In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0039] The following combination Figures 1 to 9 The utility model describes a cervical vertebra self-stabilizing fusion device holder.

[0040] See also Figures 1 to 6 As shown, the cervical vertebra self-stabilizing fusion device holder provided by the embodiment of the present invention includes: a holder 10 and a drive assembly 20.

[0041] A holding portion 111 is provided at one end of the holding member 10 , a plurality of clamping jaws 1111 are provided at the end of the holding portion 111 , a contraction gap 1112 is provided between the plurality of clamping jaws 1111 , and a contact portion 1113 with a certain slope is provided on the outer wall of the holding portion 111 .

[0042] The driving assembly 20 includes a driving member 210 and a rotating sleeve 220 . The driving member 210 and the rotating sleeve 220 are both sleeved on the holding member 10 , and the driving member 210 is connected to the rotating sleeve 220 .

[0043] The rotating sleeve 220 is threadedly engaged with the holding member 10 to drive the holding member 10 to move axially when the rotating sleeve 220 is rotated, so that the end of the driving member 210 contacts or discontinuities with the contact portion 1113 , compressing or releasing the shrinkage gap 1112 .

[0044] The present invention provides a holder for a cervical vertebrae self-stabilizing fusion device that can stably hold the device during implantation, simplifying the clamping and release procedures. Furthermore, the holder's rod-like structure significantly reduces its radial footprint and enhances the surgical field of view.

[0045] Specifically, by configuring the rotating sleeve 220 and the holding member 10 to be threaded, when holding, the rotating sleeve 220 is rotated in the first direction, and the holding member 10 can move along its axial direction close to the driving member 210. When it moves to a certain position, the end of the driving member 210 close to the holding portion 111 can contact the contact portion 1113 of the outer wall of the holding portion 111 with a certain slope, and press the contraction gap 1112, so that the claws clamp the cervical vertebra self-stabilizing fusion device. After the cervical vertebra self-stabilizing fusion device is implanted, the rotating sleeve 220 is rotated in the second direction (opposite to the first direction), and the holding member 10 can move along its axial direction away from the driving member 210, and the end of the driving member 210 close to the holding portion 111 gradually disengages from the contact portion 1113, so that the contraction gap 1112 gradually returns to its initial state, and the clamping jaws 1111 release the cervical vertebra self-stabilizing fusion device to complete the disengagement.

[0046] See also Figure 5 and Figure 6 As shown, two clamping jaws 1111 are provided at opposite ends of the holding portion 111, with a contraction gap 1112 located between the two clamping jaws 1111. When the contraction gap 1112 contracts inward, the distance between the two clamping jaws 1111 decreases, enabling stable clamping of the cervical vertebrae self-stabilizing fusion device. When the contraction gap 1112 returns to its initial state, the distance between the two clamping jaws 1111 increases, allowing the device to be detached from the cervical vertebrae self-stabilizing fusion device.

[0047] It should be noted that the number of clamping jaws 1111 is not limited to two, and can also be set to three or more based on requirements (such as the specific structure of the cervical vertebrae self-stabilizing fusion device). When the number of clamping jaws 1111 is set to three or more, the multiple clamping jaws 1111 are evenly distributed along the circumference.

[0048] See also Figures 3 to 5As shown, the holding piece 10 includes a holding piece body 110 and a connecting sleeve 120, the holding portion 111 is arranged at the end of the holding piece body 110, the connecting sleeve 120 is sleeved on the holding piece body 110 and has an interference fit with the holding piece body 110, and the inner wall of the rotating sleeve 220 is threadedly engaged with the outer wall of the connecting sleeve 120.

[0049] The inner wall of the rotating sleeve 220 and the outer wall of the connecting sleeve 120 are both provided with trapezoidal threads with a large pitch, which can easily rotate the rotating sleeve 220 and enable the holding member 10 to have a large forward and backward extension when the rotating sleeve 220 rotates a small amount.

[0050] The end of the connecting sleeve 120 is provided with a connector 121, which has a hammering surface 1211. This surface is designed to withstand hammering during implantation, facilitating the implantation process. Connector 121 is also used to connect to external components. If the device does not fit the lesion properly, it can be removed using connector 121 and the external component.

[0051] See also Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the driving member 210 is rotationally connected to the rotating sleeve 220. By configuring the driving member 210 and the rotating sleeve 220 to be rotationally connected, the driving member 210 does not rotate with the rotating sleeve 220 when the rotating sleeve 220 is rotated, thereby reducing the driving force when rotating the rotating sleeve 220, thereby facilitating the rotation of the rotating sleeve 220. Furthermore, since the driving member 210 does not rotate with the rotating sleeve 220, rotational friction between the end of the driving member 210 and the contact surface can be prevented, thereby preventing wear on the end of the driving member 210 and the contact surface.

[0052] Specifically, in this embodiment, one end of the rotating sleeve 220 is sleeved on the driving member 210 , and the two are configured to be rotatably connected.

[0053] See also Figure 3 、 Figure 4 and Figure 8 As shown, according to some embodiments of the present invention, a resilient clip 211 is provided at one end of the driver 210. The resilient clip 211 comprises a plurality of resilient snap plates 2111 evenly distributed along the circumference. A retaining protrusion is provided at the end of the resilient snap plate 2111, each of which has a mounting guide surface. The inner wall of the rotating sleeve 220 is provided with an axial retaining groove that matches the retaining protrusion. This simplifies assembly of the device and, after assembly, provides axial retention of the driver 210 without affecting the rotational connection between the driver 210 and the rotating sleeve 220.

[0054] Specifically, during assembly, one end of the elastic clip 211 of the driving member 210 is aligned with the corresponding open end of the rotating sleeve 220, and an axial force is applied to the driving member 210. Under the guidance of the installation guide surface formed by the limiting protrusion, the multiple elastic clip plates 2111 shrink radially and continue to push the driving member 210 into the rotating sleeve 220. When the limiting protrusion falls into the axial limiting groove set on the inner wall of the rotating sleeve 220, the multiple elastic clip plates 2111 return to their initial state.

[0055] See also Figure 3 As shown, according to some embodiments of the present invention, a circumferential limiting groove 112 is provided in the axial direction on the outer wall of the holding member 10, and a limiting pin 212 is provided on the driving member 210. The end of the limiting pin 212 slides in engagement with the circumferential limiting groove 112. This allows the driving member 210 to maintain its current position when the rotating sleeve 220 is rotated, preventing it from rotating circumferentially, ensuring its stability during use, and preventing the end of the driving member 210 from generating rotational friction with the contact surface, thereby preventing wear on the end of the driving member 210 and the contact surface.

[0056] Specifically, due to the rotational connection between driver 210 and rotating sleeve 220, a certain amount of friction exists between them. When this friction is excessive, rotating sleeve 220 will cause driver 210 to rotate circumferentially, affecting the stability of the device during use. Furthermore, when the end of driver 210 is in contact with the contact surface, rotation of driver 210 will increase the friction between them and accelerate component wear.

[0057] See also Figure 9 As shown, according to some embodiments of the present invention, a mating portion 213 that matches the contact portion 1113 is provided at the end of the driving member 210 near the holding portion 111. By providing the mating portion 213 that matches the contact portion 1113 at the end of the driving member 210 near the holding portion 111, the contact area between the end of the driving member 210 near the holding portion 111 and the contact portion 1113 can be increased, thereby improving the stability of the clamping jaws 1111 when clamping.

[0058] Specifically, the matching portion 213 is a concave inclined surface at one end of the driving member 210 close to the holding portion 111 , and has a larger contact area with the contact portion 1113 , thereby improving the stability of the clamping jaws 1111 when clamping.

[0059] See also Figure 5 and Figure 6As shown, according to some embodiments of the present invention, a stress relief groove 1114 is provided at the end of the contraction seam 1112. The stress relief groove 1114 is used to relieve stress at the end of the contraction seam 1112. By providing the stress relief groove 1114 at the end of the contraction seam 1112, stress concentration at the end of the contraction seam 1112 can be effectively reduced, preventing material fatigue, cracking, or failure, and extending the service life of the holding member 10.

[0060] Specifically, the stress release groove 1114 is a circular groove that passes through the holding piece 10 , and one end of the stress release groove 1114 is connected to the end of the contraction seam 1112 .

[0061] See also Figures 7 to 9 As shown, according to some embodiments of the present invention, the driving member 210 is provided with a first cleaning tank 214, which is in communication with the interior space of the driving member 210; the rotating sleeve 220 is provided with a second cleaning tank 221, which is in communication with the interior space of the rotating sleeve 220. By providing the first cleaning tank 214 and the second cleaning tank 221 on the driving member 210 and the rotating sleeve 220, respectively, cleaning the interiors of the driving member 210 and the rotating sleeve 220 is facilitated.

[0062] See also Figure 7 As shown, according to some embodiments of the present invention, a grip portion 222 is formed on the outer wall of the rotating sleeve 220. By providing the grip portion 222 on the outer wall of the rotating sleeve 220, the rotating sleeve 220 can be easily rotated by the grip portion 222.

[0063] Specifically, the gripping portion 222 is friction teeth uniformly distributed along the circumferential direction on the outer wall of the rotating sleeve 220 .

[0064] It can be seen from the description of the above embodiments that the cervical vertebrae self-stabilizing fusion device holder provided by the present invention has at least the following advantages.

[0065] (1) The present invention provides a holder for a cervical vertebrae self-stabilizing fusion device, which can stably clamp the cervical vertebrae self-stabilizing fusion device when it is implanted, simplifying the clamping and release operations of the cervical vertebrae self-stabilizing fusion device. The holder is an overall rod-shaped structure, which significantly reduces the radial space occupied by the holder and improves the surgical field of view.

[0066] (2) The cervical vertebra self-stabilizing fusion device holder provided by the present invention is configured to be rotationally connected to the driving member 210 and the rotating sleeve 220. When the rotating sleeve 220 is rotated, the driving member 210 does not rotate with the rotating sleeve 220, thereby reducing the driving force when rotating the rotating sleeve 220. In addition, since the driving member 210 does not rotate with the rotating sleeve 220, it is possible to prevent the end of the driving member 210 from generating rotational friction with the contact surface, thereby preventing wear on the end of the driving member 210 and the contact surface.

[0067] (3) The cervical vertebra self-stabilizing fusion device holder provided by the present invention can keep the driving member 210 in its current position at all times when the rotating sleeve 220 is rotated by arranging a circumferential limit groove 112 along the axial direction on the outer wall of the holder 10 and arranging a limit pin 212 on the driving member 210, thereby preventing the driving member 210 from rotating in the circumferential direction, ensuring its stability during use, and preventing the end of the driving member 210 from generating rotational friction with the contact surface, thereby preventing the end of the driving member 210 and the contact surface from being worn.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
