Abstract
Description
Technical Field
[0001] This invention relates to the field of purse-string pliers technology, specifically a disposable linear cutting and sewing purse-string pliers. Background Technology
[0002] A purse-string forceps is a medical instrument used in gastrointestinal surgery, primarily for temporary purse-string closure during single-port laparoscopic surgery. Its core function is to clamp tissue and fix sutures through the jaws, thereby sealing the ends of ducts. Purse-string forceps are typically used in conjunction with a trocar and laparoscope. However, in actual surgery, due to the relative complexity of internal tissues, sometimes the trocar and laparoscope cannot work effectively with the purse-string forceps, making the procedure more challenging.
[0003] Preferred content To address the shortcomings of existing technologies, this invention provides a disposable linear cutting and suturing purse-string forceps, which solves the problems of abdominal puncture blockage and incompatibility between laparoscopy and purse-string forceps due to the relatively complex internal tissues of the body.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a disposable linear cutting and sewing purse-string clamp, comprising: A clamp housing, wherein a sleeve is connected to the clamp housing and a clamp head is provided on one side of the sleeve; The number of pliers is one pair and they are symmetrically distributed inside the pliers head; The clamps are a pair and are perpendicularly fixed to a pair of clamp handles on the same side.
[0005] In some embodiments, a direction adjustment rod is installed inside the clamp housing. The direction adjustment rod passes through the sleeve and is movably connected to a connecting tube at its top. The connecting tube is fixedly connected to one end of the clamp head and hinged to the sleeve at the other end. The clamp housing is provided with a direction adjustment handle, which is drivenly connected to the direction adjustment rod.
[0006] In some embodiments, a handle and a pliers head opening / closing trigger are mounted on the lower wall of the pliers housing, the pliers head opening / closing trigger cooperating with the pliers handle.
[0007] In some embodiments, the direction adjustment handle, located on the clamp housing, is configured as a knob handle.
[0008] In some embodiments, the sidewalls of the pair of clamps on opposite sides are provided with clamp teeth.
[0009] Beneficial effects: When using it, hold the handle and insert the cannula into the patient's body, then use the forceps opening and closing trigger to open the clamps, thereby creating a certain space in the patient's body, making it easier for instruments such as abdominal trocars and laparoscopes to be inserted into the patient's body.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0013] Please see Figure 1 The present invention provides a technical solution: a disposable straight cutting and suturing purse-string pliers, comprising: a pliers housing 1, the pliers housing 1 being connected to a sleeve 3, and a pliers head 6 being provided on one side of the sleeve 3; pliers handles 7, the number of pliers handles 7 being a pair and symmetrically distributed within the pliers head 6; and pliers clamps 8, the number of pliers clamps 8 being a pair and vertically fixed to a pair of pliers handles 7 on the same side.
[0014] The clamp shell 1, as the main support structure of the entire instrument, is integrally injection molded from medical-grade polymer material. It is sturdy and lightweight, and the surface is smoothed to improve grip comfort. One end of it is fixedly connected to the cannula 3 with a snap-fit, which is tight and not easy to fall off. The cannula 3 is a hollow cylindrical structure with a rounded end to avoid causing additional damage to human tissue during surgery.
[0015] In some embodiments, a direction adjustment rod 4 is installed inside the clamp housing 1. The direction adjustment rod 4 passes through the sleeve 3 and is movably connected to the top of the connecting tube 5. The connecting tube 5 is fixedly connected to one end of the clamp head 6 and the other end is hinged to the sleeve 3. The clamp housing 1 is provided with a direction adjustment handle 9, which is drivenly connected to the direction adjustment rod 4.
[0016] The direction adjustment rod 4 passes through the hollow cavity of the cannula 3, and its top is movably connected to the connecting tube 5 via a universal joint. The connecting tube 5 is also made of medical-grade stainless steel. One end is threadedly fixed to the bottom of the forceps head 6, ensuring a tight connection and facilitating assembly. The other end is hinged to the end of the cannula 3 via a hinge shaft, allowing for flexible rotation around the hinge shaft. Rotating the direction adjustment handle will rotate the direction adjustment rod 4, which in turn will drive the forceps head 6 to achieve multi-angle adjustment via the connecting tube 5, adapting to different operating angle requirements during surgery and improving the flexibility of surgical operations.
[0017] In some embodiments, a handle 2 and a pliers head opening / closing trigger 10 are mounted on the lower wall of the pliers housing 1, and the pliers head opening / closing trigger 10 cooperates with the pliers handle 7.
[0018] The handle 2 is integrally molded with the forceps housing 1 and adopts an ergonomic arc design that fits the palm when gripped, effectively reducing hand fatigue caused by prolonged surgical operations. The forceps head opening and closing trigger 10 is movably connected to the forceps housing 1 via a pin, with one end extending into the inside of the forceps housing 1 and cooperating with the forceps handle 7. When the trigger is pressed, the transmission structure drives the pair of forceps handles 7 to move relative to each other, thereby realizing the opening and closing of the forceps 8. The trigger has moderate elasticity, is smooth to press, and can automatically reset after being released, making it convenient for medical staff to quickly and accurately control the opening and closing state of the forceps.
[0019] In some embodiments, the direction adjustment handle 9 and the clamp housing 1 are configured as a knob handle.
[0020] The knob handle is made of medical-grade plastic with anti-slip textured surface for easy gripping and rotation by medical staff. The knob handle is coaxially fixedly connected to the direction adjustment rod 4. Rotating the knob allows for precise control of the rotation angle of the direction adjustment rod 4, thereby enabling fine-tuning of the angle of the forceps head 6. The size of the knob handle is adapted to human finger operation, and there is no jamming or loosening during rotation, ensuring the accuracy of angle adjustment.
[0021] In some embodiments, the sidewalls of a pair of clamps 8 are provided with clamp teeth.
[0022] The forceps teeth are precision milled, featuring evenly distributed serrations with smooth, rounded tips. This enhances the gripping force on the tissue, preventing slippage during clamping, while also avoiding damage from overly sharp teeth. The depth and spacing of the teeth are scientifically designed to accommodate different thicknesses of human tissue, ensuring stability and safety during clamping. This also facilitates easy release of the tissue post-surgery, minimizing secondary damage.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0024] Example: In use, hold the handle 2 and the clamp case 1, and insert the clamp head 6 into the patient's abdominal cavity through the sleeve 3. Then, rotate the direction adjustment handle 9 to adjust the direction of the clamp head 6, which is used to adjust the angle of the clamp handle 7 and clamp 8 in the abdominal cavity. Then, use the clamp head opening and closing trigger 10 to open the clamp handle 7 and clamp 8, creating a certain space in the patient's abdominal cavity, which facilitates the insertion of instruments such as abdominal trocars and laparoscopes into the patient's body.
