Description

Technical Field

[0001] The invention belongs to the technical field of surgical instruments, and in particular relates to a self-circulating smoke removal pipeline system in laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is a surgical method in which instruments are placed into the human body's cavity through tiny incisions, and then the diseases in the cavity are examined, diagnosing and treating using a television screen. The principle is to use modern optics, electronics, mechanics and other high-tech means to deliver surgical instruments and cameras into the human body through tiny incisions. The doctor can clearly observe the situation in the surgical area through the real-time images on the TV screen and perform precise surgical operations.

[0003] Laparoscopic surgery usually involves making several small incisions of five to ten millimeters in the abdomen or chest, through which a laparoscope and special surgical tools are inserted. However, in actual operations, various energy instruments in laparoscopic surgery are prone to produce smoke, which can affect the surgical field of view. Existing smoke exhaust methods mainly involve directly opening the puncture card exhaust holes to discharge the smoke into the air in the operating room, but this can endanger the health of the operator; or using an aspirator or a smoke exhaust and pressure-stabilizing insufflator to remove smoke, but the equipment is expensive and the operation is cumbersome, so improvements are needed. Summary of the invention

[0004] The purpose of the present invention is to provide a self-circulating smoke removal pipeline system in laparoscopic surgery to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a self-circulating smoke removal pipeline system for laparoscopic surgery, comprising a long tube, a transition tube is fixedly sleeved at the bottom end of the long tube, a first one-way valve is fixedly installed at the right end of the transition tube, a second one-way valve is fixedly installed at the left end of the transition tube, a negative pressure tube is fixedly installed at the right end of the first one-way valve, an air intake pipe is fixedly installed at the left end of the second one-way valve, a filter is fixedly installed at the top end of the long tube, a connecting tube is fixedly installed at the middle part of the top end of the filter, a negative pressure pump is fixedly installed at the other end of the connecting tube, a return air pipe is fixedly installed at the bottom end of the negative pressure pump, the bottom end of the return air pipe passes through the air intake pipe and extends to the interior of the air intake pipe, and the outer surface of the return air pipe and the inner surface of the top end of the air intake pipe are fixedly sleeved.

[0006] As a preferred embodiment of the present invention, the tops of the outer surfaces of the negative pressure pipe and the air inlet pipe are respectively fixedly sleeved with fixing rings, and the inner parts of the fixing rings are movably sleeved with circular rings.

[0007] As a preferred embodiment of the present invention, a connecting block is fixedly installed on the outer surface of the circular ring, and a supporting block is fixedly installed on the other end of the connecting block.

[0008] As a preferred embodiment of the present invention, movable blocks are movably sleeved on the left and right sides of the middle end of the support block, and a tooth plate is fixedly installed on the rear end of the movable block. The outer surface of the tooth plate is movably connected to the outer surface of the support block.

[0009] As a preferred embodiment of the present invention, the movable block is internally movablely sleeved with a limit rod, the left and right sides of the outer surface of the limit rod are respectively fixedly sleeved with the inner surfaces of the left and right ends of the support block, and a spring located outside the limit rod is fixedly installed on one side of the outer surface of the movable block away from the center position of the support block, and the other end of the spring is fixedly connected to the inner surface of the support block.

[0010] As a preferred embodiment of the present invention, a top end of the movable block is hinged with an inclined plate, and the other end of the inclined plate is hinged with a rectangular block.

[0011] As a preferred embodiment of the present invention, a square column is movably sleeved inside the rectangular block, the bottom end of the square column is fixedly connected to the top end of the support block, a stopper is fixedly installed on the top end of the square column, and the bottom end of the stopper is movably connected to the top end of the rectangular block.

[0012] As a preferred embodiment of the present invention, the first one-way valve and the second one-way valve are identical in shape and size, and the first one-way valve and the second one-way valve allow the same gas flow direction.

[0013] As a preferred embodiment of the present invention, the long tube, the transition tube, the first one-way valve and the negative pressure tube constitute a negative pressure pipeline, and the return air pipe, the second one-way valve and the intake pipe constitute an intake pipeline.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides a long tube, a negative pressure tube, a negative pressure pump and an air intake pipe. When the negative pressure pump is started, the smoke in the abdominal cavity will pass through the negative pressure tube, the transition tube and the long tube and enter the negative pressure pump through the connecting tube after being filtered by the filter, and then be transported back to the abdominal cavity through the return pipe and the air intake pipe, thereby realizing self-circulating closed-loop smoke removal, thereby effectively reducing the retention time of harmful smoke in the body, ensuring the cleanliness of the surgical field, and at the same time, no human intervention is required, eliminating the need for surgical personnel to manually exhaust smoke, and ensuring the continuity of the operation.

[0016] 2. The present invention arranges a movable block, a tooth plate, a spring, an inclined plate and a rectangular block. When the rectangular block is pressed, the rectangular block will move along the outer surface of the square column with one end of the inclined plate, so that the other end of the inclined plate generates a thrust on the movable block, pushing the movable block to move along the outer surface of the limit rod with the tooth plate and compressing the spring. Under the restoring action of the spring, the movable block and the tooth plate will be forced to return to their original positions, so that the pipeline is fixed to the rod of various energy instruments through the tooth plate, preventing the pipeline from falling off due to the operation of various energy instruments during surgery.

[0017] 3. The present invention sets a first one-way valve and a second one-way valve. The first one-way valve and the second one-way valve cooperate with each other to ensure that the negative pressure pipeline composed of the long tube, the transition tube, the first one-way valve and the negative pressure tube and the air intake pipeline composed of the return pipe, the second one-way valve and the air intake pipe will not interfere with each other. The automatic circulation and cleaning of the gas in the abdominal cavity can be achieved through the blowing and exhausting of the cavity through the air intake pipeline and the negative pressure pipeline. Compared with the expensive smoke exhaust and pressure-stabilizing insufflator, the cost is low and it is easier to popularize and promote. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 7As shown, an embodiment of the present invention provides a self-circulating smoke removal pipeline system for laparoscopic surgery, comprising a long tube 1, a transition tube 2 is fixedly sleeved at the bottom end of the long tube 1, a first one-way valve 3 is fixedly installed at the right end of the transition tube 2, a second one-way valve 4 is fixedly installed at the left end of the transition tube 2, a negative pressure tube 5 is fixedly installed at the right end of the first one-way valve 3, an air intake pipe 6 is fixedly installed at the left end of the second one-way valve 4, a filter 7 is fixedly installed at the top end of the long tube 1, a connecting tube 8 is fixedly installed at the middle part of the top end of the filter 7, a negative pressure pump 9 is fixedly installed at the other end of the connecting tube 8, a return air pipe 10 is fixedly installed at the bottom end of the negative pressure pump 9, the bottom end of the return air pipe 10 passes through the air intake pipe 6 and extends to the interior of the air intake pipe 6, and the outer surface of the return air pipe 10 and the inner surface of the top end of the air intake pipe 6 are fixedly sleeved.

[0028] When the negative pressure pump 9 is started, the smoke inside the abdominal cavity will enter the transition pipe 2 through the negative pressure pipe 5 and the first one-way valve 3, and then enter the negative pressure pump 9 through the long pipe 1, the filter 7 and the connecting pipe 8, and finally be transported back to the abdominal cavity through the return air pipe 10 and the intake air pipe 6. At the same time, the filter interlayer such as activated carbon loaded inside the filter 7 can effectively filter the smoke as the smoke passes through, so that self-circulating smoke removal can be achieved, thereby effectively reducing the residence time of harmful smoke in the body and ensuring the cleanliness of the surgical field. At the same time, it can also save the operator from manual smoke exhaust, so that the operator can maintain the continuity of the operation during laparoscopic surgery.

[0029] The tops of the outer surfaces of the negative pressure pipe 5 and the air inlet pipe 6 are respectively fixedly sleeved with fixing rings 11 , and the inner parts of the fixing rings 11 are movably sleeved with a circular ring 12 .

[0030] The inner surface of the fixing ring 11 and the outer surface of the circular ring 12 are both smooth, thereby ensuring that the circular ring 12 will not get stuck when rotating along the inside of the fixing ring 11, thereby facilitating the adjustment of the position of the circular ring 12. At the same time, the existence of the fixing ring 11 will support and fix the circular ring 12.

[0031] A connecting block 13 is fixedly mounted on the outer surface of the circular ring 12 , and a supporting block 14 is fixedly mounted on the other end of the connecting block 13 .

[0032] Due to the existence of the connecting block 13, it will be used to connect the circular ring 12 and the supporting block 14, so as to ensure that the supporting block 14 can rotate along with the circular ring 12 with the fixing ring 11 as the axis.

[0033] The movable blocks 15 are movably sleeved on the left and right sides of the middle end of the support block 14 , and a tooth plate 16 is fixedly installed on the rear end of the movable block 15 . The outer surface of the tooth plate 16 is movably connected to the outer surface of the support block 14 .

[0034] When the movable block 15 moves along the inner surface of the support block 14, the tooth plate 16 fixedly connected to the movable block 15 will move along with it. At the same time, the outer surface of the tooth plate 16 is provided with trapezoidal teeth, so that the negative pressure tube 5 and the air intake pipe 6 can be fixed to various energy instrument rods through the tooth plate 16 to prevent them from falling off.

[0035] Among them, the movable block 15 is internally movablely sleeved with a limit rod 17, and the left and right sides of the outer surface of the limit rod 17 are fixedly sleeved with the inner surfaces of the left and right ends of the support block 14 respectively, and a spring 18 located outside the limit rod 17 is fixedly installed on one side of the outer surface of the movable block 15 away from the center position of the support block 14, and the other end of the spring 18 is fixedly connected to the inner surface of the support block 14.

[0036] Due to the existence of the limit rod 17, the movement of the movable block 15 will be restricted, thereby ensuring the stability of the movable block 15 moving inside the support block 14. When the movable block 15 moves, the spring 18 will be compressed, thereby forcing the movable block 15 to return to its original position under the restoring action of the spring 18.

[0037] The top end of the movable block 15 is hinged with an inclined plate 19 , and the other end of the inclined plate 19 is hinged with a rectangular block 20 .

[0038] When the rectangular block 20 moves, since the upper and lower ends of the inclined plate 19 are hinged to the rectangular block 20 and the movable block 15 respectively, as the rectangular block 20 moves, the top end of the inclined plate 19 will move along with the rectangular block 20, so that the bottom end of the inclined plate 19 generates a thrust on the movable block 15, pushing the movable block 15 to move along the inner surface of the support block 14 with the tooth plate 16.

[0039] The rectangular block 20 has a square column 21 movably sleeved inside, the bottom of the square column 21 is fixedly connected to the top of the support block 14 , a stopper 22 is fixedly installed on the top of the square column 21 , and the bottom of the stopper 22 is movably connected to the top of the rectangular block 20 .

[0040] The presence of the square pillar 21 will restrict the movement of the rectangular block 20, thereby preventing the rectangular block 20 from deviating during the movement, while the presence of the stopper 22 plays a role of auxiliary limiting.

[0041] The first one-way valve 3 and the second one-way valve 4 have the same shape and size, and the first one-way valve 3 and the second one-way valve 4 allow the same flow direction of gas.

[0042] Due to the presence of the first one-way valve 3, the smoke is allowed to enter the transition pipe 2 from the negative pressure pipe 5, while the presence of the second one-way valve 4 can prevent the filtered gas from entering the transition pipe 2 from the intake pipe 6. The mutual cooperation between the first one-way valve 3 and the second one-way valve 4 ensures the self-circulation of the smoke removal pipeline.

[0043] Among them, the long tube 1, the transition tube 2, the first one-way valve 3 and the negative pressure tube 5 constitute a negative pressure pipeline, and the return air pipe 10, the second one-way valve 4 and the intake pipe 6 constitute an intake pipeline.

[0044] The blowing and draining of the air inlet and negative pressure lines can achieve automatic circulation of gas in the abdominal cavity, eliminating the need for human intervention and ensuring the continuity of the operation.

[0045] Working principle and usage process:

[0046] When in use, the operator first inserts the negative pressure tube 5 and the air intake tube 6 into the pre-opened abdominal opening respectively, and then presses the rectangular block 20, so that the rectangular block 20 moves downward along the outer surface of the square column 21 with the top of the inclined plate 19, so that the bottom end of the inclined plate 19 generates a thrust on the movable block 15, pushing the movable block 15 to move along the inner surface of the support block 14 with the tooth plate 16 and compressing the spring 18, thereby opening the tooth plate 16, and then placing the opened tooth plate 16 on the energy instrument rod and releasing the rectangular block 20. At this time, under the restoring action of the spring 18, the movable block 15 and the tooth plate 16 will be restored to their original positions and the negative pressure tube 5 and the air intake tube 6 will be clamped and fixed, thereby preventing them from falling off during surgery.

[0047] Subsequently, the operator starts the negative pressure pump 9, so that the smoke inside the abdominal cavity passes through the negative pressure tube 5, the first one-way valve 3, the transition tube 2 and the long tube 1 and enters the connecting tube 8 and the negative pressure pump 9 after being filtered by the filter 7, and then is transported back to the abdominal cavity through the return pipe 10 and the intake pipe 6, thereby realizing self-circulating closed-loop smoke removal, thereby effectively reducing the residence time of harmful smoke in the body, ensuring the cleanliness of the surgical field, and at the same time, without the need for human intervention, eliminating the need for manual smoke exhaust by the surgical staff, ensuring the continuity of the operation, and ensuring the safety and progress of the operation.

[0048] In addition, compared with the suction device and the smoke exhaust and pressure-stabilizing insufflator, the self-circulating smoke removal pipeline composed of the negative pressure tube 5, the first one-way valve 3, the transition tube 2, the long tube 1, the filter 7, the negative pressure pump 9, the return air pipe 10, the second one-way valve 4 and the air intake pipe 6 is cheaper and easier to popularize.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
