Single-hole laparoscopic enters pathsTechnical field
Enter paths the utility model relates to a kind of single-hole laparoscopic, belongs to the field of medical instrument technology.
Background technique
Surgery is developed so far, and enters the new era of minimally invasive surgery.It is Minimally Invasive Surgery through navel single-hole laparoscopic technologyOne kind, is a kind of emerging Minimally Invasive Surgery, and minimally invasive theory is better than traditional laparoscopic surgery.It passes through a small navel notch(2-3cm) merging one channel multi-path laparoscopic instrument is performed the operation.
Single-hole laparoscopic technology needs specially to enter paths, has many different paths that enter on the market at present and is used to faceBed practice, ensure that safety, reliability and the convenience of operation.But at present it is both domestic and external enter paths it is expensive, meshIt is preceding on the market it is generally the least expensive it is domestic enter paths price at 3000 yuans, the product price of import is more expensive, is not suitable for ChinaNational conditions.
Therefore there is applicant to have attempted to solve this problem, using conventional operation consumptive material, make by oneself into paths, ShenPlease number: 201620783623.5, patent name be a kind of self-control laparoscope single-hole multi-channel device, but the patented technology have it is as followsDisadvantage:
One, former patent is using molding laparoscope puncture outfit, and at high cost, domestic is cheapest also at thousand yuan or more；In additionThe price of incision protective sleeve entirely enters 2500 yuan of paths or so.Although having compared with molding single-hole laparoscopic enters pathsPrice advantage, but still have room for improvement；
Two, former patent uses laparoscope puncture outfit, and puncture outfit head end is larger, interferes instrument in art close, often results in deviceTool is fought, and influences to operate；Single-hole laparoscopic surgery operation skill is higher compared with the requirement of conventional porous laparoscope, essentially consists in device in artTool is entered by same duct, if instrument is difficult to close to each other, will seriously affect procedure, or even be difficult to complete to perform the operation.ThisFor the primary limitation of former patent.
Utility model content
According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: providing a kind of single hole abdomenHysteroscope enters paths, and structure is simple, low manufacture cost, easier to operate.
Single-hole laparoscopic described in the utility model enters paths, including gloves, it is characterised in that: on gloves extremelyThe end of a few fingerstall becomes through-hole by cross-section, and through hole is provided with instrument and penetrates pipe, instrument penetrates pipe for instrumentSealing penetrates.
When instrument penetrates the connection of Guan Yu through-hole, preferably following several sets of plan:
The pipe shaft that scheme one, the instrument penetrate pipe is provided with external fingerstall, instrument from its inner sidewall to lateral wallIt penetrates pipe to penetrate in through-hole, instrument is penetrated by pipe by fastener in the lateral wall of fingerstall and is fixed in through-hole.
Scheme two, the instrument penetrate pipe sleeve on fingerstall, and fingerstall end forms fingerstall flanging, and instrument penetrates pipeIt is clipped between fingerstall flanging and fingerstall, instrument is penetrated by pipe by fastener in the lateral wall of fingerstall flanging and is fixed on fingerstallBetween flanging and fingerstall.
Scheme three, the instrument, which penetrate on pipe, is cased at least one layer of external fingerstall, offers out in the end of external fingerstallMouthful, instrument penetrates pipe and penetrates in through-hole, instrument is penetrated pipe by fastener in the lateral wall of fingerstall and is fixed in through-hole.
Wherein, scheme one the following steps are included:
One, prepare material, material has gloves, external fingerstall, instrument to penetrate pipe and silk thread；
Two, it makes, the end scissors of external fingerstall is cross-section, and one end of external fingerstall is worn from one end that instrument penetrates pipeEnter, then be pierced by from the other end that instrument penetrates pipe, turned up after being pierced by, then is ligatured by silk thread；The other end of external fingerstall also intoRow turns up, and is ligatured by silk thread；The fingerstall end of gloves is subjected to cross-section formation through-hole, then the instrument that will be cased with external fingerstallIt penetrates pipe to penetrate in through-hole, instrument is penetrated by pipe by silk thread in fingerstall lateral wall and is fixed in through-hole.
Scheme two the following steps are included:
One, prepare material, material has gloves, instrument to penetrate pipe and silk thread；
Two, it makes, the fingerstall end of gloves is subjected to cross-section formation through-hole, the end of fingerstall is penetrated the one of pipe from instrumentEnd penetrates, then is pierced by from the other end that instrument penetrates pipe, turns up after being pierced by, so that fingerstall flanging is formed, so that instrument be wornEnter pipe clamp between fingerstall flanging and fingerstall, penetrates instrument in such a way that silk thread ligatures in the lateral wall of fingerstall flangingPipe is fixed between fingerstall flanging and fingerstall.
Scheme three the following steps are included:
One, prepare material, material has gloves, external fingerstall, instrument to penetrate pipe and silk thread；
Two, it makes, opens up opening in the end of external fingerstall, external fingerstall is covered and is penetrated on pipe in instrument, by glovesFingerstall end carries out cross-section formation through-hole, then the instrument for being cased with external fingerstall is penetrated pipe and is penetrated in through-hole, in the outer of fingerstallInstrument is penetrated pipe in such a way that silk thread ligatures and is fixed in through-hole by side wall.
The further preferred fastener is silk thread.
The further preferred instrument penetrates pipe lateral wall and offers thread groove.
The further preferred instrument penetrates pipe in side conical tube structure.
Compared with prior art, the utility model has the following beneficial effects:
One, the design draws materials convenient, and production is simple.It is preoperative to make at once for common aseptic apparatus of performing the operation, sterile, safety.
Two, low manufacture cost, operation consumptive material RMB less than 800 yuan, (wherein, 750 yuan of incision protective sleeve or so, wear by instrumentEnter pipe, gloves, silk thread to take within 50 yuan), 3000 yuan generally the least expensive lower than the country enter paths.In a small amount of production, Ke YizhiThe connector using disposable aspirator both ends is connect, penetrates pipe with connector to serve as instrument；Its cost is lower when batch production, can be withIt is customized instrument and penetrates pipe.
Three, the design has the following advantages compared with former patented technology:
1, solve the problems, such as that former patent is at high cost using molding laparoscope puncture outfit, this technology only needs instrument to penetrate pipe(it can be directly used two end connectors of aspirator when a small amount of production, its cost is lower when batch production, can be customized instrumentPenetrate pipe), gloves, silk thread, expend 50 yuan within.2, solve the problems, such as that distance is larger, it is close to be difficult between former patent instrument, thisTechnology does not increase instrumentation spacing while guaranteeing air-tightness, almost can be with zero distance close to easier to operate between instrument.
