Description

Chamber mirror protective sheath that possesses automatic smoking function

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a chamber mirror protective sheath that possesses automatic smoking function.

Background

In recent years, with the development of thoracic surgical techniques, the application of full thoracoscopic surgery is gradually increased, and by using modern camera technology and corresponding surgical instrument equipment, complex operations in the thoracic cavity can be completed through a small incision in the chest wall. The diameter of an incision of the endoscopic surgery is generally 2-10 cm, and the surgical operation can be performed by means of various modern high-tech surgical equipment. The endoscopic surgery requires doctors to master better operation technology due to small incision, and special instruments are required to accelerate the surgical process, wherein the electrocoagulation hook, the electric knife, the ultrasonic knife and other devices are medical devices which are commonly used in the endoscopic surgery process. Most of the devices cut tissues by high-frequency current or ultrasonic waves, and the high-energy surgical devices can melt the cut tissues, can quickly cut and separate surface tissues and have excellent effects. However, the surgical instruments such as the electrocoagulation hook or the ultrasonic knife inevitably generate harmful smoke in the process of cutting and coagulating blood in the surgical operation, the operation smoke influences the operation visual field, the risk and the time of the operation are increased, and the formed harmful gas simultaneously influences the health of patients and medical care personnel. Thus, it is necessary to use special devices to remove surgical smoke during surgery.

The current method for treating harmful gas generated by the electrotome is as follows:

1. an operator uses a common electrotome with a smoke suction device, but the suction device of the electrotome has limited capacity of sucking smoke, and a large amount of smoke can be blown out to cause injury to medical staff in the operation; moreover, after the smoke suction device is integrated on the electrotome, the flexibility of the medical staff for operating the electrotome is deteriorated, which is not beneficial to the implementation of fine surgery;

2. the surgical assistant attracts the surgical assistant by using the attraction device, and the surgical assistant is needed to help, so that a lot of people are involved in the operation, the operation is complicated, and the operation is easily interfered.

Therefore, an instrument for attracting the smoke generated during the electrotome operation is needed, so that the harm of the smoke to medical staff is eliminated, the number of surgical assistants is reduced, and the labor is saved.

The Chinese patent application: CN103111007A discloses an aspirator for endoscopic surgery. Specifically, the aspirator for endoscopic surgery comprises a holding part, a suction tube body part and a suction tube top end part, wherein the suction tube top end part comprises a top end body part and a top convex surface, the top convex surface is provided with a top suction hole, the suction tube top end part is also provided with a top-side suction hole, one part of opening of the top-side suction hole is positioned on the top convex surface, the other part of opening is positioned on the side surface of the top end body part, and the top end body part can be optionally provided with a side suction hole.
