Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular to superconducting low-temperature non-stick bipolar forceps. Background Technology
[0002] In minimally invasive surgery, many procedures require cutting human tissue or coagulation, necessitating the use of ablation electrodes. Clinically, ablation electrodes are inserted into the body through a puncture device or other pathway to perform electrocoagulation on the tissue.
[0003] Currently, bipolar forceps are used in clinical practice for electrocoagulation. Bipolar forceps refer to a core structure with two independent forceps arms working together, integrating functions such as precise positioning, insulation protection, and external device compatibility. They can be used for high-frequency electrocoagulation hemostasis and tissue processing in the medical field.
[0004] The prior art provides a bipolar tweezers, including a shell with a mounting block. Left and right tweezers are symmetrically arranged on the mounting block. Guide posts and guide grooves are respectively arranged on the side walls of the left and right tweezers close to each other. The bipolar tweezers device has a guiding function due to the setting of guide posts and guide grooves, which can realize the alignment of the left and right tweezers.
[0005] However, in practical applications, because existing bipolar forceps devices do not have a forceps cooling function, the forceps generate high temperatures under the waveform and energy output by the high-frequency host, which makes them very easy to adhere to human tissue. Summary of the Invention
[0006] To reduce the risk of bipolar forceps adhering to human tissue, this application provides superconducting low-temperature non-stick bipolar forceps.
[0007] The superconducting low-temperature non-stick bipolar tweezers provided in this application adopt the following technical solution: A superconducting low-temperature non-stick bipolar tweezers includes tweezer blades and a fixing shell. Two elastic tweezer blades are arranged opposite each other, and the fixing shell is arranged at one end. The two tweezer blades are clamped and fixed by the fixing shell. Each tweezer blade includes a fixing part, a handle part, a support part and a tweezer tip part, which are connected in sequence. A water supply section is provided between the fixing part, the handle part, the support part and the tweezer tip part. The water supply pipe in the water supply section connects the four parts and connects to the water supply equipment. Cooling water is stored in the water supply pipe to cool the tweezer tip part. The handle has a wire section in the middle, and the output end of the wire section is assembled with the tweezer tip section to connect to a high-frequency device.
[0008] By adopting the above technical solution, a water supply section is set inside the forceps, and a water supply pipe connects the fixing section, handle section, support section, and forceps tip section. Cooling water is delivered into the water supply pipe through an external water supply device, so that the forceps tip can be effectively cooled during operation. This reduces the possibility of the forceps tip becoming too hot and sticking to human tissue under the waveform and energy output of the high-frequency host, thereby reducing the risk during the operation and improving the safety and success rate of the operation. At the same time, the wire section in the middle of the handle section allows the forceps to be easily connected to high-frequency equipment to realize the functions of electrocoagulation hemostasis and tissue processing, meeting the actual needs of minimally invasive surgery.
[0009] Preferably, the fixing shell is provided with an installation joint, and a first through groove and a second through groove are provided on one side of the installation joint. The first through groove and the second through groove are connected to each other. The water supply connector of the water supply part is installed in the first through groove, and the second through groove runs through the fixing part, handle part and support part of the entire tweezer piece. The water supply pipe is stored in the second through groove.
[0010] By adopting the above technical solution, the water supply connector of the water supply part is installed in the first through groove, and the water supply pipe is stored in the second through groove, making the installation of the water supply part more stable, effectively utilizing the space inside the fixed shell, and making the structure of the entire tweezers more compact. At the same time, the second through groove runs through the fixed part, handle part, and support part of the entire tweezers piece, ensuring that the water supply pipe can smoothly connect the various parts and realize the effective delivery of cooling water.
[0011] Preferably, an inlet valve and an outlet valve are installed in the first through groove of the mounting joint. The inlet valve is connected to the water delivery end of the water delivery pipe, and the outlet valve is connected to the water outlet end of the water delivery pipe. The conveying equipment provides cooling water to the water delivery pipe.
[0012] By adopting the above technical solution, an inlet valve and an outlet valve are installed in the first channel, which allows for convenient control of the inflow and outflow of cooling water. When cooling is required, the inlet and outlet valves are opened, allowing cooling water to flow into the water supply pipe and cool the tweezers tip. When cooling is not required or needs to be stopped, the inlet and outlet valves are closed. This configuration provides a continuous flow of cooling water to the water supply pipe, with alternating hot and cold water forming a complete cooling water circulation system. This ensures that the tweezers tip is always within a suitable working temperature range, effectively preventing the tweezers from adhering to human tissue due to prolonged high temperatures.
[0013] Preferably, a third through groove is provided on one side of the mounting connector, the third through groove is located at the bottom of the second through groove, and the wire of the conductor part is stored in the third through groove.
[0014] By adopting the above technical solution, the wire of the conductor section can be stored in the third through groove, which can effectively protect the wire from interference and damage from the external environment. At the same time, the third through groove is located at the bottom of the second through groove, which also makes the structure of the entire tweezers more reasonable and compact.
[0015] Preferably, a mating plate is fixed to one side of the tweezers piece, the length of the mating plate extends from the fixed part of the tweezers piece to the handle part, and a mating clip is fixed to the side of the mating plate near the tweezers piece, the mating clip slidingly engaging in the second through groove.
[0016] By adopting the above technical solution, the mating plate is slidably engaged with the second through groove through the mating strip, thereby achieving a fixed connection between the mating plate and the tweezer piece.
[0017] Preferably, one side of the tweezers piece is fixed with two locking grooves arranged vertically opposite each other. Both locking grooves extend through the entire fixing part and handle part of the tweezers piece, so that the top side of the mating plate engages with one locking groove and the bottom side engages with the other locking groove.
[0018] By adopting the above technical solution, setting up locking slots arranged vertically opposite each other, and locking the top and bottom sides of the mating plate with the two locking slots respectively, the stability of the forceps piece within the fixed shell can be further enhanced, preventing it from shaking or shifting during operation, thereby ensuring the accuracy and safety of the surgery.
[0019] Preferably, two positioning plates are provided between the two tweezer pieces, and a guide component is provided on the positioning plate. One tweezer piece is guided parallel to its adjacent positioning plate through the guide component.
[0020] By adopting the above technical solution, a positioning plate is set between the two forceps blades, and a guide component is used to achieve parallel guidance between the forceps blades and the positioning plate. This allows the two forceps blades to maintain a relatively fixed positional relationship during operation, enabling them to accurately grip and manipulate along a set trajectory. This effectively reduces surgical errors caused by forceps blade positional deviation, improving the accuracy and stability of the surgery. At the same time, this parallel guide design also makes the forceps blades open and close more smoothly, reducing resistance during operation and improving surgical efficiency.
[0021] Preferably, the guide assembly includes an adapter block and a connector plug, wherein the adapter block is installed on the side of the positioning plate near the mating plate and protrudes outward from the side wall of the positioning plate, the connector plug is installed on the side of the mating plate near the positioning plate and protrudes outward from the side wall of the mating plate, and an assembly slot is provided through the middle of the connector plug, and the adapter block is adapted to be inserted into the assembly slot.
[0022] By adopting the above technical solution and utilizing the matching and plugging relationship between the adapter block and the connector, precise guidance and stable connection between the tweezers and the positioning plate can be achieved.
[0023] Preferably, the handle of the tweezers has a guide slot on the side near the mating plate, and a protruding guide block is fixed in the middle of the guide slot. A protruding fixing plug is installed on the side of the mating plate near the tweezers, and an installation slot is provided through the middle of the fixing plug. The guide block is adapted to be inserted into the installation slot.
[0024] By adopting the above technical solution, a guide slot and a guide block are set between the handle and the mating plate. By utilizing the matching relationship between the fixed plug and the mounting slot, the connection stability and guiding accuracy between the tweezers and the mating plate can be further enhanced, thereby ensuring the stability and safety of the tweezers during operation.
[0025] Preferably, an elastic abutment block is fixed to the side of the adapter block near the guide block. When the guide block is adapted to be inserted into the mounting slot, the adapter block is adapted to be inserted into the assembly slot at the same time until the side of the abutment block abuts against the side of the guide block.
[0026] By adopting the above technical solution, an elastic abutment block is provided on the side of the adapter block near the guide block. This provides a certain guiding and shock-absorbing effect. When the guide block is fitted into the mounting slot and the adapter block is fitted into the assembly slot, the abutment block will undergo elastic deformation due to compression, and its side will tightly press against the side of the guide block. This tight pressing not only enhances the connection stability between the forceps blade and the positioning plate and mating plate, preventing loosening of the connection due to instrument shaking or external force during surgery, but also effectively absorbs and buffers the vibration generated during surgery, reducing the impact of vibration on surgical operations. At the same time, the elasticity of the abutment block also provides a certain buffer space for the forceps blade during opening and closing, avoiding jamming or damage caused by rigid connections, improving the service life of the forceps and the smoothness of surgical operations.
[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. A water supply section is set inside the forceps blade. The fixing section, handle section, support section and forceps tip section are connected by a water supply pipe. Cooling water is delivered into the water supply pipe through an external water supply device, so that the forceps tip can be effectively cooled during operation. This reduces the possibility of the forceps tip getting too hot and sticking to human tissue under the waveform and energy output of the high-frequency host, thereby reducing the risk during the operation and improving the safety and success rate of the operation. 2. The wires of the lead wire section are stored in the third through slot, which can effectively protect the wires from interference and damage from the external environment. The wires allow the forceps to be easily connected to high-frequency equipment to realize the functions of electrocoagulation hemostasis and tissue processing, meeting the actual needs of minimally invasive surgery. 3. By utilizing a guide component to achieve parallel guidance between the forceps blades and the positioning plate, the two forceps blades maintain a relatively fixed positional relationship during operation. This allows the two forceps blades to achieve precise clamping and manipulation along a set trajectory, effectively reducing surgical errors caused by forceps blade positional deviation and improving surgical accuracy and stability. At the same time, this parallel guide design also makes the forceps blades open and close more smoothly, reducing resistance during operation and improving surgical efficiency.

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0038] This application discloses superconducting low-temperature non-stick bipolar tweezers.
[0039] Reference Figure 1 and Figure 2 The superconducting low-temperature non-stick bipolar forceps includes forceps blades 1, positioning plates 2, and a fixing shell 3. Two elastic forceps blades 1 are arranged opposite each other, and two positioning plates 2 are arranged between the two forceps blades 1. The positioning plates 2 are equipped with guide components. One forceps blade 1 is guided parallel to its adjacent positioning plate 2 through the guide components. The fixing shell 3 is arranged at one end and can clamp and fix the two forceps blades 1 and the two positioning plates 2. When the two forceps blades 1 are deformed under force and used for clamping, the guide components can provide left and right guidance for the forceps blades 1 that are close to them, which can realize the alignment of the left and right forceps blades 142, prevent skew, and also effectively control the blood vessels from being ruptured due to excessive force and tight closure of the forceps tips, avoiding damage to other parts during operation.
[0040] The forceps unit 1 includes a fixing part 11, a handle part 12, a support part 13, and a forceps tip part 14, which are connected in sequence. A water supply part is provided between the fixing part 11, the handle part 12, the support part 13, and the forceps tip part 14. A water supply tube in the water supply part connects the four parts. There is a wire part in the middle of the handle part 12. The output end of the wire part is assembled with the forceps tip part 14. When using bipolar forceps, a high-frequency device is connected through the wire part, and the power output is activated. The waveform and energy output by the high-frequency device flow through the wire part and are output through the forceps tip part 14 to achieve the surgical effect. At the same time, a water supply device is connected through the water supply part. Cooling water stored in the water supply tube can cool the forceps tip part 14 and prevent adhesion.
[0041] Since the structures and installation methods of the two tweezer pieces 1 are identical, in this embodiment, a detailed description is provided using one tweezer piece 1 and one positioning piece 2 as the installation unit, referring to... Figure 3 and Figure 4The fixed shell 3 is a hollow rectangular shell. The fixed shell 3 has a fixed connector 31 and an installation connector 32 snapped into the middle. The fixed connector 31 includes a ladder block 311 and an I-beam connecting plate 312. One end of the positioning piece 2 is fixedly snapped into the middle of the connecting plate 312. The positioning piece 2 is limited by the two sides of the connecting plate 312 and cannot be removed from the fixed connector 31, but a small amount of sliding travel is allowed. The large end of the ladder block 311 is fixed to the end of the connecting plate 312 away from the positioning piece 2, and the small end of the ladder block 311 is fixedly inserted into the fixed shell 3, thereby realizing the fixation between the positioning piece 2 and the fixed shell 3.
[0042] Two mounting joints 32 are provided inside the fixed housing 3, and the two mounting joints 32 are arranged symmetrically along the center line of the fixed joint 31. Specifically, refer to... Figure 4 and Figure 7 The mounting connector 32 has a first through groove 321, a second through groove 322, and a third through groove 323 extending through the side facing the fixed connector 31. The first through groove 321 and the second through groove 322 are interconnected. The water supply connector of the water supply part is installed through the first through groove 321. The second through groove 322 extends through the fixed part 11, the handle part 12, and the support part 13 of the entire tweezers piece 1. The water supply pipe is stored in the second through groove 322. The third through groove 323 is located at the bottom of the second through groove 322. The wire of the conductor part is stored in the third through groove 323. Through this structural design, the water supply part and the conductor part form an independent and orderly channel layout inside the tweezers piece 1. This ensures that the cooling water can flow smoothly to the tweezers tip 14 for effective cooling, and also ensures that the electrical energy output by the high-frequency equipment is stably transmitted to the tweezers tip 14 through the conductor part, thus realizing the energy supply required for electrocoagulation operation.
[0043] Furthermore, a mating plate 4 is fixed to the side of the tweezers piece 1 near the positioning piece 2. The length of the mating plate 4 extends from the fixing part 11 of the tweezers piece 1 to the handle part 12. During specific installation, a mating retainer 41 is fixed to the side of the mating plate 4 near the tweezers piece 1. The mating retainer 41 slides and engages within the second through groove 322, thereby achieving the assembly between the mating plate 4 and the tweezers piece 1. Moreover, in this application, the water pipe shares an installation through groove with the mating retainer 41. That is, the water pipe passes through and is housed in the first through groove 321 and the second through groove 322. Then, the mating retainer 41 of the mating plate 4 slides and engages within the second through groove 322. This arrangement not only achieves a stable installation of the water pipe but also makes full use of the internal space of the tweezers piece 1, making the overall structure more compact.
[0044] Based on the above structure, a locking groove 15 arranged vertically can be fixed on the side of the tweezer piece 1 near the positioning piece 2. Both locking grooves 15 extend through the fixing part 11 and the handle part 12 of the entire tweezer piece 1, so that the top side of the mating plate 4 is locked with one locking groove 15 and the bottom side is locked with the other locking groove 15, which can further enhance the connection stability between the mating plate 4 and the tweezer piece 1.
[0045] Reference Figure 5 and Figure 6 A guide slot 121 is provided on the side of the handle portion 12 of the tweezers piece 1 near the mating plate 4. The guide slot 121 is a blind groove recessed inward from the outer wall of the tweezers piece 1. A guide block 122 protruding outward is fixed in the middle of the guide slot 121. The guide block 122 can be a rectangular block or a cross-shaped block. The cross-shaped guide block 122 is shown in the accompanying drawings of this application. The size can be adjusted according to actual needs. A fixing plug 42 protruding outward is installed on the side of the mating plate 4 near the tweezers piece 1. The middle of the fixing plug 42 is provided with a mounting slot 421 that matches the guide block 122. When the two are engaged, the guide block 122 is inserted into the mounting slot 421, and the wall thickness of the fixing plug 42 is inserted into the guide slot 121, which further enhances the connection stability between the mating plate 4 and the tweezers piece 1.
[0046] Furthermore, the guide assembly includes an adapter block 21 and a connector plug 43. The adapter block 21 is installed on the side of the positioning piece 2 near the mating plate 4, and the adapter block 21 protrudes outward from the side wall of the positioning piece 2. The adapter block 21 can be a rectangular block. The connector plug 43 is installed on the side of the mating plate 4 near the positioning piece 2, and the connector plug 43 protrudes outward from the side wall of the mating plate 4. The middle of the connector plug 43 has a through-hole assembly slot 431 that matches the shape and size of the mounting slot 421. During installation, the adapter block 21 is inserted into the assembly slot 431 until the side of the adapter block 21 abuts against the side of the guide plug 122.
[0047] Based on the above structure, an elastic abutment block 22 can be fixed to the side of the adapter block 21 near the guide plug 122, so that the side of the abutment block 22 abuts against the side of the guide plug 122. Since the mating plate 4 is provided with a fixing plug 42 and a connecting plug 43, the mounting slot 421 in the middle of the fixing plug 42 and the assembly slot 431 in the middle of the connecting plug 43 pass through and form a mounting cavity, providing sufficient installation space for the cooperation of the adapter block 21, the abutment block 22 and the guide plug 122.
[0048] The contact block 22 can be made of rubber. When the adapter block 21 is inserted into the mounting slot 431, the contact block 22 will be compressed and undergo elastic deformation, thereby generating a reverse elastic force. This elastic force not only makes the connection between the adapter block 21 and the mounting slot 431 tighter, preventing loosening during use, but also plays a certain role in cushioning, reducing damage to the overall structure of the tweezers caused by external forces such as vibration. At the same time, this elastic contact design also makes the tweezers easier to assemble and disassemble. By simply applying a certain external force to overcome the elastic force of the contact block 22, the adapter block 21 can be easily removed from or inserted into the mounting slot 431.
[0049] Reference Figure 3 and Figure 7 The tweezers tip 14 includes a hollow support arm 141 and a tweezers blade 142 welded and fixed to the support arm 141. The support arm 141 is detachably fixed to the support part 13. Specifically, the support part 13 can be welded to the output end of the handle part 12, and then the support arm 141 can be threaded onto the support part 13. Alternatively, the support arm 141 can be locked onto the support part 13 with screws. The tweezers blade 142 is welded to the end of the support arm 141.
[0050] The forceps 142 is made of stainless steel and coated with an anti-stick coating. The forceps 142 is electrically connected to the wire. When the power output is activated, the waveform and energy output by the high-frequency device flow through the forceps 142 through the wire to achieve the surgical effect. The anti-stick coating can prevent tissue adhesion when the forceps 142 comes into contact with human tissue.
[0051] Repeat the assembly of another mounting unit consisting of tweezers piece 1 and positioning piece 2.
[0052] Reference Figure 1 and Figure 8 Anti-scalding plates 51 are fixed to the outer walls of the forceps piece 1, the mating plate 4, and the positioning plate 2. A soft rubber sleeve 52 is also fixed to the exposed outer walls of the fixing part 11 and the handle part 12 of the forceps piece 1. These three anti-scalding plates 51 together form a comprehensive anti-scalding protective layer. Even during prolonged use, when the forceps piece 1 generates heat due to high-frequency energy transmission, these anti-scalding plates 51 can effectively prevent heat transfer to the hands of medical personnel, greatly reducing the risk of burns. The soft rubber sleeve 52 further enhances grip comfort; its soft material conforms to the curves of the hand, reducing fatigue from prolonged operation. Moreover, the soft rubber sleeve 52 also has a certain anti-slip function, ensuring that medical personnel can firmly hold the forceps during surgery, preventing slippage that could affect surgical precision. Anti-slip textures are also provided on the handle part 12 of the forceps piece 1; these textures, in conjunction with the soft rubber sleeve 52, further enhance grip stability.
[0053] In this application, an inlet valve and an outlet valve are installed in the first through groove 321 of the mounting connector 32. The inlet valve is connected to the water supply end of the water supply pipe, and the outlet valve is connected to the water outlet end of the water supply pipe. This can provide flowing cooling water to the water supply pipe. The alternation of hot and cold water forms a complete cooling water circulation system, ensuring that the tip of the tweezers 14 is always in a suitable working temperature range, effectively preventing the tweezers 142 from sticking to human tissue due to prolonged high temperature.
[0054] Working principle of the invention: The mating strip 41 of the mating plate 4 is slidably engaged in the second through groove 322 of the tweezer piece 1; the top and bottom sides of the mating plate 4 are respectively engaged in the upper and lower engagement grooves 15 of the tweezer piece 1, and at the same time, the guide plug 122 of the handle part 12 of the tweezer piece 1 is adapted to be inserted into the fixing plug 42 of the mating plate 4, and the wall thickness of the fixing plug 42 is inserted into the guide slot 121 of the tweezer piece 1, thereby realizing the connection between the mating plate 4 and the tweezer piece 1.
[0055] One end of the positioning piece 2 is snapped into the middle of the I-beam connecting plate 312 of the fixed joint 31. It is limited by both sides of the connecting plate 312 and cannot be dislodged, but a small amount of sliding is allowed. The ladder block 311 of the fixed joint 31 is fixedly inserted into the fixed shell 3, thereby fixing the positioning piece 2 to the fixed shell 3.
[0056] The connecting plug 43 on the side of the mating plate 4 near the positioning piece 2 is inserted and connected to the adapter block 21 of the positioning piece 2 until the side of the contact block 22 abuts against the side of the guide plug 122. The mounting slot 421 in the middle of the fixed plug 42 and the assembly slot 431 in the middle of the connecting plug 43 pass through and form an installation cavity, providing sufficient installation space for the cooperation of the adapter block 21, the contact block 22 and the guide plug 122, and enhancing the tightness of the connection between the structures.
[0057] During the surgery, the lead wire is connected to the high-frequency device. After the power output is activated, the waveform and energy output by the high-frequency device flow through the lead wire and the forceps 142 of the forceps tip 14 to provide the energy required for the electrocoagulation operation. At the same time, the water supply unit is connected to the water supply equipment, and the inlet and outlet valves are opened to allow cooling water to flow in the water supply pipe, forming a complete cooling water circulation system. The cooling water flows along the water supply pipe to the forceps tip 14 to cool the forceps 142, which can effectively prevent the forceps 142 from adhering to human tissue. The positioning plate 2 can also effectively control the situation where the blood vessel is ruptured due to excessive force causing the forceps tip to close too tightly, thus avoiding damage to other parts during the operation and ensuring the smooth progress of the surgery.
[0058] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
