Abstract

The invention provides an operation sleeve tube and an operation tool for an arthroscopy. The operation sleeve tube comprises a sleeve and a top cover, the top cover is connected to the top of the sleeve, and the operation sleeve tub further comprises a sealing assembly; the sealing assembly comprises an upper sealing ring and at least one lower sealing ring, and the upper sealing ring and the lower sealing ring are arranged between the top cover and the sleeve in sequence in a stacked mode in sequence; a first sealing membrane is arranged in the ring of the upper sealing ring, the first sealing membrane is provided with a penetrating hole, and the first sealing membrane is in a shape which is arched downwards; the ring of each lower sealing ring is internally provided with a second sealing membrane, and the second sealing membrane is in a shape which is arched downwards and is at least halved. The operation sleeve tube is capable of maintaining a sealing state in two kinds of conditions of before an operating apparatus passes and after the operating apparatus passes, and is thus good in sealing performance.

Description

technical field

[0001] The invention relates to the field of surgical equipment, in particular to a surgical sleeve and an arthroscopic surgical tool. Background technique

[0002] In surgery, for example, in arthroscopic surgery, when using planers, burrs and other traumatic instruments, the repeated entry and exit of the instruments will easily lead to multiple tears in the joint capsule and increase the possibility of damage to important neurovascular tissues. . Especially for shoulder arthroscopic surgery, due to the rich shoulder muscles, there are many anatomical layers through which the body surface enters the joint cavity, and a slight change in direction will lead to other layers by mistake and the tool cannot be placed in the working position. Therefore, it is generally necessary to use a cannula to establish a working channel percutaneously, so that other arthroscopic surgical tools can enter the joint cavity through the channel.

[0003] The cannula plays a rol...
