Description

Technical Field

[0001] This invention relates to the field of thyroid surgical instruments, specifically to a thyroid retractor and suction device. Background Technology

[0002] The thyroid retractor and suction device is an indispensable auxiliary instrument in thyroid surgery. Its core function is to achieve traction and exposure of surgical incision tissue and timely removal of intraoperative bleeding and fluid accumulation, providing the surgeon with a clear and stable operating field while reducing intraoperative tissue damage and surgical risks. In clinical application, this type of instrument needs to balance operational flexibility and functional integration. It must meet the traction needs of different surgical incision locations (such as the neck and axilla) while also using negative pressure suction to manage intraoperative bleeding in real time, preventing blood from obscuring the surgical field and ensuring precise surgical execution. With the increasing prevalence of minimally invasive thyroid surgery (such as transaxillary thyroidectomy), higher demands are placed on the structural design and functional adaptability of the thyroid retractor and suction device, especially its ability to adapt to the limited surgical space of the axilla and its capacity for precise handling of multi-layered tissues.

[0003] In existing technologies, the structural design of integrated thyroid retractor and suction devices primarily revolves around basic traction and suction functions. Common technical solutions include integrating the retractor assembly and negative pressure suction tube using a fixing bracket. The retractor assembly is often a single plate-like or hook-like structure, and the traction position can be adjusted manually by adjusting the bracket height or angle. The negative pressure suction function is achieved by fixing the suction tube to the side of the retractor, with one end extending to the vicinity of the surgical incision and the other end connected to an external negative pressure device to absorb blood ooze. To improve operational convenience, some instruments adopt a detachable design for easy postoperative disinfection and cleaning. However, the overall structure still focuses on single traction and basic suction, without being specifically optimized for the delicate processing of multi-layered tissues or the operational needs of specific surgical approaches (such as the axillary approach). This results in the following shortcomings during surgical procedures:

[0004] 1. Existing instruments lack the ability to hold and position the inner layers of tissue in the axillary incision. In axillary approach surgery, the tissue layers at the incision site are complex (including skin, subcutaneous fat, fascia, muscle, etc.). The surgeon needs to separate the tissue layer by layer and perform precise operations. However, the existing retractor components can only achieve overall tissue traction and exposure at the initial incision, and cannot individually hold and fix the inner layers of tissue at different levels, which leads to easy tissue displacement during the operation and increases the difficulty of the separation operation.

[0005] 2. The adjustment structure of the hook plate is located on top. After the hook plate hooks the incision tissue, the assistant doctor needs to adjust the hook plate by raising and lowering the toothed plate. This requires both the assistant doctor and the surgeon to stand on one side of the surgical incision, which can easily lead to limited surgical space, slow down the surgical rhythm, and make it difficult for the doctor to perform surgery on the patient, increasing the operation time and the patient's intraoperative risks. Summary of the Invention

The three marking rings 623 can extend to the outside of the fixing sleeve 61. Specifically, when the pressure plate 56 abuts against the two limiting blocks 551, the marking ring 623 near the pull ring 63 is located outside the fixing sleeve 61, and the edge of the marking ring 623 is flush with the end of the fixing sleeve 61. When the pressure plate 54 abuts against the two limiting blocks 531, the marking ring 623 in the middle is located outside the fixing sleeve 61. 3 is located outside the first fixed sleeve 61, and the edge of the marking ring 623 is flush with the end of the first fixed sleeve 61. When the first pressure plate 52 and the two limiting blocks 511 come into contact, the marking ring 623 located away from the pull ring 63 is located outside the first fixed sleeve 61, and the edge of the marking ring 623 is flush with the end of the first fixed sleeve 61. Through the design of the three marking rings 623, it is convenient for the surgical assistant doctor to understand the status of the third pressure plate 56, the second pressure plate 54 and the first pressure plate 52 by the position of the three marking rings 623.

[0068] Working principle and usage process of this invention:

[0069] When installing and positioning the support assembly 1, insert one end of the support rod 12 vertically into the insertion hole, rotate the positioning screw 115 so that its end abuts against the support rod 12, and position the support rod 12 and the fixing block 111 so that the fixing block 111 is located on the side away from the patient's surgical incision, and position the fixing clamp 112 and the movable clamp 113 above and below the operating table respectively. Rotate the threaded rod 114 so that the movable clamp 113 slides on the fixing block 111, and clamp the operating table through the fixing clamp 112 and the movable clamp 113, and position the fixing block 111.

[0070] When installing the hook assembly 3, first align the mounting plate 31 with the connecting plate 24, ensuring the protrusion 311 is aligned with the groove at the bottom of the connecting plate 24. Manually apply force to the two actuating blocks 252, causing them to move closer together along the spring telescopic rods 251. The spring telescopic rods 251 deform under this force. Then, insert the protrusion 311 into the groove. When the mounting plate 31 and connecting plate 24 are in contact, the two locking blocks 32 are inserted into the two clearance slots 241. Release the force on the two actuating blocks 252, allowing the spring telescopic rods 251 to return to their natural state, pushing the two actuating blocks 252 away from each other. The two locking blocks 253 are then inserted into the two locking holes 321, engaging with the two locking blocks 32. This secures the mounting plate 31 and connecting plate 24. For aligning the threaded post 622 with the screw seat 671, pull the threaded post 6... 22. Drive the steel wire rope 62 to extend outward from the receiving cavity. Manually rotate the threaded column 622 to make it mesh with the screw seat 671. Align the threaded column 622 with the screw seat 671. Then rotate the limiting rod 682 on the fixing plate 65 so that its free end is outside the fixing plate 65. The coil spring deforms. Hold the fixing plate 64 so that the male connector 73 is aligned with the female connector 77. Make the fixing plate 64 and the fixing plate 65 fit together. At this time, the male connector 73 is inserted into the female connector 77. The male connector 73 and the female connector 77 are connected. The signal wire 72 and the signal wire 76 are connected. Remove the force on the limiting rod 682. The coil spring returns to its natural state. The free end of the limiting rod 682 forms abutment with the fixing plate 64, which can position the fixing plate 64 and the fixing plate 65. Then connect the negative pressure pipe 81 to the external negative pressure suction device.

[0071] When the surgeon makes an incision in the outer layer of the patient's axillary tissue, the surgical assistant stands on the side of the support rod 12 near the mounting frame 41. While using the pull plate 33 to pull the tissue at the incision site, the surgical assistant rotates the worm gear, which drives the winding roller 45 to rotate on the support 44, unfolding the steel wire rope 46. One end of the pull plate 33 is inserted horizontally into the incision. The connecting shell 22 is then rotated outside the connecting ball 26 to adjust the angle of the pull plate 33. After adjustment, the positioning screw 221 is rotated to make it contact the connecting ball 26, thus aligning the connecting shell 22 with the connecting ball 26. The positioning screw 14 is fixed between the two and rotated to make it abut against the support rod 12, positioning the moving block 13. At this time, the surgical assistant rotates the worm gear in the opposite direction, which drives the winding roller 45 to rotate on the bracket 44 through the worm wheel, winding and storing the steel wire rope 46, thereby pulling the adjusting vertical plate 21 to slide upward along the perforation, driving the hook plate 33 to move upward, and pulling the tissue at the patient's incision site upward. At this time, the camera 75 captures the image of the inside of the incision site in real time and feeds it back to the display host 71 in real time through the signal wire 1 72 and the signal wire 2 76 for display, so that the surgical assistant can observe it.When the surgeon makes an incision in the inner layer of tissue, and needs to locate the inner incision tissue, the surgical assistant pulls the pull ring 63 to move the steel wire rope 62 outward. This, in turn, pulls the steel wire rope 67 through the connecting post 621, threaded post 622, and screw seat 671. This, in turn, causes the pressure plate 56 to rotate around the hinge axis 3 via the fixing ring 561. When the pressure plate 56 contacts the two limiting blocks 551, it further causes the pressure plate 54 to rotate around the hinge axis 2. When the pressure plate 54 contacts the two limiting blocks 531, it further causes the pressure plate 1 to rotate. Rotating around hinge axis 52 causes pressure plate 52 to abut against the two limiting blocks 511, opening pressure plate 56, pressure plate 54, and pressure plate 52. All three marking rings 623 are located outside the fixing sleeve 61. When layered clamping and positioning of the inner tissue at the incision site is required, the surgeon uses pressure plate 52 and pull plate 33 to clamp and position the inner tissue. The surgeon places the incision tissue between pressure plate 52 and pull plate 33, and the surgical assistant reduces the pulling force on the pull ring 63, allowing the first coil spring 57 to return to its natural state. The incision tissue can be clamped by the pressure plate 52 and the pull hook plate 33. The pull ring 63 is moved closer to the fixing sleeve 61 by the steel wire ropes 67 and 62. The marking ring 623, located in the middle, is positioned outside the fixing sleeve 61, with its edge flush with the end of the fixing sleeve 61. When positioning the next layer of incision tissue, the surgeon places the incision tissue between the pressure plate 54 and the pressure plate 52. The surgical assistant further reduces the tension on the pull ring 63, causing the marking ring 623, located near the pull ring 63, to move closer to the pull ring 63. Located outside the first fixed sleeve 61, with the edge of the marking ring 623 flush with the end of the first fixed sleeve 61, the incision tissue can be clamped by the second clamping plate 54 and the first clamping plate 52. Similarly, the next layer of incision tissue can be clamped and positioned by the third clamping plate 56 and the second clamping plate 54, achieving the effect of layered clamping and positioning of the inner layer of incision tissue at the patient's surgical site. During this process, the surgical assistant doctor is located on the other side of the patient to assist the surgeon in the operation, which is beneficial for the doctor to perform the operation on the patient and reduces the operation time and the patient's intraoperative risks.

[0072] During the surgery, the surgical assistant manually rotates the placement plate 333 so that its free end rotates to the outside of the hook plate 33. Then, the connecting pipe 335 is connected to the external negative pressure device. The two positioning screws 95 are rotated so that they do not contact the side wall of the hook plate 33, causing the auxiliary pressure plate 93 to rotate on the connecting frame 92 and contact the limiting plate 94. This causes the two sliders 91 to slide downwards along the two sliding grooves 332, bringing the auxiliary pressure plate 93 into contact with the top of the patient's skin. The two positioning screws 95 are then rotated in the opposite direction so that they both contact the side wall of the hook plate 33, fixing the position of the two sliders 91. This positions the auxiliary pressure plate 93, improving the tissue positioning effect at the patient's incision site. When surgical instruments need to be adjusted... When cleaning tissue attached to the end of the surgical instrument, the surgeon inserts the end of the surgical instrument into the insertion hole 334, thereby extending into the connecting tube 335. The external negative pressure device is activated, causing air to be drawn out of the connecting tube 335 and external air to enter the connecting tube 335. When the air flows, it comes into contact with the surgical instrument, thereby suctioning away the tissue attached to the surgical instrument and achieving the effect of cleaning the tissue attached to the surgical instrument. During this process, when it is necessary to treat bleeding at the patient's incision site, the surgeon inserts the end of the surgical instrument into the inner layer of the operating ring 84. The surgical instrument applies force to the operating ring 84, bringing the negative pressure suction nozzle 83 close to the bleeding site. The corrugated tube 82 deforms, and the medical staff activates the external negative pressure suction device, which absorbs the bleeding at the incision site through the negative pressure tube 81.

[0073] After the thyroid surgery is completed, the surgical assistant pulls the pull ring 63, causing the steel wire rope 62 to move outward. This sequentially pulls the pressure plate 56, pressure plate 54, and pressure plate 52 to unfold, thus releasing the clamping of the inner layer of the patient's incision tissue. Rotating the two positioning screws 95 releases their contact with the sidewall of the hook plate 33, allowing the two sliders 91 to slide back onto the hook plate 33 and reposition the auxiliary pressure plate 93 into the receiving groove 331. Rotating the two positioning screws 95 again releases their contact with the sidewall of the hook plate 33, and then rotating the worm gear unfolds the steel wire rope 46, releasing the suspension of the hook plate 33. The surgeon can then remove the hook plate 33 and perform suturing of the incision. The surgeon assists by applying force to the limiting rod 682, preventing its free end from contacting the first fixing plate 64, thus disassembling the first fixing plate 64 and the second fixing plate 65, thereby separating the male connector 73 from the female connector 77. Then, the threaded column 622 is rotated to separate it from the screw seat 671, disassembling the negative pressure tube 81 from the external negative pressure suction device. The surgeon manually applies force to the two actuating blocks 252, causing them to move closer to each other along the spring telescopic rod 251, so that the two locking blocks 253 are located outside the two locking holes 321, thus disassembling and separating the mounting plate 31 from the connecting plate 24, thereby disassembling the hook plate 33 as a whole, which facilitates the postoperative disinfection of the hook plate 33 by medical staff.
