[0050] This application provides a nail holder and a nail holding system. These will be described in detail below.

[0051] First, this application provides a nail holder.

[0052] Figure 1 This is a schematic diagram of one embodiment of the nail holder provided in this application. Figure 2 An exploded view of one embodiment of the nail holder provided in this application. Figure 3 for Figure 1 A cross-sectional view along the AA direction. (See example...) Figures 1 to 3 As shown, the nail holder 10 includes a handle 11 and a retaining member 12. One end of the handle 11 has a nail-holding hole 113 for inserting a nail 20. The retaining member 12 is movably connected to the handle 11, and the retaining member 12 can be in a retaining position relative to the handle 11 (e.g., ...). Figure 3 The retaining member 12 moves between the holding position and the separating position. When the retaining member 12 is in the holding position, it is used to hold the nail 20 inserted into the nail holder hole 113 so that the nail holder 10 can hold the nail 20 stably. When the retaining member 12 is in the separating position, it is used to separate from the nail 20 inserted into the nail holder hole 113 so that the nail 20 can be separated from the nail holder 10.

[0053] It should be noted that the retaining member 12 can be rotatably connected to the handle 11, allowing the retaining member 12 to rotate relative to the handle 11 between a retaining position and a disengaged position. Alternatively, the retaining member 12 can be slidably connected to the handle 11, allowing the retaining member 12 to slide relative to the handle 11 between a retaining position and a disengaged position. It is sufficient that the retaining member 12, when in the retaining position, can retain the nail 20 inserted into the nail holder hole 113, and that the retaining member 12, when in the disengaged position, can disengage from the nail 20 inserted into the nail holder hole 113.

[0054] Among them, such as Figure 4 As shown, nail 20 can be a screw. A screw is a nail 20 with threads on its outer circumferential surface. Or, as... Figure 5 As shown, nail 20 can be a smooth nail. A smooth nail is a nail 20 whose outer peripheral surface is not threaded. The outer peripheral surface of a smooth nail can be a smooth surface, or it can be a nail 20 with grooves or protrusions on its outer peripheral surface.

[0055] In some embodiments, the nail holder 10 further includes an elastic element 13 connected to the handle 11. The elastic element 13 is connected to the retaining member 12 to drive the retaining member 12 from the disengaged position to the retaining position. Thus, when the nail 20 is inserted into the nail holding hole 113 of the handle 11, the retaining member 12 can be held in the retaining position by the action of the elastic element 13, thereby improving the nail holding stability of the nail holder 10.

[0056] In some embodiments, such as Figures 1 to 3 As shown, the retaining member 12 may also include a pressing part 121 for receiving external pressing force to move the retaining member 12 from the retaining position to the disengaging position.

[0057] The nail holder 10 provided in this embodiment has a nail holding hole 113 for inserting nails 20 at one end of the handle 11. A retaining member 12 is movably connected to the handle 11, allowing the retaining member 12 to move between a retaining position and a disengaged position relative to the handle 11. An elastic member 13 drives the retaining member 12 from the disengaged position to the retaining position. When the nail 20 is inserted into the nail holding hole 113 of the handle 11, the retaining member 12 is stably held in the retaining position under the action of the elastic member 13, ensuring stable retention of the nail 20 inserted into the nail holding hole 113. When it is necessary to separate the nail holder 10 from the nail 20, simply press the pressing part 121 of the retaining member 12. Under the pressure of the pressing part 121, the retaining member 12 moves from the retaining position to the disengaged position, releasing the nail 20 and facilitating separation of the nail holder 10 from the nail 20. This operation is very convenient and helps improve the efficiency of orthopedic surgery.

[0058] It should be noted that the external pressing force received by the pressing part 121 can be the force applied by a human hand to the pressing part, for example, a human hand pressing the pressing part 121 to apply pressing force. Alternatively, the external pressing force received by the pressing part 121 can also be the force applied by a surgical robot or other medical device to the pressing part, for example, the operating parts of the surgical robot or other medical device are connected to the pressing part and press the pressing part 121 to apply pressing force.

[0059] like Figures 1 to 3 As shown, the handle 11 includes a connecting portion 114, and a retaining member 12 is rotatably connected to the connecting portion 114, so that the retaining member 12 is rotatably connected to the handle 11, and the retaining member 12 can rotate relative to the handle 11 between a retaining position and a disengaged position. The retaining member 12 includes a retaining portion 124 for retaining the nail 20 inserted into the nail holder hole 113. When the retaining member 12 is in the retaining position, the retaining portion 124 of the retaining member 12 can retain the nail 20 inserted into the nail holder hole 113; when the retaining member 12 is in the disengaged position, the retaining portion 124 of the retaining member 12 can disengage from the nail 20 inserted into the nail holder hole 113.

[0060] In some embodiments, the connecting portion 114 may be located between the pressing portion 121 and the holding portion 124, so that after the doctor applies pressure to the pressing portion 121, the holding member 12 rotates relative to the handle 11 from the holding position to the disengaged position.

[0061] The retaining member 12 is rotatable relative to the connecting part 114 about the rotation axis X. The rotation axis X can be positioned between the pressing part 121 and the retaining part 124, so that after the doctor applies pressure to the pressing part 121, the retaining member 12 can rotate relative to the handle 11 from the retaining position to the disengaged position. The rotation axis X is substantially perpendicular to the length direction of the handle 11.

[0062] In some embodiments, the elastic member 13 may include a first elastic member located on the side of the retaining member 12 facing the handle 11. The rotation axis X of the retaining member 12 relative to the connecting portion 114 is located between the first elastic member and the retaining portion 124. One end of the first elastic member abuts against the handle 11, and the other end of the first elastic member abuts against the retaining member 12. The first elastic member is used to push the retaining member 12 from the disengaged position to the retained position. This makes the installation of the first elastic member more stable, so that the second elastic member can stably push the retaining member 12 from the disengaged position to the retained position.

[0063] The first elastic element can be any elastic component, such as a linear spring or rubber, that can provide a thrust to the retaining element 12, causing the retaining element 12 to rotate from the disengaged position to the retaining position.

[0064] In other embodiments, the elastic member 13 may include a second elastic member located on the side of the retaining member 12 facing the handle 11. The second elastic member is located between the rotation axis X and the retaining portion 124. One end of the second elastic member is connected to the handle 11, and the other end is connected to the retaining member 12. The second elastic member is used to pull the retaining member 12 from the separated position to the retained position. This makes the installation of the second elastic member more stable, so that the second elastic member can stably pull the retaining member 12 from the separated position to the retained position.

[0065] The second elastic element can be any elastic component, such as a tension spring or rubber, that can provide tension to the retaining element 12, causing the retaining element 12 to rotate from the disengaged position to the retaining position.

[0066] It should be noted that the elastic element 13 may include only one of the first elastic element and the second elastic element, or it may include both the first elastic element and the second elastic element. Of course, the latter allows the elastic element 13 to apply a greater elastic force to the retaining element 12, making the retaining element 12 more stably held in the retaining position.

[0067] In some embodiments, the elastic member 13 can be positioned on the side of the retaining member 12 facing the handle 11. Thus, the elastic member 13 can be limited by the retaining member 12 and the handle 11, thereby making the installation of the elastic member 13 more stable. Furthermore, the elastic member 13 can stably apply a pushing or pulling force to the retaining member 12 to push or pull the retaining member 12 from the disengaged position to the retaining position.

[0068] A first mounting hole 115 is provided on the side of the handle 11 facing the retaining member 12, and one end of the elastic member 13 is located in the first mounting hole 115. Thus, the first mounting hole 115 can limit one end of the elastic member 13, making the connection between the elastic member 13 and the handle 11 more stable.

[0069] Additionally, a second mounting hole 122 can be provided on the side of the retaining member 12 facing the handle 11, and the other end of the elastic member 13 is located in the second mounting hole 122. Thus, the second mounting hole 122 can limit the other end of the elastic member 13, making the connection between the elastic member 13 and the retaining member 12 more stable.

[0070] It should be noted that the first mounting hole 115 can be provided on the handle 11 and the second mounting hole 122 can be provided on the retaining member 12 at the same time, or the first mounting hole 115 can be provided only on the handle 11, or the second mounting hole 122 can be provided only on the retaining member 12. Of course, the former can make the installation of the elastic member 13 more stable.

[0071] Specifically, the pressing part 121 has a second mounting hole 122 on the side facing the handle 11, and the handle 11 has a first mounting hole 115 corresponding to the position of the second mounting hole 122. One end of the elastic member 13 is located in the first mounting hole 115 and abuts against the bottom surface of the first mounting hole 115. The other end of the elastic member 13 is located in the second mounting hole 122 and abuts against the bottom surface of the second mounting hole 122.

[0072] In some embodiments, such as Figures 1 to 3 As shown, the connecting portion 114 can be protruding from the handle 11 on the side facing the retaining member 12. This makes the connection between the retaining member 12 and the connecting portion 114 more convenient. Specifically, the connecting portion 114 can include at least one protrusion 1141, and the retaining member 12 can include at least one rotating portion 123, which is connected to the protrusion 1141, allowing the retaining member 12 and the connecting portion 114 to be rotatably connected.

[0073] In some embodiments, the connecting portion 114 may include two protrusions 1141, which are located on both sides of a rotating portion 123 along the circumference of the handle 11, and the two protrusions 1141 are rotatably connected to the rotating portion 123 respectively. This makes the rotatable connection between the retaining member 12 and the connecting portion 114 more stable.

[0074] Specifically, the nail holder 10 also includes a pin 14 that passes through two protrusions 1141 and a rotating part 123 located between the two protrusions 1141, so as to rotatably connect the two protrusions 1141 of the connecting part 114 and the rotating part 123 of the retaining member 12.

[0075] In other embodiments, the retaining member 12 may include two rotating parts 123, which are located on both sides of a protrusion 1141 along the circumference of the handle 11. The two rotating parts 123 are rotatably connected to the protrusion 1141 respectively, so that the rotatable connection between the retaining member 12 and the connecting part 114 is more stable.

[0076] The pin 14 can pass through the two rotating parts 123 and the middle protrusion 1141 to rotatably connect the protrusion 1141 of the connecting part 114 and the two rotating parts 123 of the retaining member 12.

[0077] like Figures 1 to 3 As shown, the handle 11 includes a first end 111 and a second end 112, with the first end 111 having a nail-holding hole 113. Specifically, the end face of the first end 111 of the handle 11 has a nail-holding hole 113. The nail-holding hole 113 extends along the length direction of the handle 11.

[0078] The connecting part 114 can be spaced apart from the first end 111 of the handle 11. This reduces the risk of injury to the patient caused by the connecting part 114 coming into contact with the patient when the doctor inserts the nail 20 into the patient's body using the nail holder 10.

[0079] like Figures 1 to 3 As shown, the handle 11 includes a connecting section 118 and a handhold section 119. The connecting section 118 extends from a first end 111 of the handle 11 to a second end 112 and then to the handhold section 119. The handhold section 119 is for a doctor to hold. The second end 112 of the handle 11 is located at the end of the handhold section 119 away from the connecting section 118.

[0080] In some embodiments, the connecting part 114 can be provided on the connecting section 118 so that after the retaining member 12 is connected to the connecting part 114, the retaining member 12 is closer to the nail holding hole 113 of the first end 111 of the handle 11 so that the retaining member 12 can hold the nail 20 inserted into the nail holding hole 113.

[0081] The distance from the connecting part 114 to the first end 111 can be greater than the distance from the connecting part 114 to the hand grip section 119, thereby creating a larger gap between the connecting part 114 and the first end 111 of the handle 11, further reducing the risk of the connecting part 114 coming into contact with the patient and causing injury to the patient.

[0082] In some embodiments, such as Figure 2 and Figure 3 As shown, an abutment portion 116 may be provided on the handle 11 or the connecting portion 114. The abutment portion 116 is used to abut against the retaining member 12 to limit the angle of rotation of the retaining member 12 from the disengaged position to the retaining position. This prevents the retaining member 12 from rotating too much from the disengaged position to the retaining position under the drive of the elastic member 13, thus affecting the connection stability between the elastic member 13 and the retaining member 12 or the handle 11. In particular, when the elastic member 13 is clamped between the retaining member 12 and the handle 11, the risk of the elastic member 13 detaching from between the retaining member 12 and the handle 11 can be reduced.

[0083] Specifically, the abutment portion 116 is located on the side of the handle 11 facing the retaining member 12. When the retaining member 12 rotates from the disengaged position to the retaining position, the abutment portion 116 abuts against the retaining member 12 to restrict the retaining member 12 from continuing to rotate.

[0084] In some embodiments, a clearance hole 117 may be provided on the side of the handle 11 facing the retaining member 12. The clearance hole 117 communicates with the nail holding hole 113. The clearance hole 117 is used to avoid the retaining member 12, allowing a portion of the retaining member 12 to enter the nail holding hole 113 and engage with the nail 20 inserted into the nail holding hole 113. Thus, when the retaining member 12 rotates from the disengaged position to the engaged position, a portion of the retaining member 12 can pass through the clearance hole 117 and enter the nail holding hole 113, stably engaging with the nail 20 inserted into the nail holding hole 113.

[0085] The retaining member 12 has a retaining portion 124 protruding from the side facing the handle 11. The retaining portion 124 is located at the end of the retaining member 12 near the first end 111. A clearance hole 117 is provided near the first end 111 of the handle 11. The clearance hole 117 is used to avoid the retaining portion 124 of the retaining member 12. When the retaining member 12 is rotated from the disengaged position to the retaining position, the retaining portion 124 of the retaining member 12 can pass through the clearance hole 117 and enter the nail holding hole 113, and stably retain the nail 20 inserted into the nail holding hole 113.

[0086] In other embodiments, when the retaining member 12 is in the retaining position, a portion of the retaining member 12 may be located on the side of the first end 111 of the handle 11 away from the second end 112, so that the retaining member 12 can be engaged with the nail 20 inserted into the nail holding hole 113.

[0087] In some embodiments, the nail holding hole 113 of the handle 11 may be made available for insertion of at least two different types and / or different models of nails 20, so that the nail holder 10 can hold the nails 20 for at least two different types and / or different models of nails 20.

[0088] Among them, such as Figure 3 As shown, the nail holding hole 113 may include a first hole segment 1131 and a second hole segment 1132, the radial cross-sections of the first hole segment 1131 and the second hole segment 1132 having different shapes and / or sizes, the first hole segment 1131 and the second hole segment 1132 being used for inserting nails 20 of different models and / or different types, thereby enabling the nail holding hole 113 to be used for inserting at least two different models and / or different types of nails 20.

[0089] In some embodiments, the radial cross-sectional shape of the first hole segment 1131 can be polygonal. Thus, the nail 20 with the radial cross-sectional shape of the head 21 corresponding to the polygon can be inserted into the first hole segment 1131 and stably held in the first hole segment 1131 by the holding member 12.

[0090] The radial cross-sectional shape of the first hole segment 1131 can be triangular, quadrilateral, pentagonal, hexagonal, etc., depending on the type of nail 20 required. For example... Figure 4As shown, the radial cross-sectional shape of the first hole segment 1131 is hexagonal, and the nail 20 is a screw with a head 21 having a radial cross-sectional shape of hexagonal. The shape of the first hole segment 1131 is adapted to the shape of the head 21 of the nail 20.

[0091] In some embodiments, the radial cross-section of the second hole segment 1132 can be circular. Thus, a nail 20 with a correspondingly circular radial cross-sectional shape for its head 21 can be inserted into the second hole segment 1132 and stably held within it by the retaining member 12. For example... Figure 5 As shown, the radial cross-sectional shape of the second hole segment 1132 is circular, and the nail 20 is a smooth nail with a radial cross-section of a head 21 that is circular. The shape of the second hole segment 1132 is adapted to the shape of the head 21 of the nail 20.

[0092] In some embodiments, the inscribed circle diameter of the first hole segment 1131 may be larger than the inscribed circle diameter of the second hole segment 1132, so that the first hole segment 1131 and the second hole segment 1132 have different shapes and sizes, so that the first hole segment 1131 and the second hole segment 1132 can be used for inserting nails of different models and / or different types, respectively.

[0093] In some embodiments, the first hole segment 1131 and the second hole segment 1132 can be sequentially distributed in a direction away from the first end 111. Thus, the first hole segment 1131 can be used to insert nails 20 with shorter head 21 lengths, and the second hole segment 1132 can be used to insert nails 20 with longer head 21 lengths, which is beneficial for the nail holder 10 to hold two types of nails 20 with large differences in shape.

[0094] In some embodiments, a first slot 211 may be provided on the outer peripheral surface of the nail 20. When the retaining member 12 is in the retaining position, it is used to insert into the first slot 211 so that the retaining member 12 and the nail 20 inserted into the nail holding hole 113 are more stably retained.

[0095] Specifically, such as Figure 4 As shown, a first slot 211 is formed on the outer peripheral surface of the head 21 of the nail 20. When the head 21 of the nail 20 is inserted into the nail holding hole 113, the first slot 211 located on the head 21 of the nail 20 corresponds to the position of the clearance hole 117. When the retaining member 12 moves from the separated position to the retaining position, a part of the retaining member 12 passes through the clearance hole 117 and inserts into the first slot 211 to retain the nail 20.

[0096] In other embodiments, the retaining member 12 may have a second slot. When the retaining member 12 is in the retaining position, a portion of the nail 20 is inserted into the second slot so that the retaining member 12 is stably retained with the nail 20 inserted into the nail holding hole 113.

[0097] Specifically, a second slot can be formed in the holding portion 124 of the holding member 12, and a holding protrusion can be provided on the outer peripheral surface of the head 21 of the nail 20. When the holding member 12 moves from the separated position to the holding position, the holding portion 124 of the holding member 12 passes through the clearance hole 117 and enters the nail holding hole 113. The second slot is located on the side of the holding portion 124 facing the nail holding hole 113. The holding protrusion located on the head 21 of the nail 20 is inserted into the second slot so that the holding member 12 holds the nail 20.

[0098] In other embodiments, when the retaining member 12 is in the retaining position, the retaining member 12 can also directly abut against the outer peripheral surface of the nail 20 inserted into the nail holding hole 113 to retain the nail 20 inserted into the nail holding hole 113.

[0099] like Figure 5 As shown, the clearance hole 117 is located in the first hole section 1131 of the nail holding hole 113. When the optical nail is inserted into the nail holding hole 113 and the retaining member 12 is in the retaining position, the head 21 of the optical nail is inserted into the second hole section 1132 of the nail holding hole 113. The retaining member 12 passes through the clearance hole 117 and abuts against the outer peripheral surface of the portion of the optical nail located in the first hole section 1131 to retain the optical nail.

[0100] In some embodiments, such as Figures 3 to 5 As shown, the handle 11 is also provided with a cleaning hole 110, which is connected to the nail holding hole 113. The cleaning hole 110 extends from the inner peripheral surface of the nail holding hole 113 to the outer peripheral surface of the handle 11, so as to facilitate cleaning of the nail holding hole 113 through the cleaning hole 110.

[0101] This application embodiment also provides a nail holder. The nail holder 10 includes:

[0102] The handle 11 has a nail holding hole 113 at one end for inserting nails 20. The nail holding hole 113 includes a first hole segment 1131 and a second hole segment 1132. The radial cross-sections of the first hole segment 1131 and the second hole segment 1132 have different shapes and / or sizes. The first hole segment 1131 and the second hole segment 1132 are respectively used for inserting nails 20 of different models and / or different types.

[0103] The retaining member 12 is movably connected to the handle 11. The retaining member 12 can move between a retaining position and a disengaged position relative to the handle 11. When the retaining member 12 is in the retaining position, it is used to retain the nail 20 inserted into the nail holding hole 113. When the retaining member 12 is in the disengaged position, it is used to disengage from the nail 20 inserted into the nail holding hole 113.

[0104] In some embodiments, the radial cross-section of the first hole segment 1131 is polygonal, and the radial cross-section of the second hole segment 1132 is circular; or, the diameter of the inscribed circle of the first hole segment 1131 is larger than the diameter of the inscribed circle of the second hole segment 1132.
