Laparoscopic thyroid surgery retractor

Abstract

The invention discloses a wire retractor for endoscopic thyroidectomy, which is applicable to surgical field exposure of the endoscopic thyroidectomy. The wire retractor comprises a supporting body, wherein muscle fixing heads are arranged at two ends of the supporting body; the supporting body is an elastic supporting bar, two ends of the elastic supporting bar are connected with the muscle fixing heads by virtue of spherical hinges; and notch tanks for fixing muscle are formed in the muscle fixing heads, and the notches of the notch tanks are formed toward two ends. According to the wire retractor, an approximate semispherical surgical operating space is established by smartly utilizing the muscle group restoring force for separating the anterior cervical muscle group, rather than establishing a manual inflation surgical field, wherein the elastic supporting bar is divided into a long section and a short section by a hinge column, and two parts of the elastic supporting bar are folded at the hinging column in the using process to generate a larger operating space, so that the actual operation becomes practical. The wire retractor is simple and practical in structure, closely combines the characteristics of endoscopic thyroidectomy, and can acquire space and surgical field necessary to a surgery by revolutionarily using mechanical support instead of manual support.

Description

technical field [0001] The invention belongs to medical equipment, and in particular relates to a surgical retractor used for opening an endoscopic thyroid surgical field. Background technique [0002] Surgical field exposure in endoscopic thyroid surgery is an important step. Anatomically, the thyroid gland is located behind the anterior cervical muscles, on both sides of the trachea, and in a potential cavity anterior to the jugular sheath. The first step in the operation is to expand this potential cavity into a real cavity. The conventional method is to insert a puncture device through a tunnel dilator, and then pass carbon dioxide to maintain a certain pressure to free the fascia below the platysma. After the gap, retract the anterior neck muscles by means of skin puncture retractors or transdermal suspension wires to expose the thyroid tissue. [0003] Continuous use of carbon dioxide will cause hypercapnia, and continuous pressure will cause subcutaneous emphysema, ...

AI Technical Summary

Problems solved by technology

And the use of the skin puncture retractor will cause damage to the neck skin, and subcutaneous, muscle, and blood vessel damage and bleeding may occur during the puncture process, which will affect the operation field.

The method of using the transdermal suspension wire also has damage to the skin of the neck, and the position is fixed and should not be adjusted. There is also damage to the blood vessels, which may affect the surgical field.

[0004] At the same time, both the skin puncture retractor and the transdermal suspension wire require a full-time assistant to be responsible for continuous maintenance during the entire operation process. The assistant's unskilled operation will easily hinder the surgeon's operation, causing serious consequences
