[0001] This utility model relates to the field of medical device technology, and in particular to an obstetric forceps for childbirth. Background Technology

[0002] Forceps delivery is an obstetric procedure that uses obstetric forceps to apply traction or rotational force to correct fetal head position, assist in fetal head descent, and facilitate fetal delivery. Obstetric forceps typically consist of two blades, each with a corresponding handle for easy gripping and manipulation by the surgeon. The forceps are designed to fit snugly against the fetal head while minimizing injury to both the fetus and the mother. Most existing two-blade forceps are scissor-type, requiring manual holding while clamping, necessitating precise application of force. This procedure demands a high level of skill and is quite challenging.

[0003] Therefore, we propose a type of obstetric forceps for childbirth to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 An obstetric forceps for childbirth includes a core column 1. Two clamps 2 are symmetrically arranged at one end of the core column 1. Each clamp 2 has clamp shanks 3, which are rotatably connected to the end face of the core column 1, allowing the clamps 2 to open and close normally for clamping. A spring 4 is fixedly connected to the opposite side of the clamp shanks 3, keeping the clamps 2 in an open state. A collar 5 is fitted onto the front end of the core column 1, sliding onto the clamp shanks 3. Pushing the collar 5 forward causes it to slide onto the clamp shanks 3, compressing them and causing the spring 4 to contract, resulting in a near-closed clamping effect. A handle 6 is coaxially slidably fitted onto the core column 1, and the handle 6 contains a pushing mechanism for moving the collar 5. This device constitutes the main body of the forceps, i.e., obstetric forceps.

[0026] Regarding the above example, those skilled in the art should understand that, when implementing the above technical solution, the clamp 2 has a window in the middle, which can reduce the pressure on the fetal head and prevent the obstetric forceps from slipping. The inner surface of the clamp 2 is concave, and the outer surface is convex, forming a curvature of the fetal head to adapt to the shape of the fetal head.

[0027] For the above example, those skilled in the art should know that when implementing the above technical solution, both the pliers 2 and the pliers 3 are made of stainless steel, which is convenient for cleaning and disinfection.

[0028] As a technical optimization of this utility model, each of the two clamping shanks 3 has a first slide rail 7 on its opposite side, and two second slide rails 8 are symmetrically arranged on the core column 1. The collar 5 has a sliding groove inside that can slide and match the two first slide rails 7 or the two second slide rails 8. The first slide rails 7 and the second slide rails 8 both serve to position the collar 5, facilitating the stable sliding movement of the collar 5. The collar 5 can be slidably removed from the core column 1.

[0029] As a technical optimization of this utility model, the pushing mechanism includes two slide rods 9. The core column 1 is provided with positioning grooves that slide and match the two slide rods 9, ensuring stable sliding of the corresponding slide rods 9. One end of each slide rod 9 can abut against one end of the collar 5, and the other end of each slide rod 9 is fixedly connected to an annular block 10. One end of the annular block 10 is coaxially rotatably connected to a rotating seat 11, and one end of the rotating seat 11 is coaxially fixed with a push rod 12. The handle 6 is provided with a cavity that matches the rotating seat 11, and the inner wall of the cavity is provided with an internal thread. The rotating seat 11 is provided with an external thread that matches the internal thread, and the rotating seat 11 is threadedly connected to the cavity. By rotating the push rod 12, the corresponding rotating seat 11 can be driven to rotate. The external thread of the rotating seat 11 can achieve threaded advance movement and has a self-locking effect. The advance of the rotating seat 11 can push the annular block 10 to move, and the movement of the annular block 10 can push the two slide rods 9 to move. The two slide rods 9 slide stably in their respective positioning grooves and push the collar 5 to move. Similarly, the rotating seat 11 can also be rotated and moved to be pulled out.

[0030] For the above example, those skilled in the art should know that when implementing the above technical solution, a rotating block is provided at the end of the push rod 12 away from the rotating seat 11 to facilitate the rotation of the push rod 12.

[0031] As a technical optimization of this utility model, each of the two sliding rods 9 has a locking block 13 fixed at one end abutting against the collar 5, and the collar 5 has a locking groove that matches the locking block 13. The locking block 13 enables the two sliding rods 9 and the collar 5 to be effectively connected.

[0032] As a technical optimization of this utility model, the inner side of the handle 6 is coaxially provided with an annular protrusion, and the outer side of the core post 1 is provided with a recessed groove that abuts against and matches the annular protrusion. After the handle 6 is slidably sleeved onto the core post 1, it can achieve a positioning effect by the annular protrusion abutting against the matching recessed groove. The handle 6 can also be slidably detached from the core post 1 as a whole.

[0033] As a technical optimization of this utility model, the handle 6 has two symmetrically arranged grooves in the middle. A first locking block 14 and a second locking block 15 are respectively engaged in the two grooves. Two cylindrical rods 16 are symmetrically fixed on the first locking block 14, and two insertion rods 17 are symmetrically fixed on the second locking block 15. Each cylindrical rod 16 has a slot, and the two insertion rods 17 can be inserted into the two slots respectively. The two cylindrical rods 16 slide horizontally through the handle 6 and the core post 1. After the handle 6 is fitted onto the core post 1, engaging the first locking block 14 allows the two cylindrical rods 16 to slide horizontally through the handle 6 and the core post 1. Then engaging the second locking block 15 allows the two insertion rods 17 to be inserted into the slots of the two cylindrical rods 16 respectively, thus achieving the positioning effect of the two cylindrical rods 16 and ultimately achieving the fixed connection operation between the handle 6 and the core post 1.

[0034] As a technical optimization of this utility model, the handle 6 is coaxially wrapped with a head anti-slip sleeve. The cross-section of the anti-slip sleeve is wavy. The handle 6 is easy to hold and facilitates forceful pulling when clamping the fetal head.

[0035] Regarding the above example, those skilled in the art should know that when implementing the above technical solution, the handle 6 and its components, as well as the components on the rotating seat 11, can be made of plastic and the whole can be replaced.

[0036] In this invention, the working principle of the device is as follows:

[0037] During tire head clamping, the push rod 12 is rotated, causing the corresponding rotating seat 11 to rotate. The external thread of the rotating seat 11 allows for threaded movement within the handle 6, and it also has a threaded self-locking effect. The rotating seat 11 then pushes the annular block 10 to move, which in turn pushes the two sliding rods 9 to move. The two sliding rods 9 slide stably within their respective positioning grooves, simultaneously pushing the collar 5 forward. By pushing the collar 5 forward, it slides onto the two clamping shanks 3 and compresses them, causing the spring 4 to contract and the two clamping keys 2 to achieve a near-closed operation, thus completing the tire head clamping effect. The rotating seat 11 maintains its threaded self-locking effect, effectively maintaining the clamping state without the need for manual holding. The external handle 6 is easy to hold and pull, effectively reducing the difficulty of operation and making the overall operation flexible and convenient.

[0038] Meanwhile, in subsequent operations, the rotating seat 11 can be rotated and moved out, and the handle 6 and its components can also be disassembled. That is, all of the above components can be disassembled for easy replacement after damage, or for thorough cleaning and disinfection after disassembly to prevent cross-infection.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
