Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a membrane-breaking forceps with a splash guard. Background Technology
[0002] Artificial rupture of membranes is a common procedure during childbirth in obstetrics and gynecology. Currently, forceps are mainly used clinically for this purpose. The procedure involves using the clamps at the tip of the forceps to grasp the amniotic membrane and pull it outwards, creating a rupture and allowing amniotic fluid to flow out. However, existing forceps have significant drawbacks. When the pressure inside the amniotic sac is high, such as when the amniotic sac is bulging, the amniotic fluid can gush out instantly and spray everywhere after rupture with forceps. This can easily splash onto the faces and bodies of medical staff, causing hygiene problems and potentially posing a risk of infection, thus threatening their health. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a membrane breaking clamp with a splash guard.
[0004] To solve the above-mentioned technical problems, the present invention provides a membrane-breaking clamp with a splash guard, comprising a first clamp body, a second clamp body, and a shield. The first clamp body and the second clamp body are rotatably connected by a connecting device. The first clamp body includes a first clamp handle and a first clamp head and a first clamp handle disposed at both ends of the first clamp handle. The second clamp body includes a second clamp handle and a second clamp head and a second clamp handle disposed at both ends of the second clamp body. One end of the shield is an open end, and the other end of the shield is provided with a sliding groove distributed radially along the open end. The first clamp head and the second clamp head protrude from the open end through the sliding groove. Sliding elements are provided on both the first clamp handle and the second clamp handle. The first clamp handle and the second clamp handle are slidably connected in the sliding groove along the length direction of the sliding groove through the sliding elements.
[0005] Furthermore, the two side walls of the slide groove are respectively provided with a first through groove and a second through groove along the length direction of the slide groove, and the first clamp and the second clamp are respectively provided with assembly holes at the positions corresponding to the first through groove and the second through groove; the sliding component includes a connecting shaft and a first limiting block and a second limiting block provided at both ends of the connecting shaft, the connecting shaft passes through the first through groove, the assembly hole and the second through groove, and the first limiting block and the second limiting block are respectively provided on the outside of the two side walls of the slide groove.
[0006] Furthermore, the first limiting block is fixedly connected to one end of the connecting shaft, and the second limiting block is detachably connected to the other end of the connecting shaft; or both the first limiting block and the second limiting block are detachably connected to both ends of the connecting shaft.
[0007] Furthermore, both ends of the slide are provided with limiting parts. The limiting parts can prevent the first clamp handle and the second clamp handle from moving toward the two ends of the slide in a natural state. When the first clamp handle and the second clamp handle are subjected to external force, they can squeeze the limiting parts and move toward the two ends of the slide.
[0008] Furthermore, the limiting part includes a first limiting pad and a second limiting pad, the first limiting pad and the second limiting pad are disposed opposite to each other in the two side walls of the slide groove and there is a gap between the first limiting pad and the second limiting pad.
[0009] Furthermore, both the first and second limiting pads are made of elastic rubber material.
[0010] Furthermore, the shield is made of a transparent material.
[0011] Furthermore, a locking mechanism is provided between the first clamp handle and the second clamp handle, and the locking mechanism is located between the connecting device and the first clamp handle and the second clamp handle.
[0012] Furthermore, the locking mechanism includes a first engaging tooth connected to the first clamp handle and extending toward the second clamp handle, and a second engaging tooth connected to the second clamp handle and extending toward the first clamp handle, which is adapted to the first engaging tooth. The first clamp handle and the second clamp handle can be engaged and connected through the first engaging tooth and the second engaging tooth.
[0013] Furthermore, both the first and second clamp handles are ring-shaped structures.
[0014] This invention relates to a membrane rupture forceps with a splash guard. By incorporating the guard, when using the forceps for manual membrane rupture, especially under conditions of high pressure within the amniotic sac and easy splashing of amniotic fluid, the guard effectively blocks the sudden outflow and splashing of amniotic fluid, preventing it from splashing onto the faces and bodies of medical personnel. This solves the hygiene problems associated with existing membrane rupture forceps, reduces the potential infection risk for medical personnel, and protects their health. The design of the sliding groove, sliding component, and limiting part ensures a stable and reliable sliding connection between the first and second forceps bodies within the guard. The cooperation between the first and second through grooves on both sides of the sliding groove and the sliding component, as well as the limitation of the forceps handle movement by the limiting part, ensures the structural stability of the membrane rupture forceps during operation, facilitating precise operation by medical personnel. The limiting part can prevent the movement of the first and second forceps handles in a natural state, but can be squeezed under external force to allow the handles to move. This design ensures the relative fixation of the forceps body position during normal operation, while allowing flexible adjustment of the forceps body position in special circumstances to adapt to different membrane rupture needs.

Detailed Implementation
[0021] The following detailed implementation methods further illustrate the following:
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 This utility model discloses a film-breaking forceps with a splash guard, comprising a first forceps body 1, a second forceps body 2, and a guard 3. The first forceps body 1 and the second forceps body 2 are rotatably connected by a connecting device 4. The first forceps body 1 includes a first handle 11 and a first jaw 12 and a first clamp 13 disposed at both ends of the first jaw 11. The second forceps body 2 includes a second handle 21 and a second jaw 22 and a second clamp 23 disposed at both ends of the second jaw 21. In this embodiment, both the first clamp 13 and the second clamp 23 are annular structures. The operator passes their fingers through the annular structure of the first clamp 13 and the second clamp 23 and grips them to perform the film-breaking operation, adjusting the grip strength as needed. The annular structure of the first clamp 13 and the second clamp 23 facilitates the operator's grip, better conforming to the hand compared to other shapes of clamp handles, providing a more comfortable grip experience. It facilitates the application of force, allowing the operator to more effectively control the movement of the first jaw 12 and the second jaw 22, improving the accuracy and efficiency of the film-breaking operation.
[0023] To facilitate storage after use, a locking mechanism 7 is provided between the first clamp handle 11 and the second clamp handle 21, located below the connecting device 4. The locking mechanism 7 includes a first engaging tooth 71 connected to the first clamp handle 11 and extending towards the second clamp handle 21, and a second engaging tooth 72 connected to the second clamp handle 21 and extending towards the first clamp handle 11, which is adapted to the first engaging tooth 71. The first clamp handle 11 and the second clamp handle 21 are connected by the first engaging tooth 71 and the second engaging tooth 72. The first engaging tooth 71 and the second engaging tooth 72 are offset relative to each other. During use, separating the first engaging tooth 71 and the second engaging tooth 72 allows the first clamp handle 11 and the second clamp handle 21 to rotate around the connecting device 4. After use, the first engaging tooth 71 and the second engaging tooth 72 lock the first clamp handle 11 and the second clamp handle 21 in place, preventing further rotation and facilitating storage.
[0024] In this embodiment, the shield 3 is made of transparent material, specifically PVC plastic. When using the film-breaking pliers to break the film, the operator can clearly observe the contact between the first pliers head 12 and the second pliers head 22 and the film, as well as the film-breaking process, through the transparent shield 3. The transparent shield 3 facilitates the operator in accurately aligning the film-breaking pliers with the film-breaking position, improving the accuracy of film breaking. It allows for real-time observation of the film-breaking effect, timely adjustment of the film-breaking force and position, and ensures the quality of film breaking. One end of the shield 3 is an open end 31, and the other end of the shield 3 is provided with a sliding groove 32 radially distributed along the open end 3. The first pliers head 12 and the second pliers head 22 protrude from the open end 31 through the sliding groove 32. The first pliers handle 11 and the second pliers handle 21 are both provided with sliding elements 5, and the first pliers handle 11 and the second pliers handle 21 are slidably connected to the sliding groove 32 along the length direction of the sliding groove 32 through the sliding elements 5.
[0025] To enable the first clamp handle 11 and the second clamp handle 21 to slide within the slide groove 32, in this embodiment, a first through groove 321 and a second through groove 322 are respectively provided on the two side walls of the slide groove 32 along the length of the slide groove 32. Mounting holes 6 are provided at the positions of the first clamp handle 11 and the second clamp handle 21 corresponding to the positions of the first through groove 321 and the second through groove 322. In this embodiment, the sliding member 5 includes a connecting shaft 51 and a first limiting block 52 and a second limiting block 53 located at both ends of the connecting shaft 51. The connecting shaft 51 passes through the first through groove 321, the mounting hole 6, and the second through groove 322. The first limiting block 52 and the second limiting block 53 are respectively located outside the two side walls of the slide groove 32 and abut against the two side walls of the slide groove 32. When installing the sliding member 5, one end of the connecting shaft 51 is passed through the first through groove 321, then through the mounting hole 6 on the first clamp handle 11 or the second clamp handle 21, and then through the second through groove 322. A first limiting block 52 is installed at one end of the connecting shaft 51 that extends out of the first through groove 321, and a second limiting block 53 is installed at one end of the connecting shaft 51 that extends out of the second through groove 322, so that the first limiting block 52 and the second limiting block 53 abut against the two side walls of the slide groove 32, respectively. When using the membrane-breaking forceps, when the first clamp handle 13 and the second clamp handle 23 are squeezed or opened, the sliding member 5 will slide along the length of the slide groove 32 within the first through groove 321 and the second through groove 322. The first limiting block 52 and the second limiting block 53 restrict the position of the connecting shaft 51 within the first through groove 321 and the second through groove 322, preventing the connecting shaft 51 from disengaging and ensuring the stability of the sliding connection between the first clamp handle 11 and the second clamp handle 21 and the cover 3 during use. In this embodiment, since the sliding member 5 moves in a curved motion when the first clamp 11 and the second clamp 21 are opened or closed, both the first through groove 321 and the second through groove 322 are arc-shaped grooves that are adapted to the remote movement trajectory of the sliding member 5.
[0026] To facilitate the installation and disassembly of the sliding component 5, the first limiting block 52 can be fixedly connected to one end of the connecting shaft 51, and the second limiting block 53 can be detachably connected to the other end of the connecting shaft 51. During installation, first pass the connecting shaft 51 through the first through groove 321, the mounting hole 6, and the second through groove 322, then install the second limiting block 53 at the end of the connecting shaft 51 that extends out of the second through groove 322. Disassembly is performed in reverse. Alternatively, the first limiting block 52 and the second limiting block 53 can be designed to be detachably connected to both ends of the connecting shaft 51. In this method, during installation, the connecting shaft 51 is passed through the first through groove 321, the mounting hole 6, and the second through groove 322 in sequence, and then the first limiting block 52 and the second limiting block 53 are installed respectively. During disassembly, first remove the first limiting block 52 and the second limiting block 53, then pull out the connecting shaft 51. In this embodiment, the first limiting block 52 and the second limiting block 53 are detachably connected to both ends of the connecting shaft 51. Specifically, both ends of the connecting shaft 51 are provided with external threads, and the first limiting block 52 and the second limiting block 53 are both nuts. The detachability of the first limiting block 52, the second limiting block 53, and the connecting shaft 51 is achieved by connecting the nuts with the external threads. This design allows the cover 3 to be disassembled for cleaning or replacement, reducing usage costs.
[0027] Since the slider 5 can slide freely in the groove 32, in order to limit the sliding of the first clamp handle 11 and the second clamp handle 21 to the two ends of the groove 32, in this embodiment, limiting portions 323 are provided at both ends of the groove 32. The limiting portions 323 can, in their natural state, prevent the first clamp handle 11 and the second clamp handle 21 from moving toward the two ends of the groove 32; when the first clamp handle 11 and the second clamp handle 21 are subjected to external force, they can compress the limiting portions 323 and move toward the two ends of the groove 32. Specifically, the limiting portions 323 include a first limiting pad 3231 and a second limiting pad 3232, which are disposed opposite to each other within the side walls of the groove 32, with a gap between them. In their natural state, the limiting portions 323 prevent the first clamp handle 11 and the second clamp handle 21 from moving toward the two ends of the groove 32, ensuring that the first clamp head 12 and the second clamp head 22 are always near the center of the cover 3. This design allows medical personnel to use the membrane-breaking forceps without frequently adjusting the forceps head position, ensuring that the shield 3 provides extensive protection against splashes during membrane breaking. This significantly improves the convenience of the membrane breaking operation, reduces operational steps, and allows medical personnel to focus more on the membrane breaking task itself, thus improving work efficiency. In special situations, such as when a larger operating stroke is required to handle complex membrane breaking needs, the first forceps handle 11 and the second forceps handle 21 can be compressed by external force to the limiting part 323 and move towards both ends of the slide groove 32. This design ensures the optimal shielding effect of the shield 3 in daily membrane breaking operations while also taking into account the operating stroke requirements in special situations, demonstrating the flexibility and practicality of the membrane-breaking forceps design. The limiting part 323 maintains the ideal position of the first forceps head 12 and the second forceps head 22 within the shield 3, ensuring the stable operation of the membrane-breaking forceps' splash-proof function, creating safer and more hygienic operating conditions for medical personnel, reducing the risk of infection caused by splashes, and strongly supporting the smooth progress of medical work. In this embodiment, both the first limiting pad 3231 and the second limiting pad 3232 are made of elastic rubber material. When the first clamp handle 11 and the second clamp handle 21 press against the limiting part 323, the elastic rubber undergoes elastic deformation, providing cushioning. The cushioning effect of the elastic rubber material reduces the rigid impact of the first clamp handle 11 and the second clamp handle 21 on the limiting part 323, further extending the service life of the limiting part 323. The elastic rubber material has a certain frictional force, which better maintains the limiting effect of the limiting part 323 on the first clamp handle 11 and the second clamp handle 21 under natural conditions, preventing it from moving due to slight shaking.
[0028] The working principle of this utility model of a membrane rupture forceps with a splash guard is as follows: During use, the operator opens the first and second locking teeth of the locking mechanism. The medical staff holds the first and second handles with both hands respectively. Based on the lever principle, squeezing or opening the handles causes the first and second handles to rotate around the connecting device, driving the first and second clamp heads to puncture and rupture the amniotic membrane. Simultaneously, the sliding parts on the first and second handles are slidably connected to the grooves of the guard, facilitating adjustment of the clamp head position to meet different membrane rupture needs. During the membrane rupture process, the open end of the guard covers the vaginal opening, physically preventing fluid splashing.
[0029] This utility model discloses a membrane rupture forceps with a splash guard, which has the following beneficial effects: By setting up the guard, when using the forceps for artificial membrane rupture, especially when the pressure inside the amniotic membrane is high and amniotic fluid is prone to splashing, the guard can effectively block the amniotic fluid that surges out and splashes everywhere, preventing amniotic fluid from splashing onto the face and body of medical personnel. This solves the hygiene problems encountered during the use of existing membrane rupture forceps, reduces the potential infection risk for medical personnel, and protects their health. The design of the sliding groove, sliding component, and limiting part ensures a stable and reliable sliding connection between the first and second forceps within the guard. The cooperation between the first and second through grooves on both sides of the sliding groove and the sliding component, as well as the limitation of the forceps handle movement by the limiting part, ensures the structural stability of the membrane rupture forceps during operation, facilitating precise operation by medical personnel. The limiting part can block the movement of the first and second forceps handles in a natural state, but can be squeezed to allow the forceps handles to move under external force. This design ensures the relative fixation of the forceps position during normal operation, while allowing flexible adjustment of the forceps position in special circumstances to adapt to different membrane rupture needs.
[0030] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
