[0058] The above-mentioned drawings have shown clear embodiments of the present application, which will be described in more detail later.

DETAILED DESCRIPTION

[0059] In related technology, surgical robots include an instrument transmission box and a slave manipulator arm. The instrument transmission box includes a transmission shaft and a drive cable. The transmission shaft, through the tensioned drive cable, drives the actuator of the manipulator arm to move, thereby performing surgical operations. Multiple drive cables are provided, each with a first end connected to the transmission shaft. The second end of each drive cable passes over a roller and then passes through a connecting rod. The second end of the drive cable, which exits the connecting rod, is connected to the manipulator arm.

[0060] During the assembly of a surgical robot, the first end of a drive cord must be wrapped around a transmission shaft and pre-tensioned to maintain a taut state, thereby ensuring the stability of the drive cord. However, when the pre-tension is applied to the drive cord by manually tightening it, the drive cord can easily become loose after the user releases the tension, resulting in poor transmission stability between the drive cord and the transmission shaft.

[0061] In order to solve the above-mentioned problems, the present application provides a drive rope tensioning tool, comprising a base, an adjusting member, and a locking member. The base is at least used to fix the box body of the instrument transmission box; the adjusting member is rotatable about a first direction and is arranged on the base; the output end of the adjusting member is at least used to connect to the transmission shaft of the instrument transmission box, and the output end of the adjusting member is at least used to drive the transmission shaft to rotate in the first direction relative to the box body in the forward direction; the locking member is arranged on the base; when the adjusting member is in the locked state, the locking member is at least used to limit the reverse rotation of the transmission shaft relative to the box body. When the adjusting member rotates in the forward direction, it can drive the end of the drive rope of the instrument transmission box close to the transmission shaft to be wound around the transmission shaft, so that the adjusting member provides pre-tension to the drive rope, so that the drive rope is in a tensioned state; the locking member arranged on the base can limit the reverse rotation of the transmission shaft, so that the drive rope is not easily loosened.

[0062] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0063] See also Figures 1-6 The present application provides a drive rope tensioning tool, including a base 100. The base 100 can be used to support other components of the drive rope tensioning tool. The base 100 can also be used to fix the box body 410 of the instrument transmission box 400.

[0064] See also Figures 1-6 In some embodiments of the present application, the drive rope tensioning tool further includes an adjusting member 200. The adjusting member 200 is rotatable about a first direction and is disposed on the base 100, that is, the adjusting member 200 can rotate on the base 100. The adjusting member 200 can be a rotating body structure, and the first direction is parallel to the axis direction of the adjusting member 200.

[0065] In some embodiments of the present application, the output end of the adjusting member 200 is at least used to connect to the transmission shaft 420 of the instrument transmission box 400, and the output end of the adjusting member 200 is at least used to drive the transmission shaft 420 to rotate forward relative to the box body 410 around the first direction.

[0066] Specifically, the output end of the adjusting member 200 is close to the instrument transmission box 400. The output end of the adjusting member 200 can be detachably connected to the transmission shaft 420 of the instrument transmission box 400. After the output end of the adjusting member 200 is connected to the transmission shaft 420 of the instrument transmission box 400, the adjusting member 200 can rotate synchronously with the transmission shaft 420.

[0067] See also Figure 2 、 Figure 8 and Figure 14 In some embodiments of the present application, the drive rope tensioning tool further includes a locking member 300. The locking member 300 is disposed on the base 100. The locking member 300 can be used to limit the reverse rotation of the adjusting member 200.

[0068] When the adjusting member 200 is in the locked state, the locking member 300 is at least used to limit the transmission shaft 420 from rotating in the opposite direction relative to the box body 410. The locking member 300 can limit the adjusting member 200 and the transmission shaft 420 from rotating in the direction close to the locking member 300 by abutting against the adjusting member 200.

[0069] When the adjusting member 200 rotates forward, it can drive the driving rope 440 of the instrument transmission box 400 to be wrapped around the transmission shaft 420 at one end thereof, so that the adjusting member 200 provides pre-tension to the driving rope 440 to make the driving rope 440 in a tensioned state; the locking member 300 arranged on the base 100 can limit the reverse rotation of the driving shaft 420, so that the driving rope 440 is not easily loosened.

[0070] It should be noted that multiple transmission shafts 420, multiple drive ropes 440 and multiple rollers are arranged at intervals on the instrument transmission box 400. The multiple transmission shafts 420 correspond to the multiple drive ropes 440 one-to-one, and the multiple drive ropes 440 correspond to the multiple rollers one-to-one.

[0071] The first end of each drive rope is connected to the corresponding transmission shaft. The second end of the drive rope passes over the corresponding roller and then passes through the connecting rod 430. The second end of the drive rope that passes through the connecting rod 430 is connected to the manipulator. The rollers can be arranged in a staggered manner to space the multiple drive ropes passing through the connecting rod 430 to prevent them from becoming entangled and affecting their movement.

[0072] See also Figure 8 and Figure 14 In some embodiments of the present application, the locking member 300 is fixedly connected to the base 100. The locking member 300 can be in a cylindrical or strip-shaped form. Specifically, the locking member 300 can be fixedly connected to the base 100 by welding, bonding, or interference fit to improve the stability of the connection between the locking member 300 and the base 100.

[0073] See also Figure 8 In some embodiments of the present application, the adjusting member 200 is provided with an abutting surface 211. The abutting surface 211 may be a plane. The abutting surface 211 may be used to abut against the locking member 300.

[0074] In some embodiments of the present application, when the adjusting member 200 is in the locked state, the adjusting member 200 abuts against the locking member 300 via the abutting surface 211. That is, after the adjusting member 200 abuts against the locking member 300 via the abutting surface 211, the adjusting member 200 cannot rotate in the opposite direction, and the transmission shaft 420 connected to the adjusting member 200 cannot rotate in the opposite direction relative to the box body 410.

[0075] The adjusting member 200 is provided with an abutting surface 211, so that when the adjusting member 200 is in a locked state, the abutting surface 211 of the adjusting member 200 abuts against the locking member 300, so that the locking member 300 limits the adjusting member 200 and the transmission shaft 420 of the instrument transmission box 400 from rotating in the opposite direction, so that the driving rope 440 of the instrument transmission box 400 is not easy to loosen.

[0076] See also Figure 7-Figure 9In some embodiments of the present application, the adjusting member 200 can be movably disposed on the base 100 along a first direction. Specifically, the adjusting member 200 can be slidably disposed on the base 100 along the first direction. When the adjusting member 200 slides on the base 100, the adjusting member 200 can be in a first position, a second position, or other positions.

[0077] When the adjusting member 200 is in the first position, the contact surface 211 is at least used to contact the locking member 300. At this time, the distance between the adjusting member 200 and the instrument transmission box 400 is minimum. When the adjusting member 200 is in the second position, the contact surface 211 does not contact the locking member 300.

[0078] When the adjusting member 200 is in the locked state, the adjusting member 200 is located at the first position. When the adjusting member 200 is in the first position, the locking member 300 abuts against the adjusting member 200, and the locking member 300 can restrict the adjusting member 200 and the transmission shaft 420 from rotating in the opposite direction.

[0079] When the adjusting member 200 is in the rotating state, the adjusting member 200 rotates forwardly around the first direction, and the adjusting member 200 moves between the first position and the second position along the first direction.

[0080] See also Figure 7-Figure 9 In some embodiments of the present application, the adjusting member 200 is provided with an elastic member 500. For example, the elastic member 500 can be a cylindrical coil spring or a variable diameter coil spring.

[0081] See also Figure 7-Figure 9 and Figure 13-14 In some embodiments of the present application, a first end of the elastic member 500 is connected to the base 100, and a second end of the elastic member 500 is connected to the adjusting member 200. The first end of the elastic member 500 may be an end close to the vertical portion of the base 100, and the second end of the elastic member 500 may be an end away from the vertical portion of the base 100. Specifically, the first end of the elastic member 500 is fixedly connected to the base 100, and the second end of the elastic member 500 is fixedly connected to the adjusting member 200.

[0082] In some embodiments of the present application, the first end of the elastic member 500 can be fixed to the base 100 by welding or screw connection, so as to improve the connection stability between the elastic member 500 and the base 100.

[0083] In some embodiments of the present application, the second end of the elastic member 500 can be fixed to the adjusting member 200 by welding or screw connection, so as to improve the connection stability between the elastic member 500 and the adjusting member 200.

[0084] The second end of the elastic member 500 is extendable and retractable along the first direction. The elastic member 500 is at least configured to drive the adjusting member 200 into contact with the locking member 300 via the abutment surface 211. The second end of the elastic member 500 is movable along the first direction away from the instrument transmission box 400 to drive the adjusting member 200 away from the instrument transmission box 400. The second end of the elastic member 500 is movable along the first direction toward the instrument transmission box 400 to drive the adjusting member 200 toward the instrument transmission box 400, thereby facilitating abutment between the abutment surface 211 and the locking member 300.

[0085] See also Figure 8 In some embodiments of the present application, the adjusting member 200 is provided with a contact portion, which forms a push surface 212 and an abutting surface 211 that are connected. The abutting surface 211 can be a flat surface arranged parallel to the first direction. The pushing surface 212 can be an inclined surface. The pushing surface 212 and the abutting surface 211 form an angle, so that when the pushing surface 212 contacts the locking member 300, the locking member 300 drives the adjusting member 200 toward or away from the instrument transmission box 400 via the pushing surface 212.

[0086] When the adjusting member 200 is in the rotating state, the adjusting member 200 rotates forwardly about the first direction, the locking member 300 is used to abut against the pushing surface 212, and the adjusting member 200 moves from the first position to the second position. Specifically, when the locking member 300 abuts against the first end of the pushing surface 212, the adjusting member 200 is in the first position, and the distance between the adjusting member 200 and the instrument transmission box 400 is minimized; when the locking member 300 abuts against the second end of the pushing surface 212, the adjusting member 200 is in the second position.

[0087] See also Figure 8-Figure 9 In some embodiments of the present application, the number of contact portions is set to multiple, and the multiple contact portions are arranged in sequence. The multiple contact portions can be evenly distributed around the circumference of the adjustment member 200, and the gaps between adjacent contact portions are equal to improve the balance of the adjustment member 200.

[0088] In some embodiments of the present application, a transition portion is provided between adjacent contact portions. When the transition portion is positioned relative to the locking member 300, the adjusting member 200 can be positioned in the first position. Specifically, the transition portion is provided with a transition surface 213. If the transition surface 213 is perpendicular to the rotation axis of the adjusting member 200, then when the transition surface 213 is positioned relative to the locking member 300, the distance between the adjusting member 200 and the instrument transmission box 400 remains unchanged, and the adjusting member 200 is always positioned in the first position.

[0089] In some embodiments of the present application, a transition portion is provided between adjacent contact portions. When the transition portion is disposed relative to the locking member 300, the adjusting member 200 is positioned between the first position and the second position. Specifically, the transition portion is provided with a transition surface 213. If the transition surface 213 forms an angle with the rotation axis of the adjusting member 200 and the transition surface 213 is not perpendicular to the rotation axis of the adjusting member 200, then when the transition surface 213 is disposed relative to the locking member 300, the distance between the adjusting member 200 and the instrument transmission box 400 will change, and the adjusting member 200 will be positioned between the first position and the second position.

[0090] See also Figure 7-Figure 9 and Figure 13-14 In some embodiments of the present application, the adjusting member 200 includes a driving portion 210, an extending portion 220, and a fixing portion 230 sequentially arranged along a first direction. The extending portion 220 is connected to the driving portion 210, and the fixing portion 230 is connected to an end of the extending portion 220 away from the driving portion 210.

[0091] Specifically, the extension portion 220 can be fixedly connected to the driving portion 210. For example, the extension portion 220 can be fixedly connected to the driving portion 210 by welding, screw connection, or interference fit. The fixing portion 230 can be fixedly connected to the extension portion 220. For example, the fixing portion 230 can be fixedly connected to the extension portion 220 by welding, screw connection, or interference fit.

[0092] See also Figure 8 In some embodiments of the present application, when the adjusting member 200 is in the locked state, the driving portion 210 abuts against the locking member 300. Specifically, when the adjusting member 200 is in the locked state, the abutting surface 211 of the driving portion 210 abuts against the locking member 300.

[0093] See also Figure 13-14 In some embodiments of the present application, the extension portion 220 is disposed through the base 100. Specifically, the base 100 may be provided with a through hole, and the extension portion 220 is disposed through the through hole of the base 100. The extension portion 220 can rotate relative to the base 100 about a first direction, that is, the extension portion 220 can rotate about the through hole of the base 100, so that the adjustment member 200 provides a pre-tension to the drive rope 440, thereby tensioning the drive rope 440.

[0094] In some embodiments of the present application, the fixing portion 230 is at least used to fix to the transmission shaft 420. After the fixing portion 230 is fixed to the transmission shaft 420, the adjusting member 200 can rotate synchronously with the transmission shaft 420. The fixing portion 230 forms the output end of the adjusting member 200, so as to facilitate connection with the transmission shaft 420 of the instrument transmission box 400.

[0095] See also Figure 6-Figure 7 、 Figure 10 and Figure 13In some embodiments of the present application, the fixing portion 230 is provided with a receiving groove 231. The receiving groove 231 faces the instrument transmission box 400. The shape of the receiving groove 231 matches the end of the transmission shaft 420 facing the fixing portion 230.

[0096] The receiving groove 231 is used to accommodate at least the transmission shaft 420. The end of the transmission shaft 420 facing the fixed portion 230 can be inserted into the receiving groove 231, allowing the transmission shaft 420 to rotate synchronously with the adjusting member 200. The cross-sectional shape of the receiving groove 231 can be a cross or T-shaped, etc., to prevent the transmission shaft 420 and the adjusting member 200 from rotating relative to each other.

[0097] When the adjusting member 200 is in the first position, the fixing portion 230 secures the transmission shaft 420 via the receiving slot 231. The transmission shaft 420 can slide axially along the receiving slot 231, facilitating movement of the adjusting member 200 between the first and second positions. The transmission shaft 420 and the receiving slot 231 are prevented from rotating relative to each other, allowing the transmission shaft 420 to rotate synchronously with the adjusting member 200.

[0098] When the adjusting member 200 is located at the third position, the fixing portion 230 is disengaged from the transmission shaft 420. When the fixing portion 230 is disengaged from the transmission shaft 420, the instrument transmission box 400 can be removed from the drive rope tensioning tool.

[0099] See also Figure 13-14 In some embodiments of the present application, the base 100 includes a main body 110 and a support structure 120 connected to each other. The main body 110 and the support structure 120 are fixedly connected. Specifically, the main body 110 and the support structure 120 can be fixed by welding or bolting to improve the connection stability between the main body 110 and the support structure 120.

[0100] The driving portion 210 and the fixing portion 230 are located on both sides of the support structure 120. When one of the driving portion 210 and the fixing portion 230 is close to the support structure 120, the other of the driving portion 210 and the fixing portion 230 is away from the support structure 120.

[0101] See also Figure 12-14 In some embodiments of the present application, the first surface of the main body 110 is at least used to fix the box body 410. The first surface of the main body 110 is the end surface facing the adjustment member 200. The first surface of the main body 110 can be provided with a slot 111, which can penetrate the first surface of the main body 110. The box body 410 can be fixed to the main body 110 via the slot 111. The slot 111 is used to position and fix the instrument transmission box 400 so that the box body 410 can remain stable when the adjustment member 200 provides pre-tension to the drive rope 440.

[0102] It should be noted that, when installing the instrument transmission box 400 , the instrument transmission box 400 may be manually pressed downward into the slot 111 to position and fix the instrument transmission box 400 .

[0103] In some embodiments of the present application, a first end of the support structure 120 is disposed on the main body 110, and a second end of the support structure 120 extends away from the second surface of the main body 110. The first end of the support structure 120 is close to the main body 110, and the second end of the support structure 120 is away from the main body 110. The second surface of the main body 110 is the end surface facing away from the adjustment member 200.

[0104] Specifically, the first end of the support structure 120 may be fixedly connected to the main body 110. For example, the first end of the support structure 120 may be fixedly connected to the main body 110 by welding or screw connection.

[0105] In some embodiments of the present application, the support structure 120 is connected to the adjustment member 200 and the locking member 300. The support structure 120 can be fixedly connected to the locking member 300. For example, the support structure 120 can be fixedly connected to the locking member 300 by welding, bonding, or interference fit to improve the connection stability between the locking member 300 and the support structure 120.

[0106] The extension portion 220 of the adjustment member 200 is disposed through the support structure 120 of the base 100. Specifically, the support structure 120 may be provided with a through hole, and the extension portion 220 is disposed through the through hole of the support structure 120. The extension portion 220 is rotatable relative to the support structure 120 in a first direction, that is, the extension portion 220 is rotatable about the through hole of the support structure 120, so that the adjustment member 200 provides a pre-tension to the drive rope 440, thereby maintaining a tensioned state of the drive rope 440.

[0107] See also Figure 10-11 In some embodiments of the present application, the support structure 120 is provided with a clearance groove 121, which is used to accommodate at least the connecting rod 430 of the instrument transmission box 400. The clearance groove 121 can be a rectangular groove or a circular groove. The clearance groove 121 penetrates the support structure 120, allowing the connecting rod 430 of the instrument transmission box 400 to pass through the clearance groove 121, thereby facilitating the installation of the instrument transmission box 400 on the drive rope tensioning tool.

[0108] The process of installing the instrument transmission box 400 on the drive rope tensioning tool is as follows:

[0109] The driving portion 210 is pulled away from the support structure 120. The driving portion 210 drives the fixing portion 230 toward the support structure 120 through the extending portion 220. After the driving portion 210 reaches the limit position, the fixing portion 230 avoids the slot 111 in the extension direction of the support structure 120, and the elastic member 500 is in a compressed state.

[0110] The instrument transmission box 400 is pressed downward into the slot 111 to position and fix the instrument transmission box 400;

[0111] The driving part 210 is released so that it relies on the rebound force of the elastic member 500 to approach the support structure 120. At the same time, the driving part 210 drives the fixing part 230 away from the support structure 120 through the extension part 220, so that the fixing part 230 is connected to the transmission shaft 420 of the instrument transmission box 400.

[0112] The process of tensioning the drive rope 440 of the instrument transmission box 400 is as follows:

[0113] In the initial state, the abutting surface 211 of the adjusting member 200 abuts against the locking member 300;

[0114] When the adjusting member 200 rotates in the forward direction, please refer to Figure 2 and Figure 8 , which can drive the end of the driving rope 440 of the instrument transmission box 400 close to the transmission shaft 420 to be wound around the transmission shaft 420, so that the adjustment member 200 provides a pre-tension to the driving rope 440, so that the driving rope 440 is in a tensioned state;

[0115] After the drive rope 440 is tightened, the adjusting member 200 stops rotating, so that the locking member 300 abuts against the abutting surface 211. The locking member 300 can limit the reverse rotation of the transmission shaft 420, so that the drive rope 440 is not easily loosened.

[0116] During the forward rotation of the adjusting member 200 , when the locking member 300 contacts the pushing surface 212 , the adjusting member 200 moves from the first position toward the second position.

[0117] During the forward rotation of the adjusting member 200 , when the locking member 300 is arranged opposite to the transition portion, the adjusting member 200 may be located at the first position or between the first position and the second position.

[0118] During the forward rotation of the adjusting member 200 , when the locking member 300 abuts against the abutting surface 211 , the locking member 300 can restrict the transmission shaft 420 from rotating in the reverse direction, so that the driving rope 440 is not easily loosened.
