Foreign body removal forceps

Abstract

The present invention provides a foreign body removal forceps that can easily grasp or scoop up small foreign objects attached to affected areas such as the cornea, and that allow for visual inspection of the foreign object while it is grasped, without the foreign object easily detaching. [Solution] This foreign object removal forceps 1 comprises a pair of handles 2 joined at their terminal ends 21, and storage sections 3 provided at the tip of each handle. The storage sections are hemispherical in shape, with their opening surface 33 facing the opening surface of the other storage section, and each storage section having a viewing window 371. When the opening surfaces of each storage section are brought into contact with each other, they form a container structure. The container structure has a viewing window formed by combining the viewing windows 371 in a part of the upper part of the storage section, allowing the inside of the container structure to be seen. This restricts the upward movement of the foreign object 7 from the storage section 3 and prevents the foreign object from falling out from above. Furthermore, the foreign object can be grasped while it is contained in the storage section.

Description

Technical Field

[0001] The present invention relates to a foreign object removal forceps for removing foreign objects adhering to an affected area. More specifically, it relates to a foreign object removal forceps that can easily pick up or scoop up small foreign objects adhering to an affected area such as the cornea, and can visually recognize the foreign object while maintaining a stable clamping state.

Background Art

[0002] Conventionally, forceps have sometimes been used to remove small foreign objects adhering to an affected area such as the cornea (see, for example, Patent Documents 1 and 2). The removal of foreign objects by forceps is performed by sandwiching and pulling out or scraping off the foreign object at the tip of the forceps. In addition, providing grooves that fit together (see Patent Document 1) or gripping so as to store the foreign object in a storage portion (see Patent Document 2) has been considered to facilitate clamping of small foreign objects. In particular, when the foreign object is stored in the storage portion, it is suitable for the foreign object removal operation because the foreign object is less likely to fall off.

Summary of the Invention

Problems to be Solved by the Invention

[0004] On the other hand, during foreign body removal procedures, it is required to visually confirm the foreign body removed from the affected area immediately after removal. However, when the foreign body is placed inside a storage compartment, the walls of the compartment may obstruct the view of the foreign body, making it impossible to confirm its appearance. Also, while it is easier to confirm the appearance of the foreign body when it is held in place, depending on the shape of the foreign body, stable gripping may not be possible, and it may easily fall out. For this reason, there is a need for a method that allows the appearance of the foreign body to be confirmed while it is placed inside a storage compartment and does not easily fall out. The present invention has been made in view of the above circumstances, and aims to provide a foreign body removal forceps that can easily grasp or scoop up small foreign bodies adhering to affected areas such as the cornea, and that allows the foreign body to be visually observed while being grasped, without the foreign body easily detaching.

The foreign body removal forceps according to 5., wherein the pointed tip is located above the opening surface. [Effects of the Invention]

[0006] The foreign object removal forceps of the present invention comprises a pair of handles joined at their terminal ends, and a storage section formed at the tip of each handle, wherein the storage section is hemispherical in shape, its opening surface facing the opening surface of the other storage section, and is equipped with a viewing window, and when the opening surfaces of each storage section are brought into contact with each other, a container structure is formed, and the container structure is equipped with a viewing window formed by combining the viewing windows on a part of the upper part of the storage section, which allows the inside of the container structure to be seen, so that foreign objects can be gripped while they are contained in the storage section, and the contained foreign objects do not easily fall out of the storage section. Furthermore, this foreign body removal forceps comprises a pair of handles joined at their terminal ends, a storage section formed at the tip of one of the handles, and an opening lid formed at the tip of the other handle. The storage section is hemispherical in shape, its opening surface faces the opening lid, and it has a viewing window. When the opening surface is covered by the opening lid, a container structure is formed with a viewing window in a part of the upper part of the storage section. The container structure has a viewing window in a part of the upper part of the storage section, which is made up of the viewing window and allows the inside of the container structure to be seen. Therefore, foreign bodies can be gripped while stored in the storage section, and the stored foreign bodies will not easily fall out of the storage section. Furthermore, the storage section and opening lid allow for the gripping of foreign objects, and the edges of the opening surface allow for scooping and scraping, enabling procedures such as extraction, polishing, and curettage. In particular, the storage section has a hemispherical shape that makes it easy to scoop like a spoon, so when gripping a foreign object, it can be tightly fitted to the affected area without any gaps. Even if the foreign object is embedded in the affected area, it can be inserted between the foreign object and the affected area, securely gripping the base of the foreign object, scooping it up, or scraping it off, thus eliminating the possibility of leaving any foreign object behind. Furthermore, with the foreign object contained within the storage compartment, the container structure formed by the storage compartment can be visually inspected and observed through the viewing window above the storage compartment. The viewing window is formed only in a portion of the upper part of the storage compartment, and other parts above the storage compartment include a lid or wall that covers the inside of the storage compartment from above. Therefore, even if the foreign object moves to the upper part of the storage compartment, its movement is restricted by the aforementioned lid or wall, and the foreign object will not detach from the upper part of the storage compartment during observation.

[0007] If the upper part of the storage section includes a visual window section, which is a visual groove with an opening that contacts the opening surface, and a cover section formed along the periphery of the visual window section and covering the lower part of the storage section, then even if a foreign object stored in the upper part of the storage section moves, it will come into contact with the cover section, which acts as a lid or wall, restricting its upward movement and preventing the foreign object from falling out of the storage section. Furthermore, because the storage section is surrounded by the cover section, the inside of the storage section can be observed through the visual window located in the center of the upper part of the storage section, allowing the foreign object to be visually inspected without it detaching from the storage section while being held. In addition, because the visual window is located in the center of the upper part of the storage section, the entire inside of the storage section is easily observable.

[0008] If the viewing window is rectangular or elliptical with its major axis aligned with the opening surface, a wide area of ​​the storage section can be viewed through the window along the major axis. Furthermore, by having a minor axis portion in the window, it becomes difficult to obtain the necessary size for the foreign object to escape from the viewing window, and the entire foreign object can be viewed without it escaping from the storage section while being held.

[0009] If the front end of the opening surface of the storage section is further equipped with a pointed tip, foreign objects can be dug up, scooped up, or gouged out by the pointed tip, making the foreign object removal process easier. In particular, it is possible to dig up and remove foreign objects such as rust that remain in the affected area, and the removal of iron fragments as foreign objects and the removal of rust caused by those iron fragments can be carried out continuously without changing the tool.

[0010] When the pointed tip is positioned above the opening, the tip used to scoop up or gouge out foreign objects is positioned above the storage section of the forceps, so it is not hidden by other parts of the forceps. This allows the tip to be visually seen without being obscured by other parts when using the pointed tip, and does not hinder its use, making it suitable. Furthermore, when storing foreign objects in the storage section, the tip of the pointed tip can be prevented from coming into contact with the treatment surface and causing injury.

Mode for Carrying Out the Invention

[0012] The matters shown here are illustrative and for exemplarily explaining the embodiments of the present invention, and are described for the purpose of providing what is considered to be the most effective and easy-to-understand explanation of the principles and conceptual features of the present invention. In this regard, it is not intended to show the structural details of the present invention more than is necessary for a fundamental understanding of the present invention, and it is to clarify to those skilled in the art how some forms of the present invention are actually embodied by the description in combination with the drawings.

[0013] As illustrated in Figures 1 to 8, this foreign body removal forceps 1 comprises a pair of handles 2 joined at their terminal ends 21, and a storage section 3 formed at the tip 24 (the tip of the handle end 23) of each handle 2. Furthermore, each handle 2 may be provided with a storage section 3 formed at the tip 24A of one handle 2A and an opening cover 5 formed at the tip 24B of the other handle 2B. Furthermore, one or both of the storage compartments 3 may be equipped with a pointed tip 4 at their tip end.

[0014] The foreign body 7 that this foreign body removal forceps 1 grasps or scrapes off is approximately 0.05 mm to 2 mm in size (preferably 0.1 mm to 1 mm) in terms of its short diameter, but is not limited to this size, and may be larger than 2 mm. The material of the foreign body removal forceps 1 is not particularly limited, but examples include metal or synthetic resin. Furthermore, the handle 2, storage section 3, and tip 4 are usually made of the same material and formed integrally, but are not limited to this; they may be manufactured separately or made of different materials.

[0015] Each of the pair of handles 2 is a strip or rod-shaped body, with their end ends 21 joined together. By grasping and loosening the pair of handles 2, the tip ends 24 of the handles 2 can be closed or opened. The joint between the handles 2 may be at the end, or it may be separated from the end towards the tip, as shown in Figure 1, etc.

[0016] The tip portion 23 of the handle portion 2 can be bent relative to other parts such as the end of the handle portion 2. The angle R of the bend of the tip portion 23, as illustrated in Figure 2, can be set to 20 to 34° (preferably 20 to 32°, more preferably 23 to 27°) in the vertical direction of Figure 2, so as illustrated in Figure 9, when removing foreign bodies from the eye such as the cornea, the angle R can be set to 20 to 34° (preferably 20 to 32°, more preferably 23 to 27°) so as not to obstruct the affected area 8 when the foreign body removal forceps 1 is positioned diagonally to the side of the affected area 8.

[0017] The storage section 3, formed at the tip 24 of the handle 2, is a portion for scraping off foreign objects 7 using the opening edge 36, storing foreign objects 7, and / or holding foreign objects 7, and has a hemispherical shape with an opening surface 33 facing the opening surface 33 of the storage section 3 formed at the tip 24 of the other handle 2, or the opposing surface 51 of the opening cover 5. The storage section 3 also includes a viewing window 371. Furthermore, when the pair of handles 2 are grasped and the tip portions 24 of the handles 2 are closed, the opening edges 36 of the opening surfaces 33 of both storage portions 3 come into contact with each other, as illustrated in Figures 13(a) and (b), forming a container structure enclosed by both storage portions 3. At this time, a viewing window 37 is formed by a viewing window portion 371 in a part of the upper portion 31 located above the container structure (upper part of the figure in Figures 6-8 and 12). Furthermore, in the foreign object removal forceps 1, each handle portion 2A and 2B is equipped with a storage portion 3 and an opening lid portion 5, respectively, when the pair of handle portions 2A and 2B are grasped and the tip portions 24A and 24B are closed, as illustrated in Figures 17(a) and (b), when the opening edges 36 of the opening surfaces 33 of both storage portions 3 are brought into contact with each other, a container structure is formed enclosed by the storage portion 3 and the opening lid portion 5. At this time, a viewing window 37, consisting of a viewing window portion 371, is formed in a part of the upper portion 31 located above the container structure (upper part of the figure in Figures 17(a) and (b)).

[0018] The "hemispherical shape" of the storage compartment 3 may be any concave shape with walls on all sides of the bottom or walls, and is not limited to a hemispherical shape obtained by dividing a perfect sphere into two equal parts. It also includes spherical shapes with a radius less than that of a perfect sphere (for example, 4 / 5 of the radius), as well as spherical shapes other than perfect spheres, such as oblong spheres and bottomed spheres. Furthermore, it may also be a shape that includes aspherical parts such as a rectangular parallelepiped with rounded corners. As an example, a long spherical shape can be given, with the axial direction of the handle tip 23 of the handle portion 2 as the major axis. In this case, the opening surface 33 becomes an ellipse with the axial direction of the handle portion 2 as the major axis. The ratio of the minor axis and major axis of the ellipse can be arbitrary. The size of the opening surface 33 of the storage section 3 is preferably large enough to accommodate ordinary foreign objects, and the shorter diameter can be exemplified as 0.2 mm to 2 mm.

[0019] The storage section 3 is provided so as to extend from both sides in the width direction (up and down direction in Figure 6) of the tip of the handle section 2 (handle tip section 23) (see widths S and S' in Figure 6). The widths S and S' of the extending storage section 3 are preferably 0.1 to 1.0 mm. This is because when a foreign object 7 is held in place with the upper end 34 or lower end 35 of the storage section 3 (located perpendicular to the axis of the handle tip section 23) in contact with the affected area 8, a gap of widths S and S' is created between the affected area 8 and the handle section 2, so that the handle section 2 does not come into contact with the affected area 8 and interfere with the procedure. The widths S and S' of the extending storage section 3 may be the same length or may be different lengths.

[0020] The opening edge 36 of the storage section 3 is located on the opening surface 33 of the storage section 3 and can grip or scrape off foreign objects 7. The opening edge 36 preferably has a thickness that makes it easy to scrape off foreign objects 7, and can be, for example, 0.05 mm to 1.0 mm (preferably 0.05 mm to 0.5 mm), which is about half the size of a normal foreign object 7. By making the thickness of the opening edge 36 half the size of the foreign object 7, the foreign object 7 can be made small enough to fit inside the storage section 3 when gripped, scooped up, or scraped off. The thickness of the bottom side of the storage section 3 may be thicker than the thickness of the opening edge 36. It is preferable that the lower end 362 (see Figure 7) of the inner surface side of the storage portion 3 of the opening edge 36 is located below the lower end of the tip of the handle portion 2 (handle tip portion 23). As illustrated in Figure 10, when gripping a foreign object 7 embedded in the affected area 8, it is necessary to temporarily push the storage portion 3 into the affected area 8 to perform the work. At this time, if the lower end 362 is located above the lower end of the tip of the handle portion 2 (handle tip portion 23), the handle portion 2 may come into contact with the affected area 8, which could hinder the movement of the handle portion 2 or cause injury to the affected area 8. In particular, if the affected area 8 is the cornea or the like as illustrated in Figure 10, the affected area will have convex or concave surfaces, so positioning the lower end 362 below the lower end of the tip portion 24 is effective in preventing the handle portion 2 from coming into contact with the affected area 8. The vertical width S'' (see Figure 7) between the lower end 362 and the lower end of the tip of the handle portion 2 (handle end portion 23) can be set as appropriate, for example, to 0.05 mm to 0.5 mm.

[0021] The viewing window 37 of the storage section 3 is an opening provided in the storage section 3 for visually inspecting foreign objects 7 inside the container structure provided by the storage section 3, as illustrated in Figures 12, 13, and 17. The shape of the viewing window can be arbitrarily selected, but in order to observe foreign objects inside the container structure and to prevent foreign objects 7 from falling out of the viewing window 37, an elongated shape with different aspect ratios, such as a rectangle or an ellipse, is preferred. Specifically, it can be a rectangle or an ellipse with the longer axis in the direction along the opening surface 33. Note that the rectangle includes a shape with rounded corners. The size of the viewing window 37 is preferably such that foreign objects 7 do not easily fall out of the viewing window, and it is preferable that the size of the shorter diameter portion be smaller than the size of the foreign object. The structure of the viewing window 37 may be a single opening structure or two or more opening structures. Furthermore, the opening portion may be covered with a light-transmitting resin, glass, or mesh.

[0022] The pointed tip 4 is the part used to excavate, scoop up, or gouge out foreign objects from within the affected area. The pointed tip 4 should have a pointed shape at the end. Furthermore, it is preferable that the tip of the pointed tip 4 is located above the opening. This position, above the other parts of the forceps, prevents the tip used for scooping or gouging from being obscured, making it suitable for use. The length from the end to the tip of the pointed head 4 can be arbitrarily selected and can be 0.5 to 2.5 mm (preferably 1.0 to 1.5 mm), which is about half the size of a normal foreign object and a size that does not easily come into contact with the affected area during operations such as clamping by the storage section 3. The thickness of the edge of the pointed head 4 is preferably the same as the thickness of the opening edge 36 in order to make it easier to insert the pointed head 4 between the foreign object and the affected area. The position of the tip 41 of the pointed head 4 is preferably such that the tip is located above the upper end 34 of the opening surface 33 (upwards in Figure 7), as illustrated in Figure 7. This is suitable because the tip 41, which is used to scoop up or gouge out foreign objects 7, is located above the storage section 3 of the forceps 1, so that the tip 41 is not obstructed by the handle 2 or storage section 3 of the forceps 1, and the use of the pointed head 4 is not hindered. In addition, when storing foreign objects 7 in the storage section 3, the tip 41 of the pointed head 4 does not come into contact with the surface of the affected area 8 and cause injury.

[0023] The opening lid portion 5 is formed at the tip portion 24 of the handle portion 2 and has an opposing surface 51 of a size and shape that can cover the opening surface 33 of the opposing storage portion 3. The opening lid portion 5 may also have a pointed head 4 as illustrated in Figure 14, or it may not have a pointed head 4 as illustrated in Figure 16. In particular, when the opposing storage portion 3 does not have a pointed head 4 and the opening lid portion 5 has a pointed head 4, as illustrated in Figure 14, the work of digging up, scooping up, or gouging out foreign objects 7 can be performed with the pointed head 4 of the handle portion 2B, and the foreign objects 7 can be held in place by the storage portion 3 of the handle portion 2B. This allows for the use of the handle portion 2A and 2B depending on the type of work, and the shape of the storage portion 3 does not hinder the work of the pointed head 4.

[0024] This foreign body removal forceps 1 is primarily used for grasping and removing small foreign bodies attached to the eyeball, etc., but is not limited to this use. It may also be used for grasping and removing foreign bodies attached to the skin, or for grasping and removing foreign bodies inside the external auditory canal, nasal cavity, etc.

[0025] An example of such a foreign body removal forceps will be described. The foreign body removal forceps 1 of the first embodiment is made of metal and comprises a pair of handles 2 joined at their terminal ends 21, as shown in Figures 1-3, and a storage section 3 formed at the tip of the handle end 23 of each handle 2. The handle end 23 is bent at an angle R of approximately 26° relative to the terminal end 21, as shown in Figure 2. As shown in Figures 4-8, the storage section 3 has a hemispherical shape with a visual groove 38 formed on the upper side, and the length in the two directions of the handle is approximately 1.2 mm. Also, as shown in Figures 5 and 8, the opening surfaces 33 of the pair of storage sections 3 are formed facing each other. The thickness of the opening edge 36 of the storage section 3 is approximately 0.3 mm, making it easy to insert or scrape off small foreign objects 7. The axial width S, S' between the upper or lower end of the storage section 3 and the handle section 2 is approximately 0.2 mm. As shown in Figures 6-8, the upper part 31 of the storage section 3 has a visual groove 38 formed above the opening edge 36. As shown in Figure 4, the visual groove 38 curves to form the edge of a visual window 371, which is an opening that allows the bottom surface of the storage section 3 to be seen from above. Also, as shown in Figures 13(a) and 13(b), when the opening surfaces 33 of a pair of storage sections 3 are brought together, the visual window 371s, which are rectangular elongated holes with rounded corners, are combined to form one visual window 37. The visual window 37 is a rectangular elongated hole with rounded corners, and its width is approximately 0.3 mm, making it large enough that many foreign objects 7 larger than approximately 0.3 mm cannot pass through the visual window 37. The storage section 3 is equipped with a pointed tip 4 at its end. The length of the pointed tip 4 from the end to the tip is approximately 1.2 mm. As shown in Figure 7, the tip 41 of the pointed tip 4 is located above the upper end 34 of the opening surface 33.

[0026] When performing the procedure from the patient's head side, the foreign body removal forceps 1 are used from a position oblique to the side relative to the patient, as shown in Figure 9, towards the affected area 8. At this time, the bending causes the handle tip 23 to face laterally relative to the operator, so it does not obstruct the affected area 8. In particular, right-handed operators can easily perform the procedure with their right hand on foreign bodies lodged at the 13:00 to 17:00 side D relative to the corneal center of the right and left eyes. Furthermore, for foreign bodies lodged at the 19:00 to 23:00 side E relative to the corneal center, right-handed operators can easily perform the procedure by switching the foreign body removal forceps 1' to their left hand or reversing its orientation. Even left-handed operators can easily perform the procedure by using their left hand for foreign bodies lodged at the 19:00 to 23:00 side D relative to the corneal center, and their right hand for foreign bodies lodged at the 13:00 to 17:00 side E relative to the corneal center.

[0027] The foreign body removal forceps 1 can be used to scoop up or gouge out the foreign body 7 by inserting its pointed tip 4 between the foreign body 7 and the affected area 8, thereby facilitating the foreign body removal process. If the foreign object 7 is a piece of iron, it will rust within the affected area 8 over time, and the rust will detach from the foreign object 7 and spread throughout the tissue. The pointed tip 4 can grasp and remove the iron foreign object 7 with the storage section 3, and then excavate and remove any rust-like foreign matter remaining within the tissue. This allows for the removal of the iron piece as a foreign object and the removal of the rust caused by the iron piece to be performed continuously without changing the instrument. Furthermore, by making the length of the pointed tip 4 from the end to the tip approximately 1.2 mm, the tip of the pointed tip 4 will not come into contact with the affected area 8 and damage it when the foreign object 7 is grasped or scraped using the opening edge 36 of the storage section 3. In addition, as shown in Figure 7, the tip 41 of the pointed tip 4 is located above the upper end 34 of the opening surface 33, so the tip 41 and the affected area 8 in contact with the tip 41 can be visually inspected and treated without being obstructed by the storage section 3.

[0028] The foreign body removal forceps 1 can remove a foreign body 7 embedded in the affected area 8 shown in Figures 10 and 11 by inserting the opening edge 36 of the storage section 3 between the affected area 8 and the foreign body 7, as shown in Figures 10 and 12, and gripping it in a scooping manner, as shown in Figure 13. At this time, because the thickness of the opening edge 36 of the storage section 3 is sufficiently small compared to the size of the foreign body 7, it is easy to scoop, and even if the foreign body 7 is irregularly shaped, it can be stored in the container structure formed by the storage section 3 without rattling, or gripped by the storage section 3. In addition, the cover section 39 restricts the movement of the foreign body 7 upward from the storage section 3, preventing the foreign body 7 from falling out from above. Furthermore, as shown in Figures 13(a) and (b), the foreign object 7 being held can be visually inspected through the viewing window 37, allowing for immediate confirmation of its condition. Also, as shown in Figure 13(c), even if the storage section 3 cannot make contact with the foreign object 7 due to its size, preventing the formation of a container structure, the edges of the foreign object 7 can be visually inspected through the viewing window 371, allowing for confirmation of a wide area of ​​the foreign object 7. In particular, because the viewing window 37 and the viewing window section 371 are elongated holes, even foreign objects 7 smaller than the length of the elongated hole are less likely to fall out of the viewing window 37 and the viewing window section 371.

[0029] Furthermore, as shown in Figure 6, the storage section 3 is formed so that its upper end 34 and lower end 35 extend from both sides of the tip 24 of the handle 2 by widths S and S', respectively. This creates a gap of widths S and S' between the handle 2 and the surface of the affected area 8. Even when the opening edge 36 is inserted between the affected area 8 and the foreign object 7, the foreign object 7 does not come into contact with the handle 2 and rattle, preventing it from rattling and falling after being gripped. In addition, the foreign object 7 that was exposed from the affected area 8 can be contained within the storage section 3, preventing it from falling out. Furthermore, as shown in Figure 7, the lower end 362 on the inner surface side of the opening edge 36 of the storage section 3 is located below the lower end of the tip 24 of the handle 2 by a width S'', making it difficult for the handle 2 to come into contact with the affected area 8. This prevents the movement of the handle 2 from being obstructed and prevents the handle 2 from injuring the affected area 8.

[0030] The present invention is not limited to the embodiments detailed above, and various modifications or changes are possible within the scope of the claims of the present invention. In other words, although the foreign body removal forceps 1 of the embodiment had a pointed tip 4 on both storage sections 3, it is not limited to this, and the pointed tip 4 may be provided on only one of the storage sections 3, or neither storage section 3 may have a pointed tip 4. Also, as shown in Figures 14 to 16, a storage section 3 can be formed on the tip 24A of one handle section 2A, and an opening lid section 5 can be formed on the tip 24B of the other handle section 2B. Such a foreign body removal forceps 1 can contain a foreign object 7 in the storage section 3, as shown in Figure 17, similar to a foreign body removal forceps 1 with two storage sections 3. Furthermore, as shown in Figures 17(a) and 17(b), the foreign object 7 can be seen through the viewing window 37 even when the opening surface 33 of the storage section 3 is covered by the opening lid section 5. Also, as shown in Figure 17(c), the foreign object 7 can be seen through the viewing window 371 even when the foreign object 7 is being held between the storage section 3 and the opening lid section 5. Furthermore, even if an opening lid portion 5 is formed at the tip portion 24A of the handle portion 2A and a storage portion 3 is formed at the tip portion 24B of the other handle portion 2B, the same effect as the foreign body removal forceps 1 shown in Figures 14 to 16 can be obtained.
