Description
Technical field
This utility model belongs to field of medical device, is specifically related to a kind of sampler for digestive tract tumor biopsy.
Background technology
Clinically, in order to make a definite diagnosis the character of digestive tract tumor, biopsy sampling must be carried out, traditional way allows patient swallow air bag, and expand digestive tract, then doctor's hand-held apparatus carries out biopsy sampling, such operation is cumbersome, and doctor compares effort, and patient is also more painful.In order to address this problem, those skilled in the art have invented professional sampler, disclosed in 17 days November in 2010 of Patent Office of the People's Republic of China, Authorization Notice No. is CN201631234U, patent name is the patented technology of " sampler for digestive tract tumor biopsy ", Chinese patent on March 5th, 2013, Authorization Notice No. is CN203107168U, patent name is the patented technology of " sampler for digestive tract tumor biopsy ", above-mentioned two patented technologies are all adopt to arrange scraping blade on soft support arm, patient is without the need to swallowing air bag, direct employing scraping blade carries out biopsy sampling, although the sampler of said structure is without the need to swallowing air bag, but the scraping blade protruded, when inserting in digestive tract and extracting out, can to oral cavity, digestive tract damages, use very dangerous.
Utility model content
The purpose of this utility model is that solving prior art sampler for digestive tract tumor biopsy uses unsafe defect, a kind of sampler for digestive tract tumor biopsy is provided, its scraping blade can launch flexibly and pack up, and can not produce injury when inserting and extract out to the oral cavity of patient and digestive tract.
This utility model is achieved by the following technical solution:
I.e. a kind of sampler for digestive tract tumor biopsy, it is characterized in that comprising flexible pipe, sampling head, scraping blade controls stay cord, scraping blade controls draw ring, described flexible pipe hollow is arranged, its front end is provided with the sampling head that hollow is arranged, sampling head is the tubulose of hollow, its front end is provided with guidance spheres, the sidewall of sampling head is provided with at least 1 scraping blade, scraping blade is L-type, comprise operate portions and control part, working position is outside sampling head, controlling position is inner in sampling head, operate portions and control part junction by hinge on the sidewall of sampling head, bearing pin is set with torsion spring, during original state, the operate portions of scraping blade is in the level of expansion under torsion spring effect, scraping blade controls the flexible pipe of stay cord through hollow, the pulley that inside, sampling head front end is walked around in its inner end is connected with the control part of scraping blade, outer end and scraping blade control draw ring and are connected.
Scraping blade of the present utility model can launch and pack up in the control of stay cord, when inserting and extract out, pulls out stay cord, makes scraping blade be fitted on the sidewall of sampling head, can not produce injury to the oral cavity of patient and digestive tract.When sampling head arrives knub position, unclamp stay cord, scraping blade is Automatic-expanding under the effect of torsion spring, can carry out biopsy sampling.
The sidewall of sampling head is provided with the inner groovy mated with scraping blade.
The effect of inner groovy is: after biopsy sampling, when outwards extracting out, pulling stay cord, making scraping blade be fitted on the inwall of sampling head, the tissue of its scraping can be closed in inner groovy.
This utility model has flexible and convenient to use, safe advantage.This utility model is used to carry out digestive tract tumor biopsy sampling, safe, convenient, fast, both improve the work efficiency of doctor, additionally reduce sense of discomfort and the misery of patient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram of A portion embodiment 1 in Fig. 1;
Fig. 3 is the enlarged diagram of A portion embodiment 2 in Fig. 1.
As shown in FIG.: 1. guidance spheres; 2. sampling head; 3. scraping blade; 4. flexible pipe; 5. scraping blade controls stay cord; 6. scraping blade controls draw ring; 7. pulley; 8. bearing pin; 9. inner groovy.
Detailed description of the invention
Embodiment 1
As Fig. 1, shown in Fig. 2: the front end of flexible pipe 4 is provided with sampling head 2, sampling head 2 hollow is arranged, its front end is provided with guidance spheres 1, its interior forward end is provided with pulley 7, scraping blade 3 comprises operate portions and control part, both are hinged on by bearing pin 8 on the sidewall of sampling head 2 junction, bearing pin 8 is set with torsion spring and (is limited to visual angle in figure, do not mark), operate portions is under the effect of torsion spring, horizontal development during original state, controlling position is inner in sampling head 2, scraping blade controls stay cord 5 and enters sampling head 2 inside through flexible pipe 4, be connected with control part after walking around pulley 7, control draw ring 6 by scraping blade can control the operate portions expansion of scraping blade 3 and pack up.
When this utility model uses, when inserting, extracting sampling head 2 out, pull scraping blade to control draw ring 6, make the operate portions of scraping blade 3 be in collapsed state (being fitted on the sidewall of sampling head), can prevent the oral cavity of scraping blade 3 couples of patients and digestive tract from producing injury.When sampling head 2 arrives knub position, unclamp scraping blade and control draw ring 6, operate portions Automatic-expanding under the effect of torsion spring of scraping blade 3, can carry out biopsy sampling.
Embodiment 2
As shown in Figure 1, Figure 3: on the sidewall of sampling head 2, the place of corresponding scraping blade 3 operate portions is provided with inner groovy 9, for depositing the tissue of scraping.Other are with embodiment 1.
