Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] This is the first embodiment of the present invention, which provides a steerable suction, flushing, hemostatic and electrocoagulation hook.

[0035] Specifically, refer to Figure 1 to Figure 5 , a main body assembly 100, including a handle 101, a disassembly button 102 provided at the end of the handle 101, and an adjustment component;

[0036] The electrocoagulation hook assembly 200 disposed at the end of the handle 101 includes a connector 201 and an electrocoagulation hook 202 disposed at the end of the connector 201. A connection channel 2034 is disposed at the end of the connector 201. The connection channel 2034 is sleeved on the outside of the electrocoagulation hook 202 and communicated with the inside of the handle 101 to switch functions according to the adjustment component. At the same time, the connector 201 is used to drive the electrocoagulation hook 202 to rotate and adjust the angle.

[0037] The disassembly button 102 is pressed to replace the electrocoagulation hook assembly 200. At the same time, the adjustment component located at the end of the handle 101 is used to control the switching status of the suction channel 103 and the flushing channel 104 arranged on the inner wall of the handle 101. The function is switched according to needs. At the same time, the connecting head 201 can be moved at the end of the handle 101. During suction or flushing, the electrocoagulation hook 202 is covered by the connecting channel 2034 for operation.

[0038] Among them, the front ends of the suction channel 103 and the flushing channel 104 are connected together and connected to the connecting head 201. The rear part of the electrocoagulation hook 202 is fixed to the connecting head 201 and the electrocoagulation hook 202 extends out from the connecting channel 2034. The connecting head 201 as a whole can be rotated at the end of the handle 101, which facilitates the overall 360-degree rotation of the electrocoagulation hook 202, changing the existing technology that the electrocoagulation hook can only be operated in a single direction. At the same time, the connecting head 201 can also adjust the inclination angle of the electrocoagulation hook 202 independently.

[0039] The adjustment component is installed above the handle 101, and is used to adjust the switch status of the suction channel 103 and the flushing channel 104. The two are adjusted separately and there is no conflict between the two. When the field of vision at the surgical site is not clear or there is a lot of exudate, flushing fluid can be added for cleaning; it can also suck out the smoke generated during the operation or excess liquid at the surgical site.

[0040] Example 2

[0041] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0042] Specifically, refer to Figure 1 to Figure 5 The connecting head 201 is clamped on the inner wall of the handle 101 and a connecting block 2012 is provided on the inner wall of the connecting head 201. A guide rod 2013 is fixed on the outer wall of the connecting block 2012. The electrocoagulation hook 202 is hinged on the end of the guide rod 2013. An arc plate 2021 is provided on the end of the electrocoagulation hook 202 and the outer wall of the arc plate 2021 is in conflict with the roller 2014 provided on the inner wall of the guide rod 2013. A first elastic member 2015 is provided on the end of the roller 2014. The first elastic member 2015 pushes the roller 2014 to lift the arc plate 2021.

[0043] Among them, the bottom position of the guide rod 2013 is fixed on the connecting block 2012 inside the connecting head 201, and the movement of the guide rod 2013 is affected by the connecting head 201. The top position of the guide rod 2013 is hinged to the outer wall of the electrocoagulation hook 202. At the same time, the first elastic member 2015 in the top position of the guide rod 2013 pushes the roller 2014 to move upward and close to the middle position of the arc plate 2021 below the electrocoagulation hook 202. When not affected by the outside world, the roller 2014 is always located in the middle of the arc plate 2021, so that the electrocoagulation hook 202 is vertically located at the end position of the guide rod 2013.

[0044] Preferably, a connecting ring 2022 is hinged at the end of the arc plate 2021 and a pull rope 2023 is provided at the end of the connecting ring 2022. The other end of the pull rope 2023 is connected to an inner ring 203 provided on the inner wall of the connecting head 201. The pull rope 2023 passes through a fixed block 2016 located on the outer wall of the connecting head 201. The pull rope 2023 is used to pull the end of the arc plate 2021 to deflect and thereby adjust the angle of the electrocoagulation hook 202 at the end of the guide rod 2013.

[0045] Among them, connecting rings 2022 are hinged at both ends of the arc plate 2021 and the bottom of the connecting ring 2022 is fixed to the pull rope 2023, and the other end of the pull rope 2023 is fixed to the inner ring 203 on the outer wall of the connecting head 201 through the fixed block 2016. When the pull rope 2023 is affected and moves, the pull rope 2023 on one side moves and pulls the arc plate 2021 through the connecting ring 2022 at the top of the pull rope 2023, so that the electrocoagulation hook 202 is tilted toward the side of the moving pull rope 2023, changing the original vertical state of the electrocoagulation hook 202. At the same time, the arc plate 2021 below is affected by the pull rope 2023 and squeezes the roller 2014, so that it moves downward inside the guide rod 2013 and squeezes the first elastic member 2015.

[0046] Preferably, a slider 2031 is provided on the inner wall of the inner ring 203 and the slider 2031 slides with the slide groove 2011 opened on the outer wall of the connecting head 201, and the rotating block 2032 sleeved on the outer wall of the inner ring 203 moves together with the inner ring 203, and a rotating head 2033 is provided on the outer wall of the rotating block 2032, and a connecting channel 2034 is provided at the end of the rotating head 2033, and the connecting channel 2034 is sleeved on the outer wall of the guide rod 2013 for auxiliary support of the guide rod 2013, and a shift block 2035 is provided on the inner wall of the rotating head 2033 and the shift block 2035 is located on the outer wall of the pull rope 2023, and the shift block 2035 rotates with the rotating head 2033 on the outer wall of the connecting head 201 to drive the pull rope 2023 to move so as to adjust the angle of the electrocoagulation hook 202.

[0047] Among them, the inner ring 203 is sleeved on the outside of the connecting head 201, and the slider 2031 on the inner wall of the inner ring 203 slides with the slide groove 2011 on the surface of the connecting head 201. The inner ring 203 only moves linearly on the outside of the connecting head 201. At the same time, a rotating block 2032 is fixed on the outside of the inner ring 203. The rotating block 2032 can drive the connecting head 201 to rotate on the inner wall of the handle 101, and the guide rod 2013 on the surface rotates with the rotating block 2032 together with the electrocoagulation hook 202. The direction of the electrocoagulation hook 202 can be adjusted at will, which is convenient for the operator to use.

[0048] At the same time, a rotating head 2033 is also arranged outside the rotating block 2032, and the rotating head 2033 and the rotating block 2032 are movably connected. The connecting channel 2034 connected to the axial position of the rotating head 2033 is sleeved on the outside of the guide rod 2013. When the guide rod 2013 rotates, it rotates inside the connecting channel 2034. At the same time, the electrocoagulation hook 202 also rotates inside the connecting channel 2034 to adjust the direction. The shifting block 2035 arranged on the inner wall of the rotating head 2033 is located in the middle of the two pull ropes 2023. Figure 3 As shown, by rotating the rotating head 2033, the shifting block 2035 can be driven to pull the pull rope 2023, so as to adjust the inclination angle of the electrocoagulation hook 202, and when it is necessary to cooperate with the connecting channel 2034 for flushing and suction, the inner ring 203 is driven by the rotating block 2032 to slide outward on the outer wall of the connecting head 201, so that the connecting channel 2034 can accommodate the electrocoagulation hook 202 inside, avoiding the electrocoagulation hook 202 being exposed to the outside and causing obstruction when the connecting channel 2034 is used to flush or suction excess liquid in the surgical site.

[0049] In summary, when in use, the electrocoagulation hook 202 is energized through the energy connector 105 disposed on the outside of the handle 101, the connector 201 is engaged inside the handle 101 and can be affected by the rotating block 2032, and the connector 201 is driven to rotate inside the handle 101 through the inner ring 203. When the connector 201 rotates, the guide rod 2013 fixed on the outside thereof and the electrocoagulation hook 202 at the top of the guide rod 2013 rotate together, and the direction of the electrocoagulation hook 202 can be adjusted at will through the rotating block 2032, which is convenient for the operator to use, and the rotating head 2033 on the outside of the rotating block 2032 can also be The pull rope 2023 is controlled by the internal dial block 2035, and the inclination angle of the electrocoagulation hook 202 located on the top of the guide rod 2013 is controlled by the movement of the pull rope 2023, which is more conducive to fine electrocoagulation operations in tiny tissue areas, thereby reducing errors caused by inconvenient operations, and when it is necessary to aspirate liquid from the surgical site or flush the surgical site in the future, the inner ring 203 is pushed outward on the outside of the connector 201, so that the connecting channel 2034 can be extended outward for a section, and the electrocoagulation hook 202 can be accommodated inside, which can prevent the electrocoagulation hook 202 from leaking outside during subsequent operations and affecting the flushing and aspiration work.

A transverse groove 1014 is also opened at the end of the second fixed groove 1013. An inclined block 1015 is provided at the end of the transverse groove 1014 and the inclined block 1015 is located at the end of the flushing channel 104.

[0064] Among them, the second fixed groove 1013 has the same shape as the first fixed groove 1011, except that the top position of the second fixed groove 1013 is additionally connected to a horizontal groove 1014, and the second pressing rod 1081 slides inside the second fixed groove 1013. When it is located in the upper inclined channel, the flushing channel 104 is opened, and when it slides to the locking channel below, the flushing channel 104 is squeezed to close it. The inclined block 1015 below has the same function as the supporting block 1012, except that the inclined block 1015 presents an upward slope.

[0065] Preferably, a fifth elastic member 1083 is sleeved on the outer wall of the flush button 108, and the fifth elastic member 1083 is located on the inner wall of the guide block 106 for pushing the second pressing rod 1081 upward. A second slider 1082 is also provided on the outer wall of the flush button 108 and the second slider 1082 slides on the inner wall of the guide groove 1061 opened on the inner wall of the guide block 106.

[0066] Among them, an elastic member is respectively sleeved on the outside of the flushing button 108 and the suction button 107. The functions of the flushing button 108 and the suction button 107 are roughly the same, each controlling the closure of a channel. The difference is that a second slider 1082 is provided on the surface of the flushing button 108. When the second pressing rod 1081 is located in the inclined channel above the second fixed groove 1013, the second slider 1082 is flush with the guide groove 1061 inside the guide block 106. When the flow in the flushing channel 104 needs to be adjusted, the flushing button 108 is pushed horizontally, and the second slider 1082 slides into the guide groove 1061. The second pressing rod 1081 below slides from the inclined channel into the horizontal groove 1014 next to it. Due to the inclined block 1015 below, the second pressing rod 1081 gradually squeezes the flushing channel 104 to reduce the internal flow.

[0067] In summary, when in use, the electrocoagulation hook 202 is energized through the energy connector 105 to perform the electrocoagulation tourniquet work. When suction or flushing is required, the rotating block 2032 outside the connecting head 201 is pushed to move the rotating head 2033 and the connecting channel 2034 outward for a distance, so that the front end position of the connecting channel 2034 can store and hide the electrocoagulation hook 202 to avoid the electrocoagulation hook 202 affecting the work during subsequent suction or flushing.

[0068] At this time, the flushing and suction state is entered. By pressing the flushing button 108 or the suction button 107, the opening and closing states of the flushing channel 104 and the suction channel 103 inside the handle 101 can be controlled. The selection is made according to specific usage requirements. When the flushing state requires adjustment of the flow of the fluid inside the flushing channel 104, the flushing button 108 is pushed horizontally so that the internal second pressing rod 1081 slides from the inclined channel at the top of the second fixed groove 1013 into the adjacent horizontal groove 1014. The further it is pushed in the direction of the horizontal groove 1014, the more the second pressing rod 1081 squeezes the flushing channel 104, and the smaller the flow inside the flushing channel 104. When the second pressing rod 1081 is pushed back to the inclined channel at the top of the second fixed groove 1013, pressing the flushing button 108 downward will cause the second pressing rod 1081 to enter downward into the locking channel below to close the flushing channel 104.

[0069] When it is necessary to replace another electrocoagulation hook assembly 200, press the disassembly button 102 to rotate the push ring 1022 inside the handle 101, press the raised end of the locking rod 1025, and remove the locking tooth 1027 from the locking groove on the surface of the connector 201, so as to facilitate the removal of the connector 201 and replace the entire electrocoagulation hook assembly 200. During installation, just push the connector 201 inward, squeeze the locking tooth 1027 upward through the front end of the connector 201, and finally engage it in the locking groove of the connector 201 to complete the replacement of the entire electrocoagulation hook assembly 200.
