Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a collaborative orthopedic surgery tool auxiliary device and a collaborative method. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while trauma caused by traffic accidents has increased significantly. The changes in the spectrum of orthopedic injuries require orthopedics to keep pace with the times. Orthopedics is also known as orthopedic surgery. It is a specialty or discipline in medicine that specializes in the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system, as well as treat injuries and diseases of this system.

[0003] In existing orthopedic surgeries, surgical robots are often used to collaborate with and assist the surgeon in the orthopedic surgery. For example, patent application number: CN202311073132.2 discloses: a surgical robot for orthopedic surgery;

[0004] Although existing surgical robots have passed rigorous testing to ensure their positioning accuracy and ensure that the robot can accurately locate the part of the patient's surgery, for example, in existing pelvic fixation surgery, the auxiliary robot accurately locates the surgical tool to the surgical site and inserts it into the predetermined surgical site at a preset angle. However, during the operation, even if the patient is under deep anesthesia, the patient's breathing, heartbeat and the doctor's surgical operation will cause the patient's body to shake. Therefore, the doctor strictly monitors the patient's movement during the entire operation.

[0005] During this process, if the doctor is slightly distracted, the patient may move without being noticed, especially after the positioning sleeve of the auxiliary robot has been positioned. Since there is still a certain distance between the positioning sleeve and the actual surgical position, when the surgeon inserts the surgical tool into the patient's surgical position through the positioning sleeve, it is very easy for the patient to move without being observed, resulting in the deviation of the surgical tool and affecting the accuracy of the patient's surgery.

[0070] An adjusting member 55 for adjusting the extending position of the extending tube 51 is installed on the pushing sleeve 44 .

[0071] The adjusting member 55 includes an adjusting rod 551 penetrating through the pushing sleeve 44, the adjusting rod 551 is slidably connected to the pushing sleeve 44, and one end of the adjusting rod 551 is fixedly connected to the marking shell 54;

[0072] A fixed plate 552 is fixedly installed at one end of the push sleeve 44 located inside the hollow cavity 31, a fixed motor 553 is installed on the fixed plate 552, and an adjusting gear 554 is fixedly connected to the output end of the fixed motor 553;

[0073] The adjusting rod 551 is provided with a plurality of tooth grooves 5511 at equal intervals, and the adjusting gear 554 is meshedly connected with the tooth grooves 5511 .

[0074] There are multiple stabilizing components 6 , which are evenly distributed outside the supporting sleeve 3 , and the supporting sleeve 3 is provided with moving openings at positions corresponding to the stabilizing components 6 .

[0075] The stabilizing assembly 6 includes two connecting plates 61 fixedly mounted on the outer side of the moving port, a connecting shaft 62 is rotatably connected between the two connecting plates 61, a connecting gear 63 is fixedly sleeved on the outer side of the connecting shaft 62, and the connecting gear 63 is meshed and connected with the annular groove 441;

[0076] A contact claw 64 is fixedly mounted on the connecting gear 63, and a contact pad 65 is mounted on one end of the contact claw 64. The contact claw 64 in the present invention can be set in a retractable form or in an elastic form, so as to fix the periphery of the patient's surgical position.

[0077] Specific implementation process: After the positioning sleeve 2 is positioned by the mechanical arm 11 on the auxiliary robot 1, the positioning sleeve 2 moves to the set distance from the surgery, which is exactly the distance at which the marking block on the marking shell 54 moves to the position of the patient's surgery;

[0078] That is, the rotating motor 74 is running, thereby driving the outer gear ring 72 to rotate through the rotating gear 71, and when the outer gear ring 72 rotates, it synchronously drives the rotating sleeve 421 to rotate, and when the rotating sleeve 421 rotates, it provides driving force for the moving sleeve 422, and the moving sleeve 422 further moves along the inside of the hollow cavity 31 under the limiting action of the pushing sleeve 44, and when it moves, it synchronously drives the pushing sleeve 44 to move, and the pushing sleeve 44 makes the extension tube 51 extend synchronously with it, and when the extension tube 51 extends, the marking block at the marking shell 54 moves synchronously until the rotating motor 74 stops moving, and the marking block moves to the patient's surgical site, and makes a circular mark on the skin position outside the surgery, and when the marking is completed, the marking shell 54 can stay at the patient's surgical site, and a channel is formed between the marking shell 54 and the positioning sleeve 2 to assist the surgeon in inserting the surgical tool into the patient's surgical site;

[0079] When the marking is completed and the assistance of the marking shell 54 is not needed, the fixed motor 553 at the pushing sleeve 44 is operated, and the adjustment gear 554 is further operated. When the adjustment gear 554 rotates, it drives one end of the extension tube 51 to move along the inside of the liquid storage tube 52 through the adjustment rod 551, so as to achieve the function of retracting the marking shell 54, so as not to affect the surgical operation. When the extension tube 51 is retracted, it simultaneously compresses the liquid storage sponge inside the liquid storage tube 52, so as to introduce the marking liquid into it.

[0080] On the other hand, when the sleeve 44 is pushed to move, its outer annular groove 441 moves synchronously, thereby driving the multiple connecting gears 63 on the outside to rotate. When the multiple connecting gears 63 rotate, the contact claws 64 are driven to rotate, so that the multiple contact claws 64 fix the periphery of the patient's surgery, further preventing the patient from moving, and at the same time preventing the patient from moving relative to the positioning sleeve 2.

[0081] A collaborative method of a collaborative orthopedic surgery tool auxiliary device, comprising the following steps:

[0082] Step 1: When performing pelvic fixation surgery on a patient, first anesthetize the patient, and while anesthetizing, adjust the position of the auxiliary robot 1 and move it to the position where the patient needs surgery through the base;

[0083] Step 2: When the patient enters an anesthetized state, the auxiliary robot 1 uses the optical tracking camera on it to penetrate the epidermal tissue at the pelvis and identify the location of the required surgery. At this time, the controller controls the robot arm 11 to move the positioning sleeve 2 to the location of the required surgery.

[0084] Step 3: At this time, the pushing component 4 is in operation. When the pushing component 4 is in operation, the marking block is pushed to the surgical site of the patient, and contacts with the patient's skin and marks the skin. At the same time, the plurality of contact claws 64 fix the periphery of the surgical site of the patient through the contact pads 65.

[0085] Step 4: Then, the surgeon will position the cannula 2 and the marked position, and then accurately insert the surgical tools into the surgical position and perform the operation.

[0087] What is different from the first embodiment is that the support sleeve 3 is slidably sleeved on the outside of the positioning sleeve 2, and two threaded holes are provided on the support sleeve 3, and positioning bolts 32 are threadedly connected to the two threaded holes. The support sleeve 3 is detachably mounted on the outside of the positioning sleeve 2 through the positioning bolts 32, so that when in use, the support sleeve 3 is inserted from the bottom of the positioning sleeve 2. When the top of the support sleeve 3 contacts the positioning sleeve 2, it only needs to rotate the positioning bolts 32 to achieve the locking and fixing effect between the support sleeve 3 and the positioning sleeve 2.

[0089] Different from the first embodiment, the driving member 42 includes two positioning plates 45 fixedly installed inside the hollow cavity 31, one end of the positioning plate 45 is fixedly connected to an electric push rod 46, one end of the two electric push rods 46 are fixedly connected to the pushing ring 41, so that when the pushing sleeve 44 is pushed, the two electric push rods 46 operate. At this time, one end of the pushing sleeve 44 moves along the hollow cavity 31 to the outside of the positioning sleeve 2, so that the electric push rod 46 is adopted, and the pushing of the pushing sleeve 44 can be more convenient and quick.

[0090] See also Fig.12 , Embodiment 4

[0091] Further supplementing the first embodiment is that a sealing disinfection cover 541 is clamped on the outer side of the marking shell 54. When the auxiliary robot 1 is not in use, the sealing disinfection cover 541 is manually installed on the outer side of the marking shell 54, thereby sealing the marking shell 54 and preventing the marking liquid in the marking block inside the marking shell 54 from volatilizing.
