Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and in particular to an instrument traction rope installation tool. Background Art

[0002] Minimally invasive surgery refers to a surgical procedure performed within the human body using modern medical instruments such as laparoscopes and thoracoscopes, as well as related equipment. Compared to traditional surgical methods, minimally invasive surgery offers advantages such as less trauma, less pain, and faster recovery. However, the limitations of incision size make the operation significantly more difficult. Furthermore, the fatigue and tremors of the surgeon during prolonged procedures are amplified, which has become a key factor hindering the development of minimally invasive surgical techniques. With the development of robotics, a new technology in the field of minimally invasive medicine has emerged that overcomes these shortcomings while inheriting their advantages: minimally invasive surgical robotics.

[0003] A typical minimally invasive surgical robot consists of a doctor's console, a patient operating platform, and a display device. The surgeon operates an input device at the console and transmits the input to the patient operating platform, which is connected to the remotely operated surgical instruments. Surgical instruments typically include surgical scissors and bipolar forceps. To minimize the size of the device before it enters the human body, the surgical scissors are typically pulled by a wire rope.

[0004] For example, Chinese utility model patent CN 217566303 U discloses a bipolar forceps and a minimally invasive surgical robot, in which a wire rope is pre-tightened and arranged in an instrument box. The wire rope is transmitted through the instrument shaft and connected to the end of the instrument. By pulling the wire rope, the driving force can be transmitted to the clamping mechanism, thereby realizing the pitch, yaw and clamping freedom movement of the clamping mechanism.

[0005] During the production process of surgical instruments, it is necessary to install a traction rope on the instrument box. At the same time, in order to achieve flexible and precise control of the instrument, there are strict requirements for the pre-tightening force of the wire rope. The pre-tightening force needs to be controlled within a fixed range, and the pre-tightening force of each wire rope is required to be the same. Currently, common traction rope installation devices and pre-tightening force detection devices are generally installed and inspected manually. During the installation of the traction rope, the pre-tightening state of the traction rope is unstable due to the certain degree of freedom of the end of the instrument. In the pre-tightening force detection device of the traction rope, some components are combined with electrical devices. There are also sensors for detecting wire ropes on the market. Generally, multiple sensors (pressure sensors, displacement sensors) are used in combination. However, due to the small size of the instrument itself, the wire rope is precisely wound and has a certain elastic reset force, the means of manual direct detection cannot accurately test the pre-tightening force of each wire rope. Medical instruments have high requirements for each component, so tooling that can accurately measure and is easy to install is required. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides an apparatus traction rope installation tool with convenient traction rope installation and high pre-tightening force accuracy.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0008] The present application provides an instrument traction rope installation tool, comprising a base plate, on which a first fixing component for clamping and limiting an instrument rod is fixed;

[0009] The bottom plate is provided with a second fixing component on one side of the first fixing component, which can move toward or away from the first fixing component;

[0010] Wherein, the second fixing assembly can clamp and limit the connection wrist between the instrument rod and the instrument head and can limit the opening and closing of the instrument head;

[0011] Its beneficial effect is that during the winding of the traction rope on the instrument plate, the axial movement of the instrument rod, the freedom of movement of the wrist connecting the instrument rod and the instrument head, and the opening and closing state of the instrument head are limited by the first fixing component and the second fixing component. That is, the freedom of the execution end of the instrument component is completely restricted during the winding of the traction rope, so that the operator is not affected by the elastic reset force formed by the posture state of the instrument head when winding the traction rope on the instrument plate, thereby improving the pre-tightening force setting accuracy of the traction rope and the subsequent pre-tightening force detection and adjustment accuracy. At the same time, during the traction rope winding stage, the limit block does not limit the rotational freedom of the instrument relative to the instrument rod, thereby facilitating the operator to adjust the angle of the instrument plate to improve the traction rope winding efficiency.

[0012] It is further defined that the above-mentioned instrument traction rope installation tool, wherein the bottom plate is provided with a limit block on a side of the first fixing component away from the second fixing component, and the limit block can move toward or away from the side of the first fixing component;

[0013] The movement directions of the limit block and the second fixing assembly on the base plate are located in the same straight line, and the limit block can abut against the first fixing assembly and the instrument plate to limit the rotation of the instrument plate relative to the instrument rod.

[0014] It is further defined that the above-mentioned instrument traction rope installation tool, wherein the bottom plate is provided with a first slide groove and a second slide groove, a first slide is slidably connected in the first slide groove, and a second slide is slidably connected in the second slide groove;

[0015] The limit block is fixedly arranged on the first slide, the second fixing assembly is fixedly arranged on the second slide, and at least one fixing point is provided between the first slide, the second slide and the bottom plate.

[0016] It is further defined that the above-mentioned instrument traction rope installation tool further includes a pre-tightening force detection component for detecting the pre-tightening force of the traction rope on the instrument plate, the pre-tightening force detection component includes a cross slide fixedly arranged on the first slide and located on the side of the limit block away from the first fixed component, and a connecting seat is fixedly provided on the execution output end of the cross slide;

[0017] A pressure sensor is fixed on the connecting seat, and a thimble for resisting the traction rope is connected to the sensing end of the pressure sensor;

[0018] The execution output end of the cross slide can move on a horizontal plane along the axial direction of the instrument rod and in a direction perpendicular to the axial direction of the instrument rod;

[0019] The beneficial effect is that, since the freedom of the actuator components is fully restricted during the detection process, the influence of the actuator posture on the preload of the traction rope is eliminated. With the cooperation of the ejector and the cross slide, the preload of the traction rope at different positions can be detected through the pressure sensor, which not only has high detection efficiency but also strong detection accuracy and reliability.

[0020] It is further defined that in the above-mentioned apparatus traction rope installation tool, the first fixing component includes:

[0021] A support seat, fixedly arranged on the bottom plate;

[0022] An opening and closing clamp is hingedly arranged on the end surface of the support base away from the bottom plate;

[0023] A buckle assembly is provided between the support base and the opening and closing clamp, and is used to maintain the clamping state of the support base and the opening and closing clamp;

[0024] Wherein, the support seat and the opening and closing clamp are respectively provided with two first limiting grooves on the opposite side end surfaces in the clamping state, and the groove walls of the two first limiting grooves can abut against the instrument rod to limit the rotation and axial movement freedom of the instrument rod;

[0025] Its beneficial effect is that the rotation and axial movement freedom of the instrument rod are restricted by cooperating with the support seat and the opening and closing clamp, and the clamping and opening states of the opening and closing clamp are quickly adjusted through the snap-fit ​​assembly, thereby greatly improving the limiting efficiency of the instrument rod.

[0026] It is further defined that the above-mentioned instrument traction rope installation tooling, wherein the end surface of the limit block close to the support seat is provided with a limit groove;

[0027] The groove wall of the position-limiting groove can abut against the end surface of the instrument plate away from the support seat and the end surface of the instrument plate close to the bottom plate;

[0028] The beneficial effect is that the limiting groove can not only limit the rotation of the instrument plate relative to the instrument rod, but also limit the movement of the instrument plate along the axial direction of the instrument rod after the relative position between the limiting block and the support seat is fixed, thereby further ensuring the position stability of the instrument plate, facilitating the subsequent pre-tightening force detection of the traction rope on the instrument plate, and improving the accuracy of the subsequent pre-tightening force detection of the traction rope.

[0029] It is further defined that the above-mentioned instrument traction rope installation tool, wherein the second fixing assembly includes a first base fixedly arranged on the bottom plate, an adjustment rod is bolted to the first base, and a driven block is connected to the adjustment rod;

[0030] A second base is fixed on the first base, and the rotation of the adjusting rod can drive the driven block to move toward or away from the second base;

[0031] Wherein, the driven block can abut against the corresponding side end surface of the second base, and the axial direction of the adjustment rod is perpendicular to the axial direction of the instrument rod;

[0032] The end surface of the driven block close to the second base and / or the end surface of the second base close to the driven block are provided with a second limiting groove for accommodating the instrument rod and connecting the wrist;

[0033] Its beneficial effect is that by adjusting the distance between the driven block and the second base through the adjustment rod, it can not only ensure the reliability of the clamping limit of the instrument rod and the instrument head connecting wrist, but also can match the execution instrument components of different specifications, and has stronger applicability.

[0034] It is further defined that the above-mentioned instrument traction rope installation tool is provided with an adjustment groove on the first base, and a connecting block is slidably provided in the adjustment groove;

[0035] Wherein, the adjusting rod is fixedly connected to the connecting block, and the driven block is fixedly arranged on the connecting block.

[0036] It is further defined that in the above-mentioned instrument traction rope installation tool, two limit screws are respectively threadedly connected on the second base and the driven block, and the two limit screws can respectively abut and limit the opening and closing parts of the instrument head;

[0037] Its beneficial effect is that by rotating and adjusting the position of the two limit screws, the opening and closing state of the instrument head can be limited. When the pre-tightening force of the traction rope is detected, the two limit screws respectively resist the opening and closing parts of the instrument head to keep it in a closed state, thereby ensuring that the pre-tightening force of the traction rope is constant. The accuracy of the detection of the pre-tightening force of the traction rope is guaranteed by completely limiting the execution of the instrument assembly.

[0038] It is further defined that the above-mentioned instrument traction rope installation tool further includes a limit plate that is detachably fixedly mounted on the instrument plate, and the limit plate is provided with a through-hole capable of engaging with the winding shaft head and limiting the rotation of the winding shaft head;

[0039] The winding shaft head is coupled to the rotating sleeve on the instrument plate and is used to rotate and adjust the pre-tightening force of the traction rope on the rotating sleeve at the corresponding position;

[0040] Its beneficial effect is that the rotational freedom of the winding shaft head on the instrument plate is limited by the limit plate, so that after the pre-tensioning force of the traction rope on the instrument plate is adjusted, the position of the winding shaft head reaches the specified posture. Since the instrument head is in a closed posture at this time, the execution instrument assembly maintains a standard state, ensuring that it is always in this standard state during subsequent use, and there is no need for secondary adjustment during use to avoid errors.

DETAILED DESCRIPTION

[0055] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are 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 are within the scope of protection of this application.

[0056] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0057] The following is a detailed description of the equipment traction rope installation tool provided in the embodiment of the present application through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0058] The embodiment of the present application provides a tool for installing a traction rope for an instrument, such as Figures 1 to 8 As shown, it includes a base plate 100, on which a first fixing component 300 for clamping and limiting the instrument rod 620 is fixed, and a first slide 210 and a second slide 400 are respectively provided on both sides of the first fixing component 300 on the base plate 100, which can move toward or away from one side of the first fixing component 300, wherein the sliding directions of the first slide 210 and the second slide 400 on the base plate 100 are located in the same straight line and the sliding strokes do not overlap with each other.

[0059] A limit block 230 is fixedly provided on the first slide 210, which can abut against the first fixed component 300 and is used to limit the rotation of the instrument plate 610. A second fixed component 500 is fixedly provided on the second slide 400, which can clamp and limit the instrument rod 620 and the instrument head 630 connecting wrist and can limit the opening and closing of the instrument head 630.

[0060] It should be noted that the instrument rod 620 is set on the instrument plate 610, and the instrument head 630 is connected to the end of the instrument rod 620 away from the instrument plate 610, and the movement of the instrument head 630 is controlled by the traction rope. The end of the traction rope away from the instrument head 630 passes from the instrument rod 620 to the side of the instrument plate 610 and is wrapped around the rotating sleeve on the instrument plate 610. The staff only needs to operate the tensioning and loosening changes of the traction rope on the instrument plate 610 to achieve movement control of the instrument head 630.

[0061] It can be understood that when the instrument rod 620 is clamped by the first fixing assembly 300, its freedom of rotation and axial movement is restricted by the first fixing assembly 300. At this time, the instrument plate 610 connected to the instrument rod 620 is located on the side of the first fixing assembly 300 close to the first slide 210, and the limit block 230 does not interfere with the first fixing assembly 300. The second slide 400 can move toward or away from the first fixing assembly 300 to adjust the relative position between the second fixing assembly 500 and the instrument rod 620 and the instrument head 630, so that the second fixing assembly 500 clamps the connecting wrist of the instrument rod 620 and the instrument head 630. At this time, the swing of the instrument head 630 relative to the instrument rod 620 is restricted, and the axial movement of the instrument rod 620 is further restricted. When the second fixing assembly 500 limits the opening and closing state of the instrument head 630, the end of the traction rope on the instrument plate 610 is not affected by the elastic reset force formed by the posture state of the instrument head 630. Since the limit block 230 does not limit the rotational freedom of the instrument plate 610 relative to the instrument rod 620, it is convenient for the operator to wind the traction rope on the instrument plate 610. When the traction rope is wound, the first slide 210 can move toward or away from the side of the first fixing assembly 300 so that the limit block 230 contacts the first fixing assembly 300. At this time, the end face of the instrument plate 610 close to the base plate 100 contacts the end face of the limit block 230 away from the ground, thereby limiting the rotational freedom of the instrument plate 610 relative to the instrument rod 620, which is convenient for the operator to subsequently detect the pre-tightening force of the traction rope.

[0062] Of course, the first slide 210 and the second slide 400 are both provided with a limiting part for limiting the relative position between them and the base plate 100. When the limiting block 230 conflicts with the first fixing component 300 or the second fixing component 500 limits the instrument rod 620 and the instrument head 630, the relative position of the first slide 210, the second slide 400 and the base plate 100 is limited by the limiting part, thereby ensuring the limiting stability of the limiting block 230 on the instrument plate 610 and the second fixing component 500 on the instrument rod 620 and the instrument head 630.

[0063] In an embodiment of the present application, the above-mentioned instrument traction rope installation tool is used. During the process of winding the traction rope on the instrument plate 610, the first fixing component 300 and the second fixing component 500 are used to limit the axial movement of the instrument rod 620, the freedom of movement of the wrist connecting the instrument rod 620 and the instrument head 630, and the opening and closing state of the instrument head 630. That is, the freedom of the execution end of the instrument component is completely restricted during the winding of the traction rope, so that the operator is not affected by the elastic reset force formed by the posture state of the instrument head 630 when winding the traction rope on the instrument plate 610, thereby improving the preload setting accuracy of the traction rope and the subsequent detection and adjustment accuracy of the preload.

[0064] In a preferred embodiment, as Figures 1 to 4 As shown, a first sliding groove 110 is provided on the bottom plate 100 , and the first sliding platform 210 is slidably connected and disposed in the first sliding groove 110 .

[0065] The first slide 210 is provided with screw holes. When the limiting block 230 contacts the first fixing assembly 300 , the first slide 210 is bolted to the base plate 100 through the screw holes to achieve fixation of the relative position between the first slide 210 and the base plate 100 .

[0066] The first slide 210 is manually controlled by an operator to slide in the first slide groove 110. It can be understood that the movement control form of the first slide 210 is not limited to the above-mentioned one. For example, a telescopic device can be set on the base plate 100, and the first slide 210 is fixedly connected to the telescopic end of the telescopic device. At this time, the first slide 210 is automatically driven, which further improves the limiting efficiency of the execution end of the instrument component.

[0067] In a preferred embodiment, as Figures 1 to 4 As shown, the first fixing assembly 300 includes a support base 310 fixedly disposed on the base plate 100 , and an opening and closing clamp 320 is hingedly provided on the end surface of the support base 310 away from the ground.

[0068] A first limiting groove 330 is provided at the corresponding positions of the end surface of the support seat 310 away from the base plate 100 and the end surface of the opening and closing clamp 320 close to the support seat 310. When the opening and closing clamp 320 swings toward the side close to the support seat 310 (in a closed state), the first limiting groove 330 on the support seat 310 and the first limiting groove 330 forms a clamping limiting hole.

[0069] A buckling assembly 340 is further provided between the support base 310 and the opening and closing clip 320 for maintaining the support base 310 and the opening and closing clip 320 in a closed state.

[0070] The first limiting groove 330 is specifically set to a semicircular arc groove, and the clamping limiting hole formed by the two first limiting grooves 330 at the corresponding positions is a circular hole. It can be understood that the first limiting groove 330 and the snap-fit ​​assembly 340 cooperate with each other and realize the clamping and limiting of the instrument rod 620 through the first limiting groove 330. The setting form of the first limiting groove 330 is not limited to the above-mentioned one. For example, the first limiting groove 330 can also be set to other cross-sectional shapes, as long as it can ensure the friction of the inner wall of the first limiting groove 330 on the instrument rod 620 when the opening and closing clamp 320 is closed.

[0071] Similarly, in order to increase the friction between the inner wall of the first limiting groove 330 and the instrument rod 620, a rubber layer or other anti-slip layer that can increase the friction between the inner wall of the first limiting groove 330 and the instrument rod 620 can be further provided on the inner wall of the first limiting groove 330.

[0072] In the embodiment of the present application, the above-mentioned instrument traction rope installation tool is used, and the rotation and axial movement freedom of the instrument rod 620 are restricted by cooperating with the support seat 310 and the opening and closing clamp 320, and the clamping and opening states of the opening and closing clamp 320 are quickly adjusted through the snap-fit ​​assembly 340, thereby greatly improving the limiting efficiency of the instrument rod 620.

[0073] It can be understood that the snap-fit ​​assembly 340 has a certain tolerance for the closed state between the opening and closing clamp 320 and the support seat 310, that is, the snap-fit ​​assembly 340 is specifically configured to limit the swing of the opening and closing clamp 320 relative to the support seat 310 through elastic force. Even if the opening and closing clamp 320 does not completely contact the support seat 310, the snap-fit ​​assembly 340 can still limit the swing of the opening and closing clamp 320 to the side away from the support seat 310, thereby being suitable for the clamping limit of instrument rods 620 with different diameters.

[0074] In a preferred embodiment, as Figure 5 As shown, a limiting groove 231 is provided on the end face of the limiting block 230 close to the support seat 310. When the limiting block 230 contacts the support seat 310, the instrument plate 610 is located in the limiting groove 231 and the end face close to the base plate 100 contacts the inner wall of the limiting groove 231 close to the base plate 100, the end face away from the support seat 310 contacts the inner wall of the limiting groove 231 away from the support seat 310, and the end face close to the support seat 310 contacts the corresponding side end face of the support seat 310.

[0075] In the application embodiment, the above-mentioned instrument traction rope installation tooling is used, and the limiting groove 231 can not only limit the rotation of the instrument plate 610 relative to the instrument rod 620, but also, after the relative position between the limiting block 230 and the support seat 310 is fixed, the axial movement of the instrument plate 610 along the instrument rod 620 can be limited, further ensuring the position stability of the instrument plate 610, facilitating the subsequent pre-tightening force detection of the traction rope on the instrument plate 610, and improving the accuracy of the subsequent pre-tightening force detection of the traction rope.

[0076] In a preferred embodiment, as Figures 1 to 3 As shown, a second sliding groove 120 is provided on the bottom plate 100 , and the second slide 400 is slidably connected and disposed in the second sliding groove 120 .

[0077] The second slide 400 is provided with screw holes. After the position of the second fixing assembly 500 is adjusted, the second slide 400 is bolted to the base plate 100 through the screw holes to achieve fixation of the relative position between the second slide 400 and the base plate 100.

[0078] The second slide 400 is manually controlled by an operator to achieve sliding in the second slide groove 120. It can be understood that the movement control form of the second slide 400 is not limited to the above-mentioned one. For example, a telescopic device can be set on the base plate 100, and the second slide 400 can be fixedly connected to the telescopic end of the telescopic device. At this time, the second slide 400 is automatically driven, which further improves the limiting efficiency of the execution end of the instrument component.

[0079] In a preferred embodiment, as Figures 1 to 3 、 Figure 5 As shown, the second fixing assembly 500 includes a first base 510 fixedly set on the base plate 100, an adjustment groove 540 is provided on the first base 510, a connecting block 530 is slidably provided in the adjustment groove 540, and an adjustment rod 520 fixedly connected to the connecting block 530 is bolted on the first base 510.

[0080] The rotation of the adjusting rod 520 can drive the connecting block 530 to slide in the adjusting groove 540 , and the sliding direction of the connecting block 530 in the adjusting groove 540 is perpendicular to the axial direction of the instrument rod 620 .

[0081] A second base 560 is fixedly provided on the end face of the first base 510 away from the base plate 100, a follower block 550 that can interfere with the second base 560 is fixed on the end face of the connecting block 530 away from the base plate 100, and a second limiting groove 580 for accommodating the instrument rod 620 and the instrument head 630 for connecting to the wrist is provided on the end face of the second base 560 close to the follower block 550.

[0082] It can be understood that when the wrist connecting the instrument rod 620 and the instrument head 630 is located in the second limiting groove 580, the rotation of the adjusting rod 520 can drive the driven block 550 to move toward the side close to the second base 560. At this time, the freedom of movement of the wrist connecting the instrument rod 620 and the instrument head 630 is restricted due to the clamping action of the outer end face of the driven block 550 and the inner wall of the second limiting groove 580.

[0083] It can be understood that the follower block 550 and the second base 560 are mainly used to clamp the instrument rod 620 and the instrument head 630 to connect to the wrist, and the setting form of the second limiting groove 580 is not limited to the above-mentioned one. For example, the second limiting groove 580 can be set only on the end face of the follower block 550 close to the second base 560, or the second limiting groove 580 can be set on the corresponding side end faces of the follower block 550 and the second base 560, as long as the freedom of movement of the instrument rod 620 and the instrument head 630 connected to the wrist can be restricted.

[0084] Similarly, in order to improve the limiting effect of the follower block 550 and the second base 560 on the automatic movement of the wrist connected to the instrument rod 620 and the instrument head 630, a rubber layer or other anti-slip layer that can increase the friction between the wrist connected to the instrument rod 620 and the instrument head 630 can be further provided on the inner wall of the second limiting groove 580 or the corresponding side end face of the follower block 550.

[0085] In the application embodiment, the above-mentioned instrument traction rope installation tool is used, and the distance between the driven block 550 and the second base 560 is adjusted by adjusting the adjustment rod 520. This not only ensures the reliability of the clamping and limiting of the instrument rod 620 and the instrument head 630 connected to the wrist, but also can match the execution instrument components of different specifications, and has stronger applicability.

[0086] It can be understood that the distance adjustment form between the driven block 550 and the second base 560 is not limited to the above-mentioned one. For example, the second base 560 can be fixedly set on the base plate 100, and the driven block 550 can be connected to the telescopic end of the telescopic device. That is, the distance between the driven block 550 and the second base 560 is automatically adjusted by the telescopic device, thereby improving the clamping and limiting efficiency of the wrist connection of the instrument rod 620 and the instrument head 630. As long as the distance adjustment between the driven block 550 and the second base 560 can be achieved, it will not be elaborated here.

[0087] In a preferred embodiment, as Figures 1 to 3 、 Figure 5 As shown, two limiting screws 570 are respectively threadedly connected to the second base 560 and the driven block 550 , wherein the two limiting screws 570 are coaxial or axially parallel and are both located on the same horizontal plane as the second limiting groove 580 .

[0088] By rotating and adjusting the positions of the two limit screws 570, the opening and closing parts of the instrument head 630 can be limited respectively, that is, the opening and closing states of the instrument head 630 can be limited. When the preload force of the traction rope is detected, the two limit screws 570 respectively resist the opening and closing parts of the instrument head 630 to keep it in a closed state, thereby ensuring that the preload force of the traction rope is constant. The accuracy of the detection of the preload force of the traction rope is guaranteed by completely limiting the execution of the instrument assembly.

[0089] It is understandable that the opening and closing state restrictions of the instrument head 630 are not limited to the above-mentioned form. For example, a kit that matches the closed state contour of the instrument head 630 can be directly set. During the traction rope preload detection process, the kit is installed on the instrument head 630 to maintain its closed state. As long as the preload force of the traction rope can be kept constant, it will not be elaborated here.

[0090] In a preferred embodiment, as Figures 1 to 3 、 Figure 7As shown, the first slide 210 is further provided with a pre-tightening force detection component 220 for detecting the pre-tightening force of the traction rope on the instrument plate 610.

[0091] The preload force detection assembly 220 includes a cross slide 221 fixedly set on the first slide 210 and located on the side of the limit block 230 away from the first fixed assembly 300. A connecting seat 222 is fixedly provided on the execution output end of the cross slide 221. A pressure sensor 224 is fixedly provided on the end face of the connecting seat 222 close to the first fixed assembly 300. A connecting piece 225 is fixedly provided on the sensing end of the pressure sensor 224. A pin 226 is connected to the end of the connecting piece 225 away from the pressure sensor 224.

[0092] Among them, the execution output end of the cross slide 221 can move along the axial direction of the instrument rod 620 and perpendicular to the axial direction of the instrument rod 620 on the horizontal plane, thereby adjusting the position of the ejector pin 226 relative to the traction rope on the instrument plate 610.

[0093] Before the traction rope is installed, the position of the second fixing component 500 is adjusted through the second slide 400 according to the length of the instrument rod 620, and the operator limits the instrument rod 620 and the instrument head 630 through the first fixing component 300 and the second fixing component 500. At this time, the instrument rod 620 and the instrument head 630 are fixed, and the instrument plate 610 can also rotate freely relative to the instrument rod 620, which is convenient for the worker to wind the traction rope (loosely wound state).

[0094] After the traction rope is wound around the instrument plate 610 , the first slide 210 moves in the first slide groove 110 until the limit block 230 contacts the first fixing assembly 300 , and the limit groove 231 cooperates with the support seat 310 to fix the instrument plate 610 .

[0095] Since there are multiple traction ropes on the instrument plate 610, and each traction rope is not in the same plane and has different angles and positions, the laboratory pre-experiments and adjusts the values ​​before large-scale testing of workers. Each traction rope can correspond to a set of moving coordinate values ​​of the pre-tension detection component 220.

[0096] After the worker adjusts the cross slide 221 to the preset position according to the standard (at this time, the thimble 226 corresponds to a traction rope), the thimble 226 contacts the traction rope at the corresponding position and senses the pressure of the traction rope through the pressure sensor 224. The pressure sensor 224 is connected to the external display. Through the value on the display, the pre-tightening force of the traction rope can be understood more intuitively and accurately. If the pre-tightening force of the traction rope is unqualified, the pre-tightening force of the traction rope is adjusted by rotating the rotating sleeve at the corresponding position. If the pre-tightening force of the traction rope reaches the specified range, it indicates that it is qualified.

[0097] After one traction rope is tested, the cross slide 221 is readjusted to test the next traction rope until each traction rope on the instrument plate 610 is tested. The execution instrument assembly is disassembled to prepare for completing the installation and testing of the traction rope of the next execution instrument assembly.

[0098] In the embodiment of the present application, the above-mentioned instrument traction rope installation tooling is used. Since the freedom of the executing instrument components is fully restricted during the detection process, the influence of the executing instrument posture on the preload force of the traction rope is eliminated. With the cooperation of the ejector pin 226 and the cross slide 221, the preload force of the traction rope at different positions can be detected through the pressure sensor 224, which not only has high detection efficiency but also has strong detection accuracy and reliability.

[0099] In a preferred embodiment, as Figures 1 to 3 、 Figure 7 As shown, the connecting seat 222 is provided with reinforcing ribs 223 for improving its own strength.

[0100] In a preferred embodiment, as Figure 7 、 Figure 8 As shown, an arc groove 227 for resisting the traction rope is provided on one end of the ejector pin 226 away from the pressure sensor 224.

[0101] In a preferred embodiment, as Figures 9 to 12 As shown, it also includes a limiting plate 700 for maintaining the pre-tightening force of the traction rope on the instrument plate 610.

[0102] The limiting plate 700 includes a plate body 710 that can be installed on the instrument plate 610 . The plate body 710 is provided with an embedding groove 720 that can be embedded with the winding shaft head 611 and is used to rotationally limit the winding shaft head 611 on the instrument plate 610 .

[0103] It can be understood that the winding shaft head 611 is coupled to the rotating sleeve on the instrument plate 610. By rotating the winding shaft head 611, the preload force of the traction rope on the rotating sleeve can be adjusted. When the groove 720 restricts the rotation of the winding shaft head 611, the preload force of the traction rope on the rotating sleeve can remain stable.

[0104] Among them, in order to ensure that the groove 720 limits the rotation of the winding shaft head 611, the winding shaft head 611 is set to a non-rotating body shape, and the groove 720 matches the shape of the winding shaft head 611. When the plate body 710 is installed on the instrument plate 610 and the winding shaft head 611 is engaged with the groove 720, the rotation of the winding shaft head 611 is restricted under the interference of the inner wall of the groove 720.

[0105] In the embodiment of the present application, the above-mentioned instrument traction rope installation tool is used, and the rotational freedom of the winding shaft head 611 on the instrument plate 610 is limited by the limit plate 700, so that after the pre-tightening force of the traction rope on the instrument plate 610 is adjusted, the position of the winding shaft head 611 reaches the specified posture. Since the instrument head 630 is in a closed posture at this time, the execution instrument assembly maintains a standard state, ensuring that it is always in this standard state during subsequent use, and there is no need for secondary adjustment during use to avoid errors.

[0106] It is understandable that the installation method of the plate body 710 on the instrument plate 610 can be set to be a bolt connection, a buckle connection or other detachable connection methods.

[0107] In a preferred embodiment, as Figure 9 、 Figure 10 As shown, a plurality of limiting plates 700 are installed on the instrument plate 610 . Similarly, a plurality of embedding grooves 720 can be set on one plate body 710 based on the position and number of the winding shaft heads 611 .

[0108] The limiting plate 700 can limit the rotation of all the rotating sleeves on the instrument plate 610, thereby ensuring that the pre-tightening force of all the traction ropes on the instrument plate 610 is in a stable state.

[0109] In a preferred embodiment, as Figure 12 As shown, a stepped groove 730 connected to the embedded groove 720 is provided on the end face of the plate body 710 close to the instrument plate 610. The stepped groove 730 is used to avoid the rotating connection between the winding shaft head 611 and the instrument plate 610, and at the same time increases the matching depth with the winding shaft head 611, so that the limiting plate 700 can limit the winding shaft head 611 more firmly.
