Embodiment Construction

[0028] in such as figure 1 In the case of the illustrated embodiment, a cannula 1 produced according to the invention comprises a body part 2 having a first end 3 and a second end 4 and containing a sleeve 5 connected to the body part 2 The second end 4 of the body part 2 is such that there is a channel 6 extending from the first end 3 of the body part 2 to an end 7 facing away from the body part 2 (hereinafter referred to as "sleeve end 7").

[0029] A seal 8 is provided in the body part 2 to divide the channel into a first section 9 extending from the seal 8 to the first end 3 of the body part 2 and a second section 10 extending from the seal 8 extends to the sleeve end 7.

[0030] The cannula 1 can receive an endoscope (not shown here), which is guided from the first end 3 into the channel 6 . For this purpose, a guide 11 is provided in the body part 2 in the region of the first end 3 . In addition, after setting the guide part 11, a fixing assembly 12 is also provided, ...

Abstract

A cannula comprising: a body portion having a first end and a second end; a sleeve connected to the second end of the body portion; a channel extending from the first end of the body portion to an end of the sleeve facing away from the body portion, for receiving instruments; and a seal mounted in the body portion and having a resilient seal having a hollow cylindrical wall dividing the channel into a first segment and a second segment, the first segment extending from the seal Extending to a first end of the main body portion, a second section extends from the seal to an end of the sleeve facing away from the main body portion, the elastic seal closes and isolates the first and second sections from each other when the instrument is properly inserted into the channel, wherein the sealing The member includes a shank secured in the body portion and gripping a portion of the hollow cylindrical wall of the resilient seal such that the resilient seal is secured in the shank.

Description

technical field [0001] The invention relates to a sleeve device. Background technique [0002] Cannulae are often used in surgical procedures where at least a portion of the cannula is placed within the subject and the main body portion is exposed. In this way, the channel enables the introduction of appropriate instruments into the subject to perform the planned surgical procedure. Specifically, the endoscope can also be introduced through the channel. [0003] In such applications, fluids (eg, irrigation or other bodily fluids) from the second section of the cannula cannot enter the first section, protecting the instrument from damage (eg, an endoscope). A seal is therefore provided, realized as a hollow cylindrical sealing ring, glued into the body part. However, it is not possible to achieve a permanently fixed seal by this, which would lead to accidental leakage. Contents of the invention [0004] The present invention relates to a cannula comprising: a body porti...
