[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments.

[0049] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the brain cotton piece placing rack comprises a back plate 101 and a liquid storage tank 102 provided at the lower end of the back plate 101 and having an opening at one end, and the back plate 101 is used for placing gelatin sponge and brain cotton piece, and the working surface 111 is a smooth surface.

[0050] The working surface of the back plate is provided as a smooth surface, and there is no other shielding structure on the working surface of the back plate; when the placing rack is used, the gelatin sponge and brain cotton piece on the working surface can be well presented in the operating field of the operator, and the operator will not have any obstacles when taking the gelatin sponge and brain cotton piece, so as to facilitate the operator to take the gelatin sponge and brain cotton piece at any position of the placing rack, improve the operation efficiency, better meet the needs of actual operation, and be more humanized in use.

[0051] The liquid storage tank 102 is a cuboid structure with an open upper end, and its size can be 16 cm in length, 3 cm in width, and 1.5 cm in depth. Correspondingly, the size of the back plate can be 16 cm in length and 10 cm in width.

[0052] The two corners of the upper end of the back plate 101 are provided with chamfered structures.

[0053] Two circular through holes 103 are provided on the back plate 101 near the upper end, and the diameter of the through holes can be 5 cm. A rope or rubber band is passed through the through holes, and the placement rack can be hung around the surgical area through the rope or rubber band to facilitate the use of the placement rack.

[0054] The back plate 101 can be made of stainless steel with a thickness of 1 mm, which has the characteristics of corrosion resistance, high and low temperature resistance, and good structural strength, and is an ideal material for surgical auxiliary devices.

[0055] The liquid storage tank 102 and the back plate 101 can be integrally formed, for example, a stainless steel plate is bent at one end of the end to form a closed groove structure, and then a welding process is used to form a liquid storage tank with an open end at the end of the back plate.

[0056] Alternatively, after the bent portion 104 in the form of a groove is integrally formed at the lower end of the back plate 101, the liquid storage tank 102 formed by injection molding is clamped into the bent portion 104, and the liquid storage tank is fixed at the lower end of the back plate through the bent portion, thereby forming the structure of the liquid storage tank at the lower end of the back plate. This forming method does not require welding process, and the processing of the placement rack is more convenient.

[0057] The placement rack with this structure is described with reference to Figure 4 The bent portion 104 has a step formed between the working surface 111 of the back plate on one side and the back plate, and the step structure is arranged such that when the liquid storage tank is arranged in the bent portion, the inner surface of the liquid storage tank close to the working surface of the back plate is flush with the working surface or the working surface is located between the inner surfaces on both sides of the liquid storage tank.

[0058] This structure is arranged considering that the sidewall of the liquid storage tank has a certain thickness, and when the liquid storage tank is assembled on the bent portion, a step will be formed between the sidewall of the open end of the liquid storage tank and the working surface of the back plate. This step will cause certain obstruction and influence to the physiological saline flowing along the back plate, resulting in that the physiological saline cannot flow into the liquid storage tank. Therefore, by forming a step at the connection position of the back plate and the bent portion, when the liquid storage tank is assembled in the bent portion, the working surface can be flush with the inner surface of the liquid storage tank or located between the inner surfaces, so that the physiological saline flowing along the back plate can smoothly flow into the liquid storage tank.

[0059] With reference to Figure 5 , Figure 6 and Figure 7The support part is arranged on the upper end of the back plate 101 and is used to support the back plate, so that when the placing rack is placed on the workbench 20, the work surface can be arranged to be inclined downward to the direction of the liquid storage groove under the support of the support part.

[0060] The support part arranged on the end of the back plate supports the upper end of the back plate, so that when the placing rack is placed on the workbench, the back plate is arranged to be inclined, so that the gelatin sponge and the brain cotton sheet on the work surface can be better presented in the operation field of view of the operator, facilitating the operation of taking, and the physiological saline seeping from the gelatin sponge and the brain cotton sheet can flow into the liquid storage groove along the inclined direction, avoiding the physiological saline from wetting the workbench or the sterile surgical drape.

[0061] Specifically, in some embodiments, the support part includes a support plate 105 hinged to the upper end of the back plate 101, and a limiting piece is arranged between the back plate 101 and the support plate 105 to limit the rotation of the support plate. The limiting piece can limit the movement of the support plate toward the back of the back plate, and when the support plate abuts against the limiting piece, the support plate 105 forms a right angle or an obtuse angle with the plane that provides support to the support plate.

[0062] The hinged connection between the support plate and the back plate can adopt a structure similar to a hinge, for example, a hinged part is integrally formed on the upper end of the back plate near the two sides, another hinged part is formed on the end of the support plate, and a hinge rod is arranged in the hinged part. Through the cooperation between the hinge rod and the hinged part on the back plate, the hinged connection of the support plate and the back plate can be achieved.

[0063] The limiting piece is arranged to limit the rotation of the support plate, so that the support plate can stably support the back plate on the workbench. For details, refer to Figure 7 At this time, one end of the support plate 105 is supported on the workbench 20, and one end of the back plate 101 provided with the liquid storage groove is supported on the workbench, and because the included angle between the support plate and the workbench is a right angle or an obtuse angle, the support plate can stably support the back plate on the workbench.

[0064] The biggest feature of this support mode is that the structure is simple, the processing and molding are convenient, and the actual use requirements can be well met.

[0065] In some embodiments, referring to Figure 5 and Figure 6 The limiting piece is a limiting plate 106 integrally bent and formed on the upper end of the back plate. As Figure 5 The limiting plate 106 can be integrally bent and formed on the middle position of the upper end of the back plate, and the processing and molding of the limiting plate are convenient.

[0066] In some embodiments, referring to Figure 8 , Figure 9 andFigure 10 The support includes a set of bracket assemblies. The bracket assembly includes two telescopic brackets 107 disposed on the back of the back plate 101. The two telescopic brackets 107 are respectively located near the two sides of the back plate. One end of the telescopic bracket 107 is hinged to the back plate 101. In this embodiment, the hinge connection between the telescopic bracket and the back plate is located at the upper end of the back plate.

[0067] The hinged connection between the telescopic bracket 107 and the back plate can be achieved using the aforementioned method of connecting the support plate and the back plate, which will not be elaborated further here. It should be noted that, while achieving the hinged connection between the telescopic bracket and the back plate, the hinged connection structure can create a certain rotational friction between the hinged portion of the telescopic bracket and the hinged portion of the back plate. This forces the telescopic bracket to rotate only under a certain force, thus limiting its rotation and ensuring stable support for the back plate when it is being supported.

[0068] The telescopic bracket 107 can adopt a telescopic structure similar to an antenna to facilitate the adjustment of the length of the telescopic bracket and realize arbitrary adjustment of the tilt angle of the back plate.

[0069] Correspondingly, the telescopic bracket and the back plate can also be hinged using a universal ball joint, giving the telescopic bracket greater rotational freedom to meet support requirements under different conditions.

[0070] In some embodiments, unlike the above embodiments, the support assembly in the brain cotton pad placement rack of this embodiment is located in the middle of the back plate.

[0071] Reference Figure 11 , Figure 12 and Figure 13 As shown, when the placement frame is suspended on the operating table by a hanging rope or rubber band, the backboard rests against the side of the operating table in the vertical direction under the action of gravity. At this time, the backboard can be supported by a telescopic bracket so that the backboard can be tilted, so that the brain cotton pad 30 on the backboard can be better presented in the surgeon's field of vision, making it convenient for the surgeon to take the brain cotton pad 30.

[0072] Reference Figure 14 This is another embodiment of the support unit on the shelf. In this embodiment, the support unit includes two sets of support assemblies, which are respectively located at the upper and middle parts of the back panel. When the support assembly located at the upper part of the back panel is needed, the angles of the two telescopic brackets of this set of support assemblies can be adjusted individually, and the other set of support assemblies will remain flush with the back panel without affecting the support. When the support assembly located in the middle of the back panel is needed, the angles of the two telescopic brackets of this set of support assemblies can be adjusted individually, further expanding the usage requirements of the shelf in different application scenarios.

[0073] The brain cotton sheet rack is used to hold various forms of gelatin sponge and brain cotton sheet. The various specifications of gelatin sponge and brain cotton sheet soaked in physiological saline can be well adsorbed on the working surface of the back plate and will not slide off. The physiological saline seeping out of the gelatin sponge and brain cotton sheet can flow into the liquid storage tank, avoiding the physiological saline from wetting the workbench or the sterile surgical drape.

[0074] During the operation, the rack is placed around the operation area. The surgeon can take the required specification of gelatin sponge and brain cotton sheet on the rack according to the needs. Since the working surface of the back plate is set as a smooth surface, there is no shielding structure in the area of the back plate for placing gelatin sponge and brain cotton sheet, which will not cause any shielding to the gelatin sponge and brain cotton sheet placed on the back plate, and will not cause any shielding and obstacles to the taking operation of the surgeon. This facilitates the precise taking of gelatin sponge and brain cotton sheet by the surgeon in the microsurgical operation, and improves the efficiency of the operation.

[0075] During the operation, the nurse can also supplement the consumed gelatin sponge and brain cotton sheet on the rack in a timely manner according to the needs, which is convenient to operate.

[0076] In some embodiments, based on the structural characteristics of the above brain cotton sheet rack, a combined rack for holding gelatin sponge and brain cotton sheet is also involved, referring to Figure 15 and Figure 16 , comprising:

[0077] The first rack 11 comprises a back plate 101 and a liquid storage tank 102 provided at the lower end of the back plate and having an opening at one end. The working surface 111 of the back plate for placing gelatin sponge and brain cotton sheet is a smooth surface.

[0078] The second rack 11 comprises a back plate 101 and a liquid storage tank 102 provided at the lower end of the back plate and having an opening at one end. The working surface 111 of the back plate for placing gelatin sponge and brain cotton sheet is a smooth surface. The upper end of the back plate of the second rack is hinged between the opening end of the liquid storage tank of the first rack.

[0079] A support portion is provided at the upper end of the back plate of the first rack 11. The support portion is used to support the upper end of the back plate of the first rack. When the first rack is placed on a plane, the working surface of the first rack can be inclined downward toward the direction of the liquid storage tank under the support of the support portion.

[0080] This combined rack is composed of two racks with basically the same structure. By setting the connection structure between the two racks, when the two racks are unfolded, referring to Figure 15, can form two working surfaces arranged in a row on the workbench, and the size of the working surface that can be used is expanded; in use, brain cotton pieces can be placed on the working surface of one placement rack, and gelatin sponges can be placed on the working surface of another placement rack, or different specifications of gelatin sponges and brain cotton pieces can be placed on the working surfaces of different placement racks, so that the operation of the surgery is further facilitated. Figure 16 When not in use, the two placement racks can be folded and stored to form a box structure that only occupies the size of one placement rack, facilitating storage of the combined placement rack, and effectively protecting the working surface of the back plate of the placement rack.

[0081] As shown in Figure 15 , when the combined placement rack is in an unfolded placement state, the first placement rack is supported on the workbench in an inclined manner through the support plate; the upper end of the back plate of the second placement rack is supported by the liquid storage tank of the first placement rack, and the other end is supported on the workbench and is also arranged on the workbench in an inclined manner; at this time, the combined placement rack forms two working surfaces arranged in a row on the workbench.

[0082] On the combined placement rack, for example, a magnetic attraction can be arranged at the bottom of the liquid storage tank, and the magnetic attraction arranged at the bottom of the first placement rack exerts a force between the first placement rack and the second placement rack, so that the first placement rack and the second placement rack can be well maintained in the unfolded state; and in the storage state, the magnetic attraction arranged at the bottom of the second placement rack exerts a force between the first placement rack and the second placement rack, so that the first placement rack and the second placement rack can be well maintained in the storage state.

[0083] Here, the hinge structure between the back plate of the second placement rack and the liquid storage tank of the first placement rack and the forming method can adopt a structure and forming method similar to that of the hinge between the back plate and the support plate.

[0084] The forming method of the first placement rack and the second placement rack, the connection structure and connection method between the liquid storage tank and the back plate, and the structure adopted by the support part can adopt the implementation method adopted in the above brain cotton piece placement rack, which will not be described here.
