[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element.

[0021] like Figure 1 , 2 As shown, an embodiment of the present application provides a protective sleeve, comprising: a protective sleeve, comprising: a sleeve body 10, a fixing portion 20 and an elastic wire 30, the elastic wire 30 is wound around the sleeve body 10, one end of the elastic wire 30 is connected to one end of the sleeve body 10, and the other end of the elastic wire 30 is connected to the other end of the sleeve body 10, and the elastic wire 30 can make the sleeve body 10 expand into a cylindrical shape; both ends of the sleeve body 10 are fixed with the fixing portion 20, so as to close the opening of the sleeve body 10.

[0022] After the protective sleeve is disinfected, before the operation, the sleeve body 10 is manually opened into a cylindrical shape, and after the protective sleeve is put on the instrument, the two ends of the opening are closed with the fixing part 20, so that the protective sleeve wraps the instrument to prevent contamination of the sterile environment. By arranging the elastic wire 30 on the sleeve body 10, the sleeve body 10 can be opened by pinching the two ends of the elastic wire 30 and pulling them apart, so that the protective sleeve is easy to open, takes less time, reduces the preoperative preparation time, shortens the patient's operation time, and improves work efficiency; the elastic wire stretches the sleeve body, and when the protective sleeve is removed, it will not be roughly pulled due to too small a space.

[0023] In one embodiment, the elastic thread 30 is spirally arranged on the sleeve 10, and the elastic thread 30 can be folded along the length direction of the sleeve 10, so that the sleeve 10 is folded along its length direction; the elastic thread 30 can be stretched along the length direction of the sleeve 10, so that the sleeve 10 is stretched along its length direction. The elastic thread 30 is spirally arranged on the sleeve, which is convenient for the sleeve 10 to be opened or folded. When the elastic thread 30 is opened, the cylindrical sleeve 10 can wrap the instrument to isolate the instrument from the sterile environment. When the elastic thread 30 is folded, the protective sleeve can be sterilized.

[0024] In one embodiment, the protective sleeve further comprises a covering belt 40, which is fixed on the sleeve body 10 and covers the elastic wire 30 to surround the elastic wire 30 on the sleeve body. The covering belt 40 is fixed on the sleeve body 10 to prevent the elastic wire 30 from moving when it is spirally wrapped around the sleeve body 10, so as to facilitate the quick opening of the sleeve body 10.

[0025] In one embodiment, the sleeve 10 includes a first sleeve 101 and a second sleeve 102 , wherein a first end of the first sleeve 101 is connected to a first end of the second sleeve 102 , and a second end of the first sleeve 101 is connected to a second end of the second sleeve 102 .

[0026] In one embodiment, the first cover 101 is a transparent film, and the second cover 102 is a colored film. Conventional protective covers are very easy to be damaged, but it is difficult to observe the damage at the specific position on the protective cover, and there is a possibility of contaminating the sterile area. Therefore, during the manufacturing process, the first cover 101 is set as a transparent surface, and the second cover 102 is set as a colored surface. The second cover 102 with a colored surface is used as a control for the transparent first cover 101, so that it can be quickly observed whether the cover 10 is damaged. If it is damaged, it can be quickly replaced to prevent the damage from not being discovered in time, destroying the sterile environment, and causing surgical failure.

[0027] Specifically, the second cover 102 is yellow, which is convenient for comparison with the transparent surface of the first cover 101, and for checking whether the protective cover is damaged. If the protective cover is damaged, the protective cover is replaced to avoid damaging the sterile environment and causing surgical failure.

[0028] In one embodiment, the fixing part 20 is a Velcro, which includes a first patch 201 and a second patch 202. The first surface of the first patch 201 is fixed to the sleeve 10, the first surface of the second patch 202 is fixed to the sleeve 10, and the second surface of the first patch 201 can be attached and connected to the second surface of the second patch 202 to close the opening of the sleeve 10. The Velcro is used to close the opening of the sleeve 10, which is convenient for opening and closing.

[0029] like Figure 3 As shown, in another embodiment, the fixing part 20 includes a connecting cover 211 and a button 212, the first end of the connecting cover 211 is fixed to the sleeve 10, and the second end is provided with an opening; the first end of the connecting cover 211 is fixed to one side of the end of the sleeve 10, and the button 212 is fixed to the other side of the end of the sleeve 10, and the opening can be covered on the button 212 to close the opening of the sleeve 10. The connecting cover 211 and the button 212 are used to facilitate opening and closing.

[0030] The protective cover is originally folded, and a Velcro or connection cover 211 is provided at the opening to close the opening. When removing the protective cover, the Velcro is opened or the connection cover 211 is separated from the button 212. The fixing part 20 can be a magnetic element with magnetic force or a buckle that can be mutually held.

[0031] Traditional protective sleeves use cotton ropes to fix instruments, which increases the process of tying knots. After the operation, the knot needs to be manually untied or cut with scissors, which wastes time and increases the loss of surgical instruments. Therefore, the fixing portion in the present application uses Velcro or a connecting cover button to close the end of the sleeve body 10, avoiding the use of cotton ropes to fix instruments. After the operation, there is no need to manually untie the knot, reducing the increase in surgical instrument loss due to cutting the cotton rope with scissors.

[0032] In one embodiment, the elastic wire 30 is an elastic wire made of nickel-titanium alloy memory material. Compared with other materials, shape memory alloys have good shape memory effect, excellent superelasticity, good damping characteristics, wear resistance and corrosion resistance, and have been widely used in clinical and medical equipment. Nickel-titanium alloy shape memory alloys will automatically restore their shape after a certain heat treatment, and this change is the shape memory characteristic of nickel-titanium alloy shape memory alloys. Shape memory can be divided into one-way shape memory, two-way shape memory and full-range shape memory according to the recovery status. Superelastic nickel-titanium alloy shape memory alloys will deform when subjected to external forces, and will return to their original state after removing the external forces. This is the superelastic characteristic of nickel-titanium alloy shape memory alloys. After superelastic deformation, nickel-titanium alloy shape memory alloys will directly lead to martensitic phase transformation, and removing the external force will lead to reverse martensitic phase transformation. Nickel-titanium alloy shape memory alloys have very good damping properties because of the self-adjustment of phase transformation and the interface and movement generated in the phase transformation.

[0033] In one embodiment, a guide rope 50 is further included, one end of which is fixed to the sleeve 10 and located in the cylinder, and the other end of which extends beyond the end of the sleeve 10. Since the sleeve 10 is generally two meters long, it is difficult to put the sleeve 10 on the machine if it is opened directly and completely, so the guide rope 50 is provided. A guide rope 50 is held in the hand to put one end of the sleeve 10 on the machine, and then the sleeve 10 is opened so that the device is wrapped in the sleeve 10.

[0034] The traditional method of putting the protective cover on the instrument is to use the thumbs and wrists of both hands to loosen and separate the tightly attached protective cover, but both hands will feel sore after separation, and the operation efficiency is low. Therefore, the left hand is used to bear the weight, and the right hand is used to assist in separating the protective cover, which is simple and easy to learn, and very labor-saving to operate.

[0035] In one embodiment, the sleeve 10 is a film made of polyethylene material. When the sleeve 10 is opened, a cavity is formed inside, and the cavity is used to wrap the surgical instrument. The sleeve is made of polyethylene material and has a certain elasticity, which can meet the protection needs of medical instruments of different sizes. However, in actual use, in order to prevent the protective sleeve from being pulled, the cavity of the protective sleeve is generally larger than the surgical instrument and can completely wrap the surgical instrument.

[0036] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, and the lowest operating temperature can reach -100℃-70℃. It has good chemical stability and can withstand the corrosion of most acids and alkalis, but is not resistant to oxidizing acids.

[0037] It is relatively simple to put protective covers on smaller devices such as wires. When tidying up the sterile instrument table, the instrument nurse cuts open the seal of the inner sterile packaging bag and takes out the sterile protective cover. Put the sterile packaging bag into the left fingers, exposing the thumb to fix the protective cover. Put the open end of the sterile protective cover into the left fingers covered with the sterile packaging bag, and the four fingers are spread out to the same diameter as the sterile packaging bag. The left hand bears the weight, and the right hand helps to quickly put the protective cover into the left hand until the tail end. After the tail end, cut the tail end seal, put the sterile protective cover on the wire with the touchless method, and then connect the wire to the sterilized instrument. The advantages of this operation method are mainly: the left hand bears the weight instead of the thumb of both hands, avoiding the soreness of both hands due to excessive force, which is fast and labor-saving, thereby effectively improving the efficiency of surgical operation. At the same time, the operation is simple, the time used is short, and it is easy to learn and master. It is convenient to obtain materials, economical and affordable, and saves surgical costs. This method is suitable for medical sterile protective covers of various specifications and models.

[0038] This product is a disposable medical product, which is mainly used for the protection of medical devices and medical supplies that require sterile isolation protection. The main material is imported polyethylene film. This product is sterile packaging. It can be directly put on the wire or instrument before the operation to fully ensure the sterile environment of the operation area. It can be removed once after the operation, which is convenient and clean, reducing the workload of medical staff, and effectively saving the cost of instrument maintenance and wire replacement. The sterile protective cover is a product packaged and sealed in a composite paper-plastic bag. It is sterilized with ethylene oxide and passed various performance tests before it is supplied to medical institutions or individuals. After sterilization, the sterile protective cover is a sterile product, which is limited to one-time use and should be destroyed after use.
