技术领域technical field
本发明涉及医疗器械技术领域，特别涉及一种钛夹钳。The invention relates to the technical field of medical instruments, in particular to a titanium clamp.
背景技术Background technique
在大多数腹腔镜手术程序中，外科医生经常会使用钛夹钳将钛夹施加到血管以终止血液的流动。市场现有的钛夹钳是由一个包括U型环的施夹驱动组件的轴向移动来实现钳口的闭合，以使钛夹闭合血管。钛夹钳的钳口套接在U型环内部，且闭合状态钳口的外轮廓和U型环的内轮廓的横截面为大体相同的矩形，为保证钳口闭合与张开的往复运动，该U型环的矩形内轮廓与钳口闭合时的矩形外轮廓之间会存在一定的装配间隙，这种间隙会使钳口闭合时产生垂直于轴向方向的纵向错位，进而会导致钛夹不能有效成型，从而不能有效闭合血管。During most laparoscopic procedures, the surgeon will often use titanium clips to apply titanium clips to blood vessels to stop the flow of blood. The existing titanium clips on the market are closed by the axial movement of a clip application drive assembly including a U-shaped ring, so that the titanium clips close the blood vessel. The jaws of the titanium clamp are sleeved inside the U-shaped ring, and the cross-sections of the outer contour of the jaws in the closed state and the inner contour of the U-shaped ring are roughly the same rectangle. In order to ensure the reciprocating movement of the jaws closing and opening, There will be a certain assembly gap between the rectangular inner contour of the U-shaped ring and the rectangular outer contour when the jaws are closed. This gap will cause a longitudinal misalignment perpendicular to the axial direction when the jaws are closed, which will cause the titanium clip Cannot be formed effectively, so can not close blood vessel effectively.
因此，怎样避免钛夹钳的钳口在闭合时产生纵向错位，是本领域人员需要解决的问题。Therefore, how to avoid the longitudinal dislocation of the jaws of the titanium clamp when closing is a problem to be solved by those skilled in the art.

具体实施方式detailed description
本发明的核心是提供一种钛夹钳，该钛夹钳的钳口在闭合时不易产生错位。The core of the present invention is to provide a titanium pliers, the jaws of the titanium pliers are not easy to be dislocated when closed.
为了使本领域技术人员更好地理解本发明的技术方案，下面将结合附图和具体实施例对本发明作进一步的详细说明。In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
参见图1-图6，在本发明的一个实施例中，提供了一种钛夹钳，包括：钳口1、旋转钮3、击发手柄4、固定手柄5、下盖组件6。该下盖组件6包括：钳口固定板61、闭合件62、施夹推杆63、下盖64。钳口1包括位于近端的钳杆2，且还在远端包括与钳杆2连接的一对能够在隔开位置与接近位置之间活动的钳口构件11，且一对钳口构件11的外侧表面111和112中的至少一个为非平面结构。闭合件62位于施夹推杆63的远端并套接在钳口1外部，且可在施加推杆63的作用下沿该施加推杆63的轴向与钳口构件11产生相对运动，从而使一对钳口构件11接近与隔开。闭合件62与钳口构件11的外侧表面111和112接触的内侧表面621和622具有与钳口构件11的外侧表面111和112完全互补的结构，由此闭合件62的内部轮廓横截面与两个钳口构件11闭合时的外部轮廓横截面为大体吻合的非矩形形状，此时虽然存在一定的装配间隙，但由于非平面结构完全互补，从而抑制了一对钳口构件11闭合时沿垂直于钳杆2轴向方向的纵向位移。在手术中，由于钳口构件11的外侧表面为非平面结构，当钳口1初始张开时，握动击发手柄4，则施加推杆63促使闭合件62由近端向远端运动，逐渐使一对钳口构件11受到挤压力，在挤压力的作用下，一对钳口构件11逐渐闭合。由于闭合件62的内侧表面与钳口构件11的外侧表面为互补的非平面结构，这种互补的非平面结构使得在闭合件62的内侧表面与钳口构件11的外侧表面的接触处产生垂直于钳杆2轴向方向的纵向抑制力，这种抑制力使得钳口构件11在闭合时不易产生错位，从而使钛夹在闭合血管时能够良好地成型，从而保证手术的成功率。Referring to FIGS. 1-6 , in one embodiment of the present invention, a titanium clamp is provided, including: a jaw 1 , a rotary knob 3 , a firing handle 4 , a fixed handle 5 , and a lower cover assembly 6 . The lower cover assembly 6 includes: a jaw fixing plate 61 , a closing member 62 , a clamping push rod 63 , and a lower cover 64 . The jaw 1 includes a pincer bar 2 at the proximal end, and also includes a pair of jaw members 11 connected to the pincer bar 2 at the far end that can move between a spaced position and an approach position, and the pair of jaw members 11 At least one of the outer side surfaces 111 and 112 is a non-planar structure. The closing member 62 is located at the distal end of the clamping push rod 63 and is sleeved on the outside of the jaw 1, and can move relative to the jaw member 11 along the axial direction of the applying push rod 63 under the action of the applying push rod 63, thereby The pair of jaw members 11 are approached and spaced apart. The inner side surfaces 621 and 622 of the closure member 62 in contact with the outer side surfaces 111 and 112 of the jaw member 11 have a configuration that is completely complementary to the outer side surfaces 111 and 112 of the jaw member 11, whereby the inner profile cross-section of the closure member 62 is compatible with both sides. The outer profile cross-section of the two jaw members 11 when they are closed is a substantially coincident non-rectangular shape. Although there is a certain assembly gap at this time, the non-planar structure is completely complementary, thereby inhibiting the pair of jaw members 11 from closing along the vertical direction. The longitudinal displacement in the axial direction of the clamp rod 2. During the operation, since the outer surface of the jaw member 11 is a non-planar structure, when the jaw 1 is initially opened, the firing handle 4 is held, and the push rod 63 is applied to force the closure member 62 to move from the proximal end to the distal end, gradually making a The pair of jaw members 11 are subjected to extrusion force, and under the action of the extrusion force, the pair of jaw members 11 are gradually closed. Due to the complementary non-planar structure of the inner surface of the closure member 62 and the outer surface of the jaw member 11, this complementary non-planar structure causes a vertical contact between the inner surface of the closure member 62 and the outer surface of the jaw member 11. Due to the longitudinal restraining force in the axial direction of the forceps rod 2, this restraining force makes it difficult for the jaw member 11 to be dislocated when closing, so that the titanium clip can be well formed when closing the blood vessel, thereby ensuring the success rate of the operation.
优选地，一对钳口构件11中至少一个的外侧表面为凸面，则闭合件62与钳口构件11的凸面接触的相应内侧表面为凹面，且凹面轮廓横截面的纵向高度沿横向从内向外逐渐减小。握动击发手柄4，闭合件62在施加推杆63的作用下由近端向远端运动，钳口构件11在闭合件62的挤压下，逐渐由隔开位置向接近位置靠拢，直至完全闭合，由于闭合件62与钳口构件11的侧部接触面在结构上完全互补，而闭合件62又是一体式刚性结构，所以当闭合件62的内侧凹面与钳口构件的外侧凸面完全吻合时，在吻合接触面之间产生的纵向抑制力的抑制下必然使一对钳口构件11不易产生垂直于钳杆2轴向的纵向位移，从而保证钳口1闭合时不易错位，保障了钛夹的良好成型。Preferably, the outer surface of at least one of the pair of jaw members 11 is convex, and the corresponding inner surface of the closure member 62 in contact with the convex surface of the jaw member 11 is concave, and the longitudinal height of the concave profile cross section is from the inside to the outside along the transverse direction. slowing shrieking. Hold the firing handle 4, the closing member 62 moves from the proximal end to the distal end under the action of the push rod 63, and the jaw member 11 gradually moves from the spaced position to the approaching position under the extrusion of the closing member 62 until it is completely closed. Closed, because the closure 62 and the side contact surface of the jaw member 11 are completely complementary in structure, and the closure 62 is a one-piece rigid structure, so when the inner concave surface of the closure 62 is completely matched with the outer convex surface of the jaw member At the same time, under the suppression of the longitudinal restraining force generated between the anastomotic contact surfaces, the pair of jaw members 11 will inevitably make it difficult to produce longitudinal displacement perpendicular to the axial direction of the pincer rod 2, so as to ensure that the jaws 1 are not easily dislocated when they are closed, and the titanium Good shaping of the clip.
进一步优选地，一对钳口构件11的外侧表面111和112均为凸面，则与一对钳口构件11的凸面结构接触的闭合件62的内侧表面621和622均为凹面，且凹面轮廓横截面的纵向高度沿横向从内向外逐渐减小。当两个钳口构件11的外侧表面111和112为对称且相同的凸面结构时效果最佳。例如，一对钳口构件11的外侧表面111和112的凸面结构的横截面的形状可以是锥形或半圆形或半椭圆形或半枣胡形或梯形或三角形或锯齿形，等等。图7-图10示出了一对钳口构件11的两个外侧表面111和112分别为对称的锥形、等腰梯形、直角梯形和圆弧形的实施例。Further preferably, the outer surfaces 111 and 112 of the pair of jaw members 11 are both convex, and the inner surfaces 621 and 622 of the closure member 62 that are in contact with the convex structure of the pair of jaw members 11 are both concave, and the concave profile is transverse The longitudinal height of the section gradually decreases from the inside to the outside along the transverse direction. It works best when the outside surfaces 111 and 112 of the two jaw members 11 are of symmetrical and identical convex configuration. For example, the cross-sectional shape of the convex structure of the outer side surfaces 111 and 112 of the pair of jaw members 11 may be conical, semicircular, semielliptical, semi-date, trapezoidal, triangular, zigzag, etc. 7-10 show embodiments in which the two outer surfaces 111 and 112 of a pair of jaw members 11 are symmetrically tapered, isosceles trapezoidal, right-angled trapezoidal and arcuate, respectively.
此外，一对钳口构件11的两个凸出的外侧表面111和112也可以是不同的结构。例如，两个钳口构件11的两个外侧表面111和112为不同的凸面结构，如可以分别为锥形和半圆形等等不同的凸面结构。In addition, the two convex outer surfaces 111 and 112 of the pair of jaw members 11 may also be of different structures. For example, the two outer surfaces 111 and 112 of the two jaw members 11 have different convex structures, such as different convex structures such as cone and semicircle respectively.
更进一步地，凸面结构沿钳口构件11的外侧表面延伸的长度大体等于闭合件62与钳口构件11相对运动的距离，由此保证在钳口1与闭合件62相对运动的过程中两个钳口构件11的动作一致，不易发生纵向位移而导致闭合时错位，且组装方便。Furthermore, the length of the convex structure extending along the outer surface of the jaw member 11 is substantially equal to the distance of the relative movement of the closure member 62 and the jaw member 11, thus ensuring that the two jaws 1 and the closure member 62 move relatively. The action of the jaw member 11 is consistent, the longitudinal displacement is not easy to cause dislocation during closing, and the assembly is convenient.
又进一步地，凸面结构沿钳口构件11的外侧表面一直延伸到钳杆2的外侧表面，且凸面沿钳口1轴向的长度大于闭合件62与钳口构件11相对运动的距离。凸面沿钳口构件11的外侧表面延伸的长度大于闭合件62与钳口构件11相对运动的距离，能够更好地保证钳口构件11相对于闭合件62运动时动作一致，不易发生纵向位移而导致闭合时错位，且组装方便。Still further, the convex structure extends along the outer surface of the jaw member 11 to the outer surface of the pliers rod 2 , and the length of the convex surface along the axial direction of the jaw 1 is greater than the relative movement distance between the closure member 62 and the jaw member 11 . The length of the convex surface extending along the outer surface of the jaw member 11 is greater than the relative movement distance between the closure member 62 and the jaw member 11, which can better ensure that the movement of the jaw member 11 is consistent when moving relative to the closure member 62, and the longitudinal displacement is not easy to occur. Causes misalignment when closed, and is easy to assemble.
根据本发明的又一实施例，一对钳口构件11中至少一个的外侧表面为凹面，则闭合件62与钳口构件11的凹面接触的相应内侧表面为凸面，且该凸面轮廓横截面的纵向高度沿横向从内向外逐渐增大。两个钳口构件11的外侧表面111和112为对称且相同的凹面结构时效果最佳。一对钳口构件11的凹面结构的横截面的形状可以是锥形或半圆形或半椭圆形或半枣胡形或梯形或三角形或锯齿形，等等。According to yet another embodiment of the present invention, at least one of the outer surfaces of the pair of jaw members 11 is concave, the corresponding inner surface of the closure member 62 in contact with the concave surface of the jaw members 11 is convex, and the profile cross-section of the convex surface The vertical height gradually increases from the inside to the outside along the horizontal direction. It works best when the outside surfaces 111 and 112 of the two jaw members 11 are symmetrical and identically concave. The shape of the cross-section of the concave structure of the pair of jaw members 11 can be conical, semicircular, semielliptical, semi-date, trapezoidal, triangular, zigzag, etc.
凹面沿钳口构件11的外侧表面一直延伸到钳杆2的外侧表面，且凹面沿钳口1轴向的长度大于或大体等于闭合件62与钳口构件11相对运动的距离，由此，保证了钳口构件11相对于闭合件62运动时动作一致，不易发生纵向位移而导致闭合时错位，且组装方便。The concave surface extends along the outer surface of the jaw member 11 to the outer surface of the pliers rod 2, and the length of the concave surface along the axial direction of the jaw 1 is greater than or substantially equal to the relative movement distance between the closure member 62 and the jaw member 11, thereby ensuring This ensures that the movement of the jaw member 11 is consistent when moving relative to the closing member 62, and the longitudinal displacement is not easy to cause misalignment during closing, and the assembly is convenient.
