[0029] A surgical instrument tray according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] The surgical instrument tray according to the embodiment of the utility model comprises a tray body and a surgical instrument tray set 100 according to the embodiment of the utility model, and the surgical instrument tray set 100 is detachably laid in the tray body. The surgical instrument tray set 100 can be fixed to the tray body by adhesive strips or the like, and the material of the tray body can be stainless steel, etc., with high structural strength and not easy to deform, so as to facilitate the placement of the surgical instrument tray set 100 and the numerous surgical instruments on the surgical instrument tray set 100.

[0031] Reference Figure 1-Figure 2 As shown, the surgical instrument tray assembly 100 according to the embodiment of the present utility model may include: a supporting base 10 and a limiting member 20 .

[0032] Specifically, the bottom support 10 has a waterproof area. The limiting member 20 is arranged in the thickness direction of the bottom support 10 (for example Figure 2 The limiting member 20 defines a plurality of wire grooves 21, and the wire grooves 21 are arranged along a first direction (eg, Figure 1 The plurality of wire grooves 21 extend in a second direction (eg, Figure 1 The two axes are spaced apart in the front-to-rear direction (as shown), and the first direction is perpendicular to the second direction.

[0033] The surgical instrument tray set 100 can be used to place a variety of surgical instruments such as forceps, pliers, surgical sutures (such as mousse threads), etc. The wire groove 21 can be used to place surgical sutures, and multiple wire grooves 21 can respectively place surgical sutures of the same model or different models. By arranging the surgical sutures through multiple wire grooves 21, the possibility of entanglement, knotting, confusion of surgical sutures of different models, etc. can be reduced, which is convenient for medical staff to use, adapts to the cooperation with different medical staff, and is conducive to improving surgical efficiency.

[0034] For example, in some embodiments, Figure 1 As shown, the limiter 20 defines six wire grooves 21, and the six wire grooves 21 can respectively place different types of mousse threads, such as 5-0, 4-0, 3-0, 2-0, 0, and 1-0 models, among which the mousse thread of the 5-0 model is the thinnest, and the mousse thread of the 1-0 model is the thickest. Placing mousse threads of different thicknesses in different wire grooves 21 is conducive to the regularization of the mousse threads and reduces the possibility of mixing of mousse threads of different models. Different types of identification numbers are marked on the bottom 10 to facilitate medical staff to take the required type of mousse threads for easy use. Alternatively, in the six wire grooves 21, the same type of mousse threads can be placed in every two wire grooves 21, and the mousse threads are evenly placed to reduce the number of mousse threads in the same wire groove 21, which is convenient for extracting the mousse threads.

[0035] The limiting member 20 can be attached to one side of the support base 10 (for example, Figure 2The limiting member 20 may also be fixed to one side of the base 10 by other methods such as integral molding.

[0036] The limiter 20 is located in the waterproof area, so that the wire groove 21 defined by the limiter 20 is in the waterproof area, and then the surgical suture in the wire groove 21 is in the waterproof area, which can reduce the possibility of the moisture of the surgical suture volatilizing and being absorbed and gradually drying, which is conducive to keeping the surgical suture moist, reducing the possibility of the surgical suture being too dry and causing cutting of human tissue during the suturing process, reducing the possibility of the surgical suture cutting itself when tying a knot, and making the surgical suture reach a standby state, which is conducive to the use of the surgical suture. In addition, the waterproof area makes it difficult for the moisture of the surgical suture located on one side of the bottom 10 to penetrate into the other side of the bottom 10, causing the tray body to be soaked, which is conducive to ensuring the dryness of the tray body, reducing the possibility of bacterial growth and contamination of surgical instruments, and having better safety.

[0037] The first direction is perpendicular to the second direction, and the first direction can be Figure 1 The left and right directions shown, the second direction can be Figure 1 In the present application, the description of the front, back, left, right, up, down, etc. directions is based only on the directions marked in the drawings, and is not a limitation on the actual use directions of the surgical instrument tray set 100. The first direction is perpendicular to the second direction, which is conducive to improving the space utilization of the base 10, and more wire grooves 21 can be defined on the base 10 to improve the compactness of the structure.

[0038] The surgical instrument tray set 100 according to the embodiment of the utility model can reduce the arrangement of surgical instruments such as surgical sutures during surgery, making it easier for medical staff to take surgical instruments, and is beneficial for keeping the surgical sutures moist, reducing the damage to human tissue caused by the surgical sutures during suturing, thereby improving the surgical efficiency of medical staff.

[0039] Since the surgical instrument tray set 100 according to the embodiment of the utility model has the above-mentioned beneficial technical effects, the surgical instrument tray according to the embodiment of the utility model can reduce the arrangement of surgical instruments such as surgical sutures during surgery, facilitate medical staff to take surgical instruments, and help keep the surgical sutures moist, reduce the cutting of human tissues by surgical sutures during suturing, and improve the surgical efficiency of medical staff.

[0040] In some embodiments of the present invention, Figure 1-Figure 2 As shown, the base 10 includes a treatment towel 11 and a bottom plate 12 arranged on one side of the treatment towel 11 in the thickness direction, the bottom plate 12 covers a partial area of ​​the treatment towel 11, the waterproof area at least includes the bottom plate 12, and the limiting member 20 is arranged on the side of the bottom plate 12 facing away from the treatment towel 11.

[0041] The treatment towel 11 is a disposable dressing used for clinical surgery and treatment. The treatment towel 11 is made of a relatively soft material, which is conducive to buffering the placement of surgical instruments, reducing the damage caused by the collision between the surgical instruments and the tray body, and extending the service life of the surgical instruments and the tray body. In addition, the treatment towel 11 is a disposable product, which is conducive to preventing cross-infection between different patients and has good safety. In some embodiments, the treatment towel 11 is double-layered, which is easy to shape, reducing the possibility of the surgical instruments placed on the surgical instrument tray being mixed together due to the deformation of the treatment towel 11, and improving the reliability of the surgical instrument tray set 100.

[0042] The bottom plate 12 covers a part of the treatment towel 11, so that the limiter 20 defines the wire slot 21 in the area, and other areas of the treatment towel 11 can be used to place more surgical instruments. The waterproof area at least includes the bottom plate 12, and at least the limiter 20 at the bottom plate 12 is located in the waterproof area. Of course, the waterproof area can also include the area of ​​the treatment towel 11 not covered by the bottom plate 12, so as to increase the waterproof area of ​​the surgical instrument tray set 100, reduce the possibility of moisture penetrating the treatment towel 11 and soaking the tray body, and help ensure the sterile environment of the surgical instruments. For example, in some embodiments, the treatment towel 11 is a waterproof treatment towel.

[0043] In some embodiments, the base plate 12 is made of a hard material such as stainless steel or plastic that does not absorb water, which is conducive to defining a waterproof area. The base plate 12 can be fixed to the treatment towel 11 by adhesive strips or the like. In some embodiments, the stopper 20 is made of a hard material such as stainless steel or plastic that does not absorb water, so that more moisture of the surgical suture in the wire groove 21 remains in the wire groove 21, which is conducive to keeping the surgical suture moist.

[0044] In some embodiments, Figure 1-Figure 2 As shown, the surgical instrument tray set 100 further includes a flexible support member 30, which is disposed on one side of the treatment towel 11 in the thickness direction and is staggered with the bottom plate 12. The "flexible" in the flexible support member 30 means that the flexible support member 30 will deform to a certain extent after being subjected to pressure, so as to facilitate supporting hard surgical instruments such as forceps and pliers, play a buffering role in the placement of surgical instruments, and make it difficult for them to move irregularly on the surgical instrument tray set 100, which is conducive to improving the placement stability of surgical instruments on the surgical instrument tray set 100.

[0045] The material of the flexible support member 30 can be sponge, foam, etc. The flexible support member 30 can be fixed to the treatment towel 11 by adhesive strips or the like. The arrangement of the flexible support member 30 includes but is not limited to Figure 1 As shown, the flexible support member 30 is disposed on the rear side of the bottom plate 12 . The flexible support member 30 may also be disposed on the right side of the bottom plate 12 , etc., so that the flexible support member 30 and the bottom plate 12 are staggered.

[0046] Placing the hard surgical instruments on the flexible support 30 and placing the surgical sutures on the wire groove 21 is conducive to realizing a modular layout of the surgical instruments, and it is more convenient for medical staff to take the surgical instruments.

[0047] In some embodiments of the present invention, Figure 1-Figure 2 As shown, the treatment towel 11 is a rectangular towel with a side length of 91 to 120 cm; the bottom plate 12 is a rectangular plate with a long side length of 45 to 50 cm, a short side length of 30 to 35 cm, and a thickness of 0.1 to 0.2 cm; the flexible support member 30 is a cylindrical structure with an axial length of 30 to 50 cm and a diameter of 4 to 6 cm. It is conducive to adapting to the size of the tray body and can place surgical instruments required for surgery. For example, the side length of the treatment towel 11 is 91 cm, 100 cm, and 120 cm, the long side length of the bottom plate 12 is 45 cm, 47 cm, and 50 cm, the short side length of the bottom plate 12 is 30 cm, 32 cm, and 35 cm, the thickness of the bottom plate 12 is 0.1 cm, 0.15 cm, and 0.2 cm, the axial length of the flexible support member 30 is 30 cm, 40 cm, and 50 cm, and the diameter of the flexible support member 30 is 4 cm, 5 cm, and 6 cm.

[0048] In some embodiments of the present invention, Figure 1-Figure 2 As shown, the limiting member 20 includes a plurality of limiting plates 22 arranged along the second direction, the limiting plates 22 extend along the first direction, and a wire groove 21 is defined between two adjacent limiting plates 22. A plurality of wire grooves 21 can be defined by the plurality of limiting plates 22, and the adjacent two limiting plates 22 defining the wire grooves 21 can be any two adjacent ones or partially two adjacent ones, and the setting methods are various.

[0049] For example, in some embodiments, the limiting member 20 includes 12 limiting plates 22 arranged along the second direction, and any two adjacent limiting plates 22 define a wire groove 21, and a total of 11 wire grooves 21 are defined. Figure 1-Figure 2 As shown, the limiting member 20 includes 12 limiting plates 22 arranged along the second direction, two adjacent limiting plates 22 form a group and are divided into six groups in total, each group of limiting plates 22 defines a wire groove 21, and a total of six wire grooves 21 are defined. In some embodiments, the limiting plates 22 are integrally formed with the bottom plate 12 for easy manufacturing.

[0050] In some embodiments, Figure 1-Figure 2As shown, the limiting plate 22 is a rectangular plate, the long side length is 40-45 cm, the short side length is 0.3-0.5 cm, and the thickness is 0.1-0.2 cm, which is convenient for defining a long strip of wire groove 21 for placing surgical sutures. For example, the long side length of the limiting plate 22 is 40 cm, 42 cm, and 45 cm, the short side length of the limiting plate 22 is 0.3 cm, 0.4 cm, and 0.5 cm, and the thickness of the limiting plate 22 is 0.1 cm, 0.15 cm, and 0.2 cm.

[0051] In some embodiments, Figure 1-Figure 2 As shown, the surgical instrument tray assembly 100 further includes a baffle 40, which is connected to one of the two adjacent limiting plates 22 and is spaced apart from the other in the second direction, and the baffle 40 is spaced apart from the base 10 by a certain distance in the thickness direction of the base 10. The "two adjacent limiting plates 22" here refer to the two adjacent limiting plates 22 that define the same wire groove 21.

[0052] The gap between the baffle 40 and the bottom 10 in the thickness direction of the bottom 10 can be used to accommodate surgical sutures. The surgical sutures can be placed in the wire groove 21 through the gap between the baffle 40 and another limiting plate 22, and the baffle 40 can limit the wire groove 21 in the thickness direction, reducing the possibility of the surgical sutures in the wire groove 21 leaving the wire groove 21 from the baffle 40, thereby reducing the possibility of the surgical sutures being entangled with other surgical instruments, and also reducing the possibility of different types of surgical sutures being mixed together, thereby improving the reliability of placing surgical instruments in the surgical instrument tray set 100. At the same time, other surgical instruments can be placed above the baffle 40, and the space utilization rate is high.

[0053] In some embodiments, Figure 1-Figure 2 As shown, applying a force toward the support base 10 to the baffle 40 can cause the baffle 40 to deform, thereby increasing the gap between the baffle 40 and the other stopper plate 22, making it easier to place the surgical sutures. In some embodiments, the baffle 40 is made of a hard material such as stainless steel or plastic that does not absorb water, so that more moisture of the surgical sutures in the wire groove 21 remains in the wire groove 21, which is conducive to keeping the surgical sutures moist. In some embodiments, the baffle 40, the stopper plate 22 and the bottom plate 12 are integrally formed for easy manufacturing.

[0054] In some embodiments, Figure 1-Figure 2As shown, the baffle 40 is a rectangular plate, with a long side extending in the left-right direction and a side length of 40 to 45 cm, and a short side extending in the front-back direction and a side length of 1 to 1.5 cm, so as to define a long strip of baffle 40 to limit the surgical suture. The gap between the baffle 40 and another limiting plate 22 is 0.1 to 0.2 cm, so as to facilitate the placement of surgical sutures through the gap. For example, the long side lengths of the baffle 40 are 40 cm, 42 cm, and 45 cm, the short side lengths of the baffle 40 are 1 cm, 1.2 cm, and 1.5 cm, and the gaps between the baffle 40 and another limiting plate 22 are 0.1 cm, 0.15 cm, and 0.2 cm.

[0055] In some embodiments including the stop plate 22, such as Figure 1-Figure 2 As shown, the surgical instrument tray set 100 further includes a pressing plate 50, the two ends of the wire slot 21 along the first direction are open, and at least one end of the open opening is provided with a pressing plate 50, the pressing plate 50 is connected to the limiting plate 22 and is movable between a closed position and an open position with the open opening relative to the limiting plate 22. In the closed position, the pressing plate 50 partially blocks the open opening and is spaced a certain distance from the support base 10.

[0056] When the pressing plate 50 is in the open position, it is convenient to put the surgical suture into the wire groove 21 and allow the two ends of the surgical suture along the first direction to extend from the two ends of the wire groove 21, which is convenient for medical staff to take the suture. When the pressing plate 50 is in the closed position, there is a certain distance between the pressing plate 50 and the support base 10, and the pressing plate 50 does not completely cover the open mouth so that the surgical suture in the wire groove 21 can extend from the spaced gap. The pressing plate 50 presses the surgical suture at the open mouth to limit the movement of the surgical suture, which is beneficial for medical staff to extract one surgical suture at a time, reducing the possibility of extracting multiple sutures at a time, and improving the surgical efficiency of medical staff.

[0057] The two open ends of the wire slot 21 may be provided with a pressure plate 50, or only one open end may be provided with a pressure plate 50. For example, in some embodiments, Figure 1-Figure 2 As shown, a pressure plate 50 is provided at the open end of the wire groove 21 to press the surgical suture, and medical staff can extract the surgical suture from the other end, which is beneficial to reduce the water loss of the extracted surgical suture, keep the surgical suture moist, and facilitate the suture operation.

[0058] In some embodiments, the pressing plate 50 is made of a hard material such as stainless steel or plastic that does not absorb water, so that more moisture of the surgical suture in the wire groove 21 remains in the wire groove 21, which is conducive to keeping the surgical suture moist. Figure 1-Figure 2 As shown, the pressing plate 50 is a rectangular plate, the long side of which extends along the thickness direction of the support base 10 and the gap between the pressing plate 50 and the support base 10 is 0.2-0.3 cm, which is convenient for laying out the wires, and the short side of which extends along the front-to-back direction and is connected to two adjacent limiting plates 22 .

[0059] The pressing plate 50 and the limiting plate 22 may be connected by a combination of one or more connection methods such as sliding connection and snap connection. For example, in some embodiments, the limiting plate 22 is provided with a slide groove extending along the thickness direction of the base 10, and the edge of the pressing plate 50 can be slidably inserted into the slide groove. The pressing plate 50 can be switched between the open position and the closed position by sliding in the slide groove, and the adjustment method is relatively simple. And by adjusting the sliding distance of the pressing plate 50 in the slide groove, the gap between the pressing plate 50 and the base 10 can be adjusted to adjust the amount of wire that can be accommodated in the wire groove 21 and extended from the gap between the pressing plate 50 and the base 10, so as to adapt to the different numbers of surgical sutures required, and the applicability is relatively wide.
