[0032] This embodiment discloses a cutter head that can work in radio frequency and plasma modes separately and a medical surgical device including the cutter head, which can perform surgeries with the assistance of an endoscope. Specifically, the medical surgical device further includes a handle and a main unit, and the cutter head that can work in radio frequency and plasma modes separately is connected to the main unit through the handle.
[0033] As Figures 1 to 4 shown, the cutter head that can work in radio frequency and plasma modes separately includes an electrode head assembly and an insulating part assembly. Among them, the electrode head assembly includes a first electrode head 1, a second electrode head 2, and a third electrode head 3, and the insulating part assembly includes a first insulating part 4 and a second insulating part 5. The first insulating part 4 is disposed between the first electrode head 1 and the second electrode head 2, and the second insulating part 5 is disposed between the second electrode head 2 and the third electrode head 3.
[0034] At any working moment, only two of the first electrode head 1, the second electrode head 2 and the third electrode head 3 are powered on, and the third electrode head is powered off. When one of the first electrode head 1, the second electrode head 2 and the third electrode head 3 is powered off, the cutter head that can work in the radio frequency and plasma modes in time-sharing is in the radio frequency working mode; when another of the first electrode head 1, the second electrode head 2 and the third electrode head 3 is powered off, the cutter head that can work in the radio frequency and plasma modes in time-sharing is in the plasma working mode.
[0035] Specifically, there are three combinations: the first electrode head 1 and the second electrode head 2 are powered on, and the third electrode head 3 is powered off; the first electrode head 1 and the third electrode head 3 are powered on, and the second electrode head 2 is powered off; the second electrode head 2 and the third electrode head 3 are powered on, and the first electrode head 1 is powered off. Among the above three combinations, the user can select one to execute the RF working mode and another to execute the plasma working mode according to needs, and the remaining one is not implemented.
[0036] The blade head that can work in radio frequency and plasma modes at different times is equipped with three electrode heads, with only two electrode heads being powered on at a time, so that the radio frequency working mode and the plasma working mode are integrated into one device, and it has both plasma bipolar ablation function and radio frequency bipolar coagulation effect, and integrates the two existing devices into one device, thereby reducing costs. The needs during the operation can be met without replacing the blade head, thus simplifying the surgical operation, shortening the operation time, alleviating the pain of compression of the lesion on the patient's nerves, and facilitating the patient's rapid recovery; and reducing the cost of surgery.
[0037] The materials for making the first insulating part 4 and the second insulating part 5 are not limited, and any materials that have insulating functions and meet medical safety standards in the prior art can be used. The specific shapes of the first insulating part 4 and the second insulating part 5 are also not limited, as long as the volume is reduced while achieving insulation between two adjacent electrode heads and the outer surface has no sharp structures that can easily scratch human blood vessels.
[0038] On the basis of the above structure, the first electrode head 1 is designed as a sheet structure. Compared with the cylindrical structure, the sheet-shaped first electrode head 1 contacts the body tissue more evenly during the operation, can form energy for operating on the body tissue, can quickly complete vaporization and cutting ablation, shorten the operation time, and reduce the patient's pain.
[0039] The first electrode head 1 can be an integral structure, which is easy to process, has low manufacturing difficulty and is easy to use; the first electrode head 1 can also include at least two independent first sub-electrode heads, all of which form a sheet structure, and each first sub-electrode head is connected to a power supply. During the operation, one or several first sub-electrode heads can be powered as needed, which can complete the radio frequency working mode and plasma working mode for a specific lesion site, and avoid damage to other parts, thereby achieving a better surgical effect.
[0040] The second electrode head 2 is annular, and the first insulating portion 4 is partially disposed in the second electrode head 2. The first insulating portion 4 can insulate and isolate the second electrode head 2 from the first electrode head 1, and can also support the second electrode head 2, so that the position of the second electrode head 2 on the cutter head that can work in the RF and plasma modes at different times is more stable, thereby improving the working stability of the cutter head that can work in the RF and plasma modes at different times.
[0041] The second electrode head 2 can be an integral ring structure, which is easy to process and install. The distance between the second electrode head 2 and the first electrode head 1, and the distance between the second electrode head 2 and the third electrode head 3 remain unchanged. The energy of executing the radio frequency working mode and the plasma working mode is more stable, and the surgical effect is good.
[0042] The second electrode head 2 may also include at least two independent arc-shaped second sub-electrode heads, and all the second sub-electrode heads form a ring. Each second sub-electrode head is connected to a power source, and one or several second sub-electrode heads can be powered as needed during surgery, which can not only complete the radio frequency working mode and plasma working mode for a specific lesion site, but also avoid damage to other sites, reducing the patient's pain.
[0043] The third electrode head 3 is a metal tubular structure, which can be connected to the host through a handle. The length and diameter of the third electrode head 3 are not limited and can be determined according to the use requirements. The third electrode head 3 can be an integral metal tubular structure, which is connected to the handle through a lead wire, has low processing difficulty and is easy to use.
[0044] The third electrode head 3 may also include at least two sections of third sub-electrode heads connected in sequence, and all the third sub-electrode heads are connected to form a tubular structure. The third electrode head 3 of this structure can be directly connected to the handle, eliminating the lead structure, and is more convenient for disassembly and assembly. The specific connection method between all the third sub-electrode heads is not limited. On the basis of being able to form a metal tubular structure, a certain degree of relative rotation can occur between two adjacent third sub-electrode heads, so that the third electrode head 3 can be bent as needed, which is suitable for various surgical environments.
[0045] When the first electrode head 1 is of an integral structure and the second electrode head 2 is of an integral ring structure, the knife head that can work in radio frequency and plasma modes separately includes three electrode heads and has a radio frequency working mode and a plasma working mode. In this embodiment, the first electrode head 1 includes two first sub-electrode heads, and the second electrode head 2 includes two second sub-electrode heads. The knife head that can work in radio frequency and plasma modes separately includes a total of five electrode heads, namely two first sub-electrode heads, two second sub-electrode heads and a third electrode head 3, which can be combined as needed. On the basis of ensuring the realization of the radio frequency working mode and the plasma working mode, ablation, coagulation and other operations can be performed on the lesion, minimizing the damage to the non-lesion area and achieving faster postoperative healing.
[0046] The distances between the first electrode head 1, the second electrode head 2 and the third electrode head 3 are not specifically limited and need to be determined according to the selected working current and working state. In this embodiment, the distance between the first electrode head 1 and the second electrode head 2 is 0.4 mm to 0.6 mm, and the distance between the first electrode head 1 and the third electrode head 3 is 5 mm to 6 mm.
[0047] The specific way in which the knife head that can work in radio frequency and plasma modes separately is connected to the host through the handle is not limited. It can be that the first electrode head 1, the second electrode head 2 and the third electrode head 3 are directly connected to the host through the handle, or the first electrode head 1, the second electrode head 2 and the third electrode head 3 are connected to the host through the handle by a traction wire.
[0048] In this embodiment, the knife head that can work in radio frequency and plasma modes separately further includes a loop lead wire 6 and a working lead wire 7 that are insulated from each other.
[0049] One of the loop lead wire 6 and the working lead wire 7 passes through the second insulating part 5 and is connected to the second electrode head 2 to supply power to the second electrode head 2; the other of the loop lead wire 6 and the working lead wire 7 passes through the second insulating part 5 and the first insulating part 4 and is connected to the first electrode head 1 to supply power to the first electrode head 1. Among all the loop lead wire 6 and the working lead wire 7, one of the wires can be made to have a traction function, or an independent traction wire can be provided to move the first electrode head 1 and the second electrode head 2 to the target position.
[0050] There is no limit to the specific method by which the loop lead wire 6 and the working lead wire 7 pass through the second insulating part 5 and the first insulating part 4. In this embodiment, through holes, notches or slots are respectively formed in the second insulating part 5 and the first insulating part 4, and the loop lead wire 6 and the working lead wire 7 pass through the through holes, notches or slots. There is no limit to the specific number of through holes, notches or slots formed in the second insulating part 5 and the first insulating part 4, which can be determined according to the number of the loop lead wire 6 and the working lead wire 7, as long as all the loop lead wire 6 and the working lead wire 7 are isolated from each other to achieve insulation, so as to avoid the loop lead wire 6 and the working lead wire 7 being tangled together and affecting the normal use of the cutter head that can work in the radio frequency and plasma modes separately.
[0051] In order to avoid confusing the loop lead wire 6 and the working lead wire 7, in this embodiment, the loop lead wire 6 and the working lead wire 7 have different cross-sectional shapes in the radial direction. During installation, the user does not need to continuously straighten from the first electrode head 1 and the second electrode head 2 to determine which is the loop lead wire 6 and which is the working lead wire 7, and only needs to look at the cross-sectional shapes of the loop lead wire 6 and the working lead wire 7 to make a determination, with high installation efficiency. The shape of the through holes in the second insulating part 5 and the first insulating part 4 can be consistent with the cross-sectional shapes of the loop lead wire 6 and the working lead wire 7 in the radial direction, which can better fix the loop lead wire 6 and the working lead wire 7, and the cutter head works more stably. In order to protect the loop lead wire 6 and the working lead wire 7, sleeves (not shown) can be sleeved outside the loop lead wire 6 and the working lead wire 7.
[0052] Certainly, markers can also be respectively arranged outside the loop lead wire 6 and the working lead wire 7, which can also distinguish the two. The marker can be, but is not limited to, forming coatings of different colors or engraving patterns of different shapes on the outside of the loop lead wire 6 and the working lead wire 7.
[0053] On the basis of the above structure, as Figure 5 shown, the handle includes a connecting sleeve 81, a front sleeve 82, a rear sleeve 83, a switching button 84, a connecting cable 85 and an operating handle 86. The cutter head that can work in the radio frequency and plasma modes separately is inserted into the connecting sleeve 81. Specifically, at least two mutually isolated sleeve cavities (not shown) are arranged in the connecting sleeve 81, and the extending direction of the sleeve cavities is consistent with the extending direction of the connecting sleeve 81. Each loop lead wire 6 and working lead wire 7 is respectively inserted into a different sleeve cavity.
[0054] The front sleeve 82 is relatively fixed to the connecting sleeve 81. It can be that the front sleeve 82 and the connecting sleeve 81 are an integral structure, or the front sleeve 82 and the connecting sleeve 81 are independent of each other but fixedly connected together, as long as the front sleeve 82 and the connecting sleeve 81 can move synchronously.
[0055] The cutter head that can work in radio frequency and plasma modes separately is fixedly connected to the rear sleeve 83 after passing through the connecting sleeve 81. The operating handle 86 can make the front sleeve 82 and the rear sleeve 83 move relative to each other, so that the cutter head that can work in radio frequency and plasma modes separately extends or retracts into the connecting sleeve 81, facilitating accurate access to the lesion location and removing the body tissue to be excised.
[0056] The switching button 84 is used to control the cutter head that can work in radio frequency and plasma modes separately to be in the radio frequency working mode, in the plasma working mode, or switch between the radio frequency working mode and the plasma working mode to meet the specific usage requirements of the operation and make it more convenient to use. The switching button 84 can directly control the energization and de-energization of the first electrode head 1, the second electrode head 2, and the third electrode head 3, or the switching button 84 can control the energization and de-energization of the first electrode head 1, the second electrode head 2, and the third electrode head 3 through the host. The functions of these two control methods are the same and can be determined according to the usage situation.
[0057] Whether the switching button 84 directly or through the host controls the energization and de-energization of the first electrode head 1, the second electrode head 2, and the third electrode head 3, the first electrode head 1, the second electrode head 2, and the third electrode head 3 all need to be connected to the power supply of the host. In this embodiment, one end of the connection cable 85 is connected to the cutter head that can work in radio frequency and plasma modes separately, and the other end of the connection cable 85 is connected to the host. The specific structure of the switching button 84 is not limited, and any device in the prior art that can directly or indirectly control the energization and de-energization of the first electrode head 1, the second electrode head 2, and the third electrode head 3 can be used.
[0058] Note that the above is only the preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here, and various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
