技术领域technical field
本发明涉及医疗器械领域，具体涉及一种宫颈抓钳。The invention relates to the field of medical instruments, in particular to a cervical grasping forceps.
背景技术Background technique
现有的宫颈抓钳由钳柄、钳头组成，钳柄之间通过销轴铰接，而钳头为一直的钳头，而宫颈抓钳主要用来夹持宫颈组织。现有的直钳头在夹持宫颈组织时需要经患者的阴道送入，而阴道为人体内具有一定弧度的自然通道，在送入后直钳头的过程中，术者需要在后方调整钳柄的位置以完成直钳头对宫颈组织的夹持，该直钳头的直线结构增加了手术的操作难度；同时由于宫颈组织较硬，现有的直钳头在夹持宫颈组织时极易发生摆动，造成手术的困难。Existing cervical pliers are composed of pliers handle and pliers head, the pliers handles are hinged by a pin, and the pliers head is a straight pliers head, and the cervical pliers are mainly used to clamp cervical tissue. The existing straight forceps head needs to be inserted through the patient’s vagina when clamping cervical tissue, and the vagina is a natural passage with a certain curvature in the human body. During the process of feeding the rear straight forceps head, the operator needs to adjust the forceps handle at the rear The position of the straight forceps is to complete the clamping of the cervical tissue by the straight forceps head. The linear structure of the straight forceps head increases the operation difficulty of the operation; at the same time, due to the hard cervical tissue, the existing straight forceps heads are very prone to occurrence of swing, causing difficulty in surgery.
发明内容Contents of the invention
本发明为了解决上述问题，设计了一种宫颈抓钳，该宫颈抓钳的钳头具有一定弧度以适应阴道的自然弧度，降低手术操作的难度；同时该抓钳的钳头上设有通长的相啮合的咬齿和咬齿槽以形成对宫颈组织更加稳定的夹持，防止手术中牵引宫颈组织时，宫颈组织发生摆动的问题，降低手术风险以及手术难度。In order to solve the above-mentioned problems, the present invention designs a cervical grasping forceps. The jaws of the cervical grasping forceps have a certain radian to adapt to the natural curvature of the vagina and reduce the difficulty of operation; The meshing teeth and grooves of the teeth form a more stable clamping of the cervical tissue, preventing the cervical tissue from swinging when the cervical tissue is pulled during the operation, and reducing the risk and difficulty of the operation.

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
参阅图1-3所示，一种宫颈抓钳，包括钳柄、销轴4和钳头5，钳柄、销轴和钳头选用不锈钢材料制成，钳柄包括左钳柄和右钳柄1，左钳柄和右钳柄1均由第一钳柄2和第二钳柄3组成，第一钳柄2的斜率小于第二钳柄3的斜率，该结构方式使得左钳柄的第一钳柄2和右钳柄1的第一钳柄2之间的距离增加，增加了力臂，进而可减小作用力的大小，以更小的力达到与直钳柄相同的夹持效果。钳头5包括左钳头6和右钳头7，所述的左钳头6和右钳头7同时弯向一侧并形成带有弧度的钳头5，左钳头和右钳头的弧度可与阴道的自然弧度保持接近，无需在钳柄后端调整其位置以适应阴道的弯曲弧度，降低操作的难度。左钳头6上沿其长度方向设有通长的卡条11，左钳头6的端部设有咬齿10，咬齿10向外伸出并指向右钳头7，咬齿10呈三棱锥状；所述的右钳头7上沿其长度方向开有通长的卡槽8，右钳头7的端部设有咬齿槽座12，咬齿槽座12向外伸出并指向左钳头6，咬齿槽座12上开有与咬齿10相啮合的咬齿槽9，宫颈组织被压紧与咬齿10和咬齿槽9之间，可防止钳头牵引宫颈组织时，宫颈组织发生摆动甚至脱出，提高手术的效率。As shown in Figure 1-3, a cervical grasping forceps includes a handle, a pin shaft 4 and a pincer head 5, the handle, pin shaft and pincer head are made of stainless steel, and the pincer handle includes a left pincer handle and a right pincer handle 1. Both the left handle and the right handle 1 are composed of the first handle 2 and the second handle 3. The slope of the first handle 2 is smaller than the slope of the second handle 3. This structure makes the second handle of the left handle The distance between the first pliers handle 2 and the first pliers handle 2 of the right pliers handle 1 is increased, which increases the force arm, thereby reducing the force and achieving the same clamping effect as the straight pliers handle with less force . The pincer 5 includes a left pincer 6 and a right pincer 7, and the left pincer 6 and the right pincer 7 are bent to one side at the same time and form a curved pincer 5, the arc of the left pincer and the right pincer It can be kept close to the natural curvature of the vagina, and there is no need to adjust its position at the rear end of the forceps handle to adapt to the curved curvature of the vagina, reducing the difficulty of operation. The left pincer head 6 is provided with a long clip bar 11 along its length direction, and the end of the left pincer head 6 is provided with teeth 10, and the teeth 10 protrude outwards and point to the right pincer head 7, and the teeth 10 are in a three-dimensional shape. Pyramid-shaped; the right pliers head 7 is provided with a long draw-in groove 8 along its length direction, and the end of the right pliers head 7 is provided with a tooth groove seat 12, and the tooth groove seat 12 protrudes outwards and points to The left pincer head 6, the biting groove seat 12 is provided with the biting groove 9 meshing with the biting teeth 10, and the cervical tissue is compressed between the biting teeth 10 and the biting groove 9, which can prevent the forceps head from pulling the cervical tissue , The cervical tissue swings or even prolapses, which improves the efficiency of the operation.
