Locking mechanism of abdominal operation forceps

Abstract

The invention relates to a locking mechanism of a pair of abdominal operation forceps, which is a part in the pair of abdominal operation forceps and is mainly suitable for locking a forceps rod when the pair of abdominal operation forceps is used in the abdominal operation of a human body. The locking mechanism comprises a rotary shaft, a clamping block and a locking positioning pin, and is characterized in that rotary shaft locking holes are formed in the rotary shaft; the central lines of the clamping block, the locking positioning pin and the rotary shaft locking holes are on the same axis and are perpendicular to the central line of the rotary shaft; the locking positioning pin is integrally connected with the clamping block; the rotary shaft locking holes are formed in the circumference of the rotary shaft; and the locking positioning pin is matched with the rotary shaft locking holes to achieve the locking effect. The locking mechanism is reasonable in structure design; the neck part of the forceps rod can be bent at an angle of 0-60 degrees to easily reach the required part of an operator; and the forceps rod can rotate at the angle of 360 degrees and can be locked in a corresponding position, so that the operator can conveniently control the forceps rod. Therefore, the locking mechanism is convenient and reliable to use in the operation.

Description

technical field [0001] The invention relates to a locking mechanism for abdominal surgical forceps, which is a part of the abdominal surgical forceps, belongs to medical equipment, and is mainly suitable for locking the forceps bar when the abdominal surgical forceps are operated in human abdominal surgery. Background technique [0002] Traditional abdominal surgical forceps include a rotating shaft, but there is no rotating shaft lock hole on the circumference of the rotating shaft, and there is no matching locking mechanism. Therefore, adjusting the rotating mechanism can only control the forward and backward movement, bending and 360° rotation of the forceps rod, and cannot make the The pliers rod is locked at the corresponding position while rotating 360°, so there are the following defects: during surgery, the operator controls the pliers head through the handle, and the rotation of the pliers head is realized by the rotation of the handle. When the pliers rod bends Fin...

Problems solved by technology

[0002]Traditional abdominal surgery forceps include a rotating shaft, but there is no rotating shaft lock hole on the circumference of the rotating shaft, and there is no matching locking mechanism, so the adjustment of the rotating mechanism can only Controlling the forward and backward movement, bending and 360° rotation of the pliers rod cannot make the pliers rod lock in the corresponding position while rotating 360°, thus there are the following defects: during surgery, the operator controls the pliers head through the handle, while the pliers head The rotation of the pliers is realized by the rotation of the handle. When the pliers rod is bent, the rotation of the pliers head in the human body is easy to touch the tissue of the human body, hindering the rotation of the pliers head. It can rotate 360° flexibly without any resistance, and there is easy relative sliding between the two, so the handle cannot control the pliers well.

[0003] Chinese Patent No. 2010102346538 discloses an invention patent named "Multifunctional Bendable Forceps for Laparoscopic Surgery", which includes interconnected forceps rods and handles Assemblies, the pliers rod includes an inner pull rod, a pliers sheath and a pliers core, and the handle assembly includes a handle and an adjustment rotation mechanism. The adjustment rotation mechanism can make the pliers rod move back and forth, bend and rotate 360°, but because there is no matching locking mechanism, It is not possible to lock the pliers rod at the corresponding position while rotating 360°, so it still has the above defects

[0004] Chinese Patent No. 002187582 discloses a utility model patent called "laparoscopic surgical forceps", which also includes interconnected forceps bars and handle assemblies, which can The pliers rod can be moved back and forth, but because there is no matching locking mechanism, it also cannot make the pliers rod rotate at 360° and lock in the corresponding position, so it still has the above defects
