DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] The stapler is generally composed of a handle assembly and a stapler box assembly. The stapler box assembly is used to clamp the tissue to be cut and sutured. The stapler box assembly is operated by the handle to extrude the staples in the box body and suture the tissue. At the same time, the cutter in the stapler box assembly cuts the tissue from the midline of the suture. Specifically, the stapler box assembly includes a stapler seat and a box body, and a plurality of staples are installed in the box body. One end of the stapler box assembly is used to connect with the handle assembly, and the push block on the handle assembly moves along the length direction of the box body to push the staples out of the box body. The stapler seat and the box body clamp the tissue. When the staples are pushed out of the box body, the ends of the staples contact the stapler seat, so that the staples can suture the tissue between the stapler seat and the box body. The staples are distributed on both sides of the symmetry axis of the box body with the length direction of the box body as the symmetry axis. While the staples suture the tissue, the cutter on the handle assembly moves along the symmetry axis of the box body to cut the tissue. At this time, the tissue is separated into two parts, and the ends of the two parts are sutured by the staples. If the staplers in the cartridge have been partially used or completely used, when the stapler is fired again, the cutter will cut the tissue but cannot suture the tissue synchronously, resulting in a medical accident.

[0032] Reference Figure 1 and Figure 2As shown, a stapler stapler magazine with a prompting function according to an embodiment of the utility model comprises a magazine body 100, a guide groove 200, a slider 300 and a sensing assembly 400. The magazine body 100 has a starting end 110 and a terminal end 120, the starting end 110 and the terminal end 120 are distributed along the length direction of the magazine body 100, the magazine body 100 is provided with a plurality of staples, the plurality of staples are arranged and distributed between the starting end 110 and the terminal end 120, and the starting end 110 is used to dock the stapler handle; the guide groove 200 is arranged in the magazine body 100, the guide groove 200 extends along the arrangement direction of the plurality of staples, and one end of the staple is located in the guide groove 200; the slider 300 is arranged in the guide groove 200, the slider 300 can move along the guide groove 200 and push the staple out of the magazine body 100; the sensing assembly 400 is arranged in the magazine body 100, the sensing assembly 400 is located at the starting end 110, and the slider 300 can change the electrical signal of the sensing assembly 400 when leaving the starting end 110. The stapler stapler magazine with a prompting function in the embodiment of the utility model can prevent the stapler from being triggered accidentally when the staplers in the magazine body are not full.

[0033] The box body 100 is used to dock with the stapler handle, which is generally an electric stapler. After the box body 100 and the stapler handle are docked, the electrical signal of the sensing component 400 can be connected to the handle.

[0034] Among them, the stapler handle is prior art, so the detailed structure of the handle is not described. After the stapler handle is docked with the box body 100, the push block on the stapler handle can abut the slider 300, and the cutter also moves with the movement of the push block. When the tissue is stapled, the push block on the handle abuts the slider 300 and pushes the slider 300 to move, and the moving direction of the push block and the slider 300 is from the starting end 110 to the end 120. When the slider 300 moves in the guide groove 200 on the box body 100, the staples can be pushed out of the box body 100, and then the staples suture the tissue. The position on the tissue to be sutured is synchronously cut by the cutter.

[0035] In some cases, the length of suturing tissue only accounts for half of the length of the box body 100 or less. Take the case that the suturing length accounts for half of the length of the box body 100 as an example, in this case, the slide block 300 only needs to move to half of the length of the box body 100, and the cutter also only moves to half of the length of the box body 100 simultaneously. After the tissue is cut and suturing is completed, the cutter and the push block will be reset, that is, the cutter and the push block will return to the stapler handle, that is, the starting end 110 side. At this time, if the stapler is not replaced with a stapler, it is triggered by mistake after clamping new tissue, and the cutter will cut the tissue, but there is no staple in the box body 100 near the starting end 110, and the tissue cannot be sutured. Since the slider 300 and the push block in the present application are in contact, the reset of the push block does not drive the slider 300 back to the starting end 110, so when the staplers in the cartridge 100 are used, the slider 300 will leave the starting end 110, and the electrical signal of the sensing assembly 400 will change. At this time, after the stapler handle receives the changed electrical signal, the control program will prevent the stapler from firing next time until a new cartridge 100 is replaced. The staplers in the new cartridge 100 are not used, and the slider 300 is at the starting end 110 at this time. The electrical signal received by the stapler handle is different from the electrical signal when the slider 300 leaves the starting end 110, so it can fire.

[0036] It should be understood that the conventional stapler stapler magazine is not provided with the slider 300 in the present application, but directly utilizes the push block of the stapler handle to move and extrude the staples. Therefore, after the cutter and the push block of the stapler handle are reset, the push block returns to the starting end 110. If the sensing component 400 detects the position of the push block, it is impossible to determine whether the staples in the stapler stapler magazine are used.

[0037] Reference Figure 3 As shown, it can be understood that the sensing component 400 includes a magnetic block 410 and a first electrical sensor 420, the magnetic block 410 is arranged on the slider 300, the first electrical sensor 420 is arranged on the box body 100, and the first electrical sensor 420 is located at the starting end 110, the magnetic block 410 can move with the movement of the slider 300, and the moving path of the magnetic block 410 covers the first electrical sensor 420.

[0038] The first electrical sensor 420 can detect changes in the external magnetic field, and then generate an electrical signal associated with the magnetic field strength. Specifically, in some embodiments, the first electrical sensor 420 is a Hall sensor. At this time, the electrical signal generated by the first electrical sensor 420 is a voltage signal. When the magnetic block 410 is at the starting end 110, the position of the magnetic block 410 and the first electrical sensor 420 is closer, and the first electrical sensor 420 can output a voltage value (high voltage). After the staples in the box body 100 are used, that is, after the slider 300 leaves the starting end 110, the voltage value output by the first electrical sensor 420 changes (the voltage value decreases), and the stapler handle will prevent the next firing after receiving the change in the electrical signal until the new box body 100 is replaced. In the new box body 100, the slider 300 is at the starting end 110, and the output voltage value of the first electrical sensor 420 is at a high voltage. It should be understood that after the stapler is fired once, the slider 300 is pushed away from the starting end 110 by the push block, and the push block and the cutting knife are reset (return to the starting end 110), but the slider 300 is still retained in the position where it stayed after the firing and will not return to the starting end 110 with the push block. Therefore, the stapler handle will prevent the next firing until a new cartridge 100 is replaced.

[0039] It can be understood that the first electrical sensor 420 includes a fixed contact and a movable contact that can be attracted by a magnet, and the movable contact is configured so that when the magnetic block 410 is located at the starting end 110, the movable contact is attracted by the magnetic block 410 and maintains a first state, and when the magnetic block 410 is away from the starting end 110, the movable contact is reset and maintains a second state. When the movable contact changes from the first state to the second state, the on and off of the movable contact and the fixed contact can be switched.

[0040] The following are two more specific configuration structures of the moving contact and the fixed contact. It should be understood that the resetting of the moving contact can be achieved by an elastic component, such as a commonly used spring structure.

[0041] It can be understood that in some embodiments, the fixed contact and the moving contact are stacked and spaced apart. When the magnetic block 410 is located at the starting end 110, the fixed contact is located between the moving contact and the magnetic block 410. The magnetic block 410 attracts the moving contact to move and contact the fixed contact. When the magnetic block 410 is away from the starting end 110, the moving contact is reset and disconnected from the fixed contact.

[0042] When the magnetic block 410 is at the starting end 110, the attraction of the magnetic block 410 to the moving contact is the greatest, and the moving contact is attracted by the magnetic block 410 and approaches the magnetic block 410. The fixed contact is located between the moving contact and the magnetic block 410, so when the moving contact moves toward the magnetic block 410, it can contact the fixed contact, thereby achieving the contact between the fixed contact and the moving contact to generate an electrical signal. When the magnetic block 410 leaves the starting end 110, the attraction of the magnetic block 410 to the moving contact weakens, the moving contact is reset, the fixed contact is disconnected from the moving contact, and the electrical signal disappears, and the stapler handle can prevent the next firing.

[0043] It can be understood that the fixed contact and the moving contact are stacked and spaced apart. When the magnetic block 410 is located at the starting end 110, the moving contact is located between the fixed contact and the magnetic block 410. The magnetic block 410 attracts the moving contact to move and disconnects from the fixed contact. When the magnetic block 410 is away from the starting end 110, the moving contact is reset and contacts the fixed contact.

[0044] Similarly, when the magnetic block 410 is at the starting end 110, the attraction of the magnetic block 410 to the moving contact is the greatest. The moving contact is located between the fixed contact and the magnetic block 410. At this time, the moving contact is attracted by the magnetic block 410 and moves toward the magnetic block 410, that is, the moving contact moves away from the fixed contact, resulting in the disconnection of the moving contact and the fixed contact. The fixed contact and the moving contact are disconnected, resulting in the disappearance of the electrical signal. Only when the magnetic block 410 leaves the starting end 110, the moving contact is reset and contacts the fixed contact, and the stapler handle receives the electrical signal to prevent the next firing.

[0045] It is understandable that the sensing component 400 further includes a second electrical sensor 430 , which is disposed on the cartridge body 100 and located at the end 120 , and the moving path of the magnetic block 410 covers the second electrical sensor 430 .

[0046] The second electrical sensor 430 can be combined with the first electrical sensor 420 to determine the position of the slider 300 in the guide groove 200, and can obtain three different position states of the slider 300, namely, the slider 300 is at the starting end 110, the slider 300 is between the starting end 110 and the end 120, and the slider 300 is at the end 120. Different position states of the slider 300 correspond to different electrical signals to assist the stapler handle in determining whether it can be fired.

[0047] It is understandable that the side wall of the guide groove 200 is provided with a one-way guide component 210 , and the one-way guide component 210 is used to limit the slider 300 to move only from the starting end 110 toward the end 120 .

[0048] Reference Figure 4 As shown, specifically, in some embodiments, the one-way guide assembly 210 includes a plurality of bevel guide teeth 211, and the plurality of bevel guide teeth 211 are arranged from the starting end 110 toward the end 120, and the bevel guide teeth 211 have a guiding bevel from the starting end 110 toward the end 120, and the bevel guide teeth 211 have a step surface on the side close to the end 120, and the side wall of the slider 300 is provided with a deformable protrusion 310, and the protrusion 310 is in contact with the bevel guide teeth 211.

[0049] When the slider 300 moves toward the end 120, the protrusion 310 contacts the guide slope of the oblique guide tooth 211 and deforms, and then falls into the step surface. Next, the protrusion 310 contacts the guide slope of the next oblique guide tooth 211 and deforms, and then falls into the next step surface. If the slider 300 has a tendency to move toward the starting end 110, the step surface will block the protrusion 310, thereby preventing the slider 300 from moving toward the starting end 110, achieving a unidirectional movement effect of the slider 300. The slider 300 can only move from the starting end 110 toward the end 120, avoiding the slider 300 returning to the starting end 110 for some reason after the stapler is fired and the staples are consumed, and misjudging that there are staples in the box body 100.

[0050] It is understandable that both side walls of the guide groove 200 are provided with a plurality of inclined guide teeth 211, and both side walls of the slider 300 are provided with protrusions 310, so that the slider 300 is subjected to more balanced force when moving in the guide groove 200, and can further ensure that the slider 300 can only move in one direction.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
