Description

[Technical Field]

[0001] [Cross-Reference to Related Application] The present application claims all priority and benefits of U.S. Provisional Patent Application No. 62 / 517,33 filed on June 9, 2017 , the entire content of which is hereby incorporated herein by reference. [Background Art]

[0002] Conventional medical and surgical procedures typically employ battery-powered surgical systems, such as drills, sagittal saws, and other tools. Such battery-powered surgical systems allow surgeons to access and perform procedures at surgical sites where corded connection to a power source, console, or the like is undesirable. Surgical tools of this type are generally configured to be releasably attached to a rechargeable battery pack that supplies power to the tool until the charge is depleted. Both the tool and the battery pack are typically designed to be used multiple times and manufactured to be cleanable and sterlizable when not in use.

[0003] It should be understood that the charge of a single battery pack may be insufficient for some procedures, such as extensive drilling or cutting with a tool. In such cases, when the charge of one battery pack is depleted, the surgeon will remove the depleted battery pack from the tool , attach another charged battery pack to the tool, and then continue the procedure . Thereafter, the depleted battery pack is cleaned, sterilized, recharged, and then reused in other procedures.

[0004] ​​Conventional battery-powered surgical systems generally perform well for their intended use. However, the series of steps required to remove the battery pack from the tool can be difficult. The reasons are to avoid, in particular, disconnection of wires or damage to electrical contacts due to carelessness during use, and to reduce vibration and noise. To reduce and prevent contamination from entering between the tool and the battery pack, the tool and Battery packs are often designed to be sealed or to engage tightly with each other. This is because it is done in this way. For this reason, removing the battery pack may, in some cases, Damage to a part of the tool or battery pack, resulting in safety and / or handling issues. This can lead to problems. Therefore, in this industry, one or more of these drawbacks may be It is necessary to take action.

The contents are included herein by reference.

[0066] Typical embodiments shown herein include the handpiece connector 48 and the battery connector Electrical connection between the handpiece 36 and the battery 34 due to physical contact of the connector 68 Although aimed at facilitating communication, electrical communication is achieved through numerous different methods. Please understand that this is acceptable. For example, the handpiece data connection section 46 Electrical communication between D and the battery data connection part 66D is used to transmit data and / or information. This may be done using a transmitter and receiver configured to communicate via a wire. To achieve this goal, Near Field Communication (NFC), Radio Frequency Identification (RFID), and Wi-Fi are used.

Also, the The bottle 32 is connected to the battery connector 68 in the same way as the handpiece connector 48. If the charger 38 is (see Figure 2), then in order to charge the battery 34, this physical connection A contact method may be used. However, as those skilled in the art will know, the battery 34 can be provided by various means. For example, the charger 38 is physically / electrically connected to the battery connector 68. You will understand that it may be charged by any other method. According to an unrestrictive example, The Terry 34 uses a charging coil (not shown) configured for wireless inductive charging. It's possible to have it. Other configurations are also possible.

[0068] As mentioned above, the surgical system 30 is secured by a "twist-lock". The battery 34 and handpiece are connected via the battery connector 68 and the handpiece connector 48. It is configured to smoothly achieve physical and electrical communication with -36. To achieve the target, the handpiece connector 4 is as best shown in Figures 8 to 10. 8 is the first coupler 74, the first handpiece terminal 76A, and the second handpiece terminal 7 It is equipped with terminals 6B and a third handpiece terminal 76C. Alternatively, the first handpiece Terminal 76A and the third handpiece terminal 76C are, respectively, handpiece power terminal 76 A and the handpiece grounding terminal 76C may be characterized as such. Alternatively, terminal 7 6A and 76C may generally be identified as handpiece voltage terminals 76A and 76C. Alternatively, the second handpiece terminal 76B is specifically designated as the handpiece data terminal 76B. It may also be specified. Similarly, as best shown in Figures 4 to 6, battery connector 6 8 is a second coupler 78 configured to rotatably engage with the first coupler 74, First battery terminal 80A, second battery terminal 80B, and third battery terminal It is equipped with 80C. Alternatively, the first battery terminal is 80A and the third battery terminal is 80A. 80C refers to the battery power terminal 80A and the battery ground terminal 80C, respectively. It may be marked as such. Alternatively, terminals 80A and 80C are generally battery voltage terminals. It may be identified as sub-terminals 80A and 80C. Alternatively, the second battery terminal 80B is It may also be identified as the battery data terminal 80B. The following describes each of these components: I will explain in detail.

[0069] Referring to Figures 11A to 11C below, the distance between the battery 34 and the handpiece 36 Several steps for making a "twistlock" connection are shown sequentially in Figure 1. 1A shows a perspective view of battery 34. In the figure, the battery connector 68 The second coupler 78 defines axle AX, and the battery terminal 80A is centered on this axle AX. 80B and 80C are located. Figure 11B shows the han located above battery 34. The handpiece 36 is shown. The first coupler 74 of the handpiece connector 48 is connected to shaft AX It is aligned with the center and the initial radial position IRP relative to the battery connector 68. It is positioned. Figure 11C shows it positioned along axis AX in its initial radial position IRP. This shows the handpiece 36 moving toward the battery 34 (Figure 11C and Figure 11 (Compare with B). As will be explained in more detail below, the second coupler 78 is the initial half The first coupler 74 is accepted at the radial position IRP, and the initial radial position IR Relative axial shift between the battery 34 and the handpiece 36 along axis AX at P It is configured to enable movement.

[0070] Once the battery connector 68 is in its initial radial position IRP as shown in Figure 11C If the handpiece connector 48 is accepted, then the initial radial position IRP is shown in Figure 1. Figures 1D and 11E show the relative axial direction between the battery 34 and the handpiece 36. (Directional movement is constrained) Batch of the handpiece 36 to multiple different fixed radial positions Terry 34 can be rotated. As multiple different fixed radial positions, the first fixed radius Directional position SRP1 (see Figures 11D and 12C), second fixed radial position SRDP2 (Figure Examples include the 12D, and the final fixed radial position SRPF (see Figures 11E and 12E). For each of these fixed radial positions, please refer to Figures 12A to 12E below. I will explain this in more detail. Additional fixed positions are also possible.

[0071] In a typical embodiment shown throughout the drawings, the first fixed radial position S RP1 occurs between the first handpiece terminal 76A and the first battery terminal 80A. The second fixed radial position SRP2 is defined by the initial engagement (see Figure 12C), and the second fixed radial position SRP2 is defined by the second The initial engagement that occurs between the handpiece terminal 76B and the second battery terminal 80B It is defined (see Figure 12D). However, as will be clear from the following explanation, the first and second The fixed radial positions SRP1 and SRP2 are (between the battery 34 and the handpiece 36). Between the handpiece connector 48 and the battery connector 68 (where relative movement is restricted) It may be defined by a number of different forms based on any suitable orientation.

[0072] Referring to Figures 4 to 12E, the handpiece terminal 76A of the handpiece connector 48, 76B, 76C and battery terminals 80A, 80B, 80C of battery connector 68 are Each of them, as follows, namely, the second coupler 78 accepts the first coupler 74. From the initial radial position IRP (see Figure 12B), the first fixed radial position SRP1 ( By rotating (see Figure 12C), the first handpiece terminal 76A connects to the first battery cord. It engages with the connector 80A and moves from the first fixed radial position SRP1 (see Figure 12C) to the second fixed position By rotating to the constant radial position SRP2 (see Figure 12D), (the first handpiece terminal) (While maintaining engagement between 76A and the first battery terminal 80A) the second handpiece terminal 76B is positioned to engage with the second battery terminal 80B. Therefore, During rotation of the battery 34 relative to the piece 36, the engagement of the first terminals 76A, 80A is This occurs before the engagement of terminals 78B and 80B of the second terminal. In the illustrated embodiment, the third terminal 76C, The engagement of 80C occurs simultaneously with the first terminals 76A and 80A, so the second terminals 78A and 8 This will occur before engagement of 0A.

[0073] The arrangement of terminals 76A, 76B, 76C, 80A, 80B, and 80C as described above results in the Hampi Please understand that electrical communication between -36 and battery 34 occurs in a specific order. . In a non-limiting example, in one embodiment, the first handpiece terminal 76A, that is, The handpiece power terminal is electrically connected to the handpiece power connection part 46P, and the first The battery terminal 80A, that is, the battery power terminal, is the battery power connection part 66 It is electrically connected to B. Also, the second handpiece terminal 76B, that is, hand The piece data terminal is electrically connected to the handpiece data connection section 46D, and the second battery The battery terminal 80B, i.e., the battery data terminal, is connected to the battery data connection section 66D. It is electrically connected to the third handpiece terminal 76C, that is, the handpiece - The grounding terminal is electrically connected to the handpiece grounding connection part 46G, and the third battery Terminal 80C, i.e., the battery ground terminal, is electrically connected to the battery ground connection part 66G. They are connected. Here, from the initial radial position IRP (see Figure 12B) to the first fixed radius When rotation occurs to the directional position SRP1 (see Figure 12C), the first handpiece terminal 76 A engages with the first battery terminal 80A, and the handpiece power connection part 46P is connected to the battery The power connection terminal 66P is electrically connected, and the third handpiece terminal 76C is connected to the third battery. -Engages with terminal 80C, and the handpiece ground connection part 46G connects to the battery ground connection part 66G. Electrically connected. However, at the initial radial position IRP, the second handpiece end Child 76B remains in a position disengaged from the second battery terminal 80B, As a result, at the first fixed radial position SRP1, the handpiece data connection section 46 This means that there is no electrical connection between D and the battery data connection part 66D. In other words, Before data is communicated between the battery 34 and the handpiece 36, the power connection and connection are established. A ground connection is established between the battery 34 and the handpiece 36, and between the cell 64 and the handpiece Power can be transmitted between the control device 48 and the battery 34 and the handpiece 36. Data communication between them is from the first fixed radial position SRP1 (see Figure 12C) to the second fixed semicircular position. This occurs after a subsequent rotation to the radial position SRP2 (see Figure 12D).

[0074] Referring to Figure 13, power and ground connections are made to battery 34 and H&B before data communication. In order to ensure that an agreement is reached with the dopiece 36, in one embodiment, the first The first handpiece terminal 76A and the second handpiece terminal 76B are handpiece terminal arcs. The first battery terminals are spaced apart radially from each other by a length AL1 with respect to the axis AX. The second battery terminal 80A and the second battery terminal 80B have different (handpiece terminal arc lengths ALL) The battery terminals are spaced apart radially from each other, with the arc length AL2 being the center axis AX. In the typical embodiment shown in Figure 13, the battery terminals are 80A, 80B, 8 0C is a point that is equidistant from each other in the radial direction with axis AX as the center, and is located at the handpiece terminal. 76A, 76B, and 76C are spaced unequally apart from each other in the radial direction, with axis AX as the center. This arrangement allows for the following differences in the arc length of the handpiece terminals AL1 and the arc length of the battery terminals. A difference will arise between this and AL2. However, a person skilled in the art will know the handpiece terminal 7 Other arrangements of 6A, 76B, 76C and / or battery terminals 80A, 80B, 80C may be used. They will understand that it is okay for them to be there.

[0075] Referring to Figures 8 to 10, the first coupler 74 of the handpiece connector 48 is the first It comprises a coupler member 82, a terminal retainer 84, and one or more biasing elements 86. This is good. In the typical embodiment shown in Figure 10, the first coupler member 82 is a flange It has a part 88 and a socket part 90. The flange part 88 has a flat, substantially ring-shaped front As described above, it is configured to be attached to the body of the handpiece 36. The part 90 extends from the flange part 88 to the first coupler end 92 and the outer surface 94 of the first coupler and has a substantially tapered cylindrical contour defining the inner surface 96 of the first coupler. The outer surface 94 of the first coupler and the inner surface 96 of the first coupler are, respectively, connected to the second coupler 78. Shaped to guide the engagement of the 74. Handpiece terminals 76A, 76B, 7 6C is located inside the socket part 90 (see Figure 9). Also, the first coupler 74 is Multiple tabs 98A, 98B, 98C, 98 extending outward from the outer surface 94 of the first coupler It has D. Multiple, for example, three alignment tabs 98A, 98B, 98C, on axis AX. Centered at this point, they are spaced apart radially, and as will be explained in more detail below, the initial half In the radial position, ensure proper alignment of the battery 34 and the handpiece 36. The stop tab 98D is connected to the handpiece 36, as will be explained in more detail below. The axial and semi-axial directions restrict the relative rotational indexing of the battery 34 to the SRPF position. They are arranged radially.

[0076] Referring further to Figure 10, the terminal retainer 84 is connected to the handpiece terminals 76A, 76B, 7 It supports 6C and is positioned between the first coupler member 82 of the handpiece 36 and the main body 44. The terminal retainer 84 is equipped with an alignment key 100. The alignment key 100 is The first coupler member 82 of the handpiece 36 and the pair formed inside the main body 44, respectively. Shaped to be positioned within corresponding alignment pockets 102, 104 Appropriateness of handpiece terminals 76A, 76B, 76C to tabs 98A, 98B, 98C This ensures precise alignment. The biasing element 86 also provides a first force to the handpiece 36. Interposed between the puller member 82 and the main body 44, within the flange portion 88 of the first coupler member 82 It is seated within another biasing opening 106 defined therein. In the illustrated embodiment, the biasing element Each of the 86 has a curved, roughly rectangular contour and engages with the portion of the battery connector 68. Then, move the handpiece connector 48 along axis AX away from the battery connector 68. It is configured to be biased, thereby preventing accidental movement from fixed radial positions SRP1 and SRP2. To prevent unintentional rotation and to provide consistent tactile feedback during rotation between the battery 34 and the handpiece 36. This will result in the following: Also, the biasing element 86 is connected to the handpiece 36 in use and the battery 0 34 reduces noise and / or vibration, thereby improving handling comfort, and also Endpiece terminals 76A, 76B, 76C and / or battery terminals 80A, 80B, 80 To reduce wear on components that may occur between one or more C components.

[0077] Referring to Figures 4 to 7, in the typical embodiment shown therein, the battery connector The second coupler 78 of 68 consists of a second coupler member 108 and a second coupler member 108 It is equipped with a second coupler passage 110 formed adjacent to it (see Figure 5). The puller member 108 engages with the inner surface 96 of the first coupler of the handpiece connector 48. The second coupler member surface 112 is defined in a uniform shape. Second coupler passage 110 The inner surface of the passage 1 is shaped to engage with the outer surface 94 of the first coupler of the handpiece 48. 14 is defined. Therefore, the socket of the first coupler 74 of the handpiece connector 48 Section 90 is the second coupler passage 110 of the second coupler 78 of the battery connector 68. It is shaped to be positioned inside. Here, the second coupler member 108 is the first coupler The puller 74 has a tapered, substantially cylindrical contour that is shaped complementary to the socket portion 90, This guides the engagement of the handpiece connector 48 with the battery connector 68. That would be the case. Other outlines are also possible.

[0078] As best shown in Figure 5, the second coupler 78 of the battery connector 68 The coupler member 108 extends to the second coupler end 116. Battery terminal 80 Multiple receptacles 118A, 118B, 118C, which accommodate A, 80B, and 80C, It is formed within the coupler ends 116 of the two. More specifically, the receptacles 118A and 118 B and 118C each have an insertion portion 120 and an engagement portion 122. Battery terminal 8 0A, 80B, and 80C are the engagements of receptacles 118A, 118B, and 118C, respectively. It is seated within part 122 and spaced apart from the insertion part 120. The insertion part 120 is initially At the radial position (see Figure 12B), the handpiece terminals 76A, 76B, and 76C are axially positioned It is shaped to accept in the direction.

[0079] Referring further to Figure 5, the battery connector 68 is shaped adjacent to the second coupler 78. It is equipped with multiple elongated holes 124A, 124B, and 124C. These elongated holes 124A ,124B,124C are handpieces at the initial radial position IRP (see Figure 12B). Each tab 98A, 98B, 98C of the connector 48 accepts the initial radial position Handpiece 3 between IRP and multiple fixed radial positions SRP1, SRP2, SRPF This is to enable the rotation of battery 34 relative to 6. Therefore, each of the elongated holes 124A, 124B, and 124C is located at the initial radial position IRP.

To prevent relative axial movement between 6 and fixed radial positions SRP1, SRP2 , shaped to engage with tabs 98A, 98B, and 98C respectively in the SRPF To achieve this objective, tabs 98A, 98B are used, as best shown in Figure 9. Each of 98C defines a tab fixing surface 132. The tab fixing surface 132 is tab 98A ,98B,98C are positioned within the radial portion 128 of the elongated holes 124A, 124B,124C. When this happens, the fixed surface 130 of the elongated holes is defined by each of the elongated holes 124A, 124B, and 124C. It is positioned so as to be in contact with (compare Figure 12C with Figure 12B). Several actual In the configuration, the tabs 98A, 98B, and 98C of the handpiece connector 48 are, respectively, transition surfaces. It is equipped with a chamfering section 134 (see Figure 9). The transition chamfering section 134 is at an initial radial position IR From P (see Figure 12B), multiple fixed radial positions SRP1, SRP2, SRPF (Figure 12 It is shaped to facilitate movement to one of the C (see Figure 12E). In one embodiment, , one of the elongated holes 124A, 124B, 124C, for example, the radial portion 12 of the elongated hole 124C 8 defines the elongated hole stop surface 136C (shown by dashed lines in Figures 7 and 12A to 12E). The elongated hole stop surface 136C is located at the final fixed radial position SRPF (see Figure 12E). Then, one of the corresponding tabs 98A, 98B, 98C, for example, tab 98C, stop surface 138C It is shaped to contact (see Figures 12B to 12E). In this embodiment, The handpiece stop tab 98D and the battery stop tab 129 are as described below. It is not always necessary. In an alternative configuration where contact between surfaces 136C and 138C is not required, The battery stop tab 139 protrudes from the inner surface 114 of the passage toward the shaft AX, and the battery stop tab The stop surface 136D is defined. Meanwhile, the handpiece stop tab 98D is positioned from surface 94 (from axis AX). It extends outward (away from the body) and defines the handpiece stop surface 138D. Tabs 139, 98 D is shown as essentially a cube, but separates from faces 136D and 138D. It may have alternative shapes (e.g., triangles, arcs) extending in that direction. Face 136D,1 38D should be coplane extending from axis AX. Handpiece stop tab 98D and battery The battery stop tab 139 is connected to the handpiece stop surface 138D and the battery stop surface 136D.
