Detailed Description

The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.

The automatic scissors-type bone groove decompression machine head device for the spinal surgery, as shown in figures 1 to 3, comprises a machine head connecting seat 1, and is characterized in that a step-shaped cavity 2 is arranged in the machine head connecting seat 1, and a telescopic guide device is arranged in the step-shaped cavity 2. Specifically, in order to realize effective longitudinal guidance, ensure that the surgical device of follow-up installation possess better straightness that hangs down, improve the operation precision, flexible guiding device includes flexible post 3, is provided with the accommodation space in the step cavity 2 and between the flexible post 3. Meanwhile, in order to realize stable positioning and buffering during up-and-down movement, an upper telescopic spring 4 can be arranged at the upper end of the adjusting space, and a lower telescopic spring 5 can be arranged at the lower end of the adjusting space. Therefore, the two groups of telescopic springs realize effective positioning and buffering. In view of the requirements of the combined use, in order to meet the necessary driving of the osteotomy, the upper end of the telescopic column 3 is connected with a osteotomy power device 6. In the present invention, an electric knife 7 and an aspirator 8 are provided in the telescopic column 3. Thus, the affected part can be incised and properly attracted according to the actual needs.

In connection with a preferred embodiment of the present invention, it is contemplated that stable bone cutting power may be provided independently during use. The upper end of the telescopic column 3 is connected with a bone cutting power device 6 through a fixed pipe 9. Meanwhile, the electric knife 7 and the aspirator 8 are connected with the fixed tube 9, a transmission channel 10 is arranged on one side of the fixed tube 9, and one ends of the electric knife 7 and the aspirator 8 are led out of the transmission channel 10. In this way, the electric knife 7 and the aspirator 8 are convenient to be connected with an external auxiliary device, and the electric knife 7 and the aspirator 8 can be ensured to float up and down synchronously with the telescopic column 3 while the telescopic column 3 floats up and down.

Further, in order to realize the structure that the nose device can clamp, one side of the nose connecting seat 1 of the invention is provided with a clamping piece 11 extending downwards, and the clamping piece 11 is provided with a main inscription line 12. Meanwhile, a working channel 13 extends below the telescopic column 3, and auxiliary scale marks 14 are arranged on the periphery of the working channel 13. Thus, the clip 11 and the lower end of the working channel 13 can form a clip configuration for subsequent positioning determination. And by means of the mutual matching of the main graduation line 12 and the auxiliary graduation line 14, effective machine head perpendicularity reference calibration can be met, and an accurate operation point is provided.

In view of practical implementation, in order to facilitate the operator to see a clear operation surface, effective manual intervention can be realized, and fine parameter adjustment is performed according to the current operation condition on the premise of autonomous operation of the robot, and an endoscope (not shown in the figure) can be additionally arranged on the telescopic column 3.

Still further, in order to be able to precisely indicate the current bone cutting depth, the present invention is provided with a hook-like formation 15 at the lower end of the electric knife 7.

In view of the fact that stable connection is realized with a preset operation platform of the surgical robot or an attached double-fork connecting device of the surgical robot, and convenient switching can be performed according to different surgical requirements, the machine head connecting seat 1 and the machine head fixing seat 16 can be locked by using the locking screw 17. Thus, convenient replacement and use can be realized. Of course, for different structures or implementation manners, screw, connecting rod, magnetic attraction and other manners may be adopted, but any structure that can realize the combination of the handpiece connecting seat 1 and the handpiece fixing seat 16 may be adopted, and will not be described herein. Meanwhile, the machine head connecting seat 1 can be directly connected with the robot in a butt joint manner in some extreme modes.

The working principle of the invention is as follows:

the spinous process of the human vertebra can be effectively clamped by forming a clip-like structure with the working channel 13 and the clamping piece 11. Thus, the left and right decompression bone groove can be positioned by using the spine edge as a reference. The control system of the spine minimally invasive surgery robot is installed through the tunnel type steel plate based on clamp type positioning, and the machine head device can rotate around the X axis by taking the top point of the clamping piece 11 as a fulcrum. In this way, the secondary graduation marks 14 on the working channel 13 to which the handpiece device belongs are kept coincident with the primary graduation marks 12 of the jaw 11. Thus, whether the handpiece is perpendicular to the bone (lamina surface) of the human body is judged. During operation, depending from the hook-like formation 15 of the electrotome 7, it may hook onto the lower surface of the bone (lamina). Thereby, the hook-like formation 15 of the electric knife 7 automatically indicates the depth of the cut bone.

In actual use, the end face of the cutter bar of the bone cutting power device 6 and the hook-shaped structure 15 at the end part of the electric cutter 7 can finally form a scissor shape, and the bone (vertebral lamina) is clamped so as to facilitate the automatic implementation of the operation of the bone opening groove decompression operation. And, since the handpiece has the upper extension spring 4 and the lower extension spring 5, when the handpiece rotates around the Y axis, for example, the lower surface of the bone (lamina) gets deep, the lower surface of the bone (lamina) presses the hook-shaped structure 15 of the electric knife 7, and the upper extension spring 4 and the lower extension spring 5 are compressed, and the hook-shaped structure 15 of the electric knife 7 is lowered. Otherwise, when the lower surface of the bone (lamina) becomes shallow, the upper 4 and lower 5 extension springs jack the hook-like formation 15 of the electric knife 7, causing the extension column 3 to automatically "float" upwards, with the hook-like formation 15 of the electric knife 7 rising. In this way, the hook-like structure 15 of the electrotome 7 can be always clung to the lower surface of the bone (lamina), and the change in height of the lower surface of the bone (lamina) can be automatically indicated. Thus, the cutter bar of the bone cutting power device 6 can safely and automatically cut out bone grooves on the vertebral lamina to realize decompression.
