Description

Technical Field

[0001] The utility model relates to the technical field of medical surgical equipment, and more specifically, to an anorectal retractor and fixator system. Background Art

[0002] The anorectal department is a medical department that specializes in the research and treatment of diseases of the terminal digestive organs, covering a variety of diseases including lower rectal tumors, mixed hemorrhoids, internal hemorrhoids, external hemorrhoids, anal fissures, anal fistulas, constipation, perianal abscesses, anal strictures, anal papilla hypertrophy, and perianal eczema. During the diagnosis and treatment of these diseases, especially during surgical treatment, accurate lesion localization and effective surgical operations are crucial. Due to the special anatomical structure of the rectum and anus regions, obtaining and maintaining the surgical field of view has become a key factor in the success of the surgery.

[0003] In the prior art during transanal surgeries, a retractor is usually used to expand the anus to obtain a sufficient surgical field of view. These retractors are generally made of metal and sometimes come with a built-in light source to solve the problem of insufficient light in the surgical area during the operation. However, traditional metal retractors have exposed multiple problems in practical applications. First, when the metal retractor expands the anus, the exposure effect is not stable enough, often resulting in a poor surgical field of view. Second, although the metal retractor with a built-in light source can partially solve the lighting problem, its structural design reduces the effective range of the surgical space when expanding the anus, causing inconvenience to the doctor's operation. In addition, during the operation, the heads and shoulders of the surgeon and the assistant often block the shadowless lamp, resulting in insufficient light in the surgical area, which affects the doctor's operation judgment and accuracy.

[0004] For existing disc-shaped or ring-shaped retractors and fixators, although there is a certain improvement in the exposure effect compared to metal retractors, the problem of easy occlusion of the light in the surgical area has not been completely solved. The phenomenon of the surgeon and the assistant blocking the surgical light source still exists during the operation, resulting in uneven light in the surgical area, thus affecting the accuracy and effect of the surgery. In addition, these retractors and fixators also have problems such as unstable exposure effect and easy displacement during the operation, further increasing the complexity of the surgery and the doctor's workload.

[0005] In summary, the conventional techniques still have many deficiencies in solving the exposure of the surgical field of view and light illumination in anorectal surgeries. Although metal retractors and disc-shaped and ring-shaped retractors and fixators each have certain advantages, they have not completely solved the problems of light occlusion in the surgical area and the stability of the exposure of the field of view during the operation. These deficiencies not only increase the difficulty of the surgery and the doctor's workload, but may also have a negative impact on the success rate of the surgery and the patient's recovery effect. Therefore, it is necessary to further improve and innovate on the basis of the existing technology to provide a more stable and effective surgical field of view and sufficient light in the surgical area, and to improve the overall effect of anorectal surgeries.

[0055] Reference Figure 1 , in an embodiment of this application, an anorectal retractor fixation system 100 is provided, including:

[0056] A stent device 1 and an illuminating retractor device 2;

[0057] The stent device 1 can be erected on the peripheral area of the anus 200;

[0058] The illuminating retractor device 2 is provided with a retractor structure 21; one end of the illuminating retractor device 2 can hook the anus 200 through the retractor structure 21 and illuminate the surgical field inside the anus 200 based on the retractor structure 21, and the other end can be detachably connected to the stent device 1.

[0059] As described above, the anorectal retractor fixation system 100 realizes the organic combination of multiple functions through structural design and has significant technical advantages. This system mainly includes a stent device 1 and an illuminating retractor device 2.

[0060] As described above, the stent device 1 can be installed in the peripheral area of the anus 200 to provide stable fixed support. This design ensures a stable retraction effect during the operation and is not easily displaced or angled due to external factors, thus guaranteeing the continuous opening and clarity of the surgical field of view.

[0061] As described above, the peripheral area of the anus 200 refers to the buttock area outside the anus 200.

[0062] The shape of the stent device 1 can be rectangular, circular, arc-shaped, or can match the shape of the buttocks to facilitate the fixation effect. For example, it can include but is not limited to the following shapes or structures:

[0064] Ring-shaped stent: The ring-shaped structure can be evenly distributed in the peripheral area of the anus 200, providing all-round support and fixation effects.

[0065] Triangular stent: The triangular structure has high stability and achieves stable fixation through three support points, which is suitable for surgeries requiring high stability.

[0066] Frame-type stent: The frame-type structure is usually rectangular or square and forms a stable frame through multiple support points and connecting rods, which can adapt to different surgical needs.

[0067] Adjustable stent: This stent device 1 usually has adjustable arms and support points and can adjust the shape and size according to the surgical needs to provide the best fixation effect.

[0068] Folding stent: The folding design is convenient for carrying and storage and can be unfolded to form a stable support structure during use, which is suitable for mobile surgeries or emergency use.

[0069] Modular stent: The modular design allows adding or removing support modules according to surgical needs to provide a flexible support structure.

[0070] Support leg structure: This structure includes multiple support legs and can form a stable support platform by adjusting the position and angle of the support legs.

[0071] Clamping-type stent: The clamping-type structure usually has multiple clamps and can be clamped at different positions on the periphery of the anus 200 to provide stable support through multi-point fixation.

[0072] Suspension-type stent: The suspension design fixes the stent above the peripheral area of the anus 200 through a suspension device, reducing contact with the skin and providing an unobstructed operating space.

[0073] The designs of these shapes and structures can be selected and adjusted according to surgical requirements, the patient's physical conditions, and the operating environment to provide the best fixation effect and surgical field of view.

[0074] For the fixation of the stent device 1 to the buttocks mentioned above, it can be fixed through other structures. For example, it can include but is not limited to:

[0075] Clamping structure: An adjustable fixture is used and fixed on the skin or soft tissue around the anus 200. The clamping structure usually has an anti-slip gasket to avoid sliding and increase stability.

[0076] Suction cup structure: A medical-grade suction cup is used and fixed on the skin surface around the anus 200. The suction cup structure relies on the principle of vacuum adsorption to provide a stable fixation effect, and it is convenient for installation and disassembly.

[0077] Band-like fixation structure: The stent device 1 is fixed around the anus 200 through a medical elastic band or strap. The strap can adjust the tightness to adapt to the body types of different patients and surgical requirements.

[0078] Embedded structure: An embedded design is adopted, and the stent part is embedded into the subcutaneous tissue around the anus 200. This structure provides extremely high stability, but special surgical preparations and fixation techniques are required.

[0079] Adhesive structure: A medical adhesive is used to fix the stent device 1 on the skin around the anus 200. The adhesive structure is convenient for quick fixation and removal and is suitable for short-term surgeries.

[0080] Support leg structure: Multiple support legs are designed, and the stent device 1 is fixed around the anus 200 through multi-point support. The support legs can provide a stable fixation effect by adjusting the length and angle.

[0081] Snap ring structure: An elastic snap ring is used and sleeved on a specific position around the anus 200, and fixation is achieved through elasticity and friction. This structure is simple and effective and is suitable for various surgical scenarios.

[0082] Each fixation method or structure has its advantages and disadvantages. The selection of an appropriate fixation method should be comprehensively considered according to specific surgical requirements, the patient's physical condition, and the convenience of operation, etc.

[0083] As described above, the lighting retractor device 2 may include a retractor structure 21. One end of this structure can hook the anus 200 to achieve a reliable retraction effect. At the same time, the retractor structure 21 itself can integrate a lighting function, or can be illuminated by an additional lighting structure 23, so as to directly achieve the lighting effect within the surgical field. This direct lighting design effectively solves the problem of insufficient light during the operation and avoids the phenomenon of insufficient light caused by the surgeon and assistant blocking the shadowless lamp with their heads and shoulders.

[0084] As described above, the other end of the lighting retractor device 2 can be detachably connected to the bracket device 1. This design provides flexibility and convenience. The doctor can adjust the position and angle of the retractor device according to the actual surgical needs to ensure the best retraction effect and lighting angle. At the same time, this detachable design is convenient for surgical preparation, cleaning and disinfection, or can be discarded after being used as a disposable item, improving the efficiency and safety of the operation.

[0085] Generally speaking, the anorectal retraction and fixation system 100 provides stable retraction and sufficient lighting through the reasonable configuration of the bracket device 1 and the lighting retractor device 2, significantly improving the clarity of the surgical field and the accuracy of the operation.

[0089] As described above, the bracket device 1 includes a bracket body 11, a connection structure 12 and a power supply mechanism 13. The bracket body 11 provides the basic structure of the entire device, ensuring that the device can be stably erected in the peripheral area of the anus 200.

[0090] As described above, the connection structure 12 is arranged on the bracket body 11. The main function is to realize the detachable connection between the lighting retractor device 2 and the bracket device 1. Through this design, the lighting retractor device 2 can be flexibly installed and disassembled, facilitating surgical preparation and operation.

[0091] As described above, the power supply mechanism 13 provides power support for the lighting retractor device 2, enabling it to achieve the lighting function within the surgical field. This design solves the problem of insufficient light during the surgical process, provides a stable and sufficient light source 231, and helps doctors obtain a clearer view during the operation, improving the accuracy and safety of the operation.

[0092] As described above, the power supply mechanism 13 can be direct current or alternating current. For example, the power supply mechanism 13 is a lithium-ion battery or a sodium-ion battery.

[0093] As described above, the lighting retractor device 2 is electrically connected to the power supply mechanism 13 through the connection structure 12 to ensure stable power transmission to the lighting device. This design not only improves the stability of the lighting effect but also simplifies the operation process of the device, facilitating doctors to adjust and control during the operation.

[0094] In summary, by adding the stent body 11, the connection structure 12, and the power supply mechanism 13, the function of the anorectal retractor and fixation system 100 is further improved, making it more stable, convenient, and efficient during use. The detachable design of the connection structure 12 and the addition of the power supply mechanism 13 significantly enhance the practicality of the system, solve the problems of insufficient light and device instability during the operation, and improve the surgical effect and safety.

[0095] Furthermore, the stent body 11 is in the shape of a ring;

[0103] Furthermore, referring to Figure 2 , the connection structure 12 includes a connection body 121, and a connection slot 122 matching the cross-sectional shape of the lighting retractor device 2 is provided in the connection body 121;

[0104] In the connection slot 122, on the inner side wall of the connection body 121, an electrical connection point 123 corresponding to the lighting retractor device 2 is provided;

[0105] After the lighting retractor device 2 is installed in the connection slot 122, it can be electrically connected to the power supply mechanism 13 through the electrical connection point 123.

[0106] As described above, the connection structure 12 includes a connection body 121, and a connection slot 122 matching the cross-sectional shape of the lighting retractor device 2 is provided in the connection body 121.
