Description
Technical field
The invention belongs to technical field of medical equipment, it is particularly a kind of suitable for laparoscopic surgery, easy to operation use
Circular staplers under laparoscope.
Background technology
Stapler is that is medically used substitute the Medical Devices of traditional-handwork suture, have easy to use, suture is quick,
Suture tight, elastic moderate, the advantages of side effect and postoperative complication are few.Circular staplers be to the physiological tissues such as alimentary canal into
A kind of stapler being commonly used during row surgical operation is used and is axially coincide, and portion forms circular anastomosis ring within the organization, postoperative
Tissue easily healing, mitigates patient suffering.
For current circular staplers using the composite structure of resist-nailed seat and stapler device body, device body size is larger, is suitble to
It is used under conventional open surgery environment.Laparoscopic surgery is future medicine operation development as emerging Minimally Invasive Surgery
Inexorable trend.But laparoscope generally about 10mm, the large-sized circular staplers used at present can not be suitable for laparoscope hand
Art.
Invention content
The purpose of the present invention is being directed to existing circular staplers not being suitable for the shortcoming of laparoscopic surgery, one is provided
The suitable laparoscopic surgery of kind uses, circular staplers under unobscured laparoscope.
The purpose of the present invention can be realized by following technical proposal：Circular staplers under a kind of laparoscope, the laparoscope
Lower circular staplers include resist-nailed seat, cut kiss component and control stick, and control stick size is less than the size of laparoscope, can be through abdominal cavity
Mirror is inserted into the patient to be operated, and resist-nailed seat is equipped with connector, and connector is connect across kiss component is cut with control stick, cuts kiss
Component is connect with control stick, is cut kiss component and is included nail bin, pushing slice of nail and housing, the head of pushing slice of nail is equipped with cutter, and cutter is fixed
On pushing slice of nail, nail bin is fixedly connected with the casing, and pushing slice of nail can be moved with slice under the driving on control stick to resist-nailed seat direction
Dynamic to stretch out, wherein cutter cuts destination organization, and pushing slice of nail pushes against the suturing nail in nail bin to resist-nailed seat end face, suture
Nail sutures tissue.
Under the laparoscope in circular staplers, the control stick includes shell, axostylus axostyle, axle sleeve, handle, shifting block
And connector sleeve, axostylus axostyle, axle sleeve and shifting block are set inside the shell, the tail end of shell is equipped with rotatable positioning knob, one end of axostylus axostyle
It is connect with positioning knob thread, the other end of axostylus axostyle stretches out shell and connect with the connector on resist-nailed seat, is rotated by different directions
Positioning knob can adjust the length of axostylus axostyle external part, and kiss is cut between kiss component and resist-nailed seat to adjust to cut according to surgery situation
Distance；Axle sleeve is set in the outside of axostylus axostyle, and one end and the shifting block of axle sleeve are clamped, and the other end of axle sleeve is connect with connector sleeve, cuts kiss
Component is connected on connector sleeve, and wherein connector sleeve is connected together with pushing slice of nail；Shifting block is located on handle, and handle hinge is connected to
Shell, handle be equipped with resetting spring, handle be closed after under action of reset spring self-return, handle rotation drive shifting block turn
Dynamic, shifting block pushes axle sleeve and connector sleeve movement, pushing slice of nail to be pushed out housing, and cutter thereon cuts destination organization, pushes away
Nail piece pushes against the suturing nail in nail bin to resist-nailed seat end face, and suturing nail will be organized to suture；Kiss component suit will be first cut during use
On resist-nailed seat and patient's body suture site is put into togerther, control stick deeply and with the connector of resist-nailed seat connects through laparoscope
It connecing, turn positioning knob adjusts the extension elongation of axostylus axostyle, to adjust resist-nailed seat and cut between kiss component to appropriate suture distance,
Tissue to be stapled is positioned at resist-nailed seat and between cutting kiss component, and closed handle drives shifting block rotation, and shifting block pushes axle sleeve, passes through drive
Pushing slice of nail and cutter are released housing by the dynamic connector sleeve being connect with axle sleeve, realize cutting and suture, and the elastic force of resetting spring drives
Handle and shifting block return, axle sleeve are retreated with connector sleeve, and pushing slice of nail is withdrawn with cutter in housing.
Under the laparoscope in circular staplers, the positioning knob is equipped with thread groove, and thread groove one end is inserted
Enter in shell, one end of axostylus axostyle and positioning knobs fit is equipped with screw thread, and axostylus axostyle is inserted into thread groove, and rotation positioning knob is adjusted
Axostylus axostyle is inserted into the distance of thread groove, adjusts the length of axostylus axostyle, and kiss the distance between component and resist-nailed seat adjustment is cut in realization.
Under the laparoscope in circular staplers, the axostylus axostyle and the outside of positioning knobs fit one end are equipped with limit
Position device, the limiting device include banking stop and spring, and banking stop is located on axostylus axostyle, and spring is located at banking stop and thread groove
Between, it prevents axostylus axostyle from withdrawing thread groove and lead to cut kiss component too much and squeezes to resist-nailed seat, cause tissue injury.
Under the laparoscope in circular staplers, the handle is equipped with safety device, prevents from accidentally touching in operation
The damage that handle accident zonula occludens is caused removes safety device before suture.
Under laparoscope of the present invention circular staplers using resist-nailed seat, cut kiss component, control stick be separately set, assemble after use
Structure, make control stick size substantially reduce suitable for Minimally Invasive Surgery use, can be easily accessible by Minimally Invasive Surgery
Laparoscope enters patient's body, carries out suture cutting to destination organization after cutting kiss component, resist-nailed seat assembling with what is be pre-placed, makes
With conveniently；Furthermore, it is possible to according to suture size, various sizes of cut is selected to kiss component and resist-nailed seat, it is easy to change, have
Universality.
