Description

Technical Field

[0001] The present invention belongs to the technical field of surgical instruments, and specifically relates to a device for removing fishhooks from a human body, and more particularly to a foreign body removal device for a human body and a method of using the device. Background Art

[0002] There are many ways to remove fish hooks by human body. The following methods are used in related technologies to remove fish hooks:

[0003] In the first, you wrap a long strand of line around the bend of the hook, apply downward pressure to break the barb and push it back into place, then give a quick, hard tug on the line to remove the hook.

[0004] Second, insert an 18G needle into the barbed side of the hook with the tip facing inside the hook curve, then gently push the needle down until its hole covers the barb. Slightly rotate the barb downward so that the hook curve is facing up, then remove the needle and hook together through the original wound.

[0005] The third type is that the fishhook penetrates deeply into the skin. You should first anesthetize the surrounding skin, then use tweezers to push the fishhook away from the skin, cut off the eye of the fishhook where the fishing line is fixed, and then pull it out in the direction where the fishhook penetrates the skin.

[0006] The first two methods are only applicable when the fishhook penetrates the skin shallowly, with only the tip inserted. When the fishhook penetrates deeply, the first method will cause a large amount of human tissue to accumulate at the barb, making it impossible to pull it out. The human tissue at the barb needs to be removed several times before it can be pulled out, which will cause the wound to expand. In the second method, since the needle is straight, once the bend of the fishhook penetrates the skin, the barb cannot be covered by the needle hole.

[0007] Although the third method can solve the problem of the fish hook piercing deeply into the skin, it requires the fish hook to pierce the skin to form a penetration, and then pull the fish hook out. This method requires a high insertion angle and will cause the wound to become deeper and longer.

[0008] Therefore, how to remove fish hooks that have penetrated deeply into the skin while reducing secondary damage to the skin is a technical problem that needs to be solved urgently.

[0009] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art. Summary of the invention

[0010] The embodiments of the present disclosure at least provide a foreign body removal device for human body and a method for using the same.

[0011] In a first aspect, an embodiment of the present disclosure provides a foreign body removal device for human body, comprising:

[0012] A hose and a plurality of snap-fit ​​assemblies;

[0013] The buckle assembly is provided with a plug hole;

[0014] The plurality of buckling components are connected along a straight line, and two adjacent buckling components are connected in a rotational manner;

[0015] The hoses are sequentially inserted into the insertion holes of the snap-fit ​​components;

[0016] A covering block is provided at the end of the hose;

[0017] Among them, after the multiple snap-fit ​​components are fitted to the side walls of the fish hook and inserted from the handle into the skin in sequence, the hoses are inserted into the sockets of the snap-fit ​​components in sequence until the covering block covers the barbs of the fish hook.

[0018] In an optional embodiment, the side wall of the hose is further provided with a guide strip;

[0019] The buckle assembly is provided with a first slot and a second slot communicating with the socket.

[0020] The first slot is arranged opposite to the second slot, and the first slot is arranged close to the side wall of the fish hook;

[0021] In the initial state, the guide strip of the hose is inserted into the first slot;

[0022] When removing the fishhook, when pulling the hose out of the snap-fit ​​assembly, the corresponding snap-fit ​​assembly engages with the side wall of the fishhook until the snap-fit ​​assembly abuts against the barb of the fishhook, the hose is completely pulled out, and the hose is inserted into the insertion hole of the snap-fit ​​assembly in sequence through the guidance of the guide strip and the second slot until the covering block covers the barb of the fishhook.

[0023] In an optional embodiment, the buckle assembly includes: a hinge block, a first arc-shaped buckle plate, and a second arc-shaped buckle plate;

[0024] The jack is provided on the hinge block;

[0027] The first arc-shaped buckling plate and the second arc-shaped buckling plate are provided with elastic triggering parts facing the first slot;

[0028] When the guide bar is inserted into the first slot, the guide bar abuts against the elastic triggering parts of the first arc-shaped buckling plate and the second arc-shaped buckling plate respectively, and opens the first arc-shaped buckling plate and the second arc-shaped buckling plate outward;

[0029] When the guide strip is pulled out of the first slot, the first arc-shaped buckling plate and the second arc-shaped buckling plate are closed inwardly under the action of the elastic triggering portion.

[0030] In an optional embodiment, the elastic triggering portion includes: a holding plate and a spring;

[0031] The first arc-shaped buckling plate and the second arc-shaped buckling plate are connected to the corresponding abutting plate;

[0032] One end of the spring sheet is arranged at the bottom of the rotating groove, and the other end is abutted against the bottom surface of the abutting plate;

[0033] When the guide bar is inserted into the first slot, the guide bar presses the abutting plate, causing the spring sheet to undergo elastic deformation, and the first arc-shaped buckling plate and the second arc-shaped buckling plate to open outwards;

[0034] When the guide bar is pulled out of the first slot, the spring sheet recovers its deformation and pushes the supporting plate upward, thereby closing the first arc-shaped buckling plate and the second arc-shaped buckling plate inward.

[0035] In an optional embodiment, the curvature of the first arc-shaped snap-fitting plate is adapted to the side wall of the fishhook.

[0036] In an optional embodiment, two adjacent hinge blocks are respectively provided with a rotating part and a rotating shaft;

[0037] Two adjacent hinge blocks are rotatably connected via a rotating portion and the rotating shaft.

[0038] In an optional embodiment, the opposing surfaces of two adjacent hinge blocks are both inclined surfaces.

[0039] In an optional embodiment, the cover block and the guide strip are integrally formed, and the size of the cover block matches the size of the guide strip;

[0040] The top surface of the covering block is an inclined surface.

[0041] In an optional embodiment, after the covering block covers the barb of the fishhook, the hose is further adapted to inject physiological saline into the skin, thereby expanding the tissue near the barb outward.

[0042] In a second aspect, the present disclosure also provides a method for using the above-mentioned foreign body removal device for human body, the method comprising:

[0043] The buckle assembly is sequentially attached to the side wall of the fish hook and inserted from the handle into the skin until the buckle assembly abuts against the barb of the fish hook;

[0044] Insert the hose into the socket until the cover piece of the hose covers the barb of the fish hook;

[0045] Inject saline solution into the skin through a hose to expand the tissue near the barb outward;

[0046] The fish hook and the human body are slowly pulled out at the same time using the foreign body removal device to complete the removal of the fish hook.

[0047] The beneficial effect of the present invention is that the human body foreign body removal device and the use method thereof are fitted on the side wall of the fish hook through multiple snap-fit ​​components that are connected and rotated in sequence, and can be rotated according to the curvature of the fish hook, and then the hose is inserted into the reserved socket, so that the hose covers the barbs of the fish hook to meet the removal needs of fish hooks of different depths. At the same time, because the snap-fit ​​component fits the side wall of the fish hook and the fish hook is pulled out in the direction of the fish hook being inserted, the secondary damage to the skin is reduced, and the complexity of removing the fish hook is greatly reduced.

[0048] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

[0060] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] See also Figure 1At least one embodiment provides a foreign body removal device for human body, comprising: a hose 100 and a plurality of snap-fit ​​components 200; the snap-fit ​​components 200 are provided with a plug hole 210; a plurality of the snap-fit ​​components 200 are connected along a straight line, and two adjacent snap-fit ​​components 200 are rotatably connected; the hose 100 is inserted into the plug hole 210 of the snap-fit ​​components 200 in sequence, and a covering block 110 is provided at the end of the hose 100; wherein, after the plurality of the snap-fit ​​components 200 are fitted against the side wall of the fish hook 300 and inserted from the handle and pushed into the skin in sequence, the hose is inserted into the plug hole of the snap-fit ​​component in sequence until the covering block 110 covers the barb 310 of the fish hook 300. Through multiple snap-fit ​​components 200 connected by rotating in sequence, they are attached to the side wall of the fish hook 300 and can be rotated according to the curvature of the fish hook 300. Then the hose 100 is inserted into the reserved socket 210, so that the hose 100 covers the barb 310 of the fish hook 300 to meet the removal requirements of fish hooks 300 of different depths. At the same time, since the snap-fit ​​component 200 is attached to the side wall of the fish hook 300 and the fish hook 300 is pulled out according to the direction in which the fish hook 300 is inserted, the secondary damage to the skin is reduced and the complexity of removing the fish hook 300 is greatly reduced.

[0062] See also Figure 1-Figure 4 In some embodiments, the side wall of the hose 100 is further provided with a guide strip 120; the buckle assembly 200 is provided with a first slot 220 and a second slot 230 connected to the plug hole 210. The first slot 220 and the second slot 230 are arranged opposite to each other, and the first slot 220 is arranged close to the side wall of the fish hook 300; in the initial state, the guide strip 120 of the hose 100 is inserted into the first slot 220, such as Figure 2 As shown; when removing the fishhook 300, when the hose 100 is pulled out of the buckle assembly 200, the corresponding buckle assembly 200 is engaged with the side wall of the fishhook 300 until the buckle assembly 200 and the barb 310 of the fishhook 300 are abutted, the hose 100 is completely pulled out, and the hose 100 is inserted into the insertion hole 210 of the buckle assembly 200 in sequence through the guidance of the guide strip 120 and the second slot 230, as shown in FIG. Figure 3 As shown, until the cover block 110 covers the barb 310 of the fish hook 300. The guide strip 120 is provided to open the fastening assembly 200. When the fastening assembly 200 needs to be fastened with the side wall of the fish hook 300, the guide strip 120 is pulled out while the hose 100 is pulled out, so that the fastening assembly 200 is fastened on the fish hook 300, so that the insertion hole 210 is aligned with the barb 310, and the subsequent covering block 110 covers the barb 310.

[0063] See also Figure 5In some embodiments, the buckle assembly 200 includes: a hinge block 240, a first arc buckle plate 250, and a second arc buckle plate 260; the jack 210 is provided on the hinge block 240; the hinge block 240 is provided with a rotation groove 241 connected to the first slot 220; the first arc buckle plate 250 and the second arc buckle plate 260 are respectively arranged on both sides of the first slot 220, and are rotatably arranged in the rotation groove 241 of the hinge block 240; the first arc buckle plate 250 and the second arc buckle plate 260 are respectively arranged on both sides of the first slot 220, and are rotatably arranged in the rotation groove 241 of the hinge block 240; 60 An elastic trigger portion 270 is provided toward the first slot 220; when the guide bar 120 is inserted into the first slot 220, the guide bar 120 abuts against the elastic trigger portions 270 of the first arc-shaped snap-fit ​​plate 250 and the second arc-shaped snap-fit ​​plate 260 respectively, and opens the first arc-shaped snap-fit ​​plate 250 and the second arc-shaped snap-fit ​​plate 260 outward; when the guide bar 120 is pulled out of the first slot 220, the first arc-shaped snap-fit ​​plate 250 and the second arc-shaped snap-fit ​​plate 260 are closed inwardly under the action of the elastic trigger portion 270.

[0064] The structure of the elastic triggering part 270 is described below. In a preferred embodiment, the elastic triggering part 270 includes: a supporting plate 271 and a spring 272; the first arc-shaped snap-fitting plate 250 and the second arc-shaped snap-fitting plate 260 are connected to the corresponding supporting plate 271; one end of the spring 272 is arranged at the bottom of the rotating groove 241, and the other end is pressed against the bottom surface of the supporting plate 271; when the guide bar 120 is inserted into the first slot 220, the guide bar 120 squeezes the supporting plate 271, so that the spring 272 is elastically deformed, and the first arc-shaped snap-fitting plate 250 and the second arc-shaped snap-fitting plate 260 are opened outwardly; when the guide bar 120 is pulled out of the first slot 220, the spring 272 restores its deformation and pushes the supporting plate 271 upward, thereby closing the first arc-shaped snap-fitting plate 250 and the second arc-shaped snap-fitting plate 260 inwardly.

[0065] It should be noted that the curvature of the first curved buckle plate 250 is adapted to the side wall of the fish hook 300. For fish hooks 300 of different diameters, the first curved buckle plate 250 and the second curved buckle plate 260 with corresponding curvatures are produced, so that the first curved buckle plate 250 and the second curved buckle plate 260 tightly wrap the fish hook 300, thereby ensuring that the buckle assembly 200 will not deviate when inserted into the skin.

[0066] Please continue reading Figure 1 The two adjacent hinge blocks 240 are respectively provided with a rotating part 280 and a rotating shaft 290 ; the two adjacent hinge blocks 240 are rotatably connected through the rotating part 280 and the rotating shaft 290 .

[0067] In order to ensure that the hinge blocks 240 do not cause interference when rotating, in a preferred embodiment, the opposing surfaces of two adjacent hinge blocks 240 are both inclined surfaces.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the cover block 110 and the guide bar 120 are integrally formed, and the size of the cover block 110 matches the size of the guide bar; the top surface of the cover block 110 is an inclined surface. In order to improve the overall strength of the cover block 110, the cover block 110 and the guide bar 120 are integrally formed, and at the same time, the size of the cover block 110 matches the size of the guide bar, which facilitates the insertion of the hose 100. Since there is a gap between the insertion holes 210 of adjacent hinge blocks 240, after the hinge block 240 rotates, the cover block 110 with the inclined top surface is used for guidance, which facilitates the insertion of the hose 100.

[0069] After the cover block 110 covers the barbs 310 of the fishhook 300, the hose 100 is further adapted to inject physiological saline into the skin, thereby expanding the tissue near the barbs 310 outward, thereby facilitating the removal of the fishhook 300. At the same time, due to the presence of the first slot 220, the space in the insertion tube can be depressurized, facilitating the exhaust of air from the hose 100.

[0070] See also Figure 6 At least one embodiment also provides a method for using the above-mentioned foreign body removal device for human body, which method includes: sequentially fitting the snap-fit ​​assembly 200 to the side wall of the fish hook 300 and inserting it from the handle into the skin, until the snap-fit ​​assembly 200 abuts against the barb 310 of the fish hook 300; inserting the hose 100 into the insertion hole 210 until the cover block 110 of the hose 100 covers the barb 310 of the fish hook 300; injecting physiological saline into the skin through the hose 100 to expand the tissue near the barb 310 outward; slowly pulling out the fish hook 300 and the foreign body removal device for human body at the same time to complete the removal of the fish hook 300. It should be noted that before using the foreign body removal device for human body, the skin around the fish hook 300 needs to be locally anesthetized.

[0071] In summary, the present invention provides a foreign body removal device for human body and a method of using the same, wherein the foreign body removal device for human body comprises: a hose 100 and a plurality of snap-fit ​​components 200; the snap-fit ​​components 200 are provided with a socket 210; a plurality of the snap-fit ​​components 200 are connected along a straight line, and two adjacent snap-fit ​​components 200 are rotatably connected; the hose 100 is inserted into the socket 210 of the snap-fit ​​components 200 in turn; a covering block 110 is provided at the end of the hose 100; wherein, after the plurality of the snap-fit ​​components 200 are fitted against the side wall of the fish hook 300 and inserted from the handle and pushed into the skin in turn, the hose 100 is inserted into the socket 210 of the snap-fit ​​components 200 in turn until the covering block 110 covers the barb 310 of the fish hook 300. Through multiple snap-fit ​​components 200 connected by rotating in sequence, they are attached to the side wall of the fish hook 300 and can be rotated according to the curvature of the fish hook 300. Then the hose 100 is inserted into the reserved socket 210, so that the hose 100 covers the barb 310 of the fish hook 300 to meet the removal requirements of fish hooks 300 of different depths. At the same time, since the snap-fit ​​component 200 is attached to the side wall of the fish hook 300 and the fish hook 300 is pulled out according to the direction in which the fish hook 300 is inserted, the secondary damage to the skin is reduced and the complexity of removing the fish hook 300 is greatly reduced.
