Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a press-type laparoscopic irrigation device. Background Technology

[0002] In laparoscopic surgery, negative pressure suction devices are essential equipment used to remove blood, fluid, and smoke from the surgical field to maintain a clear view. Existing medical negative pressure suction devices typically consist of a movable support cart, two waste fluid collection bottles of different sizes mounted on the cart, connecting tubing, and an overflow protection assembly. During use, one end of the suction tube is connected to the waste fluid bottle, while the other end is held by the surgical assistant or surgeon and inserted into the surgical area. Negative pressure generated by an electric negative pressure pump draws in the waste fluid and temporarily stores it in the bottle. Meanwhile, modern standard operating rooms are equipped with centralized negative pressure terminal interfaces and compressed air terminal interfaces. These two air sources are stable and clean. However, in routine surgeries, the negative pressure terminal only provides negative pressure to the cart-type suction device via a long tube, while the compressed air terminal is mostly idle and only used occasionally when pneumatic tools are needed.

[0003] However, in actual laparoscopic surgery, the laparoscope lens often becomes contaminated with blood, tissue fluid, or aerosols, resulting in blurred vision. In such cases, the standard procedure is for the surgeon to remove the laparoscope, and a scrub nurse to use a separate irrigation ball, syringe, or pre-filled pressure bag with irrigation fluid to clean the lens tip offline before reinserting it into the abdominal cavity. This process is cumbersome and time-consuming, disrupting the continuity and rhythm of the surgery. Especially during critical moments of the surgery, frequent instrument switching not only increases the unnecessary workload of medical staff but also indirectly prolongs the patient's anesthesia time. Summary of the Invention

[0004] The purpose of this invention is to provide a press-type laparoscopic irrigation device to solve the problem that the existing negative pressure suction device has a single function and cannot utilize the centralized air supply resources of the operating room to achieve integrated and instantaneous switching between suction and irrigation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a press-type laparoscopic irrigation device, including a movable base;

A positioning rod is movably connected to the back plate of the positioning frame, and the positioning rod passes through the back plate of the positioning frame and cooperates with the positioning holes.

[0020] Furthermore, the left and right side walls of the positioning frame are equipped with docking plates, and the top of the docking plates is formed with a mating groove. The cross-section of the mating groove is T-shaped, and the vertical section of the T-shape extends outward through the side plate of the positioning frame. The mating groove is provided with a movably connected mating component, and the first waste liquid collection bottle and the second waste liquid collection bottle are respectively fixedly installed on the mating component.

[0021] Furthermore, it also includes a negative pressure safety bottle, the body of which is provided with a support plate, the support plate being detachably mounted on the front end face of the positioning frame by means of a locking device;

[0022] The top of the negative pressure safety bottle is equipped with a regulating valve and a pressure gauge. One end of the negative pressure supply pipeline is connected to the inlet end of the regulating valve, and the inlet end of the first pipeline is connected to the outlet end of the regulating valve. The regulating valve is also equipped with a pair of regulating knobs for pressure control.

[0023] Furthermore, the inlet ends of the negative pressure supply pipeline and the positive pressure supply pipeline are respectively equipped with quick-connect couplings, which are compatible with the negative pressure terminal and compressed air terminal on the hospital's central air supply system equipment.

[0024] Furthermore, the positive and negative pressure conversion assembly consists of a housing, a rotating disk, a flow guide channel, a positioning column, and a limiting plate. The housing is columnar and its bottom is fixedly installed in the receiving groove. The interior of the housing is provided with a placement groove. One end of the suction pipe, the flushing pipe, the second pipe, and the third pipe are respectively fixedly installed on the housing, and their end faces are flush with the groove wall of the placement groove.

[0025] Furthermore, the flow guiding channel extends laterally through the rotating disk, serving to connect the suction pipe to the second pipe, or the flushing pipe to the third pipe. The positioning post is fixedly connected to the bottom of the rotating disk, and the top of the positioning post is movably inserted into the bottom plate of the housing. The limiting plate is fixedly connected in a ring shape to the positioning post and below the rotating disk. There are four limiting plates, which are respectively located directly below the suction pipe, flushing pipe, second pipe, and third pipe.

[0027] Furthermore, the handheld operating component consists of an operating lever and a pressure spring. The vertical section of the operating lever is T-shaped. The bottom of the T-shaped vertical section of the operating lever passes through the top plate of the housing and is fixedly connected to the top of the rotating disk. The pressure spring is sleeved on the T-shaped vertical section of the operating lever.

[0028] The top of the housing is provided with two marking lines, which are respectively arranged along the axis of the suction pipe and the flushing pipe. A pointer is provided on the outer wall of the T-shaped transverse section of the operating rod to indicate the direction in which the flow guide channel is aligned with the suction pipe or the flushing pipe.

[0029] Compared with the prior art, the present invention provides a press-type laparoscopic irrigation device, which, by setting up a positive and negative pressure conversion component, a suction tube, an irrigation tube, a second tube, and a third tube, and by setting the suction tube and the second tube to correspond to each other and the irrigation tube and the third tube to correspond to each other, allows the hand-held operating piece to be rotated to switch between suction mode and irrigation mode. It integrates both suction and irrigation functions on the same device, eliminating the need for medical staff to temporarily change or assemble separate irrigation instruments during surgery, which helps to reduce operation interruption time and maintain the continuity of the surgical rhythm.

[0030] Meanwhile, by setting up a negative pressure supply pipeline for connecting to an external negative pressure source and a positive pressure supply pipeline for connecting to an external positive pressure source, the device can directly utilize the existing centralized air supply resources of the operating room equipment to drive suction and flushing operations. There is no need to configure additional active power components such as electric pumps on the trolley or base, which helps to reduce equipment operating noise and manufacturing costs, and also reduces the number of cables and equipment around the operating table, freeing up more space for surgical operations.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] As attached Figure 1 To be continued Figure 8 As shown:

[0044] Example 1:

[0045] This embodiment provides a press-type laparoscopic irrigation device, including a movable base 1, a positioning frame 2, a support and adjustment assembly, a first waste fluid collection bottle 3, a second waste fluid collection bottle 4, a negative pressure supply line 6, a positive pressure supply line 8, a support frame 10, a positive and negative pressure conversion assembly, a suction line 12, an irrigation line 13, a second line 14, a third line 15, and a handheld operating component 16.

[0046] A movable base 1 is located at the bottom of the entire device, used to support and move the irrigation device. A positioning frame 2 is located above the movable base 1; the positioning frame 2 is a frame structure used to install and support other components. A support adjustment assembly is located between the movable base 1 and the positioning frame 2. The bottom of the support adjustment assembly is installed at the top center of the movable base 1, and the top of the support adjustment assembly is connected to the interior of the positioning frame 2. By operating the support adjustment assembly, the height of the positioning frame 2 relative to the movable base 1 can be adjusted to accommodate different operating table heights or the operating habits of medical personnel.

[0047] The first waste fluid collection bottle 3 and the second waste fluid collection bottle 4 are detachably installed on the left and right sides of the positioning frame 2, respectively, for easy removal for cleaning and disinfection after surgery. A series pipe 5 is installed between the tops of the first waste fluid collection bottle 3 and the second waste fluid collection bottle 4. The function of the series pipe 5 is that when the waste fluid in the first waste fluid collection bottle 3 reaches a certain volume, excess waste fluid can overflow through the series pipe 5 into the second waste fluid collection bottle 4 for continued collection, thereby extending the continuous use time per cycle.

[0048] The negative pressure supply pipeline 6 is located in front of the positioning frame 2. One end of it is used to connect to an external negative pressure source, such as the negative pressure terminal on the equipment belt of the hospital's central gas supply system, and the other end is connected to the negative pressure interface on the upper part of the first waste liquid collection bottle 3 through the first pipeline 7. When the external negative pressure source is turned on, the negative pressure is transmitted to the inside of the first waste liquid collection bottle 3 through the negative pressure supply pipeline 6 and the first pipeline 7, and further transmitted to the inside of the second waste liquid collection bottle 4 through the series pipe 5, so that both waste liquid collection bottles are in a negative pressure state.

[0049] The positive pressure supply line 8 is located behind the positioning frame 2. One end of it is connected to an external positive pressure gas source, such as a compressed air terminal on a hospital central gas supply system, and the other end is connected to the bottom of the irrigation fluid bag 9. The irrigation fluid bag 9 is suspended from the positioning frame 2 or the support frame 10 and contains physiological saline or other irrigation fluid for intraoperative irrigation. When external positive pressure gas enters the bottom of the irrigation fluid bag 9 through the positive pressure supply line 8, the positive pressure acts above the liquid surface, providing driving force for the irrigation fluid to flow out.

[0050] The support frame 10 is positioned on top of the positioning frame 2, and a receiving groove 11 is formed on the top of the support frame 10. The receiving groove 11 is used to accommodate and fix the positive and negative pressure conversion component. The positive and negative pressure conversion component is set in the receiving groove 11 and serves as the core component for switching between the suction and rinsing functions of the entire device.

[0051] Suction tubing 12 and irrigation tubing 13 are respectively connected to the positive and negative pressure conversion assembly. One end of suction tubing 12 is fixed to the positive and negative pressure conversion assembly, and the other end extends to the surgical area for suctioning waste fluid during surgery. One end of irrigation tubing 13 is also fixed to the positive and negative pressure conversion assembly, and the other end also extends to the surgical area for spraying irrigation fluid during surgery.

[0052] The second pipe 14 connects the second waste liquid collection bottle 4 and the positive / negative pressure conversion assembly. One end of the second pipe 14 is connected to the interface at the top of the second waste liquid collection bottle 4, and the other end is fixed to the positive / negative pressure conversion assembly. The third pipe 15 connects the flushing fluid bag 9 and the positive / negative pressure conversion assembly. One end of the third pipe 15 is connected to the outlet of the flushing fluid bag 9, and the other end is fixed to the positive / negative pressure conversion assembly.

[0053] On the positive and negative pressure conversion assembly, the inlets of the suction pipe 12 and the second pipe 14 are positioned opposite each other, and the third pipe 15 and the flushing pipe 13 are positioned opposite each other. A handheld operating component 16 is rotatably connected to the positive and negative pressure conversion assembly. By rotating the handheld operating component 16, the switching of the internal flow channels of the positive and negative pressure conversion assembly can be controlled, thereby controlling the flushing fluid to be sent out from the flushing pipe 13, or controlling the suction pipe 12 to generate negative pressure for waste liquid suction.

[0054] The working principle of this embodiment is as follows: When the suction function is needed, the medical staff rotates the handheld operating device 16 to connect the suction tube 12 and the second tube 14 in the positive and negative pressure conversion component. At this time, the negative pressure is transmitted from the first waste liquid collection bottle 3 and the second waste liquid collection bottle 4 to the suction tube 12 through the second tube 14. The front end of the suction tube 12 generates negative pressure, which can suck the blood, effusion, etc. in the surgical field into the waste liquid collection bottle. When the flushing function is needed, the handheld operating device 16 is rotated to connect the third tube 15 and the flushing tube 13 in the positive and negative pressure conversion component. The positive pressure gas is pressed into the bottom of the flushing fluid bag 9 through the positive pressure supply tube 8. The flushing fluid is sent out through the third tube 15 and the flushing tube 13 under the positive pressure drive to flush the surgical area.

[0055] Example 2:

[0056] Based on Embodiment 1, this embodiment further defines the installation structure of the support adjustment component and the waste liquid collection bottle.

[0057] The support adjustment assembly consists of a support column 17, an adjusting rod 18, and auxiliary bearings 19. The support column 17 is a vertically oriented column structure, its bottom mounted on the top center of the movable base 1 via bolts or other detachable means. A threaded groove is formed axially downwards at the top center of the support column 17, and the inner wall of the threaded groove has internal threads. The adjusting rod 18 is a vertically oriented rod structure with a threaded section 1801 on its body. The outer wall of the threaded section 1801 has external threads that mate with the threaded groove, and the threaded section 1801 and the threaded groove are threadedly engaged. There are two auxiliary bearings 19, symmetrically arranged on the adjusting rod 18 and located above the threaded section 1801. The inner ring of each auxiliary bearing 19 is fixedly fitted onto the adjusting rod 18, and the outer ring of each auxiliary bearing 19 is fixed inside the positioning frame 2. When the adjusting rod 18 is rotated, the adjusting rod 18 moves up and down relative to the support column 17 along the axial direction through the threaded engagement of the threaded part 1801 and the threaded groove, and drives the positioning frame 2 to rise and fall synchronously through the auxiliary bearing 19, thereby realizing stepless adjustment of the height of the positioning frame 2.

[0058] Furthermore, the side wall of the support column 17 is provided with horizontally distributed positioning holes 20. The positioning holes 20 are arranged in a ring around the circumference of the support column 17, and their axial position is located between the two auxiliary bearings 19. A positioning rod 21 is movably connected to the back plate of the positioning frame 2. The positioning rod 21 can move back and forth in the horizontal direction. The front end of the positioning rod 21 passes through the back plate of the positioning frame 2 and can be inserted into the positioning hole 20. When the height of the positioning frame 2 is adjusted to a suitable position, the positioning rod 21 is pushed into the corresponding positioning hole 20, which can lock the circumferential position of the positioning frame 2, prevent the positioning frame 2 from rotating accidentally during use, and improve the stability of the device.

[0059] For the installation of the waste liquid collection bottle, a docking plate 22 is installed on each of the left and right side walls of the positioning frame 2. The top of the docking plate 22 forms a mating groove 23 facing downwards. The mating groove 23 has a T-shaped cross-section, with the vertical section of the T-shape extending outwards through the side plate of the positioning frame 2; that is, the opening of the mating groove 23 faces the outside of the positioning frame 2. A mating component 24, which can be vertically inserted and removed, is provided within the mating groove 23. The cross-sectional shape of the mating component 24 matches the T-shaped cross-section of the mating groove 23. The first waste liquid collection bottle 3 and the second waste liquid collection bottle 4 are respectively fixedly installed on the mating component 24 on the corresponding side using clamps or other fasteners. When it is necessary to disassemble the waste liquid collection bottle, simply remove the mating component 24 along with the waste liquid collection bottle from the mating groove 23 upwards; the operation is convenient and quick.

[0060] Example 3:

[0061] Based on the above embodiments, this embodiment adds a negative pressure safety bottle 25 and optimizes the interface form of the negative pressure supply pipeline 6 and the positive pressure supply pipeline 8.

[0062] A support plate 26 is fixedly mounted on the body of the negative pressure safety bottle 25. The support plate 26 is detachably mounted on the front end face of the positioning frame 2 via a locking device. The negative pressure safety bottle 25 is connected to the gas line between the negative pressure supply line 6 and the waste liquid collection bottle to prevent liquid in the waste liquid collection bottle from being drawn back into the negative pressure supply line 6 or even an external negative pressure source. The top of the negative pressure safety bottle 25 is equipped with a regulating valve 27 and a pressure gauge 28. One end of the negative pressure supply line 6 is connected to the inlet end of the regulating valve 27, and the inlet end of the first line 7 is connected to the outlet end of the regulating valve 27. The regulating valve 27 is also equipped with a pair of pressure control knobs 29. By turning the regulating knobs 29, the gas flow rate or pressure through the regulating valve 27 can be adjusted. The pressure gauge 28 displays the current pressure value in the negative pressure line in real time, which allows medical staff to accurately control the amount of suction negative pressure according to the needs of the operation.

[0063] The inlet ends of the negative pressure supply line 6 and the positive pressure supply line 8 are respectively equipped with quick-connect couplings, which are compatible with the negative pressure terminal and compressed air terminal on the hospital's central air supply system equipment. By using the quick-connect couplings, the air source connection can be completed simply by inserting the end of the line into the corresponding terminal interface, and the connection can be disconnected by pulling it out. The operation is simple and the airtightness is good.

[0064] The remaining structure and working principle of this embodiment are the same as those of Embodiment 1 or Embodiment 2, and will not be repeated here.

[0065] Example 4:

[0066] Based on the above embodiments, this embodiment provides a detailed definition of the specific structure of the positive and negative pressure conversion component.

[0067] The positive and negative pressure conversion assembly consists of a housing 30, a rotating disk 31, a flow guide channel 32, a positioning post 33, and a limiting plate 34. The housing 30 is cylindrical, and its bottom is fixedly installed in the receiving groove 11 of the supporting frame 10 by screws or adhesive. A cylindrical placement groove 35 is opened inside the housing 30. One end of the suction pipe 12, flushing pipe 13, second pipe 14, and third pipe 15 are respectively fixedly installed on the side wall of the housing 30. The end face of the four pipes inside the housing 30 is flush with the groove wall of the placement groove 35, so that when the rotating disk 31 rotates in the placement groove 35, its outer ring wall can be in contact with or separate from the end face of each pipe, realizing the on / off control of the air passage.

[0068] The rotating disk 31 is cylindrical, with its outer diameter slightly smaller than the inner diameter of the placement groove 35. The flow guide channel 32 extends transversely through the rotating disk 31, meaning it is a straight channel running through the diameter of the rotating disk 31. The two openings of the flow guide channel 32 correspond to two positions on the outer ring wall of the rotating disk 31. When the rotating disk 31 rotates to a certain angle, the flow guide channel 32 can connect the suction pipe 12 to the second pipe 14, or connect the flushing pipe 13 to the third pipe 15, thereby achieving pipe switching.

[0069] Furthermore, a rubber sealing ring is fitted onto the outer ring wall of the rotating disk 31. The outer wall of the rubber sealing ring is in close contact with the groove wall of the placement groove 35 to enhance the airtightness between the rotating disk 31 and the housing 30. The height of the rotating disk 31 is less than the groove height of the placement groove 35, allowing the rotating disk 31 to have a certain amount of vertical movement space within the placement groove 35, which facilitates pressing operations.

[0070] The positioning post 33 is fixedly connected to the bottom center of the rotating disk 31. The top of the positioning post 33 is movably inserted into the central hole opened in the bottom plate of the housing 30. The positioning post 33 can slide vertically and rotate around its own axis within the central hole. The limiting plates 34 are arranged in a ring and fixedly connected to the outer wall of the positioning post 33, located below the rotating disk 31. There are four limiting plates 34, which are located directly below the suction pipe 12, the flushing pipe 13, the second pipe 14, and the third pipe 15, respectively. The bottom of the limiting plates 34 is movably inserted into the corresponding arc-shaped limiting groove opened in the bottom plate of the housing 30. The bottom height of the positioning post 33 is lower than the bottom height of the limiting plates 34, so that the bottom end of the positioning post 33 contacts the bottom plate of the housing 30 before the limiting plates 34, thus playing a positioning and guiding role.

[0071] The handheld operating component 16 consists of an operating lever 1601 and a pressure spring 1602. The vertical section of the operating lever 1601 is T-shaped, and the bottom of the T-shaped vertical section of the operating lever 1601 passes through the central hole of the top plate of the housing 30 and is fixedly connected to the top center of the rotating disk 31. The pressure spring 1602 is sleeved on the T-shaped vertical section of the operating lever 1601. The upper end of the pressure spring 1602 abuts against the inner wall of the top plate of the housing 30, and the lower end abuts against the top surface of the rotating disk 31 or other limiting steps, providing a downward restoring force for the operating lever 1601.

[0072] Two marking lines 36 are provided on the top of the housing 30, respectively, along the axial direction of the suction pipe 12 and the flushing pipe 13, to indicate the current orientation of the internal flow channel 32 of the rotating disk 31. A pointer 37 is provided on the outer wall of the T-shaped transverse section of the operating lever 1601, and the orientation of the pointer 37 is consistent with the orientation of the flow channel 32. When the hand-held operating lever 1601 is rotated, the pointer 37 rotates accordingly. By observing which marking line 36 the pointer 37 points to, it can be intuitively determined whether the flow channel 32 is currently aligned with the suction pipe 12 or the flushing pipe 13.

[0073] The operation method of this embodiment is as follows: Medical staff lift the operating lever 1601 upwards. The operating lever 1601 drives the rotating disk 31 and the positioning post 33 to move upwards against the elastic force of the downward spring 1602. The bottom of the limiting plate 34 disengages from the arc-shaped limiting groove, and the rotating disk 31 is in a state of free rotation. Rotate the operating lever 1601 so that the pointer 37 is aligned with the mark line 36 of the desired function. For example, when aligned with the mark line 36 in the direction of the suction tube 12, the guide channel 32 connects the suction tube 12 and the second tube 14. Then release the operating lever 1601. Under the restoring force of the downward spring 1602, the rotating disk 31 moves downwards, and the bottom of the limiting plate 34 re-inserts into the corresponding arc-shaped limiting groove, locking the circumferential position of the rotating disk 31 to prevent accidental rotation during use. Similarly, when flushing is required, repeat the above operation and turn the pointer 37 to the direction of the flushing tube 13.

[0074] The remaining structure and working principle of this embodiment are the same as those of the previous embodiments, and will not be repeated here.

[0075] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
