Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an endoscopic tissue grasping forceps device and its application for the characteristics of breast tissue. Background Technology

[0002] In the field of minimally invasive laparoscopic breast surgery, tissue grasping forceps are core operating instruments, and their structural rationality and functional adaptability directly affect the safety and efficiency of the surgery. Existing laparoscopic tissue grasping forceps mostly adopt the straight or single-joint design of laparoscopic instruments, failing to fully consider the characteristics of breast tissue—thick glandular tissue, arc-shaped anatomical distribution, and limited surgical space. This leads to a "chopstick effect" during surgery, insufficient instrument maneuverability, and difficulty in accurately adapting to the anatomical angles of different breast regions. This not only increases the difficulty of surgical field exposure but also easily causes traction and compression damage to fragile breast tissue, prolonging the operation time.

[0003] Meanwhile, the electrocautery cutting of tissue during laparoscopic breast surgery generates a large amount of smoke and dust. If this smoke and dust is not removed in time, it will seriously interfere with the clarity of the surgical field. However, most existing grasping forceps do not integrate efficient smoke and dust treatment functions, requiring the additional use of independent negative pressure suction equipment. Frequent instrument changes not only reduce the smoothness of the operation but may also increase the risk of intraoperative infection. Furthermore, tissue debris and bloodstains are easily left on the forceps head after surgery, and the lack of convenient cleaning structure can easily lead to cross-contamination. In addition, some integrated multifunctional laparoscopic instruments have problems such as complex control logic and slow operation response, which makes it difficult to meet the clinical needs of precise and minimally invasive laparoscopic breast surgery. Therefore, developing a laparoscopic tissue grasping forceps device that is adapted to the characteristics of breast tissue, flexible in operation, functionally integrated, and highly safe has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laparoscopic tissue grasping forceps device and its application tailored to the characteristics of breast tissue, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laparoscopic tissue grasping forceps device tailored to the characteristics of breast tissue, comprising: The connecting housing serves as the overall mounting and support carrier for the device. A dual-joint arc-shaped transmission assembly is fixedly connected to the connecting housing, including two symmetrically arranged joint connecting parts and an arc-shaped clamp body. The joint connecting parts drive the arc-shaped clamp body to achieve adaptive angle adjustment of breast anatomy. An electric gripping component, integrated at the distal end of the arc-shaped clamp body, is used for low-damage and precise gripping of breast tissue; An integrated pneumatic drive assembly is embedded inside the connecting housing and includes a pneumatic generating unit and an airflow distribution unit. The pneumatic generating unit generates controllable airflow, and the airflow distribution unit selectively performs surgical field dust adsorption or forceps head cleaning functions. A human-computer interaction control component is disposed on the outer surface of the connecting housing and is used to control the start and stop of each component, parameter adjustment and function switching.

[0006] Preferably, the joint connection includes a proximal joint fixation seat, a distal joint fixation seat, and a joint linkage rotation shaft. The proximal joint fixation seat is fixed to the connecting housing, and the distal joint fixation seat is fixed to the arc-shaped clamp body. The joint linkage rotation shaft passes through the proximal joint fixation seat and the distal joint fixation seat and is driven by a micro motor. The micro motor achieves stepless angle adjustment from 0 to 30° through a human-machine interaction control component.

[0007] Preferably, the arc-shaped forceps body is integrally formed from medical stainless steel, and multiple limiting sleeves are fixedly provided on the outer side of the arc-shaped forceps body. The limiting sleeves are provided with through holes adapted to airflow channels, and the curvature of the arc-shaped forceps body is adapted to the natural anatomical curvature of the breast gland.

[0008] Preferably, the electric gripping assembly includes a connecting sleeve, an electric telescopic rod, a hinge seat, and jaws. The connecting sleeve is fixed to the distal end of the arc-shaped jaw body, and the electric telescopic rod is embedded inside the connecting sleeve. Its output end is hinged to the jaws through the hinge seat.

[0009] Preferably, the air pressure generating unit includes a fixed cylinder, a drive motor, a reciprocating lead screw, a threaded sleeve, and a rubber piston. The fixed cylinder is fixed to the inner side of the connecting housing. The drive motor is installed on the outer side of the fixed cylinder, and its output end is coaxially fixed with the reciprocating lead screw. The threaded sleeve is threadedly engaged with the reciprocating lead screw and fixed to the rubber piston. The rubber piston is in a sealing sliding fit with the inner wall of the fixed cylinder. The cross-sectional area of ​​the fixed cylinder is larger than the cross-sectional area of ​​the connecting pipe.

[0010] Preferably, the airflow distribution unit includes an intake pipe, a first connecting pipe, a three-way valve, a second connecting pipe, and a connecting pipe. The intake pipe and the first connecting pipe are respectively connected to the fixed cylinder, and both are equipped with one-way valves with opposite conduction directions. The first port of the three-way valve is connected to the first connecting pipe, the second port is connected to the flue gas filtration device through the second connecting pipe, and the third port is connected to the annular pipe through the connecting pipe. Both the second connecting pipe and the connecting pipe have built-in electromagnetic control valves.

[0011] Preferably, the outer surface of the connecting tube is connected to a plurality of negative pressure adsorption tubes, the negative pressure adsorption tubes are evenly distributed along the length of the arc-shaped clamp body and the ports face the clamp jaw gripping area, the annular tube is sleeved on the outer periphery of the clamp jaw, and its outer surface is connected to at least two symmetrically arranged cleaning air jet tubes.

[0012] Preferably, the human-machine interface control component includes a speed adjustment knob, a function control button, a trigger switch, and a handle. The speed adjustment knob is electrically connected to the drive motor to achieve stepless adjustment of the motor speed. The function control button includes at least a joint adjustment key, an adsorption start / stop key, and a cleaning start / stop key, which respectively control the working state of the micro motor and the electromagnetic control valve. The handle is hinged to the connecting housing via a connecting shaft, and the abutment plate fixed on its inner side is adapted to the trigger switch. When the handle is pressed, the abutment plate triggers the switch, activating the electric telescopic rod to drive the jaws to close.

[0013] Preferably, a torsion spring is sleeved on the outside of the connecting shaft, with one end of the torsion spring abutting against the connecting housing and the other end abutting against the handle, for automatic reset after the handle is pressed.

[0014] An application of a laparoscopic tissue grasping forceps device tailored to the characteristics of breast tissue includes the following application scenarios: During endoscopic resection of benign breast tumors, a dual-joint arc-shaped transmission component adapts to the arc-shaped anatomical space of the breast, an electric gripping component grips the glandular tissue around the tumor with minimal damage, and a pneumatic pressure generating unit works with a negative pressure adsorption tube to adsorb surgical fumes in real time. During breaks in the surgical procedure, the procedure is switched to the clean channel via a three-way valve. Airflow is then sprayed through the clean jet tube to remove residual tissue debris and bloodstains from the forceps jaws, thus preventing cross-contamination.

[0015] This invention provides a laparoscopic tissue grasping forceps device and its application tailored to the characteristics of breast tissue. It offers the following advantages: 1. This invention, by adding a dual-joint arc-shaped transmission component, enables the arc-shaped forceps body to achieve multi-angle precise adjustment that adapts to the breast anatomy structure. This effectively overcomes the "chopstick effect" that limits the operation of traditional straight or single-joint endoscopic forceps in the narrow surgical space of the breast, significantly improving the device's operational flexibility and accessibility in the arc-shaped anatomical area of ​​the breast. At the same time, the structural design, which is adapted to the characteristics of breast tissue, reduces the traction and compression damage to breast tissue caused by instruments during surgery, significantly optimizes the surgical field exposure, improves the accuracy and safety of surgical operations, and shortens the operation time.

[0016] 2. This invention integrates a pressure-driven component that combines a pressure generating unit and an airflow distribution unit within the connecting housing. The pressure generating unit stably generates controllable airflow, and the airflow distribution unit selectively switches between these components. This allows for precise directional adsorption of surgical field dust and efficient cleaning of forceps head debris during surgery, eliminating the need for separate suction equipment or cleaning tools. This effectively reduces the frequency of instrument changes during surgery, avoids the risk of cross-contamination caused by dust diffusion interfering with the surgical field and residual debris in the forceps head, simplifies the operation process, reduces the surgeon's workload, and balances the smoothness, safety, and cleanliness of the surgery, thus meeting the clinical needs of refined and minimally invasive breast endoscopic surgery.

[0017] 3. This invention integrates human-machine interaction control components on the outer surface of the connecting housing, combining the start / stop control, precise parameter adjustment, and rapid function switching of each component into a single operating interface. This allows operators to easily perform joint angle adaptation, switching between adsorption and cleaning functions, and fine-tuning of drive parameters by adjusting knobs and control buttons without frequently switching operating postures or additionally operating external devices. The linkage design of the handle and trigger switch further simplifies the operation process. Attached Figure Description

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a laparoscopic tissue grasping forceps device for breast tissue characteristics, comprising: Connecting housing 1 serves as the overall mounting and supporting carrier for the device; The dual-joint arc-shaped transmission assembly is fixedly connected to the connecting housing 1, and includes two symmetrically arranged joint connecting parts and an arc-shaped clamp body 3. The joint connecting parts drive the arc-shaped clamp body 3 to achieve adaptive angle adjustment of breast anatomy. The joint connection includes a proximal joint fixation seat 401, a distal joint fixation seat 402, and a joint linkage rotation shaft 403. The proximal joint fixation seat 401 is fixed to the connecting housing 1, and the distal joint fixation seat 402 is fixed to the arc-shaped clamp body 3. The joint linkage rotation shaft 403 passes through the proximal joint fixation seat 401 and the distal joint fixation seat 402 and is driven by a micro motor. The micro motor achieves stepless angle adjustment from 0 to 30° through a human-machine interaction control component.

[0022] Specifically, the joint linkage rotating shaft 403, as the core component for power transmission, uses precision bearings at both ends to form a rotatable fit with the proximal joint fixing seat 401 and the distal joint fixing seat 402, ensuring coaxiality and smoothness during rotation and preventing jamming or offset during angle adjustment. The output torque of the micro motor is rigidly connected to the joint linkage rotating shaft 403 through a coupling. After the motor starts, it drives the shaft to rotate, which in turn drives the distal joint fixing seat 402 to deflect relative to the proximal joint fixing seat 401. Since the proximal joint fixing seat 401 remains fixed to the connecting housing 1, the deflection motion of the distal joint fixing seat 402 is directly transmitted to the arc-shaped clamp body 3 fixed thereto, enabling the arc-shaped clamp body 3 to achieve dynamic adjustment of the bending angle.

[0023] To meet the precise requirements of the curved anatomical space of the breast, the micro-motor is equipped with a high-precision encoder. Combined with pulse signal control from the human-machine interface control components, this ensures that the surgeon can flexibly adjust the curvature of the curved clamp body 3 according to the anatomical angles of the surgical site, such as the upper part of the breast or the inner quadrant. This dual-joint collaborative adjustment structure overcomes the angle limitations of traditional single-joint instruments, allowing the curved clamp body 3 to better conform to the natural anatomical curvature of the breast tissue, effectively avoiding the "chopstick effect" and improving accessibility in confined surgical spaces.

[0024] The curved forceps body 3 is made of medical stainless steel in one piece. Multiple limiting sleeves 13 are fixedly installed on the outer side of the curved forceps body 3. The limiting sleeves 13 have through holes adapted to the airflow channel, and the curvature of the curved forceps body 3 is adapted to the natural anatomical curvature of the breast gland.

[0025] Specifically, the curved forceps body 3 is forged from a single piece of medical-grade 316L stainless steel. This process eliminates structural weaknesses caused by welding seams and avoids incomplete sterilization due to residual contaminants in the seams, fully meeting the clinical requirements for high-pressure steam sterilization of surgical instruments. Its curvature design is based on natural anatomical data of breast tissue, with the radius of curvature precisely controlled between 18 and 22 mm. It can naturally conform to the curved distribution of breast tissue, reducing the contact force between the instrument and the tissue, and structurally avoiding tissue traction damage caused by unsuitable angles in traditional straight forceps bodies.

[0026] An electric gripping assembly is integrated into the distal end of the arc-shaped clamp body 3 for low-damage and precise gripping of breast tissue. The electric gripping assembly includes a connecting sleeve 11, an electric telescopic rod 701, a hinge seat 702, and a clamping jaw 703. The connecting sleeve 11 is fixed to the distal end of the arc-shaped clamp body 3. The electric telescopic rod 701 is embedded inside the connecting sleeve 11, and its output end is hinged to the clamping jaw 703 through the hinge seat 702.

[0027] Specifically, the hinge seat 702 adopts a cross-shaft universal hinge structure, which converts the linear extension and retraction motion of the electric telescopic rod 701 into the opening and closing rotation of the jaws 703. Wear-resistant bushings and damping structures are set at the hinge to make the opening and closing action of the jaws 703 smooth and without impact, while ensuring that the opening and closing angle is linearly related to the travel of the telescopic rod.

[0028] An integrated pneumatic drive assembly is embedded inside the connecting housing 1. It includes a pneumatic generating unit and an airflow distribution unit. The pneumatic generating unit generates controllable airflow, and the airflow distribution unit selectively performs surgical field dust adsorption or forceps head cleaning functions. The air pressure generating unit includes a fixed cylinder 801, a drive motor 805, a reciprocating lead screw 802, a threaded sleeve 803, and a rubber piston 804. The fixed cylinder 801 is fixed to the inner side of the connecting housing 1. The drive motor 805 is installed on the outer side of the fixed cylinder 801, and its output end is coaxially fixed with the reciprocating lead screw 802. The threaded sleeve 803 is threadedly engaged with the reciprocating lead screw 802 and fixed with the rubber piston 804. The rubber piston 804 is in a sealing sliding fit with the inner wall of the fixed cylinder 801. The cross-sectional area of ​​the fixed cylinder 801 is larger than the cross-sectional area of ​​the connecting pipe 808.

[0029] Specifically, the drive motor 805 serves as the power source, driving the reciprocating screw 802 to rotate through precise speed output. Its speed can be steplessly adjusted via the human-machine interface control component, thus enabling flexible adaptation of airflow intensity. The fixed cylinder 801, as a sealed cavity for air pressure generation, is designed with a cross-sectional area larger than that of the connecting pipe 808, which is crucial for airflow acceleration. When the rubber piston 804 moves towards the connecting pipe 808, the space inside the fixed cylinder 801 is compressed, forcing gas into the smaller-diameter connecting pipe 808, significantly increasing the flow rate. When the rubber piston 804 moves in the opposite direction, a negative pressure is created inside the fixed cylinder 801, drawing in sterile air through the air inlet pipe 807 to replenish the airflow. Combined with the reciprocating motion of the piston, continuous and controllable airflow generation is achieved, meeting the power requirements of different surgical scenarios.

[0030] The airflow distribution unit includes an intake pipe 807, a first connecting pipe 808, a three-way valve 901, a second connecting pipe 810, and a connecting pipe 902. The intake pipe 807 and the first connecting pipe 808 are respectively connected to the fixed cylinder 801, and both are equipped with one-way valves 806. The two one-way valves 806 have opposite conduction directions. The first port of the three-way valve 901 is connected to the first connecting pipe 808, the second port is connected to the flue gas filtration device through the second connecting pipe 810, and the third port is connected to the annular pipe 903 through the connecting pipe 902. Both the second connecting pipe 810 and the connecting pipe 902 have built-in electromagnetic control valves. The outer surface of the second connecting pipe 810 is connected to multiple negative pressure adsorption pipes 809. The negative pressure adsorption pipes 809 are evenly distributed along the length of the arc-shaped clamp body 3 and their ports face the gripping area of ​​the clamp jaws 703. The annular pipe 903 is sleeved on the outer periphery of the clamp jaws 703, and its outer surface is connected to at least two symmetrically arranged cleaning jet pipes 904.

[0031] Specifically, the one-way valve 806 in the intake pipe 807 and the connecting pipe 808 constitute a one-way airflow mechanism. The two have opposite directions of conduction, which can strictly control the airflow direction. When a negative pressure is formed in the fixed cylinder 801, only the one-way valve 806 in the intake pipe 807 is open, ensuring that sterile air enters the cavity in one direction to replenish it. When the air pressure in the fixed cylinder 801 increases, only the one-way valve 806 in the connecting pipe 808 is open, so that the compressed airflow is directed to the subsequent channel, avoiding power loss or functional disorder caused by airflow backflow.

[0032] The three-way valve 901, as the core component for function switching, achieves precise on / off switching of the interface through electromagnetic control. Together with the electromagnetic control valves built into connecting pipe 810 and connecting pipe 902, it forms a dual control logic to ensure no cross-flow during function switching. When it is necessary to adsorb smoke and dust from the surgical field, the three-way valve 901 connects connecting pipe 808 and connecting pipe 810, while simultaneously closing the electromagnetic control valve of connecting pipe 902. The airflow is transmitted along connecting pipe 810. The negative pressure adsorption tubes 809, evenly distributed on their outer surface, form a directional negative pressure field because their ports face the gripping area of ​​the forceps 703, precisely capturing the smoke and dust generated during surgery and preventing the smoke and dust from spreading and interfering with the surgical field.

[0033] When cleaning the jaws 703 is required, the three-way valve 901 switches to connect the first connecting pipe 808 and the connecting pipe 902, while closing the solenoid control valve of the second connecting pipe 810. Airflow enters the annular pipe 903, which is fitted around the jaws 703, through the connecting pipe 902. The annular pipe 903 evenly distributes the airflow through symmetrically arranged cleaning jet pipes 904, forming a surrounding jet airflow that fully covers the outer surface of the jaws 703, effectively removing residual tissue debris and blood. Throughout the airflow transmission process, the pipe layout adapts to the arc-shaped jaw body 3, and with the positioning function of the limiting sleeve 13, ensures a stable airflow transmission path without bends or leaks, achieving smooth function switching and reliable results.

[0034] The human-machine interface control component is located on the outer surface of the connecting housing 1 and is used to control the start / stop, parameter adjustment, and function switching of each component. The human-machine interface control component includes a speed adjustment knob 2, a function control button 5, a trigger switch 10, and a handle 6. The speed adjustment knob 2 is electrically connected to the drive motor 805 to achieve stepless adjustment of the motor speed. The function control button 5 includes at least a joint adjustment key, a suction start / stop key, and a cleaning start / stop key, which respectively control the working status of the micro motor and the electromagnetic control valve. The handle 6 is hinged to the connecting housing 1 via a connecting shaft 14. The abutment plate 12 fixed on its inner side is adapted to the trigger switch 10. When the handle 6 is pressed, the abutment plate 12 triggers the switch 10, which activates the electric telescopic rod 701 to drive the jaws 703 to close.

[0035] Specifically, the function control button 5 adopts a grouped design, with the joint adjustment button, adsorption start / stop button, and cleaning start / stop button each corresponding to an independent control loop. Pressing a button triggers the control signal of the corresponding component, enabling instant start / stop of the micro-motor joint angle adjustment and the electromagnetic control valve adsorption and cleaning channel switching. The button uses a self-resetting structure, combined with tactile feedback design, allowing the operator to judge whether the operation is effective by touch, avoiding misoperation due to the operator's line of sight being off-field. The speed adjustment knob 2, as the core component for controlling air pressure intensity, establishes a closed-loop control with the drive motor 805 through pulse signals, precisely controlling the airflow intensity of the air pressure generating unit to meet the power adaptation under different dust levels or cleaning needs.

[0036] The entire assembly is located in an easily accessible area on the outer surface of the connecting housing 1. The speed adjustment knob 2 and the function control button 5 are distributed within the reach of the thumb when holding the handle 6. Parameter adjustment and function switching can be completed without changing the grip posture. With the independent response design of each control circuit, the control commands are accurately transmitted to the corresponding components, which simplifies the operation process and improves the safety and smoothness of operation during surgery.

[0037] A torsion spring is fitted on the outside of the connecting shaft 14. One end of the torsion spring abuts against the connecting housing 1, and the other end abuts against the handle 6, which is used for automatic reset after the handle 6 is pressed.

[0038] Specifically, when the operator presses the handle 6, the handle 6 rotates around the connecting shaft 14, simultaneously compressing the torsion spring to further twist and deform it, thus accumulating elastic potential energy. At this time, the torsion spring generates an elastic restoring force opposite to the pressing direction, always maintaining reverse support for the handle 6. When the operator releases the handle 6, the pressing force disappears, the elastic potential energy stored in the torsion spring is released, pushing the handle 6 to rotate in the opposite direction around the connecting shaft 14 until it returns to the initial gripping position. At the same time, it causes the abutment plate 12 to separate from the trigger switch 10, causing the electric telescopic rod 701 to move in the opposite direction, and the jaws 703 to open automatically.

[0039] An application of a laparoscopic tissue grasping forceps device tailored to the characteristics of breast tissue includes the following application scenarios: During endoscopic resection of benign breast tumors, a dual-joint arc-shaped transmission component adapts to the arc-shaped anatomical space of the breast, an electric gripping component grips the glandular tissue around the tumor with low damage, and a pneumatic pressure generating unit works with a negative pressure adsorption tube 809 to adsorb surgical fumes in real time. During surgical breaks, the three-way valve 901 switches to the clean channel, and the airflow is sprayed through the clean jet pipe 904 to remove residual tissue debris and bloodstains on the surface of the forceps 703, thus avoiding cross-contamination.

[0040] Working principle: When using this device, its operating principle includes the following: An application of a laparoscopic tissue grasping forceps device tailored to the characteristics of breast tissue includes the following application scenarios: During endoscopic resection of benign breast tumors, a dual-joint arc-shaped transmission component adapts to the arc-shaped anatomical space of the breast, an electric gripping component grips the glandular tissue around the tumor with low damage, and a pneumatic pressure generating unit works with a negative pressure adsorption tube 809 to adsorb surgical fumes in real time. During surgical breaks, the three-way valve 901 switches to the clean channel, and the airflow is sprayed through the clean jet pipe 904 to remove residual tissue debris and bloodstains on the surface of the forceps 703, thus avoiding cross-contamination.

[0041] The working principle of this invention is as follows: When it is necessary to adapt to the arc-shaped anatomical space of the breast, the micro motor at the end of the joint linkage rotating shaft 403 is activated by the control button 5 connected to the outer surface of the housing 1. The micro motor drives the joint linkage rotating shaft 403 to rotate, which in turn drives the distal joint fixation seat 402 to rotate relative to the proximal joint fixation seat 401, ultimately changing the bending angle of the arc-shaped clamp body 3, achieving stepless adjustment from 0 to 30°, and precisely adapting to the operational needs of different areas of the breast; the limiting sleeve 13 on the outside of the arc-shaped clamp body 3 plays a positioning and support role for the through airflow channel, preventing the channel from shifting or bending.

[0042] When the operator holds the handle 6, the handle 6 rotates around the connecting shaft 14, and the abutment plate 12 fixed on its inner side contacts the trigger switch 10 on the inner side of the connecting housing 1. The trigger switch 10 sends a signal to activate the electric telescopic rod 701 in the connecting sleeve 11. The telescopic movement of the electric telescopic rod 701 is converted into the opening and closing action of the jaws 703 through the hinge seat 702, so as to achieve precise grasping of breast tissue with low damage. When the operator releases the handle 6, the torsion spring on the outer side of the connecting shaft 14 drives the handle 6 to return to its original position, the abutment plate 12 disengages from the trigger switch 10, the electric telescopic rod 701 moves in the opposite direction, and the jaws 703 open to release the tissue.

[0043] When the electrosurgical cutting generates smoke and dust during surgery, the speed of the drive motor 805 is adjusted by adjusting knob 2. The drive motor 805 drives the reciprocating screw 802 inside the fixed cylinder 801 to rotate. The threaded sleeve 803 reciprocates linearly along the reciprocating screw 802, which in turn drives the rubber piston 804 to slide along the inner wall of the fixed cylinder 801, changing the air pressure inside the fixed cylinder 801. When the rubber piston 804 moves away from the connecting pipe 808, a negative pressure is formed inside the fixed cylinder 801, and the one-way valve 806 in the air inlet pipe 807 is opened, allowing sterile air to enter the fixed cylinder 801. When the rubber piston 804 moves closer to the connecting pipe 808... When the direction is moved, the air pressure inside the fixed cylinder 801 increases, and the one-way valve 806 in the connecting pipe 1 808 is opened. Since the cross-sectional area of ​​the fixed cylinder 801 is much larger than that of the connecting pipe 1 808 and the connecting pipe 2 810, the airflow velocity increases significantly after entering the three-way valve 901 through the connecting pipe 1 808. According to Bernoulli's principle, a negative pressure zone is formed in the connecting pipe 2 810. The electromagnetic control valve built into the connecting pipe 2 810 is opened, and the negative pressure adsorption pipe 809 is evenly distributed along the arc-shaped clamp body 3 with its port facing the clamp mouth 703 gripping area to generate directional suction, which draws in the surgical field smoke and dust and transports it through the connecting pipe 2 810 to the external smoke filtration equipment for purification.

[0044] When the forceps 703 needs to be cleaned during surgical intervals, the electromagnetic control valve of connecting tube 2 810 is closed, while the electromagnetic control valve of connecting tube 902 is opened simultaneously. The controllable airflow generated by the fixed cylinder 801 enters the connecting tube 902 through connecting tube 1 808 and three-way valve 901, and then is diverted to multiple symmetrically arranged jet pipes 904 through the annular pipe 903. The jet pipes 904 surround the outer periphery of the forceps 703, and the airflow is sprayed onto the outer surface of the forceps 703 at an appropriate angle, effectively removing residual tissue debris and bloodstains, avoiding cross-contamination. After cleaning, the airflow naturally diffuses or is discharged through the surgical field drainage channel.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
