Description

Technical Field

[0001] This invention relates to the field of intelligent recognition technology, and in particular to an intelligent scalpel handle for surgical robots. Background Technology

[0002] In recent years, with the rapid advancement of informatization and refined management in the medical industry, the demand for intelligent and traceable surgical instruments has been increasing. Traditional methods relying on manual identification and paper records are no longer sufficient to meet the requirements of modern hospitals for full lifecycle management of instruments. Especially in reusable surgical instruments, achieving unique identification, sterilization status verification, usage monitoring, and information system integration has become a key technological bottleneck in this field. Therefore, surgical instruments integrating intelligent identification technologies such as RFID (Radio Frequency Identification) have gradually become a research hotspot. Related products are continuously developing towards "high-temperature resistance, structural stability, information integration, and safety and reliability," propelling surgical instruments from "usable" to a new era of intelligent control and traceability.

[0003] In existing technologies, medical cutting and retrieval tools are often made of traditional metal materials, such as stainless steel, and the manufacturing process is relatively mature to meet the needs of routine surgical cutting. Their designs are mostly general standard styles, with relatively fixed blade shapes and tool structures, relying on manual operation by medical personnel or control by simple mechanical devices.

[0004] While these types of blades can handle most common surgical scenarios, they have significant limitations. In delicate surgeries, such as ophthalmology and neurosurgery, the insufficient precision of the blades makes it difficult to accurately cut tiny tissues, easily damaging surrounding fragile tissues. For complex lesions, such as irregularly shaped tumors, standard blades cannot conform to the lesion's contour, increasing the difficulty and risk of the surgery. Furthermore, there is a lack of effective and convenient rapid inspection methods after the use of traditional blades. Current methods rely heavily on manual visual inspection or simple measuring tools, making it difficult to detect minute damage such as microscopic wear and nicks on the blade. These defects can lead to poor cutting results in subsequent surgeries, affecting surgical quality and postoperative recovery.

[0005] The tool holders in the prior art have the following drawbacks: 1. Lack of individual identification ability, resulting in low management efficiency: Ordinary surgical scalpels cannot be uniquely identified, making it difficult for hospitals to individually number or track each scalpel. The management of medical device circulation, usage records, and sterilization cycles relies on manual registration, which is prone to errors or omissions. It is difficult to achieve automated inventory management, surgical record traceability, and accountability tracking.

[0006] 2. Lack of information technology tracking capabilities makes risk difficult to control: Once problems such as broken knives, misuse, or ineffective disinfection occur, it is difficult to quickly pinpoint the responsible party. The lack of records on the number of times reusable knives are used may lead to the risk of exceeding the expiration date or cross-infection.

[0007] 3. The structure is incompatible with the information system: Ordinary cutting tool structures do not have reserved space for installing information components and cannot directly integrate identification modules such as RFID; Even if labels are forcibly attached, the high temperature and humidity environment during the sterilization process can cause the information labels to fall off, become invalid, or be damaged.

[0008] 4. Cannot adapt to high-temperature and high-pressure sterilization environments: Conventional electronic tags or barcode tags are extremely prone to failure under high temperature and pressure; If unprotected electronic components are embedded in the handle or tip of a scalpel, they are easily damaged by high temperatures, making it impossible to read the information repeatedly.

[0009] 5. Traceability systems rely on external equipment, resulting in poor flexibility: Some solutions attempt to track surgical instruments through external trays or labels inside packaging boxes, but these labels cannot be linked to specific instruments. Once a knife is removed from its packaging or pallet, it cannot be identified independently, affecting the efficiency and accuracy of tracking in actual operation.

[0010] In summary, the existing tool holders and tools have the following problems: 1. Unable to achieve individual device identification and information management: Traditional surgical scalpels have a uniform shape and lack unique identification markings, making it difficult for hospitals to accurately record, track, and manage the lifecycle of each scalpel in actual management, resulting in low levels of informatization and difficulties in traceability.

[0011] 2. High safety risks associated with reusing medical devices Reusable surgical scalpels are difficult to record in terms of usage and sterilization, which may lead to overuse or incomplete cleaning, causing medical safety hazards such as cross-infection and surgical accidents.

[0012] 3. The tool information cannot be integrated with the hospital information system. Currently, surgical scalpels cannot achieve data interaction with HIS (Hospital Information System) and SPD (Supply Chain Management) systems, and do not support automatic barcode scanning registration, intelligent verification, and real-time traceability. Summary of the Invention

[0013] To address the aforementioned issues, this invention proposes an intelligent scalpel handle for surgical robots. This intelligent scalpel handle enables centralized management of surgical tools, precise recording, tracking, and lifecycle management of the tools. It can record the number of times the tools are used and their sterilization status, and interact with the corresponding control system. To achieve the above objectives, the technical solution adopted by the present invention is as follows: A smart scalpel handle for surgical robots, including The scalpel holder has a first connecting structure at its tail for mounting the scalpel handle entirely onto the actuator of the surgical robot, and a second connecting structure at its front for connecting the scalpel handle rod. The tool holder has a tail portion that is detachably connected to the tool holder seat via a second connecting structure, and a front portion that has a mounting structure for connecting a tool. A cutting tool, which is connected to the front end of a tool holder via a mounting structure; An RFID identification device is installed inside one of the tool holders or tool holders, and an RFID passive chip corresponding to the basic information of the mounting base is installed inside the other of the tool holders or tool holders. Once the tool holder and the tool holder shaft are accurately aligned, the RFID identification device can communicate with and identify the RFID passive chip.

[0014] Preferably, the tool holder is equipped with an RFID identification device, and the tool holder bar is equipped with an RFID passive chip.

[0015] Preferably, the RFID identification device is located near the RFID passive chip after the tool holder and the tool holder are accurately aligned.

[0016] Preferably, the first connection structure is a flange, and the flange has a plurality of first threaded holes arranged in an array with the flange axis as the center.

[0017] Preferably, an annular groove structure is formed between the main body of the tool holder and the flange, so that the front end face of the flange is spaced apart from the main body of the tool holder.

[0018] Preferably, the passive RFID chip is surrounded by an asbestos pad that provides heat insulation and shock absorption.

[0019] Preferably, the passive RFID chip is a high-temperature resistant ceramic-encapsulated chip.

[0020] Preferably, the front part of the tool holder is provided with two movable blocks that can move together, and each movable block is provided with a second threaded hole corresponding to the position. The cutting tool is clamped and connected by tightening the clamping movable block with screws.

[0021] The beneficial effects of using this invention are: The intelligent tool holder in this invention employs RFID identification technology, with RFID identification devices and passive RFID chips correspondingly installed in the tool holder base and the tool holder shaft. The following effects are achieved through RFID identification technology: 1. RFID chip embedded structure design: The handle has a pre-reserved groove in the middle, which is specifically designed to accommodate an RFID chip; the chip and the blade body form an integrated structure, which does not affect the surgical operation.

[0022] 2. High-temperature insulation and protection structure: The RFID chip is wrapped with asbestos or other high-temperature insulation materials; the outer layer uses a high-temperature ceramic cap to seal the chip module, achieving functional protection in high-temperature steam environments.

[0023] 3. Integrated design for tool information management: The RFID chip is pre-set with information such as the tool number, model, size, production date, and sterilization status; it supports integration with hospital HIS / medical device management systems to achieve usage records, cleaning tracking, and lifecycle management.

[0031] This embodiment proposes an intelligent scalpel handle for a surgical robot, comprising three main parts: a handle base 1, a handle rod 2, and a cutting tool 3. The handle base 1 has a first connecting structure at its tail for mounting the entire handle to the actuator of the surgical robot, and a second connecting structure (in this embodiment, a mounting groove 15) at its front for connecting the handle rod 2. The tail of the handle rod 2 is detachably connected to the handle base 1 via the second connecting structure, and the front of the handle rod 2 has a mounting structure for connecting the cutting tool 3. The cutting tool 3 is connected to the front end of the handle rod 2 via the mounting structure. The handle base 1, handle rod 2, and cutting tool 3, when connected together, form a... Figure 1 The state shown.

[0032] like Figure 2 As shown, the tool holder 1 is equipped with an RFID identification device 11, and the tool holder 2 is equipped with an RFID passive chip 21. When the tool holder 1 and the tool holder 2 are accurately connected, the RFID identification device 11 can communicate with and identify the RFID passive chip 21.

[0033] In this embodiment, both the scalpel holder 1 and the scalpel handle 2 are cylindrical and made of corrosion-resistant metal. An RFID passive chip 21 is embedded in the center of the handle 2 to record basic information about the scalpel, including serial number, material, manufacturing batch, and length. An asbestos pad is wrapped around the chip inside the handle 2 to provide heat insulation and impact cushioning. The chip is encapsulated in a high-temperature ceramic structure on the outside of the handle 2 to ensure it maintains its functionality under high temperature and pressure (such as high-temperature steam sterilization).

[0034] like Figure 3 As shown, the tail of the scalpel holder 1 has a first connecting structure for mounting the scalpel handle to the actuator of the surgical robot. In this embodiment, the first connecting structure is a flange 12, which has several first threaded holes 13 arranged in an array around the axis of the flange 12. An annular groove 14 is formed between the body of the scalpel holder 1 and the flange 12 to space the front end face of the flange 12 from the body of the scalpel holder 1. The scalpel holder 1 is equipped with an RFID identification device 11, which includes various identification and signal processing circuits. It communicates with the passive RFID chip 21 in the middle of the scalpel handle 2 to achieve information exchange.

[0035] like Figure 4As shown, the front part of the tool holder 2 is provided with two movable blocks 22 that can move together. Both movable blocks 22 are provided with second threaded holes 23 corresponding to the position. The tool 3 is clamped and connected by tightening the movable blocks 22 with screws.

[0036] In this embodiment, the intelligent scalpel handle is used in hospital operating rooms. It can be repeatedly sterilized under high temperature and pressure. The handle is made of titanium alloy (such as Ti-6Al-4V), CNC machined as a whole, with a robust structure, rust resistance, and high temperature resistance. Blade interface: Standard No. 3 universal interface, replaceable blade, compatible with various models. RFID chip: Uses a high-temperature resistant packaged passive chip (industrial-grade packaging, glass shell), operating at a frequency of 13.56 MHz. Chip location: Embedded in a groove in the middle of the handle, surrounded by a high-density asbestos gasket. Packaging method: The chip is pressed tightly by a ceramic sealing sheet and further secured with screws and sealant to ensure that its function remains intact after high temperature and pressure sterilization.

[0037] This smart scalpel handle can be reused more than 50 times. Before and after each surgery, information such as instrument usage time, surgical department, and number of uses is recorded by scanning a code. It can be connected to the hospital information system (HIS) and material management system to achieve refined life cycle management of instruments, save instrument management costs, and improve sterilization safety.

[0038] This intelligent scalpel handle effectively improves the level of intelligent management of surgical instruments 3, reduces the risk of errors in manual recording, enhances the hospital's instrument management and infection control capabilities, avoids the risk of using unsterilized instruments or mixing instruments 3, and improves the traceability of reused instruments.
