[0002] In scenarios such as intraoperative positioning and navigation of orthopedic surgical robots, precise guidance of neurosurgical minimally invasive surgical robots, real-time path planning of laparoscopic interventional robots, and spatial positioning and scheduling of rehabilitation and nursing robots, positioning and navigation devices used in medical robots are often required to control the positioning and navigation accuracy, intraoperative real-time response speed, multimodal image registration accuracy, spatial anti-interference stability, adaptability to different surgical procedures, ease of operation and interaction, and traceability of navigation data.

[0003] Existing positioning and navigation devices used in medical robots have significant deficiencies in positioning and navigation accuracy, deployment cleanliness, and intraoperative surgical field stability. In the positioning and deployment and intraoperative navigation of medical robot surgery, they usually adopt a single optical or electromagnetic positioning scheme, which has a mediocre positioning effect and cannot effectively provide accurate positioning, making it difficult to meet the positioning and navigation requirements of high-precision and high-cleanliness surgical robots.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a positioning and navigation device for medical robots. The positioning and navigation device for medical robots includes a mounting component 1 and an auxiliary positioning component 2.

[0032] By coordinating the design of the installation component 1 and the auxiliary positioning component 2, the shortcomings of existing positioning and navigation devices used in medical robots, such as low positioning and navigation accuracy, poor deployment cleanliness, and insufficient stability of the surgical field during surgery, are solved. The implementation scheme of single optical positioning or electromagnetic positioning is abandoned. The pre-operative purging can be completed simultaneously during the installation and locking of the positioning device to remove the packaging bag fibers attached to the surface. At the same time, it provides a stable auxiliary purging effect during surgery to maintain the clarity of the surgical field. It avoids the positioning drift and accuracy decay problems caused by environmental interference such as blood and instruments obstructing the view during surgery by single positioning methods, thus ensuring the operational accuracy of the medical robot and the safety of the surgery.

[0033] Specifically, the mounting component 1 includes a mounting handle 11, one side of which has a connecting spline groove 12, and the other side of which is fixed with a connecting support rod 13.

[0034] Specifically, the auxiliary positioning component 2 is located on the outside of the mounting component 1, including a mounting member 21 embedded in the inner wall of the connecting support rod 13, a positioning member 24 movably connected to the inner wall of the mounting member 21, a gas transmission member 22 fixed to one side of the mounting member 21, a purging member 23 sleeved on the surface of the connecting support rod 13, an intermediate gas storage member 25 installed on the surface of the mounting member 21, and a transmission member 26 installed on the surface of the mounting handle 11.

[0035] Example 2, refer to Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the mounting component 21 includes a fixed seat 211 embedded in the inner wall of the connecting support rod 13, a pneumatic housing 212 fixed to one side of the fixed seat 211, a compression piston 214 slidably connected to the inner wall of the fixed seat 211 and the pneumatic housing 212, a one-way air supply hose 216 fixed to one side of the pneumatic housing 212, a first return spring 215 fixed to the inner wall of the pneumatic housing 212, a mounting cylinder 213 mounted on one side of the fixed seat 211, and a transmission plate 217 fixed to the inner wall of the mounting cylinder 213.

[0037] Mounting component 21 provides a front-end triggered air source generation function for the entire air circuit system. The fixing base 211 is embedded in the inner wall of the connecting support rod 13 to achieve concealed installation. A one-way air replenishment valve is installed on one side of the mounting component 21, which can replenish air inside when needed. The air drive shell 212 and the fixing base 211 together form a sealed air chamber, providing space for gas compression. When the external component extends into the mounting cylinder 213, it squeezes the transmission plate 217, pushing the compression piston 214 to slide along the inner wall of the chamber to compress the internal air and generate compressed airflow. The first return spring 215 provides a return spring force for the compression piston 214. After the external force is removed, it drives the piston to return to its position automatically. The one-way air delivery hose 216 delivers the high-pressure gas generated by compression to the subsequent air circuit components in one direction, avoiding gas backflow that affects the stability of the air supply.

[0038] Specifically, the gas transmission component 22 includes an elastic airbag 221 fixed to the top of the mounting cylinder 213, and a transverse connecting tube 223 is fixed to the surface of the elastic airbag 221.

[0039] Specifically, a support sleeve 222 is fitted on one side of the transverse connecting pipe 223, and the support sleeve 222 is fixed to the surface of the mounting component 21.

[0040] Specifically, the purging component 23 includes a fixing ring 231 sleeved on the surface of the connecting support rod 13, a support frame 232 fixed on the surface of the fixing ring 231, a fixing screw 233 fixed on the surface of the support frame 232, a connecting screw sleeve 234 sleeved on one side of the fixing screw 233, an air storage arc tube 235 movably connected to one side of the connecting screw sleeve 234, and an air blowing nozzle 236 embedded in the inner wall of the air storage arc tube 235.

[0041] The blowing component 23 achieves circumferential airflow cleaning of the connecting support rod 13. Multi-angle blowing can be achieved by rotating the air storage arc tube 235. During initial installation, it is rotated to the limit angle so that it blows on the surface of the auxiliary positioning component 2. During the operation, the surgical field can be cleaned by blowing air from the initial position. The fixing ring 231 is fitted onto the surface of the connecting support rod 13 to form an installation reference. The support frame 232 provides external support for the blowing structure. The fixing screw 233 and the connecting screw sleeve 234 cooperate to adjust and lock the angle of the air storage arc tube 235. The blowing angle can be adjusted according to the blowing needs. The air storage arc tube 235 is arranged circumferentially to form a surrounding air cavity, and the airflow is evenly distributed to each blowing nozzle 236. Multiple sets of blowing nozzles 236 spray airflow in a directional manner to blow on the surgical field for clear display.

[0042] Specifically, the purging component 23 also includes a vent pipe 237 disposed on one side of the gas transmission component 22. The vent pipe 237 is fixed to one side of the gas storage arc pipe 235 and is installed on the top of the fixing ring 231.

[0043] The vent pipe 237 delivers the pressure-stabilized airflow output from the gas transmission component 22 to the interior of the gas storage arc pipe 235, providing a continuous air source for the purging action. The fixing ring 231 provides an installation base for the vent pipe 237 and other structures.

[0044] Specifically, the positioning component 24 includes a connecting seat 245 movably connected to the inner wall of the mounting component 21. A rotating slot 247 is provided on the surface of the connecting seat 245, and a guide slot 246 is provided on one side of the rotating slot 247.

[0045] Positioning component 24 enables quick insertion and positioning of functional components and angle locking. Connecting base 245 is embedded in the inner wall of mounting component 21 to form an insertion reference. Guide slot 246 provides axial guide for insertion components, reducing the difficulty of insertion and alignment. Rotary slot 247 is connected to guide slot 246. After insertion, rotation will lock the component into the rotary slot 247, achieving axial locking and preventing the component from being dislodged by external force.

[0046] Specifically, the positioning component 24 also includes an optical signal positioner 241 fixed to one side of the connecting seat 245, a positioning protrusion 243 installed on one side of the optical signal positioner 241, an electromagnetic positioning module 248 fixed to the surface of the optical signal positioner 241, and a positioning groove 244 formed on the surface of the optical signal positioner 241.

[0047] The optical signal locator 241 outputs an optical positioning signal to achieve precise alignment guidance during the insertion process. The positioning protrusion 243 and the positioning groove 244 achieve bidirectional functional positioning. That is, when the positioning protrusion 243 faces outward, it is in the surgical demonstration state, and the device automatically records the surgery after positioning detection. When the positioning groove 244 faces outward, it is in the normal surgical state, and the device realizes automatic positioning and detection functions. The electromagnetic positioning module 248 generates an electromagnetic field after being inserted into place, realizing the magnetic field positioning function. The overall positioning accuracy is further improved through the dual positioning mode.

[0048] Specifically, the intermediate gas storage component 25 includes a gas storage shell 251 fixed to the surface of the mounting component 21, a drive piston 252 slidably connected to the inner wall of the gas storage shell 251, a connecting slide rod 254 fixed to one side of the drive piston 252, a transmission ball 255 fixed to one side of the connecting slide rod 254, a second return spring 253 sleeved on the surface of the connecting slide rod 254, a one-way pressure relief pipe 256 fixed to one side of the gas storage shell 251 and the surface of the gas transmission component 22, and a pressure relief and gas delivery pipe 257 fixed to one side of the gas storage shell 251 and the surface of the purging component 23.

[0049] The intermediate gas storage unit 25 realizes the pressure stabilization and energy storage of the gas path and the quantitative pressure relief and gas supply. The gas storage shell 251 provides a sealed space for gas storage and piston movement. When the pressure of the front gas path increases, the one-way pressure relief pipe 256 is automatically opened. The high-pressure gas in the gas storage shell 251 is delivered to the purging unit 23 through the pressure relief and gas delivery pipe 257 to provide an instantaneous high-flow purging gas source. When the gas pressure decreases, the second return spring 253 pushes the drive piston 252 to return to its original position, maintaining the gas path pressure stability and realizing the dual functions of continuous pressure stabilization and gas supply and instantaneous strong purging.

[0050] Example 3, referring to Figures 2-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the transmission component 26 includes a shaped fixing block 261 fixed to the surface of the mounting handle 11, a support bearing sleeve 262 mounted on one side of the mounting handle 11, a rotating shaft 265 movably connected to the inner wall of the support bearing sleeve 262, a fourth bevel gear 268 fixed to one end of the support bearing sleeve 262, a pressing cam 266 movably connected to one side of the shaped fixing block 261, a rotating knob 264 movably connected to the surface of the shaped fixing block 261, a second bevel gear 263 sleeved on the surface of the rotating knob 264, and a third bevel gear 267 sleeved on the surface of the pressing cam 266.

[0052] When in use, to enable the normal surgical positioning detection mode, align the connecting seat 245 of the positioning component 24 with the inner cavity of the mounting cylinder 213, insert it horizontally into place along the guide direction of the guide slot 246, and then rotate the positioning component 24 clockwise so that the locking pin of the connecting seat 245 slides into the inner cavity of the rotating slot 247 to complete axial locking. At this time, the positioning groove 244 faces outward, and the device automatically recognizes and switches to the normal surgical state, enabling the real-time positioning detection function. To enable the surgical demonstration recording mode, after inserting it into place, rotate the positioning component 24 counterclockwise to complete locking. At this time, the positioning protrusion 243 faces outward, and the device automatically switches to the demonstration recording state, automatically recording the surgical process simultaneously with the positioning detection. The plug-in rotary installation requires no additional fasteners, is convenient to operate and has reliable locking, and can quickly switch between two working modes to adapt to different clinical scenario needs.

[0053] During the insertion and advancement of the positioning component 24, the end of the connecting seat 245 extends into the mounting cylinder 213 and presses the transmission plate 217 inward, pushing the compression piston 214 to slide synchronously along the inner wall of the fixed seat 211 and the air drive housing 212, compressing the first return spring 215 to store energy, and at the same time compressing the air inside the air chamber to form a high-pressure airflow; the high-pressure gas is unidirectionally delivered to the elastic airbag 221 of the gas transmission component 22 through the one-way air delivery hose 216, and the elastic airbag 221 expands under air pressure, uniformly hugging the outer side of the connecting seat 245 from the circumference. The wall eliminates the gap between the insertion and mating parts, improves the installation tightness and coaxiality of the positioning component 24, and avoids positioning drift caused by loosening of components during the operation; when the air pressure in the elastic airbag 221 reaches the set threshold, the excess gas is automatically filled into the air storage shell 251 of the intermediate air storage component 25 through the transverse connecting pipe 223 and the one-way pressure relief pipe 256 for temporary storage, pushing the drive piston 252 to slide inward to compress the second reset spring 253 to complete energy storage. The entire installation process is completed automatically and synchronously with the clamping reinforcement and air source reserve, without the need for additional external air circuits and manual operation.

[0054] After the positioning component 24 is installed and locked, loosen the connecting screw sleeve 234, manually rotate the air storage arc tube 235 to the limit angle, so that the air blowing nozzle 236 is aligned with the surface of the optical signal positioner 241 and the electromagnetic positioning module 248, and tighten the connecting screw sleeve 234 to lock the blowing angle; then rotate the rotation knob 264 of the transmission component 26 to drive the second bevel gear 263 to rotate synchronously, and through the step-by-step meshing transmission of the fourth bevel gear 268, the rotating shaft 265, and the third bevel gear 267, drive the extrusion cam 266 to rotate around the shaft; the protruding contour of the extrusion cam 266 extrudes... The pressure-driven ball 255 pushes the drive piston 252 to slide along the inner wall of the gas storage shell 251 via the connecting slide rod 254, instantly compressing the gas stored inside. The high-pressure gas is transported to the gas storage arc tube 235 through the pressure relief and gas supply pipe 257 and the vent pipe 237. The gas is then blown out in a direction by multiple sets of air blowing nozzles 236 to blow away the packaging bag fibers, dust and other impurities attached to the surface of the optical signal locator 241, ensuring that the transmission and reception of the optical positioning signal are not blocked, avoiding the impact of pollutants on the positioning accuracy during deployment, and ensuring the cleanliness and accuracy of the initial positioning reference.

[0055] During the surgery, the optical signal locator 241 continuously outputs optical positioning signals, while the electromagnetic positioning module 248 is simultaneously powered on to generate an electromagnetic field for magnetic field positioning, forming a dual positioning system of optical and electromagnetic. The data from both systems can compensate and correct each other, avoiding the problems of positioning drift and accuracy decay caused by environmental interference such as blood and instruments obstructing the view during surgery when using a single positioning method. This provides stable and accurate navigation coordinates for the medical robot, ensuring the precision of the surgical operation and clinical safety.

[0056] If blood or fog accumulates in the surgical field during the operation, affecting the clarity of the field of vision, the rotary knob 264 can be turned again. The same bevel gear transmission path drives the compression cam 266 to rotate, intermittently compressing the drive piston 252 to release the stabilizing airflow in the gas storage shell 251. The airflow is then blown into the surgical field through the blowing nozzle 236 to disperse local fog and flush away surface blood and fluid accumulation, maintaining the clarity of the surgical field. No additional handheld blowing equipment is required, reducing the risk of personnel movement and contamination during the operation. The second reset spring 253 can push the drive piston 252 to reset after the cam lift is released, and automatically replenishes gas through the one-way air path to reserve gas source for the next blowing, realizing multiple blowing as needed.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
