Abstract
The invention discloses a double-end endoscope flexible pipe type sampling tongs comprising a fixed jaw; two sides of the fixed jaw are respectively provided with a movable jaw; each movable jaw forms a sampling jaw with the fixed jaw, and respectively connected with a handle propeller through a haulage cable; each handle propeller respectively control one movable jaw to move through one haulage cable. The double-end endoscope flexible pipe type sampling tongs enters the human body, and two handle propellers can respectively control two movable jaws to move, thus obtaining two living tissue sample; in a same space and time, the double-end endoscope flexible pipe type sampling tongs can provide double pathology samples, can double the verification and measurement ratio, can reduce patient pains and operation time, and has less damages on the endoscope equipment.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of double end scope hose type sample pickup tongs.
Background technology
Scope hose type living tissue sampling forceps, mainly through soft endoscopic forceps channel, is stung and is got stomach, intestinal digestive system or respiratory system biological tissue, check for pathological analysis.Concrete structure is: jaw is connected with steel wire rope by traction steel wire, and the end of steel wire rope is connected with operating grip, and the outer cover of traction steel wire and steel wire rope has sheath spring tube.But present jaw is all generally single head, can only sting at every turn and get one piece of living tissue specimen, and the inspection of the pathological analysis of routine needs more than one piece of specimen usually, therefore needs repeatedly to sample.
Summary of the invention
The object of the present invention is to provide a kind of double end scope hose type sample pickup tongs, once-through operation can obtain two pieces of living tissue specimens simultaneously.
To achieve these goals, technical scheme of the present invention is: a kind of double end scope hose type sample pickup tongs, it is characterized in that described sample pickup tongs comprises a regular jaw, described regular jaw both sides are respectively arranged with a moving jaw, each moving jaw is all combined into a pair sampling jaw with described regular jaw, each moving jaw is all connected with a handle propeller by haulage cable, and each handle propeller controls a moving jaw action respectively by a haulage cable.Described regular jaw is fixed on bearing, described two are connected by rotating shaft between moving jaw and regular jaw, the end of described two moving jaws is connected with a push-pull bar respectively by a connecting rod piece, described push-pull bar is connected with haulage cable, be between described connecting rod piece and push-pull bar and moving jaw and be rotationally connected, the haulage cable be connected with described two moving jaws is all positioned at a bourdon tube, and described bourdon tube is fixedly connected with bearing.
Being provided with locking device in each handle propeller, so that by being locked after a moving jaw sampling, and then being sampled by another moving jaw.
The both sides that are fixed on of described regular jaw are provided with the inner concave corresponding with both sides moving jaw, and described regular jaw and the first sampling jaw and the second sampling jaw are also provided with bakie or small opening.
Double end scope hose type sample pickup tongs of the present invention is once stretching into after in body, can by the action respectively of two handle propeller controls, two moving jaws, obtain two pieces of living tissue specimens simultaneously, in same room and time, many one times of the Pathologic specimen provided, verification and measurement ratio doubles, and can reduce patient's misery and operating time, the loss of endoscope equipment is less.

Fig. 2 is the partial enlarged drawing at jaw position in Fig. 1.
Fig. 3 is another using state figure at jaw position.
Fig. 4 is the structural representation of handle propeller locking device.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, a kind of double end scope hose type sample pickup tongs, it is characterized in that described sample pickup tongs comprises a regular jaw 1, described regular jaw is fixing on mount 18, described regular jaw both sides are respectively arranged with the first moving jaw 2 and the second moving jaw 3, first moving jaw, second moving jaw and regular jaw are all connected by a rotating shaft, first moving jaw and described regular jaw are combined into a pair sampling jaw, second moving jaw and described regular jaw are also combined into a pair sampling jaw, the end of the first moving jaw is connected with the first push-pull bar 5 by first connecting rod sheet 4, be between described first connecting rod sheet 4 and the first push-pull bar 5 and the first moving jaw 2 and be rotationally connected, described first push-pull bar 5 is connected with first handle propeller 7 by the first haulage cable 6, the end of the second moving jaw is connected with the second push-pull bar by second connecting rod sheet, be between described second connecting rod sheet and the second push-pull bar and the second moving jaw and be rotationally connected, described second push-pull bar is connected with second handle propeller 9 by the second haulage cable 8, namely each handle propeller controls a moving jaw action respectively by a haulage cable.First haulage cable and the second haulage cable are all positioned at bourdon tube 10.
Described sample pickup tongs also comprises one handle mobile jib 11 as shown in Figure 4, handle mobile jib 11 is fixedly connected with one end of bourdon tube 10, the other end of bourdon tube 10 is then fixedly connected with support 18, described handle propeller 13 is arranged on the both sides of handle mobile jib 11, the mobile jib chute 12 matched with handle mobile jib is provided with in handle propeller 13, can slide along handle mobile jib, a limited block chute 14 is also provided with in handle propeller 13, described limited block chute 14 is vertical with mobile jib chute 12 to be arranged, a spring 15 is provided with in limited block chute, spring outwards is provided with a limited block 16, handle mobile jib is provided with the stopper slot 19 matched with described limited block, when handle propeller slides along handle mobile jib, spring keeps confined state, when the angle of rake limited block of handle moves to the stopper slot of handle mobile jib, under the effect of spring-return power, limited block enters in stopper slot, handle propeller is locked, the position of moving jaw is also locked simultaneously.Described limited block is also provided with a driving lever 17, when needs unlock, stirs driving lever, make limited block be retracted in stopper slot, then handle pusher is unlocked.
During use, driven forward first handle propeller 7, the first push-pull bar 5 is driven to travel forward by the first haulage cable 6, be rotationally connected because first connecting rod sheet 4 and the first push-pull bar 5 and the first moving jaw 2 are, first moving jaw 2 is connected with regular jaw 1 by rotating shaft again, and therefore the first moving jaw 2 is opened.By driven forward second handle propeller, the second moving jaw is opened equally.Then, after first sampling jaw is aimed at sampling point, promote first handle propeller backward, then the first push-pull bar is driven to move backward by the first haulage cable, drive the first moving jaw closed to regular jaw direction, namely the first sampling jaw closes, and is successfully completed the sampling of first piece of biological tissue, now the angle of rake limited block of first handle enters in stopper slot, by the first sampling jaw locking.The sampling the second sampling jaw being completed second piece of biological tissue can be operated equally.
In order to complete sampling better, towards the first sampling jaw and the second sampling jaw direction, all inner concave is set at regular jaw, many biological tissues are got can clamp, clamp blood residual on the biological tissue got to bleed off, described regular jaw and the first moving jaw and the second moving jaw are also provided with bakie or small opening.
