Embodiment 1

[0020] As shown in Figures 1, 2, and 3, the cup-shaped sleeve is in the shape of a circular platform, with a large cup mouth and a small bottom. 60mm, the best is 55mm; the wall thickness of the cup-shaped sleeve is 5-6mm. Rod 1 passes through the center of the cup bottom of sleeve 2, the front end stretches out of the cup mouth, and the tail end is a handle portion 11 in the shape of a "T". The total length a of the rod 1 is 250-280mm, and the length e at the front side of the cup bottom is 65mm-75mm. In order to avoid damage to the vaginal wall when inserting the vagina, all corners are rounded excessively. For permanent use, the material can be stainless steel; for one-time use, the material can be non-toxic polypropylene.

Embodiment 2

[0022] As shown in Figure 4, it differs from Embodiment 1 in that the outer periphery of the rod 1 has threads 12, and the center of the bottom of the cup is a screw hole 21 that matches it. are fixed by threaded connections. During the operation, according to the size of the uterus, the rod-shaped object 1 is rotated to adjust the protruding length of its front end to the position of the fundus of the uterus, so that the uterus can be pushed up to play the role of lifting the uterus. This structure can keep the positioning spreader consistent with the longitudinal axis of the uterus and vagina without forming an angle, which is suitable for a larger uterus and is more conducive to identification and rotary cutting of the vaginal fornix. All the other parts are the same as in Example 1.

Embodiment 3

[0024] As shown in FIG. 5 , in this embodiment, the cup opening of the cup-shaped sleeve 2 is inclined, and the cup depth on one side is greater than that on the other side. The operator rotates the position when using it to fully expose the top of the fornix, look for the direction, and more accurately grasp the position of the rotary cut. All the other structures are with embodiment 2.

Abstract

A fornix vaginae locating retractor for the hysterectomy by use of peritoneoscope is composed of a cup shaped sleeve tube and a rod unit passing through the cup bottom of said cup-shaped sleeve tube and with a front end extended out of the cup mouth and a tail end as handle.

Description

technical field [0001] The invention relates to a medical instrument, which is a special surgical instrument for laparoscopic hysterectomy. Background technique [0002] Hysterectomy is an important means to treat various benign and malignant diseases of the uterus. Surgical methods mainly include abdominal, vaginal and laparoscopic three. Laparoscopic hysterectomy is increasingly chosen by surgeons and patients due to its advantages of minimal invasiveness, low postoperative morbidity, fast recovery, and short hospital stay. However, due to the influence of surgical instruments and the technical level of the surgeon, it is easy to cause damage to important organs such as the bladder, ureter, and rectum close to the uterus during the operation, so it is difficult to promote it in practice, especially in small and medium hospitals. Disaster. [0003] The Chinese Utility Model Patent No. 00235680.5 discloses a pulling fixator for laparoscopic hysterectomy, which includes a ...
