Technical Field

[0001] This utility model relates to the field of neurosurgical auxiliary equipment technology, specifically an automatic cooling device for medical instruments used in brain surgery. Background Technology

[0002] In neurosurgery, cranial drills and milling cutters are used during procedures. The milling cutter head and cranial drill head rotate at high speed to drill holes in the skull or grind away bone. However, the process of drilling or grinding the skull generates high temperatures that can burn brain tissue. Therefore, during surgery, it is necessary to continuously use saline solution to cool the skull and prevent the cranial drill from damaging the brain tissue.

[0003] However, existing automatic cooling devices for brain surgery have the following problems during use: During the cooling process, the saline solution needs to be held and fixed by the nurse for an extended period to facilitate dripping, making the cooling operation extremely labor-intensive. Therefore, a corresponding technical solution needs to be designed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cooling device for medical instruments used in brain surgery, which solves the technical problem that the cooling operation is very labor-intensive because the saline solution needs to be held and fixed by the nurse for a long time and pushed to drip during the cooling process, thus meeting the actual use needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a skull drill, a drill bit disposed between one end and the interior of the skull drill, a driving component disposed between the interior of the skull drill and the drill bit, a dropper disposed between the end of the skull drill (same as the drill bit) and the interior of the skull drill, an extension tube disposed between one end of the dropper and the skull drill, a drip tube inserted into one end of the dropper, a connecting liquid tube inserted into one end of the dropper located within the extension tube, a speed regulator installed on the connecting liquid tube, and a liquid supply component connected to the end of the connecting liquid tube.

[0006] In a preferred embodiment of this utility model, the outer edge of the skull drill has anti-slip texture, and one end of the drill bit is fixed to the driving end of the driving member.

[0007] In a preferred embodiment of this utility model, the end of the dropper connected to the drip tube is located outside the skull drill, one end of the dropper is fixed inside the extension tube, the drip tube is made of a deformable material, and a protective cap is installed on one end of the dropper.

[0008] In a preferred embodiment of this utility model, the extension tube is fixed to the skull drill in an inclined manner, and the skull drill is provided with a through hole for use with the extension tube, and the extension tube is connected to the through hole.

[0009] In a preferred embodiment of this utility model, an anti-slip block is movably connected to the outer edge of the skull drill, and there is damping between the anti-slip block and the skull drill. The speed regulator adopts a speed regulating structure with a roller structure on an infusion tube.

[0010] In a preferred embodiment of this utility model, the liquid supply device adopts either an infusion bag or a syringe, and the liquid supply device is filled with physiological saline.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By using components such as a fixing ring and a dropper, the dropper can be fixed close to the skull drill bit. During brain surgery, it is no longer necessary to manually hold and fix the dropper for a long time and push the saline solution to cool the skull drill bit and milling cutter head, which effectively saves manpower and solves the problem of the cooling operation being very labor-intensive.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: an automatic cooling device for a medical instrument used in brain surgery, comprising: a cranial drill 1, a drill bit 9 disposed between one end and the interior of the cranial drill 1, a drive unit 10 disposed between the interior of the cranial drill 1 and the drill bit 9, a dropper 7 disposed between the same end of the cranial drill 1 as the drill bit 9 and the interior, an extension tube 6 disposed between one end of the dropper 7 and the cranial drill 1, a drip tube 3 inserted into one end of the dropper 7, a connecting liquid tube 5 inserted into the end of the dropper 7 located inside the extension tube 6, a speed regulator 4 installed on the connecting liquid tube 5, and a liquid supply unit 2 connected to the end of the connecting liquid tube 5.

[0016] Further improvements include an anti-slip texture on the outer edge of the skull drill 1, and one end of the drill bit 9 is fixed to the drive end of the drive unit 10.

[0017] In a further improvement, the end of the dropper 7 connected to the drip tube 3 is located outside the skull drill 1, and the other end of the dropper 7 is fixed inside the extension tube 6. The drip tube 3 is made of a deformable material, and a protective cap 8 is installed on one end of the dropper 7.

[0018] In a further improvement, the extension tube 6 is fixed to the cranial drill 1 at an angle, and the cranial drill 1 is provided with a through hole for use with the extension tube 6, and the extension tube 6 is connected to the through hole.

[0019] Further improvements include a sliding block 11 movably connected to the outer edge of the skull drill 1, with damping between the sliding block 11 and the skull drill 1, and the speed regulator 4 adopting a speed regulating structure with a roller structure on the infusion tube.

[0020] Further improvements include the use of either an infusion bag or a syringe for the fluid supply device 2, which is filled with physiological saline.

[0021] In use: First, the liquid supply component 2 is connected to the connecting liquid pipe 5. The other end of the connecting liquid pipe 5 is inserted into the extension pipe 6. When the cranial drill 1 is in use, the liquid supply component 2 injects the internal physiological saline and finally flows out through the drip pipe 3 to cool the drill bit of the cranial drill 1. It does not require manual holding and fixing for a long time, thus ensuring the cooling effect.

[0022] The components of this invention, including the cranial drill-1, cranial drill-1, liquid supply component-2, drip tube-3, speed controller-4, connecting liquid tube-5, extension tube-6, drip tube-7, protective cap-8, drill bit-9, drive component-10, and protective block-11, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
