Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a thyroid retractor. Background Art

[0002] During thyroidectomy, the thyroid gland needs to be separated from the tissue and the lesion needs to be pulled up before surgical removal. This treatment requires special tools to complete. The commonly used tool in clinical practice is the thyroid retractor. Medical staff use the thyroid retractor to pull the tissue around the thyroid gland to fully expose it so that doctors can perform surgical operations.

[0003] The Chinese utility model patent with publication number CN203107187U discloses a thyroid retractor, including: a connecting rod; a head fixed and integrated with one end of the connecting rod; a handle fixedly connected to the other end of the connecting rod; and a protective cover mounted on the head and the connecting rod. The thyroid retractor in the above technology can achieve traction of the thyroid incision. However, the length of the head pulled by the thyroid retractor is limited. Since the depth and location of the surgical incision of different patients are different, a single limited retractor design often cannot meet the surgical needs of different patients. In addition, the head pulled by the thyroid retractor is a right-angle structure. When medical staff use the thyroid retractor for traction, the head of the right-angle structure is easy to form a right-angle contact with the skin, which not only increases the friction and pressure on the skin, but also may cause damage to the incision skin, thereby affecting the smooth progress of the operation and postoperative recovery.

[0004] Therefore, it is urgent to develop a new type of thyroid retractor that is easy to flexibly adjust the extension length of the retractor to adapt to the anatomical characteristics and surgical needs of different patients. Utility Model Content

[0032] Embodiment 1:

[0033] A thyroid retractor comprises a handle 1 and a retractable hook body 2 arranged at one end of the handle 1. The retractable hook body 2 comprises a first connecting rod 21 connected to one end of the handle 1, and a first fixing hook 22 is vertically connected to the end of the first connecting rod 21 away from the handle 1. An extension hook 23 is slidably sleeved on the end of the first fixing hook 22 away from the first connecting rod 21, and a locking assembly 24 for locking the moving position of the extension hook 23 is also provided on the first fixing hook 22.

[0034] By providing an extension hook 23 and a locking assembly 24 that are slidably sleeved on the first fixing hook 22, medical staff can adjust the length of the extension hook 23 according to the actual needs of the operation, so that the thyroid retractor can adapt to the anatomical characteristics and surgical needs of different patients, thereby improving the flexibility and adaptability of the thyroid retractor during surgery.

[0035] Embodiment 2:

[0036] A thyroid retractor, such as Figure 1 As shown, it includes a handle 1 and a retractable hook body 2 arranged at one end of the handle 1.

[0037] The handle 1 of this embodiment is provided with a plurality of finger grooves 11, which are distributed in a linear array. The provision of the finger grooves 11 facilitates medical personnel to hold the thyroid retractor more stably, reduces operational errors caused by handle slippage or rotation during surgery, and allows the most suitable groove position to be selected to hold the handle 1 according to hand shape and habit, thereby improving operational stability and comfort.

[0038] The end of the extension hook 23 of this embodiment away from the first fixing hook 22 is in an arc structure that fits the skin. The design of the arc structure conforms to the physiological curve of human skin, so that the extension hook can fit the skin more naturally when pulling, reducing friction and pressure with the skin, thereby better protecting the incision skin.

[0039] like Figure 2 As shown, the locking assembly 24 of this embodiment includes a limiting groove 241 opened at the bottom of the first fixing hook 22 and a limiting block 242 slidably disposed in the limiting groove 241 and fixedly connected to the extension hook 23. A tightening bolt 243 is disposed on the limiting block 242, and a knob 244 is installed at one end of the tightening bolt 243 away from the limiting groove 241. The medical staff only needs to loosen or tighten the locking bolt 243 through the knob 244 to make the limiting block 242 move or fix laterally in the limiting groove 241, so as to flexibly adjust the length of the extension hook 23.

[0040] The first fixing hook 22 of this embodiment is provided with a scale line 221, so that medical staff can accurately understand the extension length of the extension hook 23 relative to the first fixing hook 22, which helps medical staff to accurately adjust the length of the extension hook 23 according to actual needs during surgery, ensuring the best surgical exposure effect.

[0041] Embodiment 3:

[0042] A thyroid retractor comprises a handle 1, a retractable hook body 2 arranged at one end of the handle 1 and a fixed hook body 3 arranged at the other end of the handle 1.

[0043] like Figure 3 As shown, the fixed hook body 3 of this embodiment includes a second connecting rod 31 connected to the handle 1 and a second fixed hook 32 vertically arranged at an end of the second connecting rod 31 away from the handle 1. The length of the second fixed hook 32 is not greater than the length of the first fixed hook 22. When there is no need to adjust the telescopic length of the telescopic hook body 2, medical staff can directly use the fixed hook body 3 for pulling, which is convenient for surgical operations.

[0044] Embodiment 4:

[0045] This embodiment provides a thyroid retractor, which includes a handle 1, a fixed hook body 3 fixedly arranged at one end of the handle 1, and a retractable hook body 2 arranged at the other end of the handle 1 for fitting the thyroid incision skin. The combined design of the handle 1, the fixed hook body 3 and the retractable hook body 2 enables medical staff to operate quickly and accurately, reduces unnecessary steps during the operation, and thus improves the efficiency of the operation.

[0046] In order to improve the flexibility and adaptability of the use of the thyroid retractor of this embodiment, unlike the existing thyroid retractor, the retractable hook body 2 includes a first connecting rod 21 fixedly connected to the end of the handle 1 away from the fixed hook body 3, a first fixed hook 22 fixedly connected to the end of the first connecting rod 21 away from the handle 1, an extension hook 23 slidably sleeved on the end of the first fixed hook 22 away from the first connecting rod 21, and a locking assembly 24 provided at the end of the extension hook 23 close to the first fixed hook 22 for locking the position of the extension hook 23. By providing the extension hook 23 slidably sleeved on the fixed hook and the locking assembly 24, medical staff can adjust the length of the extension hook 23 according to the actual needs of the operation, so that the thyroid retractor can adapt to the anatomical characteristics and surgical needs of different patients, and improve the flexibility and adaptability of the thyroid retractor during surgery.

[0047] In order to improve the comfort of using the thyroid retractor of this embodiment, the end of the extension hook 23 away from the first fixing hook 22 is in an arc structure. The design of the arc structure is more in line with the physiological curve of human skin, so that the extension hook 23 can fit the skin more naturally when pulling, reducing friction and pressure with the skin, thereby better protecting the incision skin.

[0048] For easy operation, a finger groove 11 is provided on the handle 1. The design of the finger groove 11 allows the fingers of medical staff to be more naturally embedded therein, thereby increasing the contact area between the handle 1 and the fingers, helping the doctor to hold the thyroid retractor more stably and reducing operational errors caused by the handle 1 slipping or rotating during surgery.

[0049] In order to adapt to different hand shapes and operating habits, multiple finger grooves 11 are provided, and the multiple finger grooves 11 are distributed in a linear array. Since each medical staff has different hand shapes and operating habits, the design of multiple finger grooves 11 can better adapt to the needs of different medical staff, so that medical staff can choose the most suitable position of the finger groove 11 to hold the handle 1 according to their own hand shapes and habits, thereby improving the stability and comfort of operation.

[0050] To facilitate adjustment, the locking assembly 24 includes a limiting groove 241 opened at the bottom of the first fixing hook 22, a limiting block 242 that moves laterally in the limiting groove 241 and is fixedly connected to one end of the extension hook 23 close to the first fixing hook 22, and a tightening bolt 243 arranged on the limiting block 242, and the limiting block 242 is fixedly connected to the limiting groove 241 by the tightening bolt 243; the combined design of the limiting groove 241, the limiting block 242 and the tightening bolt 243 enables medical staff to move or fix the limiting block 242 laterally in the limiting groove 241 by only loosening or tightening the tightening bolt 243, so as to flexibly adjust the length of the extension hook 23.

[0051] Preferably, in order to facilitate the operation of the tightening bolt 243, a knob 244 is fixedly installed at one end of the tightening bolt 243 away from the limiting groove 241. The design of the knob 244 enables medical staff to operate the tightening bolt 243 more conveniently, thereby quickly locking or loosening the limiting block 242.

[0052] Preferably, in order to provide an accurate measurement reference, a scale line 221 is provided on the first fixing hook 22. The design of the scale line 221 enables medical personnel to accurately understand the extension length of the extension hook 23 relative to the first fixing hook 22, thereby helping medical personnel to accurately adjust the length of the extension hook 23 according to actual needs during surgery, ensuring the best surgical exposure effect.

[0053] When it is necessary to adjust the length of the retractable hook body 2, the medical staff can first loosen the tightening bolt 243 to release the fixation of the tightening bolt 243 to the limit groove 241 and the limit block 242; then make the extension hook 23 slide horizontally on the first fixed hook 22. Since the limit groove 241 is fixedly connected to the extension hook 23, the limit block 242 will also slide horizontally in the limit groove 241 synchronously while the extension hook 23 slides. When the extension hook 23 is adjusted to a suitable position, the tightening bolt 243 is tightened so that the tightening bolt 243 is gradually screwed in until it penetrates the limit block 242 and abuts against the bottom wall of the first fixed hook 22 to form a lock, so that the limit block 242 can be fixed in the limit groove 241. At this time, by locking the limit block 242 and the limit slot 241, it can be ensured that the extension hook 23 will not slide or shift on the first fixed hook 22 when in use. At the same time, the design of the limit slot 241 and the limit block 242 can ensure that the extension hook 23 will not slide off the first fixed hook 22.

[0054] The fixed hook body 3 of this embodiment includes a second connecting rod 31 connected to the handle 1 and a second fixed hook 32 vertically arranged at an end of the second connecting rod 31 away from the handle 1. The length of the second fixed hook 32 is not greater than the length of the first fixed hook 22. When there is no need to adjust the telescopic length of the telescopic hook body 2, medical staff can directly use the fixed hook body 3 for pulling, which is convenient for surgical operations.

[0055] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
