Description

  The present invention relates to a water injection and suction device capable of simultaneously injecting water such as physiological saline into an operation part and discharging the injected physiological saline with a single handpiece during an animal or human operation. .

  When performing surgery on animals or humans, it is performed while injecting physiological saline into the surgical site, and at the same time, the injected physiological saline or blood that has been bleeding due to surgery is also aspirated and discharged.

  However, in the conventional apparatus, water injection and suction are all performed by separate apparatuses. For example, it is not possible to perform work such as suction and drainage while pouring water alone.

  The present invention has been made in view of the above-described circumstances, and in particular, it is possible to perform water injection and suction drainage simultaneously with a single instrument (handpiece), that is, water injection and suction drainage alone. In addition to reducing the number of people required for surgery (reducing the number of people around the surgery) and making it easier to perform surgery, water injection and suction drainage can be effectively performed to improve work efficiency. Is intended.

  The invention of claim 1 integrally includes a water injection pipe and a suction pipe having an outside air communication hole, the water injection pipe is connected to a water injection bottle, the suction pipe is connected to an intake device, and water is injected from the tip of the water injection pipe. Then, the amount of water absorption from the tip of the suction pipe is adjusted by adjusting the degree of opening of the outside air communication hole.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the tip of the suction pipe protrudes forward from the tip of the water injection pipe.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the suction tube has a connecting portion in front of the outside air communication hole, and a plurality of types of suction tip tubes having different diameters are exchanged at the connecting portion It is characterized by being able to be connected.

  The invention of claim 4 is the invention according to any one of claims 1 to 3, wherein the water injection bottle is suspended at a high place, and the water injection is performed by the head pressure (head pressure). It is what.

  The invention of claim 5 is characterized in that, in the invention of claim 4, the water injection pipe has a cock, and the amount of water injection is adjusted by adjusting the opening of the cock.

  The invention of claim 6 is the invention according to any one of claims 1 to 3, wherein the water injection bottle is connected to a water supply device, and the water injection is performed by the water supply device. .

  According to the present invention, water injection and suction drainage can be performed simultaneously with a single instrument (handpiece), that is, since water injection and suction drainage can be performed by one person, the number of people required for surgery can be reduced. Therefore, it is possible to reduce the number of personnel around the operation, facilitate the operation work, and improve the work efficiency.

  FIG. 1 is a schematic view for explaining an embodiment of a water injection / suction apparatus according to the present invention. In the figure, 10 is a water injection / suction apparatus (handpiece) according to the present invention. It consists of a water injection pipe 11 for injecting physiological saline and a suction drain pipe 12 for sucking and discharging the injected physiological saline, blood that has bleed due to surgery, and the like. The water injection pipe 11 is integrally joined, for example, by welding.

  The distal end 12a of the suction drain pipe 12 protrudes further forward than the distal end 11a of the water injection pipe 11, so that the distal end 12a of the suction drain pipe 12 approaches the living tissue without being obstructed by the distal end 11a of the water injection pipe 11. This makes it easier to perform water injection and suction. 21 is a water injection hose, 22 is a suction drainage hose, 30 is a water injection / suction drainage device, and the water injection / suction drainage device 30 is used to store a water injection bottle for storing physiological saline or the like, A drainage tank and the like are housed, and further, a water supply device (for example, a tube pump) for sending physiological saline in the water injection bottle to the water injection hose 21 and a suction device (for example, a suction device for sucking the inside of the suction drainage hose 22) Vacuum pump) and the like.

FIG. 2 is a view showing a state when the water injection / suction device (handpiece) 10 shown in FIG. 1 is separated from the water injection hose 21 and the suction / drainage hose 22. Etc., and the diameter of the suction tip tube can be changed according to the amount of suction. The example shown in FIG. 2 shows three suction tip tubes having different tube diameters 12 ₁ , 12 ₂ , and 12 ₃ , which are appropriately selected according to the amount of physiological saline used and the like. Used in conjunction with a drain pipe. FIG. 1 shows an example in which water injection is performed by the water supply device in the water injection / suction drainage device 30. However, as shown by the dotted line 40 in FIG. In addition, it may be hung at a high place and injected using head pressure (water pressure).

  12b is a hole for external air communication provided in a part of the suction drain pipe 12, and this hole 12b communicates with a flow path in the suction drain pipe 12. Normally, this hole 12b is the suction drain pipe 12. Since it is in communication with the internal flow path, the air is sucked through the hole 12b, and even if the suction device (vacuum device) is driven, there is no suction from the tip 12a of the suction drain pipe 12, and the hole 12b is blocked. At this time, suction from the tip 12a of the suction drain pipe 12 is performed. The suction force can be adjusted depending on how the hole 12b is blocked.

  Moreover, 11b is a cock provided in the water injection pipe | tube 11, and can adjust the opening degree of this cock, and can adjust the amount of water injection by this. In particular, as shown by a dotted line 40 in FIG. 1, it is preferable in a case where the water injection bottle 40 is suspended at a high place and water is injected using a head pressure (high / low differential pressure). However, the cock 11b is not necessarily required when using a water supply device that delivers a predetermined flow rate (hourly) such as a tube pump.

It is a figure for demonstrating the usage example of the water injection suction apparatus by this invention. It is detail drawing of the water injection suction device by this invention.
