DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an integrated disposable clip for a disposable medical endoscope according to the present invention will be described in detail with reference to the accompanying drawings. The following examples are illustrative of the present invention but are not intended to limit the present invention.

The integrated disposable clip device for an endoscope according to the present invention is an improved device based on the endoscope treatment instrument system of the above-mentioned Japanese Patent No. 10-0832957, and includes an insertion tube 10, An operation unit 30, a clip 40, a connecting member 50, and a pressure pipe 60. [

The insertion tube 10 is a flexible tubular member that is inserted into the channel of the endoscope as shown in Figs. 1 and 6 to 8. That is, the insertion tube 10 is formed of a flexible material so that it can be bent according to the curvature of the channel of the endoscope. In addition, in order to reduce the manufacturing cost according to the characteristics of the clip treatment device 1 according to the present invention, All or most of the insertion tube 10 may be formed of a plastic synthetic resin.

The insertion tube 10 is formed such that the wire 20 has an inner diameter capable of freely moving forward and backward. When the insertion tube 10 is formed of a plastic synthetic resin, a metal ring 11 made of a metal material rather than a plastic synthetic resin is assembled (attached and bonded) to the tip of the insertion tube 10, ) Can be surely pushed.

The wire 20 is a rod-shaped member that is inserted into the insertion tube 10 freely forward and backward movably, as shown in Figs. 1 and 6-8. The wire 20 is formed of a flexible material so as to be freely bent in accordance with the bending of the insertion tube 10 and is also used for disposing the clip 20 ) May be formed of a plastic synthetic resin.

1, the manipulation unit 30 is a mechanism for manipulating the wire 20 back and forth with respect to the insertion tube 10 and rotating it.

The operation unit 30 includes a main body 31 formed with slits 31a and the like, a slider 32 for rotating the wire 20 back and forth and a grip ring 32 for gripping the finger when operating the slider 32 33 and the like. The clincher is constructed in such a manner that the practitioner can operate the wire 20 forward and backward and rotate with respect to the insertion tube 10, and the disposable clip treatment device 1 The operation section 30 can be formed of a plastic synthetic resin in order to reduce the manufacturing cost. The specific configuration and operation of the example of the operation unit 30 can be found in the above-mentioned conventional Patent No. 10-0832957.

The clip 40 is a clamp member made of, for example, stainless steel, which is formed so as to be openable and closable so as to have an elasticity to grip the living tissue.

2 and 3, the clip 40 is formed by bending an elongated elastic strip member in a shape of a letter alpha (alpha) so as to have a central loop portion 41 and two arm portions 42 The arm portion 42 is further opened and the arm portion 42 is closed when the loop portion 41 is pressed so that the living body tissue 3 can be gripped. The specific structure and operation of the clip 40 can be found in the above-mentioned conventional Patent No. 10-0832957.

The connecting member 50 is a long elongated rod-shaped member made of a plastic synthetic resin material, as shown in FIGS. 2 and 4, etc., having a clip 40 at one end and a wire 20 at the other end . The connecting member 50 is provided with a rupture portion 51 that is broken when a tension greater than a certain level is applied thereto.

2 and 4, the engaging piece 52 is formed at one end (left end) of the connecting member 50 and the engaging piece 50 The clips 40 can be coupled to the connecting member 50 by hooking the loop portion 41 of the clip 40 to the connecting members 50 and 52.

The insertion tube 110, the wire 120, and the operation unit 130 are used repeatedly in the case of the conventional endoscope clip treatment apparatus illustrated above. The disposable connecting member 220 is used after the use of the wire 120 The connection between the wire 120 and the connecting member 220 is required to be removed from the distal end of the connecting member 220. For example, as shown in Figs. 9 and 10, The clip handling device 1 according to the present invention is applied to the disposable device such that the connecting member 50 is connected to the wire 20 So that the other end of the connecting member 50 and the distal end of the wire 20 do not need to be detachably coupled.

In the case where the wire 20 is formed of a plastic synthetic resin, both the wire 20 and the connecting member 50 are formed of a plastic synthetic resin, but since they have different functional characteristics, Since it is not easy, it may be preferable to separately form and then bond the components using plastic synthetic resins having different physical properties. The wire 20 and the connection member 50, which are separately formed, may be formed of, for example, Or they can be firmly coupled to each other by a structural coupling such as a fit or by a combination of these.

2 and 4, at the other end of the connecting member 50, an engaging hole 53 having a diameter smaller than the diameter of the wire 20 is formed at the other end of the connecting member 50 A coupling protrusion 21 having a diameter and a length corresponding to the coupling hole 53 is formed at the distal end of the wire 20 so that the coupling protrusion 21 is inserted into the coupling hole 53, The connection member 50 and the wire 21 can be separated from each other unnecessarily. At this time, the outer diameter of the connection member 50 and the wire 20 connected to each other by the coupling hole 53 and the coupling protrusion 21 are formed to be the same, so that an undesirable step is not formed.

Of course, as the coupling structure of the connecting member 50 and the wire 20 of the clip treatment apparatus of the present invention, the connecting portion 121 of the arrowhead shape capable of being detached (detachable) as in the above-described conventional Patent No. 10-0832957, Application of a hook-slit engagement structure such as the slit 221 is not excluded. However, even if the hook-and-slit coupling structure is applied to the present invention, the coupling structure is only for coupling (assembling) the wire 20 to the coupling member 50, ). ≪ / RTI >

In the case of forming the rupture portion 51 in the connecting member 50, for example, as shown in the illustrated embodiment, the rupture portion 51 having a smaller diameter than the other portion at about the middle of the connecting member 50, The breaking portion 51 (neck portion) can be broken when a tensile force of a predetermined magnitude or more is externally applied. It is also possible to form the breaking portion 51 at another position such as the left end of the connecting member 50 as long as the position of the breaking portion 51 does not interfere with other actions of the connecting member 50.

The breaking portion 51 is formed on the connecting member 50 when the connecting member 50 is pulled through the wire 20 after clipping the biotissue with the clip 40 as described later, 51 are broken so that the clip 40 and a part of the connecting members 50 remain in a state holding the living tissue and the remaining connecting members are collected together with the wires.

As shown in Fig. 5, the pressure pipe 60 is a tubular member having an elastic catching blade 61 formed on its periphery. The pressure tube 60 is biased to the left side of the connecting member 50 until the biotissue 3 is clipped to the clip 40 as shown in Figures 2 and 6, It is in position. However, as will be described later, in the process of gripping the living tissue 3 with the clip 40, the pressure tube 60 is moved to the position where it is fitted around the clip 40, and when the moved pressure tube 60 is opened By pressing the clip 40 to close the clip 40, the clip 40 grasps the living tissue 3 and the pressure tube 60 keeps the clip 40 in the closed state.

5, the front end ring 62 of the metal material is assembled to the front end of the pressurizing pipe 60, so that a clip (not shown) of the pressurizing pipe 60 is formed, It is possible to enhance the pressing action of the pressing member 40.

The restricting projection 54 protruding from the substantially middle position of the connecting member 50 is located between the clip 40 and the pressure tube 60 in a state where the pressure tube 60 is not shifted to the right side of the connecting member 50 It is a limiting projection.

When the pressure tube 60 is positioned in the insertion tube 10, the retaining blade 61 of the pressure tube 60 is elastically folded in. However, when the pressure tube 60 comes out of the insertion tube 10, When the wire 20 is retracted in this state, the retaining vane 61 is caught by the tip of the insertion tube 10 (for example, the metal ring 11) 60 can not be inserted into the insertion tube 10 so that the pressure tube 60 is moved from the circumferential position of the connecting member 50 to the circumferential position of the clip 40 while closing the clip 40, .

9 has a distal end portion 111 that is enlarged to have an inner diameter (2 mm) rather than an inner diameter (for example, 1 mm) of another portion on the distal end of the insertion tube 110, The clip 210, the connecting member 220 and the pressurizing pipe 230 having an outer diameter larger than that of the wire 120 are accommodated in the distal end portion 111 in such a manner that they can be moved forward and backward. Although the device 1 is not completely excluded from forming the enlarged tip portion in the insertion tube 10 as in the conventional art, the insertion tube 10 applied to the present invention does not form the enlarged tip portion, 10 is formed to have an inner diameter (for example, about 2 mm) such that the clip 40, the connecting member 50, and the clip assembly 2 of the pressure tube 60 are received and moved back and forth The outer diameter of the wire 20 applied to the conventional endoscope clip treatment device Even greater motivation - can be formed (for example, approximately 1.5mm 1.8mm).

In this way, the inner diameter of the entire insertion tube 10 is enlarged in the same manner without forming the distal end portion separately enlarged in the insertion tube 10, and the outer diameter of the wire 20 is formed in the insertion tube 10 The enlargement of the tube 20 as large as possible is to eliminate the complicated process of forming the tip end portion of the insertion tube 10 and to strengthen the strength of the insertion tube 10 and the wire 20 when they are formed of a plastic synthetic resin material, In order to reduce the excessive radial clearance of the wire 20 in the insertion tube 10.

Hereinafter, a method of using the integrated disposable clip-use device 1 for an endoscope according to the present invention will be described with reference to Figs. 6 to 8. Fig.

6A, the clip treating apparatus 1 of the present invention is characterized in that the connecting member 50 is coupled to the distal end of the wire 20 and the clip 40 is coupled to the connecting member 50 And the clip assembly 40 of the clip 40 and the connecting member 50 and the clip assembly 2 of the pressure tube 60 are inserted into the insertion tube 10 with the pressurizing pipe 60 fitted around the connecting member 50 And sterilized and packaged in a state of being accommodated in the distal end and provided to the operator.

In order to use the clip treatment apparatus 1 of the present invention, the practitioner first removes the wrapping paper, inserts the insertion tube 10 into the channel of the endoscope, makes the tip of the insertion tube 10 close to the affected part, The manipulation unit 30 is operated to advance the wire 20 so that the clip assembly 2 is pulled out of the insertion tube 10 and the folded clip 40 is opened to open.

Next, when the wire 20 is retracted by operating the operation unit 30, the clip assembly 2 is retracted as a whole, but the tip end (e.g., the metal ring 11) of the insertion tube 10 The clip assembly 2 is retracted only to the position where the engaging blade 61 is engaged (see Fig. 7C).

Next, when the wire 20 is further retracted by operating the operating portion 30, the engaging blades 61 are engaged with the tip of the insertion tube 10 (e.g., the metal ring 11) Is moved around (moved) to the circumferential position of the loop portion 41 of the clip 40 at the periphery of the connecting member 50 so that the pressurizing pipe 60 presses the loop portion 41, (See D in Fig. 7).

Next, the position of the insertion tube 10 is finely adjusted, the wire 20 is rotated to accurately position the opened clip 40 on the biotissue 3 to be sewn, The pressing tube 60 with the engaging blade 61 at the tip end of the insertion tube 10 is pushed around (moved) around the clip 40 around the connecting member 50, , So that the pressure tube 60 presses and closes the clip 40 so that the clip 40 grasps (clips) the biotissue 3 (see FIG. 8E).

Next, when the wire 20 is further retracted by operating the operating portion 30, the breakage portion 51 of the connecting member 50 is broken, whereby the clip 40 is pressed by the pressure tube 60 The tissue remains in the living body while holding the tissue, and a part of the connecting member 50 flows into the insertion tube 10 while being coupled to the wire 20 (see F in Fig. 8). At this time, the magnitude of the breaking force required for breaking occurring at the breaking portion 51 of the connecting member 50 is set to such a force as not to damage the holding state of the living tissue by the clip 40.

Finally, the clip treatment device 1 of the present invention, in which only the insertion tube 10, the wire 20, the manipulation part 30 and a part of the connecting member 50 are left, is removed from the channel of the endoscope, (See G in Fig. 8).
