Perianal perineal skin traction fixation patch

Abstract

This utility model discloses a perianal and perineal skin traction and fixation patch, comprising a long strip-shaped main body and claw-shaped parts. The long strip-shaped main body and claw-shaped parts are coated with medical pressure-sensitive adhesive. The long strip-shaped main body extends continuously from one end to the other and branches into multiple branches to form the claw-shaped parts. These multiple branches extend outwards to both sides, forming a symmetrical or asymmetrical expansion layout, thereby increasing the contact area with the skin to accommodate the muscles of the buttocks, outer thighs, and lateral abdominal walls. This utility model, through its claw-shaped design, meets the mechanical requirements of perianal and perineal skin traction. It can be used unilaterally or bilaterally depending on the surgical needs. In use, the branches of the traction patch are first attached to the skin adjacent to the perianal and perineal area. Then, after applying appropriate traction force, a single branch is attached to the buttocks, outer thighs, or lateral abdominal walls. This facilitates exposure of the surgical field, fixes the skin, adapts to various surgical positions, facilitates operation, and reduces the burden on the surgeon.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a perianal and perineal skin traction and fixation patch. Background Technology

[0002] Proctology, urology, and gynecology surgeries often involve the anus and perineum. To fully expose the surgical field, these surgeries often employ the lithotomy, pliers, or lateral decubitus positions. Even so, the surgeon or assistant still needs to use their hands or instruments to pull the perianal and buttock skin outwards during the procedure to achieve full exposure of the anus and perineum. This can lead to physical exhaustion for both the surgeon and assistant, as well as skin damage from instrument clamping. Secondly, exposing the surgical field directly by hand or through instrument clamping and pulling during the procedure is unstable, especially during prolonged surgeries, easily causing fatigue for the surgeon or assistant and affecting the stability of the surgical procedure. Thirdly, proctology, urology, and gynecology surgeries often employ the lithotomy or pliers positions. These positions result in limited space for the surgeon and assistant. Ideally, the surgeon and one assistant should participate in the surgery, but to better expose the surgical field, an additional assistant is often needed specifically for pulling and exposing the surgical field. Furthermore, the assistant's position during the procedure is often cramped.

[0003] Therefore, we propose a perianal and perineal skin traction and fixation patch to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a perianal and perineal skin traction and fixation patch to overcome the above-mentioned defects in the prior art.

[0005] The technical solution to achieve the purpose of this utility model is: a perianal and perineal skin traction and fixation patch, comprising a long strip main body and claws, wherein the long strip main body and claws are coated with medical pressure-sensitive adhesive; the long strip main body extends continuously from one end to the other end and branches into multiple branches to form the claws, wherein the multiple branches of the claws extend outward to both sides to form a symmetrical or asymmetrical expansion layout, thereby increasing the contact area with the skin to adapt to the muscles of the buttocks, outer thighs, and lateral abdominal wall.

[0006] In a preferred embodiment, the claw portion consists of three independent branch strips, including a first branch strip, a second branch strip, and a third branch strip; the first branch strip extends obliquely to one side from the elongated main body; the second branch strip extends along the center line of the elongated main body; and the third branch strip extends obliquely to the other side from the elongated main body.

[0007] In a preferred embodiment, the first branch and the third branch are symmetrically distributed along the center line of the elongated main stem.

[0008] In a preferred embodiment, the elongated main body and claws are made of polyurethane film.

[0009] In a preferred embodiment, the length of the elongated main stem is between 20cm and 30cm, and the width is between 6cm and 10cm.

[0010] In a preferred embodiment, the first and third branch bars are parallelograms with a long side between 5cm and 10cm and a short side between 2cm and 3cm; the second branch bar is a rectangle with a length between 5cm and 10cm and a width between 2cm and 3cm.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] (1) This utility model, through its "claw" design, meets the mechanical requirements of traction of the perianal and perineal skin. It can be used on one or both sides as needed for surgery. When using it, first stick the branch of the traction patch to the skin near the perianal and perineal area, and then apply the corresponding force to pull it. Then stick the single branch to the buttocks, outer thigh, and lateral abdominal wall. This facilitates the exposure of the surgical field, fixes the skin, adapts to various surgical positions, facilitates operation, and reduces the burden on doctors.

[0013] (2) The present invention has three independent branch strips, which conform to the human perianal structure and have a better fixation effect.

[0025] (Example 1)

[0026] See Figure 1A perianal and perineal skin traction and fixation patch includes a long strip-shaped main body 1 and claw-shaped parts 2. The long strip-shaped main body 1 extends continuously from one end to the other end and branches into three branches to form claw-shaped parts 2. Claw-shaped parts 2 are composed of three independent branches, including a first branch 2-1, a second branch 2-2, and a third branch 2-3. The first branch 2-1 extends obliquely to one side from the long strip-shaped main body 1. The second branch 2-2 extends along the center line of the long strip-shaped main body 1. The third branch 2-3 extends obliquely to the other side from the long strip-shaped main body 1, thereby increasing the contact area with the skin to accommodate the muscles of the buttocks, outer thighs, and lateral abdominal wall. The first branch 2-1 and the third branch 2-3 are symmetrically distributed along the center line of the long strip-shaped main body 1. With its claw-shaped design, it meets the mechanical requirements of perianal and perineal skin traction. Depending on the surgical needs, it can be used unilaterally or bilaterally. When using it, first stick the branch of the traction patch to the skin near the perianal and perineal area, and then apply the appropriate force to pull it. Then stick the branch to the buttocks, outer thigh, or lateral abdominal wall. This facilitates exposure of the surgical field, fixes the skin, adapts to various surgical positions, facilitates operation, and reduces the burden on doctors.

[0027] Furthermore, the main stem is 30cm long and 10cm wide. The first branch 2-1 and the third branch 2-3 are parallelograms with a long side of 10cm and a short side of 3cm; the second branch 2-2 is a rectangle with a length of 10cm and a width of 3cm. The design of these three independent branch strips, with lengths conforming to the structure of the human perineum, provides better fixation. Different sizes can be selected to suit different body types.

[0028] Furthermore, the elongated main body 1 and claw 2 are made of polyurethane membrane, and are coated with medical pressure-sensitive adhesive. The polyurethane membrane has excellent elasticity and flexibility, is waterproof and breathable, and possesses good tear and abrasion resistance.
