Abstract
Description
Technical Field
[0001] This invention relates to the field of medical devices, and more particularly to a shoulder support and anti-slip positioning device for thyroid surgery. Background Technology
[0002] Thyroid surgery usually requires patients to maintain a hyperextended neck position. Medical staff need to place a support under the patient's shoulders and back to provide local support and expose the operative field of the neck incision. During the operation, it is usually necessary to adjust the angle of the operating table. The patient's center of gravity loses horizontal support and faces the risk of sliding downward.
[0003] Conventional anti-slip methods often use ordinary cloth straps to bind and connect across the patient's shoulders. The locking structure at the end of the existing cloth straps mostly relies on interlacing and knotting or on surface friction to lock, lacking a dedicated rigid insertion and extraction locking mechanism. The interlacing and tightening steps during the preoperative preparation stage are cumbersome and time-consuming for medical staff. In case of an emergency that requires the shoulder restraint to be released, the fasteners, which are under tension, are difficult to quickly disassemble. At the same time, the connection nodes of conventional fasteners are prone to loosening and slippage under the continuous pull of the patient's gravity.
[0004] Therefore, this invention proposes a shoulder support and anti-slip positioning fixation device for thyroid surgery to overcome the shortcomings of the prior art. Summary of the Invention
[0005] In view of the problems existing in the present technology of shoulder support and anti-slip positioning fixation device during thyroid surgery, such as the lack of rigid locking structure at the end of the traditional flexible strap, the cumbersome and time-consuming preoperative tightening procedure, and the difficulty in timely loosening of the tight fasteners when the shoulder restraint needs to be disassembled and released in an emergency, the present invention provides a shoulder support and anti-slip positioning fixation device during thyroid surgery with an improved structure that can effectively solve the above problems.
[0006] This invention provides a shoulder support and anti-slip positioning fixation device for thyroid surgery, including a base, a support pad fixedly connected to the top side plane of the base, an elastic band on the support pad, and a fixing mechanism installed on the surface of the support pad. The fixing mechanism includes a strap and a limiting component. The strap is fixedly connected to one edge of the support pad, and the limiting component includes a card seat and a card slot. The bottom end face of the card seat is fixedly connected to the strap.
[0007] The telescopic belt is fixedly connected to a pin, the top surface of the pin is rotatably connected to a connecting rod, the end of the connecting rod is rotatably connected to a connecting block, the bottom surface of the connecting block is fixedly connected to a spring, the bottom end of the spring is fixedly connected to the top surface of the pin, and a slot is opened on the top side surface of the card seat.
[0008] Furthermore, the front end of the pin slides into the cavity inside the card holder, and the side wall surface of the connecting block abuts against the inner side wall of the card slot, forming a pressure-linked contraction connection between the pin and the card holder.
[0009] The bottom surface of the connecting block is fixedly connected to the top of the spring, and the connecting block provides a bottom mounting surface by utilizing its own lateral protruding structure.
[0010] The end of the connecting rod is rotatably connected to the vertical side wall of the connecting block, and the end of the connecting rod forms an eccentric force-bearing downward rotation avoidance connection structure.
[0011] The front end of the card slot has a through-hole for insertion, which provides a channel for directional insertion and docking.
[0012] The front end of the pin slides into the insertion opening, and the pin slides in a directional manner into the card holder along the notch on the open surface.
[0013] The bottom end face of the card slot is vertically connected to the cavity inside the card holder, and the upper part of the card holder exposes the internal space for accommodating and fitting.
[0014] The spring is vertically supported on the top surface of the pin, and the spring provides a vertical upward counter-lifting support force.
[0015] The top surface of the support pad is recessed and has an arc-shaped positioning groove, and the inside of the arc-shaped positioning groove provides an inwardly recessed support contact surface.
[0016] The bottom surface of the support pad is fully attached to the top surface of the base, and the support pad uses an adhesive layer coated on the bottom surface to prevent lateral pressure slippage and misalignment at the bottom.
[0017] The present invention has the following beneficial effects: 1. In this invention, the pin, spring, and connecting block inside the fixing mechanism form a pressure-linked retraction structure. With the help of a slotted seat, the operator can push the pin into the cavity inside the seat by pressing the connecting block. After the external force is removed, the connecting block is automatically pushed up and locked into the slot under the support of the spring. During subsequent disassembly, pressing the connecting block again will pull the pin outward. The docking and locking are completed by the pressing and pulling structure, which shortens the operation time of fixing the patient's position before surgery and removing the restraint after surgery.
[0018] 2. In this invention, the surface of the support pad is formed with an arc-shaped contact surface that is concave downward in the middle. The surface shape conforms to the outer contour of the patient's shoulder and back. Together with the strap that spans across the patient's shoulder, it forms a closed-loop constraint space, which restricts the longitudinal slippage and misalignment of the patient's torso when the operating table is tilted or the neck is hyperextended, thus maintaining stable exposure of the local operating field during thyroid surgery.
[0019] 3. In this invention, the two ends of the connecting rod at the top of the pin are rotatably connected to the pin and the surface of the connecting block, respectively. After the connecting block is reset and embedded in the slot, the outer sidewall of the connecting block is attached to the periphery of the inner sidewall of the slot. The lateral tension generated by the strap being pulled by external force is directly blocked and borne by the end face of the card seat, so as to avoid the strap being stretched and taut and the insertion part accidentally coming out, thus ensuring the tensile strength of the connection node in the locked state.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example: Please refer to Figures 1 to 4 This invention provides a shoulder support and anti-slip positioning device for thyroid surgery, which solves the problem that the shoulder slides downward due to the lack of a matching constraint and limiting structure in the positioning pads used in thyroid surgery. The shoulder support and anti-slip positioning device for thyroid surgery includes a base 1 and a support pad 2 fixedly connected to the top side plane of the base 1. The base 1 is used to support the upper components, and the support pad 2 is used to elevate and support the patient's shoulder and back. A fixing mechanism 3 is installed on the surface of the support pad 2. The fixing mechanism 3 is used to cross the patient's surface for anti-slip constraint and quick locking.
[0024] The fixing mechanism 3 includes a strap 31 and a limiting component 36. The strap 31 is used to fit and wrap the surface of the human shoulder. The fixed end of the strap 31 is fixedly connected to the edge of one side of the support pad 2. The movable end of the strap 31 is detachably equipped with a pin 32. The pin 32 is used to provide a rigid docking guide end. The top surface of the pin 32 is rotatably connected to a connecting rod 33. The connecting rod 33 is used to deflect under pressure and transmit downward pressure. The end of the connecting rod 33 is rotatably connected to a connecting block 34. The connecting block 34 is used to descend under pressure to avoid it and float up after releasing the force to form a limit. The bottom surface of the connecting block 34 is fixedly connected to a spring 35. The spring 35 is used to store energy under pressure and provide an elastic restoring force to push the connecting block 34 upward. The bottom end of the spring 35 is fixedly connected to the top surface of the pin 32, forming a pressure-linked contraction structure.
[0025] The limiting component 36 includes a card holder 361 and a card slot 362. The card holder 361 is used to provide space for docking and covering the outer shell. The right end face of the card holder 361 is fixedly connected to the strap 31. The card slot 362 is provided on the top side surface of the card holder 361. The card slot 362 is used for the connection block 34 to be inserted after reset. The front end of the pin 32 is slidably inserted into the cavity inside the card holder 361. At this time, the side wall surface of the connection block 34 abuts against the inner side wall of the card slot 362, and the surface interference prevents the pin 32 from sliding outward and being pulled out.
[0026] The bottom surface of the connecting block 34 is fixedly connected to the top of the spring 35. The entire side wall of the spring 35 is vertically supported on the top surface of the pin 32, providing an upward reverse support force. The end of the connecting rod 33 is rotatably connected to the vertical side wall of the connecting block 34, forming an eccentric force-pressing structure. When the operator presses the top surface of the connecting block 34 and moves it downward, the end of the connecting rod 33 is forced to rotate downward around the pivot point, and the connecting block 34 compresses the bottom spring 35, causing it to contract and deform.
[0027] The card holder 361 has a hollow space inside to accommodate the docking components. The front end of the card holder 361 has a through-hole for insertion opening, which provides a docking channel for the front end to enter. The card slot 362 is opened on the top of the card holder 361, and the front end of the pin 32 is slidably inserted into the insertion opening.
[0028] The outer edge size of the connecting block 34 is adapted to the inner contour size of the slot 362. After the pin 32 with the connecting block 34 in the pressed state is fully pushed into the internal space of the slot 361, the external pressing force is released. The connecting block 34 loses the external pressing force and is pushed upward and reset under the action of the spring 35's own reverse elastic restoring force. After reset, the outer surface of the connecting block 34 tightly abuts against the periphery of the inner side wall of the slot 362. The pin 32 is blocked from retracting outward by the contacting side edges, thus completing the component docking and locking.
[0029] The working principle is as follows: Medical staff place the patient's shoulder and back on the recessed area of the support pad 2 fixedly connected above the base 1, pull the telescopic strap 4 to cover the surface of the patient's shoulder, and the operator presses the surface of the connecting block 34 at the top of the pin 32 with their fingers and applies downward pressure. The connecting block 34 drives the connecting rod 33, which is rotated at its end, to rotate around the top surface of the pin 32. Simultaneously, the bottom surface of the connecting block 34 presses down on the spring 35. The spring 35 is compressed and deformed to store energy. Then, the retaining seat 361 inside the limiting component 36 is pulled to cover the surface of the patient's shoulder. The right end of the retaining seat 361 is fixed to the strap 31. The operator holds... With the pin 32 in the pressed position and its front end aligned with the open area at the front end of the card holder 361, push the pin 32 to slide into the internal cavity of the card holder 361. When the connecting block 34 moves with the pin 32 to the position directly below the card slot 362 at the top of the card holder 361, the operator releases their finger to release the external pressing pressure. Under the upward and reverse elastic restoring force released by the spring 35, the connecting block 34 is pushed upward and locked into the inside of the card slot 362. The outer wall of the connecting block 34 is tightly abutted against the inner wall of the card slot 362, using the side contact to prevent the pin 32 from retracting outward, thus completing the entire insertion and locking process of the fixing mechanism 3.
[0030] When the surface fixation constraint needs to be released after the procedure, the operator presses down on the top surface of the connecting block 34 exposed inside the slot 362 with their fingers. The connecting block 34 moves downward under pressure, compressing the spring 35. The side of the connecting block 34 completely disengages from the blocking area of the inner edge side wall of the slot 362, and pulls the telescopic belt 4 outward, causing the pin 32 to exit outward, thus releasing the constraint state of the telescopic belt 4 and the strap 31.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
