Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an embedded two-stage plastic scissors with integrated design and shearing functions for labia minora arc excision surgery using the edge method. Background Art
[0002] It is generally believed that the modern aesthetic concept of labia minora is: bilateral symmetry, light pink color, not protruding from the labia majora, and shaped like a "willow leaf" or "clamshell". Various congenital or acquired factors can cause hypertrophy of the labia minora, pigmentation of the edges, or asymmetry, which brings physical and psychological burdens to some women.
[0003] Labiaplasty is a superficial cosmetic surgery that can solve the above problems. The mainstream surgical methods include: edge excision, wedge excision, combined excision, etc. Among them, edge excision is the most widely used in clinical practice.
[0004] However, in order to achieve the above ideal effect, the line design before surgical cutting often takes up a lot of time and energy. Due to the natural characteristics of the labia minora being soft and easily deformed by pulling, it is difficult to achieve left-right symmetry under different tension conditions. In addition, the current surgical process requires the injection of fluid into the labia minora tissue gap after the line design to achieve local anesthesia and vasoconstriction. At this time, the morphological changes of tissue edema make it more difficult to achieve "what you see is what you get" during cutting. In short, the two steps of design and cutting are carried out asynchronously, making it difficult to achieve the perfect "left-right mirror effect".
[0005] At present, there is no corresponding surgical auxiliary device in clinical practice. It is necessary to devote energy to explore it in order to improve surgical results and reduce surgical difficulty. Summary of the invention
[0006] (1) Technical problems solved:
[0007] In view of this, the present invention provides an embedded two-stage plastic scissors for auxiliary edge method labia minora excision surgery. The plastic scissors can be used to separate and fix the two labia minora at the same time without tension. The design clamp function unit provided by light clamping can achieve fine adjustment of the excision part of the labia minora edge according to the golden ratio. Then, the excision scissor function unit provided by heavy clamping can achieve synchronous excision of redundant tissue. Compared with the current clinical reliance on assistants to fix the labia minora by hand, it can ensure better design stability in a natural and non-traction state, and can also ensure the golden ratio and mirror symmetry effect of the retained parts of the labia minora on both sides, while saving manpower and time costs.
[0008] (2) Technical solution:
[0009] In order to achieve the above-mentioned purpose, the two-stage plastic scissors for edge method labia minora excision surgery provided by the present invention include: a clamp functional unit and an excision shear functional unit, both of which are coaxially arranged in an upper and lower three-dimensional manner, and the blade parts are all bent upward at an angle of 60° to achieve unobstructed straight view, and rely on the embedded design of the handle part to achieve a two-stage control effect of light clamping design and heavy clamping cutting by sharing a single handle.
[0010] The appearance of the functional unit of the designed pliers is "three-leaf scissors-like", including five components: two pages of designed pliers on the left and right, a middle partition and two springs. ① The designed pliers are composed of three parts: the head, the joint and the handle. The head pliers are designed in a "1 / 2 willow leaf" style, with a straight bottom edge and hollow scales on it. The total length is 5cm (according to "Female Genital Plastic Surgery", the average length of the labia minora is 3 to 5cm), the upper edge is an arc edge, and the arc edge is a non-parabolic design. The highest point is 1cm wide from the bottom edge (according to the "Chinese Expert Consensus on Plastic Surgery for Hyperplasia and Hypertrophy of the Labia Minor 2022 Edition", the width of the labia minora should be retained at 1.0±0.2cm), and the highest point is located at the straight The golden ratio (0.618:1) of the side projection is divided (according to the "Chinese Expert Consensus on Plastic Surgery for Hyperplasia and Hypertrophy of Labia Minor 2022 Edition", the distance between the front lip and the back lip of the labia minora has a golden ratio); the joint part is connected to each component by a rivet-like screw; the handle part is divided into two sections, the proximal joint section and the distal joint section. The proximal joint section is designed as a deformable elastic metal sheet to achieve the "two-stage" control effect described later, and the distal joint section is a non-deformable hollow design to achieve the "embedded" design effect described later. ② The middle partition is composed of three parts: the head, the joint part, and the tail. The shape of the head is the same as the shape of the pliers head and the pliers page of the design pliers, which is used to separate the labia minora on both sides; the joint part is placed between the left and right design pliers pages; the tail uses two compression springs to connect and fix the proximal joint sections of the left and right design pliers handles to achieve the centering effect.
[0011] The resection shear functional unit is composed of two left and right scissors, each of which is composed of three parts: a head, a joint, and a tail. The curvature of the head scissors is the same as the curvature of the arc edge of the aforementioned design pliers. The joint is connected by the aforementioned rivet-like screws, and the tail is composed of a long metal handle with a rectangular cross-section, which is embedded in the hollow handle of the distal joint segment of the aforementioned design pliers to achieve the "two-stage" sequential linkage control effect described later.
[0012] The upper and lower three-dimensional coaxial layout of the two functional units is that the joints of the five components of the right leaf design pliers, middle partition, left leaf design pliers, right leaf scissors, and left leaf scissors are connected in sequence with the same rivet-like screw as the common axis to achieve the effect of retaining the bottom of the labia minora and removing the free edge of the labia minora in a synchronous and non-displacement state.
[0013] The "embedded" design of the shared handle is to embed the scissor handle of the excision shear functional unit into the handle of the "hollow" design clamp functional unit to simplify the control operation. The "hollow" is to introduce a handle cover similar to a "battery compartment cover" at the bottom of the handle to eliminate the "dead space" to reduce the difficulty of industrial manufacturing and postoperative cleaning and disinfection of the plastic surgery shears. The fixation and linkage of the two handles after nesting are described in the "two-stage" control implementation method described below.
[0014] The "two-stage" control of the common handle is cleverly achieved by introducing two simple designs: two groups of springs with different compression forces F in each group of embedded handles, and a deformable elastic metal sheet in the near-joint section of the designed pliers handle: ① The spring with a compression force of 2F is placed on the inner side of the resection shear handle in the hollow cavity, and the spring with a compression force F is placed on the outer side of the resection shear handle in the hollow cavity. The lever effect is achieved by means of the coaxiality of the joint part, so that the head end of the designed pliers is biased to the inner side and the head end of the resection shear is biased to the outer side when the head of the plastic shears is stationary, thereby creating a spatial possibility for "two-stage" control; ② The introduction of the deformable elastic metal sheet assembly of the designed pliers handle allows the plastic shears to continue to apply force when the designed pliers "close their mouths" in the working state, and the designed pliers handle is deformed, resulting in a temporal possibility for "two-stage" control. At this time, the non-deformable resection shear handle is subjected to the heavy clamping force, causing the resection shear head to generate a shear force, thereby realizing the cutting effect.
[0015] The head of the plastic surgery scissors is folded upward near the joint to form an angle of 60° with the horizontal line. This allows the operating part of the plastic surgery scissors to be located at the bottom of the surgical field to achieve unobstructed operation, and ensures that the plastic surgery scissors have a positive shear force of cos60° in the horizontal direction.
[0016] (3) Beneficial effects:
[0017] The embedded two-stage plastic scissors for edge-method labia minora excision surgery provided by the present invention facilitate doctors to easily design and finely adjust the ideal bilaterally symmetrical golden ratio labia minora by lightly clamping the handle without the assistance of an assistant and in a natural tension-free state, just like using a camera shutter button, and then by re-clamping in a non-displaced state, synchronously and uninterruptedly cut off the redundant labia minora tissue, thereby improving the embarrassment of "inconsistent effects before and after" caused by the asynchronous design and excision in previous surgeries, and improving the accuracy and efficiency of the surgery, and improving the benefits and satisfaction of patients. In addition, whether it is a bilateral excision for labia minora hypertrophy or a unilateral excision for asymmetric labia minora, the plastic scissors have correspondingly better clinical value.
