As shown in Figs. 1 to 4, the suction perfusion device 1 is a medical device used in laparoscopic surgery.

The suction perfusion device 1 enters the abdominal cavity B and contacts the organ S and particularly the intestines and mesenteric membranes to thereby suck blood or solution in the abdominal cavity B. During this process, (B) operation can be performed by preventing the distal end from being stuck to the distal end.

More specifically, the suction perfusion device includes a body 3 and an inhalation device 5 disposed inside the distal end portion 5 protruding from one side of the body 3 to suck blood or solution from the abdominal cavity B, And a gas injection unit 13 for injecting gas into the abdominal cavity B to prevent the distal end of the suction perfusion tube 13 from sticking to the organ S, A crotch portion 6 disposed on the inside of the suction perfusion tube 13 so as to be able to move forward and backward to perform cauterization on the organ S; And an operation portion (button portion) 7 for opening and closing the gas injection portion 4.

In the suction-perfusion machine having such a structure, the body 3 has a shape with a handle so that a practitioner can conveniently perform the operation while being held by a hand.

A tip end portion 5 protruding from one side of the body 3 has a double pipe structure, a suction inlet pipe 13 is disposed on the inner side, and a gas injection pipe 11 is disposed on the outer side.

The suction inlet pipe (13) has a tubular shape in which an empty space is formed. One end of the suction inlet pipe 13 communicates with the outside and the other end is selectively connected to the suction duct 25 and the duct 23. At this time, the suction duct 25 and the perfusion duct 23 are connected to a pump (not shown) for generating pressure.

During the laparoscopic procedure, one side of the suction perfusion tube 13 enters the abdominal cavity B and contacts the treatment area such as the organ S and the inside of the suction perfusion tube 13 when the pump (not shown) The blood or solution in the abdominal cavity B can be sucked through the perfusion hole 15 and discharged through the suction duct 25 to the outside.

This suction perfusion tube 13 can also be used for perfusion purposes. That is, when the perfusion button 17 described below is operated, the suction perfusion tube 13 is opened by opening the perfusion duct 23 so that the stored fluid is supplied to the suction perfusion tube 13 by the pressure by the pump (not shown) Lt; / RTI > into the body.

The gas injection unit 4 is provided to prevent the organ S from blocking the perfusion hole 15 by the suction force of the suction perfusion tube 13. [

The gas injection unit 4 has a tubular shape and is configured to surround the suction perfusion tube 13.

The gas injection unit 4 includes a gas injection pipe 11 having a shape disposed on the outside of the suction pipe 13 and serving as a gas passage; A nozzle h formed at one side of the gas injection pipe 11 and through which gas is injected; And a gas duct 21 connected to the other side of the gas injection pipe 11 to supply gas. The injection direction of the nozzle h is parallel to the direction opposite to the suction direction.

The gas injected from the gas injection tube 11 can be injected through the nozzle h and between the organ S in the abdominal cavity B and the gas injection part 4. [ At this time, the gas preferably includes carbon dioxide (CO2).

As described above, by spraying the gas through the nozzle h, it is possible to effectively prevent the organ S from adhering to the perfusion hole 15. In another embodiment, the nozzle h may be additionally formed on the side of the gas injection tube 11 in the periphery of the flow-through hole 15.

The gas duct 21 is connected to an external gas source so that the gas is supplied to the gas injection pipe 11. The gas duct 21 is opened and closed by the button portion 7, so that the gas can be appropriately supplied or cut off, if necessary.

The gas duct 21 is supplied with the gas through the pipe 40 and the pressure regulating part 41 connected to the gas source.

The gas source may be a carbon dioxide gas source supplied into the abdominal cavity during laparoscopic surgery or a separate carbon dioxide tank.

The button portion 7 opens or closes the suction duct 25, the perfusion duct 23, and the gas duct 21. [

More specifically, the button portion 7 includes a housing 18 mounted on the body 3; A suction button (19) arranged vertically to the housing (18) to open and close the suction duct (25); And a perfusion / gas button 17 disposed vertically to the housing 18 for opening and closing the perfusion duct 23 and the gas duct 21. [

In the button portion 7 having such a structure, the suction button 19 has a conventional button structure. That is, when the suction duct 25 is pressed once, the suction duct 25 is closed, and once again, the pressing force is released, thereby opening the suction duct 25. [

Describing in more detail, the suction button 19 is supported on the housing 18. A spring S2 is disposed under the suction button 19 to elastically support the suction button 19 upward.

When the practitioner presses the suction button 19, the spring S2 is compressed. On the contrary, when the pressing force of the suction button 19 is released, the suction button 19 is raised by the elastic force of the spring S2, Return.

At the lower center of the suction button 19, a suction pressure bar 47 for pressing or releasing the suction duct 25 comes into contact with the suction duct 25. When the practitioner presses the suction button 19, the suction pressure bar 47 can be lowered to push the suction duct 25 to close the suction duct 25.

On the contrary, when the operator pushes the suction button 19 one more time, the pushing force of the suction button 19 is released, and the suction button 19 is lifted upward by the elastic force of the spring S2, 47 can be released from contact with the suction duct 25. As a result, since the suction duct 25 is opened, the blood or solution in the abdominal cavity B can be sucked through the suction duct 25.

In this manner, the practitioner can open or close the suction duct 25 by pressing or releasing the suction button 19.

The perfusion / gas button 17 also has a structure similar to the suction button 19. The flow-through button 17 is also supported by the housing 18. A spring S1 is disposed under the flow-through button 17 to elastically support the flow-through button 17. [

At the lower portion of the flow-through button 17, two pressure bars 43 and 45 are protruded. That is, the two pressure bars 43 and 45 include a flow-through pressure bar 45 for pressing or releasing the flow-through duct 23; And a gas pressure bar (43) for pressing or releasing the gas duct (21).

The pressurization bar 45 and the gas pressurization bar 43 are moved upward and downward in cooperation with each other when the flow-through button 17 is pressed. That is, when the flow-through button 17 is depressed, the flow-through pressure bar 45 and the gas pressure bar 43 simultaneously descend to pressurize the flow-through duct 23 and the gas duct 21, respectively.

Conversely, when releasing the force pressing the flow-through button 17, the flow-through pressure bar 45 and the gas pressure bar 43 simultaneously move away from the flow-through duct 23 and the gas duct 21.

As a result, when the practitioner presses the perfusion button 17, the perfusion duct 23 is opened and the fluid is supplied into the abdominal cavity B, and at the same time, the gas can be supplied through the gas duct 21.

The cauterization unit 6 includes an electric rod 37 which is disposed inside the suction perfusion tube 13 so as to be able to move forward and backward so as to perform electrical cauterization for the organ S and the like; A trigger 29 hingedly mounted on the body 3 to advance and retract the electric rod 37 when the operator pulls or pivots; A safety bar 33 for fixing the trigger 29 to the body 3; And an electric plug (27) for supplying electricity to the electric rod (37).

In the cauterization section 6 having such a structure, the electric rod 37 has a diameter that can be disposed inside the suction inlet pipe 13. The electric jaw J is mounted on the tip of the electric rod 37, so that the electric cauterization can be performed more easily.

The rear end of the electric rod 37 is connected to the trigger 29. Therefore, when the practitioner pulls the trigger 29 using a finger or the like, the electric rod 37 can advance to the treatment site by advancing.

The trigger 29 is attached to the body 3 by a hinge pin and a tension spring (not shown) is connected to the rear of the trigger 29 to be fixed to the body 3. Therefore, when the external force is not applied to the trigger 29, for example, when the trigger 29 is not operated, the trigger 29 is pulled back by the tension spring S, so that the electric rod 37 maintains the backward state.

When the trigger 29 is pulled by a finger or the like, the electric rod 37 is advanced. When the trigger 29 is released, the electric rod 37 is moved backward by the tension spring S.

When the cauterization procedure by the electric rod 37 is to be continuously performed, the position of the trigger 29 can be fixed by the safety bar 33 so that the electric rod 37 can be kept in a state of approaching the treatment site.

The safety bar 33 is attached to a lower portion of the body 3 by a hinge pin and a plurality of gear teeth 35 are formed on the upper surface. The gear teeth 35 can be sequentially engaged with the projections 31 protruding from the trigger 29.

The trigger 29 is positioned at a predetermined angle and then the safety bar 33 is rotated so that the projection 31 is engaged with one of the gear teeth 35 of the plurality of gear teeth 35, It can be stably fixed in position.

The electric rod 37 can be applied not only to the unipolar type but also to the bipolar type.

When the electric rod 37 is used in a unipolar fashion, the tongue jaw J mounted on the tip of the electric rod 37 protrudes forward, so that the electric cauterization can be performed. On the other hand, when the electric bar 37 is used in a bipolar manner, electric cautery can be performed by operation of the tongue jaw J.

At this time, by driving the pump, the interior of the suction pipe 13 and the suction duct 25 becomes a sound pressure state.

In this state, when the tip of the suction perfusion tube 13 comes into contact with the treatment site, blood or solution is sucked through the suction perfusion tube 13 by the sound pressure inside the suction perfusion tube 13 and the suction duct 25, .

The suction button 19 of the button portion 7 is depressed and the suction pressure bar 47 is lowered by the descent of the suction button 19 to pressurize the suction duct 25 .

As a result, the suction duct 25 is pushed and closed, and the flow of air discharged through the suction duct 25 is blocked, so that the suction procedure can be interrupted.

The suction button 19 is lifted by the elastic force of the spring S2 so that the suction pressure bar 47 is lifted by the suction duct 19 25 so that the negative pressure can be maintained constantly.

When the organ S adheres to the tip of the suction perfusion tube 13 due to a pressure difference during the inhalation procedure, the gas is injected into the peritoneal cavity B through the gas injection tube 11 to prevent it.

As described above, the gas injected between the organ S and the tip 5 through the plurality of nozzles h prevents the organ S from blocking the perfusion hole 15 by the suction force of the suction perfusion tube 13 can do.

If the gas injection is to be stopped, the flow-through button 17 of the button portion 7 is pressed again. When the perfusion button 17 is further depressed as described above, the perfusion pressure bar 45 and the gas pressure bar 43 are lowered to thereby pressurize the perfusion duct 23 and the gas duct 21 to be closed.

On the other hand, when the electric cauterization is performed, the safety bar 33 is released and the trigger 29 is pulled backward. When the trigger 29 is pulled, the electric rod 37 advances and reaches the treatment site. At this time, electric power is supplied to the electric rod 37.

The electrocautery can be performed by the contact of the electric rod 37 with the treatment site.

A second embodiment of the present invention will be described with reference to Fig.

In the second embodiment, the opening and closing of the gas duct 21 and the suction duct 25 are simultaneously determined by the operation of the suction button 19. [ When the suction operation is required, suction and gas injection can be simultaneously performed by operating the suction button (19).

In this case, it is possible to prevent the organs from blocking the perfusion hole 15 by the gas injection, and simultaneously perform the suction operation. Therefore, the suction operation is simplified as compared with the first embodiment.

In another embodiment, the opening and closing of the gas duct 21 and the opening and closing of the suction duct 25 can be configured independently.

A third embodiment of the present invention will be described with reference to Fig.

In the third embodiment, the flow rate of the gas injection is changed by the operation of the operating portion (button portion) 7. The gas injection intensity that can prevent clogging of the perfusion hole 15 upon inhalation may be different depending on the operation state and the like. In the third embodiment, the gas injection intensity can be adjusted and the appropriate gas injection intensity can be selected.

In another embodiment, the flow rate of the gas injection may be selected in three or more stages, or the gas injection flow rate may be continuously changed.
