Description

Technical Field

[0002] In existing laparoscopic minimally invasive surgeries, the surgeon needs several different types of instruments to complete the operation, such as passive needle holders for clamping needles and suturing, grasping forceps for grabbing and lifting tissues, and electrosurgical instruments used in conjunction with the main unit of the electrosurgical knife. The instruments contact the surface of the patient's tissues and are used to separate tissues and stop bleeding. Existing electrosurgical instruments are mainly divided into two types: bipolar instruments and monopolar instruments. Bipolar instruments are generally used for electrocoagulation, that is, to coagulate some small bleeding holes. The current is only conducted between the tips of the two forceps, so that the tissue is affected by the thermal effect of the current, while the tissue outside the forceps is not affected, such as bipolar Maryland forceps; monopolar instruments use high-frequency current in a loop to act on the human body to achieve the purpose of cutting and stopping bleeding, such as monopolar electric hooks and electric scissors. Because of the wide variety of instruments required in general laparoscopic surgery, the cost of surgery is high. Summary of the invention

[0048] See also Figure 1 , Figure 2 , Figure 3 and Figure 7 , Figure 1 A schematic diagram of an end effector 10 provided in one embodiment of the present invention; Figure 2 A front view of an end effector 10 provided in one embodiment of the present invention; Figure 3 A schematic diagram of a portion of an insulating seat hidden in an end effector 10 provided in an embodiment of the present invention; Figure 7 A simplified diagram of the connection between the electrode connector and the bipolar connector in the surgical device provided by an embodiment of the present invention and the end effector 10. The end effector 10 provided by an embodiment of the present invention comprises an insulating seat 100, a conductive component 200 and an actuator component 300; the insulating seat 100 comprises two connecting plates 110 arranged opposite to each other and connected to each other; the conductive component 200 comprises two wiring terminals 210, the two wiring terminals 210 are respectively arranged on opposite sides of the two connecting plates 110, and the conductive component 200 is used to electrically connect to at most one of the monopolar connector 400 and the bipolar connector 500; the actuator component 300 is connected to the insulating seat 100, the actuator component 300 is at least partially arranged between the two connecting plates 110, and is electrically connected to both wiring terminals 210, and when the conductive component 200 is used to electrically connect to the monopolar connector 400 or the bipolar connector 500, the actuator component 300 can be electrically conductive.

[0049] Specifically, in the present application, when the conductive component 200 is electrically connected to the bipolar connector 500, the actuator component 300 can act as a bipolar instrument; when the conductive component 200 is electrically connected to the monopolar connector 400, the actuator component 300 can act as a monopolar instrument; when the conductive component 200 is not electrically connected to the monopolar connector 400 or the bipolar connector 500, the actuator component 300 can act as a passive instrument. Therefore, in surgeries requiring a wide variety of surgical instruments, it is only necessary to control the conductive component 200 to realize more than one application scenario of the actuator component 300, thereby reducing costs and improving the adaptability of the end effector 10.

[0050] It should be noted that bipolar instruments generally have two pieces of forceps, one of which is electrically connected to the positive pole of the power supply, and the other is electrically connected to the negative pole of the power supply. When the jaws contact the tissue and close, a path is formed between the instrument and the tissue, and a high-frequency current passes through the tissue to complete the coagulation of the blood vessels or bleeding points. Monopolar instruments can be electric shears, electric forceps, electric hooks, etc. Monopolar instruments are electrically connected to the positive pole of the power supply. When the instrument contacts the tissue with a negative plate or grounded, a path is formed between the instrument and the tissue, and a high-frequency current acts on the target object, thereby achieving the purpose of cutting and hemostasis. Passive instruments are used for clamping needles and suturing, and grasping forceps are used to grasp and pull tissues, etc.

[0051] See also Figure 2 and Figure 3 In one embodiment, the conductive component 200 further includes two conductive sheets 220 and two conductive wires 230; the two conductive sheets 220 are respectively mounted on two connecting plates 110, the two conductive sheets 220 are respectively abutted against and electrically connected to the actuator component 300, and the portions where the two conductive sheets 220 abut against the actuator component 300 are constructed as two terminal terminals 210; one ends of the two conductive wires 230 are respectively electrically connected to the two conductive sheets 220, and the other ends are respectively used to be electrically connected to the bipolar connector 500, or the other end of one of the two conductive wires 230 is used to be electrically connected to the monopolar connector 400.

[0052] Specifically, the portions where the two conductive sheets 220 abut against the actuator assembly 300 are configured as two terminals 210, so that the actuator assembly 300 and the two conductive sheets 220 are always electrically connected. When the two wires 230 are respectively used to electrically connect to the bipolar connector 500, that is, one wire 230 is electrically connected to the positive pole of the power supply, and the other wire 230 is connected to the negative pole of the power supply, so that the two terminals 210 carry opposite charges, the actuator assembly 300 abutting against the terminals 210 on both sides can be electrically conductive. When one of the two wires 230 is electrically connected to the monopolar connector 400, that is, one of the two wires 230 is connected to the positive pole of the power supply, so that one terminal 210 is charged, when the actuator assembly 300 is in contact with a tissue equipped with a negative plate or grounded, the actuator assembly 300 abutting against the terminals 210 on both sides can be electrically conductive. Preferably, the conductive sheet 220 is a conductive metal sheet.

[0053] Furthermore, the conductive sheet 220 is a conductive spring sheet, so that the conductive sheet 220 is always stably in contact with both sides of the actuator assembly 300 under the action of its own elastic force, thereby improving the reliability of the end effector 10.

[0054] Furthermore, the insulating seat 100 further includes a matching plate 130, and both ends of the matching plate 130 are respectively connected to the two connecting plates 110, so that the two connecting plates 110 are stably connected. The matching plate 130 is provided with two mounting holes 131, and the two mounting holes 131 are arranged at intervals along the arrangement direction of the two connecting plates 110. The two mounting holes 131 are used for two wires 230 to pass through, so that the wires 230 are limited, so as to prevent the two wires 230 from being entangled when the actuator assembly 300 is in operation.

[0055] See also Figure 4 and Figure 5 , Figure 4 A schematic diagram of the cooperation between the conductive component and the insulating seat in the end effector 10 provided in one embodiment of the present invention; Figure 5 The left side view of the conductive component and the insulating seat in the end effector 10 provided in one embodiment of the present invention. In one embodiment, the two connecting plates 110 are provided with a fixing groove 111 on the opposite side, and the two conductive sheets 220 are respectively installed in the two fixing grooves 111; the insulating seat 100 also includes two limiting plates 120, which are respectively connected to the two connecting plates 110 and cover the corresponding parts of the fixing grooves 111.

[0056] Specifically, the conductive sheet 220 is installed in the fixed groove 111 and abuts against the groove wall of the fixed groove 111. The groove wall of the fixed groove 111 can limit the movement of the conductive sheet 220 on the connecting plate 110, and each limiting plate 120 covers a portion of the corresponding fixed groove 111, thereby limiting the corresponding conductive sheet 220 from escaping, so that the conductive sheet 220 is stably limited at the current position, so that each conductive sheet 220 is stably abutted against the actuator assembly 300.

[0057] See also Figure 4 In one embodiment, the limiting plate 120 is disposed at one end of the corresponding fixing slot 111 close to the wire 230, and each limiting plate 120 is provided with a through hole 121 connected to the corresponding fixing slot 111 for the corresponding wire 230 to pass through.

[0058] Specifically, by setting the through hole 121, the connection between the wire 230 and the conductive sheet 220 is located in the fixing groove 111, thereby protecting the connection between the wire 230 and the conductive sheet 220, so that the wire 230 is stably connected to the corresponding conductive sheet 220, thereby improving the reliability of the end effector 10.

[0059] Furthermore, the two limiting plates 120 are installed on a side of the insulating base 100 away from the actuator assembly 300 , thereby reducing the interference of the limiting plates 120 on the actuator assembly 300 .

[0060] See also Figure 3 and Figure 6 , Figure 6 A schematic diagram of an actuator assembly 300 in an end effector 10 provided in an embodiment of the present invention. In one embodiment, the actuator assembly 300 includes an operating member 310 and an insulating plate 320, the insulating plate 320 is connected to the insulating seat 100, the operating member 310 and the insulating plate 320 are detachably connected, and the operating member 310 is used to be electrically connected to the terminal 210, so that during surgery, the corresponding operating member 310 can be conveniently replaced according to specific needs, thereby further reducing the cost of surgery and the adaptability of the end effector 10.

[0061] See also Figure 3 and Figure 6 In one embodiment, one of the operating member 310 and the insulating plate 320 is provided with a positioning groove 321, and the other is provided with a positioning block 311. The positioning block 311 is plugged into the positioning groove 321, so that the operating member 310 and the corresponding insulating plate 320 can be easily disassembled and stably connected, thereby improving the stability of the end effector 10.

[0062] See also Figure 6In one embodiment, a positioning groove 321 is disposed on one side of the insulating plate 320, the positioning groove 321 includes at least two intersecting mounting grooves, a positioning block 311 is disposed on the operating member 310, and the positioning block 311 includes mounting blocks corresponding to each mounting groove, each mounting block is plugged into and matched with the corresponding mounting groove to limit the movement of the operating member 310 on the insulating plate 320.

[0063] Specifically, each mounting block is installed in a corresponding mounting groove, and the groove wall of each mounting groove can limit the movement of the corresponding mounting block on the insulating plate 320. Since at least two mounting grooves intersect, the groove wall of each mounting groove can apply force along its own two directions on the insulating plate 320 to the positioning block 311, thereby stably limiting the movement of the operating member 310 on the insulating plate 320.

[0064] Furthermore, the positioning block 311 also includes a connecting block 312, which is at least partially located outside the insulating plate 320 and is connected to one end of the operating member 310 away from the wire 230, and the two ends of the connecting block 312 are respectively connected to two intersecting and connected mounting blocks, thereby being able to provide a stable limiting force to both ends of the operating member 310 close to the insulating seat 100, so that the operating member 310 is stably connected to the corresponding insulating seat 100.

[0065] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, when the conductive component 200 is used to electrically connect with the bipolar connector 500, the number of the operating member 310 and the number of the insulating plates 320 are both two, the two insulating plates 320 are arranged opposite to each other along the arrangement direction of the two connecting plates 110, and the two positioning grooves 321 are respectively arranged on the sides of the two insulating plates 320 that are away from each other.

[0066] Specifically, when the wire 230 assembly is electrically connected to the bipolar connector 500, the two insulating plates 320 are connected to operating members 310, the positioning blocks 311 on the two operating members 310 are inserted into the corresponding positioning grooves 321, and the two positioning blocks 311 are respectively abutted against the two conductive sheets 220, so that each operating member 310 can be stably electrically connected to the two conductive sheets 220 while being stably connected to the corresponding insulating plate 320.

[0067] When the wire 230 assembly is electrically connected to the monopolar connector 400, at least one of the two insulating plates 320 is connected to an operating member 310. The conductive sheet 220 connected to the monopolar connector 400 through the wire 230 abuts against an operating member 310. When the operating member 310 contacts a target object with a negative plate or a ground, the current flowing through the operating member 310 can form a loop.

[0068] Furthermore, if there are two insulating plates 320, the type and number of the operating members 310 can be changed according to specific requirements to improve the adaptability of the end effector 10. In other embodiments, there can also be one insulating plate 320.

[0069] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the two positioning grooves 321 are staggered in the arrangement direction of the two connecting plates 110 .

[0070] Specifically, when the wire 230 assembly is electrically connected to the bipolar connector 500, both operating members 310 are charged, so the problem of electrical clearance and creepage distance between two adjacent conductors must be considered. Since the two positioning grooves 321 are staggered in the arrangement direction of the two connecting plates 110, when the two operating members 310 are installed on the corresponding insulating plates 320, the two positioning blocks 311 can also be staggered in the arrangement direction of the two connecting plates 110, thereby increasing the distance between the two positioning blocks 311, that is, increasing the electrical clearance and creepage distance between the two operating members 310, avoiding the problem of current short circuit, thereby improving the reliability of the end effector 10.

[0071] The overall length of the end effector 10 is relatively large, which results in a large turning radius of the end effector 10 and lacks flexibility in application scenarios in narrow spaces. Therefore, in order to reduce the overall length of the end effector 10, the embodiment of this specification improves the above end effector 10.

[0072] See also Figure 1-Figure 6 In one embodiment, the end effector 10 further includes a driving wheel 600 disposed on the insulating seat 100, wherein the actuator assembly 300 and the insulating seat 100 cooperate to form a rotation center 140, and the actuator assembly 300 can rotate around the rotation center 140 through the driving mating portion 150. The driving mating portion 150 is formed between the actuator assembly 300 and the driving wheel 600. When the driving wheel 600 rotates, the driving wheel 600 can drive the actuator assembly 300 to switch between the first state and the second state relative to the insulating seat 100.

[0073] The first state refers to that the actuator assembly 300 is in a relatively open state, as shown in the figure. The second state refers to that the actuator assembly 300 is in a closed state, as shown in the figure.

[0074] See also Figure 1-Figure 6In one embodiment, at the rotation center 140 , the actuator assembly 300 may be provided with a first protrusion 322 , and the first protrusion 322 forms a rotation axis of the actuator assembly 300 . In some embodiments, the insulating seat 100 may be provided with a first recess 113 that cooperates with the first protrusion 322 .

[0075] See also Figure 1-Figure 6 In one embodiment, at the rotation center 140, the actuator assembly 300 may be provided with a first recessed portion 113, and the insulating seat 100 may be provided with a first protrusion 322 that cooperates with the first recessed portion 113. When the first protrusion 322 is located in the first recessed portion 113, the first protrusion 322 and the first recessed portion 113 cooperate to form the rotation center 140, and the actuator assembly 300 can rotate around the rotation center 140.

[0076] In some alternative embodiments, at the rotation center 140 , a first recessed portion 113 may be provided on the actuator assembly 300 , and a first protruding portion 322 cooperating with the first recessed portion 113 may be provided on the insulating seat 100 .

[0077] See also Figure 1-Figure 6 In one embodiment, the first recessed portion 113 may be a countersunk hole or a through hole 121. In some embodiments, the first recessed portion 113 may be a circular hole. In some embodiments, the first recessed portion 113 may be a partial circular hole with a central angle less than 360°.

[0078] See also Figure 1-Figure 6 In one embodiment, the driving engagement portion 150 may include a second protrusion 610 disposed on the driving wheel 600 and a second recess 324 disposed on the actuator assembly 300 .

[0079] In some alternative embodiments, the driving engagement portion 150 may include a second protrusion 610 disposed on the actuator assembly 300 , and a second recess 324 disposed on the driving wheel 600 .

[0080] When the second protrusion 610 is located in the second recess 324, the second protrusion 610 and the second recess 324 cooperate to form the driving engagement portion 150. When the driving wheel 600 rotates, the actuator assembly 300 can be driven to rotate around the rotation center 140 through the driving engagement portion 150.

[0081] See also Figure 1-Figure 6In one embodiment, the second protrusion 610 can be disposed at the outer edge of the driving wheel 600. The outer edge is a position on the driving wheel 600 close to the edge, which can refer to a position outside the edge of the driving wheel 600, a position inside the edge of the driving wheel 600, or a position at the edge of the driving wheel 600. Specifically, the second protrusion 610 can be completely outside the edge of the driving wheel 600, completely inside the edge of the driving wheel 600, or partially outside the edge of the driving wheel 600 and partially inside the edge of the driving wheel 600. In some embodiments, the second protrusion 610 can be disposed at any position within the outer edge of the driving wheel 600. In some embodiments, the second recess 324 can be disposed at a position on the actuator assembly 300 away from the rotation center 140, for example, at an edge of the actuator assembly 300 away from the rotation center 140. The farther the second protrusion 610 and / or the second recess 324 are from the rotation center 140, the smaller the force of the driving wheel 600 to drive the actuator assembly 300 to rotate can be.

[0082] See also Figure 1-Figure 6 In one embodiment, the actuator assembly 300 may include a limiting groove 323, and the limiting groove 323 is used to cooperate with the limiting protrusion 620 on the driving wheel 600. Through the cooperation between the limiting groove 323 and the limiting protrusion 620, the actuator assembly 300 can be limited to rotate around the rotation center 140. In some embodiments, the limiting groove 323 is concentric with the rotation center 140, as shown in the figure. In some embodiments, the distance between the limiting groove 323 and the first protrusion 322 is equal to the distance between the limiting protrusion 620 and the first recessed portion 113.

[0083] In one embodiment, the limiting groove 323 may be a closed limiting groove 323 , that is, both ends of the limiting groove 323 are closed, so as to limit the moving stroke of the limiting protrusion 620 in the groove.

[0084] In one embodiment, the limiting groove 323 may be an open limiting groove 323 , that is, one end of the limiting groove 323 is open and the other end is closed, and the limiting protrusion 620 may move outside the limiting groove 323 during the rotation of the actuator assembly 300 around the rotation center 140 .

[0085] In some of the aforementioned embodiments, the limiting groove 323 is designed as an open limiting groove 323, and the first protrusion 322 of the actuator assembly 300 can be withdrawn from the first recessed portion 113 on the insulating seat 100 when the limiting protrusion 620 moves out of the limiting groove 323, so that the actuator assembly 300 can be easily removed.

[0086] See also Figure 1-Figure 6In one embodiment, the driving wheel 600 can be connected to the insulating seat 100 through a pin, and the driving wheel 600 rotates around the pin as the central axis. In some embodiments, the pin can be used as a limiting protrusion 620. In some embodiments, the insulating seat 100 is provided with an axial hole 112, and the driving wheel 600 can be connected to the insulating seat 100 by inserting the pin into the axial hole 112.

[0087] When the limit groove 323 is an arc groove, the corresponding arc should meet the opening and closing angle requirements of the actuator assembly 300, that is, when the pin moves from one end to the other end in the limit groove 323, the actuator assembly 300 can switch between a closed state and a state opened to the maximum working angle.

[0088] In some alternative embodiments, the pin and the limiting protrusion 620 can be two different components, and accordingly, a rotation groove corresponding to the pin needs to be provided on the actuator assembly 300. In some embodiments, the rotation groove can be a closed rotation groove or an open rotation groove. The structure of the rotation groove is similar to that of the aforementioned limiting groove 323, and reference can be made to the aforementioned description of the limiting groove 323.

[0089] See also Figure 2 , Figure 3 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 , Figure 8 This is a first schematic diagram of the cooperation between the traction wire and the driving wheel in the end effector provided by one embodiment of the present invention. Fig. 9 This is a second schematic diagram of the cooperation between the traction wire and the driving wheel in the end effector provided by one embodiment of the present invention. Fig.10 A third schematic diagram of the cooperation between the traction wire and the driving wheel in the end effector provided by one embodiment of the present invention. In one embodiment, the end effector 10 may include a traction wire 160. The traction wire 160 is used to control the rotation of the driving wheel 600. Specifically, the traction wire 160 can control the driving wheel 600 to rotate clockwise or counterclockwise.

[0090] Furthermore, the driving wheel 600 includes a first driving wheel 630 and a second driving wheel 640 which can rotate independently relative to each other.

[0091] Furthermore, a third recess 650 may be provided on the driving wheel 600. In some embodiments, the traction line 160 is connected to a traction block 161. The third recess 650 is used to accommodate the traction block 161, and the traction block 161 is used to stably and reliably transmit the rotational force of the traction line 160 to the driving wheel 600 in the third recess 650.

[0092] It is worth noting that the position where the traction line 160 transmits the rotational force to the driving wheel 600 includes but is not limited to the third recessed portion 650. For example, a wire groove may be provided on the driving wheel 600, and the traction line 160 is wound in the wire groove. When the traction line 160 is pulled, the rotational force may also be transmitted to the driving wheel 600 through the static friction between the traction line 160 and the wire groove.

[0093] See also Figure 3 , Figure 8 , Fig. 9 and Fig.10 In one embodiment, the traction line 160 may include a first line body 162 and a second line body 163 , wherein the first line body 162 is used to drive the first driving wheel 630 , and the second line body 163 is used to drive the second driving wheel 640 .

[0094] Furthermore, there may be two traction blocks 161 , which are respectively disposed on the first wire body 162 and the second wire body 163 .

[0095] Furthermore, at least a portion of the first wire body 162 may be wound around the first driving wheel 630 along the first direction, and at least a portion of the second wire body 163 may be wound around the second driving wheel 640 along the second direction.

[0096] The first direction may refer to a clockwise direction or a counterclockwise direction. The second direction may refer to a clockwise direction or a counterclockwise direction. In some embodiments, the first direction and the second direction are opposite directions. For example, if the first direction is a clockwise direction, the second direction is a counterclockwise direction. Fig.10 In some of the above embodiments, the first wire 162 and the second wire 163 are wound in different directions on two first driving wheels 630 and second driving wheels 640 that can rotate independently of each other, so that the actuator assembly 300 can be opened and closed by driving the traction wire 160 .

[0097] In addition, the first wire body 162 and the first driving wheel 630 can be fixed by setting the traction block 161 in the third recessed portion 650, and the second wire body 163 and the second driving wheel 640 can be fixed by setting the traction block 161 in the third recessed portion 650, as shown in the figure.

[0098] See also Figure 2 , Figure 3 , Figure 6 , Figure 8 , Fig. 9 and Fig.10In one embodiment, the driving wheel 600 can be a wheel, and the driving wheel 600 is pulled by a traction line 160, so that one jaw of the actuator assembly 300 can always keep a fixed position, and the other jaw of the actuator assembly 300 can be driven to rotate by the traction line 160 through the driving wheel 600.

[0099] In some of the aforementioned embodiments, the driving wheel 600 can convert the traction motion of the traction line 160 into a rotational motion and then directly drive the actuator assembly 300 without the need for other intermediate components, thereby achieving high transmission efficiency.

[0100] In one of the embodiments, when the actuator assembly 300 needs to be replaced, the actuator assembly 300 can be driven to open an angle larger than the designed opening and closing angle so that the pin shaft and the limit groove 323 are no longer in contact. In the state shown in the figure, the actuator assembly 300 can be removed from the first recessed portion 113 of the insulating seat 100.

[0101] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 , Fig.11 and Fig.12 , Fig.11 A schematic diagram of a surgical instrument provided according to an embodiment of the present invention. Fig.12 A partial schematic diagram of a surgical instrument provided in one embodiment of the present invention. One embodiment of the present invention further provides a surgical instrument 10, comprising an instrument joint 10 and the above-mentioned end effector 10, wherein the instrument joint 700 is connected to the insulating seat 100, and the instrument joint 700 is used to drive the actuator assembly 300 to move.

[0102] Specifically, the instrument joint 700 can be used to drive the end effector 10 to move (for example, yaw or rotation). As an exemplary illustration, the instrument joint 700 can be similar to a snake bone structure, and the distal end of the instrument joint 700 can be connected to the proximal end of the insulating seat 100, and the end effector 10 can be driven to perform yaw or rotation by bending the instrument joint 700 or rotating around its own axis. The distal end refers to the end away from the operator when the surgical instrument is used, and the proximal end refers to the end close to the operator when the surgical instrument is used.

[0103] In this embodiment, when the conductive component 200 is electrically connected to the bipolar connector 500, the actuator component 300 can act as a bipolar instrument; when the conductive component 200 is electrically connected to the monopolar connector 400, the actuator component 300 can act as a monopolar instrument; when the conductive component 200 is not electrically connected to the monopolar connector 400 or the bipolar connector 500, the actuator component 300 can act as a passive instrument. Therefore, in surgeries requiring a wide variety of surgical instruments, more than one application scenario of the actuator component 300 can be realized by only controlling the conductive component 200, thereby reducing costs and improving the adaptability of surgical instruments.

[0104] See also Fig.11 and Fig.12 In one embodiment, the surgical instrument further includes an operating handle 800, which can at least be used to control the driving wheel 600 of the end effector 10 and the actuator assembly 300 to switch between the first state and the second state, thereby enabling the actuator assembly 300 to perform an opening and closing action.

[0105] See also Figure 8-Figure 12 In one embodiment, the operating handle 800 can control the driving wheel 600 to rotate in the first direction or the second direction through the traction line 160, so that the actuator assembly 300 switches between the first state and the second state. As an exemplary illustration, the operating handle 800 includes a handle housing 810, a grip 820, a driving gear 830, a driven gear 840, a first reel 850, a second reel 860, a winding wheel 870, a transmission rope assembly 880 and a handle trigger 890. Among them, the transmission rope assembly 880 includes a rope body and a rope loop covering the rope body. Among them, the handle trigger 890 is connected to the driving gear 830, the driving gear 830 is meshed with the driven gear 840, the driven gear 840 is coaxial with the first reel 850, and the rope body of the transmission rope assembly 880 is wound around the first reel 850 and the second reel 860. In some embodiments, the rope bodies may cross each other. In some embodiments, the rope bodies may not cross. The winding wheel 870 is coaxial with the second wire wheel 860, the other ends of the first wire body 162 and the second wire body 163 in the traction wire 160 are fixed on the winding wheel 870, and at least parts of the first wire body 162 and the second wire body 163 are wound on the winding wheel 870 in opposite directions.

[0106] When the operator wants to control the actuator assembly 300 in the end effector 10 to open and close through the operating handle 800, the operator can tighten or loosen the handle trigger 890 to drive the active gear 830 to rotate. The rotation of the active gear 830 can be transmitted to the driven gear 840 through gear meshing, so that the first wire wheel 850 rotates under the drive of the driven gear 840. The rotation of the first wire wheel 850 can be transmitted to the second wire wheel 860 through the rope body, so that the winding wheel 870 can rotate under the drive of the second wire wheel 860, thereby pulling the first wire body 162 and / or the second wire body 163, so that the first drive wheel 630 and / or the second drive wheel 640 rotate, so as to realize the switching of the actuator assembly 300 between the first state and the second state, and achieve the purpose of controlling the actuator assembly 300 to open and close. In some embodiments, the operating handle 800 can also be used to control the instrument joint 700 to bend or rotate, thereby driving the end effector 10 to perform yaw or rotation.

[0107] See also Figure 11-Figure 14 , Fig.13 A schematic diagram of replacing an excitation member in a surgical instrument provided in one embodiment of the present invention. Fig.14 Schematic diagram of a replacement trigger member of a surgical instrument provided in an embodiment of the present invention in an unactivated state and an activated state. In one embodiment, the operating handle 800 may include a handle housing 810, a handle trigger 890, and a replacement trigger member 900 disposed on the handle housing 810.

[0108] See also Figure 11-Figure 14 In one embodiment, the replacement trigger member 900 is located at the end of the travel range of the handle trigger 890. The replacement trigger member 900 can be operated between a first position and a second position. For example, when the operator presses the replacement trigger member 900, the replacement trigger member 900 is in the second position, and when the operator releases the pressure on the replacement trigger member 900, the replacement trigger member 900 can be automatically reset under the action of the reset spring and is in the first position.

[0109] When the replacement trigger member 900 is in the first position, as shown in the left half of the figure, the handle trigger 890 can move within a specified stroke. The movement stroke of the handle trigger 890 corresponds to the rotation angle of the actuator assembly 300. When the handle trigger 890 moves from the starting point of the specified stroke to the end point, the actuator assembly 300 can be driven by the drive wheel 600 to switch from a fully open state to a closed state. Similarly, when the handle trigger 890 moves from the end point of the specified stroke to the starting point, the actuator assembly 300 can be driven by the drive wheel 600 to switch from a closed state to a fully open state.

[0110] See also Figure 11-Figure 14In one embodiment, the operator can move the handle trigger 890 from the starting point to the end point or any position between the starting point and the end point by tightly gripping the handle trigger 890. In some embodiments, after the operator releases the handle trigger 890, the handle trigger 890 automatically returns to the starting point under the action of a return spring disposed between the handle trigger 890 and the grip 820.

[0111] In one embodiment, when the handle trigger 890 moves, it can drive the actuator assembly 300 to perform an opening and closing action.

[0112] When the replacement trigger 900 is in the second position, as shown in the right half of the figure, the handle trigger 890 can move outside the specified stroke. After the handle trigger 890 moves outside the specified stroke, it can drive the actuator assembly 300 to open an angle larger than the designed opening and closing angle, so that the pin shaft and the limit groove 323 are no longer in contact, as shown in the figure. At this time, the jaws of the actuator assembly 300 can fall off, and the operator can remove the actuator assembly 300 from the first recessed portion 113 of the insulating seat 100.

[0113] See also Figure 11-Figure 14 In one embodiment, the replacement trigger member 900 has a first radius when in the first position, and has a second radius when in the second position, and the second radius is smaller than the first radius. In some embodiments, the replacement trigger member 900 may include a main body 920 and a boss 910 disposed on the main body 920. Among them, the main body 920 has a second radius, and the boss 910 has a first radius. The replacement trigger member 900 has a first radius when in the first position, that is, the boss 910 can limit the movement of the handle trigger 890. The replacement trigger member 900 has a second radius when in the second position, that is, the main body 920 can limit the movement of the handle trigger 890. The second radius is smaller than the first radius, so that when the replacement trigger member 900 is in the second position, the handle trigger 890 can drive the actuator assembly 300 to open a larger angle, thereby realizing the detachable control of the actuator assembly 300.

[0114] See also Figure 1 , Figure 2 , Figure 3 and Figure 7 An embodiment of the present invention further provides a surgical device, including a negative plate, a monopolar connector 400, a bipolar connector 500 and the above-mentioned end effector 10, wherein the negative plate is used to be installed on the target object, the bipolar connector 500 is used to be electrically connected to two terminals 210, and the monopolar connector 400 is used to be electrically connected to one terminal 210; the negative plate is used to cooperate with the monopolar connector 400 to make the actuator component 300 electrically conductive when the conductive component 200 is electrically connected to the monopolar connector 400.

[0115] In this embodiment, when the conductive component 200 is electrically connected to the bipolar connector 500, the actuator component 300 can act as a bipolar instrument; when the conductive component 200 is electrically connected to the monopolar connector 400, the actuator component 300 can act as a monopolar instrument; when the conductive component 200 is not electrically connected to the monopolar connector 400 or the bipolar connector 500, the actuator component 300 can act as a passive instrument. Therefore, in surgeries requiring a wide variety of surgical instruments, more than one application scenario of the actuator component 300 can be realized by only controlling the conductive component 200, thereby reducing costs and improving the adaptability of surgical equipment.

[0116] See also Figure 11-Figure 15 The embodiment of the present invention also provides a method for disassembling the actuator assembly 300 of the end effector 10: the operator operates the replacement trigger member 900 to switch the replacement trigger member 900 from the first position to the second position; the operator grips the handle trigger 890 to rotate the drive wheel 600, driving the actuator assembly 300 to open, so that the limiting protrusion 620 is disengaged from the limiting groove 323; the actuator assembly 300 is moved in a direction away from the drive mating portion 150, thereby removing the actuator assembly 300.

[0117] See also Figure 11-Figure 15 The embodiment of the present invention also provides an installation method for the actuator assembly 300 of the end effector 10, as shown in the figure: place the actuator assembly 300 in the replacement tool 930, and align the replacement tool 930 with the driving wheel 600 and insert it into the insulating seat 100; press the pressing parts 940 on both sides of the replacement tool 930 to make the second protrusion 610 on the driving wheel 600 dock with the second recess 324 of the actuator assembly 300; press the replacement trigger 900, at this time, the handle trigger 890 moves to the outside of the specified stroke under the action of the spring in the grip 820, thereby driving the driving wheel 600 to rotate, and at the same time, press the replacement tool 930 to make the actuator assembly 300 open an angle, so that the first protrusion 322 is stuck in the first recess 113; hold the handle trigger 890 tightly to close the actuator assembly 300; remove the replacement tool 930.

[0118] The beneficial effects that may be brought about by the aforementioned embodiments of this specification include but are not limited to: since the actuator assembly 300 is directly driven to rotate by the driving wheel 600 without an intermediate transmission part, the structure is simple and compact, so that the overall length dimension of the end effector 10 can be small, the turning radius is small, and it has good flexibility in the application scenario in a narrow space; by designing the driving matching part 150 at the edge position of the driving wheel 600, it can be ensured that the driving force required for the driving wheel 600 to rotate when the actuator assembly 300 completes the opening and closing action is small, which is conducive to reducing the burden on the operator; the opening and closing control of the actuator assembly 300 can be achieved only by rotating the driving wheel 600, and the actuator assembly 300 can not only have a large opening and closing angle, but also enable the end effector 10 to meet the requirements of some surgical instruments for bilateral opening and closing control through single-rope drive (that is, one or two driving wheels 600 are driven to rotate by a traction line 160); through the open limit groove 323 on the actuator assembly 300 and the partially circular hole-type first recessed portion 113 on the insulating seat 100, the actuator assembly 300 can be easily disassembled and replaced.

[0119] 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.

[0120] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
