Description

Technical Field

[0001] The utility model relates to the technical field of surgical beds and instruments, and in particular to an upper limb interventional surgery arm support and an operating bed. Background Art

[0002] Upper limb arterial or venous diseases, such as arteriosclerosis, thrombosis, and hemangioma, can cause symptoms such as upper limb pain, numbness, swelling, and skin color changes, which seriously affect the patient's quality of life. Upper limb interventional surgery is a minimally invasive treatment for upper limb vascular diseases. It repairs or improves the vascular structure and restores blood flow by performing surgical operations inside the blood vessels, thereby alleviating or eliminating symptoms. During the operation, the patient lies flat on the surgical wound after anesthesia, with the palm facing up and the arm placed naturally. The doctor uses special catheters and instruments to enter the blood vessels through radial artery puncture or incision, and then performs operations inside the blood vessels, such as dilating narrowed blood vessels, removing blood clots, and repairing hemangiomas.

[0003] At present, the operating beds in hospitals are all purchased in a centralized manner and are suitable for a variety of surgeries. After lying down on the beds, it is inconvenient for doctors to operate if the upper limbs are placed on the bed. For upper limb interventional surgeries, a small mobile table needs to be placed under the patient's arms on the operating side to facilitate the operation. However, the small table has large legs and a large tabletop size, which affects the doctor's standing position and makes it inconvenient for the doctor to operate.

[0004] There are also some similar expansion brackets that are clamped on the hospital bed, such as the patent document with application number 202220228769.9, which discloses an arm bracket for interventional surgery, including a mounting table, an arm bracket, a groove, a pin, a clamp, a clamping bolt, a clamping plate, a rotating rod, and an arc groove. The mounting table is provided with a groove, and a pin is provided in the groove. One end of the arm bracket is connected to the mounting table through a pin, and the mounting table is fixedly connected to the clamp. A clamping bolt is provided on the upper surface of the clamp, a clamping plate is provided at one end of the clamping bolt, and a rotating rod is provided at the other end of the clamping bolt. The arm bracket is provided with an arc groove adapted to the human arm. It has the following disadvantages: first, a clamping bolt is provided on the upper surface of the clamp, a clamping plate is provided at one end of the clamping bolt, and a rotating rod is provided at the other end of the clamping bolt. The clamp is used by rotating the clamping bolt to clamp the clamp on the edge of the operating table. This fixing method is point fixing, with a small contact surface and instability, and the rotating rod is on top, which affects the laying of sterile sheets on the operating table. The patient lying on it also affects the doctor's rotation operation; second, the arm bracket is fixed in size, which is not universal for patients of different physiques and different fat and thin bodies; third, it needs to be used repeatedly. Although a sterile sheet is laid, the sterile sheet needs to be cut according to the situation. The sterile sheet is easy to penetrate, inconvenient to disinfect, and cannot be replaced for each patient. Utility Model Content
