Description

Technical Field

[0001] This invention relates to the field of medical device technology, and further to a fixation component and a fixation bracket adapter. Background Technology

[0002] Currently, some medical procedures require fixing medical devices to equipment or devices first. However, some fixing methods are inflexible and arbitrary, which can easily lead to problems such as the medical devices not being firmly fixed or easily coming loose. This cannot provide a stable fixing component, which can cause unnecessary waste of time for medical staff and affect the patient's treatment time. More seriously, it may even lead to the displacement of the examination or surgical position, which will have a negative impact on the patient's physical condition.

[0003] In conclusion, improvements to existing technologies are necessary. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a fixation component and fixation bracket adapter that are easy to operate, readily usable by medical professionals, and whose fixation parts are well-suited to the instruments to be fixed, thus avoiding the problem of insecure fixation and possessing high practicality.

[0005] To achieve the above objectives, the present invention provides a fixing component for fixing and installing an instrument to be fixed, comprising:

[0006] A first fixing member having a first fitting cavity and a second fixing member having a second fitting cavity are provided. The first fixing member and the second fixing member are movably connected by an adjustment structure so that the first fitting cavity and the second fitting cavity together form a fixing fitting cavity for matching the device to be fixed.

[0007] The adjustment structure extends through both the first and second fixing members, and is used to adjust the relative distance between the first and second fixing members in the through direction, thereby adjusting the size of the fixing adapter cavity accordingly, so that the device to be fixed is clamped between the first and second fixing members. A first connecting part is provided at the end of the second fixing member away from the first fixing member, and the first connecting part is used to connect the fixing component to the medical device.

[0008] It should be noted that medical staff can clamp the instrument to be fixed by operating the adjustment structure. The operation is very simple and quick, which can save time. Moreover, the instrument to be fixed is fixed in the fixed adapter cavity, which can be more stable and less prone to slippage, thus improving reliability.

[0009] In some embodiments, the first fixing member and the second fixing member are respectively provided with corresponding guide structures for guiding when the first fixing member and the second fixing member move relative to each other.

[0010] The guide structure enables the movement trajectories of the first and second fixing components to be more targeted, preventing the fixing components from shifting during operation.

[0011] In some embodiments, the guide structure includes a guide hole disposed on the first fixing member and a guide post disposed on the second fixing member, the guide post and the guide hole being sized to match, and the extension direction of the guide post being parallel to the movement direction of the first fixing member.

[0012] Here, the cooperation of the guide post and the guide hole firstly determines the displacement direction of the first and second fixing parts, providing excellent guidance. In addition, when assembling the components at the beginning, the corresponding setting of the guide post and the guide hole also helps the operator to assemble more quickly.

[0013] In some embodiments, the adjusting structure includes a screw and a fixing nut. The fixing nut is located on the side of the first fixing member away from the second fixing member. The screw passes through the second fixing member, the first fixing member, and the fixing nut in sequence, and the external thread of the screw and the internal thread of the fixing nut are engaged, so that when the fixing nut rotates relative to the screw, the distance between the first fixing member and the second fixing member can be adjusted synchronously.

[0014] It should be noted that the distance between the first and second fixing parts is adjusted by setting a screw and a fixing nut. The operator can fix or remove the instrument to be fixed by simply turning the fixing nut, which is very convenient.

[0015] In some embodiments, an elastic element is provided between the first fixing member and the second fixing member. When the first fixing member moves away from the second fixing member, the elastic element simultaneously provides a rebound force, causing the first fixing member to move in the direction of the rebound force.

[0016] An elastic element is also provided here, which simplifies the operation process for operators. When tightening the fixing nut to widen the gap between the fixing parts, the elasticity of the elastic element makes tightening easier. The rebound force points in the direction of movement of the first fixing part, so that the first fixing part moves synchronously with the fixing nut, which is very reliable.

[0017] In some embodiments, a limiting portion is provided at the end of the screw near the fixing nut to prevent the fixing nut from falling off the screw.

[0018] The outer periphery of a portion of the screw is configured to be smooth, thus distinguishing the screw into a threaded portion and a smooth portion. When the fixing nut is located on the smooth portion, under the action of the elastic force of the elastic member, the fixing nut and the first fixing member are simultaneously displaced to the limit position in a direction away from the second fixing member.

[0019] It should be noted that the combination of the smooth surface and the threaded part can reduce the tightening time. Under the elastic force of the elastic element, the nut and the first fixing part will move directly to one side to the limit position, which makes it simpler and easier for the operator to remove the instrument to be fixed.

[0020] In some embodiments, the number of the first adapter cavity is at least two, and the number of the second adapter cavity matches the number of the first adapter cavity to form at least two fixed adapter cavities, each of the fixed adapter cavities passing through both the first fixing member and the second fixing member in a horizontal direction.

[0021] Furthermore, the extension directions of the fixed adapter cavities are parallel to each other or at a preset angle, thereby making the fixing component a multi-hole composite fixing groove to adapt to different instruments to be fixed.

[0022] In some embodiments, a rubber connector is further provided between the first fixing member and the second fixing member, the rubber connector matching the fixing adapter cavity, so that the instrument to be fixed is fixed by the rubber connector.

[0023] The rubber connector provided here can provide a certain degree of shock absorption, preventing various problems caused by collisions between the device to be fixed and the adapter cavity when they are fixed. In addition, the rubber connector has excellent wrapping properties, which can wrap around the outer periphery of the device to be fixed, making it less prone to displacement.

[0024] In some embodiments, the first adapter cavity and the second adapter cavity are respectively provided with protruding ends; when there is a first preset interval between the first fixing member and the second fixing member, the protruding end is embedded in the rubber connector, and the outer periphery of the rubber connector is in contact with the inner wall of the fixing adapter cavity; when there is a second preset interval between the first fixing member and the second fixing member, the rubber connector is isolated from at least a portion of the inner wall of the fixing adapter cavity through the protruding end.

[0025] It should be noted that the protruding end can help the rubber connector be removed from between the first and second fixing parts. When the two fixing parts are opened, the protruding end can lift the rubber connector, thereby reducing the friction between the rubber connector and the two fixing parts. This makes it less likely for the device to be fixed to vibrate when the rubber connector falls off.

[0026] In another aspect, the present invention also provides a fixing bracket adapter, comprising:

[0027] The aforementioned fixing component and at least one rocker arm, wherein the first connecting portion is configured as a ball joint end for realizing the rotation of the fixing component; one end of the rocker arm is connected to the ball joint end, and the other end is adapted to be fixed to a medical robot.

[0028] The rocker arm and the fixed component are connected in a cooperative manner, and the fixed component can be rotated through the ball joint end, which makes the device highly compatible and operable.

[0029] In some embodiments, the ball joint end includes a ball head disposed at the first connecting portion, two corresponding ball head pressure plates, and an adjustment knob. One end profile of the rocker arm is configured to be the same as the ball head profile. The two ball head pressure plates are connected by the adjustment knob. When the adjustment knob is rotated, the two ball head pressure plates are displaced relative to each other in a preset direction, and there is no gap between the ball head and the two ball head pressure plates, so that the ball head is pressed tightly and cannot rotate; or, a gap is created between the ball head and the two ball head pressure plates, so that the ball head can rotate relative to each other.

[0030] It should be noted that by adjusting the knob, the pressure plate on the ball head is controlled to tighten and loosen, allowing medical staff to adjust the position of the fixation component by operating the rocker arm. This enables them to control the orientation, position, and distance from the surgical site of the component, making the operation process very reliable.

[0031] Compared with the prior art, the fixing component and fixing bracket adapter provided by the present invention have the following advantages:

[0032] 1. The fixation component provided by the present invention can be connected to some medical devices through the first connecting part, with good compatibility and operability, and can be applied to more scenarios; in addition, through the ingenious setting of the adapter cavity on the two fixation members, the fixation component can present a multi-hole composite fixation groove form, which can be used with a variety of instruments.

[0033] 2. The fixing component provided by the present invention adjusts the relative distance between two fixing parts by setting screws and fixing nuts, thereby clamping the instrument between the fixing parts, making the operation process simple and easy to learn, and saving the operation time of medical staff.

[0034] 3. The fixing component provided by the present invention is provided with a guide structure, which makes the relative movement between the two fixing parts more targeted and less prone to deviation during movement.

[0035] 4. The fixing component provided by the present invention, through the combined use of elastic elements and smooth surfaces, enables the fixing nut and the first fixing element to quickly rebound to the limit position, reducing the tightening time and avoiding the vibration effect caused by continuous tightening of the fixing nut.

[0036] 5. The fixing component provided by the present invention has a rubber connector that can improve the wrapping and fixing effect of the device to be fixed, and when the two fixing parts are opened, the protruding end can also reduce the friction between the rubber connector and the fixing parts, making the installation and removal of the device to be fixed very reliable.

[0037] 6. The fixed bracket adapter provided by the present invention is provided with a ball joint end, and the rocker arm is connected to the ball joint end, so that the fixed component can achieve free rotation in three dimensions, thereby realizing a wide range of movement.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0056] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] In one embodiment, refer to the appendix to the specification. Figure 1 The present invention describes a fixing component that is easy to operate and whose fixing part is well adapted to the instrument to be fixed, thus avoiding the problem of insecure fixing. It has high adaptability and practicality.

[0058] Reference manual attached Figure 1 and Figure 2 The present invention provides a fixation component, comprising a first fixation member 1 having a first fitting cavity and a second fixation member 2 having a second fitting cavity. The first fixation member 1 and the second fixation member 2 are movably connected by an adjustment structure, such that the first fitting cavity and the second fitting cavity together form a fixation fitting cavity for matching the device to be fixed. The adjustment structure passes through both the first fixation member 1 and the second fixation member 2 to adjust the relative distance between the first fixation member 1 and the second fixation member 2 in the through direction, thereby adjusting the size of the fixation fitting cavity accordingly, so that the device to be fixed is clamped between the first fixation member 1 and the second fixation member 2. A first connecting part is provided at the end of the second fixation member 2 away from the first fixation member 1, and the first connecting part is used to connect the fixation component to a medical device.

[0059] Firstly, it is understandable that with the development of modern medical technology, many preoperative examinations and formal surgeries can be performed by surgical robots. As a result, some related instruments, such as puncture needles, ablation needles, or grinding tools for orthopedic surgery, need to be fixed to the corresponding surgical robot or operating table. Therefore, how to safely and quickly fix these related instruments is a problem that needs to be solved.

[0060] It should be noted that in this embodiment, medical staff can clamp the puncture needle or other medical devices by operating the adjustment structure. The operation is simple and quick, saving time. Moreover, the device is fixed in the fixed adapter cavity, which is more stable and less prone to slippage, thus improving reliability.

[0061] In addition, the first connecting part is used to fix the entire fixation assembly to the medical device, and it can be directly connected to the first connecting part or connected to the device after adding an extension arm to the first connecting part, so that the mobility and compatibility of the entire assembly are better.

[0062] The first and second adapter cavities have specific outlines, which can be found in the appendix of the instruction manual. Figure 2 Both edges are configured to have a certain curvature. This is just a preferred implementation of the adapter cavity and does not mean that it can only have this shape and outline.

[0063] In one embodiment, based on the above embodiment, the first fixing member 1 and the second fixing member 2 are respectively provided with corresponding guide structures for guiding when the first fixing member 1 and the second fixing member 2 generate relative movement.

[0064] The guide structure enables the movement trajectories of the first fixing member 1 and the second fixing member 2 to be more targeted, preventing the fixing members from deviating during operation.

[0065] In one embodiment, the guiding structure can be configured as a guide groove on the first fixing member 1 and a guide strip that is matched on the second fixing member 2. The guide groove and the guide strip are respectively disposed on the outer periphery of the first fixing member 1 and the second fixing member 2. The guide strip extends from the outer side wall of the second fixing member 2 toward the first fixing member 1, and plays a good guiding role when adjusting the position of the first fixing member 1 and the second fixing member 2. Furthermore, the guide strip can be inserted into the guide groove, which can also prevent the first fixing member 1 from circumferentially deflecting relative to the second fixing member 2.

[0066] In another embodiment, refer to the appendix to the specification. Figure 2 The guide structure includes a guide hole provided on the first fixing member 1 and a guide post 100 provided on the second fixing member 2. The guide post 100 and the guide hole are matched in size, and the extension direction of the guide post 100 is parallel to the movement direction of the first fixing member 1.

[0067] Here, the cooperation between the guide post 100 and the guide hole firstly determines the displacement direction of the first fixing member 1 and the second fixing member 2, which has a good guiding effect. In addition, when assembling the components at the beginning, since the guide post 100 and the guide hole are set in a corresponding manner, it can also help the operator to assemble more quickly.

[0068] It should be noted that the guide post 100 can also be set on the first fixing member 1 and the guide hole can be set on the second fixing member 2. The height of the guide post 100 and the depth of the guide hole can be changed according to the size of the other parts and actual needs.

[0069] In another embodiment, refer to the appendix to the specification. Figure 2 The adjustment structure includes a screw 3 and a fixing nut 4. The fixing nut 4 is located on the side of the first fixing member 1 away from the second fixing member 2. The screw 3 passes through the second fixing member 2, the first fixing member 1 and the fixing nut 4 in sequence, and the external thread of the screw 3 and the internal thread of the fixing nut 4 are engaged, so that when the fixing nut 4 rotates relative to the screw 3, the distance between the first fixing member 1 and the second fixing member 2 can be adjusted synchronously.

[0070] It should be noted that the distance between the first fixing member 1 and the second fixing member 2 is adjusted by setting the screw 3 and the fixing nut 4. The operator can fix or remove the medical device by turning the fixing nut 4, which is very convenient. This setting is very reliable and can ensure fixation and stability, and will not cause it to fall off and affect the operation.

[0071] In addition, the outline and shape of the fixing nut 4 can be appropriately changed, for example, adjusted to a more convenient gripping outline, and a seal can be set on its top to prevent part of the end of the screw 3 from being exposed to the outside world and rusting due to long-term contact with air. It can also prevent medical staff from being scratched by the end of the screw 3 during operation, resulting in hand injuries.

[0072] For a better option, please refer to the instruction manual. Figure 9 The number of adapter cavities on the first fixing member 1 and the second fixing member 2 can be increased, for example, by setting three or more. The two fixing members can be set into a disc shape, and the adapter cavities are parallel to the radial direction of the disc. As shown in the figure, adapter cavities of different sizes and shapes can be generated. Then the first fixing member 1 and the second fixing member 2 can form a composite connecting tool, which can fix different medical devices, such as puncture needles and biopsy needles. When fixing, the puncture needle is fixed by passing through the two discs, which can greatly ensure the firmness and does not require the replacement of parts, making it more convenient and faster. Alternatively, the adapter cavities can be distributed in an alternating manner relative to the discs, so that the first fixing member 1 and the second fixing member 2 form several through holes to form a multi-hole composite fixing groove, so that some medical devices, such as the above-mentioned puncture needles, pass through the corresponding through holes and then tighten the fixing nut 4 for fixation.

[0073] Alternatively, the adjustment structure can be configured to accommodate a telescopic rod and a tension spring. The two ends of the telescopic rod are fixed between the first fixing member 1 and the second fixing member 2. The tension spring can be installed inside the hollow structure of the telescopic rod. In its natural state, due to the characteristics of the tension spring, there is no gap between the first fixing member 1 and the second fixing member 2. When it is necessary to clamp and fix the instrument, simply pull either fixing member. The tension spring will then unfold in the direction of the pulling force. At this time, the connecting part of the instrument can be placed into the fixing adapter cavity. After adjusting the position of the instrument, the operator can release the tension spring, and the tension spring will return to its initial state, thus clamping the first fixing member 1 and the second fixing member 2.

[0074] Even better, a limiting part is provided at the end of the screw 3 near the fixing nut 4, the limiting part is used to prevent the fixing nut 4 from falling off the screw 3.

[0075] Reference manual attached Figure 5 The limiting part here is set as a limiting round head 41, but it can also be set to other shapes, which will not be listed here. The limiting round head 41 can be integrally formed with the screw 3, or connected to the screw 3 by threads, or snap-fit ​​connection; in addition, the size of the limiting round head 41 can be designed to be larger than the threaded hole size of the fixing nut 4, so that it can always abut against the top wall of the fixing nut 4. Alternatively, a stepped hole can be set in the fixing nut 4, so that the limiting round head 41 can be snapped into the stepped hole, which can also play a limiting role. Moreover, this can also increase the effective displacement length of the fixing part.

[0076] In addition, based on the above embodiments, a shock-absorbing component can be provided between the limiting part and the fixing nut 4 to prevent collision or wear between the fixing nut 4 and the limiting part.

[0077] It should be noted that the shock absorber can be a shock-absorbing sponge or a silicone pad, soft rubber pad or similar material, which will not be listed here. The distribution and setting of the shock absorber can be directly sleeved on the outer periphery of the screw 3 between the limiting part and the fixing nut 4, or it can be fixed on the side wall of the limiting part near the fixing nut 4.

[0078] In one embodiment, refer to the specification. Figures 3 to 5 An elastic element is provided between the first fixing member 1 and the second fixing member 2. When the first fixing member 1 moves away from the second fixing member 2, the elastic element provides a rebound force simultaneously, causing the first fixing member 1 to move in the direction of the rebound force.

[0079] An elastic element is also provided here, which simplifies the operation process for operators. When tightening the fixing nut 4 to widen the gap between the fixing parts, the elasticity of the elastic element makes tightening easier. The rebound force points in the direction of movement of the first fixing part 1, so that the first fixing part 1 moves synchronously with the fixing nut 4, which is very reliable.

[0080] In one embodiment, refer to the appendix to the specification. Figure 4 The elastic element can be set as a spring 5 or an elastic multi-layer corrugated washer, which has better waterproof performance and can be used in humid environments, avoiding the problem of frequent maintenance and replacement of the elastic element.

[0081] In this embodiment, the spring 5 is sleeved on the outer periphery of the screw 3, and its two ends abut against the spring receiving grooves opened on the first fixing member 1 and the second fixing member 2, which can prevent the spring 5 from shifting during the operation of the assembly.

[0082] In one embodiment, the outer periphery of a portion of the screw 3 is configured as a smooth surface, so that the screw 3 is distinguished into a threaded portion and a smooth portion. When the fixing nut 4 is located in the smooth portion, under the action of the elastic force of the elastic element, the fixing nut 4 and the first fixing member 1 are simultaneously displaced to the limit position in a direction away from the second fixing member 2.

[0083] It should be noted that the matching of the smooth surface and the threaded part can reduce the turning time. Under the elastic force of the elastic element, the nut and the first fixing part 1 will move directly to one side to the limit position, which makes it simpler and easier for the operator to remove the instrument.

[0084] In addition, the smooth part can be set at the end of the screw 3, which makes the processing more convenient. Apart from the smooth part, the screw 3 is a continuous threaded part, which will not affect the normal use of the screw 3.

[0085] Furthermore, it can be used in conjunction with the limiting part and shock absorber in the above embodiments, so that the fixing nut 4 will not fall off when the smooth surface is subjected to spring force, and vibration problems can also be avoided.

[0086] To prevent the fixing nut 4 from falling off, an anti-loosening threaded part can be provided at the top of the screw 3, so that the two ends of the smooth surface are restricted by different threaded parts. When the fixing nut 4 moves in the direction of falling off, it cannot continue to slide due to the restriction of the anti-loosening threaded part at the top, and naturally cannot fall off the screw 3.

[0087] In one embodiment, based on the above embodiments, such as Figure 4 As shown, a knob 31 is provided at the end of the screw 3 away from the fixing nut 4, and a corresponding housing 300 with an opening is provided so that the knob 31 can be operated through the opening; one side of the housing 300 is connected to the first connecting part, and the other side abuts against the second fixing member 2, wherein the second fixing member 2 is provided with a limiting groove corresponding to the housing 300, which is used to limit the circumferential rotation of the second fixing member 2, and the knob 31 is used to drive the screw 3 to adjust the distance between the end of the housing 300 and the second fixing member 2 to adjust the limiting state of the second fixing member 2 relative to the housing 300.

[0088] It is understandable that the screw 3 passes through the second fixing member 2 for fixation. In this embodiment, this setting can prevent the second fixing member 2 from rotating relative to the screw 3 in some special cases. For example, if medical staff do not tighten the fixing nut 4 when fixing the component, the second fixing member 2 will gradually loosen due to the vibration of the machine. If this limiting groove and the limiting structure of the outer shell 300 are not set, the second fixing member 2 will inevitably rotate or shake, resulting in the instability of the fixing component, which will seriously endanger the health of the patient.

[0089] This embodiment solves the above problems and is also very flexible in operation. After aligning the limiting groove on the second fixing member 2 with the outer shell 300, the two are pressed together and the knob 31 is turned to fix them together by the screw 3. In this case, the second fixing member 2 is restricted in displacement and is in a limited state. When it is necessary to remove the second fixing member 2, the knob 31 is turned in the opposite direction. A certain distance will be generated between the second fixing member 2 and the outer shell 300. When the distance is greater than the depth of the limiting groove, the second fixing member 2 can rotate relative to the screw 3 and thus be removed.

[0090] In addition, since the first fixing member 1 does not have such a limiting groove structure, this setting can also be used to strengthen the distinction between the first fixing member 1 and the second fixing member 2, making assembly more convenient.

[0091] However, it is also important to note that, such as Figure 11 As shown, the second fixing member 2 and the outer shell 300 can also be directly fixed by welding or other similar methods, eliminating the structural design of the limiting groove, toggle 31, etc. in the above embodiment. That is, the outer shell 300, the second fixing member 2, and the screw 3 are all fixed together. The gap between the first fixing member 1 and the second fixing member 2 is adjusted by tightening the fixing nut 4, ensuring the stability and reliability of the device. At the same time, it can be used in combination with the above-mentioned multi-hole composite fixing groove form. While ensuring the safety of the device, it also realizes the wide application of the device, and most surgical work can be completed without frequent replacement of the fixing head.

[0092] In another embodiment, in the case of the above embodiment, it is also feasible to remove the outer shell 300 and let one end of the screw 3 extend directly out of the first connecting part. Since this application has already described the connection method and the movement method at this position in detail, this embodiment will not be described in detail here. If only the connection method in this application is simply adjusted or simple technology is superimposed, it should also be included in the protection scope of this application.

[0093] In one embodiment, refer to the appendix to the specification. Figure 2A rubber connector 8 is also provided between the first fixing member 1 and the second fixing member 2. The rubber connector 8 matches the fixing adapter cavity so that the puncture needle is fixed through the rubber connector 8.

[0094] The rubber connector 8 provided here can provide a certain shock absorption effect, avoiding various problems caused by collisions between the medical devices when they are fixed to the fixed adapter cavity. In addition, the rubber connector 8 has excellent wrapping properties, which can wrap around the outer periphery of the connection part of the device, making it less prone to displacement.

[0095] The rubber connector 8 is provided with a receiving groove, which allows the instrument to be fixed to be placed from the opening of the receiving groove. For example, the puncture needle is well-suited to it. Due to the elasticity of the rubber connector 8 itself, when the first fixing member 1 and the second fixing member 2 fix the puncture needle, the opening of the receiving groove is simultaneously pressed and closed.

[0096] The inner walls of the first and second adapter cavities can also be provided with corresponding clamping ends, with the clamping ends corresponding to the positions of the openings, so as to achieve a better clamping effect.

[0097] Similarly, some plastic connectors can be used to fix the instrument. Depending on the different connectors, the contours and sizes of the first and second adapter cavities can also be adjusted accordingly, making the examination or treatment process more targeted.

[0098] Please refer to the instruction manual. Figure 6 , Figure 7 ,in Figure 6 Compared to the size of the fixed adapter cavity in the middle Figure 7 The size of the fixed adapter cavity in the middle is smaller, then Figure 7 The fixation components can be adapted to some larger diameter puncture needles or grinding tools, thus enabling their application in tumor puncture treatment robots or orthopedic surgical robots; Figure 6 The fixation components can be adapted to relatively narrow instruments, allowing users to set the appropriate size according to the instruments they need to fix, such as ablation needles or biopsy sampling needles, so that they can be used for tumor biopsy sampling. In specific operation and use, various styles and different fixation adapter cavity sizes of fixation components are directly produced to match different instruments.

[0099] It should also be noted that the outline and cross-sectional shape of the first fastener 1 or the second fastener 2 can be changed accordingly; please refer to the appendix to the instruction manual. Figure 8 The figure shows one embodiment of the first fastener 1, which is beneficial to the overall lightweighting of the component. The second fastener 2 is also set accordingly, which will not be described in detail here.

[0100] In another embodiment, refer to the appendix to the specification. Figure 4 The first adapter cavity and the second adapter cavity are respectively provided with a protruding end 10; when there is a first preset interval between the first fixing member 1 and the second fixing member 2, the protruding end 10 is embedded in the rubber connector 8, and the outer periphery of the rubber connector 8 is in contact with the inner wall of the fixing adapter cavity; when there is a second preset interval between the first fixing member 1 and the second fixing member 2, the rubber connector 8 is isolated from at least part of the inner wall of the fixing adapter cavity through the protruding end 10.

[0101] It should be noted that the protruding end 10 can help the rubber connector 8 to be removed from between the first fixing member 1 and the second fixing member 2. When the two fixing members are opened, the protruding end 10 can lift the rubber connector 8, thereby reducing the friction between the rubber connector 8 and the two fixing members, so that the puncture needle is less likely to vibrate when removing the rubber connector 8.

[0102] The first and second preset intervals need to be determined based on the dimensions of the relevant components in the assembly. It can be understood that when the interval between the first fixing member 1 and the second fixing member 2 is relatively small, the protruding end 10 can be embedded in the rubber. This interval can be called the first preset interval. At the same time, the rubber connector 8 and the fixing adapter cavity will fit very tightly. It should be noted that due to the different contour designs of the fixing adapter cavity, the fit between the two can be completely fitted or partially fitted. Similarly, when the interval between the first fixing member 1 and the second fixing member 2 is large, the protruding end 10 pushes up the rubber connector 8, so that there is a gap between the two, which reduces friction. This interval is called the second preset interval.

[0103] More preferably, a number of protrusions or grooves are provided on the inner circumference of the rubber connector 8. When fixing the puncture needle or other instruments, the protrusions or grooves fit against the outer circumference of the puncture needle. When disassembling the puncture needle, the protrusions or grooves will separate the outer wall of the puncture needle from the inner wall of the rubber connector 8, making it easier to remove the puncture needle.

[0104] It should be noted that the above embodiments can be used in any combination, and the first fixing member 1 and the second fixing member 2 can be connected by a hinge on one side. Please refer to the appendix of the instruction manual for details. Figure 10 The screw 3, the first fixing member 1, and the second fixing member 2 are connected by a screw-tightening component. When the screw-tightening component is turned, the first fixing member can be displaced in a counterclockwise or clockwise direction through the hinge, which can open the adapter cavity between the two fixing members to insert or remove the medical device, or make the two fixing members clamp the medical device to play a fixing role.

[0105] In one embodiment, refer to the appendix to the specification. Figure 1According to another aspect of the present invention, the present invention further provides a fixing bracket adapter, including the above-described fixing component and at least one rocker arm 9, wherein a first connecting portion is configured as a ball joint end for realizing the rotation of the fixing component; one end of the rocker arm 9 is connected to the ball joint end, and the other end is adapted to be fixed to a medical robot.

[0106] The rocker arm 9 is connected to the fixed component, and the fixed component can be rotated through the ball joint end, which makes the device highly compatible and operable.

[0107] It should be noted that there can be one or more rocker arms 9. Multiple rocker arms 9 can be connected end to end in sequence to form a continuous multi-directional rocker arm structure, and the two ends are respectively connected to the ball joint end and the corresponding puncture device.

[0108] In one embodiment, based on the above embodiment, the ball joint end includes a ball head 61 fixed to the first connecting part, two corresponding ball head pressure plates 6, and an adjustment knob 7. One end profile of the rocker arm 9 is configured to be the same as the profile of the ball head 61. The two ball head pressure plates 6 are connected by the adjustment knob 7. When the adjustment knob 7 is rotated, the two ball head pressure plates 6 are displaced relative to each other in a preset direction, and there is no gap between the ball head 61 and the two ball head pressure plates 6, so that the ball head 61 is pressed and cannot rotate; or, a gap is created between the ball head 61 and the two ball head pressure plates 6, so that the ball head 61 can rotate relative to each other.

[0109] It should be noted that by adjusting the knob 7, the pressure plate 6 on the ball head 61 is controlled to tighten and loosen, so that medical staff can adjust the position of the fixation component by operating the rocker arm 9. This allows them to control the orientation, position, and distance from the surgical site of the fixation component, thus making the puncture process very reliable.

[0110] The adjusting knob 7 can be set in conjunction with the fastening nut. An adjusting rod is fixed on the adjusting knob 7, and the adjusting rod passes through the two ball head pressure plates 6 and is then fixed with the fastening nut. When the adjusting knob 7 is rotated, the tension of the ball head pressure plate 6 relative to the ball head 61 can be controlled.

[0111] In another embodiment, refer to the appendix to the specification. Figure 1 The two ball head pressure plates 6 are each provided with two hemispherical grooves, and the two corresponding hemispherical grooves form a ball head receiving groove for matching with the ball head 61.

[0112] Each ball head 61 can rotate 360 ​​degrees, and the combination of two ball heads 61 can make the medical device fixed by the fixing component face any direction. Medical staff can use this setting to complete the accurate positioning before operation. After positioning, the ball head pressure plate 6 is fixed by adjusting the knob 7, which is very convenient and safer.

[0113] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
