Definitions
- Support device for an implantable thread construction, system and measuring method with such a support device and manufacturing method for a support device
- 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 carrying the implantable thread configuration.
- Implantable thread constructions are required to fix a ligament or tendon transplant in a desired position.
- it can be a cruciate ligament transplant that needs to be positioned and fixed accordingly.
- Implantable thread constructions that have a holding element (“button”) and threads are known from the prior art.
- 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 through a drill channel in a bone into a holding position in which the holding element rests against the bone and holds the thread construction and thus the transplant.
- One of these known thread constructions is disclosed, for example, in WO 2017/207027 A1.
- the Thread construction In order to set the required lengths or drilling depths for the drilling channel and the blind hole and to configure the thread construction accordingly, the Thread construction must be measured. A tendon board is required for pre-configuration and for measuring the thread construction. In addition, the distance (“flip distance”) by which the holding element of the thread construction must be guided out of the drilling channel in order to pivot (“flip”) the holding element must be added manually to the desired drilling depth by the operating room staff or the surgeon himself.
- 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.
- the thread construction together with the transplant can be measured directly on the carrier device. This eliminates the need for a tendon board in the operating room.
- the handling and preparation of the thread construction including the transplant are made considerably easier with the carrier device according to the invention and the susceptibility to errors is reduced.
- 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 one after the other in the longitudinal direction of the carrier 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.
- the first measuring scale and the second measuring scale can have a predetermined distance from each other in the longitudinal direction of the carrier device.
- the lengths measured with the first measuring scale and the second measuring scale can be increased by a predetermined length amount by a predetermined distance. These measured lengths increased by the length of the predetermined distance can prevent damage to the soft tissue, which can occur, for example, if too much pressure is exerted on the soft tissue surrounding the drill hole via the holding element in the holding position described at the beginning.
- the second measuring scale and the second positioning device can be arranged on the carrier device in such a way that a predetermined distance is established between the second measuring scale and the second positioning device in the longitudinal direction of the carrier 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 at the beginning 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 has to be added to the second measured length by the operating room staff, which can prevent errors.
- 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 construction in a predetermined position on the carrier device.
- the positioning projection can have a front side and a back side.
- the positioning projection can be designed such that the holding element of the thread construction can be supported on the back side of the positioning projection.
- the back side of the positioning projection can face away from the first positioning device.
- the positioning projection can have an opening for passing through the threads of the thread construction.
- the positioning projection can be slotted.
- the slot of the positioning projection can be used to insert the threads of the thread construction into the opening of the positioning projection. This can make it easier to attach the thread construction to the carrier device and also to position the holding element on the positioning projection.
- the carrier device can have at least one tab.
- the at least one tab can be displaceable relative to the support body and can be connected to it in order to form the receiving area.
- 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 designed with two tab arms. The free ends of the tab arms can be inserted into the slot or the insertion window.
- the support device can be made of plastic.
- the first positioning device can define a connection position for the transplant with the implantable thread construction.
- the connection between the transplant and the thread construction can be made in the area of the receiving opening on the first positioning device.
- the first positioning device can set such a course of the thread construction that a connection section of the thread construction is formed for connection to the transplant.
- the The holding element of the thread construction can be located on the second fastening device. In the starting 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.
- the measurement procedure may include the following step:
- the first positioning device 36 is arranged at a predetermined position relative to the first measuring scale 16.
- the first positioning device 36 defines a first predetermined position for the connection of the thread construction to a transplant.
- 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 transplant is positioned at the zero value of the first measuring scale 16.
- 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.
- 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 were 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 on the front of the support body 12.
- the front of the support body 12 and 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 on the front of the support body 12.
- Figure 3 shows a perspective view of a system 100 comprising the carrier device 10 and a suture construction 102.
- the system 100 forms a 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 transplant and for pre-configuration and measurement.
- the thread construction 102 is attached to the support body 12.
- the first positioning device 36 and the second positioning device 38 position the thread construction 102 in a predetermined position on the support body 12.
- the thread construction 102 is placed with its loop-shaped section around the two positioning elements 40, 42 of the first positioning device 36. Starting from the first positioning device 36, the thread construction 102 extends in the direction of the second positioning device 38.
- the thread construction 102 is inserted into the opening 46 of the positioning projection 44 via the slot 48 in the positioning projection 44. In the state shown in Figure 3, the thread construction 102 extends through the opening 46 in the positioning projection 44.
- the thread construction 102 has a holding element 104, which is 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 passage opening 34 into the receiving area AB on the rear side of the support body 12.
- the ends 30, 32 of the tab arms 26, 28 are shown, which protrude through the insertion window 24.
- the thread construction 102 is laid in a loop shape 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 passage opening 34 into the receiving area AB.
- the positioning elements 40, 42 of the first positioning device 36 redirect the thread construction 102 such that a section 106 of the thread construction 102 extends between the positioning elements 40, 42 and spans the receiving opening 50 in this area.
- the section 106 of the thread construction 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 construction and connected to the thread construction 102.
- the thread construction 102 runs in section 106 essentially orthogonal to the longitudinal direction L of the carrier device 10.
- Figure 4 shows a perspective view of the system 100 with a transplant 108 connected to the thread construction 102.
- the transplant 108 was placed through the receiving opening 50 around the connecting section 106 of the thread construction 102 and connected to the thread construction 102.
- the thread construction 102 is guided around the positioning elements 40, 42 such that the thread construction 102 runs along the back of the positioning elements 40, 42.
- a first length can be determined using the first measuring scale 16.
- the first length can be, for example, the length or drilling depth of a femoral blind hole.
- the determined first length is removed from the transplant 108. This is shown in Figure 4 as an example by the dashed line LT.
- the determined first length LT can be, for example, 20 mm.
- the thread construction 102 is released from the first positioning device 36 and thus from the positioning elements 40, 42.
- a relative movement of the loop-shaped section of the thread construction 102 together with the transplant is carried out relative to the positioning projection 44 of the second positioning device 38.
- the holding element 104 of the thread construction 102 is supported on the rear side 44b of the positioning projection 44 during this relative movement.
- a second length can now be determined using the second measuring scale 18. This state is shown in Figure 5.
- the tab 20 was released from the support body 12 and the receiving area AB was opened.
- the threads of the thread construction 102 can be actuated, 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 construction 102 can be changed.
- the second length can thus be set in relation to the second measuring scale 18.
- 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.
- 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 that is suitable for contact with the bone.
- the holding element 104 In order to provide sufficient space for pivoting
- the holding element 104 (“flipping”) able to pivot, 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 able to pivot.
- the addition of the flipping distance to the second length by the operating room staff or the surgeon, as described at the beginning, is therefore no longer necessary. Errors can thus be avoided with the carrier device 10.
