Problems solved by technology

[0005] When using the surgical channel for vaginal surgery, the surgical channel is usually inserted into the vaginal fornix in the patient's vagina. The vaginal fornix is ​​close to the bladder, uterus and rectum. When performing surgery on the bladder, uterus or rectum, the surgical Instruments extend from the surgical channel into the surgical site such as the bladder, uterus or rectum. Since the patient is often lying flat during the operation, the bladder and uterus will naturally sag, which is not conducive to separating human tissues from each other. For example, when operating on the uterus, When the patient lies flat on the operating table, the bladder is affected by gravity and moves closer to the area where the uterus is located, which will cause part of the bladder to occupy part of the operation area. The bladder may hinder the medical staff from performing the operation, which will increase the difficulty of the operation for the medical staff

Embodiment 1

[0041] Example 1: see figure 1 shown,

[0042] A tissue-shielding female channel provided in this embodiment includes a channel body 1, one end of the channel body 1 is an extending end 2, and the other end is a connecting end 3, and the connecting end 3 is used to connect an operation platform , the channel body 1 can extend into the patient's vagina from the extending end 2, and a blocking device 4 is provided on the channel body 1, and the blocking device 4 can extend and retract from the extending end 2 , when the blocking device 4 is extended, the blocking device 4 can block the tissue outside the surgical site.

[0043] The female channel includes a channel body 1, one end of the channel body 1 is a protruding end 2, and the other end is a protruding end 2. When the female channel is used, the vaginal body extends into the patient's vagina from the protruding end 2, and The protruding end 2 is placed at the uterine fornix, the operating platform is connected with the c...

Embodiment 2

[0044] Example 2: see Figure 1-11 shown,

[0045] On the basis of the technical solution of the first embodiment, further, the blocking device 4 includes a plurality of blocking sheets 5 surrounding the channel wall of the channel body 1 , and a plurality of the blocking sheets 5 can independently protrude from the extending end 2 and retracted, and the extended blocking sheet 5 can block the tissue outside the surgical site.

[0046] The blocking device 4 includes a plurality of blocking pieces 5 surrounding the channel wall of the channel body 1, and the plurality of blocking pieces 5 can be independently extended and retracted from the protruding end 2, so that the movement between the blocking pieces 5 on the channel body 1 is independent of each other When the female channel is used, the blocking sheet 5 at the tissue to be separated is extended from the channel body 1 to block the tissue outside the surgical site. For the part that does not need to be blocked, the bloc...

Embodiment 3

[0051] Example 3: see Figure 1-9 shown,

[0052] On the basis of the technical solution of the second embodiment, further, the channel body 1 is radially provided with a plurality of clamping grooves 6, the clamping grooves 6 are used to limit the movement trajectory of the blocking piece 5, and the blocking piece 5 can move along the axial direction of the channel body 1 .

[0053] The channel body 1 is radially provided with a number of card slots 6. The card slots 6 are matched with the blocking sheet 5. The card slots 6 are used to limit the movement track of the blocking sheet 5. The setting of the card slots 6 can restrict the blocking in the channel body 1. The movement of the sheet 5 and the shape of the blocking sheet 5 make the blocking sheet 5 closer to the channel wall of the passage body 1, which can further regulate the movement of the blocking sheet 5 on the passage body 1 and enhance the arrangement of the blocking sheet 5 on the passage body 1. stability. ...

Abstract

The invention relates to a tissue shielding type vaginal channel which comprises a channel body, one end of the channel body is a stretching-in end, the other end of the channel body is a connecting end, the connecting end is used for being connected with an operation platform, the channel body can stretch into the vagina of a patient from the stretching-in end, and a blocking device is arranged on the channel body. The blocking device can stretch out and retract from the stretching-in end, and when the blocking device stretches out, the blocking device can block tissue outside the surgical site. According to the scheme, the blocking device can stretch out and retract from the stretching-in end, when an operation is conducted on the bladder or the uterus or the rectum, the tissue needing to be conducted is located in the operation area corresponding to the channel body, the blocking device on the channel body stretches out, the tissue outside the operation site can be blocked by the blocking device, and therefore the operation is conducted on the bladder or the uterus or the rectum. When a vaginal surgery is carried out, the blocking device is used for blocking tissues outside a surgical site, a better surgical operation environment can be provided for medical staff, and the surgical quality is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tissue-shielding female channel. Background technique [0002] The traditional gynecological laparoscopic technique adopts pneumoperitoneum, which fully exposes the operative field, and has the advantages of clear images, less trauma to the patient's abdominal wall, and quick recovery, so it is widely used in gynecological surgery. However, this method still requires multiple small incisions in the abdominal wall, leaving scars. [0003] The traditional vaginal surgery adopts a natural channel approach, and extends into the surgical channel in the patient's body. The end of the surgical channel away from the protruding part is connected to an operating platform. The operating platform includes surgical instruments such as inflatable devices, laparoscopes and operating forceps. The surgical instrument is inserted into the depth of the patient's vagina along the surgical...
