Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples. The following examples are given for the purpose of illustration only and are not intended to be limiting.

As shown in fig. 1-4, a pelvic cavity double-leaf retractor for a laparoscope comprises an outer tube body 1, wherein a notch 9 is formed on the upper surface of the head end of the outer tube body 1; a fixed blade 4 is fixed on the outer tube body 1 at one side of the notch 9; a rotating shaft 5 is arranged in the outer tube body 1, a movable blade 3 is fixed at the head end of the rotating shaft 5, and a blade gap 11 is formed between the movable blade 3 and the fixed blade 4; a connecting part 10 is formed on the inner side of the bottom end of the movable blade 3, the connecting part 10 penetrates through the notch 9 of the outer tube body 1, one end of the connecting part is sleeved on the rotating shaft 5, and the other end of the connecting part is connected with the movable blade 3; the rear part of the rotating shaft 5 penetrates through the outer tube body 1, the tail end of the rotating shaft is connected with the handle 2, and a limiting piece 6 in a cone shape is fixed on the rotating shaft 5 between the handle 2 and the tail end of the outer tube body 1; the tail end of the outer pipe body 1 and the limiting piece 6 are sleeved with a fastening piece 7, the fastening piece 7 is sleeved on the inner wall of one side of the outer pipe body 1 to form an internal thread, and an external thread matched with the inner wall of the fastening piece 7 is formed on the outer wall of the tail end of the outer pipe body 1.

The included angle formed by the movable blade 3 and the fixed blade 4 is 0-180 degrees.

The included angle formed by the movable blade 3 and the fixed blade 4 is 0 degree, and the movable blade 3 and the fixed blade 4 are completely overlapped.

The handle 2 is provided with a plurality of anti-slip ribs 8.

The diameter of the bottom surface of the limiting part 6 close to one end of the handle 2 is larger than that of the bottom surface of the end far away from the handle 2.

The diameter of the through hole of the fastener 7 sleeved on one side of the limiting part 6 is smaller than the diameter of the bottom surface of the maximum bottom surface of the limiting part 6.

The movable blade 3 and the fixed blade 4 are plate-shaped.

The leaf gap 11 gradually increases from the trailing end to the leading end of the two leaves.

When the movable leaf 3 and the fixed leaf 4 are overlapped at an angle of 0 degree, the sum of the widths of the two leaves and the outer sleeve 1 is less than or equal to 1.5 cm; the width of the tail end of each leaf is less than or equal to 1.2cm, the width of the head end of each leaf is about 0.8cm, and the length of each leaf is 3 cm; the widest part of the leaf space 11 is 1.4 cm.

The utility model discloses a use method does:

in the case of radical prostate cancer, during the procedure, the operator detaches the seminal vesicles and appropriately detaches the denovilliers fascia between the prostate and rectum. At this point, it is necessary to continue to free the bilateral pedicles of the prostate and place the device through the Torcar with a 15-hole diameter.

Before getting into the pelvic cavity, movable leaf 3 and fixed leaf 4 are 0 jiaos of overlapping and set up, get into pelvic cavity back twist grip 2, movable leaf 3 rotates under the drive of rotation axis 5, make two leaf separation reach suitable angle after, the operator rotates fastener 7 with the hand, make fastener 7 remove to handle one side, because locating part 6 is the round platform shape, along with fastener 7's removal, fastener 7 fastens locating part 6, thereby play fixed rotation axis 5, and then the effect of fixed movable leaf 3. Then one of the leaves is inserted into the gap between the prostate and the rectum, the other leaf is propped against the side wall of the pelvic cavity, and the leaf gap 11 between the two leaves is clamped at the vascular pedicle of the prostate. Therefore, on one hand, the side wall planes of the rectum and the pelvic cavity are protected from being damaged, on the other hand, the neurovascular bundle on the side of the prostate is fully exposed, and the protection of the free suture of the blood vessel and the corresponding nerve and the urinary nerve of an operator is facilitated. The opposite sidewall plane was separated in the same way.
