Problems solved by technology

[0003] However, due to the small opening during the operation, the angle and position of the opening will change, and the range of movement of the surgical forceps in the human body is small, so the doctor is often required to cooperate with the movement angle of the surgical forceps, which causes the doctor's hands to be in a twisted position for a long time. Angle, the doctor's hand is prone to numbness, which will affect the safety of the operation and the health of the doctor

Embodiment 1

[0112] A universal minimally invasive surgical forceps with a locking mechanism of the present invention includes a handle housing 12 , a surgical forceps head, a handle opening and closing member 4 hinged with the handle housing 12 , and a handle opening and closing member 4 adapted to The handle mandrel 11 also includes a steering mechanism and a locking mechanism;

[0113] One end of the handle housing 12 is provided with a limiting cavity 1201, the outer wall of the limiting cavity 1201 is provided with a limiting stage 1205, one side of the limiting cavity 1201 is provided with an opening, and the opening extends inwardly with a limiting collar 1202, the limiting cavity The other side of the body is provided with a limit baffle 1203, the limit baffle 1203 is provided with a mandrel limit hole 1204, the handle mandrel 11 passes through the mandrel limit hole 1204 on the limit baffle 1203 and the handle opening and closing part 4 matches;

[0114] The steering mechanism is...

Embodiment 2

[0140] The rest is the same as the solution in Embodiment 1. A pin 9014 is fixedly arranged in the ball joint relinquishment cavity 9011, and a limit groove 2021 that matches the pin 9014 is provided in the circumferential direction of the ball joint 202; the ball joint relocation cavity 9011 is in the A ball joint limiting hole 9013 is provided on the cavity wall corresponding to the maximum diameter of the cavity;

[0141] When the ball joint forceps head is not blocked by the blocking member, under the action of external force, the ball joint 202 can rotate and reciprocate along the circumferential direction where the limiting groove 2021 is located. At this time, the limiting groove 2021 reciprocates relative to the pin 9014 Sliding; the ball joint 202 can also perform rotational reciprocation relative to the central axis of the pin 9014 or the maximum diameter of the cavity. The function of the pin is to limit the rotational and reciprocating movement of the ball joint 20...

Embodiment 3

[0144] The rest is consistent with the solution in Embodiment 2, the pin 9014 is tangent to the limiting groove 2021, or the pin 9014 is stuck in the limiting groove 2021;

[0145] In the present invention, the pin 9014 is limited in the limiting groove 2021 through the cooperation of the primary ball joint fixing member 1 , the ball joint 202 and the assembly of the connecting pipe 901 .

Abstract

The invention discloses universal minimally invasive operating forceps with a locking mechanism, which comprise a handle shell (12), an operating forceps head matched with the handle shell (12), a handle opening and closing piece (4) hinged with the handle shell (12), a handle core rod (11) matched with the handle opening and closing piece (4), a steering mechanism and the locking mechanism. According to the universal operating forceps, the straight rod type operating forceps in the prior art are changed into the operating forceps capable of performing universal movement through structural improvement, the problem that a doctor encounters certain angles of operation in an operation can be solved through mutual cooperation of the steering mechanism and the locking mechanism, and the modes can be conveniently switched back and forth.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a universal minimally invasive surgical forceps with a locking mechanism. 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] However, due to the small opening in the operation, the angle and position of the opening will change, and the movement range of the surgical forceps in the human body is small, and the doctor often needs to cooperate with the angle of the surgical forceps movement, which causes the doctor's hand to be in a distorted position for a long time. From an angle, the doctor's hand is prone to numbness, which will affect the safety of the operation and the health of the doctor. SUMMARY OF THE INVENTION [0004] In view of this, it is necessary to provide a universal minimally invasive s...
