Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a pair of multifunctional tweezers. Background Art

[0002] Medical tweezers are a tool that can pick up small objects. They have a simple structure and are easy to operate. They are often used in otolaryngology and stomatology. Existing tweezers have a single function. When performing an oral examination, doctors or nurses need to hold the tweezers in one hand and the tongue depressor in the other hand. In addition, they need to put down the tweezers or the tongue depressor to adjust the light, which is inconvenient to use, affects the oral examination process, prolongs the oral examination time, and is not conducive to improving the efficiency of oral examinations.

[0003] At present, there are precedents for combining tweezers with tongue depressors. For example, the Chinese utility model patent with application number CN201821167272.0 discloses a medical care tweezers, in which a No. 1 tweezer leg 2 and a No. 2 tweezer leg 3 are fixedly installed on the outer surface of one side of the tweezers head 1, and a tongue depressor 8 is fixedly installed on the outer surface of the other side of the tweezers head 1. In this way, the medical care tweezers can be used to clamp objects and to press down the tongue. However, the above-mentioned medical care tweezers need to be turned around before the tongue depressor 8 can be used, and the tongue depressing function cannot be realized at the clamping end, and there is still a certain degree of inconvenience in use. Summary of the invention

[0004] The present invention aims to provide a multifunctional tweezers to solve the problem that the clamping function and the tongue pressing function are respectively located at two ends of the medical tweezers, which is inconvenient to use.

[0005] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a multifunctional tweezers, comprising a tongue depressor, a tweezer handle and two tweezer arms, one end of the tweezer arm is connected to the tweezer handle, and the other end of the tweezer arm is provided with a tweezer mouth, one of the tweezer arms is rotatably connected with a transverse pin, and the end of the transverse pin located between the two tweezer arms is provided with a locking piece, and the other tweezer arm is provided with a through groove for the locking piece to pass through; the end of the transverse pin away from the locking piece is fixedly connected with an arc-shaped connecting piece, the end of the arc-shaped connecting piece away from the transverse pin is provided with a vertical connecting column, the end of the vertical connecting column away from the arc-shaped connecting piece is rotatably connected with an I-shaped slider, the tongue depressor is provided with a T-shaped groove that slidably cooperates with the I-shaped slider, and the T-shaped groove is arranged along the length direction 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 in the circumferential direction of the horizontal pin shaft (first dimension), and the forceps arm can rotate in the circumferential direction of the vertical connecting column (second dimension), and the forceps arm can move relative to the tongue depressor in the length direction of the tongue depressor (third dimension). In this way, in this solution, the forceps arm can move in three dimensions, so that the clamping function and the tongue pressing function are located at the same end of the medical forceps. In addition, the multifunctional forceps in this solution have various working modes: tongue pressing mode, object picking mode and tongue pressing and object picking mode. In this way, doctors or nurses can choose the working mode according to actual conditions, avoiding doctors or nurses turning the direction of the forceps to press the tongue or pick up objects, which is convenient to operate and improves the efficiency of oral examination.

[0007] Optionally, the locking member is threadedly connected to one end of the transverse pin located between the two forceps arms.

[0008] In this solution, the locking piece can be removed from the transverse pin shaft, thereby separating the transverse pin shaft from the forceps arm, and further separating the tongue depressor from the forceps arm, which is convenient for replacement and cleaning and disinfection.

[0009] Optionally, the arc-shaped connecting member is an arc-shaped metal spring.

[0010] In this solution, when the arc-shaped connecting member adopts an arc-shaped metal spring sheet, the arc-shaped metal spring sheet is elastic. In this way, when the doctor or nurse applies pressure to the forceps arm during use, the arc-shaped metal spring sheet is deformed, and the distance between the forceps arm and the tongue depressor changes, making it easier to use.

[0011] Optionally, a rubber ring is provided on the arc-shaped metal spring sheet, and the rubber ring is located on the outer periphery of the transverse pin shaft.

[0012] In this solution, the rubber ring piece can increase the friction resistance encountered by the lateral pin shaft when it rotates, thereby making it easier for doctors or nurses to control the rotation of the forceps arm.

[0013] Optionally, a through hole for a vertical connecting column to pass through is provided at one end of the arc-shaped connecting member away from the transverse pin shaft, a baffle is provided at one end of the vertical connecting column close to the I-shaped slider, an elastic member is provided between the end of the arc-shaped connecting member away from the transverse pin shaft and the baffle, one end of the elastic member is fixedly connected to the arc-shaped connecting member, and the other end of the elastic member is fixedly connected to the baffle.

[0014] In this solution, the vertical connecting column can pass through the through hole on the arc-shaped connecting piece, and the elastic member between the arc-shaped connecting piece and the blocking piece is used to realize the axial movement of the arc-shaped connecting piece relative to the vertical connecting column, thereby realizing the vertical movement of the arc-shaped connecting piece and the forceps arm relative to the tongue depressor. In this way, after the tongue is pressed down by the tongue depressor, the forceps arm can still move in the axial direction of the vertical connecting column, which is more conducive to the tweezers mouth to pick up objects.

[0015] Optionally, the blocking piece is integrally formed with the vertical connecting column.

[0016] In this solution, the baffle and the vertical connecting column are integrally formed, and compared with the method of welding the baffle and the vertical connecting column, the former has better integrity.

[0017] Optionally, the I-shaped slider is provided with a mounting hole, the mounting hole includes a first circular hole and a second circular hole, and a limiting column is provided at one end of the vertical connecting column away from the arc-shaped connecting piece, the diameter of the limiting column is larger than the diameter of the vertical connecting column, the limiting column is adapted to the aperture of the second circular hole, and the vertical connecting column is adapted to the aperture of the first circular hole.

[0018] In this solution, the limiting column is located in 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 column and the I-shaped slider.

[0019] Optionally, a boss portion is provided on a side surface of the tongue depressor facing the forceps arm, and the T-shaped slide groove is provided on the boss portion.

[0020] In this solution, the boss portion provides a position for the slotting of the T-shaped slide groove, thereby preventing the overall thickness of the tongue depressor from being too thick.

[0021] Optionally, an anti-slip groove is provided on the outer wall surface of the forceps arm.

[0022] In this solution, the anti-skid groove on the tweezer arm can prevent slipping, so that the user can hold the tweezer arm more stably.

[0023] Optionally, the locking member is provided with an annular ear plate, which can be in contact with the side wall surface of the forceps arm.

[0024] In this solution, when the locking member locks the transverse pin at one end between the two tweezer arms, the annular ear plate is in contact with the side wall surface of the tweezer arm, thereby increasing the contact area between the locking member and the tweezer arm and improving the stability of the locking member locking the transverse pin.

[0032] Embodiment 1

[0033] This embodiment is basically Figure 1 , Figure 2 and Figure 3 As shown: a multifunctional tweezers, including a tongue depressor 1, a tweezer handle 2 and two tweezer arms 3, one end of the tweezer arm 3 is integrally formed with the tweezer handle 2, the other end of the tweezer arm 3 is integrally formed with a tweezer mouth 4, and an anti-slip groove 301 is provided on the outer wall surface of the tweezer arm 3. Figure 4 As shown, one of the two forceps arms 3 is rotatably connected to a transverse pin shaft 5. Specifically, a transverse pin hole is provided on the forceps arm 3, and the transverse pin shaft 5 passes through the transverse pin hole. A locking member 6 is provided at the inner end of the transverse pin shaft 5 (the inner end of the transverse pin shaft 5 refers to the end of the transverse pin shaft 5 located between the two forceps arms 3). In this embodiment, the locking member 6 is threadedly connected to the inner end of the transverse pin shaft 5 so that the locking member 6 can be removed from the transverse pin shaft 5; an annular ear plate 7 is integrally formed on the locking member 6, and the annular ear plate 7 is attached to the side wall surface of the forceps arm 3 when the locking member 6 locks the transverse pin shaft 5; and a through groove 8 for the locking member 6 to pass through is provided on the other forceps arm 3. 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) is fixedly connected with an arc-shaped connecting member, and the bottom end of the arc-shaped connecting member is provided with a vertical connecting column 10. In this embodiment, the arc-shaped connecting member is an arc-shaped metal spring sheet 9, and the top end of the vertical connecting column 10 is welded to the bottom end of the arc-shaped metal spring sheet 9. In addition, a rubber ring sheet 11 is bonded to the arc-shaped metal spring sheet 9, and the rubber ring sheet 11 is located at the outer periphery of the transverse pin 5. When the locking member 6 locks the transverse spool, the rubber ring sheet 11 is tightly attached to 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, a limiting column 13 is integrally formed at the bottom end of the vertical connecting column 10. The diameter of the limiting column 13 is larger than the diameter of the vertical connecting column 10. The I-shaped slider 12 is provided with a mounting hole. The mounting hole includes a first circular hole and a second circular hole. The limiting column 13 is adapted to the aperture of the second circular hole. The vertical connecting column 10 is adapted to the aperture of the first circular hole. A boss portion 14 is integrally formed on the tongue depressor 1. The boss portion 14 is provided with a T-shaped slide 141 that is slidably matched with the I-shaped slider 12. The T-shaped slide 141 is arranged along the length direction of the tongue depressor 1.

[0035] When in use, the user (doctor or nurse) holds the forceps arm 3, places the forceps mouth 4 and the tongue depressor 1 into the patient's oral cavity, and when a foreign body needs to be clamped, the user pinches the two forceps arms 3 so that the two forceps arms 3 are close to each other, thereby making the two forceps mouths 4 close to each other, thereby clamping the foreign body. In this process, since the transverse pin 5 and the forceps arm 3 will be subject to friction resistance when they rotate relative to each other, the transverse pin 5 will not rotate relative to the forceps arm 3 without the action of external force, so that when the forceps mouth 4 clamps the foreign body, the arc-shaped metal spring piece 9 and the tongue depressor 1 will not affect the object-taking process.

[0036] When tongue depressing is needed, the user holds the forceps arm 3, places the tongue depressor 1 on the patient's tongue, and then presses down the forceps arm 3 to apply pressure to the tongue depressor 1 through the transverse 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 the patient's tongue.

[0037] In addition, when it is necessary to clamp a foreign body while depressing the tongue, after completing the tongue depressing, the user pulls the forceps arm 3 so that the I-shaped slider 12 slides along the length direction of the tongue depressor 1, thereby realizing the movement of the forceps arm 3 in the length direction of the tongue depressor 1, and applies a force to the forceps arm 3 so that the forceps arm 3 rotates in the circumferential direction of the transverse pin 5, and the forceps arm 3 rotates in the circumferential direction of the vertical connecting column 10. Furthermore, after the forceps arm 3 is subjected to force, the arc-shaped metal spring sheet 9 is deformed, and the position of the forceps mouth 4 is adjusted, so that the forceps mouth 4 successfully clamps the foreign body. During this process, the tongue depressor 1 presses down the patient's tongue and does not move. In addition, if the above operation cannot make the forceps mouth 4 close to the foreign body, the position of the tongue depressor 1 can be moved, and the patient's tongue can be pressed down again near the foreign body.

[0038] In summary, in this embodiment, the object-picking function and the tongue-depressing function of the multifunctional tweezers are located at the same end of the tweezers, and the tweezers arm 3 can rotate in the circumference of the transverse pin 5, can rotate in the circumference of the vertical connecting column 10, can move relative to the tongue depressor 1 in the length direction of the tongue depressor 1, and the arc-shaped metal spring sheet 9 can be deformed, and the tweezers arm 3 can move within the deformation range of the arc-shaped metal spring sheet 9. Therefore, the multifunctional tweezers in this embodiment are easy to use, and can be selected from the three working modes of tongue depressing, object-picking, and tongue-picking, thereby improving the efficiency of oral examination. In addition, in this embodiment, after removing the locking member 6, the tongue depressor 1 can be separated from the tweezers arm 3, thereby facilitating cleaning and disinfection work, and also facilitating replacement of the tongue depressor 1 or the tweezers arm 3.

[0039] Embodiment 2

[0040] The difference between this embodiment and the first embodiment is that: Figure 5 As shown, in this embodiment, the bottom end of the arc-shaped metal spring sheet 9 is provided with a through hole for the vertical connection column 10 to pass through, the bottom end of the vertical connection column 10 is integrally formed with a baffle 15, an elastic member 16 is provided between the bottom end of the arc-shaped metal spring sheet 9 and the baffle 15, the top end of the elastic member 16 is welded to the arc-shaped metal spring sheet 9, and the bottom end of the elastic member 16 is welded to the baffle 15. The elastic member 16 in this embodiment is a spring.

[0041] In the present embodiment, when the user applies force to the tweezer arm 3 so that the tweezer arm 3 approaches the tongue depressor 1, in addition to the arc-shaped metal spring piece 9 being deformed to provide movement space for the tweezer arm 3 to approach the tongue depressor 1, the arc-shaped metal spring piece 9 overcomes the elastic force of the elastic member 16 and moves downward as a whole, thereby making the tweezer arm 3 closer to the tongue depressor 1, thereby increasing the movement range of the tweezer mouth 4, so that the tweezer mouth 4 can better clamp foreign objects.
