Description

Technical Field

[0001] The present invention relates to the field of medical devices, and further to an electric stapler, and in particular to an electric stapler that records the number of surgeries by changing the color of an indicator light. Background Art

[0002] Most of the electric staplers currently available do not clearly specify the service life of the device, or specify the service life of the device but lack a module to record the number of surgeries performed with the electric stapler.

[0003] In order to avoid excessive use of the electric stapler and the resulting poor cutting and suturing effects, it is necessary to propose an electric stapler with a module that records the number of electric stapler surgeries. When the instrument is nearing the end of its service life, the indicator system can remind the surgeon, thereby ensuring good cutting and suturing effects and reducing the risk of medical accidents. Summary of the Invention

[0004] The present invention provides an electric stapler that records the number of surgeries by changing the color of an indicator light, so as to at least solve the technical problem in the prior art that an electric stapler may produce poor cutting and suturing effects due to excessive use.

[0005] The present invention provides an electric stapler that records the number of surgeries by changing the color of an indicator light. The electric stapler includes a counting switch trigger mechanism, which includes a firing generator, a firing gear, a firing rack, and a counting switch. The firing generator is tooth-engaged with the firing gear, the firing gear is gear-rack engaged with the firing rack, the firing rack is in contact with the counting switch, and the counting switch is triggered by the firing rack.

[0006] Optionally, the firing generator is started to rotate, and the firing rack is driven forward by the firing gear, and the movement of the firing rack triggers the counting switch.

[0007] Optionally, the counting switch trigger mechanism further includes a switch elastic component, which is fixedly mounted on the counting switch, and the firing rack contacts and cooperates with the switch elastic component, so that the movement of the firing rack triggers the counting switch through the switch elastic component.

[0008] Optionally, the switch elastic component is a switch spring.

[0009] Optionally, a notch is provided on the firing rack. When the electric stapler completes the firing stroke and returns to the initial position, the notch on the firing rack causes the switch spring to begin to fall onto the notch. At this time, the counting switch returns to the initial position and the number of surgeries is recorded as one additional time.

[0010] Optionally, the circuit of the electric stapler includes a counting circuit, a decoding circuit and an indicator light circuit, the counting circuit includes a trigger circuit, a shift register and a logic converter, the decoding circuit includes a logic operation circuit, and the indicator light circuit includes an indicator light and a power supply circuit.

[0011] Optionally, the trigger circuit converts the action of the counting switch completing a trigger and returning to the initial state into a rising edge pulse signal; the number of the shift registers is two, and both of the shift registers are configured to add a high-level signal to the input end; the logic converter outputs a high-level signal when the input is a low-level signal, and outputs a low-level signal when the input is a high-level signal.

[0012] Optionally, the logic operation circuit converts the level states of the pins of the two shift registers in the counting circuit into predetermined states, and the number of the states is the same as the color types of the indicator lights.

[0013] Optionally, different colors of the above indicator lights are used for different times of prompts.

[0014] Optionally, when the service life of the electric stapler is N times, the indicator light is green when the electric stapler is fired for the N-2th time, the indicator light is orange when the electric stapler is fired for the N-1th and Nth time, and the indicator light is red when the electric stapler is fired for the N+1th time.

[0015] In response to the above-mentioned deficiencies in the prior art, the present invention adds a counting and indicator light color-changing module based on the reciprocating motion of the firing component during the firing / retraction process. This module can record the number of times the electric stapler has been fired / retracted, so that when the instrument is nearing the end of its service life, the indicator light will change color to remind the operator, thereby ensuring a good cutting and suturing effect and reducing the risk of medical accidents.

[0016] In view of the fact that current electric staplers lack a module for recording the number of times the electric stapler has been used in surgeries, the present invention designs an electric stapler that records the number of surgeries by changing the color of an indicator light. When the electric stapler is nearing the end of its service life, the indicator light will change color to remind the surgeon (issue an alarm color), thereby reducing the risk of medical accidents.

[0027] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided solely to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. Rather, these embodiments are provided to make the disclosure of this application more thorough and complete, and to fully convey the scope of the disclosure of this application to those skilled in the art.

[0028] The present invention is implemented as follows Figures 1 to 7 shown.

[0029] The embodiment of the present invention provides an electric stapler that records the number of surgeries by changing the color of an indicator light. Figure 1As shown, the electric stapler includes a counting switch trigger mechanism, which includes a firing generator 1, a firing gear 2, a firing rack 3 and a counting switch 5. The firing generator 1 is tooth-engaged with the firing gear 2, and the firing gear 2 is gear-rack engaged with the firing rack 3. A notch 31 is provided on the firing rack 3, and a protrusion 52 of the counting switch is provided on the counting switch 5. The notch 31 contacts and cooperates with the protrusion 52 of the counting switch. The counting switch 5 is triggered by the firing rack 3, that is, the counting switch 5 is triggered and disconnected by the firing rack 3, so that a series of circuit reactions occur in the circuit board 6, and the number of surgeries is recorded by the color change of the indicator light. Figure 1 The figure shows an initial position diagram of a counting switch trigger mechanism of an electric stapler provided by an embodiment of the present invention, in which an optional firing rack cooperates with a counting switch to record the number of surgeries by changing the color of an indicator light.

[0030] The key point of triggering and disconnecting the counting switch 5 is whether the protrusion 52 of the counting switch 5 is squeezed.

[0031] Furthermore, the firing generator 1 is started to rotate, and the firing rack 3 is driven forward by the firing gear 2. The movement of the firing rack 3 triggers the counting switch 5. Figure 2 As shown, it is the position of the counting switch triggering mechanism when the counting switch 5 is triggered.

[0032] Further, such as Figure 3 As shown, the counting switch trigger mechanism further includes a switch elastic component 4, which is fixedly mounted on the counting switch 5. The firing rack 3 contacts and cooperates with the switch elastic component 4. The movement of the firing rack 3 triggers the counting switch 5 through the switch elastic component 4. Furthermore, the switch elastic component 4 is a switch shrapnel. Figure 3 That is a schematic diagram of the initial position of the counting switch trigger mechanism including the switch spring 4.

[0033] Further, such as Figure 4 As shown, a notch 31 is provided on the firing rack 3. When the electric stapler completes the firing stroke and returns to the initial position, the notch 31 on the firing rack 3 causes the switch spring 4 to begin to fall onto the notch 31. At this time, the counting switch 5 returns to the initial position and the number of surgeries is recorded as one additional operation. Figure 4 That is, the counting switch 5 is triggered by the switch spring 4, and the position diagram of the counting switch triggering mechanism during the movement process.

[0034] like Figure 5As shown, the protrusion 41 of the switch spring 4 is inserted into the groove 51 of the counting switch 5. The protrusion 41 of the switch spring 4 is fixedly connected to the groove 51 of the counting switch 5. The back-and-forth movement of the switch spring 4 squeezes the protrusion 52 of the counting switch 5, thereby transmitting the signal to the circuit board 6.

[0035] Furthermore, the structure diagram of the switch spring 4 is as follows: Figure 6 As shown, the protrusion 41 of the switch spring 4 is snapped into the groove 51 of the counting switch 5 , so that the protrusion 41 of the switch spring 4 is fixedly connected to the groove 51 of the counting switch 5 .

[0036] Further, such as Figure 7 As shown in the circuit schematic diagram, the circuit of the above-mentioned electric stapler includes a counting circuit, a decoding circuit and an indicator light circuit. The above-mentioned counting circuit includes a trigger circuit, a shift register and a logic converter. The above-mentioned decoding circuit includes a logic operation circuit. The above-mentioned indicator light circuit includes an indicator light and a power supply circuit.

[0037] Furthermore, the trigger circuit converts the action of the counting switch 5 completing a trigger and returning to the initial state into a rising edge pulse signal; the number of the shift registers is two, and both shift registers are configured to add a high-level signal to the input end; the logic converter outputs a high-level signal when the input is a low-level signal, and outputs a low-level signal when the input is a high-level signal.

[0038] Furthermore, the logic operation circuit converts the level states of the pins of the two shift registers in the counting circuit into predetermined states, and the number of the states is the same as the color types of the indicator lights.

[0039] Furthermore, the different colors of the above-mentioned indicator lights are used for different times of prompts.

[0040] Furthermore, when the service life of the electric stapler is N times, the indicator light is green when the electric stapler is fired for the first N-2 times, the indicator light is orange when the electric stapler is fired for the N-1th and Nth times, and the indicator light is red when the electric stapler is fired for the N+1th time. For example, when the service life of the electric stapler is 25 times, the indicator light is green when the electric stapler is fired for the first 23 times, the indicator light is orange when the electric stapler is fired for the 24th and 25th times, and the indicator light is red when the electric stapler is fired for the 26th time.

[0041] The counting switch trigger mechanism includes a firing generator 1, a firing gear 2, a firing rack 3, a switch spring 4 and a counting switch 5, wherein the firing generator 1 is tooth-engaged with the firing gear 2, the firing gear 2 is gear-rack engaged with the firing rack 3, and the firing rack 3, the switch spring 4 and the counting switch 5 are in contact with each other. Figure 1 As shown, the switch spring 4 is a non-essential component and the counting switch 5 can be triggered directly through the firing rack 3 .

[0042] When the operator starts the operation, the above-mentioned firing generator 1 is started to rotate, and the firing rack 3 is driven forward by the above-mentioned firing gear 2. The movement of the above-mentioned firing rack 3 will touch the above-mentioned switch spring piece 4 to make it swing upward, and the above-mentioned counting switch 5 is triggered by the swing of the above-mentioned switch spring piece 4.

[0043] When the device completes the firing stroke and returns to the initial position, the notch 31 on the firing rack 3 causes the switch spring 4 to begin to fall onto the notch 31. At this time, the counting switch 5 returns to the initial state, and the counter records once.

[0044] Circuit: The circuit part includes counting circuit, decoding circuit and indicator light circuit.

[0045] The counting circuit consists of a trigger circuit, two shift registers, and a logic converter. The trigger circuit converts the action of the counting switch 5 returning to its initial state after a single trigger into a rising edge pulse signal. The two shift registers are both configured to have a high-level signal applied to their inputs. Initially, each register bit is at a low level, and the output pin corresponding to each register bit is consistent with the level of that register bit. The reset pins each apply a high-level signal through a resistor. When the reset pins transition from high to low, each register bit in the shift register is reset to its initial low-level state. The logic converter outputs a high-level signal when the input is a low-level signal, and a low-level signal when the input is a high-level signal, thus completing the function of a NOT gate circuit.

[0046] like Figure 7As shown, when the counting switch 5 completes one trigger and returns to the initial state, the trigger circuit converts the trigger signal into a rising edge pulse, which serves as the clock signal of the shift register 1 in the counting circuit, shifting the high level state of its input end to the first bit of the shift register 1, and the output pin corresponding to the bit changes from the initial low level state to the high level state; when the counting switch completes the second trigger and returns to the initial state, the shift register 1 in the counting circuit receives the second clock signal, and the high level state in the first bit of the shift register 1 is transferred to the second bit of the register, and at the same time, the high level state of the input end of the register is transferred to the first bit of the register; and so on, when the counting switch 5 completes the nth (n≧1)th trigger and returns to the initial state, the first n-1 bits of the shift register 1 are all in the high level state, and its n-1th bit will also change It is changed to the high level state of its n-1th bit. At the same time, the rising edge signal of the nth bit of the register from low level to high level is used as the clock input of the shift register 2, so that the first bit of the register is converted to the high level state of the input end; at the same time, the high level state of the nth bit of the shift register 1 is converted into a low level signal through the logic conversion device and applied to the reset pin of the shift register 1, so that each bit of the shift register 1 is restored to the low level state. When the counting switch completes the trigger and returns to the initial state the next time, the first bit of the shift register 1 is converted to the high level of its input end again; and so on. When the counting switch completes the triggering of multiples of n times and returns to the initial state, the shift register 1 is reset and the next bit of the shift register 2 is converted from low level to high level. The state of each register bit of the two shift registers records the number of times the counting switch operates.

[0047] The decoding circuit can be composed of a logic operation circuit to convert the level states of the pins of the two shift registers in the counting circuit into several predetermined states, the number of which is the same as the color types of the indicator lights.

[0048] The indicator light circuit is composed of a color-changing LED and a power supply circuit. The indicator light can change into several colors, which are used for different times of prompting.
