Description

Technical Field

[0001] The utility model relates to a medical device for intracranial hematoma puncture, in particular to an electric driver for intracranial hematoma puncture. Background Art

[0002] Due to hypertension, trauma and other reasons, when blood vessels in the brain or between the brain tissue and the skull rupture, blood accumulates in the brain or between the brain and the skull, and compresses the brain tissue, an intracranial hematoma is formed. Intracranial hemorrhage has an acute onset and is critical. After bleeding, the hematoma compresses the functional nuclei and sensory motor conduction bundles, leading to neurological dysfunctions such as coma and hemiplegia, with extremely high mortality and disability rates. At present, the treatment of intracranial hematoma is mainly based on craniotomy and hematoma puncture. When performing intracranial hematoma puncture treatment, the patient's intracranial hematoma is usually located based on CT first, and then artificial puncture and drainage are performed through perforation puncture. However, when performing perforation puncture, most of the operators hold the electric driver to operate the drill vertically to the brain, which depends on the user's clinical experience. If the drill is offset during the perforation puncture, it may cause the needle insertion direction of the puncture to be offset, the puncture is not accurate, and the surgical treatment effect is affected. Utility Model Content

[0003] In view of the above technical problems, the utility model provides an electric driver for intracranial hematoma puncture with relatively accurate hole puncture.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an electric driver for intracranial hematoma puncture, comprising a handle for hand holding and a driver body connected to the handle, a hole-opening puncture drill bit for intracranial hematoma puncture is installed at the front end of the body, a slot is horizontally opened at the rear end of the body, a bracket is arranged in the slot, a spirit level is installed on the bracket, and the spirit level is perpendicular to the axial direction of the hole-opening puncture drill bit.

[0005] Preferably, the slot is a horizontally arranged dovetail slot, the bracket comprises an insert plate which can be horizontally inserted into the dovetail slot from the side and a mounting plate connected to the insert plate, and the level is fastened to the mounting plate by screws.

[0006] Preferably, a support arm is provided on the insert plate along the axial direction of the hole-opening puncture drill bit, and one of the mounting plates is fixedly connected to the support arm.

[0007] Preferably, the upper portion of the mounting plate is inclined toward the side of the hole-opening piercing drill bit.

[0008] Preferably, when the inserting plate is inserted into the dovetail slot, the supporting arm extends out of the notch of the dovetail slot.

[0009] Preferably, a handle is provided at one end of the plug board.

[0010] Preferably, the insert plate is provided with at least one annular groove according to its cross-sectional profile, and a rubber ring is provided in each annular groove.

[0011] Preferably, the body includes a casing connected to the upper end of the handle and a gear assembly arranged in the casing, the front end of the gear assembly is provided with a drill clamp that can clamp the hole-opening and puncturing drill bit, and the rear end is provided with an electric motor, and the electric motor drives the hole-opening and puncturing drill bit to rotate through the gear assembly and the drill clamp.

[0012] Preferably, a speed regulator connected to the gear assembly is provided in the casing.

[0013] From the above technical scheme, it can be seen that the utility model is provided with a spirit level on the body. When the operator holds the driver to perform hole puncture, as long as the drill bit is offset, the spirit level will change to remind the operator to correct the hole opening position, so that the operator can accurately grasp the direction of hole puncture, making the insertion direction of the hematoma puncture needle easier to control, less likely to deviate, and more accurate puncture.

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides an electric driver for intracranial hematoma puncture, which includes a handle 1 for hand holding and a body 2 of the driver connected to the handle, a perforation puncture drill 3 for intracranial hematoma puncture is installed at the front end of the body, and a slot 26 is horizontally provided at the rear end of the body, a bracket 4 is provided in the slot, and a level 5 is installed on the bracket, and the level is perpendicular to the axial direction of the perforation puncture drill. During implementation, the level can be a simple bubble level or the like. When the operator holds the driver of the utility model vertically to the brain for perforation puncture, the level is perpendicular to the pre-set puncture path. As long as the drill bit deviates, the level will change and display the deviation direction, thereby reminding the operator to correct the perforation puncture direction and ensure that the perforation puncture is more accurate.

[0019] Preferably, the slot is a horizontally arranged dovetail slot, and the bracket 4 includes an insert plate 41 that can be horizontally inserted into the dovetail slot from the side and a mounting plate 42 connected to the insert plate, and the level is fastened to the mounting plate by screws. The design of the dovetail slot ensures that the disassembly and installation of the bracket are more convenient and quick, and realizes the detachable connection of the level, so that the level can be disassembled or installed according to needs. Specifically, a support arm 43 is provided on the insert plate along the axial direction of the perforating piercing drill bit, and each support arm is fixedly connected to the mounting plate, so that the level is fastened to the mounting plate to ensure the stable installation of the level.

[0020] The upper part of the mounting plate of the utility model is tilted toward the side of the perforating puncture drill bit, so that it is more convenient to install the spirit level, ensure a more stable installation, and make it easier for the operator to observe the spirit level. Preferably, when the plug plate is inserted into the dovetail groove, the support arm extends out of the notch of the dovetail groove to avoid interference and affect the installation of the spirit level. A handle 44 is provided at one end of the plug plate, which makes it easier to install and disassemble the bracket. During implementation, at least one annular groove 45 is provided on the plug plate according to its cross-sectional profile, and a rubber ring 46 is provided in each annular groove to ensure the tightness of the connection between the plug plate and the dovetail groove and prevent the plug plate from shaking or easily slipping from the dovetail groove.

[0021] During the implementation, the body 2 includes a housing 21 connected to the upper end of the handle and a gear assembly 22 disposed in the housing. The front end of the gear assembly is provided with a drill clamp 23 that can clamp the perforation puncture drill bit, and the rear end is provided with an electric motor 24. The electric motor drives the perforation puncture drill bit to rotate through the gear assembly and the drill clamp, thereby achieving perforation puncture and achieving the purpose of intracranial hematoma puncture treatment. Preferably, a speed regulator 25 connected to the gear assembly is provided in the housing 21. The speed regulator adjusts the speed by controlling the meshing state of different gears between the gears of the gear assembly. The structure and installation of the speed regulator achieve the purpose with the existing technology.
