Description

Cyst suction pump

Technical field:

This utility model belongs to medical operating articles for use, is specifically related in gynecological laparoscopy cystectomy the cyst suction pump used, and is mainly used in cyst wall in art and punctures, fixes and cystic fluid attraction, and can assist to peel off cyst wall.

Technical background:

Laparoscopic surgery reaches its maturity in recent years, it being widely used in Gynecology. laparoscopic surgery has that operation wound is little, go out insufficiency of blood, operating time is short, post-operative recovery stays the advantages such as cicatrix soon, hardly, significantly improving the quality of life after corrective surgery, cystectomy is accounting about 20% in gynecological laparoscopic operation.In existing laparoscopic surgery, absorption and the cyst of cystic fluid are peeled off employing and are utilized puncture needle to wear out cyst wall, recycling suction pump absorption cystic fluid, finally utilize hoe scaler to be peeled off from tissue by cyst wall.Owing to using different apparatus separate operations, first puncturing, attract, peel off, the most original sucting apparatus uses cystic fluid suction catheter to attract in advance, it is impossible to location, operating process cannot be avoided cystic fluid reveal and cause free muscular tumor cell contamination abdominal cavity, cause tumor to move the possibility grown.Wish development one special utility medical apparatus and instruments, simply, effectively at cyst wall puncture, fix and during cystic fluid attraction, stripping cyst wall, it is to avoid cystic fluid is revealed and caused free muscular tumor cell contamination abdominal cavity to cause transfer.

Summary of the invention:

It is an object of the invention to: overcome the deficiency of existing art formula, innovative design one surgical instrument-cyst suction pump, in completing the attraction of liquid in cyst, cyst wall can being fixed and assist the stripping process of adhesion, prevent from revealing cystic fluid pollute abdominal cavity and cause transplanting.

This utility model cyst suction pump solves the technical problem that and be the technical scheme is that

Cyst suction pump is by the rustless steel pipette of the double sacculus of band silicone rubber, pin and plastic handles composition in rustless steel, it is characterized in that pipette front end has double sacculus, in sacculus enters cyst wall before guiding after needle-penetration cyst wall under the peritoneoscope visual field, fill front sacculus, the most successively expand after sacculus, forward and backward sacculus splashed after clamp cyst wall seal simultaneously puncture orifice prevent cystic fluid from puncture orifice leakage.Pin in extracting out behind location, attracts cystic fluid by pipette, drives cyst suction pump to pull cyst wall to assist to peel off cyst by handle.(referring to accompanying drawing 1 structural representation).

Pipette is made up of double cuff pipes and inner tube.Double cuff pipes are by check valve, adapter, silicone rubber three lumen and sacculus is bonding assembles, and stainless steel tube fit on termination forms inner tube, is then assemblied in outside inner tube by glued good double cuff pipes and makes pipette.(referring to accompanying drawing 2 structural representation)

Interior pin is made (referring to accompanying drawing 3 structural representation) by needle tubing fit on plastic reducer union, after pipette fit on handle, makes cyst suction pump in interior pin is inserted into pipette.

During use, first cyst suction pump front end propping up cyst wall, rotation subsequently pushes away the interior pin in pipette and punctures cyst wall, then advance suction pump, pushed in cyst by front sacculus.Before first full sacculus to make cyst in mentioning state, more full after sacculus swell sealing puncture orifice to two sacculus.After treating that two sacculus are full, former and later two full sacculus can clamp cyst wall, fix.Behind double sacculus location, extract interior pin by pipette sucking-off cyst fluid.In cyst after liquid extraction, so can promote, mobile cyst carries out peeling off operation.Release the gas (or liquid) in sacculus, shrink sacculus and take out cyst suction pump.Operating process double sacculus folder cyst wall, sealed penetration, operation technique punctures, and seals, and attracts, and pulls and assists to peel off cyst, can be continuously finished, prevent cystic fluid from leaking outside.

This utility model has a following beneficial effect:

1, cyst suction pump uses doctor's most familiar of sacculus seal en-hancement scheme, it is simple to doctor accepts new art formula and training；

2, in cyst suction pump, pin punctures cyst wall, and two sacculus guiding front end the most full can grip cyst wall, be can reach by the location attraction of double sacculus and effectively prevents cystic fluid from leaking outside；

3, when cyst suction pump can reach fixing cyst by double sacculus location attractions, it is not necessary to the para-operational devices such as clamp；

4, in cyst suction pump, pin is hidden in pipette, and only puncture cyst moment exposes, and accidentally injures tissue probability less compared with using common puncture needle.

Detailed description of the invention:

Embodiment one

As shown in Figure 1, Figure 2, Figure 3 shows: this cyst suction pump is made up of pipette 1, interior pin 2 and handle 3.Pipette 1 is made up of double cuff pipe 1-1 and inner tube 1-2, double cuff pipe 1-1 are by check valve 1-1-1,1-1-2, adapter 1-1-3,1-1-4, silicone rubber three lumen 1-1-5 and sacculus 1-1-6,1-1-7 assemble, stainless steel tube 1-2-1 fit on termination 1-2-2 forms inner tube 1-2, is then assemblied in outside inner tube 1-2 by glued good double cuff pipe 1-1 and makes pipette 1.

Interior pin 2 is made up of needle tubing 2-1 fit on plastic reducer union 2-2；After pipette 1 fit on handle 3, in interior pin 2 is inserted into pipette 1, make cyst suction pump.
