Description

Technical Field

[0001] The utility model designs a single-hole thoracoscope fixator, which relates to a surgical auxiliary instrument. Background Art

[0002] Single-port thoracoscopic technology refers to the use of only a small incision (usually between 2-5 cm) in the chest. After the incision skin tissue retractor is placed, the laparoscope and surgical instruments are used through the same surgical incision to complete various intrathoracic surgeries, including lung wedge resection, lobectomy, lung segmentectomy, etc. (with increasing difficulty). Double-port thoracoscopic technology refers to making two holes in the human body, one hole is about 1 cm in diameter, and the Trocar puncture device is placed for the entry and exit of the thoracoscope; the other hole is about 3 cm long, and after the incision skin tissue retractor is placed, it is used for the entry and exit of surgical instruments, and the diseased lung tissue is removed through this hole. Compared with double-port or multi-port thoracoscopic technology, single-port thoracoscopic technology has the advantages of more direct vision, better lung exposure, less postoperative pain, faster recovery, shorter hospitalization time, smaller and less obvious postoperative incision scars, etc. The incision skin tissue retractor commonly used in clinical practice is a disposable silicone type, such as Figure 1 As shown, there are various specifications, which have the functions of non-damaging retraction of surgical incisions, protection of incision tissues, expansion of surgical channels and exposure of surgical fields.

[0003] The current problem with single-port thoracoscopic surgery is that when using an incision skin tissue retractor, the laparoscope has no force support point in the hole of the retractor. During the entire operation, the surgeon can only support and fix the mirror to ensure the stability of the lens. If the operation time is very long, the surgeon will be very tired and exhausted, and the stability of the mirror cannot be guaranteed, which affects the quality of the laparoscope image. There are also incision skin tissue retractors with laparoscope operation holes in current applications (such as Figure 2 As shown in the figure, a laparoscope hole is designed within the original dilator aperture, but this reduces the instrument operation space to a certain extent. At the same time, when the laparoscope is operated in multiple directions to observe the force, it is easy to pull the main body of the dilator, affecting the patient's tissue incision. At the same time, the position is easily limited when changing the observation angle. Utility Model Content

[0004] In order to solve the above problems, the utility model designs a single-port thoracoscopic fixator that can be used in conjunction with an incision skin tissue retractor and expander.

[0005] The technical solution of the utility model is: a single-port thoracoscopic fixator, which is characterized in that it has a circular ring-shaped main body, an elastic band is provided on the edge of the circular ring-shaped main body, and both ends of the elastic band are fixedly connected to the circular ring-shaped main body.

[0006] Furthermore, the annular main body of the single-port thoracoscopic fixator of the present invention may be an elastic integrated annular structure.

[0007] Furthermore, the annular body of the single-port thoracoscopic fixator of the present invention can also be a split annular structure, wherein the annular body is composed of a semi-annular left body and a semi-annular right body, wherein the corresponding ends of the semi-annular left body and the semi-annular right body are movably connected by a rotating shaft mechanism, and the corresponding other ends of the semi-annular left body and the semi-annular right body are movably connected by a snap mechanism, and the elastic band is arranged on the semi-annular left body or the semi-annular right body, and the two ends of the elastic band are fixedly connected to the semi-annular left body or the semi-annular right body.

[0008] The single-port thoracoscopic fixator designed by the utility model is used in conjunction with an incision skin tissue retractor and expander. During use, the annular main body is put under the upper surface of the incision skin tissue retractor and expander, with the elastic band at its edge exposed to the outside, the laparoscope used for surgery is inserted into the hole of the elastic band, and then the laparoscope (through the elastic band) is pulled into the expander hole to perform surgery. With the interaction between the tension of the elastic band and the supporting force of the inner hole wall of the expander, the laparoscope will be close to the inner hole wall of the expander, generating a supporting force for the doctor holding the laparoscope, thereby achieving the effects of saving effort, not occupying the space of the center hole of the expander, and freely changing the angle of the laparoscope.
