Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to a thread hanger applicable to an operating table. Background Art

[0002] Surgery is a method of treating certain diseases with knives and other instruments. During surgery, the skin needs to be incised, and after surgery, the wound needs to be sutured. The suturing threads used have various specifications and need to be sutured in different sequences. Therefore, a thread hanger needs to be set up beside the operating table, and the suturing threads to be used are installed on the thread hanger in advance for convenient direct use.

[0003] In the prior art, a thread hanger is proposed in the Chinese patent document Cardiovascular Surgery Thread Hanger with the publication number CN219183911U. The thread hanger includes a support clip. An L-shaped support rod is fixedly installed on the top side of the support clip. A fixed clamping structure is movably installed on the support clip. A bottom plate is fixedly installed on the L-shaped support rod. A plurality of adjustment sliders are slidably installed on the L-shaped support rod, and the adjustment sliders are slidably installed on the top side of the bottom plate. Through the settings of structures such as a fixed sleeve, a thread hanging loop, and a limiting rod, the suturing threads required during surgery are respectively wound around the corresponding thread hanging loops for easy distinction and to prevent entanglement. The other end passes through the adjustment sliders on the corresponding limiting rods. By pulling the extrusion clip block, the end of the suturing thread can be fixed or loosened, facilitating the adjustment of the suturing thread length. When fixing the suturing thread, the thread hanging loop can be rotated to make it in a tight state for convenient shearing. However, the bracket for placing the suturing threads is horizontally arranged. In order to place a variety of suturing threads, the length of the bracket will be designed to be relatively long. And in order to facilitate the taking of the suturing threads, the height of the bracket needs to be set at a height that can be reached by raising the hand. Then, the position of the bracket placed beside the operating bed will occupy relatively more space and affect the actions of medical staff. Therefore, the present application provides a thread hanger applicable to an operating table to meet the requirement of reducing the impact on the actions of medical staff while ensuring the convenient taking of suturing threads.

[0016] Advantages of the present invention:

[0017] 1. For the thread hanger applicable to the operating table, by setting the lifting component, when it is necessary to take the suture, push the push plate, and the sliding rod can be driven to descend and slide under the transmission of the semi-gear, the rack and the first gear, so that the thread hanger descends to a suitable height, which is convenient for medical staff to take the suture. After taking it, release the push plate, and the torsion spring will rebound to drive the central rod to rotate in the reverse direction, and then drive the sliding rod to rise, so that the thread hanger rises, avoiding interference and influence on the actions of medical staff.

[0018] 2. For the thread hanger applicable to the operating table, by setting the rotating component, in the process of pushing the thread sleeve to rotate, the spring is used to squeeze the limiting block into the groove, realizing the self-stopping function of the rotation of the thread sleeve, and avoiding the situation that the rotation angle of the thread sleeve is too large due to the excessive force of the medical staff rotating the thread sleeve, which is not convenient for selecting the suture.

[0019] 3. For the thread hanger applicable to the operating table, by setting the adjusting component and the positioning component, unlocking the extension rod and opening and closing the clamping plate can be realized by rotating the collar, and then the extension rod can be extended, which is convenient for the connection between the positioning component and the operating bed. After aligning the clamping plate with the guardrail on the side of the operating bed and releasing the collar, the clamping plate is merged and bound to the outer surface of the guardrail under the driving force of the resilience of the second spring, and at the same time, the extension rod can be locked. Driving two groups of structures by the collar to complete the corresponding functions demonstrates the linkage of the device. Description of the drawings

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0032] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meanings understood by those with ordinary skills in the field to which the present invention belongs.

The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0033] Such as Figures 1 to 8As shown in the figure, a set of wire hangers applicable to an operating table includes a base 1. A vertical rod 2 is fixedly connected to the upper surface of the base 1. A sliding rod 3 is movably inserted into the vertical rod 2. A lifting component 4 is arranged inside the base 1. A rotating component 5 is arranged at the top of the sliding rod 3. A hoop 7 is fixedly sleeved on the outer surface of the vertical rod 2. An adjusting component 8 is arranged on the outer surface of the hoop 7. A positioning component 9 is arranged at the end of the adjusting component 8. The lifting component 4 acts inside the sliding rod 3 to drive the rotating component 5 to lift. The adjusting component 8 and the positioning component 9 are cooperatively arranged to realize the linkage of adjustment and positioning;

[0034] Place the device beside the operating bed. Use the adjusting component 8 to adjust the distance between the vertical rod 2 and the operating bed to make the fixation more convenient. Then use the positioning component 9 to fixedly connect with the side crossbar of the operating bed. During the operation, use the lifting component 4 to lift and lower the rotating component 5. When not in use, the rotating component 5 is placed at a higher position and will not affect the movement of medical staff. When in use, lower it. Different suture threads can be selected through the rotating component 5.

[0035] As Figure 2 、 Figure 3 and Figure 4 shown, the lifting component 4 includes an inner rod 401 movably inserted into the middle of the upper surface of the base 1. A gear one 402 is fixedly sleeved on the outer surface of the inner rod 401 extending into the base 1. A central rod 403 is rotatably connected inside the base 1. A push plate 404 is fixedly connected to the outer surface of the central rod 403. A semi-gear 405 is fixedly sleeved at the intersection of the push plate 404 and the central rod 403. A rack 407 is slidably arranged on the inner wall of the base 1. Both sides of the rack 407 are meshed and connected with the gear one 402 and the semi-gear 405 respectively. The inner rod 401 is slidably connected inside the sliding rod 3. A slider 408 is fixedly connected to the outer surface of the inner rod 401. A spiral groove 409 is opened on the inner wall of the inner rod 401. The slider 408 slides inside the spiral groove 409. A torsion spring 406 is sleeved on the outer surface of the central rod 403. One end of the torsion spring 406 is fixedly connected to the outer surface of the central rod 403, and the other end is fixedly connected to the inner wall of the base 1;

[0036] Medical staff use their legs to push the push plate 404. The push plate 404 rotates around the central rod 403 and drives the central rod 403 and the half gear 405 to rotate synchronously. The rotation of the central rod 403 will compress the torsion spring 406, and the rotation of the half gear 405 will drive the rack 407 to move linearly within the base 1. Further, the rack 407 will drive the first gear 402 on the other side to rotate. While the first gear 402 rotates, it will drive the inner rod 401 to rotate inside the slide rod 3. Since the slider 408 on the outer surface of the inner rod 401 is slidably engaged inside the spiral groove 409, the rotation of the inner rod 401 will drive the slide rod 3 to slide along the vertical axis of the vertical rod 2, and further drive the thread hanging rack 6 to descend to an appropriate height, facilitating the medical staff to pick up the suture thread. When the picking is completed and the push plate 404 is released, the rebound of the torsion spring 406 will drive the central rod 403 to rotate in the reverse direction, and further drive the slide rod 3 to rise, causing the thread hanging rack 6 to rise, avoiding interference and influence on the actions of the medical staff.

[0037] As Figure 4 and Figure 5 shown, the rotating assembly 5 includes a top plate 501 fixedly connected to the top end of the inner rod 401. A thread hanging sleeve 502 is movably sleeved on the outer surface of the top plate 501. A cavity 503 is formed on the outer surface of the top plate 501. A limiting block 504 is slidably connected inside the cavity 503. A groove 505 is formed on the inner wall of the thread hanging sleeve 502. The limiting block 504 is movably engaged inside the groove 505. A first spring 506 is arranged inside the cavity 503. The first spring 506 abuts against the end of the limiting block 504. The thread hanging racks 6 are distributed in a circular matrix on the outer surface of the thread hanging sleeve 502;

[0038] When the medical staff selects the suture thread, pushing the thread hanging rack 6 will drive the thread hanging sleeve 502 to rotate around the top plate 501. During the rotation, the limiting block 504 will be squeezed into the cavity 503 and compress the first spring 506. When the next thread hanging rack 6 rotates in front, the spring pushes the limiting block 504 to snap into the current groove 505, stopping the rotation of the thread hanging sleeve 502, realizing the self-stopping function of the rotation of the thread hanging sleeve 502, and avoiding the situation that the rotation angle of the thread hanging sleeve 502 is too large due to the excessive force of the medical staff rotating the thread hanging sleeve 502, which is not convenient for selecting the suture thread.

[0039] As Figures 6 to 7As shown in the figure, the adjusting component 8 includes a sleeve 801 fixedly connected to the outer surface of the hoop 7. An extension rod 802 is limited and slidably connected inside the sleeve 801. A collar 803 is movably sleeved at one end of the extension rod 802 away from the sleeve 801. A toothed ring 805 is fixedly connected to one side of the collar 803 close to the sleeve 801. A straight rod 804 is arranged on the outer surface of the extension rod 802. A second gear 806 is fixedly connected to one end of the straight rod 804 close to the collar 803. The second gear 806 is meshed with the toothed ring 805. An eccentric wheel 807 is fixedly connected to one end of the straight rod 804 extending into the sleeve 801. A clamping groove 808 is formed on the inner wall of the sleeve 801. The eccentric wheel 807 is clamped inside the clamping groove 808.

[0040] During the process of rotating the collar 803, the toothed ring 805 will be driven to rotate. Further, the toothed ring 805 will drive the second gear 806 to rotate. Through the transmission of the straight rod 804, the eccentric wheel 807 can be synchronously driven to rotate and slide out of the clamping groove 808. At this time, pulling the collar 803 along the axis of the sleeve 801 can drive the extension rod 802 to gradually slide out of the sleeve 801. Stop when it moves to a suitable position. The device can be placed at a suitable position according to needs and then the adjusting component 8 is used to extend the extension rod 802, which is convenient for the positioning component 9 to be connected to the operating table.

[0041] As Figures 6 to 8 As shown in the figure, the positioning component 9 includes a support 901 fixedly connected to the end of the extension rod 802. A shaft rod 902 is movably inserted through the outer surface of the support 901. A clamping plate 903 is fixedly sleeved on the outer surface of the shaft rod 902. There are two clamping plates 903. The two clamping plates 903 are spliced to form a circular ring structure. A toothed ring 904 is fixedly connected to one side of the collar 803 away from the sleeve 801. A bevel gear 905 is fixedly connected to the end of the shaft rod 902. The toothed ring 904 is meshed with the bevel gear 905. A second spring 906 is arranged between the two clamping plates 903.

[0042] While rotating the collar 803, the toothed ring 904 on the other side of the collar 803 will rotate accordingly, and the toothed ring 904 will synchronously drive the bevel gear 905 to rotate. The rotation of the bevel gear 905 will drive the clamping plate 903 to rotate around the shaft rod 902 through the shaft rod 902, so that the two clamping plates 903 are opened and the second spring 906 is stretched. After aligning the clamping plates 903 with the guardrail on the side of the operating table, release the collar 803. The second spring 906 rebounds to drive the two clamping plates 903 to merge and bind on the outer surface of the guardrail, completing the fixation of the device.

[0043] For the technical solution provided by the present invention, the whole device is carried to the side of the operating table. Then, the collar 803 is rotated. During the rotation of the collar 803, the toothed ring 805 will be driven to rotate. Further, the toothed ring 805 will drive the second gear 806 to rotate. Through the transmission of the straight rod 804, the eccentric wheel 807 can be synchronously driven to rotate and slide out of the card slot 808. At this time, pulling the collar 803 along the axis of the sleeve 801 can drive the extension rod 802 to gradually slide out of the sleeve 801. When it moves to a suitable position, stop. The device can be placed at a suitable position according to needs, and then the extension rod 802 can be extended by using the adjustment assembly 8 to facilitate the connection between the positioning assembly 9 and the operating bed. While the collar 803 is rotating, the toothed ring 904 on the other side of the collar 803 will rotate accordingly, and the toothed ring 904 will synchronously drive the bevel gear 905 to rotate. The rotation of the bevel gear 905 will drive the clamping plate 903 to rotate around the shaft rod 902 through the shaft rod 902, so that the two clamping plates 903 are opened and the second spring 906 is stretched. After aligning the clamping plates 903 with the guardrail on the side of the operating bed, the collar 803 is released. The second spring 906 rebounds to drive the two clamping plates 903 to merge and bind to the outer surface of the guardrail, completing the fixation of the device. Driving the collar 803 to rotate in the reverse direction by sleeving the bevel gear 905 will cause the eccentric wheel 807 to rotate and be clamped in the corresponding card slot 808, realizing the locking of the extension rod 802 and ensuring the stability of the extension rod 802 and the sleeve 801. Driving two groups of structures by the collar 803 to complete corresponding functions demonstrates the linkage of the device;

[0044] During the operation, when a suture is needed, the medical staff use their legs to push the push plate 404. The push plate 404 rotates around the central rod 403 and drives the central rod 403 and the half gear 405 to rotate synchronously. The rotation of the central rod 403 will squeeze the torsion spring 406, and the rotation of the half gear 405 will drive the rack 407 to move linearly within the base 1. Furthermore, the rack 407 will drive the first gear 402 on the other side to rotate. While the first gear 402 rotates, it will drive the inner rod 401 to rotate inside the slide rod 3. Since the slider 408 on the outer surface of the inner rod 401 is slidably clamped inside the spiral groove 409, the rotation of the inner rod 401 will drive the slide rod 3 to slide along the vertical axis of the vertical rod 2. Furthermore, it will drive the wire hanging sleeve 502 to descend to an appropriate height, facilitating the medical staff to pick up the suture. When the picking-up is completed and the push plate 404 is released, the rebound of the torsion spring 406 will drive the central rod 403 to rotate in the reverse direction. Furthermore, it will drive the slide rod 3 to rise, causing the wire hanging sleeve 502 to rise, avoiding interference and impact on the actions of the medical staff. When the medical staff select the suture, pushing the wire hanging rack 6 will drive the wire hanging sleeve 502 to rotate around the top plate 501. During the rotation, the limiting block 504 will be squeezed into the cavity 503 and compress the first spring 506. When the next wire hanging rack 6 rotates in front, the spring will push the limiting block 504 to snap into the current groove 505, causing the rotation of the wire hanging sleeve 502 to stop, realizing the self-stopping function of the rotation of the wire hanging sleeve 502 and avoiding the situation that the rotation angle of the wire hanging sleeve 502 is too large due to the excessive force of the medical staff rotating the wire hanging sleeve 502, which is not convenient for selecting the suture.
