Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a drive handle. Background Technology

[0002] In clinical practice, some medical devices require corresponding power-driven handles. For example, a surgical burr disclosed in application number 202321252145.1 and a cartilage scraper disclosed in application number 202322971188.1 both require corresponding drive handles. These drive handles not only need to provide power to these medical devices, but also need to provide tubing for injecting saline solution.

[0003] Currently, the drive handle used in this type of medical device is a power-driven handle disclosed in application number 202221691463.3. This handle contains a motor that provides power and a water injection channel. The rear end of the handle has a cable, a water inlet, and an oil inlet. The cable provides power to the motor; the water inlet can be connected to an external water injection pipe to provide saline solution to the water injection channel inside the handle; the oil inlet is connected to the rear end of the motor, through which lubricant can be injected into the motor.

[0004] In the existing drive handle, the oil inlet, cable, and water inlet are all located at the same end, and the oil inlet is always kept open. After the equipment is used, the water pipe needs to be disconnected from the water inlet, which means that any salt water leaking from the water inlet or pipe may enter the oil inlet and then the motor, causing internal rust and damage. Furthermore, when performing oiling maintenance on the motor, the water pipe needs to be removed and the cable bent, which is very inconvenient and reduces work efficiency. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a drive handle to solve the problem mentioned in the background art, in which the oil inlet is located between the cable and the water inlet in the existing drive handle, causing some salt water to enter the motor, resulting in rust and damage inside the motor.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A drive handle, the drive handle comprising:

[0008] The handle body has an oil injection hole on its side;

[0009] The motor is installed inside the handle body;

[0010] A cable protector is installed at one end of the handle body, and a cable for connecting the motor is installed on the cable protector.

[0011] Water injection connection pipe, which is installed on the protective sleeve;

[0012] The oiling component is installed inside the handle body and has an oiling channel that communicates with the oiling hole. An oiling pipe that communicates with the oiling channel is installed on the oiling component, and the end of the oiling pipe away from the oiling component is connected to the motor.

[0013] The oil injection component is equipped with a waterproof plug, an elastic element, and a plug within the oil injection channel; the waterproof plug is slidably installed within the oil injection channel to seal the oil injection channel; the plug is installed on the side of the oil injection channel away from the oil injection hole; and the elastic element is installed between the waterproof plug and the plug.

[0014] In one possible implementation, the waterproof plug includes a ball head, a connecting rod, and a sliding post; the ball head is located on the side near the oil injection hole; the sliding post is located on the side away from the oil injection hole and is slidably installed in the oil injection channel; the connecting rod is fixed between the ball head and the sliding post.

[0015] In one possible implementation, a connecting channel is provided on the side of the oil injection channel near the oil injection hole, and the diameter of the connecting channel is smaller than the diameter of the oil injection channel; the diameter of the ball head is between the diameter of the connecting channel and the diameter of the oil injection channel, and the ball head can block the connection between the connecting channel and the oil injection channel.

[0016] In one possible implementation, a connecting cap is provided at the end of the oil injection pipe away from the oil injection component, and the connecting cap is sealed to the oil inlet of the motor.

[0017] In one possible implementation, the handle body has a water injection channel, and the two ends of the water injection channel are respectively provided with a water inlet and a water outlet; one end of the water injection connecting pipe passes through the protective sleeve and is connected to the water inlet of the water injection channel.

[0018] In one possible implementation, the cable sheath is provided with a cable conduit, which is sleeved on the cable.

[0020] In one possible implementation, the end of the cable furthest from the motor is connected to a male connector.

[0021] The beneficial effects of this utility model are:

[0022] 1. By adopting the technical solution of this application, when the motor needs to be lubricated, lubricant can be injected into the lubrication channel of the lubrication component through the lubrication hole on the side of the handle body, and then injected into the motor through the lubrication pipe. This design separates the lubrication hole from the water injection connection pipe and cable, not only reducing the risk of saline solution entering the motor and causing rust and damage, but also ensuring that the lubrication operation is not interfered with by external water injection pipes and cables, thus improving the convenience of operation.

[0023] 2. By adopting the technical solution of this application, when no lubricant is injected, the waterproof plug can block the oil injection channel, play a role in sealing and waterproofing, and prevent external liquids from entering the motor, thereby improving safety; when lubricant is injected, the waterproof plug is subjected to the pressure of the lubricant and can move to the side of the compression elastic element, thereby unsealing the oil injection channel, allowing the lubricant to enter the oil injection pipe through the oil injection channel and finally enter the motor.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0030] like Figures 1-3 As shown, this application embodiment provides a drive handle, including a handle body 100, a motor 200, a cable sleeve 300, a water injection connection pipe 400, and an oil injection component 500. The handle body 100 has a cavity inside for mounting the motor 200 and the oil injection component 500, and an oil injection hole 110 is provided on the circumferential side of the handle body 100. The motor 200 is fixedly installed inside the handle body 100 and is used to provide power to other medical devices. The motor 200 can be a servo motor or a stepper motor. The cable sleeve 300 is installed at one end of the handle body 100, and a cable 600 connecting to the motor 200 is installed on the cable sleeve 300. The cable 600 passes through the cable sleeve 300 and provides power to the motor 200. The water injection connection pipe 400 is installed on the cable sleeve 300 and is used to connect to an external water injection pipe. The oil injection component 500 is installed inside the handle body 100 and is located between the tail of the motor 200 and the cable sleeve 300. The oiling component 500 has an oiling channel 510, one end of which is connected to the oiling hole 110. An oiling pipe 520 connected to the oiling channel 510 is installed on the oiling component 500, and the end of the oiling pipe 520 away from the oiling component 500 is connected to the motor 200.

[0031] With the above technical solution, when lubrication maintenance of the motor 200 is required, lubricant can be injected into the lubrication channel 510 of the lubrication component 500 through the lubrication hole 110 on the side of the handle body 100, and then injected into the motor 200 through the lubrication pipe 520. This arrangement separates the lubrication hole 110 from the water injection connection pipe 400 and the cable 600, reducing the risk of saline solution entering the motor 200 and causing rust and damage. It also ensures that the lubrication operation is not interfered with by the external water injection pipe and cable 600, improving operational convenience.

[0032] In one possible embodiment, the oil filling component 500 is equipped with a waterproof plug 530, an elastic element 540, and a plug 550 within the oil filling channel 510. The waterproof plug 530 is slidably installed within the oil filling channel 510 to seal it, preventing lubricant from entering the oil filling pipe 520 through the channel. The plug 550 is installed on the side of the oil filling channel 510 away from the oil filling hole 110, connecting to the elastic element 540 and sealing the end of the oil filling channel 510 away from the oil filling hole 110. The elastic element 540 is installed between the waterproof plug 530 and the plug 550. The elastic element 540 can be an elastic structure such as a coil spring, compression spring, or sheet spring; in this embodiment, a threaded spring is preferred. Both ends of the elastic element 540 are connected to the waterproof plug 530 and the plug 550, respectively. With this configuration, when no lubricant is being injected, the waterproof plug 530 can seal the oil injection channel 510, thus providing a waterproof seal and preventing external liquids from entering the motor 200, thereby improving safety. When lubricant is injected, the waterproof plug 530 is subjected to the pressure of the lubricant and can move to the side of the compression elastic element 540, thereby unsealing the oil injection channel 510 and allowing the lubricant to enter the oil injection pipe 520 through the oil injection channel 510, and finally enter the motor 200.

[0033] Specifically, the waterproof plug 530 includes a ball head 531, a connecting rod 532, and a sliding post 533. The ball head 531 is located on the side closest to the oil filling hole 110; the sliding post 533 is located on the side furthest from the oil filling hole 110 and is slidably installed within the oil filling channel 510; the connecting rod 532 is fixed between the ball head 531 and the sliding post 533. This arrangement allows the ball head 531 to block the oil filling channel 510, the sliding post 533 to move the waterproof plug 530, and the connecting rod 532 to connect the ball head 531 and the sliding post 533. These three components work together to achieve the function of the waterproof plug 530.

[0034] In one possible embodiment, a connecting channel 511 is provided on the side of the oil passage near the oil injection hole 110, and the diameter of the connecting channel 511 is smaller than the diameter of the oil injection passage 510. The diameter of the ball head 531 is between the diameter of the connecting channel 511 and the diameter of the oil injection passage 510, and the ball head 531 can block the connection between the connecting channel 511 and the oil injection passage 510. With this arrangement, the oil injection passage 510 can be blocked and unblocked.

[0035] In one possible embodiment, a connecting cap 521 is provided at the end of the oil injection pipe 520 away from the oil injection component 500. The connecting cap 521 is sealed to the oil inlet of the motor 200. By providing the connecting cap 521, the connection between the oil injection pipe 520 and the motor 200 can be highly sealed, reducing the risk of leakage.

[0036] In one possible embodiment, the handle body 100 has a water injection channel, with a water inlet and an outlet at each end. The implementation of the water injection channel is consistent with existing technology, as detailed in a power-driven handle disclosed in application number 202221691463.3, which will not be described in detail in this embodiment. One end of the water injection connecting pipe 400 passes through the cable sleeve 300 and communicates with the water inlet of the water injection channel. The other end of the water injection connecting pipe 400 is provided with an interface 410 for connecting to an external water injection pipe.

[0037] In one possible embodiment, a protective tube 310 is provided on the protective sleeve 300, and the protective tube 310 is sleeved on the cable 600 to enhance the protection performance of the cable 600.

[0038] In one possible embodiment, a plurality of brine clamps 610 are detachably mounted on the cable 600. By providing brine clamps 610, it is convenient to position the external water injection pipe connected to the water injection connection pipe 400, thereby enhancing convenience.

[0039] In one possible embodiment, the end of the cable 600 away from the motor 200 is connected to a male connector 620, which is connected to an external device or power source to provide power to the motor 200.

[0040] 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.
