Description
Technical field
The present invention relates to a kind of medical instrument, especially a kind of cutting tissue circular staplers.
Background technology
Existing cutting tissue is very high for the level requirement of doctor generally by the way of artificial, and long-term surgery
The burden to doctor can be increased, so need offer a kind of easy to operate, and the medical care precess instrument of precise structure.
Invention content
Goal of the invention：It is multiple it is an object of the invention to solve to need to be accomplished manually operation in present cutting tissue operation
Miscellaneous and big to the mental burden of doctor problem.
Technical solution：The present invention provides following technical scheme：A kind of cutting tissue circular staplers, including gun shaped ontology,
The gun shaped ontology includes barrel portion and handle portion, and the muzzle of barrel portion is equipped with anastomat head plate, and anastomat head plate is towards gun shaped
Ontology side center has the hollow straw extended, hollow straw tail portion to be inserted into the tissue containing cavities of barrel portion；The gun barrel
Portion is equipped with the rounded ring body for being coated on and fitting closely on the outside of barrel portion and with barrel portion close at handle portion, and rounded ring body is equipped with
Facilitate the shaft for pushing rounded ring body to be axially moved and rotate along barrel portion；Telescopic rod is fixed on rounded ring body, telescopic rod is remote
Top from barrel portion is fixed with circular cutter.
As an optimization, the telescopic rod includes at least two cracking connecting rods, has the screw hole being mutually adapted on two sections of connecting rods, makes to stretch
Contracting bar can be fixed after flexible.
As an optimization, the anastomat head plate is installed on the head of hollow straw, and anastomat head plate center, which has, can allow sky
The mounting hole that heart suction pipe exposes.
As an optimization, the tissue containing cavities are connect with negtive-pressure implement.
As an optimization, the inner surface that the rounded ring body is contacted with barrel portion is using the coating spray that can increase friction coefficient
It applies.
Operation principle：According to the tissue size cut off needed for operation, the anastomat head plate of designated diameter is chosen, then basis
The size of anastomat head plate, the length of adjustable telescopic rod so that the air line distance of circular cutter to anastomat head plate center with coincide
The radius error of device head plate is no more than 1mm, and anastomat head plate is posted by the required tissue cut off, is slowly advanced rounded ring body
On shaft make rounded ring body along barrel portion be axially moved until circular cutter resist needed for cut off tissue, be slowly advanced circle
Shaft in shape ring body makes rounded ring body be rotated along barrel portion, is cut off to tissue.
Advantageous effect：The present invention is compared with the existing technology：Since the waste motion of hand influences whether the accurate of cutting tissue
Property, and the requirement accurately performed the operation for doctor is very high, that is, allows to perform an operation, institute also very big for the mental burden of doctor
The operation of this part is converted into the operation of machinery so that mechanical feature with high accuracy obtains with design using the present invention
It plays.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
It the present invention rather than limits the scope of the invention, after having read the present invention, those skilled in the art are to of the invention each
The modification of kind equivalent form falls within the application range as defined in the appended claims.
As shown in Fig. 1, a kind of cutting tissue circular staplers, including gun shaped ontology, the gun shaped ontology includes gun barrel
The muzzle of portion 1 and handle portion 5, barrel portion 1 is equipped with anastomat head plate 2, and anastomat head plate 2 has towards gun shaped ontology side center prolongs
The hollow straw 3 of stretching, 3 tail portion of hollow straw are inserted into the tissue containing cavities 4 of barrel portion 1；The barrel portion 1 is close to handle portion
The rounded ring body 6 for being coated on 1 outside of barrel portion and being fitted closely with barrel portion 1 is equipped at 5, rounded ring body 6 is equipped with and conveniently pushes away
The shaft 9 that dynamic rounded ring body 6 is axially moved and rotates along barrel portion 1；Telescopic rod 7 is fixed on rounded ring body, telescopic rod 7 is separate
The top of barrel portion is fixed with circular cutter 8.
The telescopic rod 7 includes at least two cracking connecting rods, has the screw hole (not shown) being mutually adapted on two sections of connecting rods, makes to stretch
Contracting bar can be fixed after flexible.
The anastomat head plate 2 is installed on the head of hollow straw 3, and 2 center of anastomat head plate, which has, can allow hollow straw 3
The mounting hole of exposing.
The tissue containing cavities 4 are connect with negtive-pressure implement 10.
The inner surface that the rounded ring body 6 is contacted with barrel portion 1 is using the coating spraying that can increase friction coefficient.As gathered
Urethane non-skid coating.
According to the tissue size cut off needed for operation, the anastomat head plate 2 of designated diameter is chosen, then according to anastomat head
The size of plate 2, the length of adjustable telescopic rod 7 so that circular cutter 8 arrives the air line distance and anastomat head at 2 center of anastomat head plate
The radius error of plate 2 is no more than 1mm, and anastomat head plate 2 is posted by the required tissue cut off, is slowly advanced rounded ring body 6
On shaft 9 so that rounded ring body 6 along barrel portion 1 be axially moved until circular cutter 8 resist needed for cut off tissue, slowly pushing away
Into the shaft 9 on rounded ring body 6 so that rounded ring body 6 is rotated along barrel portion 1, tissue is cut off.
