Description

Technical Field

[0001] The invention relates to the technical field of grinding drills, in particular to a grinding drill capable of preventing bone chips from splashing. Background Art

[0002] Brain surgery generally refers to neurosurgery, which is a discipline that utilizes neurosurgery, with examination as the main method, surgery as the path, comprehensive treatment, and comprehensive evaluation. The scope of neurosurgery research includes the causes and pathogenesis of diseases such as congenital developmental abnormalities of the nervous system, trauma, infection, tumors, vascular lesions, and genetic metabolic disorders, and explores new diagnostic and treatment methods.

[0003] Since there are many brain surgeries and most of them need to be performed on the patient's brain, brain surgeries often require the removal of the patient's skull flap, opening holes and windows, etc., to facilitate doctors to perform brain surgery through the skull.

[0004] When performing bone flap removal, opening holes and windows on the patient's skull, most of the time, devices such as milling cutters and grinding drills are needed to help doctors grind and perforate the skull. However, there are still certain problems in the actual use of milling cutters and grinding drills:

[0005] 1. When using a milling cutter and a bur to perform drilling and grinding operations on the skull, the milling cutter and the bur rotate at high speed, which makes it easy for friction and heat to occur at the contact point between the bur and the bone, affecting the safety of the patient. At the same time, when the bur is working, it is easy for bone chips to splash and fly around. In most of these cases, an assistant will spray water on the contact point between the bur and the bone and on the bur to keep the bur and the contact point moist to cool down and prevent bone chips from splashing. This manual spraying of water is not very practical and wastes labor;

[0006] 2. Most milling cutters and drills need to be driven by small motors. In order to facilitate the doctor's holding, most of them use cylindrical handles. In actual operation, the doctor's hands are easily contaminated with the patient's body fluids, causing slippery hands and unstable grip, which affects the doctor's use of the drill to drill and grind the skull. Summary of the invention

The other end of the regulating shaft 502 passes through the bottom wall of the basic gripping shell 1 and protrudes. The extrusion eccentric wheel 6 is arranged on the regulating shaft 502. When the rotating shaft 5 and the extrusion eccentric wheel 6 rotate and squeeze the extrusion ball sleeve 703 to squeeze out the water inside the water storage cylinder 702, the regulating shaft 502 can be pulled and pressed. The positions of the regulating shaft 502 and the extrusion eccentric wheel 6 at the ends of the base shaft 501 are adjusted, thereby adjusting the relative position of the extrusion eccentric wheel 6 and the outer arc surface of the extrusion ball sleeve 703. When the extrusion eccentric wheel 6 and the extrusion ball sleeve 703 are adjusted to no longer be extruded, the extrusion of the extrusion ball sleeve 703 can be interrupted, and the water discharge is stopped at this time. The closer the extrusion position of the extrusion eccentric wheel 6 and the extrusion ball sleeve 703 is, the greater the water discharge. By controlling the degree of extrusion of the extrusion eccentric wheel 6 on the extrusion ball sleeve 703, the amount of water inside the water storage cylinder 702 squeezed by the extrusion ball sleeve 703 is controlled, thereby controlling the water discharge of the water outlet hose 8.

[0036] In the present embodiment, when in use, the user holds the basic grip 2 and the basic grip shell 1, starts the driving motor 4, and uses the driving motor 4 to drive the rotating shaft 5 and the squeezing eccentric wheel 6 to rotate. At this time, the squeezing eccentric wheel 6 will squeeze the squeezing ball sleeve 703, and use the squeezing ball sleeve 703 to squeeze the water inside the water storage cylinder 702, so that the water is discharged through the water outlet hose 8. The other end of the water outlet hose 8 faces the grinding drill body 1302, and the water is sprayed on the grinding drill body 1302. When it is necessary to adjust the spraying position, the telescopic rod 301 can be pulled to adjust the position of the fixed pipe sleeve 302 and the end of the water outlet hose 8 facing the grinding drill body 1302, so as to adjust the water outlet point. When the driving motor 4 drives the rotating shaft 5 to rotate, the gear group 12 is linked to the gear group 12. The linkage effect will drive the linkage shaft 11 to rotate synchronously. At this time, the linkage shaft 11 will drive the mounting seat 1301 at the bottom and the drill body 1302 to rotate, and the drill body 1302 can be used to perform operations such as drilling and grinding on the patient's skull. During the process, the position of the regulating shaft 502 and the extrusion eccentric wheel 6 at the end of the basic shaft 501 can be controlled by pulling out and pressing the part of the regulating shaft 502 that passes through the bottom wall of the basic holding shell 1, thereby controlling the relative position and extrusion degree of the extrusion eccentric wheel 6 and the extrusion ball sleeve 703, thereby controlling the water output to stop and the water output.
