[0052] There are currently no surgical robots with front-end diagnostic and treatment switching capabilities in the relevant technologies, making it quite cumbersome for doctors to operate during surgery.

[0053] Please refer to the diagnostic and therapeutic interchange front-end 100 provided in the first aspect embodiment of the present invention. Figures 1 to 7 It includes a housing 102, a turntable assembly 110, an instrument base 120, and a telescopic assembly 130.

[0054] The shell 102 is an elliptical or circular columnar structure. The size and outline of the shell 102 are adapted to the cavities inside the human body. When the shell 102 comes into contact with human tissue, it will not cause pain or abrasion.

[0055] The housing 102 includes opposing front and rear ends, the rear end being adapted to connect to the flexible drive assembly 300, and the front end being able to extend different diagnostic and therapeutic instruments to achieve different operations.

[0056] A sealed receiving cavity 104 is formed inside the housing 102, and an instrument channel 106 communicating with the receiving cavity 104 is formed at the front end of the housing 102. When the diagnostic and therapeutic instrument 200 is placed in the receiving cavity 104, the diagnostic and therapeutic instrument 200 can extend along the instrument channel 106.

[0057] In some embodiments, a light-transmitting hole is also formed at the front end of the housing 102, which is used to provide illumination or emit laser light inside the human body.

[0058] The turntable assembly 110 is disposed within the receiving cavity 104. The turntable assembly 110 includes a turntable 112, on which a plurality of positioning holes 114 are formed. The turntable 112 is parallel to the front end face of the housing 102. The turntable assembly 110 can precisely control the rotation of the turntable 112, and any one of the plurality of positioning holes 114 can be aligned with the instrument channel 106.

[0059] There are multiple instrument seats 120, and each instrument seat 120 is inserted into a multiple positioning hole 114 in a one-to-one correspondence. The side of the instrument seat 120 facing the instrument channel 106 is suitable for installing the diagnostic and therapeutic instrument 200, and the side of the instrument seat 120 facing away from the instrument channel 106 is suitable for connecting to the telescopic assembly 130.

[0060] The telescopic assembly 130 is disposed in the receiving cavity 104, located on the side of the turntable 112 away from the instrument channel 106, and the position of the telescopic assembly 130 corresponds to the position of the instrument channel 106.

[0061] According to the diagnostic and therapeutic interchangeable front end provided in the embodiment of the present invention, the turntable assembly 110 can make different positioning holes 114 correspond to the instrument channel 106. When the telescopic assembly 130 extends, it can drive the instrument seat 120 closer to the instrument channel 106. At the same time, the diagnostic and therapeutic instruments 200 mounted on the instrument seat 120 extend along the instrument channel 106. After use, the telescopic assembly 130 retracts, and the instrument seat 120 falls back into the positioning hole 114. At this time, other diagnostic and therapeutic instruments 200 can be switched. By controlling the operation of the turntable assembly 110 and the telescopic assembly 130, the automatic switching of different diagnostic and therapeutic instruments 200 can be realized at the front end of the housing 102, which has rich functions and improves the convenience of doctors during surgical operations.

[0062] In some embodiments, the turntable assembly 110 further includes a first motor 116 and a drive shaft 118. The first motor 116 is disposed within the receiving cavity 104, and the drive shaft 118 is connected to the center of the turntable 112. When the drive shaft 118 rotates, the turntable 112 rotates synchronously. The drive shaft 118 is connected to the output shaft of the first motor 116 via a gear 117. By controlling the first motor 116, the rotation angle and rotation direction of the turntable 112 can be adjusted, thereby allowing different diagnostic and therapeutic instruments 200 to correspond to the instrument channel 106.

[0063] In some embodiments, the telescopic assembly 130 includes a second motor 132, a lead screw 134, a lead screw sleeve 136, and a lead screw sleeve limiting member 138.

[0064] The second motor 132 is disposed in the receiving cavity 104, and the lead screw 134 is rotatably connected to the cavity wall of the receiving cavity 104. The output shaft of the second motor 132 is connected to the lead screw 134 through a gear, and the center of the lead screw 134 corresponds to the center of the instrument channel 106.

[0065] The lead screw sleeve 136 is rotatably connected to the lead screw 134. When the lead screw 134 rotates, the lead screw sleeve 136 rotates relative to the lead screw 134. At the same time, the lead screw sleeve 136 moves toward or away from the instrument channel 106.

[0066] The lead screw sleeve limiting member 138 is disposed on the outside of the lead screw sleeve 136 and is used to limit the rotation of the lead screw sleeve 136.

[0067] It is understandable that controlling the rotation direction and angle of the second motor 132 can precisely control the distance by which the lead screw sleeve 136 extends or retracts.

[0068] When the lead screw sleeve 136 extends, the end of the lead screw sleeve 136 is connected to the instrument seat 120, which can bring the instrument seat 120 close to the instrument channel 106. At this time, the diagnostic and therapeutic instruments 200 on the instrument seat 120 extend along the instrument channel 106.

[0069] When the lead screw sleeve 136 retracts, the end of the lead screw sleeve 136 is connected to the instrument seat 120, and the instrument seat 120 can be put back into the positioning hole 114. When the lead screw sleeve 136 continues to retract, the end of the lead screw sleeve 136 is disengaged from the instrument seat 120, and the operation can be terminated or other diagnostic and treatment instruments 200 can be switched.

[0070] In some embodiments, a cavity is formed within the lead screw sleeve limiting member 138, and a guide groove 1380 is formed on the cavity wall, extending toward the direction of the instrument channel 106. A protrusion 1360 is provided on the outer wall of the lead screw sleeve 136, and the protrusion 1360 is slidably connected to the guide groove 1380.

[0071] Understandably, the guide groove 1380 restricts the rotation of the lead screw sleeve 136. When the lead screw 134 rotates, the lead screw sleeve 136 moves away from or closer to the instrument channel 106 along the guide groove 1380 in the cavity. The guide groove 1380 increases the stability of the lead screw sleeve 136 during movement.

[0072] In some embodiments, the guide groove 1380 includes a first guide portion 1382, a second guide portion 1384, and a third guide portion 1386 connected in sequence, wherein the first guide portion 1382 and the third guide portion 1386 are arranged in the same direction, the second guide portion 1384 is perpendicular to the first guide portion 1382 and the third guide portion 1386, and the second guide portion 1384 is located between the first guide portion 1382 and the third guide portion 1386.

[0073] The instrument base 120 has a sliding groove 122 formed on its side wall. The sliding groove 122 includes a first sliding portion 124 and a second sliding portion 126, with the first sliding portion 124 communicating with the second sliding portion 126. The first sliding portion 124 and the third guide portion 1386 are arranged in the same direction, as are the second sliding portion 126 and the second guide portion 1384. The first sliding portion 124 extends to the edge of the instrument base 120 facing the turntable 112. A slider 1140 is provided on the wall of the positioning hole 114, and the slider 1140 is adapted to fit the sliding groove 122.

[0074] When the lead screw 134 is rotated, the protrusion 1360 moves along the first guide portion 1382 and approaches the instrument channel 106. When the protrusion 1360 reaches the second guide portion 1384, the end of the lead screw sleeve 136 abuts against the instrument seat 120 and engages with the instrument seat 120.

[0075] As the lead screw 134 continues to rotate, the protrusion 1360 slides within the second guide portion 1384, and the lead screw sleeve 136 rotates relative to the lead screw sleeve limiting member 138. At this time, the instrument seat 120 rotates synchronously, and the slider 1140 moves along the second sliding portion 126 and approaches the first sliding portion 124.

[0076] As the lead screw 134 continues to rotate, the protrusion 1360 moves along the third guide portion 1386 closer to the instrument channel 106, and the slider 1140 slides out along the first sliding portion 124, thereby unlocking the instrument seat 120.

[0077] As the lead screw 134 continues to rotate, the protrusion 1360 approaches the instrument channel 106 along the third guide 1386, and the lead screw sleeve 136 and the instrument seat 120 simultaneously approach the instrument channel 106. The diagnostic and therapeutic instrument 200 extends along the instrument channel 106 for the doctor to operate.

[0078] Reversing the lead screw sleeve 136 retracts the diagnostic instrument 200, allowing the instrument seat 120 to enter the positioning hole 114. The slider 1140 then moves along the first sliding part 124 into the second sliding part 126, locking the instrument seat 120.

[0079] After locking the instrument seat 120, when switching to the diagnostic instrument 200, the other instrument seats 120 are in a stable state and will not loosen or fall off.

[0080] To enhance the locking effect of the instrument seat 120, the friction between the slider 1140 and the second sliding part 126 is relatively large. An elastic structure or a damping structure can be provided to prevent the instrument seat 120 from becoming loose or slipping.

[0081] In some embodiments, the adjacent end faces of the instrument seat 120 and the lead screw sleeve 136 are provided with a first plug-in structure 128 and a second plug-in structure 1362 that match each other. For example, the first plug-in structure 128 is provided on the end face of the instrument seat 120, and the second plug-in structure 1362 is provided on the end of the lead screw sleeve 136.

[0082] It should be noted that there is friction between the first plug-in structure 128 and the second plug-in structure 1362. After the first plug-in structure 128 is connected to the second plug-in structure 1362, there is no relative rotation between the instrument seat 120 and the lead screw sleeve 136.

[0083] In some embodiments, the first insertion structure 128 is a sleeve, and the second insertion structure 1362 is a boss. When the boss is inserted into the sleeve, the instrument seat 120 and the lead screw sleeve 136 are stably connected.

[0084] The side of the instrument holder 120 facing the instrument channel 106 is suitable for mounting the diagnostic and therapeutic instruments 200. Multiple instrument holders 120 can mount a variety of diagnostic and therapeutic instruments 200 to achieve the diversity of functions of the diagnostic and therapeutic interchangeable front end.

[0085] The inner wall of the sleeve is provided with multiple first annular electrodes, and the outer wall of the boss is provided with multiple second annular electrodes 1364. When the boss is inserted into the sleeve, the multiple first annular electrodes and the multiple second annular electrodes 1364 are connected one-to-one to realize the identification, power supply and signal transmission of the diagnostic and therapeutic device. The number of first annular electrodes and second annular electrodes 1364 is determined according to the function to be performed.

[0086] According to the embodiments of the present invention, the diagnostic and therapeutic interchangeable front end, the diagnostic and therapeutic instrument, the instrument base 120 and the first plug-in structure 128 form a modular structure, which can realize a variety of diagnostic and therapeutic functions, such as lighting, flushing, suction, mechanical cutting and laser treatment.

[0087] When the turntable assembly 110 rotates, the modular structure enables intelligent automatic switching, improving the convenience of in vivo diagnosis and treatment.

[0088] It should be noted that the second annular electrode 1364 can be a flexible structure. The flexible structure is conducive to the installation and disassembly of the boss and the sleeve, and at the same time helps to ensure the tightness of the connection between the first annular electrode and the second annular electrode 1364, avoiding poor contact.

[0089] When the lead screw sleeve 136 approaches the instrument seat 120, the boss inserts into the sleeve, and the boss can drive the sleeve and the instrument seat 120 to rotate synchronously, thereby unlocking the instrument seat 120.

[0090] When the lead screw sleeve 136 moves away from the instrument seat 120, the boss drives the sleeve and the instrument seat 120 to rotate, causing the slider 1140 to slide into the second sliding part 126, thereby locking the instrument seat 120.

[0091] In some embodiments, a motor fixing member 1042 is provided in the receiving cavity 104, and a mounting groove 1044 is formed in the motor fixing member 1042. A first motor 116 and a second motor 132 are disposed in the mounting groove 1044, and the output shafts of the first motor 116 and the second motor 132 are arranged in opposite directions.

[0092] The motor fixing component 1042 increases the positional stability of the first motor 116 and the second motor 132, which not only makes the position switching of the turntable 112 more stable, but also makes the extension and retraction movement of the lead screw sleeve 136 more stable.

[0093] The output shafts of the first motor 116 and the second motor 132 are set in opposite directions, which makes the layout of the turntable assembly 110 and the telescopic assembly 130 more reasonable and reduces the size of the diagnostic and treatment interchange front end.

[0094] In some embodiments, the motor fixing member 1042 and the lead screw sleeve limiting member 138 are connected by a support member 108. The support member 108 increases the structural strength of the housing 102, the motor fixing member 1042 and the lead screw sleeve limiting member 138, thereby improving the positional accuracy of the diagnostic and therapeutic device 200.

[0095] The support member 108 forms a limiting hole 1082, and the drive shaft 118 is rotatably connected to the limiting hole 1082. The limiting hole 1082 increases the stability of the turntable 112 when it rotates.

[0096] For a medical robot provided according to a second aspect embodiment of the present invention, please refer to [link / reference needed]. Figure 8 It includes at least one flexible drive component 300 and a diagnostic and therapeutic interchangeable front end 100 provided according to a first aspect embodiment of the present invention, wherein the diagnostic and therapeutic interchangeable front end 100 is connected to the flexible drive component 300 and the instrument channel 106 of the diagnostic and therapeutic interchangeable front end is away from the flexible drive component 300.

[0097] The flexible drive component 300 can perform actions such as bending, rotating, stretching, or compressing. The diagnostic and therapeutic interchangeable front end 100 is connected to the flexible drive component 300 and can be inserted deep into the human body to perform minimally invasive surgery.

[0098] It should be noted that there can be multiple flexible drive components 300. When multiple flexible drive components 300 are connected in sequence, they can adapt to the complex cavity structure inside the human body, which is beneficial for sending the diagnostic and therapeutic interchangeable front end 100 into the target position.
