Background technique

During the operation of various surgicals, bleeding etc. usually influences the sight of doctor, so that the standard of surgical procedure True property is affected, in addition, can also be mingled with the solid matters such as the clast of some tissues in oozing of blood.In general, hand is handled Art hydrops uses aspirator, is that aspirator generally comprises suction device and suction aspirator tip, and wherein suction device provides imbibition Gravitation, and suction aspirator tip be usually it is hollow, one end is the blank pipe that can suck hydrops, and the other end is and suction device The interconnecting piece being connected, hydrops enter suction aspirator tip from blank pipe end and enter attraction by the entire hollow portion of suction aspirator tip In device.When doctor uses suction aspirator tip, suction aspirator tip is regular length, and the deep mixed doctor of patient affected part is difficult once to slap Hold suction aspirator tip length, it is often necessary to which doctor could grasp depth in the multiple test depth of patient affected part, come to doctor's work belt Trouble and raising patient vitals are dangerous, a kind of novel cranial surgery screw telescopic formula as disclosed in Chinese patent CN203842082U Suction aspirator tip, the program when in use, are clamped below control handle with index finger and middle finger first, then use thumb wheel rotator It moves up and down external screw thread in control handle, while can be adjusted up and down in height telescopic mast in control handle, simultaneous retractable head It is moved up and down in control handle, control knob use is pinned after adjusting, but the program only has simply flexible function Can, it not can guarantee the sealing effect between supervisor and suction pipe liquid pipe after flexible, thus not to aspirator use process bring Just.

Utility model content

The purpose of this utility model is to provide a kind of novel cranial surgery screw telescopic formula check devices, have to suction The suction aspirator tip of lead device increases screw-type Telescopic, and ensure that the advantages of stretching rear suction aspirator tip leakproofness, solves When doctor uses suction aspirator tip, suction aspirator tip is regular length, and patient affected part deep mixed doctor, which is difficult once to grasp, to be attracted Device head length, it is often necessary to doctor could grasp depth in the multiple test depth of patient affected part, to doctor work make troubles and Improve the problem of patient vitals' danger.

To achieve the above object, the utility model provides the following technical solutions: a kind of novel cranial surgery screw telescopic formula Check device, including supervisor and suction pipe liquid pipe, the suction pipe liquid pipe are movably connected in the tube wall of supervisor, the pipe arm of the supervisor Annular groove is offered, described to be responsible for the inner ring that bearing is fixedly connected with by annular groove, the outer ring of the bearing is fixed to be connected It is connected to spill spin block, the spill spin block is rotatablely connected by annular groove and supervisor, and the side of the spill spin block is fixedly connected with interior Screwed pipe, the pipe arm of supervisor offer sleeve mounting groove, and the supervisor is fixedly connected with sleeve, the set by sleeve mounting groove Inner wall in cylinder cylinder is connected with fixed block, and the side of the fixed block is fixedly connected with telescopic rod.

The pipe arm of the suction pipe liquid pipe is fixedly connected with sealing ring, and the side of the sealing ring is fixedly connected with external screw thread Pipe, the external screw thread face of the male-pipe are threadedly coupled with the inner threaded surface of riffled tube, and the side of the telescopic rod passes through set The nozzle of cylinder is simultaneously fixedly connected with the side of sealing ring.

Preferably, the side of the suction pipe liquid pipe is fixedly connected with guide pipe, pipe arm of the guide pipe close to its both ends It is fixedly connected to limited block.

Preferably, the block wall of the limited block offers ball mounting groove, and the limited block passes through the activity of ball mounting groove It is connected with ball, the arc surface of the ball is flexibly connected with the inside pipe wall of supervisor.

Preferably, the side of the limited block is fixedly connected with reset spring, and the reset spring socket is in guide pipe Outside pipe arm.

Preferably, the side of the reset spring is fixedly connected with compression ring, and the compression ring is socketed in the pipe of guide pipe Outside arm.

Preferably, the pipe arm of the guide pipe is socketed with sealing rubber ring, and the sealing rubber ring is movably connected in compression Between ring.

Compared with prior art, the beneficial effects of the utility model are as follows:

One, the utility model is revolved by bearing, spill spin block, screwed pipe, sealing ring and the male-pipe of setting by rotation Switch block, so that riffled tube that its side is fixedly connected while being rotated, by the rotation of riffled tube, to drive outer spiral shell The contraction of line pipe and process is stretched out, at this point, since male-pipe and suction pipe liquid pipe are connected as the effect of an entirety by sealing ring, So that suction pipe liquid pipe can follow the movement of male-pipe and move, and then by the contraction of male-pipe and stretch out process, thus Suction pipe liquid pipe is controlled to shrink and extend.

Two, the utility model passes through sleeve, fixed block and the telescopic rod of setting, by telescopic rod along sleeve

It stretches, provides support and the effect of guiding for the contraction and stretching of male-pipe.

Three, guide pipe, limited block, ball, reset spring, compression ring, sealing rubber ring of the utility model by setting, It is rolled by inner wall of the ball in supervisor's pipe, reduces guide pipe pipe outer arm and the friction being responsible between the inner wall in pipe hinders Power, so that the telescopic process of suction pipe liquid pipe is more smooth, sealing rubber ring is close to playing between suction pipe liquid pipe and supervisor The effect of envelope, reset spring provide restoring force for the movement of compression ring so that sealing rubber ring along supervisor inside pipe wall move when, Certain buffer function is played, sealing rubber ring influence by frictional resistance for a long time is avoided, during this, two compression rings begin Final pressure tightly lives sealing rubber ring, avoids sealing rubber ring because the frictional resistance for moving generation along supervisor's inside pipe wall is excessive, causes close Sealing rubber ring, there is a phenomenon where be broken.

In conclusion increase screw-type Telescopic to the suction aspirator tip of aspirator, and ensure that it is flexible after attract The leakproofness of device head, solving the suction aspirator tip when doctor is using suction aspirator tip is regular length, the deep mixed doctor of patient affected part Life is difficult once to grasp suction aspirator tip length, it is often necessary to which doctor could grasp depth in the multiple test depth of patient affected part, give Doctor, which works, makes troubles and improves the problem of patient vitals' danger.
