The specific embodiment

Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4-a, Fig. 4-b, this utility model comprises binding clip 1, prolongs pipe 2, handle chassis 3 and handle 4, prolong pipe 2 and fixedly connected with handle chassis 3, binding clip 1 tail end is fixedlyed connected with core bar 6, binding clip 1 and core bar 6 can be in prolonging pipe 2 before and after slip.Be provided with in the handle chassis 3 and can control that binding clip 1 stretches out or indentation prolongs the telescoping mechanism 7 of pipe 2, this telescoping mechanism 7 is by pedestal 8, slide block 10, runner 13 and core bar 6 are formed, pedestal 8 is fixed in the handle chassis 3, pedestal 8 is provided with first chute 9, slide block 10 can slide front and back in first chute 9, runner 13 can be that rotate in the axle center with first rotating shaft 12 on the pedestal 8, runner 13 is provided with cylinder 14, cylinder 14 can slide in second chute 11 on slide block 10, runner 13 is fixedlyed connected with handle 4, when so handle 4 rotates, slide block 10 can slide front and back in pedestal 8, slide block 10 is fixedlyed connected with the tail end of core bar 6, so the rotation of handle 4 has been controlled stretching out of binding clip 1 or bounced back.

As Fig. 5-a, Fig. 5-b, shown in Figure 6, pedestal 8 dorsal parts are provided with the device that can stop slide block 10 to slide, this device is made up of the hook protruding 18 on gear 15, spring leaf 17, pin 19, spring 20 and the slide block 10, described gear 15 can be that rotate in the axle center with second rotating shaft 25 on the pedestal 8, spring leaf 17 can guarantee that gear 15 can only one-directional rotation, slide once in slide block 10 front and back, hook protruding 18 can rotate teeth by driven gear 15.Gear 15 is provided with gear hole 16, and pedestal 8 is provided with pedestal hole 22, when gear 15 turns to certain angle, gear hole 16 and pedestal hole 22 are coaxial, and pin 19 enters in gear 15 and the pedestal hole 22 under the effect of spring 20, in through first chute 9, stoped slide block 10 to front slide.

As Fig. 7-a, Fig. 7-b, Fig. 8-a, Fig. 8-b, Fig. 8-c, shown in, binding clip 1 is hook-shaped head end 23 and elastic part 24 by two and forms, and the original state of elastic part 24 is open configuration, when binding clip 1 stretches out when prolonging pipe 2 fully, two head end 23 opened with certain angle are the jaw shape; When binding clip 1 partially retracted prolongation managed 2, two head ends 23 were hook-shaped owing to prolong the constriction effect closure of pipe 2; When binding clip 1 is withdrawn when prolonging pipe 2 fully, the inclined-plane 26 that prolongs pipe 2 head ends is directly exposed, because it is thinner to prolong pipe 2 diameters, less than 5mm, so inclined-plane 26 can enter in the body cavity as sharp orifice directly puncture body surface such as stomach wall, sets up the process of body surface otch when having simplified Minimally Invasive Surgery greatly.

Shown in Fig. 1, Fig. 5-b, prolong pipe 2 outer wrapping insulant, the shell of handle chassis 3 and handle 4 are made for insulant, pedestal 8 is provided with electrode 21, use so this utility model can merge with medical apparatus and instruments such as high frequency main frame, in operation binding clip 1 can play separations, extractings, electric with fixed attention, multiple function such as TURP.

Product export state of the present utility model is gear hole 16 and pedestal hole 22 disalignments, and binding clip 1 stretches out and is set back in and prolongs pipe 2 respectively once during operation, carries out the cleaning of apparatus after art finishes, tail end sealing cap 5 is opened, inject clear water, binding clip 1 stretches once again, goes out blood stains etc.Continuous use along with product, gear 15 constantly rotates coaxial until gear hole 16 and pedestal hole 22, pin 19 enters in first chute 9 and stops slide block 10, and binding clip 1 again can't stretch out and prolong pipe 2, has therefore prevented from excessively using the actual application problems such as binding clip 1 fracture that cause because of apparatus.

The above-mentioned specific embodiment is used for this utility model of explaining; rather than this utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to this utility model is made all fall into protection domain of the present utility model.
