Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a deep surgical retractor with an external cold light source and a smoking function. Background Technology
[0002] Inflatable axillary endoscopic thyroid surgery has become a surgical method that can meet the needs of radical tumor removal, neck function preservation, and neck aesthetics. It avoids the disadvantages of the oral approach, which turns sterile surgery into aseptic surgery, increasing the risk of postoperative infection and damage to important maxillofacial nerves. Inflatable axillary endoscopic thyroid surgery, there is a certain period of time in which the surgeon is assisted by an assistant using a retractor to establish and maintain the surgical field. That is, after the skin is incised in the armpit, the retractor is used to create the surgical cavity. Although the existing retractors can help complete this stage of the surgery, there are still design flaws. The first is the lighting problem. First, as the surgical tunnel extends into the body, the lack of lighting in the surgical field increases the risk of surgical complications. Using external light sources increases the cost of surgical personnel. Second, because the surgical tunnel extends a long distance into the body, external light sources cannot fully meet the lighting needs. Finally, although there are various ways to add external light sources, they all involve occupying the surgeon's operating space or obstructing the surgeon's field of vision, which increases the risk of contaminating the surgical field, reduces the smoothness of the surgery, and increases the difficulty of the surgery. The second issue is the smoke from energy devices. Energy devices such as electrosurgical units and ultrasonic scalpels continuously generate smoke during operation, which can blur the surgical field, making it impossible to complete the surgery. Inhaling this smoke can also cause irreversible damage to the doctor's body. The third issue is that existing retractors have difficulties in being introduced into the body through the incision during the surgical cavity creation process. Utility Model Content
[0003] In view of this, the present invention aims to propose a deep surgical retractor with an external cold light source and a smoke-absorbing function, in order to solve the problems of lighting, smoke generated during the operation of energy instruments, and difficulty in introducing the retractor into the body through the incision in existing non-inflatable axillary endoscopic thyroid surgery.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a deep surgical retractor with an external cold light source and a smoke-collecting function, comprising a retractor body, a smoke-collecting mechanism, and a light source mechanism. The retractor body is generally L-shaped with a flat bottom and an upward-curving front end. The smoke-collecting mechanism includes a negative pressure connector, a negative pressure channel, and multiple smoke collection holes. The negative pressure connector is located on one side of the tail end of the retractor body, and the multiple smoke collection holes are all located on the bottom surface of the retractor body. A negative pressure channel is formed inside the retractor body, and the negative pressure connector communicates with the multiple smoke collection holes through the negative pressure channel. The light source mechanism includes a light source connector, a light source channel, and a light guide strip. The light source connector is located on one side of the tail end of the retractor body. Light guide strip embedding grooves are formed on both sides of the bottom surface of the retractor body. A light source channel is formed inside the retractor body, and the light source connector communicates with one end of the light guide strip embedding groove through the light source channel. A light guide strip is embedded in the light guide strip embedding groove.
[0005] Furthermore, the plurality of flue gas collection holes are evenly distributed along the length of the bottom end face of the hook body on the front half of the bottom end face of the hook body.
[0006] Furthermore, a handle is connected to one end of the hook body.
[0007] Furthermore, one side of the handle is designed with a wave-like shape.
