Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular to a valve clamp device and a valve clamping system. Background Art

[0002] The mitral valve is a one-way valve located between the left atrium and the left ventricle of the heart. A normal and healthy mitral valve can control the blood flow from the left atrium to the left ventricle, while preventing the blood from flowing from the left ventricle to the left atrium to form a backflow. In the related art, a clamping device is often used to clamp the valve leaflet to prevent the formation of the backflow.

[0003] During the operation, doctors can only determine the opening and closing angle of the valve clip in the body through DSA (Digital Subtraction Angiography), digital subtraction angiography or ultrasound images. When the valve clip clamps the valve leaflets, if the closing angle of the valve clip is too small or the valve leaflets are subjected to large local forces, it is easy to cause damage to the valve leaflets; similarly, if the valve clip angle is opened too much, it will damage the mechanical structure of the valve clip, causing device failure and thus affecting the progress of the operation. However, when the clamping status of the valve clip is determined by DSA or ultrasound images, doctors cannot intuitively evaluate the clamping effect of the valve clip, so the operation time is long and the efficiency is low.

DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0062] First, as Figure 1-4 As shown, Figure 1 A schematic diagram of the structure of a valve clamp device 1 provided in an embodiment of the present application. A valve clamp device 1 provided in an embodiment of the present application comprises: a body 100, a core wire 150, a pusher 140, a valve clamp 110 and an indication mechanism 160, wherein the body 100 has a channel 11 penetrating the body 100; the core wire 150 is located in the channel 11 of the body 100, and both ends of the core wire 150 extend out of the channel 11, and the core wire 150 moves along a preset direction relative to the body 100, and the preset direction is parallel to the length direction of the channel 11; the pusher 140 is relatively fixed to one end of the core wire 150, and the pusher 140 is at least partially located in the channel 11 of the body 100; the valve clamp 110 is connected to the other end of the core wire 150, and the movement path of the core wire 150 is used to control the opening and closing angle of the valve clamp 110. The indicating mechanism 160 is disposed on the main body 100 and is in direct or indirect contact with the core wire 150 . The movement path of the core wire 150 determines a corresponding relationship with the opening and closing angle of the valve clip 110 . The indicating mechanism 160 is used to convert the corresponding relationship into a scale and display it on the outer surface of the main body 100 .

[0063] In the above scheme, the valve clamp device 1 provided in the present application includes a main body 100, a core wire 150, a pushing member 140, a valve clamp 110 and an indicating mechanism 160; the core wire 150 is located in the channel 11 of the main body 100, and moves along a preset direction relative to the main body 100, both ends of the core wire 150 extend out of the main body 100, the pushing member 140 is relatively fixed to one end of the core wire 150, and the pushing member 140 is at least partially located in the channel 11 of the main body 100, the valve clamp 110 is connected to one end of the core wire 150, and the movement path of the core wire 150 is used to control the opening and closing angle of the valve clamp 110, that is, the movement distance of the core wire 150 along the preset direction has a corresponding relationship with the opening and closing angle of the valve clamp 110, and the opening and closing angle of the valve clamp 110 is adjusted by controlling the core wire 150. When the valve clamp device 1 provided by the present application is specifically operated, the valve clamp 110 is delivered into the left ventricle through the femoral vein, the valve clamp 110 is opened and clamped to the widest position of the valve leaflet regurgitation beam, and the valve clamp 110 is controlled to close to a suitable angle through the core wire 150, so as to reduce or eliminate the symptoms of regurgitation. An indicating mechanism 160 with an angle opening and closing indication function is arranged on the main body 100, and the movement path of the core wire 150 determines a corresponding relationship with the opening and closing angle of the valve clamp 110. The indicating mechanism 160 is used to convert the corresponding relationship into a scale and display it on the outer surface of the main body 100, so that the doctor can intuitively observe or feel the opening and closing angle of the valve clamp 110 in vitro, thereby improving the efficiency of the operation and reducing surgical complications.

[0064] like Figure 2 and Figure 3 As shown, Figure 2 A schematic structural diagram of the valve clip 110 provided in an embodiment of the present application in an open state; Figure 3 The schematic diagram of the structure of the valve clip 110 in the embodiment of the present application in the closed state. For ease of understanding, the connecting shaft 111 in the valve clip 110 is detachably connected to the other end of the core wire 150, for example, the connecting shaft 111 and the other end of the core wire 150 are threadedly connected, for example, the connecting shaft 111 and the other end of the core wire 150 are plugged, and the movement of the connecting shaft 111 is controlled by the movement of the core wire 150 in a preset direction, so that the valve clip 110 can be opened and closed. It can be understood that in Figure 2 In the figure, the arrow indicates the movement direction of the core wire 150, that is, when the core wire 150 moves toward the left, the connecting shaft 111 connected to the core wire 150 drives the valve clip 110 to open, that is, the valve clip 110 is in a fully opened state at this time, and the angle of the valve clip 110 is 270°. Figure 3 In the figure, the arrow indicates the movement direction of the core wire 150, that is, when the core wire 150 moves toward the right, the connecting shaft 111 connected to the core wire 150 drives the valve clip 110 to close, that is, the valve clip 110 is in a completely closed state at this time, and the angle of the valve clip 110 is 0° at this time.

[0065] Continue to refer Figure 1 The body 100 includes a handle 120 and a rotating member 130; since the pusher 140 is relatively fixed to the core wire 150, the pusher 140 is at least partially located in the channel 11 of the handle 120, so when the rotating member 130 rotates, the rotating member 130 arranged on the outer surface of the pusher 140 rotates to make the pusher 140 reciprocate along a preset direction relative to the handle 120, and the core wire 150 relatively fixed to the push rod also reciprocates along the preset direction. When the pusher 140 is in an initial state relative to the handle 120, the valve clip 110 connected to the core wire 150 is at an initial angle, where the initial angle of the valve clip 110 is 180°. The rotating member 130 is arranged at the tail end of the handle 120, that is, arranged on the right side of the handle 120, and the rotating member 130 can rotate relative to the handle 120. The rotating member 130 and the pushing member 140 are connected by threads. When the rotating member 130 is rotated, the pushing member 140 only moves in the left and right axial direction, that is, the pushing member 140 only reciprocates in a preset direction without rotating in the circumferential direction. The valve clip 110 is a connecting rod mechanism. By rotating the rotating member 130, the core wire 150 moves in the axial direction, thereby controlling the opening angle of the valve clip 110.

[0066] Regarding the different contact modes between the indicating mechanism 160 and the core wire 150 , for the convenience of understanding the solution, the different contact modes between the indicating mechanism 160 and the core wire 150 are specifically described below:

[0067] like Figure 4-Figure 14 As shown, when the indicator mechanism 160 is in direct contact with the core wire 150, the indicator mechanism 160 is located on the handle 120; the core wire 150 includes a push portion 15; the indicator mechanism 160 is arranged in contact with the push portion 15, and the axial movement distance of the push portion 15 along the preset direction is converted into an angle display on the indicator mechanism 160. That is, the axial movement of the core wire 150 along the preset direction causes the push portion 15 to move together, so that the indicator mechanism 160 in direct contact with the push portion 15 is actuated, and the axial movement distance is directly displayed on the indicator mechanism 160 at an angle, and the displayed angle corresponds to the angle of the valve clip 110. Because the indicator mechanism 160 is located on the outer surface of the handle 120, the doctor can accurately observe the angle value on the indicator mechanism 160, that is, accurately observe the closed angle of the valve clip 110, avoid the phenomenon of excessive clamping of the valve leaflet, thereby damaging the valve leaflet; and also accurately observe the opening angle of the valve clip 110. When the valve clip 110 is excessively opened, the valve clip 110 is at risk of being damaged.

[0068] Of course, there are many options for the specific structure of the indicator mechanism 160. For ease of understanding, the indicator mechanism 160 specifically includes the following structures:

[0069] Structure 1, reference Figure 4-Figure 10 .exist Figure 4 In the embodiment, the handle 120 has a groove 121, and the groove 121 is connected to the channel 11 of the body 100. For the specific structure of the indicating mechanism 160, please refer to Figure 5 The indicating mechanism 160 includes a first indicating plate 163, a first pointer 164 parallel to the first indicating plate 163, a first gear 162 and a lifting rod 161; the first indicating plate 163 is mounted on the handle 120, the first pointer 164 is rotatably disposed on the first indicating plate 163 via a first rotating shaft 165, the first gear 162 is disposed on the first rotating shaft 165 and is relatively fixed to the first rotating shaft 165. The lifting rod 161 has a first end and a second end that are disposed opposite to each other, the first end of the lifting rod 161 extends from the groove 121 into the channel 11 of the handle 120, the second end of the lifting rod 161 is located outside the notch of the groove 121, and the lifting rod 161 is formed with meshing teeth that mesh with the first gear 162. The pushing portion 15 has a first inclined surface 151 and a second inclined surface 152 connected along a preset direction, and the end of the lifting rod 161 is always in contact with the first inclined surface 151 or the second inclined surface 152; when the pushing member 140 is in an initial state relative to the handle 120, the lifting rod 161 is at the intersection A of the first inclined surface 151 and the second inclined surface 152. Figure 4 The indicating mechanism 160 further includes an elastic member 166 ; the elastic member 166 is disposed between the lifting rod 161 and the groove wall of the groove 121 , and is used to provide elastic potential energy to the lifting rod 161 to always be in contact with the first inclined surface 151 or the second inclined surface 152 .

[0070] When the lifting rod 161 is located at the junction A of the first inclined surface 151 and the second inclined surface 152 , that is, the valve clip 110 is in a 180° open state, the first pointer 164 at this time points to the 180° scale on the first indicator plate 163 . When the core wire 150 moves to the left, the valve clip 110 opens from the initial state of 180° to the open state of 270°, the second inclined surface 152 of the pushing part 15 pushes the lifting rod 161 upward by a distance H2, the first gear 162 meshed with the lifting rod 161 rotates a corresponding angle, and the first gear 162 drives the first pointer 164 to rotate to indicate the opening angle of the valve clip 110; when the core wire 150 moves to the right from the initial state, the first inclined surface 151 of the core wire 150 pushing part 15 pushes the lifting rod 161 upward by a distance H1, the first gear 162 meshed with the lifting rod 161 rotates a corresponding angle, and the first gear 162 drives the first pointer 164 to rotate to indicate the closing angle of the valve clip 110. It should be pointed out that the present invention takes the valve clip 110 at 180° as the zero point of opening and closing, the angle opening range is 180°-270°, and the angle closing range is 180°-0°. Since the absolute values ​​of the opening and closing angle changes are different, the embodiment of the present application has different inclination angles through the first inclined surface 151 and the second inclined surface 152, and the distances H1 and H2 by which the lifting rod 161 is pushed upward are also different, so the amplitude of the pointer knob is also different accordingly.

[0071] In some specific embodiments, Fig. 9 As shown, when the core wire 150 moves axially to the left, the valve clip 110 opens from the initial angle of 180° to a maximum of 270°. Due to the action of the second inclined surface 152, the lifting rod 161 moves upward, driving the first gear 162 and the first pointer 164 to rotate clockwise, and accordingly, the reading of the first pointer 164 gradually indicates from 180° to 270°. Preferably, the pushing portion 15 includes a first stopper 154 and a second stopper 153; the first stopper 154 is arranged at one end of the first inclined surface 151 away from the second inclined surface 152; the second stopper 153 is arranged at one end of the second inclined surface 152 away from the first inclined surface 151.

[0072] When the lifting rod 161 contacts the second stopper 153, the core wire 150 cannot continue to move axially to the left, thereby preventing the valve clip 110 from over-opening and damaging its mechanical structure. Similarly, when the core wire 150 moves to the right, the valve clip 110 changes from an open state to a closed state, and the pointer indicates from 180° to 0°. The first stopper 154 also serves to limit the core wire 150 from excessively moving to the right and damaging the valve leaflet.

[0073] For details, please refer to Fig.10, the first slope 151 and the second slope 152 have different inclination angles. In the preset direction, the length of the first slope 151 is L1, the length of the second slope 152 is L2, L1=nL2, and the range of n is 1.4-1.6; for example, n is 1.40, 1.45, 1.50, 1.55, or 1.6; the height of the first slope 151 is H1, the height of the second slope 152 is H2, H1=mH2, and the range of m is 1.9-2.1; for example, m is 1.90, 1.95, 2.0, 2.05, or 2.10. The initial position of the lifting rod 161 is located at the junction of the first slope 1511 and the second slope 152, that is, the valve clip 110 is at 180°. When the lifting rod 161 is on the first inclined surface 151, the core wire 150 moves axially by a distance L1, and the corresponding height change of the lifting rod 161 is H1; when the lifting rod 161 is on the second inclined surface 152, the core wire 150 moves axially by a distance L2, and the corresponding height change of the lifting rod 161 is H2. Preferably, L1=1.5L2, H1=2H2.

[0074] Structure 2, such as Figure 11-Figure 14 The indicating mechanism 160 includes a second indicating disk 173, a second pointer 174 parallel to the second indicating disk 173, and a second gear 172. The handle 120 has a groove 121, and the groove 121 is connected to the channel 11 of the body 100. The second indicating disk 173 is installed on the handle 120. The second pointer 174 is rotatably arranged on the second indicating disk 173 through a second rotating shaft 175. The second gear 172 is sleeved on the second rotating shaft 175 and is relatively fixed to the second rotating shaft 175; the pushing portion 15 forms meshing teeth meshing with the second gear 172.

[0075] When the core wire 150 moves axially to the left, the pusher 15 on the core wire 150 meshes with the second gear 172, causing the second gear 172 to rotate in a first direction, the first direction being clockwise, thereby driving the second rotating shaft 175 fixed relatively to the second gear 172 to rotate together, and the second pointer 174 connected to the second rotating shaft 175 also rotates clockwise, and the valve clip 110 opens from the initial angle of 180° to the maximum of 270°. Accordingly, the reading of the second pointer 174 gradually indicates from 180° to 270°.

[0076] Similarly, when the core wire 150 moves axially to the right, the pushing portion 15 on the core wire 150 engages with the second gear 172, causing the second gear 172 to rotate in a second direction, which is counterclockwise, thereby driving the second rotating shaft 175 fixed relatively to the second gear 172 to rotate, and the second pointer 174 connected to the second rotating shaft 175 also rotates counterclockwise, and the valve clip 110 closes from the initial angle of 180° to 0°. Correspondingly, the reading of the second pointer 174 gradually indicates from 180° to 0°.

[0077] Structure three, such as Fig.15 As shown, the indicating mechanism 160 includes a third indicating disk, a third pointer (not shown) parallel to the third indicating disk, and a third gear set 180. The third gear set 180 includes two coaxial spur gears A181 and spur gear B182 with the same rotation speed. The spur gear A181 and the spur gear B182 are fixedly connected. The spur gear A181 and the spur gear B182 are different in size. Specifically, the diameter of the spur gear A181 is smaller than the diameter of the spur gear B182. The modules of the spur gear A181 and the spur gear B182 are equal or different. In some embodiments, the module of the spur gear A181 is equal to the module of the spur gear B182.

[0078] In some embodiments, the third indicator disc is installed in the same manner as the first indicator disc or the second indicator disc. The handle has a groove, the groove is connected to the body channel, and the third indicator disc is installed on the handle. The third pointer is rotatably arranged on the third indicator disc through a third rotating shaft. The third gear set is sleeved on the third rotating shaft and is relatively fixed to the third rotating shaft.

[0079] refer to Fig.15 , the pushing portion 15 forms meshing teeth that mesh with the third gear set 180. The pushing portion 15 includes a first meshing portion 155 and a second meshing portion 156. The first meshing portion 155 is used to mesh with the spur gear A 181, and the second meshing portion 156 is used to mesh with the spur gear B 182. The first meshing portion 155 and the second meshing portion 156 do not overlap in a preset direction, that is, in the preset direction, the first meshing portion 155 and the second meshing portion 156 are not provided with meshing teeth at the same time.

[0080] Further references Fig.15 , the height of the first meshing portion 155 in the vertical direction is greater than the height of the second meshing portion 156 in the vertical direction. The height settings of the two need to meet the meshing requirements of the spur gear A and the spur gear B. The modules of the spur gear A 181 and the spur gear B 182 are respectively the same as the modules of the first meshing portion 155 and the second meshing portion 156.

[0081] In the preset direction, the first meshing portion 155 of the pushing portion 15 is divided into a first section provided with meshing teeth and a second section without meshing teeth. The height difference between the first section and the second section in the vertical direction is greater than the module of the meshing teeth, so that when the spur gear A181 is not meshing, it does not contact the part of the pushing portion without meshing teeth. Similarly, the second meshing portion 156 of the pushing portion 15 is also divided into a first section provided with meshing teeth and a second section without meshing teeth. The height difference between the first section and the second section in the vertical direction is greater than the module of the meshing teeth, so that when the spur gear B182 is not meshing, it does not contact the part of the pushing portion without meshing teeth.

[0082] In actual operation, the movement of the rotating member drives the core wire 150 and the pushing part 15 to move in a preset direction. When the pushing part moves to mesh with the spur gear A181 or the spur gear B182 on the third gear set, the third gear set is driven to rotate, thereby converting the movement of the core wire 150 in the preset direction into the rotation of the pointer on the third indicator disk.

[0083] like Fig.16 As shown, in some specific embodiments, the valve clip device 1 further includes a fixing member 141; the pusher 140 has a mounting groove 145, the mounting groove 145 is communicated with the channel 11 of the pusher 140, the fixing member 141 is located in the mounting groove 145, and the fixing member 141 is fixed to the core wire 150. For example, the fixing member 141 can be a structure such as a screw, and the core wire 150 is fixed to the pusher 140 by a common method such as a pointed screw, so as to ensure that the two maintain consistent axial movement without loosening.

[0084] Second, as Fig.17 As shown, a valve clip system 110 provided in the present application comprises a monitoring device 2 and the valve clip device 1 of any one of the first aspects;

[0085] The monitoring device 2 is connected to the valve clip device 1 and is used to monitor the clamping state of the valve clip 110 .
