Abstract
The invention discloses it is a kind of can continuous sampling biopsy forceps, belong to area of medical devices, can sampling when continuous sampling.
Description
Technical field
The present invention relates to area of medical devices, a kind of specifically biopsy forceps.
Background technology
Biopsy forceps is that endoscopy takes the indispensable instrument of Pathologic specimen, and in order to prevent infecting, biopsy forceps is typically one
What secondary property used, and existing biopsy forceps is typically only capable to disposably take a sample, but result in the need for when need to take multiple samples
Change biopsy forceps or taken out out of human body, cost is high, patient suffering.
Application number 201610176557.X, the Chinese invention patent of entitled continuous sampling biopsy forceps disclose a kind of connect
Continuous sampling biopsy forceps, including binding clip support and two binding clips.Wherein, two binding clips are hinged on pincers by independent connecting pole respectively
The inner side of head bracket front end, so as to form the space for accommodating multiple samples between two binding clips；Also, by binding clip branch
The sampling probe extended between oriented two binding clips is set on the platform of frame, multiple samples that continuous sampling obtains can be caused to take
It is arranged in order on sample pin.These existing more sub-sampling biopsy forceps when actual use, it is necessary to after the sample that takes toward pusher
Before the sample that takes, but when sample, binding clip closes, it is difficult to by postponing for preceding sampling, cause actual use when
Wait, multiple sampling operation is difficult, it is preceding take can sometimes fall down, after take be difficult to push away before take.
The content of the invention
The present invention in order to solve prior art when present in problem, disclose it is a kind of can continuous sampling biopsy forceps, bag
Binding clip, connecting tube, handle and sliding block are included, binding clip and handle are located at the both ends of connecting tube, are provided with sampling probe in binding clip, sliding block is located at
In connecting tube, it is characterised in that described binding clip includes the first binding clip and the second binding clip, and binding clip is provided with articulated joint, the first binding clip
The front end of articulated joint is hinged on the second binding clip, the center of articulated joint is provided with the fixing device that sampling probe is fixed, described
Fixing device be provided with and be used for the passage that passes through of sampling probe, the end of the first binding clip and the second binding clip is connected with control binding clip and opened
The connecting line closed, fixing device are provided with the active tunnel for being used for connecting line activity, and the end of the sampling probe is connected with control
The sampling needlework that sampling probe is retreated, described handle is interior to be provided with button, and button is provided with a convex portion, and convex portion is deep into connecting tube
Interior, button and connecting tube are provided with back-moving spring；
Sliding block includes the first sliding block and the second sliding block, and the first sliding block and the second sliding block control two centers in connecting tube respectively
Portion, connected by sliding block spring between two central parts.
When in use, the convex portion of button is generally 1 cm, is deep into connecting tube or corresponding end,
Due to the effect of spring, button is typically that can not promote what sampling probe advanced, but when button is pressed with hand, can with gram
The power of spring is taken, promotes sampling probe to advance.
The operation principle of sliding block is as follows, and the first sliding block controls the central part of the first sliding block, the generally tubular surface in handle
Provided with transportable conduit, the first sliding block is connected by attachment means with central part, and for attachment means by conduit, this part can
To use existing technology, difference with the prior art is, provided with two sliding blocks, the central part of two sliding blocks is provided with spring,
Two sliding blocks connect only by spring, that is, outside pipe are unconnected.When two sliding blocks are in contact, at spring
In stretched condition, at this time the power suffered by spring is F, and the intermolecular forces of two sliding blocks are also F, when with the sliding block of hand post-tensioning second
When, at first, two binding clips control the line of binding clip opening and closing from contact is reached（Hereinafter referred to as binding clip line）The tension force being subject to
It is smaller, contacted when binding clip is opened and closed, the tension force of binding clip line can increase suddenly, reach F（F technical staff is opened and closed power test according to binding clip
Output control）, at this time, two sliding blocks will start to do the motion of a phase separation, and the second sliding block continues to move backward, the
One sliding block will stop or move slowly, so ensure that binding clip will not close too tight.But in actual use
When be according to following procedure operation：
Step 1：Biopsy forceps is goed deep into the human body, being sampled position with sampling probe fixes, with the sliding block of hand post-tensioning first, directly
To tightly closing；
Step 2：After tightly closing, fix the second sliding block with hand, unclamp the first sliding block, the first sliding block can reset, when resetting to two
When the chucking power of individual binding clip is less, stop resetting.Can is by two binding clip controls in opening and closing when chucking power is not too tight again
But the state of sampling tissue can be fixed；
Step 3：Button is pressed with finger, because binding clip opening and closing is not tight, sampling probe can relative sampling tissue advance；
Step 4：It will be pushed away before second sliding block, binding clip opening and closing, slow release button, sampling probe resets, and the tissue of sampling will be fixed
Sampling probe relatively after position；
Step 5, repeat the above steps, you can completion once takes multiple tissue samples.
As an improvement, the first described binding clip and the second binding clip are provided with by pin-hinges in articulated joint, among pin
Fixed sampling probe and the through hole passed through for sampling probe, in this case, can avoid setting on articulated column by unnecessary limit
Position device, reaches that sampling probe is unswerving to move forward and backward.
As an improvement, with the connecting line that the first binding clip and the second binding clip are connected respectively by connector set, in connector
Between be provided be used for sample the through hole that needlework or sampling probe pass through.
As an improvement, described sampling probe is provided with the limited post that limitation sampling probe transition retreats, so designing can be to prevent
The only retrogressing of imprudence sampling probe, the cooperation of limited post and push-button reset spring can cause sampling probe advance in fixed position and
Retreat, further complete sampling operation.
As an improvement, described the first binding clip and the second binding clip is respectively equipped with positioned at the conduit for placing sampling probe, when first
When binding clip and the second binding clip close, sampling probe is in the passage of two conduit synthesis, and energy forward-reverse, this to set
Meter, it is ensured that in the case where tissue does not move, sampling probe reach is further preferably complete the tissue of sampling toward pusher
Into more sub-samplings, the wherein design of conduit designs according to the cross-sectional sizes of sampling probe, slightly larger than the section of sampling probe.
The beneficial effects of the present invention are：The present invention makes binding clip reach closure by controlling the elasticity that binding clip is opened and closed
Optimum state, and then control the advance of sampling probe so that the tissue of sampling retreats, and reaches accurate more sub-samplings, can be in work
An inspection human body of pincers, completes more sub-samplings, reduces cost and the pain of patient.
