Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a thyroid surgery incision protection and expansion device. Background Art

[0002] During thyroid surgery, an ultrasonic scalpel or an electric scalpel is used for the operation, and the ultrasonic scalpel will cause burns to the skin on both sides of the incision, resulting in scars after the incision is sutured. Open thyroidectomy surgery requires that the surgical field of view be fully exposed after the neck incision is opened. In the prior art, a special retractor for the incision is generally used. The special retractor generally requires the person who retracts the retractor to be located at the head end of the patient, and each hand holds a retractor, one to pull toward the head end, and the other to pull open the premenstrual band muscle. The fixation is inconvenient and requires two people to operate at the same time and cooperate with each other. The surgical efficiency is relatively low in terms of use effect. The retractor can easily cause damage to the thyroid and other parts during the pulling process. This conventional method requires more medical staff and easily consumes medical resources. In view of this, we propose a thyroid surgery incision protection and expansion device. Utility Model Content

[0003] The purpose of the utility model is to provide a thyroid surgery incision protection and expansion device, which solves the problem of scars on the skin on both sides of the incision after suturing in the prior art.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] A thyroid surgery incision protection and expansion device, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the neck support frame 1 includes a neck support frame 1, which can position the patient's head to maintain a preset state. The neck support frame 1 is provided with a traction mechanism 2, which can pull the skin on both sides of the incision to open the incision and facilitate operation on the subcutaneous tissue.

[0028] Specifically, the traction mechanism 2 includes two patches 201, which are arranged on the surface of the neck support 1. The side of the two patches 201 away from the neck support 1 is a medical tape and covered with release paper. The patches 201 can be adhered to the skin of the patient's affected area. The inner sides of the two patches 201 are detachably connected to a traction rope 202. The end of the traction rope 202 can be connected to the side of the patch 201 away from the medical tape by tying, clamping, or pasting. The traction rope 202 structure can pull the patch 201, thereby pulling and traction the incised skin after surgery, so that the incision is opened to facilitate operation and avoid burns on the skin on both sides of the incision. At the same time, the detachable connection between the patch 201 and the traction rope 202 allows the patch 201 to be replaced after use. The end of the traction rope 202 away from the patch 201 is fixedly connected to a piston rod 203, and the outer side of the piston rod 203 is slidably connected to a piston cylinder 204. The piston cylinder 204 is fixedly connected to the inside of the neck support 1. The piston rod 203 and the piston cylinder 204 can cooperate with each other to actively control the pulling force of the traction rope 202 by inflating the inside of the piston cylinder 204, thereby controlling the opening angle of the blade. At the same time, the structure of the piston rod 203 can be fine-tuned by the amount of inflation, so that the traction force can be accurately controlled. An air inlet nozzle 205 is fixedly connected to one side of the piston cylinder 204. The air inlet nozzle 205 structure can facilitate the inflation of the inside of the piston cylinder 204.

[0029] Furthermore, a guide rod 206 is connected to the inside of the neck brace 1, around which the traction rope 202 is wound, providing support. The end of the piston rod 203 is made of elastic material, allowing it to move within the irregularly shaped neck brace 1. The guide rod 206 steers the traction rope 202, allowing one end of the traction rope 202 to move toward the patch 201 along with the piston rod 203 while the other end moves toward the guide rod.

[0030] It is worth noting that a one-way valve is fixedly connected to the interior of the air inlet nozzle 205. The one-way valve structure can prevent gas leakage inside the piston cylinder 204. One end of the air inlet nozzle 205 passes through the neck support 1 and the piston cylinder 204 and is connected to the interior of the piston cylinder 204. The outside of the air inlet nozzle 205 can be connected to an inflation device, such as an ear bulb, a disposable syringe, or a foot-operated inflation pump. The ear bulb is convenient for sterilization, while the disposable syringe is a sterile structure, making it easier for the nurse to inflate the interior of the piston cylinder 204 during surgery. In addition, the foot-operated inflation pump can be operated by one person, allowing the surgeon to operate independently and precisely control the patch 201 as needed.

[0031] Furthermore, a return spring 209 is fixedly connected to the end of the piston rod 203. This structure facilitates the reset of the piston rod 203, allowing the patch 201 to rebound after the operation, facilitating the suturing operation. An exhaust pipe 210 is fixedly connected to the middle of the side of the piston cylinder 204, and a sealing plug 211 is movably connected to the exhaust pipe 210. The exhaust pipe 210 structure facilitates the discharge of gas inside the piston cylinder 204.

[0032] In addition, two limiting grooves 212 are provided on the surface of the neck support bracket 1. The two limiting grooves 212 are provided on both sides of the patch 201. A sealing cover 213 is clamped inside the limiting groove 212. The patch 201 is provided with two sealing covers 213, and the sealing cover 213 can seal and limit the patch 201 when not activated, thereby preventing the patch 201 from falling off when not in use.

[0033] Example 2

[0034] like Figure 1-Figure 4 As shown, based on Example 1, a protective mechanism 3 is provided on the outside of the neck support 1; the protective mechanism 3 can protect the patient's neck and head, so that the suture area can be protected after the operation is completed.

[0035] In this embodiment, the protective mechanism 3 includes a slide 301 provided on the neck support 1. A protective frame 302 is slidably connected to the slide 301. The protective frame 302 can slide within the slide 301 to adjust its position. A protective block 303 is movably connected to the center of the protective frame 302. The protective block 303 can be installed and removed. The protective block 303 is made of a flexible material, which protects the sutures while avoiding excessive pressure.

[0036] On this basis, the protective frame 302 is rotatably connected to a limiting rod 304, and torsion springs 305 are fixedly connected on both sides of the limiting rod 304. The limiting rod 304 structure can block the protective block 303 to prevent the protective block 303 from falling. At the same time, the torsion spring 305 structure can provide pressure for the protective block 303.

[0037] To use the thyroid surgery incision protection and dilation device of the present invention, the sterilized neck brace 1 is first placed over the patient's neck, while the vent is sealed with a sealing plug 211. The sealing cover 213 is then removed and discarded, and the sterile patch 201 is adhered to the skin on both sides of the incision to be made. After the skin is incised, air is inflated into the piston cylinder 204 via an inflator. As the air pressure within the piston cylinder 204 continues to increase, the piston rod 203 is pushed outward, stretching the return spring 209 as it moves. As the piston rod 203 moves, it pulls the patch 201 toward each side via the traction cord 202, thereby expanding the incision and enlarging the surgical field of view. When the surgery is complete, the sealing plug 211 is opened, and the air inside the piston cylinder 204 is discharged through the vent pipe 210. The stretched return spring 209, in turn, elastically forces the piston rod 203 in the opposite direction until it returns to its original position. After the piston rod 203 is reset, the traction rope 202 loses its tension, loosening the skin on both sides of the incision. The incision shrinks, allowing suturing to proceed. After suturing is complete, the protective frame 302 can be installed. After rotating the limiting rods 304 to the sides, the protective block 303 can be inserted into the protective frame 302. After releasing the limiting rods 304, they rotate toward each other under the elastic action of the torsion springs 305, securing the protective block 303.
