Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a power-driven handle. Background Art

[0002] In orthopedic surgery, bone tissue often needs to be ground. Manual operation is difficult to control the grinding force and is inconvenient. Therefore, a motor is usually used to drive the tool to grind the bone tissue and remove excess bone. However, the motor will continuously generate heat during the grinding process and conduct it to the handle. When used for a long time, the temperature of the handle will be too high, affecting the doctor's surgical operation and bringing additional risks to the operation. It will also cause the motor to overheat and even burn out. Among them, the interior of a general handle is also susceptible to moisture in the air and water ingress due to improper human operation, causing rust inside the motor to affect the motor function and reduce the service life of the handle. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a power-driven handle that can dissipate heat and reduce temperature in a timely manner.

[0004] The technical solutions of the present invention are as follows:

A cable connected to the stator 51 is inserted into the positioning hole 31, and one end of the oil filling pipe 4 passes through the wiring hole 13 and is sleeved in the fixing hole 32.

[0025] A mounting hole 33 is provided on the cable sheath 3 at a position corresponding to the water inlet hole 12 . A water injection pipe 331 is sleeved in the mounting hole 33 , and the sleeved end of the water injection pipe 331 extends into the water inlet hole 12 .

[0026] The inner wall of the wire protection sleeve 3 is provided with a boss 33 along the circumferential direction, and a slot 14 is provided on the outer wall of the mounting sleeve 1 at a position corresponding to the boss 34. The wire protection sleeve 3 is sleeved on the mounting sleeve 1, and the boss 34 is fixedly engaged with the slot 14.

[0027] A spiral groove is axially provided on the outer wall of the mounting sleeve 1 , and a water hole 121 communicating with the water inlet 12 is provided at one end of the groove. The spiral groove and the inner wall of the outer sleeve 11 form a spiral water channel.

[0028] A transition hole 111 is provided at one end of the outer sleeve 11, and a stepped boss 22 extending into the transition hole 111 is provided at one end of the outer wall of the base 2. The horizontal section of the stepped boss 22 and the corresponding position of the inner wall of the outer sleeve 11 form a water-containing cavity 6 connected to the water channel. A water outlet trough 21 is provided on the vertical section of the stepped boss 22. The vertical section of the stepped boss 22 is sleeved in the transition hole 111, and the water outlet trough 21 is connected to the water-containing cavity 6.

[0029] A clearance hole 23 is provided on the base 2 , and the clearance hole 23 is connected to the gap between the stator 51 and the rotor 52 .

[0030] The method of use of the present invention is as follows:

[0031] like Figure 1 、 Figure 2 as well as Figures 6 to 8As shown, before use, the stator 51 of the motor is fixed in the mounting sleeve 1, wherein a rotor 52 is provided in the middle through hole of the stator 51, and the two ends of the rotor 52 are respectively sleeved on two bearings (not marked) embedded in the through hole. At the same time, a gap is provided between the outer wall of the rotor 52 and the inner wall of the through hole so that the lubricating oil can flow between the rotor 52 and other components, thereby playing a lubricating role and reducing the wear of the rotor 52; then, the oil filling pipe 4 is fixed to one end of the stator 51, and one end of the oil filling pipe 4 is connected to the through hole position of the stator 51, and the other end of the oil filling pipe 4 is sleeved in the fixing hole 32 of the wire protection sleeve 3, and a base 2 is provided at the other end of the stator 51, and the step boss of the base 2 extends into the transition hole 111 of the outer sleeve 11 and is fixedly connected to the other end of the stator 51, and the base 2 is provided with a base 2. The give-way hole 23 is also connected to the through-hole position of the stator 51. In this way, the lubricating oil flows into the bearing position through the oil filling pipe in the fixed hole, and then flows into the rotor position through the gap between the bearing projectiles. After the lubricating oil flows through the rotor, it flows out to the base 2 position through the projectile gap of the other end bearing, and finally flows out through the give-way hole 23. During the whole process, the cable sleeve is arranged on the positioning hole 31 on the wire protection sleeve 3 and is electrically connected to the stator 51. The lubricating oil flows directly to the rotor 52 position in the middle of the stator 51 through the oil filling pipe 4 in the oil inlet direction, and will not leak to the position outside the motor, that is, it will not flow onto the cable and the inner wall of the mounting sleeve 1. The oil outlet direction also flows directly into the connected give-way hole 23. During the maintenance process, no residual pollution will be caused to the outside of the motor and the inner wall of the mounting sleeve 1.

[0032] like Figures 2 to 6 As shown, when used in surgery, the surgical tool is connected to the clearance hole 23 on the base 2, and cooling water flows into the water inlet hole 12 through the water injection pipe 331, and flows into the water channel formed by the spiral groove and the inner wall of the outer sleeve 11 through the water hole 121. After passing through the water channel, the cooling water flows into the water containing cavity 6 and is discharged through the water outlet trough 21, thereby achieving heat dissipation and cooling of the mounting sleeve 1 and the outer sleeve 11 (the mounting sleeve 1 and the outer sleeve 11 are combined into a handle style).

[0033] It should be noted that in order to make full use of the cooling water, an adaptive tool connection device can also be set at the position of the base 2 to divert the cooling water from the water outlet 21 to the tool, which can simultaneously achieve the cooling effect on the tool and improve the surgical grinding effect of the tool.

[0034] In addition, the motor described in the present invention is a conventional motor used in this field. Conventional motors include a stator 51 and a rotor 52. When the stator 51 is energized, the rotor 52 will rotate under the action of electromagnetic force. Therefore, there is a gap between the stator 51 and the rotor 52. This embodiment only records the connection between the stator 51 and the cable in the motor, and records the power source of the motor. At the same time, it is explained that there is a gap setting to allow lubricating oil to flow out of the motor and the mounting sleeve 1, and lubricating oil is only used during maintenance. When injecting lubricating oil, the handle is placed vertically so that the lubricating oil can fully flow out before use, and will not cause excessive residue and affect the safety of use. Those skilled in the art can master the operation.
