Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 5, the rotationally adjustable medical grasper of this embodiment includes a handle 1, a connecting member 2, a sleeve 3, a locking member 4, a spring 5, a mounting seat 6, an inner core rod 7, and an outer sheath 8, and the handle 1 is connected to the inner core rod 7 through the connecting member 2. The sleeve 3 is connected with the mounting seat 6, the locking piece 4 and the spring 5 are arranged in the sleeve 3, one end of the spring 5 abuts against the mounting seat 6, and the other end of the spring abuts against the locking piece 4. Be equipped with spline portion 31 in the sleeve pipe 3, locking piece 4 corresponds the setting with spline portion 31, overcoat 8 is connected with locking piece 4, and inner core pole 7 wears to establish in overcoat 8, and the end of inner core pole 7 is equipped with head 9, head and 8 pivot connections of overcoat. In the technical scheme, the connecting assembly 2 drives the inner core rod 7 to move through the operating handle 1, so that the head 9 can be opened or closed. Through pulling overcoat 8 for locking piece 4 disengages with spline portion 31, can make overcoat 8 can rotate the angle of adjusting head 9, after rotatory target in place, release overcoat 8, the restoring force of spring promotes locking piece and spline portion 31 joint, realizes the location. Through the technical scheme, the angle of the head can be adjusted when minimally invasive surgery is performed, and a user can conveniently and smoothly operate the minimally invasive surgery.
In this embodiment, the connection assembly 2 includes a connection member 21, a connection seat 22 and a positioning block 23, the positioning block 23 is disposed in the connection seat 22, the positioning block 23 is connected to the inner core rod 7, and the connection member 21 is connected to the connection seat 22. Through the technical scheme, the handle 1 can drive the connecting piece 21, and the positioning block 23 drives the inner core rod 7 to move, so that the front end head 9 is opened or closed.
In this embodiment, the connecting member 21 has the bent portion 211, so that the connecting member 21 forms a plurality of gap portions 212 arranged at intervals, and the toughness of the connecting member itself is utilized to reduce the tensile force of the positioning pin 91 of the head portion 9, so that the positioning pin is more durable.
In this embodiment, the spline portion 31 is provided with a key groove 311, the key groove 311 is disposed around the spline portion, and the locking member 4 has a protrusion 42, and the protrusion 42 is disposed corresponding to the key groove 311.
In this embodiment, the inner wall of the sleeve 3 is provided with a guide groove 32, the mounting seat 6 is provided with a limiting portion 61, and the limiting portion 61 is disposed in the guide groove 32. Through above-mentioned technical scheme, can avoid mount pad 6 and sleeve pipe to break away from.
