Description

Technical Field

[0001] This utility model relates to the technical field of thyroid surgical instruments, and in particular to a traction frame for endoscopic thyroid surgery. Background Technology

[0002] Endoscopic thyroid surgery is a minimally invasive surgical technique used to treat thyroid diseases. It involves making small incisions in the neck or other parts of the body (such as the areola, armpit, or oral vestibule) to insert a scope and other specialized instruments, allowing the surgeon to observe and manipulate the thyroid tissue. An endoscopic thyroid surgery traction frame is an auxiliary tool used in this procedure to address challenges such as limited operating space and difficulty in exposing the thyroid gland, thereby improving surgical efficiency and success rates. By fixing retractors or sutures used to separate the anterior neck muscles to the traction frame, it effectively pulls apart and stabilizes the tissue in the surgical area, allowing for more complete exposure of the thyroid gland. This helps the surgeon to observe the surgical site more clearly, improving the accuracy and safety of the procedure.

[0003] When using a traction frame in endoscopic thyroid surgery, it is indeed necessary to adjust the height and angle of the frame based on factors such as the patient's surgical site, individual anatomical differences, and specific surgical requirements. The height of the traction frame should be adjusted so that the surgeon can clearly see the surgical area, including the thyroid gland and surrounding anatomical structures. This helps the surgeon to make more accurate judgments and operations, reducing accidental injury caused by unclear vision. The patient's position may need to be adjusted during the surgery, such as raising or lowering the head. Therefore, the height of the traction frame also needs to be adjusted accordingly to ensure that surgical instruments and traction devices can smoothly enter the surgical area and maintain a stable operating environment. Utility Model Content

[0004] The purpose of this invention is to provide a traction frame for endoscopic thyroid surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A traction frame for endoscopic thyroid surgery, comprising:

[0007] The mounting base is provided with a support tube one, and a support tube two is provided inside the support tube one. A support frame is fixedly connected to the support tube two.

[0008] A fixing component is provided on the second support tube, which is used to adjust the position of the second support tube on the first support tube;

[0009] A connecting component, which is mounted on a support frame, is used to laterally adjust the fixed position of the pull hook.

[0010] Preferably, the fixing component includes an arc-shaped groove, which is evenly and equidistantly disposed on the inner wall of the support tube.

[0011] Preferably, the fixing component further includes an extrusion groove, which extends through and is equidistantly disposed at the end of the second support tube.

[0012] Preferably, the extrusion groove is provided with balls, which are adapted to the arc surface of the extrusion groove.

[0013] Preferably, the fixing component further includes a connecting rod, which is disposed inside the support tube.

[0014] Preferably, the connecting rod comprises three sections: a threaded section, a connecting section, and a pressing section.

[0015] Preferably, the threaded section of the connecting rod is located at the end away from the first support tube, and is threadedly connected to the inner wall of the second support tube. A torsion handle is provided at the end of the connecting rod near the threaded section.

[0016] Preferably, the connecting section of the connecting rod is used to connect the threaded section and the extrusion section.

[0017] Preferably, an extrusion bead is fixedly provided at one end of the extrusion section of the connecting rod, the extrusion bead is located above the ball bearing, and the size of the ball bearing is adapted to the size of the arc groove.

[0018] Preferably, the connecting component includes a slot, which is equidistantly arranged on the support frame, and a strap is provided in the slot for connecting the hook.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When the fixing component is released, the second support tube can be adjusted vertically and at an angle. When the fixing component acts on both the first and second support tubes, the position of this endoscopic thyroid surgery traction frame is relatively fixed. This means that the surgeon can flexibly adjust the height of the traction frame according to the patient's specific surgical needs. This height adjustment function helps optimize the surgical field of vision, allowing the surgeon to see the surgical area more clearly, thereby improving the accuracy and safety of the surgery.

[0021] The second support tube also allows for angle adjustment. This adjustment capability enables surgeons to adjust the angle of the traction frame according to different surgical steps and needs, in order to better expose and manipulate the thyroid gland. The flexibility of angle adjustment helps surgeons maintain a comfortable operating posture during surgery and reduces fatigue caused by prolonged surgery.

[0022] The connecting components allow surgeons to select the most suitable slot from multiple slots for tape installation, based on factors such as the surgical field of view and the patient's pathological location. This multi-position selection capability gives the traction frame greater flexibility and adaptability, enabling it to meet the needs of different surgical scenarios. Attached Figure Description

The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0032] Please see Figures 1-3 A traction frame for endoscopic thyroid surgery includes: a mounting base 1, on which fixing screws are provided to fix the upper components to the bed or surgical area; a support tube 101 is mounted on the mounting base 1, vertically mounted on the mounting base 1, providing the main support force for the traction frame; its internal space is used to accommodate and fix a second support tube 102, ensuring the stability of the entire traction frame structure; the second support tube 102 is disposed inside the first support tube 101, and the height and angle of the second support tube 102 can be adjusted according to the surgical needs to adapt to the anatomical structure and surgical requirements of different patients; a support frame 103 is fixedly connected to the second support tube 102 for fixing hooks; through the fixing action of the support frame 103, the hooks and other instruments can be stably applied to the surgical area, helping the doctor to better expose and manipulate the patient's thyroid gland;

[0033] A traction frame for endoscopic thyroid surgery further includes: a fixation component mounted on a second support tube 102, used to adjust the position of the second support tube 102 on a first support tube 101. When the fixation component is released, the second support tube 102 can be adjusted vertically and at an angle. When the fixation component acts on both the first and second support tubes 101 and 102, the position of the endoscopic thyroid surgery traction frame is relatively fixed. This means that the surgeon can flexibly adjust the height of the traction frame according to the patient's specific surgical needs. This height adjustment function helps optimize the surgical field of vision, allowing the surgeon to see the surgical area more clearly, thereby improving the accuracy and safety of the surgery. In addition to height adjustment, the second support tube 102 can also be angled. This adjustment capability allows the surgeon to adjust the angle of the traction frame according to different surgical steps and needs to better expose and manipulate the thyroid gland. The flexibility of angle adjustment helps the surgeon maintain a comfortable operating posture during surgery, reducing fatigue caused by prolonged surgery.

[0034] A traction frame for endoscopic thyroid surgery further includes a connecting component mounted on a support frame 103. This connecting component is used for lateral adjustment of the retractor's fixation position. The connecting component allows the surgeon to fine-tune the retractor's position as needed during surgery, ensuring the retractor accurately targets the thyroid gland and surrounding tissues. This optimizes the surgical field of view, allowing the surgeon to see the surgical area more clearly. By precisely adjusting the retractor's position, the surgeon can more accurately control the surgical procedure, avoiding unnecessary damage to surrounding normal tissues. This helps reduce surgical complications and improves surgical safety.

[0035] The fixing component includes arc-shaped grooves 2, which are evenly spaced on the inner wall of the first support tube 101. The fixing component also includes compression grooves 201, which penetrate and are evenly spaced at the ends of the second support tube 102. Ball bearings 202 are installed inside the compression grooves 201, and the size of the ball bearings 202 matches the arc surface of the compression grooves 201. By compressing and conforming the ball bearings 202 to the arc grooves 2, the position of the second support tube 102 is fixed. This design, where the ball bearings 202 are compressed and conform to the arc grooves 2, ensures precise fixation of the second support tube 102 on the first support tube 101. This fixing method not only ensures the stability of the traction frame during surgery but also avoids changes in the surgical field of view or operational errors caused by positional movement.

[0036] Furthermore, the fixing assembly also includes a connecting rod 203, which is disposed within the inner cavity of the second support tube 102. The connecting rod 203 comprises three sections: a threaded section, a connecting section, and a pressing section. The threaded section of the connecting rod 203 is located at the end furthest from the first support tube 101, and is threadedly connected to the inner wall of the second support tube 102. A torque handle 205 is provided at the end of the connecting rod 203 near the threaded section, and the raising and lowering of the connecting rod 203 can be controlled by turning the torque handle 205. The connecting section of the connecting rod 203 is used to connect the threaded section and the pressing section. A compression bead 204 is fixedly installed at one end of the compression section of the connecting rod 203. The compression bead 204 is located above the ball bearing 202. When the second support tube 102 slides to the correct position, the compression bead 204 at the bottom of the connecting rod 203 is gradually moved closer to the ball bearing 202 moving in the compression groove 201 by turning the torsion handle 205, until the ball bearing 202 fits into the arc groove 2, thus fixing the position of the second support tube 102 relative to the inner wall of the first support tube 101. After the operation, the medical staff can easily turn the torsion handle 205 in the opposite direction to raise the connecting rod 203 and release the compression effect on the ball bearing 202, thereby quickly resetting the second support tube 102 to its initial position. This easy reset characteristic makes the traction frame more flexible and reliable in multiple uses, and the height of the second support tube 102 can be adjusted according to the needs of the operation. This height adjustment flexibility allows the traction frame to adapt to the anatomical structure and surgical needs of different patients, improving the adaptability and success rate of the operation.

[0037] Furthermore, the connecting component includes slots 3, which are equidistantly arranged on the support frame 103. A strap 301 is installed within each slot 3 for connecting the pull hook. Because the slots 3 are equidistant, the surgeon can select the most suitable position from multiple slots 3 to install the strap 301, based on factors such as the surgical field of view and the patient's pathological location. This multi-position selection capability gives the traction frame greater flexibility and adaptability, meeting the needs of different surgical scenarios.
