Description

TECHNICAL FIELD

[0001] The present application relates to a laparoscopic surgery auxiliary device. BACKGROUND

[0002] Single-port laparoscopic surgery is a new minimally invasive treatment method through the umbilical orifice or vaginal incision path to place instruments for observation and cutting operation. Since the surgical instruments are all inserted into the abdominal cavity from a narrow incision, the operation difficulty is significantly increased, especially the abdominal organs such as intestinal tube and omentum often interfere with the surgical field, which further increases the operation difficulty. More seriously, when removing uterine fibroids and ovarian tumors, tumor rupture often occurs, causing iatrogenic tumor dissemination and metastasis, which seriously threatens the patient's life. Therefore, it is of great significance to protect the surgical field of single-port laparoscopic surgery, reduce the interference of adjacent intestinal tube, and prevent iatrogenic tumor metastasis.

[0003] At present, the method of preventing iatrogenic tumor dissemination and metastasis by means of multi-port laparoscopic technology of abdominal wall increases the abdominal wall trauma. The tumor-free defense of single-port laparoscopic surgery is only limited to the tumor fragmentation and removal link, and it is difficult to protect the whole process of tumor removal. The abdominal incision of single-port laparoscopic surgery is small, and since multiple instruments need to pass through the single hole to operate in the abdominal cavity, the instruments in the abdominal incision occupy space, which is not conducive to operation.

[0024] Holding the handle portion (34) of the support tube (3), the operating rod (2232) is passed through the channel (512) of the porous cover (5), the anti-drop hook (41) of the pulling wire (4) is hooked on the bolt hole (152) of the inner sheath (15) of the central rod, and the anti-drop ball (44) is pulled to tighten the pulling wire (4), so that the stop rail (151) of the inner sheath tube body of the central rod is matched with the stop rail groove (211) in the push tube (21) of the outer sheath (2), and the stop rail (151) of the inner sheath (15) of the central rod can slide along the stop rail groove (211) in the push tube (213) of the outer sheath (2); the stop rail (151) of the inner sheath tube body of the central rod is matched with the stop rail groove (311) in the sheath tube portion (31) of the support tube (3), and the end of the stop rail groove (311) of the sheath tube portion (31) of the support tube (3) limits the support tube (3) from sliding forward.

[0025] The protective bag (1), the elastic ring (13), the central rod inner core (14), and the central rod inner sheath (15) are assembled into a protective bag ring body (12345).

[0026] The single-port surgical incision (6) is placed in an incision protective cover (52), and the protective bag ring (12345) is placed into the abdominal cavity through the incision protective cover (52) under direct vision. The incision protective cover (52) is connected to the porous cover (5) and inflated to establish pneumoperitoneum. The joystick (2232) is held externally, and an endoscope and other instruments are inserted through the channel to assist. The elastic ring (13) is manipulated to insert the ovarian tumor (8) into the abdominal cavity, and the support tube (3) is pulled outward outside the abdominal cavity. The plate (22) of the outer sheath (2) is pushed inward, so that the push tube (21) of the outer sheath (2) slides over the inner sheath (15) of the central rod and contracts the elastic ring (13), and the protective bag opening (121) is pushed to tighten the pedicle of the ovarian tumor.

[0027] The gas in the abdominal cavity is evacuated, the porous cover (5) is separated from the incision protection sleeve (52), and the porous cover (5) is further pulled outward along the operating rod (2232).

[0028] The handle portion (34) of the support tube (3) is located outside the abdominal cavity, the pulling wire (4) is cut, and the thick support tube (3) is removed from the surgical incision.

[0029] The annular sealing ring (11) of the protective bag (1) in the abdominal cavity is pulled out of the body from the incision protective cover (52), and the porous cover (5) is connected to the annular sealing ring (11). The bag is inflated to establish a single-hole pneumoperitoneum operation space. The endoscope is placed into the protective bag (1) to observe and remove the ovarian tumor (8). If the tumor ruptures, the tumor contents are confined to the protective bag (1). The plate (22) of the outer sheath (2) is located between the incision protective cover (52) and the protective bag (1). The traction line (4) is pulled out of the abdominal cavity, and the plate (22) of the outer sheath (2) is pushed into the abdominal cavity, thereby locking the pedicle of the ovarian tumor.

[0030] After the ovarian tumor is removed, the pulling wire (4) is loosened, and the elastic ring (13) of the instrument in the protective bag (1) is expanded to release the clean and normal ovarian cortex after the tumor is removed from the protective bag (1) into the abdominal cavity. The pulling wire (4) in the support tube is pulled outward again to tighten. The pulling wire (4) after being pulled outward and tightened can be clamped in the longitudinal clamping channel (241) of the outer sheath (2), and is wound several times along the horizontal winding grooves (242) on both sides of the handrail (2223) and then clamped into the longitudinal clamping channel (241) for fixation.

[0031] Push the plate (22) of the outer sheath (2) downward into the abdominal cavity, close the opening of the elastic ring (13) with the push tube (21), and exhaust the gas in the protective bag (1). Hold the plate (22) of the outer sheath (2), and remove the protective bag ring (12345) and the tumor tissue (8) specimen in the bag through the single-hole incision (6).
