Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a disposable single-channel multi-hole puncture outfit.

Background

The laparoscope puncture outfit provides an instrument channel application range for abdominal cavity pelvic cavity minimally invasive surgery, can be used for various minimally invasive surgical operations, has a holding handle which accords with the human engineering principle, has comfortable hand feeling and excellent puncture controllability, and has satisfactory puncture effect due to a through blade manufactured by fine work;

the porous puncture ware of disposable single channel exists when using, and the too big not accurate enough that leads to the puncture of action during the operation puncture, the inconvenient problem of carrying out little amplitude adjustment puncture ware, for this reason we provide a porous puncture ware of disposable single channel.

Disclosure of Invention

The invention aims to provide a disposable single-channel multi-hole puncture outfit, which solves the problems that the disposable single-channel multi-hole puncture outfit proposed in the background art is used, too large action is caused during puncture operation, so that the puncture outfit is not accurate enough, and is inconvenient to adjust in a small range.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a porous puncture ware of disposable single channel, includes head of a ware, sleeve pipe, puncture tube, the outside of head of a ware is equipped with solid fixed ring, firm ring is located solid fixed ring's upside, gu the symmetry is equipped with the slider on the fixed ring, be equipped with on the slider and hold between the fingers the pole, be equipped with the second ring gear on the firm ring, gu fixed ring's top is equipped with the connecting rod, the top of connecting rod is equipped with first ring gear.

Preferably, an annular sliding groove is formed in the middle of the outer side surface of the fixing ring, the sliding block is located in the sliding groove, and the sliding block is connected with the fixing ring in a sliding mode.

Preferably, the one end of the pinching rod is connected with the sliding block, the other end of the pinching rod is in a semi-circular ring shape, and a diagonal line is arranged on the surface of the semi-circular ring of the pinching rod.

Preferably, the connecting rod bottom is connected and first ring gear is connected with the connecting rod rotation with the top of solid fixed ring, first ring gear is the same with two distances of holding between the fingers the pole and keeping away from solid fixed ring tip.

Preferably, the middle position of the outer side surface of the stabilizing ring is provided with a ring groove, the second gear ring is positioned in the ring groove, and the annular outer surface of the second gear ring is provided with a tooth groove.

Preferably, teeth are arranged on the outer surface of the first gear ring in an annular shape, the first gear ring is connected with the second gear ring in a staggered mode, and when the first gear ring rotates in the counterclockwise direction from left to right, the second gear ring rotates in the clockwise direction from left to right.

Preferably, the annular groove has been seted up to the inside that the sleeve pipe is close to the ware head end, the outside that the puncture tube is close to the ware head end is equipped with the rubber buffer, the rubber buffer is located the annular groove, the rubber buffer outside is equipped with semicircular arch, the opposite internal surface of sleeve pipe and rubber buffer is equipped with semicircular recess, the arch matches with the recess.

Compared with the prior art, the invention has the beneficial effects that:

1. through the first ring gear, the second ring gear of design, hold between the fingers the pole, gu fixed ring, the thumb effect drives the second ring gear rotatory at first ring gear and first ring gear, simple and convenient, nimble carry out the rotation of small action with the puncture ware, the position of having adjusted the puncture ware of easy and simple to handle, it is accurate inadequately to move too big puncture that leads to when avoiding operating the puncture.

2. Through the rubber buffer of design, arch, the arch in the rubber buffer outside is inseparable with the laminating of sleeve pipe internal surface, and the leakproofness is high between sleeve pipe, the puncture pipe, has improved the gas tightness of puncture ware, has guaranteed the stability of atmospheric pressure, prevents that gas leakage.
