Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a stapler safety lock structure and a stapler. Background Art

[0002] A stapler is a device used in medicine to replace manual suturing. Its main working principle is to use titanium nails to separate or staple tissues, similar to a stapler.

[0003] When the stapler is in use, the trigger needs to be pulled multiple times. Each time the trigger is pulled, the push rod in the stapler moves axially for a certain distance, so that some of the staples in the stapler magazine in the stapler push clamp close to the end of the stapler main body are squeezed out of the stapler magazine and sutured to the wound position. After multiple pulling of the trigger, the push rod in the stapler moves to the end, and all the staples in the stapler magazine in the stapler push clamp are squeezed out of the stapler magazine and sutured to the wound position, completing the suturing of the wound position.

[0004] Before the above-mentioned suturing process, the push rod also has an open position and a closed position, and the push nail clamp includes a first plate and a second plate set at an angle. When the push rod is in the open position, the first plate and the second plate are set at an angle to form a clamping chamber, and the clamping chamber is used to place the patient's wound. After aligning with the patient's wound, the push rod is adjusted to the closed position by pulling the trigger, so that the first plate and the second plate are closed, and the angle between the two is zero, so as to clamp the patient's wound, and then the safety is opened, and the trigger is repeatedly pulled to perform the above-mentioned suturing process.

[0005] Among them, in the process of adjusting the push rod from the open position to the closed position by pulling the trigger, the push rod can only move in one direction. When the clamping chamber is not aligned with the patient's wound position, the medical staff is required to hold the stapler body with one hand and use the other hand to reset and adjust the push rod on the stapler until it is in the open position. This is inconvenient for medical staff to use, and when not in use, there is a risk that the medical staff accidentally touches the trigger, causing the push rod to drive the clamping chamber to close.

[0045] 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.

[0046] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] In the description of the present utility model, "several" refers to one or more, and "multiple" refers to two or more. If there is a description of "first" or "second", it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0048] 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.

[0049] The stapler is a medical device that replaces manual suturing. Its main working principle is to use titanium staples to separate or staple tissues, similar to a stapler. In the related art, the stapler includes a main unit and a staple pusher. The staple pusher has different specifications and models, and is detachably connected to the main unit to replace different models of staple pushers. The staple pusher contains a staple magazine, which contains staples, similar to the staples of a stapler. The main unit has a transmission rod inside, and the staple pusher has a push rod inside. After the staple pusher is locked and connected to the main unit, the transmission rod is connected to the push rod. Medical staff repeatedly press the trigger on the main unit to make the transmission member move in unison in one direction. The transmission structure of the transmission member is similar to a ratchet structure, which can only move in the first direction and lock after moving. Of course, when the restriction of the transmission member is released, the transmission member can also move in the second direction opposite to the first direction. Among them, in the process of the transmission member moving along the first direction, the transmission member pushes the push rod to move a fixed distance along the first direction, so that the nail push clamp changes from an open state to a closed state, and then in the process of repeatedly squeezing the trigger, the push rod pushes the staples in the nail push clamp downward along the first direction and sutures the wound. By squeezing the trigger multiple times, the push rod moves multiple fixed distances until all the staples in the staple cartridge in the nail push clamp are sutured to the wound position, thereby achieving suturing of the wound position.

[0050] Before suturing, the staple pusher needs to remain in the open state so that the patient's position to be sutured is located in the staple pusher and can be clamped by the staple pusher. When the staple pusher clamps the suture position, the staple pusher sutures the wound with staples, similar to placing paper in a stapler first, and when the stapler clamps the paper, the stapler fixes the paper. During the alignment process, the staple pusher may be triggered by mistake, causing the staple pusher to clamp the patient's position to be sutured. At this time, medical staff need to adjust the stapler to reset the staple pusher to the open state, which is inconvenient to use.

[0051] Reference Figures 1 to 5 As shown, the first embodiment of the utility model proposes a stapler safety lock structure 1000, including: a transmission member 100 and a second magnetic attraction portion 200, the transmission member 100 is used to be connected to the trigger 2200 for transmission, can be driven by the trigger 2200 in a first direction, and can be reset in a second direction opposite to the first direction, the transmission member 100 has an open position and a closed position, the transmission member 100 includes a main body 110 and a first magnetic attraction portion 120 connected to one end of the main body 110 along the second direction; the second magnetic attraction portion 200 is used to The second magnetic part 200 is connected to the housing 2100 and is located at one end of the transmission member 100 along the second direction. The second magnetic part 200 can be magnetically connected to the first magnetic part 120. The transmission member 100 is configured as follows: when the trigger 2200 is subjected to an external force, the transmission member 100 moves along the first direction and moves from the open position to the closed position. In the open position, the stapler clamp 3000 is opened, and the first magnetic part 120 is magnetically connected to the second magnetic part 200. In the closed position, the stapler clamp 3000 is closed, and the first magnetic part 120 is separated from the second magnetic part 200. In the stapler safety lock structure 1000 of this embodiment, the risk of medical staff accidentally touching the trigger 2200 can be reduced, and the convenience of use is improved.

[0052] In this embodiment, the transmission member 100 is arranged in the shell body 2100 of the main body, and a ratchet is provided on the bottom surface of the transmission member 100. The ratchet means that the tooth tops of the teeth of the transmission member 100 are tilted in the same direction, for example, the tooth tops are tilted in the second direction, at this time, the tooth grooves are tilted in the second direction, and a pawl is provided on the top of the trigger 2200. When the trigger 2200 is pressed, the pawl is inserted into the tooth groove along the first direction and drives the transmission member 100 to move along the first direction. The transmission member 100 is fixed and the trigger 2200 returns to its initial position. When it is pressed again, the trigger 2200 drives the transmission member 100 to move in the first direction again, so that the transmission member 100 is driven by the trigger 2200 at intervals in the first direction and moves intermittently for a fixed distance. When the transmission member 100 moves to the extreme position or moves along the first direction, the medical staff can actively control the transmission member 100 to move along the second direction, so that the transmission member 100 is reset to the initial position, so that the medical staff can repeatedly control the transmission member 100 to move along the first direction through the trigger 2200.

[0053] Before the stapler performs suturing, the staple pusher clip 3000 needs to be moved to the patient's position to be sutured. At this time, the staple pusher clip 3000 needs to remain in an open state so that the position to be sutured can be located in the staple pusher clip 3000 and aligned with the staple pusher clip 3000. After alignment, the staple pusher clip 3000 changes from an open state to a closed state to clamp the position to be sutured, which is convenient for subsequent suture operations. The state change of the staple pusher clip 3000 is controlled by the trigger 2200, that is, when the trigger 2200 drives the transmission member 100 to be in an open position, the staple pusher clip 3000 is in an open state; when the trigger 2200 drives the transmission member 100 to be in a closed position, the staple pusher clip 3000 is in a closed state.

[0054] The second magnetic attraction portion 200 is fixed in the shell 2100 and is magnetically connected to the transmission member 100 through the first magnetic attraction portion 120, so that when the transmission member 100 moves along the first direction, it needs to overcome the magnetic attraction force, that is, the force of the trigger 2200 to drive the transmission member 100 to move along the first direction is greater. When the medical staff applies a smaller force to the trigger 2200, the trigger 2200 is not easy to rotate. The medical staff needs to apply a larger force to drive the trigger 2200 to rotate, so that the first magnetic attraction portion 120 is disengaged from the second magnetic attraction portion 200, thereby reducing the risk of the medical staff accidentally touching the trigger 2200 to drive the transmission member 100 to move, and thereby making it difficult for the nail push clamp 3000 to be accidentally triggered to clamp other positions of the patient. Moreover, when the transmission member 100 moves to the closed position, the first magnetic attraction portion 120 and the second magnetic attraction portion 200 are no longer magnetically connected, and the transmission member 100 can be used normally to suture the staples in the staple push clip 3000 to the wound position. The trigger 2200 only needs to apply normal force without increasing the burden on medical staff, making it more convenient to use.

[0055] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the stapler safety lock structure 1000 also includes: an elastic member 300, which is arranged along the first direction, one end of which is connected to the second magnetic attraction portion 200, and the other end is used to be connected to the shell 2100; the elastic member 300 is configured to: when the transmission member 100 moves along the first direction and the first magnetic attraction portion 120 has not separated from the second magnetic attraction portion 200, cancel the external force applied to the trigger 2200, and drive the transmission member 100 to reset to the open position.

[0056] Specifically, the second magnetic attraction part 200 is connected to the shell 2100 through the elastic member 300. When the second magnetic attraction part 200 is magnetically attracted to the first magnetic attraction part 120 and the magnetic attraction force exceeds the elastic force, if the trigger 2200 drives the transmission member 100 to move along the first direction, the second magnetic attraction part 200 will stretch the elastic member 300 and increase the elastic potential energy of the elastic member 300, that is, increase the elastic force applied by the elastic member 300 to the second magnetic attraction part 200. When the elastic force exceeds the magnetic attraction force, the first magnetic attraction part 120 is separated from the second magnetic attraction part 200, and the second magnetic attraction part 200 is reset under the elastic force of the elastic member 300. The elastic member 300 can extend the distance between the second magnetic attraction part 200 and the first magnetic attraction part 120. Within this distance, if the external force applied to the trigger 2200 is withdrawn, the second magnetic attraction part 200 and the first magnetic attraction part 120 will be together under the elastic force of the elastic member 300. It is reset to the open position along the second direction, and if the external force applied to the trigger 2200 continues, the first magnetic part 120 is separated from the second magnetic part 200, and only the second magnetic part 200 is reset to the open position along the second direction under the elastic force of the elastic part 300. Therefore, during use by medical staff, if the trigger 2200 is accidentally touched, the external force application time and application strength of the trigger 2200 are relatively short, and the transmission part 100 can be automatically reset along the second direction under the elastic force of the elastic part 300 and the magnetic attraction of the first magnetic part 120 and the second magnetic part 200; and, when medical staff use it normally, continuously pressing the trigger 2200 will still separate the first magnetic part 120 from the second magnetic part 200, and the first magnetic part 120 and the second magnetic part 200 will not affect the subsequent suturing process, thereby reducing the burden on medical staff to press the trigger 2200.

[0057] For example, when medical staff is using it, if they find that there is a certain deviation between the staple pusher clip 3000 and the suturing position and adjustment is required during the process of squeezing the trigger 2200, and at this time the first magnetic part 120 and the second magnetic part 200 have not yet separated, the medical staff only needs to release the trigger 2200, and the transmission part 100 will automatically reset to the open position, so that the staple pusher clip 3000 is in a fully open state. The medical staff can realign the staple pusher clip 3000 with the position to be sutured without actively adjusting the stapler, which is more convenient to use.

[0058] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the stapler safety lock structure 1000 also includes: a damping member 400, which is arranged along the first direction, one end of which is connected to the second magnetic attraction portion 200, and the other end is used to connect to the shell 2100.

[0059] It is worth understanding that when the elastic potential energy of the elastic member 300 is released, that is, the first magnetic attraction part 120 is separated from the second magnetic attraction part 200 or the first magnetic attraction part 120 and the second magnetic attraction part 200 move together in the second direction driven by the elastic member 300, the damping member 400 absorbs the energy of the reciprocating oscillation of the elastic member 300, thereby reducing the number of oscillations of the elastic member 300 and reducing the risk of collision damage. At the same time, the damping member 400 guides the movement of the elastic member 300 and the second magnetic attraction part 200, thereby improving the stability of the movement of the elastic member 300 and the second magnetic attraction part 200.

[0060] In some specific embodiments of the present invention, the first magnetic portion 120 is embedded in an end surface of the main body 110 along the second direction.

[0061] In this embodiment, the first magnetic attraction part 120 is directly embedded in the end surface of the main body 110, the first magnetic attraction part 120 can be a magnet, and the second magnetic attraction part 200 is a metal part that can be attracted by the magnet, such as iron, nickel, etc.; the second magnetic attraction part 200 can also be a magnet, and the magnetism of the second magnetic attraction part 200 and the opposite surface of the first magnetic attraction part 120 are opposite, so that the second magnetic attraction part 200 can be magnetically connected to the first magnetic attraction part 120.

[0062] As another embodiment, the second magnetic attraction part 200 is a magnet, the first magnetic attraction part 120 is integrally connected to the main body 110, the transmission part 100 is a metal part that can be attracted by a magnet, and the transmission part 100 as a whole can be supported by iron. It is only necessary to set the second magnetic attraction part 200 in the shell 2100 to achieve magnetic attraction. The modification cost of the anastomosis device is lower and the economic benefits that can be achieved are better.

[0063] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the stapler according to the second embodiment of the present invention includes: the safety lock structure 1000 of the first embodiment. It is worth understanding that the safety lock structure 1000 reduces the risk of accidental touch by medical staff and improves the convenience of use.

[0064] Reference Figure 1As shown, in some specific embodiments of the present invention, the stapler also includes: a main unit 2000 and a staple pusher 3000, the main unit 2000 includes a shell 2100 with an inner cavity and a trigger 2200, the safety lock structure 1000 is arranged in the inner cavity, the second magnetic attraction portion 200 is connected to the shell 2100, the trigger 2200 includes a gripping portion and a rotating portion connected to the gripping portion, the rotating portion is rotatably connected to the shell 2100 and is located in the inner cavity, the rotating portion can be connected to the transmission member 100 in a transmission manner to drive the transmission member 100 to move in a first direction, and the gripping portion extends out of the shell 2100; the staple pusher 3000 is connected to the main unit 2000 and is connected to the transmission member 100 in a transmission manner; wherein the transmission member 100 is configured as follows: when moving to an open position, the staple pusher 3000 opens; when moving to a closed position, the staple pusher 3000 closes.

[0065] It is worth understanding that when using the stapler, the medical staff first connects the staple pusher clip 3000 with the main unit 2000 as a whole, installs the staple cartridge in the staple pusher clip 3000, and then controls the transmission member 100 to move through the trigger 2200, so that the staple pusher clip 3000 opens or closes or pushes the staples in the staple cartridge for suturing, thereby controlling the staple pusher clip 3000. When the transmission member 100 moves to the extreme position along the first direction, the medical staff controls the transmission member 100 to move along the second direction through the grip, so that the transmission member 100 can be reset to the open position, so that the staple pusher clip 3000 no longer clamps the suturing position of the patient, and it is convenient to remove the stapler.

[0066] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, a stopper 2110 is provided in the shell 2100, and the stopper 2110 is used to stop the transmission member 100; wherein, the stopper 2110 is configured as follows: in the open position, a side of the stopper 2110 facing the transmission member 100 is flush with a side of the second magnetic attraction portion 200 facing the transmission member 100.

[0067] In this embodiment, the transmission member 100 is limited by the stop member 2110 to limit the extreme position of the transmission member 100 moving along the second direction to avoid excessive movement of the transmission member 100 along the second direction. At the same time, when the stop member 2110 is flush with the second magnetic attraction portion 200, the elastic member 300 can be in a relaxed state, that is, neither stretched nor compressed. When the transmission member 100 moves along the first direction, the elastic member 300 is stretched.

[0068] Reference Figure 3 and Figure 5As shown, in some specific embodiments of the present invention, the shell 2100 is provided with a through hole 2120 along the first direction, the transmission member 100 includes a ratchet bar 130 and a reset member 140 connected to the ratchet bar 130, the ratchet bar 130 is transmission-connected to the pin push clip 3000, and the reset member 140 is passed through the through hole 2120.

[0069] In this embodiment, both sides of the reset member 140 extend out of the through hole 2120 , and medical personnel can hold the extended parts on both sides of the reset member 140 to push the reset member 140 to move, which is convenient for resetting the reset member 140 and more convenient to use.

[0070] Specifically, the reset member 140 includes a connecting portion and a push-grip portion connected to the connecting portion, the push-grip portion extends out of the housing 2100, the connecting portion is located in the inner cavity, and is connected to the ratchet bar 130. The medical staff can push the push-grip portion to move along the second direction, and then drive the ratchet bar 130 to move along the second direction through the connecting portion, so as to realize the reset of the transmission member 100 to the open position along the second direction, so as to open the nail push clip 3000.

[0071] 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.
