Description

Technical Field

[0001] This invention relates to the field of laser processing, and more particularly to a single-hole multi-channel surgical device with an adjustable circulating air intake and exhaust system. Background Technology

[0002] Minimally invasive laparoscopic surgery is a significant trend in modern surgery. It involves inserting surgical instruments and imaging systems through tiny incisions in the body surface, offering significant advantages such as minimal trauma and rapid recovery. Single-port multi-channel surgical devices, as key instruments in laparoscopic surgery, integrate multiple instrument channels onto a single platform, entering the abdominal cavity through natural cavities such as the umbilicus or a single small incision. This achieves better aesthetic results while further minimizing surgical trauma. Maintaining a clear and stable surgical field is crucial in this procedure, relying on a continuous and clean pneumoperitoneum environment. However, the use of energy instruments such as high-frequency electrosurgical units during surgery generates a large amount of smoke. This smoke is difficult to dissipate within the closed abdominal cavity, directly interfering with the endoscopic view and becoming a core challenge affecting surgical safety and efficiency.

[0003] In existing technologies, traditional single-port multi-channel surgical devices typically have basic air intake and exhaust functions, and the position and direction of their air intake and smoke exhaust ports are often fixed. During surgery, when smoke is generated and accumulates at specific locations in the abdominal cavity (such as the surgical manipulation point), the fixed suction port cannot directly and effectively target the smoke source. This results in low smoke removal efficiency, prolonged smoke retention time within the cavity, and severe obstruction of vision, forcing surgeons to frequently pause operations to wait for the smoke to dissipate. This not only prolongs the surgical time but also increases the risk of accidental damage to surrounding tissues due to poor visibility.

[0004] Therefore, how to achieve real-time and precise removal of smoke during surgery is a problem that needs to be solved by existing single-port laparoscopic techniques. Summary of the Invention

[0005] The purpose of this invention is to provide a single-hole multi-channel surgical device with an adjustable circulating air intake and smoke exhaust system, thereby solving the above-mentioned technical problems.

[0006] To achieve this objective, the present invention adopts the following technical solution: A single-port multi-channel surgical device with an adjustable circulating air intake and smoke exhaust system includes: Instrument platform; Several instrument channels are provided on the instrument platform to provide channels for surgical instruments to enter the surgical cavity; An air intake and exhaust port is located near the end of the instrument platform and is used to connect an external pneumoperitoneum machine and a gas filtration device. An air intake and smoke exhaust channel, one end of which is connected to the air intake and smoke exhaust interface; An internal air intake and smoke exhaust port is located at the far end of the instrument platform and connected to the other end of the air intake and smoke exhaust channel, for extending into the surgical cavity for gas exchange. A fixed adjustment component is provided, wherein the air intake and smoke exhaust channel is adjustablely mounted on the fixed adjustment component. By operating the fixed adjustment component, the angle, direction, and position of the air intake and smoke exhaust channel and the built-in air intake and smoke exhaust port within the surgical cavity can be adjusted and fixed. A real-time pressure measurement interface is provided on the instrument platform for connecting an external pressure monitoring device and extending the pressure measurement end into the surgical cavity; And an incision protective sleeve, located at the distal end of the instrument platform.

[0007] Optionally, the instrument platform is provided with a support block, which is disposed between a plurality of the instrument channels and the fixing and adjusting assembly; The support block includes a body that can be detachably installed on the instrument platform. The outer periphery of the body has multiple notches that abut against the outer wall of the instrument channel to provide support for the instrument channel.

[0008] Optionally, the air intake and exhaust interface includes a first chamber for supplying air intake, a second chamber for supplying exhaust, and a third chamber for connecting to the aforementioned real-time pressure measurement interface; wherein adjacent chambers are separated by a partition assembly.

[0009] Optionally, the partition assembly includes a first partition and a second partition, with one end of the second partition vertically disposed in the middle of the first partition; wherein the first partition is a straight plate or a curved plate.

[0010] Optionally, the partition assembly includes a plurality of concentrically arranged annular partitions, with a chamber formed between two adjacent annular partitions.

[0011] Optionally, the fixing and adjusting assembly is disposed on the top or side of the instrument platform, and the fixing and adjusting assembly includes an outer shell mounted on the instrument platform and an adjusting knob disposed on the outer shell; The outer casing has an inner cavity for the air intake and exhaust channel to pass through, and the air intake and exhaust channel is connected to the adjustment knob; The inner cavity has a first threaded portion on its side wall, and the outer side wall of the adjustment knob is threaded to the first threaded portion; wherein, one end of the adjustment knob is provided with a scale portion.

[0012] Optionally, a sealing ring is provided between the outer casing and the adjustment knob, the sealing ring being used to seal the air intake and exhaust channels; One end of the outer casing is provided with a mounting groove and a plug-in part in sequence, and the diameter of the plug-in part gradually decreases along the plugging direction of the fixing and adjusting component; The instrument platform has a pre-set insertion slot, and the side wall of the insertion slot has a protrusion. When the fixing and adjusting component is inserted into the insertion slot, the protrusion is engaged in the mounting slot.

[0013] Optionally, a plurality of first air holes are provided on the side wall of the built-in air intake and exhaust port, and a plurality of second air holes are provided at the end of the built-in air intake and exhaust port. The first vent is connected to the first chamber, and the second vent is connected to the second chamber.

[0014] Optionally, the air intake and exhaust interface can be integrated with the real-time pressure measurement interface, or it can be set separately as an independent interface on the instrument platform.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When using this surgical device, it is first inserted into and fixed to the patient's incision through its distal incision protective sleeve. Before surgery, the air intake and exhaust port at the proximal end of the instrument platform is connected to an external intelligent pneumoperitoneum machine and filtration device, and the real-time pressure measurement interface is connected to a pressure monitoring device. During surgery, the gas generated by the pneumoperitoneum machine passes through the air intake and exhaust port and the air intake and exhaust channel, and is finally output through the built-in air intake and exhaust port extending into the surgical cavity to establish and maintain pneumoperitoneum. Surgical instruments enter the cavity through several instrument channels for operation. When electrocautery, electrocoagulation, etc., generate smoke... In the event of fogging, the operator can adjust the fixed adjustment components to change the angle and position of the built-in air intake and smoke exhaust ports within the cavity in real time, aligning them with the smoke-generating area. This allows for efficient reverse suction, filtration, and recycling of the smoke through the original channel. Simultaneously, the real-time pressure monitoring interface continuously monitors the intracavitary pressure and feeds the data back to the pneumoperitoneum machine, achieving closed-loop stable pressure control. Through a single-port device integrating a directional adjustable air intake and smoke exhaust system and real-time pressure monitoring, proactive, precise, and intelligent control of the intracavitary surgical environment, visual clarity, and pressure stability is achieved while ensuring minimally invasive surgery.

Detailed Implementation

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

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and 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, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] This invention provides a single-port multi-channel surgical device with an adjustable circulating air intake and smoke exhaust system, comprising: Instrument platform 10 provides the mounting base for all other functional components (such as instrument channel 20, interface, adjustment components, etc.) and serves as a stable support for external instruments during surgical operations.

[0024] Several instrument channels 20 are set on the instrument platform 10 to provide channels for surgical instruments to enter the surgical cavity; these channels are the main functional channels of the device, allowing multiple surgical instruments such as laparoscopic lenses, grasping forceps, and electrosurgical units to pass through and enter the patient's body cavity (surgical cavity) at the same time, which is the key to completing complex surgical operations with a single incision.

[0025] The air intake and smoke exhaust interface 30 is located at the proximal end of the instrument platform 10 and is used to connect the external insufflator and the gas filtration device. This interface is located at the proximal end of the device near the doctor's operation and serves as a hub for connecting the system with external devices (such as intelligent insufflators and smoke filtration devices). It is responsible for introducing clean gas (such as carbon dioxide) to establish an insufflation and expelling exhaust gas containing smoke.

[0026] The air intake and exhaust channel 40 is connected at one end to the air intake and exhaust interface 30. This is a pipeline (or a group of pipelines) that runs through the inside of the device. As a passage for gas circulation, it connects the air intake and exhaust interface 30 to the air intake and exhaust built-in port 50 that is inserted into the body, so as to realize the directional flow of gas between the external device and the internal surgical cavity.

[0027] An internal air intake and exhaust port 50 is located at the distal end of the instrument platform 10 and connects to the other end of the air intake and exhaust channel 40. It is used to extend into the surgical cavity for gas exchange. This port is located at the distal end of the device that extends into the patient's body and serves as the direct gateway for gas to enter and exit the surgical cavity. Its special design (such as multiple chambers and multiple vents) optimizes gas exchange efficiency, delivers clean gas evenly, and efficiently extracts smoke and mist.

[0028] The fixed adjustment component 60 is on which the air intake and smoke exhaust components are adjustablely mounted. By operating the fixed adjustment component 60, the angle, direction, and position of the air intake and smoke exhaust channel 40 and the built-in air intake and smoke exhaust port 50 within the surgical cavity can be adjusted and fixed. This is the core mechanism for the adjustable function of this device. By movably installing the air intake and smoke exhaust channel 40 or the port portion, the surgeon can adjust the angle and depth position of the port within the cavity in real time and flexibly during the operation according to the needs of the surgery, aligning it with the smoke generation point, thereby significantly improving smoke exhaust efficiency.

[0029] The real-time pressure measurement interface 70 is located on the instrument platform 10 and is used to connect to an external pressure monitoring device and extend the pressure measurement end into the surgical cavity. This is an independent monitoring channel with its sensor end extending into the surgical cavity. It can continuously and directly measure the actual air pressure inside the cavity and feed the data back to the control system, providing a key signal input for achieving accurate, stable and automatic control of pneumoperitoneum pressure.

[0030] And an incision protector 80, located at the distal end of the instrument platform 10. This component is installed at the distal end of the device and comes into direct contact with the patient's incision. Its main functions are to fix the device, open and protect the incision tissue, and ensure a seal between the device and the incision to prevent gas leakage and maintain a stable surgical environment.

[0031] The working principle of this invention is as follows: When using this surgical device, it is first inserted into the patient's incision through the distal incision protective sleeve 80 and fixed. Before the operation, the air intake and smoke exhaust interface 30 at the proximal end of the instrument platform 10 is connected to an external intelligent pneumoperitoneum machine and filtration device, and the real-time pressure measurement interface 70 is connected to a pressure monitoring device. During the operation, the gas generated by the pneumoperitoneum machine passes through the air intake and smoke exhaust interface 30 and the air intake and smoke exhaust channel 40, and is finally output through the built-in air intake and smoke exhaust port 50 that extends into the surgical cavity to establish and maintain pneumoperitoneum. Surgical instruments enter the cavity through several instrument channels 20 for operation. When electrocautery, electrocoagulation, etc., generate smoke... In the event of smoke inhalation, the operator can adjust the fixed adjustment component 60 to change the angle and position of the built-in air intake and smoke exhaust port 50 within the cavity in real time, aligning it with the area where smoke is generated. This allows for efficient reverse suction, filtration, and recycling of the smoke through the original channel. Simultaneously, the real-time pressure monitoring interface 70 continuously monitors the intracavitary pressure and feeds the data back to the pneumoperitoneum machine, achieving closed-loop stable pressure control. Through a single-port device integrating a directional adjustable air intake and smoke exhaust system and real-time pressure monitoring, proactive, precise, and intelligent control of the intracavitary surgical environment, visual clarity, and pressure stability is achieved while ensuring minimally invasive surgery.

[0032] In this embodiment, the instrument platform 10 is provided with a support block 11, which is disposed between a plurality of instrument channels 20 and the fixed adjustment assembly 60. The support block 11 includes a body part 111 that is detachably installed on the instrument platform 10. A plurality of notches 112 are provided on the outer periphery of the body part 111. The notches 112 abut against the outer side wall of the instrument channel 20 to provide support for the instrument channel 20.

[0033] It should be noted that the support block 11 is detachably mounted between the instrument channel 20 on the platform and the fixing and adjusting assembly 60. Multiple notches are provided on its body, which engage and abut against the outer wall of the instrument channel 20. This design aims to provide stable lateral support for the slender instrument channel 20, preventing it from wobbling or deforming during repeated insertion and removal of surgical instruments. Its detachable nature also facilitates cleaning, maintenance, or replacement for different surgical configurations.

[0034] In this embodiment, the air intake and exhaust port 30 includes a first chamber 31 for supplying air intake, a second chamber 32 for supplying exhaust, and a third chamber 33 for connecting to the aforementioned real-time pressure measurement port 70; wherein, adjacent chambers are separated by a partition assembly 34.

[0035] It should be noted that the interface is internally divided into three independent chambers: a first chamber 31 dedicated to the input of clean gas, a second chamber 32 for the discharge of smoke-containing exhaust gas, and a third chamber 33 providing a pathway for real-time pressure measurement signals. These chambers are tightly separated by a partition assembly 34, ensuring that the three critical fluid pathways (gas and signal) for air intake, exhaust, and pressure measurement are independent and do not interfere with each other at the interface. This is the fundamental structure for ensuring reliable system operation.

[0036] As an optional solution in this embodiment, the partition assembly 34 includes a first partition 341 and a second partition 342, with one end of the second partition 342 vertically disposed in the middle of the first partition 341; wherein, the first partition 341 is a straight plate or a curved plate.

[0037] A specific and robust partition implementation is provided. It employs a "T"-shaped or similar cross structure, consisting of a first partition 341 and a second partition 342 vertically connected to its middle. This design effectively utilizes space and forms a stable partition. Notably, the first partition 341 can be a "straight plate" or a "curved plate," providing design flexibility—curved plates can be used to adapt to special interface shapes or optimize internal airflow paths.

[0038] As another optional solution in this embodiment, the partition assembly 34 includes a plurality of concentrically arranged annular partitions, with a chamber formed between two adjacent annular partitions.

[0039] A distinctly different, more compact baffle design is proposed. It employs multiple concentric annular baffles of varying diameters, nested together like sleeves, naturally forming annular chambers between adjacent baffles. This coaxial design allows for a more compact and symmetrical interface structure, potentially facilitating uniform gas flow distribution and interface miniaturization, making it an important alternative for meeting diverse product design requirements.

[0040] In this embodiment, the fixing and adjusting assembly 60 is disposed on the top or side of the instrument platform 10. The fixing and adjusting assembly 60 includes an outer shell 61 installed on the instrument platform 10 and an adjusting knob 62 disposed on the outer shell 61. The outer shell 61 is provided with an inner cavity 611 for the air intake and exhaust channel 40 to pass through. The side wall of the inner cavity 611 is provided with a first threaded portion 612. The outer side wall of the adjusting knob 62 is threaded to the first threaded portion 612. The adjusting knob 62 is provided with a scale portion 621 at one end.

[0041] It should be noted that the fixed adjustment assembly 60 uses an outer housing 61 mounted on a platform as a base, and its internal cavity 611 allows the air intake and smoke exhaust passage 40 to pass through. The key adjustment function is achieved by an adjustment knob 62 with a scale 621, which is connected to the outer housing 61 via a thread (first thread 612). Rotating the knob drives the internal mechanism (e.g., pushing or locking the air intake and smoke exhaust passage 40), thereby enabling fine-tuning and fixing of the passage angle or position. The addition of the scale 621 makes the adjustment process more precise and controllable, allowing doctors to make quantitative adjustments based on the scale.

[0042] In this embodiment, a sealing ring 63 is provided between the outer shell 61 and the adjustment knob 62. The sealing ring 63 is used to seal the air intake and exhaust channel 40. One end of the outer shell 61 is provided with a mounting groove 64 and a plug-in part 65 in sequence. The diameter of the plug-in part 65 gradually decreases along the direction of insertion of the fixing adjustment component 60. The instrument platform 10 is provided with a plug-in groove at a preset position. A protrusion is provided on the side wall of the plug-in groove. When the fixing adjustment component 60 is inserted into the plug-in groove, the protrusion is engaged in the mounting groove 64.

[0043] The smoke exhaust sealing assembly is installed within the fixed adjustment assembly 60 to maintain the airtightness of the system when adjusting the intake and exhaust channels 40, preventing gas or particle leakage.

[0044] During assembly, the tapered insertion part 65 facilitates guidance, and the protrusion is locked when it is inserted into the mounting groove 64, thus achieving a stable, fast and reliable mechanical connection between the adjustment component and the platform.

[0045] In this embodiment, a plurality of first air holes 51 are provided on the side wall of the built-in air intake and exhaust port 50, and a plurality of second air holes 52 are provided at the end of the built-in air intake and exhaust port 50; wherein, the first air holes 51 are connected to the first chamber 31, and the second air holes 52 are connected to the second chamber 32.

[0046] The first vent 51 on the side wall communicates with the first chamber 31 for air intake, mainly responsible for introducing clean gas horizontally or obliquely into the surgical cavity; the second vent 52 at the end communicates with the second chamber 32 for smoke exhaust, mainly responsible for drawing smoke mist from directly in front of the port. This multi-directional vent distribution, especially the distinction between side wall air intake and end smoke exhaust, helps to form a more efficient gas circulation flow field around the port, optimizing local smoke exhaust and ventilation efficiency.

[0047] In this embodiment, the air intake and exhaust interface 30 and the real-time pressure measurement interface 70 are integrated into one unit, or they are set separately as independent interfaces on the instrument platform 10.

[0048] It should be noted that there are two physical layout strategies for the interfaces. The first is an integrated approach, which combines the functions of the air intake / exhaust interface 30 and the real-time pressure measurement interface 70 into a single composite interface, making external pipeline connections more centralized and concise. The second is a separate approach, where the two are set as independent interfaces in different locations on the instrument platform 10. This provides flexibility in product design: the integrated approach simplifies operation and saves space; the separate approach may facilitate modular maintenance or adapt to different surgical equipment connection habits.

[0049] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
