Description

Linear type suturing and cutting device for surgical operation

Technical Field

The invention relates to the technical field of medical suturing and cutting devices, in particular to a linear suturing and cutting device for surgical operations.

Background

In the prior art, the linear cutting stapler with an inter-bridge structure, which is applied under the application number of '201510550045.0', comprises a nail pusher, a nail bin seat, a cutting knife and a sliding knife rail; the nail pushing device is matched with the nail bin to assist in forming nails, the nail bin is arranged on the nail bin seat, and the cutting knife is arranged on the sliding knife rail and is positioned at the rear middle shaft position of the nail bin. When the cutting knife enters the nail bin along the forward movement of the sliding knife rail, a sliding knife groove is reserved at the position of the middle shaft of the nail bin. The cutting knife slides forwards on the sliding knife rail, enters the nail bin sliding knife groove and reaches the front end to expose the cutting part for cutting and sewing. The linear cutting stapler with the bridge structure can synchronously complete suture and cutting, can realize front end cutting and two-side suture, and has a linear anastomotic stoma, namely, the cutting suture part only occurs at the front end of the acting tissue in the bridge structure, and the rear end of the bridge structure is kept complete.

However, the method still has the obvious defects in the using process: 1. the nail bin of the linear suturing and cutting device can be replaced for multiple use, and when the linear suturing and cutting device is clinically used, tissues are often required to be sutured and cut for multiple times, so that the nail bin is required to be replaced for multiple times during operation, and under the condition that the nail bin is not placed, the excitation button in the linear suturing and cutting device can be pushed forwards at will, and then the cutter can be pushed out, so that the serious result that only cutting is carried out but suturing is not carried out can be caused; 2. because some careless doctors or inexperienced doctors can carry out the next operation under the condition that the shot nail bin is not replaced, the medical accidents can be caused, namely, the excision is carried out but no suture is carried out, the excitation button in the device can push out the cutter for many times, and great potential safety hazards exist.

The working principle is as follows: the use of the device can be analyzed according to the following states, firstly, the device is in a state that the nail bin 3 is not installed, at the moment, thesliding plate 20 is in a state of being ejected outwards by thespring 21, thepawl 30 is in a state of limiting theratchet wheel 31, so that theratchet wheel 31 can only rotate clockwise at the moment, therefore, if thecutter 12 is tried to be pushed outwards, the adjustingrod 13 and thefirst rack 17 are necessarily driven, thefirst rack 17 is necessarily driven to drive the transmission gear III 35 when moving, the transmission gear III 35 needs to drive the transmission shaft II 32 to rotate through the transmission gear II 33, the transmission shaft II 32 needs to drive theratchet wheel 31 to rotate, at the moment, the rotation of theratchet wheel 31 needs to be anticlockwise rotated, but under the action of thepawl 30 and thepawl limiting rod 301, theratchet wheel 31 cannot rotate anticlockwise, namely, the pushing-out of thecutter 12 is locked in a non-return way, and the situation that thecutter 12 is not put into the nail bin 3 is effectively avoided, The serious consequence of cutting without sewing.

Secondly, after the nail bin 3 is installed, theinstallation rod 38 on the positioning portion 9 is clamped and embedded in thegroove 18, thesecond protrusion 39 is located on the inner side of thefirst protrusion 19 at the moment, locking is achieved, theinstallation rod 38 pushes thesliding rod 22 through thesliding plate 20, thesliding rod 22 drives thesecond rack 24 to move, thesecond rack 24 drives thefirst transmission gear 25 to rotate when moving, thefirst transmission gear 25 drives therotating wheel 28 to rotate through thefirst transmission shaft 26, the rotatingwheel 28 drives thepawl 30 to rotate, locking of theratchet wheel 31 is released, and as can be known by combining the above description, thecutter 12 at the moment can be normally pushed out for use, special operation is not needed to release locking, limitation of thecutter 12 is automatically released in the process of installing the nail bin 3, and the operation is more convenient.

After the nail bin is used, the adjustingrod 13 needs to be driven to move through the adjusting button 6, thecutter 12 is further driven to be recovered, the adjustingrod 43 needs to be moved until the clamping and embedding rod is clamped and embedded in the clamping and bucklingframe plate 41, at the moment, thefourth protrusion 431 is located on the inner side of thethird protrusion 411, locking is achieved, when the adjustingrod 13 is locked and limited, thecutter 12 is also locked and limited, secondary triggering is prevented, thecutter 12 is prevented from being easily thrown out or pushed out, and misoperation is prevented.

Finally, after the new nail bin 3 is installed, theinstallation rod 38 on the positioning part 9 is clamped and embedded in thegroove 18, at this time, on one hand, thepawl 30 rotates to unlock theratchet wheel 31, so that the first heavy restriction is released, and on the other hand, theslide rod 22 drives theextension rod 40 to move, so that theclamping frame plate 41 is far away from the clamping and embeddingrod 43, so that the second heavy restriction is released, the double restriction is more safe, the one-key release is simpler, and the use is convenient.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
