In other embodiments, there are multiple power mechanisms, each power mechanism 22 has one operating arm 23, and multiple operating arms extend into the body from one notch, and at this time, multiple power mechanisms 22 may be disposed on one robot arm 21 or on multiple robot arms 21. It should be noted that a plurality of manipulation arms 23 may also extend into the body from a plurality of incisions, e.g., two manipulation arms in each incision, and e.g., one manipulation arm in each incision.
In an embodiment, the slave operation device 2 further includes a poking card, the poking card is used for penetrating through an incision on a human body and is fixedly arranged in an incision area, and the operation arm extends into the human body through the poking card.
As shown in fig. 4 to 9, which are schematic structural diagrams of different embodiments of the slave operation device.
The slave manipulator 2 further comprises a connecting mechanism 10 for connecting the manipulator arm 23 to the power mechanism 22, so that the power mechanism 22 drives the manipulator arm 23 to operate. Specifically, the slave operation device includes: a connecting mechanism 10, a power mechanism 22 and an operating arm 23. The connecting mechanism 10 is provided with a connecting groove 110, and the side wall of the connecting groove 110 is provided with a clamping groove 120 for connecting with the power mechanism 22 and the operating arm 23; the power mechanism 22 has a clamping portion 140 and a clamping unit 150 disposed on the clamping portion 140, the clamping portion 140 is accommodated in the connecting groove 110, and the clamping unit 150 is clamped with the clamping groove 120, so that the power mechanism 22 is connected with the connecting mechanism 10; the operation arm 23 has a clamping portion 140 and a clamping unit 150 disposed on the clamping portion 140, the clamping portion 140 is accommodated in the connecting groove 110, and the clamping unit 150 is clamped with the clamping groove 120, so that the operation arm 23 is connected with the connecting mechanism 10.
In other embodiments, only the actuating mechanism 22 or the operating arm 23 may be connected to the connecting mechanism 10 through the slot 120 in the connecting slot 110, and the connecting slot 110 and the slot 120 corresponding to the actuating mechanism may be correspondingly disposed.
In the slave operation device, the power mechanism 22 is connected with the operation arm 23 and is connected with the connecting mechanism 10 through the clamping portion 140 and the clamping unit 150, so that the power mechanism 22 is connected with the operation arm 23, and the power mechanism 22 drives the operation arm 23 to operate. Because the clamping portion 140 is accommodated in the connecting groove 110, the clamping unit 150 is clamped with the clamping groove 120, so that the connection is firmer and more stable, the driving effect is better, and the operation of the operating arm 23 is better and more accurate. Further, the slave operation device having the above-described structure can be connected quickly, reducing the time taken to connect the operation arm 23 or replace the operation arm 23.
As shown in fig. 4 and 5, in the present embodiment, the connecting slot 110 is located in the middle region of the connecting mechanism 10. For example, the connecting slot 110 is one, and the center thereof coincides with the center of the connecting mechanism 10. For another example, the connecting slots 110 are plural, are located in the middle of the connecting mechanism 10, and are symmetrically distributed around the center of the connecting mechanism 10. In other embodiments, the connecting slot 110 may be located in other areas, for example, the connecting slot 110 is plural and distributed along the circumference of the connecting mechanism 10. Note that, when the connecting groove 110 is plural, the clamping portion 140 is provided corresponding to the clamping unit 150. That is, each connecting groove 110 is connected with at least one clamping portion 140.
As shown in fig. 6, in an embodiment, the clamping unit 150 of the power mechanism 22 and the clamping unit 150 of the operating arm 23 are clamped in the same clamping slot 120. For example, the connection slot 110 is a through slot, and the power mechanism 22 and the connection arm respectively extend into the connection slot 110 from two sides of the through slot and are both clamped with the clamping slot 120 in the connection slot 110. In other embodiments, the clamping unit 150 of the power mechanism 22 is clamped with the clamping unit 150 of the operating arm 23, and may also be clamped in different clamping slots 120, in this case, different clamping slots 120 may be either clamping slots 120 in one connecting slot 110 or clamping slots 120 in different connecting slots 110. For example, as shown in fig. 7, only the clamping portion 140 of the actuating mechanism 22 or the operating arm 23 is received in the connecting groove 110, and the clamping groove 120 thereon is clamped with the corresponding clamping unit 150. As shown in fig. 8, the connection groove 110 accommodates therein the clamping portions 140 of the actuating mechanism 22 and the operating arm 23, and at this time, the connection groove 110 has a plurality of clamping slots 120 therein, and each clamping slot 120 is clamped with the clamping unit 150 of the actuating mechanism 22 or the operating arm 23, wherein the plurality of clamping slots 120 may be distributed along the periphery of the connection groove 110, and the plurality of clamping slots 120 may be arranged in one or more rows along the extending direction of the connection groove 110.
In one embodiment, the clamping unit 150 is movable relative to the clamping portion 140 to clamp or separate the clamping unit 150 from the clamping slot 120. For example, the card unit 150 is rotatably disposed on the card portion 140 so that the card unit 150 can be engaged with or disengaged from the card slot 120. Specifically, when the clamping portion 140 extends into the connecting groove 110, the free end of the clamping unit 150 is disposed adjacent to the clamping portion 140 to extend into the connecting groove 110 together with the clamping portion 140, and then the clamping unit 150 is rotated to be clamped with the clamping groove 120; when the clamping slot 120 is released, the clamping unit 150 is rotated to make the free end of the clamping unit 150 adjacent to the clamping portion 140, so that the clamping unit 150 is separated from the clamping slot 120. Wherein, the free end of the clamping unit 150 refers to the end not connected with the clamping part 140. For another example, the clamping unit 150 is telescopically disposed on the clamping portion 140, so that the clamping unit 150 is clamped or separated from the clamping slot 120, and when clamping is performed, the clamping unit 150 extends out, and when separating, the clamping unit 150 retracts.
Specifically, the clamping unit 150 can be connected to a motor to control the relative movement of the clamping unit 150 with respect to the clamping portion 140, so that the clamping unit 150 can be clamped to or separated from the clamping slot 120. Alternatively, the latch unit 150 may be connected to an elastic mechanism, for example, when the latch unit 150 is in a latched state (as shown in fig. 6 to 8), that is, when the free end of the latch unit 150 moves to a position far away from the latch portion 140, the latch unit 150 is latched to the latch slot 120 by the elastic force of the elastic mechanism, at this time, the power portion or the operating arm 23 has a release mechanism for separating the latch unit 150 from the latch slot 120, for example, the release mechanism is a switch for placing the latch unit 150 in a housed state, that is, the latch unit 150 moves to a position near the latch portion 140 (as shown in fig. 5), so as to extend into the connecting slot 110.
Further, the clamping portion 140 is provided with an accommodating groove 160 for accommodating the clamping unit 150, and when the clamping portion 140 needs to extend into the connecting groove 110 or be taken out from the connecting groove 110, the clamping unit 150 is accommodated in the accommodating groove 160. In one embodiment, the latch unit 150 is completely received in the receiving slot 160, so that the operation arm 23 and the power mechanism 22 are connected to the connection unit more stably. In other embodiments, the clamping unit 150 can be partially received in the receiving slot 160.
In one embodiment, the clamping portion 140 is provided with a plurality of clamping units 150, and the plurality of clamping units 150 are distributed along the periphery of the clamping portion 140. In this way, the connection stability is further improved. For example, four snap units 150 are symmetrically arranged along the circumference of the snap part 140.
In an embodiment, as shown in fig. 9, the extending direction of the clamping unit 150 and the clamping portion 140 forms an acute angle, it can also be understood that the clamping unit 150 and the clamping portion 140 form an umbrella shape, and at this time, the clamping groove 120 is disposed corresponding to the clamping unit 150.
In one embodiment, as shown in fig. 10, the clamping unit 150 has a blade shape, and the surface thereof abuts against the sidewall of the clamping groove 120. The thicknesses of the blade-shaped engaging units 150 may be the same or different. For example, the thickness of the region where the card-contacting unit 150 contacts the card slot 120 is gradually increased in a direction away from the bottom surface of the card slot 120.
As shown in fig. 5, in an embodiment, a limiting unit 170 is disposed on an inner wall of the slot 120 to enable the clamping unit 150 to move along a limited path, specifically, the limiting unit protrudes relative to a sidewall of the slot 120, and a limiting groove (not shown) is disposed on the clamping unit 150 for sleeving the limiting unit to move along the limited path of the limiting unit. When the clamping unit 150 is rotatably disposed on the clamping portion 140, the path is an arc path, and when the clamping unit 150 is telescopically disposed on the clamping portion 140, the path is a straight path. In other embodiments, a stopper unit may be provided in the storage groove 160.
In the embodiment shown in fig. 10 and 11, the slave operation device includes: a connecting mechanism 10, a power mechanism 22 and an operating arm 23. Specifically, the connecting mechanism 10 has a clamping portion 140 and a clamping unit 150 disposed on the clamping portion 140, wherein the two clamping portions 140 are disposed on two surfaces of the connecting mechanism 10 connected to the power mechanism 22 and the operating arm 23, respectively; the power mechanism 22 is provided with a connecting groove 110, the side wall of the connecting groove 110 is provided with a clamping groove 120, the clamping portion 140 corresponding to the connecting groove is accommodated in the connecting groove 110, and the clamping unit 150 is clamped with the clamping groove 120; the operation arm 23 is provided with a connecting groove 110, a clamping groove 120 is provided on a side wall of the connecting groove 110, the corresponding clamping portion 140 is accommodated in the connecting groove 110, and the clamping unit 150 is clamped with the clamping groove 120.
In other embodiments, only the actuating mechanism 22 or the operating arm 23 may be connected to the connecting mechanism 10 through the slot 120 in the connecting slot 110, and the clamping portion 140 and the clamping unit 150 may be disposed accordingly.
