Cross-reference to related applications

[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 519,450, filed August 14, 2023, entitled “Adapters For Surgical Impacting Tools,” which is incorporated herein by reference in its entirety. Technical Field

[0002] This disclosure relates in its entirety to adapters for surgical impact tools. Background Technology

[0003] In the field of orthopedic surgery, prosthetic devices such as artificial joints are typically implanted or placed in a patient's bone cavity. The cavity is usually formed during surgery, and the prosthetic device is placed or implanted by removing and / or compressing existing bone to create the cavity, for example, by a physician or other medical professional. Prosthetic devices (also referred to as prostheses) typically include rods or other protrusions inserted into the cavity.

[0004] To create a cavity, a physician or other medical professional may use a drill, chisel, or other surgical instrument shaped like a rod conforming to the prosthetic device. Generally, the surgical instrument is pushed into the implantation area to form a cavity. One technique for pushing the surgical instrument involves a physician or other medical professional manually striking a surgical impact tool to push the instrument into the implantation area. Another technique for creating a prosthetic cavity relies on a computer-controlled robotic arm to create the cavity, rather than using manual power provided by a physician or other medical professional. Yet another technique for creating a prosthetic cavity is, for example, pneumatically actuating the surgical instrument using compressed air. Another technique for creating a prosthetic cavity relies on a linear compressor to compress air on a single-stroke basis, and then, after sufficient pressure has been generated, release the air through a valve onto an impactor to push the surgical instrument.

[0005] Drills, chisels, or other surgical instruments can be removably attached to surgical impact tools to, for example, allow the use of surgical instruments of different sizes and / or shapes with surgical impact tools in different surgical procedures to help adapt to the needs of a particular patient, allow the replacement of worn, damaged, or otherwise undesirable surgical instruments without having to replace the remainder of the surgical impact tool, and / or adapt to the surgeon's personal preference for surgical instruments. However, various techniques for creating prosthetic cavities by actuating surgical instruments (such as the four techniques discussed above) may loosen the removable connection between the surgical instrument and the surgical impact tool due to the force required to actuate the surgical instrument. Such loosening can cause the surgical instrument to inadvertently detach from the surgical impact tool during the surgical procedure, can cause the surgical instrument to wobble in an unintentional direction or otherwise move, and thus cause patient injury and / or adversely affect cavity formation, and / or can hinder cavity formation by not allowing the surgical instrument to be received and actuated with the fully intended force.

[0006] Therefore, improved surgical impact tools are still needed. Summary of the Invention

[0007] Generally speaking, adapters for surgical impact tools and methods for using the adapters for surgical impact tools are provided.

[0008] In one aspect, a surgical device is provided. In one embodiment, the surgical device includes a first adapter and a second adapter. The first adapter is configured to extend distally from a surgical impact tool handle configured to drive impact against bone. The first adapter is configured to be releasably attached to the surgical impact tool handle and includes a first mating feature configured to be releasably coupled to a first mating element of a first surgical instrument configured to impact bone. The second adapter is configured to extend distally from the surgical impact tool handle. Only one of the first and second adapters is configured to extend distally from the surgical impact tool handle at a time. The second adapter is configured to be releasably attached to the surgical impact tool handle and includes a second mating feature configured to be releasably coupled to a second mating element of a second surgical instrument configured to impact bone, and the second mating feature is different from the first mating feature.

[0009] Surgical systems can vary in many ways. For example, the second mating feature can have a different geometry than the first mating feature.

[0010] For example, the first mating feature may be configured to cooperate with the first mating element to prevent rotation of the first surgical instrument relative to the first adapter when the first surgical instrument is releasably attached to the first adapter. In some embodiments, the first mating feature may include a distally facing cavity having a cross pin extending across the diameter of the cavity. In some embodiments, the first mating feature may include a distally extending protrusion configured to be disposed in a proximally facing cavity of the first surgical instrument, the protrusion having a cross-sectional shape that may be D-shaped, oval, Z-shaped, rectangular, star-shaped, hexagonal, or octagonal, and the proximally facing cavity may have a corresponding cross-sectional shape. Furthermore, the protrusion may extend from a surface of the first adapter where no cavity is formed; and / or the second mating feature may be configured to cooperate with the second mating element to prevent rotation of the second surgical instrument relative to the second adapter when the second surgical instrument is releasably attached to the second adapter. The second mating feature may include a distally extending second protrusion configured to be disposed in a proximal cavity of the second surgical instrument, and the second protrusion may have a cross-sectional shape different from that of the protrusion of the first adapter. In some embodiments, the first mating feature may include a distally extending cavity configured to receive the proximally extending protrusion of the first surgical instrument therein. The cross-sectional shape of the distally extending cavity may be one of D-shape, oval, Z-shape, rectangular, star-shaped, hexagonal, or octagonal, and the protrusion may have a corresponding cross-sectional shape. Furthermore, the distally facing cavity may be formed in the distally extending surface of the first adapter without any protrusions extending therefrom; the second mating feature may be configured to cooperate with the second mating element to prevent rotation of the second surgical instrument relative to the second adapter when the second surgical instrument is releasably attached to the second adapter, the second mating feature may include a second distally facing cavity configured to receive a proximally extending protrusion of the second surgical instrument therein, and the second distally facing cavity may have a cross-sectional shape different from the cross-sectional shape of the distally facing cavity of the first adapter; and / or the second mating feature may be configured to cooperate with the second mating element to prevent rotation of the second surgical instrument relative to the second adapter when the second surgical instrument is releasably attached to the second adapter.

[0011] For example, the first mating feature may be one of the following: a distally facing cavity having a transverse pin extending across the diameter of the cavity; a distally extending protrusion configured to be disposed in a proximally facing cavity of the first surgical instrument and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangular shape, star shape, hexagonal shape, or octagonal shape; and a distally facing cavity configured to receive the proximally extending protrusion of the first surgical instrument therein and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangular shape, star shape, hexagonal shape, or octagonal shape.

[0012] For example, the first adapter may further include a first pivotable arm configured to pivot into engagement with a first surgical instrument releasably coupled to the first adapter, and the second adapter may further include a second pivotable arm configured to pivot into engagement with a second surgical instrument releasably coupled to the second adapter. Furthermore, the first pivotable arm may include one of: (1) a textured surface configured to engage with the surface of the first surgical instrument to improve retention of the first adapter to the first surgical instrument; and (2) a magnet configured to magnetically attract to the first surgical instrument to improve retention of the first adapter to the first surgical instrument; and the second pivotable arm may include one of: (1) a textured surface configured to engage with the surface of the second surgical instrument to improve retention of the second adapter to the second surgical instrument; and (2) a magnet configured to magnetically attract to the second surgical instrument to improve retention of the second adapter to the second surgical instrument.

[0013] Alternatively, only one of the first adapter and the second adapter may include a pivotable arm configured to pivot into engagement with a surgical instrument releasably coupled to one of the first adapter and the second adapter, and the second adapter may also include a second pivotable arm configured to pivot into engagement with a second surgical instrument releasably coupled to the second adapter. Furthermore, one of the first adapter and the second adapter may include one of: (1) a textured surface configured to engage the surface of the surgical instrument to improve retention of one of the first adapter and the second adapter to the surgical instrument; and (2) a magnet configured to magnetically attract to the surgical instrument to improve retention of one of the first adapter and the second adapter to the surgical instrument.

[0014] For example, the first mating feature may be integrally formed with the first adapter, and the second mating feature may be integrally formed with the second adapter or configured to be releasably attached to the second adapter.

[0015] Alternatively, the first mating feature may be configured to be releasably attached to the first adapter, and the second mating feature may be integrally formed with or configured to be releasably attached to the second adapter.

[0016] For example, the proximal portion of the first adapter or the proximal portion of the second adapter may be configured to be received within the surgical impact tool handle, with the first mating feature located on the distal surface of the first adapter and the second mating feature located on the distal surface of the second adapter.

[0017] For example, the surgical system may include a surgical impact tool handpiece. Furthermore, the surgical system may include a first surgical instrument and a second surgical instrument; and / or the surgical impact tool handpiece may include a distally facing cavity configured to receive a first portion of a first adapter or a second portion of a second adapter therein, a first mating feature may be located on the distally facing surface of the first adapter, and a second mating feature may be located on the distally facing surface of the second adapter.

[0018] Alternatively, the surgical system may include a third adapter configured to extend distally from the surgical impact tool handle. Only one of the first, second, and third adapters may be configured to extend distally from the surgical impact tool handle at a time. The third adapter may be configured to be releasably attached to the surgical impact tool handle. The third adapter may include a third mating feature configured to be releasably coupled to a third mating element of a second surgical instrument configured to impact bone, and the third mating feature may be different from the first and second mating features. Furthermore, the surgical system may include a surgical impact tool handle. Additionally, the surgical system may include a first surgical instrument, a second surgical instrument, and a third surgical instrument.

[0019] In another embodiment, a surgical system includes a surgical impact tool handle configured to drive an impact against bone, and an adapter configured to extend distally from the surgical impact tool handle. The adapter includes a mating feature configured to releasably engage with a mating element of a surgical instrument configured to impact bone. The mating feature is configured to cooperate with the mating element to prevent rotation of the surgical instrument relative to the adapter when the surgical instrument is releasably attached to the adapter. The mating feature is one of the following: a distally facing cavity having a transverse pin extending across the diameter of the cavity; a distally extending protrusion configured to be placed in a proximally facing cavity of a surgical instrument and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangle, star shape, hexagon, or octagon; and a distally facing cavity configured to receive the proximally extending protrusion of the surgical instrument therein and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangle, star shape, hexagon, or octagon.

[0020] The system can have any number of variations. For example, the mating feature can be configured to cooperate with the mating element to prevent the surgical instrument from rotating relative to the adapter when the surgical instrument is releasably attached to the adapter.

[0021] For example, the mating feature can be integrally formed with the adapter.

[0022] For example, the mating feature can be configured to be releasably attached to the adapter.

[0023] Alternatively, the proximal portion of the adapter can be configured to be received within the surgical impact tool handle, and the mating feature can be located on the distal surface of the first adapter.

[0024] For example, the surgical system may include surgical instruments.

[0025] Alternatively, the adapter can be configured to be releasably attached to the surgical impact tool handpiece. Furthermore, the surgical system may include at least one additional adapter, each of which may be configured to be releasably attached to the surgical impact tool handpiece such that one of the primary adapter and the at least one additional adapter is configured to extend distally from the surgical impact tool handpiece. Each of the at least one additional adapter may include a second mating feature configured to be releasably coupled to a second mating element of a second surgical instrument configured to impact bone, and the second mating feature may be configured to cooperate with the second mating element to prevent rotation of the second surgical instrument relative to the additional adapter when the second surgical instrument is releasably attached to the second adapter.

[0026] For example, the adapter can be non-releasably attached to the handpiece of a surgical impact tool.

[0027] In another embodiment, a surgical system includes a first adapter and a second adapter. The first adapter is configured to extend distally from a surgical impact tool handle configured to drive an impact against bone. The second adapter is configured to extend distally from the first adapter. The first adapter includes a first mating feature configured to releasably engage with a second mating element of the second adapter. The first mating feature is one of: a distally facing cavity having a transverse pin extending across the diameter of the cavity; a distally extending protrusion configured to be disposed within a proximally facing cavity of a surgical instrument and having a cross-sectional shape of one of D-shape, oval, Z-shape, rectangular, star-shaped, hexagonal, or octagonal; and a distally facing cavity configured to receive therein the proximally extending protrusion of the surgical instrument and having a cross-sectional shape of one of D-shape, oval, Z-shape, rectangular, star-shaped, hexagonal, or octagonal.

[0028] The system can have any number of variations. For example, the second adapter can be non-releasably attached to a surgical instrument configured to impact bone.

[0029] For example, a surgical system may include a surgical instrument configured to impact bone, and a second adapter may be configured to be releasably coupled to the surgical instrument.

[0030] For example, a surgical system may include a surgical instrument configured to impact bone, and a first mating feature of a first adapter may be configured to be releasably coupled to one of the surgical instrument and a second adapter.

[0031] Alternatively, the first mating feature may be configured to cooperate with the second mating element to releasably engage the first mating feature with the second mating element to prevent the second adapter from rotating relative to the first adapter.

[0032] For example, the first mating feature can be integrally formed with the first adapter, and the second mating element can be integrally formed with the second adapter.

[0033] Alternatively, the first mating feature may be configured to be releasably attached to the first adapter.

[0034] For example, the proximal portion of the first adapter may be configured to be received within the surgical impact tool handle, and the first mating feature may be located on the distal surface of the first adapter.

[0035] Alternatively, the first adapter can be configured to be releasably attached to the surgical impact tool handpiece.

[0036] For example, the first adapter can be non-releasably attached to the surgical impact tool handpiece.

[0037] For example, a surgical system may include a handheld component for a surgical impact tool.

[0038] In another aspect, a surgical method is provided, in one embodiment of which includes: releasably attaching one of a first adapter or a second adapter to a surgical instrument; and, with one of the first adapters or the second adapter releasably attached to the surgical instrument, causing the surgical instrument to impact relative to bone. The first adapter is configured to extend distally from a surgical impact tool handle configured to drive the impact against bone. The first adapter is releasably attached to the surgical impact tool handle and includes a first mating feature configured to releasably engage with a first mating element of a first surgical instrument configured to impact bone. The second adapter is configured to extend distally from the surgical impact tool handle. Only one of the first and second adapters is configured to extend distally from the surgical impact tool handle at a time. The second adapter is configured to be releasably attached to the surgical impact tool handpiece. The second adapter includes a second mating feature configured to be releasably coupled to a second mating element of a second surgical instrument configured to impact bone, and the second mating feature is different from the first mating feature.

[0039] The method can have any number of variations. For example, the method may also include releasably attaching one of a first adapter or a second adapter to the surgical impact tool handpiece prior to the impact of the surgical instrument.

[0040] In another embodiment, a surgical method includes: releasably attaching an adapter to a surgical instrument; and, with the adapter releasably attached to the surgical instrument, impacting the surgical instrument relative to bone. The adapter is configured to extend distally from a surgical impact tool handle. The adapter includes a mating feature configured to releasably engage with a mating element of the surgical instrument configured to impact bone. The mating feature is configured to cooperate with the mating element to prevent rotation of the surgical instrument relative to the adapter when the surgical instrument is releasably attached to the adapter. The mating feature is one of the following: a distally facing cavity having a transverse pin extending across the diameter of the cavity; a distally extending protrusion configured to be placed in a proximally facing cavity of a surgical instrument and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangle, star shape, hexagon, or octagon; and a distally facing cavity configured to receive the proximally extending protrusion of the surgical instrument therein and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangle, star shape, hexagon, or octagon.

[0041] This method can be varied in several ways. For example, the method may include releasably attaching an adapter to the surgical impact tool handpiece prior to the impact of the surgical instrument.

[0042] For example, the adapter can be non-releasably attached to the handpiece of a surgical impact tool.

[0043] In another embodiment, a surgical method includes releasably coupling a first mating feature of a first adapter to a second mating element of a second adapter. The method further includes, when the first mating feature of the first adapter is releasably coupled to the second mating element of the second adapter, and when a surgical instrument extends distally from the second adapter, impacting the surgical instrument relative to bone. The first adapter is configured to extend distally from a surgical impact tool handle configured to drive the impact against bone. The second adapter is configured to extend distally from the first adapter. The first mating feature is one of the following: a distally facing cavity having a transverse pin extending across the diameter of the cavity; a distally extending protrusion configured to be placed in a proximally facing cavity of a surgical instrument and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangular shape, star shape, hexagonal shape, or octagonal shape; and a distally facing cavity configured to receive the proximally extending protrusion of the surgical instrument therein and having a cross-sectional shape of one of D-shape, oval shape, Z-shape, rectangular shape, star shape, hexagonal shape, or octagonal shape.

[0044] This method can be varied in several ways. For example, the second adapter can be non-releasably attached to a surgical instrument.

[0045] For example, the method may include releasably connecting a second mating feature of the second adapter to a third mating element of the surgical instrument. Attached Figure Description

[0069] Certain exemplary embodiments will now be described to provide an overall understanding of the structure, function, manufacture, and principles of use of the apparatuses, systems, and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the apparatuses, systems, and methods specifically described herein and illustrated in the drawings are non-limiting exemplary embodiments, and that the scope of the invention is defined only by the claims. Features illustrated or described in conjunction with one exemplary embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be included within the scope of the invention.

[0070] Those skilled in the art will recognize that equivalent dimensions for such linear and circular dimensions can be readily determined for any geometry. They will also understand that dimensions may not be precise values, but are considered approximately within that value due to any number of factors such as manufacturing tolerances and the sensitivity of the measuring equipment (e.g., within + / - 0.5% of that value). The dimensions and shapes of systems and devices, and their components, can depend at least on the dimensions and shapes of the components to be used with the systems and devices.

[0071] Various exemplary adapters for surgical impact tools and methods of using the adapters for surgical impact tools are provided. Generally, the adapter can be configured to be releasably attached to a surgical instrument configured to impact bone. The adapter can be fixedly, non-releasably attached to a surgical impact tool handle, or can be configured to be releasably attached to a surgical impact tool handle. The surgical impact tool handle, such as the handle of an orthopedic impactor, is configured to drive the impact of the surgical instrument relative to bone. The surgical impact tool handle attached to the adapter is configured to provide force to the surgical instrument via the adapter to drive the impact of the surgical instrument. The surgical instrument configured to be attached to the adapter can be a drill, bone chisel, or other surgical instrument. Furthermore, each of a plurality of surgical instruments configured to be attached to the adapter can differ from each other in one or more aspects (such as shape, size, etc.), thereby allowing a surgeon (or other medical professional) to select a particular surgical instrument to achieve the optimal desired impact in a particular surgical procedure performed on the bone of a particular patient.

[0072] Different surgical instruments and different adapters can have different mating geometries. If the mating geometries of the surgical instrument and the adapter do not correspond to each other, the surgical instrument and the adapter cannot be connected together. More specifically, different surgical instruments can have different mating elements that are configured to be releasably connected to the mating features of the adapter. Therefore, some surgical instruments may only be usable with certain adapters, and thus only with certain surgical impact tool handles. Different adapters having different mating features configured to be releasably connected to surgical instruments allow surgical impact tool handles to be releasably connected to a variety of different surgical instruments with different mating elements.

[0073] Surgical impact tool handles are typically more expensive than surgical instruments, for example, due to their complex design and / or the inclusion of electronic components (e.g., motors, processors, etc.) in surgical instruments that do not. Therefore, surgical impact tool handles, which can be selectively attached to a variety of different surgical instruments via adapters that are releasably or non-releasably attached to the handle, can provide a cost-effective option for hospitals, medical personnel, etc., as it is possible to purchase a single, more expensive surgical impact tool handle for use with a variety of cheaper surgical instruments, rather than purchasing multiple surgical impact tool handles, each limited to use with certain surgical instruments having certain mating elements.

[0074] Surgical instruments can be single-use items, constructed for use only in a single surgical procedure performed on a single patient. In this case, surgical impact tool handles capable of selectively attaching to various different surgical instruments could allow for the reuse of more expensive surgical impact tool handles in different surgical procedures performed on different patients.

[0075] Surgical instruments (whether or not they are designed for single use) can wear down over time due to their impact on bone and require disposal as waste. In this case, surgical impact tool handles that can be selectively attached to a variety of different surgical instruments can allow more expensive surgical impact tool handles to be reused, even if the surgical instruments previously used with the surgical impact tool handle have been disposed of as waste.

[0076] In some surgical procedures, surgeons or other medical personnel may determine that a second surgical instrument should be used on a patient, rather than selecting a first surgical instrument for a particular patient. A first and second surgical instrument, each configured to be releasably coupled to the same surgical impact tool handpiece, can allow one surgical impact tool handpiece to be available in the operating room (OR) and easily switch from being coupled to the first surgical instrument to being coupled to the second surgical instrument, thereby saving time and / or costs during the execution of the surgical procedure by requiring only one surgical impact tool handpiece in the OR.

[0077] As described above, the adapter can be configured to be releasably attached to the surgical impact tool handpiece. The ability to releasably attach the adapter to the surgical impact tool handpiece allows the surgical impact tool handpiece to be releasably attached to a variety of different adapters. Each adapter can differ from one another in one or more aspects (such as length, mating features configured for releasable attachment to the surgical instrument, etc.), thereby allowing the surgeon (or other medical professional) to select a particular adapter to achieve the optimal desired impact in a specific surgical procedure performed on the bone of a particular patient.

[0078] As described above, the adapter can be non-releasably attached to the surgical impact tool handpiece. In some embodiments, the adapter non-releasably attached to the surgical impact tool handpiece is configured to be releasably attached to a variety of different intermediate adapters. Each of the intermediate adapters is either non-releasably attached to or configured to be releasably attached to a surgical instrument. Each of the intermediate adapters may differ from one another in one or more aspects (such as length, mating features configured to releasably engage with a surgical instrument, etc.), thereby allowing the surgeon (or other medical professional) to select a particular intermediate adapter to achieve the optimal desired impact in a specific surgical procedure performed on the bone of a particular patient.

[0079] In some embodiments, a kit includes a surgical impact tool handpiece and multiple adapters, each adapter configured to be releasably attached to the surgical impact tool handpiece and each adapter including a different mating feature. Thus, the surgical impact tool handpiece can be configured to be releasably coupled to various surgical instruments with different mating elements. Furthermore, the kit may include multiple surgical instruments, each having a different mating element corresponding to a different mating feature of the adapter. Therefore, the resulting tool assembly (which can be assembled as needed according to user selection) may include a three-part chain structure comprising the surgical impact tool handpiece, one of the multiple adapters, and one of the multiple surgical instruments.

[0080] In some embodiments, a kit includes a surgical impact tool handpiece and a plurality of adapters. One or more of the plurality of adapters (a first number of adapters) are configured to be releasably coupled to the surgical impact tool handpiece. The remaining adapters (a second number of adapters) are configured to be releasably coupled to at least one of the first number of adapters, and each adapter includes a different mating feature. The first and second numbers of the plurality of adapters may be the same as each other, for example, the first number and the second number may each be 1, 2, 3, 4, 5, or greater than 5. Alternatively, the first and second numbers of the plurality of adapters may be different from each other, for example, the first number is 1 and the second number is 2, 3, 4, 5, or greater than 5; the first number is 2, 3, 4, 5, or greater than 5 and the second number is 1; or the first number is 2, 3, 4, 5, or greater than 5 and the second number is different from 2, 3, 4, 5, or greater than 5. Furthermore, the kit may include a plurality of surgical instruments, each having a different mating element corresponding to a different mating feature of the second number of adapters. Therefore, the resulting tool assembly (which can be assembled on demand according to the user's selection) may include a 4-part chain structure, which includes a surgical impact tool handpiece, one of a first number of adapters, one of a second number of adapters, and one of a plurality of surgical instruments.

[0081] In some embodiments, a kit includes a surgical impact tool handpiece and a plurality of adapters. One or more adapters (a first number of adapters) are configured to be releasably coupled to the surgical impact tool handpiece, and each adapter includes a different mating feature. The remaining adapters (a second number of adapters) are configured to be releasably coupled to at least one of the first number of adapters, each adapter having a different mating element corresponding to the different mating features of the first number of adapters, and each adapter is non-releasably attached to the surgical instrument. The first and second numbers of adapters may be the same as each other, for example, the first number and the second number are each 1, 2, 3, 4, 5, or greater than 5. Alternatively, the first and second numbers of adapters may be different from each other, for example, the first number is 1 and the second number is 2, 3, 4, 5, or greater than 5; the first number is 2, 3, 4, 5, or greater than 5 and the second number is 1; or the first number is 2, 3, 4, 5, or greater than 5 and the second number is different from those among 2, 3, 4, 5, or greater than 5. Therefore, the resulting tool assembly (which can be assembled on demand according to the user's selection) may include a 3-part chain structure, which includes a surgical impact tool handpiece, one of a first number of adapters, and one of a second number of adapters (which has an integral surgical instrument).

[0082] In some embodiments, a kit includes a surgical impact tool handpiece having an adapter non-releasably attached thereto. The kit also includes a plurality of surgical instruments, each configured to be releasably attached to the adapter. Each of the surgical instruments has a mating element corresponding to a mating feature of the adapter, allowing selective engagement of the surgical instrument to the adapter. The surgical impact tool handpiece can thus be configured to be releasably engaged with a variety of different surgical instruments. Therefore, the resulting tool assembly (which can be assembled as needed according to user selection) can include a two-part chain structure comprising the surgical impact tool handpiece (with an integral adapter) and one of the plurality of surgical instruments.

[0083] In some embodiments, a kit includes a surgical impact tool handpiece having an adapter non-releasably attached thereto. The kit also includes a plurality of intermediate adapters and a plurality of surgical instruments, each surgical instrument configured to be releasably attached to at least one of the intermediate adapters. Each surgical instrument has a mating element corresponding to a mating feature of at least one of the intermediate adapters, allowing the surgical instrument to be selectively coupled to the adapter via the intermediate adapter. The surgical impact tool handpiece can therefore be configured to be releasably coupled to a variety of different surgical instruments. Thus, the resulting tool assembly (which can be assembled as needed according to user selection) can include a three-part chain structure comprising the surgical impact tool handpiece (having an integral adapter), one of the intermediate adapters, and one of the surgical instruments.

[0084] In some implementations, a tool assembly may include more than two adapters. For example, a tool assembly may include a chain structure of four or more components, the chain structure including a surgical impact tool handle, at least three adapters, and a surgical instrument releasably or non-releasably attached to at least three adapters (e.g., attached to the most distal adapter of at least three adapters).

[0085] Figures 1 to 3 An embodiment of a surgical impact tool handpiece 100 is illustrated. In this illustrated embodiment, the handpiece is a handpiece for an orthopedic impactor, but as described above, the surgical impact tool can be another type of surgical impact tool. The handpiece 100 includes a locking assembly configured to be releasably attached to an adapter. The locking assembly is located at a front or distal end 102 of the surgical impact tool handpiece 100, the front or distal end having a distally facing cavity 114 formed therein. Various exemplary embodiments of the locking assembly are further described in, for example, U.S. Patent Publication No. 2022 / 0361934 entitled “Surgical Impinging Tool Interfaces”, published November 17, 2022, and U.S. Patent Publication No. 2024 / 0156503 entitled “Surgical Impinging Tool Couplings”, published May 16, 2024, respectively, the entire contents of which are incorporated herein by reference. Embodiments of the adapter are further discussed below.

[0086] In this illustrated embodiment, the surgical impact tool handpiece 100 is configured to be releasably attached to the adapter. In other embodiments, the surgical impact tool handpiece 100 may be non-releasably attached to the adapter.

[0087] The adapter (whether releasably attached to the surgical impact tool handpiece 100 or non-releasably attached to the surgical impact tool handpiece 100) can be configured to be releasably directly coupled to the surgical instrument, or can be configured to be releasably indirectly coupled to the surgical instrument via one or more intermediate adapters.

[0088] The surgical impact tool handpiece 100 includes an actuator 104 configured to be actuated to drive a surgical instrument attached to an adapter releasably attached to the handpiece 100 via a locking component. In this exemplary embodiment, the actuator 104 includes a trigger located on a handle 106 of the handpiece 100, but other surgical impact tools may be actuated in other ways. In an exemplary embodiment, the handpiece 100 is configured to provide forward and backward impacts, wherein in a forward impact, the handpiece 100 provides a forward force for impact in a forward direction, and in a backward impact, the handpiece 100 provides a backward force for impact in a backward direction. The forward and backward impacts may be cyclical, with the forward and backward impacts being repeated sequentially. In some embodiments, the handpiece 100 may be configured to provide only one of the forward and backward impacts.

[0089] The power source 108 is configured to be releasably attached to the handle 106 of the handheld device 100. In this illustrated embodiment, the power source 108 includes a battery, but other power sources are also possible. In other embodiments, the handheld device 100 may be releasably attached to the power source in another manner, such as by insertion into the power source. In other embodiments, the power source may be non-releasably attached to the handheld device 100, such as by a battery non-removably disposed, for example, in the handle 106.

[0090] The handheld component 100 includes an energy selector 110 on a handle 106 of the handheld component 100. In this exemplary embodiment, the energy selector 110 includes a rotary dial, but may have other configurations, such as a lever, a button, etc. The energy selector 110 is configured to allow selection of an energy level, such as high energy or low energy.

[0091] The handheld device 100 includes a frequency control 112 on the handle 106 of the handheld device 100. In this illustrated embodiment, the frequency controller 112 includes a button, but may have other configurations, such as a lever, a rotary dial, etc. The frequency controller 112 is configured to allow the user to select the frequency of the impact, such as a slow impact or a fast impact.

[0092] The handpiece 100 may have additional or alternative features. Various exemplary embodiments of surgical impact tool handpieces, including additional or alternative features, are further described in, for example, U.S. Patent Publication No. 2022 / 0361934, entitled "Surgical Impacting Tool Interfaces," published November 17, 2022; U.S. Patent Publication No. 2013 / 0161050, entitled "Electric Motor Driven Tool For Orthopedic Impacting," published June 27, 2013; U.S. Patent No. 10,912,597, entitled "Orthopedic Adapter For An Electric Impacting Tool," published February 9, 2021; U.S. Patent No. 11,083,512, entitled "Orthopedic Impacting Device Delivering A Controlled, Repeatable Impact," published August 10, 2021; and U.S. Patent No. 11,083,512, entitled "Orthopedic Impacting Device Having A Launched Mass Delivering A Controlled, Repeatable & Reversible Impacting," published October 5, 2021. The following U.S. patents are incorporated herein by reference in their entirety: U.S. Patent No. 11,134,962 entitled “Electric Motor Driven Tool For Orthopedic Impacting”, U.S. Patent No. 8,393,409 entitled “Electric Motor Driven Tool For Orthopedic Impacting”, published March 12, 2013; U.S. Patent No. 8,936,105 entitled “Electric Motor Driven Tool For Orthopedic Impacting”, published January 20, 2015; and U.S. Patent No. 8,695,726 entitled “Electric Motor Driven Tool For Orthopedic Impacting”, published April 15, 2014.

[0093] Figures 4 to 8 Another embodiment of a surgical impact tool handpiece 200 is illustrated, which is configured to be releasably attached to an adapter 300. Figures 4 to 8An adapter 300 is shown that is releasably attached to a handheld component 200 via a locking assembly, wherein the proximal portion of the adapter 300 is disposed in a distally facing cavity formed in the handheld component 200. Figures 4 to 8 (The obstruction is in the middle). The implementation of the adapter 300 is further discussed below. In this illustrated implementation, the handpiece 200 is a handpiece of an orthopedic impactor, but as mentioned above, the surgical impact tool can be another type of surgical impact tool. The handpiece 200 is typically associated with... Figure 1 The handheld component 100 is similarly constructed and used, for example, including a locking assembly located at the front or distal end 202 of the handheld component 200, and including an actuator 204, a handle 206, an energy selector 210 (a lever in this illustrated embodiment), and a frequency controller 212 (a dial in this illustrated embodiment). In this illustrated embodiment, the handheld component 200 is constructed at its bottom end 208 for releasable attachment to a power source, similar to how the handheld component 100 is releasably attached to the power source 108 as described above.

[0094] In this illustrated embodiment, the surgical impact tool handle 200 is configured to be releasably attached to the adapter 300. In other embodiments, the surgical impact tool handle 200 may be non-releasably attached to the adapter 300.

[0095] The adapter 300 (whether releasably attached to the surgical impact tool handpiece 200 or non-releasably attached to the surgical impact tool handpiece 200) can be configured to be releasably directly coupled to the surgical instrument, or can be configured to be releasably indirectly coupled to the surgical instrument via one or more intermediate adapters.

[0096] The adapter 300 and other embodiments of the adapter described herein may be formed of a rigid biocompatible material, such as stainless steel, titanium, or other materials. Rigid biocompatible materials allow the adapter to withstand repeated impacts without deformation or breakage during the performance of one or more surgical procedures and while in use with one or more surgical impact tool handles.

[0097] Figure 9 Another embodiment of the adapter 400 is illustrated, which is configured to releasably attach to a surgical impact tool handpiece, such as... Figures 1 to 3 Surgical impact tool handpiece 100 Figures 4 to 8 The surgical impact tool handpiece 200 or another surgical impact tool handpiece. In other embodiments, the adapter 400 may be non-releasably attached to the surgical impact tool handpiece.

[0098] The adapter 400 (whether releasably or non-releasably attached to the surgical impact tool handpiece) can be configured to be releasably directly coupled to the surgical instrument, or can be configured to be releasably indirectly coupled to the surgical instrument via one or more intermediate adapters. Figure 20 and Figure 21 An embodiment of the surgical instrument 1000 is illustrated, which, as discussed further below, is configured to be releasably attached to Figure 9 Adapter 400. Figure 22 An embodiment of intermediate adapter 1100 is illustrated, as discussed further below, wherein the intermediate adapter is configured to be releasably attached to Figure 9 Adapter 400.

[0099] Adapter 400 includes a proximal portion 400p, a distal portion 400d, and an intermediate portion 400i located between the proximal portion 400p and the distal portion 400d. The distal portion 400d of adapter 400 is configured to be releasably attached to a surgical instrument or another adapter configured to be releasably (directly or indirectly) attached to the surgical instrument. The proximal portion 400p of adapter 400 is configured to be releasably attached to (or fixedly attached to) a surgical impact tool handle.

[0100] In this illustrated embodiment, the proximal portion 400p of the adapter 400 has a substantially cylindrical shape and a substantially circular cross-sectional shape. Those skilled in the art will understand that the shape may not be precise, for example, not precisely cylindrical or precisely circular (e.g., within + / - 0.5% of the diameter of a cylinder and a circle), but is still considered substantially that shape due to any number of factors such as manufacturing tolerances and the sensitivity of the measuring device. The substantially cylindrical shape and substantially circular cross-sectional shape of the proximal portion 400p can reduce the angular clearance of the adapter 400 relative to the surgical impact tool handle, which is at least partially disposed within, for example, within a distally facing cavity formed in the handle. The smaller angular clearance between the adapter and the surgical impact tool handle in which the adapter is partially disposed can allow for a more robust fit between the adapter and the handle, and / or can facilitate more precise impacts along the longitudinal axis of the adapter, and thus provide a more predictable, bone-directed impact because the angular movement of the adapter relative to the longitudinal axis is reduced. In other embodiments, the proximal portion 400p of the adapter 400 may have different shapes and cross-sectional shapes. Similarly, the substantially cylindrical shape and substantially circular cross-sectional shape of the proximal portion 400p may reduce the angular clearance of the adapter 400 relative to the intermediate adapter, the proximal portion 400p being at least partially disposed within the intermediate adapter, for example, disposed within a distally facing cavity formed in the intermediate adapter.

[0101] In this illustrated embodiment, adapter 400 includes a body 402, a proximal pivotable arm 404, and a distal pivotable arm 406. In some embodiments, the proximal pivotable arm 404 and / or the distal pivotable arm 406 may be omitted.

[0102] A first pivot pin 408 is pivotally connected to a proximal pivotable arm 404 of a body 402. The proximal pivotable arm 404 is configured to pivot relative to the body 402 at the first pivot pin 408. The proximal pivotable arm 404 is configured to dynamically pivot relative to the body 402 during connection of the adapter 400 with a surgical impact tool handpiece (e.g., during insertion of the proximal portion 400p into the surgical impact tool handpiece). A surface 404a of the proximal pivotable arm 404 is configured to contact a surface of the surgical impact tool handpiece to aid in stabilizing the adapter 400 relative to the surgical impact tool handpiece.

[0103] A second pivot pin 410 pivotally connects a distal pivotable arm 406 to a body 402. The distal pivotable arm 406 includes an elongated portion 406a and a snap-fit ​​member 406b pivotally connected to the elongated portion 406a via a third pivot pin 412. The distal pivotable arm 406 is configured to pivot relative to the body 402 at the second pivot pin 410. The snap-fit ​​member 406b of the distal pivotable arm 406 is configured to pivot relative to the elongated portion 406a of the distal pivotable arm 406 at the third pivot pin 412. The elongated portion 406a of the distal pivotable arm 406 is configured to pivot dynamically relative to the body 402, and the snap-fit ​​member 406b of the distal pivotable arm 406 is configured to pivot dynamically relative to the elongated portion 406a of the distal pivotable arm 406 during connection of the adapter 400 with a surgical instrument or intermediate adapter. The surface 406c of the snap-fit ​​component 406b is configured to contact the surface of the surgical instrument or intermediate adapter to help stabilize the adapter 400 relative to the surgical instrument or intermediate adapter.

[0104] The surface 406c of the snap-fit ​​component may include a retaining feature configured to improve retention of the surgical instrument to the adapter 400. Various retaining features are possible. For example, in some embodiments, the retaining feature may include a textured surface, such as raised bumps, crosshairs, etc. In other embodiments, the retaining feature may include at least one magnet configured to magnetically attract the surgical instrument.

[0105] Other embodiments of the adapters discussed herein that include snap-fit ​​components may include retaining features.

[0106] As described above, the distal portion 400d of the adapter 400 is configured to be releasably connected to a surgical instrument or intermediate adapter. Therefore, the adapter 400 can be connected (directly or indirectly) to any of a variety of surgical instruments, thereby increasing the versatility of the adapter 400.

[0107] In this illustrated embodiment, the distal portion 400d of the adapter 400 has a rectangular dome cross-sectional shape and a shape similar to a conventional mailbox. In other embodiments, the distal portion 400d of the adapter 400 may have different shapes and cross-sectional shapes.

[0108] In this illustrated embodiment, the distal portion 400d of the adapter 400 is an integral part of the body 402. In other embodiments, the distal portion 400d may be a separate component configured to be releasably attached to the remainder of the body 402. The releasable attachment of the distal portion 400d allows the adapter 400 to be used with existing surgical impact tool handles that would otherwise be incompatible with surgical instruments having mating elements configured to releasably engage with mating features of the distal portion.

[0109] Other implementations of the adapter discussed herein may include those that are not releasable from the body or are configured to be releasably coupled to a distal portion of the body.

[0110] The adapter 400 includes a mating feature in a distal portion 400d configured to mate with a mating element of a surgical instrument or intermediate adapter. The mating feature is located on the distal side of the adapter 400 and is therefore distally oriented. In this illustrated embodiment, the mating feature includes a cavity 414a formed in the adapter 400 (its body 402) and a protrusion (also referred to herein as a “bore”) 414b formed on the adapter 400 (its body 402) and extending distally. In this illustrated embodiment, the cavity 414a has a substantially cylindrical shape and a substantially circular cross-sectional shape. Those skilled in the art will understand that the shape may not be precise, for example, not precisely cylindrical or precisely circular (e.g., within + / - 0.5% of the diameter of a cylinder or circle), but is still considered substantially that shape due to any number of factors such as manufacturing tolerances and the sensitivity of the measuring device. Other shapes of the cavity 414a are possible, such as box-shaped, pyramidal, hemispherical, etc. In this illustrated embodiment, the protrusion 414b has a substantially cylindrical shape and a substantially circular cross-sectional shape. Other shapes of the protrusion 414b are possible, such as box-shaped, pyramid-shaped, hemispherical, etc.

[0111] The mating feature is configured to cooperate with a mating element of a surgical instrument or intermediate adapter, the mating element having a geometry corresponding to the geometry of the mating feature. In this way, only surgical instruments or intermediate adapters whose mating element geometry corresponds to the geometry of the mating feature of the adapter can mate with the adapter. In this illustrated embodiment, the mating feature cavity 414a is configured to receive a corresponding proximal protrusion of the surgical instrument or intermediate adapter, i.e., a protrusion having a substantially cylindrical shape and a substantially circular cross-sectional shape, and the mating feature boss 414b is configured to be received in a corresponding distal cavity of the surgical instrument or intermediate adapter, i.e., a cavity having a substantially cylindrical shape and a substantially circular cross-sectional shape.

[0112] As in this illustrated embodiment, the mating feature of adapter 400 can be configured as an anti-rotation feature to prevent rotation of a surgical instrument or intermediate adapter relative to adapter 400, wherein the surgical instrument or intermediate adapter mats with adapter 400. Preventing rotation of the surgical instrument or intermediate adapter relative to adapter 400 can provide stable, predictable placement impact. In this illustrated embodiment, the mating feature cavity 414a and the mating feature protrusion 414b are configured to cooperate in preventing rotation of the surgical instrument or intermediate adapter relative to adapter 400, because when the surgical instrument or intermediate adapter mats with both the mating feature cavity 414a and the mating feature protrusion 414b, the surgical instrument or intermediate adapter cannot rotate relative to adapter 400.

[0113] Figure 10 Another embodiment of the adapter is illustrated, which is configured to releasably attach to the handpiece of a surgical impact tool, such as... Figures 1 to 3 Surgical impact tool handpiece 100 Figures 4 to 8 Surgical impact tool handpiece 200, or another surgical impact tool handpiece. Figure 10 The adapter and the one mentioned above Figure 9 The adapter 400 discussed is similarly constructed and used, for example, including a proximal portion, a distal portion, an intermediate portion located between the proximal and distal portions, a body 502, a proximal pivoting arm (not shown), and a distal pivoting arm (not shown). In some embodiments, the proximal pivoting arm and / or the distal pivoting arm may be omitted.

[0114] In addition to matching the feature section Figure 10 The adapter body 502 is related to the above. Figure 9 The adapter body 402 discussed is constructed and used in a similar manner. Figure 10 The mating feature is located on the distal side of the adapter and therefore faces the distal side, but in Figure 10 In the illustrated embodiment, the mating feature includes a cavity 514a formed in the adapter (its body 502) and has a cross pin 514b extending diameter across the cavity 514a. In this illustrated embodiment, the cavity 514a has a substantially cylindrical shape and a substantially circular cross-sectional shape, but other shapes are also possible. In this illustrated embodiment, the cross pin 514b has a substantially cylindrical shape and a substantially circular cross-sectional shape, but other shapes are also possible.

[0115] The mating features are configured to work with surgical instruments (e.g., Figure 20 and Figure 21 Surgical instruments 1000 or other surgical instruments) or intermediate adapters (e.g., Figure 22 The intermediate adapter 1100 or other adapter mates with a mating element having a geometry corresponding to the geometry of the mating feature. In this way, only surgical instruments or intermediate adapters whose mating element geometry corresponds to the geometry of the mating feature of the adapter can mate with the adapter. In this illustrated embodiment, the mating feature cavity 514a is configured to receive a corresponding proximal protrusion of the surgical instrument or intermediate adapter therein. The proximal protrusion may include a pair of protrusions configured to be received in the cavity 514a, wherein the first protrusion is received on a first side of a transverse pin 514b in a first half of the cavity 514a, and the second protrusion is received on a second side of a transverse pin 514b in a second half of the cavity 514a.

[0116] Figure 10 The mating feature of the adapter is configured as an anti-rotation feature to prevent rotation of the surgical instrument or intermediate adapter relative to the adapter, wherein the surgical instrument or intermediate adapter is mated to the adapter. The mating feature cavity 514a, due to its cylindrical shape, cannot alone prevent rotation of the surgical instrument or intermediate adapter relative to the adapter. The mating feature cross pin 514b is configured to prevent rotation of the surgical instrument or intermediate adapter relative to the adapter because, when the surgical instrument or intermediate adapter is mated to both the mating feature cavity 514a and the mating feature cross pin 514b, the surgical instrument or intermediate adapter cannot rotate relative to the adapter.

[0117] In this illustrated embodiment, the distally facing surface of the adapter in which the mating feature cavity 514a is formed has no protrusions extending distally from the distally facing surface, and no other cavities are formed in the distally facing surface. Therefore, Figure 10 The mating feature is a single mating feature, unlike a mating feature with multiple elements on the distal surface (such as...). Figure 9 Compared to a mating feature that includes a cavity 414a formed in the distal surface and a protrusion 414b extending from the distal surface, this mating feature can simplify manufacturing and / or simplify the releasable connection of surgical instruments or intermediate adapters with adapters.

[0118] exist Figure 10 In this exemplary embodiment, the adapter is configured to be releasably attached to the surgical impact tool handpiece. In other embodiments, the adapter may be non-releasably attached to the surgical impact tool handpiece.

[0119] Figure 11 Another embodiment of the adapter is illustrated, which is configured to releasably attach to the handpiece of a surgical impact tool, such as... Figures 1 to 3 Surgical impact tool handpiece 100 Figures 4 to 8 Surgical impact tool handpiece 200, or another surgical impact tool handpiece. Figure 11 The adapter and the one mentioned above Figure 9 The adapter 400 discussed is similarly constructed and used, for example, including a proximal portion, a distal portion, an intermediate portion located between the proximal and distal portions, a body 602, a proximal pivoting arm (not shown), and a distal pivoting arm (not shown). In some embodiments, the proximal pivoting arm and / or the distal pivoting arm may be omitted.

[0120] In addition to matching the feature section Figure 11 The adapter body 602 is related to the above. Figure 9 The adapter body 402 discussed is constructed and used in a similar manner. Figure 11 The mating feature 614 is located on the distal side of the adapter and is therefore facing the distal side, but in Figure 11 In the illustrated embodiment, the mating feature 614 includes a cavity formed in the adapter (its body 602). In this illustrated embodiment, the cavity 614 has a substantially hexagonal shape and a substantially hexagonal cross-sectional shape.

[0121] The mating features are configured to work with surgical instruments (e.g., Figure 20 and Figure 21 Surgical instruments 1000 or other surgical instruments) or intermediate adapters (e.g., Figure 22The intermediate adapter 1100 or other adapter mates with a mating element having a geometry corresponding to the geometry of the mating feature. In this way, only surgical instruments or intermediate adapters whose mating element geometry corresponds to the geometry of the mating feature of the adapter can mate with the adapter. In this illustrated embodiment, the mating feature cavity 614 is configured to receive a corresponding proximal protrusion of the surgical instrument or intermediate adapter having a substantially hexagonal cross-sectional shape.

[0122] Figure 11 The mating feature 614 of the adapter is configured as an anti-rotation feature to prevent the surgical instrument or intermediate adapter from rotating relative to the adapter, wherein the surgical instrument or intermediate adapter mats with the adapter. Figure 9 and Figure 10 The mating feature cavities 414a and 514a are different. The mating feature cavity 614 is constructed independently to prevent the surgical instrument or intermediate adapter from rotating relative to the adapter due to its hexagonal shape.

[0123] In this illustrated embodiment, the distally facing surface of the adapter in which the mating feature cavity 614 is formed has no protrusions extending distally from the distally facing surface, and no other cavities are formed in the distally facing surface. Therefore, Figure 11 The mating feature 614 is a single mating feature, unlike mating features that have multiple elements on the distal surface (such as...). Figure 9 Compared to a mating feature that includes a cavity 414a formed in the distal surface and a protrusion 414b extending from the distal surface, this mating feature can simplify manufacturing and / or simplify the releasable connection of surgical instruments or intermediate adapters with adapters.

[0124] Figure 11 The adapter is configured to connect to a surgical instrument or intermediate adapter in multiple predetermined angular orientations. The surgical instrument or intermediate adapter, connected to and thus operably connected to the surgical impact tool handpiece via the adapter, can therefore be attached to the surgical impact tool handpiece in multiple predetermined angular orientations relative to the surgical impact tool handpiece. Depending on one or more factors such as the surgeon's preference, which hand (left or right) the user is holding the surgical impact tool, which bone the surgical instrument will impact on the patient, and the patient's position relative to the user of the surgical impact tool, one angular orientation of the surgical instrument or intermediate adapter may be more desirable than another.

[0125] The multiple sides (particularly their flat surfaces) that define the shape of the mating feature cavity 614 define multiple predetermined angular orientations. Therefore, in the illustrated embodiment, the adapter is configured to be releasably attached to a surgical instrument or intermediate adapter relative to a handpiece at six predetermined angular orientations: approximately zero degrees, approximately sixty degrees, approximately one hundred and twenty degrees, approximately one hundred and eighty degrees, and approximately two hundred and forty degrees. Thus, in this illustrated embodiment, each of the predetermined angular orientations is spaced approximately sixty degrees from each other.

[0126] Other examples of the shape of the mating feature cavity 614 (which is configured as an anti-rotation feature and defines a plurality of predetermined angular orientations, to which a surgical instrument or intermediate adapter can be releasably connected in the adapter) include an N-sided polygon, where N is an integer of two or greater, such as an equilateral triangle, square, rectangle, pentagon, octagon, star, Z-shape, D-shape, hourglass shape, etc. Another example of the shape of the mating feature cavity 614 (which is configured as an anti-rotation feature and defines a plurality of predetermined angular orientations, to which a surgical instrument or intermediate adapter can be releasably connected in the adapter) includes an elliptical shape defining two predetermined angular orientations.

[0127] In some embodiments, instead of defining multiple predetermined angular orientations (in which a surgical instrument or intermediate adapter can be releasably coupled to the adapter), the mating feature cavity 614 may define a single predetermined angular orientation (in which a surgical instrument or intermediate adapter can be releasably coupled to the adapter). Examples of the shape of the mating feature cavity 614 (which is configured as an anti-rotation feature and defines a single predetermined angular orientation in which a surgical instrument or intermediate adapter can be releasably coupled to the adapter) include isosceles triangles, irregular polygonal shapes (e.g., pear shapes, non-convex pentagons, etc.).

[0128] exist Figure 11 In this exemplary embodiment, the adapter is configured to be releasably attached to the surgical impact tool handpiece. In other embodiments, the adapter may be non-releasably attached to the surgical impact tool handpiece.

[0129] Figure 12 Another embodiment of the adapter is illustrated, which is configured to releasably attach to the handpiece of a surgical impact tool, such as... Figures 1 to 3 Surgical impact tool handpiece 100 Figures 4 to 8 Surgical impact tool handpiece 200, or another surgical impact tool handpiece. Figure 12 The adapter and the one mentioned above Figure 9The adapter 400 discussed is similarly constructed and used, for example, including a proximal portion, a distal portion, an intermediate portion located between the proximal and distal portions, a body 702, a proximal pivoting arm (not shown), and a distal pivoting arm (not shown). In some embodiments, the proximal pivoting arm and / or the distal pivoting arm may be omitted.

[0130] In addition to matching the feature section Figure 12 The adapter body 702 is related to the above. Figure 9 The adapter body 402 discussed is constructed and used in a similar manner. Figure 12 The mating feature 714 is located on the distal side of the adapter and is therefore facing the distal side, but in Figure 12 In the illustrated embodiment, the mating feature 714 includes a boss formed on the adapter (its body 702). In this illustrated embodiment, the boss 714 has a substantially triangular prism shape and a substantially equilateral triangular cross-sectional shape.

[0131] The mating features are configured to work with surgical instruments (e.g., Figure 20 and Figure 21 Surgical instruments 1000 or other surgical instruments) or intermediate adapters (e.g., Figure 22 The intermediate adapter 1100 or other adapter mates with a mating element having a geometry corresponding to the geometry of the mating feature. In this way, only surgical instruments or intermediate adapters whose mating element geometry corresponds to the geometry of the mating feature of the adapter can mate with the adapter. In this illustrated embodiment, the mating feature protrusion 714 is configured to be received in a corresponding cavity of the surgical instrument or intermediate adapter, the cavity having a substantially triangular prism shape and a substantially triangular cross-sectional shape.

[0132] Figure 12 The mating feature 714 of the adapter is configured as an anti-rotation feature to prevent the surgical instrument or intermediate adapter from rotating relative to the adapter, wherein the surgical instrument or intermediate adapter mats with the adapter. Figure 9 Unlike the mating feature protrusion 414b, the mating feature protrusion 714 is independently constructed to prevent the surgical instrument or intermediate adapter from rotating relative to the adapter due to its triangular shape.

[0133] In this illustrated embodiment, the distal surface of the adapter on which the mating feature protrusion 714 is formed has no other protrusions extending distally from the distal surface, and no cavities are formed in the distal surface. Therefore, Figure 12 The mating feature 714 is a single mating feature.

[0134] Figure 12 The adapter is configured to be attached to a surgical instrument or intermediate adapter in multiple predetermined angular orientations. The surgical instrument or intermediate adapter, attached to and thus operably attached to the surgical impact tool handle via the adapter, can therefore be attached to the surgical impact tool handle relative to the surgical impact tool handle in multiple predetermined angular orientations. Multiple sides (particularly its flat surfaces) defining the shape of the mating feature protrusion 714 define multiple predetermined angular orientations. Thus, in the illustrated embodiment, the adapter is configured to be releasably attached to the surgical instrument relative to the handle in three predetermined angular orientations: approximately zero degrees, approximately 120 degrees, and approximately 240 degrees. Therefore, in this illustrated embodiment, each of the predetermined angular orientations is spaced approximately 120 degrees from each other.

[0135] Other examples of the shape of the mating feature protrusion 714 (which is configured as an anti-rotation feature and defines a plurality of predetermined angular orientations, in which a surgical instrument can be releasably connected to the adapter) include an N-sided polygon, where N is an integer of two or greater, such as a square, rectangle, pentagon, octagon, star, Z-shape, D-shape, hourglass shape, etc. Another example of the shape of the mating feature protrusion 714 (which is configured as an anti-rotation feature and defines a plurality of predetermined angular orientations, in which a surgical instrument or intermediate adapter can be releasably connected to the adapter) includes an elliptical shape defining two predetermined angular orientations.

[0136] In some embodiments, instead of defining multiple predetermined angular orientations (in which a surgical instrument or intermediate adapter can be releasably coupled to the adapter), the mating feature protrusion 714 may define a single predetermined angular orientation (in which a surgical instrument or intermediate adapter can be releasably coupled to the adapter). Examples of the shape of the mating feature protrusion 714 (which is configured as an anti-rotation feature and defines a single predetermined angular orientation in which a surgical instrument or intermediate adapter can be releasably coupled to the adapter) include isosceles triangles, irregular polygonal shapes (e.g., pear shapes, non-convex pentagons, etc.).

[0137] exist Figure 12 In this exemplary embodiment, the adapter is configured to be releasably attached to the surgical impact tool handpiece. In other embodiments, the adapter may be non-releasably attached to the surgical impact tool handpiece.

[0138] Figure 13 Another embodiment of the adapter 800 is illustrated, which is configured to releasably attach to a surgical impact tool handpiece, such as... Figures 1 to 3Surgical impact tool handpiece 100 Figures 4 to 8 Surgical impact tool handpiece 200 or another surgical impact tool handpiece. Figure 13 The adapter 800 and the above-mentioned Figure 9 The adapter 400 discussed is similarly constructed and used, for example, including a proximal portion, a distal portion, an intermediate portion located between the proximal and distal portions, a body 802, and a proximal pivotable arm 804 pivotally connected to the body 802 by means of a first pivot pin 808. Figure 13 (Partially shown) A distal pivotable arm (including an elongated portion 806a and a snap-fit ​​member 806b pivotally connected to the elongated portion 806a via a second pivot pin 810) pivotally connected to the body 800, and a mating feature including a cavity 814a formed in the adapter 802 (its body 802) and a protrusion 814b formed on the adapter 800 (its body 802) and extending distally. In some embodiments, the proximal pivotable arm and / or the distal pivotable arm may be omitted.

[0139] In addition to the distal pivot arm Figure 12 The adapter 800 and the above-mentioned Figure 9 The adapter 400 is similarly constructed and used as discussed. In this illustrated embodiment, the latching member 806b of the distal pivotable arm 806 is not configured to dynamically pivot relative to the elongated portion 806a of the distal pivotable arm 806 during connection of the adapter 800 to a surgical instrument or intermediate adapter or at another time. Instead, the pivoting of the latching member 806b of the distal pivotable arm 806 relative to the elongated portion 806a of the distal pivotable arm 806 is configured to be manually controlled. This manual control of the pivoting of the latching member allows for a more secure holding of the surgical instrument connected to the adapter 800.

[0140] The adapter 800 includes a drive mechanism 816 configured to drive manual pivoting of the snap-fit ​​member 806b. In this illustrated embodiment, the drive mechanism 816 includes a threaded rod fixedly attached to the snap-fit ​​member 806b and threadedly engaged with the threads of the body 802. Manually rotating the drive mechanism 816 (directly by hand or indirectly using a separate tool) is configured to cause the drive mechanism 816 to translate longitudinally proximally or distally, as indicated by arrow A. Whether the drive mechanism 816 moves proximally or distally depends on the direction of rotation of the drive mechanism relative to the body 802. The longitudinal translation of the drive mechanism 816 is configured to pivot the snap-fit ​​member 806b relative to the elongated portion 806a of the distal pivotable arm 806, thereby pivoting away from or distally in response to distal movement of the drive mechanism 816, and pivoting toward or proximally in response to proximal movement of the drive mechanism 816.

[0141] The snap-fit ​​components of other embodiments of the adapters discussed herein, which include snap-fit ​​components, may be configured to be manually controlled (e.g., manually controlled using a drive mechanism) rather than dynamically pivoting.

[0142] In this illustrated embodiment, adapter 800 is configured to be releasably attached to the surgical impact tool handpiece. In other embodiments, adapter 800 may be non-releasably attached to the surgical impact tool handpiece.

[0143] Figures 14 to 19 Another embodiment of the adapter 900 is illustrated, which is configured to releasably attach to a surgical impact tool handpiece, such as... Figures 1 to 3 Surgical impact tool handpiece 100 Figures 4 to 8 Surgical impact tool handpiece 200, or another surgical impact tool handpiece. Figures 14 to 19 The adapter 900 and the above-mentioned Figure 9 The adapter 400 discussed is similarly constructed and used, for example, including a proximal portion, a distal portion, an intermediate portion located between the proximal and distal portions, a body 902, and a mating feature including a cavity 914a formed in the adapter 900 (its body 902) and a protrusion 914b formed on the adapter 900 (its body 902) and extending distally. However, the adapter 900 and Figure 9 The adapter 400 differs in that the adapter 900 does not include a proximal or distal pivoting arm, and the distal portion is enlarged and includes a curved portion at the distal end of the adapter 900. The adapter 900 is configured for impacting the hip bone. The curved portion of the adapter 900 facilitates the entry of surgical instruments releasably (directly or indirectly) coupled to the distal end of the adapter 900 into the hip bone.

[0144] Other embodiments of the adapter discussed herein may include a distal portion that is enlarged and includes a curved portion located at the distal end of the adapter, similar to adapter 900.

[0145] In this illustrated embodiment, the adapter 900 is configured to be releasably attached to the surgical impact tool handpiece. In other embodiments, the adapter 900 may be non-releasably attached to the surgical impact tool handpiece.

[0146] As described above, various surgical instruments such as bone chisels and drills can be configured to be releasably attached to adapters, such as Figure 3 and Figures 5 to 8 Adapter 300 Figure 9 Adapter 400 Figure 22Adapter 1100 Figure 10 adapter, Figure 11 adapter, Figure 12 adapter, Figure 13 Adapter 800 Figures 14 to 19 Adapter 900, or another adapter. Figure 20 and Figure 21 An embodiment of a surgical instrument 1000 configured to be releasably attached to an adapter is illustrated. In this illustrated embodiment, the surgical instrument 1000 is a hip drill configured for impacting the hip bone. The surgical instrument 1000 includes a mating element configured to releasably engage with a mating feature of the adapter. In this illustrated embodiment, the mating element includes a protrusion 1002a and a cavity 1002b. The protrusion 1002a extends proximally and is configured to be received in a corresponding mating feature cavity of the adapter. The protrusion 1002a has a varying cross-sectional shape along its length, but other shapes are possible, similar to those discussed above regarding the mating features. The cavity 1002b is formed in the proximal side of the surgical instrument 1000 and is configured to receive the corresponding mating feature protrusion of the adapter therein. The cavity 1002b has a U-shaped cross-sectional shape, but other shapes are possible, similar to those discussed above regarding the mating features.

[0147] As described above, the alternative surgical instrument is releasably attached to the adapter (such as a surgical instrument) by means of a mating feature that releasably engages with the adapter to extend distally from the adapter. Figure 3 and Figures 5 to 8 Adapter 300 Figure 9 Adapter 400 Figure 22 Adapter 1100 Figure 10 adapter, Figure 11 adapter, Figure 12 adapter, Figure 13 Adapter 800 Figures 14 to 19 The second adapter (or another adapter) can be releasably attached to the adapter by engaging with a mating feature of the adapter to extend distally from the adapter. The second adapter can increase the versatility of the adapter connected to it. Also as described above, the linked adapter chain structure can include two adapters or more than two adapters, such as three, four, etc.

[0148] Figure 22 An embodiment of a second adapter 1100 is illustrated, which is configured to be releasably attached to another adapter, referred to herein as the "first adapter" for ease of explanation. Figure 22 The adapter 1100 and the above-mentioned Figure 9The adapter 400 discussed is similarly constructed and used, for example, including a proximal portion, a distal portion and an intermediate portion located between the proximal portion and the distal portion, as well as a body. Figure 22 The adapter 1100 does not include a proximal pivoting arm or a distal pivoting arm. However, in other embodiments, the second adapter may include a proximal pivoting arm and / or a distal pivoting arm.

[0149] The second adapter 1100 includes a mating element configured to releasably engage with a mating feature of the first adapter. Figure 22 An example is shown where the second adapter 1100 is configured to be releasably attached to Figure 9 The adapter 400 serves as the first adapter. However, other second adapters can be constructed and used similarly to the second adapter 1100 to be releasably attached to other embodiments of the adapter described herein, for example, via mating elements having mating features adapted to engage with a particular adapter. Additionally, the second adapter 1100 can be releasably attached to other... Figure 9 The first adapter other than adapter 400.

[0150] In this illustrated embodiment, the mating element of the second adapter 1100 includes a protrusion 1102 and a cavity (in Figure 22 (The portion is obscured). The protrusion 1102 extends proximally and is configured to be received in a corresponding mating feature cavity of the adapter, which in this illustrated embodiment is cavity 414a of the first adapter 400. A cavity is formed in the proximal side of the second adapter 1100 and is configured to receive a corresponding mating feature protrusion therein, which in this illustrated embodiment is protrusion 414b of the first adapter 400. Therefore, in this illustrated embodiment, the mating element protrusion 1102 of the second adapter 1100 has a substantially cylindrical shape and a substantially circular cross-sectional shape, but other shapes and cross-sectional shapes are also possible as discussed herein. Therefore, in this illustrated embodiment, the mating element cavity of the second adapter 1100 has a substantially cylindrical shape and a substantially circular cross-sectional shape, but other shapes and cross-sectional shapes are also possible as discussed herein.

[0151] The second adapter 1100 includes a mating feature configured to releasably mate with a mating element of a surgical instrument or with a mating element of another (third) adapter. The mating feature of the second adapter 1100 is located on the distal side of the second adapter 1100 and is therefore distally oriented. Figure 22In the illustrated embodiment, the mating feature includes a cavity 1104a formed in the second adapter 1100 (its body) and a protrusion 1104b extending distally from the distal side of the second adapter 1100. In this illustrated embodiment, the mating feature cavity 1104a has a substantially rectangular shape and a substantially rectangular cross-sectional shape, but other shapes and cross-sectional shapes are possible as discussed herein. In this illustrated embodiment, the mating feature protrusion 1104b has a substantially rectangular shape and a substantially rectangular cross-sectional shape, but other shapes and cross-sectional shapes are possible as discussed herein. Additionally, in this illustrated embodiment, the mating feature cavity 1104a is located above the mating feature protrusion 1104b, but the mating feature cavity 1104a and the mating feature protrusion 1104b can be arranged in other ways.

[0152] The mating feature of the second adapter 1100 is configured to mate with a mating element of a surgical instrument or intermediate adapter, the mating element having a geometry corresponding to the geometry of the mating feature. In this way, only surgical instruments or intermediate adapters whose mating element geometry corresponds to the geometry of the mating feature of the adapter can mate with the second adapter 1100. In this illustrated embodiment, the mating feature cavity 1104a is configured to receive a corresponding proximal protrusion of the surgical instrument or intermediate adapter having a substantially rectangular cross-sectional shape, and the mating feature protrusion 1104b is configured to be received in a corresponding proximal cavity of the surgical instrument or intermediate adapter having a substantially rectangular cross-sectional shape.

[0153] Figure 22 The mating feature of the second adapter 1100 is configured as an anti-rotation feature to prevent rotation of the surgical instrument or intermediate adapter relative to the second adapter 1100, wherein the surgical instrument or intermediate adapter is mated to the second adapter 1100. In this illustrated embodiment, the mating feature cavity 1104a and the mating feature protrusion 1104b are configured to cooperate in preventing rotation of the surgical instrument or intermediate adapter relative to the second adapter 1100, because when the surgical instrument or intermediate adapter is mated to both the mating feature cavity 1104a and the mating feature protrusion 1104b, the surgical instrument or intermediate adapter cannot rotate relative to the second adapter 1100.

[0154] exist Figure 22In this exemplary embodiment, the second adapter 1100 is configured to be releasably attached to a surgical instrument or another intermediate adapter. In other embodiments, the second adapter 1100 may be non-releasably attached to a surgical instrument. In such embodiments, the second adapter 1100 may not be releasably attached to another intermediate adapter.
