Detailed description of the invention is used for further illustrating but is not limited to the present invention below, below embodiment be only one of the present invention preferably embodiment.
Detailed description of the invention
Please refer to Fig. 1 to Figure 14, the invention provides a kind of perforator with automatic sewing function, comprising: nail bin 1, comprise primary importance and the second position; Nail forming blocks 2, is connected with nail bin 1; Slide block 3, comprises the 3rd position and the 4th position; First flexible member 4, applies First Driving Force to nail bin 1; Second flexible member 5, applies the second driving force to slide block 3; Puncturing lever 6, is resisted against the first side of puncturing lever 6 along first direction when nail bin 1 is positioned at primary importance, be resisted against the second side of puncturing lever 6 when slide block 3 is positioned at the 3rd position along second direction; Puncturing lever 6 to extract to nail bin during the first firing position 1 first at the move under influence of the first flexible member 4 to the second position, when puncturing lever 6 is extracted completely slide block 3 the move under influence of the second flexible member 5 to the 4th position to drive nail forming blocks 2 by suturing nail 7 molding in nail bin 1.Preferably, first direction is orthogonal with second direction.
During use, please refer to Fig. 8 and Fig. 9, when puncturing lever 6 runs through nail bin 1, nail forming blocks 2 is resisted against on puncturing lever 6 under the effect of the first flexible member 4, and meanwhile, slide block 3 is resisted against on puncturing lever 6 under the effect of the second flexible member 5.Please refer to Figure 10 and Figure 11, when puncturing lever 6 is upwards extracted to illustrated first firing position, puncturing lever 6 has vacateed mobile space for following closely forming blocks 2, so, under the effect of the first flexible member 4, nail forming blocks 2 is released by primary importance and is covered the below (namely arriving the second position) of puncturing lever 6, but, because the position of slide block 3 is higher than the position of following closely forming blocks 2, therefore, slide block 3 is still subject to the obstruction of puncturing lever 6 and keeps original state constant (being namely still positioned at the 3rd position).Please refer to Figure 12 and Figure 13, after puncturing lever 6 is upwards extracted by continuation completely, puncturing lever 6 vacates mobile space for slide block 3, so, under the effect of the second flexible member 5, slide block 3 is moved by the direction of the 3rd position to nail forming blocks 2, and nail forming blocks 2 is depressed to the direction of nail bin 1, until the 4th position, be pushed out aftershaping to make the suturing nail 7 in nail bin 1, the tissue on otch both sides is drawn in and sews up, reach automatic sewing object.
Visible, owing to have employed technique scheme, after Minimally Invasive Surgery completes, while being extracted from intraperitoneal by puncturing lever 6, the automatic sewing of otch can be realized, thus reduce operation operation, save operating time, have the advantages that structure is simple, easy to operate, cost is low.
Preferably, nail forming blocks 2 is formed with first and presses down inclined-plane 8, slide block 3 is formed and applies second of downforce to nail forming blocks 2 press down inclined-plane 9 for pressing down inclined-plane by first.Arrange because nail forming blocks 2 and slide block 3 stagger at vertical direction, therefore, when slide block 3 moves to the direction of following closely forming blocks 2, it second presses down first of inclined-plane 9 and nail forming blocks 2 and presses down inclined-plane 8 and contact, along with the further movement of slide block 3, nail forming blocks 2 is moved down, thus the suturing nail 7 be placed in nail bin 1 is released and molding.
Preferably, the perforator of band automatic sewing function also comprises to nail block 10, and that supports nail block 10 inserts supporting in nail block installing hole bottom nail bin 1 at least partially actively.Preferably, nail block 10 is supported L-shaped.Please refer to Figure 12, during molding, two tack claws of suturing nail 7 are embraced to nail block 10.Please refer to Figure 14, when after suturing nail 7 molding, operator move supporting nail block 10 to the direction away from nail bin 1, thus shift out supporting nail block 10 from the suturing nail 7 formed.
Preferably, nail bin 1 is provided with the depressed part of U-shaped towards the side supporting nail block 10, supports the corresponding depressed part of nail block 10 and arranges.Utilize depressed part, certain installing space can be provided for supporting nail block 10, thus reduce volume of the present invention.
Preferably, in one embodiment, the first flexible member 4 and support nail block 10 and be all arranged on the same side of nail bin 1.When the first flexible member 4 promote nail bin 1 move time, also promote support nail block 10 move together with nail bin 1.
Preferably, the both sides supporting nail block 10 are respectively arranged with first flexible member 4.Preferably, nail bin 1 is T-shaped, each side has one for fixing the blind hole of the first flexible member 4 at nail bin 1.Adopt two the first flexible members 4, nail bin 1 can be promoted more reposefully, make it move more smooth and easy, stuck problem can not occur.
Preferably, the number of the second flexible member 5 is one.Obviously, multiple second flexible member 5 also can be set as required, all belong to the equivalent substitute mode of this patent, within the protection domain of this patent.
Preferably, perforator with automatic sewing function also comprises housing 11, housing 11 inside is formed with installing space, housing 11 is provided with the through hole 12 run through, nail bin 1, nail forming blocks 2, slide block 3, first flexible member 4 and the second flexible member 5 are all arranged in installing space, and puncturing lever 6 is through through hole.Especially, the inwall of the installing space of housing 11 is provided with the blind hole for fixing the first flexible member 4 and the second flexible member 5.During installation, one end of the first flexible member 4 and the second flexible member 5 is placed in the blind hole of housing 11, and the other end can be placed in the corresponding blind hole on nail bin 1 or slide block 3, fixing with what realize the first flexible member 4 and the second flexible member 5.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
