Description

Technical Field

[0001] This patent relates to the field of medical devices for assisting laparoscopic surgery. Background Technology

[0002] With the development of minimally invasive medical technology, disposable multi-channel single-port laparoscopic surgery is a more minimally invasive and aesthetically pleasing procedure. Unlike conventional laparoscopy, it involves entering the body through a single incision and inserting laparoscopic instruments through multiple channels. An insufflator provides air pressure, and carbon dioxide gas is introduced through the air intake channel on the operating platform to expand the cavity, providing suitable surgical space and a wide surgical field. Both the endoscope and conventional surgical instruments are inserted through the multi-channel single-port laparoscopic surgical trocar. During the procedure, electrocoagulation, hemostasis, and electrocautery of tissues are required, but these processes generate large amounts of smoke and water vapor, affecting the surgical field. The multi-port cap of the disposable multi-channel single-port laparoscopic surgical trocar has its own air intake and suction devices, resulting in poor smoke extraction.

[0003] The main reason is that when smoke is generated at the electrocoagulation site, it first spreads into the cavity. The porous cover has an intake valve that continuously injects fresh carbon dioxide gas, and an exhaust valve connected to a negative pressure suction device. Because both the intake and exhaust ports are located in single-hole sections, there is no effective gas circulation between the intake port, the point where smoke is generated in the surgical field, and the exhaust port. However, to maintain cavity expansion, the exhaust flow valve cannot be opened too wide, and most of the carbon dioxide gas that just entered through the intake pipe is sucked away by the exhaust pipe during smoke extraction. This means that the smoke generated in the cavity requires a long period of replacement to dissipate. Currently, most methods use long, non-extendable or non-foldable tubes for smoke extraction, which affects surgical procedures. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by employing a short-tube air intake and a long-tube deep inhalation circulation mechanism. This creates an effective fresh air exchange system between the air inlet, smoke generation point, and smoke extraction port. The long tube is either a telescopic or foldable telescopic smoke extraction tube. The telescopic smoke extraction tube consists of a connection port, an anti-dislodgement ring, side wall smoke extraction holes, a top anti-clogging hole, and a follow-up traction ring. The telescopic smoke extraction tube penetrates the smoke extraction tube sealing sheath. The anti-dislodgement ring is a protruding structure on the outer wall of the tube, located inside the sealing sheath, ensuring that the tube is not excessively pulled out during telescopic movement. Multiple smoke extraction holes are located around the smoke extraction tube, efficiently removing smoke generated by coagulation or electrosurgical resection. It can also be used to clamp the traction ring or follow the smoke extraction with the front end of a parallel instrument forceps, ensuring a clear surgical field and operational safety.

[0005] The present invention adopts the following technical solution to solve the technical problem: A telescopic smoking device for a multi-channel single-port laparoscopic surgical puncture device is characterized by comprising an air inlet tube (1), a smoking device (2), an electrocoagulation device (3), an endoscope (4), a multi-hole cover (5), and an incision protection sleeve (54). The air inlet tube (1) and the smoking device (2) are both installed through the gel cap (52) of the multi-hole cover. The exhaust pipe (22) of the smoking device (2) is connected to a telescopic and stretchable smoking tube (23) or a foldable telescopic smoking tube (24). The multi-hole cover (5) is connected to the abdominal wall via a connecting seat (53) and an incision protection sleeve (54).

[0006] A telescopic smoking device for a multi-channel single-port laparoscopic surgical puncture device is characterized in that the smoking device (2) consists of a flow control valve (21), an exhaust adapter (22), a telescopic and stretchable smoking tube (23) or a foldable telescopic smoking tube (24), an external tube (25), and a negative pressure suction device (26), wherein the exhaust adapter (22) is connected to the telescopic and stretchable smoking tube (23), the telescopic and stretchable smoking tube (23) passes through a smoking tube sealing sheath (232), and the smoking tube sealing sheath (232) is installed on the colloid cap (52) of the multi-hole cover (5).

[0007] A telescopic smoking device for a multi-channel single-port laparoscopic surgical puncture device is characterized in that the telescopic smoking tube (23) is a hollow tubular structure, consisting of a connecting port (231), an anti-dislodgement ring (233), a side wall smoke exhaust hole (234), a top anti-closing hole (235), and a following traction ring (236). The telescopic smoking tube (23) passes through the smoke tube sealing sheath (232). The anti-dislodgement ring (233) is a protruding structure on the outer wall of the telescopic smoking tube (23) and is located inside the smoke tube sealing sheath (232), which can ensure that the telescopic smoking tube (23) is not excessively pulled out and slipped during telescopic sliding.

[0008] A telescopic smoking device for a multi-channel single-port laparoscopic surgical trocar is characterized in that the smoking tube sealing sheath (232) is a tubular structure, consisting of an installation and fixing groove (2321), a sealing ring (2322), and a conical step (2323). The installation and fixing groove (2321) is installed and fixed on the colloid cap (52) of the multi-hole cover. The telescopic smoking tube (23) passes through the smoking tube sealing sheath (232), and the sealing ring (2322) surrounds and seals the wall of the telescopic smoking tube (23).

[0009] A telescopic smoking device for a multi-channel single-port laparoscopic surgical puncture device is characterized in that the foldable telescopic smoking tube (24) is a hollow tubular structure, consisting of an anti-detachment mounting port (241), a foldable telescopic corrugated tube (242), an anti-bend suction tube (243), an anti-bend side wall smoke exhaust hole (244), an anti-bend top anti-closing hole (245), and an anti-bend following traction ring (246). The anti-detachment mounting port (241) is connected to the exhaust adapter tube (22), and the exhaust adapter tube (22) is fixedly installed on the colloid cap (52) of the multi-hole cover. The foldable telescopic corrugated tube (242) is a foldable tube that can be stretched to different lengths. The anti-bend side wall smoke exhaust holes (244) are evenly distributed at the front end of the anti-bend suction tube (243), and the anti-bend following traction ring (246) is located on the side wall of the anti-bend suction tube (243).

[0010] A telescopic smoking device for a multi-channel single-port laparoscopic surgical trocar is characterized in that when the folded telescopic corrugated tube (242) is pulled by the anti-bend follow-up traction ring (246) to the anti-bend suction tube (243), it can not only be stretched to a specified length according to the operation needs, but also be positioned to the required curvature, which facilitates safe operation of the surgery. The anti-bend follow-up traction ring (246) is provided with an elastic clamping instrument hole to facilitate instrument-assisted operation. The anti-bend top anti-closing hole (245) has a rounded corner on the outer periphery to effectively prevent tissue scratching. The port is provided with a cross-shaped semi-circular arc in the radial direction. When the top plane is closed by tissue, air can also be introduced and smoked through the semi-circular hole.

[0011] Compared with existing technologies, the beneficial effects of this invention are reflected in: Based on the existing multi-hole cover air intake and smoke exhaust circulation, a circulation ventilation mechanism of short tube air intake and long tube extension for deep inhalation is adopted. The long tube is a telescopic smoking tube or an automatically folding and adjustable telescopic built-in smoking tube, which makes it easy to extend the smoking tube opening to the appropriate position for smoking as needed. In addition, multiple smoke exhaust holes are evenly arranged around the front end of the smoking tube wall, which can form a corresponding and uniform flow exhaust hole with the frontmost tube opening. This not only allows for flexible adjustment of the distance to efficiently suck out the smoke generated by coagulation or electrocautery in a timely manner, but also allows for clamping traction coils or wearing parallel instrument forceps to follow the smoke as needed, ensuring the clarity of the surgical field and the safety of the surgical operation.

[0016] Taking single-port laparoscopic surgery via the umbilicus as an example, an incision is made on the abdominal wall (6), and the insertion ring (541) of the protective sleeve is inserted. The outer ring is flipped to tighten the incision protective sleeve (54). A multi-hole cover (5) with a telescopic smoking tube (23) or a foldable telescopic smoking tube (24) is installed through the connecting seat (53). The air inlet tube (1) is connected to inflate the abdominal cavity. The abdominal cavity is connected to the colloid cap (52) of the multi-hole cover and expands under high pressure. The exhaust pipe (22) is connected to the outer pipe (25) and the negative pressure suction device (26). The flow control valve (21) is closed.

[0017] The endoscope (4) and the operating instruments (3) enter the abdominal cavity through the large and small multi-channel (51) respectively, and the abdominal cavity is operated on under the visual state. At this time, the anti-dislodgement ring (233) of the telescopic smoking tube is in the external pull anti-dislodgement state or the foldable telescopic smoking tube (24) is in the retracted state, behind the endoscope viewing port, without affecting the surgical field of vision and operation.

[0018] When the surgical site (7) requires electrocoagulation hemostasis or electrocautery, the instrument can be used to clamp the following traction ring (236) to stretch the anti-closing hole (235) at the top of the telescopic smoking tube (23) or the foldable telescopic smoking tube (24) to the appropriate position of the surgery. The bending and shaping will not affect the surgical field of view. The flow control valve (21) is opened to absorb the smoke generated during electrocoagulation or electrocautery.

[0019] During the electrocoagulation or electrocautery stage of the surgery, the air inlet tube (1) and the smoking device (2) are normally open. The smoke generated by the coagulation of tissue by the head of the electrocoagulation device (3) will be sucked away by the negative pressure of the smoke exhaust hole (234) and the anti-clogging hole (235) on the side wall of the nearby stretching smoking tube (23) or folding telescopic smoking tube (24) as it floats upward. The carbon dioxide newly introduced from the inlet tube (1) forms a fresh air exchange system from top to bottom until it reaches the anti-clogging hole (235) of the stretching smoking tube (23) or folding telescopic smoking tube (24). This system can efficiently remove the smoke generated by coagulation or electrocautery in a timely manner, ensuring the clarity of the surgical field and the safety of the surgical operation.
