Description

[Technical field]

[0001] The present invention relates to a clip, and more particularly to a clip used for medical purposes such as in surgery. [Background technology]

[0002] In cardiac surgery, the epidermis of the heart is clamped with clips to supply electrical signals to pace the heart. Currently, so-called alligator clips are often used to clamp the epidermis of the heart.

[0003] Alligator clips have a pair of jagged edges on each end, like the mouth of an alligator, which combine to make them less likely to slip off the object they are holding. This is why they are so commonly used in scientific experiments. However, when used on human organs such as the heart, there is a risk that the jagged edges may damage the skin.

[0004] As a clip that can be used in surgery other than the alligator clip, for example, there is a technique described in Patent Document 1 below. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Publication number 05-030736 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the example of the technology described in Patent Document 1, a long distance must be secured to the tip, and the clamping force is weak, so there is a risk of the device slipping off during surgery. In addition, there is also a problem with supplying the electrical signal for pacing.

[0007] In view of the above problems, the present invention aims to provide a clip that can stably transmit electrical signals while reducing the risk of damaging organs or slipping off during surgery. [Means for solving the problem]

[0008] A clip according to one aspect of the present invention which solves the above-mentioned problems comprises a first base member, a first conductive plate member supported by the first base member, a second conductive plate member whose tip is overlapped with the first conductive plate member, and a second base member arranged to cover the second conductive plate member and rotatably supported on the first base member via an axis member, and the second base member adjusts the clamping force between the first conductive plate member and the second conductive plate member by sliding relative to the first base member.

[0009] In addition, in this respect, although not limited thereto, it is preferable that the first conductive plate member and the second conductive plate member are each formed of a single leaf spring.

[0010] Also, in this respect, although not limited thereto, it is preferable that a long hole is formed in the second base member along the longitudinal direction, the shaft member passes through the long hole, and the shaft member moves within the long hole to achieve sliding.

[0011] In addition, in this respect, although not limited thereto, it is preferable to include a conductive wire connected to the first conductive plate member and the second conductive plate member.

[0012] In addition, in this respect, although not limited thereto, it is preferable that a convex portion is provided near at least one of the front end of the first base member and the front end of the second base member.

[0013] In addition, in this respect, although not limited thereto, it is preferable that an anti-slip mechanism is provided near the tip of at least one of the first conductive plate member and the second conductive plate member.

[0014] In addition, in this respect, although not limited thereto, it is preferable that a through hole is formed near the tip of at least one of the first conductive plate member and the second conductive plate member. Effect of the Invention

[0015] As described above, the present invention makes it possible to provide a clip that can stably transmit electrical signals while reducing the risk of damaging organs or slipping off during surgery. [Brief description of the drawings]

BEST MODE FOR CARRYING OUT THEINVENTION

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention can be embodied in many different forms, and is not limited to the specific examples described in the following embodiments.

[0018] 1 is a schematic diagram of a clip according to this embodiment (hereinafter referred to as "this clip") 1. As shown in this diagram, this clip 1 is a clip including a first base member 2, a first conductive plate member 31 supported by the first base member 2, a second conductive plate member 32 whose tip is overlapped with the first conductive plate member 31, and a second base member 5 arranged to cover the second conductive plate member 32 and rotatably supported by the first base member 2 via a shaft member 4, and the second base member 5 adjusts the clamping force between the first conductive plate member 31 and the second conductive plate member 32 by sliding relative to the first base member 2.

[0019] By adopting such a configuration, the present clip 1 can be used as a medical clip that can gently clamp an organ during surgery etc., reduce the risk of damaging the organ or of it slipping off during surgery, and can stably transmit electrical signals to the organ. The specific configuration and effects of the present clip 1 will be described in detail below.

[0020] As described above, the first base member 2 in the present clip 1 supports the first conductive plate member 31, the shaft member 4, the second base member 5, etc., and is one of the members constituting the main framework of the present clip 1. Fig. 2 is a diagram showing an outline of the first base member 2 in the present clip 1.

[0021] As described above, the first base member 2 of the present clip 1 supports the first conductive plate member 31. More specifically, it supports, and preferably fixes, the first conductive plate member 31.

[0022] Furthermore, the first base member 2 of the present clip 1 is preferably, but not limited to, equipped with a bottom member 21 that extends elongatedly in one direction (hereinafter also referred to as the "extension direction"), and sidewall members 22 formed along the extension direction on both sides of the bottom member 21. Providing the bottom member 21 makes it possible to stably hold the above-mentioned first conductive plate member 31, and providing the sidewall members 22 makes it possible to pass the shaft member 4 through, while preventing the first conductive plate member 31 from slipping off, and furthermore, as will become clear from the description below, it is possible to prevent the second base member 5 from slipping sideways (in a direction perpendicular to the extension direction) while sliding.

[0023] Furthermore, the specific structure of the first base member 2 of the clip 1 supporting the first conductive plate member 31 is not particularly limited, but for example, it is preferable that a through hole 211 for inserting the first conductive plate member 31 is formed in the bottom member 21. Providing the through hole 211 has the advantage that the first conductive plate member 31 is more unlikely to slip and is fixed more stably.

[0024] In addition, the first base member 2 of the clip 1, more specifically, the side wall member 22, is formed with a shaft member hole 221 through which the shaft member 4 passes. This allows the shaft member 4 to pass through and allows it to be integrated with the second base member 5.

[0025] The material of the first base member 2 in the present clip 1 is not limited as long as it can exert the effects described above, and may be metals such as aluminum, titanium, and iron, or resins such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polyvinyl chloride (PV), polycarbonate (PC), and silicone. In particular, it is preferable to make the first base member 2 of a resin transparent (having a light transmittance of 60% or more in the visible range), since it is easy to see if the present clip 1 is dirty, such as when the patient's blood is attached during surgery. In the case of resin, it is preferable that it can be sterilized, and more preferably that it has heat resistance. In addition, in the case of metal, it is preferable to form an insulating coating so that the user of the present clip 1 does not get an electric shock when holding it.

[0026] This clip 1 has a first conductive plate member 31 that is supported, preferably fixed, to a first base member 2. Being supported by the first base member 2 makes it possible to stably clamp (hold) a patient's organs together with the second base member 5.

[0027] The material of the first conductive plate member 31 in the clip 1 is not limited as long as it has conductivity, and is preferably a metal such as aluminum, titanium, iron such as stainless steel, or copper.

[0028] On the other hand, this clip 1 has a second conductive plate member 32 whose tip is overlapped with the first conductive plate member 31. As is clear from the above description, the second conductive plate member can be paired with the first conductive plate member to clamp an organ of a patient or the like.

[0029] The material of the second conductive plate member 32 is the same as that of the first conductive plate member 31 described above, and its description is omitted, but when the first conductive plate member 31 and the second conductive plate member 32 are made of different materials, they may be made of the same material or different materials.

[0030] In addition, in the present clip 1, although not limited thereto, it is preferable that the first conductive plate member 31 and the second conductive plate member 32 are configured by a conductive plate member 3 made of a single leaf spring. An example of the case of a single leaf spring is shown in Fig. 3. By using a conductive plate member 3 made of a single leaf spring, it is possible to easily manufacture the clip, and the first plate member 31 and the second conductive plate member 32 can be securely fixed by the bent portion 33, and an appropriate clamping force can be achieved.

[0031] On the other hand, when the first conductive plate member 31 and the second conductive plate member 32 of the clip 1 are made of different members, it is preferable to provide, for example, a repulsive elastic member 34 on the end side (the side opposite to the tip side) of the first conductive plate member 31 and the second conductive plate member 32. An image of a cross section in this other case is shown in FIG. 4. By doing so, an appropriate repulsive force is imparted to the tip side of the first conductive plate member 31 and the second conductive plate member 32, and an appropriate clamping force (clamping force) is imparted. In this case, the elastic member 34 may be a leaf spring, but a coil spring is preferable for simplicity.

[0032] In addition, in this clip 1, although not limited thereto, it is preferable that through holes 311, 321 are formed near the tip of at least one of the first conductive plate member 31 and the second conductive plate member 32. By providing the through holes 311, 321, when an organ is clamped, flesh of the organ bulges into the through holes 311, 321, and this bulged portion serves to prevent the first conductive plate member 31 and the second conductive plate member 32 from slipping.

[0033] The shapes of the through holes 311, 321 formed in the first conductive plate member 31 and the second conductive plate member 32 of the clip 1 are not limited as long as they have the above-mentioned functions, but are preferably circular, elliptical, or rounded polygonal (polygonal with rounded corners). The rounded corners have the advantage of making it possible to build up the tissue of the patient without damaging it. The size of the through holes can be adjusted as appropriate and is not limited, but it is preferable that the shortest hole diameter is 2 mm or more. In addition, when the hole shape is elliptical or the like, it is preferable that the major axis of the ellipse is approximately parallel to the extension direction.

[0034] In addition, in this clip 1, although not limited thereto, it is preferable that anti-slip mechanisms 312, 322 are provided near the tip of at least one of the first conductive plate member and the second conductive plate member, more specifically, on the surfaces where the first conductive plate member 31 and the second conductive plate member 32 face each other. An image of this case is shown in Fig. 5. Note that this figure shows the surface of one of the conductive plate members, but these may be provided on both.

[0035] As shown in the figure, the structure of the anti-slip mechanisms 312 and 322 can be various, for example, multiple small protrusions or a roughened surface, which can be adjusted as appropriate. Also, they can be combined with the through holes as described above.

[0036] The second base member 5 is disposed so as to cover the second conductive plate member 32 and is rotatably supported on the first base member 2 via a shaft member 4. A schematic diagram of the second base member 5 is shown in FIG.

[0037] Furthermore, the second base member 5 of the clip 1 is preferably, but not limited to, provided with a bottom member 51 extending elongatedly in one direction (hereinafter also referred to as the "extension direction") and sidewall members 52 formed along the extension direction on both sides of the bottom member 51. Providing the bottom member 51 makes it possible to stably hold the second conductive plate member 32, and providing the sidewall members 52 makes it possible to provide a hole through which the shaft member 4 passes and prevents the second conductive plate member 32 from slipping off, and furthermore, due to the regulation by the sidewall members 22 of the first base member 2, it is possible to prevent the second conductive plate member 32 from slipping sideways (perpendicular to the extension direction) even if it slides.

[0038] The second base member 5 adjusts the clamping force between the first conductive plate member 31 and the second conductive plate member 32 by sliding relative to the first base member 2. Images of this case are shown in Figures 7 and 8. Figure 7 shows the clamping force in a normal state, while Figure 8 shows the clamping force in a state where it is stronger than the normal state. In this way, this clip makes it possible to strengthen the clamping force by sliding the second base member 5 and pressing down on the first conductive plate member 31.

[0039] In addition, in the present clip 1, although not limited thereto, it is preferable that a long hole is formed in the second base member 5 along the longitudinal direction, the shaft member 4 passes through the long hole, and the shaft member 4 moves within the long hole to achieve sliding. This relationship may be reversed in the first base member 2 and the second base member 5. That is, the first base member 2 may be provided with a long hole along the longitudinal direction. However, since the long hole is easily clogged with dirt, blood, etc., it is preferable that the long hole is provided on the base member side of the side wall member closer to the inside (the center side of the bottom member). In this way, the side wall member of the other base member acts as a barrier, and there is an advantage that dirt, etc. are less likely to get mixed in even if a long hole is provided.

[0040] The material of the second base member 5 in the present clip 1 is not limited as long as it can exhibit the effects described above, and may be metal such as aluminum, titanium, iron, or resin such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), silicone, or PEEK resin. In particular, it is preferable to make the second base member 5 of resin transparent, since it is easy to see if the present clip 1 is dirty, such as when the patient's blood is attached during surgery. In addition, in the case of metal, it is preferable to form an insulating coating so that the user of the present clip 1 does not get an electric shock when holding it.

[0041] In addition, in the present clip 1, although not limited thereto, it is preferable that a protrusion is provided at least in the vicinity of the tip of the first base member and in the vicinity of the tip of the second base member, more preferably on the surface side facing the other base member. By providing a protrusion in this manner, one conductive plate member can be brought into contact with the other conductive plate member at a larger angle, which has the advantage of making the clamping force stronger.

[0042] In addition, in the present clip 1, although not limited thereto, it is also preferable to provide a convex portion near the tip of the second base member or the tip of the first base member. By forming a convex portion, the user can easily press the finger against the convex portion, and the second base member can be easily slid. The size of the convex portion may be a mountain shape as shown in the above figure, but the size and shape are not particularly limited.

[0043] Furthermore, the present clip 1 preferably includes, but is not limited to, a conductive wire 6 connected to the first conductive plate member and the second conductive plate member.

[0044] As described above, this clip makes it possible to stably transmit electrical signals from an organ while reducing the risk of damaging the organ or of it slipping off during surgery. [Industrial Applicability]
