Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a visual, minimally invasive pre-coagulation fragmentation system for large, highly vascularized tumors. Background Technology

[0002] Large or highly vascularized tumors (such as those in the pelvis, retroperitoneum, abdominal cavity, mediastinum, and deep soft tissue / bone) are often closely adjacent to critical structures such as the ureter, bladder, intestines, and important blood vessels and nerves, compressing or even adhering to these tissues. Furthermore, the tumors are rich in blood sinuses, posing a high risk of bleeding. Current mainstream surgical strategies often involve extensive and complete resection of the tumor from its periphery. Such surgeries typically require careful dissection of surrounding organs, blood vessels, and nerves outside the tumor capsule, which can easily lead to: ① accidental injury to organs or blood vessels / nerves during dissection; ② massive intraoperative bleeding and obscured surgical field due to the tumor's high blood supply; ③ prolonged surgical time, enlarged incisions (often exceeding 50 cm), and increased complications.

[0003] To reduce bleeding and procedural risks, clinical practice may combine preoperative embolization and intraoperative hemostasis (monopolar / bipolar electrocoagulation, ultrasonic scalpel, etc.). However, surgeries on these large, highly vascularized tumors remain extremely risky, with a long learning curve. Only a few dozen hospitals nationwide have senior physicians with the capability and qualifications to perform such surgeries. This makes the treatment of these patients a serious problem both nationally and globally.

[0004] Currently, some devices attempt to achieve internal tumor inactivation and hollowing, but they have significant drawbacks: First, existing endoscopes are mostly used for intracavitary observation, and surgical instruments, electrocoagulation instruments, and fragmentation / suction instruments often need to be separated or frequently changed, making it difficult to form a continuous and stable closed-loop operation; Second, direct mechanical fragmentation or cutting of highly vascularized tumor tissue can easily cause continuous bleeding, and blood and electrocoagulation fumes can quickly contaminate the lens and obstruct the field of vision; Third, the uneven size of the fragmented tissue blocks can easily clog the suction tubing, resulting in low drainage efficiency and the need for repeated withdrawal and cleaning; Fourth, there is a lack of systematic structural design and control logic for the "first hemostasis / pre-coagulation - then fragmentation - simultaneous drainage - simultaneous clearing of vision" process.

[0005] Therefore, there is an urgent need for a closed-loop minimally invasive treatment system that can enter the tumor through the skin or a small incision, perform controlled pre-coagulation hemostasis and inactivation of the tissue under visualization, then mechanically dissect the coagulated tissue, and simultaneously drain it through continuous coaxial negative pressure drainage, while also achieving continuous clearing of vision with spray irrigation. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a visualized, minimally invasive pre-coagulation fragmentation system for large, highly vascularized tumors.

The second motor and the regulating components are both electrically connected to the control system.

[0009] Furthermore, the adjustment component is a lead screw adjustment mechanism, and the upper part of the second motor is fixedly connected to the lead screw nut seat in the lead screw adjustment mechanism.

[0010] Furthermore, a hand-held component is fixedly provided at the bottom of the handle; The handheld device has a power supply fixedly installed inside, which is electrically connected to the control system.

[0011] Furthermore, a first motor switch and a second motor switch are fixedly provided at the bottom of the handle, and the first motor switch and the second motor switch are electrically connected to the control system respectively.

Compared with the prior art, the present invention, employing the above technical solution, has the following technical advantages: The integrated electrocoagulation and fragmentation components enable a minimally invasive procedure for large, highly vascularized tumors, allowing for pre-coagulation followed by fragmentation, significantly reducing the risk of intraoperative bleeding. In the electrocoagulation component, the first and second clamping arms are fully retracted within the functional head's receiving cavity when not in use, preventing damage to surrounding tissue during insertion and removal.

Combined with the injection and aspiration connectors, fluid can be injected and residue aspirated simultaneously during fragmentation. A camera and light source provide real-time visual feedback, and with the data transmission connector connecting to an external display device, the surgeon can clearly observe the coagulation boundary and fragmentation progress.

[0018] The technical solutions of 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.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention. Example

[0021] This embodiment provides a visual minimally invasive pre-coagulation fragmentation system for large, highly vascularized tumors, comprising: a handle 1, an outer sheath 2, a functional head 3, an electrocoagulation component 4, a fragmentation component 5, and a control system 6. The handle 1 has a fixed injection connector 11 at its proximal end (the end closest to the operator). The injection connector 11 is a Luer connector or quick-connect connector, used for detachable connection to an external injection device (such as a syringe or infusion pump). During the procedure, saline, hemostatic agents, or cooling fluid can be injected into the tumor area through the injection connector 11 to achieve irrigation, cooling, or auxiliary hemostasis. The outer sheath 2 is a rigid hollow tube, with its proximal end fixed to the distal end of the handle 1 (the end furthest from the operator). The distal end of the outer sheath 2 is fixedly connected to the functional head 3. The length and diameter of the outer sheath 2 are designed according to clinical needs, typically with an outer diameter not exceeding 10 mm. The functional head 3 has an internal receiving cavity; the distal end of the functional head 3 (i.e., the front end entering the body) has: a first through groove 31, a second through groove 32, and a third through groove 33. The first through slot 31 is used for extending or retracting the clamping arm in the coagulation assembly 4. The second through slot 32 is used for extending or retracting the inner sheath tube 51 and the disintegration stirring head 52 in the disintegration assembly 5. The third through slot 33 is connected to the liquid injection connector 11 through the pipeline 111 and is used to guide the liquid to the target area. The distal end of the functional head 3 is also fixedly equipped with a camera 34 and a light source 35. The camera 34 is a miniature high-definition camera (such as a CMOS image sensor), and the light source 35 is an LED light source. The two work together to visualize the surgical area.

[0022] To prevent blood or tissue debris from contaminating the lens, a transparent protective cover is fitted over the lens of camera 34, and the protective cover is fixedly connected to the distal end of functional head 3. The image signal acquired by camera 34 is transmitted to control system 6, and then output to external display device through data transmission connector 7. Control system 6 is fixedly installed inside handle 1 and includes: microcontroller, drive circuit and signal processing module; control system 6 is electrically connected to the first motor 44 and telescopic device 45 in electrocoagulation assembly 4, the second motor 54 and adjustment component 55 in fragmentation assembly 5, as well as camera 34 and light source 35, for receiving commands from operating switches and control components. Electrocoagulation assembly 4 includes: first clamping arm 41, second clamping arm 42, support base 43, first motor 44 and telescopic device 45. Both first clamping arm 41 and second clamping arm 42 are movably inserted into first through groove 31 and can slide axially. The first clamping arm 41 is fixedly provided with a hinge seat 411 at its proximal end, and the second clamping arm 42 is fixedly provided with a gear seat 421 at its proximal end; the first clamping arm 41 and the second clamping arm 42 are hinged at the hinge seat 411 to form a structure similar to a jaw, which can be opened and closed relative to each other.

[0023] In this embodiment, the telescopic device 45 is preferably a miniature electric push rod or a linear stepper motor, and the telescopic device 45 is fixedly installed in the receiving cavity of the functional head 3.

[0024] The output end of the telescopic device 45 is fixedly connected to the proximal end of the support seat 43, and is used to drive the support seat 43 and the clamping arm of the entire electrocoagulation assembly 4 to move back and forth; the support arm 451 is fixedly provided on both sides of the far end of the support seat 43, and the far end of the support arm 451 is fixedly connected to the hinge seat 411.

[0025] The first motor 44 is fixedly mounted on the support base 43, and its output end is provided with a drive gear, which meshes with a rack or sector gear on the gear seat 421. When the first motor 44 rotates forward, the drive gear drives the gear seat 421 to close the second clamping arm 42 relative to the first clamping arm 41; when the first motor 44 rotates in reverse, the second clamping arm 42 opens.

[0026] Electrocoagulation electrode pads are fixedly mounted on opposite sides of the distal ends of the first clamping arm 41 and the second clamping arm 42. These electrocoagulation electrode pads are electrically connected to the control system 6 via wires. An electrode activation button is also fixedly mounted on the upper part of the handle 1, and this button is electrically connected to the control system 6. When the clamping arm clamps the tumor tissue, the control system 6 outputs high-frequency electrical energy to the electrocoagulation electrode pads to pre-coagulate the clamped area, causing vascular occlusion and achieving hemostasis and inactivation.

[0027] It should be further explained that, in the initial non-working state, the first clamping arm 41 and the second clamping arm 42 of the entire electrocoagulation assembly 4 are completely retracted into the receiving cavity of the functional head 3 and do not protrude from the first through slot 31.

[0028] The fragmentation assembly 5 includes: an inner sheath 51, a fragmentation stirring head 52, a liquid suction connector 53, a second motor 54, and an adjustment assembly 55.

[0029] The inner sheath tube 51 is a hollow rigid tube, with its distal end movably inserted into the second through groove 32, and its proximal end passing through the inner cavity of the outer sheath tube 2 and the handle 1 and being fixedly connected to the liquid suction connector 53.

[0030] The suction connector 53 is movably located at the proximal end of the handle 1, and one side of its interface is a Luer connector for detachable connection with an external suction device (such as a negative pressure suction device).

[0031] The suction connector 53 can slide within a certain range. A through groove is provided at the bottom of the near end of the handle 1 for the suction connector 53 to slide, so as to ensure that the suction connector 53 can move synchronously when the inner sheath tube 51 extends and retracts.

[0032] The adjustment component 55 is fixedly disposed at the proximal end of the handle 1. In this embodiment, the adjustment component 55 is a lead screw adjustment mechanism, including a lead screw, a lead screw nut seat, and a drive motor (or manual knob); the upper part of the second motor 54 is fixedly connected to the lead screw nut seat. When the lead screw rotates, the lead screw nut seat drives the second motor 54, the liquid suction connector 53, and the inner sheath tube 51 to move axially together, thereby realizing the extension and retraction of the inner sheath tube 51 and the disintegrating stirring head 52.

[0033] The second motor 54 is fixedly installed inside the adjustment assembly 55. The output end of the second motor 54 is a long shaft that passes through the liquid suction connector 53 and extends into the lumen of the inner sheath tube 51.

[0034] The fragmentation stirring head 52 is rotatably disposed within the distal lumen of the inner sheath 51, and its proximal end is fixedly connected to the output end of the second motor 54. When the second motor 54 rotates at high speed, the fragmentation stirring head 52 rotates accordingly, mechanically fragmenting the pre-coagulated tumor tissue.

[0035] In the non-working state, the inner sheath 51 and the disintegrating stirring head 52 are also completely housed in the receiving cavity of the functional head 3, without protruding from the second through groove 32. In the non-working state, the distal end of the inner sheath 51 (such as the suction port) is located in the second through groove 32, so that suction operation can still be performed through the inner sheath 51 and the suction connector 53 even when the disintegrating stirring head 52 is not used. A rubber ring is fixedly provided on the inner wall of the second through groove 32, and the rubber ring is sealed to the side wall of the distal end of the inner sheath 51.

[0036] A handheld part 13 is fixedly installed at the bottom of the handle 1. The handheld part 13 is an ergonomic grip. A power source (such as a rechargeable battery) is fixedly installed inside the handheld part 13. The power source is electrically connected to the control system 6 to supply power to the entire system.

[0037] A first motor switch 14 and a second motor switch 15 are fixedly installed at the bottom of the handle 1. The first motor switch 14 and the second motor switch 15 are electrically connected to the control system 6. The first motor switch 14 is used to control the rotation and stop of the first motor 44, thereby realizing the clamping and opening of the first clamping arm 41 and the second clamping arm 42. The second motor switch 15 is used to control the start and stop of the second motor 54, realizing the rotation and crushing of the crushing and stirring head 52.

[0038] A first control element 16 and a second control element 17 are fixedly disposed on one side of the handle 1. The first control element 16 and the second control element 17 are electrically connected to the control system 6. The first control element 16 is used to control the extension and retraction of the telescopic device 45, thereby realizing the overall extension and retraction of the first clamping arm 41 and the second clamping arm 42. The second control element 17 is used to control the forward and backward movement of the adjusting assembly 55 (screw adjusting mechanism), thereby realizing the extension and retraction of the inner sheath tube 51 and the crushing and stirring head 52.

[0039] A data transmission connector 7 (such as a USB interface, HDMI interface, or wireless transmission module) is also fixedly installed at the bottom of the handle 1. The data transmission connector 7 is electrically connected to the control system 6 and signal-connected to an external display device (such as a medical monitor or tablet computer). The real-time images captured by the camera 34 are processed by the control system 6 and output to the external display device through the data transmission connector 7, allowing the surgeon to observe the tumor tissue boundary, clamping position, coagulation state, and fragmentation process.

[0040] When using: First, connect the injection connector 11 to the injection device containing saline or hemostatic solution, connect the suction connector 53 to the negative pressure suction device, and connect the data transmission connector 7 to the external display device. At this time, the first clamping arm 41, the second clamping arm 42, the inner sheath 51, and the disintegrating and stirring head 52 are all in the retracted state and are all located in the receiving cavity of the functional head 3.

[0041] Then, the outer sheath 2 and the functional head 3 are directly punctured or pushed into the tumor through the incision.

[0042] Under real-time visual guidance, the surgeon confirms that the tumor tissue is located in front of the functional head 3. The surgeon rotates the first control component 16 forward, and the control system 6 drives the telescopic device 45 to extend, pushing the support seat 43, support arm 451 and hinge seat 411 forward, so that the first clamping arm 41 and the second clamping arm 42 extend from the first through groove 31 until they reach both sides of the tumor tissue to be treated.

[0043] Next, the operator operates the first motor switch 14 to the "closed" position. The first motor 44 rotates forward, driving the second clamping arm 42 to close via the gear seat 421, thus clamping the tumor tissue together with the first clamping arm 41. At this time, the operator can adjust the clamping force through the first motor switch 14. After confirming stable clamping, the operator activates the electrocoagulation electrode pads via the electrode activation button on the handle to pre-coagulate the clamped area.

[0044] Since the camera 34 and the light source 35 are located at the far end of the functional head 3, and the lens has a transparent protective cover, the small amount of smoke generated by electrocoagulation can be drawn away and removed through the inner sheath tube 51 and the liquid suction connector 53, maintaining a clear field of vision. After pre-coagulation is completed, the electrocoagulation is turned off, the clamping arm is opened by the first motor switch 14, and the telescopic device 45 is retracted by controlling the "retract" direction of the first control component 16, so that the clamping arm is retracted back into the functional head 3.

[0045] After pre-coagulation, the surgeon controls the "extension" direction of the second control component 17, which in turn controls the adjustment component 55 (screw adjustment mechanism) to drive the second motor 54, inner sheath 51, and disintegrating stirring head 52 to extend from the second through-slot 32, allowing their distal ends to enter the coagulated tumor tissue. Then, the surgeon presses the second motor switch 15 and adjusts it to a suitable speed. The second motor 54 rotates, driving the disintegrating stirring head 52 to rotate, mechanically disintegrating the coagulated tumor tissue into fine particles.

[0046] During the fragmentation process, the injection device (through injection connector 11 and tubing 111) is simultaneously activated to continuously or intermittently inject physiological saline into the fragmentation area. This serves two purposes: flushing away debris and maintaining a clear field of vision, and lowering the local temperature to prevent thermal damage. Simultaneously, the external negative pressure suction device is activated, continuously aspirating the fragmented tissue residue, flushing fluid, and blood mixture from the body through the suction connector 53 and the lumen of the inner sheath 51. Throughout the fragmentation process, the camera 34 provides real-time images, allowing the operator to judge the fragmentation boundaries and avoid damaging normal tissue outside the tumor capsule. After fragmentation is complete, the second motor switch 15 is turned off, and the inner sheath 51 and the fragmentation stirring head 52 are retracted into the receiving cavity of the functional head 3 via the "retract" direction of the second control component 17.

[0047] Through the orderly coordination of the above components, this system realizes a closed-loop treatment process of "visual guidance, pre-coagulation hemostasis and inactivation, mechanical disintegration, and synchronous flushing and suction", which significantly reduces surgical risks and operational difficulties.

[0048] The above description of the present invention is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
