Description

Technical Field

[0001] The utility model relates to the technical field of medical use, in particular to a wrist arthroscopic traction frame. Background Art

[0002] The main function of the wrist arthroscopic traction frame is to pull the wrist and provide sufficient operating space for surgery. Because the joint space of the wrist joint is very narrow, proper traction is required to have a sufficient operating field of view. Using the wrist arthroscopic traction frame, there is no longer a need for a surgical assistant to fix the patient's arm. The wrist arthroscopic traction frame can be flexibly adjusted to meet the angle required for surgery.

[0003] Existing wrist arthroscopy traction frames are mostly fixed to the operating table. After the patient lies on the operating table, the medical staff then secures the patient's fingers with sterile finger gloves and applies traction, and then the surgery begins. However, existing wrist arthroscopy traction frames cannot fine-tune the patient's wrist angle after securing and tractioning the patient's fingers, thus failing to meet the more sophisticated surgical requirements.

[0004] Therefore, this embodiment provides a wrist arthroscopic traction frame, which allows fine-tuning of the patient's wrist angle, thereby meeting more refined surgical requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a wrist arthroscopic traction frame, which can fine-tune the angle of the patient's wrist after fixing and traction the patient's fingers, thereby meeting more refined surgical requirements.

[0029] A wrist arthroscopy traction frame comprises a support body 1, an extension rod 2, a fixing mechanism 3 and a limiting mechanism 7.

[0030] like Figures 1 to 3 As shown, the extension rod 2 is horizontally arranged on the upper part of the bracket body 1, the bottom of the fixing mechanism 3 can be used to fix the sterile finger sleeve 4, the top of the fixing mechanism 3 can slide horizontally along the length direction of the extension rod 2, and the limiting mechanism 7 is provided on the extension rod 2, and the limiting mechanism 7 can be used to limit the horizontal sliding of the fixing mechanism 3;

[0031] Specifically, during the operation, the wrist arthroscopy traction frame is fixed on the operating table. When the patient lies on the operating table, the medical staff fixes the patient's fingers with sterile finger sleeves 4 for traction. Then the medical staff drives the patient's wrist to the required angle by moving the fixing mechanism 3, and then fixes the position of the fixing mechanism 3 by the limiting mechanism 7 to limit the horizontal sliding of the fixing mechanism 3, so that the wrist arthroscopy traction frame can still fine-tune the patient's wrist angle after fixing and traction of the patient's fingers, without the need for medical staff to adjust the patient's wrist by hand. The operation is simple and the fixed angle can be maintained, thereby meeting more refined surgical requirements and improving the surgical effect.

[0032] As a further implementation of this embodiment, Figure 1 and Figure 2As shown, the fixing mechanism 3 includes a slider 300, a connecting rope 301 and a hanging plate 302. The slider 300 is connected to the hanging plate 302 by the connecting rope 301. A slide groove 5 is provided on the extension rod 2. The extension direction of the slide groove 5 is consistent with the length direction of the extension rod 2. The slider 300 can slide horizontally in the slide groove 5. Specifically, when the patient's finger is fixed and pulled by the sterile finger cuff 4, the horizontal left and right movement of the slider 300 can drive the hanging plate 302 and the connecting rope 301 to move synchronously, thereby driving the sterile finger cuff 4 to move. When it moves to the required angle, the fixing mechanism 3 is fixed by the limiting mechanism 7, thereby completing the fine-tuning of the patient's hand, meeting more refined surgical requirements, and improving the surgical effect.

[0033] As a further implementation of this embodiment, Figure 2 and Figure 3 As shown, a plurality of notches 6 are provided at equal intervals on the hanging plate 302, and the notches 6 can be used to fix the sterile finger cuff 4. Specifically, the top of the sterile finger cuff 4 has a rope, and the rope is fixed to the notch 6, thereby fixing the sterile finger cuff 4 to the hanging plate 302, so as to achieve fixed traction of the patient's finger.

[0034] As a further implementation of this embodiment, Figures 1 to 3 As shown, the limiting mechanism 7 includes a limiting bolt 700, and a screw hole matching the limiting bolt 700 is provided on the top of the slider 300. Specifically, during operation, when the movement of the slider 300 drives the patient's wrist to the desired angle, the limiting bolt 700 is screwed into the screw hole of the slider 300. At this time, the nut part of the limiting bolt 700 is tightly abutted against the top of the extension rod 2 to limit the horizontal sliding of the fixing mechanism 3, thereby fixing the patient's wrist angle. The structure is simple and easy to operate.

[0035] As a further implementation of this embodiment, the extension rod 2 is connected to the bracket body 1 through a universal ball joint. In this embodiment, the universal ball joint is not shown in the figure. By adjusting the angle of the extension rod 2 to adapt to the surgical needs of different patients, the use range of the wrist arthroscopy traction frame is improved, the use cost is reduced, and thus the increase in the patient's surgical cost is avoided.

[0036] As a further implementation of this embodiment, Figure 1 and Figure 3As shown, the wrist arthroscopy traction frame includes a strap 8, which is fixed to the bracket body 1. The strap 8 includes a first part 800 and a second part 801. The first part 800 and the second part 801 are connected by Velcro. When the first part 800 and the second part 801 are connected, the strap 8 can be used to fix the patient's arm. Specifically, the patient's arm is fixed to the traction frame through the strap 8 to ensure the stability of the arm during the operation, avoid movement or shaking during the operation, and thus improve the surgical effect.
