Description

Technical Field

[0001] This utility model relates to a positioning aid for spinal surgery, specifically a hand support that can adjust the support of both upper limbs in a prone position, avoid brachial plexus injury, and ensure surgical field exposure. Background Technology

[0002] During spinal surgery, the patient is usually placed in a prone position with the upper arms typically positioned on either side of the head and neck in a prone position. Since spinal surgery is generally lengthy, especially spinal correction surgery which typically lasts 4-6 hours, the angle between the upper arm and the thoracic cavity is often greater than 90 degrees for an extended period. This can cause traction damage to the brachial plexus, leading to postoperative postoperative positional complications and discomfort for the patient. Furthermore, using the handrests that come with the operating table can significantly hinder the surgeon's positioning and operation, making the procedure more difficult.

[0003] The existing operating table comes with a fixed hand support board, which often results in an upper arm abduction angle greater than 90°. Prolonged traction can easily damage the brachial plexus. The hand support board occupies lateral space, hindering the surgeon's standing position and instrument access. The existing movable hand support device can only be adjusted horizontally or vertically, and cannot simultaneously achieve multi-dimensional individualized adjustments such as abduction angle, height, proximal and distal angles, and pronation-supination. There is no dedicated locking structure, requiring additional straps for fixation, resulting in poor stability and easy displacement during surgery.

[0004] Patent application number CN202022826219.0 relates to a spinal surgery support, belonging to the field of medical device technology. It addresses the problem of existing technologies being unable to perform fluoroscopic surgery at the end of the operating table, and the high cost of equipment. The support includes a spinal system main body, a body frame, and a facial support, with the body frame and facial support sequentially connected to the spinal system main body. It eliminates the need to purchase a dedicated spinal surgery table, reducing equipment costs for hospitals; it is adaptable to different body types (weight, height, etc.), and the panel height can be adjusted via a locking handle to accommodate different patient height requirements in prone positions; the body frame is made of fiberboard suitable for X-ray fluoroscopy, so there are no metal components obstructing spinal fluoroscopy.

[0005] However, the aforementioned patented technology does not solve the technical problems existing in the prior art, nor does it provide any inspiration for solving these problems. Therefore, there is an urgent need for a prone arm support that can be quickly installed on any operating table and allows for multi-dimensional individualized adjustment. Utility Model Content

[0006] The purpose of this utility model is to provide a prone support for spinal surgery to solve the problems mentioned in the background art.

[0007] (1) How to achieve an upper arm abduction angle of ≤90° for patients undergoing spinal surgery, with the distal joint always lower than the proximal joint; (2) How to achieve quick installation of the arm support frame without the need for straps, and without displacement during surgery.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A prone support for spinal surgery;

[0010] Includes a handle plate, clamping assembly, adjustment assembly, and rotating assembly.

[0011] The clamping assembly includes a clamping seat, and the right side wall of the clamping seat has a clamping groove for accommodating the operating table's built-in bed support board. The clamping groove extends to the front and rear end faces of the clamping seat. The upper right side wall edge of the clamping groove extends downward to a locking platform. The clamping seat also has a clamping hole, which communicates with the clamping groove and penetrates the upper and lower end faces of the clamping seat.

[0012] The adjustment assembly includes a clamping plate, a horizontal bar, and a vertical bar. The upper end of the clamping plate passes through the clamping hole of the clamping seat, and the lower end of the clamping plate is fixedly connected to the end of the horizontal bar. The horizontal bar and the vertical bar are connected.

[0013] The rotating assembly includes a universal ball joint, the outer shell of which is fixedly connected to the upper end of the vertical rod, and the ball head of which is fixedly connected to the handle plate.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the clamping assembly also includes a clamping bolt, the end of which is threaded into the clamping seat and extends into the clamping groove.

[0016] Furthermore, the adjustment assembly also includes a horizontal sleeve and a vertical sleeve. The outer wall of the horizontal sleeve is fixedly connected to the outer wall of the vertical sleeve. The horizontal sleeve is fitted onto the horizontal bar, and the vertical sleeve is fitted onto the vertical bar.

[0017] Furthermore, the adjustment assembly also includes a horizontal adjustment bolt and a vertical adjustment bolt. The side wall of the horizontal sleeve has a threaded hole, and the horizontal adjustment bolt passes through the threaded hole in the side wall of the horizontal sleeve, with the end of the horizontal adjustment bolt abutting against the outer wall of the crossbar.

[0018] The vertical sleeve has a threaded hole on its side wall, and the vertical adjusting bolt passes through the threaded hole on the side wall of the vertical sleeve, with the end of the vertical adjusting bolt abutting against the outer wall of the vertical rod.

[0019] Furthermore, the ball joint of the rotating assembly is fixedly connected to the handle plate via a connecting rod.

[0020] Furthermore, the length of the clamping hole is the same as the width of the clamping plate, and the width of the clamping hole is longer than the thickness of the clamping plate.

[0021] This prone arm support for spinal surgery addresses the issue of patients' arms having an abduction angle greater than 90 degrees when in the prone position, while also preventing interference with the surgeon's operation. The clamping components can be fixed to the armrest board of any operating table, and the distance between the armrest board and the bed can be adjusted arbitrarily. The abduction angle of the armrest board can also be adjusted, conforming to the principle of the prone positioning guidelines that the distal joint end should be lower than the proximal joint end.

[0022] The beneficial effects of this prone support arm for spinal surgery are:

[0023] (1) Neuroprotection: abduction angle ≤90°, distal lower than proximal, reduces the incidence of brachial plexus injury by >80% after surgery;

[0024] (2) The surgical field of view is unobstructed, the hand support board can be retracted horizontally to the edge of the bed, and the surgeon's standing position and C-arm fluoroscopy are unobstructed.

[0025] (3) Multidimensional precise adjustment, 5 degrees of freedom + degree locking, suitable for patients of different body types;

[0026] (4) Quick loading and unloading, with a slot and table structure, installation can be completed by one person in 30 seconds;

[0027] (5) Applicable to any operating table with a handrail or bed rail, no additional accessories required. Attached Figure Description
