Description
Technical field
The present invention relates to operation auxiliary devices, and it is thick in stomach wall minimal incision sites to establish bore safely in laparoscopic surgery
Big sleeve channel.
Background technique
Laparoscopic surgery is that miniature incision is implemented on stomach wall, and stomach wall miniature incision is in contraction closed form in its natural state
State, in order to establish big channel in stomach wall, it is sometimes desirable to be inserted into inferior epigastric vessels by force using coarse outer tube, due to skin,
Subcutaneous fat and the rich elastic reaction of abdominal wall muscle, therefore inferior epigastric vessels can be expanded by force in a short time, that is, exist
Stomach wall establishes the smooth big channel communicated with abdominal cavity, so as to the bulk tissue or organ of laparoscopic resection and coarse
The safe and smooth discrepancy abdominal cavity of surgical instrument.So expand the coarse channel of foundation by force, although bore it is coarse ensured it is enough
Clear space, but the postoperative natural elasticity due to abdominal wall tissue is replied, and notch is still small as before.
However, since outer tube caliber is coarse, it is sometimes desirable to the tiny inner sleeve of caliber gradually excessively and be converted into be suitable for
It is placed in conventional laparoscopy surgical instrument, therefore needs after internal and external casing fitting while using again, usually in the axis of internal and external casing
The heart is placed in puncture awl and punctures merging abdominal cavity jointly.But outer tube is coarse, spikes through in abdominal skin small notch thick and solid
Abdominal wall tissue when it is very laborious, it is even more impossible to active rotation be in puncture front end inner sleeve, press puncture awl when rotary sleeve
Pipe is also especially laborious, and when outer tube rotation, does not also follow rotation in the inner sleeve for puncturing front end, patient is forced more to send out
Power stabs abdominal cavity by the strength of vertical pressing, rotates due to lacking, and puncture mode is mainly rendered as dangerous " frank and outspoken "
Mode, therefore inevitably power is big and be difficult to experience " the prominent empty sense " into abdominal cavity moment, it is especially easily out of control and directly disclose into abdomen
Chamber seriously damages internal organs, jeopardizes patients ' lives safety.
Summary of the invention
The present invention is to avoid above-mentioned existing deficiencies in the technology, by active rotation inner sleeve, especially
Extending arm of force when inner sleeve rotation, internal and external casing buckle drives the coaxial corotating of outer tube, and it is spiral steadily to enter abdominal cavity, because
This is placed in outer tube in the puncture of stomach wall miniature incision in laparoscopic surgery by force, i.e., more when stomach wall establishes the big channel of casing
It is safe, laborsaving, convenient.
The present invention adopts the following technical scheme that in order to solve the technical problem
1, booster type corotating abdomen wall puncture double-jacket tube, it is characterized in that: inner sleeve (1) is hollow tubular structure, one end
For conical pipe (11), surface is rotary threaded (111), and middle part is column tube (12), and the other end is circular enclosure (13), circular enclosure
Central part is small circular holes (131), and small circular holes are covered with elastic seal cap (1311), is provided with symmetrical stretching, extension on the outside of circular enclosure
Butterfly leaf (132), be provided with the polygon bayonet of inner sleeve (133) on the inside of circular enclosure, mutually fastened with the polygon snap-gauge of outer tube (22)
It is fixed.
2, booster type corotating abdomen wall puncture double-jacket tube, it is characterized in that: outer tube (2) is hollow tubular structure, one end
For flat mouth end (21), the polygon snap-gauge of outer tube (22) is provided on the outside of the other end, center is large circular apertures (23), large circular apertures
It is covered with elastic seal cap (231), the conical pipe (11) of inner sleeve passes through the elastic seal cap (231) and large circular apertures of outer tube
(23) it is inserted into, the polygon bayonet (133) of inner sleeve and the polygon snap-gauge (22) of outer tube fasten.
3, booster type corotating abdomen wall puncture double-jacket tube, it is characterized in that: puncture awl (3) passes through the elastic seal cap of inner sleeve
(1311) and small circular holes (131) insertion and run through internal and external casing, puncture awl pedestal (33) are pressed when abdomen wall puncture, in rotation
The butterfly leaf (132) of casing outreach drives outer tube (2) coaxial corotation to transfer the spiral stomach wall that steadily runs through and is placed into abdominal cavity.
Compared with the prior art, the invention has the advantages that:
1, according to biomethanics and abdomen wall puncture principle, while the centre of the palm presses puncture awl pedestal, thumb can be certainly
By pushing butterfly leaf, thus active rotation inner sleeve, the inner sleeve pipe screw thread in puncture front end in stomach wall helically steadily pass through by formula
It wears abdominal wall tissue and enters abdominal cavity, it is safer.
2, the butterfly leaf of the circular enclosure and its outreach of inner sleeve be push inner sleeve rotation and the extended arm of force, therefore rotate in
Casing is more laborsaving.
3, in abdomen wall puncture, inner sleeve is connected with outer tube buckle, and outer tube follows inner sleeve to rotate, and is convenient for outer tube
Steadily abdominal cavity is placed into through stomach wall.

Specific embodiment
Conical pipe (11) column tube (12) of inner sleeve (1) is passed through to the elastic seal cap (231) of outer tube (2), and its
Big hole (23) and outer tube sheath (24) and through merging outer tube (2), conical pipe (11) conical section surmounts flat mouth end
(21), the polygon bayonet (133) at this time in the circular enclosure (13) of inner sleeve (1) is matched with the polygon snap-gauge (22) of outer tube (2)
It fastens.
Puncture awl (3) is punctured by the elastic seal cap (1311) of inner sleeve (1) and the column tube (12) of inner sleeve (1)
Cone (3) conehead (31) surmounts the conical pipe (11) (Fig. 6) of inner sleeve (1).
Patient holds inner sleeve (1), outer tube (2) and the puncture awl (3) (Fig. 6) being composed, from skin of abdomen notch
It is forcibly inserted into abdominal cavity, the pedestal (33) of centre of the palm pressing puncture awl (3), thumb promotion inner sleeve (1) butterfly leaf (132) continuously rotation
Turn, the rotary threaded (111) positioned at inner sleeve conical pipe (11) surface for puncturing front end spirally enters abdominal cavity, due to inner sleeve
Polygon between pipe (1) and outer tube (2) is fastened and connected, therefore and drives outer tube (2) to rotate and spiral steadily run through abdomen
Wall simultaneously enters abdominal cavity.
It withdraws and exits inner sleeve (1) and puncture awl (3), the outer tube (2) that stomach wall is retained is as the big channel for entering and leaving abdominal cavity.
