Description

Technical Field

[0001] The present invention belongs to the technical field of medical instruments, and in particular relates to a handle for a surgical instrument and a surgical instrument. Background Art

[0002] Surgical clip appliers are commonly used to clamp tubular tissue during surgical procedures to prevent leakage of fluid from the tubular tissue.

[0003] Typically, a clip applier includes a clip cartridge assembly, an adapter, and a handle. The clip cartridge assembly is removably mounted on the adapter, which in turn is removably mounted on the handle. Conventionally, the adapter and handle are connected via connectors for signal or current communication. The female and male connectors of the connectors are fixed to the adapter and handle, respectively, making them difficult to disassemble.

[0004] Because the handle is repeatedly used, it is often plugged and unplugged. The male connector has a protruding conductive insert, which is easily damaged by repeated plugging and unplugging of the adapter and handle. Since the male connector is fixed in the adapter, the adapter or handle can only be replaced directly, which increases usage costs and reduces user experience.

[0005] Of course, this problem does not only exist in clip appliers, but also exists in devices that are equipped with a handle and have devices that need to be electrically connected. Summary of the Invention

[0008] (2) Technical solution

[0009] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] In one aspect, the present invention provides a handle for a surgical instrument, comprising a female connector and a male connector on the same side; a slot is provided on the handle, the female connector on the same side is fixed in the slot, and the male connector is inserted into the slot; the male connector has a first conductive plug and a second conductive plug extending in two opposite directions, the first conductive plug being electrically connected to the female connector on the opposite side of a device connected to the handle, and the second conductive plug being electrically connected to the female connector on the same side.

[0011] Preferably, a matching guide and anti-reverse insertion structure is provided between the male connector and the female connector and / or the slot on the same side; the guide and anti-reverse insertion structure includes: a magnetic component group that attracts each other is provided on the female connector and the male connector on the same side, and the magnetic component group includes multiple magnetic components with different magnetic properties; or a magnetic component group that attracts each other is provided on the male connector and the slot in which it is located, and the magnetic component group includes multiple magnetic components with different magnetic properties.

[0012] Preferably, the guiding and anti-reverse insertion structure further includes: the shape of the main shell of the male connector is configured as a non-rotating body, and the shape of the portion of the slot that matches the male connector is configured to match the shape of the main shell; or the side wall of the main shell of the male connector and the inner wall of the slot are provided with matching guide protrusions and guide grooves.

[0013] Preferably, the main shell of the male connector is constructed in a unique directional shape, and the shape of the slot matches the shape of the main shell of the male connector; and the male connector is magnetically connected to the slot or the female connector on the same side through a magnetic member.

[0014] Preferably, the male connector and the female connector on the same side are plugged into each other through matching stepped ends.

[0015] Preferably, the outer notch of the slot is inclined in all directions and is spaced apart from the outer side wall of the male connector, and the outer side wall of the male connector forms an annular groove; the female connector on the same side is inserted into the slot where the male connector is located, wherein magnetic members that attract each other are provided between the side wall of the female connector on the same side and the side wall of the slot, and the outer side wall of the female connector on the same side forms an annular groove.

[0016] Preferably, the male connector is provided with a magnetic member capable of attracting the magnetic member on the female connector on the opposite side.

[0018] Preferably, a slot is provided in the actuator, and the opposite-side female connector is inserted into the slot of the actuator, wherein the outer notch of the slot is inclined in all directions, the outer end side wall of the opposite-side female connector forms an annular groove, and magnetic parts that attract each other are provided between the side wall of the opposite-side female connector and the side wall of the slot in which it is located.

[0019] Preferably, the female connector on the opposite side is provided with a magnetic member that attracts the magnetic member of the male connector.

[0020] (3) Beneficial effects

[0021] The beneficial effects of the present invention are:

[0022] The present invention provides a handle for surgical instruments, which converts the male connector in the prior art into a combination of a heterolateral female connector and a male connector. The heterolateral female connector is fixed in the handle, and the male connector is inserted in the handle and electrically connected to the female connector on the same side of the handle. At the same time, the male connector still remains electrically connected to the original female connector (named "heterolateral female connector" in the present invention). Because the male connector is detachably inserted in the slot, if the male connector is damaged, the male connector can be pulled out of the slot separately for replacement. The cost of a single male connector is much smaller than the overall cost of the handle, so the cost of using a device containing the handle is greatly reduced, which can improve user experience and avoid waste of resources. At the same time, the plug-in connection method also allows the male connector to be quickly installed and removed.

[0023] The present invention provides a surgical instrument that converts the male connector in the prior art into a combination of a heterolateral female connector and a male connector. The male connector can be inserted into the handle and electrically connected to the female connector on the same side. At the same time, the male connector can still maintain an electrical connection with the original female connector (named "heterolateral female connector" in the present invention). Because the male connector can be removably inserted into the slot, if the male connector is damaged, the male connector can be pulled out of the slot and replaced separately. The cost of a separate male connector is much smaller than the overall cost of the handle, so the cost of using a surgical instrument with this handle is greatly reduced, which can improve user experience and avoid waste of resources.

DETAILED DESCRIPTION

[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] See also Figure 1 and Figure 2 This embodiment provides a clip applier including an adapter 1 and a handle 2. The adapter 1 and handle 2 are detachably connected via a conventional plug-in structure. When plugged together, they need to form an electrical connection for transmitting current or signals. This embodiment primarily improves the components that form the electrical connection between the adapter 1 and handle 2, while the plug-in structure between the adapter 1 and handle 2 can adopt any existing technology.

[0031] Specifically, the clip applier of this embodiment further includes a heterolateral female connector 3, a homolateral female connector 4, and a male connector 5. The heterolateral female connector 3 is located in the adapter 1, the male connector 5 and the homolateral female connector 4 are located in the handle 2, and the male connector 5 is located between the heterolateral female connector 3 and the homolateral female connector 4, forming a transitional connector.

[0032] A slot (referred to as the "first slot" for ease of distinction) is provided in the handle 2. The female connector 3 on the opposite side is fixed in the first slot. "Fixed" refers to the operating state and does not necessarily define whether it is removable or non-removable. In the prior art, the female connector 3 on the opposite side is non-removably embedded in the first slot. If the female connector 3 on the opposite side is damaged, the adapter 1 must be replaced. In this embodiment, the female connector 3 on the opposite side is inserted into the first slot and can be removed and replaced.

[0033] Preferably, the main body of the opposite-side female connector 3 is a non-rotating body (preferably a rectangle), and the shape of the first slot matches it. The shape limitation provides a guide for the insertion of the opposite-side female connector 3.

[0034] Preferably, magnetic members 9 are provided on two opposing side walls of the opposite female connector 3, as well as on two opposing side walls of the first slot. The magnetic members on the opposite female connector 3 and the magnetic members on the first slot have opposite magnetic properties, resulting in mutual attraction, thereby securing the opposite female connector 3 in the first slot. A PIN pin is provided on the inner end of the opposite female connector 3 for connection to the PCB board in the adapter 1. The PIN pin is supported in a mounting hole on the inner end of the opposite female connector 3 by an elastic member (e.g., a spring). After the adapter 1 and handle 2 are plugged together, the elastic member is compressed, and its restoring force pushes the PIN pin outward, allowing it to communicate better. Of course, the device used for communication connection is not limited to a PIN pin; an area for communication connection can be provided within the first slot. A conductive spring is provided on the opposite female connector 3. When the conductive spring is in a free state, it protrudes from the outer surface of the opposite female connector 3. When the opposite female connector 3 is inserted into the first slot, the conductive spring is pressed downward and pressed against the communication area within the first slot.

[0035] In other embodiments, the magnetic member on the opposite-side female connector 3 can also be disposed on the inner end of the opposite-side female connector 3. However, since the magnetic member used in this embodiment is a magnetic sheet attached to the opposite-side female connector 3, affixing the magnetic member to the side of the opposite-side female connector 3 can prevent the magnetic member from falling during long-term use. Of course, for example, the magnetic member can be embedded in the opposite-side female connector 3 using an inlay method. In this case, since the inlay method can provide six degrees of freedom for the magnetic member, the magnetic member can be disposed on the inner end of the opposite-side female connector 3 or on two opposite side walls without worrying about the problem of the magnetic member falling.

[0036] Preferably, a plurality of magnetic members are provided on the opposite-side female connector 3, and the magnetism of some of the magnetic members can be opposite to that of other magnetic members. In this way, when the opposite-side female connector 3 is inserted into the slot in the wrong direction, the operator can clearly feel the repulsive force, and when it is adjusted to the correct direction, the operator can clearly feel the attractive force. Such a design is conducive to the convenient and correct installation of the opposite-side female connector 3, and has a fool-proof effect. For example, in this embodiment, two magnetic members are provided on each of the two opposite sides of the opposite-side female connector 3, the two magnetic members on one side are positive, and the two magnetic members on the other side are negative. Alternatively, when the magnetic members are provided on the inner end surface of the opposite-side female connector 3, three magnetic members can be provided in an equilateral triangle arrangement, and one of the three magnetic members has the opposite magnetism of the other two. This can guide the opposite-side female connector 3 to automatically rotate to the appropriate position, and has a fool-proof effect.

[0037] Of course, other structures can also be used to achieve foolproofing and connection functions.

[0038] For example, a snap-on structure can be used instead of magnetic attraction, and the snap-on structure can achieve positioning and fixation at the same time. Specifically, a protruding hook is integrally injection-molded on the opposite-side female connector 3, a socket is provided in the first slot, a hook groove is formed on one side of the hook, and a convex hook that is inserted into the hook groove is injection-molded in the socket. The insertion end of the hook is gradually tapered to play a guiding role. The advantage of this snap-on structure is that it not only achieves a stable connection, but also prevents reverse insertion. Furthermore, the outer shape of the inner end of the opposite-side female connector 3 is rectangular, and the cross-section of the first slot is also rectangular, which can further prompt the operator to insert the direction. Alternatively, two rectangular columns can be set on the opposite-side female connector 3 at the same time as the hook, and the length directions of the two rectangular columns are perpendicular. At the same time, holes are set in the first slot that are oriented in a manner that matches the two rectangular columns, which can further prevent reverse insertion. When the rectangular column protrudes from the hook, the operator can have a sense of reverse insertion in advance and can make timely adjustments.

[0039] For another example, a guide groove and guide protrusion with a unique orientation can be provided between the opposite female connector 3 and the first slot, so that the opposite female connector 3 can only be inserted in this single orientation. For example, prisms can be provided in the vertical direction of the side wall of the opposite female connector 3 to ensure accurate alignment of the opposite female connector 3 with the first slot and the electrical connection. In this case, the main housing of the opposite female connector 3 can have a relatively simple shape, such as a cylinder.

[0040] For another example, an asymmetric plug-in block is provided to plug into a slot on a side wall of the first slot or a jack on the female connector 3 on the opposite side.

[0041] For another example, a rod is provided on the end face of the opposite-side female connector 3 facing the first slot, and a socket is provided on the first slot. The rod is inserted into the socket, and the end of the rod has a through hole extending in a direction perpendicular to the direction of extension of the rod. The end of the socket in the female connector has a locking rod supported by a spring. When the rod is inserted into the socket, the locking rod enters the through hole, locking the first slot and the opposite-side female connector 3. At this time, the rod and the socket also constitute a guide structure. The connection structure itself has an audible feedback when it is in place, for example, the "click" sound formed by the locking rod hitting the wall of the socket. Alternatively, the connection structure can also be a protrusion provided on the opposite-side female connector 3 and a groove provided on the side wall of the first slot. The protrusion and the groove cooperate to form a snap connection, and a "click" sound is emitted when it is in place.

[0042] Thus, the guide and anti-reverse insertion structure can be composed of two independent structures or just one structure. If the guide and anti-reverse insertion structure is a single structure, it can be set on the opposite-side female connector 3 or in the first slot. If the guide and anti-reverse insertion structure is two structures, they can be set on either the opposite-side female connector 3 or the first slot, or they can be set in both the opposite-side female connector 3 and the first slot.

[0043] For another example, the main body shell of the opposite-side female connector 3 is constructed in a single directional shape, such as a trapezoidal, crescent-shaped, arc-shaped, etc., which can only be inserted in one direction. In this way, other guiding structures can be omitted, and only a simple connection structure (such as a magnetic connection) can be used for connection.

[0044] In summary, returning to the structure shown in the diagram of this embodiment, since the opposite-side female connector 3 is already constrained within the adapter 1 after the adapter 1 and handle 2 are plugged in, the simple method of connector shape setting and paired reverse magnetic attraction can achieve the installation stability requirements of the opposite-side female connector 3, while also achieving foolproof installation and guided installation, and has a simple structure, low cost, and quick installation. Of course, for the purpose of pursuing a more stable connection, other existing guiding structures and anti-reverse insertion (foolproofing) structures and connection structures, as exemplified and not exemplified above, can also be adopted to replace the above-mentioned connector shape setting and paired reverse magnetic attraction method.

[0045] Of course, the above structure is generally applicable to situations where the insertion orientation of the hetero-lateral female connector 3 is fixed, such as when the electrical connection structure arrays on the inside and outside of the hetero-lateral female connector 3 are different. However, another embodiment is that when the hetero-lateral female connector 3 is symmetrical inside and outside and front and back, it can simply use the appropriate matching of the main body shape of the hetero-lateral female connector 3 with the shape of the first slot and magnetic attraction or other connection structure.

[0046] Furthermore, handle 2 is provided with a slot (referred to as the "second slot" for ease of distinction). The ipsilateral female connector 4 is fixed in the second slot ("fixed" refers to the operating state and does not necessarily mean removable or non-removable). The male connector 5 is also inserted into the second slot and located outside the ipsilateral female connector 4, allowing for removal and replacement. The ipsilateral female connector 4 and male connector 5 are described in detail below.

[0047] In this embodiment, the female connector 4 on the same side is specifically inserted into the second slot and can be pulled out and replaced.

[0048] Preferably, the main body of the female connector 4 on the same side is in a non-rotating shape (preferably a rectangle), and the shape of the second slot matches it. The shape limitation provides a guide for the insertion of the female connector 4 on the same side.

[0049] Preferably, magnetic members 10 are provided on two opposing side walls of the same-side female connector 4, and also on two opposing side walls of the second slot. The magnetic members 10 on the same-side female connector 4 and the magnetic members on the second slot have opposite magnetic properties, and the two attract each other, thereby securing the same-side female connector 4 in the second slot. The magnetic member 10 on the same-side female connector 4 can also be provided at the inner end of the same-side female connector 4, but placing the magnetic member 10 on the side of the same-side female connector 4 can prevent the magnetic member from falling during long-term use. Of course, for example, the magnetic member 10 can be embedded in the same-side female connector 4 using an inlay method. In this case, because the inlay method can limit the magnetic member 10 in six degrees of freedom, the magnetic member 10 can be placed at the inner end of the same-side female connector 4 or on two opposing side walls, without having to worry about it falling. When the magnetic member 10 is placed at the inner end of the same-side female connector 4, the corresponding magnetic member is placed in the second slot.

[0050] Preferably, multiple magnetic members 10 are provided on the female connector 4 on the same side, and the magnetism of some of the magnetic members 10 is opposite to that of other magnetic members 10. For example, in this embodiment, two magnetic members 10 are provided on each of the two opposite sides of the female connector 4 on the same side, with the two magnetic members 10 on one side being positive and the two magnetic members 10 on the other side being negative. In this way, if the female connector 4 on the same side is inserted into the slot in the wrong direction, the operator can clearly feel the repulsive force, and when it is adjusted to the correct direction, the operator can clearly feel the attractive force. Such a design facilitates convenient and correct installation and has a fool-proof effect. Alternatively, when the magnetic members are provided on the inner end surface of the female connector 4 on the same side, three magnetic members can be provided in an equilateral triangle arrangement, with one of the three magnetic members having opposite magnetism to the other two. This can guide the female connector 4 on the same side to automatically rotate to the appropriate position, thus having a fool-proof effect.

[0051] Of course, other structures can also be used to achieve foolproofing and connection functions.

[0052] For example, a snap-on structure can be used instead of magnetic attraction, and the snap-on structure can achieve positioning and fixation at the same time. Specifically, a protruding hook is integrally injection-molded on the female connector 4 on the same side, and a socket is provided in the second slot. A hook groove is formed on one side of the hook, and a convex hook that fits into the hook groove is injection-molded in the socket. The insertion end of the hook is tapered to play a guiding role. The advantage of this snap-on structure is that it not only achieves a stable connection, but also prevents reverse insertion. Furthermore, the outer shape of the inner end of the female connector 4 on the same side is rectangular, and the cross-section of the second slot is also rectangular, which can further prompt the operator to the insertion direction. Alternatively, two rectangular columns can be set on the female connector 4 on the same side at the same time as the hook is set, and the length directions of the two rectangular columns are perpendicular. At the same time, holes are set in the second slot that are oriented in a manner that matches the two rectangular columns, which can further prevent reverse insertion. When the rectangular column protrudes from the hook, the operator can have a sense of reverse insertion in advance and can make timely adjustments.

[0053] For another example, a guide groove and a guide protrusion with a unique orientation are provided between the female connector 4 on the same side and the second slot, so that the female connector 4 on the same side can only be inserted along this single orientation. For example, a prism is provided in the vertical direction of the side wall of the female connector 4 on the same side to ensure that the female connector 4 on the same side is accurately aligned with the second slot and the electrical connection. In this case, referring to Figure 3 The shape of the main shell of the female connector 4 on the same side can be relatively simple, such as cylindrical.

[0054] For another example, an asymmetric plug-in block is provided to plug into the slot on the side wall of the second slot or the jack on the female connector 4 on the same side.

[0055] For another example, a rod is provided on the end face of the ipsilateral female connector 4 that faces the second slot, and a socket is provided on the second slot. The rod is inserted into the socket, and the end of the rod has a through hole extending perpendicularly to the rod's direction of extension. The end of the socket in the female connector has a locking rod supported by a spring. When the rod is inserted into the socket, the locking rod enters the through hole, locking the second slot and the ipsilateral female connector 4. At this time, the rod and the socket also form a guide structure. This connection structure itself has an audible feedback when it is in place, for example, a "click" sound caused by the locking rod hitting the wall of the socket. Alternatively, the connection structure can also be provided with a protrusion on the ipsilateral female connector 4 and a groove on the side wall of the second slot. The protrusion and the groove cooperate to form a snap connection, and a "click" sound is emitted when it is in place.

[0056] Thus, the guide and anti-reverse insertion structure can be composed of two independent structures or just one structure. If the guide and anti-reverse insertion structure is a single structure, it can be set on the female connector 4 on the same side or in the second slot. If the guide and anti-reverse insertion structure is two structures, it can be set on one of the female connector 4 and the second slot on the same side, or it can be set in the female connector 4 and the second slot on the same side.

[0057] For another example, the main body shell of the female connector 4 on the same side is constructed into a single directional shape, such as a trapezoidal, crescent-shaped, arc-shaped, etc., which can only be inserted in one direction. In this way, other guiding structures can be omitted, and only a simple connection structure (such as a magnetic connection) can be used for connection.

[0058] The inner end of the ipsilateral female connector 4 is provided with a PIN pin that connects to the PCB board in the handle 2. The PIN pin is supported in the mounting hole at the inner end of the ipsilateral female connector 4 by an elastic member (e.g., a spring). After the adapter 1 and the handle 2 are plugged together, the elastic member is compressed, and the restoring force of the elastic member pushes the PIN pin outward, allowing the PIN pin to communicate better. Of course, the device used for communication connection is not limited to the PIN pin. An area for communication connection can be provided in the second slot. The ipsilateral female connector 4 is provided with a conductive spring. When the conductive spring is in a free state, it protrudes from the outer surface of the ipsilateral female connector 4. When the ipsilateral female connector 4 is inserted into the second slot, the conductive spring is pressed downward and pressed against the communication area in the second slot.

[0059] Specifically, the opposite-side female connector 3 and the same-side female connector 4 are located on either side of the male connector 5. The male connector 5 has a first conductive plug 6 and a second conductive plug 7 (preferably pins) extending in opposite directions. The opposite-side female connector 3 also has a first conductive socket, and the same-side female connector 4 has a second conductive socket. The "conductivity" mentioned above can refer to the transmission of current or signals. When the adapter 1 and handle 2 are plugged in, the first conductive plug 6 plugs into the first conductive socket to achieve electrical connection, and the second conductive plug 7 plugs into the second conductive socket to achieve electrical connection. Of course, the conductive sockets in the opposite-side female connector 3 and the same-side female connector 4 can also be replaced with conductive pins or conductive surfaces to connect with the conductive plugs.

[0060] The PIN pins on both sides of the male connector 5 are supported in their mounting holes by elastic members (e.g., springs). After the adapter 1 and the handle 2 are plugged in, the elastic members are compressed, and the restoring force of the elastic members pushes the PIN pins outward, allowing the PIN pins to communicate better. Of course, the devices used for communication connection are not limited to PIN pins. Areas for communication connection can be set within the first conductive socket and the second conductive socket. The first conductive plug 6 and the second conductive plug 7 are conductive springs. When the conductive springs are in a free state, they protrude from the outer surface of the male connector 5. When the male connector 5 is connected to the opposite-side female connector 3 and the same-side female connector 4, the conductive springs are pressed down by the inner walls of the conductive sockets and tightly pressed against the communication area within the conductive sockets.

[0061] The main body of the male connector 5 is shaped like a non-rotating body (preferably a rectangle). The portion of the second slot that mates with the male connector 5 is shaped to match the main body. This matching shape creates an insertion guide between the male connector 5 and the second slot. At the connection between the male connector 5 and the ipsilateral female connector 4, the male connector 5 has a stepped inner end, while the ipsilateral female connector 4 has a matching stepped outer end. These stepped inner and outer ends plug into each other, positioning and securing the male connector 5 and the ipsilateral female connector 4.

[0062] In addition, a magnetic assembly is provided on the side of the main housing of the male connector 5 that faces the female connector 4 on the same side. This magnetic assembly includes two magnetic members with opposite magnetic properties (not shown in the figure). In conjunction with this, a magnetic assembly is provided on the side of the main housing of the female connector 4 on the same side that faces the male connector 5. This magnetic assembly and the magnetic assembly on the male connector 5 are mutually attracted to each other. Specifically, the magnetic assembly on the female connector 4 on the same side also includes two magnetic members with opposite magnetic properties. The male magnetic member in the magnetic assembly of the female connector 4 on the same side is attracted to the female magnetic member in the magnetic assembly of the male connector 5, and the female magnetic member in the magnetic assembly of the female connector 4 on the same side is attracted to the male magnetic member in the magnetic assembly of the male connector 5. In this way, the matching magnetic members attract each other to form a connection structure, and the arrangement of the opposing magnetic members forms an anti-reverse insertion structure. If the male connector 5 is inserted into the slot in the wrong direction, the operator can clearly feel the repulsive force. When it is adjusted to the correct direction, the operator can clearly feel the attractive force. Such a design is conducive to convenient and correct installation. Of course, the number of magnetic members in the magnetic member group is not limited to two, and can be multiple, and the magnetic properties of some of them are different from those of other parts.

[0063] In summary, in this embodiment, a connection structure and an anti-reverse insertion structure are provided between the male connector 5 and the ipsilateral female connector 4, and a matching guide structure is provided between the male connector 5 and the second slot. This demonstrates that the simple arrangement of magnetic components and the matching of the connector and slot shapes simultaneously achieve the three functions of connection, guidance, and anti-reverse insertion. Since the male connector 5 is already restrained within the adapter 1 when the adapter 1 and handle 2 are plugged together, the simple configuration of the connector shape and paired reverse magnetic attraction achieves the required installation stability for the male connector 5, while simultaneously achieving foolproof and guided installation. Furthermore, this design is simple, cost-effective, and quick to install.

[0064] Of course, in other embodiments, the shape of the main shell of the male connector 5 can be constructed as a circle, and three magnetic members arranged in an equilateral triangle can be provided on the side of the male connector 5 facing the female connector 4 on the same side, and one of the three magnetic members has opposite magnetic properties to the other two. In this way, the male connector 5 can be guided to automatically rotate to the appropriate position, thereby achieving a fool-proof effect.

[0065] In addition, the magnetic component assembly on the female connector 4 on the same side can also be relocated in the slot, and the magnetic component assembly on the male connector 5 can be relocated on the side wall of the male connector 5 .

[0066] Of course, other structures can also be used to achieve foolproofing and connection functions.

[0067] For example, a snap-on structure can be used instead of magnetic attraction. The snap-on structure can achieve both positioning and fixation. Specifically, a protruding hook is integrally injection-molded on the male connector 5, and a socket is provided on the side of the female connector 4 on the same side facing the male connector 5. A hook groove is formed on one side of the hook, and a protruding hook that snaps into the hook groove is injection-molded in the socket. The insertion end of the hook tapers to provide a guide. The advantage of this snap-on structure is that it not only achieves a stable connection but also prevents reverse insertion. Furthermore, the outer shape of the inner end of the male connector 5 is rectangular, and the cross-section of the second slot is also rectangular, which can further prompt the operator to indicate the insertion direction. Alternatively, two rectangular columns can be provided on the male connector 5 at the same time as the hook, with the length directions of the two rectangular columns perpendicular to each other. At the same time, holes are provided in the second connector that are oriented in a manner that matches the two rectangular columns. This can also further prevent reverse insertion. When the rectangular column protrudes from the hook, the operator can have a sense of reverse insertion in advance and can make timely adjustments.

[0068] For another example, a card slot and a card block with a unique orientation are provided between the female connector 4 and the male connector 5 on the same side, and the female connector 4 on the same side can only be inserted along this one orientation.

[0069] For another example, an asymmetric plug-in block is provided on the male connector 5 to be plugged into the jack of the female connector 4 on the same side.

[0070] For another example, a guide groove and a guide protrusion with a unique orientation are provided between the side wall of the male connector 5 and the inner wall of the second slot, and the male connector 5 can only be inserted along this one orientation. Figure 3 The guide protrusion is a prism 12, which is provided on the side wall of the male connector 5. It can ensure that the electrical connection between the male connector 5 and the second slot and the male connector 5 and the female connector 4 on the same side are accurately aligned. At this time, the shape of the main shell of the female connector 4 on the same side can be relatively simple, such as cylindrical.

[0071] For another example, a plurality of asymmetric guide protrusions are provided on the side wall of the male connector 5 to be plugged into the plurality of guide grooves on the side wall of the second slot, or a plurality of asymmetric guide protrusions are provided on the inner end of the male connector 5 to be plugged into the plurality of jacks on the same side of the female connector 4.

[0072] For another example, a rod is provided on the end face of the male connector 5 facing the female connector 4 on the same side, and a socket is provided on the female connector 4 on the same side. The rod is inserted into the socket, and the end of the rod has a through hole extending perpendicularly to the direction of extension of the rod. The end of the socket in the female connector 4 on the same side has a locking rod supported by a spring. When the rod is inserted into the socket, the locking rod enters the through hole, locking the male connector 5 and the female connector 4 on the same side. At this time, the rod and the socket also constitute a guide structure. This connection structure itself has an audible feedback when it is in place, for example, the "click" sound formed by the locking rod hitting the wall of the socket. Alternatively, the connection structure can also be provided with a protrusion on the male connector 5 and a groove on the side wall of the second slot. The protrusion and the groove cooperate to form a snap connection, and a "click" sound is emitted when it is in place.

[0073] Thus, the guide and anti-reverse insertion structure can be composed of two independent structures or just one structure. If the guide and anti-reverse insertion structure is a single structure, it can be set on the female connector 4 on the same side or in the second slot. If the guide and anti-reverse insertion structure is two structures, it can be set on one of the female connector 4 and the second slot on the same side, or it can be set in the female connector 4 and the second slot on the same side.

[0074] For another example, the main body shell of the male connector 5 is constructed in a single directional shape, such as a trapezoidal, crescent-shaped, arc-shaped, etc., which can only be inserted in one direction. In this way, other guiding structures can be omitted, and only a simple connection structure (such as a magnetic connection) can be used for connection.

[0075] Furthermore, in this embodiment, mutually attracting magnetic elements are provided between the male connector 5 and the opposite female connector 3, thereby enhancing the stability of the connection. Preferably, the male connector 5 is provided with two magnetic elements 9 that attract the magnetic elements in the opposite female connector 3. Furthermore, preferably, the magnetic elements in this embodiment are all rectangular magnets.

[0076] Therefore, in this embodiment, magnetic connections are used between the opposite-side female connector 3 and the male connector 5, and between the same-side female connector 4 and the male connector 5. This design is based on the fact that when the adapter 1 and handle 2 are plugged in, the opposite-side female connector 3, the male connector 5, and the same-side female connector 4 are confined to two slots, and simple magnetic fixation is sufficient. However, for a more stable connection, the connection structure between the opposite-side female connector 3 and the male connector 5, and between the same-side female connector 4 and the male connector 5 can be modified to a locking structure, such as a snap-fit connection (hereinafter referred to as a locking connection structure).

[0077] Of course, the above structure is generally applicable to situations where the insertion orientation of the male connector 5 is fixed, such as when the electrical connection structure arrays on the inner and outer sides of the male connector 5 are different. However, in another embodiment, when the male connector 5 is symmetrically arranged inside and outside and front and back, and the position and structure of the conductive connectors on both sides are exactly the same, it is sufficient to only appropriately match the shape of the main body of the male connector 5 with the shape of the second slot, and to use a magnetic connection or other connection structure.

[0078] Furthermore, since the opposite-side female connector 3, the same-side female connector 4, and the male connector 5 are all configured to be replaceable in this embodiment, the following design is made to facilitate the removal of the opposite-side female connector 3, the same-side female connector 4, and the male connector 5:

[0079] The outer notch of the first slot is inclined to the periphery to be spaced apart from the outer side wall of the opposite female connector 3 . The outer side wall of the opposite female connector 3 forms an annular groove to facilitate manual removal of the opposite female connector 3 .

[0080] The outer notch of the second slot is inclined in all directions to be spaced apart from the outer side wall of the male connector 5. An annular groove 8 is formed on the outer side wall of the female connector 4 on the same side, and an annular groove 11 is formed on the outer side wall of the male connector 5 to facilitate manual removal of the female connector 4 and the male connector 5 on the same side.

[0081] The annular groove involved is an annular shape formed continuously along the circumference of the side wall of the main body, and the cross-section of the groove can be semicircular or rectangular.

[0082] In summary, because communication between the adapter 1 and the handle 2 requires a male and female connector, the male connector 5 is easily damaged by repeated insertion and removal between the adapter 1 and the handle 2. Since the adapter 1 is less expensive than the handle 2, the prior art places the male connector 5 in the handle 2. Once damaged, the handle 2 must be replaced. In contrast, the present invention utilizes a transitional, detachable male connector 5 to achieve communication between the adapter 1 and the handle 2. Because the male connector 5 can be replaced separately if damaged, plugging the male connector 5 into either the handle 2 or the adapter 1 does not affect replacement costs.

[0083] When the male connector 5 is mounted on the handle 2, the female connector on the adapter 1 remains unchanged, and the male connector 5 can have a mechanical and communication connection structure that matches the original female connector. When the male connector 5 is mounted on the adapter 1, the female connector on the handle 2 remains unchanged, and the male connector 5 can have a mechanical and communication connection structure that matches the original female connector. The female connector in the same slot as the male connector 5 can only have structural innovations on the side that connects to the male connector 5; the structures on other sides can maintain the design of the male connector 5 in the prior art.

[0084] The clip applier in the surgical instrument is selected as a reference above, and the actuator that cooperates with the handle is the adapter 1. However, the present invention is not limited thereto, and can also be applied to surgical instruments including a handle, such as hemostats, staplers, etc.

[0085] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may alter, modify, replace and modify the above embodiments within the scope of the present invention.
