Problems solved by technology

[0003] Minimally invasive surgical tools such as electronic soft mirrors need to use flexible joints, so how to properly and reasonably adjust the flexible joints during surgery has become an urgent problem to be solved. There are many flexible joint adjustment devices in the prior art, but the structural design in the prior art It is unreasonable, inconvenient to adjust and cannot be used in conjunction with other structures of electronic soft mirrors such as surgical forceps. The cooperation with surgical forceps will affect the operation of the rest of the surgical forceps and affect the use. It is urgent to provide a flexible joint universal adjustment mechanism
[0004] Due to the small opening in minimally invasive surgery, the angle and position of the opening will change, and the range of movement of the surgical forceps in the human body is small, which often requires the doctor to cooperate with the movement angle of the surgical forceps, which causes the doctor's hands to be in a certain twist for a long time The angle of the doctor's hand is prone to numbness, which will affect the safety of the operation and the health of the doctor. It is urgent to provide a well-designed adjustment handle

Embodiment 1

[0116] A flexible joint universal adjustment mechanism of the present invention includes a rocker 13, a ball joint 14, a buckle 15 and a fixing member 18;

[0117] The rocker 13 includes a spherical body giving way cavity 1301 and an adjusting rod 1302 fixedly connected with the spherical body giving way cavity 1301; a cylindrical limiting boss 1303 is symmetrically arranged on the inner wall of the spherical body giving way cavity 1301 in the radial direction;

[0118] The ball joint 14 includes a connecting plate 1401 and a spherical body 1402 fixedly connected with the connecting plate 1401. The spherical body 1402 is provided with a limiting groove 1403 that matches the cylindrical limiting boss 1303 in the circumferential direction;

[0119] The ball joint 14 is arranged in the spherical body relinquishment cavity 1301, and the limit is formed by the mutual cooperation of the cylindrical limit boss 1303 and the limit groove 1403;

[0120] The buckle 15 includes a bottom r...

Embodiment 2

[0126] The rest is the same as the solution in Embodiment 1. There are two limit grooves 1403, and the two limit grooves 1403 are limit grooves on the same outer peripheral line of the spherical body 1402;

Embodiment 3

[0128] The rest is the same as the solution in Embodiment 1 or 2. The inner wall of the spherical body relinquishment cavity 1301 is provided with a clamping groove 1304, the bottom ring 1501 of the buckle 15 is provided with a clamping structure 1502, and the clamping groove 1304 and the clamping structure 1502 are provided. Matchingly, the buckle 15 forms a detachable fixed connection with the spherical body relocation cavity 1301 through the clamping groove 1304 and the clamping structure 1502 .

Abstract

The invention discloses a flexible joint universal adjusting mechanism which comprises a rocker (13), a ball joint (14), a buckle (15) and a fixing piece (18). The adjusting handle comprises the flexible joint universal adjusting mechanism and further comprises the axis movement mechanism and the rotary movement mechanism, the flexible joint universal adjusting mechanism and the adjusting handle are both applied to minimally invasive surgery, the flexible joint universal adjusting mechanism can meet adjustment driving, and the adjusting handle is reasonable in structural design, convenient to operate and high in practicability. The axis reciprocating motion of the core rod, the rotation of the adjusting handle and the universal rotation of the flexible joint are separated, the purpose that the motion direction of the flexible joint is always unique is achieved, and the use requirements of doctors can be met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a flexible joint universal adjustment mechanism and an adjustment handle. Background technique [0002] Minimally invasive surgery has been widely promoted due to its small opening, less trauma and quick recovery, and is widely used in surgery in various departments at this stage. [0003] Minimally invasive surgical tools, such as electronic flexible endoscopes, need to use flexible joints, so how to properly and reasonably adjust the flexible joints during surgery has become an urgent problem to be solved. There are many adjustment devices for flexible joints in the prior art, but the structural design of the prior art It is unreasonable, inconvenient to adjust, and cannot be used in conjunction with other structures of the electronic flexible mirror, such as surgical forceps. The cooperation with the surgical forceps will affect the operation of the remaining parts of ...
