具体实施方式 DETAILED DESCRIPTION

[0013] 本发明揭示了一种医用直线缝切器,如图1-图3所示,包括:可相互闭合或打开的上、下钳夹,相对设置在上、下钳夹远端的钉砧和钉仓,以及用于闭合上、下钳夹的闭合把手;所述钉仓表面沿器械轴线排列设有若干个钉孔,每个钉孔内均设置有相互抵接的推钉片和缝合钉。 [0013] The present invention discloses a medical linear seam cut, as shown in Fig. 1 to 3, comprising: mutually closed or open upper and lower jaw, opposite upper and lower jaw distal nail anvil and staple cartridge, and for the closing, at the closing jaws of the grip; push the staple sheet cartridge surface with a plurality of screw holes arranged along the instrument axis, each of the nail holes are provided in contact with each other and staples.

[0014] 所述上钳夹的中部设置有钳夹调节机构,所述调节机构包括前、后设置的两个偏心销及控制偏心销转动的旋转条11 ;所述偏心销分别为设置在旋转条11前端的锁紧销12,设置在旋转条11后端的支点销13。 [0014] the upper clamping jaw is provided with a central adjusting mechanism, the adjusting mechanism comprises a front, and two eccentric pin disposed eccentric control pin after rotating rotary strip 11; the eccentric pin disposed in rotation respectively Article 11 of the front end of the locking pin 12, 11 provided on the rear end of the rotary fulcrum pin strip 13.

[0015] 如图2所示,所述上钳夹的上表面开设有槽1,槽I内设置有旋转条11,所述旋转条11在槽内前、后移动。 [0015] As shown, the upper surface of the upper jaw of the creation of two grooved 1, the groove I set up a rotating bar 11, the rotating bar 11 before slot after moving. 所述旋转条11上开设有腰形槽21,所述腰形槽21内穿设有一用于固定上钳夹与旋转条11位置的固定销22。 The rotating bar opened a waist-shaped groove 21 on 11, the kidney-shaped groove 21 is provided through a fixed pin for securing the clamp strip 11 and the rotary position of 22. 所述旋转条11前、后移动的位移与腰形槽长度相当。 Article 11 of the rotation before and after the movement of displacement and kidney-shaped groove considerable length.

[0016] 两个偏心销均穿设于上钳夹的中部。 [0016] two eccentric pins are provided on the jaw through the middle. 所述旋转条11的前、后端下表面均设置有齿纹31,所述偏心销的中部外围设置有与旋转条11的齿纹31相啮合的齿条32,旋转条11的移动带动两个偏心销运动。 Article 11 of the rotating front, lower rear end surface is provided with tooth pattern 31, the central periphery of the eccentric pin is provided with a rotating rack teeth tattooed engagement Article 11 31 32, mobile drive two rotating strips 11 an eccentric pin movement.

[0017] 为了方便旋转条11前后移动,防止打滑,所述旋转条的上表面凸设有用于推动旋转条移动的波浪纹41。 [0017] In order to facilitate the rotation bar 11 moves back and forth to prevent slipping, the rotation of the upper surface of the projection is provided for urging the rotating bar 41 moving wave pattern.

[0018] 优选的,两个所述偏心销的偏心相位差为180°,结合图4所示,即当旋转条11移动到最前端和最后端时,则其中一个偏心销达到最高点34处,另一个偏心销达到最低点33处。 Eccentric phase [0018] Preferably, two of said eccentric pin is 180 °, in conjunction with FIG. 4, i.e., when the rotary bar 11 is moved to the foremost and rearmost end, then one of the highest point of the eccentric pin 34 Another eccentric pin 33 reached its lowest point. 这样就能使上、下钳夹之间的间隙间距变化幅度最大。 This would make the gap spacing of the biggest changes between the jaws under.

[0019] 下面结合附图简要说明下操作过程。 [0019] The following brief description of the drawings operating procedure.

[0020] 当待缝切组织被加入到上、下钳夹远端的钉砧和钉仓时,直线型缝切器闭合,此时,若组织的厚度较大,则调节钳夹调节机构,具体的通过拨动旋转条11,往前拨动,钉砧与钉仓的间隙变小;往后拨动,钉砧与钉仓的间隙变大。 [0020] The seam to be cut when the tissue is added to the upper and lower jaw distal end of the anvil and cartridge, linear slit cut is closed at this time, if the organization of large thickness, adjust the clamp adjustment mechanism, Specific rotation of Article 11 by the toggle, slide forward, anvil and cartridge gap is smaller; toggle back gap anvil and cartridge becomes large. 通过调节上钳夹前端进行夹紧和闭合的缓慢修整,使得一种型号的器械可以适应多种厚度的组织的缝合和切割,方便医生及医院。 By adjusting the front clamping jaw and closed slowly trimmed so that one model of instrument can be adapted to various thicknesses of tissue suturing and cutting, easy to doctors and hospitals. 为了使调节更符合预期要求,可以在缝切器的表面设有指示标志,指示标志可以为颜色指示或采用电子显示,用以显示上、下钳夹之间的间隙间距。 In order to make the adjustment more in line with expectations, may be provided with slits cut in the surface signs, signs may be indicative or color electronic display to display, the gap spacing between the lower jaw. [0021] 本发明尚有多种实施方式,凡采用等同变换或者等效变换而形成的所有技术方案,均落在本发明的保护范围之内。 [0021] there are various embodiments of the present invention, where the use of equivalents or equivalent transformation and the formation of all the technical solutions, all falling within the scope of the present invention.
