Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laparoscopic surgery technology, specifically relating to an incision protection device that eliminates the need for pneumoperitoneum. Background Technology
[0002] Pneumoperitoneum is a key technique that creates an artificial air cavity by injecting gas (usually carbon dioxide or CO2) into the abdominal cavity, providing operating space and a clear surgical field for laparoscopic surgery. It is widely used in general surgery (cholecystectomy, appendectomy, gastrointestinal surgery, liver surgery, etc.), gynecology (hysterectomy, cystectomy, adnexal resection), and urology (radical prostatectomy, partial nephrectomy, adrenal tumor resection). However, pneumoperitoneum may cause intraoperative complications such as subcutaneous emphysema, pneumothorax, hypercapnia, and arrhythmia.
[0003] Wound protector / retractor is an instrument used during surgery to protect the incision, reduce tissue damage, lower the risk of infection, and improve the surgical field. It is commonly used in various laparoscopic surgeries.
[0004] To reduce complications associated with pneumoperitoneum, existing solutions typically employ a suspension method. This involves modifying the incision sheath by adding a device that can grasp the inner side of the abdominal cavity. By suspending the incision sheath, the abdominal wall is suspended, thus obtaining a good field of vision and sufficient operating space, achieving pneumoperitoneum-free operation. However, the devices added to the incision sheath are usually complex in structure, inconvenient to use, and prone to parts falling into the body, leading to increased surgical time.
[0005] Therefore, how to avoid the inconvenience of using protective sleeves for pneumoperitoneum incisions is a technical problem that urgently needs to be solved in this field.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0007] This disclosure provides at least one incision protection device that eliminates the need for pneumoperitoneum.
[0008] In a first aspect, embodiments of this disclosure provide an incision protection device for gas-free abdominal surgery, comprising: a support ring having a plurality of abdominal support pieces integrally disposed on its sidewall; the end of each abdominal support piece having a suspension hole; and the suspension hole being configured to allow the passage of a suspension wire for lifting the abdominal support piece.
[0009] In one alternative embodiment, the support plate array is disposed on the sidewall of the support ring, and the number of support plates is not less than three.
[0010] In one alternative embodiment, the support sheet is made of a flexible material.
[0011] In one alternative embodiment, the ratio of the root width to the end width of the support piece is 0.75-0.9.
[0012] In one alternative embodiment, the thickness of the support sheet gradually decreases from the root to the end.
[0013] In one alternative embodiment, a transition arc is provided at the apex corner of the end of the support piece.
[0014] In one alternative implementation, at least two suspension holes are provided to allow multiple suspension wires to be threaded through.
[0015] In one optional embodiment, a protective sleeve is provided on the top of the support ring; wherein, a flip ring is integrally provided on the top of the protective sleeve, and a mounting ring is provided on the bottom of the protective sleeve; the flip ring is made of flexible material and has an outwardly rolled edge towards the mounting ring side to form a clamping part with the mounting ring.
[0016] In one alternative embodiment, the top of the support ring is provided with a mounting groove; the mounting ring is welded into the mounting groove.
[0017] In one alternative embodiment, the protective sleeve is tapered at the waist.
[0018] The beneficial effects of this utility model are that the incision protection device for gasless abdominal surgery has several support plates integrally set on the side wall of the support ring. When the support ring is inserted, the support plates are directly placed inside the abdominal cavity, and then the end of the support plate is pulled to suspend the abdominal wall. Furthermore, when inserting the suspension suture, the suspension suture is first inserted into the abdominal cavity from the designated position and led out from the incision. After being inserted into the suspension hole, the support ring is then inserted, and the suspension suture is pulled directly. This simplifies the structure and reduces the difficulty of use, effectively shortening the operation time.

[0039] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0040] See Figures 1 to 4 This invention discloses a gasless incision protection device, comprising: a support ring 1, the sidewall of which is integrally provided with a plurality of abdominal support plates 11; the end of each abdominal support plate 11 is provided with a suspension hole 11a; the suspension hole 11a is configured to pass through a suspension suture for lifting the abdominal support plate 11; in short, this gasless incision protection device has a plurality of support plates 11 integrally provided on the sidewall of the support ring 1. When the support ring 1 is inserted, the support plate 11 is directly placed inside the abdominal cavity, and then the end of the support plate 11 is lifted to suspend the abdominal wall; furthermore, when passing through the suspension suture, the suspension suture is first inserted into the abdominal cavity from a designated position and led out from the incision, passed through the suspension hole 11a, and then the support ring 1 is inserted, and the suspension suture is directly lifted, which simplifies the structure and reduces the difficulty of use, effectively shortening the operation time.
[0041] In some embodiments, the support plates 11 are arrayed on the side wall of the support ring 1, and the number of support plates 11 is not less than 3; in short, in order to ensure stable support for the abdominal cavity, the support plates 11 are dispersed and arrayed on the side wall of the support ring 1 to ensure multi-point support within the abdominal wall and achieve suspension of the abdominal wall.
[0042] In some embodiments, the support sheet 11 is made of a flexible material; in short, the support sheet 11 is made of a flexible material, which allows the support sheet 11 to be rolled or folded for ease of placement.
[0043] In some embodiments, the ratio of the root width to the end width of the support piece 11 is 0.75-0.9; in short, see [link to relevant documentation]. Figure 3 The support plate 11 has a base width of L1 and an end width of L2. Since the suspension wire is threaded through the end of the support plate 11, in order to ensure that the support plate 11 does not bend too much when suspending the abdominal cavity, resulting in poor opening of the abdominal cavity, the width of the end of the support plate 11 is widened to improve the bending resistance of the support plate 11 and thus improve the support effect on the abdominal cavity. Furthermore, the increased width at the base of the support plate 11 can increase the contact area with the abdominal wall, thereby improving the support effect on the abdominal wall.
[0044] In some embodiments, the thickness of the support piece 11 gradually decreases from the root to the end; in short, the thickness of the support piece 11 is increased at the root to prevent the support piece 11 from cracking or breaking and to improve the safety of use.
[0045] In some embodiments, a transition arc 11b is provided at the apex corner of the end of the support piece 11; in short, to avoid scratching tissue at the apex corner of the support piece 11, a transition arc 11b is provided at its apex corner; furthermore, the edges of the support piece 11 are also provided with rounded corners to further improve the safety of use.
[0046] In some embodiments, at least two suspension holes 11a are provided to thread multiple suspension wires; in short, at least two suspension holes 11a are provided to thread multiple strands of rope, thereby improving ease of use.
[0047] In some embodiments, a protective sleeve 12 is provided on the top of the support ring 1; wherein, a flip ring 12a is integrally provided on the top of the protective sleeve 12, and an mounting ring 12b is provided on the bottom of the protective sleeve 12; the flip ring 12a is made of flexible material and is flipped and rolled outward toward the mounting ring 12b to form a clamping part with the mounting ring 12b; in short, the protective sleeve 12 is a circular film, and by flipping the flip ring 12a outward, the protective sleeve 12 is rolled up, and finally the flip ring 12a flips to fit the skin on the outside of the incision, while the mounting ring 12b is integrally located inside the body with the support ring 1. The flip ring 12a and the mounting ring 12b complete the covering of the skin on the inside and outside of the incision, so that the protective sleeve 12 fits the incision and completes the protection of the incision.
[0048] In some embodiments, the top of the support ring 1 is provided with a mounting groove 13; the mounting ring 12b is welded into the mounting groove 13; in short, the mounting ring 12b is integrally disposed in the mounting groove 13 by ultrasonic welding.
[0049] In some embodiments, the protective sleeve 12 is designed to be tapered at the waist; in short, the tapered design of the protective sleeve 12 facilitates the flipping of the flip ring 12a and improves the convenience of use.
[0050] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0051] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0052] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0053] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0054] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
