Laparoscope operating forceps capable of allowing bending angle of forceps head to be locked

Abstract

The invention discloses a pair of laparoscope operating forceps capable of allowing locking the bending angle of a forceps head to be locked. The laparoscope operating forceps comprise a handheld part, a forceps nose, the forceps head and a control structure, wherein the handheld part comprises a drive toothed plate, a driven toothed piece and a handheld handle; the control structure is fixed on the handheld handle; the control structure is connected with the forceps head; the forceps head is connected with the forceps nose; a semi-circular part is formed at the front end of a core sleeve and is provided with convex teeth; two semi-circles are matched with each other; and the concave teeth are matched with the convex teeth. All the parts of the forceps are connected through tip shafts and hole buckles and are fixed through pipe sleeves, so that the laparoscope operating forceps is convenient to produce and assemble and the cost is reduced; the wrist channel pressure is reduced, fatigue is eliminated and the accuracy of the surgery is improved; the forceps rod head can serve as a disposable product; and the forceps rod head can also be disassembled into parts, and the parts are combined for use for many times after being cleaned and disinfected, so resources are saved.

Description

technical field [0001] The invention relates to the field of surgical forceps, in particular to a laparoscopic surgical forceps. Background technique [0002] The laparoscopic surgical forceps disclosed in the prior art are all designed with a straight head and no bendable angle, such as: Chinese patent numbers 200420022085.5, 200910096133.2, 200720191453.2, 200920115267.X. In many laparoscopic operations, due to deep abdominal lesions, its position is narrow, and the head of the general straight extension forceps cannot be bent, so it is entirely up to the doctor to twist the wrist joint to adjust and control the surgical forceps to perform the operation process. The traditional way of holding the pliers handle tends to make the wrist joint deviate, which will reduce the movement and distortion of the forearm cross-wrist muscles, thereby increasing the pressure on the carpal tunnel and causing wrist fatigue. [0003] The mutual connection mode of the movable joints of the ...

AI Technical Summary

Problems solved by technology

[0003] The active joints of the existing surgical forceps are all connected by tip shaft riveting connection structure, which has the disadvantage of complex structure, labor-intensive, time-consuming and high-cost riveting processing and assembly, and is not easy to disassemble and clean
