Description

外科用吻合器钉砧组件与器身之间的插拔结构 Surgical plug body structure between the anvil assembly and the stapling device

技术领域 FIELD

本实用新型属一种外科手术器具,具体涉及一种一次性使用的端-端吻合器钉砧组件与器身之间的弹性插拔结构。 The present invention belongs to a surgical instrument, particularly relates to a disposable end - plug structure between the ends of the elastic stapler anvil assembly and the body.

背景技术 Background technique

:消化道端-端吻合器是用于食道,胃,肠道等外科手术中管道断端与断端,管道断端与腔体侧面断口等管腔组织的吻合。 : Gastrointestinal to - end anastomosis is a surgical stapling tissue lumen of the esophagus, stomach, intestine ends and the duct ends, the cavity side surface of the pipe ends and the like fracture. 参见图1,其器身头部装有钉匣(3),并设有可与器身钉砧拉杆(2)插拔连接的钉砧(1),这种器具在手术过程中需要先将钉砧(1)埋入待吻合的一侧组织管腔荷包状端口,再将其与器身的钉砧拉杆(2)插接连接,通过转动尾翼旋钮调节钉砧拉杆(2)的进退,同时带动钉砧(1)运动,在临床手术中,将钉砧插入器身的钉砧拉杆后,有时需要拔下,这就需要向后拉动器身使其与前部的钉砧(1)相互脱离,所以插拔的难易程度会直接影响到操作的难易。 Referring to Figure 1, which is provided with a head body of the magazine (3), and may be provided with a plug body of the anvil rod (2) connected to the anvil (1), such a device requires a surgical procedure in the first the anvil (1) embedded in the side to be stapled tissue lumens purse-shaped port, then with the body of the anvil rod (2) plug connector, the anvil adjusting lever (2) forward and backward by turning the knob tail, at the same time drive the anvil (1) movement, in clinical surgery, the anvil is inserted into the body of the anvil rod, sometimes need to unplug, which need to pull back the anvil (1) the body so that the front part of the each other out, so the ease of plug will directly affect the ease of operation.

目前市场上同类产品的钉砧与器身的插拔连接结构是:将位于器身一侧的钉砧拉杆的锥形前端插入钉砧的中心连接杆,钉砧拉杆通过钉砧中心连接杆上设置的卡簧片从外部箍住锁紧连接杆,由于卡簧设置在钉砧一侧,插入锥头设在器身一侧;卡簧要单独加工,卡簧与钉砧的连接部位或者需外部开槽铆接,或者内部开槽后整体穿入固定,结构复杂,定位精度难以保证,加工工艺性不好,造成插拔操作上的困难;而且由于卡簧与钉砧部连接处的结构和空间限制,器身一侧的插入锥头部直径只能很细,刚性不好,容易变形。 Currently plug connection structure of the anvil and the body are similar products on the market: the tapered distal end side of the body is located in the anvil center rod of the anvil is inserted into the connecting rod, the anvil rod connected to the anvil center rod by snap-in tongues disposed externally hoop locking the connecting rod, since the circlip is provided at the side of the anvil, the insertion cone is provided on one side of the body; circlip to be processed separately, the connecting portion circlip or for an anvil crimping external grooved or slotted overall penetration after internal fixation, complex structure, difficult to ensure positioning accuracy, poor processing properties, resulting in difficulties to be unplugged; circlip and because the structure at the connection portion and the anvil space constraints, the diameter of the body is inserted into the side of the cone head can only be very small, not rigid, easily deformed.

发明内容 SUMMARY

本实用新型要解决的技术问题是克服上述不足,提供一种结构简单,易于加工,易于进行插拔操作的外科用吻合器钉砧组件与器身之间的插拔结构。 The present invention to solve the technical problem to overcome the above deficiencies, provide a simple, easy to process and surgical swap operation swap structures between the stapler and the anvil assembly in the body.

解决上述问题的技术方案是(参见实施例图):本实用新型设有钉钻(1)、位于吻合器器身一侧的钉砧拉杆(2),其特征在于:所述的钉砧拉杆(2)前部呈圆套筒(8),套筒内相对的内壁上分别设有与套筒壁为一体的、冲压成形的舌片状卡簧片(8a),卡簧片后端与套筒连为一体,卡簧片上设有向内凸起的凸台(8b),圆套筒外的吻合器器身内腔固定有可通过两平行壁箍住两卡簧片(8a)的方管(7),所述钉砧(1)的中心连接杆(4)端部呈尖锥体(6),尖锥体后部的杆体上设有环形凹槽(5)。 Solving the above problem is a technical solution (see Example figure): the present invention is provided with drill nail (1), located on one side of the body of stapler anvil rod (2), characterized in that: said anvil rod (2) the front portion of a circular sleeve (8), the inner sleeve are respectively provided integrally with the sleeve wall, the stamped and formed tongue-like snap-in tongues (8a) opposite the inner wall, and the rear end of the card reed sleeve as a single entity, the card is provided with an inwardly projecting tongue projections (8B), the body lumen stapler outer sleeve round hoop can be fixed to two snap-in tongues (8a) by two parallel side walls tube (7), said anvil (1) is connected to the central rod (4) form an end portion tapers (6), is provided with an annular groove (5) on the rear portion of the shaft tapers.

实际操作中,先使钉砧拉杆(2)从器身前端伸出,将钉砧的中心连接杆(4)插入钉砧拉杆前端圆套筒(8),中心连接杆的尖锥体(6)顶开卡簧片凸台(8b),凸台弹性扣住尖锥体后部的的凹槽(5),使钉砧中心连接杆与钉砧拉杆连接,当旋转尾翼旋扭使钉砧拉杆带动钉砧退回器身内时,由于圆套筒上的两卡簧片(8a)被器身内的方管(7)箍紧,失去向外撑开的空间,从而将钉砧尖锥体(6)与卡簧片(8a)相互锁紧,防止其在手术中脱开,在某些情况下需要拔出钉砧时,使钉砧拉杆伸出器身,脱离方管,即可拔出钉砧。 In practice, to enable the anvil rod (2) projecting from the front end of the body, a center of the anvil connecting rod (4) is inserted into the front end of the anvil rod circular sleeve (8), tapers center the connecting rod (6 ) to open the top snap-in tongue projections (8B), the boss of the elastic hold back the rear portion tapers recess (5), so that the anvil center rod and an anvil rod connected to the connection, when the rotational knob so that the anvil tail when the drive rod is retracted within the body of the anvil, since the two snap-in tongues (8a) on the circular sleeve is square tube (7) in tightening the body, loss of space distraction outwardly, thereby tapers anvil ( 6) with snap-in tongues (8a) interlocked to prevent disengagement thereof during surgery, in some cases need to pull the anvil so that the anvil rod extending the body, from the pipe, can be pulled anvil.

本实用新型结构简单,所采用的与圆套筒一体式的舌片状卡簧片结构,易于采用冲压成形的加工方法进行大批量生产,节约了制造成本,能够保证加工精度,故易于将钉砧的插拔锁紧力控制在易于操作的适宜程度,。 Simple structure of the present invention, employed the circular sleeve integral tongue-like snap-in tongue of the structure, easy processing method using press molding for mass production, saving the manufacturing cost, to ensure the machining accuracy, it is easy to nail plug locking force the anvil is controlled to a suitable extent that easy operation.

本实用新型适用于各类弯(直)外科用吻合器。 The present invention applies to all types of bending (straight) surgical stapler.
