Description

Sterile plate assembly, surgical instrument, power box and surgical robot system

Technical Field

The invention relates to the technical field of robot-assisted surgery, in particular to an aseptic plate assembly, a surgical instrument, a power box and a surgical robot system.

Background

In recent years, with the application and development of related technologies of robots, especially the development of computing technologies, the role of medical surgical robots in clinical practice is more and more emphasized. The minimally invasive surgery robot system can reduce the physical labor of a doctor in the surgery process in an interventional therapy mode, and meanwhile achieves the purpose of accurate surgery, so that the patient has small wound, less blood loss, less postoperative infection and quick postoperative recovery.

The minimally invasive surgical robot system enables a doctor to remotely control mechanical arms and surgical tool instruments on the slave operation robot at the master control console to complete operation of a surgery. The development of minimally invasive surgical robotic devices has not only enabled physicians to complete surgery with less invasive, but the same viewing angle and operational feel as traditional open surgery. More importantly, the medical instrument enables a doctor to carry out operation at a place far away from a patient, or to carry out operation beside the patient in a ward, or can remotely control a remote receiving device through an operation input device, so as to complete the operation of the operation.

In telesurgery, the surgeon uses some form of remote control, such as a servo, to manipulate the movement of the surgical instruments, rather than directly holding and moving the instruments. In telesurgical systems, a surgeon controls a surgical workstation by operating a master control device, which in turn controls the movement of servo-mechanical surgical instruments, to perform a surgical procedure on a patient.

However, if this type of operation is to be performed, a system/device must be provided to support and move the surgical instruments, which is typically accomplished by a robotic arm. Surgical instruments can be contacted with focuses of patients to cause pollution in the surgical process, multiple times of disinfection and sterilization are usually required to realize multiplexing, mechanical arms of a surgical robot are usually required to be repeatedly used, but the surgical instruments and the mechanical arms are required to be isolated by a sterile plate because the surgical instruments are large in size and contain a plurality of parts which are not beneficial to disinfection and sterilization, such as electronic devices, encoders or sensors, and the like, so that the surgical instruments can be subjected to acting forces in a plurality of directions according to different operation conditions in the surgical process in order to avoid further pollution of the mechanical arms by the contaminated surgical instruments in the surgical process, the surgical instruments and the mechanical arms are required to be isolated by the sterile plate, in addition, different surgical instruments are required to be repeatedly replaced in the surgical process to finish operations such as shearing, suturing or electrocoagulation, and the like, and the surgical instruments or the sterile plate can often shake to different degrees relative to the mechanical arms when the conventional surgical instruments or the sterile plate are subjected to the action of external force, and the accurate control of the surgical instruments is not beneficial, meanwhile, potential safety hazards can be caused, and on the other hand, the locking structure of the current surgical instrument or sterile plate has the risk of tripping.

Referring to fig. 1 to 3, fig. 1 is a schematic view of a surgical scene of a surgical robot system according to the present invention; FIG. 2 is a schematic view of a tool arm supporting and mounting a surgical instrument in accordance with the present invention; fig. 3 is an assembly schematic of a surgical instrument, a sterile plate assembly, and a power pack according to the present invention.

The embodiment of the present invention provides a surgical robot system, and fig. 1 shows the surgical robot system and a surgical application scenario thereof, in an exemplary embodiment, the surgical robot system is a master-slave teleoperation surgical robot, that is, the surgical robot system includes an execution end and a control end, where the control end includes a doctor console 106 and a master manipulator 107 movably disposed on the doctor console 106. With further reference to fig. 1, the execution end includes a patient-end robot 1, the patient-end robot 1 includes a column 11 and a robot arm including a support mechanism 12 and a tool arm 13, and a surgical instrument 14 (including a manipulator, an endoscope, and the like) is mounted on or connected to the tool arm 13. The main operation principle of the surgical robot system is as follows: the doctor realizes the minimally invasive surgery treatment on the patient on the sickbed 101 through the remote operation of the doctor console 106 and the main manipulator 107. The main manipulator 107, the tool arm 13 and the surgical instrument 14 form a master-slave control relationship. Specifically, the tool arm 13 and the surgical instrument 14 move according to the movement of the main operating hand 107 during the surgical operation, i.e., the main operating hand 107 is operated by the doctor's hand to move accordingly. Further, the main operating hand 107 receives the information of the acting force of the human tissue and organ on the surgical instrument and feeds the information back to the hand of the doctor, so that the doctor can feel the surgical operation more intuitively. The distal end of the tool arm 13 is used for mounting or connecting a surgical instrument 14, so that the surgical instrument 14 can perform a surgical operation, such as rotating around a stationary point in a space; the support mechanism 12 may be rotatably connected to a plurality of tool arms 13 for adjusting the spatial position of the fixed point, and in some embodiments, may further include a plurality of support structures 12, wherein the plurality of support structures 12 are rotatably connected to the plurality of tool arms 13, respectively; the upright 11 is connected to the support means 12 for determining the spatial position of the support means 12 and the tool arm 13. Optionally, the surgical robot system further comprises an image trolley 104 and a tool trolley 105, wherein the image trolley 104 is used for providing the display surgical operation information for an assistant operator (such as a nurse) in real time. The tool cart 105 is used to place surgical instruments 14 or other tools for intraoperative access and placement of surgical instruments 14 or other tools.

The patient-side robot 1 is a specific implementation platform of the teleoperated surgical robotic system, and referring to fig. 2 and 3, a schematic diagram of a tool arm 13 of the patient-side robot 1 supporting and mounting a surgical instrument 14 is shown. As described in the background, since the surgical instrument 14 is continuously replaced during the operation, the surgical instrument 14 is connected to the tool arm 13 via the sterile plate assembly 15 in order to avoid contamination of the tool arm 13. Further, in the example shown in fig. 2 and 3, one side of the sterile plate assembly 15 is detachably coupled to the surgical instrument 14, and the other side of the sterile plate assembly 15 is detachably coupled to the power pack 16. The power cartridge 16 is used to power the surgical device 14 to drive the distal end of the surgical device 14 to perform a surgical procedure, such as a clamp, cut, scissors, etc. Of course, in other embodiments, the surgical instrument 14 may be a component such as an endoscope that does not require power input, and the power box 16 may not be provided, and the surgical instrument 14 may be connected to the tool arm 13 only through the sterile plate assembly 15. It is to be understood that the surgical robotic system shown in fig. 1 is only one example of a surgical robotic system and is not a limitation of a surgical robotic system, such as a surgical robotic system including a non-master-slave teleoperated surgical robot; the same exemplary embodiment shown in fig. 2 is only a partial example of the patient-side robot 1 and is not limited to the patient-side robot 1, and a person skilled in the art may modify and configure the specific structure of the patient-side robot 1 according to the prior art, and the present invention is not limited to this.

The first locking device 151 comprises a first pressing portion 152 and a first holding portion 153 connected with each other, and when the first locking device 151 is in the first locking position, the first holding portion 153 is used for locking a corresponding component (such as a second locking stage 161 of the power box 16, as described in detail below with respect to the power box 16) of the power box 16 (i.e. a first target object); when the first locking device 151 is in the first unlocking position, the first catch 153 is used for unlocking the corresponding component of the power cartridge 16; the first pressing part 152 is configured to be limited by the surgical instrument 14 from moving in the first direction after the sterile plate assembly 15 is used for being assembled and connected with the surgical instrument 14 (i.e., a second target object), so that the first locking device 151 is limited to be in the first locking position. Therefore, after the surgical instrument 14, the sterile plate assembly 15 and the power box 16 are assembled and connected, the first pressing part 152 of the sterile plate assembly 15 is limited by the surgical instrument 14, so that the first locking device 151 is located at the first locking position, the first clamping part 153 and the power box 16 are reliably locked, the risk that the sterile plate assembly 15 is accidentally unlocked from the power box 16 due to misoperation in an operation can be avoided, the connection reliability is improved, and the safety and the reliability of the operation are ensured.

Referring to fig. 11 to 14, in order to achieve the assembling connection with the sterile plate assembly 15, the surgical instrument 14 provided in this embodiment includes: a second substrate 140 and a second locking device 141 disposed on the second substrate 140; the second base plate 140 is used for abutting connection with the first base plate 150 of the sterile plate assembly 15; the second locking device 141 is used for locking with a corresponding component of the aseptic plate assembly 15 (such as the first locking stage 155 of the aseptic plate assembly 15, described in detail below with respect to the aseptic plate assembly 15); the second base plate 140 has a first locking channel 142, and the first locking channel 142 is configured to receive the first pressing portion 152 of the sterile plate assembly 15 and limit the movement of the first pressing portion 152 along the first direction, so that the first locking device 151 is limited to be in the first locking position.

Further, referring to fig. 19 and 20, the power box 16 of the present embodiment is provided for assembling and connecting with the aseptic board assembly 15; the power cartridge 16 includes: a third substrate 160; the third base plate 160 is for abutting connection with the first base plate 150 of the aseptic plate assembly 15; the third base plate 160 has a second locking stage 161, and the second locking stage 161 is used for being locked with the first catch 153 of the first locking device 151 of the sterile plate assembly 15, so as to lock the sterile plate assembly 15 and the power box 16.

With such a configuration, during assembly, the first pressing portion 152 passes through the second substrate 140 via the first locking channel 142. Alternatively, the first locking channel 142 can restrict the first locking device 151 at the first locking position by abutting against at least a position restricting the first pressing part 152 in the first direction toward the first unlocking position direction. In a specific exemplary embodiment, the first pressing portion 152 can be limited, for example, by a sidewall 1421 of the first locking channel 142. Preferably, the inner contour of the first locking channel 142 is adapted to the outer contour shape of the first pressing portion 152, and the first locking channel 142 can not only limit the position of the first pressing portion 152 along the first direction by abutting against, but also limit the displacement of the first pressing portion 152 in other directions in the extending direction of the second substrate 140, that is, the first pressing portion 152 can only penetrate and exit along the axial direction of the first locking channel 142, and has no other degree of freedom. With such a configuration, when the surgical instrument 14 is assembled and connected with the sterile plate assembly 15, the first pressing portion 152 and the first locking channel 142 can also serve as a positioning column and a positioning channel for positioning the assembly and connection of the two. Of course, in some other embodiments, the height of the first pressing portion 152 protruding from the first substrate 150 is not limited to be greater than or equal to the thickness of the second substrate 140, and the protruding height of the first pressing portion 152 may also be less than the thickness of the second substrate 140, and the first locking channel 142 does not need to be opened through, and may be a blind hole matching the protruding height of the first pressing portion 152. This can be reasonably arranged by those skilled in the art according to the practice.

Optionally, in the example shown in fig. 4 and 12, the aseptic plate assembly 15 includes at least two first locking devices 151, at least two first locking devices 151 being oppositely disposed; the surgical instrument 14 includes two second locking devices 141 arranged oppositely. Of course, in other embodiments, the sterile plate assembly 15 may include a greater number of first locking devices 151 and the surgical instrument 14 may include a greater number of second locking devices 141. The relative arrangement here, for two first locking means 151, can be arranged back-to-back symmetrically about an axis perpendicular to the first base plate 150, as shown in fig. 4. But in other embodiments, not limited to a symmetrical arrangement, both may be distributed at an angle about the axis perpendicular to the first substrate 150; for the plurality of first locking devices 151, the plurality of first locking devices 151 may be arranged around the axis perpendicular to the first base plate 150, and the first locking devices 151 may be arranged at a certain angle therebetween, which is not limited in the present invention. Similarly, the two second locking devices 141 are oppositely disposed, which can refer to the above description of the first locking device 151, which can mean that the two second locking devices 141 are symmetrically disposed back to back about an axis perpendicular to the second substrate 140, as shown in fig. 14.

Correspondingly, the number of first locking stages 155 of the sterile plate assembly 15 may be adapted to the number of second locking devices 141 of the surgical instrument 14 or greater than the number of second locking devices 141; the number of the second locking stages 161 of the third base plate 160 may be matched to the number of the first locking devices 151 of the aseptic plate assembly 15 or greater than the number of the first locking devices 151. It is to be understood that when the sterile plate assembly 15 comprises more than two first locking devices 151, each first locking device 151 has its own first direction, and the first directions of each first locking device 151 may be parallel to each other or may be angled to each other. Preferably, the first direction of each first locking device 151 is parallel to the extending direction of the first base plate 150.

Referring to fig. 6 and 7, optionally, the sterile plate assembly 15 further includes a first potential energy component; the first potential energy component is respectively connected with the first base plate 150 and the first locking device 151; the first potential energy component is configured to store potential energy during the process that the first locking device 151 moves from the first locking position to the first unlocking position by an external force; when the first locking device 151 is not subjected to external force or the external force is smaller than the driving force of the potential energy stored in the first potential energy component to the first locking device 151, the first potential energy component releases the potential energy to drive the first locking device 151 to move to the first locking position. Here, the case where the external force applied to the first locking device 151 is smaller than the potential energy stored in the first potential energy component to the driving force of the first locking device 151 is described, but if the external force is smaller than the driving force of the first locking device 151 by the potential energy stored in the first potential energy component, the first locking device 151 will move to the first locking position by the potential energy released by the first potential energy component.

Referring to fig. 19 and 20, the first locking device 151 can be locked with the power box 16 when in the first locking position, and in the assembly, the sterile plate assembly 15 and the surgical instrument 14 can be sequentially assembled on the power box 16, and when the sterile plate assembly 15 is assembled with the power box 16 and the surgical instrument 14 is not assembled yet, the first potential energy component is arranged to keep the first locking device 151 in the first locking position when no external force is applied, so that the assembly stability of the sterile plate assembly 15 and the power box 16 is ensured.

Optionally, the first potential energy component includes a first elastic member 154 or two first magnetic members arranged opposite to each other in the same pole. Taking the first potential energy component including the first elastic element 154 as an example, the first elastic element 154 may be a common elastic element such as a spring, a spring sheet or a plate spring, please refer to fig. 6 to 8, in an alternative embodiment, the first elastic element 154 is a spring sheet, which has a positioning region 1541 and an elastic region 1542, correspondingly, the first substrate 150 has a positioning portion 1504 for engaging and fixing the positioning region 1541, and the positioning region 1541 can be engaged and fixed on the positioning portion 1504. The shape of the elastic sheet can be V-shaped, N-shaped, W-shaped, etc., and the invention is not limited to the shape of the elastic sheet. Elastic region 1542 is connected at one end to locating region 1541 and at the other end to first locking device 151. Elastic region 1542 is capable of storing or releasing potential energy through elastic deformation. In another alternative embodiment, the first potential energy component may comprise a first magnetic element arranged opposite to each other in the same polarity, one of which is connected to the first locking device 151, and the other of which is fixed to the first substrate 150. When the first locking device 151 moves toward the first unlocking position, the two first magnetic members approach each other, generate a repulsive force, and store potential energy; when the external force applied to the first locking device 151 is removed, the two first magnetic members release potential energy due to repulsion, and the first locking device 151 is pushed to move toward the first locking position.

Referring to fig. 16 and 18, optionally, the first catch 153 has a first guiding inclined plane 156 facing the direction of the power box 16, and the first guiding inclined plane 156 gradually inclines towards the first unlocking position in the direction of the power box 16. In the example shown in fig. 16 and 18, the first direction is a horizontal direction in the drawing, the first unlocking position is a position where the two first locking devices 151 are close to the center of the first base plate 150, the first locking position is a position where the two first locking devices 151 are far from the center of the first base plate 150 toward both left and right ends, the first guide slope 156 of the first retaining portion 153 on the left side in the drawing is gradually inclined toward the center of the first base plate 150 (i.e., the right side in the drawing) toward the direction of the power cartridge 16 (i.e., the lower side in the drawing), and the first guide slope 156 of the first retaining portion 153 on the right side in the drawing is inclined toward the lower left side. It will be appreciated that the direction of the slope of the first guide ramp 156 is only related to the first locked position and the first unlocked position. When the sterile board assembly 15 is assembled with the power box 16, in some embodiments, the first locking device 151 may be driven to move to the first unlocking position by pressing the first pressing portion 152, while in other embodiments, the first locking device 151 may be pushed to move to the first unlocking position by a component force in the first direction generated by the power box 16 on the first guiding inclined surface 156 by directly utilizing the abutment of the first guiding inclined surface 156 with the power box 16. This is particularly suitable in the case where a plurality of first locking means 151 are provided, and the operator can complete the assembly by simply snap-fitting the sterile plate assembly 15 to the power pack 16 without having to perform any special operation on the first locking means 151. Note that the first guide slope 156 is not limited to a flat surface, and may be a smoothly curved surface.

Preferably, as shown in fig. 5, the first base plate 150 has a first limiting cavity 157, and the first limiting cavity 157 is used for limiting the first locking device 151 to have only a moving degree of freedom in a first direction. Referring to fig. 5, in an exemplary embodiment, the first substrate 150 may include a first substrate upper cover plate 1501 and a first substrate lower cover plate 1502, both of the first substrate upper cover plate 1501 and the first substrate lower cover plate 1502 may be assembled and spliced, the first position-limiting cavity 157 is formed between the first substrate upper cover plate 1501 and the first substrate lower cover plate 1502, the first position-limiting cavity 157 may extend along a first direction, a part of a profile shape of the corresponding first locking device 151 is matched with an inner profile of the first position-limiting cavity 157, the first locking device 151 may be engaged in the first position-limiting cavity 157 and may move along the first direction, and the first position-limiting cavity 157 limits other degrees of freedom of the first locking device 151 except for movement along the first direction. The first limiting cavity 157 can prevent the first locking device 151 from falling off, overturning or twisting from the first substrate 150, thereby improving the reliability of the movement of the first locking device 151.

Alternatively, referring to fig. 15 to 18, the first pressing portion 152 has a second guiding inclined plane 158 facing the direction of the surgical device 14, and the second guiding inclined plane 158 gradually inclines towards the first locking position in the direction of the surgical device 14. As for the inclination direction of the second guide slope 158, it can be understood with reference to the above description about the inclination direction of the first guide slope 156, and the description will not be repeated here. When the surgical instrument 14 is installed after the sterile plate assembly 15 and the power cartridge 16 are assembled, the second guiding inclined surface 158 guides the first pressing portion 152 to penetrate into the first locking channel 142, so that the first pressing portion 152 can be conveniently slid into the first locking channel 142. It should be noted that the second guiding inclined surface 158 is not limited to be a plane surface, and may be a smooth curved surface, which can also play a certain guiding role.

Alternatively, with continued reference to fig. 15 to 18, the first locking channel 142 has a fourth guiding inclined surface 143 facing the direction of the sterile plate assembly 15, and the fourth guiding inclined surface 143 is gradually inclined toward the first unlocking position in the direction of the sterile plate assembly 15. Also, as for the inclination direction of the fourth guide slope 143, it can be understood with reference to the above description about the inclination direction of the first guide slope 156, and the description will not be repeated here. The fourth guiding inclined surface 143 can also guide the first pressing portion 152 to penetrate into the first locking channel 142, so that the first pressing portion 152 can conveniently slide into the first locking channel 142. Similarly, the fourth guiding inclined surface 143 is not limited to a plane, but may be a smooth curved surface, which can also play a certain guiding role.

Preferably, the second locking device 141 further comprises a second potential energy component configured to store potential energy during the process that the second pressing portion 144 is pressed by the external force and rotates from the initial position to the pressing position; when the second pressing portion 144 is not subjected to external force or the external force is smaller than the driving force of the potential energy stored in the second potential energy component to the second pressing portion 144, the second potential energy component releases the potential energy to drive the second pressing portion 144 to rotate to the initial position. For the case that the external force applied to the second pressing portion 144 is smaller than the driving force of the second pressing portion 144 by the stored potential energy of the second potential energy component, reference may be made to the foregoing description of the first potential energy component, and this description is not repeated here.

[ example two ]

The sterile plate assembly, the surgical instrument, the power box and the surgical robot system according to the second embodiment of the present invention are basically the same as those of the first embodiment, and the same portions will not be described again, and only different points will be described below.

Referring to fig. 21 to 28, fig. 21 is a partial schematic view of a surgical instrument according to a second embodiment of the present invention; FIG. 22 is an exploded view of the surgical device illustrated in FIG. 21; FIG. 23 is a side view of the surgical instrument illustrated in FIG. 21; FIG. 24 is a transverse cross-sectional view of a surgical instrument according to a second embodiment of the present invention; FIG. 25 is a schematic view of a second embodiment of the present invention, after assembly of the surgical instrument with a sterile plate assembly; FIG. 26 is a transverse cross-sectional view of a second surgical instrument of the second embodiment of the present invention assembled with a sterile plate assembly; fig. 27 is a schematic view of a first elastic member according to a second embodiment of the present invention; fig. 28 is a partial schematic view of a sterility plate assembly in accordance with a second embodiment of the present invention.

In the second embodiment, the specific structure of the surgical device 14 is different from that of the first embodiment. Specifically, as shown in fig. 21 to fig. 26, in the surgical device 14 according to the second embodiment, the second pressing portion 144 is hinged to the second base plate 140, the second potential energy component includes a second elastic member 1492 or two second magnetic members arranged in opposite manner with the same polarity, and two ends of the second elastic member 1492 are respectively connected to the second pressing portion 144 and the second base plate 140; or the two second magnetic members are respectively connected to the second pressing portion 144 and the second substrate 140.

In an example, the second substrate 140 has a convex base 147, and the second pressing portion 144 is rotatably disposed at the convex end of the base 147 by a pin 1402. The first axis a is the axis of the pin 1402. Further, the second substrate 140 has a limiting hole 1403, and the limiting hole 1403 is used for the second holding portion 145 to penetrate through and can limit the rotation range of the second holding portion 145, so that the rotation range of the second pressing portion 144 is also limited between the initial position and the pressing position.

The second potential energy component comprising the second elastic member 1492 will be described as an example. The second elastic member 1492 can be a spring or a resilient piece, and one end of the second elastic member 1492 is connected to the base 147, and the other end is connected to the second pressing portion 144. When no external force is applied, the second elastic member 1492 pushes the second pressing part 144 toward the initial position by its own elastic force, and the second pressing part 144 is held at the initial position by the abutting of the second holding part 145 and the stopper hole 1403, as shown in the second locking device 141 on the right side of fig. 24 and 26. When the second pressing portion 144 is pressed by an external force and overcomes the elastic force of the second elastic member 1492, the second pressing portion 144 moves to the pressing position until the second holding portion 145 abuts against the other side of the position-limiting hole 1403, and the second pressing portion 144 reaches the pressing position, as shown in the second locking device 141 on the left side of fig. 24. In other embodiments, the second elastic member 1492 can be replaced by two second magnetic members with opposite poles, which can achieve similar effect.

In the aseptic board assembly 15 provided in the second embodiment, the specific structure of the first elastic member 154 is different from that of the first embodiment. Referring to fig. 27 and 28, alternatively, the first elastic element 154 may be an elastic folded part integrally formed with the first locking device 151, and the shape of the elastic folded part may be V-shaped, N-shaped, W-shaped, etc., and the material thereof may be a material with certain elasticity, such as a polymer material. Those skilled in the art can configure the cross-sectional shape and size and the elastic modulus of the first elastic member 154 according to actual needs. Further, the first elastic member 154 may also be folded to form a positioning region 1541 for snap-fastening with the positioning portion 1504 of the first substrate 150.

In summary, in the aseptic plate assembly, the surgical instrument, the power cartridge and the surgical robot system provided by the present invention, the aseptic plate assembly includes: the locking device comprises a first substrate and a first locking device arranged on the first substrate; the first locking device is movably arranged between a first locking position and a first unlocking position relative to the first base plate along a first direction; the first locking device comprises a first pressing part and a first clamping part which are connected, and when the first locking device is located at the first locking position, the first clamping part is used for being locked with a part corresponding to a first target object; when the first locking device is located at the first unlocking position, the first clamping part is used for unlocking a part corresponding to the first target object; the first pressing part is configured to be restricted by a second target object from moving in the first direction after the aseptic board assembly is used for being assembled and connected with the second target object, so that the first locking device is restricted to be in the first locking position. According to the configuration, after the sterile plate assembly, the surgical instrument and the power box are assembled and connected, the first pressing part of the sterile plate assembly is limited by the surgical instrument, so that the first locking device is located at the first locking position and reliably locked with the power box, the risk that the sterile plate assembly is accidentally unlocked with the power box due to misoperation in an operation can be avoided, the connection reliability is improved, and the safety and the reliability of the operation are ensured.
