Description

A special enclosure device for revealing the operating field of minimally invasive surgery

technical field

The invention relates to the field of medical instruments, in particular to a special enclosure device for revealing a minimally invasive surgical field.

Background technique

Laparoscopic surgery is to use carbon dioxide gas to create artificial pneumoperitoneum as an observation and operation space, and use a trocar to establish a channel between the chest, abdomen, pelvis and the outside world through several small incisions of 0.5-1.0 cmd in the abdominal wall; insert a video system through the small incision. And the endoscope of the light source, the doctor completes the operation by observing the endoscope monitor and using surgical instruments to operate outside the body.

Sufficient exposure of the surgical field is one of the important factors to determine the success of laparoscopic surgery. However, because there are a large number of tissues and organs in the human chest, abdomen, and pelvis, most of the surgical sites are covered by the tissues and organs of the chest, abdomen, and pelvis, and must be retracted. Only the corresponding tissues and organs can reveal the operative field. Therefore, revealing the operative field is a difficult point in laparoscopic surgery.

Existing laparoscopic surgery mostly uses a fan-shaped retractor to expose the operative field, and the fan-shaped retractor mainly exposes the surgical field by pulling, and it is easy to strain various tissues in the body during the movement adjustment process, which is not conducive to the patient's postoperative recovery; The rib spreader is used to expose the surgical field. This method needs to spread the ribs, which can easily cause rib fractures. Long-term compression of the incision tissue can also easily lead to tissue necrosis, which will bring greater harm to the patient, which is not worth the loss.

Detailed ways

In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the present embodiment is described in detail as follows in conjunction with FIG. 1 , FIG. 2 and FIG. 3 .

The present invention provides a special enclosure device for revealing a minimally invasive surgical field. As shown in FIG. 1 , it includes an enclosure device body 1, and the enclosure device body 1 includes an enclosure front sheet 2, an enclosure rear sheet 3, The bottom sheet 21 and the left and right side sheets 22, the front sheet 2, the back sheet 3, the bottom sheet 21 and the side sheets 22 are seamlessly connected, the front sheet 2, the back sheet 3, the bottom sheet 21 and the side sheets 22 are connected seamlessly. After the seamless connection, a hollow accommodating cavity 5 is formed inside; the side piece 22 is inserted into the insertion tube 11, the outer wall of the insertion tube 11 is seamlessly connected with the side piece 22, and the top of the insertion tube 11 is connected with a water passage 12, and the insertion tube 11 is a moderately soft and hard material, and is closely connected with the side piece 22 to avoid the situation that the soft water pipe 12 is directly inserted into the side piece 22 and is prone to water leakage.

In practice, when the body 1 of the enclosure device is not filled with water, the doctor rolls the body of the enclosure device 1 into a cylindrical shape with a diameter of less than 1 cm outside the patient's body, as shown in Figure 3. The incision is sent into the patient's body; after the enclosure device body 1 enters the patient's body, it is unfolded with surgical forceps, the top of the water conduit 12 is connected to the water injection device, and the liquid enters the accommodating cavity 5 through the water conduit 12 and the placement tube 11, The body 1 of the enclosure device is stretched, as shown in Figure 1, the tissues and organs around the surgical field can be pushed open or topped open, preventing mobile tissues and organs from sliding into the surgical field and affecting the surgical operation; after the operation, the top of the water pipe 12 is connected to a negative pressure Suction device, after the negative pressure suction device is turned on, the liquid in the accommodating cavity 5 is taken away, and then the deflated enclosure device body 1 is rolled into a cylindrical shape with a diameter of less than 1 cm with surgical forceps, and is removed from the patient's body through the minimally invasive incision. .

Further, the enclosure front sheet 2 and the enclosure rear sheet 3 are trapezoids with smooth edges, and the left and right side sheets 22 are triangles without edges and corners; the edges of the entire enclosure device are smooth without edges and corners to avoid scratching the internal tissue of the patient's body; The trapezoidal structure of the enclosure device body 1 is relatively stable, and the bottom sheet 21 is a rectangle with rounded corners and has a certain width, which can support the enclosure device body 1 in a water-filled state to achieve an ideal enclosure effect.

Further, as shown in FIG. 1 , the enclosure device body 1 also includes a horizontally arranged deformation strip 4, the deformation strip 4 is a rectangle with an arc-shaped edge, and the deformation strip 4 has at least one piece, and the preferred deformation strip has 2 pieces. Arranged laterally from top to bottom on the surface of the front panel 2 and/or the back panel 3, the deformation strips 4 are horizontally arranged on the surface of the front panel 2 and/or the back panel 3, any section can be Deformation, the deformable range is large; place the enclosure device body 1 near the surgical field, and use the surgical forceps to pinch the position where you want the deformation strip to be deformed as needed to meet the deformation requirements. The hardness of the deformation strip is greater than that of the enclosure front sheet 2 and the enclosure back piece 3, as shown in Figure 2, so the corresponding position of the enclosure device body 1 will be bent, revealing the surgical field, and at the same time, it can also drain and open the surrounding tissues and organs, which plays a very good role. The enclosure function is helpful for the successful completion of the operation.

Further, the deformation bar 4 is an aluminum sheet or a soft steel wire, which has good ductility and variability, and can easily bend the body 1 of the enclosure device filled with water, which is conducive to fully revealing the surgical field.

Further, as shown in FIG. 1 , the surfaces of the multiple deformable strips 4 are covered with a protective film 41, and the body 1 of the enclosure device is moved into the body. The surface of the deformable strip 4 can deform any section of the deformable strip 4 while protecting the patient's tissues and organs.

Further, the bottom sheet 21 is made of frosted material, and the tissue fluid and tissues and organs in the patient are relatively slippery. The bottom sheet 21 is placed in the patient's body, and the frosted material can play an anti-slip effect to ensure the stability of the enclosure device body 1 during the operation.

Further, as shown in FIG. 1 and FIG. 2 , a liquid stop clip 121 is provided on the part of the water conduit 12 exposed outside the patient's body. During the operation, the liquid stop clip 121 is clamped on the water pipe 12 to ensure that the enclosure device body 1 is always in a state of water filling, and the liquid in the accommodating cavity 5 will not flow out; after the operation, the liquid stop clip 121 is opened, and the negative pressure The suction device is connected to the water pipe 12 to suck away the liquid in the accommodating cavity 5, and the liquid stop clip 121 is arranged on the part of the water pipe 12 exposed outside the patient's body, which is convenient for the doctor to operate.

Further, the enclosure device body 1 is made of medical silicone rubber material, with moderate hardness and softness, and the enclosure device body 1 will not cause damage to the patient's skin when taken in and out of the patient's body.

The present invention has been described by the above-mentioned related embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention belong to the scope of patent protection of the present invention.
