Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a motion structure, handle and electric stapler with motion positioning recognition for an electric stapler. Background Technology

[0002] Compared with the results of cutting and suturing tissue using a traditional manual laparoscopic stapler, the anastomosis produced by an electric laparoscopic stapler is smoother and neater, enabling patients to recover faster and better after surgery. Electric staplers have become an industry trend.

[0003] The electric stapler consists of a handle and a staple magazine, connected by a barrel. The handle houses a geared motor, a gear, and a rack, while the barrel contains a firing lever. The geared motor drives the gear to rotate, which in turn drives the rack in a linear motion. The rack moves the firing lever forward and backward, thus moving the staple magazine. After each movement of the staple magazine, the rack retracts, and the geared motor restarts. Current electric staplers use a mechanical limit switch to detect whether the cutting blade has returned to its initial position. This mechanical limit switch requires pressure to activate, and the amount of pressure applied affects its triggering effect, potentially leading to errors in the amount of pressure applied each time and resulting in low accuracy of the rack. Summary of the Invention

[0004] This utility model provides a motion structure, handle, and electric stapler with motion positioning recognition to solve the technical problem of inaccurate firing distance caused by the rack not coinciding with the initial position during retraction.

[0005] On the one hand, the present invention provides an electric stapler with a motion structure for recognizing the position of movement, including... Main support; A detection component, which is fixedly mounted on the main support; A moving component, which is movably mounted on the main support.

[0008] In one embodiment of the present invention, a sliding hole is provided in the main support, and the moving component is disposed in the sliding hole and is movable along the hole direction of the sliding hole; The main support has a mounting hole, the direction of which intersects with the direction of the sliding hole, and extends from the outer wall of the main support into the sliding hole. The detection component is installed in the mounting hole.

[0009] In one embodiment of the present invention, the detection component includes a detection element and a mounting element. The mounting element is used to install the detection element on the main bracket. A portion of the detection element is installed on the mounting element, and another portion of the detection element is located in the mounting hole.

[0010] In one embodiment of this utility model, the detection component is a photoelectric switch, and the triggering unit is a sensing boss protruding from the moving component.

[0011] In one embodiment of the present invention, a sliding hole is provided in the main bracket, the moving member is disposed in the sliding hole and is movable along the hole direction of the sliding hole, and the sensing boss has a guide portion for guiding the sensing boss when the sensing boss enters the sliding hole.

[0012] In one embodiment of the present invention, the guide portion has a guide slope; along the movement direction of the moving member, one end of the guide portion near the sliding hole is the front end, and the other end of the guide portion is the rear end; from the front end to the rear end, the guide slope is inclined outward of the guide portion perpendicular to the movement direction of the moving member.

[0013] On the other hand, this utility model also provides a handle for an electric stapler, including a handle housing and the aforementioned electric stapler with motion positioning recognition.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0022] This invention provides an electric stapler, such as Figure 1 As shown, the electric stapler includes a staple cartridge 400, a barrel 300, a rotating head 200, and a handle 100. The staple cartridge 400 is mounted on the distal end of the barrel 300 and is detachably connected to the barrel 300. The rotating head 200 is rotatably connected to the handle 100, and the rotating head 200 drives the barrel 300 and the staple cartridge 400 to rotate, thereby changing the angle of the staple cartridge 400. The staple cartridge 400 includes a staple chamber, a staple anchor, a cutting blade, and an identification chip. The identification chip on the staple cartridge 400 records information such as the model number and number of uses of the staple cartridge 400.

[0023] like Figure 2 As shown, the gun barrel 300 includes a sleeve 301 and a firing lever 302 located within the sleeve 301. The firing lever 302 drives the nail magazine 400 to move. A probe assembly is provided on the side of the gun barrel 300 that mates with the nail magazine 400. After the nail magazine 400 is inserted axially along the gun barrel 300, the identification chip on the nail magazine 400 contacts the probe assembly and is connected to the rotating head 300 through an input wire connected to the probe assembly.

[0024] Please see Figure 3 The rotating head 200 includes a rotating shell 216 and a rotating conductive structure. The rotating conductive structure includes a rotating component and a slip ring component. The rotating component can rotate axially relative to the slip ring component. During the rotation of the rotating component, the brush 209 of the rotating component is always in contact with the conductive ring 201 of the slip ring component to transmit signals. The identification chip on the nail cartridge 400 is connected to the rotating component via an input wire 217. The slip ring component transmits signals to the main control board 103 inside the handle 100 via an output wire 218. The main control board 103 can read the information from the identification chip on the nail cartridge.

[0025] Please see Figure 2 and Figure 3 The sleeve 301 is fixedly connected to the rotating shell 216. A first shell is provided outside the rotating assembly, and the rotating shell 216 is connected to the first shell. The rotating shell 216 rotates together with the rotating assembly. When the rotating shell 216 rotates, the sleeve 301 rotates together with the rotating shell 216.

[0026] like Figure 4 As shown, the staple cartridge 400 can be equipped with a staple cartridge installation alignment line 404 and a staple cartridge alignment arrow 405, and the gun barrel 300 can be equipped with a gun barrel alignment arrow 303. The staple cartridge alignment arrow 405 and the gun barrel alignment arrow 303 are used to indicate the movement direction of the staple cartridge 400 and the gun barrel 300 during installation, respectively. After the staple cartridge installation alignment line 404 and the gun barrel alignment arrow 303 are aligned, the staple cartridge 400 is inserted into the gun barrel 300. Of course, the alignment marks used for alignment are not limited to lines and arrows, and can also be other forms of marks. This is only an example and should not be regarded as a limitation on the alignment marks. When using an electric stapler, the staple cartridge 400 needs to be connected to the gun barrel 300. The connection process is as follows: first, align the staple cartridge installation alignment line 404 with the gun barrel alignment arrow 303, then insert the staple cartridge 400 into the gun barrel 300 along the axis. After it is fully inserted, rotate the staple cartridge 400. After rotating it to the bottom, the assembly automatically locks the staple cartridge 400.

[0027] Please see Figure 2 and Figure 3The handle housing 100 also houses the main support 101, power unit, geared motor, adapter gear, rack 500, main control board 103, forward button, and reverse button. The front end of the main support 101 is connected to the rear end of the barrel 300 via a rotating head 200. One end of the firing lever 302 is connected to the nail magazine 400, and the other end is connected to the rack 500. The power unit provides power to the geared motor, and the adapter gear, connected to the output of the geared motor, transmits power to the rack 500, causing it to move forward or backward.

[0028] Please see Figure 2 and Figure 3 The rotating conductive structure is sleeved on the main support 101, allowing the rotating head 200 to rotate. When the nail magazine 400 needs to be rotated, hold the handle 100 with one hand and rotate the rotating shell 216 with the other. The rotating shell 216 drives the gun barrel 300 to rotate, thereby rotating the nail magazine 400. During the rotation of the rotating shell 216, the brush 209 rotates relative to the conductive ring 201. The brush 209 is always in contact with the conductive ring 201 during the rotation. The input wire 217 rotates together with the gun barrel 300 and the brush 209, while the slip ring assembly does not rotate.

[0029] Please see Figures 1-4 The push-button switch is triggered by the forward or backward button, sending a signal to the main control board 103. The main control board 103 then sends a signal to control the power unit. The power output from the power unit is transmitted to the geared motor, which drives the rack 500 to move to the left via a connecting gear. The rack 500 pushes the firing lever 302 to move to the left, and the connecting gear then drives the rack 500 to move forward. The sensing protrusion on the rack 500 moves away from the photoelectric switch. The firing lever 302 pushes the cutting blade of the staple cartridge 400 to move to the left. The leftward movement of the cutting blade reduces the angle between the staple chamber and the anchor seat of the staple cartridge 400, thus achieving the closing function. As the cutting blade continues to move forward, it pushes the anastomotic staples in the staple chamber to press against the anchor seat, achieving tissue anastomosis. At the same time, the cutting blade breaks the anastomotic tissue along the middle.

[0030] After the staple cartridge 400 completes tissue anastomosis, pressing the back button triggers a back signal to the main control board 103. The power output from the power unit drives the geared motor to rotate in the opposite direction. The geared motor drives the rack 500 to move to the right via the adapter gear. The rack 500 then drives the firing lever 302 to move to the right until the sensing boss 501 returns to the notch of the photoelectric switch. At this point, the photoelectric switch transmits a signal to the main control board 103, which then controls the motor to stop rotating, thus keeping the rack 500 in its initial position. Once the main control board 103 receives the next firing signal, the rack 500 will move forward again, and this process repeats.

[0031] Please see Figures 5 to 10As shown, this utility model also provides a motion structure for an electric stapler with motion positioning recognition. The motion structure is installed inside the handle housing 102. The motion structure includes a main support 101, a motion component 503, and a detection component 600. The detection component 600 is fixedly mounted on the main support 101, and the motion component 503 is movably mounted on the main support 101. A sliding hole 104 is provided inside the main support 101 along the moving direction of the motion component 503. The main support 101 is generally cylindrical. The sliding hole 104 is coaxially arranged with the main support 101 and serves as a guide to ensure that the motion component 503 moves smoothly along a predetermined trajectory. A trigger unit 507 is provided on the motion component 503. The trigger unit 507 is used to trigger the detection component 600 when the motion component 503 moves to the stop position. The motion trajectory of the trigger unit 507 on the motion component 503 passes through the detection area of ​​the detection component 600. The trigger unit 507 and the detection component 600 cooperate to detect whether the motion component 503 has returned to the correct position.

[0032] In some embodiments, the moving member 503 is generally a rack 500, which moves along its length. The triggering unit 507 is located at the end of the rack 500 near the detection member 600. The rack 500 is reciprocally mounted on the main support 101. When the rack 500 moves forward, part of the rack 500 is located in the sliding hole 104. When the rack 500 retracts to its original position, the entire rack 500 slides completely out of the sliding hole 104, while the component connected to the front end of the rack 500 remains within the sliding hole 104.

[0033] After each backward movement, the rack 500 automatically returns to its preset initial position, preparing for the next forward movement. To ensure that the starting position of the rack 500 is completely consistent for each forward movement, thereby ensuring the high precision of each forward distance, a precise positioning trigger unit 507 is installed on the rack 500. This trigger unit 507 moves synchronously with the rack 500. When the rack 500 returns to its original position, the trigger unit 507 precisely engages with the detection component 600, sending a positioning signal. This design not only improves the operational precision of the stapler but also greatly enhances the safety and controllability of the surgical procedure, making it particularly suitable for surgical scenarios requiring high-precision operation.

[0034] In some embodiments, the trigger unit 507 is located at the front end of the rack 500 in the direction of movement. In this embodiment, the gun barrel 300 is mounted at the front end of the main support 101. The front end refers to the end of the rack 500 close to the gun barrel 300, and the rear end refers to the end of the rack 500 away from the gun barrel 300. When the rack 500 completes its retraction action, the detection component 600 located at the front end of the main support 101 accurately captures the position information of the trigger unit 507, thereby confirming that the rack 500 has fully retracted into place. This front-end detection scheme has the advantages of compact structure and rapid response. Of course, the detection component 600 can also be mounted at the rear end of the handle housing 102, or the detection component 600 can be located at the rear end of the main support 101 by extending the main support 101. Accordingly, in this configuration, the trigger unit 507 needs to be moved to the rear end of the rack 500. This rear-end detection scheme is particularly suitable for instrument designs that require more operating space at the front end.

[0035] Regardless of whether a front-end or back-end detection scheme is used, the working principle and effect are equivalent. When the rack 500 retracts to its original position, the trigger unit 507 will precisely align with the detection component 600, ensuring that the system can accurately determine the reset state of the rack 500. This flexible design allows this invention to adapt to various types of staplers, providing more possibilities for the overall layout of the stapler while ensuring detection accuracy.

[0036] In some embodiments, the detection component 600 is mounted on the main support 101. The front end of the main support 101 adopts a cylindrical structure, which is specifically used to install and fix the rotating head 200 to ensure the stable and reliable rotation function of the stapler. The main support 101 is designed with a sliding hole 104 for the sliding of the rack 500, which provides precise guidance for the reciprocating motion of the rack 500.

[0037] A through-hole 105 is provided on the side of the main support 101. The direction of the mounting hole 105 intersects with the direction of the sliding hole 104. The mounting hole 105 extends from the outer wall of the main support 101 inward to the sliding hole 104, thus forming a detection window. The detection component 600 is precisely positioned through the mounting hole 105, and its installation position ensures that the detection component 600 can monitor the movement state of the rack 500 in real time.

[0038] By setting mounting holes 105 on the main support 101, the detection component 600 will not occupy too much space and will not affect the volume of the stapler. The detection window is directly aligned with the rack 500, eliminating the detection blind zone and achieving high detection accuracy. At the same time, the detection component 600 forms a rigid connection with the main support 101, avoiding detection errors caused by vibration.

[0039] When the rack 500 moves within the sliding hole 104, the detection component 600, through the detection window formed by the mounting hole 105, can capture the signal from the trigger unit 507 on the rack 500 in real time. When the rack 500 retracts to its original position, the trigger unit 507 passes through the detection window, and the detection component 600 immediately sends a positioning signal. This design ensures that the starting position of each surgical operation is completely consistent, providing a reliable guarantee for the accuracy of the surgery. At the same time, the modular design facilitates later maintenance and upgrades / replacements of the detection system.

[0040] In some embodiments, the detection component 600 includes a detection element 601 and a mounting element 602. The detection element 601 is mounted on the mounting element 602, which serves as the base of the detection component 600. The mounting element 602 can be fixed to the main bracket 101 by a threaded connection. The main bracket 101 is provided with threaded holes 106 for mounting the mounting element 602. This ensures the rigidity of the overall structure and the stability of the installation, while also facilitating disassembly and adjustment during later maintenance. Of course, the mounting element 602 can also be mounted on the main bracket 101 in other ways, such as by adhesive.

[0041] The sensing element of the detection component 601 is precisely located within the mounting hole 105, maintaining the optimal detection distance with the trigger unit 507 on the rack 500. The detection component 601, situated inside the mounting hole 105, neither interferes with the normal reciprocating motion of the rack 500 nor fails to capture the position signal of the trigger unit 507 in real time. The modular design allows the detection component 601 to be replaced or upgraded independently without replacing the entire main support 101 structure.

[0042] As the rack 500 moves within the sliding hole 104, the detection element 601 monitors the position of the trigger unit 507 in real time. Once the rack 500 retracts into place, the trigger unit 507 and the detection element 601 exchange signals, accurately determining that the rack 500 has completed its reset. This design provides reliable stroke control for the stapler.

[0043] In some embodiments, a main control board 103 is mounted on the upper part of the main support 101, and the detection component 600 is electrically connected to the main control board 103. The mounting hole 105 is provided on the side wall of the main support 101. The detection component 601 is connected to the main control board 103 through a wire. After the detection component 601 detects a signal, it transmits the signal to the main control board 103, and the main control board 103 controls the rack 500 to stop its backward movement.

[0044] The detection element 601 can be a contact type, such as a micro switch; or it can be a non-contact type, such as a Hall sensor or a photoelectric switch. If the detection element 601 is a photoelectric switch, then the triggering unit 507 is a sensing boss 501 mounted on the rack 500. The photoelectric switch includes an infrared transmitter and a receiver, which are installed at the detection window of the main bracket 101. When the sensing boss 501 moves away from the photoelectric switch, the receiver of the photoelectric switch can receive the signal emitted by the infrared transmitter of the photoelectric switch. When the rack 500 retracts into place, the sensing boss 501 is located between the infrared transmitter and receiver of the photoelectric switch, and the receiver of the photoelectric switch cannot receive the signal emitted by the infrared transmitter of the photoelectric switch.

[0045] The detection element 601 can also be a reed switch, and the trigger unit 507 is a permanent magnet. When the rack 500 retracts, the permanent magnet moves synchronously with the rack 500. When it retracts to its final position, the permanent magnet enters the effective sensing area of ​​the reed switch, and the magnetic field causes the inner contacts of the reed switch to close, generating a clear switching signal. The main control board 103 accurately determines that the rack 500 has completed its reset by detecting the change in the switch state.

[0046] In some embodiments, the rack 500 includes a body portion 504 and serrations 505 disposed on the body portion 504, and a sensing boss 501 is disposed on the side of the body portion 504 away from the serrations 505.

[0047] The main support 101 has a sliding hole 104 at its front end and a sliding channel for the rack 500 at its rear end. The sliding channel communicates with the sliding hole 104. Since the rack 500 needs to slide within the sliding hole 104, a guide portion 506 is provided on the sensing boss 501 to guide the sensing boss 501 when it enters the sliding hole 104, in order to facilitate the smooth entry of the rack 500 from the sliding channel into the sliding hole 104. Specifically, the guide portion 506 is a guide slope 502 located at the front end of the sensing boss 501. The end of the guide portion 506 near the sliding hole 104 is the front end, and the other end is the rear end. From the front end to the rear end, the guide slope 502 is inclined outwards from the direction of movement of the moving component. The angle of the guide slope 502 ensures sufficient guiding performance. When the rack 500 begins to enter the sliding hole 104, the guide slope 502 can effectively guide the rack 500 and the sliding hole 104 to achieve smooth alignment, significantly reducing the hard collision between the sensing protrusion and the end of the sliding hole 104 when the rack 500 slides.

[0048] The handle 100 includes a handle housing 102 and the aforementioned electric stapler with motion positioning recognition. The motion structure is installed inside the handle housing 102, and the front end of the main support 101 extends out of the handle housing 102. A main control board 103 is provided on the main support 101, and the detection component 600 is electrically connected to the main control board 103.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of this invention.
