Description

Custom clamp device for talus implant gripping

[0001] The present invention relates to a clamp device, and in particular, to a custom clamp device for grasping a talus implant that can be used for the smooth insertion or removal of an artificial implant during surgery.

[0002] With the advancement of medical technology, various artificial implants have been developed, among which talus implants play a crucial role in restoring skeletal and joint function. Talus implants are primarily used to replace a talus that has lost its normal function due to fractures, arthritis, or severe injury. Since these implants must function with high precision within the human body, accuracy in size and shape is critical.

[0003] In the conventional talus implant insertion process, the 'talus sizer' was used as an essential tool. The talus sizer is a tool fabricated by mimicking the anatomical shape of the talus to determine the optimal implant size, and it plays a role in verifying the implant's fit with the surgical site during surgery.

[0004] Computed tomography (CT) can be utilized when designing talus implants. However, since it is difficult to verify cartilage using CT, it is currently challenging to design implants that take the cartilage condition into account.

[0005] More specifically, since the optimal implant size can vary depending on the condition of the cartilage remaining in the affected area, conventionally, multiple implants of different sizes were prepared, and a sizer with a handle was implanted first to determine the optimal size before implanting the corresponding size.

[0006] However, talus sizers have the disadvantage of requiring high production costs and significant time due to their complex structure, which includes handles and joints, and the need for precision similar to that of the original implant during the manufacturing process. In particular, talus sizers consume the same or more material as the implant and require additional time during the printing process.

[0007] Furthermore, the conventional method of implant insertion involved using a sizer to determine the optimal product size and then manually grasping and pushing the implant into the affected area. However, since talus implants have a smooth surface and a rounded shape, accidents involving slipping from the hands frequently occur during surgery. Such accidents can leave scratches on the surface of the implant, increasing the likelihood of residual contamination that is not removed during cleaning and disinfection. In particular, residual contamination increases the risk of postoperative infection, which can negatively impact the patient's recovery process.

[0008] Furthermore, conventional methods often required rotational movements while pushing the implant into the affected area. However, the process of manually rotating and inserting the implant required excessive force and presented limitations in terms of precise manipulation. This problem makes it difficult to locate the precise position of the implant, increases surgical time, and raises the risk of unnecessary tissue damage to the patient.

[0009] Accordingly, methods have been proposed to add a handle coupling structure to the implant itself or to assemble the implant using fixation devices such as screws during surgery. However, these methods have the disadvantage of reducing the structural safety of the implant and its stability with surrounding tissues because they require securing additional unnecessary space in the implant design. If deformations such as splitting or drilling screw holes are applied to create the assembly structure of the implant, the structural safety of the implant may be compromised, and it may affect the surface roughness and shape, potentially causing damage to surrounding articular surfaces or tissue structures.

[0010] Therefore, there has been a need for a specialized tool that can replace existing talus sizers without creating unnecessary space within the implant, while enabling safe and precise manipulation of the implant during surgery. Such a tool must facilitate the assessment of product suitability based solely on the implant itself, without the need for separate substitutes like sizers; it must also reduce the physical burden on the surgeon during application to the surgical site and minimize the risk of contamination. Furthermore, it must enhance efficiency during the manufacturing process to reduce the time and cost required for sizer production.

[0011] The problem to be solved is to provide a customized clamp device for grasping a talus implant according to one embodiment of the present invention, which can provide an efficient tool for the accurate manipulation and insertion of a talus implant.

[0049] FIG. 1 illustrates a custom clamp device for grasping a talus implant according to one embodiment of the present invention. FIG. 2 illustrates a gripper portion of a custom clamp device for grasping a talus implant according to one embodiment of the present invention. FIG. 3 is an exploded perspective view of a custom clamp device for grasping a talus implant according to one embodiment of the present invention. FIG. 4 is an exploded perspective view and a cross-sectional view of a gripper portion of a custom clamp device for grasping a talus implant according to one embodiment of the present invention.

[0050] Referring to FIGS. 1 to 4, a customized clamp device for grasping a talus implant according to one embodiment of the present invention will be described.

[0051] A custom clamp device (1) for gripping a talus implant according to one embodiment of the present invention may include a handle portion (100) provided to be gripped by a user, a clamp portion (300) coupled to the handle portion (100) to enable stable gripping of a talus implant, and a fastening cap (200) provided to accommodate a part of the clamp portion (300) and a part of the handle portion (100) to fix the clamp portion (300) to the handle portion.

[0052] The fastening method of the clamp portion (300) and the handle portion (100) described herein is merely an illustrative representation of one of several embodiments, and the present invention is not limited to said fastening method. Furthermore, various structures and methods may be applied to fasten the clamp portion (300) to the handle portion (100) in addition to the method described below.

[0053] The clamp portion (300) can be detachably coupled to the handle portion (100). The clamp portion (300) can be fixed to the handle portion (100) by the fastening cap (200). The specific method by which the fastening cap (200) fixes the clamp portion (300) to the handle portion (100) will be described later.

[0054] Meanwhile, the clamp portion (300) may include a clamp fastening portion (310) coupled to the handle portion (100) and a clamp gripping portion (320) extended from the clamp fastening portion (310) in a direction away from the handle portion (100) to grip a talus implant. The clamp fastening portion (310) may be received in the handle portion (100) and fixed by a fastening cap (200).

[0055] The above clamp portion (300) may include a first clamp (400) configured to support one side of the talus implant and a second clamp (500) configured to support the other side of the talus implant positioned opposite to the one side of the talus implant and gripping the talus implant together with the first clamp (400).

[0056] The talus implant can be firmly supported by the first forceps (400) and the second forceps (500). The first forceps (400) and the second forceps (500) can be custom-made to fit the shape of the talus implant. By custom-making the first forceps (400) and the second forceps (500) to fit the talus implant, there is an advantage in that a separate sizer does not need to be manufactured.

[0057] Since it allows for the smooth gripping of talus implants inserted into the actual body without the need for a separate sizer, it has the effect of saving costs and time required for sizer fabrication.

[0058] The first clamp (400) may include a first body (410) that is received and coupled to the handle portion (100), a first avoidance member (420) that extends from the first body (410) in a first avoidance direction that intersects the axial direction of the handle portion (100), a first bending member (430) that extends from the end of the first avoidance member (420) in a bent direction in the axial direction of the handle portion (100), a first branching member (440) that extends from the end of the first bending member (430) in a bent direction that intersects the axial direction of the handle portion (100) and supports one side of the talus implant, and a first supporting member (450) that extends from the end of the first branching member (440) in a bent direction that intersects the first branching direction and supports one side of the talus implant.

[0059] The first body (410) and the second body (510) can form the clamp fastening part (310). The first body and the second body (510) can be combined with each other to form the clamp fastening part (310).

[0060] Additionally, the second clamp (500) is formed with the first body (410) and comprises a second body (510) that is received and coupled to the handle portion (100), a second avoidance member (520) that extends from the second body (510) in a second avoidance direction that intersects the axial direction of the handle portion (100), a second bending member (530) that extends from the end of the second avoidance member (520) in a bent direction in the axial direction of the handle portion (100), a second branching member (540) that extends from the end of the second bending member (530) in a bent direction that intersects the axial direction of the handle portion (100) and supports the other side of the talus implant, and a second supporting member (540) that extends from the end of the second branching member (540) in a bent direction that intersects the second branching direction and supports the other side of the talus implant. It may include a second support member (550).

[0061] Additionally, the first avoidance member (420) and the second avoidance member (520) are arranged in close contact with each other, and the first bending member (430) and the second bending member (530) can be arranged in close contact with each other.

[0062] Additionally, the first bending member (430) and the second bending member (530) may be extended parallel to the axial direction of the handle portion, but spaced apart from the axial direction of the handle portion (100).

[0063] Additionally, the first avoidance direction and the second avoidance direction may be provided parallel to each other, and the first branching direction and the second branching direction may be provided in opposite directions with respect to the axial direction of the handle part (100).

[0064] The first avoidance direction and the second avoidance direction are parallel to each other and may intersect with the axial direction of the handle portion (100). Accordingly, the first avoidance member (420) and the second avoidance member (520) can separate the center of the gripper portion (300) from the central axis of the handle portion (100). Through this, when a surgeon performs talus implant surgery using the custom clamp device for grasping the talus implant, the surgeon can secure a field of view, thereby facilitating the surgery.

[0065] More specifically, the first avoidance member (420) and the second avoidance member (520) are arranged to be in close contact with each other by extending parallel to a direction intersecting the axial direction of the handle portion (100), and the first bending member (430) and the second bending member (530) can be arranged to be in close contact with each other by extending parallel to the axial direction of the handle portion (100) from the first avoidance member (420) and the second avoidance member (520), respectively. Due to the characteristics of such extension directions, there is an effect of minimizing obstruction of the user's view when checking the talus implant held by the clamp portion (300) while the user is holding the handle portion (100).

[0066] Additionally, the first branching direction and the second branching direction may be provided in directions opposite to each other with respect to the axial direction of the handle portion (100). That is, the first clamp (400) and the second clamp (500) may be arranged spaced apart from each other from the first branching member (440) and the second branching member (540). The first body (410) and the second body (510) of the first clamp (400) and the second clamp (500) may be joined together, the first avoidance member (420) and the second avoidance member (520) may be extended parallel to each other, and the first bending member (430) and the second bending member (530) may also be extended parallel to each other and be in close contact.

[0067] On the other hand, the first branch member (440) and the second branch member (540) can form a space capable of gripping a talus implant by extending in opposite first and second branch directions, respectively. The first support member (450) and the second support member (550) can again form a space capable of firmly supporting a talus implant by extending in directions that bring them closer together.

[0068] The first avoidance member (420), the first bending member (430), the first branching member (440), and the first support member (450) can all be extended in a direction away from the first body (410). The second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) can all be extended in a direction away from the second body (510).

[0069] That is, the first avoidance member (420), the first bending member (430), the first branching member (440), the first support member (450), the second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) can form the clamp gripping member (320).

[0070] The above clamp gripping part (320) is also extended away from the above clamp fastening part (310) to effectively grip the talus implant.

[0071] Additionally, the handle portion (100) may include a gripping handle (110) provided to be gripped by a user and a clamp receiving portion (120) extending from the gripping handle (110) and provided to accommodate the first body (410) and the second body (510).

[0072] The gripping handle (110) may include a handle upper portion (113), a handle middle portion (112), and a handle lower portion (111) that extend sequentially from a position close to the gripping receiving portion (120). The handle middle portion (112) may be provided with a thinner thickness than the handle upper portion (113) and the handle lower portion (111). This allows the gripping handle (110) to be gripped more firmly, thereby improving stability.

[0073] Additionally, the fastening cap (200) can accommodate a clamp receiving portion (120) in which the first body (410) and the second body (510) are located, thereby securing the first body (410) and the second body (510) to the clamp receiving portion (120).

[0074] The above fastening cap (200) may include a cap body (210) provided in a hollow shape and a cap receiving hole (220) formed inside the cap body (210). The first body (410) and the second body (510) may be positioned inside the cap receiving hole (220) while being received in the clamp receiving portion (120). That is, the first body (410) and the second body (510) may be arranged to be surrounded by the cap body (210).

[0075] Meanwhile, the clamp receiving portion (120) includes a receiving body (121) that extends from the gripping handle (110) to form a hollow, and a plurality of elastic slits (122) formed in a longitudinal recess at the end of the receiving body (121) to allow the receiving body (121) to move inward. When the fastening cap (200) receives the receiving body (121), the receiving body (121) moves toward the first body (410) and the second body (510) to fix the first body (410) and the second body (510).

[0076] The receiving body (121) may form a hollow on one side that is closed by the gripping handle (110). The receiving body (121) may be provided with an open end extending away from the gripping handle (110). The elastic slit (122) may be formed in a recess along the longitudinal direction on the open side of the receiving body (121). The elastic slit (122) may be provided in multiple numbers.

[0077] For example, if there are two elastic slits (122), the receiving body (121) can be elastically moved two surfaces a predetermined distance. Additionally, if there are three elastic slits (122), the receiving body (121) can be elastically moved three surfaces a predetermined distance.

[0078] The inner diameter of the fastening cap (200) may be smaller than the outer diameter of the receiving body (121). When the fastening cap (200) is coupled to surround the receiving body (121), the diameter of the receiving body (121) may be reduced by the elastic slit (122). Through this, the receiving body (121) has the effect of firmly fixing the first body (410) and the second body (510).

[0079] Additionally, the first body (410) and the second body (510) are combined to form a semi-cylindrical shape that forms a cylinder, and the first body (410) includes a first body recess (411) formed with one end recessed and positioned away from the first avoidance member (420), and a first body projection (412) protruding from one surface of the first body (410) facing the second body (510), and the second body (510) may include a second body step (511) with one end protruding and positioned away from the second avoidance member (520) and fitting with the first body recess (411), and a second body groove (512) recessed and receiving the first body projection (412) on one surface of the second body (510) facing the first body (410). there is.

[0080] The first body (410) and the second body (510) can be firmly fixed without relative movement by means of the combination of the first body recess (411) and the second body step (511) and the combination of the first body projection (412) and the second body groove (512).

[0081] Meanwhile, the first avoidance member (420), the first bending member (430), the first branching member (440), the first support member (450), the second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) may be made of titanium.

[0082] The talus implant may be made of titanium, which has physical properties similar to bone. The first avoidance member (420), the first bending member (430), the first branching member (440), the first support member (450), the second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) may come into direct contact with the talus implant. At this time, the first avoidance member (420), the first bending member (430), the first branching member (440), the first support member (450), the second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) may be made of titanium so that scratches or damage do not occur on the contact surfaces where they come into contact with each other.

[0083] The first avoidance member (420), the first bending member (430), the first branching member (440), the first support member (450), the second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) can be in direct contact with the talus implant. At this time, in order to prevent scratches or damage from occurring at the contact surfaces where they come into contact with each other, the first avoidance member (420), the first bending member (430), the first branching member (440), the first support member (450), the second avoidance member (520), the second bending member (530), the second branching member (540), and the second support member (550) may be manufactured using at least one of titanium, as well as cobalt-chrome alloy, stainless steel, ceramic, ultra-high molecular weight polyethylene (UHMWPE), ceramic-polyethylene composite, and metal-polyethylene composite. It is not limited to the aforementioned materials, and it goes without saying that various materials can be applied as long as they have stiffness and density similar to that of a talus implant.

[0084] This has the effect of improving the stability of the talus implant grip.
