[0035] The utility model aims to provide a handle supporting tool and a handle supporting device to solve the problem that the operator holds the handle and operates the handle.
[0036] 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.
[0037] Please refer to Figures 1 to 10 In various embodiments of the present application, a handle support tool is provided, which can be used to install various medical device handles, especially catheter interventional medical device handles. Interventional medical devices are various interventional devices that can be understood by those skilled in the art.
[0038] Specifically, the handle supporting tool comprises: a fixing seat 100; and two closing pieces hinged on the fixing seat 100; the two closing pieces are respectively a first closing piece 200 and a second closing piece 300; the first closing piece 200 and the second closing piece 300 are arranged opposite to each other and are used to clamp the medical device handle 400 to maintain the stability of the medical device handle 400. In particular, the medical device handle 400 can further rotate in its own circumferential direction after being clamped by the two closing pieces.
[0039] In various embodiments of the present application, the shape and size of the medical device handle 400 are not limited. The structure of the medical device handle 400 is various structural forms that can be understood by those skilled in the art, such as round, square, arc, gun-shaped, etc. Different medical device handles 400 can have different structural designs. The medical device handle 400 involved in the present application can be an integral type, a combined type, or a split type, which is not limited.
[0040] Based on the above-mentioned hinge, both closing pieces can be rotated to open and close relative to the fixing seat 100, and can be switched between an unlocked state and a locked state. The two closing pieces can be distributed up and down, left and right, or front and back on the fixing seat 100. In a preferred embodiment, the two closing pieces are distributed left and right on the fixing seat 100, so that the two closing pieces define a loading space with an opening facing upward, and then the medical device handle 400 can be loaded into or taken out of the loading space along the up and down direction, which facilitates the removal and installation of the medical device handle 400.
[0041] The handle support tool further comprises a locking structure 500 connected to the fixing seat 100 and the closing piece. The locking structure 500 is used to lock and unlock the closing piece. Specifically, each closing piece has a locked state and an unlocked state; when the closing piece is in the locked state, the locking structure 500 locks the closing piece and the fixing seat 100, so that the closing piece cannot rotate relative to the fixing seat 100; when the closing piece is in the unlocked state, the locking structure 500 releases the lock on the closing piece and the fixing seat 100, so that the closing piece can rotate relative to the fixing seat 100. The two closing pieces can rotate independently, and each reciprocates between the unlocked position and the locked position.
[0042] In order to quickly install the medical device handle 400, each closing piece is suitable for a lever structure, that is, the rotation fulcrum formed by the hinge between each closing piece and the fixing seat 100 (that is, the fixing point around which the closing piece rotates) is set between the first end and the second end of the closing piece, and rotates around the rotation fulcrum. Further, the handle support tool is configured so that when the medical device handle 400 is installed, the second end of each closing piece can rotate around the rotation fulcrum under the pressure of the medical device handle 400, thereby driving the locking structure 500 to lock the closing piece. That is to say, after the closing piece is in the unlocked state, when the medical device handle 400 is installed, the power is the pressure provided by the medical device handle 400, and the power is applied to the second end of the closing piece, so that the closing piece rotates around the rotation fulcrum in the closing direction of the closing piece until the locking structure 500 locks the closing piece with the fixing seat 100 and no longer rotates. When unlocking the closing piece, the locking force between the fixing seat 100 and the closing piece is overcome, and power is applied to the first end of the closing piece. Under the action of the power of the first end, the closing piece is rotated around the rotation fulcrum in the opening direction of the closing piece until the closing piece and the fixing seat 100 are unlocked. However, it should be understood that when the medical device handle 400 is not installed, after the closing piece is in the unlocked state, it is necessary to manually act on the first end or the second end of the closing piece to cause the closing piece to rotate around the rotation fulcrum in the closing direction, thereby locking the closing piece and the fixing seat 100. Therefore, based on the lever principle, pressure is directly applied to the second end of the closing piece through the medical device handle 400 to achieve autonomous locking of the closing piece, which saves the step of manually operating the closing piece, making the operation more convenient and providing a better operating experience for the user.
[0043] In addition, as mentioned above, the medical device handle 400 can perform rotational movement in its own circumferential direction. To this end, a limiting structure 110 is provided on the fixing seat 100, and the limiting structure 110 is used to cooperate with the medical device handle 400, thereby limiting the movement of the medical device handle 400 in its own axial direction, but allowing the medical device handle 400 to perform rotational movement in its own circumferential direction. The limiting structure 110 is provided so that the medical device handle 400 can still complete the rotational movement when it is clamped by the closing piece, and then when the handle 400 needs to be rotated, there is no need to remove the handle 400 from the entire tool and hold it in hand to rotate the handle, which can completely free the operator's hands and improve efficiency.
[0044] Therefore, after using the handle supporting tool provided in the present application, the medical device handle 400 can be directly fixed by this tool to maintain the stability of the medical device handle 400, so that the operator can concentrate on operating the handle 400, reduce operation risks, and improve operation efficiency.
[0045] Figures 3 to 5In the illustrated embodiment, the locking structure 500 includes a first portion 510 disposed on the closing piece and a second portion 520 disposed on the fixing seat 100, that is, each closing piece is provided with the first portion 510, and each closing piece is connected and fixed to the second portion 520 on the fixing seat 100 through the first portion 510. Specifically, the first portion 510 and the second portion 520 can be connected, thereby locking the closing piece so that the closing piece cannot rotate relative to the fixing seat 100; the first portion 510 and the second portion 520 can also be disconnected, thereby unlocking the closing piece, and then allowing the closing piece to rotate relative to the fixing seat 100. In this way, when the medical device handle 400 is installed, the second end of each closing piece can rotate around the rotation fulcrum under the pressure applied by the medical device handle 400, thereby driving the first portion 510 to approach the second portion 520 until it is connected to the second portion 520. This structure is simple in design, and the locking and unlocking operations are convenient and reliable. The connection method between the first part 510 and the second part 520 is various mechanical locking methods that can be connected and then separated, and can be connected again after separation, such as snap connection, magnetic connection, etc., which are not limited to this.
[0046] In a preferred embodiment, the first part 510 and the second part 520 are snap-fit connections. The snap-fit connection can be directly formed on the closing piece and the fixing seat 100, and no other accessories are required during assembly, the manufacturing cost is low, the snap-fit connection strength can meet the requirements, and the snap-fit connection can achieve quick installation and disassembly, and the disassembly process does not require auxiliary tools, so it is simpler and more convenient. In specific implementation, one of the first part 510 and the second part 520 is set as a slot 202, and the other of the first part 510 and the second part 520 is set as a snap-fit 104 that cooperates with the slot 202. Wherein the snap-fit 104 is elastic or inelastic. Preferably, the snap-fit 104 is a spring, such as a stainless steel or other metal spring. The number of the snap-fit 104 and the slot 202 is the same or different, preferably, the snap-fit 104 and the slot 202 correspond one to one. The snap-fit 104 is one or more, preferably multiple. The slot 202 is one or more, preferably multiple. When multiple snap-fits 104 and multiple slots 202 are provided, the locking is more secure.
[0047] Figure 3 In a specific embodiment described, a buckle 104 is provided on the fixing seat 100. The buckle 104 is a spring sheet. There are multiple spring sheets. Some spring sheets are buckled with the slots 202 on the first closing piece 200, and other spring sheets are buckled with the slots 202 on the second closing piece 300. When the medical device handle 400 is pressed down and placed on the fixing seat 100, it acts on the second end of each closing piece, driving the first closing piece 200 and the second closing piece 300 to rotate into place and form a buckle connection with the fixing seat 100, and finally the handle 400 is stably fixed.
[0048] Figures 1 to 3 In the illustrated embodiment, the limiting structure 110 includes one or more limiting blocks 103, which are arranged on one side of the closing piece along the direction of the rotation axis, and are used to cooperate with the medical device handle 400. The limiting block 103 and the medical device handle 400 may be matched in any manner, and the more commonly used matching manner is inlaying or other forms of connection, as long as the medical device handle 400 and the handle supporting tool are relatively fixed in the axial direction, but the rotation of the medical device handle 400 is not restricted.
[0049] Figure 6 In an exemplary embodiment described, the medical device handle 400 includes a limiting groove 401, and the limiting groove 401 is used to match the limiting protrusion on the limiting block 103. However, it should be understood by those skilled in the art that in some other embodiments, the medical device handle 400 includes a limiting protrusion, and the limiting protrusion is used to match the limiting groove on the limiting block 103, which can achieve the same effect. In other words, the medical device handle 400 and the fixing seat 100 are both provided with limiting grooves and limiting protrusions, the limiting protrusion on the medical device handle 400 matches the corresponding limiting groove on the fixing seat 100, and the limiting groove 401 on the medical device handle 400 matches the corresponding limiting protrusion on the fixing seat 100.
[0050] In a preferred embodiment, the limiting structure 110 includes two limiting blocks 103, one limiting block 103 is provided on each side of the closing piece along the direction of the rotation axis, and this structure has a better limiting effect. Figure 6 As shown, the medical device handle 400 includes two limiting grooves 401, which are arranged at intervals in the axial direction of the handle 400, and the two limiting blocks 103 are matched with the two limiting grooves 401 in a one-to-one correspondence. The limiting groove 401 is mainly an annular groove that surrounds the medical device handle 400 in a full circle, and the limiting block 103 provides a circular arc-shaped limiting protrusion. In practice, the limiting block 103 has a support surface 105 for mounting the medical device handle 400, and the inner side of the support surface 105 is provided with a circular arc-shaped limiting protrusion.
[0051] refer to Figure 2 and Figure 3 In some embodiments, the handle supporting tool further includes a stop structure 120 disposed on the fixing seat 100; the stop structure 120 is used to limit the maximum angle of the closing piece when it is opened, thereby preventing the closing piece from rotating too much to increase the travel during locking and reduce efficiency.
[0052] In an optional embodiment, the stop structure 120 includes four stoppers 102, each two stoppers 102 form a group, and are arranged on the outer side of a corresponding closing piece for stopping. However, it should be understood in the art that in some other embodiments, other numbers of stoppers 102 may be used, and it is not absolutely limited to four stoppers 102.
[0053] In this embodiment, at least two stoppers 102 respectively provide a rotation position stop (interception stop) for the first closing piece 200 and the second closing piece 300, so that the first closing piece 200 and the second closing piece 300 no longer rotate to open. Specifically, the first closing piece 200 and the second closing piece 300 are respectively stopped by at least one corresponding stopper 102. Preferably, the first closing piece 200 and the second closing piece 300 are respectively defined by two stoppers 102, and each two stoppers 102 are arranged as a group on the outside of the closing piece and are symmetrically distributed in the direction of the rotation axis of the stoppers 102. In other words, each limit block 103 is provided with two hinge bases 106 at appropriate positions along the arc direction, and the two hinge bases 106 are symmetrically arranged about the central axis of the limit block 103. Each hinge base 106 is provided with an axial hole 101. The two axial holes 101 on the same side cooperate with the axial hole 201 on the first closing piece 20 to form a hinge connection, and the two axial holes 101 on the other same side cooperate with the axial hole 201 on the second closing piece 300 to form a hinge connection, thereby providing a fulcrum for the rotation of the first closing piece 200 and the second closing piece 300.
[0054] However, those skilled in the art will appreciate that in some other embodiments, the stop structure 120 may not be provided so that the closing piece can be opened to the maximum.
[0055] Figure 4 In the specific embodiment shown, the first closing piece 200 is provided with an axial hole 201, a slot 202 and a handle 203. The axial hole 201 of the first closing piece 200 cooperates with the axial hole 101 on the left side of the fixing seat 100 to form a hinge connection, providing a fulcrum for the rotation of the first closing piece 200. The slot 202 of the first closing piece 200 forms a snap connection with the buckle 104 of the fixing seat 100, which is used to fix and release the first closing piece 200. Optionally, the handle 203 of the first closing piece 200 can be manually operated, so as to rotate the first closing piece 200 to open it and disengage the slot 202 from the buckle 104, thereby finally releasing the first closing piece 200 and the handle.
[0056] Figure 5In the specific embodiment shown, the second closing piece 300 is provided with an axial hole 201, a slot 202 and a handle 203. The axial hole 201 of the second closing piece 300 cooperates with the axial hole 101 on the right side of the fixing seat 100 to form a hinge connection, providing a fulcrum for the rotation of the second closing piece 300. The slot 202 of the second closing piece 300 forms a snap connection with the buckle 104 of the fixing seat 100, which is used to fix and release the second closing piece 300. The handle 203 of the second closing piece 300 can be manually operated, so as to rotate the second closing piece 300 to open it and disengage the slot 302 from the buckle 104, so as to finally release the second closing piece 300 and the handle.
[0057] It should be noted that the handle 203 may or may not be provided in any one of the closing pieces. After the handle 203 is provided, the closing piece can be operated more conveniently. In addition, the structures of the two closing pieces may be the same or different, preferably the same, to reduce the number of parts and reduce costs.
[0058] In some application scenarios, the handle supporting tool is placed directly on a horizontal plane, such as a horizontal plane defined by an operating table, a test table, or a laboratory table.
[0059] In other application scenarios, the handle support tool is directly placed on a bracket, and the bracket is placed on a horizontal plane defined by, for example, an operating table, a test table, or a laboratory table. Providing a bracket can more conveniently place the handle support tool on a horizontal plane, especially when the handle support tool is movable relative to the bracket, the handle support tool can be moved more labor-savingly, thereby changing the handle position and realizing the adjustable handle position.
[0060] In addition, the embodiment of the present application further provides a handle supporting device, including a bracket and a handle supporting tool installed on the bracket. The handle supporting tool is installed on the bracket through a fixing seat 100, and the handle supporting tool can move relative to the bracket or remain fixed relative to the bracket. There are one or more handle supporting tools, and when there are multiple handle supporting tools, at least one handle supporting tool can move relative to the bracket.
[0061] It should be understood that some medical device products have multiple medical device handles 400, such as two or more handles, which can provide various functions, such as bending control, delivery, release, recovery, etc. The handle support device provided by the utility model is used to install multiple medical device handles 400 used simultaneously by the corresponding medical device products, which can change the relative position between each handle, and make some of the handles relatively fixed but relatively movable relative to other handles, which is convenient for medical staff to adjust the relative position between the handles at any time according to clinical needs.
[0062] Although the present application does not show the structural shape of the bracket, those skilled in the art should be able to know how to select the structure of the bracket so that the bracket can be stably placed on a horizontal plane. In some embodiments, the bracket can be retracted to adjust the angle of the handle holding the tool relative to the horizontal plane, which is conducive to finding the best tilt angle for instrument access, making the access more accurate, convenient and safer.
[0063] The shape and size of the fixing base 100 are not limited. If the fixing base 100 is placed directly on a horizontal plane, a structure that can be placed stably can be selected. If the fixing base 100 is placed directly on a bracket, a small and lightweight structure is preferred, such as the bracket structure shown in the figure or other shapes.
[0064] Please refer to the following Figures 7 to 10 , the installation process of the medical device handle 400 is further described. Before installing the medical device handle 400, the first closing piece 200 and the second closing piece 300 are rotated and opened to the stop position, such as Figure 7 and Figure 8 As shown; then, the medical device handle 400 is placed between the first closing piece 200 and the second closing piece 300, and supported by the support surface 105; when the medical device handle 400 is placed in place, under the pressure of the medical device handle 400, the first closing piece 200 and the second closing piece 300 are rotated until the slot 202 is engaged with the buckle 104, so that the medical device handle 400 can be relatively fixed and the medical device handle 400 is allowed to rotate.
[0065] In more detail, the installation process is as follows: when the medical device handle 400 is pressed down and placed, the first closing piece 200 and the second closing piece 300 are driven to rotate toward each other, and the card slot 202 on the closing piece forms a card buckle connection with the card buckle 104 on the fixing seat 100, so as to achieve the effect of relatively fixing the medical device handle 400. At the same time, the limit slot 401 on the medical device handle 400 cooperates with the limit block 103 on the fixing seat 100, so that the medical device handle 400 can achieve its own rotation while being relatively fixed in the axial direction. Accordingly, when releasing the medical device handle 400, it is only necessary to rotate the handle 203 to disengage the card slot 202 from the card buckle 104, so as to achieve the purpose of releasing the medical device handle 400.
[0066] Finally, it needs to be further explained that the present application has no special restrictions on the specific structures of the locking structure, the limiting structure, and the stopping structure. Therefore, in addition to the structures listed in the above embodiments, technical personnel in the relevant field can find other alternative methods based on the records in the specification of this application to achieve the functions recorded in this application / achieve the above-mentioned effects, and not just the solutions disclosed in the embodiments of this application.
[0067] In summary, according to the technical solution provided in the embodiment of the present application, the above-mentioned handle supporting tool includes: a fixed seat 100; two closing pieces hinged on the fixed seat 100; a locking structure 500 connected to the fixed seat 100 and the closing piece; and a limiting structure 110 arranged on the fixed seat 100; the two closing pieces are arranged opposite to each other to clamp the medical device handle 400; a rotation fulcrum formed by each closing piece being hinged with the fixed seat 100 is arranged between the first end and the second end of the closing piece; the locking structure 500 is used to lock and unlock the closing piece; the limiting structure 110 is used to cooperate with the medical device handle 400 to limit the movement of the medical device handle 400 in its own axial direction and allow the medical device handle 400 to rotate in its own circumferential direction; and then when the medical device handle 400 is installed, the second end of each closing piece rotates around the rotation fulcrum under the pressure of the medical device handle 400, thereby driving the locking structure 500 to lock the closing piece. With such configuration, the medical device handle 400 can be directly placed on the handle supporting tool and fixed, thereby maintaining the stability of the medical device handle 400 and preventing the hand-held device from affecting the operation of the handle, thereby ensuring the effectiveness and safety of the medical device operation 400 and improving the operating efficiency.
[0068] Furthermore, when installing the medical device handle 400, the locking structure 500 can be controlled to automatically lock the closing piece based on the pressure of the medical device handle 400 on one end of the closing piece. This structure is very convenient to operate and can bring a better operating experience to the user.
[0069] Furthermore, based on the setting of the limiting structure 110, the medical device handle 400 can complete the rotational movement when clamped by the closing piece, which ultimately does not affect the rotation operation of the medical device handle 400. When the handle 400 needs to be rotated, there is no need to remove the handle from the tool and then hold it by hand to rotate it, making the operation more convenient and the handle more convenient to use.
[0070] In order to better use the handle support tool, in some cases, the handle support tool is installed on a bracket. In addition, based on the setting of the bracket, the handle support tool can be placed on a horizontal plane more conveniently. Especially when the handle support tool is movable relative to the bracket, the handle support tool can be moved more effortlessly, thereby changing the handle position and realizing the adjustable handle position.
