Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multifunctional thoracic and abdominal cavity irrigation and suction device. Background Technology

[0002] With the development of medical technology, thoracic and abdominal surgery has become an important part of clinical surgery. During thoracic and abdominal surgery, in order to maintain a clear surgical field and clean the surgical site, it is usually necessary to use irrigation and suction devices to irrigate and suction the surgical site.

[0003] Existing thoracic and abdominal cavity irrigation and aspiration devices have the following problems: First, during thoracic and abdominal surgeries, blood clots and adhesions often appear at the surgical site, especially in concealed areas. These residues are difficult to completely remove by aspiration alone. Existing irrigation devices have insufficient irrigation power and cannot effectively remove these residues, which may lead to postoperative complications.

[0004] Secondly, during the procedure, patients are usually in a supine or lateral position. Due to gravity, the rinsing fluid from existing rinsing devices tends to accumulate in the lower area, while the upper area (the anti-gravity area) is difficult to rinse effectively, resulting in uneven cleaning.

[0005] Third, existing irrigation devices generally use room temperature irrigation fluid, which can adversely affect the patient's perioperative recovery. Studies have shown that the surgical procedure itself causes trauma to the patient, and factors such as anesthesia and intraoperative fluid infusion may lead to hypothermia. Especially in abdominal surgery, patients are prone to hypothermia and reduced vasomotor function, which is often accompanied by local tissue ischemia and hypoxia, leading to a series of complications such as poor wound healing, increased risk of infection, increased oxygen consumption, exacerbated shivering, and impaired coagulation function. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional thoracic and abdominal cavity irrigation and suction device that can effectively remove surgical site residues, achieve all-round irrigation, and maintain a constant temperature of the irrigation fluid.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A multifunctional thoracic and abdominal cavity irrigation and suction device includes a handle operation assembly, the lower end of which is provided with a power input port, a water inlet and a water outlet;

[0009] A flushing and suction assembly is detachably connected to the handle operation assembly. The flushing and suction assembly includes a tube with a hollow cavity and an ablation electrode disposed within the tube.

[0010] A water outlet mode knob assembly is provided at the water outlet end of the flushing suction assembly; the water inlet is connected to a miniature electric heater for heating the flushing fluid entering the tube.

[0011] Furthermore, the flushing and suction assembly further includes a pull button, which contains a pressure spring. The pull button is connected to the tube body and is used to retract the ablation electrode into the tube body when not in operation. The pull button is rotatable 360 ​​degrees along the axis of the tube body.

[0012] Furthermore, the water outlet mode knob assembly includes an inner ring and an outer ring. The relative rotation of the inner ring and the outer ring is used to adjust the water outlet mode of the water outlet end of the flushing suction assembly. The water outlet mode includes a normal water outlet mode, a mist water outlet mode, and a jet water outlet mode.

[0013] Furthermore: the outer ring component has a regular water outlet, a mist water outlet, and a jet water outlet, and the inner ring component has multiple regular water outlets; the inner ring component and the outer ring component are connected by an I-shaped shift groove, and by rotating the relative angle and position of the inner ring component and the outer ring component along the I-shaped shift groove, the regular water outlet, mist water outlet, and jet water outlet on the outer ring component are respectively matched with the positions of the multiple regular water outlets on the inner ring component.

[0014] Furthermore: the inner ring component is provided with a one-way valve sealing component at one end in the water outlet direction, and the opening direction of the one-way valve sealing component is opposite to the water outlet direction; the outer ring component is provided with an annular protrusion at the end face in the water outlet direction, and the annular protrusion faces the one-way valve sealing component.

[0015] Furthermore, the handle operation assembly also includes a miniature booster water pump, which is connected to the water inlet and used to adjust the outlet pressure of the flushing liquid; the outside of the handle operation assembly is provided with an adjustment knob, which is connected to the miniature booster water pump and used to adjust the output pressure of the miniature booster water pump.

[0016] Furthermore, it also includes a temperature-controlled booster box, which includes the micro booster water pump and the micro electric heater. The temperature-controlled booster box is connected to the water inlet and is installed inside or outside the handle operation assembly.

[0017] Furthermore, the miniature electric heater is used to heat the rinsing fluid to 36.5±0.5℃.

[0018] Furthermore, the outer side of the handle operating component is also provided with: a water inlet opening button for controlling the opening and closing of the water inlet; a water outlet opening button for controlling the opening and closing of the water outlet; and a component assembly / disassembly button for controlling the assembly and disassembly of the flushing suction component and the handle operating component.

[0019] Furthermore, the handle operation component also includes a safety pull ring, which is used to lock the water inlet open button and the water outlet open button in the closed state.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] I. This invention, by setting a miniature electric heater in the handle operating component, can heat the irrigation fluid and maintain it at a constant temperature of 36.5±0.5℃, avoiding the adverse effects of intraoperative tissue spasm and vasoconstriction caused by room temperature irrigation fluid, which is beneficial to the patient's postoperative recovery.

[0022] II. The water outlet mode knob assembly of this invention, through the relative rotational engagement of the inner and outer ring components, can achieve three water outlet modes: normal water outlet, mist water outlet, and jet water outlet. The enhanced water flow generated by the jet water outlet mode can effectively remove residual blood clots in hidden areas, avoiding postoperative complications. The mist water outlet mode can be used to uniformly rinse the anterior thoracic and abdominal wall tissues within the thoracic and abdominal cavities, effectively infiltrating metastatic tumor cells and dissolving them in the irrigation fluid, overcoming the problem of dead zones in rinsing caused by gravity in existing devices. Furthermore, the inclusion of a micro-boosting water pump further ensures the rinsing effect under different water outlet modes.

[0023] Third, the flushing and suction assembly of the present invention adopts a pull button with built-in pressure spring structure design to ensure that the ablation electrode automatically retracts into the tube when not in use, and with the protection mechanism of the safety pull ring, it effectively prevents tissue damage caused by misoperation and improves surgical safety.

[0024] Fourth, the pull button can rotate 360 ​​degrees along the axis of the tube body, and with different water outlet modes, it can achieve effective flushing of the thoracic and abdominal cavities from all directions without dead angles. Attached Figure Description

Detailed Implementation

[0039] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] The multifunctional thoracic and abdominal cavity irrigation and suction device provided by this invention includes a handle operation assembly 1, an irrigation and suction assembly, and a water outlet mode knob assembly 15. The lower end of the handle operation assembly 1 is provided with a power input port 2, a water inlet 3, and a water outlet 4. The irrigation and suction assembly is detachably connected to the handle operation assembly 1. The water outlet mode knob assembly 15 is located at the water outlet end of the irrigation and suction assembly. A miniature electric heater 5 is provided inside the handle operation assembly 1 for heating the irrigation fluid flowing through it.

[0042] The upper outer part of the handle operating assembly 1 is equipped with multiple function switches or buttons and a safety pull ring 7. These function switches or buttons include a water inlet opening button 8, a water outlet opening button 9, an assembly installation / removal button, and an on / off switch for starting the micro booster water pump 6 and the micro electric heater 5. An adjustment knob 10 for adjusting the water outlet pressure is also located at the top of the handle. One end of the external power cord is connected to the power input port 2 of the handle operating assembly 1, and the other end can be connected to the standard output interface of relevant ablation equipment in the operating room.

[0043] The flushing and suction assembly includes a hollow tube 12 and an ablation electrode 13 disposed within the tube 12. The assembly also includes a pull button 11, which contains a pressure spring 14. The pull button 11 is connected to the tube 12 and automatically retracts the ablation electrode 13 into the tube 12 when not in use, thus preventing tissue damage caused by accidental operation. Furthermore, a safety pull ring 7 on the handle operating assembly 1 provides an additional safety protection mechanism for locking the inlet / outlet opening button 8 and the outlet / outlet opening button 9 in the closed position.

[0044] The water outlet mode knob assembly 15 includes an inner ring 15.2 and an outer ring 15.1. The outer ring 15.1 has a regular water outlet 15.11, a mist water outlet 15.13, and a jet water outlet 15.12, while the inner ring 15.2 has multiple regular water outlets 15.11. The inner ring 15.2 and the outer ring 15.1 are connected by an I-shaped shift groove 15.3. One-way valve sealing element 15.4 is provided at one end of the inner ring 15.2 in the water outlet direction, and the opening direction of the one-way valve sealing element 15.4 is opposite to the water outlet direction. An annular protrusion 15.5 is provided on the water outlet direction end face of the outer ring 15.1, and the annular protrusion 15.5 faces the one-way valve sealing element 15.4. By rotating the inner ring 15.2 and outer ring 15.1 along the I-shaped shift groove 15.3, the relative angle and position of the two can be changed, so that the different types of cleaning water outlets on the outer ring 15.1 can be matched with the ordinary water outlet 15.11 on the inner ring 15.2, thereby realizing three different water outlet modes: ordinary water outlet mode, mist water outlet mode, and jet water outlet mode.

[0045] The miniature booster pump 6, located within the handle operating assembly 1, is used to adjust the outlet pressure of the irrigation fluid. Users can adjust the output pressure of the miniature booster pump 6 via the adjustment knob 10 on the outside of the handle, thus adapting to different water flow patterns and irrigation needs of different surgical sites. Specifically, the jet water flow pattern is primarily used to remove difficult-to-clean debris such as residual blood clots from hidden areas; the mist water flow pattern is used for uniform irrigation of organs within the thoracic and abdominal cavities, and is particularly suitable for delicate procedures such as cancer cell sampling.

[0046] The miniature electric heater 5 can heat the irrigation fluid to a constant temperature of 36.5±0.5℃. This temperature setting is close to the normal human body temperature, which can avoid tissue spasms caused by cold irrigation fluid, reduce the impact on the surgical field, and help maintain the patient's body temperature stability, thus improving the surgical prognosis.

[0047] In use, the external power cord is first connected to the ablation device in the operating room, and the miniature booster water pump 6 and miniature electric heater 5 on the handle operating assembly 1 are started. Water inlet is controlled by the water inlet opening button 8, and the irrigation fluid is heated to the preset temperature by the miniature electric heater 5. Depending on the surgical needs, the appropriate water outlet mode is selected by rotating the water outlet mode knob assembly 15, and the water pressure is adjusted by adjusting the knob 10. When the ablation electrode 13 needs to be used, the pull button 11 is pulled to extend the ablation electrode 13 out of the tube body 12. After releasing the pull button 11, the ablation electrode 13 automatically retracts into the tube body 12 under the action of the pressure spring 14. The end of the ablation electrode 13 can be a right-angle hook, a rounded hook, a blade shape, etc. During the operation, the irrigation and suction assembly can be removed from the handle operating assembly 1 for replacement by pressing the assembly removal button as needed.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent transformations or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
