Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an intraoperative cooling device. Background Art

[0002] Our hospital's neurosurgery and orthopedic spine surgeries all use power systems, such as craniotomy drills, milling cutters, and grinding drills. During use, the drill bit rotates at high speed and rubs against bone tissue, so heat cannot be transferred in time.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] See also Figure 1 The schematic diagram of the structure of an intraoperative cooling device is shown, wherein the intraoperative cooling device comprises a cooling pipeline 1, a flow regulating switch 2 and a flushing head 3;

[0040] The first end of the cooling pipeline 1 is provided with a connector 4, and the connector 4 is connected to a first container, and the first container contains cooling liquid;

[0041] The cooling pipeline 1 is provided with a flow regulating switch 2, and the flow regulating switch 2 is used to adjust the flow of the cooling liquid in the cooling pipeline 1;

[0042] A soft flushing head 3 is provided at the second end of the cooling pipeline 1 .

[0043] Exemplarily, the first container can be a medical glass hanging bottle or a medical plastic hanging bottle, etc. The cooling liquid can be physiological saline or clean water, etc., which can be selected as needed.

[0044] Exemplarily, the flow regulating switch 2 can be an infusion flow regulator on an infusion hose of a hospital hanging bottle infusion, and the material of the soft flushing head 3 can be soft plastic or rubber or other materials.

[0045] The above-mentioned flushing head 3 is used to release cooling liquid to the surgical area to cool the surgical area. The flushing head 3 is made of soft material to avoid damaging human tissue in the surgical area.

[0046] The present application does not adopt the method of nurses frequently passing syringes to flush the surgical area with the syringes. Instead, the cooling pipeline 1 is connected to a first container containing cooling liquid, the cooling liquid is discharged, and the flushing head 3 is used to flush the surgical area to be cooled. Extending the flushing time can better and continuously cool the surgical area, and reduce the number of times the syringe is replaced. The operation is convenient. In addition, the flow rate of the cooling liquid for flushing the surgical area can be adjusted by the flow regulating switch 2, which is convenient to use.

[0047] Optionally, the cooling pipeline 1 is also provided with a first switch for controlling the conduction of the cooling pipeline 1 .

[0048] For example, the first switch can be a clamp, and when the cooling pipeline 1 needs to stop delivering cooling liquid, the clamp can be used to clamp the folded hose area of ​​the cooling pipeline 1. Conversely, when the cooling pipeline 1 needs to deliver cooling liquid, the clamp can be removed from the cooling hose.

[0049] Optional, see Figure 2 The structural schematic diagram of another intraoperative cooling device is shown. The above device may also include a gripping member 6, and the gripping member 6 is fixed to the cooling pipeline 1 near the flushing head 3.

[0051] For example, when the surgeon is performing deep surgery, the light used for illumination can be turned on, so that the surgeon can see the surgical field more clearly and avoid accidental injury to surrounding blood vessels, nerves, etc.

[0052] Optionally, the holding piece 6 is provided with a first mounting groove 63 for the lamp 7, the opening end of the first mounting groove 63 is provided at one end of the holding piece 6 close to the flushing head 3, a transparent cover 8 is fixed to the opening end of the first mounting groove 63, and the transparent cover 8 is sealedly connected to the holding piece 6.

[0053] For example, the sealed connection can be achieved by providing rubber pads between the transparent cover 8 and the gripping member 6, and by providing screws to press the transparent cover 8 and the rubber pads onto the gripping member 6. Of course, a sealant can also be used to connect and seal the gap between the transparent cover 8 and the gripping member 6. Even if the cooling liquid is released to the surgical area, the splashed cooling liquid falls on the transparent cover 8, which is convenient to wipe and handle, and also reduces the influence of the cooling liquid on the circuit connected to the lamp 7.

[0054] Optionally, when the lamp 7 is connected to a power source via a USB interface 71 , the holding piece 6 is provided with a first via hole 64 for a connection line between the lamp 7 and the USB interface 71 .

[0055] Exemplarily, the lamp 7 can be powered by a power source connected to a USB interface 71, or by a battery. When the USB interface 71 is used for power supply, the grip 6 is provided with a first via 64 for the line between the USB interface 71 and the lamp 7. This facilitates the USB interface 71 to connect to a power source to power the lamp 7.

[0064] Optionally, the first end of the flushing head 3 is connected to the second end of the hard tube 12, and the second end of the flushing head 3 is provided with a water outlet;

[0065] Both end surfaces of the hard tube 12 are chamfered with the outer side wall of the hard tube 12 , respectively, and the outer diameter of the hard tube 12 corresponds to the inner diameter of the first soft tube.

[0066] Exemplarily, the first hose is made of a plastic or rubber hose with a certain elasticity, the minimum outer diameter of the hard tube 12 corresponds to the inner diameter of the first hose, and the first hose is expanded and wrapped around the first end of the hard tube 12, and connected to the hard tube 12, so that the inner wall of the hose is pressed against the outer wall of the hard tube 12, and is closely connected to the outer wall of the hard tube 12, thereby improving the sealing effect between the hose and the hard tube 12. Similarly, the structure of the connection between the first end of the flushing head 3 and the second end of the hard tube 12 is the same as the structure of the connection between the second end of the first hose and the first end of the hard tube 12.

[0067] Optional, see Figure 4 , see Figure 6 A structural schematic diagram of a hard tube and a first hose being installed by a clamping member and Figure 7 A schematic diagram of a structure in which a first annular plate and a second annular plate are arranged correspondingly is shown.
