Description

Technical Field

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

[0002] Transoral endoscopic thyroid surgery involves making an incision in the patient's mouth, inserting a retractor through the surgical incision and extending it into the patient's neck. The retractor is then used to prop up the patient's epidermal tissue, and the doctor then performs the surgery in the space opened by the retractor.

[0003] However, since the neck lengths of different patients are different, and the existing retractor is fixed in length, it cannot be adjusted according to the patient's neck length. It cannot fully extend into and stretch the epidermal tissue of the neck of patients with longer necks, and cannot ensure sufficient field of view, which is not conducive to surgery. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a transoral thyroid retractor, which can adjust the length of the retractor according to the patient's neck length before and during surgery, providing the doctor with sufficient visual field space and facilitating surgical operations.

[0005] The technical solution adopted by the present invention is as follows: a transoral thyroid retractor, comprising a retractor body, the retractor body comprising a fixing portion for fixing the retractor and a supporting portion for supporting the epidermal tissue of the patient's neck, the fixing portion and the supporting portion being connected, the supporting portion being provided with an adjusting component that can be adjusted in position along the length direction of the supporting portion, the adjusting component comprising a support bar for extending the length of the supporting portion, one end of the support bar being located in the supporting portion, and the other end extending out of the supporting portion, the supporting portion and the support bar cooperating to support the epidermal tissue of the patient's neck.

[0006] Explanation: In the prior art, when using a retractor, a support rod is placed vertically on the operating table. The support rod is similar to an infusion stand, and one end of the fixing portion is hung on the support rod.

[0007] Principle of the technical solution:

[0008] One end of the fixing part is hung on the support rod, and the adjustment component is fine-tuned according to the length of the patient's neck, so that the total length of the support strip and the support part on the adjustment component can fully support the epidermal tissue of the patient's neck. Or, when in use, the support part supports the epidermal tissue of the patient's neck, and it is found that the epidermal tissue of the patient's neck close to the chest is not supported, the adjustment component is fine-tuned to extend the support strip to extend the length of the support part, so that the total length of the support part and the support strip can fully support the epidermal tissue of the patient's neck. The fixing part is lifted up again, and the fixing part drives the supporting part and the support strip on the support part to move upward, exposing the internal space of the patient's neck.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The adjustment component of the present invention can not only extend the length of the support part and cooperate with the support part to fully support the patient's neck epidermal tissue, but can also be adjusted during use to assist in extending the length of the support part and cooperate with the support part to fully support the patient's neck epidermal tissue, so that the length of the retractor can be adjusted according to the patient's neck length before surgery, and the length of the retractor can be adjusted more accurately according to the actual situation after being inserted into the patient's neck during surgery, providing doctors with sufficient visual space during operation and facilitating surgical operations.

[0011] 4. The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut.

[0012] In this solution, the hand is placed on the second limit plate and the second limit plate is pushed to move along the length direction of the support part. When the second limit plate moves, the support bar is driven to move along the length direction of the support part, that is, the support part continues to be extended, so that the sum of the length of the support part and the length of the support bar outside the support part is approximately equal to the length of the patient's neck that needs to be supported. Stop pushing the second limit plate, the support part stops moving, the elastic part is locked in the slot, the elastic part limits the second limit plate, thereby limiting the position of the support bar, and the support bar and the support part cooperate to provide stable support for the epidermal tissue of the patient's neck.

[0013] Beneficial effect: the length of the placement slot is greater than the width of the accommodating slot, so that the accommodating slot can accommodate the first limit plate and the support bar, and the lower surface of the upper card slot of the accommodating slot can also abut against the support bar for limitation. Since the lower surface of the first limit plate fits with the inner surface of the bottom of the placement slot, and the upper surface fits with the support bar, when the support bar is abutted and limited, the first limit plate is also indirectly limited. Since the first limit plate is connected to the second limit plate through the connecting plate, the lower surface of the second limit plate fits with the upper surface of the card slot, when the first limit plate is limited, the second limit plate is also indirectly limited. The cooperation of the first limit plate, the connecting plate, the second limit plate, the support bar, the elastic part, and the card slot can adjust the position of the support bar along the length direction of the support part, that is, adjust the length of the support bar extending out of the support part.

[0014] As a preferred embodiment of the present invention, the elastic member includes an elastic first connecting strip and a clamping block connected to the first connecting strip, and the clamping block can be clamped into the clamping slot.

[0015] In this solution, when the hand pushes the second limit plate to move along the length direction of the support part, the second limit plate drives the first connecting strip to move along the length direction of the support part. Since the card block is stuck in the card slot, when the first connecting strip moves, the elastic first connecting strip also swings along the width direction of the support part, driving the card block to swing along the width direction of the support part, so that the card block slides out of the card slot and slides into the next card slot. When the hand stops pushing the second limit plate, the first connecting strip stops swinging along the width direction of the support part, and the card block slides into the card slot.

[0016] Beneficial effect: The elastic first connecting strip, the card block and the card slot cooperate to limit the first limiting part after the position is moved, and the support strip is limited by the first limiting part, thereby ensuring that the support strip stably cooperates with the support part to provide stable support for the patient's neck.

[0017] As a preferred embodiment of the present invention, the upper surface of the second limiting plate and the upper surface of the supporting portion are located on the same horizontal plane.

[0018] Beneficial effect: Compared with the situation where the upper surface of the second limiting plate is located above the upper surface of the support part, this design can make the thickness of the support part as thin as possible, that is, the thickness of the support part extending into the patient's neck is as thin as possible. When the fixing part drives the support part to move upward, the height of the exposed operating space is as high as possible, that is, the internal space of the patient's neck can be fully exposed.

[0019] As a preferred embodiment of the present invention, the upper surface of the second limiting plate is provided with anti-slip stripes.

[0020] Beneficial effect: the anti-slip stripes can prevent slipping and facilitate the operator to push the second limit plate. BRIEF DESCRIPTION OF THE DRAWINGS
