Description

[0002] In actual surgical work, such as tibial drilling and drainage, drilling work is required, and the drilling quality is particularly important. The lesion needs to be removed through bone drilling. In actual drilling work, it is necessary to avoid expanding the damaged tissue. The current surgical drilling device is not easy to control to prevent excessive drilling pressure, which can easily cause damage to the drilling edge when breaking through the bone, and it is also easy to damage the muscle. However, too little downward pressure will affect the drilling efficiency, and it is not easy to automatically control to reduce the drilling pressure when the bone is almost drilled through. At the same time, it is not easy to prevent the bone marrow cavity from being damaged by flushing. In order to ensure the flushing effect, water pressure usually needs to be guaranteed. However, after drilling through the bone marrow cavity, water flushing is usually used for safe cleaning.

By using a water hole 2031 in conjunction with a side hole 2032, water can be easily circulated for flushing. The structure is more reasonable and can be used for cooling and flushing broken bones.

[0035] Among them, the lifting adapter 4 includes: a lifting sleeve 401, a threaded connection frame 4011, an upward spring 402 and a stopper electrical connection piece 403.

The propulsion member 5 is used in conjunction with the lifting adapter 4 to control the time for the elastic retraction intervention of the collapse limiter 3. When drilling into the bone in the early stage, it can ensure that the doctor can have good downward pressure, ensure the drilling efficiency, avoid long-term drilling, and improve the speed of the operation. At the same time, when the bone thickness is close to the bone thickness, the collapse limiter 3 is automatically controlled to be elastically retracted to ensure the safety of drilling when it is close to drilling through, and avoid the bone being pressed and broken. The structure is more reasonable, more in line with the actual surgical operation requirements, and the structure is simple to operate. You can first use surgical imaging equipment, such as an X-ray machine, to understand The thickness of the bone is adjusted by rotating the threaded column 502 to drive the retaining ring 501 to move, and the distance between the bottom of the retaining ring 501 and the bottom of the drill bit 203 is adjusted according to needs to ensure that the stop and electrical connection plate 403 no longer blocks the collapse shaft 301 before the drill bit 203 drills through the bone. As the downward pressure increases, the outer side of the bone will stop the retaining ring 501, and the retaining ring 501 cannot enter the drill hole together, which will push the lifting sleeve 401 to move upward, driving the stop and electrical connection plate 403 to no longer block the collapse shaft 301. At this time, it is also close to the distance for drilling through the bone. If the doctor still presses down hard, the collapse shaft 301 will automatically retract for protection.

[0036] Embodiment 2, on the basis of embodiment 1, the rotary sleeve 6 comprises: a pressure sleeve 601 and a water supply pipe 602, the pressure sleeve 601 is sleeved on the drill bit 203; the pressure sleeve 601 is located between the limit ring 2033 and the drilling column 201; the pressure sleeve 601 is aligned with the upper end of the water hole 2031; the pressure sleeve 601 is fixedly mounted with a water supply pipe 602; the water supply pipe 602 is connected to the inside of the pressure sleeve 601; a hand-held ring is provided on the water supply pipe 602; the hand-held ring on the water supply pipe 602 is used for hand-held ; The pressure sleeve 601 is connected to the water hole 2031; the rotary socket 6 also includes: a connecting pipe 603 and a solenoid valve 604, the connecting pipe 603 is fixedly installed on the water pipe 602; the connecting pipe 603 is externally connected to a water pump; the solenoid valve 604 is fixedly installed on the connecting pipe 603; the solenoid valve 604, the stopper electrical piece 403 and the contact piece 303 are connected in series with the battery power supply, and the rotary socket 6 can be used for auxiliary water supply for flushing and cooling work, and the water supply position is more direct, and can be directly Drainage at the bottom of the hole can improve the hole cleaning effect. At the same time, this structure can cooperate with the lifting adapter 4 to automatically control the water pressure to stop when it is close to the drilling position, so as to avoid the water pressure causing compression damage to the bone marrow cavity. It can be used to control protection when drilling is about to be penetrated to protect the intramedullary venous network. This structure can realize automatic control to avoid manual forgetfulness and is simple to operate. When the stop contact piece 403 stops the collapse shaft 301, that is, the early drilling work, the drilling pressure is large and the heat is large. When the bone is about to be drilled through, the stop contact piece 403 no longer blocks the collapse shaft 301, and the stop contact piece 403 no longer fits the contact piece 303. At this time, the solenoid valve 604 is closed to avoid continuous water spraying, which also reminds the staff that they are close to drilling through the bone and need to turn off the water pump outside the connecting pipe 603. A syringe can be used to assist in water injection and flushing to avoid the high flushing pressure causing compression damage to the intramedullary venous network, increase safety hazards, improve surgical protection effects, and be more suitable for tibial drilling and drainage.

[0037] The working principle of this embodiment is as follows: First, the handle 101 is pressed down by hand, and the sliding sleeve 103 is driven by the driving motor 102 to drive the drill bit 203 to drill into the bone to open a hole. When the handle 101 is pressed down, once the pressure is excessive, the arc structure at the end of the collapse shaft 301 slips out of the groove on the side of the drilling column 201, and the tension spring 302 can be stretched. When the downward pressure is small, the tension spring 302 can pull the collapse shaft 301 to be plugged into the drilling column 201 to ensure normal drilling. The water pump supplies physiological saline, which is introduced into the pressure sleeve 601 and then guided to the side hole 2032 for discharge for flushing. During the process, the doctor holds the hand ring provided on the water supply pipe 602 with one hand to help stabilize the drill bit 203. Under the pressure of the upward spring 402, the lifting sleeve 401 presses down to drive the stop contact piece 403 to stop the collapse shaft 301. At this time, the staff directly presses down the drill bit 203. Even if there is upward pressure on the drill bit 203, the collapse shaft 301 cannot retract. As the downward pressure increases, the drilling depth increases. , the bone will stop the retaining ring 501, push the lifting sleeve 401 to move up, and drive the stop electrical plate 403 to no longer block the collapse shaft 301. At this time, it is also close to the distance of drilling through the bone. If the doctor still presses down hard, the collapse shaft 301 will automatically retract for protection. Similarly, once the drilling depth is deep and close to drilling through the bone, the stop electrical plate 403 no longer blocks the collapse shaft 301, and the stop electrical plate 403 no longer fits the contact plate 303. At this time, the solenoid valve 604 is closed to avoid continuous water spraying, which is also a reminder to the staff. When drilling through the bone, it is necessary to turn off the water pump connected to the connecting tube 603. At this time, a syringe can be used to assist in water injection and flushing. A threaded connecting frame 4011 is rotated on the lifting sleeve 401. When the lifting sleeve 401 is driven to rotate by the driving motor 102, the threaded connecting frame 4011 is connected to the lifting sleeve 401 by rotation, and cooperates with the retaining ring 501 to be sleeved on the drill bit 203, which will not interfere with the rotation of the drill bit 203. At the same time, the threaded column 502 will not rotate together, avoiding jamming with the rotary sleeve 6.
