Endoscopic surgery cavity builder

Abstract

The invention relates to the field of medical instruments, in particular to an endoscope surgery cavity builder. The cavity builder comprises an endoscope lens protection part and a supporting part, wherein the endoscope lens protection part is connected with the supporting part in a sliding mode and is attached to the supporting part; the supporting part is used for establishing an operation space; the endoscope lens protection part is provided with a through cavity for an endoscope lens to penetrate through; and after the operation space is established, the endoscope lens protection part supports the supporting part, and the endoscope lens penetrates through the cavity and moves to a target position. The cavity builder has the beneficial effects that the established operation space is supported by the supporting part and the endoscope lens protecting part, and inflation is not needed, so that inflation complications, especially gas embolism, are avoided; the operation space communicates with the outside, and the endoscope lens is protected by the endoscope lens protection part from being polluted, so that the view definition of the operation space is improved; and the structure is simple, the operation steps are few, the surgical operation time is shortened, the flap rupture risk is reduced, and the surgical safety is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a cavity builder for laparoscopic surgery. Background technique [0002] Thyroid cancer is the most common malignant tumor of the endocrine system, and surgery is its most effective treatment. Patients have higher and higher demands for beauty; laparoscopic thyroid surgery has gradually gained recognition from patients due to its good cosmetic effect. The development of laparoscopic thyroid surgery has different indications and contraindications depending on the surgical approach, and the difficulty of the operation is also different. It is important to choose the most suitable surgical method for patients while ensuring the effect of surgical treatment. Doctor's new request. [0003] Surgical approach [0004] 1.1. Small incision in front of the neck and oral mirror-assisted thyroid surgery approach: Generally, a 1-3 cm incision is made in the front of the neck, and the ope...

Problems solved by technology

Disadvantages: The surgical space is narrow, and it is difficult to deal with the upper pole of the thyroid vessels and the superior laryngeal nerve; there is chopsticks effect in the operation of surgical instruments; the surgical angle of view is free from top to bottom, which is opposite to the traditional surgical sequence, and the recurrent laryngeal nerve cannot be observed from the side , high requirements for the operator's clinical experience and anatomical theory

Laparoscopic surgery for benign thyroid tumors has been affirmed, but it is controversial in the treatment of thyroid cancer due to the thoroughness of laparoscopic surgery and intraoperative tumor dissemination.

Secondly, compared with the common complications of traditional open thyroid surgery: intraoperative or postoperative bleeding, superior laryngeal nerve injury, recurrent laryngeal nerve injury, hypoparathyroidism, trachea and esophagus injury, etc.; Symptoms: subcutaneous emphysema, hypercapnia, gas embolism, etc.; in addition, endoscopic equipment is expensive

[0011] Summary: The establishment and maintenance of the existing transoral vestibular approach endoscopic thyroid surgery space needs to be filled with carbon dioxide gas to assist. Because the space is airtight, there will be problems: the smoke cannot be removed in time, resulting in unclear vision and frequent wiping of the lens; it is easy to cause high Severe complication of hypercapnia and even pulmonary gas embolism

At present, the difficulty in establishing surgical operation space and the prevention of inflation-related complications have become the current clinical bottlenecks.

Clinically, there is no gas-free cavity construction equipment for endoscopic thyroid surgery through oral vestibular approach
