[0002] Among the potential, but non-limiting, objects of the present disclosure are to provide a mounting system for surgical procedure elements, such as, for example, a reamer, that can be easily aligned when the parts are connected together prior to transmitting high levels of primarily torque but also axial loads [compressive and tensile]. Among the potential, but non-limiting, objects of the present disclosure are to provide a mounting system that is rotationally self-aligning. Summary of the Invention [Means for solving the problem]

[0003] According to a first aspect of the present disclosure, there is provided a mounting component for connecting a surgical procedure element to another element, the mounting component comprising: a mount body provided on an end of another element or on an end of a surgical procedure element; the mount body has a first end and a second end, the mount body has a longitudinal axis, the first end being spaced from the second end along the longitudinal axis; the mount body has a first surface profile section, the first surface profile section including a first radial profile taken as perpendicular to the longitudinal axis; the mount body has a second surface profile section, the second surface profile section being closer to the second end of the mount body than the first surface profile section, the second surface profile section including a second radial profile that is perpendicular to the longitudinal axis and that is considered parallel to the first radial profile; The second surface profile section is at least partially defined by one or more alignment elements, and the second radial profile has a different radial profile than the first radial profile surface due to the presence of the one or more alignment elements.

[0004] The mount component may be provided on another element. The other element may be a force application device, such as a power source, or an extension element. In that case, potentially in accordance with a second aspect of the present disclosure, a second mount component may be provided on the surgical procedure element. One or more or all of the surgical procedure elements may be, for example, surgical instruments. The one or more surgical procedure elements may be a reamer and / or a file and / or a broach. The one or more surgical procedure elements may be surgical parts, such as trial parts and / or final parts for a surgical procedure.

[0005] The mount component may be provided on a surgical procedure element, in which case a second mount component may be provided on another element, potentially in accordance with a second aspect of the present disclosure.

[0006] In a first embodiment, the mounting part may be a female part and the second part may be a male part. The female part may be provided on a separate element.

[0007] In a further embodiment, the mounting part may be a male part and the second part may be a female part. The male part may be provided on the surgical procedure element.

[0008] When the mount component is a female component, in a first embodiment, the second surface profile section may have a different radial profile than the first radial profile surface due to the presence of one or more alignment elements, which reduce the second radial profile in portions of the second radial profile where the one or more alignment elements are present. The one or more alignment elements may extend radially inward. The one or more alignment elements may extend radially inward into a bore in the mount body.

[0009] When the mount component is a male component, in further embodiments, the second surface profile section may have a different radial profile than the first radial profile surface due to the presence of one or more alignment elements, the one or more alignment elements increasing the second radial profile in portions of the second radial profile where the one or more alignment elements are present. The one or more alignment elements may extend radially outward. The one or more alignment elements may extend radially outward away from the outer surface of the mount body.

[0010] The mount body may include an outer wall. The outer wall may at least partially surround the internal bore. The outer wall may define an outer surface profile section for the mount body. The outer surface profile section may be at least partially cylindrical. The outer surface profile section may include two or more partially cylindrical profile portions, for example, with an intermediate profile portion therebetween. The outer surface profile section may include two or more planar profile portions. One or more or all of the intermediate profile portions may be provided by planar profile portions. The outer surface profile section may be defined in part by alternating planar profile portions and partially cylindrical profile portions.

[0011] One or more of the outer profile portions, for example one or more or all of the planar profile portions, may provide for application of torque to the mount body during use.

[0012] One or more through openings may be provided in the mount body. For example, a through opening may be provided in one or more of the planar profile portions. One or more through openings may be provided in a third surface of the mount body. One or more portions of the other or another element of the surgical procedure element may be visible through the one or more through openings during use, for example, when the surgical procedure element and the another element are in an engaged state.

[0013] The first end of the mount body may include an opening to a bore in the mount body, and the other of the surgical procedure element or another element may enter the bore through the opening, for example, during a transition of the surgical procedure element and the other element from a separated state to an engaged state.

[0014] The opening may include an increased radial profile, for example at an end-most portion of the opening. The opening may include a chamfered periphery.

[0015] The second end of the mount body may provide a connection of the mount body to the surgical procedure element or another element. The connection may be a bore that receives an end of the surgical procedure element or another element.

[0016] The mount body can have a longitudinal axis that extends through the mount body and into the surgical procedure element or another element. The longitudinal axis can be provided at a first end of the mount body to be aligned with an axis of the bore. The longitudinal axis can be aligned with an axis of movement of the surgical procedure element and the other element relative to one another, for example, when transitioning from a separated state to an engaged state and / or from an engaged state to a separated state.

[0017] The first end of the mount body can be an end limit of both the mount body and the surgical procedure element or another element on which the mount body is provided. The first end of the mount body can be a proximal end when on the surgical procedure element. The first end of the mount body can be a distal end when on the other element.

[0018] The second end of the mount body can be a junction of the mount body with the surgical procedure element or another element on which the mount body is provided. The second end of the mount body can be distal relative to the proximal end when on the surgical procedure element. The second end of the mount body can be proximal relative to the distal end when on the other element.

[0019] The first surface profile section can be provided closer to the first end of the mount body than the second surface profile section, and the third surface profile section can be provided farther from the first end of the mount body than the first surface profile section and / or the second surface profile section, for example.

[0020] The first surface profile section may be present for a section extending from a first end of the mount body to a limit closer to the second end of the mount body. The first surface profile section may be present for a section extending from a limit of an increased radial profile transition section provided at an opening in the first end of the mount body. Thus, the first surface profile section may be present for a section extending from near the first end of the mount body to a limit closer to the second end of the mount body.

[0021] The first surface profile section may have a consistent first radial profile. The first section profile may have a constant extent for the first radial profile. The consistent first radial profile may be a regular shape. The constant extent for the first radial profile may be circular, such as when a circular cross section is provided for a bore in the mount body.

[0022] The first surface profile section may have a consistent first radial profile and / or constant extent throughout the section extending from one axial limit of the first surface profile section to the other axial limit of the first surface profile section. For example, the first section profile may be the section profile of a cylinder, such as a right circular cylinder.

[0023] The first surface profile section can extend from one limit to another limit closer to the second end of the mount body. This other limit can be where a first transition surface is provided. The first transition surface can be provided between the first surface profile section and the second surface profile section.

[0024] The first transition surface may provide a change in radial profile from a first radial profile at least partially towards a second radial profile. The first transition surface may provide a change in radial profile from the first radial profile to the second radial profile for at least one portion of the second surface profile section. The transition to the second radial profile may continue within the second surface profile section for one or more other portions.

[0025] When the first surface profile section is an inner surface, in a first embodiment, the first transition surface may provide an inward increase in at least a portion of the radial profile of the first transition surface when compared to the first radial profile.

[0026] Where the first surface profile section is an outer surface, in further embodiments the first transition surface may provide an outward increase in at least a portion of the radial profile of the first transition surface when compared to the first radial profile.

[0027] The second surface profile section can be positioned intermediate the first profile section and the third surface profile section. The third surface profile section can provide a connection of the mount body to the surgical procedure element or to another element.

[0028] The second radial profile may be defined in part by alignment elements provided at each location about the second surface profile section. The alignment elements may be provided in a regular pattern about the second profile. The alignment elements may be provided, for example, in the same plane that is perpendicular to the longitudinal axis.

[0029] Two or more or all of the alignment elements may be regularly spaced around the second surface profile section and / or may be regularly spaced to provide the second radial profile.

[0030] An intermediate region may be provided between two alignment elements in the second surface profile section. The intermediate region may be a region where the second radial profile differs from the second radial profile in which the alignment element resides. An intermediate region may be provided between each adjacent alignment element in the second surface profile section. The second surface profile section may include a sequence of alternating alignment elements then intermediate regions around the circumference of the second surface profile section.

[0031] The two or more intermediate regions may be regularly spaced around the second surface profile section and / or may be regularly spaced to provide a second radial profile.

[0032] Where the second surface profile section is an interior surface, in the first embodiment, one or more, or all of the alignment elements may provide an inward increase in at least a portion of the radial profile of the second radial profile when compared to the first radial profile. For example, one or more, or all of the alignment elements may extend midway within the bore of the mount body.

[0033] Where the second surface profile section is an outer surface, in further embodiments, one or more, or all of the alignment elements may provide an outward increase in at least a portion of the radial profile of the second radial profile when compared to the first radial profile. For example, one or more, or all of the alignment elements may extend radially from the mount body.

[0034] One or more, or all, of the intermediate regions may have the same radial profile as one another, for example, in one or more given planes perpendicular to the longitudinal axis. One or more, or all, of the intermediate regions may have the same radial profile as one another in all planes. One or more, or all, of the intermediate regions may have the same radial profile as one another in all axial planes or positions. One or more, or all, of the intermediate regions may have a constant cross-sectional profile, for example, in a plane perpendicular to the longitudinal axis.

[0035] One or more, or all, of the alignment elements may have the same radial profile as one another in one or more given planes that are perpendicular to the longitudinal axis, for example. One or more, or all, of the alignment elements may have the same radial profile as one another in all planes. One or more, or all, of the alignment elements may have different radial profiles at two or more different axial positions.

[0036] One or more or all of the alignment elements may have a non-constant cross-sectional profile considered along a first portion of the longitudinal axis, the first portion of the longitudinal axis having a non-constant cross-section may be closer to the first surface profile section than a second portion of the longitudinal axis along which the cross-section is considered.

[0037] The non-constant cross-section along the first portion of the longitudinal axis can define an alignment element transition portion of the second surface profile section. The alignment element transition portion can provide one or more abutment surfaces for the one or more alignment elements. One or more or all of the alignment element transition portions can include a first abutment surface that is angled in one direction and a second abutment surface that is angled in a second direction.

[0038] A sloped transition surface, such as an apex surface, may be provided between a first abutment surface sloped in one direction and a second abutment surface sloped in a second direction. The apex surface may be curved. The apex surface may include an inflection apex line defined by a series of inflection points between the first and second slope directions.

[0039] The first tilt direction and / or the second tilt direction may include a tilt component toward the second end of the mount and / or an axial component along the mount body. The first tilt direction may include a tilt component in one direction about the axis and / or about the mount body with an opposite component to the tilt in the second direction. The first abutment surface may be tilted in a first direction that is a counterclockwise direction about the central axis and / or the second abutment surface may be tilted in a second direction that is a clockwise direction about the central axis.

[0040] The first abutment surface may comprise a further inclination direction, e.g. inwardly with respect to the bore and / or towards the central axis. The further inclination direction may be an inward slope. The second abutment surface may comprise a second further inclination direction, e.g. inwardly with respect to the bore and / or towards the central axis. The second further inclination direction may be an inward slope. The further inclination direction and the second further inclination direction may be the same.

[0041] A first alignment element transition portion, such as a first abutment surface, may be angled at an angle relative to a second alignment element transition portion, such as a second abutment surface. The angle, e.g., the interior angle between, may be 150°±30°, e.g., 150°±20°, e.g., 150°±15°. The angle may be defined between a first alignment element transition portion, e.g., an edge in its middle, and a second alignment element transition portion, e.g., an edge in its middle. The angle may be defined as an interior vertex angle of an intersection of a first alignment element transition portion, such as a first abutment surface, and a second alignment element transition portion, such as a second abutment surface. The intersection may be a projection of a portion of the first alignment element transition portion, such as a portion of the first abutment surface, i.e., a flat surface, and a portion of the second alignment element transition portion, such as a portion of the second abutment surface.

[0042] One or more or all of the alignment element transition portions, such as one or more or all of the abutment surfaces, may be angled at an angle with respect to the longitudinal axis. The angle, e.g., the included angle between, may be 45°±15°, e.g., 45°±10°, e.g., 45°±5°. The angle may be defined between the longitudinal axis and a line extending across the alignment element transition portion, such as the abutment surfaces. The line may extend across the alignment element transition portion from a distal location to a proximal side, in some cases in a direction that provides the shortest distance between the location and the proximal side. The angle may be defined between the longitudinal axis and a line extending across the alignment element transition portion across the apex surface, such as along the inflection of the apex surface.

[0043] One or more of the alignment element transition portions, e.g., one or more or all of the inclined transition surfaces, may be angled at an alternative angle relative to a plane that is perpendicular to the longitudinal axis. The alternative angle may be 15°±10°, e.g., 15°±7°, e.g., 15°±5°.

[0044] One or more or all of the alignment elements may have a constant cross-sectional profile considered along a second portion of the longitudinal axis, the second portion of the longitudinal axis having a constant cross-section may be further from the first surface profile section than a first portion of the longitudinal axis where the cross-section is considered, e.g., varies.

[0045] The constant cross-section along the second portion of the longitudinal axis may, for example, define two or more flat surfaces that transmit torque during use. The constant cross-section along the second portion may provide a cross-section formed of a regular set of flat portions, for example a hexagonal cross-section. The cross-section of the flat portions of the second surface profile section may differ from the circular cross-sectional portions of the first surface profile section.

[0046] The alignment element transition portion can be provided axially prior to a constant cross-sectional profile when transitioning from the disengaged state to the engaged state.

[0047] The mounting component can have a disconnected state in which the surgical component is not connected to another component, and the mounting component can have an engaged state in which the surgical component is connected to another component.

[0048] The mounting components may have a transition state, which may be intermediate between the disengaged state and the engaged state.

[0049] The mount part, e.g. the mount body, may be separated from the second mount part in the separated state. The mount part, e.g. the mount body, may be in contact with the second mount part in the transition state. The mount part, e.g. the mount body, may be in contact with the second mount part in the engaged state. In particular, a flat surface of the second surface profile section may be against and / or in contact with one or more flat surfaces of the second mount part, in particular the second mount part.

[0050] The separation of the longitudinal axes of the mount component and the second mount component may be greater than when in the transition state and / or the engaged state.

[0051] The length of a surgical element within another element, or the length of another element within a surgical element, may be shorter when in the transition state than when in the engaged state. The length of a surgical element within another element, or the length of another element within a surgical element, may be greatest in the engaged state.

[0052] The possible rotational positions about, for example, a longitudinal axis for a surgical element relative to another element, or for another element relative to a surgical element, may not be constrained in the separated state.

[0053] The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, e.g., about a longitudinal axis, may be constrained in the engaged state. A number of distinct rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, may be possible in the engaged state. The distinct rotational positions may be separated from intermediate rotational positions that are not possible. In the distinct rotational positions, movement of the surgical element relative to another element, or movement of the other element relative to the surgical element, may be constrained, e.g., by one or more relative to a mating tolerance. 0 The present invention may be constrained to be less than 100 .mu.m.

[0054] The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, e.g., about a longitudinal axis, may be unconstrained in a first portion of the transition state. The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, e.g., about a longitudinal axis, may be partially constrained in a second portion of the transition state. The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, may be constrained in a third portion of the transition state.

[0055] In the transition state, and particularly in the first portion of the transition state, axial movement of the surgical element and the other element relative to one another may be provided without causing relative rotational movement of the surgical element and the other element relative to one another.

[0056] In the transition state, and particularly in the second portion of the transition state, axial movement of the surgical element and the other element relative to one another may be provided, which induces relative rotational movement of the surgical element and the other element relative to one another. An axial force applied to one of the surgical element and the other element may induce the rotation.

[0057] In the transition state, and particularly in the third portion of the transition state, axial movement of the surgical element and the other element relative to one another may be provided without causing relative rotational movement of the surgical element and the other element relative to one another. An axial force applied to one of the surgical element and the other element may cause only axial movement.

[0058] The transition state may include a first portion of a state, and / or a second portion of the state, and / or a third portion of the state. The mount components may progress from the separated state to the first portion of the transition state and then to the engaged state. The mount components may progress from the separated state to the first portion of the transition state and then to the second portion of the transition state and then to the engaged state. The mount components may progress from the separated state to the first portion of the transition state and then to the second portion of the transition state and then to the third portion of the transition state and then to the engaged state. The order may be reversed when progressing from the engaged state to the separated state.

[0095] The possible rotational positions about, for example, a longitudinal axis for a surgical element relative to another element, or for another element relative to a surgical element, may not be constrained in the separated state.

[0096] The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, e.g., about a longitudinal axis, may be constrained in the engaged state. A number of distinct rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, may be possible in the engaged state. The distinct rotational positions may differ from intermediate rotational positions that are not possible. In the distinct rotational positions, movement of the surgical element relative to another element, or movement of the other element relative to the surgical element, may be constrained, e.g., by one or more relative to a mating tolerance. 0 The present invention may be constrained to be less than 100 .mu.m.

[0097] The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, e.g., about a longitudinal axis, may be unconstrained in a first portion of the transition state. The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, e.g., about a longitudinal axis, may be partially constrained in a second portion of the transition state. The possible rotational positions for a surgical element relative to another element, or for another element relative to a surgical element, may be constrained in a third portion of the transition state.

[0098] In the transition state, and particularly in the first portion of the transition state, axial movement of the surgical element and the other element relative to one another may be provided without causing relative rotational movement of the surgical element and the other element relative to one another.

[0099] In the transition state, and particularly in the second portion of the transition state, axial movement of the surgical element and the other element relative to one another may be provided, which induces relative rotational movement of the surgical element and the other element relative to one another. An axial force applied to one of the surgical element and the other element may induce the rotation.

[0100] In the transition state, and particularly in the third portion of the transition state, axial movement of the surgical element and the other element relative to one another may be provided without causing relative rotational movement of the surgical element and the other element relative to one another. An axial force applied to one of the surgical element and the other element may cause only axial movement.

[0101] The transition state may include a first portion of a state, and / or a second portion of the state, and / or a third portion of the state. The mount components may progress from the separated state to the first portion of the transition state and then to the engaged state. The mount components may progress from the separated state to the first portion of the transition state and then to the second portion of the transition state and then to the engaged state. The mount components may progress from the separated state to the first portion of the transition state and then to the second portion of the transition state and then to the third portion of the transition state and then to the engaged state. The order may be reversed when progressing from the engaged state to the separated state.

[0102] A first portion of the transition state may end when there is an abutment between one or more registration elements and a location on the other of the surgical procedure elements or on another element, which may be an intermediate region of the other of the surgical procedure elements or on another element.

[0103] The second portion of the transition state may begin when there is abutment between one or more alignment elements and a location on the other of the surgical procedure element or on the other element. The second portion of the transition state may include a rotational component to the surgical procedure element and the other element movement. The second portion of the transition state may include an axial movement of the surgical procedure element and the other element movement. The second portion of the transition state may include an axial movement of the surgical procedure element and the other element that is constrained by a rotational component to the movement of the surgical procedure element and the other element. The second portion of the transition state may end when there is no further rotational component to the movement of the surgical procedure element and the other element. The second portion of the transition state may end when further rotational movement of the surgical procedure element and the other element is constrained.

[0104] A second portion of the transition state may include movement of the other location of the surgical element or the location of another element along one or more surfaces of the alignment element, such as their angled surfaces.

[0105] The third portion of the transition state may begin when there is no further rotational component to the movement of the surgical procedure element and the other element. The third portion of the transition state may begin when further rotational movement of the surgical procedure element and the other element is constrained. The third portion of the transition state may include further axial movement of the surgical procedure element and the other element relative to one another. Further axial movement may be possible because the other location of the surgical procedure element or the other element is aligned with a gap through the alignment elements. Further axial movement may be possible because the other location of the surgical procedure element or the other element is aligned with an intermediate region between the alignment elements. The third portion of the transition state may end when further axial movement of the surgical procedure element and the other element is not possible.

[0106] The engaged state may be provided when further axial movement of the surgical element and the other element is not possible. The engaged state may be provided when rotational movement of one of the surgical element and the other element causes rotational movement of the other.

[0107] The engaged state may provide for torque transfer from another element to the surgical element. The engaged state may provide for one or more flat surfaces of the surgical element against one or more flat surfaces of the other element. For example, six flat surfaces may be opposed to six flat surfaces.

[0108] The fourth aspect of the present disclosure includes other aspects of the disclosure and may include any of the other features, features, options, or possibilities described herein, including any taken alone or in any combination. [Brief description of the drawings]

[0110] There is a need to provide mounting systems for surgical procedure components in a variety of situations, one particular instance where such mounting systems find use is in hip replacement procedures. The surgical procedure element may be a surgical instrument. Reamers, broaches, and files are all examples of such surgical instruments and therefore surgical procedure elements. They find particular use in the preparation of the femur to receive the femoral component of a hip replacement. During the procedure, the femoral canal needs to be prepared so that it is hollowed out with the appropriate shape to receive the stem of the femoral component. The surgical procedure element may be a trial component. For example, a trial stem is used to check the intended position set for the femoral component of a hip replacement and is therefore an example of such a surgical procedure element. The surgical procedure element may be the final part that is left in place after the surgical procedure, for example the stem of a hip replacement.

[0111] Generally, the surgical procedure element 1, in the case of a reamer, comprises a distal end provided with a cutting blade 3 and a proximal end 5 provided with a first connecting element 7. The first connecting element 7 cooperates with a second connecting element 9 provided on the distal end 11 of a force application device or extension element 13.

[0112] During operation, a first surgical procedure element 1 needs to be attached to a force application device 13, used and then replaced with a second surgical procedure element 13 and possibly further surgical procedure elements 13. Thus, a series of connecting and disconnecting operations needs to be performed. Figure 1a illustrates a disconnected state for the two elements and Figure 1b illustrates a similar connected state.

[0113] As an example, a set of reamers 1 are often provided in successively increasing diameters so that the reamer 1 can be used and then the femur can be cored to the desired diameter.

[0114] To connect the distal end 11 of the force application device 13 or extension element 13 to the proximal end 5 of the surgical procedure element 1, a configuration as shown in Figures 1a and 1b may be adopted. The proximal end 5 of the surgical procedure element 1 has an outer diameter smaller than the inner diameter of the collar 15 on the distal end 11 of the extension element 13. This allows the proximal end 5 to slide inside the extension element 11. Thus, a spigot and socket type configuration is provided. After insertion, engagement is provided by rotating the surgical procedure element 1 and the extension element 13 relative to each other to cause an interaction between an L-shaped slot 17 on the proximal end 5 and an internal element [not shown] in the collar 15.

[0115] To overcome the inherent resistance due to contact between the surgical technique element 1 and the extension element 13, an active twisting action needs to be applied to one or both of the surgical technique element 1 and / or the extension element 13. This can be difficult to achieve and means that a rotational load may be applied before actual engagement occurs, requiring verification to ensure proper alignment and engagement has been achieved. It is desirable to overcome these problems.

[0116] Although the context of the present disclosure has been described above with reference to a reamer 1 as the surgical procedure element 1, a wide variety of different surgical procedure elements 1 are suitable for employment with the present disclosure. Thus, a variety of different shapes of reamers 1 may be used. Different reamer shapes are often used for distal femoral canal preparation compared to reamer shapes used in the proximal femoral canal preparation and / or the mid femoral canal due, for example, to the different size and shape hollows required when different portions of the femoral component of a hip replacement are inserted.

[0117] In other situations or procedures, it may be preferable to use one or more broaches, one or more files, or a combination of reamers, broaches, and files in the preparation of the hollow, which may be connected to the extension element 13 in an equivalent manner.

[0118] In addition to its use in forming the bore, the extension element 13 or force application device 13 may be used to introduce the trial stem and / or the final stem.

[0119] With reference to FIG. 2, a perspective view of a female part 100 of a mounting system according to a first embodiment is seen. In keeping with the format seen in FIGS. 1a and 1b, the female part 100 is provided at the distal end 102 of an extension element [not shown], which extends away from the proximal end 104 of the female part 100. The female part 100 is typically welded to the distal end of the extension element [not shown]. The extension element includes connection features that allow torque and / or tension and / or compression to be applied to the extension element and thus to the female part 100, the male part 106 and the surgical technique element 108. Thus, the male part 106 [see FIGS. 8a, 8b, 8c] is provided on the surgical technique element 108. Of course, the elements comprising the female part 100 and the male part 106 are reversible.

[0120] The outer wall 110 of the female part 100 has three planar sections 112 and three intermediate partial cylindrical sections 114. Loads will typically be applied to the extension elements, but the planar sections 112 allow for interfacing with a tool [not shown] to allow torque to be applied to locations on the female part 100, if desired.

[0121] The female part 100 surrounds a bore 116 having an opening through which the male part 106 is received, the opening having a chamfered periphery 118 to aid in locating the male part 106 in the bore 116.

[0122] As illustrated in this embodiment, the mouth end 120, i.e., distal end 102, of the female part 100 includes a first internal profile section 122 that is cylindrical and smooth in profile. The first internal profile section 122 leads into a second internal profile section 124 in which an aligner 126 is provided, as can be seen in more detail in FIG.

[0123] The second inner profile section 124 is positioned intermediate the first profile section 122 , through which the male part 106 is received, and the third profile section 128 .

[0124] The third profile section 128 is provided with suitable configuration for receiving and engaging an extension element [not shown] that the female part is mounted on its distal end 102 .

[0125] 3, a transition surface 130 is provided at the interface between the first profile section 122 and the second profile section 124 and represents a reduction in cross-section of the bore 116. In this illustrated example, the reduction in cross-section is provided uniformly and thus represents a reduction in cross-sectional radius.

[0126] In the second profile section 124, a series of flat surfaces 132 are provided around the inner circumference of the bore 116. In the illustrated example, six such flat surfaces are provided to provide a set of engagement surfaces 134 which, in use, engage corresponding engagement surfaces 136 on the outer surface 138 of the male part 106 [as shown in Figure 8a]. The interaction of the set of female engagement surfaces 134 and male engagement surfaces 136, in use, allows for the effective transfer of torque between the two parts [as shown in Figure 9].

[0127] Returning to FIG. 3, still within the second profile section 124, but closer to the mouth end 120 [distal end 102 as shown] than the series of flat surfaces 132, an aligner 126 is provided.

[0128] 4, each aligner 126 extends medially within bore 116. The medial extent of each aligner 126 is configured to change the cross-sectional profile from a circular cross-sectional profile found at a start 140 of second profile section 124 to a hexagonal cross-sectional profile found at a further location 142 within second profile section 124.

[0129] While the male engagement surface 136 on the male part 106 may be presented at any rotation within the bore 116, while extending only within the first profile section 122 of the bore 116, or while still extending only within the beginning of the second profile section 124, alignment of the female engagement surface 134 and the male engagement surface 136 must occur before they can be engaged.

[0130] Rather than having to actively rotate the male part 106 and / or female part 100 relative to one another to find this mating alignment, the present disclosure uses an aligner 126 to achieve the required alignment.

[0131] 3, each aligner 126 is positioned axially forward of a planar surface 132 that is considered for insertion of the male part 106 into the female part 100. The aligners 126 define a first alignment surface 142 and a second alignment surface 144 with an apex surface 146 provided therebetween. The apex surface 146 is curved to provide a smooth transition between the first alignment surface 144 and the second alignment surface 144.

[0132] First alignment surface 142 has an axial extent within bore 116 and also has an annular extent around bore 116 thus defining an inclined surface.

[0133] A second alignment surface 144 is similarly provided but extends annularly in the opposite direction, thus defining an opposing ramp surface.

[0134] The intermediate profile 148 of the aligner 126 corresponds to the intermediate profile of the planar surface 132 through which the aligner passes.

[0135] Full details of the corresponding design of the male part 106 can be seen in Figures 8a, 8b and 8c and will be explained in detail below. Before that, a second embodiment of the female part will be explained with reference to Figures 5, 6 and 7.

[0136] The second embodiment of the female part 100 has many features in common with the first embodiment, and therefore this description will focus on the differences between the two. Similar parts in the two embodiments are given corresponding reference numerals in the drawings.

[0137] 5, a perspective view of the female part 100 shows the proximal end 104 of the female part 100, the outer wall 110 of the female part 100, and three planar sections 112 and three partial cylindrical sections 114 in between. Loads will typically be applied to the extension elements, but the planar sections 112 allow for interfacing with a tool [not shown] to allow torque to be applied at the female part 100, if desired.

[0138] The female part 100 surrounds a bore 116 which receives the male part 106 in use. The mouth end 120, as before, comprises a first internal profile section 122 which merges into a second internal profile section 124 in which an aligner 126 is provided.

[0139] With reference to FIG. 6, a transition surface 130 is provided at the interface between the first profile section 122 and the second profile section 124 and represents a reduction in the cross-section of the bore 116 .

[0140] Again, in the second profile section 124 a series of flat surfaces 132 are provided around the inner circumference of the bore 116 so that, in use, effective transmission of torque is achieved between the male and female parts.

[0141] 7, each aligner 126 again extends midway within bore 116. The mid-extent of each aligner 126 is configured to change the cross-sectional profile from a circular cross-sectional profile found at a start 140 of second profile section 124 to a hexagonal cross-sectional profile found at a further location 142 within second profile section 124.

[0142] As is evident from a comparison of Figures 5 and 6 with Figures 2 and 3, in the second profile section 124 of the second embodiment, the aligners 126 have a different profile. Each aligner 126 is still positioned axially forward of the flat surface 132 that is considered for insertion of the male part 106 into the female part 100. The aligners 126 still define a first alignment surface 142 and a second alignment surface 144 with an apex surface 146 provided therebetween. The apex surface 146 is curved to provide a smooth transition between the first alignment surface 144 and the second alignment surface 144.

[0143] The two embodiments differ with respect to the inclination angle of the first alignment surface 142 and the second alignment surface 144. As can be seen from Figures 5 and 6, the inclination angle is much smaller in the second embodiment.

[0144] With reference to a further embodiment, as shown in Figures 10a and 10b, the tilt angle will be explained in further detail.

[0145] 10b, the angle between the first alignment surface 142 at its intermediate edge 148 and the second alignment surface 144 at its intermediate edge 148 is considered. The total angle A between the two is, in this further embodiment, 150°±15°. In practice, this angle A can also be considered to be the apex angle of the flat surface 132 between the two intermediate edges 148.

[0146] 11a, 11b, and 11c, a second angle B is considered. This is the intermediate slope of the alignment surfaces 142, 144, and / or the apex surface 146. It can be defined as the angle between the central axis 400 and the inflection 402 of the apex surface 146, as shown in FIG. 11c. The inflection 402 represents a ridge defined by the transition from, for example, a first angular orientation of the first alignment surface 142 to, for example, an oppositely inclined second angular orientation of the second alignment surface 144. In still further embodiments, the total angle B between the two is 45°±5°. Angle B can be similarly defined between the central axis 400 and any line extending across the first alignment surface and / or the second alignment surface, where the line is axially aligned with the central axis 400 and / or follows a minimum distance across the alignment surface at that location.

[0147] Considering the angle A, the configuration of the first alignment surface 142 and the second alignment surface 144 in the second embodiment [FIGS. 5, 6] and / or the further embodiment [FIG. 10b] and / or the still further embodiment [FIGS. 11a, b, and c] means that a shorter axial travel distance is involved when rotating the parts into alignment than in the first embodiment [FIGS. 2 and 3]. This may reduce the ease of passive rotational alignment due to the application of an axial force because of the higher frictional forces encountered, but the angle is still sufficient to deliver passive rotational alignment in response to the user applying an axial force pressing the female part against the male part. In this context, passive rotation is rotation caused by an applied axial force, which causes the female part profile to interact with the male part profile without the user applying any rotational force or actively trying to rotate to increase alignment. Once aligned, user applied axial force never causes further rotation and the female part only advances axially over the male part.

[0148] Overall, the present configuration represents a good balance between this goal of passive rotational alignment when the user applies an axial compressive force and the competing goal of providing sufficient engagement area between the female and male parts for sufficient torque transmission, while staying within the maximum allowable size of the female part given the limited space requirements that can be made within the operating environment. Substantially expanding the size of the female part to allow for a larger torque transmission surface is not a desirable option in the surgical environment in which the present system may be used.

[0149] The proportion of the circumference of the bore 116 that is occupied by the flat surface 132 is higher in the second embodiment [FIGS. 5, 6] and / or the further embodiment [FIG. 10b] and / or the yet further embodiment [FIGS. 11a, b, and c] than in the first embodiment [FIGS. 2 and 3], thus aiding torque transmission.

[0150] 5, in one of the three planar sections 112 of the outer wall 110, the second embodiment provides a through opening 200 that leads to the third profile section 128 and allows visual confirmation that the male part 106 has been correctly axially inserted into the female part 100.

[0151] Turning to FIG. 8a, a male part 106 is provided at the proximal end 300 of the surgical procedure element 108. The male part 106 has an open central bore 302 surrounded by an end face 304, which is annular in the illustrated form. A transition face 306 extends between the end face 304 and an initial element 308 of an engagement section 310 provided by the male part 106. The engagement section 310 is formed by opposing elements to those provided on the female part 100. The engagement section 310 thus provides three planar sections 136 and three partial cylindrical sections 312 intermediate them.

[0152] At the proximal most portion of the engagement section 310, the male part 106 presents a radially outward tapered surface 314 that receives the aligner 126 when properly aligned.

[0153] Distal beyond the engagement section 310, the male part 106 presents a second transition surface 316 that leads into a removable gripping section 318. The removable gripping section 318 is formed with a series of grooves and ridges. As shown, looking at FIG. 8b, these are axially aligned, although other orientations may be used. In the illustrated embodiment, the gripping section 318 has a reduced cross-sectional profile at an intermediate location 319 between the two ends of the gripping section 318.

[0154] The grasping section 318 is followed distally by a secondary engagement section 320. The secondary engagement section 320 includes a series of flat surfaces 322 that allow for the application of torque to the surgical element 108, if desired.

[0155] The fully engaged configuration of the female part 100 and the male part 106 can be seen in FIG.

[0156] In operation, the female part 100 and the male part 106 are brought together and the proximal end 300 of the male part 106 enters the bore 116 of the female part 100. The first profile section 122 allows for introduction at any rotational position. The only movement at this stage is axial movement of the female part 100 and the male part 106 relative to each other.

[0157] Eventually, axial movement of the female part 100 and the male part 106 towards each other will bring the proximal end portion 324 of the partial cylindrical section 312 in the engagement section 320 of the male part 106 into contact with a portion of the aligner 126 in the female part 100. The contact may be with the apex surface 146 of the aligner 126. The configuration of the apex surface 146 helps to facilitate rotation of any portion of the male part 106, i.e. the proximal end portion 324, which will most likely be encountered first. This rotation is passively induced in response to an axial force applied by the user due to the shape and configuration employed. This will bring the proximal end portion 324 of the male part 106 into contact with one of the first alignment surface 142 or the second alignment surface 144, thus providing further rotation of the male part 106 and the female part 100 relative to each other. Continued application of axial force causes continued rotation, and more generally, causes increasing alignment of the proximal end portion 324 and partial cylindrical section 312 of the male part 106 with the gap 152 between the first alignment surface 142 and the second alignment surface 144.

[0158] Once rotationally aligned, continued axial-only movement of the female and male parts 100, 106 is caused to slide relative to one another. This results in a full range of axial movement of the female and male parts 100, 106 towards one another and thus full alignment and opposition of the set of female mating surfaces 134 with the set of male mating surfaces 136.

[0159] The aligner 126 configuration provides for axial movement of the male part 106 and the female part 100 towards each other, causing passive rotation and therefore alignment of the female engagement surface 134 with the male engagement surface 136. In effect, a passive radial self-alignment is provided. Thus, both radial and rotational locking are achieved in a simple and reliable manner. For example, a chamfer alone would only achieve axial alignment and would not provide any rotational locking.

[0160] While achieving these benefits, it can be seen, particularly from FIG. 4, that the present approach adds very little material thickness to the design and is therefore a suitable approach for use in systems that must operate in small spaces, such as pin drivers.

[0161] The inclination of the first and second alignment surfaces 142, 144 may be depicted as required for the application under consideration. In general, increasing the inclination of the alignment surfaces will provide easier alignment, while decreasing the inclination will provide greater torque capacity. The application and the need to operate the surgical procedural elements will guide the appropriate configuration.

[0162] In all of the embodiments shown, the aligners 126 are configured to provide rotational alignment by relatively rotating the male part 106 and / or the female part 100 in either direction. By modifying the profile of the aligners 126, unidirectional alignment can be employed. In this configuration, only a single alignment surface 142 or alignment surface 146 is provided on each aligner 126, each annularly inclined in the same direction, depending on the rotational direction desired to achieve alignment. The single alignment surface 142, 144 used is larger than in the illustrated embodiment.

[0163] While the concepts of the present disclosure are susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail, however, it should be understood that it is not the intention of this disclosure to limit the concepts of the present disclosure to the particular forms disclosed, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the present disclosure and the appended claims.
