Drag hook for endoscopic thyroid surgery

Abstract

The invention discloses a drag hook for endoscopic thyroid surgery, which belongs to the field of surgical instruments, and comprises a catheter and a support component fixed at one end of the catheter, a puncture outfit joint is fixed at one end of the catheter far away from the support component, the puncture outfit joint is matched with a port of a puncture outfit tube sleeve, and an instrument through hole is formed in the catheter. An air inlet pipeline and an exhaust pipeline are arranged in the catheter, the supporting assembly comprises a supporting framework, a guiding operation cavity is formed in the supporting framework, three grooves are evenly fixed to the outer wall of the supporting framework at equal angles, air bags are connected into the grooves in a glued mode, and two drag hook pieces are fixed to the sides, away from the supporting framework, of the air bags. The device does not need an additional puncture hole, is used together with a puncture hole of an endoscopic surgical instrument, does not cause nerve injury and muscle injury due to no mechanical puncture operation, is high in safety coefficient, adjustable in surgical cavity building angle and range and convenient to operate, has a market prospect and is suitable for popularization.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a retractor for endoscopic thyroid surgery. 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. Continuous use of carbon dioxide will cause hypercapnia, and continuous pressure will cause subcutaneous emphysema, and even cause serious complications ...

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.

[0003] 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 and cause serious consequences. However, more endoscopic incisions are required for the group, and the instrument will block part of the endoscopic field of view during the operation, which will affect the operator's operation: pulling the muscle group with silk thread has limited exposure and cannot move the pulling position

However, the existing retractor for endoscopic thyroid surgery still has the disadvantages of small field of view, poor flexibility, and inconvenient use. Therefore, we propose a retractor for endoscopic thyroid surgery to solve the above problems
