Description

A kind of air shuttle valve of Novel laparoscope operation puncture outfit

Technical field

The utility model is related to minimally invasive cell phone apparatus technical field, especially a kind of Novel laparoscope operation puncture outfit Air shuttle valve.

Background technology

Laparoscopic surgery is the invasive methods that a new development is got up, and is that one of following operation method development necessarily becomes Gesture.With advancing by leaps and bounds for industrial manufacturing technology, be fused to carry out new technology, the new method of related discipline have established firm base Plinth, in addition the operation that doctor is more and more consummate so that many past open operations have been replaced now by intracavity operation, Considerably increase surgical selection chance.Retroperitoneoscopictechnique conventional method is to make three 1 centimetre of small notch in patient's waist, respectively Be inserted into a pipe-like service aisle for being called " trocar " (i.e. puncture outfit), later every operation by these three pipelines into Row；The step similary with open surgery is completed under television monitoring with special lengthening surgical instrument again, reaches same operation Effect.

The advantages of Two trocars retroperitoneoscopictechnique is very it will be evident that being wound very little first, it is only necessary to 2 osculums, scar Very little, this point are more worth noting for young man and the women to like to be beautiful.Second, the entrance performed the operation as single-broadsword event, to week The damage for enclosing tissue minimizes, and the postoperative chance to stick together becomes smaller.Third, patient's postoperative wound pain are substantially reduced.The Four, length of stay is less, as long as 2-3 days had can leave hospital, complete recovery of health and can devote oneself to work within 7 days, so as to make trouble Person, which bears expenses, to be greatly reduced, while hospital bed turnover rate is accelerated.

Endoscopic technique is long-standing.From the first pelviscope of 1901 to the diagnostic laparoscope of 1910, so far Through there is more than 100 years history.Due to the invention of cold light source, glass fibre endoscope, the artificial gas of German Semm after into the seventies Abdomen monitor device --- automatic pneumoperitoneum apparatus comes out, and so far laparoscopic surgery grows up on a grand and spectacular scale.Because it damages small, nothing Laparotomy ventrotomy is needed, is received on both side by doctor and patient quickly.The Nezhat doctor in the U.S. in 1980 begins to use TV abdominal cavity Mirror is performed the operation.Surgical field of view is made clearly to be presented on fluorescent screen, expands the visual field, many doctors can see simultaneously to perform the operation Journey conducive to the exchange and discussion of technology, also allows for the cooperation of assistant and the assistance of Anesthetist.The Kurt of later stage eighties Germany Semm teaching inventives create many new surgical instruments and technology.Such as：Suture instruments under mirror, flushing pump, it is various clamp, cut, group Close grinder, cutter etc..The means of present mirror lower hemostasia are varied：Have monopolar coagulation, bipolar coagulation, ligation lasso, The progress of the technologies such as interior suturing skill, titanium folder, stapler makes more complicated operation be completed under mirror.Reich H are done within 1988 First case total hysterectomy under laparoscopy, hereafter gynecological surgery range the more do the more big, almost 90% gynecological surgery can be It is completed under laparoscope.

In order to which in the relatively spacious surgical procedure space of intraperitoneal manufacture one, doctor needs to use CO₂Gas is to patient's abdomen Chamber inflates (gas making abdomen), and pneumoperitoneum pressure is maintained under the dynamic stability pressure of about 2 atmospheric pressure.In order to avoid pneumoperitoneum leaks Gas, it is necessary to device --- a choke valve system that can play tissue gas leakage is designed on puncture outfit.Baffle system Composition mainly have several parts：Level-one air shuttle valve, two level air shuttle valve, air shuttle valve fixing device etc..

Existing choke valve technology is mainly divided to two major class：First be monomer single hole design class, second be blade type design class. Monomer single hole air shuttle valve, mostly there are the problem of minor diameter instrument and incompatible major diameter instrument, air valve is easily torn and leaks Gas；And blade type designs, and is sufficiently improved in compatibility, but its processing and assembly cost are expensive, are such as suitable for Disposable puncture outfit.

Utility model content

In view of the above problems, the purpose of this utility model is to provide a kind of Novel laparoscope operation puncture outfit Air shuttle valve improves the compatibility issue of minor diameter instrument and major diameter instrument by improving air shuttle valve moulding and structure design.

The technical solution of the utility model is：A kind of air shuttle valve of Novel laparoscope operation puncture outfit, leads to including instrument Road 1, valve body 2, sealing ring 3 and reinforcing rib 4 connect instrument channel 1 on the valve body 2, sealing are connected in the instrument channel 1 Circle, the reinforcing rib 4 are arranged on valve body 2.

Further, the wall thickness of the instrument channel 1 gradually increases from bottom to top.

Further, under the cross-sectional diameter of the sealing ring 3 becomes larger again from large to small, and upper cross-sectional diameter is more than Cross-sectional diameter, the purpose of this design are to enhance the tear resistance of valve body.

Compared with prior art, the beneficial effects of the utility model are：The utility model is by changing gas-blocking valve structure It makes, the use including opening, thickness change, reinforcing rib, is that the deformation elasticity of air shuttle valve and resilience are obtained for raising, because This can be common to the disengaging of 5mm and 10mm or even 12mm instruments.It is simple due to designing, thus processing cost is lower, assembling is simpler Just.
