Description
Technical field
This utility model relates to the hemostatic clamp that a kind of Microendoscopic is used.
Background technology
Endoscope occurred over more than 50 year, had experienced the stage from the medical diagnosis on disease to the disease treatment, and is very effective and reliable to the treatment of some diseases.Biological stomach, intestinal often can cause institute hemorrhage because of damage behind various diseases or accidental injury or the therapeutic endoscopy; generally carry out herbal sprinkling for active hemorrhage, the methods such as high-frequency electrical, laser, argon calcination petechia method, the hemostasis by compression of hemostatic clamp handset tool are treated.Wherein the hemostasis by compression of hemostatic clamp handset tool is the reliable approval that has also obtained doctor and patient for the active hemorrhage therapeutic effect that Non-Variceal causes; Hemostatic clamp also can promote its wound healing to the closure that gastral mucosa injury carries out to a certain degree, also can the little fistula mouth of closed digestive tract, avoid abdominal.
Seen hemostatic clamp roughly has 3 kinds clinically:
A kind of is clip and the hemostatic clamp that installs separate type, clip is disposable use, clip can not repeat folding, device is for reusing, whenever dischargeing a clip doctor scene assembles clip and device, and can not repeat folding from new location, operation is trouble comparatively, just can't open in case clip is closed, discharge mistake and also need change other apparatuses it is pulled out, again make clip, about 10 ~ the 12mm of length after clip discharges, installing every operation once needs the device disinfection, if sterilize the bad risk that has infection, but device is without protecting pipe;
The second clip and device one but can not repeat folding, just can't open in case clip the same as the first is closed, discharge wrong also need to change other apparatuses it is pulled out, assembled clip again making clip but need not, its outside of the about 10 ~ 12mm of length was provided with a protecting pipe after clip discharged, and also comparatively bothered because increased protecting pipe during operation.
The third can repeat the folding outside and be provided with a trocar sheath, but its preliminary closure is observed the clip position that whether needs, more front two kinds of advanced persons, the rear about 15.5mm of clip length grows the projection that its afterbody has thorn-like but it is because structure problem discharges, be not suitable for the release in the small spaces such as esophagus, have the risk that causes Alimentary Tract Perforation, the outside is also overlapped has the protecting pipe operation not too convenient.
The utility model content
For overcoming the above-mentioned shortcoming of prior art, it is a kind of simple in structure that this utility model provides, the easy to operate hemostatic clamp that can repeat folding with pusher.
Can repeat the hemostatic clamp of folding with pusher, comprise handle, be slidably mounted on the slip handle on the handle, the control steel wire that near-end and slip handle are fixing and the chuck that is connected with control steel wire far-end, and insert gastral sheath pipe; The control steel wire is socketed in the sheath pipe, is socketed with bourdon tube between sheath pipe and the control steel wire;
It is characterized in that: chuck comprises a pair of intermediate plate, takes in the containing tube and the expansion pin that is fixed in containing tube of intermediate plate, and expansion pin is between two intermediate plates; Intermediate plate comprises kink and the alar part of chuck, arc, and chuck is positioned at the far-end of kink, and alar part protrudes from the projection into the kink near-end, and the overbending direction of the kink of two intermediate plates is opposite, thus make hemostatic clamp in use intermediate plate mutually open;
The far-end of control steel wire is fixed with the connection end that connects two intermediate plates, connection end comprises and control the fixation with steel wire steel wire end that is connected and the eseparation ring that is connected with intermediate plate, steel wire end is fixedly connected with eseparation ring, eseparation ring is survivor of a murder attempt's circle, two terminations of eseparation ring are mutually folding, and two intermediate plates all seal in the eseparation ring;
Be fixed with the connector that is connected with the containing tube detached type on the bourdon tube, connector comprises the ring body that is fixedly connected with bourdon tube, be distributed with equably elastic card claw on the circumference of ring body, gapped between the elastic card claw, the far-end of elastic card claw is provided with the flange that extends internally, and containing tube is provided with and allows flange to snap in its interior scrobicular ring;
Steel wire end comprises the shank and the expansion-head that is connected eseparation ring of fixing control steel wire, and in the shank socket and connector of steel wire end, expansion-head exposes to connector and greater than the connector inner chamber, the contact surface of expansion-head and connector is taper seat.
Further, the claw of connector is provided with the boss that extends internally, and boss pushing tow containing tube is to distal movement.
Further, each claw all offers through hole, is equipped with the elastic ring that prevents that claw from scattering naturally in the through hole, and elastic ring is survivor of a murder attempt's ring.
Further, the middle part of the expansion-head of steel wire end is provided with step, and step is provided with the connecting through hole that connects eseparation ring.
Further, eseparation ring is rectangular loop, and eseparation ring has mutually folding the first flanging and the second flanging.
