Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a verticality indicator device for a surgical drill and the drill itself. Background Technology

[0002] In current surgical procedures, surgical drills are commonly used instruments, widely applied in orthopedics, neurosurgery, and other fields. During procedures involving vertical grooves in bone tissue, surgeons need to precisely control the drill's verticality to prevent tilting of the grooves, ensuring the safety and accuracy of the surgery.

[0003] However, existing surgical drill handles have the following technical drawbacks: 1. Difficulty in judging verticality: Traditional surgical drill handles lack effective verticality indicators, forcing surgeons to rely solely on experience and visual observation to determine the drill's verticality. This method is highly subjective and prone to error, especially in complex surgical environments such as bleeding or tissue obstruction, making accurate judgment even more challenging. 2. Insufficient operational precision: Due to the lack of real-time verticality feedback, surgeons are prone to fatigue during prolonged surgeries, leading to decreased operational precision. This is particularly true in critical surgical procedures requiring precise control of drill verticality, such as pedicle screw implantation in spinal surgery and cranioplasty, where even minor angular deviations can lead to serious complications. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a verticality indicator device and a drill for a surgical drill, which can observe the verticality status of the drill handle in real time and help doctors accurately control the surgical angle.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: In a first aspect, this utility model discloses a verticality indicator device for a surgical drill. The surgical drill includes a drill handle, and the verticality indicator device includes a bracket and a sealed cavity. The bracket includes a first fixing structure, and the bracket is detachably and arbitrarily circumferentially adjustable on the drill handle via the first fixing structure. The sealed cavity is disposed on the bracket. The sealed cavity contains liquid with an indicator bubble inside. The axial direction of the sealed cavity is installed perpendicular to the axial direction of the drill handle. When the drill handle is vertical, the indicator bubble is located in the exact center of the sealed cavity.

[0006] Furthermore, the first fixing structure is a C-shaped structure with elastic deformation capability. This design allows the first fixing structure to be directly snapped onto the drill handle, making disassembly and installation more convenient, and it can be adjusted arbitrarily on the drill handle.

[0007] Furthermore, the first fixing structure is an environmentally friendly plastic component, and the material thickness of the first fixing structure is 2.5-3.5mm. The first fixing structure is made of environmentally friendly plastic, which can be thermoplastic polyurethane (TPU), styrene-based thermoplastic elastomer (TPE-S), or modified polypropylene (PP). These materials have elastic deformation capabilities and can withstand high-temperature sterilization treatment.

[0008] Furthermore, the sealed cavity tube has an arc-shaped structure. When the support is mounted on the drill handle and the drill handle is in a vertical position, the outer side of the arc-shaped surface of the sealed cavity tube faces upward. Clinically, slight tilting is generally permissible, in which case the indicator bubble does not need to be as sensitive. Thus, when the upward-curved water-sealed cavity tube shifts laterally, the internal indicator bubble will slowly stop at the arc surface along the angle of shift, resulting in lower indicator bubble sensitivity and preventing the indicator bubble from deviating during slight tilting.

[0009] Furthermore, the bracket also includes a second fixing mechanism, on which the sealed cavity tube is detachably mounted. The sealed cavity tube can be integral with the bracket, or it can be detachably mounted on the bracket via the second fixing mechanism.

[0010] Furthermore, the second fixing structure is an arc-shaped structure that matches the sealed cavity tube. This configuration in the technical solution facilitates the installation of the arc-shaped sealed cavity tube using the second fixing structure.

[0011] Furthermore, the second fixing structure has several angle scale lines on the same side of the sealed cavity. The angle scale lines make it easier for medical personnel to read the deflection angle.

[0012] Furthermore, the stent also includes a connecting portion, which is disposed on the C-shaped back of the first fixing structure, and the second fixing structure is disposed on the connecting portion. This arrangement facilitates the doctor's observation of the indicator bubble inside the sealed cavity fixed on the second fixing structure; and the connecting portion, the first fixing structure, and the second fixing structure can be made of the same material and integrally injection molded during production.

[0013] Furthermore, the sealed cavity tube is detachably connected to the support. This allows the support and sealed cavity tube to be manufactured separately as individual parts and then assembled at the factory, or assembled only during use.

[0014] Furthermore, the second fixing structure is provided with a mounting groove, in which the sealed cavity tube is detachably engaged. This allows for more convenient detachable installation of the sealed cavity tube and the support.

[0015] Secondly, this utility model also discloses a grinding drill, which includes a grinding drill handle and the aforementioned verticality indicator device, wherein the verticality indicator device is detachably connected to the grinding drill handle via a first fixing structure.

[0016] The beneficial effects of this utility model are: 1. The verticality indicator device of the surgical drill of this utility model can detect when the drill handle is tilted during surgery. The indicator bubble in the sealed cavity will move from the center position to the opposite direction of the tilt, thereby identifying that the surgical drill handle has tilted at an angle. This allows the doctor to make timely adjustments and provides very intuitive and real-time feedback on the verticality of the drill. Therefore, this utility model can observe the verticality of the drill handle in real time, helping the doctor to accurately control the surgical angle.

[0017] 2. The verticality indicator device of the surgical drill of this utility model has a simple structure, low cost, and is easy to disassemble or install. It does not require modification of the existing drill handle, and is lightweight, so it does not affect the surgical operation.

[0018] 3. The verticality indicator device for a surgical drill of this utility model is made of environmentally friendly plastic and can withstand high temperature and high pressure sterilization.

[0019] 4. The observation surface of the sealed cavity tube of this utility model is an upward arc-shaped surface. When there is a lateral shift, the internal indicator bubble will slowly stop on the arc surface along the shift angle, and the indicator bubble sensitivity is lower. Clinically, slight tilting is allowed, which can avoid the indicator bubble from being deflected when tilted slightly. Attached Figure Description

[0021] The components include a bracket 1, a connecting part 11, a first fixing structure 12, a second fixing structure 13, a scale line 14, a sealed cavity tube 2, and a grinding drill handle 3. Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings: Example

[0023] This embodiment is a verticality indicator device for a surgical drill, such as... Figures 1-3As shown, the surgical drill has a drill handle, and the verticality indicator includes a bracket and a sealed cavity. The bracket includes a first fixing structure and a second fixing structure. The first fixing structure is a C-shaped structure and has elastic deformation capability. Thus, the bracket can be detachably and arbitrarily adjusted on the drill handle through the first fixing structure. In other embodiments, the bracket can also be detachably connected to the drill handle by screws.

[0024] Specifically, the first fixing structure is an environmentally friendly plastic component with a material thickness of 2.5-3.5 mm, which is 3.0 mm in this embodiment. The bracket also includes a connecting part, which is located on the C-shaped back of the first fixing structure, and the second fixing structure is also located on the connecting part. With this configuration, the first fixing structure is made of environmentally friendly plastic, such as thermoplastic polyurethane (TPU), thermoplastic styrene-based elastomer (TPE-S), or modified polypropylene (PP), which have elastic deformation capabilities and can withstand high-temperature sterilization. In this embodiment, the connecting part and the second fixing mechanism can also be made of environmentally friendly plastic components and injection molded together with the first fixing mechanism; alternatively, they can be manufactured separately and then assembled.

[0025] The sealed chamber is mounted on the second fixed structure and contains liquid with an indicator bubble. The axial direction of the sealed chamber is perpendicular to the axial direction of the drill handle. When the drill handle is vertical, the indicator bubble is located in the center of the sealed chamber, similar to a bubble level. The sealed chamber has an arc-shaped structure. When the support is mounted on the drill handle and the handle is vertical, the outer side of the arc-shaped surface of the sealed chamber faces upwards. Thus, when the upward-curved water-sealed chamber shifts laterally, the indicator bubble inside will gradually stop at the arc surface along the angle of shift. This reduces the sensitivity of the indicator bubble and prevents it from deviating even with slight tilting.

[0026] To match the arc-shaped sealed lumen tube, the second fixing structure in this embodiment is also configured as an arc-shaped structure matching the sealed lumen tube. Several angle scale lines are provided on the second fixing structure on the same side of the sealed lumen tube. The sealed lumen tube and the support are detachably connected. Specifically, the second fixing structure is provided with an installation groove, in which the sealed lumen tube is detachably secured. This configuration facilitates the installation of the arc-shaped sealed lumen tube using the second fixing structure; the angle scale lines also facilitate the reading of the deflection angle by medical personnel. Example

[0027] This embodiment is a drill, which includes a drill handle and the aforementioned verticality indicator device. The verticality indicator device is detachably connected to the drill handle via a first fixing structure.

[0028] The verticality indicator of the surgical drill of this utility model can be fixed on the drill handle of the surgical drill by the first fixing mechanism before the operation, so that when the drill handle is in the vertical state, the outer side of the arc-shaped surface of the sealed cavity is facing upward.

[0029] During surgery, when the drill handle tilts, the indicator bubble in the sealed cavity will move from the center to the opposite direction of the tilt, thus identifying that the drill handle has tilted at an angle, so that the doctor can make timely adjustments. It is very intuitive to use, providing real-time feedback on the verticality of the drill, and the approximate deflection angle can be understood through the scale lines, helping the doctor to control the surgical angle.

[0030] Because the observation surface of the closed cavity is an upward-facing arc, when there is a lateral shift, the internal indicator bubble will slowly stop on the arc along the shift angle, resulting in lower indicator bubble sensitivity. Clinically, slight tilting is allowed to avoid indicator bubble offset during slight tilting.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
