Abstract
The invention discloses a single hole trocar, which comprises a cannula (1), wherein the cannula (1) consists of an outer tube (2) and an inner tube (3), an endoscope tube (6) is axially arranged in the inner tube (3), a position limiting clamp groove structure is arranged between the outer tube (2) and the inner tube (3), and comprises clamp heads (4) and clamp grooves (5), the clamp heads (4) are arranged on the outer circle surface of the inner tube (3) in an annular array way, and the clamp grooves (5) are in clearance clamping connection fit with the clamp heads (4) and are formed in the inner wall of the outer tube in an annular array way. The single hole trocar has the advantages that the structure is simple, the endoscope body position fixation can be conveniently realized, the labor is saved by an endoscope holder, and great space is reserved for other instruments, so that the surgery operation is convenient.
Description
Technical field
What the present invention relates to is armarium processing and manufacturing field, and what be specifically related to is a kind of single hole stamp card.
Background technology
Monotrysian type thoracoscopic operation in recent years at home and abroad thoracic surgery circle get the attention, development is rapidly.Single hole thoracoscope operation requirements shank and various apparatus enter thoracic cavity via same handle hole (being also observation port), because single operation bore dia is generally about 3-4cm, and shank can not rely on handle hole lower edge always, the person that makes to hold mirror relies on arm strength " to lift " all the time and shank, comparatively painstakingly.Shank also must remain in the periphery of handle hole as far as possible, larger space is left for other apparatuses carrying out operation technique, is in most cases positioned at handle hole top ideal.
Summary of the invention
The object of the invention is to provide a kind of single hole stamp card, and it can solve problem existing in background technology effectively.
In order to solve problem existing in background technology, it comprises sleeve pipe 1, this sleeve pipe 1 is made up of outer tube 2 and interior pipe 3, axially chamber mirror pipe 6 is provided with in described interior pipe 3, spacing notch is provided with between described outer tube 2 and interior pipe 3, described spacing notch comprises the draw-in groove 5 of the dop 4 of annular array on interior pipe 3 periphery and gap snap-fit engagement with it, and this draw-in groove 5 annular array is on the inwall of outer tube 2.
Described dop 4 is equilateral triangle structure, and described draw-in groove 5 is the equilateral triangle structure with dop 4 gap snap-fit engagement.
Described dop 4 is triangular structure of right angle, and its right-angle side is positioned on the periphery of pipe 3, and described draw-in groove 5 is the triangular structure of right angle with dop 4 gap snap-fit engagement.
Described dop 4 is semicircular structure, and described draw-in groove 5 is made up of the buckle 51 intermittently arranged, and described buckle 51 is the semicircular structure with dop 4 snap-fit engagement.
Owing to have employed above technical scheme, the present invention has following beneficial effect: structure had simply both facilitated shank position to fix, and person is laborsaving to hold mirror, reserves larger space can to again other apparatuses and be convenient to operation technique.
