Problems solved by technology

However, this technology has the following disadvantages: the device needs to be vertically inserted into the abdominal cavity to a certain depth in the disturbed state before the support arm can be opened in an umbrella shape by pulling the rope, and the space in the abdominal cavity is limited. Blindly inserting the device and further opening it to the surroundings may cause damage to the intestinal tube; on the other hand, the device is moved from the distracted state to the extended state by the movement of the pull rope and prevents slippage. , due to minimally invasive reasons, the design of the device requires a small diameter and height, which results in a small displacement of the pulling rope sliding over the fulcrum during the process from the device being folded to the device being opened, and it is easy to be caused by excessive support of the abdominal wall. Due to the elasticity of the pulling rope material, the device cannot effectively maintain the ideal shape

Embodiment 1

[0040] Such as figure 2 As shown, a schematic diagram of the structure of a pneumoperitoneum-free laparoscopic abdominal wall suspension device, which also includes a hollow annular support ring 3, the support ring 3 is fitted on the inner wall of the ring sleeve, and the outer wall of the support ring is slightly smaller than the size of the ring sleeve The size of the inner wall is made into a cylindrical or conical shape according to the shape of the cutout protective cover 2 with the suspension function used, usually made of plastics or polyurethane or metal, and its hardness is greater than that of the cutout protection cover 2 with the suspension function.

[0041]When in use, the support ring is installed at the lower end of the inner wall of the ring sleeve 22 near the bottom of the lifting member. Because its hardness is greater than the hardness of the incision protective sleeve with suspension function, the tension of the ring sleeve is increased, thereby enhancing ...

Embodiment 2

[0043] Such as image 3 as shown, image 3 It is a schematic structural view of an embodiment of the pneumoperitoneum-free laparoscopic incision protection device of the present invention, which also includes a folded recess 24 at the central axis of the lifting member 23, and the thickness of the folded recess 24 is smaller than that of the pulling member. The thickness of the central area and the edge area; the outer wall of the ring sleeve 22 is provided with two concave along the line 25 parallel to each other and connected with the folding recess 24 of the lifting member, and the thickness of the concave along the line 25 is smaller than the thickness of the ring sleeve 22 .

[0044] When in use, since the folding recess at the central axis of the lifting part is thinner than the rest of the lifting part, the resistance decreases when the device is folded, making it easy to enter the incision during operation. The concave line connected to the folded recess, the thickne...

Embodiment 3

[0046] Such as Figure 4 , 5 as shown, Figure 4 , 5 It is a structural schematic diagram of another embodiment of the pneumoperitoneum-free laparoscopic incision protection device of the present invention. In this embodiment, a fixing plate is preferably provided on the upper part of the ring sleeve, and the fixing plate can be integrally formed with the incision protection sleeve. , the fixation plate remains outside the abdominal incision and can be combined with a fixation bracket (such as Figure 12 As shown), it plays the role of fixing the device and providing an upward suspension force so that the abdominal wall is suspended. The device can stretch the abdominal wall at the incision, and the lens and instruments used for surgery can enter the abdominal cavity through the central through hole of the incision protective sheath with the function of suspending. The support of the advanced incision protection sleeve device is stable and does not slide, providing a good ...

Abstract

A pneumoperitoneum-free peritoneoscope abdominal wall suspension device comprises a hollow incision protecting sleeve with a suspension function and a splint, wherein the incision protecting sleeve with the suspension function is formed by a lifting part, a ring sleeve and a fixing part in an integrated mode from bottom to top, the incision protecting sleeve and the splint are fixedly connected through the fixing part, the incision protecting sleeve with the suspension function is made of soft material, and the thickness of the lifting part is larger than that of the ring sleeve. Preferably, the device further comprises a hollow annular supporting ring installed on the inner wall of the ring sleeve in a matched mode, the shape of the supporting ring is consistent with that of the incision protecting sleeve, and the hardness of the supporting ring is larger than that of the incision protecting sleeve; more preferably, the thickness of the portion, close to the center area, of the lifting part of the incision protecting sleeve with the suspension function is smaller than that of the edge area of the lifting part; the abdominal wall below an operation incision can be supported by using the device, not only are unnecessary injuries to the abdominal wall avoided, but also an operation view is good, meanwhile, the pneumoperitoneum-free peritoneoscope abdominal wall suspension device is simple in structure and convenient to operate, pneumoperitoneum-free peritoneoscope surgery is completed by using conventional laparoscopic surgery instruments, and untoward effects caused by pneumoperitoneum are avoided.

Description

technical field [0001] The invention relates to the field of laparoscopic incision protection devices, in particular to an incision protection device for pneumoperitoneum-free laparoscopy. Background technique [0002] With the gradual improvement of medical technology, more and more diseases can achieve the best curative effect through laparoscopic minimally invasive surgery. Laparoscopic technique can produce CO 2 Artificial pneumoperitoneum provides the space required for surgical operations, but due to CO 2 Pneumoperitoneum can be secondary to complications such as hypercapnia, air embolism, and blood stasis, which limits the application of this technique in children with immature tissues and organs, pregnant women, and elderly patients with underlying diseases. Pneumoperitoneum-free laparoscopy is an important technology in the field of minimally invasive, using external mechanical tension to provide operation space for surgery, without relying on artificial pneumoper...
