Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic robot surgery, and in particular to a trunk fixing and protecting bracket based on an orthopedic surgical robot. Background Art

[0002] The application of orthopedic surgical robots is another leap forward in the development of orthopedic surgery towards intelligence, precision and minimally invasiveness. With the widespread application of surgical robots in orthopedic surgery, the accuracy and stability of the patient's position fixation during the operation have an increasingly greater impact on the surgical effect. During the operation, the orthopedic surgical robot needs to use advanced positioning and navigation systems to achieve high-precision positioning and operation of the patient's bones. Then, through advanced image tracking technology, the surgeon is assisted in assisting positioning and surgical operations during the operation. In the actual use of surgical robots, data recording and tracking are very important links. Any activity of the locator that locates the patient's body activities will cause errors in the computer's running trajectory (requires machine correction again). This requires that the patient's body position should be kept absolutely fixed during the operation as much as possible to avoid deviations in the surgical robot data tracking caused by the movement of the patient's body, which will affect the final surgical effect. At the same time, under intraoperative anesthesia, if the patient's body does not move for a long time, it will cause local pressure on the skin, resulting in poor blood circulation, limb numbness, skin pressure sores, etc. To this end, we propose a torso fixation protection brace based on orthopedic robotic surgery, which is mainly used to stably fix the patient's torso after the orthopedic robotic surgery to facilitate the tracking and positioning of the robot during the surgery. At the same time, the brace airbag and soft gel pad design ensure the safety and effectiveness during orthopedic robotic surgery.

[0003] This design is used for auxiliary fixation and protection of the torso during orthopedic robotic surgery. Summary of the invention

[0004] A technical problem to be solved by this application is to design a trunk fixation protection bracket that can effectively fix the patient's trunk during orthopedic surgery based on robot surgery to prevent the displacement of the trunk during surgery and affect the surgical effect, while avoiding limb numbness and skin pressure sores caused by long-term surgical fixation.

A plurality of trays 137 are arranged on the bracket body 1, and surgical instruments can be placed on the trays 137 during the operation.

[0048] When in use, if the patient feels discomfort in the chest or back, the airbag 13 supports the patient's chest, and the airbag 24 supports the patient's back. By manually pressing the pressing block 107 corresponding to the airbag 13 and the airbag 24, the pressing block 107 drives the rack 106 to slide, the rack 106 drives the gear 105 to rotate, and the gear 105 drives the driving shaft 102 to rotate synchronously with the storage roller 103, and drives the thin rope 104 to be wound around the storage roller 103, and the limiting block 123 on the rack 106 squeezes the limiting groove 122 on the locking block 121, driving the locking block 1 21 slides, at this time, the limit block 123 is engaged with the limit groove 122, and then the elasticity of the spring three 132 drives the locking block 121 to reset, and the limit block 123 is limited by the limit groove 122, the thin rope 104 pulls the U-shaped block 95, the U-shaped block 95 slides along the sliding seat 81, the U-shaped block 95 pulls the fixed column 94, and the fixed column 94 drives the first rotating shaft 91 and the second rotating shaft 92 to rotate through the telescopic rod 93, and the first rotating shaft 91 and the second rotating shaft 92 drive the first blocking block 82 and the second blocking block 83 to rotate and unfold synchronously, so that the first blocking block 82 and the second blocking block 83 are locked. 3. The blockage of the hollow cylinder 5 is released, and the push-type air pump 72 is manually squeezed. The push-type air pump 72 transmits the external gas into the hollow cylinder 5 through the air inlet branch pipe 71, and the gas then enters the airbag 1 3 or the airbag 2 4 from the one-way valve 62 in the hollow cylinder 5. When it is necessary to deflate the airbag 1 3 and the airbag 2 4, by pressing the pressure relief valve 64, the gas in the airbag 1 3 or the airbag 2 4 enters the air outlet branch pipe 63 through the deployed first blocking block 82 and the second blocking block 83, and is finally discharged from the pressure relief valve 64. When the airbag 1 3 and the airbag 2 4 are adjusted to a comfortable When the tension is loose, the unlocking block 133 is pressed, and the unlocking block 133 drives the guide column 131 and the locking block 121 to slide synchronously. The sliding of the locking block 121 drives the engagement of the limit groove 122 and the limit block 123 to be released, and the limit block 123 and the rack 106 are reset by the elasticity of the second spring 124, and the U-shaped block 95 is reset by the elasticity of the first spring 111. At this time, the first blocking block 82 and the second blocking block 83 rotate and block the hollow cylinder 5. At this time, pressing the pressure relief valve 64 and the push-type air pump 72 again will not change the air pressure inside the airbag 1 3 and the second airbag 4;

[0049] In addition, it should be noted that the airbag 24 can be provided in multiple quantities, and the small volume design can effectively increase the area of ​​the airbag, better protect the torso, and the small volume design is faster to inflate. Embodiment 2

[0050] See also Figure 12-13 , the present invention provides another technical solution:

[0051] Different from Example 1, a positioning shaft 14 is rotatably provided on the guide column 131, an unlocking block 133 is provided on the positioning shaft 14, two magnets 15 are provided on the trigger seat 101, a magnet 2 16 is provided on the positioning shaft 14, magnet 2 16 cooperates with magnet 1 15, and magnet 1 15 is slidably provided on the trigger seat 101.

[0052] When the patient is sleeping, by rotating the positioning shaft 14, the magnet 2 16 on the positioning shaft 14 and the magnet 1 15 attract each other, limiting the unlocking block 133, and then the locking block 121 is limited, so that the pressing block 107 cannot be pressed, and the first blocking block 82 and the second blocking block 83 will not rotate and unfold, thereby preventing the patient from accidentally squeezing the pressing air pump 72 or the pressure relief valve 64 while sleeping, causing the air pressure inside the airbag 1 3 or the airbag 2 4 to change. When it is necessary to release the limit on the locking block 121, the positioning shaft 14 is rotated to drive the magnet 2 16 on the positioning shaft 14 to attract the other magnet 15. At this time, the positioning shaft 14 together with the magnet 2 16 can slide on the trigger seat 101.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
