[0022] The present application will be further described in detail below through the accompanying drawings and examples, through which the features and advantages of the present application will become more clear and distinct.
[0023] The word "exemplary" is used exclusively herein to mean "serving as an example, example, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.
[0024] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0025] The embodiment of the present application discloses a phalangeal fixation and support device. Figure 1-4 This device will be described.
[0026] Reference Figure 1 A phalangeal fixing and supporting device includes a connecting frame 1, a placement plate 2, an upper limit member 3 and a lower limit member 4.
[0027] The placement plate 2, the upper limit member 3 and the lower limit member 4 are connected to the connecting frame 1; the placement plate 2 is fixedly arranged, and has a placement surface 21 for placing fingers.
[0028] The upper limit member 3 is fixedly arranged above the placement plate 2 , and the upper limit member 3 has an upper limit surface 31 for blocking the finger from moving toward the placement plate 2 .
[0029] The lower limit member 4 is fixedly arranged below the placement plate 2, and the lower limit member 4 has a lower limit surface 41 for preventing the finger from moving toward the placement plate 2; the angle between the placement surface 21 and the lower limit surface 41 is an acute angle, and the angle between the placement surface 21 and the upper limit surface 31 is an acute angle.
[0030] For ease of explanation, a first direction is defined as the lengthwise direction of the upper limit member 3, also horizontally. In the accompanying drawings, the first direction is represented as the X direction. In practice, the two sides of the placement plate 2 refer to the left and right sides of the placement plate 2 along the first direction; the connecting brackets 1 are symmetrically distributed on both sides of the placement plate 2.
[0031] Specifically, the connecting frame 1 is a frame for mounting the placement plate 2, the upper stopper 3, and the lower stopper 4. The structure of the connecting frame 1 can be determined according to needs. In this embodiment, the connecting frame 1 includes two square frames, the placement plate 2 is fixed between the two square frames, and the upper stopper 3 and the lower stopper 4 are connected between the two square frames.
[0032] In this embodiment, the connecting frame 1 is placed on the desktop when in use, and the connecting frame 1 can be placed stably on the desktop.
[0033] The placement plate 2 is a plate for placing fingers to be tied to the external fixator. The length of the placement plate 2 is set along the first direction, and both ends of the placement plate 2 along the first direction are fixed to the connecting frame 1.
[0034] In this embodiment, the upper limit positioning member 3 is fixed on the connecting frame 1. The upper limit positioning member 3 is located above the placement plate 2. The upper limit positioning member 3 can be a plate or a rod. The structure of the upper limit positioning member 3 in this embodiment should not be understood as a restriction on the upper limit positioning member 3. The structure of the upper limit positioning member 3 only needs to be fixed on the connecting frame 1 and can block the fingers on the palm that are not tied to the external fixator. In this embodiment, the upper limit positioning member 3 is a rod. The specific structure of the upper limit positioning member 3 is described in the following content.
[0035] The lower stopper 4 is fixed to the connecting frame 1. In this embodiment, the lower stopper 4 is hinged below the placement plate 2 and locked to the connecting frame 1 using a locking assembly 5, which will be described in detail later. In another embodiment, the lower stopper 4 can be directly fixed to the connecting frame 1 using screws.
[0036] During use, if the index finger needs to be tied, the middle finger, ring finger and little finger can be placed on the upper limit member 3, and the surface on the upper limit member 3 that contacts the fingers is the upper limit surface 31; the thumb can be placed on the lower limit member 4, and the surface on the lower limit member 4 that contacts the thumb is the lower limit surface 41.
[0037] If the middle finger needs to be tied, the index finger can be placed on the upper limit member 3, and the thumb, middle finger, ring finger and little finger can be placed on the lower limit member 4.
[0038] Different fingers can also be selected to be placed on the upper limit member 3 or the lower limit member 4 according to the specific conditions of the patient's fingers.
[0039] The angle between the placement surface 21 and the lower limit surface 41 is an acute angle, and the angle between the placement surface 21 and the upper limit surface 31 is an acute angle. When the fingers are placed on the placement surface 21, the upper limit surface 31 and the lower limit surface 41 respectively, the angle between two adjacent fingers is an acute angle and will not reach a direct or obtuse angle state, which is suitable for most patients.
[0040] By using the fixing device disclosed in this embodiment, there is a large gap between the fingers placed on the placement surface 21 and the fingers placed on the upper limit surface 31 and the lower limit surface 41, which limits the movement of the patient's fingers during the bandaging process, facilitates the medical staff to perform the bandaging operation, and reduces the impact of the patient's finger movements on the operation.
[0041] The different fingers of the patient are restricted separately, which can match the different fingers of the patient, make the two adjacent fingers more flexible, and cause less restriction on the patient's fingers, help the patient relax, and help improve the bandaging effect.
[0042] Reference Figure 1 As an optional solution, the upper limit member 3 is a limit rod.
[0043] Specifically, the upper limit member 3 is a round rod arranged along the first direction, and the side surface of the upper limit member 3 is a curved surface. The upper limit surface 31 shown in this embodiment can be understood as the circumscribed surface of the contact portion between the finger and the side surface of the upper limit member 3.
[0044] Furthermore, a notch is provided on the side surface of the upper limit member 3 , and a plane formed by the notch of the upper limit member 3 is the upper limit surface 31 in this embodiment.
[0045] The upper limit member 3 is a rod structure with a simple structure. When the finger is placed on the upper limit surface 31 , there is relatively little obstruction above the placement plate 2 , which facilitates the medical staff to perform the binding operation.
[0046] In another embodiment, the upper limit member 3 is a rod with a polygonal or elliptical cross section. In another embodiment, the upper limit member 3 is a strip board.
[0047] Reference Figure 1 As an optional solution, the lower limit member 4 is a limit plate. Specifically, the lower limit member 4 is a rectangular plate.
[0048] The area of the lower limit surface 41 on the lower limit member 4 is relatively large. When operating on a patient, more fingers are generally placed on the lower limit surface 41 and fewer fingers are placed on the upper limit surface 31. The larger the area of the lower limit surface 41, the better the comfort when the patient's fingers contact the lower limit member 4, and the amount of movement of the patient's fingers can be reduced, which is convenient for medical staff to perform binding operations.
[0049] Furthermore, the phalangeal fixation support device also includes a wrist pad 7, which is used to support the patient's wrist. The wrist pad 7 further improves the stability of the patient's fingers when placed on the placement board 2, facilitates the medical staff to perform binding operations, and also improves the patient's comfort.
[0050] Reference Figure 1 As an optional solution, the position where the upper limit position member 3 is connected to the connecting frame 1 includes a first position and a second position; the angle between the upper limit surface 31 of the upper limit position member 3 in the first position and the placement surface 21 is smaller than the angle between the upper limit surface 31 of the upper limit position member 3 in the second position and the placement surface 21.
[0051] The upper limit member 3 is placed in the first position or the second position. When the patient's finger that contacts the upper limit surface 31 needs to be placed upward as much as possible, the upper limit member 3 is fixed in the second position to facilitate bandaging the affected area. When the patient's finger that contacts the upper limit surface 31 has little effect on bandaging, fixing the upper limit member 3 in the first position can improve the comfort of the patient's finger placement.
[0052] Reference Figure 1 As an optional solution, two connecting plates 11 are provided on the connecting frame 1 , and the two connecting plates 11 are symmetrically arranged on both sides of the placement plate 2 .
[0053] Each connecting plate 11 is provided with at least two connecting holes 12, two coaxial connecting holes 12 constitute a group of connecting holes 12, and different groups of connecting holes 12 are parallel to each other; one group of connecting holes 12 is a first group of connecting holes, and the other group of connecting holes 12 is a second group of connecting holes, and the second group of connecting holes is located directly above or at the same height as the first group of connecting holes and close to the wrist.
[0054] The two ends of the upper limit positioning member 3 can be respectively located in the two connection holes 12 of the same group of connection holes. When the upper limit positioning member 3 is located in the first group of connection holes, the upper limit positioning member 3 is in the first position; when the upper limit positioning member 3 is located in the first group of connection holes, the upper limit positioning member 3 is in the second position.
[0055] Specifically, the connecting plate 11 is a plate fixed on the square frame of the connecting frame 1 , and two connecting plates 11 are spaced apart along the first direction and fixed to the two square frames respectively.
[0056] In this embodiment, the connecting plate 11 is provided with twenty connecting holes 12, which are arranged in an array. In this embodiment, there are a total of twenty groups of connecting holes 12. The upper limit member 3 is fixed to the connecting plate 11 by inserting the two ends of the upper limit member 3 into two connecting holes 12 of a group of connecting holes 12, one for each pair.
[0057] After the upper limit member 3 is moved downward or away from the wrist, the angle between the upper limit surface 31 of the upper limit member 3 and the placement surface 21 is reduced, thereby achieving the adjustment of the upper limit member 3 from the second position to the first position.
[0058] Reference Figure 2 As an optional solution, an avoidance groove 32 is provided on the side of the upper limit member 3, and the inner cavity of the avoidance groove 32 is larger than the opening.
[0059] The phalange fixation and support device further includes a positioning assembly 6, which includes a positioning block 61, a sliding block 62, and a spring 63. The sliding block 62 is located within the inner cavity of the avoidance groove 32, and the side surface of the sliding block 62 contacts the side wall of the inner cavity of the avoidance groove 32 and slides along the side wall of the inner cavity of the avoidance groove 32; the spring 63 is disposed between the sliding block 62 and the bottom wall of the inner cavity of the avoidance groove 32 and presses against the sliding block 62 and the bottom wall of the inner cavity of the avoidance groove 32.
[0060] The positioning block 61 is fixed on the sliding block 62. The positioning block 61 is in the shape of a U with the opening facing away from the sliding block 62. The positioning block 61 can move to a third position or a fourth position with the sliding block 62; wherein, the third position is when the sliding block 62 moves toward the bottom wall of the inner cavity of the avoidance groove 32 to the position where the positioning block 61 is located in the avoidance groove 32; the fourth position is when the sliding block 62 moves away from the bottom wall of the inner cavity of the avoidance groove 32 to the position where the positioning block 61 at least partially extends out of the avoidance groove 32, and the opening of the protruding part of the positioning block 61 can be used to engage with both sides of the connecting plate 11.
[0061] Specifically, the avoidance groove 32 is a convex groove with a rectangular opening and a rectangular inner cavity. The two side walls of the opening of the avoidance groove 32 along the first direction are located between the two side walls of the inner cavity of the avoidance groove 32 along the first direction. The two side walls of the opening of the avoidance groove 32 along the circumference of the upper limit member 3 are flush with the two side walls of the inner cavity of the avoidance groove 32 along the circumference of the upper limit member 3.
[0062] The sliding block 62 is a square block, and the four sides of the sliding block 62 are in one-to-one contact with the four side walls of the inner cavity of the avoidance groove 32. The sliding block 62 slides in the inner cavity of the avoidance groove 32 along the depth direction of the avoidance groove 32, which is perpendicular to the first direction.
[0063] The spring clip 63 is a V-shaped spring clip 63. In this embodiment, two spring clips 63 are provided. The two spring clips 63 are arranged at intervals along the first direction. One side of the spring clip 63 is pressed against the bottom wall of the inner cavity of the avoidance groove 32, and the other side is pressed against the bottom wall of the inner cavity of the avoidance groove 32 by the sliding block 62. The force applied by the spring clip 63 to the sliding block 62 can push the sliding block 62 to move toward the opening direction of the avoidance groove 32.
[0064] The positioning block 61 is fixed on the surface of the bottom wall of the inner cavity of the sliding block 62 facing away from the avoidance groove 32. The fixing method can be bolt connection. The four side surfaces of the positioning block 61 are in one-to-one contact with the four side walls of the opening of the avoidance groove 32. The positioning block 61 is a U-shaped block. The size of the U-shaped opening of the positioning block 61 along the first direction is greater than or equal to the thickness of the connecting plate 11 along the first direction.
[0065] Apply a force toward the inner cavity of the avoidance groove 32 to the positioning block 61 by hand, and the positioning block 61 moves toward the inner cavity of the avoidance groove 32 under the action of the connecting plate 11, and the V-shaped spring piece 63 is further compressed until the positioning block 61 is completely moved into the inner cavity of the avoidance groove 32. When the connecting plate 11 is located between the U-shaped openings of the positioning block 61, remove the force applied to the bottom wall of the inner cavity of the avoidance groove 32 applied to the positioning block 61. The positioning block 61 moves along the bottom wall of the inner cavity away from the avoidance groove 32 under the action of the spring piece 63, thereby realizing the clamping connection between the positioning block 61 and the connecting plate 11.
[0066] Furthermore, the positioning block 61 is provided with chamfers at both ends along the first direction toward the middle direction. The chamfers are provided so that when the upper limit member 3 is pushed toward the connecting plate 11 along the first direction, the chamfers of the positioning block 61 first contact the connecting plate 11, and the positioning block 61 is moved toward the inner cavity of the avoidance groove 32 by the action of the connecting plate 11, so that the positioning block 61 can be completely moved into the inner cavity of the avoidance groove 32. When the connecting plate 11 is located between the U-shaped openings of the positioning block 61, the positioning block 61 is moved along the bottom wall away from the inner cavity by the action of the spring 63, thereby achieving the clamping connection between the positioning block 61 and the connecting plate 11.
[0067] Reference Figure 3 and Figure 4 As an optional solution, the lower limit member 4 is hinged to the connecting frame 1, and the hinge axis is set horizontally, and the lower limit member 4 can be rotated to the fifth position or the sixth position.
[0068] The phalange fixing and supporting device further includes a locking assembly 5 ; the locking assembly 5 locks the lower limit member 4 in the fifth position or the sixth position.
[0069] Specifically, the hinge axis between the lower stopper 4 and the connecting frame 1 is a first axis 13, which is arranged along a first direction and connected to one end of the lower stopper 4. The lower stopper 4 can rotate about the first axis 13. When the lower stopper 4 rotates, the inclination angle of the lower stopper surface 41 changes, and the angle between the lower stopper surface 41 and the placement surface 21 changes to accommodate different placement positions of the patient's finger.
[0070] The locking assembly 5 can lock the lower limit member 4 in the fifth position or the sixth position. In this embodiment, the locking assembly 5 can also lock the lower limit member 4 in other positions. The specific structure of the locking assembly 5 in this embodiment is described in detail in the following content.
[0071] In another embodiment, the support frame is provided with a first hole and a second hole. The locking assembly 5 includes a telescopic rod, one end of which is fixedly connected to the lower stopper 4. The other end of the telescopic rod can be inserted into the first hole or the second hole when extended, and can be withdrawn from the first hole or the second hole when shortened. When the end of the telescopic rod, which is distal to the lower stopper 4, is inserted into the first hole or the second hole, the lower stopper 4 is locked in the fifth position or the sixth position.
[0072] In another embodiment, the locking assembly 5 may have other structures, and only needs to be able to lock the lower limit member 4 in at least two positions.
[0073] According to the specific situation of the patient, the lower limit member 4 is locked in one of the fifth position or the sixth position, so that when the patient's fingers are placed, other muscles of the hand are relatively relaxed, thereby facilitating medical personnel to bandage the affected area with an external fixator.
[0074] It should be noted that the locking assembly 5 can also lock the lower limit member 4 in other positions. The more positions the lower limit member 4 is locked in, the more optional positions the patient's fingers can be placed in, and the more relaxed the patient's fingers can be.
[0075] Reference Figure 4 As an optional solution, the locking assembly 5 includes a guide rail 51, a locking rod 52 and a locking member 53. The guide rail 51 is fixed to the connecting frame 1, and an arc groove 511 is formed on the guide rail 51. The axis of the arc groove 511 is coaxial with the hinge axis of the lower limit member 4.
[0076] The locking rod 52 is fixedly connected to the lower limit member 4 , and one end of the locking rod 52 passes through and extends out of the arc groove 511 ; the locking member 53 is threadedly connected to the locking rod 52 and presses and fixes the locking rod 52 on the guide rail 51 .
[0077] Specifically, the guide rail 51 is an arc-shaped rod, the center line of which is the axis of the first shaft 13, and both ends of the guide rail 51 are fixed to the connecting frame 1. The arc groove 511 passes through the guide rail 51 along the first direction, and the center line of the arc groove 511 is the axis of the first shaft 13.
[0078] The locking rod 52 is a round rod extending in the first direction. One end of the locking rod 52 is fixed to the lower stopper 4, and the other end extends through and out of the arcuate slot 511. The end of the locking rod 52 extending out of the arcuate slot 511 is provided with an external thread, and the side surface of the locking rod 52 contacts the sidewall of the arcuate slot 511. When the lower stopper 4 rotates about the first axis 13, the locking rod 52 slides within the arcuate slot 511.
[0079] In this embodiment, the locking member 53 is a locking nut, which is threadedly connected to one end of the locking rod 52 extending out of the arc groove 511. The locking nut is rotated to press against the guide rail 51 to lock the locking rod 52 and the guide rail 51, thereby locking the lower limit member 4.
[0080] Furthermore, the surface of the guide rail 51 facing away from the lower limiting member 4 along the first direction for contacting with the locking member 53 is provided with anti-slip grooves.
[0081] In another embodiment, the locking member 53 may be a locking knob, and a threaded hole cooperating with the locking member 53 is provided on the locking knob.
[0082] Reference Figure 3 Furthermore, two locking assemblies 5 are provided, and the two locking assemblies 5 are located on both sides of the placement plate 2 along the first direction.
[0083] Reference Figure 1 As an optional solution, an arc-shaped placement groove is provided at the upper end of the placement plate 2, and the placement surface 21 is the arc-shaped surface of the placement groove.
[0084] Specifically, the placement groove is lower in the middle and higher at both ends along the first direction. The curvature of the arcuate groove 511 is determined according to design requirements and is only shown schematically in the accompanying drawings. The arcuate surface in this case can be understood as a horizontal plane to facilitate analysis of the relationship between the placement surface 21 and the upper limit surface 31 and the lower limit surface 41.
[0085] In another embodiment, the placement plate 2 is a square plate or a square block, and the upper surface of the placement plate 2 is horizontally arranged, and the upper surface of the placement plate 2 is the placement surface.
[0086] The placement groove is provided so that after the patient's finger is placed on the placement surface 21, it is not easy to swing left and right along the first direction, which makes it easy to determine the position of the finger and keep the finger stable, thereby making it easier for medical staff to use the external fixator to bandage the affected area.
