Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a PFNA surgical arm fixation device. Background Technology

[0002] PFNA is a novel proximal femoral internal fixation system, which is a newly improved PFN (proximal femoral intramedullary nail) system. On the one hand, it inherits the advantages of the original PFN and has the same biomechanical characteristics. On the other hand, it has made innovations in specific design, making fixation more effective and operation simpler.

[0003] Among these factors, the surgical positioning is crucial for the smooth conduct of the surgery and the patient's comfort. Please refer to [link / reference]. Figure 1 As shown, during PFNA surgery, the body needs to be in a specific position. In this position, the forearm on the same side as the affected limb needs to be suspended horizontally perpendicular to the spine to fully expose the affected area and avoid interference from the arm on the same side of the affected limb during the surgery. Currently, the most common method is to fix an inverted "L"-shaped support rod 7 next to the operating table 8, and then tie the corresponding forearm to the support rod 7.

[0004] In existing technology, medical staff use an abdominal binder and cotton pads to immobilize the patient's forearm. For details, please refer to [link / reference needed]. Figure 2 As shown, medical staff attach several abdominal binders 9 together to form a long, narrow support belt. Then, one medical staff member supports the patient's forearm on the support rod 7 using a cotton pad. Another medical staff member uses the support belt to wrap around the patient's forearm and the support rod 7 from left to right, forming a loop structure with openings at the top and bottom; then, another abdominal binder 9 is wrapped around the loop structure from top to bottom, thus securing the cotton pad and the patient's forearm within the loop structure.

[0005] This method requires at least two medical staff to work together to immobilize the patient's forearm, making it difficult to operate and inefficient. Furthermore, the abdominal binder and homemade cotton pad used are common postural fixation devices without special properties. For thin or elderly patients, this can lead to insecure fixation, skin pressure, and even nerve damage. It also hinders the relaxation of upper limb muscles and ligaments and impedes venous return.

[0061] Furthermore, to ensure the hygiene of the second side of the fixation strap 1, a replaceable lining (not shown in the figure) is provided on the second side of the fixation strap 1, which comes into contact with the patient's forearm. This replaceable lining is detachably connected to the fixation strap 1 via Velcro. The hygiene of the second side of the fixation strap 1 is ensured by replacing the replaceable lining.

[0062] In this embodiment, there are two winding strips 2, located at the same opening edge of the sleeve, that is, the two winding strips 2 are set on the same side.

[0063] Furthermore, in order to ensure that the winding tape 2 can be effectively wound around the sleeve and close the openings at both ends of the sleeve, the length of the winding tape 2 is greater than the length of the sleeve.

[0064] Furthermore, to ensure that the fixing strap 1 can effectively form a sleeve, the second connector 4 is disposed near the edge of the fixing strap 1 and extends along the length direction of the sleeve. There are at least two first connectors 3, which are spaced apart along the length direction of the sleeve.

[0065] In this embodiment, there are three first connectors 3, which are spaced apart along the length of the sleeve.

[0066] Furthermore, the length direction of the first connector 3 is perpendicular to the length direction of the second connector 4.

[0067] Further, please refer to Figure 4As shown, the first end of the wrapping tape 2 is provided with a fourth connector 6. The fourth connector 6 is located on the first surface of the wrapping tape 2, or on the second surface of the wrapping tape 2, or on both the first and second surfaces of the wrapping tape 2. The wrapping tape 2 is adapted to be wrapped around the outer circumferential surface of the sleeve and is detachably connected to the first connector 3 or the fourth connector 6 via the third connector 5, so that the sleeve can fix the patient's forearm to the support rod 7.

[0068] In this embodiment, the fourth connector 6 is placed on the first side of the wrapping tape 2. The third connector 5 is placed on the first and second sides of the wrapping tape 2.

[0070] Furthermore, the fourth connector 6 extends along the length of the winding tape 2 so that the third connector 5 and the fourth connector 6 can be detachably connected.

[0071] In this embodiment, the working principle of the PFNA surgical arm fixation device is as follows:

[0072] The medical staff instructed the patient, lying on operating table 8, to place their forearm on the second bar; at this point, the patient's hand was close to the first bar, and the third bar was suitable for restraining the patient's forearm (e.g., Figure 1 (As shown).

[0073] Medical staff use the detachable connection between the first connector 3 and the second connector 4 to form a sleeve with open ends around the fixing strap 1, thereby placing the patient's forearm, the second rod, and the third rod inside the sleeve (e.g., Figure 6 and Figure 7 (As shown in the image). At this time, the patient's upper arm is located at one end of the opening of the sheath and is placed outside the sheath.

[0074] Two wrapping tapes 2 are cross-wrapped around the outer circumference of the sleeve, and detachably connected to the first connector 3 or the fourth connector 6 via the third connector 5, so that the sleeve can fix the patient's forearm to the support rod 7 (e.g., Figure 8 (As shown). At this time, the wrapping tape 2 closes the openings at both ends of the sleeve so that the upper end of the first rod, the second rod, the third rod and the patient's forearm are all placed in the inner cavity of the sleeve, that is, the patient's forearm is effectively fixed on the support rod 7.

[0075] In summary, the PFNA surgical arm fixation device provided in this application allows a single medical professional to fix the patient's forearm through the cooperation of the fixation strap, wrapping strap, and connectors.
