Description

Technical Field

[0001] This utility model belongs to the field of endoscopic thyroid surgery retractor technology, and more specifically, it relates to an endoscopic thyroid surgery retractor. Background Technology

[0002] The retractor in endoscopic thyroid surgery is an instrument specifically designed for endoscopic thyroid surgery. Its main function is to help expose the surgical area during the operation, providing a clear field of vision and sufficient operating space. The retractor plays a crucial role in endoscopic thyroid surgery, and its design and use directly affect the safety and effectiveness of the surgery.

[0003] The reason why retractors used in endoscopic thyroid surgery come in various sizes is mainly to accommodate different anatomical structures and operational needs during the procedure. The size and location of the thyroid gland and surrounding tissues vary from patient to patient, but the size of some existing retractors is fixed. Therefore, hospitals need to purchase retractors of various sizes, which increases the cost of purchasing surgical instruments.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a retractor for endoscopic thyroid surgery in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a retractor for endoscopic thyroid surgery, which is achieved by the following specific technical means:

[0006] A retractor for endoscopic thyroid surgery includes a hook body, a support block, and a hook head. The hook body has a pair of movable grooves on both sides. Each of the movable grooves has a through groove at its top, and a locking bolt is installed within each through groove. The bottom of each of the movable grooves, directly below the through grooves, has a threaded groove. A limiting block is movably connected within each movable groove. A support block is installed on one side of the limiting block. One end of the support block has a connecting groove, and the top of the connecting groove has a second through groove, in which a second locking bolt is installed. Several slots are evenly distributed on the upper surface of the support block. A connecting block is installed at one end of the hook head, and the upper surface of the connecting block has a second threaded groove.

[0007] Furthermore, the dimensions of the locking bolt one match the dimensions of the slot.

[0008] Furthermore, the threads on the surface of the locking bolt match the threads in the threaded groove.

[0009] Furthermore, the dimensions of the connecting block and the connecting groove are matched.

[0010] Furthermore, the threads on the surface of the second locking bolt match the threads in the second threaded groove.

[0011] Furthermore, the surfaces of the hook body, support block, and hook head are all provided with a corrosion-resistant layer.

[0012] Furthermore, a wear-resistant layer is provided on the surface of the corrosion-resistant layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using the locking bolt, the slot, and the threaded groove in combination, the size of the hook is first determined according to the patient's condition. Then, the position of the support block in the movable groove is moved so that the corresponding slot on the upper surface of the support block moves below the locking bolt. Then, the locking bolt is rotated so that it passes through the slot and moves into the threaded groove, thus fixing the support block. This allows for quick and convenient adjustment of the hook size, which not only improves the practicality of the product but also reduces the purchase cost of surgical instruments.

[0015] By using the locking bolt two, threaded groove two, connecting block and connecting groove in combination, when different models of hooks are needed, the worker inserts the connecting block at one end of the corresponding model of hook into the connecting groove, and then rotates the locking bolt two to move the locking bolt two into the threaded groove two, so that the hook is fixed, thereby achieving the effect of quickly and conveniently changing different models of hooks.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a retractor for endoscopic thyroid surgery, including a hook body 1, a support block 2, and a hook head 3. The hook body 1 has a pair of movable grooves 101 on both sides. The top of each pair of movable grooves 101 is provided with a through groove 102, and a locking bolt 4 is installed in the through groove 102. The bottom of each pair of movable grooves 101 is provided with a threaded groove 103 directly below the through groove 102. A limiting block 201 is movably connected in the movable groove 101. A support block 2 is installed on one side of the limiting block 201. One end of the support block 2 is provided with a connecting groove 202. The top of the connecting groove 202 is provided with a through groove 203, and a locking bolt 5 is installed in the through groove 203. Several slots 204 are evenly provided on the upper surface of the support block 2. A connecting block 301 is installed on one end of the hook head 3. The upper surface of the connecting block 301 is provided with a threaded groove 302.

[0027] The size of the locking bolt 4 matches the size of the slot 204, and the locking bolt 4 passes through the slot 204 to fix the support block 2.

[0028] Among them, the thread on the surface of the locking bolt 4 matches the thread in the threaded groove 103.

[0029] The connecting block 301 is sized to match the connecting groove 202, and the hook 3 is connected to the support block 2 by inserting the connecting block 301 into the connecting groove 202.

[0030] Among them, the thread on the surface of the locking bolt 25 matches the thread in the threaded groove 202, and the locking bolt 25 can be moved into the threaded groove 202 to fix the hook head 3.

[0031] The surfaces of the hook body 1, support block 2, and hook head 3 are all provided with a corrosion-resistant layer, which can improve the corrosion resistance of the hook body 1, support block 2, and hook head 3.

[0032] The surface of the corrosion-resistant layer is provided with a wear-resistant layer, which can improve the wear resistance of the hook body 1, support block 2 and hook head 3.

[0033] The working principle of this embodiment:

[0034] By using the locking bolt 4, the slot 204, and the threaded groove 103 in combination, the size of the hook is first determined according to the patient's condition. Then, the position of the support block 2 in the movable groove 101 is moved so that the slot 204 at the corresponding position on the upper surface of the support block 2 moves below the locking bolt 4. Then, the locking bolt 4 is rotated so that it passes through the slot 204 and moves into the threaded groove 103, thus fixing the support block 2. This allows for quick and convenient adjustment of the hook size, improving the product's practicality and reducing the cost of surgical instruments. By using the locking bolt 5, the threaded groove 302, the connecting block 301, and the connecting groove 202 in combination, when different models of hook heads 3 are needed, the operator inserts the connecting block 301 at one end of the corresponding model of hook head 3 into the connecting groove 202, and then rotates the locking bolt 5 so that it moves into the threaded groove 302, fixing the hook head 3. This allows for quick and convenient replacement of different hook head 3 models.
