[0040] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0043] In the present invention, unless otherwise clearly specified or defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The present invention provides a surgical robot, which includes a main operation console and a slave operation device. The main operation console is used to send control commands to the slave operation device according to the operations of a doctor to control the slave operation device; the slave operation device is used to respond to the control commands sent by the main operation console and perform corresponding surgical operations. The slave operation device includes a robotic arm, a power mechanism arranged on the robotic arm, and an operating arm. The operating arm is used to extend into the body under the driving action of the power mechanism, perform surgical operations through the end effector located at its distal end, and acquire in-vivo images through the electronic endoscope located at its distal end. The main operation console is also used to display the images acquired by the electronic endoscope.

[0046] Such as Figure 1As shown in the figure, the present invention provides an electronic endoscope 100, which can be a flexible structure or an inflexible structure. The electronic endoscope 100 may include a handle portion 1, a body portion 2, and an adapter assembly 3 detachably connected to the handle portion 1 and the body portion 2 at both ends. An image acquisition portion (not shown in the figure) is provided on one side of the body portion 2 away from the handle portion 1. Through the image acquisition portion, during minimally invasive surgery, an image of the patient's lesion area can be clearly obtained, thereby helping the doctor to accurately perform surgical operations. And the body portion 2 can control the switch of the electronic endoscope 100 and the adjustment of image parameters, etc. In other embodiments, the adapter assembly 3 may be fixedly connected to the handle portion 1, and the adapter assembly 3 is detachably connected to the body portion 2; or the adapter assembly 3 is fixedly connected to the body portion 2, and the adapter assembly 3 is detachably connected to the handle portion 1. That is, the adapter assembly 3 is fixed to one of the handle portion 1 or the body portion 2, or the adapter assembly 3 and the handle portion 1 or the body portion 2 are of an integral structure.

[0047] Among them, the manner in which the two ends of the adapter assembly 3 are detachably connected to the handle portion 1 and the body portion 2 respectively may include: rotational connection, snap connection, magnetic attraction, etc.

[0048] In one embodiment, as Figure 2 shown, the adapter assembly 3 may further include a rotating member 31 and an intermediate portion 32 provided inside the rotating member 31. The rotating member 31 can rotate relative to the intermediate portion 32. Among them, the intermediate portion 32 is detachably connected to the handle portion 1, and the rotating member 31 is detachably connected to the body portion 2. In other embodiments, the intermediate portion 32 may also be detachably connected to the body portion 2, and the rotating member 31 is detachably connected to the handle portion 1.

[0049] In one embodiment, as Figure 2 shown, the rotating member 31 may further include a self-locking rotating portion 35 and a fixing portion 36 fixedly cooperating with the self-locking rotating portion 35. The fixing manner between the self-locking rotating portion 35 and the fixing portion 36 may be: threaded connection, snap connection, magnetic attraction, or adhesion, etc. In this embodiment, the intermediate portion 32 is located between the self-locking rotating portion 35 and the fixing portion 36. Among them, the intermediate portion 32 is detachably connected to the handle portion 1, and the fixing portion 36 is detachably connected to the body portion 2. In other embodiments, the intermediate portion 32 is detachably connected to the body portion 2, and the fixing portion 36 is detachably connected to the handle portion 1.

[0050] Further, as Figure 3As shown, the self-locking rotating part 35 may include a body 351 and an elastic part 352 fixed to the body 351. Specifically, the elastic part 352 may be an elastic and retractable structure such as a spring. The elastic part 352 has a first end 353 fixed to the body 351 and a second end 354 disposed opposite to the first end 353, and the second end 354 may be a free end. In other embodiments, the self-locking rotating part 35 may further include a mounting part 355 protruding from the body 351, and the first end 353 of the elastic part 352 is fixed to the mounting part 355.

[0051] Furthermore, as Figure 3 shown, the self-locking rotating part 35 may further include a first limiting part 356 protruding from the body 351. The size of the first limiting part 356 may be the same as that of the elastic part 352. In other embodiments, the first limiting part 356 may also protrude along the circumference of the body 351. It can be understood that in order to improve the fixing strength of the mounting part 355, the mounting part 355 may be connected to the first limiting part 356. When the elastic part 352 elastically deforms, the first limiting part 356 may limit the elastic part 352 from moving towards the handle part 1. The cooperation between the first limiting part 356 and the middle part 32 will be specifically described below. It can be understood that the elastic deformation of the elastic part 352 may include elastic contraction or elastic recovery.

[0052] Furthermore, as Figure 3 shown, the middle part 32 includes an intermediate body 321 and one or more blocking bodies 322 protruding from the intermediate body 321. When the mounting part 355 abuts against the blocking body 322 close to the first end 353, the elastic force of the elastic part 352 is greater than or equal to zero. That is, the elastic part 352 may still retain a certain elastic force before elastically deforming when abutting against the blocking body 322, or the elastic part 352 may be in a natural state without elastic force. It can be understood that when the elastic part 352 still has a certain elastic force when elastically recovering between the two blocking bodies 322, the blocking body 322 abutting against the mounting part 355 can play a limiting role, so that the mounting part 355 moves relatively within the space limited by the two blocking bodies 322.

[0053] In one embodiment, the middle part 32 includes two adjacent blocking bodies 322, and the elastic part 352 is located between the two blocking bodies 322. In other embodiments, as Figure 3As shown, the middle part 32 further includes a second limiting part 323 protruding from the middle body 321, and the second limiting part 323 is used to limit the elastic part 352 from moving away from the handle part 1 when the elastic part 352 is elastically deformed. The second limiting part 323 can be located between the two blocking bodies 322, in which case the overall weight of the adapter assembly 3 can be reduced; the second limiting part 323 can also be protruding along the periphery of the middle body 321, in which case the overall structural strength of the middle part 32 can be improved. The middle body 321 can be a hollow cylindrical shape, and the blocking body 322 is a protruding structure protruding outward from the outer surface of the middle body 321. Of course, in other embodiments, the middle body 321 can also be other shapes, and the blocking body 322 can also be a protruding structure protruding inward from the inner surface of the middle body 321. The body 351 can be a structure that matches the shape of the middle body 321, for example, it can also be a hollow cylindrical shape.

[0054] It is understandable that when the size of the intermediate body 321 and the main body 351 match, the first limiting portion 356 only limits the elastic portion 352 from moving toward the handle portion 1 when the elastic portion 352 is elastically deformed; the second limiting portion 323 only limits the elastic portion 352 from moving away from the handle portion 1 when the elastic portion 352 is elastically deformed. When the size of the intermediate body 321 and the main body 351 are different, for example, when the cross-sections of the intermediate body 321 and the main body 351 are both circular, if the diameter of the intermediate body 321 is smaller than that of the main body 351, then the first limiting portion 356 can also prevent the intermediate portion 32 from coming out in the direction of the main body 351. Similarly, when the cross-sections of the intermediate body 321 and the fixing portion 36 are both circular, if the diameter of the intermediate body 321 is smaller than that of the fixing portion 36, then the second limiting portion 323 can also prevent the intermediate portion 32 from coming out in the direction of the fixing portion 36.

[0055] Furthermore, if Figure 4As shown, a protruding portion 361 protrudes from the fixing portion 36. A sliding groove 362 is recessed on one side of the lens body portion 2 close to the middle portion 32. The self-locking rotating portion 35 is configured to drive the fixing portion 36 to rotate in the first direction A when rotating in the first direction A, so that when the fixing portion 36 is detachably connected to the lens body portion 2, the protruding portion 361 slides out of the sliding groove 362, thereby realizing the separation of the adapter assembly 3 from the lens body portion 2. In other embodiments, a protruding portion 361 protrudes from the fixing portion 36, and a sliding groove (not shown in the figure) is recessed on one side of the handle portion 1 close to the middle portion 32. The self-locking rotating portion 35 is configured to drive the fixing portion 36 to rotate in the first direction A when rotating in the first direction A, so that when the fixing portion 36 is detachably connected to the handle portion 1, the protruding portion 361 slides out of the sliding groove, thereby realizing the separation of the adapter assembly 3 from the handle portion 1. It can be understood that the protruding portion 361 can be in the shape of a wedge or a cylinder, etc.; the number of the protruding portions 361 on the fixing portion 36 can be 2 and are symmetrically arranged; the number of the sliding grooves 362 on the lens body base 2 can be 2 and are symmetrically arranged. Of course, in this embodiment, the number and arrangement manner of the protruding portion 361 and the sliding groove 362 are not limited and can be reasonably set according to actual needs.

[0056] Further, as Figure 4 shown, when the fixing portion 36 is detachably connected to the lens body portion 2, a first thread 325 is provided on the intermediate body 321, and a second thread 326 adapted to the first thread 325 is provided on one side of the handle portion 1 close to the middle portion 32, thereby realizing the detachable connection of the adapter assembly 3 and the handle portion 1. It can be understood that the first thread 325 can be provided on the inner or outer side of the intermediate body 321. Correspondingly, the second thread 326 can be provided on the outer or inner side of the handle portion 1.

[0057] When the fixing portion 36 is detachably connected to the handle portion 1, a first thread 325 is provided on the intermediate body 321, and a second thread 326 adapted to the first thread 325 is provided on one side of the lens body portion 2 close to the middle portion 32, thereby realizing the detachable connection of the adapter assembly 3 and the lens body portion 2. It can be understood that the first thread 325 can be provided on the inner or outer side of the intermediate body 321. Correspondingly, the second thread 326 can be provided on the outer or inner side of the lens body portion 2.

[0058] As Figure 5 、 Figure 6As shown, when the self-locking rotating part 35 rotates in the first direction A, the second end 354 of the elastic part 352 abuts against the blocking body 322 and elastically contracts, driving the fixing part 36 to rotate in the first direction A so that the fixing part 36 is in the installation position. When the fixing part 36 is detachably connected to the lens body part 2, the fixing part 36 is separated from the lens body part 2, or when the fixing part 36 is detachably connected to the handle part 1, the fixing part 36 is separated from the handle part 1. As Figure 7 shown, when the acting force on the self-locking rotating part 35 disappears, the elastic part 352 elastically returns, causing the self-locking rotating part 35 to rotate in the second direction B opposite to the first direction A, and driving the fixing part 36 to rotate in the second direction B. When the fixing part 36 is detachably connected to the lens body part 2, the fixing part 36 is fixed to the lens body part 2, or when the fixing part 36 is detachably connected to the handle part 1, the fixing part 36 is fixed to the handle part 1. It can be understood that the installation position can be the state of the fixing part 36 when the convex part 361 does not slide into the chute 362.

[0059] The detachable electronic endoscope 100 provided in this embodiment can replace different lens body parts 2 in different scenarios, that is, different lenses can be replaced, thereby improving the flexibility of the electronic endoscope 100 and reducing the replacement cost of the electronic endoscope 100.

[0060] In one embodiment, as Figure 8 shown, the lens body part 2 may further include a lens body seat 21 for detachably connecting to the rotating part 31. A guiding part 22 protrudes from the lens body seat 21. A receiving groove 11 is recessed in the handle part 1 at a position corresponding to the guiding part 22. The guiding part 22 is used to guide the lens body part 2 to be fixed to the handle part 1 in a predetermined direction when it is received in the receiving groove 11. As Figure 8 shown, the guiding part 22 may also be two cylindrical structures arranged oppositely. As Figure 9 shown, the guiding part 22 may also be two square column structures arranged oppositely. As Figure 10 shown, the guiding part 22 may be a regular circular, square or elliptical convex platform structure combined with various shapes, or an irregular circular, square or elliptical convex platform structure combined with various shapes. Through the guiding effect of the guiding part 22 and the receiving groove 11, the fiber optic interface (not shown in the figure) and the electrical interface (not shown in the figure) can be plugged in the correct direction, which can not only prevent joint damage caused by misinstallation without direction, but also improve the installation efficiency of the lens body part 2 and the handle part 1.

[0061] When it is necessary to install and fix the lens body part 2 and the handle part 1, the self-locking rotating part 35 can be rotated in the first direction A first, and it can be rotated until the maximum limit of the elastic part 352. Then, the guiding part 22 of the lens body part 2 is aligned with the receiving groove 11, so that the guiding part 22 is accommodated in the receiving groove 11. At this time, if the self-locking rotating part 35 is released, the self-locking rotating part 35 rotates in the second direction B under the elastic restoring action of the elastic part 352, so that the convex part 361 is caught in the sliding groove 362, thereby realizing the fixed connection between the adapter assembly 3 and the lens body part 2.

[0062] The above are only alternative embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
