Description

Technical Field

[0001] The invention relates to the technical field of thyroid surgery, and in particular to a subclavian approach sternocleidomastoid muscle retractor. Background Art

[0002] The subclavian approach was first reported by Japanese scholar Shimizu in 1998 and is mainly used for laparoscopic thyroid surgery. This approach establishes an operating space through the gap between the sternocleidomastoid muscle sternal head and clavicular head, and has the advantages of concealed incision and beautiful postoperative appearance.

[0003] In the current subclavian approach, the obstruction of the sternocleidomastoid muscle often makes it difficult to clear the central lymph nodes, especially in the lower area. It is usually necessary to sever some muscles to expose the surgical field. The traditional method requires severing the anterior cervical strap muscles, which can easily cause complications such as foreign body sensation in swallowing and skin numbness after surgery, and may damage the branches of the cervical nerve.

[0004] In current surgical practice, since the traction range of the suspension retractor dedicated to surgery is limited and fixed, its traction adjustment of the muscle position at the incision is difficult to meet the changing needs of surgical practice. There is an urgent need for a sternocleidomastoid retractor that can be manually operated by medical staff to assist the suspension retractor in pulling the muscles to create enough space for surgical operations. Summary of the invention

[0005] The present invention provides a subclavian approach sternocleidomastoid muscle retractor, which specifically comprises: The hook body is U-shaped as a whole, and one end of the hook body is fixedly connected to the handle body; a smoking passage is provided inside the hook body, and the smoking passage runs through the entire hook body; a smoking port connected to the smoking passage is provided at one end of the hook body away from the handle body; the smoking port is located on the outside of the hook body; and a connection interface connected to the smoking passage is provided at one end of the hook body where the handle body is installed.

[0013] Preferably, the hook body comprises a first section and a second section; an end of the first section away from the handle body is provided with an inclined surface inclined at an angle of 45° to the central axis of the first section, and a rotating axis is provided on the inclined surface of the first section; an end of the second section away from the smoking port is provided with an inclined surface inclined at an angle of 45° to the central axis of the second section, and the inclined surface of the second section coincides with the inclined surface of the first section, and the second section is connected to the first section via the rotating axis.

[0014] Beneficial Effects

[0015] In the present invention, 1. By using this sternocleidomastoid retractor, the retractor body can manually adjust the pulling position of the sternocleidomastoid muscle. In combination with the suspension retractor, the surgical field can be fully exposed without disconnecting the anterior cervical strap muscles, thus avoiding complications such as postoperative foreign body sensation in swallowing and skin numbness caused by disconnecting the muscles in traditional methods, and reducing the risk of injury to the cervical nerve branches. 2. Through the cooperation of the tapered connection interface and the threaded fastener, the suction tube can be gradually tightened to avoid slipping problems and improve the collaborative efficiency of surgical instruments; 3. The smoking channel runs through the main body of the retractor. Its hose material can absorb the impact of airflow, reduce the disturbance to the sternocleidomastoid muscle, and work with the suspension retractor to maintain muscle stability, providing a clear field of vision for central lymph node dissection. 4. The main body of the retractor adopts a rotatable U-shaped structure, and the L-shaped shape can be adjusted through the rotating axis to meet the needs of different surgical angles, breaking through the limitations of the fixed traction range of traditional suspension retractors.
