Description

Technical Field

[0001] The utility model relates to an operating table, in particular to a multifunctional operating table for neurology or neurosurgery and other surgeries in an interventional catheterization room, belonging to the technical field of medical auxiliary equipment. Background Technique

[0002] In the modern medical system, the complexity and diversity of interventional surgeries are increasing continuously, which requires surgical equipment to have high adaptability and versatility. The design of the operating table is crucial for optimizing the surgical process and patient safety. There are usually multiple operating tables in the interventional catheterization room to meet the surgical needs of different departments. However, the current elevated operating tables for neurology or neurosurgery and other surgeries in the interventional catheterization room often have certain limitations, especially in terms of space sharing and emergency surgical treatment. When performing neurology or neurosurgery and other surgeries in the interventional catheterization room, a special elevated operating table needs to be installed at the end of the operating bed corresponding to the position above the patient's legs to hold various surgical supplies such as catheters and guidewires required for the surgery and provide a platform for the surgeon to perform interventional surgery. However, the installation and use of this special elevated operating table are relatively troublesome. It is necessary to first carry the supporting frame to the end of the operating bed, then carry the platform board and install it on the frame, and then carry the infusion stand and tighten it at the end of the bed. Moreover, since this elevated operating table cannot be directly stored on the operating bed, in order to facilitate other departments to use the operating bed for other surgeries during non-use periods, this elevated operating table needs to be completely removed and moved away. And when there is an emergency neurology or neurosurgery operation, it needs to be reinstalled urgently, which not only increases the surgical preparation time but also may affect the timely execution of emergency surgeries. Content of the Utility Model

[0003] The purpose of the utility model is to provide a multifunctional operating table for an interventional catheterization room, which is used for neurology or neurosurgery and other surgeries. It can be directly stored on the operating bed during non-use periods without affecting the progress of other surgeries, and there is no need to repeatedly remove and install it. Moreover, this operating table also integrates various necessary functions, which can reduce the surgical preparation time and improve the surgical efficiency.

[0004] The specific technical solutions adopted by the utility model are as follows:

[0005] An interventional catheterization room multi-functional operating table is provided with a horizontally arranged rectangular main tabletop. A liftable support is provided below the main tabletop to support it. A movable tabletop that can slide leftward and extend out as an extension board of the main tabletop is stacked above the middle and left side of the main tabletop. Above the right side of the main tabletop, a foldable infusion rack is erected near the rear edge of the tabletop. The infusion rack is installed on the main tabletop through a foldable and expandable right-angled triangular support. When the infusion rack is expanded, it stands upright at the right corner of the rear edge of the main tabletop. When the infusion rack is folded, it tilts forward to be parallel to the main tabletop and stacked on the main tabletop.

[0006] The liftable support is provided with a rectangular bottom frame. The bottom frame is connected to the bottom surface of the main tabletop through a scissor mechanism composed of two right-leaning connecting rods arranged in parallel front and back and two left-leaning connecting rods arranged in parallel front and back and cross-hinged. The upper ends of the two right-leaning connecting rods are respectively hinged on two upper hinge seats fixedly installed on the right side of the bottom surface of the main tabletop front and back. The lower ends of the two right-leaning connecting rods are jointly hinged on the rod body of the same horizontal longitudinal sliding rod. On the left side inside the bottom frame, a pair of horizontally arranged sliding grooves with opposite openings are fixedly connected along the inner edges of the front and back side frames of the bottom frame. The front and rear ends of the sliding rod are respectively slidably placed in the front and rear sliding grooves, so that the sliding rod can slide left and right along the sliding grooves. The lower ends of the two left-leaning connecting rods are respectively hinged on two lower hinge seats fixedly connected to the inner edge of the right side frame of the bottom frame front and back. At the intersection of the two left-leaning connecting rods and the two right-leaning connecting rods in the middle, there is a hinge pin that penetrates both the left-leaning connecting rod and the right-leaning connecting rod at the same time. The upper ends of the two left-leaning connecting rods are jointly hinged on the rod body of the same horizontal longitudinal sliding rod. On the left side of the bottom surface of the main tabletop, a pair of horizontally arranged sliding grooves with opposite openings are fixedly connected front and back. The front and rear ends of the sliding rod are respectively slidably placed in the front and rear sliding grooves, so that the sliding rod can slide left and right along the sliding grooves. The middle of the sliding rod is also fixedly connected to the seat body of a horizontally arranged air spring. On the bottom surface of the main tabletop at the left side of the air spring, a fixed seat is fixedly connected. The core rod of the air spring extends leftward and is fixedly connected to the fixed seat. An unlocking handle for controlling the unlocking of the air spring is also installed on the fixed seat. The lifting height of the entire scissor mechanism is locked by the air spring.

[0007] This multifunctional operating table for the interventional catheterization laboratory is placed at the foot of the operating bed. When in use, its infusion stand is unfolded and the tabletop is lifted to a suitable height. Then, interventional surgeries such as those in neurology or neurosurgery can be performed on this platform. At the same time, various infusion devices required during the surgery can be hung. During non-use periods, it can be folded and stored flat at the foot of the operating bed without affecting the progress of other surgeries and without the need for repeated removal and installation. Therefore, using this multifunctional operating table can reduce the need for frequent replacement of the operating table or equipment, thereby reducing the surgical preparation time and the interruption time during the surgery. This not only improves the surgical efficiency but also reduces the risk of misoperation caused by operating complex equipment. Moreover, due to its multifunctional characteristics, using this multifunctional operating table can reduce the number of equipment configurations and space occupancy in the catheterization laboratory operating room, simplify the layout of the catheterization laboratory operating room, enabling medical institutions to configure their resources more flexibly and improve the operating efficiency of the catheterization laboratory.
