Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable gynecological skin preparation knife. Background Art
[0002] Skin preparation before gynecological surgery (skin preparation) is a necessary step to ensure the completion of the operation and is also one of the routine gynecological care. Skin preparation is to remove hair and dirt from the surgical area. Skin preparation can improve the surgical field of view, reduce the postoperative incision infection rate, and prevent the injured area from becoming a base for bacterial growth.
[0003] Skin preparation requires a skin preparation knife, but existing skin preparation knives have fixed-length handles. This fixed-length handle is easily obstructed by the thighs when treating the perineum, resulting in limited operating space and increasing the risk of scratches during skin preparation. Furthermore, the fine hair attached to the perineum after skin preparation is difficult to clean, making the procedure inconvenient. Utility Model Content
[0004] The utility model aims to provide a disposable gynecological skin preparation knife which can adjust the handle length, reduces the situation of space limitation, and is convenient for cleaning fine hair.
[0005] To achieve the above objectives, the technical solution of the present utility model is as follows.
[0006] A disposable gynecological skin preparation knife comprises a protective housing, a blade mounted within the housing, both sides of the blade extending outside the housing, and comb teeth disposed on both sides of the housing. A fixing rod is mounted on the outer surface of the housing, a sleeve sleeved on the outer surface of the fixing rod, and sockets are formed on both sides of the sleeve's outer surface along its length. A fixing mechanism is disposed within the fixing rod, adapted to engage with the sockets.
[0007] It can be seen that the purpose of extending and fixing the sleeve can be achieved by plugging the fixing mechanism into the two sockets, so the length of the handle can be adjusted. When the handle length increases, a better hand-holding experience can be obtained. When the handle length is shortened, it is convenient to prepare the skin in a narrow area without being obstructed by the thighs on both sides, thereby reducing the risk of skin preparation. Moreover, through the setting of the comb teeth, a gap can be reserved between the blade and the skin, which can achieve the purpose of skin preparation and avoid scratches.
[0008] Furthermore, the fixing mechanism includes an inner groove opened inside the fixing rod, a push rod is provided inside the inner groove, a spring is provided inside the inner groove, and two ends of the spring are respectively in contact with the push rod and the inner wall of the inner groove.
[0009] Pressing the push rod inward and retracting it into the sleeve can cancel the fixation between the push rod and the socket. Then the sleeve can be slid to align the other socket with the push rod. At this time, the compressed spring releases the elastic force, which can push the push rod to automatically insert into the socket for fixation, thereby completing the purpose of adjusting the handle length.
[0010] Furthermore, two side blocks are installed on the outer surface of the protective shell, a reel is rotatably connected between the two side blocks, and the outer surface of the reel is wrapped with medical tape.
[0011] When the skin preparation is completed, medical tape can be used to stick the fine hairs on the skin, so as to achieve the purpose of quick cleaning and improve the efficiency of skin preparation.
[0012] Furthermore, a rubber sleeve is provided on the outer surface of the sleeve, and anti-slip grooves are provided on the outer surface of the rubber sleeve.
[0013] The provision of the rubber sleeve and the anti-slip grooves can increase the friction between the sleeve and the hand, reduce hand slippage and improve the stability of skin preparation.
[0014] Furthermore, a limiting groove is provided on the outer surface of the fixing rod along its length direction, and a limiting block is provided on the inner wall of the sleeve, and the limiting block is adapted to the limiting groove.
[0015] By setting the limiting groove and the limiting block, the angle of the sleeve can be limited, so that after the sleeve is put on the fixed rod, the push rod can be accurately at the same angle as the socket, thereby improving the adjustment efficiency of the handle length.
[0016] Furthermore, a non-stick layer is provided at the end of the medical tape.
[0017] By setting the non-stick layer, the medical tape can be torn off quickly and easily to stick to fine hairs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The present invention is described in detail below with reference to the accompanying drawings.
[0024] like Figure 1-4 As shown, a disposable gynecological skin preparation knife includes a protective housing 100, with a blade 101 mounted inside the protective housing 100. Both sides of the blade 101 extend outside the protective housing 100, and comb teeth 102 are provided on both sides of the protective housing 100. A fixing rod 103 is mounted on the outer surface of the protective housing 100, and a sleeve 104 is sleeved on the outer surface of the fixing rod 103. The outer surface of the sleeve 104 has sockets 105 on both sides of its length. The fixing rod 103 is provided with a fixing mechanism 200 that can be plugged into the socket 105.
[0025] During use, the purpose of extending and fixing the sleeve 104 can be achieved by plugging and cooperating the fixing mechanism 200 with the two jacks 105, so the length of the handle can be adjusted. When the handle length increases, a better hand-holding experience can be obtained. When the handle length is shortened, it is convenient to prepare the skin in a narrow area without being obstructed by the thighs on both sides, thereby reducing the risk of skin preparation. The end of the comb teeth 102 is 1 mm longer than the end of the blade 101, so that a 1 mm gap can be reserved during the skin preparation process, which can achieve the purpose of skin preparation and avoid scratches. It is worth mentioning that talcum powder can be sprinkled on the skin preparation area before skin preparation, which can effectively protect the integrity of the patient's skin, and there are no bleeding points in the skin preparation area, reducing the patient's pain and increasing the patient's comfort and satisfaction with skin preparation. Adding talcum powder before skin preparation can increase the smoothness of the skin, reduce friction, and avoid nurses having to spend time dealing with bleeding points during skin preparation, thereby improving work efficiency.
[0026] Specifically, the fixing mechanism 200 includes an inner groove 201 opened inside the fixing rod 103, a push rod 202 is provided inside the inner groove 201, and a spring 203 is provided inside the inner groove 201. The two ends of the spring 203 are respectively in contact with the push rod 202 and the inner wall of the inner groove 201. The push rod 202 is pressed inward and retracted into the sleeve 104, which cancels the fixation between the push rod 202 and the socket 105. Then the sleeve 104 can be slid to align the other socket 105 with the push rod 202. At this time, the compressed spring 203 releases the elastic force, which can push the push rod 202 to automatically insert into the socket 105 for fixation, thereby completing the purpose of adjusting the handle length.
[0027] Specifically, two side blocks 300 are installed on the outer surface of the protective shell 100, and a winding shaft 301 is rotatably connected between the two side blocks 300. The outer surface of the winding shaft 301 is wrapped with medical tape 302. When the skin preparation is completed, the medical tape 302 can be used to stick the fine hair on the skin, thereby achieving the purpose of quick cleaning and improving the skin preparation efficiency.
[0028] Specifically, the outer surface of the sleeve 104 is provided with a rubber sleeve 400, and the outer surface of the rubber sleeve 400 is provided with anti-slip grooves. The setting of the rubber sleeve 400 and the anti-slip grooves can increase the friction between the sleeve 104 and the hand, reduce hand slippage and improve the stability of skin preparation.
[0029] Specifically, a limiting groove 500 is provided on the outer surface of the fixing rod 103 along its length direction, and a limiting block 501 is provided on the inner wall of the sleeve 104. The limiting block 501 is adapted to the limiting groove 500. By setting the limiting groove 500 and the limiting block 501, the angle of the sleeve 104 can be limited, so that after the sleeve 104 is sleeved on the fixing rod 103, the push rod 202 can be accurately at the same angle as the socket 105, thereby improving the adjustment efficiency of the handle length.
[0030] Specifically, a non-stick layer 600 is provided at the end of the medical tape 302. Due to the provision of the non-stick layer 600, the medical tape 302 can be torn off quickly and conveniently to adhere to fine hairs.
