Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hook for surgical drapes and an anti-slip drape assembly including the hook. Background Technology

[0002] A surgical drape is a surgical drape specifically designed for performing surgery on specific areas of a patient. This drape has holes made for specific surgical sites, allowing the surgeon to perform the operation through the pre-set holes.

[0003] Current surgical drapes are simply laid directly on the patient. Because the drape is not secured, it is prone to slippage during surgery, requiring constant adjustments by medical staff to prevent interference with the surgeon's work. Externally securing the drape can compromise aseptic technique; the drape must be able to hang more than 30cm from the circumference of the operating table to form a sterile barrier. While the dimensions of surgical drapes are relatively fixed, patient variations in height and build lead to different degrees of slippage, making standardized securing difficult.

[0004] Research is needed on how to secure surgical drapes to prevent slippage during surgery, which could interfere with the surgeon's work; at the same time, the securing method should not violate the aseptic principles of the operating room or damage the sterile barrier; and the securing position should be adjustable. These are the problems that need to be solved for surgical drapes.

[0005] Existing patents, such as patent 202222393302.2, describe a surgical drape that is easy to fix. This drape has fixing straps and tightening straps at each of its four corners, with a ratchet tensioner at the end of the fixing strap furthest from the drape body for locking the tightening strap. While this achieves fixation, it significantly alters the structure of the surgical drape, easily compromising the sterile barrier and greatly increasing costs.

[0006] For example, patent 202021407539.6, a medical drape fixator, includes a fixation plate that is fixed to people's skin with double-sided tape and a clamp that is fixed on the fixation plate. However, the structure is too complicated, the cost is high, and the operation is cumbersome.

[0007] The above background information is provided only to assist in understanding the inventive concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed before the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0008] In view of this, in order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a hook for fixing surgical drapes, preventing them from slipping, not damaging the sterile barrier, and facilitating the installation and removal of surgical drapes.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A hook for securing surgical drapes, the surgical drape having a fixing hole that mates with the hook, the hook comprising a fixing part, a connecting part, and an inserting part, wherein the fixing part is used to secure the hook, the side of the fixing part away from the connecting part is a plane, and the side of the inserting part away from the connecting part is a first arc surface, the first arc surface protruding away from the connecting part, i.e., the opening of the first arc surface facing the connecting part; in the cross-sectional direction of the connecting part, the size of the inserting part is larger than the size of the connecting part.

[0011] According to some preferred embodiments of this utility model, the length direction of the connecting portion is the connection direction between the fixing portion and the guiding portion. The connecting portion is elongated.

[0012] According to some preferred embodiments of the present invention, the vertex of the first arc surface is located on the center line of the connecting portion.

[0013] According to some preferred embodiments of the present invention, the first arc surface is a portion of a sphere. Preferably, the first arc surface is a hemisphere.

[0014] According to some preferred embodiments of the present invention, the center of the sphere is located on the center line of the connecting portion.

[0015] According to some preferred embodiments of this utility model, the connecting part is cylindrical, and the center of the sphere and the vertex of the first arc surface are both located on the axis of the connecting part. That is, the connecting part is linked to the center of the hemispherical inlet, forming a shape similar to an umbrella or mushroom.

[0016] According to some preferred embodiments of this utility model, the side of the guide portion near the connecting portion is a concave second arc surface. The second arc surface is circumferentially arranged along the end of the connecting portion, and the second arc surface protrudes in a direction away from the connecting portion, that is, the opening of the second arc surface faces the connecting portion, and the opening direction is the same as that of the first arc surface. The advantage of this arrangement is that when the fixing hole of the surgical drape passes through the guide portion, the fixing hole is opened, and the blocking part between the holes fits against the connecting portion and faces the second arc surface. When the surgical drape is pulled outward, the blocking part moves along the connecting portion to the blocking surface, and is finally blocked by the blocking surface and the edge of the guide portion, preventing the drape from detaching and falling off.

[0017] According to some preferred embodiments of the present invention, the second arc surface includes blocking surfaces symmetrically arranged on both sides of the connecting portion, the openings of the blocking surfaces facing the connecting portion.

[0018] According to some preferred embodiments of this utility model, the connection between the fixing part and the connecting part has a third arc surface, which is circumferentially arranged along the other end of the connecting part. That is, the hook in this application has curved or arc surfaces everywhere, without any sharp parts, to avoid collision injuries to personnel.

[0019] According to some preferred embodiments of the present invention, the size of the fixing part is larger than the size of the connecting part projected onto the fixing part.

[0020] According to some preferred embodiments of the present invention, the size of the fixing part is less than or equal to the size of the inlet part projected onto the fixing part.

[0021] This utility model also provides a non-slip surgical drape assembly that includes a surgical drape and a hook as described above.

[0022] Compared with the prior art, the advantages of this utility model are as follows: the hook of this utility model has a flat side of the fixing part, which is used to stick to the fixing object to realize the fixation of the hook. The setting of the first arc surface of the guide part allows the surgical drape to smoothly enter the connecting part and be supported on the connecting part, so that the surgical drape is blocked and fixed by the guide part.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] This invention relates to a surgical drape and its matching hooks, which solves the problem of drape slippage in existing technologies. This reduces the need for medical staff to continuously adjust the drape's position during surgery, thus avoiding interference with their procedures. Furthermore, the fixation plate and its hooks are used within the drape covering the operating table, ensuring the drape hangs more than 30cm above the table surface, preserving the sterile barrier formed by the drape and adhering to aseptic operating room principles. Additionally, the fixation plate features multiple adjustable holes to accommodate adjustments based on patient size and other factors.

[0034] Example 1 Hook 1

[0035] like Figure 1-3 As shown, the hook 1 in this embodiment, applicable to the surgical drape 6, is used to fix the surgical drape 6. The surgical drape 6 has fixing holes 8 that cooperate with the hook 1. The hook 1 includes a fixing part 2, a connecting part 3, and an inserting part 4 in sequence. The size of the fixing part 2 is larger than the size of the connecting part 3 projected onto the fixing part 2; the size of the fixing part 2 is smaller than or equal to the size of the inserting part 4 projected onto the fixing part 2.

[0036] The fixing part 2 is circular and is used to fix the hook 1. The side of the fixing part 2 away from the connecting part 3 is flat, so that the flat side of the fixing part 2 can be glued to the operating table or hospital bed.

[0037] The connecting part 3 is elongated, and its length direction is the connection direction between the fixing part 2 and the guiding part 4. In this embodiment, the connecting part 3 is cylindrical, with one end connected to the fixing part 2 and the other end connected to the guiding part 4. In the cross-sectional direction of the connecting part 3, the size of the guiding part 4 is larger than the size of the connecting part 3.

[0038] The inlet part 4 is used to pass through the fixing hole 8 and block the fixing hole 8. The side of the inlet part 4 away from the connecting part 3 is the first arc surface 51. The first arc surface 51 protrudes in the direction away from the connecting part 3, that is, the opening of the first arc surface 51 faces the connecting part 3.

[0039] The first arc surface 51 is part of a sphere, preferably a hemisphere. The center of the sphere and the vertex of the first arc surface 51 are both located on the axis of the connecting part 3. That is, the connecting part 3 is connected to the center of the hemispherical inlet part 4, forming a shape similar to an umbrella or mushroom.

[0040] The inlet portion 4 has a concave second arc surface 52 on the side near the connecting portion 3. The second arc surface 52 is circumferentially arranged along the end of the connecting portion 3 and protrudes in a direction away from the connecting portion 3, that is, the opening of the second arc surface 52 faces the connecting portion 3, which is the same as the opening direction of the first arc surface 51. The second arc surface 52 includes blocking surfaces 54 symmetrically arranged on both sides of the connecting portion 3, and the openings of the blocking surfaces 54 face the connecting portion 3.

[0041] The advantage of this design is that when the fixing hole 8 of the surgical drape 6 passes through the inlet 4, the fixing hole 8 is opened, and the blocking part 82 between the holes fits onto the connecting part 3 and faces the second arc surface 52. When the surgical drape 6 is pulled outward, the blocking part 82 moves along the connecting part 3 to the blocking surface 54 and is finally blocked by the blocking surface 54 and the edge of the inlet 4, thus preventing the drape from detaching and falling off.

[0042] The connection between the fixing part 2 and the connecting part 3 has a third arc surface 53, which is circumferentially arranged along the other end of the connecting part 3. That is, the hook 1 in this application, the outer surface of the guide part 4 is hemispherical, the inner surface is a curved groove, the connecting part 3 is connected to the center of the inner surface, the connection between the fixing part 2 and the connecting part 3 is a smooth curved surface, and all parts of the hook 1 are curved or arc surfaces, without any sharp parts, to avoid collision injury to personnel, and also to facilitate disinfection without dead corners.

[0043] The bottom surface of the fixing part 2 in this embodiment has double-sided adhesive and is also covered with release paper. When in use, the release paper is removed, and the hook 1 is fixed to the hospital bed or operating table. In this embodiment, the hook 1 (fixing part 2, connecting part 3, and guiding part 4) is integrally injection molded, and the material is preferably medical TPE.

[0044] In this embodiment, the hook 1 has a flat side of the fixing part 2, which is used to adhere to the fixing object to fix the hook 1. The first arc surface 51 of the guide part 4 allows the surgical drape 6 to smoothly enter the connecting part 3 and be supported on the connecting part 3, so that the surgical drape 6 is blocked and fixed by the guide part 4.

[0045] Example 2: Anti-slip Towel Component

[0046] like Figure 1-7 As shown, the anti-slip surgical drape assembly in this embodiment includes a surgical drape 6 and a hook 1 for securing the surgical drape 6. The hook 1 is the structure provided in Embodiment 1. The surgical drape 6 has a transparent plastic film, an absorbent pad, and an operating hole 9. The transparent plastic film is fixed to the left edge of the drape body. The absorbent pad is fixed to the drape fabric with the operating hole 9 as its center, and the operating hole 9 is provided through the drape.

[0047] The surgical drape 6 has a fixing hole 8 that mates with the hook 1. The guide portion 4 of the hook 1 passes through the fixing hole 8 to secure the surgical drape 6. In this embodiment, the anti-slip drape assembly, through the cooperation of the fixing hole 8 and the hook 1, allows the guide portion 4 to pass through and block the fixing hole 8, thus securing the surgical drape 6, preventing slippage, maintaining the sterile barrier, and facilitating the installation and removal of the surgical drape 6.

[0048] In this embodiment, the surgical drape 6 has a connecting area 10, and a fixing piece 7 is provided in the connecting area 10. The fixing piece 7 has one or more fixing holes 8, such as... Figure 4-5 As shown, one side of the fixing piece 7 is bonded to the connecting area 10. The surgical drape 6 is hung on the hook 1 through the fixing holes 8, and the fixing position can be adjusted through multiple fixing holes 8 for easy operation.

[0049] The fixation hole 8 includes a center point and tear slits 81 extending radially outward from the center point, the tear slits 81 penetrating the thickness direction of the surgical drape 6 or the fixation piece 7. A blocking portion 82 is formed between adjacent tear slits 81, and an inserting portion 4 is used to open the blocking portion 82, the inserting portion 4 being larger than the distance between the opposing blocking portions 82. By providing the tear slits 81 and the blocking portions 82, when fixing the drape, the inserting portion 4 tears open the tear slit 81 and opens the blocking portion 82 outward. Figure 6 The hole shape in the middle. Figure 6 In the middle hole pattern, the tear seam is in the form of a narrow hole, and the spacing between each hole gradually narrows from the outside to the inside, making it easy to tear open.

[0050] Furthermore, the fixing hole 8 includes a central hole 84, the midpoint of which coincides with the center point. That is, the tear slit 81 and the blocking portion 82 radiate outwards from the center point or the central hole 84, as shown below. Figure 6 The hole configuration on the left and right sides is such that the diameter of the inlet 4 is larger than the diameter of the central hole 84, but smaller than the diameter of the entire fixing hole 8 (excluding the adjusting slot 83).

[0051] Furthermore, the fixing hole 8 includes an adjusting slit 83 extending outward from the center point, the length of which is greater than that of the tear slit 81; the adjusting slit 83 penetrates the thickness direction of the surgical drape 6 or the fixing piece 7. Preferably, the adjusting slit 83 is oriented along the sliding direction of the surgical drape 6, such that when slippage occurs, the hook 1 enters the adjusting slit 83 and is ultimately fixed in place. Figure 7 As shown.

[0052] like Figure 6 and 7 The hole pattern on the left side allows the tear slit 81 and the adjustment slit 83 to be set alternately or continuously, and they can completely or partially penetrate the thickness direction of the fixing piece 7, so that the blocking parts 82 are connected and are only torn apart when they are opened by the guiding part 4.

[0053] In this embodiment, the size of the fixing part 2 of the hook 1 is greater than or equal to the size of the fixing hole 8. The size of the connecting part 3 is less than or equal to the size of the entire fixing hole 8, and greater than the distance between the opposing blocking parts 82, that is, greater than the diameter of the central hole 84. This makes it so that after the blocking part 82 is opened by the guide part 4, it cannot fully extend on the connecting part 3 and partially adheres to the connecting part 3, bending towards the guide part 4. When the surgical drape 6 is pulled outward along the connecting part 3, the blocking part 82 moves along the connecting part 3 to the blocking surface 54, and is finally blocked by the blocking surface 54 and the edge of the guide part 4, preventing the drape from detaching and falling off.

[0054] This utility model provides an anti-slip surgical drape assembly, including a surgical drape and matching anti-slip hooks. During use, medical staff first attach the anti-slip hooks to the right side of the bed. The hooks are cleaned and disinfected after each surgery. These hooks can be reused multiple times, reducing operating costs. The outer surface of the guide portion of the anti-slip hook is hemispherical, facilitating the insertion of the anti-slip accessory and post-operative cleaning and disinfection. The connection between the connecting portion and the guide portion of the anti-slip hook is a smooth curved surface, facilitating post-operative cleaning and disinfection. The anti-slip accessory (fixing plate) of the anti-slip drape is located on the back of the drape body, ensuring that the surgical drape hangs more than 30cm above the operating table surface, without disrupting the sterile barrier formed by the surgical drape, complying with the aseptic operation principles of the operating room. The anti-slip holes of the anti-slip accessory are chrysanthemum-shaped (radiating outwards from the center), with elongated openings above the chrysanthemum-shaped holes to increase resistance and prevent slippage. The anti-slip holes of the anti-slip accessory are distributed in multiple rows and columns to meet the surgical drape fixation needs of patients of different body types.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
