Detailed implementation manners
[0019] Next, the technical solutions in the embodiments of the present invention will be described in detail in combination with the attached Figures 1 - 13 , of the present invention. Embodiment
[0020] AsFigure 1 , 2 As shown in FIGS. 13, a visualization bone and soft tissue tumor ablation device with ablation function includes an operating handle 1, an ablation rod 11, an ablation spoon 2, an endoscope lens 3, and a tissue clamping forceps 4. One end of the ablation rod 11 is connected to the operating handle 1, and an ablation spoon 2 is provided at the other end of the ablation rod 11. The tissue clamping forceps 4 are connected to the ablation rod 11 through a clamping forceps installation tube 5, and the endoscope lens 3 is provided on the clamping forceps installation tube 5, between the tissue clamping forceps 4 and the ablation spoon 2.
[0021] The main function of the operating handle 1 is to install other accessories in the ablation rod 11 and the microwave ablation needle. At the same time, the operating handle 1 is also convenient for the operator to hold.
[0022] The main function of the ablation spoon 2 is to ablate bone tumor tissues. At the same time, the setting of the ablation spoon 2 also facilitates the scooping and cleaning of the ablated tissues through the spoon body 21 of the ablation spoon 2, which is convenient to use and avoids frequent replacement of medical devices during use.
[0023] The main function of the endoscope lens 3 is to visualize the ablation and cleaning processes. The integrated design of the endoscope lens 3 and the ablation needle makes the overall operation of the device more convenient and fast.
[0024] The main function of the tissue clamping forceps 4 is to assist in clamping the ablated tissues, which is suitable for cleaning some tissues that are difficult to scoop with the ablation spoon 2. For the convenience of operation, the tissue clamping forceps 4 can be controllably contracted in the clamping forceps installation tube 5. At the same time, a telescopic control part 6 and a clamping control part 7 are correspondingly provided in the operating handle 1. The telescopic control of the tissue clamping forceps 4 in the clamping forceps installation tube 5 can be controlled through the telescopic control part 6, and the opening and closing of the tissue clamping forceps 4 can be controlled through the clamping control part 7, which is convenient for clamping tissues.
[0025] As Figure 1 and 13 shown, the operating handle 1 is a hollow shell made of plastic. The operating handle 1 is composed of two upper and lower outer shells, and the two outer shells are connected together by screws. The connected outer shells form a complete operating handle 1. There is a cavity inside the operating handle 1 for installing the telescopic control part 6, the clamping control part 7, and the control part 9.
[0026] To facilitate the installation of the telescopic control part 6, two rectangular openings are provided on the surface of one of the outer shells of the operating handle 1. One of the openings is named the first moving sliding opening 12, and the other opening is named the second moving sliding opening 13. The telescopic control part 6 is installed on the operating handle 1 through the first moving sliding opening 12, and the clamping control part 7 is installed on the operating handle 1 through the second moving sliding opening 13.
[0027] To facilitate the installation of the ablation rod 11, a circular opening is provided at the other end of the operating handle 1. The ablation rod 11 is inserted into the operating handle 1 through this opening and connected to the operating handle 1. After connection, it is fixed with glue to ensure the stability of the fixation.
[0028] To facilitate the connection between the ablation spoon 2 and the ablation rod 11, at the port of the other end of the ablation rod 11, a circular groove is recessed perpendicularly to the end face. This groove is named the installation groove. The clamping forceps installation tube 5 connected to the ablation spoon 2 is connected to the ablation rod 11 through this installation groove to complete the fixation of the ablation spoon 2.
[0029] As Figure 1 、 3 As shown in Figures 4 and 5, the ablation spoon 2 includes a spoon body 21. The spoon body 21 is made of stainless steel material that meets medical standards, and the spoon body 21 is overall spoon-shaped.
[0030] To facilitate microwave ablation, a rectangular hole is recessed in the middle of the spoon body 21 near the spoon head. This hole is named the generator installation hole. The generator installation hole is provided in the middle of the spoon body 21, and a distance for opening the cooling water channel 23 is reserved between the edge of the generator installation hole and the edge of the spoon body 21. To facilitate the installation of the microwave generator 22, an installation block made of polytetrafluoroethylene is embedded in the generator installation hole. This installation block is named the generator installation block 24. The microwave generator 22 is fixed in this generator installation block 24. In addition, to facilitate the connection between the ablation spoon 2 and the ablation rod 11, a clamping forceps installation tube 5 is integrally fixed at the spoon handle of the spoon body 21. The ablation spoon 2 is connected to the ablation rod 11 through the clamping forceps installation tube 5.
[0031] The microwave generator 22 is a device for generating and emitting microwaves, which is an existing structure and can be directly used. To facilitate providing energy to the microwave generator 22, the microwave generator 22 is connected to the control unit 9 provided inside the operating handle 1 through a microwave cable 25.
[0032] To facilitate the routing of the microwave cable 25, a microwave cable installation hole 26 for the routing of the microwave cable 25 is provided inside the spoon body 21. The microwave cable 25 passes through the microwave cable installation hole 26 and then is connected to the control unit 9 through the hollow ablation rod 11.
[0033] To facilitate the heat dissipation of the microwave generator 22 during use and ensure the normal use of the device, a cooling water channel 23 for the circulation of cooling water is provided inside the spoon body 21 near the edge of the spoon body 21. The cooling water circulates through the cooling water channel 23 to dissipate heat and cool down the spoon body 21.
[0034] Regarding the opening of the cooling water channel 23 and the microwave cable installation hole 26 on the spoon body 21, since both the cooling water channel 23 and the microwave cable installation hole 26 are arc-shaped and change along with the contour of the spoon body 21, in this embodiment, it is preferred that the spoon body 21 is made by using the existing mature 3D printing technology.
[0035] As Figure 1 、 3 and shown in 10, in order to facilitate the installation of the tissue clamping forceps 4, a circular clamping forceps installation tube 5 is welded at the handle of the spoon body 21, and the tissue clamping forceps 4 can be telescopically installed in the clamping forceps installation tube 5.
[0036] The clamping forceps installation tube 5 is a circular metal tube, and in this embodiment, it is preferably made of 304 stainless steel that meets medical standards.
[0037] In order to facilitate the installation of the tissue clamping forceps 4, a chamber with a rectangular cross-section is recessed perpendicularly to the end face at one end of the clamping forceps installation tube 5. This chamber is named the clamping forceps installation chamber 51, and the tissue clamping forceps 4 is placed in this clamping forceps installation chamber 51.
[0038] In order to facilitate the connection between the clamping forceps installation tube 5 and the ablation rod 11, a circular connecting platform 52 protrudes outward perpendicularly to the end face at the other end of the clamping forceps installation tube 5. The inner diameter of the connecting platform 52 is the same as the inner diameter of the clamping forceps installation tube 5, and the outer diameter of the connecting platform 52 is the same as the inner diameter of the installation groove on the ablation rod 11. The clamping forceps installation tube 5 is connected to the ablation rod 11 through the connecting platform 52 and the installation groove, and a sealing treatment is performed at the connection.
[0039] On the end face of the clamping forceps installation tube 5, perpendicular to the end face and parallel to the clamping forceps installation chamber 51, two circular cooling water pipe installation holes 53 and a microwave cable installation port 54 are opened. Among them, the two cooling water pipe installation holes 53 are respectively communicated with the cooling water channel 23 opened on the ablation spoon 2, and the microwave cable installation port 54 is communicated with the microwave cable installation hole 26 opened on the ablation spoon 2. The microwave cable 25 passes through the ablation spoon 2 and the clamping forceps installation tube 5 and is connected to the control part 9 in the operation handle 1.
[0040] In order to facilitate the real-time viewing of the ablation process and the cleaning process after ablation, an installation hole for installing the endoscope lens 3 is opened on the end face of the clamping forceps installation tube 5 away from the connecting platform 52. At the same time, the wire on the endoscope lens 3 passes through the installation hole and is connected to the control part 9.
[0041] As Figure 2 、 6As shown in Figures 7, 8, and 9, the tissue clamping forceps 4 includes a fixed jaw 41 and a movable jaw 42. The fixed jaw 41 is movably hinged to the movable jaw 42 to form forceps for clamping tissue. After the clamping mouth of the tissue clamping forceps 4 formed by the fixed jaw 41 and the movable jaw 42 is closed, the cross-sectional dimension of the entire tissue clamping forceps 4 is the same as that of the forceps installation cavity 51, which facilitates the tissue clamping forceps 4 to contract into the forceps installation cavity 51.
[0042] The movable jaw 42 is a metal block with a rectangular cross-section. Perpendicular to the end face at the rear end of the movable jaw 42, a rectangular connecting block protrudes outward. A hinge hole is provided on the connecting block, and the movable jaw 42 is hinged to the fixed jaw 41 through the hinge hole.
[0043] Definition: In this embodiment, the direction from the operating handle 1 to the ablation spoon 2 is defined as the front, and the opposite direction is the rear.
[0044] The fixed jaw 41 is a metal block with a rectangular cross-section. To facilitate the installation of the movable jaw 42, a rectangular hole is provided in the fixed jaw 41, and this rectangular hole is named the movable jaw installation opening 43. The connecting block on the movable jaw 42 is placed at the movable jaw installation opening 43 and is hinged to the fixed jaw 41 through pinning, and the movable jaw 42 can rotate freely along the hinge.
[0045] To improve the clamping effect of the tissue clamping forceps 4, anti-slip lines are recessed at the closing part of the fixed jaw 41 and the movable jaw 42, and the clamping effect of the tissue clamping forceps 4 can be further enhanced through the anti-slip lines.
[0046] To facilitate the opening and closing of the tissue clamping forceps 4 and facilitate the clamping of the ablated bone tumor tissue, a rectangular block protrudes outward on the side of the connecting block at the end of the movable jaw 42, and this rectangular block is named the spring mounting plate 45. A spring is fixed on the spring mounting plate 45, and this spring is named the first spring 46. One end of the first spring 46 is fixed on the spring mounting plate 45, and the other end abuts against the inner side wall of the movable jaw installation opening 43. Under the action of the first spring 46, the movable jaw 42 rotates relative to the fixed jaw 41 along the hinge to complete the opening of the clamping mouth of the tissue clamping forceps 4.
[0047] To control the closing of the clamping mouth of the tissue clamping forceps 4 and achieve clamping, a rectangular rope pulling fixing block 47 protrudes and is fixed on the lower side of the side of the connecting block at the end of the movable jaw 42. A rope pulling fixing hole is provided in the rope pulling fixing block 47, and a clamping rope 48 is fixed on the rope pulling fixing block 47 through the rope pulling fixing hole. The clamping rope 48 is connected to the clamping control part 7 inside the operating handle 1. After the clamping mouth of the tissue clamping forceps 4 is opened, the rope pulling fixing block 47 rotates along the hinge with the movable jaw 42. Pulling the clamping rope 48 can drive the movable jaw 42 to rotate along the hinge to complete the reset of the movable jaw 42, and further achieve the closing of the clamping mouth of the tissue clamping forceps 4.
[0048] At the rear end of the tissue clamping forceps 4, in order to close the moving chuck mounting port 43 and facilitate the connection between the telescopic control part 6 and the tissue clamping forceps 4, a rectangular block is fixed in the moving chuck mounting port 43 with screws. This rectangular block is named the sealing block 44. The moving push rod 612 in the telescopic control part 6 is connected to the sealing block 44. The moving chuck mounting port 43 is closed at the rear end of the tissue clamping forceps 4 through the sealing block 44. In order to ensure the smooth opening and closing of the tissue clamping forceps 4, the clamping pull rope 48 passes through the sealing block 44 and is connected to the clamping control part 7.
[0049] The setting of the sealing block 44 is mainly to facilitate the connection with the telescopic control part 6, and at the same time prevent larger tissues after ablation from entering the moving chuck mounting port 43, affecting the normal opening and closing of the tissue clamping forceps 4.
[0050] As Figure 1 、 11 As shown in 12, the telescopic control part 6 includes an adjustment slider 61, a limit mechanism 65 and a moving push rod 612. The moving push rod 612 connects the adjustment slider 61 and the tissue clamping forceps 4. The telescopic movement of the tissue clamping forceps 4 can be controlled through the adjustment slider 61. The limit mechanism 65 is connected to the adjustment slider 61. The position of the adjustment slider 61 on the operating handle 1 can be restricted and adjusted through the limit mechanism 65, so as to realize the restriction and maintenance of the position of the tissue clamping forceps 4 after adjustment, and prevent the tissue clamping forceps 4 from accidentally retracting during the process of using the tissue clamping forceps 4 to clamp tissues, affecting normal use.
[0051] In order to facilitate the installation of the adjustment slider 61, a rectangular first moving slide opening 12 is opened on the outer shell of the operating handle 1. The adjustment slider 61 is clamped at the first moving slide opening 12 and can slide linearly along the first moving slide opening 12.
[0052] The adjustment slider 61 is a rectangular plastic block. The width of the adjustment slider 61 is slightly larger than the width of the first moving slide opening 12. Anti-slip lines are provided on the surface of the adjustment slider 61 to facilitate the user to push. In order to facilitate the adjustment slider 61 to be fixed at the first moving slide opening 12, rectangular grooves are recessed on the two side surfaces of the adjustment slider 61. This groove is named the sliding groove 62. The sliding groove 62 can cooperate with the side wall of the first moving slide opening 12 to clamp the adjustment slider 61 at the first moving slide opening 12, so that the adjustment slider 61 can slide stably along the first moving slide opening 12.
[0053] To facilitate controlling the telescoping of the tissue grasping forceps 4 by adjusting the adjusting slider 61, a rectangular plate protrudes perpendicularly from the surface of the adjusting slider 61 placed inside the operating handle 1. This plate is named the connecting plate 610. A circular metal rod is fixed to the connecting plate 610 with screws. This metal rod is named the moving push rod 612. One end of the moving push rod 612 is connected to the connecting plate 610, and the other end is connected to the sealing block 44 on the tissue grasping forceps 4. Pushing the adjusting slider 61 can drive the moving push rod 612 to move, thereby controlling the movement of the tissue grasping forceps 4 within the forceps installation tube 5 to achieve telescoping control.
[0054] To limit the position of the adjusting slider 61 and thereby limit the position of the tissue grasping forceps 4, a limiting mechanism 65 is provided on the adjusting slider 61.
[0055] The limiting mechanism 65 includes a limiting block 66, a limiting groove 67, a limiting block mounting plate 68, a guiding rod 69, and a guiding sleeve 611. Among them, the limiting groove 67 is a groove with a triangular cross-section. The limiting groove 67 is opened on the inner side wall of the operating handle 1, on both sides of the first moving sliding opening 12, and multiple limiting grooves 67 are arranged at intervals.
[0056] The limiting block 66 for cooperating with the limiting groove 67 is fixed to the limiting block mounting plate 68. The guiding sleeve 611 is fixed to the adjusting slider 61. The guiding rod 69 is fixed to the limiting block mounting plate 68. The guiding rod 69 can cooperate with the guiding sleeve 611, enabling the limiting block mounting plate 68 connected with the limiting block 66 to move up and down along the guiding sleeve 611, thereby releasing the cooperation between the limiting block 66 and the limiting groove 67.
[0057] The limiting block 66 is a rectangular plastic block. One end of the limiting block 66 is triangular and can cooperate with the limiting groove 67. The limiting block mounting plate 68 is a rectangular plastic plate, and its main function is to fix the limiting block 66. The limiting block 66 is provided on both sides of the limiting block mounting plate 68, so that the two limiting blocks 66 mounted on the limiting block mounting plate 68 can respectively cooperate with the limiting grooves 67 on both sides of the first moving sliding opening 12.
[0058] The guiding sleeve 611 is a circular sleeve. There are two guiding sleeves 611, which are respectively fixed to the surface of the adjusting slider 61 located inside the operating handle 1. The guiding rod 69 is a circular rod. The guiding rod 69 can cooperate with the guiding sleeve 611. There are two guiding rods 69, which are respectively fixed to the limiting block mounting plate 68, to guide the limiting block mounting plate 68 to move up and down along the guiding sleeve 611 and the guiding rod 69.
[0059] In the normal state, in order to keep the limiting block 66 always cooperating with the limiting groove 67, a spring is fixed between the adjusting slider 61 and the limiting block mounting plate 68. This spring is named the tension spring 64. Under the action of the tension spring 64, the limiting block 66 and the limiting groove 67 are always in a cooperating state.
[0060] To release the cooperation between the limit block 66 and the limit groove 67 and facilitate the movement and adjustment of the position of the adjustment slider 61, a circular through-hole is provided in the adjustment slider 61, and an unlocking button 63 is placed in the circular through-hole. The unlocking button 63 is a circular plastic rod. The unlocking button 63 passes through the adjustment slider 61 and is fixed on the limit block mounting plate 68, and extends out of the adjustment slider 61 for a certain length. Pressing the unlocking button 63 can drive the limit block mounting plate 68 to move along the guide sleeve 611, thereby releasing the cooperation between the limit block 66 and the limit groove 67, facilitating the adjustment of the position of the adjustment slider 61, and further controlling the telescopic movement of the tissue clamping forceps 4.
[0061] As Figure 1 、 8 and shown in Fig. 13, the clamping control part 7 includes a control slider 71 and a guide pulley 72. The guide pulley 72 is fixed in the operating handle 1 by a pin. The control slider 71 is clamped at the second moving slide 13 and is connected to the clamping pull rope 48 connected to the pull rope fixing block 47 through the guide pulley 72. Moving the control slider 71 can pull the clamping pull rope 48 to move, thereby realizing the control of the closing of the clamping mouth in the tissue clamping forceps 4.
[0062] The control slider 71 is a rectangular plastic block. The width of the control slider 71 is slightly larger than the width of the second moving slide 13. Anti-slip patterns are provided on the surface of the control slider 71 to facilitate the user's pushing. To facilitate the fixing of the control slider 71 at the second moving slide 13, concave grooves that can cooperate with the side walls of the second moving slide 13 are provided on the two side surfaces of the control slider 71. The control slider 71 is clamped at the second moving slide 13. Pushing the control slider 71, the control slider 71 can slide stably along the second moving slide 13.
[0063] A rectangular pull rope fixing plate is fixed on the control slider 71. The clamping pull rope 48 passing around the guide pulley 72 is connected to the pull rope fixing plate. Pushing the control slider 71 can drive the clamping pull rope 48 to move. And to ensure the stability of the clamping pull rope 48 on the guide pulley 72, the clamping pull rope 48 and the guide pulley 72 are treated to prevent derailment, preventing the clamping pull rope 48 from falling off the guide pulley 72. The treatment of the pull rope on the pulley to prevent derailment is a mature existing technology and is well-known to those skilled in the art, so it will not be elaborated here.
[0064] When the tissue clamping forceps 4 extends out of the clamping forceps installation tube 5, to avoid the tissue clamping forceps 4 being unable to extend out of the clamping forceps installation tube 5 due to the length of the clamping pull rope 48, the length of the clamping pull rope 48 should be slightly longer, that is, when the tissue clamping forceps 4 completely extends out of the clamping forceps installation tube 5, the clamping pull rope 48 will be tightened, and at this time, pushing the control slider 71 can control the closing of the tissue clamping forceps 4.
[0065] As Figure 4 、5 As shown in FIGS. 12 and 13, the cooling part 8 includes a water inlet pipe 81 and a water outlet pipe 82.
[0066] One end of the water inlet pipe 81 and the water outlet pipe 82 is connected to two cooling water pipe mounting holes 53 opened on the clamping forceps mounting pipe 5, and the other end passes through the ablation rod 11, passes through the operation handle 1 and is connected to the water connection port on the external microwave ablation instrument. Through the circulating water pump in the microwave ablation instrument, circulating water can be introduced into the ablation spoon 2 to achieve the cooling of the ablation spoon 2.
[0067] Regarding the connection between the water inlet pipe 81 and the water outlet pipe 82 and the cooling water pipe mounting hole 53, glue connection can be selected to ensure the sealing performance.
[0068] As Figure 1 and 13 shown, a control part 9 is arranged in the operation handle 1, and the control part 9 includes a control board 91 and an intelligent wire 92.
[0069] The microwave cable 25 connected to the microwave generator 22 in the ablation spoon 2 passes through the ablation rod 11 and is connected to the control board 91, and after the ablation data is processed and transformed by the control board 91, it is connected to the external microwave ablation instrument through the intelligent wire 92, and the ablation power of the microwave generator 22 is adjusted through the microwave ablation instrument.
[0070] The control line on the endoscope lens 3 passes through the ablation rod 11 and is connected to the control board 91, and after being processed by the control board 91, it is connected to the external display for convenient viewing.
[0071] Regarding the processing and transformation of ablation data by the control board 91, and the processing of the digital signal of the camera by the control board 91, it is the prior art and will not be elaborated here. In addition, the microwave ablation instrument is an existing device that can be connected to the microwave ablation needle to adjust the ablation power and supply cooling circulating water for the ablation process.
[0072] In order to prevent the smoke generated during the ablation process from affecting the vision during use, a suction pipe 14 can also be installed in the ablation rod 11. One end of the suction pipe 14 passes through the ablation rod 11 and the operation handle 1 and is connected to the existing external negative pressure suction device, and the smoke is sucked out through the negative pressure suction.
[0073] In order to facilitate the suction of smoke by the suction pipe 14, a circular through hole is opened at one end of the ablation spoon 2 away from the spoon head, and this through hole is named the smoke suction port 27. At the same time, a hole corresponding to the smoke suction port 27 is also opened on the clamping forceps mounting pipe 5. The other end of the suction pipe 14 passes through the clamping forceps mounting pipe 5 and is connected to the smoke suction port 27, and the smoke during the ablation process is sucked out through the smoke suction port 27 and the suction pipe 14.
[0074] Usage process of this embodiment: When in use, first turn on the endoscope lens 3. Under the action of the endoscope lens 3, the whole device is inserted into the affected area through the opened cavity. Then turn on the microwave generator 22 on the ablation spoon 2, and tissue ablation can be carried out under visual conditions. When it is necessary to clean the tissue after ablation, the ablation spoon 2 can be used to directly dig out the ablated and fallen tissue to achieve cleaning. When it is difficult to dig out the tissue that needs to be clamped, push the adjustment slider 61 to push out the tissue clamping forceps 4, and then push the control slider 71 to clamp the tissue that is difficult to dig out with the endoscope lens 3, which is convenient to use.
[0075] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
