Detailed ways

The technical solutions of the present invention will be further elaborated below with reference to the embodiments and the accompanying drawings.

Example 1

In the following description, when we install the staple cartridge rotation control device of the endoscopic stapler on the endoscopic stapler, the end close to the hand operation is the proximal end, and the end far from the hand operation is the distal end; The right end in the figure is the proximal end, and the left end is the distal end.

Referring to FIGS. 1 to 6 , this embodiment provides a staple cartridge rotation control device for an endoscopic stapler, including a fixed housing 1 , a steering connecting rod 8 , a circumferential energy storage member 9 and a rotation pushing assembly 10 ; the The proximal end of the steering connecting rod 8 is arranged in the fixed housing 1 , the upper end of the fixed housing 1 is provided with an operation through hole 11 , and the circumferential energy storage member 9 is circumferentially fastened to the operation through hole. 11 on the inner wall, and the circumferential energy storage member 9 circumferentially defines the rotary push assembly 10; The pusher assembly 10 is connected to the proximal end of the steering connecting rod 8; when the circumferential energy storage member 9 moves circumferentially, the energy is released so as to decrease in length in the radial direction. The distal end of the steering connecting rod 8 acts on the staple cartridge assembly of the endoscopic stapler to realize the rotation of the staple cartridge assembly; when the staple cartridge assembly needs to be rotated, the rotating push assembly 10 is rotated, because the circumferential storage The energy member 9 limits the rotary push assembly 10 in the circumferential direction, then when the rotary push assembly 10 provides a driving force in the circumferential direction, the circumferential energy storage member 9 releases energy, which will reduce the length of the circumferential energy storage member 9 in the radial direction. Because the circumferential energy storage member 9 is fastened on the inner wall of the operation through hole 11 opened at the upper end of the fixed housing 1 in the circumferential direction, when the radial length of the circumferential energy storage member 9 is reduced, the circumferential energy storage member 9 will no longer be fastened. On the inner wall of the operating through hole 11, the rotary push assembly 10 drives the steering connecting rod 8 to act on the rotation of the staple cartridge assembly. Since the circumferential energy storage member 9 releases its own energy through the circumferential braking, it is It shrinks itself in the radial direction, and the contracted circumferential energy storage member shrinks radially, and the restriction on its radial direction will decrease or disappear, so that the circumferential energy storage member 9 can be driven by a certain power. It is no longer restricted by the circumferential direction of the inner wall of the operating through hole 11, so the rotation of the circumferential energy storage member 9 can be continuous, so that the staple cartridge assembly can be rotated and positioned to any desired angle within the range of 45 degrees left and right, without There will be only a few fixed angle restrictions, which brings greater operability to the doctor's surgical operation and improves the scope of instrument operation. The circumferential energy storage member 9 here refers to having a certain amount of energy in the circumferential direction, and this energy can be utilized or released, so that the entire circumferential energy storage member 9 can produce a certain deformation as a whole, and this This kind of deformation can achieve the above operation purpose of the device. For example, the circumferential energy storage member 9 may be a member that can be compressed in the circumferential direction or a deformable elastic member, or a torsion bar rotating shaft structure device formed by a plurality of rotating shaft arms that can vary in length in the radial direction, and the like. For example, the elastic member can be a radially compressible elastic spherical member disposed in the operating through hole 11. When it needs to be rotated, the elastic spherical member can be radially contracted to achieve the operation purpose. Of course, a pair of matching can be set here. For other fittings of the elastic spherical member, the elastic spherical member may undergo changes such as stretching in the vertical direction in the operating through hole 11 when the elastic spherical member is radially contracted, and fittings for the above deformation may be provided.

In this embodiment, preferably, the circumferential energy storage member 9 is a torsion spring 12 , the torsion spring 12 can generate elastic force in the circumferential direction, and the outer wall of the torsion spring 12 passes through the inner wall of the operating through hole 11 .

The torsion spring 12 is an elastic accumulator. The torsion spring 12 is arranged on the inner wall of the operating through hole 11 in an interference fit, and the rotary push assembly 10 is activated to give a driving force to the torsion spring 12 in the circumferential direction. The torsion spring 12 When being stretched in the circumferential direction, the circumferentially stretched torsion spring 12 shrinks in the radial direction, and the length in the radial direction is reduced, so that when the rotary push assembly 10 rotates, it can drive the staple cartridge assembly to rotate through the steering connecting rod 8. At any angle required by the user, when the angle of rotation is reached, the rotation of the rotary push assembly 10 is stopped, so that the rotary push assembly 10 no longer stretches the torsion spring 12 in the circumferential direction. 12 will automatically return to its original state, and it will interfere with the inner wall of the operating through hole 11 again, so that the nail cartridge assembly will be positioned at the angle of rotation, realizing self-locking, thereby preventing the nail cartridge assembly from rotating by itself, which not only expands the size of the instrument. The operating range also guarantees the safety of use.

This design structure is relatively uncomplicated, and it is safe and reliable on the basis of realizing the above-mentioned functions. The rotating first end 16 and the rotating second end 17 provided on the part of the rotating member 13 in the operating through hole 11 are respectively fitted to the initial end 14 of the twisted wire of the torsion spring 12 and the circumferential direction of the terminal end 15 of the twisted wire of the torsion spring 12 One side of the torsion spring 12 can be stretched circumferentially. Here, the initial end 14 of the torsion wire of the torsion spring 12 and the terminal end 15 of the torsion wire of the torsion spring 12 can be preferably set to be limited to the first rotating end 16 and the second rotating end. The position between the ends 17 extending along the inner wall of the operating through hole 11 is set in this way, so that the staple cartridge assembly can be rotated in different directions no matter which direction the operation is rotated in.

The control track 21 controls the circumferential movement track of the rotating member 13 . When the rotating member 13 needs to be rotated, the control shaft 19 can be used to rotate it. Because the control board 20 is set as a circular plate body and is covered on the torsion spring 12 of the operating through hole 11, this can effectively prevent the torsion spring 12. The up-and-down movement in the operation through hole 11 that may occur during circumferential stretching and rotation improves the stability and safety of the operation; set the control track 21, and the control track 21 can be a circular arc-shaped short board, and the circular arc The two ends of the short plate form a rotating first end 16 and a rotating second end 17, then the arc-shaped short plate just fits on the inner side of the torsion spring 12, and the rotating first end 16 and the rotating second end 17 terminate.
