Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to an arc-shaped protective sleeve. BACKGROUND

[0002] In pelvic fracture, the operation through the lower abdominal incision approach (such as the lateral incision of rectus abdominis or Stoppa approach, etc.) has multiple significant advantages. For example, the pelvic ring front side structure, including the pubic symphysis, pubic branch, part of iliac wing, sacroiliac joint and other key parts, can be exposed under direct vision through the lower abdominal incision approach. This exposure method helps doctors to observe the fracture more clearly, so as to perform more accurate reduction and fixation. At the same time, the minimally invasive surgical approach such as the lateral approach of rectus abdominis can expose the front and medial side of the hemi-pelvis and acetabulum under direct vision, so that the key structures such as internal and external iliac vessels, lumbosacral nerve, obturator vascular-nerve and "death crown" blood vessels are exposed in the field of view, providing convenience for surgical operation. And the smaller incision can also reduce the degree of injury and bleeding. However, the current operation through the lower abdominal incision approach needs to rely on traditional orthopedic retractors and other instruments for incision exposure, which is laborious and inefficient, and needs more assistants. The patent designs a special incision protective sleeve for pelvic fracture through the lower abdominal approach, which can effectively expose the incision, and the inner ring belt angle design can be closer to the periosteum, blocking the soft tissue around the periosteum, reducing the use of assistants, and providing stable and efficient incision retraction and soft tissue protection.

[0003] The current operation through the lower abdominal incision approach needs to rely on traditional orthopedic retractors and other instruments for incision exposure, which is laborious and inefficient, and needs more assistants. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing an arc-shaped protective sleeve, which can effectively expose the incision, and the inner ring belt angle design can be closer to the periosteum, blocking the soft tissue around the periosteum, without the need for too many assistants to provide stable and efficient incision retraction and soft tissue protection.

[0005] The utility model realizes the following technical scheme: an arc-shaped protective sleeve, which comprises an outer clasp ring, a channel and an inner ring arranged in sequence from top to bottom; wherein the outer clasp ring is connected to the upper edge of the channel, and the inner ring is connected to the lower edge of the channel.

[0006] The arrangement of the inner ring with the front high and the rear low makes the bottom of the channel be inclined, and the inner ring is divided into the left part and the right part based on the line connecting the high point and the low point, and both the left part and the right part are bent downward.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] 1. The beveled design at the bottom of the implantation ring, and the downward bending design of the left and right parts of the implantation ring, make the utility model more conform to the tissue morphology during the operation.

[0009] 2. Two schemes are derived according to different materials, and users can select appropriate products according to different scenes and needs.

[0010] 3. The product supported by medical silica gel can realize self-supporting due to the certain toughness of the material, so that a stable instrument channel can be formed after it is placed in the incision.

[0011] 4. The channel provided with the annular air bag can provide effective support for the incision opening and form a stable instrument channel, facilitate the operation, and reduce the operation time.

[0012] 5. The annular air bag additionally matched with the columnar air bag can further improve the strength of the membrane channel and ensure the stability of the instrument channel. BRIEF DESCRIPTION OF DRAWINGS

[0022] The utility model will be described in detail in combination with the drawings, but the protection content of the utility model is not limited to the following description:

[0023] For example, Figures 1 to 8As shown, an arc-shaped protective sleeve includes an outer retaining ring 11, a channel 12, and an insertion ring 13 arranged sequentially from top to bottom; wherein, the outer retaining ring 11 is connected to the upper edge of the channel 12, and the insertion ring 13 is connected to the lower edge of the channel 12.

[0024] The insertion ring 13 is arranged with a higher front and lower back, making the bottom of the channel 12 slanted. The insertion ring 13 is divided into a left insertion ring and a right insertion ring based on the line connecting the high point and the low point, and both the left and right insertion rings bend downwards. The arrangement of the insertion ring with a higher front and lower back makes the bottom of the channel slanted, and the insertion ring is divided into a left insertion ring and a right insertion ring based on the line connecting the high point and the low point, which better conforms to the tissue shape.

[0025] Based on the material of this utility model, the following two embodiments can be derived from this application;

[0026] Example 1:

[0027] The outer retaining ring 11, channel 12, and insertion ring 13 are all made of medical-grade silicone. Medical-grade silicone itself has a certain strength, and after insertion into the incision, it can automatically maintain its open state, ensuring the stability of the channel. It should be noted that medical-grade silicone protective sleeves are existing products. Except for the shape of the lower edge, which differs from traditional silicone protective sleeves, the structure and usage of other parts in this application are consistent with traditional silicone protective sleeves.

[0028] Example 2:

[0029] like Figure 1 , 2 As shown: Channel 12 is a thin-film channel made of thermoplastic elastomer. The insertion ring 13 is made of shape memory alloy. The shape memory alloy material of the insertion ring allows it to recover its original shape after being compressed and reinserted into the human body.

[0030] Furthermore, an annular air bladder 15 is provided around the outer wall of the membrane channel, and the annular air bladder 15 is connected to a ventilation device 14. Inflation provides support.

[0031] Furthermore, the outer wall of the membrane channel is provided with a plurality of columnar air bladders 16, which are interleaved and communicate with the annular air bladders 15. The additional columnar air bladders 16 further improve the support strength of the membrane channel.

[0032] The airbag structure of this invention can provide support for the incision opening and form a stable instrument channel, which facilitates surgical operation and reduces surgical time.

[0033] like Figure 6Further, the venting device 14 comprises a venting pipe 141 and a two-way valve 142, one end of the venting pipe 141 is connected with the two-way valve 142, and the other end of the venting pipe 141 is connected with the annular air bag 15. The structure of the venting pipe and the two-way valve are both conventional technologies, so no more detailed description is given.

[0034] In summary, the use method of the utility model is as follows: after the incision is cut, the insertion ring 13 is pressed to make the whole insertion ring 13 enter the human body through the incision, then air is injected into the annular air bag 15 through the two-way valve 142, and the air bag 15 forms a dilating force after being inflated. It should be noted that if a cylindrical air bag is arranged, since the cylindrical air bag and the annular air bag are communicated, air is injected into the annular air bag 15 at the same time, and air is also injected into the cylindrical air bag. The insertion ring 13 made of a memory alloy material restores deformation, so that the insertion ring with an angle design can be closer to the periosteum, and the instrument channel formed by the protective sleeve can support the operation to ensure that the operation has sufficient operation space.

[0035] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications within the spirit range of the utility model can be implemented. Therefore, it should be understood that the utility model is not limited in any sense except for the appended claims and their equivalents.
