Abstract
The invention belongs to medical instruments field, especially a kind of laparoscopic medical instrument.In order to solve the problem of in laparoscopic surgery stamp the card easily easy gas leakage of sliding and safety, the present invention devise one kind can closed fixable stamp block, including stamp card with a scale, sealing shroud and with suctorial fixed device；There is herringbone to lock flat and unblock button in fixed device.The present invention, for fixed stamp card, prevents gas leakage in laparoscopic surgery, and preventing subcutaneous swollen and protection abdominal organs has positive effect.
Description
Technical field
The invention belongs to medical instruments field, especially a kind of laparoscopic medical instrument field.
Background technique
It improves with the development of science and technology, " minimally invasive " is gradually deep into surgical operation as brand-new surgery theory
Various fields.Minimally Invasive Surgery generally refers to carry out using the modern medical equipments such as laparoscope, thoracoscope, arthroscope and relevant device
Operation, not only with wound is small, pain is light, restores fast superiority, and have that surgical quality is higher, long-term effect is more preferable
Advantage.Stamp card is necessary the instrument of laparoscopic surgery, but clinically used stamp card has the following problems at present: 1. stamps block and
Stomach wall stationarity is poor, and stamp card is easy to move in stomach wall puncture in operation, influences surgical procedure.2. between stamp card and stomach wall puncture
Lack sealing, carbon dioxide gas is caused to overflow outside abdominal cavity from stomach wall puncture, influence that pneumoperitoneum pressure is constant and surgical procedure, increases
Carbon dioxide-depleted amount.It is sealed 3. lacking between stamp card and stomach wall puncture, carbon dioxide can enter subcutaneous group from puncture peritonaeum side
It knits, forms pneumoderm.Pneumoderm not only influences surgical procedure, and increases the risk of hypercapnia and infection.4. the
One stamp holding is generally " blind to wear " when entering stomach wall, and patient by virtue of experience determines the dynamics and depth that stamp card punctures, may be accidentally
Hurt internal organs.
Summary of the invention
In view of at present stamp card use process in the problem, the present invention send out it is bright it is a kind of it is firm, closed, can
Show deep stamp card.
In order to realize the above technical goal, the present invention adopts the following technical scheme:
The present invention includes: stamp card with a scale, sealing shroud and with suctorial fixed device.
The stamp card with a scale refers on the puncture tube of stamp card with scale.On the one hand this scale can fathom,
On the other hand it can increase the frictional force of stamp card and abdominal wall tissue.
The sealing shroud is fixed on stamp card puncture tube, by the ball missing shape thin-walled group for being in hollow cylinder and central through hole
At hollow cylinder body length is 5 millimeters~30 millimeters, and inflated diameter is stamp card cylinder overall diameter, and ball missing shape thin-walled wall thickness is 0.1
Millimeter~3 millimeters, central through hole diameter are stamp card cylinder overall diameter, and ball missing shape thin walled aperture end diameter is 1.5~4 times of stamp card cylinders
Outer diameter.
The mode that the sealing shroud is fixed on stamp card puncture tube is fixed including being screwed, being embedded in the modes such as groove.
It is possible to further which multiple screw holes or groove, adjusting position as needed is arranged on stamp card puncture tube.
The assembly of the fixed device and sucker, suction cup portion are made of in bowl-shape elastic material, cross section
Maximum gauge is 2~6 times of stamp card cylinder overall diameters.The bottom of bowl position of sucker is connected and fixed device.Fixed device include shell,
Unblock button and herringbone flat.The locking of fixed device part is to lock flat by 2~3 groups of herringbones to realize.Lineup's word
Flat is locked to be made of a fixed bracket and a bullet tongue.Support bracket fastened upper section is connected on the shell of fixed device, middle section
To the oppositely extending of sucker position, lower section is parallel with the puncture tube of stamp card.The bullet tongue adjacent with fixed bracket is connected to solid
Determine to extend on the shell of device and to the direction of sucker position.2~3 groups of herringbones lock flat it is right on the cross section of shell
Claim distribution.Unblock button is installed on shell, being unlocked by pressing button makes to play tongue not with the graduation mark releasing of stamp card puncture tube i.e.
Unlock can be achieved.Fixed device only allows to stab the puncture tube portion blocked relative to the suction with fixed device in the state of locking
Disk slides in one direction, i.e. direction sliding where human body inwardly；Conversely, sliding to another direction, then elastic slice is stuck in
On the cylinder for stabbing card puncture tube.In the state of unlock, that stabs card punctures tube portion relative to the sucker with fixed device two
A side's upward sliding.
The material of the suction cup portion of the assembly of the sealing shroud and fixed device and sucker uses medical grade rubber, including day
Right rubber, silicon rubber, butyl rubber, polyurethane rubber etc..
Detailed description of the invention
The present invention will be further described in the following with reference to the drawings and specific embodiments.
Fig. 1 is schematic diagram of the present invention
Fig. 2 is the half sectional view of sucker of the present invention with fixed device
Fig. 3 is the cross-sectional view of sealing shroud of the present invention
In figure: 1, with a scale stamp card, 2, sealing shroud, 3, the assembly of fixed device and sucker, 4, sucker, 5, outside fixed device
Shell, 6, herringbone lock flat fixed frame, 7, herringbone lock flat bullet tongue, 8, unblock button.
Specific embodiment
Illustrate the present invention below with reference to embodiment.
See attached drawing 1, the present invention by the assembly 3 of stamp card 1 with a scale, sealing shroud 2, fixed device and sucker, sucker 4,
Fixture enclosure 5, herringbone lock flat fixed frame 6, herringbone locks flat bullet tongue 7, unblock button 8 forms.
It is staggeredly symmetrical in 90 degree that two groups of herringbones as used in the present invention lock fixed frame 6, bullet tongue 7 in flat
In on the shell of fixed device.Two unblock buttons 8 are mounted on the position for corresponding on shell and playing tongue 7.Being unlocked by pressing button
8, corresponding bullet tongue 7 and the cylinder contact jaw for stabbing card 1 with a scale lift, and the assembly 3 of fixed device and sucker can be in band
Bidirectional slide on the cylinder of the stamp card 1 of scale.It is stuck on the cylinder of stamp card 1 with a scale conversely, playing tongue 7, and can only be to phase
Puncture extreme direction sliding for stamp card 1 with a scale.
The internal diameter of used stamp card is 10 millimeters, and the end diameter of sealing shroud is 10 millimeters, and outside diameter diameter is 20
Millimeter, sealing shroud length are 20 millimeters.The cross section maximum gauge of sucker is 40 millimeters.Used material is silicon rubber.
The sealing shroud is located on the cylinder of the cutting tip of stamp card 1 with a scale, is the starting point of scale.
Use time-division following steps:
1, patient's cortex is cut, stamp card 1 is punctured into abdominal cavity of patients until because the sealing shroud 2 of resistance contraction is completely into body
It is interior.
2, it to external drawing stamp card 1, is created so as to block puncture peritonaeum side in the sealing shroud 2 that form is unfolded in intraperitoneal recovery
Mouthful.
3, push the assembly 3 of fixed device and sucker to patient skin direction, until sucker 4 is held in patient skin
On.Meanwhile the graduation mark on stamp card 1 can be observed, estimation is made to the abdominal tissues thickness of patient, convenient for the stamp after several times
When card punctures, play a protective role to intraperitoneal tissue.
4, postoperative, being unlocked by pressing button 8, while being pulled outwardly the assembly 3 of fixation device and sucker with fixed device
So that it is separated with patient body.
5, continue drawing stamp card 1 outward, until from intraperitoneal taking-up.
