Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1-5, the utility model provides a kind of technical solution: a kind of laparoscope with taking sundries, including outer tube 1, Outer tube one end be inserted by the aperture of abdomen it is intraperitoneal, the other end in vitro, the outer tube left end be screwed is connected with it is outer 2 are scooped, for dipping tissue fine crushing, interior bar 3 is rotatably connected in the outer tube, interior bar can be rotated relative to outer tube, the interior bar Left end be screwed be connected in scoop 4, inside scoop up effect rotating closed after dipping tissue, prevent take out during take out Object falls the outer inner sidewall scooped and is bonded with the interior lateral wall scooped；

The right end of the outer tube, which is screwed, is connected with sleeve 5, and sleeve is fixedly connected with outer tube, the inner sidewall of the sleeve Piston 6 is slidably connected, piston can horizontally slip in sleeve, and it is recessed that the inner sidewall front and rear sides of the sleeve are equipped with bar shaped Slot 7, the lateral wall front and rear sides of the piston are equipped with strip bulge 8, and groove and protrusion cooperate, and prevent piston in sleeve Interior rotation, the right end of the sleeve, which is screwed, is connected with end cap 9, and end cap is used to limit the position of piston, in the end cap Portion or so slidably connects push rod 11, the left end of the push rod and the piston through there is through-hole 1 in the through-hole one Right end, which is screwed, connects push rod promotion piston sliding；

The left end of the piston is equipped with shrinkage pool 12, and spiral groove is equipped in the shrinkage pool, and the right part of the interior bar is equipped with spiral shell Rotation protrusion, the spiral groove and the spiral salient cooperate, and spiral groove and spiral salient are 180 degree, and And screw pitch is sufficiently large, avoids making piston and interior bar mutually locked while by piston, but guarantee to relatively rotate, it will be straight Line conversion of motion is rotary motion, and interior scoop is allowed to scoop 180 degree of rotation mutually fastening, the right part set of the interior bar relative to outer There is spring 13, the spring is between the outer tube right side and the piston left side, and spring is for resetting.

Specifically, in described the left end of the right end that scoops and the interior bar be respectively equipped with up and down perforative through-hole 2 14 with Through-hole 3 15, the through-hole two are located on same axis with the through-hole three, and the inside of the through-hole two and through-hole three is passed through simultaneously It is installed with positioning pin 16, positioning pin prevents interior scoop when thread looseness from rotating or even falling off in intraperitoneal, the positioning relative to outer scoop For pin with the through-hole two and the through-hole three using being interference fitted, interference fit prevents positioning pin from falling off.

Specifically, two sides are equipped with block 17, the block and sleeve one to the lateral wall of the sleeve up and down The right end for forming the push rod is equipped with push top 18, and the push top is integrally formed with the push rod, in use, index finger and middle finger are distinguished Block is pulled, thumb presses push top.

Specifically, being scooped in described with outer scoop is shuttle shape structure, shuttle shape structure can subtract while guaranteed capacity Small cross-sectional area when being put into internal, avoids carrying out abdomen excessive opening, and left end uses Rouno Cormer Pregrinding Wheel, and fillet reduces insertion Resistance, while avoiding damage to tissue.

Specifically, it is described it is outer scoop, it is described in scoop, the outer tube, the push rod and the cartridge exterior polish Processing, polishing reduce resistance, prevent plowing from tissue of patient, prevent plowing from operator's hand.

Working principle: the utility model is a kind of laparoscope with taking sundries, passes through the opposite of spiral salient and spiral groove Movement, is the rotary motion of interior bar for the transform linear motion of piston, thus scooped in driving relative to scooping rotation outside, so that It inside scoops and scoops mutual fastening outside, guarantee not falling out in the extract for the process for taking out tissue, liquid during scooping out liquid Body will not spill, in use, pulling block with index finger and middle finger, thumb pushes push top, scoop rotation so that interior and scoop mutual button with interior Close, go deep into from the operation opening of abdomen it is intraperitoneal, after release by extract be scooped into it is interior scoop in, then press push top, inside scoop with Taking-up when scooping fastening outside.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
