Description

Technical Field

[0001] The utility model relates to the technical field of hemostatic devices, in particular to a dual-purpose hemostatic device for nail placement in posterior orthopedic internal fixation surgery. Background Art

[0002] When orthopedics performs posterior internal fixation and bone grafting fusion surgery on the cervical, thoracic, and lumbar spine, it is necessary to insert pedicle screws. When inserting the screws, the opening cone, circuit opener, and scout are first inserted, and then the positioning needle is inserted for positioning. Before inserting the positioning needle, the circuit opener pushes open the pedicle screw channel and bleeding occurs. At this time, bone wax is needed to fill the bleeding area.

[0003] In existing orthopedic posterior fixation surgeries, the surgeon will ask the operating room nurse to cut a piece of sterile gauze with a developing barium line, approximately 3cm x 3cm, on the operating table. The four corners are folded inward twice to form a small gauze ball with a diameter of approximately 1cm. The ball is then clamped with the tip of a forceps. Bone wax is then rolled into a cone with a base of approximately 1cm and a height of 1cm, with the bottom fitted onto the gauze ball. When in use, the forceps are held and pressed downward on the bleeding nail track to achieve the effect of stopping the bleeding.

[0004] However, this device requires the operating room nurse to temporarily cut the gauze on the sterile operating table. Orthopedic surgery involves a large number of instruments, and the surgeons are skilled and the operation is very fast. Temporary cutting of the gauze on the table will delay the operating room nurse's coordination speed and fluency. In addition, the gauze cut on the sterile operating table is too small, which also poses a risk of loss. The gauze cut and stacked by each operating room nurse varies in size and shape, which also causes inconvenience to the doctor when using it. Sometimes the gauze needs to be cut again to make small gauze balls, which delays the operation process. Therefore, the utility model proposes a dual-purpose orthopedic posterior internal fixation surgery nail placement hemostasis device. Utility Model Content

[0005] The purpose of the utility model is to address the problem in the background technology that during orthopedic posterior internal fixation surgery, bleeding is inevitable when the nail is placed. When stopping the bleeding, a temporary gauze ball can only be made on the table and clamped with cocoa forceps, and bone wax is placed on it to stop the bleeding, which greatly increases the difficulty and speed of operation for operating room nurses and fails to meet the current requirements of fast and smooth surgical cooperation. In addition, the small gauze balls made by operating room nurses are of different sizes and there is also a risk of loss.

[0029] like Figure 1 and Figure 2As shown, the utility model proposes a dual-purpose orthopedic posterior internal fixation surgical nail placement and hemostasis device, comprising: a first clamp handle 1 and a second clamp handle 2, the first clamp handle 1 and the second clamp handle 2 are cross-arranged and rotatably connected by a rotating shaft to form a cross clamp shape; the rear ends of the first clamp handle 1 and the second clamp handle 2 constitute a hand clamping section, and the front ends of the first clamp handle 1 and the second clamp handle 2 constitute a clamping section, which is convenient for stably clamping a small gauze ball; a grip 3 fixedly arranged at one end of the first clamp handle 1 and the second clamp handle 2, and the grip 3 is an elliptical structure to improve the comfort of finger pressing, and a frosted surface is provided on the outer side of the other end of the first clamp handle 1 and the second clamp handle 2, which is convenient for directly inserting bone wax at the end, increasing the friction of the connection and avoiding falling; a positioning component 4 for limiting is arranged between the first clamp handle 1 and the second clamp handle 2, which can enable the first clamp handle 1 and the second clamp handle 2 to stably clamp the small gauze ball to avoid falling or losing.

[0030] like Figures 2 to 4 As shown, the positioning assembly 4 includes a fixed frame 400 fixedly arranged on the first clamp handle 1, the interior of the fixed frame 400 is hollow, a guide rod 401 is fixedly arranged inside the fixed frame 400, and the outer wall of the guide rod 401 is movably sleeved with a connecting block 402, which can guide the connecting block 402 to make the movement of the connecting block 402 more stable, one end of the connecting block 402 is fixedly provided with a limit plate 403, and the limit plate 403 is inclined, the other end of the connecting block 402 is fixedly provided with a first connecting seat 404, and one end of the first connecting seat 404 is rotatably connected There is a connecting rod 405, one end of which is rotatably connected to a second connecting seat 406. The second connecting seat 406 is fixedly connected to the second clamping handle 2, and can link the first clamping handle 1 and the second clamping handle 2, thereby achieving stable limiting. The outer wall of the guide rod 401 is sleeved with a spring 407, one end of the spring 407 is fixedly connected to the fixed frame 400, and the other end of the spring 407 is fixedly connected to the connecting block 402, which can limit the connecting block 402 and provide thrust to facilitate the opening of the first clamping handle 1 and the second clamping handle 2, thereby facilitating the removal of the clamped small yarn ball.

[0031] like Figure 3 and Figure 4 As shown, the positioning assembly 4 also includes a limit rod 408 rotatably arranged inside the first clamp handle 1, and a limit block 409 is fixedly arranged on the outer wall of the limit rod 408, and the limit block 409 is engaged with the limit plate 403, which can stably limit the connecting block 402, and a push block 410 is fixedly arranged on the outer wall of the limit rod 408, which is convenient for pushing the limit rod 408 to drive the limit block 409 to rotate.

[0032] Furthermore, the opposing surfaces of the clamping sections of the first clamping handle 1 and the second clamping handle 2 are respectively provided with anti-slip grooves 5, which can increase the friction force of clamping the small yarn ball and prevent it from falling.

[0033] like Figure 2 As shown, a through slot 6 is provided on the first clamp handle 1, and positioning holes 7 are respectively provided on both sides of the inner wall of the through slot 6. A positioning column 8 is movably sleeved inside the positioning hole 7. The positioning column 8 is fixedly connected to both ends of the limiting rod 408, which can limit the limiting rod 408 and make the limiting rod 408 rotate stably.

[0034] In addition, the ends of the clamping sections of the first clamp handle 1 and the second clamp handle 2 are rounded to avoid injuring the patient during the pressing of the bone wax.

[0035] Furthermore, the first clamp handle 1 and the second clamp handle 2 are elliptical in shape in the closed clamping section, thereby increasing the bone wax fitting surface and improving the stability of bone wax insertion.

[0036] The working principle of this embodiment is as follows: On the operating table, the operating room nurse cuts a sterile gauze with a developing barium line, approximately 3 cm x 3 cm, and folds the four corners inward twice to form a small gauze ball with a diameter of approximately 1 cm. By pressing the grip 3 with their fingers, the first clamp handle 1 and the second clamp handle 2 intersect to clamp the small gauze ball. The second clamp handle 2 pushes the linkage rod 405 via the second connecting seat 406. The linkage rod 405 drives the connecting block 402 to slide along the outer wall of the guide rod 401 via the first connecting seat 404. The connecting block 402 drives the limiting plate 403 to move, and the limiting plate 403 slides on the limiting block 409 on the limiting rod 408. The limiting plate 403 and the limiting block 409 interlock, preventing the first and second clamp handles 1 and 2 from opening, thereby stably clamping the small gauze ball. Then roll the bone wax into a cone with a base of about 1 cm and a height of 1 cm, with the bottom fitted on the gauze ball. When using, hold the first clamp handle 1 and the second clamp handle 2, and press the bone wax downward on the bleeding nail track to achieve the effect of stopping bleeding.

[0037] Furthermore, the push block 410 is manually pushed to rotate 90 degrees with the limit rod 408 as the rotation axis. The limit rod 408 rotates in the positioning hole 7 through the positioning column 8, so that the limit rod 408 drives the limit block 409 to rotate 90 degrees, and cooperates with the spring 407 to push the connecting block 402 to slide on the guide rod 401. The guide rod 401 drives the connecting rod 405 to move through the first connecting seat 404, and the connecting rod 405 drives the second connecting seat 406 to drive the second clamp handle 2 to move, so that the clamped small gauze ball is loosened to prevent the gauze ball from falling or being lost, thereby improving the speed and fluency of hemostasis cooperation and making it more convenient to use.

[0038] Secondly, after the first clamp handle 1 and the second clamp handle 2 are closed, they are limited by the positioning component 4, and the conical bone wax is plugged into the closed ends of the first clamp handle 1 and the second clamp handle 2. The frosted surface increases the friction of the bone wax connection to prevent it from falling during use. The connected bone wax is pressed on the bleeding nail path to achieve a hemostatic effect, eliminating the need for operating room nurses to make small gauze balls on the table, which is more time-saving, labor-saving and convenient, and there is no risk of losing small gauze balls.

[0039] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
