Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a dual-plane transmissive medical X-ray power drill with variable direction. Background Technology

[0002] Surgical drills are commonly used tools in surgical procedures, particularly in orthopedic surgery for precise drilling and positioning. High precision in drill bit positioning and drilling direction is crucial during surgery, directly impacting the success or failure of the operation. This is especially true for procedures requiring precise positioning and drilling under fluoroscopy (such as the widely performed preparation of distal locking holes for intramedullary nails in long bone fractures of the limbs, sacroiliac screw implantation in the pelvis, and the use of channel screws in acetabular fractures). In these cases, existing surgical drills are completely inadequate for clinical needs. This is because they are very similar to ordinary drills, particularly in their structure and operation. All components are on the same plane, meaning that the surgeon and drill completely block the X-ray fluoroscopic image when aiming under fluoroscopy. Any deviation during drilling cannot be detected, and without real-time fluoroscopic imaging, precise drilling and hole opening are impossible. This leads to significant waste of surgical time and may even necessitate changes to the surgical plan due to excessive error, potentially resulting in unsuccessful surgery or even surgical failure.

[0003] Existing medical surgical drills mainly consist of a drill bit, a chuck, and a power output device. When using these drills for the aforementioned surgical procedures, the aforementioned defects have been observed:

[0004] Because the drill bit, the drill body power unit, and the surgeon are all on the same plane and axis during operation, all currently used surgical drills in clinical practice will block the penetration of X-rays during fluoroscopy, making it impossible to obtain accurate real-time fluoroscopic images during the operation. In order to achieve the surgical goal, the operation consumes a lot of time to repeatedly confirm the fluoroscopy from different angles. Moreover, during the drilling process, the positioning point may shift and the direction of the bone tunnel may deviate, which may lead to unsuccessful operation or even surgical failure. Utility Model Content

[0005] In view of the problems existing in the prior art mentioned in the background, this utility model provides a medical surgical power drill with dual-plane transmissive X-ray direction variable. It realizes the conversion of power on two different planes through a variable gear combination, thereby enabling operation on two different planes. It uses some X-ray-transmissive polymer material components to achieve the purpose of dual-plane transmissive X-ray direction variable. It can realize real-time operation under intraoperative fluoroscopy, and there is no situation where the surgeon blocks the X-rays during the operation. It improves surgical precision, increases surgical time efficiency and surgical success rate.

[0006] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A dual-plane, X-ray-transmitting, variable-direction medical surgical power drill includes a surgical drill body, a drill handle and a drill bit assembly mounted on the surgical drill body. The surgical drill body includes a first working plane assembly and a second working plane assembly connected by a variable-direction gear assembly. The power of the first working plane assembly is transmitted to the second working plane assembly after being redirected by the gear assembly. Then, the second working plane assembly is rotated to the desired direction and locked. After locking, the power is transmitted to the drill bit for drilling, realizing operation on both planes.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0016] (1) This utility model achieves the conversion of power from the first operating plane to the second operating plane by designing a 90-degree variable gear combination between the first power transmission shaft and the second power transmission shaft, so that the surgical power drill of this utility model can operate on both planes.

[0017] (2) The present invention achieves variable direction of the second power transmission shaft by rotating between the first and second planar drill bodies via an annular track; at the same time, a locking buckle is set on the annular track, and once the second power transmission shaft on the second planar drill body is adjusted to the required direction, the two planes are locked, thereby realizing stable output of power from the first power transmission shaft to the second power transmission shaft.

[0018] (3) When the X-ray passes parallel to the second power drive shaft of the second plane drill body, the X-ray can pass smoothly through the second power drive shaft on the second plane drill body by using a special high temperature, high pressure and wear resistant material (PPS) that can transmit X-rays, so that real-time fluoroscopy can be achieved during operation without the X-ray being blocked.

[0019] (4) Compared with the medical electric drill in the prior art, the power drill of this utility model realizes the conversion of power on two different planes through a variable gear combination, thereby realizing operation on two different planes.

Detailed Implementation

[0028] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] like Figure 1-7 As shown, the dual-plane transmissive medical X-ray variable-direction power drill provided in this embodiment mainly includes a surgical drill body, an electric drill handle 3, and a drill bit assembly; the surgical drill body includes a first working plane assembly and a second working plane assembly; the first working plane assembly is connected to the second working plane assembly; the electric drill handle 3 is connected to the first working plane assembly; and the drill bit assembly is connected to the second working plane assembly.

[0030] like Figure 1 As shown, the first working plane assembly includes a first plane drill body 1, a first power transmission shaft 14, and a first power motor; the first power transmission shaft 14 and the first power motor are both placed inside the first plane drill body 1. The second working plane assembly includes a second plane drill body 7, a second power transmission shaft 8, and a second power motor; the second power transmission shaft 8 and the second power motor are both placed inside the second plane drill body 7.

[0031] like Figure 1-5 As shown, in this embodiment, a set of 90-degree variable-direction gear combination is provided between the first power transmission shaft 14 and the second power transmission shaft 8. The gear combination is a bevel gear, including a driving gear 17 and a driven gear 18. The driving gear 17 is connected to the first power transmission shaft 14; the driven gear 18 is connected to the second power transmission shaft 8. This realizes the conversion of power from the first operating plane to the second operating plane, so that the surgical power drill of this embodiment can operate on both planes.

[0032] In this embodiment, both the driving gear 17 and the driven gear 18 are bevel gears; the meshing of the gears allows the rotation of the driving gear 17 to be transmitted to the driven gear 18, thereby realizing the transmission of mechanical motion.

[0033] An annular track is set between the first working plane assembly and the second working plane assembly. The rotation of the annular track enables the universal variable direction of the second power transmission shaft 8. At the same time, a locking buckle is set on the annular track. Once the second power transmission shaft 8 on the second plane drill body 7 is adjusted to the required direction, the locking buckle is used to lock the two planes, thereby realizing the stable output of power from the first power transmission shaft 14 to the second power transmission shaft 8.

[0034] like Figure 1-4 As shown, a drill bit assembly is connected to the output end of the second power transmission shaft 8. The drill bit assembly includes a chuck 9, an adjusting sleeve 10, an adjusting gear 15, a jaw 11, and a drill bit 12. The chuck 9 is connected to the second power transmission shaft 8. The adjusting sleeve 10 is sleeved on the chuck 9. An adjusting gear 15 is provided on the adjusting sleeve 10. The jaw is connected to the output end of the adjusting sleeve 10. The jaw 11 holds the drill bit 12.

[0035] The diameter of the adjusting sleeve 10 is changed by rotating the adjusting gear 15 through the adjusting gear wrench 13, which makes it easier to adjust the gripper 11 to hold drill bits 12 of different sizes.

[0036] The electric drill handle 3 is equipped with a power supply component. The electric drill handle 3 is equipped with a control button 2 for controlling the forward and reverse rotation and static neutral position of the motor, as well as a motor switch control button 4 and a ring track locking buckle unlocking button 5.

[0037] By pressing the motor switch control button 4, the first and second power motors are started. After the first power motor outputs power, it drives the first power transmission shaft 14 and the drive wheel 17 to rotate. The drive wheel 17 simultaneously drives the 90-degree driven wheel 18 to transmit power to the second power transmission shaft 8, realizing the change of power direction and converting the operating space into the second planar drill body 7. By pressing the ring track locking buckle unlock button 5 to unlock the ring track and locking buckle 6, the second planar drill body 7 can be controlled to rotate. The second planar drill body 7 rotates 360° along the ring track and locking buckle 6 along the first planar drill body 1. While the second power transmission shaft 8 rotates, it drives the chuck 9 to rotate as well. The jaws 11 clamp the drill bit 12 of a suitable diameter. The rotation of the drill bit 12 is controlled by activating the forward / reverse and static neutral control buttons 2.

[0038] The power supply component is a rechargeable battery. In this embodiment, the power supply component uses a removable rechargeable battery.

[0039] In this embodiment, the joints and gears of the connecting parts of the first and second operating planes are made of a special industrial plastic (PPS) that is resistant to high temperature, high pressure, and wear and is X-ray transparent, in order to achieve the purpose of a medical surgical drill with dual-plane variable X-ray transmission; so that X-rays can pass smoothly through the second power transmission shaft 8 on the second plane drill body 7, thereby realizing real-time fluoroscopy without causing X-ray obstruction.

[0040] The working principle or usage process of this utility model is as follows: First, the removable battery is inserted into the drill handle 3. After assembling the power drill, the ring track locking buckle unlock button 5 is pressed, and the operating space is converted into the second plane drill body 7. The second plane drill body 7 rotates 360° along the ring track and locking buckle 6, along the first plane drill body 1. When the second plane drill body 7 rotates to the required angle along the ratchet 16 on the ring track, the two planes are stably connected by two elastic limit buckles. The elastic limit buckles include elastic limit posts 19 and miniature springs 20 (e.g., Figure 6 , 7 (As shown); there are two small elastic limit posts 19 with miniature springs 20 below them. During rotation, the elastic limit posts 19 automatically reset through elastic force to form a limit in the opposite direction and form a tight engagement with the ratchet 16.

[0041] Then, using the adjusting gear wrench 13, the adjusting gear 15 is rotated to change the diameter of the adjusting sleeve 10. Finally, the appropriate diameter drill bit 12 is clamped by the chuck 11. Finally, the motor switch control button 4 is pressed to start the first power motor and the second power motor. After the first power motor outputs power, it drives the first power transmission shaft 14 and the far-end driving wheel 17 to rotate together. At the same time, it drives the 90-degree driven wheel 18 to rotate and transmits the power to the second power transmission shaft 8, realizing the change of power direction and converting the operating space into the second plane drill body 7. The second power transmission shaft 8 drives the chuck 9 to rotate together. The chuck 11 clamps the appropriate diameter drill bit 12. Then, the forward / reverse and static neutral control buttons 2 are pressed to control the rotation of the drill bit 12, thus starting drilling.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered as protection of the present utility model.
