Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a breast surgery incision opener. Background Technology

[0002] In breast surgery, opening the surgical incision is a crucial step. Traditional methods often rely on surgical forceps or manual traction by an assistant. This approach is not only cumbersome but also makes it difficult to precisely control the size and shape of the incision, potentially obstructing the surgical field and affecting the accuracy and efficiency of the procedure. Furthermore, prolonged traction can cause unnecessary damage and discomfort to the patient's skin.

[0003] With the continuous advancement of medical technology, various retractors for breast surgery incisions have gradually emerged on the market, improving upon the shortcomings of traditional methods to some extent. However, existing retractors still have some limitations in their design, such as insufficient stability, poor adaptability, and inconvenience in operation. For example, some retractors are prone to movement due to external forces when opening the incision, affecting the stability of the surgery; some retractors cannot be flexibly adjusted according to the size and shape of the surgical incision, limiting their applicability; and some retractors require multiple components to work together during operation, increasing the complexity and difficulty of the procedure.

[0004] Therefore, it is necessary to design a more stable, flexible, and easy-to-operate breast surgery incision retractor to meet the needs of clinical surgery. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a breast surgery incision retractor. By optimizing the structural design of the retractor, the accuracy, stability, and comfort of the surgery are improved, and the patient's pain and discomfort are reduced.

[0006] To achieve the above objectives, the utility model adopts the following technical solution: a breast surgery incision retractor, comprising a base plate with a surgical opening in the middle, a pad frame at the bottom edge of the base plate, two rotatable retractor hooks symmetrically arranged on the inner side of the base plate, a flip-up lever arm at the top of the retractor hook, and a stabilizing frame on both sides of the two retractor hooks.

[0007] Through the above-mentioned technical means, the surgical opening in the middle of the substrate facilitates surgical operation and reduces obstruction of the surgical field of vision. The rotatable opening hook and the flip-up lever arm design make it easy for doctors to adjust the size and shape of the incision according to the needs of the surgery, improving the flexibility and accuracy of the surgery. The setting of the stabilizing frame enhances the overall stability of the retractor and prevents the surgical effect from being affected by accidental movement during the operation.

[0008] Furthermore, at both ends of the inner walls on both sides of the surgical incision, rotation grooves adapted to the撑开hooks are provided, and the inner walls on both sides of the surgical incision are arc-shaped surfaces. The design of the rotation grooves on the inner walls on both sides of the surgical incision enables the撑开hooks to rotate smoothly, and the arc-shaped surface design better adapts to the human body curve, reducing the pressure on the patient's skin.

[0009] Furthermore, the cross-section end of the cushion frame is a trapezoidal frame. Such a design increases the contact area between the cushion frame and the patient's skin, improves stability and comfort, and also helps to disperse pressure and reduce damage to the patient's skin.

[0010] Furthermore, a mounting notch is provided in the middle of the upper end of the撑开hook, and the length of the mounting notch is greater than the inner spacing between the two rotation grooves on the same side. The design of the mounting notch at the upper end of the撑开hook enables the撑开hook to more flexibly adapt to the width of the surgical incision during installation, while ensuring the stability of the撑开hook during the rotation process.

[0011] Furthermore, the撑开hook is rotationally mounted on the inner walls on the opposite sides of the two rotation grooves on the same side through a shaft rod. The撑开hook is rotationally mounted in the rotation groove through a shaft rod, ensuring the smooth rotation and stability of the撑开hook.

[0012] Furthermore, the surface of the lower half of the撑开hook is wrapped with a silicone protective sleeve, reducing the direct contact between the撑开hook and the patient's skin, increasing the comfort of the patient, and also reducing the risk of skin damage.

[0013] Furthermore, on the opposite sides of the two force arms, each is hinged to the top end of the撑开hook on the same side through a hinge. The force arm is connected to the top end of the撑开hook through a hinge, making the flipping operation of the force arm more flexible and convenient. The doctor can easily adjust the angle and position of the force arm according to needs.

[0014] Furthermore, locking holes adapted to the stabilizing frame are provided on both sides of the two撑开hooks. The matching design of the locking holes on both sides of the撑开hook and the stabilizing frame enables the doctor to lock the position of the撑开hook according to needs during the operation, preventing its accidental movement, thereby ensuring the stability and safety of the operation.

[0015] Furthermore, the stabilizing frame is a "匚"-shaped rod, and the stabilizing frames are paired in twos and a plurality of pairs are provided. The lengths of each pair of stabilizing frames are different. This design enables the stabilizing frame to be flexibly selected and adjusted according to the size and shape of the surgical incision, enhancing the adaptability and stability of the retractor. At the same time, the setting of multiple pairs of stabilizing frames also improves the overall strength and support effect of the retractor.

[0016] Furthermore, a gel patch is provided at the bottom of the pad frame. After the retractor opens the incision, the gel patch is applied to the normal skin outside the incision, which can increase the fit with the patient's skin, reduce slippage and discomfort, thereby enhancing the stability of the retractor and providing a certain degree of protection.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Optimized surgical field of view: The surgical opening in the middle of the substrate provides doctors with a clear surgical field of view, reduces the obstruction of the surgical area by instruments and other components, and helps doctors to perform surgical operations more accurately.

[0019] 2. Improved patient comfort: The gel patch at the bottom of the pad fits closely to the patient's skin, reducing friction and discomfort. The softness of the gel also provides a certain level of comfort. In addition, the silicone protective sleeve covering the lower half of the hook further reduces irritation to the patient's skin, minimizing potential pain or discomfort during the procedure.

[0020] 3. Flexibility and stability of surgical operation: The retractor hook is rotatably mounted in a rotating slot via a shaft, allowing the surgeon to adjust its angle and position according to surgical needs, increasing surgical flexibility. Simultaneously, the design of the stabilizing frame and locking hole ensures the retractor hook remains stable during surgery, preventing accidental movement and guaranteeing surgical stability and safety. Furthermore, the lever arm is hinged to the top of the retractor hook, and its flip-up design allows the surgeon to adjust the angle of the lever arm as needed, making it easier to control the opening and closing of the retractor hook and improving the convenience of surgical operation.

[0021] 4. Rationality of structural design: The trapezoidal frame design of the pad increases the contact area with the patient's skin, improves stability, and also helps to distribute pressure and reduce the pressure on the patient's skin; in addition, the installation notch at the top of the opening hook and the rotating grooves on both sides of the surgical opening make the installation and rotation of the opening hook smoother and reduce the difficulty of operation.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0030] like Figure 1 As shown in Figure 5, the specific scheme of Embodiment 1 is as follows: A breast surgical incision retractor includes a base plate 1 with a surgical opening 11 in the middle, a pad frame 2 at the bottom edge of the base plate 1, two rotatable retracting hooks 4 symmetrically arranged on the inner side of the base plate 1, a flip-up lever arm 6 at the top of the retracting hook 4, and a stabilizing frame 7 on both sides of the two retracting hooks 4.

[0031] Under normal circumstances, human skin is elastic. When the retractor 4 opens the incision, the skin at the incision will automatically retract, thereby applying an inward squeezing force to the retractor 4 and fixing the entire retractor in place.

[0032] Example 2: Based on Example 1, a gel patch 3 is provided at the bottom of the pad frame 2. After the opening is opened by the opening hook 4, the gel patch 3 at the bottom of the pad frame 2 can be applied to the normal skin outside the opening, thereby making the entire opening device more stable.

[0033] like Figure 3 , Figure 4As shown, the surgical opening 11 in the middle of the substrate 1 facilitates surgical operation and reduces obstruction of the surgical field. The gel patch 3 at the bottom of the pad frame 2 can increase the fit with the patient's skin, reduce slippage and discomfort, and provide a certain degree of protection. The rotatable retractor hook 4 and the flip-up lever arm 6 design make it easy for doctors to adjust the size and shape of the incision according to the needs of the surgery, improving the flexibility and precision of the surgery. The setting of the stabilizing frame 7 enhances the overall stability of the retractor and prevents the surgical effect from being affected by accidental movement during the operation.

[0034] In this embodiment, rotating grooves adapted to the spreading hook 4 are provided at both ends of the inner walls on both sides of the surgical opening 11. Simultaneously, an installation notch 41 is provided in the middle of the upper end of the spreading hook 4, the length of which is greater than the inner distance between the two rotating grooves on the same side. The rotating groove design on the inner walls on both sides of the surgical opening 11 allows the spreading hook 4 to rotate smoothly, and the installation notch 41 at the upper end of the spreading hook 4 allows it to adapt more flexibly to the width of the surgical opening 11 during installation, while ensuring the stability of the spreading hook 4 during rotation.

[0035] The spreading hook 4 is rotatably mounted on the inner wall of two opposing rotating slots on the same side via a shaft. This rotatable mounting of the spreading hook 4 within the rotating slots ensures smooth and stable rotation.

[0036] The inner walls of both sides of the surgical opening 11 are curved, and all edges of the surgical opening 11 are rounded. The curved design better conforms to the curves of the human body and reduces pressure on the patient's skin.

[0037] like Figure 1-3 As shown, the end of the cross-section of the pad frame 2 is a trapezoidal frame. This design increases the contact area between the pad frame 2 and the patient's skin, improving stability and comfort, while also helping to distribute pressure and reduce damage to the patient's skin.

[0038] like Figure 1 As shown, a silicone protective sleeve 5 is wrapped around the lower half of the spreader hook 4, which reduces the direct contact between the spreader hook 4 and the patient's skin, increases the patient's comfort, and also reduces the risk of skin damage.

[0039] In addition, in this application, both the silicone protective sleeve 5 and the gel patch 3 that come into contact with the skin are made of medical grade. This choice not only improves the patient's comfort but also has a certain degree of biocompatibility and safety, reducing possible complications during the operation.

[0040] The two lever arms 6 are hinged to the top of the opening hook 4 on the same side on opposite sides. The lever arms 6 are connected to the top of the opening hook 4 by hinges, which makes the flipping operation of the lever arms 6 more flexible and convenient. Doctors can easily adjust the angle and position of the lever arms 6 as needed.

[0041] On both sides of the two spreading hooks 4, locking holes 42 adapted to the stabilizing frame 7 are provided. The adaptation design of the locking holes 42 on both sides of the spreading hooks 4 and the stabilizing frame 7 enables the doctor to lock the position of the spreading hooks 4 as needed during the operation, preventing their accidental movement, thereby ensuring the stability and safety of the operation.

[0042] The stabilizing frame 7 is a "C"-shaped rod. The stabilizing frames 7 are paired in twos and a plurality of pairs are provided. The lengths of each pair of stabilizing frames 7 are different. This design enables the stabilizing frame 7 to be flexibly selected and adjusted according to the size and shape of the surgical incision, enhancing the adaptability and stability of the spreader. At the same time, the setting of multiple pairs of stabilizing frames 7 also improves the overall strength and support effect of the spreader.

[0043] The working principle of the above embodiment is as follows: When in use, first insert a part of the silicone protective sleeve 5 into the incision, then apply the gel patch 3 on the skin outside the incision, then relatively flip the two force arms 6 to make the two force arms 6 stand up, and then continuously apply relative pressure, so that the two spreading hooks 4 gradually open the incision. After reaching the predetermined opening angle, the doctor selects a stabilizing frame 7 with a corresponding length and inserts the stabilizing frame 7 into the locking hole 42 on the side of the spreading hook 4 to fix the size of the incision.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
