Definitions

  • the utility model relates to a surgical instrument, in particular to a flushing suction device.
  • Flushing the aspirator is an important tool used in laparoscopic and open surgery. It is used to provide irrigation solution to the surgical site to clear the field of view of the bleeding site, and to attract blood and other liquids and tissue fragments from the surgical site by vacuum suction; in particular, it can be identified and accurately before using RF energy or electrocoagulation cutting. Position the bleeding site.
  • the flushing aspirator is typically used in conjunction with a 5 mm or 10 mm trocar sleeve or trocar of a CO 2 pneumothorax to maintain inflation of the body cavity to create a surgical space for delivery of the instrument into the body cavity under operation.
  • Conventional flushing aspirator devices include single lumen tubes (most common 5 mm in diameter, but sometimes 10 mm) and typically one or more valves characterized as "horns" that can be attached to attract or rinse.
  • Disposable instruments are usually made of plastic, and the recirculating instruments are made of detachable stainless steel and cleaned and disinfected before and after use in different patients and surgical procedures. Valves need to be disassembled for effective cleaning and cleaning. However, it is difficult to clean due to valve and pipe geometry. Therefore, one-time use is currently used.
  • Flushing aspirator mainly uses a single lumen tube to flush and attract through a common chamber. Attracting and flushing a common lumen also causes the "dirty" fluid (such as contaminated blood or blood clots and opaque liquids or solids) that has just been sucked back to be returned to the patient. In vivo, this makes the exploration of bleeding sites more difficult. And because the incomplete removal of liquid from the tubing typically results in potentially contaminated liquid remaining in the tubing and back to the surgical site. This is often referred to as the "drip" of the surgical site and creates an additional risk of infection at the surgical site. There are flushing suctions in the prior art via two different chambers, one for suction and the other for flushing.
  • the liquid stream When used for rinsing, the liquid stream typically has a low flow rate and flows slowly from the pipe, so prior art uses a disposable pump or pressurized container (e.g., nitrogen pressurization) to add pressure to the rinsing supply, which adds additional cost. And the risk of using this flushing aspirator. Although it provides a better flushing effect, the high flow rate consumes a large amount of flushing flow and requires frequent suction of excess liquid. To control the total energy in the liquid flow, there must be a relatively low pressure, and excessive pressure can cause unnecessary damage to the surgical part. Therefore, there is no flushing suction device with good flushing effect and convenient use in the prior art.

Abstract

一种冲洗吸引器，包括：三腔管（1）、歧管（2）、两根软管（5，6）、控制单元（3，4，12）和双排管；三腔管（1）包括常压冲洗腔（7）、高压冲洗腔（8）和一个吸引腔（9），吸引腔（9）的横截面积大于常压冲洗腔（7）的横截面积，常压冲洗腔（7）的横截面积大于高压冲洗腔（8）的横截面积；三腔管（1）与歧管（2）连接，歧管（2）将三腔管（1）的常压冲洗腔（7）、高压冲洗腔（8）与一根软管（5）连接，将三腔管（1）的吸引腔（9）与另一根软管（6）连接；两根软管（5，6）内气体或液体的流动速度受控制单元（3，4，12）的控制，两根软管（5，6）与双排管连接。在手术中根据需要既能提供常压冲洗又能提供高压冲洗，而且吸引腔（9）的口径大，不易堵塞，吸引和冲洗的气体流或液体流完全独立，冲洗效果好，使用方便。

Description

一种冲洗吸引器 技术领域
本实用新型涉及外科器械，尤其涉及一种冲洗吸引器。
背景技术
冲洗吸引器是在腹腔镜手术和开腹手术中使用的重要工具。用于给手术部位提供冲洗液，以清理出血部位的视野，以及利用真空吸引，从手术部位吸引血液和其它液体和组织碎片；特别的是还可以在使用RF能量或电凝切割之前识别和准确定位出血部位。冲洗吸引器通常采用与CO2气腹机的5mm或10mm的穿刺器套管或穿刺器结合使用，以维持体腔的充气，以产生手术操作空间，方便传递器械进入接受手术的体腔内。传统的冲洗吸引器装置包括单腔管(最常见外直径为5mm，但有时为10mm)和通常一个或多个表征为“喇叭”的阀门，可以将管连接以吸引或冲洗。一次性的器械通常由塑料制成，循环使用的器械则由可拆卸的不锈钢制成，并在不同患者和手术项目使用前后进行清洁和消毒。阀门需要拆卸以进行有效的清洁和净化。但是因阀门和管道几何形状而使其难以清洁。所以，目前多使用一次性的。
冲洗吸引器主要使用单腔管通过公共腔进行冲洗和吸引，吸引和冲洗共用一个内腔还导致刚刚吸回的“脏”液体(如被污染的血液或血块等不透明液体或固体)回流到患者体内，这使得出血部位探查更加困难。并且因为管道中液体清除不彻底通常会导致潜在污染的液体存留在管道中并且返回到手术部位。这通常称作手术部位的“滴注”，会在手术端产生额外的感染危险。现有技术中有经由两个不同的腔的冲洗吸引器，一个用于吸引，另一个用于冲洗。当用于冲洗时，液体流通常流速低且自管道缓慢流动，所以现有技术采用一次性泵或加压容器(例如氮气加压)为冲洗的供应增加压力，这种做法增加了额外的成本和使用该冲洗吸引器的风险。虽然能提供更好的冲洗效果，但是高流速消耗大量冲洗流，需要频繁吸引多余液体。要控制液体流中的总能量，必须有相对低的压力，过大的压力会对手术部分产生不必要的伤害。所以，现有技术中没有一种冲洗效果好且使用方便的冲洗吸引器。
