Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to an electrosurgical instrument and an electrosurgical system. Background Art
[0002] An ultrasonic scalpel (abbreviated as ultrasonic scalpel) is an instrument that further amplifies the ultrasonic vibration obtained by a piezoelectric converter (electric energy is transferred to the piezoelectric converter through an energy generator, and the piezoelectric converter converts the electrical energy into ultrasonic mechanical energy), and uses the amplified ultrasonic vibration at the head of the scalpel to cut and coagulate soft tissue.
[0003] In the related art, an ultrasonic scalpel includes a handle and an end effector, and the end effector of the handle includes an upper jaw member and a lower jaw member. A trigger is movably mounted on the handle, and the trigger can move relative to the handle to drive the upper jaw member and the lower jaw member to move closer to or away from each other. An excitation button and a cutting button are also mounted on the handle. In the prior art, three steps are required: the first step is to press the trigger to clamp the tissue, the second step is to press the excitation button to transmit electrosurgical energy to the end effector, and the third step is to press the cutting button to cut the electrocoagulated tissue. However, because the excitation button and the cutting button need to be operated separately with fingers, and there is a possibility of pressing the wrong button during operation, this will lead to inconvenience in operation, which not only increases the complexity of the operation, but also increases the fatigue of the operator during the operation. Summary of the invention
[0004] Based on this, it is necessary to provide an electrosurgical instrument and an electrosurgical system to address the problem of inconvenient operation of the first trigger button.
[0005] An electrosurgical instrument, comprising:
[0006] A handle, comprising a mounting member and a gripping portion connected to each other, wherein the gripping portion has a first side wall and a second side wall arranged opposite to each other;
[0007] an end effector connected to the mounting member via an elongated shaft;
[0008] a trigger, rotatably connected to the handle, and the trigger is configured to be operably pressed to move relative to the grip portion;
[0009] A first trigger button is installed on the first side wall. When the trigger is pressed by a finger at a preset position, the finger pressing the trigger can press the first trigger button to deliver electrosurgical energy to the end actuator.
[0010] In one embodiment, a second trigger button is provided on the second side wall, and either the first trigger button or the second trigger button is pressed or both are pressed simultaneously to deliver electrosurgical energy to the end effector.
[0011] In one embodiment, the outer wall of the first trigger button is concave relative to the first side wall, and the outer wall of the second trigger button is concave relative to the second side wall.
[0012] In one embodiment, the outer wall of the first trigger button is convex relative to the first side wall, and the outer wall of the second trigger button is convex relative to the second side wall.
[0013] In one embodiment, it further includes a limiting member installed on the gripping portion, wherein the limiting member has a first state and a second state;
[0014] When in the first state, the limiting member locks the first excitation button to limit the first excitation button from being excited;
[0015] When in the second state, the limiting member locks the second excitation button to prevent the second excitation button from being excited.
[0016] In one of the embodiments, a slide groove is provided on the outer wall of the gripping portion on a side away from the trigger, and the limiting member is slidably disposed in the slide groove to switch between the first state and the second state.
[0017] In one embodiment, the first firing button and the second firing button can be pressed simultaneously to deliver electrosurgical energy to the end effector.
[0018] In one embodiment, the first excitation button is in the shape of an elongated strip.
[0019] In one embodiment, the first excitation button includes a button portion and a trigger portion, and the button portion and the trigger portion are selectively connected at a single point or a multi-point connection. The button portion is used to respond to a pressing operation of the hand, and the trigger portion is used to communicate with the control system of the electrosurgical instrument.
[0020] The present application also provides an electrosurgical system, comprising a host and the electrosurgical instrument described above, wherein the host is connected to the electrosurgical instrument, and the host is used to provide excitation energy for the electrosurgical instrument and obtain control or detection signals.
[0021] In the above-mentioned electrosurgical instrument, the end effector is connected to the tool of the handle, and the trigger is connected to the handle. The trigger can be pressed to move relative to the grip portion. When the trigger is pressed at a preset position, the end effector can clamp the area to be treated. A first excitation button is installed on the first side wall of the grip portion. In actual use, the operator holds the grip portion, and when the trigger is pressed at a preset position, the finger pressing the trigger presses on the first excitation button, thereby transmitting electrosurgical energy to the end effector. Compared with the existing electrosurgical instruments, the electrosurgical instrument provided by the present application can naturally fall on the first excitation button when the operator holds the grip portion, which is convenient for pressing the first excitation button after pressing the trigger. By limiting the relative position of the first excitation button and the trigger, the handle has the advantage of intuitive control, which can simplify the operation process to a certain extent, and the original action of pressing the trigger can be used for excitation, and then the cutting button is operated independently, which is equivalent to two action processes, and there is no misoperation. The electrosurgical instrument provided in the present application is not only easy to operate and reduces the complexity of the operation, but also reduces the fatigue of the operator during the operation, improves the comfort of operation, thereby improving the accuracy of operation, simplifies the workflow, reduces the safety risks caused by misoperation, and improves surgical efficiency.

[0046] The present application provides an electrosurgical instrument, such as Figure 1As shown, the electrosurgical instrument includes a handle 100, an end actuator 200, a trigger 300 and a first excitation button 400. The handle 100 includes a connected mounting member 110 and a gripping portion 120, and the gripping portion 120 has a first side wall 121 and a second side wall 122 that are oppositely arranged; the end actuator 200 is connected to the mounting member 110 through a slender shaft 700; the trigger 300 is rotatably connected to the handle 100, and the trigger 300 is configured to be operably pressed to move relative to the gripping portion 120; the first excitation button 400 is installed on the first side wall 121, and when the trigger 300 is pressed by a finger at a preset position, the finger pressing the trigger 300 can press the first excitation button 400 to deliver electrosurgical energy to the end actuator 200.
[0047] In the above-mentioned electrosurgical instrument, the end effector 200 is connected to the tool of the handle 100, and the trigger 300 is connected to the handle 100. The trigger 300 can be pressed to move relative to the grip 120. When the trigger 300 is pressed at a preset position, the end effector 200 can clamp the area to be treated. A first trigger button 400 is installed on the first side wall 121 of the grip 120. In actual use, the operator holds the grip 120, and when the trigger 300 is pressed at a preset position, the finger pressing the trigger 300 presses on the first trigger button 400, thereby transmitting electrosurgical energy to the end effector 200. Compared with the existing electrosurgical instruments, the electrosurgical instrument provided by the present application can naturally fall on the first trigger button 400 when the operator holds the grip 120, so that it is convenient to press the first trigger button 400 after pressing the trigger 300. By limiting the relative positions of the first trigger button 400 and the trigger 300, the handle 100 has the advantage of intuitive control, which can simplify the operation process to a certain extent. The original action of pressing the trigger can be used for excitation, and then the cutting button is operated independently, which is equivalent to two action processes, and there is no misoperation. The electrosurgical instrument provided by the present application is not only simple to operate and reduces the complexity of the operation, but also reduces the fatigue of the operator during the operation, improves the comfort of control, thereby improving the accuracy of the control, simplifies the workflow, reduces the safety risks caused by misoperation, and improves the efficiency of the operation.
[0048] It should be noted that the area to be treated is the tissue site that requires surgery.
[0049] In some embodiments, the grip portion 120 includes a third side wall 123 connected between the first side wall 121 and the second side wall 122 , and the trigger 300 is located on a side of the third side wall 123 close to the end actuator 200 .
[0050] In some embodiments, Figure 1As shown, the trigger 300 is in an n-shape. The operator's finger can be inserted into the space formed by the n-shaped trigger 300, which is convenient for operating the trigger 300 to rotate relative to the handle 100.
[0051] In some embodiments, Figure 1 As shown, the electrosurgical instrument further includes a rotation knob 800 , one end of the slender shaft 700 is connected to the mounting member 110 via the rotation knob 800 , and the other end is connected to the end effector 200 .
[0052] In some embodiments, Figure 1 As shown, end effector 200 includes an upper jaw member 210 and a lower jaw member 220 , and trigger 300 is movable relative to handle 100 to drive upper jaw member 210 and lower jaw member 220 to move closer to or farther from each other.
[0053] In some embodiments, Figure 1 and Figure 2 As shown, a second excitation button 500 is provided on the second side wall 122, and either the first excitation button 400 or the second excitation button 500 is pressed or both are pressed at the same time to deliver electrosurgical energy to the end effector 200. The second excitation button 500 is provided on the second side wall 122, and when the first excitation button 400 is pressed, or the second excitation button 500 is pressed, or the first excitation button 400 and the second excitation button 500 are pressed at the same time, the electrosurgical energy can be delivered to the end effector 200. The present application provides the second excitation button 500 on the second side wall 122, so that the operator can hold the grip 120 with the left hand or the right hand, thereby improving the convenience of using the electrosurgical instrument.
[0054] It should be noted that if Figure 1 and Figure 2 As shown, a first trigger button 400 is installed on the first side wall 121. When the operator holds the device with the right hand, the operator's palm is attached to the second side wall 122, the middle of the finger holds the trigger 300, and the fingertip can be located at the first trigger button 400. In actual use, after pressing the trigger 300, the first trigger button 400 can be pressed by the fingertip to realize power supply to the end effector 200. When the operator holds the device with the left hand, the operator's palm is attached to the first side wall 121, the middle of the finger holds the trigger 300, and the fingertip can be located at the second trigger button 500. In actual use, after pressing the trigger 300, the second trigger button 500 can be pressed by the fingertip to realize power supply to the end effector 200.
[0055] In some embodiments, Figures 1 to 3As shown, the first excitation button 400 includes a button portion 410 and a trigger portion 420. The button portion 410 and the trigger portion 420 are selectively connected at a single point or multiple points. The button portion 410 is used to respond to the pressing operation of the hand, and the trigger portion 420 is used to communicate with the control system of the electrosurgical surgical instrument. The button portion 410 and the trigger portion 420 are connected at a single point or multiple points. When the button portion 410 is pressed, the trigger portion 420 receives a pressure signal and transmits the signal to the control system of the electrosurgical surgical instrument, and the control system thereby conducts the circuit to transmit electrosurgical energy to the end effector 200.
[0056] In a specific embodiment, the first excitation button 400 is a trigger switch, and the trigger force of the trigger switch is 5N-10N.
[0057] In some embodiments, the second excitation button 500 has the same structure as the first excitation button 400. In some embodiments, the second excitation button 500 has a different structure from the first excitation button 400. For example, the second excitation button 500 is a touch switch.
[0058] When the first trigger button 400 is disposed on the first side wall 121 and the second trigger button 500 is disposed on the second side wall 122, the operator may accidentally touch and press the first trigger button 400 or the second trigger button 500 when holding the grip portion 120. Figure 4 As shown, the outer wall of the first excitation button 400 is concave relative to the first side wall 121, and the outer wall of the second excitation button 500 is concave relative to the second side wall 122. The outer wall of the first excitation button 400 and the outer wall of the second excitation button 500 are concave inwardly to prevent the operator's palm from accidentally touching the outer wall of the first excitation button 400 or the outer wall of the second excitation button 500.
[0059] In a specific embodiment, if Figure 4 As shown, the first side wall 121 is in the shape of a convex curved surface, and the outer wall of the first excitation button 400 is in the shape of a concave curved surface; the second side wall 122 is in the shape of a convex curved surface, and the outer wall of the second excitation button 500 is in the shape of a concave curved surface. The first side wall 121 and the second side wall 122 are both in the shape of a convex curved surface, which is convenient for the operator to hold, while the outer wall of the first excitation button 400 and the outer wall of the second excitation button 500 are both in the shape of a concave curved surface, so that the outer wall of the first excitation button 400 is concave relative to the first side wall 121, and the outer wall of the second excitation button 500 is concave relative to the second side wall 122, so as to prevent the first excitation button 400 or the second excitation button 500 from being accidentally touched.
[0060] In some embodiments, Figure 5 and Figure 6As shown, the outer wall of the first excitation button 400 is convex relative to the first side wall 121, and the outer wall of the second excitation button 500 is convex relative to the second side wall 122. The first excitation button 400 is convex relative to the first side wall 121, and the second excitation button 500 is convex relative to the second side wall 122, which is easy to press.
[0061] In a specific embodiment, the first side wall 121 and the first excitation button 400 are both convex curved surfaces, and the curvature of the first excitation button 400 is greater than the curvature of the first side wall 121, that is, the first excitation button 400 is more convex than the first side wall 121, and when the operator holds the grip 120 with his right hand, it is convenient to press the first excitation button 400.
[0062] In a specific embodiment, the second side wall 122 and the second excitation button 500 are both convex curved surfaces, and the curvature of the second excitation button 500 is greater than the curvature of the second side wall 122, that is, the second excitation button 500 is more convex than the second side wall 122, and when the operator holds the grip 120 with his left hand, it is convenient to press the second excitation button 500.
[0063] The first excitation button 400 is protruding compared to the first side wall 121, and the outer wall of the second excitation button 500 is protruding relative to the second side wall 122. The palm of the hand may accidentally touch and press the first excitation button 400 or the second excitation button 500. Therefore, in some embodiments, the first excitation button 400 and the second excitation button 500 can be pressed at the same time to deliver electrosurgical energy to the end effector 200. Through the program setting of the control system, the control system will only power the end effector 200 when both the first excitation button 400 and the second excitation button 500 are pressed, so that even if the first excitation button 400 or the second excitation button 500 is accidentally touched and pressed alone, electrosurgical energy will not be delivered to the end effector 200.
[0064] In order to prevent the palm from accidentally pressing the first trigger button 400 or the second trigger button 500, in some embodiments, as Figure 5 and Figure 6 As shown, the electrosurgical instrument further includes a limiter 600 mounted on the gripping portion 120, and the limiter 600 has a first state and a second state; when in the first state, the limiter 600 locks the first excitation button 400 to limit the first excitation button 400 from being excited; when in the second state, the limiter 600 locks the second excitation button 500 to limit the second excitation button 500 from being excited. By setting the limiter 600, when the limiter 600 is in the first state, the limiter 600 locks the first excitation button 400, limiting the first excitation button 400 from being pressed for excitation, and when the limiter 600 is in the second state, the limiter 600 locks the second excitation button 500, limiting the second excitation button 500 from being pressed for excitation.
[0065] In a specific embodiment, if Figure 5 and Figure 6 As shown, a slide groove 124 is provided on the outer wall of the grip portion 120 on the side away from the trigger 300, and the limiter 600 is slidably provided in the slide groove 124 to switch between the first state and the second state. By providing the slide groove 124, the limiter 600 is slidably provided in the slide groove 124, and when the limiter 600 is located at one of the two ends of the slide groove 124, the limiter 600 is in the first state, and when the limiter 600 is located at the other end, the limiter 600 is in the second state.
[0066] In a more specific embodiment, Figure 5 and Figure 6 As shown, the slide groove 124 extends along the height direction of the grip portion 120, and the slide groove 124 has a first end and a second end distributed along its length direction, and the second end is located at a side of the first end away from the mounting member 110. When the limiting member 600 is at the second end (such as Figure 5 ), the limiting member 600 abuts against the second excitation button 500, limiting the relative movement of the second excitation button 500 and the gripping portion 120, that is, at this time, only the first excitation button 400 can be pressed, so in the first state, pressing the first excitation button 400 can realize power supply to the end actuator 200. When the limiting member 600 is at the first end (as shown in FIG. Figure 6 As shown in the figure, the limit member 600 abuts against the first excitation button 400, limiting the relative movement between the first excitation button 400 and the holding portion 120, that is, only the second excitation button 500 can be pressed at this time, so in the second state, pressing the second excitation button 500 can realize power supply to the end actuator 200.
[0067] In some embodiments, Figure 1 , Figure 5 and Figure 6 As shown, the first excitation button 400 is in the shape of a strip. The first excitation button 400 is set in the shape of a strip, so that the pressable range of the first excitation button 400 becomes larger, so that when holding it at will, there is always a finger that can touch the first excitation button 400, making the operation and holding more free.
[0068] In a specific embodiment, if Figure 1 As shown, the first excitation button 400 is in a strip shape, and the first excitation button 400 extends along a first direction, wherein the first direction is the height direction of the grip portion 120. The first excitation button 400 is configured as a strip shape, which increases the contact area between the operator's hand and the first excitation button 400, thereby facilitating pressing the first excitation button 400.
[0069] In a specific embodiment, if Figure 4 As shown, a first accommodating groove 1211 in a long strip shape is provided on the first side wall 121, and the first accommodating groove 1211 extends along a first direction, and the first accommodating groove 1211 is used to accommodate the first excitation button 400. The first accommodating groove 1211 is provided to facilitate accommodating the first excitation button 400.
[0070] In a specific embodiment, Figure 2 As shown, the second excitation button 500 is in a strip shape, and the second excitation button 500 extends along the first direction. The second excitation button 500 is set in a strip shape, so that the pressable range of the second excitation button 500 becomes larger, so that when holding it at any time, there is always a finger that can touch the second excitation button 500, making the operation and holding more free.
[0071] In some embodiments, Figure 2 and Figure 4 As shown, a second accommodating groove 1221 in a strip shape is provided on the second side wall 122, and the second accommodating groove 1221 extends along the first direction, and the second accommodating groove 1221 is used to accommodate the second excitation button 500. The second accommodating groove 1221 is provided to facilitate accommodating the second excitation button 500.
[0072] In some embodiments, Figure 7 As shown, a first excitation button 400 is provided on the first side wall 121 , wherein the first side wall 121 is the side wall against which the fingertips of the operator touch when holding the holding portion 120 with the right hand.
[0073] In some embodiments, Figure 8 As shown, a first excitation button 400 is provided on the first side wall 121 , wherein the first side wall 121 is the side wall against which the fingertips of the operator touch when holding the holding portion 120 with his left hand.
[0074] The present application also provides an electrosurgical system, including a host and the above-mentioned electrosurgical instrument, wherein the host is connected to the electrosurgical instrument, and the host is used to provide excitation energy for the electrosurgical instrument and obtain a control or detection signal. The host is connected to the electrosurgical instrument, and the excitation energy provided by the host can be transmitted to the end effector 200 to perform electrocoagulation on the tissue clamped by the end effector 200. Moreover, the host can receive the control signal or detection signal transmitted by the electrosurgical instrument.
[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
