Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a consistency calibration tooling. Background Technology
[0002] Minimally invasive surgery refers to a surgical procedure performed inside the human body using modern medical instruments and equipment such as laparoscopes and thoracoscopes. Compared to traditional surgical methods, minimally invasive surgery has advantages such as less trauma, less pain, and faster recovery. Surgical instruments used in minimally invasive surgery generally consist of three parts: an actuator, an instrument lever, and an end effector. The end effector is used for operations such as cutting and suturing diseased tissue. The end effector includes a wrist and an instrument head to ensure the freedom of movement of the end effector.
[0003] However, due to the limitations of incision size, surgical instruments used in minimally invasive surgery need to be highly precise and flexible to ensure that doctors can operate them accurately. In existing laparoscopic surgical robot systems, the surgical instruments used need to be calibrated according to specified calibration parameters before the operation to ensure that the accuracy of the surgical instruments meets the requirements.
[0004] Most existing surgical instruments are manually calibrated, requiring one person to hold the instrument while another calibrates it. Because the end effector of the surgical instrument has a certain degree of freedom, the calibration of the surgical instrument is relatively difficult, and each calibration requires a lot of effort and time from the staff.

When the instrument rod passes between the first groove and the first clamping part, the adjusting assembly moves away from the holding component until the limiting part abuts against the end structure of the instrument rod, achieving consistent positioning of the calibration fixture and the instrument rod. This invention achieves consistent calibration and correction of surgical instruments through the holding component, the holding assembly, and the limiting part, reducing the difficulty of surgical instrument calibration work and minimizing the effort and time spent by staff during instrument calibration. Meanwhile, the first and second clamping parts restrict the surgical instruments axially, eliminating the need for manual handling of the instruments and freeing up some labor when calibrating them.

[0033] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0034] See Figures 1 to 5 The consistency calibration fixture provided in this embodiment includes a mounting plate 100, a container 200, and an adjustment assembly 300.
[0035] The mounting plate 100 has a bearing surface extending horizontally. A container 200 is disposed on the bearing surface and has a first groove for accommodating an instrument rod 400, extending horizontally. An adjusting assembly 300 is disposed on the bearing surface and spaced apart from the container 200. The adjusting assembly 300 includes a first clamping part, a second clamping part, and a limiting part. The first clamping part, the limiting part, and the second clamping part are sequentially arranged in a direction away from the container 200. The first clamping part is disposed opposite to the first groove and is used to clamp the instrument rod 400. The second clamping part is used to clamp the end structure of the instrument rod 400. The limiting part is disposed on the side of the first clamping part opposite to the container 200 and is used to abut against the end of the instrument rod 400. The adjusting assembly 300 slides against the bearing surface to allow it to move closer to or further away from the first groove.
[0036] Specifically, in this embodiment, the mounting plate 100 forms a support structure, and the holding member 200 and the adjusting component 300 are both disposed on the bearing surface of the support member. After the configuration is completed, the first groove on the holding member 200 is opposite to the first clamping part, and the part of the instrument rod 400 near the control end can be placed into the first groove. The driving end of the instrument rod 400 is located on the side of the holding member 200 away from the adjusting component 300, and the end of the instrument rod 400 provided with the end effector 500 is placed into the first clamping part. The first groove and the first clamping part form a two-point fixation for the instrument rod 400.
[0037] Furthermore, in this embodiment, the first clamping part clamps the rod body of the instrument rod 400 to limit the circumferential degree of freedom of the instrument rod 400 and prevent the rod body from rotating. The second clamping part clamps the end structure of the instrument rod 400 (i.e., the end effector 500) to limit the pitch degree of freedom of the actuator connected to the end of the instrument rod 400.
[0038] When the instrument rod 400 passes between the first groove and the first clamping part and the first clamping part is not clamped with the second clamping part, the adjusting component 300 is moved away from the holding part 200 until the limiting part abuts against the end structure (end actuator 500) of the instrument rod 400, thereby realizing the positioning of the consistency calibration tooling and the instrument rod 400.
[0039] In this embodiment, the consistency of surgical instruments is calibrated through the holding component 200, the adjusting component 300, and the limiting part. The adjusting component 300 also enables the correction of the surgical instruments, reducing the difficulty of the calibration work and minimizing the effort and time required by staff. Simultaneously, the first and second clamping parts restrict the surgical instruments axially, eliminating the need for manual handling during calibration and correction, thus freeing up labor during the calibration process.
[0040] In this embodiment, the adjustment assembly 300 has a second groove 301. The adjustment assembly 300 includes a first locking member 310. The first clamping portion includes the second groove and the first locking member. The second groove 301 extends in the same direction as the first groove and is located on the extension line of the first groove. The bottom of the second groove 301 and the bottom of the first groove are on the same horizontal plane. The first locking member 310 is detachably disposed at the opening of the first groove, and the first locking member 310 and the first groove surround each other to form the first clamping portion.
[0041] Specifically, in this embodiment, the second groove 301 and the first groove of the container 200 maintain the same extension direction and are located on their extension line. At the same time, the bottoms of the two grooves are on the same horizontal plane to ensure that the instrument rod 400 can be smoothly inserted into the first groove and the second groove 301 when placed, thereby forming a guide structure for axial positioning of the instrument rod 400.
[0042] Furthermore, in this embodiment, the detachable first locking member 310 and the first groove body together form the first clamping part. When placing the instrument rod 400, the first locking member 310 can be removed first, making the first groove body completely open, so that the instrument rod 400 can be easily placed into the groove. After the instrument rod 400 is placed in place, the first locking member 310 is installed and locked, so that the first locking member 310 can press the instrument rod 400, thus quickly and reliably completing the clamping and fixing of the instrument rod 400 body. The operation is simple and the clamping is stable.
[0043] In this embodiment, the adjustment assembly 300 further includes a mounting portion 320 and a second locking member 330. The second clamping portion includes the mounting portion 320 and the second locking member 330. The mounting portion 320 extends in a horizontal direction. The second locking member 330 is provided with a third groove, and the second locking member 330 is fastened to the mounting portion 320 to form a second clamping portion with the mounting portion 320.
[0044] Specifically, in this embodiment, the third groove is a concave structure. When the second locking member 330 is fastened onto the mounting part 320, the third groove and the mounting part 320 cooperate to form the second clamping part. When placing the end effector 500 of the instrument rod 400, the second locking member 330 can be opened or removed first to facilitate placing the end effector 500 into the predetermined position on the mounting part 320, and then the second locking member 330 is fastened to lock and clamp it, thereby restricting the pitch freedom of the end effector 500 and preventing the pitch angle of the end effector 500 from not meeting expectations.
[0045] In this embodiment, the adjustment assembly 300 further includes a first adjustment member 331 and a second adjustment member 332. The first adjustment member 331 is detachably disposed at the bottom of the third groove. The second adjustment member 332 is disposed at the mounting portion 320 and is opposite to the first adjustment member 331. The first adjustment member 331 and the second adjustment member 332 are used to clamp the end structure of the instrument rod 400 and fix its angle.
[0046] The first adjusting member 331 and the second adjusting member 332 form a clamping structure that directly contacts the end effector 500 within the covering space of the third groove. Since the first adjusting member 331 is detachably set at the bottom of the third groove, the thickness of the first adjusting member 331 can be adjusted according to different scenarios, thereby ensuring that both the first adjusting member 331 and the second adjusting member 332 can directly contact and constrain specific parts of the end effector 500 (such as the connecting wrist or the end effector 500 body).
[0047] This structure enables the consistency calibration fixture provided in this embodiment to be applicable to a variety of instruments of different specifications, improving versatility and enabling it to be securely locked in the required specific angle and posture, eliminating possible angle deviation or shaking of the end effector 500 during the calibration process.
[0048] In this embodiment, the first adjusting member 331 is set at the bottom of the third groove by means of screw locking, and the second adjusting member 332 is also set at the mounting part 320 by means of screw locking.
[0049] In this embodiment, the adjustment assembly 300 further includes an opening and closing limiting member 340. The opening and closing limiting member 340 is disposed on the mounting portion 320 and located on the side of the second locking member 330 away from the first locking member 310. The opening and closing limiting member 340 is used to limit the closing angle of the end structure of the instrument rod 400.
[0050] In consistency calibration (especially involving the position and attitude of the end effector 500), the closed state (angle) of the end effector 500 is one of the key variables affecting calibration accuracy. If the closing angle is inconsistent or cannot be precisely fixed, significant errors will be introduced. In this embodiment, the opening and closing limit member 340 forms a physical limit when the moving part of the end effector 500 closes inward, thereby blocking the moving opening and closing part. The opening and closing limit member 340 forms a rigid mechanical limit on the opening and closing part of the end effector 500 through physical limitation, so that the closing angle of the opening and closing part of the end effector 500 is precisely and stably limited to a preset, uniform standard value, thereby eliminating the uncertainty in this degree of freedom.
[0051] In this embodiment, the adjusting assembly 300 further includes a sliding seat 350. A second groove 301 is disposed at one end of the sliding seat 350, and connecting holes 312 with internal threads are provided on both sides of the groove opening of the second groove 301. The first locking member 310 is detachably connected to the connecting holes 312 by bolts 311.
[0052] The second groove 301 is located at one end of the sliding seat 350. The first locking member 310 is connected to the connecting hole 312 by bolt 311 to achieve a detachable connection. When installing and removing the first locking member 310, only the bolt 311 needs to be tightened or loosened, which has a high loading and unloading efficiency. After the bolt 311 is tightened, the first locking member 310 locks the instrument rod 400 more securely and is not easy to loosen.
[0053] Furthermore, in this embodiment, the connecting hole 312 is a stepped hole. The adjusting assembly 300 also includes an elastic reset member. The elastic reset member is disposed on the stepped surface of the stepped hole and abuts against the first locking member 310.
[0054] Specifically, in this embodiment, the elastic reset member is a spring. The spring is disposed on the stepped surface of the stepped hole and sleeved on the bolt 311 in the connecting hole 312. The top of the spring always abuts against the bottom surface of the first locking member 310.
[0055] During the tightening of bolt 311, the first locking element 310 gradually compresses the spring. When the instrument needs to be replaced after use, the spring can provide a reaction force, eliminating the need to completely disassemble the first locking element 310, making it more convenient to use.
[0056] In this embodiment, the adjusting assembly 300 further includes an abutment. The abutment is disposed on the side of the first locking member 310 opposite to the first groove, and the side of the abutment opposite to the first locking member 310 is the limiting part.
[0057] In this embodiment, after the instrument rod 400 is inserted into the first groove, the second groove 301, and the third groove, the adjusting component 300 moves away from the holding component 200. The side of the abutment member facing away from the first locking member 310 abuts against the end structure (end actuator 500) of the instrument rod 400, thereby realizing the positioning of the consistency calibration fixture and the instrument rod 400. This ensures that the end of the instrument rod 400 (the base of the end actuator 500) can be accurately and repeatably positioned on the same reference plane in each abutment operation, establishing a reliable reference position for subsequent consistency calibration and improving the accuracy of the calibration parameters.
[0058] In this embodiment, the limiting part is an arc-shaped limiting surface 351. The top surface of the abutment is provided with an arc-shaped groove that connects to the bottom of the second groove 301, and the shape of the arc-shaped limiting surface 351 fits the end structure of the instrument rod 400.
[0059] The end of the instrument rod 400 (the part connecting to the end effector 500) is usually a complex curved surface that is not planar (such as a cylindrical surface, a spherical surface, or a specific contour). In this embodiment, the arc-shaped limiting surface 351 provides a highly consistent surface contact, realizing the precise positioning and constraint of the end of the instrument rod 400 in all degrees of freedom (especially rotational degrees of freedom), rigidly and repeatably locking it in the only correct position and orientation, completely eliminating the positioning ambiguity or error caused by the complex shape of the end, providing unprecedented end reference accuracy for consistency calibration, and completely and accurately wrapping the end of the instrument rod 400 within the preset arc-shaped limiting surface 351.
[0060] In this embodiment, the consistency calibration fixture also includes a slider 360. A slide rail 110 is provided on the bearing surface, and the container 200 is disposed in the slide rail 110. The slider 360 is disposed in the slide rail 110 and is connected to the adjustment assembly 300 in a transmission manner.
[0061] In this embodiment, the container 200 and the slider 360 are both located in the same slide rail 110. The two share the same slide rail 110, which ensures that the container 200 and the adjustment component 300 always maintain a precise relative positional relationship during movement. This eliminates the need for cumbersome independent alignment operations and greatly improves adjustment efficiency and accuracy.
[0062] Specifically, in this embodiment, the slider 360 is located at the bottom of the sliding seat 350 so that the sliding seat 350, the first locking member 310, the second locking member 330, the first adjusting member 331, the second adjusting member 332, and the opening and closing limiting member 340 can all slide on the slide rail 110 via the slider 360.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
