Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a two-in-one cutter head tool. Background Art

[0002] An arthroscope is an endoscope as thick as a chopstick, with a lens with a lighting device at the end. When using an arthroscope, it is inserted into the knee, shoulder, elbow, ankle and other joints through a minimally invasive surgical incision on the skin. It can observe the joint structure, find diseased tissues, and display the structure in the joint cavity on the screen in the form of a magnified high-definition image.

[0003] During clinical surgery, doctors usually need to make a minimally invasive incision on the skin, insert an arthroscope for observation, and then make another minimally invasive incision on the skin. For this minimally invasive incision, if ablation and hemostasis operations are required, a radiofrequency ablation tool needs to be inserted for operation. If cutting is required, the radiofrequency tool needs to be removed from the minimally invasive incision first, and then the planing tool needs to be inserted into the same minimally invasive incision.

[0004] The applicant has found that the prior art has at least the following technical problems: Due to the complex tissue structure inside the joint cavity, the two tools mentioned above need to be switched frequently. For example, for simple arthroscopic surgery, it may be necessary to switch more than 10 times, and for complex arthroscopic surgery, it may be necessary to switch dozens of times. In addition, due to the complex anatomical structure under the arthroscopic endoscope, the surgeon may not be in the original position after pulling out the blade and inserting another blade, and needs to readjust and find the original position under the endoscope, which not only causes damage to the patient's skin incision and surrounding tissues, but also makes the doctor easily fatigued, and also prolongs the operation time, which also causes potential harm to the patient. Summary of the invention

[0005] The purpose of the present invention is to provide a two-in-one blade tool to solve the technical problem that radiofrequency ablation blade tools and shaving blade tools in the prior art need to be frequently taken out and switched at the patient's minimally invasive incision.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] Reference Figures 1 to 3 The present invention mentions a two-in-one tool head, including a radio frequency component 1, a planing component 2, a guide rod 3 and a handle 4. One end of the guide rod 3 is connected to the radio frequency component 1 and the planing component 2, and this end can be defined as a working end. The radio frequency component 1 and the planing component 2 are located on both sides opposite to each other and are arranged back to back. The other end of the guide rod 3 is connected to the handle 4.

[0033] By respectively arranging the radio frequency component 1 and the planing component 2 on both sides of the working end of the guide rod 3, the radio frequency blade head and the planing blade head can be integrated together to form a two-in-one blade head tool with an integrated design. In the actual surgical process, it only needs to be inserted once into the minimally invasive surgical incision, and there is no need to frequently remove and insert different tools. When radio frequency is needed, it is only necessary to align the side with the radio frequency component 1 with the lesion position. When planing is needed, the handle 4 can be rotated 180 degrees, and the side with the planing component 2 can be aligned with the lesion for treatment;

[0034] Compared with existing technologies, the application of two-in-one blade tools can reduce surgical operation steps and effectively reduce damage and harm to the patient's skin incision and surrounding tissues. At the same time, it is convenient and quick to operate, more handy and more efficient. In addition, it can effectively shorten the operation time, reduce the possibility of doctor fatigue and reduce surgical risks.

[0035] As an optional embodiment, the guide rod 3 and the handle 4 are detachably connected. With this arrangement, the guide rod 3 can be disposable, and the handle 4 can be reused after being disinfected and cleaned. The detachable connection allows the disposable guide rod 3 to be easily disassembled and assembled with the handle 4. After use, the guide rod 3 can be removed and the handle 4 can be cleaned and retained. When it needs to be used again, a new guide rod 3 can be connected to the handle 4.

[0036] As an optional embodiment, the planing assembly 2 includes a planing saw tooth 21 and a transmission rod. The planing saw tooth is located at the end of the guide rod 3, and the transmission rod is located inside the guide rod 3 and is movably connected to the guide rod 3 through a bearing structure. The planing saw tooth is connected to one end of the transmission rod, and the bearing structure limits and guides the transmission rod. At the same time, the bearing structure does not occupy the entire cross-sectional space of the guide rod 3 in cross section, thereby providing a flow space for the damaged tissue in the joint and other wastes planed by the planing saw tooth 21 for subsequent negative pressure operations. A driving assembly 5 is provided inside the handle 4, and the driving assembly 5 is detachably connected to the other end of the transmission rod. Such a configuration can correspond to the detachable connection between the guide rod 3 and the handle 4. After the driving assembly 5 is started, it can drive the transmission rod to rotate, and the rotation of the transmission rod can drive the planing saw tooth to perform actual planing operations. Here, the driving assembly 5 is preferably a motor structure.

[0037] The planing assembly 2 with the planing teeth 21 as the main structure can form a planing tool head. The planing tool head is a device used for removing damaged tissues in joints during arthroscopic surgery and has a highly specialized design.

[0038] As an optional embodiment, the guide rod 3 is preferably provided with a connecting clip 31 at one end thereof connected to the handle 4, and the handle 4 is preferably provided with a connecting bayonet 41 at one end thereof connected to the guide rod 3. The connecting clip 31 and the connecting bayonet 41 form a snap connection. The snap connection, as a specific structural form of detachable connection, has sufficient connection strength and is easier to disassemble and assemble.

[0039] As an optional implementation, it also includes a host 6 and a foot switch 7. The host 6 is electrically connected to the drive component 5 and the foot switch 7 through wires, respectively. The foot switch 7 can transmit signals to the host 6, and the host 6 can transmit signals to the drive component 5 to start the drive component 5 or shut down the drive component 5. The foot switch 7 is preferably placed on the ground, and medical staff can control the drive component 5 by stepping on it, which is more convenient and practical.

[0040] As an optional implementation, the RF component 1 includes a RF electrode 11, a first conductive contact 311 is provided on the connecting card 31, the RF electrode 11 is electrically connected to the first conductive contact 311 through a wire, a second conductive contact 411 is provided on the connecting bayonet 41, when the connecting card 31 and the connecting bayonet 41 are in a clamping state, the first conductive contact 311 is electrically connected to the second conductive contact 411, and the second conductive contact 411 is electrically connected to the host 6 through a wire. The above-mentioned arrangement can arrange the circuit of the RF component 1 more reasonably under the condition that the guide rod 3 and the handle 4 are detachably connected;

[0041] The foot switch 7 can transmit a signal to the host 6, and the host 6 can transmit a signal to the RF component 1 to start the RF component 1 or shut down the RF component 1. Medical staff can control the RF component 1 by stepping on it, which is more convenient and practical.

[0042] The radio frequency component 1 with the radio frequency electrode 11 as the main structure can form an arthroscopic radio frequency ablation blade. The arthroscopic radio frequency ablation blade is a medical device used for intra-articular surgery. Its structural design is used to ensure the accuracy and controllability of the surgery. The radio frequency electrode 11 uses directional radio frequency transmission technology to generate high-frequency radio frequency waves at the tip of the electrode in contact with the tissue, which can cause the cells to burst, vaporize and volatilize, thereby achieving precise treatment of the tissue.

[0043] The RF electrode 11 uses bipolar technology, with both the output electrode and the return electrode integrated on the blade, which helps to improve the accuracy and controllability of the surgery;

[0044] The radio frequency electrode 11 can be used for surgical operations on various joints such as the knee joint and the shoulder joint, and has various functions such as cutting, hemostasis, ablation, vaporization, removal and contraction.

[0045] As an optional implementation, a partition is preferably provided at the end of the guide rod 3 away from the handle 4, and the RF electrode 11 and the planing saw teeth 21 are respectively arranged on both sides of the partition. Such an arrangement can further separate the RF electrode 11 and the planing saw teeth 21, forming a more obvious distinction between the two in terms of their setting positions, and at the same time can also reduce the probability of waste generated when one side is working and falling into the other side.

[0046] As an optional embodiment, it also includes a negative pressure component 8, which is arranged at the handle 4. After the negative pressure component 8 is started, it can be connected to an external negative pressure system. The external negative pressure system is a negative pressure system inside the hospital. In clinical practice, it is a routine operation to connect a similar knife head to the external negative pressure system. The negative pressure component 8 preferably includes a negative pressure absorption switch, which is preferably arranged on the handle 4. After the external negative pressure system is connected, the negative pressure absorption switch is pressed by hand to connect the planing component 2 to the external negative pressure system, so that the damaged tissue in the joint and other wastes planed off by the planing teeth 21 can be sucked away by the external negative pressure system.

[0047] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
