Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a multi-angle suturing needle holder for thoracoscopic and laparoscopic surgery. Background Art

[0002] The needle holder is an indispensable medical device during surgical suturing, and is mainly used to clamp and operate surgical instruments such as suture needles, blades, and guide wires.

[0003] The needle holder currently used in clinical practice clamps the suture needle by opening and closing the needle holder up and down. The front end of the needle holder is mostly in the shape of a straight structure. However, due to this straight structure, the suturing angle is relatively fixed when holding the needle, generally left-to-right or right-to-left suturing. During laparoscopic surgery, especially when fine suturing under single-port laparoscope requires adjustment of the suturing angle, the current conventional needle holder is more difficult to suturing, inflexible and inconvenient to use, and not conducive to operation. Long-term operation can easily lead to fatigue and accidental injuries, which increase unnecessary trauma and unnecessary risks to patients. There are blind spots in the two-dimensional image of the laparoscope, which cannot meet the current surgical suturing requirements for fine laparoscopic operations. Therefore, this straight needle holder is not suitable for fine suturing under laparoscopy.

[0004] In patent CN115153699A, the connecting rod of the device is driven by the push handle to move, driving the connecting part to rotate around the first pin axis, thereby separating the movable forceps and the fixed forceps. This device requires the push handle to be moved, which is not convenient for one-handed operation, and has a straight structure, which is not suitable for fine suturing under laparoscopy. Utility Model Content

[0005] The utility model provides a thoracoscopic and laparoscopic multi-angle suturing needle holder, which is intended to solve the technical problem that the existing device is difficult to operate with one hand during use, resulting in inconvenience in use.

[0010] Furthermore, the first needle holding clamp and the second needle holding clamp have a bending portion that forms an angle of 30-60° with the first needle holding rod and the second needle holding rod, thereby meeting the current surgical suturing requirements of laparoscopic operations.

[0011] Furthermore, the first handpiece and the second handpiece are provided with a clamping piece near the lower end of the annular portion for clamping and fixing the first handpiece and the second handpiece.

[0012] Preferably, the first needle holder and the second needle holder are provided with grooves on the lower sides of one end away from the first needle holder rod and the second needle holder rod, and the grooves are provided with criss-crossing fine teeth for better clamping the needle body.

[0013] The usage steps of the utility model are as follows: spread out the first handpiece and the second handpiece, the second handpiece drives the connecting rod mechanism, the connecting rod mechanism drives the first needle holding rod to move toward the first handpiece, the first handpiece drives the elastic member, thereby pulling the first needle holding clamp, because the lower end of the first needle holding clamp is hinged to the upper end of the second needle holding clamp, and its side is connected to the first needle holding rod, which can drive the first needle holding clamp to open, and clamping can be achieved by pinching the first handpiece and the second handpiece.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] 1. The utility model provides a thoracoscopic and laparoscopic multi-angle suturing needle holder. By setting a connecting rod mechanism, when the first handpiece and the second handpiece are opened, the second handpiece pulls the connecting rod mechanism, and the connecting rod mechanism drives the first needle holding rod to move toward the first handpiece. Since the lower end of the first needle holding clamp is hinged to the upper end of the second needle holding clamp, and its side is connected to the first needle holding rod, the first needle holding rod can drive the first needle holding clamp to open, and clamping can be achieved by pinching the first handpiece and the second handpiece. It is convenient and flexible to use, and can be operated with one hand to prevent harm to the patient during the operation.
