Problems solved by technology
Due to the limitation of the patient's epidermal incision in laparoscopic surgery, the commercially available slender needle holder with only clamping action can only adjust the rolling posture of the curved suture needle through the autorotation action
At present, doctors commonly use auxiliary adjustments through other instruments, or adjust their posture by re-clamping the arc-shaped suture needle. This method prolongs the time for adjusting the posture of the arc-shaped suture needle and suturing operation, and increases the difficulty and cost of the operation. risk

The invention discloses a needle holder capable of adjusting the three-dimensional postures of an arc-shaped suture needle, and the needle holder comprises a clamping jaw mechanism, an adjusting runner mechanism, a support rod mechanism, a clamping jaw driving mechanism and an adjusting runner driving mechanism, wherein the adjusting runner mechanism is arranged in the clamping jaw mechanism, the clamping jaw mechanism is arranged on the front end of the support rod mechanism, the clamping jaw driving mechanism is arranged on the rear end of the support rod mechanism, and the runner driving mechanism is arranged in the clamping jaw driving mechanism. The clamping jaw mechanism of the needle holder can clamp the rear end of the arc-shaped suture needle, and the adjusting runner mechanism can rub the arc-shaped suture needle and adjusts the pitching and deflection postures thereof. When holding and operating the needle holder, a doctor can directly adjust the horizontal rolling postures of the clamped arc-shaped suture needle. The needle holder can adjust the three-dimensional postures of the arc-shaped suture needle in an endoscopic surgery, so that the doctor can conveniently use the arc-shaped suture needle to suture.
Description
Technical field [0001] The invention relates to a medical device, in particular to a needle holder with adjustable arc suture needle three-dimensional posture for endoscopic surgery. Background technique [0002] In surgery, especially in endoscopic surgery, suture is a common treatment method used by doctors. The current suture method adopts a needle holder that can only adjust the rolling posture of the suture needle to hold the arc suture needle, and suture the tissues and organs of the patient under the endoscopic operation. [0003] The arc-shaped suture needle used in endoscopic surgery has a special shape. The doctor clamps the back end of the arc-shaped needle when suturing, and needs to align the front-end arc-shaped needle tip of the suture needle with the object to be sutured in a proper posture. Due to the limitation of the patient's epidermal incision during laparoscopic surgery, the commercially available slender needle holder with only clamping action can only adjus...
