIG. 11, separate support frames 310 manufactured as a pair face each other in an extended state 230. It may be configured as a structure to be combined.

The friction member 340 is provided on the inner wall of the pillar portion 330 in contact with the extension 230, and generates friction to limit the movement of the extension 230. In the present embodiment, the friction member 340 is provided with a rubber material having excellent workability and a relatively large coefficient of friction. However, if the friction member 340 is capable of generating frictional force by contacting the extension 230, the material of the friction member 340 may be used. It is not limited.

The belt part 400 is fixed to a part of the body B of the patient, and is for applying a fixing force so that the support part 300 does not move at a predetermined position. The strap 410, the buckle member 420, and the pad member ( 430).

The strap 410 is a band-like structure that is fixed by both ends coupled to each other in a state surrounding a part of the body (B) of the patient. On the other hand, the strap 410 is provided with a buckle member 420 to be described later in the end so that both ends can be fastened to each other.

The buckle member 420 is installed at the end of the strap 410, and is an auxiliary structure for fastening both ends of the strap 410. The strap 410 may be tightly fixed to a part of the body B of the patient by engaging the buckle member 420 having the end installed at the opposite end.

The pad member 430 is engaged with the strap 410 to be disposed on a path through which the structures of the pressing part 200 and the exterior part 500 enter, that is, the perforated area, to substantially fix the support part 300. .

The pad member 430 has a through hole 440 having a size corresponding to the diameter of the pillar portion 330, and the base portion 320 is interposed between the pad member 430 and the patient, and the pillar portion 330 is provided. ) Is protruded from the through hole 440, the pad member 430 is in close contact with the patient, and is fixed to the base portion 320 interposed therebetween.

On the other hand, as shown in Figure 13, in the modification of the present embodiment, the pad member 430 'is made of a plastic material, the bottom is formed with a dome-shaped recessed space for accommodating the base portion 320. The upper end portion of the recessed space, that is, the through-hole area is formed to be in line contact with the extension 230.

According to this modification, the support part 300 and the pressing part 200 and the exterior part 500 fixed thereto are firmly supported in the recessed space of the pad member 430 'with the base part 320 received therein. It can be tilted and fixed while maintaining the angle.

The exterior part 500 is integrally wrapped with the pressing part 200 and is provided to provide a certain rigidity so that the pressing part 200 is smoothly inserted into the trocar 100, and the post member 510 and the connecting member ( 520).

The post member 510 surrounds a part of the extension part 230, but is not limited thereto, and thus the post member 510 is inserted together with the extension part 230 in the human body, and thus, the post member 510 is preferably made of a plastic material having a predetermined rigidity.

A fluid flow port 511 is formed in the post member 510, and the fluid flow port 511 is connected to a passage through which fluid flows in the extension part. Therefore, the fluid may be injected into the pressing unit 200 through the fluid flow port 511, or the fluid may be discharged from the pressing unit 200.

The connection member 520 is in close contact with the expansion member 210 in a state where the end is foldably coupled to the post member 510. Therefore, the connecting member 520 is arranged in the same direction as the post member 510 when the expansion unit 210 contracts, but the expansion unit 210 when the expansion unit 210 expands as a predetermined fluid is injected. Unfolds with).

The pressure detector 600 is connected to the fluid flow port 511 to detect the pressure of the fluid in the pressing unit 220. Ports for injecting and discharging fluid may be separately formed at the end of the pressure detector 600.

However, the pressure detector 600 may not be used if necessary in the present invention. In particular, when the pressure detector 600 is not provided, a device such as a blood pressure monitor may be installed in the fluid flow port to inject the fluid.

One end of the shield 700 is connected to the end of the trocar 100, the other end is coupled to one region of the post member 510, and accommodates the exterior portion therein, the pressing portion 200 and the exterior The part 500 is to prevent contact with foreign matter in the process of being inserted into the human body in advance.

Hereinafter, the principle of the patient hemostatic method using the medical hemostatic system using the medical trocar according to the first embodiment of the present invention will be described in detail with reference to FIGS. 5 to 13.

First, when bleeding occurs in the body (B), the operator drills an area where the bleeding is predicted using the medical trocar 100. When the perforation is completed by the medical trocar 100, the operator manipulates the handle member 133 so that the direction of the end of the medical trocar 100 faces the point where the bleeding is predicted.

Next, the exterior part 500 and the compression part 200 accommodated therein enter the trocar 100 into the medical trocar 100. In this case, as shown in FIG. 6, since the shielding part 700 is connected to the medical trocar 100 and the exterior material 500, the pressing part 200 and the exterior part 500 are accommodated in the entry process. External foreign matters are blocked from reaching the inside. Therefore, by the above-described process, the pressing unit 200 is guided by the medical trocar 100 to prevent bleeding, and thus bleeding occurs. The location can be reached easily.

In addition, when only the flexible pressing unit 200 enters the medical trocar 100, it is difficult to operate due to the nature of the material. However, in the present embodiment, the flexible pressing unit 200 and the outer portion 500 having rigidity surrounding the pressing unit 200 are rigid. Since the unitary structure enters the medical trocar 100, more convenient operation is possible. If the end of the pressing portion 200, that is, the expansion portion 210 is found to have reached the bleeding occurrence position, the post member A predetermined fluid is injected into the pressing unit 200 through the fluid flow port 511 formed at 511. As shown in FIGS. 7 and 8, the fluid is injected through the fluid flow port 511 to expand the inflation portion 210, and the inflation portion 210 bleeds by inflating at different inflation rates according to the thickness of each part. By tightly compressing the site, hemostatic function of the bleeding site is performed. On the other hand, since the pressure in the pressing unit 200 can be measured in real time through the pressure detector 600 in the fluid injection process, it is possible to inject the appropriate amount of fluid. However, when the pressure detector 600 is not mounted, air may be injected while real-time measuring the pressure in the compression unit 200 using a commercially available electronic blood pressure monitor.

At this time, as shown in FIG. 8, as the expansion unit 210 expands, the connection member 520 connected to the end of the post member 511 is expanded together with the expansion unit 210 to firmly secure the expansion unit 210. It functions as a supporting structure.

When the entry of the integrated structure consisting of the pressing portion 200 and the outer portion 500 in the body (B) is completed, the medical trocar 100 is separated from the pressing portion 200 and the outer portion 500 structure for medical use. The trocar 100 is completely decontacted from the patient.

At the same time, as shown in FIG. 10, the support part 300 is positioned on the perforation area in the state in which the extension part 230 and the post member 510 surrounding it are accommodated in the pillar part 330. 320) close to the patient. The extension part 230 and the post member 510 surrounding the extension part are in close contact with the friction member 340 in the pillar part 330 and are fixed by restricting movement in the longitudinal direction by the friction force.

In this case, as shown in FIG. 11, when the support part 300 has a form in which a pair of support frames 310 are coupled to each other, the separated pair of support frames 310 respectively face the extension part 230. Since the fixing force can be generated by the method of mutual coupling in the state, it is relatively easy to work than inserting the extension 230 in the support 300 is composed of a single structure.

Next, as shown in FIG. 12, the pad member 430 is disposed on the perforation area of the patient so as to position the pillar part 330 through the through hole 440. The base portion 320 having a larger area than the through hole 330 does not leave the pad member 430 and is interposed between the pad member 430 and the patient. The strap 410 is tightly fixed to the patient by engaging the both ends by using the buckle member 420 while the strap 410 is wrapped around a part of the patient's body (B).

Due to the fixing of the strap 410, the pad member 430 is in close contact with the patient, and the support part 300 including the base part 320 positioned between the pad member 430 and the patient is also restricted in movement in the perforation region. It is fixed.

Therefore, according to the present embodiment, by pressing the bleeding site in a manner that expands the small volume of the compression unit 200 in the body (B) in the contracted state at the time of bleeding in the body (B), separate equipment It has the advantage of being able to act quickly without it.

In addition, by firmly fixing the pressing unit 200 by using a structure outside the body (B), there is an effect that can reliably press the bleeding site.

According to the present embodiment, the bleeding site can be pressed not only by simple contact pressure, but also in the form of wrapping blood vessels (V), and smooth measures are possible in response to various organ (O) ruptures.
