Description

Technical Field

[0001] The utility model relates to the field of medical technology, in particular to a finger or toe spreading device. Background Art

[0002] When medical staff need to perform surgery, debridement, dressing change, or medication application on toe and finger gaps, such as debridement of diabetic foot, debridement of ulcers and gangrene between toes, medical staff need to manually pry open the patient's adjacent fingers or toes, insert gauze or other objects between the patient's fingers or toes, or have another person assist to separate the adjacent fingers or toes. This not only affects the progress of surgery, debridement, dressing change, and medication application, but also is time-consuming and labor-intensive, affects the exposed area, and is prone to cross infection.

[0003] To solve the above problems, the existing technology has been improved as follows:

[0004] 1. The patent CN201820265582.X provides a twistable toe spacer, which blocks the front view of the toes and brings instability to the operation of medical staff.

[0005] 2. The patent CN201820609244.3 provides a multifunctional interdigital spreader, which only involves the spreading of two fingers or toes and cannot spread and fix several fingers or toes at the same time. Another person is required to assist during the operation. In addition, the structure is too close to the patient's affected area and is prone to contamination of the affected area.

[0006] 3. The patent of CN202321211627.2 provides a device for spreading and fixing adjacent fingers or toes. Although the device can solve the above problems of the above two patents, the fixing components of the structure are fixed on the round rod by manually screwing the fastening bolts, which is time-consuming to operate. In order to fix multiple spreaders in the appropriate position, multiple fixing components may need to be adjusted repeatedly, which requires repeated adjustment of multiple fixing components, which is cumbersome, time-consuming, inefficient, and easy to contaminate the operating area. In addition, the structure uses a round rod with cylindrical plugs at both ends, which is difficult to ensure that the patient's hands or feet are stable and do not move, and cannot play a fixing role, so it is easy to affect the medical staff's operation on the patient's affected area.

[0025] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In the subsequent descriptions, suffixes such as "module" and "component" are only for the convenience of explaining the present invention.

[0026] The utility model discloses a finger or toe spreading device, which comprises: a strip-shaped mounting plate, on one surface of which a plurality of positioning grooves with the same size are uniformly formed; at least two spreading modules, which are mounted at different positions on the mounting plate by cooperating with the positioning grooves at different positions on the mounting plate, so as to spread and fix adjacent fingers or toes; wherein, the spreading module comprises: a fixing component with a positioning block, and the spreading module is mounted on the mounting plate by inserting the positioning block into a positioning groove on the mounting plate; an annular or semi-annular spreader, one end of which is connected with the fixing component, so that its position changes along with the different positions of the fixing component on the mounting plate. Among them, the annular spreader can be an integrally formed circular ring or elliptical ring, or can be a circular ring or elliptical ring composed of two semi-rings that are detachably connected to fine-tune the size. The semi-annular spreader can be a half circular ring or a half elliptical ring, and the opening direction can be any direction for spreading fingers, such as upward, leftward, rightward, and so on. For the convenience of understanding, each of the following embodiments will be described in detail by taking the annular spreader, the right-opening semi-annular spreader, and the left-opening semi-annular spreader as examples.

[0027] Embodiment 1

[0028] See Figure 1a , a finger or toe spreading device of this embodiment comprises: a mounting plate 11 and spreading modules 21 with an annular spreader, 31 with a right-opening semi-annular spreader, and 41 with a left-opening semi-annular spreader, which are mounted on the mounting plate 11. As an alternative, the spreading module can only adopt the spreading module 21 with an annular spreader, or as Figure 1b shown, a part can adopt the spreading module 31 with a right-opening semi-annular spreader, and the other part can adopt the spreading module 41 with a left-opening semi-annular spreader. Figure 1a And Figure 1b shown, the number of spreading modules used is five. In fact, it can be determined according to the number of finger gaps or toe gaps to be processed. For example, if one finger gap needs to be processed, two fingers need to be spread, and at this time, two spreading modules need to be mounted on the mounting plate 11. Also, for special patients, more than five spreading modules can also be mounted on the mounting plate 11.

[0029] See Figure 2 , a plurality of positioning grooves 112 with the same size are uniformly formed on the upper surface of the mounting plate 11, and at least one first bump 113 is arranged on the inner side surface of each positioning groove 112. Figure 1a And Figure 1b shown, the mounting plate 11 is a straight strip plate. As an alternative, it can also be an arc-shaped strip plate.

[0030] See Figure 3a, the expansion module 21 with an annular expander includes: a fixing component and an annular expander 211. The fixing component has a positioning block 212. By inserting the positioning block 212 into the positioning groove 112 opened on the upper surface of the mounting plate 11, the expansion module 21 can be mounted on the mounting plate 11. One end of the annular expander 211 is connected to the fixing component and changes its own position as the fixing component is at different positions on the mounting plate 11. Further, the fixing component of the expansion module 21 includes a positioning block 212 and at least one second bump 213 provided on the side of the positioning block 212. The at least one second bump 213 cooperates with the at least one first bump 113 so that the fixing component of the expansion module 21 is fixed in the positioning groove 112 on the upper surface of the mounting plate 11 in a snap-fit manner. Wherein, the upper surface of the positioning block 212 is connected to one end of the annular expander 211. For example, see Figure 4a , one edge of the upper surface of the positioning block 212 is connected to one end of the expander. The above-mentioned positioning block 212, second bump 213, and annular expander 211 are integrally formed. It should be noted that in order to be able to fix the fixing component of the expansion module 21 in the positioning groove 112 of the mounting plate 11 after inserting it into the positioning groove 112 of the mounting plate 11, the present utility model adopts the method of mutual cooperation between the first bump 113 and the second bump 213. The numbers of both are equal and the positions correspond to each other. Both are made of materials that can be slightly deformed under pressure. During use, when pressing the fixing component of the expansion module 21 into the positioning groove 112, the first bump 113 and the second bump 213 are deformed after extrusion, so that the second bump 213 moves to the lower part of the first bump 113, thereby fixing the expansion module 21 on the mounting plate 11. When disassembling, by pulling out the fixing component outward through the expander 211, the first bump 113 and the second bump 213 are deformed after extrusion, so that the second bump 213 moves to the upper part of the first bump 113, thereby removing the expansion module 21 from the mounting plate 11.

[0031] See Figure 3b, the expansion module 31 with a right-opening semi-circular expander includes: a fixing component and a right-opening semi-circular expander 311. The fixing component has a positioning block 312. By inserting the positioning block 312 into the positioning groove 112 formed on the upper surface of the mounting plate 11, the expansion module 31 can be mounted on the mounting plate 11. One end of the right-opening semi-circular expander 311 is connected to the fixing component and changes its position along with the different positions of the fixing component on the mounting plate 11. Further, the fixing component of the expansion module 31 includes a positioning block 312 and at least one second bump 313 provided on the side surface of the positioning block 312. The at least one second bump 313 cooperates with the at least one first bump 113 so that the fixing component of the expansion module 31 is fixed in the positioning groove 112 on the upper surface of the mounting plate 11 in a snap-fit manner. Among them, the upper surface of the positioning block 312 is connected to one end of the right-opening semi-circular expander 311. For example, see Figure 4b , one edge of the upper surface of the positioning block 312 is connected to one end of the expander 311. The above-mentioned positioning block 312, second bump 313, and expander 311 are integrally formed. It should be noted that in order to be able to fix the fixing component of the expansion module 31 in the positioning groove 112 of the mounting plate 11 after inserting it into the positioning groove 112 of the mounting plate 11, the present invention adopts the method of mutual cooperation between the first bump 113 and the second bump 313. The numbers of both are equal and the positions correspond to each other. Both are made of materials that can be slightly deformed under pressure. During use, when pressing the fixing component of the expansion module 31 into the positioning groove 112, the first bump 113 and the second bump 313 are deformed by extrusion, so that the second bump 313 moves to the lower side of the first bump 113, thereby fixing the expansion module 31 on the mounting plate 11. When disassembling, by pulling out the fixing component of the expansion module 31 outward through the expander 311, the first bump 113 and the second bump 313 are deformed by extrusion, so that the second bump 313 moves to the upper side of the first bump 113, thereby disassembling the expansion module 31 from the mounting plate 11.

[0032] See Figure 3c, the expansion module 41 with a left-opening semi-circular expander includes: a fixing component and a left-opening semi-circular expander 411. The fixing component has a positioning block 412, and by inserting the positioning block 412 into the positioning groove 112 opened on the upper surface of the mounting plate 11, the expansion module 41 can be mounted on the mounting plate 11. One end of the left-opening semi-circular expander 411 is connected to the fixing component and changes its own position with the different positions of the fixing component on the mounting plate 11. Further, the fixing component of the expansion module 41 includes a positioning block 412 and at least one second bump 413 provided on the side surface of the positioning block 412, and the at least one second bump 413 cooperates with the at least one first bump 113 so that the fixing component of the expansion module 41 is fixed in the positioning groove 112 on the upper surface of the mounting plate 11 in a snap-fit manner. Wherein, the upper surface of the positioning block 412 is connected to one end of the left-opening semi-circular expander 411. For example, see Figure 4c , one edge of the upper surface of the positioning block 412 is connected to one end of the expander 411. The above-mentioned positioning block 412, second bump 413, and expander 411 are integrally formed. It should be noted that in order to be able to fix the fixing component of the expansion module 41 in the positioning groove 112 of the mounting plate 11 after inserting it into the positioning groove 112 of the mounting plate 11, the present invention adopts the method of mutual cooperation between the first bump 113 and the second bump 413. The numbers of both are equal and the positions correspond to each other. Both are made of materials that can be slightly deformed under pressure. When in use, during the process of pressing the fixing component of the expansion module 41 into the positioning groove 112, the first bump 113 and the second bump 413 are deformed by extrusion, so that the second bump 413 moves to the lower side of the first bump 113, thereby fixing the expansion module 41 on the mounting plate 11. When disassembling, by pulling out the fixing component of the expansion module 41 outward through the expander 411, the first bump 113 and the second bump 413 are deformed by extrusion, so that the second bump 313 moves to the upper side of the first bump 113, thereby removing the expansion module 31 from the mounting plate 11.

[0033] In Figures 2 to 4c , the expansion module is fixed in the positioning groove 112 by the mutual cooperation of the first bump and the second bump. In practical applications, a known snap structure can also be used.

[0034] Further, a scale indicating the position may also be provided on the upper surface or the side surface along the length direction of the mounting plate 11, and each scale on the scale corresponds to a different positioning groove on the mounting plate 11. By recording the positions of each expansion module on the mounting plate 11 for the patient, each expansion module can be directly installed at the recorded position during subsequent treatment, without repeatedly adjusting the position of the expansion module, further reducing the time-consuming for fixing the above-mentioned expansion module.

[0035] The usage steps of the finger or toe spreading device in this embodiment are as follows:

[0036] Step 1: Determine the number of spreading modules to be used according to the number of fingers or toes to be spread.

[0037] Step 2: According to the distance between adjacent fingers or adjacent toes to be spread, insert and remove the multiple spreading modules determined in the first step so that the multiple spreading modules determined in the first step can be fixed to the appropriate positions on the mounting plate 11.

[0038] Step 3: When the device is not needed, the multiple spreading modules can be directly pulled out from the mounting plate 11 or inserted into other positions for fixation.

[0039] In this embodiment, the lower surface of the mounting plate 11 is a flat surface, which can be placed stably on an operating table. After the adjacent fingers or toes of the patient are spread and fixed, the position of the patient's hand or foot can be ensured to be stable and not easy to move. In addition, this embodiment adopts the cooperation mode of the spreading module and the positioning groove, which is simple to operate, can reduce the time-consuming of fixing the spreader, has higher efficiency, and is not easy to contaminate the operation site.

[0040] Embodiment 2

[0041] See Figure 5 , a finger or toe spreading device in this embodiment includes: a mounting plate 12 and spreading modules 22 with a ring spreader, spreading modules 32 with a right-opening semi-circular spreader, and spreading modules 42 with a left-opening semi-circular spreader mounted on the mounting plate 12. As an alternative, the spreading module can only adopt the spreading module 22 with a ring spreader, or a part can adopt the spreading module 32 with a right-opening semi-circular spreader and another part can adopt the spreading module 42 with a left-opening semi-circular spreader. Figure 5 The number of spreading modules shown is three. In fact, it can be determined according to the number of finger gaps or toe gaps to be processed. For example, if three finger gaps need to be processed, four fingers need to be spread, and at this time, four spreading modules need to be installed on the mounting plate 12. Another example is that for special patients, more than five spreading modules can also be installed on the mounting plate 11.

[0042] See Figure 6 , a plurality of positioning grooves 123 with the same size are evenly opened on the lower surface of the mounting plate 12. It should be noted that Figure 5 and Figure 6 the mounting plate 12 shown is a straight long plate. As an alternative, it can also be an arc-shaped long plate.

The cuboid positioning frame 222 can be sleeved on the mounting plate 12 and can move relative to the mounting plate 12. Its first edge is connected to one end of the spreader 221. The first edge is one of the four edges constituting the upper surface of the cuboid positioning frame 222 that is parallel to the length direction of the mounting plate 12. One edge of the bottom plate 223 is provided with a bushing 2232 so that the bottom plate 223 rotates around the second edge of the cuboid positioning frame 222. One side surface of it is provided with a positioning block 2231 that cooperates with the positioning groove 123 on the lower surface of the mounting plate 12. The second edge is one of the four edges constituting the lower surface of the cuboid positioning frame 222 that is parallel to the length direction of the mounting plate 12, Figure 7a , and this edge is in the same plane as the spreader 221. During use, by rotating the bottom plate 223, the bottom plate 223 is covered on the lower surface of the cuboid positioning frame 222, so that the positioning block 2231 on the bottom plate 223 is inserted into the positioning groove 123 on the lower surface of the mounting plate 12. When it is necessary to move or remove the spreading module 22, it can be achieved by releasing the covering state of the bottom plate 223, that is, pulling out the positioning block 2231 on the bottom plate 223 from the positioning groove 123 on the lower surface of the mounting plate 12. Further, a clamping plate 2234 can be provided at one edge of the bottom plate 223 away from the bushing 2232. The angle formed by the clamping plate 2234 and the bottom plate 223 can be clamped on the third edge of the cuboid positioning frame 222, so that the bottom plate 223 maintains the covering state. The third edge is one of the four edges constituting the lower surface of the cuboid positioning frame 222 that is parallel to the second edge. When it is necessary to move or remove the spreading module 22, by applying an outward and downward force to the clamping plate 2234, the covering state can be released.

Its first edge is connected to one end of the spreader 321, and the first edge is one of the four edges forming the upper surface of the cuboid positioning frame 322 that is parallel to the length direction of the mounting plate 12.

The second edge is one of the four edges forming the lower surface of the cuboid positioning frame 322 that is parallel to the length direction of the mounting plate 12, Figure 7b In this case, this edge is in the same plane as the spreader 321. During use, by rotating the bottom plate 323, the bottom plate 323 is covered on the lower surface of the cuboid positioning frame 322, so that the positioning block 3231 on the bottom plate 323 is inserted into the positioning groove 123 on the lower surface of the mounting plate 12. When it is necessary to move or remove the spreading module 32, it can be achieved by releasing the covering state of the bottom plate 323, that is, pulling out the positioning block 3231 on the bottom plate 323 from the positioning groove 123 on the lower surface of the mounting plate 12. Further, a clamping plate 3234 can be provided at an edge of the bottom plate 323 away from the bushing 3232. The angle formed by the clamping plate 3234 and the bottom plate 323 can be clamped on the third edge of the cuboid positioning frame 322, so that the bottom plate 323 maintains the covering state. The third edge is one of the four edges forming the lower surface of the cuboid positioning frame 322 that is parallel to the second edge. When it is necessary to move or remove the spreading module 32, by applying an outward and downward force to the clamping plate 3234, the covering state can be released.

[0045] See Figure 7c, the spreading module 42 with a left-opening semi-circular spreader includes: a fixing component and a left-opening semi-circular spreader 421. The fixing component includes a cuboid positioning frame 422 and a bottom plate 423, and the spreader 421 is integrally formed with the cuboid positioning frame 422.

One side surface of it is provided with a positioning block 4231 that cooperates with the positioning groove 123 on the lower surface of the mounting plate 12. The second edge is one of the four edges constituting the lower surface of the cuboid positioning frame 422 that is parallel to the length direction of the mounting plate 12, Figure 7c In this case, this edge is in the same plane as the spreader 421. During use, by rotating the bottom plate 423, the bottom plate 423 is covered on the lower surface of the cuboid positioning frame 422, so that the positioning block 4231 on the bottom plate 423 is inserted into the positioning groove 123 on the lower surface of the mounting plate 12. When it is necessary to move or remove the spreading module 42, it can be achieved by releasing the covering state of the bottom plate 423, that is, pulling out the positioning block 4231 on the bottom plate 423 from the positioning groove 123 on the lower surface of the mounting plate 12. Further, a clamping plate 4234 can be provided at an edge of the bottom plate 423 away from the bushing 4232. The included angle formed by the clamping plate 4234 and the bottom plate 423 can be clamped on the third edge of the cuboid positioning frame 422, so that the bottom plate 423 maintains the covering state. The third edge is one of the four edges constituting the lower surface of the cuboid positioning frame 422 that is parallel to the second edge. When it is necessary to move or remove the spreading module 32, by applying an outward and downward force to the clamping plate 4234, the covering state can be released.

[0046] Further, a scale indicating the position can also be provided on the upper surface or the side surface along the length direction of the mounting plate 12. Each scale on the scale corresponds to a different positioning groove 123 on the mounting plate 12. By recording the positions of the respective spreading modules on the mounting plate 12 for the patient, the respective spreading modules can be directly installed at the recorded positions during subsequent treatments without repeatedly adjusting the positions of the spreading modules, further reducing the time-consuming for fixing the above-mentioned spreading modules.

[0047] The usage steps of the finger or toe spreading device in this embodiment are as follows:

[0048] The first step: Determine the number of spreading modules to be used according to the number of fingers or toes to be spread.

[0049] Step 2: Fit the multiple spreading modules determined in Step 1 onto the mounting plate 12, and fix the multiple spreading modules to the appropriate positions on the mounting plate 12 by covering or removing the cover of the bottom plate according to the distance between adjacent fingers or adjacent toes to be spread.

[0050] Step 3: When the device is not needed, the multiple spreading modules can be quickly disassembled from the mounting plate 12 or moved to other positions for fixation directly.

After the adjacent fingers or toes of the patient are spread and fixed, the position of the patient's hand or foot can be ensured to be stable and not easy to move; in addition, this embodiment adopts the method of relative sliding of the spreading module with respect to the mounting plate 12 and the mutual cooperation of the positioning block and the positioning groove, which is simple to operate, can reduce the time-consuming for fixing the spreader, has higher efficiency, and is not easy to contaminate the operation site.

[0052] Embodiment 3

[0053] See Figure 8 , a finger or toe spreading device in this embodiment includes: a mounting plate 13 and spreading modules 23 with an annular spreader, spreading modules 33 with a right-opening semi-annular spreader, and spreading modules 43 with a left-opening semi-annular spreader mounted on the mounting plate 13. As an alternative, the spreading modules can only adopt the spreading modules 23 with an annular spreader, or a part can adopt the spreading modules 33 with a right-opening semi-annular spreader and another part can adopt the spreading modules 43 with a left-opening semi-annular spreader. Figure 8 The number of spreading modules shown in use is three. In fact, it can be determined according to the number of finger gaps or toe gaps to be processed. For example, if three finger gaps need to be processed, four fingers need to be spread, and at this time, four spreading modules need to be installed on the mounting plate 13. Another example is that for special patients, more than five spreading modules can also be installed on the mounting plate 11.

[0054] See Figure 9 , a plurality of positioning grooves 133 with the same size are evenly opened on one side of the long strip-shaped mounting plate 13 along the length direction.

[0058] Further, a scale for indicating the position can also be provided on the upper surface or the side surface along the length direction of the mounting plate 13. Each scale on the scale corresponds to a different positioning groove 133 on the mounting plate 13. By recording the positions of the respective spreading modules on the mounting plate 13 for the patient, the respective spreading modules can be directly installed at the recorded positions during subsequent treatments, without repeatedly adjusting the positions of the spreading modules, further reducing the time consumed for fixing the above-mentioned spreading modules.

[0059] The usage steps of the finger or toe spreading device in this embodiment are as follows:

[0060] The first step: Determine the number of spreading modules to be used according to the number of fingers or toes to be spread.

[0061] Step 2: Sheathe the multiple spreading modules determined in Step 1 on the mounting plate 13, and fix the multiple spreading modules to appropriate positions on the mounting plate 13 by covering or removing the cover of the bottom plate according to the distance between adjacent fingers or adjacent toes to be spread.

[0062] Step 3: When the device is not needed, the multiple spreading modules can be quickly disassembled from the mounting plate 13 or moved to other positions for fixation.

[0063] The lower surfaces of each spreading module in this embodiment are on a plane, enabling the device to be stably placed on an operating table during use. After the adjacent fingers or toes of the patient are spread and fixed, the position of the patient's hand or foot can be ensured to be stable and not easy to move. In addition, this embodiment adopts the method of relative sliding of the spreading module with respect to the mounting plate 13 and the mutual cooperation of the positioning block and the positioning groove, which is simple to operate, can reduce the time-consuming for fixing the spreader, has higher efficiency, and is not easy to contaminate the operation site.

[0064] In the first embodiment, after the positioning block is inserted and fixed in the positioning groove, it can be higher than the notch of the positioning groove. Internal threads can be provided on the side surface of the positioning block parallel to the spreader and higher than the notch, and the internal threads can cooperate with a support rod having external threads at one end to fix the support rod on the side surface. In the second and third embodiments, one side surface of the cuboid positioning frame can have a certain thickness, and internal threads can be provided on this side surface, and the internal threads can cooperate with a support rod having external threads at one end to fix the support rod on the side surface. When the device is used for operations such as surgery, debridement, dressing change, and medicine application in the finger gaps of patients, the support rod can be installed on the spreading module first, and then the spreading module can be fixed on the mounting plate. To be applicable to different finger lengths, support rods of different lengths can be pre-designed, or manually adjustable or electrically adjustable support rods can be used. In this way, when the patient uses the device to spread the fingers, the fingers can be placed on the support rod, especially on the support rod with an appropriate length, improving the comfort of the patient.
