TECHNICAL FIELD
[0001] The present application relates to the field of electric bone drills, and in particular, to a sterile protection device for the osteotomy process in joint replacement surgery. BACKGROUND
[0002] Joint replacement surgery is a surgical procedure that replaces damaged or diseased parts of a joint, such as the hip or knee. In joint replacement surgery, the osteotomy process is a critical step that requires precise cutting and adjustment of the patient's bones. Maintaining a sterile environment at the surgical site is crucial to prevent complications such as infection.
[0003] In traditional joint replacement surgery, surgeons typically use a bone saw to cut the bones. However, during the sawing process, a large amount of splatter and tiny particles are generated due to the high-speed rotation of the saw blade and the cutting friction of the bones. These splatters and particles may carry bacteria and other contaminants, increasing the risk of infection at the surgical site. In addition, splatters can also contaminate the surgical field, affecting the accuracy of the surgeon's operation and the effectiveness of the surgery.
[0004] Therefore, in view of the sterile protection problem in the osteotomy process of joint replacement surgery, current technological development has made some progress. For example, some surgical instruments and equipment use special materials and designs to reduce the generation and spread of splatters during sawing. In addition, there are some auxiliary devices such as aspirators and filters to remove and filter splatters and particles generated during surgery.
[0005] However, despite these technologies and devices, there are still some challenges and limitations in reducing the risk of infection at the surgical site. For example, some splatters and particles may still not be completely removed or filtered, still posing a potential risk of infection. In addition, some auxiliary devices may increase the complexity and cost of surgery, affecting their widespread application in clinical practice.
[0006] Therefore, in view of the sterile protection problem in the osteotomy process of joint replacement surgery, further research and improvement are still needed. For example, new sawing techniques and tools can be explored to reduce the generation and spread of splatters. At the same time, more effective auxiliary devices and methods can be researched to better remove and filter splatters and particles generated during surgery, thereby further reducing the risk of infection at the surgical site.
[0007] For example: Chinese invention patent CN117045307A discloses "a bone cutting protection device", the specification discloses that the traditional electric bone drill is easy to produce splatters at the drill bit during surgery, and the splatters may splash or fly to the faces of the staff, thereby affecting the progress of the surgery; the above patent can demonstrate the defects existing in the prior art.

[0068] Through the cooperation of the winding roller 510 and the rotating ring 502, slow winding can be realized through the sliding arc plate 503, and the body operation site can be bandaged.
[0069] Further, as shown in Figure 3 , Figure 8 and Figure 9 , the number of supporting rods 508 is two, one of which is used for hinging with the rotating ring 502, and the other is arranged on the annular support 3 away from the fixed ring 501, and a group of third motors 509 and winding rollers 510 are also arranged on the supporting rod 508 away from the fixed ring 501, and the supporting rod 508 away from the fixed ring 501 is fixedly connected to the annular support 3.
[0070] Further, as shown in Figure 3 , Figure 8 and Figure 9 , a supporting column 6 is hinged in a single rectangular recess 504, the lengths of the two supporting columns 6 are inconsistent, and a threaded groove is arranged at the bottom of a single supporting column 6.
[0071] The use process of the sterile protection device for arthroplasty osteotomy process provided by the application is as follows:
[0072] 1. In the use scene of the operation, the patient uses the sliding arc plate 503 to slide the limb of the operation site into the interior of the device, the anti-skid groove 505 on the sliding arc plate 503 prevents the limb from moving, and when the joint reaches the middle position, the movement is stopped, and the device bending rod 1 is kept in a horizontal state without bending, the two rotating rollers 409 are pushed to the same position and contact each other through the electric push rod 401, so that the two transparent protective films on the rotating rollers 409 form a complete shielding area, the other end of the transparent protective film is clamped by the winding roller 510, and the two rotating rollers 409 are moved away from the center position through the operation of the electric push rod 401, so that the transparent protective film on a single rotating roller 409 acts as a protection area;
[0073] 2、When a single transparent protective film is contaminated, another transparent protective film is moved to the position for alternate use, and the cleaning strip 406 on the arc-shaped rod 405 is turned to the bottom of the transparent protective film during the movement to clean the stains, so that the impurities at the bottom of the transparent protective film are cleaned. If the stains cannot be cleaned, the arc-shaped rod 405 is turned in the opposite direction and cooperates with the cutter 407 to cut the transparent protective film for replacement of a new protective film;
[0074] 3、Before the operation, the articulated support rod 508 can be moved from the rotating ring 502 to form a structure as shown in Figure 8 , under which the human body moves in the process of moving the sliding arc plate 503, and the threaded roller 506 is turned under the cooperation of the rectangular groove 504, the threaded roller 506 is turned while continuously migrating the tooth block 507 to move and further turn the rotating ring 502 on the fixed ring 501, and the winding roller 510 rotates around the fixed ring 501. The rotation speed of the winding roller 510 changes according to the movement speed of the sliding arc plate 503. At this time, the medical transparent dressing can be wound on the winding roller 510 to wrap the exposed area of the patient;
[0075] 4、When the joint part needs to be exposed during the operation, the bending rod 1 is bent to form a structure as shown in Figure 10 and Figure 11 , at this time, the single rotating roller 409 can still form a closed structure according to the change of the angle to shield the operation part to prevent the movement of internal and external impurities;
[0076] 5、When the operation environment is good and the protective device is not needed to block, the transparent protective film can be replaced by a medical sterile cloth, the arc-shaped rod 405 is turned outward, that is, toward the sterile cloth. At this time, the blade on the arc-shaped rod 405 will not contact the patient, and the arc-shaped rod 405 acts as an abutting component to bend the sterile cloth and make the sterile cloth have a point in contact with the patient. When the rotating roller 409 and the winding roller 510 move the sterile cloth under the action of the motor to produce a conveying belt-like movement effect on the surface of the patient, the stains on the surface of the patient can be wiped off, and a bacteria isolation belt can be wiped off with the medicine on the surface of the patient to prevent the body surface bacteria from entering the body;
[0077] 6、The device can still be used after the operation, and the patient can still use the winding roller 510 to change the dressing. The liquid medicine is used to dye the sterile cloth through the liquid outlet hole 410, so that the outer layer of the sterile cloth is drug-free and the inner layer is drug-containing. During the unfolding of the sterile cloth, the outer layer of the sterile cloth wipes the surface of the patient, and the inner layer of the sterile cloth applies medicine to the wound. The liquid outlet hole 410 of the rotating roller 409 is protruding, and the electric push rod 401 drives the rotating roller 409 to rotate on the surface of the human body to promote blood circulation of the specific part of the patient;
[0078] 7. Threaded holes are arranged on the bottom of the fixed ring 501 and the support 6 (threaded holes are the common connection mode in prior art, so they are not shown in the figure), which can be installed on the bed or other places by cooperating with the nuts and the ring buckle on the fixed ring 501, and the device as a whole forms a slope structure through the support 6 with different lengths, which is convenient for the recovery of patients.
