Description

Technical Field

[0001] This utility model relates to the field of bone drill technology, specifically a bone drill with an adjustment function. Background Technology

[0002] A bone drill is an electrically powered surgical instrument used to drill holes in bones. It is mainly used in orthopedic surgery. The bone drill uses a rotating drill bit to pass through bones, drill holes, or cut bones, helping doctors to complete orthopedic surgery efficiently and precisely control the drilling depth and angle to reduce surgical time and risks.

[0003] For example, the Chinese authorized patent (wear-resistant bone drill) with announcement number CN209826866U includes a drill tip, on the outer surface of which two or more tooth-shaped protrusions are raised. These protrusions are made of diamond. Therefore, by raising multiple tooth-shaped protrusions on the outer surface of the drill tip, this utility model makes the bone drill a toothed drill, thereby increasing the contact area and friction between the bone drill and the patient's bone. This increases the drilling speed and efficiency of the bone drill, shortens the operation time, and reduces the patient's suffering. At the same time, the tooth-shaped protrusions prevent the bone drill from slipping during drilling, ensuring the accuracy of the drilling. In addition, the diamond-shaped protrusions increase the strength and hardness of the protrusions, slowing down the wear rate of the protrusions and the bone drill during drilling, thereby enhancing the wear resistance of the bone drill and increasing its service life.

[0004] However, the bone drill in the prior art lacks an adjustable device, making it impossible to adjust according to the drilling position during use, which affects its ease of use and comfort. Therefore, it does not meet the current needs, and we propose a bone drill with an adjustable function. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable bone drill to solve the problem mentioned in the background art that the existing bone drill structure lacks an adjustable device, thus making it impossible to adjust according to the drilling position during use, which affects its convenience and comfort.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bone drill with an adjustable function, including a handle, an adjusting seat below the handle, a fixed seat between the handle and the adjusting seat, a fixed rod through which a fixed rod is installed, a drill rod above the handle, an adjusting rod on the upper surface of the adjusting seat, a limiting shaft inside the connection between the handle and the drill rod, and a rotating frame on both the upper and lower end faces of the limiting shaft.

[0007] Preferably, the surface of the limiting shaft is provided with a limiting rod, the rotating frame is rotatably connected to the limiting shaft, and the adjusting rod is provided with a fixing hole through it.

[0008] Preferably, a base is provided below the adjustment seat, and an energy storage tank is provided inside the base.

[0009] Preferably, anti-slip pads are installed on both the front and rear ends of the handle, and a drive mechanism is provided on one end face of the drill rod.

[0010] Preferably, a pressing rod is provided on one end face of the handle, and a pressing head is provided on one end face of the pressing rod.

[0011] Preferably, a drive head is provided on the other end face of the drill rod, the drive head is rotatably connected to one end face of the drill rod, a drill bit is installed on one side of the drive head, and one side of the drill bit is inserted into the drive head.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features an adjustment seat, which is connected to the handle via an adjustment rod. The fixed rod on the fixed seat is then threadedly connected to the fixing hole on the adjustment rod, thus providing adjustment and fixation. Simultaneously, a limiting shaft is installed between the handle and the drill rod. The rotating brackets on the upper and lower ends of the limiting shaft are connected to the handle and the drill rod respectively, allowing for rotational adjustment at the connection point. This solves the problem in existing bone drills where the lack of an adjustable device prevents adjustment based on the drilling position, affecting ease of use and comfort.

[0014] 2. A base is set at the bottom of the handle, with a battery storage tank inside for placing the battery. The base also serves as a support, allowing the drill bit to be placed directly on the table after use, preventing contamination. Anti-slip pads are also provided on the front and rear ends of the handle to ensure stability when holding it. Attached Figure Description
