[0034] The core of the present application is to provide a handle support device for fixing and installing multiple handles used on interventional medical devices, and the relative positions between the multiple handles can be adjusted, thereby solving the problem that the existing handle bracket cannot adjust the relative positions between the handles.
[0035] The handle support device provided in the present application also has the function of adjusting the inclination angle of the handle to meet the requirements for the handle angle during clinical or testing processes.
[0036] The handle support device of the present application is applicable to various interventional medical device products, including, for example, implant delivery devices, surgical instruments, endoscopes, etc., without specific limitation.
[0037] It should be understood that the interventional medical device products mentioned in this application need to use multiple handles at the same time, such as two or more handles, and realize multiple functions through different handles, such as bending control, movement, rotation or other related functions. In practice, the handle support device of this application can be used in various appropriate occasions to fix and install the handle.
[0038] In order to enable those skilled in the art to better understand the technical solution provided by the present application, the handle support device provided by the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] Please refer to Figures 1 to 7 A handle support device provided in an embodiment of the present application includes a base 100 and at least three fixed brackets. The at least three fixed brackets include a fixed bracket 200 at the farthest end, at least one fixed bracket 300 in the middle, and a fixed bracket 400 at the closest end. Each fixed bracket is used to install a handle on an interventional medical device. All fixed brackets are stacked in sequence and arranged in parallel on the base 100. In any two adjacent stacked fixed brackets, the upper fixed bracket can be slidably connected to the lower fixed bracket. The sliding directions of each fixed bracket are parallel to each other, and the sliding direction is basically parallel to the length direction of the interventional medical device. When any slidable fixed bracket slides to a certain position, it can remain self-locking and will not move easily, thereby ensuring stability.
[0040] Take three fixed brackets as an example, the three fixed brackets are stacked in sequence and arranged in parallel on the base 100. Among them, the farthest fixed bracket 200 is rotatably connected to the base 100, so that it can rotate in a vertical plane relative to the base 100, and the farthest fixed bracket 200 cannot be moved; the middle fixed bracket 300 is slidably connected to the farthest fixed bracket 200, and the middle fixed bracket 300 cannot be rotated but can only be moved; similarly, the closest fixed bracket 400 is slidably connected to the middle fixed bracket 300, and the closest fixed bracket 400 cannot be rotated but can be moved. The three fixed brackets are respectively used to install and fix a handle, that is, only one handle can be placed on each fixed bracket; each time in use, a handle can be placed on each fixed bracket, or on some of the fixed brackets.
[0041] It should be understood that the farthest fixing bracket 200 is usually located closest to the catheter connected to the handle, the most proximal fixing bracket 400 is located farthest from the catheter, and one or more intermediate fixing brackets 300 are located between the farthest fixing bracket 200 and the most proximal fixing bracket 400.
[0042] In various embodiments of the present application, the number of the fixing brackets is three or more. When there are three fixing brackets, only one fixing bracket 300 is arranged in the middle; when there are more than three fixing brackets, two or more fixing brackets 300 are arranged in the middle. In this embodiment, there are three fixing brackets, which can basically meet the use requirements of various commonly used interventional medical device products.
[0043] When using the handle support device of this embodiment, if the handle needs to be moved, it is only necessary to move the fixed bracket supporting the handle to change the relative position of the handles, and some of the handles can be kept relatively fixed but can move relative to other handles.
[0044] For example, the middle fixed bracket 300 is fixed and the closest fixed bracket 400 moves. At this time, the farthest fixed bracket 200 and the middle fixed bracket 300 remain relatively fixed, and the closest fixed bracket 400 can move relative to the other two fixed brackets, which realizes the function of keeping some handles relatively fixed and some handles relatively moving; or, the closest fixed bracket 400 is fixed and the middle fixed bracket 300 moves. At this time, the closest fixed bracket 400 and the middle fixed bracket 300 remain relatively fixed as a whole, so that the closest fixed bracket The bracket 400 and the middle fixed bracket 300 can be moved as a whole relative to the farthest fixed bracket 200, and some handles can remain relatively fixed, while some handles can move relatively. Alternatively, the nearest fixed bracket 400 and the middle fixed bracket 300 can both be moved. At this time, the nearest fixed bracket 400 can move relative to the middle fixed bracket 300 and the farthest fixed bracket 200, and the middle fixed bracket 300 can move relative to the nearest fixed bracket 400 and the farthest fixed bracket 200. In this way, the relative position of each handle can be changed.
[0045] Therefore, the handle support device of this embodiment can flexibly adjust the relative positions of the handles to better meet the requirements of the relative position relationship between the catheters in clinical or testing processes.
[0046] Compared with the prior art, the handle support device of this embodiment can install and fix multiple handles through multiple fixed brackets, and the position of the handle can be adjusted through any slidable fixed bracket, and the handle position can be kept stable through self-locking, and the relative position of each handle can be adjusted at any time, which not only completely liberates the user's hands and improves work efficiency, but also can accurately adjust the relative position of the handles, and can more stably support the fixed handles, so that the effectiveness of the handle operation is better. Especially for clinical surgery, the surgical efficiency is higher and the surgical risk is lower.
[0047] Further, the handle support device also includes an angle adjustment mechanism 101 disposed on the base 100, and the angle adjustment mechanism 101 is connected to a fixed bracket 200 at the farthest end. The function of the angle adjustment mechanism 101 is to drive the fixed bracket 200 at the farthest end to rotate around the horizontal axis 201 in the vertical plane, thereby adjusting the angle between the fixed bracket 200 at the farthest end and the horizontal plane, that is, the inclination angle of the fixed bracket 200 at the farthest end, and changing the inclination angle of the handle relative to the horizontal plane. During clinical surgery, when the angle between the fixed bracket 200 at the farthest end and the horizontal plane is determined, the angle between the entire handle and the operating table plane is also determined. Preferably, the angle between the fixed bracket 200 at the farthest end and the horizontal plane is 15°-45°. With such a configuration, the present application can also adjust the inclination angle of each fixed bracket at any time through the angle adjustment mechanism 101, and then adjust the inclination angle of the handle, which is conducive to quickly finding an optimal inclination angle that is conducive to catheter access before surgery, making the access more accurate, more convenient and safer.
[0048] It should be recognized that there are many ways to implement the angle adjustment mechanism 101. In addition to the screw and nut adjustment mechanism described in the figure, there are other commonly used mechanical motion mechanisms, such as: gear racks, electric push rods, linear motors, cam sliders, connecting rod mechanisms, etc., which can ultimately convert rotational motion or linear motion into swinging. Therefore, in addition to the movement modes of the screw and nut listed in the embodiments of the present application, technicians in the relevant field can find other alternative ways to achieve the functions / achieve the above-mentioned effects recorded in the angle adjustment mechanism 101 of the present application based on the records of the specification of the present application, and not just the solutions disclosed in the embodiments of the present application.
[0049] Furthermore, considering the many advantages of screw and nut adjustment, the angle adjustment mechanism 101 preferably adopts a screw and nut adjustment mechanism.
[0050] according to Figures 1 to 4In the described specific embodiment, the angle adjustment mechanism 101 includes an angle adjustment screw 1011, an angle adjustment nut 1012 and a support shaft 1013; the angle adjustment screw 1011 is extended in the horizontal direction and rotatably arranged on the base 100; the angle adjustment nut 1012 is slidably sleeved on the angle adjustment screw 1011; one end of the support shaft 1013 is rotatably connected to the angle adjustment nut 1012, and the other end of the support shaft 1013 is rotatably connected to a fixed bracket 200 at the farthest end. The angle adjustment screw 1011 can only rotate, and by rotating the angle adjustment screw 101, the angle adjustment nut 1012 is driven to slide along the angle adjustment screw 1011, and then the angle adjustment nut 1012 drives the support shaft 1013 to swing up and down to lift or lower the far-end fixed bracket 200. In this way, the angle adjustment nut 1012 is driven by the angle adjustment screw 1011 to reciprocate on the angle adjustment screw 1011, and drives the support shaft 1013 to swing, so that the remote fixed bracket 200 rotates around the horizontal rotating shaft 201 to achieve the angle change of the entire fixed bracket.
[0051] Continue to refer Figure 3 and Figure 4 , an axial hole 102 may be optionally provided on the base 100, and a rotating shaft 201 may be provided on one side of a fixed bracket 200 at the farthest end, and the rotating shaft 201 may be assembled in the axial hole 102 to realize the rotation connection between the base 100 and the fixed bracket 200 at the farthest end, and provide a fulcrum for the rotation of the fixed bracket 200 at the farthest end. In order to better guide the movement of the angle adjustment nut 1012, a slideway 103 may be optionally provided on the base 100, and the angle adjustment nut 1012 is limited at the slideway 103 of the base 100 and is used to slide along the slideway 103, thereby driving the support shaft 1013 to swing in the vertical plane.
[0052] The base 100 serves as the supporting part of the entire handle supporting device, and its structure and shape are not particularly limited, as long as the base 100 can be stably placed on a horizontal plane.
[0053] In some application scenarios, the base 100 is directly placed on the operating table, so that multiple handles used for interventional medical devices can be installed and fixed during clinical surgery through the handle support device.
[0054] In other application scenarios, the base 100 is directly placed on a test bench or a laboratory bench, and the handle support device is used to install and fix multiple handles used by the interventional medical device during the test process.
[0055] Optionally, in one embodiment, the base 100 includes a flat plate 110 and a plurality of legs 120 fixed to the bottom of the flat plate 110, and the plurality of legs 120 are distributed in a polygonal shape, thereby placing the entire handle support device firmly on a horizontal plane. Based on this, the number of legs 120 is preferably three or four. The flat plate 110 is used to install a fixed bracket, an angle adjustment mechanism 101, etc. This base 100 has a simple structure, is easy to manufacture, and is easy to install and use. However, those skilled in the art should understand that in other embodiments, the base 100 can be directly placed firmly on a horizontal plane in other suitable structural shapes, such as columns of various shapes, frames of various shapes, etc., and the legs 120 can be omitted.
[0056] Next, the structure and movement method of each fixed bracket are further explained.
[0057] In some embodiments, the corresponding fixed bracket is moved by manually operating the fixed bracket.
[0058] In other embodiments, the fixed bracket is automatically driven to move by a mechanical structure.
[0059] In order to accurately adjust the position of each fixed bracket, in a specific embodiment, the fixed bracket is driven to move by a linear motion mechanism, and the self-locking function of the fixed bracket is realized at the same time.
[0060] In various embodiments disclosed in the present application, any two adjacent stacked fixing brackets are preferably kept in the current position by the self-locking function between the screw and nut, but it is not limited to this.
[0061] In this embodiment, the handle support device also includes at least two sets of linear motion mechanisms 500, and any slidable fixed bracket is driven to slide by a corresponding set of linear motion mechanisms 500, and each set of linear motion mechanisms 500 has a self-locking function, so that the corresponding fixed bracket remains self-locked when it slides to a certain position. For example, there are three fixed brackets, and the middle fixed bracket 300 is controlled by a set of linear motion mechanisms 500 to move and self-lock, and the closest fixed bracket 400 is controlled by another set of linear motion mechanisms 500 to move and self-lock; when the number of fixed brackets is more than three, movement and self-locking are achieved in a similar manner, that is, each of the middle fixed brackets 300 is controlled by a corresponding set of linear motion mechanisms 500 to move and self-lock.
[0062] Those skilled in the art should know that there are many ways to implement the linear motion mechanism 500, including but not limited to the following: a rack and pinion mechanism, a screw-nut mechanism, an electric push rod, a linear motor, etc.
[0063] Preferably, each set of linear motion mechanism 500 is a screw-nut mechanism, so that each slidable fixed bracket is controlled to slide by a corresponding set of screw-nut mechanisms. The screw-nut mechanism also has a certain self-locking performance, which can keep the position of the fixed bracket stable and not easily affected by external interference. When there is a need for relative movement between the handles, each handle can move relative to each other by rotating and moving the adjusting screw.
[0064] In more detail, each set of linear motion mechanism 500 includes a movable adjustment screw 501 and a movable adjustment nut 502; the movable adjustment screw 501 is rotatably arranged on a corresponding fixed bracket; the movable adjustment nut 502 is slidably mounted on the movable adjustment screw 501; any slidable fixed bracket is fixedly connected to a corresponding movable adjustment nut 502. The movable adjustment screw 501 can only rotate, and by rotating the movable adjustment screw 501, the movable adjustment nut 502 is driven to slide along the movable adjustment screw 501, and then the movable adjustment nut 502 drives a corresponding fixed bracket to move, thereby changing the position of the handle on the sliding fixed bracket.
[0065] Figure 4 and Figure 6 In the exemplary embodiment described, a set of linear motion mechanism 500 is arranged between the most distal fixed bracket 200 and the middle fixed bracket 300 stacked adjacent thereto, wherein a movable adjustment screw 501 is rotatably arranged on the most distal fixed bracket 200, and a movable adjustment nut 502 is fixedly connected to the middle fixed bracket 300. Optionally, a movable adjustment nut 502 is directly arranged at the bottom of the middle fixed bracket 300. By rotating the movable adjustment screw 501, the movable adjustment nut 502 is driven to slide along the movable adjustment screw 501, and then the movable adjustment nut 5022 drives the middle fixed bracket 300 to move, so that the handle placed on the middle fixed bracket 300 can change its position. Optionally, the movable adjustment nut 502 at the bottom of the middle fixed bracket 300 is limited to the slideway 202 on the most distal fixed bracket 200 and slides along the slideway 202.
[0066] Continue to refer Figure 4 , and combined with Figure 5, the farthest fixed bracket 200 is generally an L-shaped structure, the horizontal frame of which is used to stack the middle fixed bracket 300 and other related structures, and the vertical frame of which is used to directly install the fixed handle. As in the present embodiment, the top of the vertical frame on the farthest fixed bracket 200 is provided with a support groove 203, and the support groove 203 is a circumferentially open structure, and the two ends of the support groove 203 along the sliding direction of the fixed bracket are open. In this way, the farthest fixed bracket 200 supports the placement of the handle through the support groove 203. In the farthest fixed bracket 200, the support groove 203 has a variety of shapes, not only limited to arc-shaped grooves, but also U-shaped grooves, V-shaped grooves or grooves of other shapes can be used.
[0067] In order to fix the handle, a fixing bolt 204 is also provided on the vertical frame in the farthest fixed bracket 200 for fixing or unlocking a single handle. When the handle is placed at the support groove 203 on the farthest fixed bracket 200, the fixing bolt 204 can be tightened or loosened to stably fix the handle or remove it smoothly.
[0068] In order to more stably fix the handle on the support groove 203 on the farthest fixed bracket 200, preferably, a limit block 205 is set on the inner wall of the support groove 203, and the limit block 205 can cooperate with the groove or other forms of structure on the handle to further limit the relative sliding of the handle and the support groove 203.
[0069] also, Figure 6 and Figure 7 In the exemplary embodiment described, another set of linear motion mechanism 500 is arranged between a middle fixed bracket 300 and a nearest fixed bracket 400 of the adjacent stack, wherein a movable adjustment screw 501 is rotatably arranged on a middle fixed bracket 300, and a movable adjustment nut 502 is fixedly connected to the nearest fixed bracket 400. Optionally, a movable adjustment nut 502 is directly arranged at the bottom of the nearest fixed bracket 400. By rotating the movable adjustment screw 501, the movable adjustment nut 502 is driven to slide along the movable adjustment screw 501, and then the nearest fixed bracket 400 is driven to move by the movable adjustment nut 502, so that the handle placed on the nearest fixed bracket 40 can change its position. Optionally, the movable adjustment nut 502 is limited to the slideway 301 on the middle fixed bracket 300 and slides along the slideway 301.
[0070] Continue to refer Figure 6The middle fixed bracket 300 is also an L-shaped structure, and its horizontal frame is used to stack another middle fixed bracket 300 or the nearest fixed bracket 400, and its vertical frame is used to directly install the fixed handle. Similar to the farthest fixed bracket 200, the top of the vertical frame on the middle fixed bracket 300 is provided with a support groove 302, and the structure and function of the support groove 302 are basically the same as the structure and function of the support groove 203 on the farthest fixed bracket 200, and will not be described in detail here.
[0071] Furthermore, in order to fix the handle, a fixing bolt 303 is also provided on the vertical frame of the middle fixing bracket 300 for fixing or unlocking a single handle. When the handle is placed on the support groove 302, the handle can be stably fixed or removed smoothly by tightening or loosening the fixing bolt 303. Preferably, a limit block 304 is provided on the inner wall of the support groove 302. The limit block 304 can cooperate with a groove or other structure on the handle to limit the relative sliding of the handle and the support groove 302, so that the handle is more stably fixed at the support groove 302.
[0072] For the nearest fixed bracket 400, its structure is different from the structure of the aforementioned fixed bracket, and it no longer has a horizontal frame, and only needs to retain the vertical frame. Preferably, the movable adjustment nut 502 connected to the nearest fixed bracket 400 can be directly integrally formed with the fixed bracket.
[0073] Figure 7 In the exemplary embodiment of the nearest fixed bracket 400 described, only one vertical bracket is provided as the fixed bracket, and a support groove 401 is provided at the top end of the vertical bracket, and a movable adjustment nut 502 is provided at the bottom end.
[0074] Optionally, in the nearest fixing bracket 400, a fixing bolt 402 is further provided at the top of the vertical frame for fixing or unlocking a single handle. In addition, in order to fix the handle more stably at the support groove 401, a limiting block 403 is preferably provided on the inner wall of the support groove 401, and the limiting block 403 can cooperate with the groove or other forms of structure on the handle, thereby limiting the relative sliding of the handle and the support groove 401.
[0075] It should be supplemented that, in the various embodiments of the present application, the structures and functions of the support grooves, fixing bolts and limit blocks on each fixing bracket are basically the same and will not be repeated.
[0076] Finally, it should be noted that in the methods disclosed in the various embodiments above, the handle is locked and unlocked by a fixing bolt. However, it should be recognized that other commonly used fastening connection methods may also be applicable to the present application, such as clamping, snapping, magnetic attraction, etc., which can be adaptively adjusted according to needs and are not limited to the locking method of the fixing bolt disclosed in this embodiment.
[0077] In summary, the beneficial effects of the handle support device provided in the embodiment of the present application are:
[0078] The handle support device described above includes: a base 100, an angle adjustment mechanism 101 and at least three fixed brackets; each of the fixed brackets is used to fix a handle on an interventional medical device; all the fixed brackets are stacked in sequence and arranged in parallel on the base 100; in any two adjacent stacked fixed brackets, the upper fixed bracket can be slidably connected to the lower fixed bracket; any one of the slidable fixed brackets can remain self-locked when sliding to a certain position; the farthest fixed bracket 200 is rotatably connected to the base 100; the angle adjustment mechanism 101 is arranged on the base 100 and connected to the farthest fixed bracket 200, so as to drive the farthest fixed bracket 200 to rotate around the horizontal rotation axis 201 in the vertical plane, thereby adjusting the angle between the farthest fixed bracket 200 and the horizontal plane.
[0079] With such configuration, the handle support device of the present application can adjust the position of the handle through any slidable fixed bracket, and maintain the stability of the handle position through self-locking, while being able to flexibly adjust the relative position between each handle, which can not only change the relative position between each handle, but also make multiple handles relatively fixed but move relative to other handles, which not only completely liberates the hands of the user and improves work efficiency, but also can more accurately adjust the relative position between the handles, and more stably support the fixed handles, better ensure the effectiveness of the operation, especially for clinical surgery, the operation efficiency is higher and the operation risk is lower. On the other hand, the inclination angle of each fixed bracket can be adjusted at any time through the angle adjustment mechanism 101, and then the inclination angle of the handle can be adjusted, which is conducive to finding the optimal inclination angle when the catheter enters the route, making the route more accurate, more convenient and safer.
