DETAILED DESCRIPTION

[0029] Embodiments of the present invention will now be described with reference to the accompanying drawings, in which like reference numerals represent like elements.

[0030] Please refer to Figure 1-4 The milling cutter cooler comprises a saline delivery tube 1 connected to a saline bag, and the saline delivery tube 1 is made of soft PVC material. A saline speed regulator 2 is provided in the middle of the saline delivery tube 1. The upper end of the saline delivery tube 1 is connected to a sharp puncture portion 3, and the sharp puncture portion 3 is made of hard PVC material. The internal channel of the saline delivery tube 1 passes through the sharp puncture portion 3, the upper end of the sharp puncture portion 3 is the water inlet end, and the lower end of the saline delivery tube 1 is the water outlet end. The outer periphery of the saline delivery tube 1 is movably covered with a fixing part 4 at a position close to the lower end, and the fixing part 4 is provided with a C-shaped clamping cavity 41 for clamping and fixing the milling cutter handle part, and the two opposite side walls of the C-shaped clamping cavity 41 are elastic. The design of the C-shaped clamping cavity 41 allows the milling cutter handle to be quickly clamped in.

[0031] The brine speed regulator 2 includes a main body 21 that is movably sleeved on the brine delivery pipe 1. The main body 21 has an inner cavity, the bottom wall of the inner cavity is an inclined wall, the inner cavity passes through both ends of the main body 21 along the axial direction of the brine delivery pipe 1, the brine delivery pipe 1 passes through the inner cavity, and the inner cavity also passes through the side of the main body 21 to form a notch, a pushing wheel 22 is installed in the inner cavity, and the brine delivery pipe 1 is located between the inclined wall and the pushing wheel 22. The pushing wheel 22 can move along the length direction of the notch to squeeze or release the brine delivery pipe 1. When the pushing wheel 22 squeezes the brine delivery pipe 1, the purpose of adjusting the brine flow rate can be achieved, and the brine delivery pipe 1 can also be completely closed. When the pushing wheel 22 releases the brine delivery pipe 1, the brine flow rate in the brine delivery pipe 1 reaches the maximum. The pushing wheel 22 partially extends out of the notch to facilitate pushing the pushing wheel 22.

[0032] The fixing member 4 is a cylindrical structure, and a through hole 42 is formed on the fixing member 4, which passes through both ends of the fixing member 4 in the axial direction. The saline delivery tube 1 passes through the through hole 42 and is tightly matched with the through hole 42. The C-shaped clamping cavity 41 also passes through both ends of the fixing member 4 in the axial direction and passes through the side of the fixing member 4. The inner wall surface of the C-shaped clamping cavity 41 protrudes to form evenly distributed protrusions 411, which can increase the firmness of the fixing member 4 on the milling cutter handle.

[0033] The upper end of the saline delivery tube 1 is connected with a dropper 5 whose inner diameter is larger than the inner channel diameter of the saline delivery tube 1, and the upper end of the dropper 5 is connected with the sharp puncture part 3. The dropper 5 is convenient for observing the flow rate of the saline.

[0034] The water outlet end of the salt water delivery pipe 1 is provided with an inclined surface 6 near the milling cutter handle 200 and the milling cutter 300, and the water outlet hole at the water outlet end is opened at the inclined surface 6, so that salt water can be sprayed toward the milling cutter 300 for flushing.

[0035] When in use, the sharp puncture portion 3 is inserted into the joint of the saline bag 100, the milling cutter handle is clamped in the C-shaped clamping cavity 41, the water outlet end of the saline delivery tube 1 is close to the milling cutter 300 installed on the milling cutter handle 200, the saline bag is hung, the pushing wheel 22 is operated to keep the saline delivery tube 1 in a smooth state and the position of the pushing wheel 22 is adjusted, so that the saline at the water outlet end of the saline delivery tube 1 can be used to flush the milling cutter with saline at a suitable flow rate to cool the milling cutter, effectively preventing the milling cutter from breaking due to high temperature during use, and the saline can also flush the skull bone chips milled off, without the need for multiple people to cooperate in the operation, and without frequent flushing and frequent transfer, which effectively improves efficiency and greatly shortens the operation. Since the fixing member 4 can be movable on the saline delivery tube 1, the relative position of the water outlet end of the saline delivery tube 1 and the position of the milling cutter on the milling cutter handle can be adjusted to accurately flush the milling cutter.

The saline delivery tube 1 passes through the C-shaped clamping hole 43 and the saline delivery tube 1 is tightly fitted with the C-shaped clamping hole 43. The design of the C-shaped clamping hole 43 facilitates the saline delivery tube 1 to be installed into the C-shaped clamping hole 43 from the side surface of the fixing member 4.

[0037] In other embodiments, Figure 7-8 The inner wall of the C-shaped card cavity 41 is fixed with a magnetic sheet 412, which can be firmly attached to the surface of the metal milling cutter handle. There are multiple magnetic sheets 412, which are alternately staggered on the two opposite side walls of the C-shaped card cavity 41, which can not only improve the firmness of fixing the milling cutter handle, but also make it easy to remove the milling cutter handle.
