Description

Technical Field

[0001] This manual relates to the field of medical devices, and in particular to a cleaning mechanism and surgical instruments. Background Technology

[0002] Surgical robots, due to their high precision and stability, have been applied to minimally invasive surgeries in various fields such as urology, gynecology, and neurosurgery. After surgery, the internal parts of the surgical instruments held by the robot become contaminated. To enable multiple uses of the instruments and ensure their safety, thorough cleaning is necessary after each use. However, the complex internal structure of surgical instruments, with their long and narrow internal channels, makes cleaning difficult. Currently, a common method is to use a flexible tube to flush the instrument's interior. This method is inefficient and inconvenient, requiring medical staff to hold the instrument and failing to achieve high-quality water flow and pressure delivery.

[0003] Therefore, it is desirable to provide a cleaning mechanism and surgical instruments that make it convenient and efficient for medical staff to clean surgical instruments. Summary of the Invention

[0027] This specification relates to a cleaning mechanism and a surgical instrument.

See also... Figures 1-3 , Figure 5 and Figure 6 The following embodiments are for your understanding, but the accompanying drawings are only illustrative of some of the embodiments and do not constitute a limitation on the embodiments.

[0030] like Figure 1 As shown, in some embodiments, a cleaning mechanism 100 may include a receiving groove 110, a pressing structure 120, and a button 130. One end of the receiving groove 110 is capable of receiving a water inlet pipe 200. The receiving groove 110 includes a side wall 111 and an opening 112 opposite to the side wall 111. The pressing structure 120 includes a pressing member 121 and an elastic member 122; the pressing member 121 is disposed outside the opening 112, and the elastic member 122 is compressed and disposed on the side of the pressing member 121 facing away from the opening 112; one end of the elastic member 122 abuts against the pressing member 121, and the other end of the elastic member 122 is fixedly disposed; the pressing member 121, under the elastic force of the elastic member 122, cooperates with the side wall 111 of the receiving groove 110 to press the water inlet pipe 200. The button 130 is connected to the pressing member 121. When the button 130 is pressed, the pressing member 121 moves away from the opening 112, causing the elastic member 122 to be further compressed.

[0031] The receiving groove 110 is a component for accommodating the water inlet pipe 200, and its length direction is parallel to the axial direction of the water inlet pipe 200. In some embodiments, when the cleaning mechanism 100 is used for surgical instruments, the receiving groove 110 may be a component integrally formed on the housing 300 of the surgical instrument. In some embodiments, when the cleaning mechanism 100 is used for surgical instruments, the receiving groove 110 may also be a component connected to the housing 300 of the surgical instrument. Further description of the housing 300 of the surgical instrument is provided below.

[0032] In some embodiments, one end of the receiving tank 110 can receive a water inlet pipe 200, and the other end can receive a cleaning pipe 150. The water inlet pipe 200 and the cleaning pipe 150 cooperate to allow water to flow from the water inlet pipe 200 into the cleaning pipe 150. Further description of the cleaning pipe 150 is provided below.

[0033] In some embodiments, one end of the receiving tank 110 can receive the water inlet pipe 200, while the other end may not be connected to the cleaning pipe 150. The water inlet pipe 200 cooperates with the receiving tank 110 so that water can flow from the water inlet pipe 200 into the space where the receiving tank 110 is located for rinsing. For example, when the cleaning mechanism 100 is used for surgical instruments and the receiving tank 110 is located inside the housing 300 of the surgical instrument, water can flow from the water inlet pipe 200 into the housing 300 of the surgical instrument for rinsing.

[0034] In some embodiments, the receiving groove 110 includes a sidewall 111 and an opening 112 opposite to the sidewall 111.

[0035] Sidewall 111 refers to the portion of receiving groove 110 used to enclose water inlet pipe 200. Sidewall 111 can be in direct contact with water inlet pipe 200. The shape of sidewall 111 conforms to the pipe shape of water inlet pipe 200. For example, sidewall 111 can be a semi-cylindrical wall with a certain thickness.

[0036] Opening 112 refers to the space used to accommodate clamping member 121. The length of opening 112 (i.e., the length along the length direction of receiving groove 110) is greater than or equal to the length of clamping member 121. When water inlet pipe 200 is inserted into receiving groove 110, side wall 111 contacts water inlet pipe 200 at a certain distance. When clamping member 121 and receiving groove 110 cooperate to clamp water inlet pipe 200, clamping member 121 presses against opening 112 and abuts against water inlet pipe 200. Clamping member 121 applies force towards receiving groove 110 to water inlet pipe 200, pressing water inlet pipe 200 into receiving groove 110. The water inlet pipe 200 is clamped by the friction between receiving groove 110 and clamping member 121 and water inlet pipe 200.

[0037] In some embodiments, the sidewall 111 of the receiving groove 110 includes a second cylindrical surface 1111, the axis of which is parallel to the length direction of the receiving groove 110.

[0038] The second cylindrical surface 1111 is the wall surface on the side wall 111 that is in contact with the water inlet pipe 200.

[0039] In some embodiments, the diameter of the radial section (the section perpendicular to the axis of the second cylindrical surface 1111) of the second cylindrical surface 1111 can be equal to or slightly larger than the outer diameter of the water inlet pipe 200, so that the second cylindrical surface 1111 can just surround the water inlet pipe 200. By setting the second cylindrical surface 1111, the receiving groove 110 can fit as close as possible to the outer surface of the water inlet pipe 200, thereby limiting the water inlet pipe 200.

[0040] In some embodiments, the arc angle of the radial section of the second cylindrical surface 1111 can be 180°, which maximizes the contact area without affecting the pressing of the water inlet pipe 200 into the second cylindrical surface 1111, allowing the water inlet pipe 200 to withstand greater pressure within an acceptable deformation range, thereby clamping the water inlet pipe 200 more tightly. In some embodiments, the arc angle of the radial section of the second cylindrical surface 1111 can also be any angle, and the arc angle of the radial section of the second cylindrical surface 1111 can be set according to actual needs. This specification does not limit the arc angle of the radial section of the second cylindrical surface 1111 in any way.

[0041] By setting the second cylindrical surface 1111 on the side wall 111 to match the water inlet pipe 200, the water inlet pipe 200 can be positioned, thus improving stability.

[0042] The clamping structure 120 is a component used to fix and clamp the water inlet pipe 200.

[0043] In some embodiments, the clamping structure 120 may include a clamping member 121 and an elastic member 122.

[0044] The elastic element 122 is a component that applies pressure toward the inlet pipe 200 to the clamping element 121. In some embodiments, the elastic element 122 and the opening 112 are located on opposite sides of the clamping element 121, with one end of the elastic element 122 (e.g., the telescopic end) abutting against the clamping element 121, and the other end of the elastic element 122 (e.g., the fixed end) fixedly disposed. The telescopic end of the elastic element 122 refers to the end that generates displacement during the telescopic process, and the fixed end of the elastic element 122 refers to the end that remains unchanged during the telescopic process. In some embodiments, when the cleaning mechanism is applied to surgical instruments, the fixed end of the elastic element 122 can be fixedly disposed on the housing 300.

[0045] The elastic element 122 can be compressed under the control of the button 130. When the button 130 is pressed, causing the elastic element 122 to be compressed, the clamping member 121 is lifted, releasing the water inlet pipe 200. When the button 130 is released, the elastic force of the elastic element 122 applies a spring force toward the clamping member 121, thereby clamping the water inlet pipe 200 by the clamping member 121.

[0046] In some embodiments, the elastic element 122 may be in various forms such as a helical spring, a gas spring, or elastic rubber, and this specification does not limit the embodiments.

[0047] In some embodiments, the number of elastic elements 122 may be one, and the elastic element 122 abuts against the middle of the clamping element 121. In some embodiments, the number of elastic elements 122 may also be multiple, which can increase the elastic force of the elastic element 122 and make the process of the elastic element 122 pushing the clamping element 121 more stable. The number of elastic elements 122 is not limited in the embodiments of this specification. In some embodiments, multiple elastic elements 122 may be connected by nesting, series, parallel or other methods. In some embodiments, multiple elastic elements 122 may be spaced apart along the extension direction of the receiving groove.

[0048] Figure 4 This is a cross-sectional view of the elastic element shown according to some embodiments of this specification. See also... Figure 4 The following embodiments are for your understanding, but the accompanying drawings are only illustrative of some of the embodiments and do not constitute a limitation on the embodiments.

[0049] like Figure 4As shown, in some embodiments, multiple elastic elements 122 may be nested. In some embodiments, the multiple elastic elements 122 may include a first spring 1221 and a second spring 1222, wherein the diameter of the first spring 1221 is larger than that of the second spring 1222, and the second spring 1222 is disposed inside the first spring 1221.

[0050] The clamping member 121 is a component that applies pressure to the water inlet pipe 200. In some embodiments, the clamping member 121 can directly contact the water inlet pipe 200 under the action of the elastic member 122. Under the action of elastic force, the elastic member 122 will apply an elastic force to the clamping member 121 in the direction of the water inlet pipe 200. Correspondingly, when the clamping member 121 is subjected to pressure in the direction of the water inlet pipe 200, the clamping member 121 applies pressure perpendicular to the outer surface of the water inlet pipe 200, thereby increasing the friction between the water inlet pipe 200 and the clamping member 121, and pressing the water inlet pipe 200 onto the receiving groove 110.

[0051] In some embodiments, the clamping member 121 can be any shape such as plate, block, or column, and this specification does not limit the embodiments.

[0052] In some embodiments, the clamping member 121 has a first cylindrical surface 1211, the axis of the first cylindrical surface 1211 is parallel to the length direction of the receiving groove 110; the inner surface of the first cylindrical surface 1211 faces the opening 112.

[0053] The first cylindrical surface 1211 is a structure on the clamping member 121 used to clamp the water inlet pipe 200.

[0054] In some embodiments, the diameter of the radial section (the section perpendicular to the axis of the first cylindrical surface 1211) of the first cylindrical surface 1211 can be equal to or slightly larger than the outer diameter of the water inlet pipe 200, so that the first cylindrical surface 1211 can just clamp the water inlet pipe 200. By setting the first cylindrical surface 1211, the pressure on the surface of the water inlet pipe 200 can be made more uniform, preventing excessive deformation of some parts of the water inlet pipe 200 from affecting water intake.

[0055] In some embodiments, the arc angle of the radial section of the first cylindrical surface 1211 can be 180°, which maximizes the contact area without affecting the pressing of the water inlet pipe 200 into the first cylindrical surface 1211, allowing the water inlet pipe 200 to withstand greater pressure within an acceptable deformation range, thereby clamping the water inlet pipe 200 more tightly. In some embodiments, the arc angle of the radial section of the first cylindrical surface 1211 can also be any angle. The arc angle of the radial section of the first cylindrical surface 1211 can be set according to actual needs. This specification does not limit the arc angle of the radial section of the first cylindrical surface 1211 in any way.

[0056] The water inlet pipe 200 is clamped by the first cylindrical surface 1211 on the clamping member 121 and the receiving groove 110, which increases the contact area between the clamping member 121 and the water inlet pipe 200. The clamping member 121 and the receiving groove 110 can clamp the water inlet pipe 200 more tightly.

[0057] In some embodiments, the sum of the arc angle of the radial section of the first cylindrical surface 1211 (the section perpendicular to the axis of the first cylindrical surface 121) and the arc angle of the radial section of the second cylindrical surface 1111 is slightly less than 360° (e.g., 355°, 359°, etc.), so that when the clamping member 121 and the receiving groove 110 clamp the water inlet pipe 200 together, they limit the water inlet pipe 200, so that the clamping of the water inlet pipe 200 by the receiving groove 110 and the clamping member 121 is more stable.

[0058] Button 130 is a control component of the cleaning mechanism 100. The operator uses button 130 to clamp or release the water inlet pipe 200. In some embodiments, button 130 is connected to clamping member 121. When it is necessary to place the water inlet pipe 200 into the receiving groove 110, the operator presses button 130. Button 130 pushes clamping member 121 away from the receiving groove 110 and opening 112, allowing the water inlet pipe 200 to be placed into the receiving groove 110. Subsequently, the operator can release button 130, causing elastic member 122 to push clamping member 121 and button 130 in opposite directions under the action of rebound force. Clamping member 121 presses against opening 112 to clamp the water inlet pipe 200. When it is necessary to remove the inlet pipe 200 from the receiving tank 110, the operator can press the button 130 again. The button 130 pushes the clamping member 121 away from the receiving tank 110 and the opening 112. At this time, the inlet pipe 200 is released by the clamping member 121 and removed from the receiving tank 110.

[0059] In some embodiments, the connection between the button 130 and the clamping member 121 can be a fixed connection (e.g., welding, bonding, or fastener connection) or a non-fixed connection (e.g., abutting). This specification does not limit the embodiments.

[0060] In some embodiments, button 130 is connected to clamping member 121 via drive rod 140. One end of drive rod 140 is connected to button 130, and the other end of drive rod 140 is connected to the side of clamping member 121 facing the water inlet pipe 200. Drive rod 140 can transmit control of button 130, extend the control distance, and allow button 130 to be positioned in a more suitable location on cleaning mechanism 100.

[0061] like Figure 2As shown, when the operator does not press button 130 (button 130 is in a pressable state), the elastic element 122 is in a state of small deformation, pressing the clamping element 121 against the opening 112. The first cylindrical surface 1211 of the clamping element 121 and the second cylindrical surface 1111 of the receiving groove 110 clamp the water inlet pipe 200. Figure 3 As shown, when the operator presses button 130, the clamping member 121 is pushed away from the opening 112 via the drive rod 140. The elastic member 122 is compressed, increasing its deformation and increasing the distance between the clamping member 121 and the receiving groove 110, thus releasing the water inlet pipe 200. After the water inlet pipe 200 is released, it can move freely along the axial direction of the receiving groove 110 under the operator's operation. At this time, the operator can pull out or replace the water inlet pipe 200.

[0062] In some embodiments, a flexible protective layer is provided on the clamping member 121 at the location of the opening 112. The flexible protective layer covers the first cylindrical surface 1211. The flexible protective layer can ensure that the clamping member 121 will not damage the water inlet pipe 200 and affect the water flow rate of the water inlet pipe 200. In some embodiments, a flexible protective layer can also be provided on the second cylindrical surface 1111 to ensure that the second cylindrical surface 1111 will not damage the water inlet pipe 200 and affect the water flow rate of the water inlet pipe 200 under the clamping action of the clamping member 121. In some embodiments, the flexible protective layer can be connected to the clamping member 121 and the opening 112 by coating, bonding, electroplating, welding or other arbitrary methods. In some embodiments, the material of the flexible protective layer can be silicone. In some embodiments, the material of the flexible protective layer can also be plastic, rubber or other flexible materials, which are not limited in this specification.

[0063] In some embodiments, the clamping structure 120 further includes a receiving cylinder 123. The inner cavity of the receiving cylinder 123 can be used to receive the elastic element 122 to prevent the elastic element 122 from disengaging from the clamping element 121 during extension and retraction.

[0064] In some embodiments, the receiving cylinder 123 may be any structure capable of accommodating part or all of the elastic member 122, such as a cylindrical or groove-shaped structure with a bottom surface that extends through the center. The bottom of the receiving cylinder 123 (i.e., the end near the clamping member 121) may be fixedly connected to the clamping member 121. When the elastic member 122 applies a force toward the water inlet pipe 200 to the clamping member 121, the elastic member 122 applies force to the bottom of the receiving cylinder 123, thereby pushing the clamping member 121, so that the clamping member 121 and the receiving groove 110 cooperate to clamp the water inlet pipe 200.

[0065] In some embodiments, the receiving cylinder 123 may be a cylindrical structure with a through-center without a bottom surface, one end of which is connected to the clamping member 121.

[0066] In some embodiments, the clamping structure 120 further includes a mounting base 124. The mounting base 124 is a component for securing the elastic member 122. One end of the elastic member 122 away from the clamping member 121 is fixed to the mounting base 124.

[0067] In some embodiments, the mounting base 124 may be part of the housing 300. In some embodiments, the mounting base 124 may be connected to the inner surface of the housing 300 by any means such as bonding, welding or fastening. The embodiments described herein are not limited thereto. Further description of the housing 300 is provided below.

[0068] In some embodiments, a guide post 125 is provided on the side of the mounting base 124 facing the elastic member 122. The guide post 125, the receiving cylinder 123, and the elastic member 122 are coaxially arranged. The receiving cylinder 123 is slidably connected to the guide post 125, which can limit the compression direction of the elastic member 122.

[0069] In some embodiments, the receiving cylinder 123 is sleeved outside the guide post 125. When the operator presses the button 130, the clamping member 121 pushes the receiving cylinder 123 to slide along the radial direction of the guide post 125 toward the mounting base 124; when the operator releases the button 130, the elastic member 122 pushes the receiving cylinder 123 to move along the radial direction of the guide post 125 toward the opening 112.

[0070] When the receiving cylinder 123 slides along the guide post 125, the guide post 125 can extend into the inner cavity of the receiving cylinder 123. In some embodiments, the stroke (i.e., the sliding distance) of the receiving cylinder 123 may be less than the maximum length of the guide post 125 extending into the receiving cylinder 123. Herein, the stroke of the receiving cylinder 123 refers to the distance traveled by the clamping member 121 during the operation of pressing the button 130. When button 130 is not pressed, the elastic element 122 pushes the clamping element 121 toward the water inlet pipe 200 to clamp the water inlet pipe 200. At this time, the deformation of the elastic element 122 is small, and the end of the receiving cylinder 123 facing the guide post 125 is not completely disengaged from the guide post 125. When the operator presses button 130, the clamping element 121 is pushed away from the water inlet pipe 200, the elastic element 122 is compressed, the deformation increases, and the receiving cylinder 123 moves toward the mounting base 124 until the end of the receiving cylinder 123 facing the guide post 125 abuts against the mounting base 124.

[0071] By setting the receiving cylinder 123 and the guide post 125, the elastic element 122 is kept in a relatively closed space between the receiving cylinder 123 and the guide post 125 throughout the process of pressing the button 130, thereby controlling the compression direction of the elastic element 122.

[0072] In some embodiments, the force required to press the button 130 and the force by which the elastic element 122 pushes the clamping member 121 can be adjusted by adjusting the compression amount and elastic coefficient of the elastic element 122 when the button 130 is released. In some embodiments, the compression amount of the elastic element 122 can be adjusted by adjusting the length of the guide post 125.

[0073] In some embodiments, the guide post 125 has a mounting protrusion 1241 on the side facing the elastic member 122. The mounting protrusion 1241 can be integrally formed with the guide post 125. The end of the elastic member 122 away from the opening 112 is sleeved on the mounting protrusion 1241 and is interference-fitted with the mounting protrusion 1241. The end of the elastic member 122 away from the opening 112 is connected to the mounting protrusion 1241, and thus fixed to the mounting base 124. The end of the elastic member 122 away from the opening 112 can also be fixed to the mounting base 124 in other ways. For example, the end of the elastic member 122 away from the opening 112 can be embedded in the mounting base 124. For another example, the end of the elastic member 122 away from the opening 112 can be fixed to the mounting base 124 by any method such as welding, snap-fitting, bonding, or fastener connection. This specification does not limit this.

[0074] In some embodiments, the number of mounting protrusions 1241 may be the same as the number of elastic members 122. In some embodiments, the multiple mounting protrusions 1241 have different diameters and may be stacked, such that each mounting protrusion 1241 can correspond to one of the multiple nested elastic members 122.

[0075] See Figure 1 In some embodiments, the cleaning mechanism 100 further includes at least one cleaning tube 150, and the receiving tank 110 includes a first receiving tank 113 and a second receiving tank 114; one end of one of the cleaning tubes 150 is fixed at a position opposite to the other end of the first receiving tank 113.

[0076] The cleaning pipe 150 is a component that directs water from the inlet pipe 200 to a designated location. This designated location can be a position within the equipment (such as surgical instruments) that the cleaning mechanism needs to clean, based on actual cleaning requirements. For example, the designated location can be located inside the actuator 400.

[0077] In some embodiments, when the cleaning mechanism 100 is used for surgical instruments, the cleaning end of the cleaning tube 150 (i.e., the end opposite to the end connected to the inlet tube 200) can be located anywhere inside the surgical instrument. By positioning the cleaning end at different locations inside the surgical instrument, different areas inside the surgical instrument can be rinsed. For example, the cleaning end can be located at the actuation end 400, the insertion tube 500, or other internal structures of the surgical instrument; further details regarding the actuation end 400 and the insertion tube 500 are provided below.

[0078] The first receiving tank 113 refers to the receiving tank that simultaneously accommodates the water inlet pipe 200 and the cleaning pipe 150.

[0079] In some embodiments, one end of the first receiving tank 113 can be fixed with a water inlet pipe 200, and the other end can be fixed with a cleaning pipe 150. Water in the water inlet pipe 200 enters the cleaning pipe 150 through the first receiving tank 113, and is guided to the cleaning end of the cleaning pipe 150 through the cleaning pipe 150, thereby cleaning the target location.

[0080] The position where one end of the cleaning pipe 150 is fixed opposite to the other end of the first receiving tank 113 means that one end of the cleaning pipe 150 is fixed at a position where the inlet pipe 200 can pass through the other end of the first receiving tank 113 and connect to that end of the cleaning pipe 150. For example, one end of the cleaning pipe 150 can be directly connected to the other end of the first receiving tank 113; or, for another example, the position where one end of the cleaning pipe 150 is fixed can be at a certain distance from the first receiving tank 113, but one end of the cleaning pipe 150 is arranged directly opposite the other end of the first receiving tank 113. When the inlet pipe 200 enters the first receiving tank 113 from one section, it can extend out from the other end of the first receiving tank 113, and at the same time, the inlet pipe 200 connects to the cleaning pipe 150 at the other end of the first receiving tank 113. Water flows from the inlet pipe 200 into the cleaning pipe 150. By connecting the water inlet pipe 200 directly to the cleaning pipe 150, water leakage from the first receiving tank 113 can be prevented, thus reducing the water pressure in the pipe and affecting the cleaning effect.

[0081] In some embodiments, the number of cleaning tubes 150 may include one or more. In some embodiments, the number of cleaning tubes 150 may be the same as the number of receiving tanks 110. For example, when there is one first receiving tank 113 and one second receiving tank 114, one end of a cleaning tube 150 may be provided at a position opposite to the other end of the first receiving tank 113, and one end of a cleaning tube 150 may be provided at a position opposite to the other end of the second receiving tank 114. In some embodiments, the number of cleaning tubes 150 may be less than the number of receiving tanks 110. In this embodiment, the number of cleaning tubes 150 may be the same as the number of first receiving tanks 113. For example, when there is one first receiving tank 113 and one second receiving tank 114, one end of a cleaning tube 150 may be provided at a position opposite to the other end of the first receiving tank 113, and no cleaning tube 150 may be provided on the second receiving tank 114.

[0082] In some embodiments, the second receiving tank 114 refers to a component that only accommodates the water inlet pipe 200. The second receiving tank 114 is not connected to the cleaning pipe 150. After the water from the water inlet pipe 200 enters the second receiving tank 114, it is sprayed directly out of the second receiving tank 114 to clean the space where the second receiving tank 114 is located (e.g., the inside of the housing 300).

[0083] In some embodiments, the second receiving groove 114 can also be used to connect the cleaning pipe 150. The specific configuration can be determined according to actual needs, and this specification does not limit it.

[0084] You can refer to this. Figure 5 The following embodiments are for your understanding, but the accompanying drawings are only illustrative of some of the embodiments and do not constitute a limitation on the embodiments.

[0085] In some embodiments, the cleaning tube 150 includes a tube body 151, a connecting ring 152, and at least one connecting hole 160. The connecting ring 152 is located at one end of the tube body 151 and surrounds the outside of the tube body 151, and the outer diameter of the connecting ring 152 is larger than the outer diameter of the tube body 151.

[0086] The connecting ring 152 is an annular structure used to fix the cleaning tube 150. The connecting ring 152 is disposed at one end of the tube body 151 of the cleaning tube 150 (this end may be referred to as the connecting end). In some embodiments, the connecting ring 152 can be connected to the connecting end of the tube body 151 by means of bonding, welding, fasteners, or integral molding. In some embodiments, integral molding can be achieved by stamping and flanging the connecting end of the tube body 151 along a certain curve based on the expansion deformation of the material of the tube body 151 (i.e., by flanging). The connection method between the connecting ring 152 and the tube body 151 is only an exemplary description, and the embodiments in this specification do not limit the scope of the invention.

[0087] The connecting hole 160 is a component used to engage the connecting ring 152. The connecting hole 160 is located at the other end of the receiving groove 110 (i.e., the end away from the water inlet pipe 200).

[0088] In some embodiments, the diameter of the connecting hole 160 is smaller than the outer diameter of the connecting ring 152. With the cooperation of the connecting ring 152 and the connecting hole 160, one end of the tube body 151 of the cleaning tube 150 (this end can be referred to as the connecting end) can be fixed in the receiving groove 110 and / or the connecting hole 160, so that the connecting end of the tube body 151 of the cleaning tube 150 is engaged with the receiving groove 110 and / or the connecting hole 160.

[0089] In some embodiments, the connecting ring 152 is located within the receiving groove 110, and the portion of the tube body 151 near the connecting ring 152 is located within the connecting hole 160. In this embodiment, the connecting hole 160 is directly connected to the receiving groove 110. The inner diameter of the receiving groove 110 is greater than or equal to the outer diameter of the connecting ring 152, and the diameter of the connecting hole 160 is smaller than the inner diameter of the receiving groove 110. This allows the connecting ring 152 to be engaged in the receiving groove 110 at the position where it contacts the connecting hole 160, thereby ensuring that the connecting end of the tube body 151 of the cleaning tube 150 is engaged with the receiving groove 110 and does not fall off.

[0090] In some embodiments, the connecting ring 152 may also be located outside the receiving groove 110. In this embodiment, there is a certain gap between the connecting hole 160 and the receiving groove 110, and the size of this gap can match the size of the connecting ring 152. The connecting ring 152 is located in the gap between the receiving groove 110 and the connecting hole 160, so that the connecting end of the tube body portion 151 of the cleaning tube 150 is engaged in the gap between the connecting hole 160 and the receiving groove 110.

[0091] In some embodiments, the connecting hole 160 is configured to correspond one-to-one with the cleaning tube 150. In some embodiments, the connecting hole 160 is configured to correspond one-to-one with the connecting ring 152. By engaging the connecting ring 152 with the connecting hole 160, the cleaning tube 150 can be fixed at the opposite position at the other end of the receiving groove 110.

[0092] In some embodiments, the cleaning mechanism 100 further includes a slot 350 and / or a guide hole 360, which are used to position and / or guide the cleaning tube 150. By providing the slot 350 and / or the guide hole 360, the cleaning tube 150 can be prevented from bending, allowing water to smoothly reach the designated location for cleaning.

[0093] See Figure 1 and Figure 6The slot 350 refers to a structure used for positioning and / or guiding the cleaning tube 150. The slot 350 can be disposed on the housing 300. The slot 350 can take various forms. For example, the slot 350 can be a U-shaped structure, a V-shaped structure, or any non-closed structure capable of holding the cleaning tube 150. The cleaning tube 150 can be held within the slot 350 to fix the cleaning tube 150 and / or change the bending direction of the cleaning tube 150. In some embodiments, the width of the slot 350 is smaller than the outer diameter of the cleaning tube 150, and the cleaning tube 150 can be pressed into the slot 350 during installation.

[0094] The guide hole 360 ​​is a structure used for positioning and / or guiding the cleaning tube 150. The guide hole 360 ​​may be provided on the housing 300. The guide hole 360 ​​may be in various forms, such as a through hole structure. In some embodiments, one or more guide holes 360 may be provided on the housing 300. In some embodiments, the diameter of the guide hole 360 ​​may be greater than or equal to the outer diameter of the cleaning tube 150.

[0095] In some embodiments, at least one cleaning tube 150 is engaged within a slot 350 and extends through a guide hole 360 ​​to a location outside the housing of the surgical instrument. For example, the cleaning tube 150 may extend through the guide hole 360 ​​into an insertion tube 500 and extend along the interior of the insertion tube 500 to the actuating end 400. Further description of the actuating end 400 and the insertion tube 500 is provided below.

[0096] In some embodiments, the cleaning mechanism 100 further includes an oblique hole 370. The oblique hole 370 is used to position and / or guide the cleaning tube 150. The oblique hole 370 may be provided on the housing 300. In some embodiments, the oblique hole 370 may be used to guide the cleaning tube 150 into the insertion tube 500.

[0097] In some embodiments, at least one cleaning tube 150 is inserted into the slot 350, passes through the guide hole 360 ​​and the oblique hole 370 into the insertion tube 500, and extends along the interior of the insertion tube 500 to the execution end 400.

[0098] By setting the slot 350, guide hole 360 ​​and oblique hole 370, the cleaning pipe 150 is guided and positioned, and the bending path of the cleaning pipe 150 is fixed to prevent the curvature of the cleaning pipe 150 from being too large, which would cause creases in the path. This allows the cleaning mechanism 100 to smoothly transmit water pressure and water flow to the execution end 400, so as to achieve the purpose of cleaning the execution end 400.

[0099] The beneficial effects that the cleaning structure in the embodiments of this specification may bring include, but are not limited to: (1) by setting a button to control the clamping structure and the receiving groove to clamp and fix or release the water inlet pipe, the insertion and removal operation of the water inlet pipe is more convenient, the water inlet pipe can be clamped more tightly, and the high-quality transmission of water flow and water pressure is achieved; (2) by setting a first cylindrical surface and a second cylindrical surface, the contact area of ​​the clamping member, the receiving groove and the water inlet pipe is increased, the pressure applied by the clamping member to the water inlet pipe towards the receiving groove is dispersed, the water inlet pipe can withstand greater pressure, and the clamping member and the receiving groove can clamp the water inlet pipe more tightly; (3) by setting a flexible protective layer, the contact area between the clamping member and the water inlet pipe is increased. (3) Friction makes the clamping parts and the receiving tank more stable when holding the water inlet pipe; (4) By setting the receiving cylinder and the guide column, the elastic element is in a relatively closed space between the receiving cylinder and the guide column throughout the process of pressing the button, thereby controlling the direction of the force applied by the elastic element to the clamping part; (5) By setting the drive rod to transmit the control of the button, the control distance is extended, so that the button can be set in a more suitable position on the cleaning mechanism; (6) Water is guided to the other end of the cleaning pipe through the cleaning pipe, thereby cleaning the designated position; (7) The connecting ring fixes one end of the cleaning pipe in the receiving tank, so that the water inlet pipe can be connected to the cleaning pipe and water can be passed through after entering the receiving tank, and the end of the cleaning pipe is more stable.

[0100] It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects may be any one or a combination of the above, or any other possible beneficial effects.

[0101] In another aspect, one embodiment of this specification provides a surgical instrument. Figure 7 This is an exemplary cross-sectional view of the surgical instruments shown according to some embodiments of this specification. See also... Figure 7 The following embodiments are for your understanding, but the accompanying drawings are only illustrative of some of the embodiments and do not constitute a limitation on the embodiments.

[0102] In some embodiments, the surgical instrument includes a housing 300 and a cleaning mechanism 100 as described in any of the above embodiments. By using the cleaning mechanism 100 as described in any of the above embodiments, the surgical instrument can be conveniently and thoroughly cleaned.

[0103] like Figure 1-3 and Figure 6 As shown, in some embodiments, the surgical instrument may include a cleaning mechanism 100 and a housing 300. The cleaning mechanism 100 includes a receiving groove 110, a pressing mechanism, and a button 130. The receiving groove 110 and the pressing mechanism 120 are disposed within the housing 300.

[0104] In some embodiments, the receiving tank 110 is capable of receiving the water inlet pipe 200, and the receiving tank 110 includes a sidewall 111 and an opening 112 opposite to the sidewall 111. Further description of the receiving tank 110 is provided above.

[0105] In some embodiments, the clamping structure 120 includes a clamping member 121 and an elastic member 122. The elastic member 122 is compressed and disposed on the side of the clamping member 121 opposite to the opening 112. One end of the elastic member 122 abuts against the clamping member 121, and the other end of the elastic member 122 is fixed to the inner wall of the housing 300. Under the elastic force of the elastic member 122, the clamping member 121 cooperates with the side wall 111 of the receiving groove 110 to clamp the water inlet pipe 200. For further description of the clamping structure 120, see the above.

[0106] In some embodiments, button 130 is movably disposed on housing 300 and connected to clamping member 121. When button 130 is pressed, clamping member 121 moves away from opening 112, causing elastic member 122 to be further compressed. Further description of button 130 is provided above.

[0107] The housing 300 is the main structure of the surgical instrument, which can be used to install various components of the surgical instrument, including the cleaning mechanism 100. When the water inlet pipe 200 is inserted into the cleaning mechanism 100 and water is supplied to it, the water flow can rinse the components inside the housing 300 to achieve the purpose of cleaning the inside of the surgical instrument.

[0108] In some embodiments, the housing 300 is provided with one or more drain holes 310. In some embodiments, the drain holes 310 communicate with the interior of the housing 300. After water is injected into the interior of the housing 300 through the water inlet pipe 200 to rinse the components inside the housing 300, the water can flow out from the drain holes 310 on the housing 300.

[0109] In some embodiments, the housing 300 is provided with a receiving hole 320 for receiving a drive rod 140. In some embodiments, one end of the receiving hole 320 extends to the opening 112, and the other end of the receiving hole 320 extends to the button 130.

[0110] In some embodiments, the surface of the housing 300 is provided with a groove 330 for receiving the button 130. The receiving hole 320 extends to the bottom of the groove 330 at one end facing the button 130.

[0111] See Figure 3 In some embodiments, a limiting hole 340 is provided at the end of the receiving hole 320 facing the button 130.

[0112] The limiting hole 340 is used to limit the drive rod 140. The inner diameter of the limiting hole 340 is smaller than the outer diameter of the drive rod 140. A connecting rod 141 is provided at one end of the drive rod 140 facing the limiting hole 340. The outer diameter of the connecting rod 141 is smaller than the inner diameter of the limiting hole 340. One end of the connecting rod 141 is connected to the drive rod 140, and the other end of the connecting rod 141 passes through the limiting hole 340 and is connected to the button 130. When the button 130 is not pressed, the elastic member 122 presses the clamping member 121 at the opening 112, clamping the water inlet pipe 200. One end of the drive rod 140 is pressed into the receiving hole 320 by the clamping member 121, and the other end of the drive rod 140 abuts against the end of the limiting hole 340 facing the receiving hole 320. The connecting rod 141 pushes the button 130 out of the groove 330. When the operator presses button 130, button 130 abuts against the bottom of groove 330. Button 130 pushes connecting rod 141, causing one end of connecting rod 141 to be pressed into receiving hole 320. The end of driving rod 140 away from connecting rod 141 is pressed out of receiving hole 320, pushing clamping member 121 away from receiving groove 110 and releasing water inlet pipe 200.

[0113] By setting the limiting hole 340 and the connecting rod 141, the range of movement of the drive rod 140 can be limited, preventing the drive rod 140 from coming out of the housing 300.

[0114] In some embodiments, the receiving groove 110 includes a first receiving groove 113 and a second receiving groove 114. Further description of the first receiving groove 113 and the second receiving groove 114 is provided above.

[0115] In some embodiments, the surgical instrument further includes an actuating end 400 and an insertion tube 500, with the actuating end 400 and the housing 300 located at opposite ends of the insertion tube 500.

[0116] The actuator 400 is the part of the surgical instrument that performs surgical operations (such as clamping, cutting, cauterizing), and the design of the insertion tube 500 allows the actuator 400 to enter the patient's body to perform surgical operations.

[0117] In some embodiments, the cleaning mechanism 100 further includes at least one cleaning tube 150. One of the cleaning tubes 150 is inserted into the insertion tube 500, and one end of the cleaning tube 150 is fixed at a position opposite to the other end of the first receiving groove 113, while the other end of the cleaning tube 150 is fixed to the execution end 400.

[0118] Water can be directed to the execution end 400 by placing one end of the cleaning tube 150 through the insertion tube 500 onto the execution end 400 to clean the execution end 400 before or after surgery.

[0119] The beneficial effects that the surgical instruments in the embodiments of this specification may bring include, but are not limited to: (1) By applying the cleaning mechanism of any of the above technical solutions to the surgical instruments, the operator can control the clamping and fixing or releasing of the water inlet pipe by controlling the control button, thereby making the insertion and removal process of the water inlet pipe more convenient, the water inlet pipe can be clamped more tightly, and the high-quality transmission of water flow and water pressure can be achieved; (2) By setting a drain hole, water is injected into the housing through the water inlet pipe, and after rinsing the components inside the housing, the water flow can flow out from the drain hole on the housing; (3) By setting a limiting hole and a connecting rod, the movement range of the drive rod can be limited, preventing the drive rod from coming out of the housing; (4) By setting a slot, guide hole and oblique hole to guide and position the cleaning pipe, fix the bending path of the cleaning pipe, prevent the curvature of the cleaning pipe from being too large and causing creases in the path, so that the cleaning mechanism can smoothly transmit water pressure and water flow to the execution end, and achieve the purpose of cleaning the execution end.

[0120] It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects may be any one or a combination of the above, or any other possible beneficial effects.
