Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical protective equipment processing equipment, specifically a heat sealing device for disposable surgical microscope covers. Background Technology
[0002] Medical microscopes are frequently used to assist in surgical procedures. To prevent cross-infection and achieve aseptic isolation, sterile protective sleeves are used to protect the microscope. These sleeves are known as surgical microscope protective sleeves. Commonly available surgical microscope protective sleeves typically consist of two parts: a polyethylene film cover and a polyethylene microscope connecting sleeve. Traditionally, the polyethylene film cover and connecting sleeve are bonded together using adhesive to create a single integrated structure. During use, the connecting sleeve is quickly inserted into the microscope head, ensuring a sterile environment at the surgical site. The sleeve is also easily removed after surgery, offering advantages such as convenience, cleanliness, reduced workload for medical staff, and significantly improved operational efficiency.
[0003] While such products are convenient and simple to use, they involve complex processing. Aside from the cutting of the polyethylene film cover, the process of attaching the polyethylene film cover to the microscope connecting sleeve is time-consuming and tedious. First, positioning marks must be made on the polyethylene film cover before applying adhesive and bonding it to the microscope connecting sleeve. After bonding, it needs time to dry before being folded and packed into a box. Furthermore, the durability is not very good, and the pass rate is unstable. Therefore, a disposable surgical microscope sleeve heat-sealing device is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-7In this embodiment of the invention, a disposable surgical microscope sleeve heat sealing device includes a fixed upright plate 1. A reinforcing rib plate 17 is installed on the back of the fixed upright plate 1. A cylinder plate 2 is provided at the upper end of the fixed upright plate 1. The cylinder plate 2 is fastened to the fixed upright plate 1 by multiple bolts. A reinforcing rib 12 is provided on the lower surface of the cylinder plate 2. The number of reinforcing ribs 12 is not limited. In this embodiment, preferably, there are two reinforcing ribs 12, each located on the lower surface of the cylinder plate 2 near both sides, to improve the working strength and stability of the cylinder plate 2 when the power cylinder 3 is activated. Furthermore, a reinforcing angle bracket 14 is provided at the connection between the cylinder plate 2 and the fixed upright plate 1. The reinforcing angle bracket 14 is connected to the fixed upright plate 1 and the cylinder plate 2 by multiple bolts, reinforcing the connection between the fixed upright plate 1 and the cylinder plate 2. The triangular fastening principle ensures the stability coefficient of the device during operation. A reinforcing rib plate 17 is fixed on the cylinder plate 2. Equipped with a power cylinder 3, the end of the power cylinder 3 is provided with an upper mold mechanism 7 located below the cylinder plate 2. The upper mold mechanism 7 is driven by the power cylinder 3 to move up and down, thereby completing the heat sealing process of the surgical microscope sleeve. A heat sealing suspension 4 is provided on the fixed upright plate 1 located below the cylinder plate 2. The heat sealing suspension 4 reduces the difficulty of sleeve covering. The heat sealing suspension 4 is arranged parallel to the bottom of the cylinder plate 2. A positioning tooling mechanism 5 is provided on the heat sealing suspension 4 located below the upper mold mechanism 7. The heat sealing suspension 4 serves to support the positioning tooling mechanism 5. At the connection between the heat sealing suspension 4 and the fixed upright plate 1, there are two support brackets 18. The lower surface of the heat sealing suspension 4 is provided with reinforcing ribs located between the two support brackets 18 to improve rigidity and strength and prevent breakage due to long-term pressure. The design of the support brackets 18 can provide a certain support force for the heat sealing suspension 4 to prevent deformation and instability.
[0027] The positioning fixture mechanism 5 includes a positioning fixture mold 51 and a positioning fixture base 52 connecting the positioning fixture mold 51 and the heat-sealing suspension 4. The positioning fixture mold 51 has a positioning groove 53, which is composed of four separate semi-circular arc plates used to fix the microscope sleeve ribs. The positioning fixture mold 51 and the positioning fixture base 52 are connected by a buffer spring 54. A buffer silicone pad 55 is attached to the end face of the positioning fixture base 52 adjacent to the positioning fixture mold 51, providing pressure buffering and mold closing compaction effects. The end face of component 2 is provided with a fixing stud 56. A fixing shaft 57 is threaded onto the outer surface of the fixing stud 56. The fixing shaft 57 has an internal thread groove. The external thread of the fixing stud 56 is adapted to the internal thread groove of the fixing shaft 57. The fixing stud 56 and the fixing shaft 57 can be fixed and removed by rotating the fixing shaft 57. A buffer spring 54 is sleeved on the outer circumferential surface of the fixing shaft 57. The two ends of the buffer spring 54 are respectively connected to the positioning fixture mold 51 and the positioning fixture base 52. The positioning fixture mold 51 and the positioning fixture base 52 are respectively connected to the positioning fixture mold 51 and the positioning fixture base 52. Both adjacent end faces are provided with inner grooves. The fixing stud 56 and the fixing shaft 57 are located in the inner grooves on the positioning fixture base 52. The fixing shaft 57 plays a positioning role for the buffer spring 54, while the buffer spring 54 mainly generates buffering force during the compression of the positioning fixture mold 51 and automatically adjusts the offset, so that the positioning fixture mold 51 is subjected to uniform force throughout the working process. The buffer spring 54 and the buffer silicone pad 55 achieve multiple buffering to complete the automatic alignment during the equipment processing, so that the force is uniform, thereby achieving... To achieve uniform heating, the positioning fixture mold 51 is equipped with multiple shoulder bolts that connect to the positioning fixture base 52. The ends of the shoulder bolts are externally threaded and connected to the positioning fixture base 52, while the middle is a smooth surface, ensuring that the positioning fixture mold 51 can move within the range of the smooth surface. The positioning fixture base 52 is provided with a waist-shaped groove 59, and a guide post inserted into the waist-shaped groove 59 is installed on the heat-sealing suspension 4. After the guide post and the waist-shaped groove 59 are combined, the position of the positioning fixture base 52 can be moved along the length direction of the waist-shaped groove 59.
[0028] Please see Figure 4 In one embodiment, preferably, the positioning tooling mold 51 is provided with a plurality of rotatable limiting blocks 58. After the polyethylene film cover and the microscope connecting sleeve are assembled, the rotatable limiting blocks 58 are rotated so that the lower surface of the rotatable limiting blocks 58 abuts against the upper part of the polyethylene film cover and the microscope connecting sleeve. Its main function is to prevent the microscope sleeve from being taken away by the heat sealing mold 74 due to the heat effect when the polyethylene film cover and the microscope connecting sleeve are heat-fused into one piece, thereby damaging the polyethylene film cover.
[0029] Please see Figure 1-2In one embodiment, preferably, sheet metal support frames 6 are symmetrically arranged on both sides of the heat-sealed suspension 4, and the positioning fixture mechanism 5 is located between the two sheet metal support frames 6. The upper surfaces of the two sheet metal support frames 6 are on the same horizontal plane, and the upper surface of the sheet metal support frame 6 is higher than the upper end of the positioning fixture mechanism 5. The two sheet metal support frames 6 can ensure that the polyethylene bag can be placed stably and naturally during operation, and will not produce an unbalanced state due to the lack of a support point.
[0030] Please see Figure 1 In one embodiment, preferably, the lower end of the fixed upright plate 1 is provided with a base frame 8, and the upper surface of the base frame 8 is provided with a base plate 9 on the side adjacent to the fixed upright plate 1. Horizontal adjustment wheels 10 are installed at the four corners of the lower surface of the base frame 8 to facilitate machine relocation and maintenance. The base plates 9 are all located on the side of the base frame 8 close to the fixed upright plate 1, and no other parts are provided. This design can reduce the weight of the whole machine and also place the control foot pedal in an open space for easy operation by personnel.
[0031] Please see Figure 1 In one embodiment, preferably, an electrical control box 11 is installed on the fixed upright plate 1. The operation panel of the electrical control box 11 is located on the front of the electrical control box 11 for easy operation by personnel. A cylinder cover 13 is provided on the cylinder plate 2, wherein the power cylinder 3, the limit rod 15 and the linear bearing 16 are all located inside the cylinder cover 13, which plays a role in safety protection and sound insulation, and neatly hides the exposed air passages and wiring inside, making the whole machine more concise and beautiful.
[0032] Please see Figure 3 In one embodiment, preferably, the cylinder plate 2 is provided with a limiting light rod 15 extending from the top of the cylinder plate 2 to the bottom of the cylinder plate 2. A linear bearing 16 connected to the cylinder plate 2 is provided on the outer surface of the limiting light rod 15. The end of the limiting light rod 15 is connected to the upper mold mechanism 7 through a positioning block 19, which plays a role in preventing the upper mold mechanism 7 from rotating axially during the heat sealing process. The design of the linear bearing 16 can reduce the contact between the limiting light rod 15 and the cylinder plate 2, thereby reducing the wear caused by the relative movement of the two. Secondly, the limiting light rod 15 can restrict the extension and retraction end of the cylinder plate 2, keeping it in a vertical lifting state.
[0033] Please see Figure 2 In one embodiment, preferably, the upper mold mechanism 7 includes a cylinder connector 71, which is connected to the end of the power cylinder 3 via a limiting nut 72. The positional distance between the cylinder connector 71 and the power cylinder 3 can be adjusted. A high-temperature heat insulation plate 73 is installed at the end of the cylinder connector 71 away from the limiting nut 72, and a heat sealing mold 74 is provided below the high-temperature heat insulation plate 73.
