Description

Technical Field

[0001] This invention relates to an electrically controlled safety device and an electric stapler, belonging to the field of medical devices. Background Technology

[0002] A stapler is a medical suturing device typically used to replace manual cutting and suturing of tissues. Existing staplers use a mechanical handle to close the jaws at one end, and then a trigger switch activates a motor to control the cutting blade. However, accidental activation of the trigger switch is common in practical use, necessitating appropriate safety devices to prevent unnecessary damage to the patient's tissues due to misoperation.

[0003] The safety devices of existing electric staplers that control the opening and closing of the jaws via mechanical handles are mostly of the paddle type, which has certain defects in terms of aesthetics and ergonomics, thus posing certain safety hazards.

[0004] In view of this, it is indeed necessary to improve the safety device of the existing electric stapler in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an electronically controlled safety device that is not only safer and can reliably prevent misoperation, but is also more ergonomic.

[0006] To achieve the above objectives, the present invention provides an electronically controlled safety device, comprising:

[0007] case;

[0008] The handle is closed, fitted to the housing, and can rotate relative to the housing under external force;

[0009] The firing assembly is mounted on the housing and can rotate relative to the housing under the action of external force to achieve electric start-up;

[0010] A safety assembly, fitted to the housing and close to the closing handle, includes a first button and a second button located on opposite sides of the housing, and a safety micro switch located close to the first button and the second button, the safety micro switch being configured to be triggered when the first button or the second button is pressed;

[0011] A limiting groove is provided between the first button and the second button, and a first protrusion extending toward the safety component is provided on the closing handle. In the initial state, the first protrusion extends into the limiting groove, the first button and the second button are locked, and the safety micro switch is in a locked state. Pressing the closing handle until the first protrusion disengages from the limiting groove unlocks the safety component. Pressing the first button or the second button triggers the safety micro switch, and the firing component is configured to be activated only after the safety micro switch is triggered.

[0012] As a further improvement of the present invention, the first button and the second button are spaced apart and connected by an elastic member located between the first button and the second button. The first button is provided with a guide portion extending toward the second button, and the second button is provided with a corresponding receiving groove for accommodating the guide portion. The limiting groove is formed between the end of the guide portion and the inner wall of the receiving groove.

[0013] As a further improvement of the present invention, the outer peripheral wall of the first button is provided with a protruding first contact, and the outer peripheral wall of the second button is provided with a protruding second contact. The first contact and the second contact are used to trigger the corresponding safety micro switch when the first button or the second button is pressed.

[0014] As a further improvement of the present invention, the electronically controlled safety device further includes a clamp plate located inside the housing, the closing handle, the firing assembly and the safety assembly are all mounted on the clamp plate, and the safety assembly is located between the closing handle and the firing assembly.

[0015] As a further improvement of the present invention, the clamp plate is provided with two mounting holes for mounting the first button and the second button. The two mounting holes are independent of each other and aligned with each other. The limiting groove is exposed between the two mounting holes. In the initial state, the first protrusion is located between the two mounting holes and extends into the limiting groove.

[0016] As a further improvement of the present invention, the clamping plate is also provided with a mounting groove located above one of the mounting holes and communicating with the mounting hole, the first contact and the second contact both protrude into the mounting groove, and the safety micro switch is housed in the mounting groove.

[0017] As a further improvement of the present invention, the closing handle is also provided with a second protrusion located below the first protrusion. The second protrusion extends toward the firing assembly. In the initial state, the second protrusion abuts against the firing assembly. When the closing handle is pressed, the second protrusion disengages from the firing assembly, the firing assembly is in an unlocked state, and the firing assembly can be pressed to start.

[0018] As a further improvement of the present invention, the firing assembly includes a firing button, a trigger lever, and a firing micro switch. The firing button is exposed below the housing, and the trigger lever and the firing micro switch are both housed within the housing. The firing assembly is configured to press the firing button, which in turn moves the trigger lever to trigger the firing micro switch. The firing micro switch is configured to be allowed to be triggered after the safety micro switch is triggered.

[0019] As a further improvement of the present invention, in the initial state, the second protrusion abuts against the firing button; the firing assembly also includes a tension spring, one end of which is connected to the firing button and the other end of which is connected to the clamp plate.

[0020] Another object of the present invention is to provide an electric stapler having the above-mentioned electronically controlled safety device.

[0021] To achieve the above objectives, the present invention provides an electric stapler, comprising:

[0022] The aforementioned electronically controlled safety device;

[0023] A battery pack assembly, mounted on the housing, powers the electric anastomosis device;

[0024] The anvil assembly is kinetically connected to the closing handle; pressing the closing handle closes the jaws of the anvil assembly.

[0025] The beneficial effects of this invention are as follows: This invention configures the safety component with a first button and a second button located on opposite sides of the housing, and a safety microswitch positioned near the first and second buttons. A limiting groove is provided between the first and second buttons, and a first protrusion extending towards the safety component is correspondingly provided on the closing handle. Thus, in the initial state, the first protrusion can be inserted into the limiting groove to lock the first and second buttons, and the safety microswitch is also locked. Furthermore, the closing handle can be pressed until the first protrusion disengages from the limiting groove, unlocking the safety component. Pressing the first or second button then triggers the safety microswitch, thereby activating the firing component. Compared to existing technologies, the electronically controlled safety device of this invention is safer, reliably prevents misoperation, is more ergonomic, and has a more aesthetically pleasing design.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Please see Figures 1-2 As shown, this invention discloses an electric stapler 100, comprising: a gun body assembly 1, a barrel assembly 2, and an anvil assembly 3. The barrel assembly 2 is located between the gun body assembly 1 and the anvil assembly 3, providing a driving connection between the gun body assembly 1 and the anvil assembly 3. The gun body assembly 1 drives the anvil assembly 3 to close its jaws for suturing, and drives a cutting blade (not shown) located within the anvil assembly 3 to move forward and backward via a rack and pinion transmission to complete the cutting action.

[0038] The gun assembly 1 includes a housing 11, a battery pack assembly 12 and a motor assembly 13 housed inside the housing 11, and a closing handle 14, a firing assembly 15, and a safety assembly 16 mounted on the housing 11. The housing 11, the closing handle 14, the firing assembly 15, and the safety assembly 16 constitute an electronically controlled safety device 200. The battery pack assembly 12 is mounted on the housing 11 and supplies power to the motor assembly 13. When energized, the motor assembly 13 rotates, driving a gear and rack transmission. The cutting blade moves forward and backward under the transmission of the gear and rack to complete the cutting action.

[0039] In this embodiment, the battery pack assembly 12 and the motor assembly 13 are arranged approximately vertically. The motor assembly 13 is located within the grip portion (not labeled) below the housing 11, and the battery pack assembly 12 is located within the housing 11 at the end furthest from the anvil assembly 3. The electronically controlled safety device 200 ensures that the cutting blade performs the cutting action only after the jaws of the anvil assembly 3 are closed, thus preventing accidental operation.

[0040] Combination Figures 3-8 As shown, the closing handle 14 and the firing assembly 15 can rotate relative to the housing 11 under external force. Specifically, pressing the closing handle 14 closes the jaws of the anti-pin assembly 3. Pressing the firing assembly 15 energizes the motor assembly 13, enabling electrical start-up. The safety assembly 16 is located near the closing handle 14 and includes a first button 161 and a second button 162 located on opposite sides of the housing 11, and a safety micro switch 163 located near the first button 161 and the second button 162. The safety micro switch 163 is configured to be triggered when the first button 161 or the second button 162 is pressed. The safety assembly 16 ensures that the closing handle 14, the safety assembly 16, and the firing assembly 15 are operated in the correct sequence, preventing misoperation.

[0041] The first button 161 and the second button 162 are exposed at opposite ends of the housing 11, making them easy to press and more ergonomic, preventing discomfort. A limiting groove 160 is provided between the first button 161 and the second button 162. A corresponding first protrusion 141 extending towards the safety assembly 16 is provided on the closing handle 14. In the initial state, the first protrusion 141 extends into the limiting groove 160, locking the first button 161 and the second button 162, and the safety micro switch 163 is locked. Pressing the closing handle 14 until the first protrusion 141 disengages from the limiting groove 160 unlocks the safety assembly 16. Pressing either the first button 161 or the second button 162 triggers the safety micro switch 163. The firing assembly 15 is configured to activate only after the safety micro switch 163 is triggered. This ensures that the closing handle 14, the safety assembly 16, and the firing assembly 15 are activated in the correct sequence.

[0042] In this embodiment, the first button 161 and the second button 162 are spaced apart and connected by an elastic element 164 located between them, preferably a spring. The first button 161 and the second button 162 are preferably cylindrical, and each has an internal space for accommodating the elastic element 164. Of course, in other alternative embodiments, the first button 161 and the second button 162 may also be prismatic; this is not a limitation.

[0043] The first button 161 has a guide portion 1611 extending toward the second button 162, and the second button 162 has a corresponding receiving groove 1621 for accommodating the guide portion 1611. A limiting groove 160 is formed between the end of the guide portion 1611 and the inner wall of the receiving groove 1621. In the initial state, the first protrusion 141 is located between the end of the guide portion 1611 and the inner wall of the receiving groove 1621, at which time the first button 161 and the second button 162 cannot be pressed. The arrangement of the guide portion 1611 and the receiving groove 1621 further restricts the positional orientation when the first button 161 and the second button 162 are pressed.

[0044] The first button 161 has a protruding first contact 1612 on its outer peripheral wall, and the second button 162 has a protruding second contact on its outer peripheral wall. The first contact 1612 and the second contact 1622 are used to trigger the corresponding safety micro switch 163 when the first button 161 or the second button 162 is pressed. Preferably, the first contact 1612 and the second contact 1622 are located at opposite ends of the first button 161 and the second button 162. This satisfies the requirement that when only one safety micro switch 163 is provided, both the first contact 1612 and the second contact 1622 can trigger the safety micro switch 163. In this embodiment, pressing either the first button 161 or the second button 162 will trigger the safety micro switch 163, meaning that if one button cannot trigger the safety micro switch 163, the other button serves as a backup, thus enhancing safety.

[0045] The electronically controlled safety device 200 also includes a clamping plate 17 located inside the housing 11. The closing handle 14, the firing assembly 15, and the safety assembly 16 are all mounted on the clamping plate 17. The closing handle 14 and the firing assembly 15 are both connected to the clamping plate 17 via a pivot (not labeled) to rotate relative to the clamping plate 17 under external force. The closing handle 14 and the firing assembly 15 are partially exposed below the housing 11 for easy operation. The safety assembly 16 is preferably located between the closing handle 14 and the firing assembly 15. Of course, in other embodiments, the closing handle 14 can also be located between the safety assembly 16 and the firing assembly 15, as long as the safety assembly 16 is positioned close to the closing handle 14; there is no limitation on this.

[0046] The clamping plate 17 has two mounting holes 171 for mounting the first button 161 and the second button 162. The two mounting holes 171 are independent of each other and aligned with each other. The limiting groove 160 is exposed between the two mounting holes 171. In the initial state, the first protrusion 141 is located between the two mounting holes 171 and extends into the limiting groove 160. The clamping plate 17 also has a mounting groove 172 located above one of the mounting holes 171 and communicating with the mounting hole 171. The first contact 1612 and the second contact 1622 both protrude into the mounting groove 172, and the safety micro switch 163 is housed in the mounting groove 172.

[0047] In this embodiment, the mounting groove 172 is located above the first button 161, and the longitudinal length of the first button 161 is less than the longitudinal length of the second button 162. The two ends of the second button 162 are installed within the two mounting holes 171, thus obscuring the gap between the first button 161 and the second button 162. Both the first button 161 and the second button 162 can effectively and stably trigger the safety micro switch 163.

[0048] The firing assembly 15 includes a firing button 151, a trigger lever 152, and a firing micro switch 153. The firing button 151 is exposed below the housing 11. The trigger lever 152 and the firing micro switch 153 are both housed within the housing. The trigger lever 152 is mounted below the firing micro switch 153 on the clamping plate 17. The firing assembly 15 is configured to press the firing button 151, which moves the trigger lever 152 to trigger the firing micro switch 153. The firing micro switch 153 is configured to be allowed to be triggered after the safety micro switch 163 is triggered.

[0049] The circuit control logic is set so that the triggering microswitch 153 can only function after the safety microswitch 163 is triggered. That is, the triggering microswitch 153 can only be activated by pressing the first button 161 or the second button 162, after which the triggering button 151 can be pressed, thus energizing and rotating the motor assembly 13. The triggering assembly 15 also includes a tension spring 154, one end of which is connected to the triggering button 151, and the other end is connected to the clamping plate 17. This ensures that after the external force pressing the triggering button 151 disappears, the triggering button 151 resets, the motor assembly 13 is de-energized and stops rotating, and the cutting blade stops cutting.

[0050] like Figures 9-10 and combined Figure 3 As shown, in another embodiment, the closing handle 14 is further provided with a second protrusion 142 located below the first protrusion 141. The second protrusion 142 extends toward the firing assembly 15. In the initial state, the second protrusion 142 abuts against the firing button 151. When the closing handle 14 is pressed, the second protrusion 142 disengages from the firing button 151, and the firing assembly 15 is in an unlocked state, allowing it to be pressed and activated. The second protrusion 142 can limit the firing assembly 15 in the initial state, ensuring that only the closing handle 14 can be pressed in the initial state, thus improving efficiency.

[0051] In this embodiment, the anvil assembly 3 is tractively connected to the closing handle 14. The closing handle 14 forms a linkage structure through the closing link 143 and the barrel push slider 144. Pressing the closing handle 14 causes the barrel push slider 144 to push the jaws of the anvil assembly 3 to close. The top of the closing handle 14 is provided with an integrally formed drive rod 145. One end of the drive rod 145 is connected to the closing link 143, and the closing link 143 is connected to the barrel push slider 144. The other end of the drive rod 145 is provided with a first limiting structure 1451 so that after the external force pressing the closing handle 14 disappears, the closing handle 14 remains in the pressed state, that is, the jaws of the anvil assembly 3 remain closed.

[0052] Preferably, the housing 11 has push knobs 18 on opposite sides for opening the jaws of the anvil assembly 3. Each push knob 18 has a second limiting structure 181 extending toward the closing handle 14. When the closing handle 14 is pressed, the first limiting structure 1451 engages with the second limiting structure 181, limiting the closing handle 14. Pushing the push knob 18 causes the second limiting structure 181 to shift, thus misaligning with the first limiting structure 1451. The closing handle 14 then resets, and the jaws of the anvil assembly 3 open.

[0053] In summary, the present invention configures the safety component 16 as having a first button 161 and a second button 162 respectively disposed on opposite sides of the housing 11, and a safety micro switch 163 disposed near the first button 161 and the second button 162. A limiting groove 160 is provided between the first button 161 and the second button 162, and a first protrusion 141 extending toward the safety component 16 is correspondingly provided on the closing handle 14. Thus, in the initial state, the first protrusion 141 can be inserted into the limiting groove 160 to lock the first button 161 and the second button 162, at which time the safety micro switch 163 is also locked. Furthermore, by pressing the closing handle 14 until the first protrusion 141 disengages from the limiting groove 160, the safety component 16 is unlocked. Pressing the first button 161 or the second button 162 then triggers the safety micro switch 163, thereby activating the firing component 15. Compared with the prior art, the electronically controlled safety device 200 of the present invention is safer, can reliably avoid misoperation, is more ergonomic, and is more aesthetically pleasing.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
