Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an intervention piece and an integrated arthroscopic system, which are particularly suitable for use in joint treatment scenarios. Background Art

[0002] In modern medical surgeries, bipolar plasma surgical electrodes and arthroscopes, as important medical devices, are widely used in various minimally invasive surgeries. Taking the posterior cruciate ligament (PCL) of the knee joint as an example, the PCL is one of the important stabilizing structures of the knee joint, located inside the knee joint, connecting the femur and the tibia. Its main function is to prevent the tibia from shifting backward and maintain the stability of the knee joint. Currently, the conventional surgical methods at home and abroad are arthroscopic-assisted posterior medial and posterior lateral four-incision posterior cruciate ligament reconstruction techniques. By respectively placing an arthroscope and a plasma electrode knife in multiple incisions, under the monitoring of the arthroscope, the tibial ligament stump of the posterior cruciate ligament is cleaned using radiofrequency plasma or a shaver to facilitate subsequent surgical work. The plasma electrode knife has excellent cutting and coagulation capabilities, while the arthroscope is used to observe and operate on the internal structures of the joint.

[0003] However, in the prior art, the plasma electrode knife and the arthroscope are used separately, often requiring multiple incisions to be formed on the patient's body surface and multiple doctors to cooperate in the operation, resulting in a complex surgical process, a long instrument preparation time, and an extended patient recovery time.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

The above definitions are only for the convenience of expression and should not be construed as a limitation to the present invention.

[0021] It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present invention. And in the following embodiments, each embodiment has its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0022] The present invention first provides a medical device, which is preferably applicable to the treatment scenarios of joint cutting and removal, for example, the directional removal of bones or soft tissues near joints can be achieved through this medical device.

[0023] Refer to Figures 1 - 6, which is a schematic structural diagram of an integrated arthroscopic system provided by a specific embodiment of the present invention, includes an intervention member 100 that can be at least partially inserted into a patient's body, an operating member (not shown in the figure) communicatively connected to the intervention member 100, and a display member (not shown in the figure) communicatively connected to the intervention member 100. The intervention member 100, the operating member, and the display member can be separately and independently arranged, and they are communicatively connected wirelessly. Of course, they can also be used in a wired manner. The present invention does not limit this.

[0024] The intervention member 100 includes a cannula portion 110, a base portion 120, an electrode portion 130, and a detection portion 140. The base portion 120 is fixedly arranged on a window at the distal end of the cannula portion 110, and the electrode portion 130 and the detection portion 140 are fixedly arranged on the same side of the base portion 120. The cannula portion 110 is a hollow tubular member and has a distal end and a proximal end. Preferably, the window of the cannula portion 110 is arranged on the side wall near the distal end, so that the base portion 120 is fixedly arranged on the side of the distal end of the cannula, and the electrode portion 130 and the detection portion 140 are fixedly arranged on the side of the base portion 120 away from the cannula. Of course, the window can also be arranged at the distal end of the cannula portion 110. The present invention does not limit this. In Figure 1 In this specific embodiment, the base portion 120 is fitted and arranged in a window on the distal side wall of the cannula portion 110 of the cannula to be fixedly connected to the cannula portion 110. The electrode portion 130 and the detection portion 140 are both arranged on the side of the base portion 120 away from the cannula, that is, on the upper side of the base portion 120. The advantage of such an arrangement is that it can well increase the size area of the base portion 120, thereby reducing the difficulty of arranging various components on the base portion 120 and reducing the manufacturing cost.

[0025] The electrode portion 130 is communicatively connected to the operating member, and the display member is communicatively connected to the detection portion 140. The electrode portion 130 is arranged to be able to interact with other components to generate high-frequency current and then generate plasma. Through the plasma, precise cutting and vaporization of tissues of the patient can be completed, and at the same time, it also has a hemostatic function. There are many solutions in the prior art for the electrode portion 130 to interact with other components to generate plasma. For example, monopolar or bipolar radiofrequency plasma can be used for cutting, and details are not described here. The operating member can control the switch of the electrode member and adjust the power of the electrode member, thereby realizing the control of the generated plasma.

[0026] In Figure 1In this specific embodiment, the electrode part 130 is preferably cut by bipolar radiofrequency plasma. The sleeve part 110 is made of a conductive material. The electrode part 130 and the sleeve part 110 have opposite polarities and are insulated and connected through the base part 120. And a set liquid capable of exciting plasma that can conduct the electrode part 130 and the sleeve part 110 is provided / filled in the patient's body, such as normal saline. Thus, plasma can be selectively generated between the electrode part 130 and the sleeve part 110, and specific uses in the diseased area can be realized, such as cutting or hemostasis.

[0027] Specifically, the electrode part 130 includes a wire 133, an electrode piece 131, and an electrode wire 132 electrically connected to the electrode piece 131. The electrode wire 132 is electrically connected to the wire 133. The electrode wire 132 can provide current, preferably radiofrequency current, to the electrode piece 131 through the wire 133. The electrode wire 132 and the electrode piece 131 are preferably made of materials that can withstand radiofrequency current, such as materials containing tungsten. For the current sources of the electrode piece 131 and the sleeve part 110, it is preferred that power supply components provided at the proximal end of the sleeve part 110 are electrically connected through the wire 133 respectively so that the electrode polarities of the electrode piece 131 and the sleeve part 110 are different. The power supply components are also communicatively connected to the operating piece so that the power supply components can be controlled by the operating piece to adjust the magnitude and switch of the current. At this time, the wire 133 is sleeved inside the sleeve part 110 and is insulated from the sleeve part 110. Specifically, this can be achieved by providing multiple insulating layers on the outer layer of the wire 110, which will not be elaborated here. In a preferred manner, the power supply component at the proximal end and the operating piece are integrated, that is, the power supply component is part of the operating piece. At this time, the operating piece and the electrode are electrically connected through a cable.

[0028] Thus, by setting the sleeve part 110 and the base part 120 as two ends with opposite polarities and insulated from each other through the base part 120, and using the set liquid injected or already existing in the patient's body, the generation of plasma can be well realized, and then functions such as cutting, hemostasis, or other functions can be completed.

[0029] Please continue to refer to Figures 1 - 3 , the interventional device 100 further includes an outer tube heat shrinkable tube 180 made of an insulating material. The outer tube heat shrinkable tube 180 is partially sleeved outside the sleeve part 110 to be hermetically connected to the sleeve part 110, and there is a certain gap with the window of the sleeve part 110. When the outer tube heat shrinkable tube 180 is heat shrinkably connected to the sleeve part 110, the part of the sleeve part 110 covered by the outer tube heat shrinkable tube does not contact the set liquid in the patient's body. Thus, the area where the sleeve part 110 contacts the set liquid in the patient's body is defined, and the operating area where plasma can be generated is defined. At the same time, the outer tube heat shrinkable tube is provided to improve the waterproof and anti-corrosion capabilities of the covered part of the sleeve part 110. There are many solutions for heat shrinkable tubes in the prior art, which will not be elaborated here.

[0030] Similarly, please continue to refer to Figures 1 - 3 , the intervening member 100 further includes a tip cap 190 made of an insulating material. The tip cap 190 is sleeved on the distal end of the sleeve portion 110 and covers the position of the window, and there is a certain gap from the distal end of the outer tube heat shrinkable tube 180, so as to better define the area where the sleeve portion 110 contacts the set liquid in the patient's body. At the same time, it can also improve the waterproof and anti-corrosion capabilities of the covered part of the sleeve portion 110. There are many solutions for the tip cap 190 in the prior art, which will not be elaborated here.

[0031] Please continue to refer to Figure 1 , the detection portion 140 and the electrode portion 130 are disposed on the base portion 120 without interfering with each other. An installation ring 123 for installing the detection portion 140 is provided on the base portion 120. The detection portion 140 is inclined toward the electrode portion 130, so that the detection portion 140 can detect the area where the electrode portion 130 is located and send the detected information to the display member, so as to display the information of the area where the electrode portion 130 is located in the patient's body through the display member. In Figure 1 In this specific embodiment, the detection portion 140 is disposed at the distal end of the electrode portion 130, and the installation ring 123 is inclined toward the electrode portion 130, thereby driving the detection portion 140 to be inclined toward the electrode portion 130. Naturally, it can be understood that in addition to the detection portion 140 being disposed at the distal end of the electrode portion 130, the electrode portion 130 can also be disposed at the distal end of the detection portion 140, and it can be freely set according to actual scenario requirements.

[0032] It can be understood that for the inclination angle A of the detection portion 140, that is, the included angle formed by the detection portion 140 in the far and near directions, the present invention does not limit this, as long as the area where the electrode portion 130 is located can be detected. It depends on the distance between the detection portion 140 and the electrode portion 130. The closer the detection portion 140 is to the electrode portion 130, the smaller the inclination angle A at this time. The farther the distance between the detection portion 140 and the electrode portion 130, the larger the inclination angle A. Preferably, the inclination angle A of the detection portion 140 is 5°-15°, preferably 10°. The advantage of selecting 10° is that it can better see the field of view about 3 mm away from the base portion 120 on the side of the electrode portion 130, and can better complete the surgical operation.

[0033] It should be noted that for the detection portion 140, it is preferably an arthroscope with a camera 141. The advantage of selecting it is that the detected image is relatively clear and direct, and the stability is good. The camera is preferably Howeell OV6946, which has a high degree of miniaturization, can better adapt to the intervening device, and is better applied to joint treatment.

[0034] Therefore, by integrating the electrode part 130 and the detector part 140 on the base 120, the electrical connection between the electrode part 130 and the detector part 140 can be well achieved. When it is needed, only one incision needs to be made on the patient's body surface, and it does not require the cooperation of multiple operators, which can well reduce the surgical preparation time and operation difficulty, and improve the surgical efficiency and patient recovery time.

[0035] However, during the research and development process, the inventors found that in existing medical scenarios, in addition to using the electrode unit 130 and the detection unit 140, doctors also need to inject a set medium such as saline into the patient area where the electrode unit 130 is located in the patient's body. By injecting saline, the patient area is locally expanded, thereby achieving more accurate operation and observation. At the same time, in order to better achieve the generation of plasma through the interaction of the electrode unit 130 with other components and then achieve subsequent cutting, hemostasis and other functions, it is also necessary to inject a set liquid into the patient area to help better generate plasma. However, for the injection of a set liquid represented by saline into the patient area, an incision is often required, resulting in low surgical efficiency and poor patient experience. At the same time, considering that some tissues may block the field of view of the detection unit 140 during use, resulting in a poor field of view of the detection unit 140, the inventors tried to make further improvements to the solution.

[0036] See also Figures 1 - 6 The interventional device 100 further includes an injection portion 150 and a suction portion 160. The injection portion 150 can inject physiological saline into the patient area. Of course, other setting liquids that can expand the patient area and can conduct the electrode portion 130 and the cannula portion 110 and excite plasma can also be injected. The suction portion 160 can suck out the substances to be cleaned in the patient area, such as free tissue.

[0037] The suction part 160 can suck out the material to be cleaned in the patient area. The suction part 160 includes a suction port 161 and a suction tube 162, and the suction tube 162 is partially arranged in the sleeve part 110 and communicated with the suction port 161. The suction port 161 is preferably integrated with the electrode sheet 131 of the electrode part 130, that is, the electrode sheet 131 is provided with a plurality of through holes for facilitating the passage of the material to be cleaned, and the suction tube 162 is arranged below the electrode sheet 131 and communicated with the suction port 161, so that the material to be cleaned enters the suction tube 162 from the suction port 161, and is then transported to a specific position or component at the proximal end of the sleeve part 110 by the suction tube 162. The advantage of such a setting is that after the electrode wire 132 of the electrode part 130 completes the operation on the patient area, for example, after the cutting is completed, the suction part 160 can complete the cleaning of the material to be cleaned in the shortest path, thereby reducing the amount of the material to be cleaned in the patient's body as much as possible.

[0038] Naturally, it can be understood that since the electrode piece 131 is fixedly arranged on the base 120, the base 120 itself has a certain thickness and is made of an insulating material, such as a ceramic material. At this time, a first cavity 121 is arranged in the area of the base 120 corresponding to the suction port 161, and the suction pipe 162 is hermetically communicated with the first cavity 121. Furthermore, the communication with the suction port 161 is realized through the first cavity 121, that is, one end of the first cavity 121 is communicated with the suction port 161, and the other end is communicated with the suction pipe 162.

[0039] The injection part 150 can inject a set liquid into the patient area, such as normal saline. Of course, other set liquids that can excite plasma and can expand the patient area can also be injected. The injection part 150 includes an injection pipe 151, a guide part 152 and a spray port 153. The injection pipe 151 is sleeved in the sleeve part 110 and is insulated from the sleeve part 110, and is not affected by the suction pipe 162 of the suction part 160 and the wire 133 of the electrode part 130, and they are insulated from each other in the sleeve 110. The proximal end of the injection pipe 151 is communicated with a memory (not shown in the figure) storing normal saline, and the distal end is communicated with the guide part 152. The guide part 152 can guide the normal saline in the injection pipe 151 to flow to the spray port 153 according to a set flow path, and enable the normal saline to be injected into the patient area in the patient's body through the spray port 153, so that the electrode part 130 and the sleeve part 110 are wrapped with normal saline in the patient area. The guide part 152 is fixedly arranged on the base 120, and the spray port 153 is arranged on the surface of the base 120 and on one side of the electrode part 130 and the detection part 140.

[0040] Thus, by arranging the injection part 150 and the suction part 160, the further integration of the arthroscopic system can be well realized, so that the injection part 150 and the suction part 160 are also integrated together, further improving the surgical efficiency and reducing the trauma to the patient.

[0041] However, as mentioned above, the inventor considered that since the integrated detection part 140 is blocked by the substances to be cleaned in the patient area and cannot observe the patient area, so an attempt was made to make further improvements.

[0042] Please refer to Figure 1 、 Figure 4 , the spray port 153 is arranged on the circumferential side of the detection part 140 and is inclined towards the spray port 153. Preferably, a plurality of spray ports 153 are arranged and circumferentially surround the detection part 140. Both ends of the guide part 152 are communicated with the spray port 153 and the injection pipe 151 respectively to guide the normal saline in the injection pipe 151 to the spray port 153 and then flow out to the patient area.

[0043] Thus, by circumferentially arranging the injection port 153 beside the detection unit 140, after injecting the set liquid into the injection port 153 through the injection tube 151, the set liquid is sprayed onto the patient area through the injection port 153, and the cleaning substances that have blocked or may block the visual field of the detection unit 140 can be washed away, thereby ensuring a better observation visual field. At the same time, by arranging the injection port 153 towards the detection unit 140, the visual field in front of the detection unit 140 can be better guaranteed.

[0044] Please continue to refer to Figures 1 - 6 , the guiding member 152 is fixedly arranged on the base 120, preferably integrally arranged with the base 120. A second cavity 122 is arranged on the guiding member 152 for connecting the injection part 150 and the injection port 153, and the connection position of the second cavity 122 and the injection part 150 does not interfere with the installation position where the detection unit 140 is placed. The intervention member 100 further includes a fixing plate 170. A flow channel for guiding the flow of physiological saline is arranged on the side of the base 120 facing away from the injection port 153. The fixing plate 170 is fixedly sealed with the base 120 to form the second cavity 122 for the flow channel, and one end of the second cavity 122 is communicated with the injection tube 151, and the other end is communicated with the injection port 153.

[0045] The fixing plate 170 is provided with a first hole 171 and a second hole 172 which are arranged without interference. The first hole 171 is arranged at the corresponding position for installing the injection tube 151, so that the fixing plate 170 can be hermetically connected with the injection tube 151, and thus the injection tube 151 is connected with the second cavity 122. The second hole 172 is arranged within the corresponding position of the mounting ring 123, and the size of the second hole 172 is smaller than that of the second hole 172, so that the fixing plate 170 is hermetically fixed with the mounting ring 123, and the second hole 172 is left to facilitate the installation of the detection unit 140.

[0046] On the one hand, considering that the second cavity 122 is mainly used to accommodate physiological saline, that is, liquid needs to flow through it, and the detection unit 140 needs to be placed in the mounting ring 123, but the detection unit 140 itself needs electricity as the power to drive. Considering that the device itself belongs to an interventional medical device and has high safety requirements, it is necessary to strictly ensure the sealed isolation between the detection unit 140 and the second cavity 122 to achieve dry-wet separation. And through this method, on the one hand, it can ensure that the second cavity 122 and the detection unit 140 in the mounting ring 123 do not interfere with each other, achieve dry-wet separation, ensure safety, and the method of reserving the second hole 172 also increases the installation flexibility for the subsequent arrangement of the detection unit 140.

[0047] For example, in Figure 1 、 Figure 3In this specific embodiment, the detection unit 140 includes a camera 141, an LED lamp 142, and a detection wire 143. The LED lamp 142 is arranged on the periphery of the camera 141 to achieve supplementary lighting. The detection wire 143 is electrically connected to the LED lamp 142 and the camera 141 to supply power to them. The power supply component of the detection wire 143 is arranged at the proximal end of the sleeve part 110. At this time, the detection wire 143 needs to pass through the base part 120 and the sleeve part 110 to reach the proximal end. By reserving the second hole 172, this purpose can be well achieved and interference with the second cavity 122 can be avoided.

[0048] On the other hand, the advantage of forming the second cavity 122 by sealing and fixing the fixing plate 170 and the base part 120 is that in the actual production and manufacturing process, the base part 120 is mainly made of ceramic materials. If the second cavity 122 is directly formed integrally, that is, the base part 120 and the fixing plate 170 are integrally arranged, it has high requirements for the existing ceramic molds, and the manufacturing difficulty is large, resulting in too high overall manufacturing cost and defective rate, and it is difficult to carry out large-scale application and mass production promotion.

[0049] However, through the solution of the present invention, by sealing and fixing the fixing plate 170 and the base part 120 to form the second cavity 122, the problem of large manufacturing difficulty brought by integrally forming the second cavity 122 can be well reduced, the manufacturing efficiency is greatly improved, and further the manufacturing cost can be better reduced, which is convenient for large-scale popularization and application.

[0050] Furthermore, a flanging 124 is also arranged on the base part 120. The flanging 124 is arranged on the side of the base part 120 facing the fixing plate 170 and matches with a part of the side wall of the fixing plate 170 to realize the fixation of the fixing plate 170 and the base part 120. The advantage of such a setting is that the sealing and fixation of the base part 120 and the fixing plate 170 can be better realized. At the same time, since the flanging 124 is sealed with a part of the side wall of the fixing plate 170, a guiding function can also be realized, which is more convenient for the installation of the fixing plate 170 and the base part 120 and improves the installation efficiency.

[0051] Naturally, it can be understood that there are many solutions for the fixation of the fixing plate 170 and the base part 120 in the prior art. For example, adhesive bonding and sealing can be achieved through adhesives, bonding parts, etc., and mechanical sealing fixation can also be achieved through setting mechanical mechanisms such as mortise and tenon, or other solutions that can achieve adhesive bonding and sealing in the prior art, which will not be elaborated here.
