Description

Technical Field

[0001] The utility model belongs to the field of surgical instruments, in particular to an implant transportation device. Background Art

[0002] Bioconstructs are a range of biologically derived implants used to promote tissue growth, patch and repair tissue defects and tears. These implants include the repair of arthritic cartilage, the bonding of tendons to bones, and the bridging of degenerated rotator cuffs in the shoulder.

[0003] Some common bioconstructs and transplant materials include: platelet-rich fibrin membranes: used to promote wound healing and tissue repair; acellular allogeneic dermal grafts: used for skin defect repair; xenograft materials: used for bone and soft tissue repair. These implants have been able to reconstruct and treat musculoskeletal injuries and lesions that were previously untreatable and irreparable. For sheet-shaped implants, existing devices mostly use a push rod shaft with an elastically expandable deployment arm to transport and deploy the sheet-shaped implant within the channel.

[0004] In the process of realizing the utility model, the inventor discovered that there are at least the following problems in the prior art: the sheet-like implant is transported within the channel by means of an elastically expandable unfolding arm, and after it detaches from the push rod shaft, it automatically unfolds by releasing the elastic force, and cannot be actively controlled. At the same time, the automatic unfolding by releasing the elastic force is completed instantly, which can easily cause damage to the implant.

[0005] In view of the above problems, an implant transport device is now proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] The present application discloses an implant transport device, which is suitable for transporting and deploying sheet-shaped implants. By effectively controlling the movement of the insertion deployment rod, accurate transport and deployment of sheet-shaped implants are achieved, thereby solving the problem of sheet-shaped implants being easily damaged and difficult to control during transportation in the prior art.

[0028] The implant transport device comprises a handheld portion and two insertion and deployment rods, the two insertion and deployment rods being a left insertion and deployment rod and a right insertion and deployment rod. Each insertion and deployment rod is composed of an expansion section, a bending section and a connecting extension section, wherein the axes of the expansion section and the connecting extension section are parallel to each other and connected to the bending section through a rounded transition. A first tensioning mounting hole is provided at the distal end of the insertion and deployment rod, and a second tensioning mounting hole is provided at the proximal end.

[0029] Sutures are arranged at the four corners of the sheet implant, and the sutures are passed through the first and second tensioning installation holes respectively to tighten the sheet implant by pulling the sutures. An adjustment module is installed on the handheld part to adjust the angle of the insertion deployment rod so as to control the deployment state of the sheet implant. The adjustment module completes the adjustment by directly applying torque to the insertion deployment rod or by adjusting the knob.

[0030] Specific as Figure 1-Figure 5 As shown, the device comprises a handheld portion 2, on which two insertion and deployment rods 1 symmetrically arranged are movably mounted, and the two insertion and deployment rods 1 are respectively a left insertion and deployment rod 10 and a right insertion and deployment rod 20;

[0031] The insertion deployment rod 1 is composed of a deployment section 101, a curved section 102, and a connecting extension section 103 from the distal end to the proximal end. The axes of the deployment section 101 and the connecting extension section 103 are parallel to each other. The deployment section 101 and the connecting extension section 103 are transitioned with the curved section 102 through rounded corners. A hole 1001 is provided at the distal end of the deployment section 101, and a second tensioning installation hole 1002 is provided at the proximal end of the deployment section 101.

[0032] The handheld part 2 is provided with an adjustment module for adjusting the angle of the insertion and deployment rod 1. The adjustment angle of the insertion and deployment rod 1 is 0°-90°.

[0033] The specific operation steps of this device are as follows:

[0034] First, adjust the two insertion and deployment rods 1 to the open position, at which time the deployment sections 101 on the left insertion and deployment rod 10 and the right insertion and deployment rod 20 are in a position away from each other; Figure 6 As shown, the sheet implant 9 is arranged between two unfolding sections 101, and sutures are arranged at the four corners of the sheet implant 9. The sutures pass through 1001 and the second tensioning installation hole 1002 respectively to tighten the sheet implant 9 by pulling the sutures;

[0035] The adjustment module adjusts the two insertion and deployment rods 1 to the folded position, at which time the deployment sections 101 on the left insertion and deployment rod 10 and the right insertion and deployment rod 20 are in a mutually close position, and this position is set to an angle of 0°. At this time, the sheet implant 9 fixed by sutures is in a folded state, and the insertion and deployment rods 1 and the sheet implant 9 in this state are transported through the channel to the area where the operation is required;

[0036] The two insertion and deployment rods 1 are adjusted to the open position by the adjustment module, at which time the expansion sections 101 on the left insertion and deployment rod 10 and the right insertion and deployment rod 20 are at a position away from each other, and the left insertion and deployment rod 10 and the right insertion and deployment rod 20 are respectively rotated 90° and -90° relative to the folded position, so that the sheet-like implant 9 is spread out for easy operation;

[0037] After the operation is completed, the two insertion and deployment rods 1 are adjusted to the folded position through the adjustment module, and the insertion and deployment rods 1 are taken out through the passage.

[0038] In some embodiments, the insertion and deployment rod 1 can be made of a stainless steel tube with a diameter of 2-4 mm, the horizontal distance between the axis of the deployment section 101 and the connecting extension section 103 is 8-30 mm, preferably 3 mm in diameter, and the horizontal distance between the axis of the deployment section 101 and the connecting extension section 103 is 15 mm. The handheld portion 2 is processed by injection molding.

[0039] In some disclosures, a deployment rod mounting hole 201 is provided on the hand-held portion 2, and the inserted deployment rod 1 is movably installed in the deployment rod mounting hole 201. An axial fixing block mounting hole 202 is provided at the proximal end of the deployment rod mounting hole 201, and an axial fixing block 5 is installed in the axial fixing block mounting hole 202. The proximal end of the inserted deployment rod 1 is movably installed in the axial fixing block 5. The installation of the inserted deployment rod 1 and the axial fixing block 5 can be carried out by means of a rotating bearing and an annular groove, so that it can be ensured that the inserted deployment rod 1 can be axially fixed and can rotate freely at the same time.

[0040] In some disclosures, the adjustment module includes an adjustment slider 4, on which two adjustment through holes 401 are provided for inserting the deployment rod 1, and a conflicting adjustment block 402 is provided in the adjustment through hole 401;

[0041] A spatial cam groove 104 is provided on the outer side of the connecting extension section 103, and the spatial cam groove 104 includes a spiral groove 106. The two ends of the spiral groove 106 are respectively provided with a first straight groove 105 and a second straight groove 107. The first straight groove 105 and the second straight groove 107 are connected to the spatial cam groove 104 through a rounded transition, and the interference adjustment block 402 is movably installed in the spatial cam groove 104.

[0042] When the adjustment slider 4 is located in the first linear groove 105, the two insertion and deployment rods 1 are in the folded position, and when the adjustment slider 4 is located in the first linear groove 105, the two insertion and deployment rods 1 are in the open position. The lengths of the first linear groove 105 and the second linear groove 107 are greater than the adjustment slider 4 to ensure the stability of the insertion and deployment rods 1 after the positions are adjusted. In this way, the adjustment through hole 401 slides in the spatial cam groove 104 to drive the rotation of the insertion and deployment rods 1 by changing the movement of the adjustment slider 4 on the connecting extension section 103. When the adjustment slider 4 moves from the first linear groove 105 to the second linear groove 107, the left insertion and deployment rod 10 and the right insertion and deployment rod 20 rotate 90° clockwise and counterclockwise, respectively.

[0043] A slider mounting groove 203 is installed on the hand-held part 2. The adjustment slider 4 is movably installed in the slider mounting groove 203. A pushing block safety groove 204 is provided above the slider mounting groove 203. A pushing slider 3 is installed in the pushing block safety groove 204. The pushing slider 3 is fixedly connected to the adjustment slider 4. In this way, the movement of the adjustment slider 4 is completed by pushing the pushing slider 3. Furthermore, a positioning boss 205 is provided on the side of the pushing block safety groove 204, and a positioning groove cooperating with the positioning boss 205 is provided on the side of the pushing slider 3 to ensure the sliding stability of the pushing slider 3.

[0044] It should be noted that the rotation adjustment of the left insertion deployment rod 10 and the right insertion deployment rod 20 is linear, so that the opening angle of the deployment section 101 can be flexibly rotated according to needs during operation.

[0045] In some embodiments, a plurality of circumferentially distributed spatial cam grooves 104 are provided on the outer side of the connecting extension section 103, so that the force can be driven at multiple points to ensure the stability of the adjustment slider 4 driving the insertion deployment rod 1. Preferably, 2 to 3 spatial cam grooves 104 are provided, so that the force can be stable and the side wall can be prevented from being too thin due to too many spatial cam grooves 104.

[0046] In some embodiments, the adjustment module completes the adjustment by directly applying torque to the insertion and deployment rod 1. The specific method is to set an adjustment knob at the proximal end of the connecting extension section 103. Furthermore, the left insertion and deployment rod 10 and the right insertion and deployment rod 20 are provided with mutually meshing gears, so that the left insertion and deployment rod 10 and the right insertion and deployment rod 20 can be synchronously adjusted by an adjustment knob.

[0047] In some embodiments, a third tensioning mounting hole 1003 is provided at the rounded transition position between the curved section 102 and the unfolded section 101, so that traction and tensioning are performed through 1001 and the third tensioning mounting hole 1003. Through such a design, the inclined pulling of the suture at the position of the third tensioning mounting hole 1003 can ensure that the sheet implant 9 can be tensioned in both horizontal and vertical directions to ensure the tensioned state of the sheet implant 9 and ensure the operating effect.

[0048] In some embodiments, the hand-held portion 2 is provided with sword-shaped arc-shaped bosses 210 on both sides, and the arc-shaped bosses 210 on both sides are provided with a first suture fixing seam 2101, a second suture fixing seam 2102, a third suture fixing seam 2103 and a fourth suture fixing seam 2104 in sequence, so that the sutures on the sheet implant 9 can be inserted into the suture fixing seams for fixation.
