Description

Technical Field

[0001] The utility model relates to the field of occupational protection for limb surgeries. A protective device for providing protection against aerosols, splashes and surgical smoke for surgical staff, in particular to a device for intraoperative occupational protection and aseptic technique for limb surgeries. Background Art

[0002] During limb surgeries, instruments such as oscillating saws, burr drills and irrigation guns are used. These instruments are very likely to generate a large range of aerosols or splashes during operation. On the one hand, these aerosols and splashes will increase the risk of occupational exposure for medical staff; on the other hand, the splashes that come into contact with the non-sterile areas such as the head and face of the surgical staff may fall back onto the sterile surgical area again, causing contamination of the sterile surgical area and increasing the risk of surgical site infection for patients. Especially for limb surgeries such as knee joint replacement, there are more bone chips and other splashes and aerosols generated during the operation, and the risk of occupational exposure and contamination of the sterile area is relatively high. Once an infection occurs, it will have a greater impact on the health and medical expenses of the patients. Therefore, the protection against splashes and aerosols during limb surgeries is particularly important. Summary of the Invention

[0003] In order to achieve the protection against splashes and aerosols during limb surgeries and reduce the risks of occupational exposure and contamination of the sterile surgical area, this negative-pressure type limb surgery protective cover is designed.

[0004] 1. The technical solution adopted by the utility model to solve its technical problems is composed of a protective cover, a bracket and a base. The protective cover is composed of a transparent protective screen, a circular hollow framework and negative-pressure suction holes. The bracket is composed of an upper support rod, a lower support rod, an upper joint, a middle joint, a lower joint, an upper connecting pipe, a middle connecting pipe and a lower connecting pipe. The base is composed of a cross beam, a fixing clip 1 and a fixing clip 2, thus constituting the utility model.

[0005] 2. The protective cover is composed of a transparent protective screen, a circular hollow framework and negative-pressure suction holes. The transparent protective screen adopts a dome-shaped outer design, with a diameter of 30 cm and a height of 2 cm, and a high-transparency material is selected. The circular hollow framework is formed by enclosing a hollow PVC pipe (inner diameter 0.5 cm, outer diameter 0.7 cm), and the framework diameter is 30 cm. The negative-pressure suction holes are circular openings with a diameter of 0.2 cm, located on the inner side wall of the circular hollow framework.

[0006] 3. The bracket is composed of an upper support rod, a lower support rod, an upper joint, a middle joint, a lower joint, an upper connecting pipe, a middle connecting pipe, and a lower connecting pipe. Both the upper support rod and the lower support rod are hollow with closed ends at both ends, with dimensions of 2 cm * 2 cm * 20 cm, and the hollow part is designed with an inner diameter of 0.5 cm. The upper joint, the middle joint, and the lower joint are all designed with screws and nuts. Rotating the screw can adjust the tightness of the joint. The upper joint is the connection between the protective cover and the upper support rod, the middle joint is the connection between the upper support rod and the lower support rod, and the lower joint is the connection between the lower support rod and the base. The upper connecting pipe and the middle connecting pipe are designed as flexible pipes with an inner diameter of 0.5 cm and an outer diameter of 0.7 cm, which is convenient for adjusting the upper joint and the middle joint. The upper connecting pipe is responsible for connecting the circular hollow framework and the upper support rod, and the middle connecting pipe is responsible for connecting the upper support rod and the lower support rod. The lower connecting pipe is designed as a rigid pipe with an inner diameter of 0.8 cm and an outer diameter of 1.0 cm, which is responsible for connecting the lower support rod and the negative pressure suction device.

[0007] 4. The base is composed of a cross beam, fixing clip 1, and fixing clip 2. The middle of the cross beam is connected to the lower support rod through the lower joint. Both fixing clip 1 and fixing clip 2 are spring-type fixing clips, which are respectively located at both ends of the cross beam and can fix the protective cover on the patient's limb.

[0008] During use, the overall four-limb surgical protective cover needs to be sterilized. After the sterile surgical drape is laid, the scrub nurse on stage takes out the four-limb surgical protective cover from the sterile package. Fix the protective cover on the limb above or below the incision through the fixing clip. By adjusting the upper joint, the middle joint, and the lower joint, make the protective cover located at an appropriate position above the incision, connect the lower connecting pipe to the existing negative pressure suction device in the operating room, and establish a negative pressure environment within the dome range of the protective cover. During the operation, the position of the fixing clip and the position of the protective cover can be adjusted at any time according to the surgical needs.

[0009] The positive effects of the present utility model are as follows:

[0010] 1. Through the direct blockage of the protective screen, the present utility model can effectively control the dispersion range of aerosols and splashes, and reduce the risk of occupational exposure of medical staff and contamination of the surgical sterile area.

[0011] 2. The negative pressure suction design of the present utility model can timely suck out aerosols, surgical smoke, etc. generated within the range of the protective cover, further reducing the risk of occupational exposure of medical staff.

[0012] 3. The present utility model has a simple structure and is convenient to operate. Description of the Drawings

[0013] The following further describes the implementation of the present utility model in conjunction with the drawings.

The bracket is composed of an upper support rod (12), a lower support rod (10), an upper joint (13), a middle joint (4), a lower joint (9), an upper connecting pipe (3), a middle connecting pipe (11) and a lower connecting pipe (5). The base is composed of a cross beam (6), a fixing clip 1 (7) and a fixing clip 2 (8), thus constituting the present utility model.

[0018] Before use, the whole four - limb operation protective cover needs to be sterilized. During use, as Figure 3 shown, after the sterile drapes for the operation are laid, the scrub nurse on stage takes out the four - limb operation protective cover from the sterile package. Fix the protective cover on the limb (16) above or below the incision through the fixing clips (7)(8). By adjusting the upper joint (13), the middle joint (4) and the lower joint (9), make the protective cover in an appropriate position above the incision to ensure that there is enough operating space for the surgical equipment (15). Connect the lower connecting pipe (5) to the existing negative pressure suction device in the operating room to establish a negative pressure environment within the dome range of the protective cover. During the operation, the positions of the fixing clips (7)(8) and the position of the protective cover can be adjusted at any time according to the operation requirements.
