Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an orthopedic navigation probe fixation device. Background Technology

[0002] Surgical navigation systems accurately correlate preoperative or intraoperative imaging data with the patient's anatomical structures on the operating table. During orthopedic surgery, the surgeon holds a probe and points it at the patient's affected limb; the navigation image then displays the surgical site. This navigation image assists orthopedic surgeons in performing surgery more precisely, safely, and quickly. To achieve real-time tracking and positioning, the navigation probe and the affected limb need to be relatively fixed. Existing technologies include surgeries using robotic arms to fix the navigation probe, which can intelligently position and fix the probe to the affected limb. However, this method is costly, increasing the financial burden on patients. Therefore, there is an urgent need for a simple and easily adjustable fixation device for the navigation probe that can meet surgical needs while also saving on surgical costs. Utility Model Content

The lower end of the first support rod is connected to the side of the base. The second support rod has a strip-shaped hole along its length, and a fixing bolt is provided between the upper end of the first support rod and the strip-shaped hole. One end of the second support rod is located above the base, and a clamping buckle for holding the navigation probe is provided on the end of the second support rod.

[0006] As a further improvement to the above technical solution:

[0007] The clamping buckle includes a slot for inserting the navigation probe, and two elastic hooks are provided on opposite sides of the slot opening, which press the navigation probe tightly into the slot.

[0008] A sliding mechanism is provided between the first support rod and the base. The sliding mechanism includes a slider on the first support rod and a groove on the side of the base. The groove is provided along the length of the base, and the slider is slidably disposed in the groove.

[0009] Both the slider and the groove have trapezoidal cross-sections, and the two ends of the groove are sealed.

[0010] The first support rod includes a slidably connected grounded outer tube and an inner tube. The inner tube is located inside the outer tube, and the outer tube is equipped with fastening screws to fix the inner tube. Both the outer tube and the inner tube are made of square tubes.

[0011] The upper end of the seat is provided with a connecting strap for fixing the limbs. The two ends of the connecting strap are fixed to the seat. One end of the connecting strap is provided with a protrusion perpendicular to it. The protrusion passes through the lower end of the seat and fits against the lower end surface of the seat. The other end of the connecting strap is provided with Velcro. The upper end of the seat is provided with a connecting hole. The end of the connecting strap passes through the connecting hole and is fixed by Velcro.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses an orthopedic navigation probe fixation device, which includes a relatively simple base, a first support rod, and a second support rod.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] like Figures 1-3As shown, the orthopedic navigation probe fixation device of this embodiment includes a base 1, a first support rod 2, and a second support rod 3. The base 1 is used to place the patient's limb, and the lower end of the first support rod 2 is connected to the side of the base 1. The second support rod 3 has a strip-shaped hole 4 along its length, and a fixing bolt 5 is provided between the upper end of the first support rod 2 and the strip-shaped hole 4. One end of the second support rod 3 is located above the base 1, and a clamping buckle 6 for clamping the navigation probe 11 is provided on the end of the second support rod 3. Specifically, the clamping buckle 6 includes a slot 61 for inserting the navigation probe 11, and two opposing elastic hooks 62 are provided on both sides of the opening of the slot 61. The two elastic hooks 62 press the navigation probe 11 into the slot 61, thus stably fixing the navigation probe 11 to the end of the first support rod 2.

[0020] To facilitate the fixation of the affected limb to the seat 1, a connecting strap 8 for limb fixation is provided at the upper end of the seat 1, and both ends of the connecting strap 8 are fixed to the seat 1. Specifically, the connecting strap 8 is connected to the seat 1 in the following way: one end of the connecting strap 8 is provided with a protrusion 81 perpendicular to it, which passes through the lower end of the seat 1 and fits against the lower end surface of the seat 1. In this way, the size of the protrusion 81 is larger than the hole on the seat 1 through which the connecting strap 8 passes, so that the protrusion 81 cannot detach from the seat 1. The other end of the connecting strap 8 is provided with Velcro, and the upper end of the seat 1 is provided with a connecting hole 9. The end of the connecting strap 8 passes through the connecting hole 9 and is fixed by Velcro. The affected limb can be fixed to the upper end of the seat 1 using the connecting strap 8.

[0021] In one embodiment, a sliding mechanism 7 is also provided between the first support rod 2 and the base 1. The sliding mechanism 7 includes a slider 71 on the first support rod 2 and a groove 72 on the side of the base 1. The groove 72 is provided along the length direction of the base 1. The slider 71 is slidably disposed in the groove 72. By sliding the slider 71, the position of the first support rod 2 in the length direction of the base 1 can be adjusted. In order to fix the position of the first support rod 2, there is friction between the slider 71 and the groove 72 to avoid accidental contact that could cause its position to move.

[0022] In addition, to prevent the slider 71 from disengaging from the groove 72, both the slider 71 and the groove 72 have trapezoidal cross sections, and the two ends of the groove 72 are sealed.

[0023] To achieve height adjustment, the first support rod 2 includes a slidably connected grounded outer tube 21 and an inner tube 22. The inner tube 22 is located inside the outer tube 21, and the outer tube 21 is provided with a fastening screw 10 to fix the inner tube 22. Specifically, a through screw hole can be opened on the side wall of the outer tube 21, and the fastening screw 10 is connected to the screw hole. By rotating and adjusting the fastening screw 10, the position of the inner tube 22 can be pressed and fixed. The outer tube 21 and the inner tube 22 can both be made of square tubes to avoid using round tubes, thereby preventing the inner tube 22 from rotating, which is beneficial for fixing the navigation probe 11.

[0024] In use, first place the affected limb on the seat 1 and fix it with the connecting strap 8. Then fix the navigation probe 11 in the clamping buckle 6. Move the slider 71 to make the position of the first support rod 2 close to the cross section of the affected area. Then loosen the fastening screw 10 to adjust the height of the first support rod 2 and then lock it to ensure that the navigation probe 11 is above the affected limb. Finally, adjust the bolt 5, move and rotate the second support rod 3 to adjust the direction of the needle tip of the navigation probe 11. With simple adjustments, the navigation probe 11 and the affected limb can be kept relatively fixed, which facilitates the operation based on the navigation image.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
