For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The utility model aims to provide a handle bracket to solve the problem that the existing bracket cannot adjust the relative positions of the handles.

[0030] The handle bracket provided by the utility model is applicable to medical device products, and can be applicable to various medical device products, such as delivery systems, treatment devices, auxiliary devices, surgical instruments, etc., without limitation to specific types.

[0031] The medical device product involved in the utility model has multiple handles, such as two handles or more handles, which can provide various functions, such as bending control, delivery, release, recovery, etc. This kind of medical device product is mostly a catheter device, at least part of the distal end of the catheter will enter the body, and the handle at the proximal end of the catheter is located outside the body.

[0032] The handle bracket provided by the utility model is used to support multiple handles of the medical device product used simultaneously, and can be used during surgery or testing or in other occasions.

[0033] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Specifically, Figures 1 to 4 As shown, a handle bracket provided by the utility model comprises a fixed frame 1 and a plurality of movable frames 2 which are slidably connected in sequence. That is, a first movable frame 210 among the plurality of movable frames 2 is slidably arranged on the fixed frame 1, and the plurality of movable frames 2 are slidably stacked in sequence. In more detail, the first movable frame 210 is stacked on the fixed frame 1 in a direction perpendicular to the sliding plane of the movable frame 2, and accordingly, the plurality of movable frames 2 are stacked in sequence in a direction perpendicular to the sliding plane, and the sliding directions of the plurality of movable frames 2 are parallel to each other.

[0035] The fixed frame 1 is used as the base of the entire handle bracket, which is used to support a single handle and to install all the movable frames 2. All the movable frames 2 are slidably installed on the fixed frame 1, and multiple movable frames 2 are installed in a stacked relationship in sequence.

[0036] The number of the mobile racks 2 is at least two. In the following description, two mobile racks 2 are used as an example to illustrate that the handle bracket can change the relative position between each handle, and can make some of the handles relatively fixed but relatively movable relative to other handles, but those skilled in the art should be able to modify the following description and apply the description to the case where there are more mobile racks 2 after appropriate modification in details.

[0037] In this embodiment, there are two mobile racks 2. For the sake of clarity, the two mobile racks 2 are defined as a first mobile rack 210 and a second mobile rack 220. A handle (not shown) may be placed on the fixed rack 1 and each mobile rack 2.

[0038] In addition, the fixed frame 1 and each mobile frame 2 are provided with a mounting and locking structure for mounting and fixing the handle. The mounting and locking structure of the fixed frame 1 and the mounting and locking structure of the mobile frame 2 can be the same or different. Preferably, the mounting and locking structures of the two are the same, which simplifies the structure of the entire handle bracket and reduces the manufacturing cost. Those skilled in the art should know that there are many ways to implement the mounting and locking structure, and at least one can be selected to perform, as long as the mounting and locking structure can be used to mount and fix the handle and unlock the handle.

[0039] Please refer to Figure 1 and Figure 2In an optional embodiment, the installation and locking structure of the fixed frame 1 includes a mounting groove 11 for accommodating the handle and a locking screw 12 for locking the handle; the mounting groove 11 on the fixed frame 1 is provided with an opening in a direction perpendicular to the sliding plane of the mobile frame 2 and a through opening in a direction parallel to the sliding direction of the mobile frame 2, which is conducive to the rapid installation and removal of the handle; at the same time, the locking screw 12 on the fixed frame 1 is arranged on one side of the mounting groove 11, which can quickly lock and unlock the handle.

[0040] Please refer to Figure 1 , Figure 3 and Figure 4 In an optional embodiment, the installation and locking structure of the mobile frame 2 includes a mounting groove 21 for accommodating the handle and a locking screw 22 for locking the handle; the mounting groove 21 of the mobile frame 2 is provided with an opening in a direction perpendicular to the sliding plane of the mobile frame 2 and a through opening in a direction parallel to the sliding direction of the mobile frame 2, which is also conducive to the rapid installation and removal of the handle; at the same time, the locking screw 22 of the mobile frame 2 is provided on one side of the mounting groove 21, and the handle can be quickly locked and unlocked. The model and specification of any one of the locking screws 12 or 22 are not limited. In some embodiments, the locking screw 12 or 22 can be tightened with the screw hole on the handle, or one end of the locking screw 12 or 22 directly abuts against the outer surface of the handle to lock the handle by friction.

[0041] It should be further explained that the present application has no special restrictions on the specific structure of the installation and locking structure. Therefore, in addition to the structures listed in the above embodiments, technicians in the relevant field can find other alternatives based on the description of the present application to achieve the functions recorded in the present application / achieve the above effects, not just the solutions disclosed in the embodiments of the present application. For example, in some other embodiments, the installation and locking structure can use a boss to position the handle, or use a boss and a mounting groove to position the handle at the same time, and in addition to the locking screw, the handle can also be locked or unlocked by a latch, a buckle or other common mechanical locking structures.

[0042] The shape and size of the mounting groove 11 on the fixed frame 1 are compatible with or not compatible with the handle, preferably compatible. Similarly, the shape and size of the mounting groove 21 on the mobile frame 2 are compatible with or not compatible with the handle, preferably compatible. However, the shapes of the mounting groove 11 on the fixed frame 1 and the mounting groove 21 on the mobile frame 2 include but are not limited to the U-shape described in the figure. In other cases, the mounting groove 11 and the mounting groove 21 can be set to be such as V-shaped, C-shaped or other shapes that can accommodate the handle.

[0043] Further, in actual use, the fixed frame 1 is always stationary, and each mobile frame 2 has a locked state and an unlocked state; the mobile frame 2 remains stationary relative to the fixed frame 1 or another mobile frame 2 connected thereto in the locked state, and can slide relative to the fixed frame 1 or another mobile frame 2 connected thereto in the unlocked state. In the present application, only the first mobile frame 210 is directly connected to the fixed frame 1, and the remaining mobile frames 2 are indirectly connected to the fixed frame 1 through the first mobile frame 210, and each mobile frame 2 can move relative to the fixed frame 1 after being unlocked and remain stationary relative to the fixed frame 1 after being locked.

[0044] For example, the first mobile frame 210 is locked and the second mobile frame 220 is unlocked. At this time, the fixed frame 1 and the first mobile frame 210 remain relatively fixed, and the second mobile frame 220 can move relative to the fixed frame 1 and the first mobile frame 210. Alternatively, the second mobile frame 220 is locked and the first mobile frame 210 is unlocked. At this time, the first mobile frame 210 and the second mobile frame 220 remain relatively fixed as a whole, so that the first mobile frame 210 and the second mobile frame 220 can move relative to the fixed frame 1. Alternatively, the first mobile frame 210 and the second mobile frame 220 are both unlocked. At this time, the second mobile frame 220 can move relative to the first mobile frame 210 and the fixed frame 1, and the first mobile frame 210 can move relative to the second mobile frame 220 and the fixed frame 1. Accordingly, the relative position between the handles can be adjusted more flexibly, and the requirements of the relative position relationship between the catheters connected to the handles in the clinical or test process can be better met.

[0045] It should also be noted that when using the handle bracket, you can choose to install a fixed handle on all the mounting and locking structures, or you can choose to install a fixed handle on part of the mounting and locking structures. That is to say, each time you use it, you can selectively use part or all of the movable frame 2 and the fixed frame 1, that is, the number of mounting points on the handle bracket can be the same as or different from the number of handles.

[0046] With such configuration, on the one hand, the present application can load and fix multiple handles through the fixed frame 1 and the movable frame 2, thereby freeing the doctor's hands, improving surgical efficiency, and enhancing surgical results. On the other hand, the movable frame 2 can move relative to the fixed frame 1, and the movable frames 2 can move relative to each other, which can not only change the relative position of each handle, but also make some of the handles remain relatively fixed but move relative to other handles. In this way, the relative position of the handles can be adjusted at any time according to clinical needs to avoid the doctor's hand-held operation, which will greatly improve work efficiency, save surgical time, improve surgical efficiency, and increase surgical safety.

[0047] In a further improvement, each mobile rack 2 is provided with a plurality of locking positions in its sliding direction, and each mobile rack 2 is in a locked state after being locked at a corresponding locking position. In this way, the mobile rack 2 can be locked in a suitable position through a plurality of locking positions. The number of the locking positions can be determined according to the range of movement of each mobile rack 2 during actual use, and as many locking positions as possible are set within the range of movement. The locking positions can be understood as structural features on the mobile rack 2 that can be locked, such as an optional lock hole or other structure that can be locked.

[0048] The present application does not particularly limit the locking method between the fixed frame 1 and the mobile frame 2 and the locking method between the mobile frames 2. In practice, in addition to thread locking, other mechanical structure locking methods known in the art may also be used, such as snap locking, latch locking, etc.

[0049] Specifically in this embodiment, the first mobile frame 210 is locked with the fixed frame 1 via a threaded fastener 13 , and the threaded fastener 13 is directly disposed on the fixed frame 1 .

[0050] Specifically in this embodiment, two adjacent stacked mobile racks 2 are locked by a threaded fastener 23, and the threaded fastener 23 is directly set on one of the two adjacent stacked mobile racks 2. This structure is simple, can be quickly locked and unlocked, and is easy to operate.

[0051] When there is a need for relative movement between the handles, the corresponding threaded fasteners 13 or 23 are rotated to unlock the handles so that the corresponding handles can move relative to each other.

[0052] When the first mobile frame 210 is locked with the fixed frame 1, the threaded fastener 13 can be tightened with the screw hole on the first mobile frame 210, or one end of the threaded fastener 13 is directly rotated against the surface of the first mobile frame 210 to achieve the locking of the first mobile frame 210 by friction.

[0053] When two adjacent mobile racks 2 are locked, the threaded fastener 23 can be tightened with the screw hole on the corresponding mobile rack 2, or one end of the threaded fastener 23 can be directly rotated against the surface of the corresponding mobile rack 2 to achieve locking of the mobile rack 2 by friction.

[0054] In some special usage scenarios, the threaded fastener 13 between the first mobile frame 210 and the fixed frame 1 can be loosened, and the threaded fasteners 23 between the multiple mobile frames 2 can be kept in a fastened state, so that the multiple handles on the multiple mobile frames 2 can remain relatively still, but can move relative to the handle fixed on the fixed frame 1.

[0055] The structures of the fixed frame 1 and the movable frame 2 are further described below.

[0056] Please refer to Figure 1 and Figure 2 In a preferred embodiment, the fixing frame 1 adopts a hollow frame structure with a simple structure and convenient processing and manufacturing. This frame structure is light in weight, uses less materials, and has a small volume. However, in other embodiments, the fixing frame 1 can adopt a non-frame structure.

[0057] In addition to the triangle shown in the figure, the outer shape of the fixing frame 1 can actually adopt other shapes, such as trapezoid, cylinder, rectangle or other regular or irregular shapes, which is not limited in the present application.

[0058] Preferably, the fixing frame 1 comprises a triangular base 110. The triangular base 110 can be used to stably place the entire handle bracket at a designated position, for example, on an operating table or a laboratory table.

[0059] The bottom 1101 of the triangular base 110 is used to be placed on a horizontal plane. The top 1102 of the triangular base 110 is arranged at an acute angle to the bottom 1101. The angle between the side 1103 of the triangular base 110 and the bottom 1101 is not limited, for example, it can be a right angle, an acute angle or an obtuse angle, and a right angle or an acute angle is more suitable.

[0060] The angle α between the top 1102 and the bottom 1101 of the triangular base 110 is adapted to the angle at which the catheter connected to the handle enters the human body, so that the catheter connected to the handle can enter and exit the human body more smoothly. Preferably, the angle α is 15°-45°.

[0061] Furthermore, the fixed frame 1 further comprises a bracket 120 fixed on the triangular base 110, and the bracket 120 is provided with a mounting locking structure. The bracket 120 is used to directly mount the fixed handle. In this embodiment, the bracket 120 is fixed on the top 1102 of the triangular base 110 at a position adjacent to the bottom 1101, and the first mobile frame 210 can slide on the top 1102 of the triangular base 110 along the length direction of the top 1102 when in the unlocked state. This structure is simple as a whole, easy to manufacture, and low in cost.

[0062] Continue to refer to Figure 2 A track 1104 is provided at the top 1102 of the triangular base 110 , and the track 1104 slidably cooperates with the slide rail 211 on the first movable frame 210 , so that the first movable frame 210 slides directly on the fixed frame 1 along the track 1104 , and the extension direction of the track 1104 is consistent with the length direction of the top 1102 .

[0063] In addition, threaded fasteners 13 are provided beside the fixed frame 1 and the rail 1104. For example, in this embodiment, the threaded fasteners 13 are provided on the side of the top 1102 of the triangular base 110. When the first movable frame 210 slides on the fixed frame 1, it can be locked by rotating the threaded fasteners 13 when it moves to a desired position, thereby ensuring the relative position of the first movable frame 210 and the fixed frame 1.

[0064] Please refer to Figure 3 , the first mobile rack 210 is provided with a slide rail 211. The structure of the track 1104 on the fixed rack 1 can be various, including but not limited to the structure shown in the figure, as long as the fixed rack 1 and the first mobile rack 210 can be slidably matched and the first mobile rack 210 can be ensured not to be separated from the fixed rack 1 when sliding. Similarly, the adjacent stacked mobile racks 2 can be slidably connected through the cooperation of the track and the slide rail. For example Figure 3 As shown, the first mobile rack 210 is further provided with a track 212, which is slidably matched with the slide rail 221 on the second mobile rack 220. Therefore, when there are more mobile racks 2, the adjacent stacked mobile racks 2 are also slidably connected in a similar manner to the track and the slide rail.

[0065] Furthermore, there is sliding contact or rolling contact between the fixed frame 1 and the movable frame 2, and there is sliding contact or rolling contact between two adjacent stacked movable frames 2. The use of rolling contact is conducive to reducing friction and sliding resistance.

[0066] The movable frame 2 may include various structural designs, such as arc, straight line, broken line, curve, etc. In order to simplify the structure of the entire handle bracket, each movable frame 2 is preferably an L-shaped structural member, so that each movable frame 2 is provided with a mounting locking structure through the vertical portion 201 of its L-shaped structural member, and the vertical portion 201 protrudes in a direction away from the fixed frame 1 and is perpendicular to the sliding plane. Among them, the first movable frame 210 is slidably connected to the fixed frame 1 through the transverse portion 202 of its L-shaped structural member, and the two adjacent stacked movable frames 2 are slidably connected to the transverse portion 202 through the transverse portion 202 of the L-shaped structural member.

[0067] Both the movable frame 2 and the fixed frame 1 can be formed by cutting plates, such as by wire cutting, and are easy to manufacture.

[0068] In a specific embodiment, the transverse portion 202 of the first mobile rack 210 is provided with a track 212 on its inner side, and a slide rail 211 is provided on the outer side opposite to the inner side, and is connected to the fixed rack 1 through the track 212 on one hand, and is connected to another adjacent mobile rack 2 through the slide rail 211 on the other hand. If the second mobile rack 220 is the last mobile rack 2, it only needs to be provided with a slide rail 221 on the outer side of the transverse portion 202, and no further track is required.

[0069] Finally, according to the technical solution provided in the above embodiment, it can be known that the present application can load multiple handles on the fixed medical device product through the fixed frame 1 and the mobile frame 2, thereby freeing the doctor's hands, improving the surgical efficiency, and enhancing the surgical effect. In addition, the mobile frame 2 can move relative to the fixed frame 1, and the mobile frames 2 can move relative to each other, which can change the relative position between each handle, and make some of the handles remain relatively fixed but can move relative to other handles. In this way, it is convenient for doctors to adjust the relative position between the handles at any time according to clinical needs, avoiding the doctor's hand-held operation, which will greatly improve work efficiency, save surgical time, improve surgical efficiency, and increase surgical safety.
