Description

Laparoscope needle protection forceps

Technical Field

The utility model relates to a pair of laparoscopic surgery forceps, in particular to a pair of laparoscopic suture needle protection forceps.

Background

At present, in the latest surgical field, laparoscopic surgery replaces traditional open surgery, has the advantages of small wound, quick recovery of patients, short hospitalization time, few complications and the like, but how to simplify the operation steps of laparoscopic surgery and facilitate the operation is still the focus of research of medical workers today. Compared with the traditional open surgery, the laparoscopic surgery has more complex steps, higher requirements on the technical level of doctors and obvious dependence on surgical instruments.

Laparoscopic suturing procedures are a fundamental skill that a laparoscopic surgeon must master. At present, a plurality of laparoscopic operation instruments are clinically used, however, in laparoscopic surgery, surgeons often use needle holders to clamp needle tails and directly place the needle tails into abdominal cavities of patients through laparoscopic puncture outfits.

In the prior laparoscopic surgery, the needle placing operation causes the needle point to be in direct contact with the laparoscopic channel, which is very easy to cause the damage of the needle head, and even more likely to cause the separation of the needle head and a suture, fall into the abdominal cavity of a patient and be lost, thereby causing irreversible results, especially for young doctors with low experience. At present, no special needle head protection operating forceps aiming at avoiding the damage of a needle head of a sewing needle are clinically used.

Disclosure of Invention

An object of the utility model is to overcome the defect that exists among the prior art, provide a simple structure, avoid sewing needle and peritoneoscope passageway direct contact, avoid the syringe needle to damage, avoid sewing needle and suture to break away from peritoneoscope seam needle protection pincers.

The distance between the front end of the right forceps head and the forceps holder pin shaft is 5-10 mm.

And the inner side surfaces of the front part of the right forceps head and the front part of the left forceps head on the periphery of the needle placing groove are respectively provided with anti-skidding threads.

The utility model has the advantages that: the needle placing grooves are respectively formed on the inner side surfaces of the front part of the right forceps head and the front part of the left forceps head, so that an operator can put the whole needle into the needle placing groove during needle placing operation; the pull rod is pulled through the movable handle, the left forceps head and the right forceps head are opened or closed under the matching of the first movable connecting rod and the second movable connecting rod, after the suture needle is placed in the needle placing groove, the left forceps head and the right forceps head are closed, and then the suture needle is accurately sent into the abdominal cavity. The direct contact of the suture needle and the laparoscope channel is avoided, the damage of the needle head of the suture needle is avoided, and the separation of the suture needle and the suture is avoided. The distance from the front end of the right forceps head to the forceps holder pin shaft is 5-10mm, so that smooth passing of the suture needles with different sizes can be guaranteed, and a proper suture needle can be selected before the suture needle passes through the puncture outfit, so that the suture needle is prevented from being clamped in the puncture outfit due to improper size, and the surgical instrument is prevented from being damaged; meanwhile, the damage of the puncture outfit and the fracture of the sewing needle are avoided.

Detailed Description

Referring to fig. 1-3, the present invention includes a fixed jaw base 21, a movable jaw 22, a fixed handle 23 connected to the fixed jaw base 21, and a movable handle 24 connected to the movable jaw 22. The front end of the fixed clamp seat 21 is provided with a channel pipe 1. The movable handle 24 is hinged with the fixed handle 23.

The movable clamp 22 comprises a pull rod 2, a pull rod seat 3, a first movable connecting rod 7, a second movable connecting rod 8, a left clamp head 13 and a right clamp head 14. The main body of the pull rod 2 is positioned in the channel pipe 1, the rear end of the pull rod 2 is connected with the movable handle 24, the rear part of the pull rod seat 3 is cylindrical, open grooves 4 are respectively formed in two sides of the front part of the pull rod seat 3, an up-and-down through shaft hole 5 is formed in the front end of the pull rod seat 3, and the front end of the pull rod 2 is positioned in the pull rod seat 3 behind the shaft hole 5; the rear end of the first movable connecting rod 7 and the rear end of the second movable connecting rod 8 are respectively hinged with the front end of the pull rod 2 at the same pivot; the front end of the first movable connecting rod 7 is hinged with the rear end of the right tong head 14, and the front end of the second movable connecting rod 8 is hinged with the rear end of the left tong head 13; the right forceps head 14 and the left forceps head 13 are hinged through a forceps clip pin shaft 10, and two ends of the forceps clip pin shaft 10 are fixed in the shaft hole 5. The first movable connecting rod 7 and the second movable connecting rod 8 freely move in the opening groove 4, so that the pull rod 2 drives the left tong head 13 and the right tong head 14 to be opened or closed by pulling the first movable connecting rod 7 and the second movable connecting rod 8.
