Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically relating to a multifunctional forceps. Background Technology
[0002] Medical forceps are tools used to pick up small objects. They are simple in structure and easy to operate, and are frequently used in otolaryngology and dentistry. However, existing forceps have limited functionality. During oral examinations, doctors or nurses need to hold the forceps in one hand and a tongue depressor in the other. Furthermore, the forceps or tongue depressor must be put down to adjust the lighting, which is inconvenient, affects the oral examination process, prolongs the examination time, and hinders the improvement of oral examination efficiency.
[0003] Currently, there are precedents for combining tweezers with tongue depressors. For example, Chinese utility model patent application number CN201821167272.0 discloses a medical nursing tweezer, in which a first tweezer leg 2 and a second tweezer leg 3 are fixedly installed on one side of the outer surface of the tweezer head 1, and a tongue depressor plate 8 is fixedly installed on the other side of the outer surface of the tweezer head 1. Thus, the medical nursing tweezer can be used to both pick up items and depress the tongue. However, the above-mentioned medical nursing tweezer requires reversing its direction to use the tongue depressor plate 8, and cannot achieve the tongue depressor function at the item picking end, still presenting a certain degree of inconvenience in use. Summary of the Invention
[0004] The present invention aims to provide a multifunctional forceps to solve the problem of inconvenience caused by the fact that the gripping function and the tongue depressor function are located at opposite ends of medical forceps.
[0005] To achieve the above objectives, the present invention provides a multifunctional tweezers comprising a tongue depressor, a tweezer handle, and two tweezer arms. One end of each tweezer arm is connected to the handle, and the other end of each arm is provided with a tweezer tip. One tweezer arm is rotatably connected to a transverse pin, and the end of the transverse pin located between the two tweezer arms is provided with a locking element. The other tweezer arm has a through groove for the locking element to pass through. An arc-shaped connector is fixedly connected to the end of the transverse pin away from the locking element. A vertical connecting post is provided at the end of the arc-shaped connector away from the transverse pin. An I-shaped slider is rotatably connected to the end of the vertical connecting post away from the arc-shaped connector. A T-shaped groove is provided on the tongue depressor that slides with the I-shaped slider. The T-shaped groove is arranged along the length of the tongue depressor.
[0006] The working principle and beneficial effects of this solution are as follows: In this solution, the forceps arm can rotate circumferentially along the horizontal pin (first dimension), and the forceps arm can rotate circumferentially along the vertical connecting post (second dimension). The forceps arm can also move relative to the tongue depressor along the length of the tongue depressor (third dimension). Thus, in this solution, the forceps arm can move in three dimensions, allowing the gripping and tongue depressing functions to be located at the same end of the medical forceps. Furthermore, this multifunctional forceps offers multiple working modes: tongue depressing mode, object retrieval mode, and tongue depressing and object retrieval mode. This allows doctors or nurses to select the appropriate mode based on the actual situation, avoiding the need for doctors or nurses to reverse the forceps before performing tongue depressing or object retrieval, making operation convenient and improving the efficiency of oral examinations.
[0007] Optionally, the locking element is threaded to one end of the transverse pin located between the two tweezer arms.
[0008] In this solution, the locking component can be removed from the transverse pin, thereby separating the transverse pin from the tweezers arm, and further separating the tongue depressor from the tweezers arm, facilitating replacement and cleaning / disinfection.
[0009] Optionally, the arc-shaped connector is an arc-shaped metal spring.
[0010] In this solution, when the curved connector uses a curved metal spring, the curved metal spring is elastic. Thus, when a doctor or nurse applies pressure to the forceps arm, the curved metal spring deforms, and the distance between the forceps arm and the tongue depressor changes, making it easier to use.
[0011] Optionally, the arc-shaped metal spring is provided with a rubber ring, which is located on the outer periphery of the transverse pin.
[0012] In this design, the rubber ring increases the frictional resistance encountered when the transverse pin rotates, thus making it easier for doctors or nurses to control the rotation of the forceps arm.
[0013] Optionally, the arc-shaped connector has a through hole at the end away from the transverse pin for the vertical connecting post to pass through, and a baffle is provided at the end of the vertical connecting post near the I-shaped slider. An elastic element is provided between the end of the arc-shaped connector away from the transverse pin and the baffle. One end of the elastic element is fixedly connected to the arc-shaped connector, and the other end of the elastic element is fixedly connected to the baffle.
[0014] In this design, the vertical connecting post can penetrate the through hole in the arc-shaped connector. Utilizing the elastic element between the arc-shaped connector and the baffle, the arc-shaped connector can move axially relative to the vertical connecting post, thereby enabling the arc-shaped connector and the tweezers arm to move vertically relative to the tongue depressor. Thus, even after the tongue depressor presses down on the tongue, the tweezers arm can still move axially along the vertical connecting post, making it easier for the tweezers to pick up objects.
[0015] Optionally, the baffle plate and the vertical connecting column are integrally formed.
[0016] In this design, the baffle and the vertical connecting column are integrally formed, which provides better overall integrity compared to welding the baffle and the vertical connecting column.
[0017] Optionally, the I-shaped slider has mounting holes, including a first circular hole and a second circular hole. The end of the vertical connecting post away from the arc-shaped connecting member is provided with a limiting post. The diameter of the limiting post is larger than the diameter of the vertical connecting post. The limiting post is adapted to the diameter of the second circular hole, and the vertical connecting post is adapted to the diameter of the first circular hole.
[0018] In this design, the limiting post is located inside the second circular hole, and the diameter of the second circular hole is larger than that of the first circular hole, thereby realizing the rotational connection between the vertical connecting post and the I-shaped slider.
[0019] Optionally, the tongue depressor has a boss on the side facing the tweezers arm, and the T-shaped groove is provided on the boss.
[0020] In this design, the boss provides a location for the T-shaped groove, thus avoiding excessive thickness of the tongue depressor plate.
[0021] Optionally, the outer wall surface of the tweezers arm is provided with anti-slip grooves.
[0022] In this design, the anti-slip grooves on the tweezers arms prevent slippage, allowing users to hold the tweezers arms more stably.
[0023] Optionally, the locking member is provided with an annular ear plate, which can be attached to the side wall surface of the tweezer arm.
[0024] In this design, when the locking component locks the transverse pin at one end between the two tweezer arms, the annular ear plate is in contact with the side wall of the tweezer arm, thereby increasing the contact area between the locking component and the tweezer arm and improving the stability of the locking component locking the transverse pin.

[0031] The markings in the accompanying drawings of the instruction manual include: tongue depressor 1, tweezer handle 2, tweezer arm 3, anti-slip groove 301, tweezer tip 4, transverse pin 5, locking element 6, annular ear plate 7, through groove 8, arc-shaped metal spring 9, vertical connecting post 10, rubber ring 11, I-shaped slider 12, limiting post 13, boss 14, T-shaped slide 141, baffle 15, elastic element 16.
[0032] Example 1
[0033] This embodiment is basically as follows: Figure 1 , Figure 2 and Figure 3 As shown: A multifunctional tweezers includes a tongue depressor 1, a handle 2, and two tweezer arms 3. One end of each tweezer arm 3 is integrally formed with the handle 2, and the other end of each tweezer arm 3 is integrally formed with a tweezer tip 4. Anti-slip grooves 301 are provided on the outer wall surface of each tweezer arm 3. Combined with... Figure 4 As shown, one of the two tweezer arms 3 is rotatably connected to a transverse pin 5. Specifically, the tweezer arm 3 has a transverse pin hole, through which the transverse pin 5 passes. A locking member 6 is provided at the inner end of the transverse pin 5 (the inner end of the transverse pin 5 refers to the end of the transverse pin 5 located between the two tweezer arms 3). In this embodiment, the locking member 6 is threaded to the inner end of the transverse pin 5 so that the locking member 6 can be removed from the transverse pin 5. An annular ear plate 7 is integrally formed on the locking member 6, and the annular ear plate 7 is in contact with the side wall of the tweezer arm 3 when the locking member 6 locks the transverse pin 5. A through groove 8 is provided on the other tweezer arm 3 for the locking member 6 to pass through. An arc-shaped connector is fixedly connected to the outer end of the transverse pin 5 (the outer end of the transverse pin 5 refers to the end of the transverse pin 5 away from the locking member 6). The bottom end of the arc-shaped connector is provided with a vertical connecting post 10. In this embodiment, the arc-shaped connector is an arc-shaped metal spring 9. The top end of the vertical connecting post 10 is welded to the bottom end of the arc-shaped metal spring 9. In addition, a rubber ring 11 is bonded to the arc-shaped metal spring 9. The rubber ring 11 is located on the outer periphery of the transverse pin 5. When the locking member 6 locks the transverse spool, the rubber ring 11 is in close contact with the side wall surface of the tweezer arm 3.
[0034] The bottom end of the vertical connecting column 10 is rotatably connected to an I-shaped slider 12. Specifically, the bottom end of the vertical connecting column 10 is integrally formed with a limiting column 13, the diameter of which is larger than the diameter of the vertical connecting column 10. The I-shaped slider 12 has mounting holes, including a first circular hole and a second circular hole. The diameter of the limiting column 13 is matched with the diameter of the second circular hole, and the diameter of the vertical connecting column 10 is matched with the diameter of the first circular hole. The tongue depressor 1 is integrally formed with a boss 14, and the boss 14 has a T-shaped groove 141 that slides with the I-shaped slider 12. The T-shaped groove 141 is arranged along the length direction of the tongue depressor 1.
[0035] In use, the user (doctor or nurse) holds the forceps arm 3 and places the forceps tip 4 and tongue depressor 1 into the patient's mouth. When a foreign object needs to be removed, the user squeezes the two forceps arms 3 together, bringing them closer together, which in turn brings the two forceps tips 4 closer together, thus allowing the foreign object to be removed. During this process, the transverse pin 5 will not rotate relative to the forceps arm 3 due to frictional resistance when it rotates relative to the forceps arm 3 without external force. Therefore, when the forceps tip 4 removes the foreign object, the curved metal spring 9 and the tongue depressor 1 will not affect the removal process.
[0036] When tongue depressor is needed, the user holds the tweezers arm 3 and places the tongue depressor 1 on the patient's tongue. Then, the user presses down on the tweezers arm 3, and applies pressure to the tongue depressor 1 through the horizontal pin 5, the arc-shaped metal spring 9, the vertical connecting column 10 and the I-shaped slider 12, so that the tongue depressor 1 presses down on the patient's tongue.
[0037] Additionally, when it is necessary to grasp a foreign object while depressing the tongue, after depressing the tongue, the user pulls the tweezer arm 3, causing the I-shaped slider 12 to slide along the length of the tongue depressor 1. This allows the tweezer arm 3 to move along the length of the tongue depressor 1, and a force is applied to the tweezer arm 3, causing it to rotate circumferentially on the transverse pin 5 and circumferentially on the vertical connecting post 10. Furthermore, after the tweezer arm 3 is subjected to force, the arc-shaped metal spring 9 deforms, adjusting the position of the tweezers tip 4, thereby enabling the tweezers tip 4 to successfully grasp the foreign object. During this process, the tongue depressor 1 presses down on the patient's tongue and does not move. Alternatively, if the above operation fails to bring the tweezers tip 4 close to the foreign object, the position of the tongue depressor 1 can be moved, and the patient's tongue can be depressed again near the foreign object.
[0038] In summary, in this embodiment, the object-grabbing and tongue-depressing functions of the multifunctional tweezers are located at the same end of the tweezers. Furthermore, the tweezer arm 3 can rotate circumferentially around the transverse pin 5, rotate circumferentially around the vertical connecting post 10, and move relative to the tongue depressor 1 along its length. In addition, the curved metal spring 9 can deform, allowing the tweezer arm 3 to move within its deformation range. Therefore, the multifunctional tweezers in this embodiment are easy to use, allowing selection of three working modes: tongue depressing, object-grabbing, and tongue-depressing-object-grabbing, thus improving the efficiency of oral examinations. Furthermore, in this embodiment, after removing the locking member 6, the tongue depressor 1 can be separated from the tweezer arm 3, facilitating cleaning and disinfection, and also making it easy to replace the tongue depressor 1 or the tweezer arm 3.
[0039] Example 2
[0040] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, in this embodiment, the bottom end of the arc-shaped metal spring 9 has a through hole for the vertical connecting post 10 to pass through. A baffle 15 is integrally formed at the bottom end of the vertical connecting post 10. An elastic element 16 is provided between the bottom end of the arc-shaped metal spring 9 and the baffle 15. The top end of the elastic element 16 is welded to the arc-shaped metal spring 9, and the bottom end of the elastic element 16 is welded to the baffle 15. In this embodiment, the elastic element 16 is a spring.
[0041] In this embodiment, when the user applies force to the tweezers arm 3 so that the tweezers arm 3 is close to the tongue depressor 1, in addition to the deformation of the arc-shaped metal spring 9 to provide space for the tweezers arm 3 to move closer to the tongue depressor 1, the arc-shaped metal spring 9 overcomes the elastic force of the elastic element 16 and moves downward as a whole, so that the tweezers arm 3 is closer to the tongue depressor 1, thereby increasing the range of motion of the tweezers mouth 4 so that the tweezers mouth 4 can better grasp foreign objects.
