Technical Field

[0001] The invention relates to the technical field of medical equipment for osteotomy and orthopedics, in particular to an auxiliary equipment for osteotomy and orthopedics. Background Art

[0002] Corrective osteotomy is a common surgery for the treatment of knee osteoarthritis. High tibial osteotomy, or HTO, is the most commonly used corrective osteotomy for the treatment of knee osteoarthritis. In traditional corrective osteotomy, an electric drill and an electric oscillating saw are used to perform osteotomy or bone sawing operations on the patient's bones, that is, the patient's bones are drilled by the electric drill, and the patient's bones are cut or osteotomized by the oscillating saw. However, in actual corrective osteotomy, medical staff need to frequently replace the two instruments for osteotomy, and after each instrument replacement, the inclination angle of the electric drill or oscillating saw needs to be manually adjusted to align the output end of the electric drill or the oscillating saw with the drilling position. The above operations make the preparation process after each instrument replacement more cumbersome, resulting in low efficiency and long time-consuming for the entire operation. At the same time, due to the long operation time and the need for frequent operation or replacement of instruments for surgery, the medical staff consumes a lot of physical energy. Summary of the invention

[0003] In view of the shortcomings of the existing technology, the present invention provides an auxiliary device for osteotomy and correction surgery to solve the problem that the operation of sawing or drilling the bone at the patient's osteotomy position in traditional osteotomy and correction surgery is cumbersome and consumes a lot of physical strength and time of medical staff.

[0005] The above technical solution is beneficial in that: before performing osteotomy correction surgery, the medical staff fixes the bracket on one side of the operating table, and then lets the patient lie on the operating table and adjusts the patient's posture, and then adjusts the position of the operating member through the CT image, that is, first adjusts the position of the adjustment disk through the first adjustment member, and makes the adjustment disk rotate axially relative to the rotating shaft through the first adjustment member, so as to adjust the relative circumferential position of the output end of the operating member and the patient's osteotomy position, and then adjusts the relative inclination angle between the operating member and the rotating shaft through the second adjustment member, so that the operating member can be aligned with the patient's osteotomy position, and then the medical staff adjusts the position of the operating member according to the bone drilling depth. The operating parameters of the operating part output end are set according to the requirements or osteotomy depth requirements, that is, the parameters are set through the setting part, so that the driving part can drive the operating part to move according to the set parameters during osteotomy and correction; the semi-automatic osteotomy in osteotomy is realized through the setting of the above-mentioned technology, so as to improve the operation efficiency and accuracy. At the same time, after the preliminary setting, the osteotomy position of the patient can be automatically osteotomized or drilled through the operating part, so that the medical staff does not need to frequently replace the drilling instrument and the osteotomy instrument, so as to reduce the physical and energy loss of the medical staff, and then the medical staff can perform more osteotomy and correction operations.

[0006] The present invention is further provided with: an adjustment block movably arranged on the adjustment disk, the adjustment block is hollow with an inner cavity, the operating member comprises an electric oscillating saw arranged for sawing bones at the osteotomy position of an external patient and an electric bone drill arranged for drilling bones at the osteotomy position of an external patient, the electric oscillating saw and the electric bone drill are both arranged in the inner cavity and the electric oscillating saw and the electric bone drill are arranged relatively to each other, a fixing plate is arranged in the inner cavity corresponding to the positions of the electric oscillating saw and the electric bone drill, the two fixing plates are respectively detachably connected to the electric oscillating saw and the electric bone drill, a saw head is detachably connected to the output end of the electric oscillating saw, and a drill bit is detachably connected to the output end of the electric bone drill, openings are opened on the adjustment block corresponding to the positions of the saw head and the drill bit, the two openings are both connected to the inner cavity, and the electric bone drill and the electric oscillating saw are both arranged in linkage with the driving member.

At the same time, the saw head and the electric oscillating saw are detachably connected, and the drill bit and the electric bone drill are detachably connected, so as to replace disposable drill bits and saw heads, thereby avoiding bacterial infection, and also facilitating the disinfection of the electric bone saw and the electric oscillating saw; the electric oscillating saw and the electric bone drill in the above technology are both existing technologies, so their structure and function will not be described in detail, and at the same time, the on and off switches of both are set on the adjustment block or communicated with external intelligent industrial control equipment for operation by medical staff.

[0008] The present invention is further configured as follows: the two fixed plates are arranged opposite to each other and an adjustment gap is formed therebetween; the driving member includes an electric push rod and a linkage gear set arranged in the adjustment gap; tooth grooves are provided on the opposite surfaces of the two fixed plates along the length direction of the fixed plates; the two tooth grooves are meshed with the linkage gear set; the electric push rod is arranged at the tail of the adjustment block; the output end of the electric push rod is placed in the inner cavity and is connected to a transmission shaft at the end of one of the fixed plates.

[0009] The advantages of adopting the above technical solution are as follows: when it is necessary to drive either the electric oscillating saw or the electric bone drill to operate, the electric push rod is started to extend its output end, and when the output end of the electric push rod is extended, it will drive the transmission shaft to move, and when the transmission shaft is driven to extend, it will drive the fixed plate connected to it to move, and if an electric bone drill is set on the fixed plate, the movement of the fixed plate will drive the electric bone drill to move, so that the drill bit of the electric bone drill passes through the adjustment block and contacts the patient's osteotomy position, and when the fixed plate is extended, the tooth groove on the fixed plate is meshed with the linkage gear set, and the two tooth grooves are arranged opposite to each other, so that the tooth groove of the fixed plate drives the linkage gear to rotate counterclockwise, and when the linkage gear rotates counterclockwise, it will drive the other fixed plate to move , that is, the two fixed plates move in opposite directions, so as to realize the retraction of the saw head of the electric oscillating saw into the adjustment block, thereby avoiding being affected when the electric bone drill is drilling, and avoiding interference with the line of sight, thereby improving the surgical efficiency and surgical accuracy; based on the above description, when the electric push rod is closed, its output end retracts, at this time the transmission shaft moves and drives the fixed plate to retract, and when the fixed plate retracts, it drives the linkage gear set to rotate clockwise, so that the other fixed plate slides, so that the saw head of the electric oscillating saw on the other fixed plate passes through the adjustment block, thereby contacting the osteotomy position of the patient outside, and when the saw head extends out of the adjustment block, the drill bit will retract the adjustment block, thereby avoiding interference between the two; the above-mentioned technical settings improve the surgical efficiency and surgical accuracy.

The fixed plate connected to the matching shaft is defined as a fixed plate on which an electric bone drill is installed, and the fixed plate connected to the transmission shaft is defined as a fixed plate on which an electric swing saw is installed. When the fixed plate on which the electric bone drill is installed moves, the matching shaft moves synchronously, and the slide plate connected to the matching shaft slides toward the direction of the adjacent stop plate. When the stop plate is moved a certain distance, it fits with the slide plate, and at this time, the stop button on the stop plate abuts and cooperates with the slide plate, making the stop plate stop. The slide plate triggers the stop button, causing the electric push rod to stop and maintain the current state, that is, after the drill bit of the electric bone drill drills to a certain depth, the electric push rod no longer drives the electric bone drill to move, thereby realizing the stop of the drill bit at the current position, thereby preventing the drill bit from going too deep and causing damage to the patient; based on the above description, the stop operation of the electric oscillating saw is equivalent to the above principle, so it will not be described in detail; the setting of the above technology is used to realize the stop operation of the electric bone drill and the electric oscillating saw, thereby preventing the drill bit or saw head from over-drilling or over-sawing the bone at the patient's osteotomy position, thereby avoiding surgical accidents.
