Description

一种可冲洗吸引和快速更换导管的腹腔钳A peritoneal forceps capable of flushing, suctioning and quickly changing catheters

技术领域Technical field

本发明涉及一种医疗器械,尤其涉及一种适用于人体腹腔手术中的剥离、夹持、冲洗、吸引等操作的腹腔钳。The invention relates to a medical instrument, and in particular to an abdominal forceps suitable for operations such as stripping, clamping, flushing, and suctioning in human abdominal surgery.

背景技术Background technique

传统的腹腔手术钳,包括相互连接的钳杆和手柄组件,钳杆包括内拉杆、钳鞘管和钳芯,内拉杆和钳芯分别与钳鞘管连接,手柄组件包括手柄和带有转轴且能旋转的调节旋转机构,手术时,操作者控制手柄的旋转是使钳头张合,实现剥离、夹持功能。但是,在整个手术的过程中常常伴随着频繁的组织冲洗和废液抽吸操作,因此医生在手术过程中需要在冲洗器械,吸引器械与腹腔钳之间来回切换,医疗器械的切换使配合难度增加,更换器械也会浪费一定的时间;更重要的,冲洗液有一定几率不能马上被抽吸而流到非手术部位,引起组织感染;更麻烦的是在微创手术中,频繁的更换器械会为手术带来极大的不便。Traditional abdominal surgical forceps include an interconnected forceps rod and a handle assembly. The forceps rod includes an inner pull rod, a forceps sheath tube and a forceps core. The inner pull rod and forceps core are respectively connected to the forceps sheath tube. The handle assembly includes a handle and a rotating shaft. The rotating adjustment mechanism can be rotated. During surgery, the operator controls the rotation of the handle to open and close the clamp heads to achieve peeling and clamping functions. However, the entire operation is often accompanied by frequent tissue flushing and waste fluid aspiration operations. Therefore, the doctor needs to switch back and forth between flushing instruments, suction instruments and abdominal forceps during the operation. The switching of medical instruments makes coordination difficult. In addition, changing instruments will also waste a certain amount of time; more importantly, there is a certain probability that the irrigation fluid cannot be sucked immediately and flows to non-surgical parts, causing tissue infection; what is even more troublesome is that in minimally invasive surgery, frequent instrument changes It will bring great inconvenience to the operation.

中国专利号 2011100865671 公开了一种名称为“腹腔镜手术内置式吸引器”的发明专利,尽管它可以同时对手术部位进行组织冲洗和抽吸废液,但它是将吸引器在手术时始终放在腹腔内,以减少更换器械所带来的弊端 ;所以其不可避免地存在以下缺点 :由于使用时,医生必须用钳子夹住持吸引头吸除渗血和渗液,所以医生很难做到快速冲洗,快速抽吸,这就有可能造成渗血和渗液抽吸不及时而感染非手术部位。Chinese Patent No. 2011100865671 discloses an invention patent called "Built-in Aspirator for Laparoscopic Surgery". Although it can flush tissue and aspirate waste fluid at the surgical site at the same time, it requires that the aspirator be always placed during surgery. In the abdominal cavity to reduce the disadvantages caused by changing instruments; therefore, it inevitably has the following disadvantages: When using it, the doctor must use pliers to hold the suction head to suck out the bleeding and exudate, so it is difficult for the doctor to do it Rapid flushing and rapid aspiration may cause bleeding and untimely aspiration of exudate, which may lead to infection of non-surgical sites.

中国专利号 002187582 公开了一种名称为“腹腔镜手术钳” 的实用新型专利,它也包括相互连接的钳杆和手柄组件,其能使钳杆前后移动,从而使钳头张合。但是也存在明显缺点:手术时需要频繁更换冲洗吸引器,浪费时间又存在感染风险。Chinese Patent No. 002187582 discloses a utility model patent named "Laparoscopic Surgical Forceps", which also includes a forceps rod and a handle assembly connected to each other, which can move the forceps rod back and forth to open and close the forceps heads. However, there are also obvious disadvantages: the irrigation and suction device needs to be replaced frequently during surgery, which wastes time and risks infection.

控制冲洗、吸液速度操作:参考图4,推滚动压轮18沿滑槽26下滑,挤压冲洗导管15,从而得到减小流量的效果,滚动压轮的行程在手柄盖24开槽限定,参考图1所示。Control the flushing and suction speed operations: Refer to Figure 4, push the rolling pressure wheel 18 down the chute 26, and squeeze the flushing conduit 15, thereby achieving the effect of reducing the flow rate. The stroke of the rolling pressure wheel is limited by the groove in the handle cover 24. Refer to Figure 1.

更换导管操作:参考图6,手动旋松螺栓9,此状态下导管与锁紧块12为间隙配合,所以可从钳头方向抽离导管。同理,新导管亦从钳杆定位套头7方向装配,导管定位后,手动旋紧螺栓,使导管与锁紧块连接。Conduit replacement operation: refer to Figure 6, manually loosen the bolt 9. In this state, the conduit and the locking block 12 have a clearance fit, so the conduit can be pulled out from the direction of the clamp head. In the same way, the new conduit is also assembled from the direction of clamp rod positioning sleeve 7. After the conduit is positioned, manually tighten the bolt to connect the conduit to the locking block.

滑动凸台10可使吸引导管14、冲洗导管15进行伸缩,在需要时伸出对目标组织进行冲洗和废液吸引。The sliding boss 10 can make the suction conduit 14 and the irrigation conduit 15 expand and contract, and when necessary, extend out to flush the target tissue and aspirate waste fluid.

本发明的内推杆和钳头部分可拆卸消毒,冲洗和吸引的导管可快速更换。The inner push rod and clamp head part of the present invention are detachable and sterilizable, and the catheter for irrigation and suction can be quickly replaced.

以上所揭露的仅为本发明一种较佳实施例而已,当然不能以此来限定本发明之权利范围,因此依本发明权利要求所作的等同变化,仍属本发明所涵盖的范围。What is disclosed above is only a preferred embodiment of the present invention.
