Description

Technical Field

[0001] The utility model relates to the technical field of a driving structure for intraosseous infusion, in particular to an electric gun drill for intraosseous infusion. Background Art

[0002] Gun drill equipment developed for intraosseous infusion is typically used in conjunction with a disposable bone marrow puncture needle for intraosseous infusion. A disposable bone marrow puncture needle typically consists of a needle tube and a core needle. The base of the needle is secured to the drill head, and the needle is then inserted through the subcutaneous tissue. Once contact is made with the bone, the drill trigger is pressed and light pressure is applied to drive the needle into the bone. Once the needle reaches the bone marrow cavity, the core needle is removed, creating a channel to the tibia or humerus. Other medical devices can then be connected to the external needle holder for medication or infusion.

[0003] Existing gun drills have numerous internal components and utilize multiple chips for control and drive, resulting in a complex product structure and high production costs. Furthermore, existing gun drills lack low-battery warnings, which can lead to low-battery conditions during use, making them less safe. Furthermore, during installation, the puncture needle is inserted into the drive end, making it prone to falling off. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1 to 2 The figure shows an electric drill 10 for intraosseous infusion according to the present embodiment. The drill comprises a housing having a mounting portion 11 and a handle portion 12. The drive assembly is mounted on the mounting portion 11, and the handle portion 12 is designed to be held by a user for electric drilling operation. A drive motor 13 is mounted along a first straight line within the mounting portion 11. A reducer 15 is mounted at the end of the drive motor 13. A drive member 16 is fixed to the output end of the reducer 15. The drive member 16 is rotatably supported at a mounting end 111 of the mounting portion 11. A puncture needle 22 is mounted on the drive member 16. When the drive motor 13 is activated, the drive member 16 drives the puncture needle 22 to rotate and drill into the bone. A circuit board 17 and a control switch 18 are also mounted within the mounting portion 11. The control switch 18 has its two ends electrically connected to the drive motor 13 and the circuit board 17, respectively. The circuit board 17 and the control switch 18 control the drive motor 13, thereby controlling the rotational drilling operation of the puncture needle 22. This results in a simple electrical control structure and easy installation and operation. Inside the handle 12, a battery 19 is installed along the second straight line to provide power. The battery 19 is electrically connected to the circuit board 17. The bottom of the handle 12 is flat, allowing the intraosseous infusion electric gun drill 10 to be placed upright on a flat surface. This prevents the drive element 16 from contacting other objects and becoming contaminated when not in use. The angle between the first and second straight lines is designed to be 120 degrees, which improves the stability of the intraosseous infusion electric gun drill 10 when standing upright.

[0025] The circuit board 17 is snapped into the mounting portion 11 through the slot 114 provided in the mounting portion 11 , and the mounting surface of the circuit board 17 is arranged parallel to the drive motor 13 , resulting in a simple mounting structure and easy assembly and disassembly.

[0026] Based on the above structure, the mounting portion 11 is provided with an indicator light 20 at one end away from the driving member 16. The indicator light 20 is electrically connected to the circuit board 17 to display the power level of the battery 19. When the indicator light 20 lights up in a warning color, the device should be stopped from being used, providing intuitive risk control.

[0027] The housing is provided with a charging interface, which is electrically connected to the battery 19 . An external power source can be plugged in through the charging interface to charge the battery 19 .

[0028] The housing includes a first housing 23 and a second housing 24 , which are connected into a whole by welding, so that the sealing performance is good and the connection structure is more firm.

[0029] Furthermore, an adsorption magnet 21 is provided at one end of the driving member 16 for inserting the puncture needle 22. The adsorption magnet 21 can adsorb the iron sheet or magnet provided on the base of the puncture needle 22, so that the bone marrow puncture needle 22 can be adsorbed on the driving end of the gun drill and is not easy to fall off, thereby reducing the risk of the bone marrow puncture needle 22 falling during the process.

[0030] As a further structure, the outer shell of the drive motor 13 is formed with a positioning hole 131, and the inner wall of the mounting portion 11 is provided with a positioning piece for cooperating with the positioning hole 131, so as to install and position the drive motor 13, thereby improving the installation accuracy of the drive components and improving the installation efficiency.

[0031] Furthermore, a mounting protrusion 132 is formed on the end of the housing of the drive motor 13 away from the reducer 15. A mounting groove 112 is formed in the mounting portion 11 to cooperate with the mounting protrusion 132, thereby limiting the circumferential position of the mounting end 111 of the drive motor 13, thereby improving the installation accuracy and stability of the mounting structure. The mounting protrusion 132 and the mounting groove 112 are formed together, and the wire hole 14 can be used to lead the wiring of the drive motor 13, thereby ensuring the stability of the wiring lead of the drive motor 13 and making the electrical connection structure more reliable.

[0032] As a specific embodiment, the end of the driving member 16 for inserting the puncture needle 22 is a polygonal structure. By adapting the polygonal structure to the polygonal mounting hole of the puncture needle 22, the driving torque of the puncture needle 22 can be increased, thereby ensuring the rotational drilling effect of the puncture needle 22.

[0033] As a specific embodiment, the lower end of the handle 12 is formed with an oblique support leg 121 in the circumferential direction. The oblique support leg 121 can vertically and stably support the intraosseous infusion electric gun drill 10. The inclination of the oblique support leg 121 relative to the second straight line is designed to be 30 degrees, further improving the support stability of the intraosseous infusion electric gun drill 10.

[0034] As a specific embodiment, the mounting portion 11 is provided with first limiting ribs 113 around the outer periphery of the reducer 15 and drive motor 13. These ribs 113 define the mounting position of the reducer 15 and drive motor 13 to ensure accurate installation. The handle 12 is provided with second limiting ribs 122 around the outer periphery of the battery 19 to prevent the battery 19 from moving. This design further improves the precision and stability of the internal component mounting structure, while also preventing component misalignment from affecting the upright position of the intraosseous infusion electric gun drill 10, ensuring stable standing during use.

[0035] As a specific embodiment, the cross section of the hand-held portion 12 is elliptical, and a gripping recess 123 is formed on one side for the fingers to surround, so as to improve the hand-held comfort and prevent the intraosseous infusion electric gun drill 10 from slipping.

[0036] The internal structure of the aforementioned electric gun drill for intraosseous infusion 10 is linearly installed in the direction of the first straight line and the direction of the second straight line, resulting in high installation precision. The electrical components are linearly distributed and then uniformly controlled by a circuit board 17. The internal circuit structure is simple and the production cost is low. At the same time, the electric gun drill for intraosseous infusion 10 provides a low-battery warning via an indicator light 20. Thus, if a low-battery condition occurs during use, a prompt will be given, preventing low-battery operation and providing increased safety. Furthermore, the electric gun drill for intraosseous infusion 10 is designed with an adsorption magnet 21 at the end of the drive member 16. When the drive member 16 is engaged with the bone marrow puncture needle 22, the magnet can attract the iron sheet or magnet on the needle core base, allowing the bone marrow needle to be attracted to the end of the electric gun drill's drive member 16, preventing it from falling off, thereby reducing the risk of the bone marrow needle falling during operation. Such an electric gun drill for intraosseous infusion 10 is more convenient to operate and use.

[0037] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
