Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a bone drill which is convenient for heat dissipation. Background Art

[0002] A bone drill is a medical device commonly used in orthopedic surgery and other medical procedures that require operations on bones. The bone drill is rotated by electric or manual drive to perform operations such as drilling and expanding holes in bones.

[0003] However, bone chips will be generated during drilling and other work. If they cannot be quickly discharged, they will easily stick to the surface of the bone drill, thus affecting the smooth progress of the drilling work. In addition, due to the friction between the bone drill and the bone, especially when using an electric bone drill, the rapid friction between the bone drill and the bone will generate excessive heat, which may cause secondary injuries such as burns or even necrosis to the surrounding tissues. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a bone drill that is easy to dissipate heat, thereby solving the problems existing in the use of existing bone drills.

[0005] Technical solution: The utility model provides a bone drill that is easy to dissipate heat, including a knife body and a knife handle; the knife body is provided with four chip removal grooves arranged in a circular array with the center of the knife body as the axis, one end of the chip removal groove starts from the end of the knife tip of the knife body, and the other end of at least one chip removal groove extends to the end of the knife rod of the knife body. Four chip removal grooves are arranged on the knife body of the bone drill, so that the bone drill can remove chips in time during use, prevent bone chips from sticking, and dissipate heat well, thereby not only improving the accuracy of drilling and ensuring the smooth progress of the operation, but also reducing damage to the bone drill and increasing its service life. Adding a chip removal groove at the tip of the knife body greatly increases the sharpness of the bone drill and improves the drilling accuracy. In addition, at least one of the chip removal grooves is opened from the tip of the knife to the end of the knife handle, so that the chips and coolant can be better discharged and dissipated.

[0006] Furthermore, the tip of the knife body is conical, so that the bone drill can be positioned more accurately when drilling.

[0007] Furthermore, a back angle is provided on the back of the knife body, thereby improving the accuracy and sharpness of the bone drill during use.

[0008] Furthermore, the back angle is between 15° and 25°.

[0009] Furthermore, the surface of the cutter body is provided with a titanium oxide coating, which increases the strength of the cutter body surface, thereby greatly reducing the wear of the surface during the drilling process and increasing the service life.

[0010] Furthermore, the bone drill also includes a center hole, which passes through the tool body and the tool handle. A through center hole is opened in the middle of the bone drill to allow the coolant to reach the cutting part better and fully cool it.

[0011] Furthermore, a bone drill is provided, which adopts the bone drill described in any one of the above technical solutions.

[0012] It can be seen from the above technical scheme that the utility model has the following beneficial effects: 1) a chip removal groove is arranged on the cutter body of the bone drill, so that the bone drill can remove chips and dissipate heat in time during use, which not only improves the service life of the bone drill, but also improves the accuracy of drilling; 2) the tip position of the cutter body is set in a conical shape, thereby improving the positioning accuracy of the bone drill and improving the drilling accuracy. In addition, the chip removal groove is set starting from the tip position, which reduces the friction between bone chips and the bone drill in the human body, further improving the heat dissipation capacity and drilling accuracy; 3) a center hole is set that runs through the cutter body and the handle, so that the coolant can better reach the cutting part, greatly improving the heat dissipation capacity, thereby ensuring the normal progress of the operation and effectively reducing medical accidents caused by bone drill problems.
