Description

[0001] Support device for an implantable thread construction, system and measuring method with such a support device and manufacturing method for a support device

[0002] The present invention relates to a carrier device for an implantable thread construction and to a system comprising such a carrier device and an implantable thread construction. Furthermore, the present invention relates to a manufacturing method for a carrier device and a measurement method for preconfiguring an implantable thread construction.

[0003] Support devices for implantable thread constructions are known from the prior art. The implantable thread construction is attached to the support device. The known support devices are intended exclusively for supporting the implantable thread configuration.

[0004] Implantable thread constructs are required to fix a ligament or tendon transplant in a desired position. For example, it may be a cruciate ligament transplant that must be positioned and fixed accordingly. Implantable thread constructs are known from the prior art, which have a holding element ("button") and threads. The threads are connected to the holding element and can control the position of the holding element. The holding element can be pivoted ("flipped") via the threads, for example, from an insertion position for guiding it through a drill channel in a bone into a holding position in which the holding element rests against the bone and holds the thread construct and thus the transplant. One of these known thread constructs is disclosed, for example, in WO 2017 / 207027 A1.

[0005] These suture constructs must be pre-configured and measured by the operating room staff prior to transplantation. Pre-configuring the suture construct reduces friction between the suture construct's threads and the graft, thus avoiding unnecessary stress on the graft. For example, in the case of a cruciate ligament graft, pre-configuration can also reduce friction between the suture construct's threads and the femoral condyle, preventing damage to the condyle.

[0006] In order to set the required lengths and drilling depths for the drill channel and the blind hole and to configure the suture construct accordingly, the suture construct must be measured. A tendon board is required for pre-configuration and measuring of the suture construct. Furthermore, the distance (the "flip distance") by which the holding element of the suture construct must be extended out of the drill channel in order to pivot ("flip") the holding element must be manually added to the desired drilling depth by the operating room staff or the surgeon.

[0007] Based on this prior art, it is an object of the present invention to simplify the preconfiguration and measurement of the thread construction.

[0008] This object is achieved with a carrier device for an implantable thread construction according to patent claim 1, a system according to patent claim 16 and a measuring method according to patent claim 21.

[0009] The carrier device has at least one support body for attaching the implantable thread construction and at least one measuring device which is arranged on the support body and is designed to measure the implantable thread construction.

[0010] With the integrated measuring device of the carrier device, the suture construct can be measured together with the graft directly on the carrier device. This eliminates the need for a tendon board in the operating room. The handling and preparation of the suture construct including the graft are significantly simplified with the carrier device according to the invention, and the susceptibility to errors is reduced.

[0011] The at least one measuring device can have a first measuring scale and a second measuring scale. The first measuring scale and the second measuring scale can be arranged consecutively in the longitudinal direction of the support device. The first measuring scale and the second measuring scale can be provided for measuring a first length (first measuring scale) and a second length (second measuring scale). The first measuring scale and the second measuring scale can indicate millimeters as the unit of length.

[0012] The first measuring scale and the second measuring scale can be spaced apart by a predetermined distance in the longitudinal direction of the support device. With this predetermined distance, the lengths measured with the first measuring scale and the second measuring scale can be increased by a predetermined amount. These measured lengths, increased by the length of the predetermined distance, can prevent damage to the soft tissue, which can occur, for example, if excessive pressure is exerted on the soft tissue surrounding the drill hole via the holding element in the holding position described above.

[0013] The at least one support device can have a first positioning device and a second positioning device for positioning the implantable thread construction on the support body. The first positioning device and the second positioning device can be offset from one another in the longitudinal direction of the support device.

[0014] The first positioning device can be arranged at a predetermined position relative to the first measuring scale in the longitudinal direction of the support device. The first positioning device can be arranged at the zero value of the first measuring scale. The at least one second positioning device can be arranged at a predetermined position relative to the second measuring scale. The second positioning device can be arranged at the zero value of the second measuring scale.

[0015] The second measuring scale and the second positioning device can be arranged on the support device such that a predetermined distance is established between the second measuring scale and the second positioning device in the longitudinal direction of the support device. The at least one predetermined distance can be determined based on the shape and / or dimensions of a holding element of the thread construction. The predetermined distance can correspond to the distance explained above that is required to pivot ("flip") the holding element into a holding position on the bone. This distance can also be referred to as the "flip distance." The "flip distance" therefore no longer needs to be added to the second measured length by the operating room staff, which can prevent errors.

[0016] The first positioning device can have at least two positioning elements. The positioning elements can be designed to deflect the implantable thread construction. The positioning elements can be elements around which the thread construction can be wrapped. The positioning elements can be designed such that the thread construction runs between the positioning elements substantially orthogonal to the longitudinal axis of the support device.

[0017] The second positioning device can have at least one positioning projection. The positioning projection can be designed to position the holding element of the thread structure in a predetermined position on the support device. The positioning projection can have a front side and a rear side. The positioning projection can be designed such that the holding element of the thread structure can be supported on the rear side of the positioning projection. The rear side of the positioning projection can face away from the first positioning device.

[0018] The first positioning device can define a connection position for the graft to the implantable thread construction. The second positioning device can adjust the position of the graft relative to the holding element of the thread construction. When the implantable thread construction is located on the first positioning device and the second positioning device, i.e., in the starting position on the support device, the distance between the graft attached to the thread construction and the holding element can correspond to the longitudinal distance between the first positioning device and the second positioning device.

[0019] The positioning projection can have an opening for the threads of the thread construction to pass through. The positioning projection can be slotted. The slot of the positioning projection can serve to insert the threads of the thread construction into the opening of the positioning projection. This can facilitate the attachment of the thread construction to the support device and also the positioning of the holding element on the positioning projection.

[0020] The support device can have at least one receiving opening. The at least one receiving opening can be arranged between the at least two positioning elements of the first positioning device. A transplant for connection to the thread construction can be inserted into the receiving opening. The receiving opening can extend from the first positioning device in the direction of the second positioning device into the support body. The receiving opening can widen in the transverse direction along the longitudinal direction of the support device. This makes it possible to set an elasticity of the support device in the region of the receiving opening, which can facilitate the release of the thread construction from the first positioning device. The positioning elements of the first positioning device can be designed such that the thread construction spans the receiving opening.

[0021] A graft can be placed through the receiving opening around the portion of the suture construct that extends between the two positioning elements for connection to the suture construct. The portion of the suture construct that extends between the two positioning elements can form a connecting portion for connecting the graft to the suture construct.

[0022] The support device can have at least one receiving area for threads of the thread construction. The receiving area can be formed on the rear side of the support body.

[0023] The support device may have at least one tab. The at least one tab may be displaceable relative to the support body and connectable to it to form the receiving area.

[0024] The flap can be folded over along one edge of the carrier body. This edge can be referred to as a "folding edge." The flap can be folded toward the back of the carrier body and connected to the carrier body with its free end. This creates a pocket on the back of the carrier body for the threads of the thread construction.

[0025] The support body can have at least one slot or insertion window into which the tab can be inserted with its free end. The tab can be formed with two tab arms. The free ends of the tab arms can be inserted into the slot or insertion window.

[0026] At least one of the tab arms can have an opening to which the ends of the threads can be secured. The ends of the threads can be secured to this opening in the open and / or closed state of the receiving area.

[0027] The support device can have at least one through-opening for the threads of the thread construction. The threads of the thread construction can be guided from the front of the support body to its rear through the through-opening. The through-opening can be formed at the transition between the support body and the tab. The threads can be guided into or out of the receiving area through the through-opening.

[0028] At least the at least one measuring device can be formed integrally with the at least one support body. The tab can also be formed integrally with the support body. The entire support device can be formed integrally.

[0029] The support device can be made of plastic.

[0030] The system according to the invention comprises a carrier device of the type described above and a thread construction attached to the support body of the carrier device.

[0031] The system can be treated as a single unit. The system, including the carrier device and the attached suture construct, can be distributed as a single unit and used in the operating room. No additional components or equipment are required for preconfiguration, as the carrier device is designed not only to support the suture construct, but also to measure and preconfigure the suture construct with the graft.

[0032] The first positioning device and the second positioning device can position the implantable thread construction in a predetermined position on the support body. A holding element of the thread construction is supported on the second positioning device, and threads of the thread construction are received in the receiving area of ​​the support device.

[0033] A manufacturing method for producing a carrier device for an implantable thread construction comprises the following steps:

[0034] - Providing a plate-shaped base body, and

[0035] - Producing the support body of the support device from the plate-shaped base body, wherein the first positioning device, the second positioning device, the at least one tab, and the at least one measuring device are formed on the support body in a single operation. The support device can be manufactured quickly and easily with just a few process steps. Since the support device is manufactured from a base body using the manufacturing process, the support device has a simple structure without loose individual parts.

[0036] The manufacturing process may include the following step:

[0037] - Applying the first measuring scale and the second measuring scale to the support body.

[0038] The first and second measuring scales can be printed or stamped onto the support body. Alternatively, the first and second measuring scales can be embossed into the support body.

[0039] The support body of the support device can be manufactured using a stamping process. The entire support device can be manufactured using a stamping process. This means that the support body and the tab connected to the support body can be stamped out of a base body. By folding and / or unfolding, the individual elements of the support device can be brought into their predetermined position and / or orientation. Furthermore, elements such as the edge of the tab can also be embossed into the base body during the stamping process.

[0040] A measurement procedure for preconfiguring an implantable suture construction using the system described above comprises the following steps:

[0041] - Attaching a transplant to the thread construction in the area of ​​the receiving opening of the carrier device,

[0042] - Determining a first length using the first measuring scale;

[0043] - Setting a second length by actuating the thread construction, wherein a section of the thread construction together with the transplant is displaced relative to the second positioning device in accordance with the second measuring scale and the determined first length.

[0044] The first positioning device can define a connection position for the transplant to the implantable thread construction. The connection between the transplant and the thread construction can be made in the region of the receiving opening on the first positioning device. The first positioning device can adjust the course of the thread construction such that a connecting section of the thread construction for connection to the transplant is formed. The holding element of the thread construction can be located on the second fastening device. In the initial position of the thread construction on the carrier device, the distance between the transplant attached to the thread construction and the holding element can correspond to the distance in the longitudinal direction between the first positioning device and the second positioning device.

[0045] With the suture construct and the attached graft in the initial position, the first length can be determined using the first measuring scale. The determined first length can be removed from the graft with reference to the first measuring scale. After removing the first length from the graft, the suture construct can be removed from the first positioning device.

[0046] To adjust the second length, the suture assembly is actuated. This changes the position of the graft relative to the second positioning device, where the holding element of the suture assembly is located. The movement of the graft due to the actuation of the suture assembly can essentially occur in the longitudinal direction of the support device. Once the second length has been adjusted according to the second measuring scale, the preconfiguration of the suture assembly with the graft and the measuring process are complete. Apart from the support device, no additional components or devices, such as a tendon board, were required for the preconfiguration and measuring.

[0047] The measurement procedure may include the following step:

[0048] - Opening the receiving area of ​​the carrier device to operate the thread construction to adjust the second length.

[0049] To open the receiving area, the free end of the support device's tab can be detached from the support body. This allows the tab to be opened and the threads to be released for operating the thread assembly.

[0050] The invention is explained below using exemplary figures. The drawings, the description, and the claims contain numerous features in combination. Those skilled in the art will expediently consider the features individually and use them in meaningful combination within the scope of the claims.

[0051] If there is more than one instance of a particular object, only one of them may be provided with a reference symbol in the figures and in the description. The description of this instance can be transferred accordingly to the other instances of the object. If objects are named using numerical terms, such as first, second, third object, etc., these serve to name and / or assign objects. Accordingly, for example, a first object and a third object, but not a second object, may be included. However, a number and / or sequence of objects could also be derived using numerical terms.

[0052] They represent:

[0058] Fig. 5 is a perspective view of the system according to Figure 3 with a transplant attached and with the receiving area open.

[0059] Figure 1 shows a perspective view of a support device 10 for an implantable thread construction (not shown in Figure 1). The support device 10 has a support body 12 to which the thread construction can be attached. A measuring device 14 is arranged on the support body 12. The measuring device 14 has a first measuring scale 16 and a second measuring scale 18. The first measuring scale 16 and the second measuring scale 18 are arranged consecutively in the longitudinal direction L of the support device 10. The first measuring scale 16 and the second measuring scale 18 are arranged on the support body 12 at a distance from one another in the longitudinal direction L of the support device 10. A predetermined distance a is thus established between the first measuring scale 16 and the second measuring scale 18. The first measuring scale 16 and the second measuring scale 18 extend along an edge of the support body 12 running in the longitudinal direction L.The first measuring scale 16 is arranged on a strip-shaped section of the support body 12.

[0060] The carrier device 10 has a flap 20 connected to the support body 12. The flap 20 can be displaced relative to the support body 12 to form a receiving area for threads of the thread construction. The flap 20 can be folded along a folding edge 22 toward the rear of the support body 12. The folding edge 22 can be a stamped edge to facilitate folding the flap 20. To form the receiving area, the flap 20 can be folded over and connected to the support body 12 by its free end. The support body 12 has an insertion window 24 for inserting the free end of the flap 20.

[0061] The tab 20 has two tab arms 26, 28 that extend away from the support body 12 in the longitudinal direction L of the carrier device 10. By folding the tab 20 at the folding edge 22, the free ends 30, 32 of the tab arms 26, 28 can be inserted into the insertion window 24 on the support body 12 to form the receiving area on the rear side of the support body 12. The free ends 30, 32 of the tab arms 26, 28 are inserted into the insertion window 24 from the rear side of the support body 12, thereby securing them to the support body 12.

[0062] The support device 10 further includes a through-opening 34. The through-opening 34 is formed partially on the support body 12 and partially on the tab 20. The through-opening 34 divides the folding edge 22. The through-opening 34 is formed approximately in the center of the folding edge 22. The threads of the thread construction can pass through the through-opening 34.

[0063] The carrier device 10 has a first positioning device 36 and a second positioning device 38, which are designed to position the implantable thread construction on the support body 12. The first positioning device 36 and the second positioning device 38 are offset from one another in the longitudinal direction of the carrier device 10. The first positioning device 36 and the second positioning device 38 are thus spaced apart by a predetermined distance in the longitudinal direction of the carrier device 10.

[0064] The first positioning device 36 has two positioning elements 40 and 42. The positioning elements 40, 42 are offset from one another in the transverse direction Q. The positioning elements 40 and 42 are designed such that they can guide and deflect threads of the implantable thread construction. The positioning elements 40, 42 can be designed as positioning lugs that protrude from the support body 12 in the longitudinal direction L of the carrier device 10. The positioning elements 40, 42 predetermine a predetermined course for the threads of the thread construction in the region of the first positioning device 36.

[0065] The second positioning device 38 has a positioning projection 44. An opening 46 extends through the positioning projection 44, through which the threads of the thread construction can be guided. The positioning projection 44 can be slotted. The threads can be inserted into or removed from the opening 46 through the slot 48. The positioning projection 44 has a front side 44a and a rear side 44b. A holding element (not shown in Figure 1) of the thread construction can be supported on the rear side 44b of the positioning projection 44.

[0066] The support device 10 has a receiving opening 50. The receiving opening 50 is formed on the support body 12. A transplant (not shown) can be guided through the receiving opening 50 in order to be connected to the thread construction. The receiving opening 50 extends between the two positioning elements 40 and 42 into the support body 12. The receiving opening 50 widens along the longitudinal direction L of the support device 10 in the transverse direction Q. Due to the widening receiving opening 50, an elasticity of the support device 10 can be achieved in the region of the receiving opening 50, which can facilitate the release of the thread construction from the first positioning device 36.

[0067] The first positioning device 36 is arranged at a predetermined position relative to the first measuring scale 16. The first positioning device 36 establishes a first predetermined position for connecting the thread construction to a graft. The first positioning device 36 positions the thread construction on the carrier device 10 such that a connecting section of the thread construction for connection to the graft is positioned at the zero value of the first measuring scale 16.

[0068] The second positioning device 38 is arranged at a predetermined position relative to the second measuring scale 18. The second positioning device 38 and the second measuring scale 18 are arranged on the support device 10 such that a predetermined distance D is established between the second measuring scale 18 and the second positioning device 38. The predetermined distance D is established between the positioning projection 44 and the zero value of the second measuring scale 18. The numerical values ​​of the second measuring scale 18 increase toward the first measuring scale 16.

[0069] The support device 10 is formed in one piece. The support device 10 can be manufactured from a plate-shaped base body by means of a stamping process. The above-described elements can be unfolded or folded into their predetermined position and orientation, if necessary.

[0070] The tab arm 28 of the tab 20 has an opening 52. The opening 52 can serve to fix the ends of the threads of the thread construction to the tab 20 or to the carrier device 10.

[0071] Figure 2 shows a perspective view of the carrier device 10 in which the tab 20 (see Figure 1) has been folded over towards the rear of the support body 12. The free ends 30, 32 of the tab arms 26, 28 have been inserted into the insertion window 24 from the rear of the support body 12. The free ends 30, 32 protrude through the insertion window 24 at the front of the support body 12. This forms the receiving area AB for the threads of the thread construction at the rear of the support body 12. The front of the support body 12 and of the carrier device 10 as a whole is defined by the first measuring scale 16 and the second measuring scale 18, i.e. the first measuring scale 16 and the second measuring scale 18 are located at the front of the support body 12.

[0072] Figure 3 shows a perspective view of a system 100 comprising the carrier device 10 and a suture structure 102. The system 100 forms a single unit. This unit can be packaged and distributed in the state shown in Figure 3. In the operating room, this unit can be unpacked and is ready for use without additional components for connection to a graft, as well as for preconfiguration and measurement.

[0073] The thread structure 102 is attached to the support body 12. The first positioning device 36 and the second positioning device 38 position the thread structure 102 in a predetermined position on the support body 12. The loop-shaped portion of the thread structure 102 is wrapped around the two positioning elements 40, 42 of the first positioning device 36. Starting from the first positioning device 36, the thread structure 102 extends toward the second positioning device 38. The thread structure 102 is inserted into the opening 46 of the positioning projection 44 via the slot 48 in the positioning projection 44. In the state illustrated in Figure 3, the thread structure 102 extends through the opening 46 in the positioning projection 44.

[0074] The thread construction 102 has a holding element 104, also referred to as a "button." The holding element 104 is supported on the rear side 44b of the positioning projection 44. The thread construction 102 extends through the through-opening 34 into the receiving area AB on the rear side of the support body 12. On the front side of the support body 12 in Figure 3, the ends 30, 32 of the tab arms 26, 28 are shown, which protrude through the insertion window 24. In other words, the thread construction 102 is looped around the positioning elements 40, 42 and guided through the opening 46 of the positioning projection 44, so that the holding element 104 of the thread construction 102 can be supported on the positioning projection 44. The threads of the thread construction 102 are guided through the through-opening 34 into the receiving area AB.

[0075] The positioning elements 40, 42 of the first positioning device 36 redirect the thread structure 102 such that a section 106 of the thread structure 102 extends between the positioning elements 40, 42 and spans the receiving opening 50 in this area. The section 106 of the thread structure 102 forms a connecting section to which a transplant (not shown in Figure 3) can be attached. The transplant can be placed through the receiving opening around the connecting section 106 of the thread structure and connected to the thread structure 102. The thread structure 102 extends in section 106 essentially orthogonal to the longitudinal direction L of the support device 10.

[0076] Figure 4 shows a perspective view of the system 100 with a graft 108 connected to the suture structure 102. The graft 108 has been placed through the receiving opening 50 around the connecting section 106 of the suture structure 102 and connected to the suture structure 102. The suture structure 102 is guided around the positioning elements 40, 42 such that the suture structure 102 runs along the back of the positioning elements 40, 42. In the state of the system 100 and the graft 108 shown in Figure 4, a first length can be determined using the first measuring scale 16. The first length can, for example, be the length or drilling depth of a femoral blind hole. The determined first length is marked off the graft 108. This is illustrated in Figure 4 by way of example by the dashed line LT. The determined first length LT can, for example, be 20 mm.

[0077] Following the determination of the first length, the thread structure 102 is released from the first positioning device 36 and thus from the positioning elements 40, 42. Actuating the thread structure 102 causes a relative movement of the loop-shaped portion of the thread structure 102, together with the graft, relative to the positioning projection 44 of the second positioning device 38. During this relative movement, the holding element 104 of the thread structure 102 is supported on the rear side 44b of the positioning projection 44. A second length can now be determined using the second measuring scale 18. This state is shown in Figure 5.

[0078] To activate the thread structure 102, the tab 20 was released from the support body 12 and the receiving area AB was opened. By opening the receiving area AB, the threads of the thread structure 102 can be activated, whereby the relative position of the transplant 108 relative to the positioning projection 44 of the second positioning device 38 and thus to the holding element 104 of the thread structure 102 can be changed. This allows the second length to be adjusted relative to the second measuring scale 18.

[0079] Once the LT marking for the first length is at the desired position on the second measuring scale 18, the operation of the suture assembly 102 is terminated. The second length can, for example, indicate the length or drilling depth of the femoral canal. The second length can, for example, be 35 mm.

[0080] Due to the predetermined distance D between the second positioning device 38 and the zero value of the second measuring scale 18, no further length amount needs to be added to the second set length, since the predetermined distance D corresponds to the distance required to pivot or "flip" the holding element 104. The holding element 104 is guided through the femoral canal in an insertion position and must then be pivoted into a holding position suitable for contact with the bone. In order to have sufficient space for pivoting ("flip") the holding element 104, the holding element 104 must be moved a predetermined distance out of the femoral canal. The additional distance D corresponds to the flipping distance by which the holding element 104 must be moved out of the femoral canal in order to be pivoted. The addition of the flipping distance to the second length by the operating room staff or the surgeon, as described above, is therefore no longer necessary.The carrier device 10 can thus prevent errors.
