As optimization, between the rounded ring body and barrel portion, there are also springs to connect, the ring of spring one end and rounded ring body Portion's connection, one end and barrel portion are connected close to one end of handle portion.
As optimization, the telescopic rod includes at least two sections of 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 optimization, the fixing axle has the support block for preventing rounded ring body from skidding off far from one end of handle portion.
As optimization, have in the fixing axle it is nested thereon and the rounded ring body that can rotate about it.
As 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 optimization, the tissue containing cavities are connect with negtive-pressure implement.
The tissue containing cavities that can block collector for cooperating with collector are equipped with as optimization, in the accommodating chamber At least two groups be respectively at the buckle of relative position in accommodating chamber.
Working 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 adjusts the length of telescopic rod so that circular cutter to anastomat head plate center linear distance and coincide The radius error of device head plate is no more than 1mm, and the tissue cut off needed for anastomat head plate is posted by detains trigger, so that ring Cutter gets at tissue and can cut off to tissue, and rotation rounded ring body completes excision operation, after the completion of excision, opens negative pressure Device, so that tissue containing cavities form negative pressure, the tissue of excision is taken in tissue containing cavities automatically by hollow straw, and operation is completed After remove collector, start to install another collector to perform the operation next time.
The utility model has the advantages that 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 To use design of the invention, by the operation of this part, mechanical operation is converted to, so that mechanical feature with high accuracy obtains It plays;If using non-removable collector, it is necessary to it carries out disinfection after each operation to collector, but due to Instrument is more accurate, may still have germ residual, seriously will lead to next the wounded's wound infection, therefore uses detachable Collector can avoid such hidden danger.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
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 the present invention has been read, 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 Portion 1 and handle portion, the muzzle of barrel portion 1 have dismountable collector for tissue collecting after the completion of cutting, and collector includes Anastomat head plate 2, hollow straw 3 and tissue containing cavities 4, anastomat head plate 2, which has towards gun shaped ontology side center, extends Hollow straw 3,3 tail portion of hollow straw are inserted into the tissue containing cavities 4 of barrel portion 1;The muzzle of the barrel portion 1, which is equipped with, to pacify Dress and the accommodating chamber 15 for accommodating collector, the barrel portion 1 have the fixing axle 5 extended, the rifle close to one end of handle portion Pipe portion 1 is equipped with rounded ring body 6 in insertion barrel portion 1 and exposed close to handle portion, and the hole of the rounded ring body 6 is covered in fixation Enable to rotate around fixing axle 5 on axis 5, is fixed with telescopic rod 7 on the part that rounded ring body 6 exposes outside, telescopic rod 7 is far from rifle The top of pipe portion 1 is fixed with circular cutter 8, and the handle portion includes shank part 9 and trigger portion 10, and trigger portion 10 passes through shank part 9 The fixed position of shaft 11, one end is exposed, and rounded ring body 6 is withstood in one end.
