Abstract
Description
Technical Field
[0001] This utility model relates to a surgical support, and more particularly to an adjustable leg surgical support for use with a surgical robot. Background Technology
[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.
[0003] With the development of digital imaging technology, the use of navigation robots for assisted surgical procedures has become increasingly common. Patients should maintain a stable position during surgery so that the navigation robot can acquire stable images before and during the procedure for planning and implementing the surgical path. During surgery, surgeons typically immobilize patients on the operating table with medical bandages. However, due to the complexity and diversity of trauma and fractures, flexion and extension are often necessary to achieve a good surgical position. Maintaining stability during adjustment and final fixation is difficult due to the lack of a stable support. In the past, when using navigation robots for assisted surgical procedures, the patient positioning device was usually fixed to bony structures near the surgical site using guide pins, causing unnecessary injury to the patient.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0058] This device is as follows Figure 1 As shown: It includes a bottom connection mechanism 1 connected to the operating table, an adjustment mechanism 2 for fixing the legs on the bottom connection mechanism 1, and a tracer mechanism 3 for installing a tracking device.
[0059] like Figure 2 As shown, the bottom connecting mechanism 1 includes a locking component 11, a left base plate 12, a right base plate 13, and a connecting rod 14. The left base plate 12 and the right base plate 13 are connected to the operating table via the locking component 11. One end of the connecting rod 14 is fixedly connected to the right base plate 13, and the other end is slidably connected to the left base plate 12.
[0060] like Figure 3 As shown, the connecting rod 14 has a thread at one end and a smooth rod at the other end. The threaded end is connected to the internal thread of the right base plate 13. The smooth rod part can be adjusted through the corresponding through hole of the left base plate 12 to adjust the distance between the left base plate 12 and the right base plate 13 of this device to adapt to the fixed position of the operating table.
[0061] There are two or more connecting rods 14.
[0062] The locking component 11 is a U-shaped clamp that is locked by a screw.
[0063] like Figure 4 As shown, the adjustment mechanism 2 includes a bottom sliding component 21, a left adjustment bracket 22, a right adjustment bracket 23, and a leg fixing component 24. The left adjustment bracket 22 and the right adjustment bracket 23 have the same structure, are rotatably connected at the top, and are slidably connected to the connecting rod 14 at the bottom through a bottom sliding component 21.
[0064] like Figure 5 As shown, the bottom sliding component 21 includes a bottom sliding seat 211, a locking knob 212, and a first bolt 213. The bottom sliding seat 211 passes through the connecting rod 14 and is locked by the knob 212 and the connecting rod 14. The bottom sliding seat 211 is movably connected to the left adjusting bracket 22 and the right adjusting bracket 23 by the first bolt 213.
[0065] like Figure 6 As shown, the left adjusting bracket 22 includes a sliding support plate 221, a toothed support plate 222, an adjusting slider 223, a locking bolt 224, and a toothed limit block 225.
[0066] like Figure 7As shown, the toothed limiting block 225 is installed in the groove 226 of the sliding support plate 221. The groove of the sliding support plate 221 is perpendicular to the sliding direction of the sliding support plate 221, and the toothed limiting block 225 can slide left and right in the groove of the sliding support plate 221. A second rack portion 229 and a second smooth portion 230 are fixed on one side of the toothed limiting block 225 near the toothed support plate 222, and an adjusting slider 223 is fixed on the other side. The adjusting slider 223 is fixed to the sliding support plate 221 by a locking bolt 224.
[0067] The toothed support plate 222 has a first rack portion 227 and a first smooth portion 228 fixedly mounted on the side near the sliding support plate 221. When the toothed limiting block 225 slides to the position of the second rack portion of the toothed support plate 222, as... Figure 8 As shown, the bottom rack of the toothed limiting block 225 meshes with the rack of the toothed support plate 222, thus fixing the positions of the sliding support plate 221 and the toothed support plate 222; when the toothed limiting block 225 slides to the position of the second smooth part of the toothed support plate 222, as...

[0071] like Figure 12 As shown, bolt 245 is threadedly connected to support 241. Figure 13The right guard plate 243 and the left guard plate 244 are slidably connected to the support base 241 via a T-slot and locked by guard plate bolts 245. The distance between the right guard plate 243 and the left guard plate 244 can be adjusted left and right. The right guard plate 243 includes a first protrusion 2431 and a second protrusion 2432. The first protrusion 2431 is hollow in the middle. The left guard plate 244 is provided with a first U-shaped frame 2441 and a second U-shaped frame 2442. The first protrusion 2431 can be inserted into the first U-shaped frame 2441, and the second protrusion 2432 can be inserted into the second U-shaped frame 2442. The guard plate bolts 245 pass through the middle of the first protrusion 2431. After tightening, the first protrusion 2431 and the first U-shaped frame 2441 are locked, thereby fixing the distance between the right guard plate 243 and the left guard plate 244.
[0072] like Figure 14 As shown, the tracer component 3 includes a locking seat 31, an intermediate connecting component 32, and a top positioning component 33.
[0073] Locking seat 31, such as Figure 15 As shown, the system includes a base 311, a base locking handle 312, a universal joint 313, and a top locking handle 314. The base 311 can be locked and fixed to the connecting rod 14 or the left adjusting bracket 22 and right adjusting bracket 23 via the base locking handle 312. The base 311 and the universal joint 313 can rotate 360° and lock together via an annular toothed plate and the locking handle 314, facilitating the adjustment of the tracer's position and enabling the optical tracking system to receive its signals.
[0074] like Figure 16 As shown, the intermediate connecting component 32 includes a connecting rod 321 and a locking assembly 322. The lower end of the connecting rod 321 is connected to a through hole on the universal seat 313 and is locked by the top locking handle 314.
[0075] like Figure 17 As shown, the top positioning component 33 includes a fixing rod 331 and a positioning bracket 332. The two are fixed together by bolts. The bottom of the fixing rod 331 is connected to a locking assembly 322. The locking assembly 322 includes a clamp and a fastening bolt for fixing the top positioning component 33 to the appropriate position on the connecting rod 321.
[0076] When using this device, the bottom connecting mechanism 1 is installed on the operating table, and the distance between the right guard plate 243 and the left guard plate 244 is adjusted according to the thickness of the legs. The lengths of the left adjusting bracket 22 and the right adjusting bracket 23 are adjusted according to the length of the legs.
[0077] Adjust the angles of the left adjustment bracket 22 and the right adjustment bracket 23 according to the surgical site. After the angles are adjusted, lock the bottom sliding seat 211 by locking the locking knob 212.
[0078] Finally, adjust the tracer component 3 according to the surgical site to facilitate the optical tracking system receiving its signal.
