Description

A kind of sundries of getting

Technical field

This utility model relates to field of surgical, relates in particular to a kind of being used for to get sundries to what in vivo excision thing took out.

Background technology

Minimally Invasive Surgery is meant the operation that modern medical equipment such as utilizing peritoneoscope, thoracoscope and relevant device carry out; Minimally Invasive Surgery need not be operated on; Only need open 1-3 0.5-1 centimetre aperture on one's body patient, patient's preventing from scar, painless, only need just can accomplish inspection, treatment, rehabilitation overall process in 3-5 days.Minimally Invasive Surgery has reduced the injury of traditional operation to human body, has greatly reduced inconvenience that disease brings to the patient and painful.Advantage such as Minimally Invasive Surgery has that wound is little, light pain, recovery are fast more and more receives doctor and patient's welcome.But Minimally Invasive Surgery is because wound is little, and excision thing in vivo is not easy to take out of, and this is the difficult problem that Minimally Invasive Surgery need solve always.

Summary of the invention

The purpose of this utility model is, provides that a kind of intravital excision thing takes out when being convenient to operation gets sundries.

To achieve these goals; The sundries of getting that this utility model provides comprise outer tube, push rod, bag and backguy; The front opening of outer tube, push rod can be made reciprocating sliding campaign, push rod in outer tube front end is provided with the shell fragment of pair of opposing, and bag is provided with a circle perforated chamber along bag mouth; Perforated chamber has cutting opening; Said a pair of shell fragment penetrates the perforated chamber from the both sides of cutting opening respectively, and shell fragment is in outer tube and receive the elasticity extruding of outer tube, and bag is accommodated in the outer tube foldedly; One end of backguy runs through after the perforated chamber from the opposite side of the cutting opening back of coming out from a side of cutting opening makes a call to a slip-knot, and the other end of backguy stretches out from the rear end of outer tube behind the front end entering outer tube of outer tube earlier after passing slip-knot again.

What this utility model provided gets sundries when not using, and shell fragment and bag all are accommodated in the outer tube, have dwindled occupation space greatly, can insert easily in the body; Can release outer tube to shell fragment and bag after getting in the body, shell fragment opens bag mouth, is convenient to put into bag to the excision thing; When in body, taking out, shrink bag mouth with backguy, and in the shell fragment withdrawal outer tube.This utility model when the wound, all can dwindle its volume in the turnover body, reduced the area of wound and stressed, has alleviated patient's the pain of injury; Can fully open bag mouth in the time of in vivo, be convenient to the doctor and put into bag to the excision thing.

The specific embodiment

Referring to Fig. 1, outer tube 1 is a columniform hollow pipe, and both ends open.Be provided with the handgrip 11 that is fixed on the outer tube 1 in the rear end of outer tube 1, handgrip 11 comprises symmetrically arranged two annulus 12, and handgrip 11 has not only made things convenient for gripping of outer tube 1 when using, and handsome in appearance, and handgrip 11 can also be other shapes.Push rod 2 is also cylindrical, in outer tube 1, but and phase outer tube 1 do the reciprocating sliding campaign; Stretch out from the rear end of outer tube 1 its rear end, for ease of the push-and-pull to push rod 2, is provided with draw ring 21 in the rear end of push rod 2; For weight reduction and saving cost, push rod 2 also is a hollow pipe in the present embodiment.

Referring to Fig. 2 and Fig. 3, the front end of push rod 2 is provided with the shell fragment 3 of pair of opposing, and shell fragment 3 is circular arc substantially by the elastomeric material manufacturing.Referring to Fig. 4, an end of shell fragment 3 has through hole, has groove and through hole on the union joint 9, and the end that shell fragment 3 has through hole inserts in this groove, and pin 8 is pressed in the through hole, is pressed into union joint 9 front end of push rod 2 again, thereby is installed in shell fragment 3 on the push rod 2.

Referring to 6, bag 4 is from bag mouth to the diminishing taper in bottom, and bag mouth is maximum, be convenient to toward bag in, place object, and the bottom is minimum, makes the bag maintenance volume minimum of dress thing, helps taking out from wound.Referring to Fig. 4, bag 4 is provided with a circle perforated chamber 41 along bag mouth, and perforated chamber 41 has cutting opening, and two shell fragments 3 penetrate the perforated chamber 41 from the both

sides

42,43 of cutting opening respectively.For preventing that shell fragment 3 from wearing out bag 4, be provided with protective sleeve 31 in the outer end of shell fragment 3, protective sleeve 31 is one-body molded, when shell fragment 3 opens, plays the protection to bag well, after in the protective sleeve 31 insertion perforated chamber 41, inserts shell fragment 3 more earlier during installation.One end of backguy 5 is from the perforated chamber 41 of a side 42 entering bags of cutting opening; Running through perforated chamber 41 back opposite sides 43 from cutting opening comes out; Make a call to a slip-knot afterwards again, the other end of backguy 5 passes that the front end from outer tube 1 gets into outer tube 1 behind this slip-knot, runs through outer tube 1 back and stretches out from the rear end of outer tube 1.This slip-knot can slide along backguy, and pulling backguy 5 is stretched out the end of outer tube 1 rear end and can be shunk the bag mouth of bag 4.

During assembling, earlier shell fragment 3 is clamped relatively, rolled successively after up draining air to bag 4 from the bottom, be close to shell fragment 3 to the bag of rolling 4 at last, pack shell fragment 3 and bag 4 together in the outer tube 1 again.Referring to Fig. 1, after assembling was accomplished, bag 4 was accommodated in the outer tube 1 foldedly, and shell fragment 3 and receives the elasticity extruding of outer tube 1 inwall also in outer tube 1.The part that outer tube 1 is stretched out in backguy 5 is wrapped on the push rod 2; The end that outer tube 1 is stretched out in backguy 5 is provided with elastic ring 6; Elastic ring 6 is buckled on the draw ring 21 of push rod 2 rear ends, can prevent that like this backguy 5 from being broken preserving and carry in the process, also makes simultaneously to get the sundries overall structure and more be becoming tight and gather.

Specify the work process of getting sundries below in conjunction with Fig. 1, Fig. 5 and Fig. 6.In at first inserting body to the front end of getting sundries from wound, because when not using (as shown in Figure 1), shell fragment 3 is all taken in the outer tube 1 with bag 4, the front end of getting sundries only outer tube takes up room, and wound can be opened very for a short time.After the front end of getting sundries gets in the body; Discharge elastic ring 6, promote push rod 2 and release outer tube 1 to shell fragment 3 and bag 4, shell fragment 3 opens at the bag mouth that recovers the following bag 4 of elastic force effect; Like Fig. 5 and shown in Figure 6, can put into bag to the excision thing from open bag mouth.After treating that the excision thing is put into bag 4; Pulling-pushing rod 2 toward the rear end, draw in shell fragment 3 in the outer tube 1, and shell fragment 3 is separated with bag 4 simultaneously; Then shrink the bag mouth of bag 4, take out the whole sundries of getting in the body through wound with the excision thing that is contained in the bag 4 at last through pulling backguy 5.This utility model when the wound, all can dwindle its volume in the turnover body, reduced the area of wound and stressed, has alleviated patient's the pain of injury; Can fully open bag mouth in the time of in vivo, be convenient to the doctor and put into bag to the excision thing.
