Description

Technical Field

[0001] This utility model relates to the field of auxiliary instruments for skin surgery, and in particular to a soft skin clamping and fixing device for surgery. Background Technology

[0002] During dermatological surgery, when dealing with soft or loose skin, the force applied by the scalpel during incision can cause indentation. Furthermore, excessive force can easily lead to an incision depth exceeding the expected limit, potentially damaging vital subcutaneous structures such as blood vessels and nerves. In clinical practice, to facilitate surgical procedures and subsequent wound suturing, medical staff often pinch the skin in the surgical area with their fingers. However, this method makes it highly susceptible to accidental cuts from the scalpel or punctures from suture needles during the actual surgical procedure and wound suturing, posing a potential risk of infectious disease infection. Therefore, fixation forceps are typically used to immobilize the skin. However, most fixation forceps only provide fixation by holding the skin in place and lack the ability to maintain a fixed position; while some can maintain a fixed position, they cannot adjust the thickness of the skin fixation. Utility Model Content

[0003] The technical problem to be solved by this invention is to provide a surgical soft skin clamping and fixing device that can adjust the thickness of the clamped skin.

[0004] To address the aforementioned problems, this utility model provides a surgical soft skin clamping and fixing device. The device includes a first fixing arm and a second fixing arm for clamping and fixing the skin, a first spring for keeping the front ends of the first and second fixing arms open, and a locking mechanism for maintaining the distance between the front ends of the first and second fixing arms. The locking mechanism includes an adjusting rod for connecting the first and second fixing arms, a retainer for fixing the adjusting rod to the second fixing arm, and a second spring for resetting the retainer. One end of the adjusting rod is pivotally connected to the first fixing arm, and the other end passes through the second fixing arm. The retainer is slidably disposed within the second fixing arm, and a pushing part is provided on the retainer, which passes through the second fixing arm and is exposed outside the second fixing arm.

[0005] Furthermore, the second fixed arm is provided with a receiving groove for accommodating the card seat and the second spring, and an unlocking opening for the pushing part to pass through. The unlocking opening is connected to the receiving groove. The second fixed arm is also provided with a clearance opening, and the adjusting rod passes through the clearance opening. The receiving groove is connected to the clearance opening.

[0006] Furthermore, the card holder is provided with a slot for holding and fixing the adjustment rod.

[0007] Furthermore, the card holder is provided with a card holding piece, and the card slot is provided on the card holding piece.

[0008] Furthermore, the top surface of the pushing part is an inclined surface.

[0009] Furthermore, it also includes a protective sleeve for protecting the skin, with protective sleeves provided on both the first and second fixing arms.

[0010] Furthermore, both the first and second fixed arms are provided with mounting parts, the length and width of which are less than the length and width of the first and second fixed arms. Both the first and second fixed arms are detachably equipped with anti-detachment mechanisms to prevent the protective sleeve from falling off.

[0011] Furthermore, the mounting part is provided with a card interface and a mounting slot. The card interface is connected to the mounting slot, the mounting slot is used to accommodate the anti-detachment mechanism, and the card interface is used to cooperate with the anti-detachment mechanism to fix the anti-detachment mechanism on the mounting part.

[0012] Furthermore, the anti-detachment mechanism includes a baffle, an anti-detachment body, and an elastic buckle. The elastic buckle and the baffle are both provided on the anti-detachment body. The anti-detachment body is used to be inserted into the mounting groove, the baffle is used to block the protective sleeve, and the elastic buckle is used to engage with the card interface.

[0013] Furthermore, the anti-detachment mechanism includes a baffle and an anti-detachment body, the anti-detachment body being inserted into the mounting groove with an interference fit, and the baffle being disposed on the anti-detachment body.

[0014] This utility model discloses a surgical soft skin clamping and fixing device. One end of an adjusting rod is pivotally connected to a first fixing arm, and the other end of the adjusting rod passes through a second fixing arm. The adjusting rod is fixed by the cooperation of a second spring, a retaining seat, and the second fixing arm, thereby maintaining the distance between the front ends of the first and second fixing arms.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, a preferred embodiment of the surgical soft skin clamping and fixing device of this utility model includes a first fixing arm 1, a second fixing arm 2, a protective sleeve 3, a first spring 4, and a locking mechanism 5. The first fixing arm 1 and the second fixing arm 2 are pivotally connected at the middle. The first fixing arm 1 and the second fixing arm 2 are used to clamp and fix the skin. Applying force to the rear ends of the first fixing arm 1 and the second fixing arm 2 towards the middle between the first fixing arm 1 and the second fixing arm 2 allows the first fixing arm 1 and the second fixing arm 2 to move in opposite directions. The two ends of the first spring 4 are respectively provided on the first fixing arm 1 and the second fixing arm 2. The first spring 4 is used to reset the first fixing arm 1 and the second fixing arm 2, so that the front ends of the first fixing arm 1 and the second fixing arm 2 can be opened when released. The locking mechanism 5 is used to lock the distance between the rear ends of the first fixing arm 1 and the second fixing arm 2, so that the front ends of the first fixing arm 1 and the second fixing arm 2 are kept in the corresponding position, and the skin can be continuously clamped and fixed. The protective sleeve 3 is detachably installed on both the first fixing arm 1 and the second fixing arm 2. The protective sleeve 3 is made of a flexible material, such as silicone, to protect the skin.

[0025] like Figures 1 to 3As shown, the first fixing arm 1 is provided with a mounting part 6. The length and width of the mounting part 6 are smaller than the length and width of the first fixing arm 1, thus forming a positioning step at the connection between the mounting part 6 and the first fixing arm 1. The positioning step is used to position the rear end of the protective sleeve 3. A detachable anti-detachment mechanism 7 is detachably mounted on the first fixing arm 1. The anti-detachment mechanism 7 is used to prevent the protective sleeve 3 from falling off the mounting part 6 of the first fixing arm 1; that is, the anti-detachment mechanism 7 is used to position the front end of the protective sleeve 3. The mounting part 6 is provided with a locking interface 61 and a mounting groove 62. The locking interface 61 connects to the mounting groove 62, and the mounting groove 62 is used to accommodate the anti-detachment mechanism 7. The locking interface 61 cooperates with the anti-detachment mechanism 7 so that the anti-detachment mechanism 7 can be locked onto the mounting part 6. The mounting part 6 and the anti-detachment mechanism 7 provide stable fixation for the protective sleeve 3. The second fixing arm 2 is also provided with the same mounting part 6 and anti-detachment structure.

[0026] The anti-detachment mechanism 7 includes a baffle 71, an anti-detachment body 72, and an elastic buckle 73. Both the elastic buckle 73 and the baffle 71 are mounted on the anti-detachment body 72. The anti-detachment body 72 is inserted into the mounting groove 62. The baffle 71 blocks the protective sleeve 3. The elastic buckle 73 engages with the first fixing arm 1 or the second fixing arm 2. The elastic buckle 73 improves the stability of the connection between the anti-detachment mechanism 7 and the mounting part 6. The anti-detachment body 72, the baffle 71, and the elastic buckle 73 are typically integrally formed, reducing assembly steps. The width and height of the baffle 71 are greater than the height and width of the mounting part 6. It should be noted that, generally, the outline of the baffle 71 on the side closest to the middle of the first fixing arm 1 and the second fixing arm 2 will not exceed the outline of the protective sleeve 3 on that side, ensuring that the minimum clamping distance of the protective sleeve 3 is 0. Of course, in other embodiments, only one aspect needs to be greater than the baffle 71, i.e., the width or height of the baffle 71 is greater than the corresponding height or width of the mounting part 6. The elastic buckle 73 has a spring piece 731 and a locking part 732. The locking part 732 is disposed on the spring piece 731, and the thickness of the locking part 732 is the same as the depth of the locking interface 61. This ensures that the locking part 732 does not protrude from the mounting part 6 and does not lift the protective sleeve 3, making the surface of the protective sleeve 3 smooth and preventing discomfort to the patient. It should be noted that the protective sleeve 3 located on the side of the locking interface 61 is thinner, making it easier to press the locking part 732 to deform the spring piece 731, thereby allowing the locking part 732 to detach from the locking interface 61. The top surface of the locking part 732 is inclined, with the end closer to the baffle 71 being higher and the end further away from the baffle 71 being lower. This allows the locking part 732 to be automatically pushed towards the baffle 71 when the squeezing part is pressed, thereby pushing the entire anti-detachment mechanism 7.

[0027] like Figure 4and Figure 5 As shown, the locking mechanism 5 includes an adjusting rod 51, a retaining seat 52, and a second spring 53. One end of the adjusting rod 51 is pivotally connected to the first fixed arm 1, and the other end of the adjusting rod 51 passes through the second fixed arm 2. The retaining seat 52 is slidably disposed within the second fixed arm 2. The second spring 53 is used to reset the retaining seat 52, so that the retaining seat 52 applies a force perpendicular to the axial direction of the adjusting rod 51 to the adjusting rod 51, thereby fixing the adjusting rod 51 to the second fixed arm 2, thus determining the distance between the first fixed arm 1 and the second fixed arm 2, that is, keeping the first fixed arm 1 and the second fixed arm 2 in a state of clamping and fixing the skin.

[0028] Specifically, a connecting plate is provided on the first fixed arm 1, and a connecting opening 21 is provided at the end of the adjusting rod 51 away from the anti-detachment mechanism 7. The connecting plate is inserted into the connecting opening 21, and the connecting plate is connected to the adjusting rod 51 through a shaft. In this way, the first fixed arm 1 and the adjusting rod 51 are pivotally connected, so that the adjusting rod 51 can deflect around the point of connection with the first fixed arm 1, thereby allowing the adjusting rod 51 to adapt to the rotation of the first fixed arm 1 and the second fixed arm 2. The second fixed arm 2 is provided with an clearance opening, which passes through the second fixed arm 2 along the axis of the adjusting rod 51, and the adjusting rod 51 passes through the clearance opening; the second fixed arm 2 is also provided with an unlocking opening 23 at one end of the connecting opening 21, and the second fixed arm 2 is also provided with a receiving groove 22, which is arranged along the length direction of the second fixed arm 2 and is formed by recessing from one end of the second fixed arm 2 to the other end. The card seat 52 and the second spring 53 are both provided in the receiving groove 22, one end of the second spring 53 abuts against the bottom of the receiving groove 22, and the other end of the second spring 53 abuts against On the card holder 52, the receiving groove 22 communicates with the connecting opening 21, thus ensuring that the card holder 52 can abut against the adjusting rod 51. The card holder 52 is provided with a pushing part 521, which is used to push the card holder 52 to move, thereby changing the position of the card holder 52 and unlocking the adjusting rod 51, allowing the adjusting rod 51 to move within the connecting opening 21. The unlocking opening 23 communicates with the receiving groove 22, so that the pushing part 521 of the card holder 52 can protrude from the second fixing arm 2, facilitating the thumb to push the card holder 52. The top surface of the pushing part 521 is inclined, facilitating the pushing of the pushing part 521. The card holder 52 is provided with a card slot, which is used to hold the adjusting rod 51. The adjusting rod 51 is typically made of a material that increases friction, such as rubber or silicone, ensuring that the card holder 52 and the second fixing arm 2 can stably hold the adjusting rod 51. In other embodiments, the card holder 52 is provided with a retaining piece and a card slot is provided on the retaining piece. This reduces the contact area between the card slot and the adjusting rod 51. When the force applied by the card holder 52 to the adjusting rod 51 remains unchanged, the reduced contact area increases the pressure, thereby making the adjusting rod 51 more securely fixed.

[0029] In use, first hold the first fixing arm 1 and the second fixing arm 2, and use your thumb to push the card holder 52 towards the front to unlock the adjusting rod 51. Then, while keeping the adjusting rod 51 unlocked, press the rear end of the first fixing arm 1 and the second fixing arm 2, so that the front end of the first fixing arm 1 and the second fixing arm 2 is closed, and the skin to be clamped and fixed is fixed. After the skin is clamped and fixed, release the card holder 52. The card holder 52 is reset under the action of the second spring 53, so that the adjusting rod 51 is fixed on the second fixing arm 2, thereby fixing the first fixing arm 1 and the second fixing arm 2, realizing the fixation of the skin without the need for medical staff to hold it continuously.

[0030] An adjusting rod 51, a retaining seat 52, and a second spring 53 are provided. The second spring 53 ensures that the retaining seat 52 always applies a force to the adjusting rod 51, fixing the adjusting rod 51 to the second fixing arm 2. When the retaining seat 52 unlocks the adjusting rod 51, the second fixing arm 2 can move freely on the adjusting rod 51. Moving the second fixing arm 2 changes the distance between the second fixing arm 2 and the first fixing arm 1. The retaining seat 52 can move to any position on the adjusting rod 51, allowing the second fixing arm 2 to move the retaining seat 52 to any position on the adjusting rod 51, thus securing the adjusting rod 51 at any position and adapting to skin of different thicknesses.

That is, the anti-detachment mechanism 7 includes a baffle 71 and an anti-detachment body 72. The anti-detachment body 72 is inserted into the mounting groove 62 with an interference fit. The anti-detachment mechanism 7 is connected to the mounting part 6 by the interference fit. The baffle 71 is provided on the anti-detachment body 72.
