Abstract
The utility model discloses a disposable tubular stapler which comprises a full-length whole main body, one end of which is a connecting pipe and the other end is a hollow fixing handle; the front end of the connecting pipe is provided with an osculating subassembly and a pin propping holder, and the rear end of the connecting pipe is provided with a hollow fixing handle which is provided with an adjusting nut for pulling the pin propping holder and a firing handle for driving the osculating subassembly to work; the insides of the connecting pipe and the fixing handle are provided with screw mandrel assemblies for connecting the adjusting nut and the pin propping holder, as well as the firing handle and the osculating subassembly. The stapler has the advantages that the structure is simple and reasonable, the main body is not easy to rupture, the cost is low, and the stapler is a medical instrument which is very suitable for disposable use.
Description
Technical field
This utility model belongs to medical instruments field, the one-shot tube type anastomat that particularly uses in the medical apparatus and instruments surgical operation.
Background technology
In medical science applied surgical operation, anastomat as medical apparatus and instruments, a kind of medical apparatus and instruments is absolutely necessary, interrelated data report: " high-quality anastomosis; be one of decision surgical operation key of success ", and the anastomosis success or not has closely-related the contact with employed anastomat again.At present, one-shot tube type anastomat of the prior art comprises connection tube, is provided with anastomosis cut component and nail supporting base at the connection tube front end, and the connection tube rear end is provided with hollow handle.Wherein link together by external fastening element between connection tube and the hollow handle, this connected mode not only connector is many, the processing cost height, and assembling is complicated, more has stress concentration to cause the distortion or the fracture of connector and connection tube easily.Also be to link together by external fastening element between next connection tube and the anastomosis cut component, its junction diameter is inequality, has increased frictional resistance when the when injected organism tissue of anastomat by the people, and people's when injected organism tissue is easy to generate the apparatus damage.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of simple and reasonable, with low cost, safe and reliable one-shot tube type anastomat is provided.
The purpose of this utility model is achieved in that a kind of one-shot tube type anastomat, it comprises connection tube, be provided with anastomosis cut component and nail supporting base at the connection tube front end, the connection tube rear end is provided with the hollow fixed handle, fixed handle is provided with the adjusting nut of pulling nail supporting base and promotes the firing handle of anastomosis cut component work, in the connection tube and the inside of fixed handle the screw mandrel assembly that is connected adjusting nut and nail supporting base, firing handle and anastomosis cut component is arranged, it is characterized in that fixed handle and connection tube are elongated integral bodies.
It between the fixed handle of described integral body and the connection tube the excessive structure of fairshaped circular arc.
As further improvement of the utility model, adopt between the connection pipe end of described elongated integral body and the anastomosis cut component that internal junction is box-like to be connected, its junction outer dia is identical.
Advantage of the present utility model is as follows: 1, fixed handle and connection tube are elongated integral bodies, and it can adopt model engineering plastic ABS single injection-molded, have both guaranteed the mechanical strength of apparatus, are not easy fracture, have reduced the weight of apparatus again.Especially reduce connector, simplified production process, reduced the hidden danger that causes because of operation is various.Reduce production cost, be particularly suitable for disposable needs.2, as further improvement of the utility model, adopt between its integral body and the anastomosis cut component that internal junction is box-like to be connected, its junction outer dia is identical, this connected mode good looking appearance, frictional resistance when especially having reduced the when injected organism tissue of anastomat by the people is not easy to produce the apparatus damage to people's when injected organism tissue.

Fig. 2 is the fixed handle and the connection tube joining place partial structurtes sketch map of integral body.
Fig. 3 is connection tube and anastomosis cut component joining place partial structurtes sketch map.
Among the figure: 1. nail supporting base, 2. anastomosis cut component, 3. connection tube and anastomosis cut component joining place, 4. connection tube, 5. fixed handle and connection tube joining place, 6. screw mandrel assembly, 7. fixed handle, 8. firing handle, 9. adjusting nut.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described further.
As shown in Figure 1, 2, 3, one-shot tube type anastomat, it comprises an elongated integral body with model engineering plastic ABS single injection-molded, one end of this fuselage is a connection tube 4, the other end is a hollow fixed handle 7, is the excessive structure 10 of fairshaped circular arc between fixed handle 7 and the connection tube 4, is provided with anastomosis cut component 2 and nail supporting base 1 at connection tube 4 front ends, adopt between connection tube 4 ends and the anastomosis cut component 2 that internal junction is box-like to be connected, its junction 11 outer dias are identical.The outside of fixed handle 7 is provided with firing handle 8, and firing handle 8 is connected with the workpiece of anastomosis cut component 2 with push rod in the fixed handle 7 inner screw mandrel assemblies 6 by connection tube 4.The rear portion of fixed handle 7 adjusting nut 9 arranged, adjusting nut 9 is connected with nail supporting base 1 with pull bar in the fixed handle 7 inner screw mandrel assemblies 6 by connection tube 4.
During use, rotate adjusting nut 9, by the pull bar in the screw mandrel assembly 6 nail supporting base 1 and anastomosis cut component 2 are closed to can require apart from the time, press firing handle 8, promote anastomosis cut component 2 work by the push rod in the screw mandrel assembly 6, finish and coincide and cutting action.
