A kind of scalp clip output deviceTechnical field
The invention belongs to medical instruments field, more particularly, to a kind of scalp clip output device.
Background technology
In existing medical technology, when cerebral surgery operation is carried out, it is necessary to be fixed using substantial amounts of scalp clamperThe scalp that patient is cut open, and scalp is stopped blooding, an operations on cranium and brain will use multiple scalp clips, traditional operation simultaneouslyWhen scalp clip is fixed on scalp clip applying forceps by nurse, pass to operative doctor, after operative doctor is finished, empty pliers is given backNurse takes another scalp clip applying forceps again, and such doctor needs to repeat to connect to pass scalp clip applying forceps, wastes time and energy, and nurse is in once performing the operationSubstantial amounts of scalp clip is transmitted, labour intensity is big, and the amount of bleeding of patient will be increased, extend operating time, increased handArt and the risk of patient.
Application No. CN201010208612.1 discloses a kind of scalp clip gun, including housing with handle, oneFor deposit the squeeze of scalp clip, one send folder forward push away clamp mechanism and a clamp mechanism for promoting scalp clip to open；InstituteState and be provided with housing storehouse casket, in the top of handle, squeeze snaps in storehouse casket to storehouse casket；The squeeze include sliding sleeve, clamp holder andElastic card；One side of the sliding sleeve has been equidistantly positioned multiple holes, the clamp holder bag in the length direction of sliding sleeveInclude upper side, downside, bottom surface and go out the cell body long of jaws, U-shaped profile, the bottom surface of clamp holder along cell body long lengthDirection has been equidistantly positioned multiple holes, and be provided with to drive cell body movement long on the outside of a side of clamp holder pulls button,Clamp holder inserts sliding sleeve, and there is a hole side opening of clamp holder towards sliding sleeve in sliding sleeve, the elastic card have two toThe angular flexibility of outer protrusion, elastic card is arranged in the U-lag of clamp holder, and two angular flexibilities are respectively clamped into the sliding sleeve on elastic cardIn the hole set on cylinder and in the hole of clamp holder bottom surface；The clamp mechanism that pushes away includes trigger, and it is another that trigger one end is referred to as trigger headEnd is referred to as trigger tail, and trigger is rotated by the pivot pin set between trigger head and trigger tail and is fixed on housing, the insertion of trigger headButton is pulled on clamp holder, the trigger connects a spring, and spring band trigger action head swings after keeping clamp holder movement and returns to originalBeginning position, described clamp mechanism include seesaw, and seesaw is rotated by pivot pin and is fixed on housing, and one end of seesaw is to openThe lower mouth of mouth folder, mouth is arranged on the downside that housing clamp holder goes out jaws present position under the folder of opening, and the other end of seesaw is connected toTrigger tail, it is suitable for reading that housing goes out on the upside of jaws present position to be provided with opening folder in clamp holder.Although the scalp clip gun can be evenContinuous submitting scalp clip clamps scalp, but the scalp clip for being used can not be removed quickly, and holding area is unfavorable for behaviourMake the operation of personnel, structure is more complicated, poor reliability, maintenance and cleaning are more inconvenient.
The content of the invention
The purpose of the present invention is to propose to a kind of scalp clip output device, the scalp clip output device is conveyed using cartridge clip modeScalp clip, that is, facilitate health again, and simple structure, clamping is rapid, using split-type design, repairs and easy to clean, improves handArt efficiency, reduces the operation risk of patient.
The technical solution adopted by the present invention is as follows：A kind of scalp clip output device, including button, handle, push toward reassemblingPut, thorax body, one-way pushing squeeze and retaining bar, described taper knob is located at the left end of thorax external body, and handle is detachable with thorax bodyIt is fixedly connected, the bottom of the handle is provided with button hole, and button is installed in button hole, described button is by pushing past reassemblingPut and be connected with one-way pushing squeeze, push reciprocating apparatus control one-way pushing squeeze pushes away folder and homing action, and one-way pushing squeeze is located atThe inside of thorax body, the inside of one-way pushing squeeze is provided with multiple scalp clips, and the inside upper and lower surface of one-way pushing squeeze is provided withMultiple drives the unidirectional elastic bumps that scalp clip travels forward, one-way pushing squeeze to be resetted after scalp clip is released, one-way pushing squeezeInside both sides be symmetrically arranged with prevent scalp clip retreat retaining bar, the retaining bar is detachable with thorax body to be fixedly connected,The front end of the thorax body is provided with necking inclined-plane, and the front end of one-way pushing squeeze is provided with the clip assembly for opening scalp clip, instituteThe front end inside left and right sides for stating thorax body is provided with retaining extension bar, and scalp clip is in a clip assembly and the common work of retaining extension barUnder, corresponding site is opened and clamped.Button and handle are equipped with, advantageously in the gripping of operator, one-way pushing squeezeScalp clip is released into thorax body, in the one-way pushing squeeze under the collective effect of unidirectional elastic bumps and retaining bar, scalp clip can only courtThe exit movement of thorax body, because the front end of thorax body is provided with necking inclined-plane, after scalp clip is released thorax body by one-way pushing squeeze,During one-way pushing squeeze resets, a clip assembly retracts, and due to the effect on necking inclined-plane, a clip assembly beats scalp clipOpen, after scalp clip clamps corresponding site, scalp clip is released a clip assembly by retaining extension bar, and then clamps scalp corresponding site.
