Description

Technical Field

[0001] The present invention relates to a device, and in particular to an adjustable marking reference device suitable for identifying surgical instruments. Background Art

[0002] The spinal surgery navigation systems on the market generally use Northern Digital Inc. (NDI) optical recognition system as the positioning basis. The various instruments used in navigation surgery need to be combined with different dynamic reference frames (DRF) to facilitate optical system recognition.

[0003] In practical applications, taking spinal fusion surgery as an example, surgical instruments such as drills, cannulas, K-wires, trocars, taps and screwdrivers may be used during the process.

[0036] See also Figures 1 to 5 As shown, the first embodiment of the present invention provides an adjustable marking reference device D suitable for identifying surgical instruments, which includes a base 1, an upper cover 2, a connecting rod group 3, a plurality of markings 4 and a fixing button 5.

[0037] The base 1 may be, for example, Figure 2 The rigid plate shown has a first groove 10 on its upper surface S1. The upper surface of the base 1 is also provided with a first protrusion 12 and a second protrusion 14. A main recess 16 is formed between the first protrusion 12 and the second protrusion 14. The first groove 10 is provided at the bottom of the main recess 16.

[0038] From a top view, the first protrusion 12 may have a hill shape similar to a triangle and have a plurality of first positioning surfaces SP1 facing the main recess 16, and the second protrusion 14 may have a shape similar to the letter H, and the upper half of the letter H forms a plurality of second positioning surfaces SP2 facing the main recess 16. The first positioning surfaces SP1 and the second positioning surfaces SP2 are both perpendicular to the upper surface S1 of the base 1.

[0039] The upper cover 2 is disposed on the base 1 and is provided with a second groove 20 corresponding to the first groove 10. In some embodiments, the upper cover 2 has the same shape as the base 1 (from a top view), similar to the shape of the letter H, and a third protrusion 22, a fourth protrusion 24 and a main recess 26 may be formed on the lower surface S2 of the upper cover 2 to correspond to the first protrusion 12, the second protrusion 14 and the main recess 16, respectively, to provide more space for the connecting rod assembly 3 when combined with the base 1, so as to allow the connecting rod assembly 3 to use a thicker rod body.

[0040] The connecting rod assembly 3 is disposed between the base 1 and the upper cover 2, particularly in the main recesses 16, 26, and has two movable ends E1, E2 and a pivot point P. Please refer to Figure 2 Specifically, the connecting rod assembly 3 includes a first rod 30 and a second rod 32 disposed in the main recess 16, one end 301 of the first rod 30 is connected to one end 321 of the second rod 32 as a pivot point P, and the other end 302 of the first rod 30 and the other end 322 of the second rod 32 serve as movable ends E1 and E2, respectively. Figure 2 As shown, the first rod body 30 is connected to one end 301 of the second rod body 32 and is provided with a first fixing hole H1, and the second rod body 32 is connected to one end 321 of the first rod body 30 and is provided with a second fixing hole H2, and one end 301 of the first rod body 30 and one end 321 of the second rod body 32 have complementary stepped structures, so that after being connected to each other, a pivot point P for the fixing button 5 to pass through can be formed.

[0041] In some embodiments, at least one auxiliary groove 18 may be further provided at the bottom of the main recess 16. For example, the number of the auxiliary grooves 18 may be two, and include a first auxiliary groove 181 and a second auxiliary groove 182, both of which are provided at the bottom of the main recess 16. However, the present invention is not limited thereto. In the embodiment provided with the auxiliary grooves, a first positioning pin 303 may be provided correspondingly on the surface of the first rod body 30 facing the base 1, and a second positioning pin 323 may also be provided correspondingly on the surface of the second rod body 32 facing the base 1. Therefore, the first auxiliary groove 181 may be used to assist in positioning the first positioning pin 303, and the second auxiliary groove 182 may be used to assist in positioning the second positioning pin 323.

[0042] like Figure 1As shown, a plurality of marks 4 can be respectively disposed on the upper cover 2 and the two movable ends E1 and E2 of the connecting rod assembly 3, and can be, for example, reflective balls. For example, the number of marks 4 is 4, such as Figure 2 As shown, the first mark 41 is connected to one end 302 of the first rod 30, and the second mark 42 is connected to the other end 322 of the second rod 32. The third mark 43 and the fourth mark 44 are arranged on the upper cover 2, for example, arranged at the two outwardly extending ends of the lower half of the letter H. The upper cover 2 and the base 1 are fixed to each other by locking screws (not shown) at a plurality of locking holes L on the first protrusion 12, the second protrusion 14, the third protrusion 22 and the fourth protrusion 24. The first mark 41, the second mark 42, the third mark 43 and the fourth mark 44 can be configured with metric screws, and the one end 302 of the first rod 30, the one end 322 of the second rod 32 and the upper cover 2 where the third mark 43 and the fourth mark 44 are predetermined to be arranged can also be configured with corresponding locking holes to fix each other. The present invention does not limit the way of setting these marks 4.

[0043] Please refer to Figure 2 , the fixed button 5 penetrates the first groove 10, the pivot point P and the second groove 20. The fixed button 5 includes a button body 50, an elastic member 52 and a bottom fixing pin 54. The button body 50 has a pressing portion 501 and a connecting rod portion 502 opposite to the pressing portion 501. The elastic member 52 can be, for example, a spring or a similar component, and is disposed between the connecting rod assembly 3 and the upper cover 2. The bottom fixing pin 54 is connected to the end of the connecting rod portion 502.

[0044] Among them, the fixing button 5 passes through the first fixing hole H1 and the second fixing hole H2 to penetrate the first groove 10, the pivot point P and the second groove 20, so as to fix the first rod body 30 and the second rod body 32 to the base 1 and the upper cover 2, and the connecting rod part 502 passes through the second groove 20, the elastic member 52, the first fixing hole H1, the second fixing hole H2 and the first groove 10 and is connected to the bottom fixing pin 54.

[0045] In some embodiments, the fixed button 5 may further include a support kit 51 having a groove for accommodating the button body 50 , and a through hole at the bottom of the groove for allowing the connecting rod 502 to pass through, thereby increasing stability when pressing the button body 50 .

[0046] Therefore, when the fixing button 5 is pressed, the connecting rod assembly 3 can move the pivot point P along the first groove 10 and the second groove 20. The first groove 10 and the second groove 20 each have at least three anchoring positions. When the fixing button 5 is not pressed and the pivot point P is located at one of the default positions P1, P2, P3 defined by the first groove 10 and the second groove 20, the connecting rod assembly 3 is fixed.

[0047] For example, when the pivot point P is located at the default position P1, P2 or P3 and the connecting rod assembly 3 is fixed, at least one of the first positioning surfaces SP1 and at least one of the second positioning surfaces SP2 abuts against the connecting rod assembly 3. Through these three anchoring locations, the marker 4 can have at least three configuration relationships when the connecting rod assembly 3 is fixed corresponding to these default positions P1, P2, P3. However, the present invention is not limited thereto.

[0048] For example, from Figure 5 It can be seen that the first groove 10 is respectively provided with a plurality of fixing grooves 101, 102, 103 corresponding to the bottom fixing pin 54 at the default positions P1, P2, and P3, and the fixing groove 101 can be connected to the fixing groove 102 through the track groove 104, and the fixing groove 102 can be connected to the fixing groove 103 through the track groove 105. It should be noted that the shapes of the fixing grooves 101, 102, and 103 are circular slots in the bottom view, and their diameters are slightly larger than the diameter of the bottom fixing pin 54 so that the bottom fixing pin 54 can pass through when the fixing button 5 is pressed. On the other hand, the width of the track grooves 104 and 105 can be slightly larger than the diameter of the connecting rod portion 502, but smaller than the diameter of the bottom fixing pin 54, so as to form a fixing structure for fixing the fixing button 5 together with the pivot point P (i.e., one end 301 of the first rod body 30 and one end 321 of the second rod body 32) at the default positions P1, P2, P3 when the bottom fixing pin 54 is located in the fixing grooves 101, 102, 103, thereby forming a so-called anchoring position.

[0049] At the same time, it should be noted that, similar to the first groove 10 and the second groove 20, the first auxiliary groove 181 and the second auxiliary groove 182 also have at least three anchoring parts respectively, and the first groove 10, the second groove 20, the first auxiliary groove 181 and the second auxiliary groove 182 are not only similar in shape (for example, all are V-shaped), but also the positions of the anchoring parts therein are highly correlated.

[0050] Please refer to Figure 6 , which is a top view schematic diagram of a first configuration relationship of an adjustable marking reference device according to an embodiment of the present invention. Figure 6 In the figure, the upper cover 2 is omitted to facilitate the description of the positional relationship between the first mark 41, the second mark 42, the third mark 43 and the fourth mark 44, the first rod 30 and the second rod 32 relative to the base 1. In the first configuration relationship, one surface of the first rod 30 facing the second protrusion 14 abuts against the positioning surface SP21 of the second protrusion 14, and the connection between the first rod 30 and the second rod 32 (i.e., the pivot point P) is fixed at the fixing button 5. Figure 5In the default position P1 of the second rod body 32, a surface of the second rod body 32 facing the first protrusion 12 abuts against the positioning surface SP11 of the first protrusion 12. Through the configuration of the positioning surface SP11, the positioning surface SP21, the first auxiliary groove 181, the second auxiliary groove 182 and the fixing groove 101, the first rod body 30 and the second rod body 32 can be stably supported in various operating conditions without changing the relative position relationship of the first mark 41, the second mark 42, the third mark 43 and the fourth mark 44.

[0051] At the same time, you can also refer to Figure 7 , which is a schematic diagram of the fixing button of the adjustable marking reference device according to the embodiment of the present invention being pressed. The first positioning pin 313 is assisted by the first auxiliary groove 181 to be positioned at one end of its V-shape, and the second positioning pin 323 is assisted by the second auxiliary groove 182 to be positioned at one end of its V-shape. In detail, when the bottom fixing pin 54 is located in the current fixing groove (e.g., the fixing groove 101) and the button body 50 is pressed, the bottom fixing pin 54 is moved along the fixing groove 101. Figure 7 101, so as to allow the connecting rod portion 502 of the button body 50 to move from the current fixing groove 101 to another fixing groove 102 along the track groove 104, and at the same time allow the marks 4 to switch from the current configuration relationship to another configuration relationship. When the button body 50 is pressed, one end of the elastic member 52 abuts against a part of the connecting rod assembly 3 to present a compressed state, and the connecting rod portion 502 of the button body 50 drives the bottom fixing pin 54 to leave the fixing groove 101 outward.

[0052] Please refer to Figure 8 and Fig. 9 , Figure 8 is a schematic diagram of a fixed button of an adjustable marking reference device according to an embodiment of the present invention being moved to another default position, Fig. 9 Schematic diagram of the fixed button of the adjustable marking reference device according to the embodiment of the present invention when being released. When the connecting rod portion 502 of the button body 50 moves from the current fixed slot 101 along the track slot 104 (i.e., direction D2) to another fixed slot 102, as the first rod body 30 and the second rod body 32 are driven, the first positioning pin 313 moves from one end of the first auxiliary groove 181 to the turning point of the V-shape, and the second positioning pin 323 also moves from one end of the second auxiliary groove 182 to the turning point of the V-shape.

[0053] Then, if Fig. 9As shown, if the button body 50 is no longer pressed (i.e. released), the bottom fixing pin 54 is allowed to enter the fixing groove 102, so that the connecting rod assembly 3 is fixed, and at the same time, the marks 4 are switched to another configuration relationship. When the button body 50 is released, the elastic member 52 returns to an uncompressed state, and the other end of the elastic member 52 pushes against the button body 50, so that the connecting rod portion 502 drives the bottom fixing pin 54 back to the fixing groove 102.

[0054] Please refer to Fig.10 , which is a top view schematic diagram of the second configuration relationship of the adjustable marking reference device according to an embodiment of the present invention. Fig.10 In the figure, the upper cover 2 is omitted for convenience of description. In the second configuration relationship, the surface of the first rod body 30 facing the first protrusion 12 abuts against the positioning surface SP12 of the first protrusion 12, and the connection between the first rod body 30 and the second rod body 32 (i.e., the pivot point P) is fixed at the default position P2 along with the fixing button 5. In addition, the surface of the second rod body 32 facing the second protrusion 14 abuts against the positioning surface SP22 of the second protrusion 14. Through the configuration of the positioning surface SP12, the positioning surface SP22, the first auxiliary groove 181, the second auxiliary groove 182, and the fixing groove 102, the first rod body 30 and the second rod body 32 can be stably supported in various operating conditions without changing the relative position relationship of the first mark 41, the second mark 42, the third mark 43, and the fourth mark 44.

[0055] Please refer to Fig.11 , which is a top view schematic diagram of the third configuration relationship of the adjustable marking reference device according to an embodiment of the present invention. Similar to the above operation, in the second configuration relationship, the button body 50 can be pressed to make the bottom fixing pin 54 leave the fixing groove 102, and the button body 50 can be pushed so that the connecting rod portion 502 can move from the current fixing groove 102 along the track groove 105 to another fixing groove 103, and then the fixing button 5 is released to make the bottom fixing pin 54 enter the fixing groove 103, thereby switching from the second configuration relationship to the third configuration relationship.

[0056] exist Fig.11 In the figure, the upper cover 2 is omitted for convenience of description. In the third configuration relationship, the surface of the first rod body 30 facing the first protrusion 12 abuts against the positioning surface SP13 of the first protrusion 12, and the connection between the first rod body 30 and the second rod body 32 (i.e., the pivot point P) is fixed at the default position P3 along with the fixing button 5. In addition, the surface of the second rod body 32 facing the first protrusion 12 abuts against the positioning surface SP14 of the first protrusion 12. Through the configuration of the positioning surface SP13, the positioning surface SP14, the first auxiliary groove 181, the second auxiliary groove 182, and the fixing groove 103, the first rod body 30 and the second rod body 32 can be stably supported in various operating conditions without changing the relative position relationship of the first mark 41, the second mark 42, the third mark 43, and the fourth mark 44.

[0057] It should be noted that when the connecting rod assembly 3 is fixed, the multiple virtual line segments formed by the marks 4 connected to each other meet certain conditions so that the optical system can identify different surgical instruments according to the above-mentioned first to third configuration relationships. The following is an explanation using the optical recognition system of Northern Digital Inc. (NDI) as the positioning basis. Among them, the various surgical instruments used in the optical recognition system in the navigation surgery need to be combined with different dynamic reference frames (DRF) for the optical system to identify.

[0058] The design of DRF is based on the principle of arranging the above-mentioned marks 4 (e.g., reflective balls) in the same plane. The arrangement must comply with NDI's DRF design rules (e.g., Polaris Tool Design Guide 10005896R02), including the following conditions:

[0059] Condition 1: The lengths of the virtual line segments are all greater than a first predetermined length;

[0060] Condition 2: The length difference between any two of the virtual line segments is greater than a second predetermined length;

[0061] Condition 3: The angle between any two virtual line segments is greater than a predetermined angle.

[0062] Among them, condition 1 is a necessary condition, and either condition 2 or condition 3 can be satisfied. In other words, if the length difference between the two virtual line segments is less than the second predetermined length, the angle between the two virtual line segments is greater than the predetermined angle. Conversely, if the angle between the two virtual line segments is less than the predetermined angle, the length difference between the two virtual line segments must be greater than the second predetermined length.

[0063] In this embodiment, the first predetermined length is in the range of 30 cm to 60 cm, the second predetermined length is in the range of 2 cm to 5 cm, and the predetermined angle is in the range of 1 degree to 5 degrees. In a preferred embodiment, in order to enable more accurate identification, the first predetermined length is in the range of 45 cm to 55 cm, for example, 50 cm, the second predetermined length is in the range of 3 cm to 4 cm, for example, 3.5 cm, and the predetermined angle is in the range of 3 degrees to 4 degrees, for example, 2 degrees.

[0064] Please refer to Figure 12 to Figure 14 , which are schematic diagrams of virtual line segments formed by the marks in the first to third configuration relationships of the embodiments of the present invention. Figure 6 In the first configuration relationship shown in FIG. 1 , the first mark 41, the second mark 42, the third mark 43 and the fourth mark 44 and the virtual line segments L1, L2, L3, L4, L5 and L6 can be drawn as shown in FIG. Fig.12 As shown, the first mark 41 is connected with the second mark 42 to form a virtual line segment L1, the second mark 42 is connected with the fourth mark 44 to form a virtual line segment L2, the third mark 43 is connected with the fourth mark 44 to form a virtual line segment L3, the first mark 41 is connected with the third mark 43 to form a virtual line segment L4, the first mark 41 is connected with the fourth mark 44 to form a virtual line segment L5, and the second mark 42 is connected with the third mark 43 to form a virtual line segment L6.

[0065] In the first configuration relationship, the lengths of the virtual line segments L1, L2, L3, L4, L5 and L6 are 117, 81, 51, 57, 97 and 109 respectively. The lengths of the virtual line segments are all greater than condition 1 of the first predetermined length and condition 2 of the length difference between any two of the virtual line segments is greater than the second predetermined length. Therefore, the DRF design rules of NDI are met.

[0066] In the second configuration relationship, the lengths of the virtual line segments L1, L2, L3, L4, L5 and L6 are 113, 87, 51, 69, 97 and 119 respectively. The lengths of the virtual line segments are all greater than condition 1 of the first predetermined length and the length difference between any two of the virtual line segments is greater than condition 2 of the second predetermined length. Therefore, the DRF design rules of NDI are met.

[0067] In the third configuration relationship, the lengths of the virtual line segments L1, L2, L3, L4, L5 and L6 are 80, 87, 51, 69, 93 and 108 respectively. The lengths of the virtual line segments are all greater than condition 1 of the first predetermined length and condition 2 of the length difference between any two of the virtual line segments is greater than the second predetermined length. Therefore, the DRF design rules of NDI are met.

[0068] In addition, the above-mentioned first to third configuration relationships need to be coordinated with the configuration adjustment of the first groove 10, the second groove 20, the first auxiliary groove 181, the second auxiliary groove 182 and the connecting rod group 3. Taking the first groove 10 and the corresponding second groove 20 as an example, when three sets of configuration relationships are required, the first groove 10 can be as follows: Figure 3 As shown, it is formed by connecting two straight grooves in different directions, thus providing three anchoring locations, and the second groove 20, the first auxiliary groove 181 and the second auxiliary groove 182 can be designed to have grooves with similar morphology. It can be imagined that when four sets of configuration relationships are required, the first groove 10 (for example, lightning shape) can be connected by four straight grooves extending in different directions, thus providing four anchoring locations, and so on, the configuration of the first groove 10, the second groove 20, the first auxiliary groove 181, the second auxiliary groove 182 and the connecting rod group 3 can be designed according to the number of required configuration relationships, so that a single adjustable marking reference device D can be converted into multiple sets of DRFs with different configurations.

[0069] In addition, although not specifically illustrated, the adjustable marking reference device D provided by the present invention can fix the surgical instrument to the surface of the base 1 or the upper cover 2 that does not face the connecting rod assembly 3, and the present invention does not limit its fixing method. For example, after being combined with the surgical instrument through an adapter that is compatible with the shape of the surgical instrument, the adjustable marking reference device D can be used to allow the optical recognition system to identify the surgical instrument connected thereto.

[0070] [Beneficial Effects of Embodiments]

[0071] One of the benefits of the present invention is that the adjustable marking reference device provided by the present invention can be converted into multiple sets of DRFs with different configurations as a single device. The user only needs to set different configurations for the surgical instruments to be used, without having to prepare a large number of DRFs with different configurations, thereby effectively reducing the number of DRF devices required.

[0072] In addition, through the configuration of positioning surfaces, auxiliary grooves and fixing grooves, the connecting rod group can be firmly supported in various operating conditions without changing the relative position relationship of the marks, and each configuration complies with NDI's DRF design rules.
