The utility model has the advantages that the structure is simple, the outer appearance uses airflow design, the hand feeling of operation is good when in use, the slippage can not generate when the regulating nut is rotated, the front locking ring and the back locking ring are smoothly transitive without burrs, the operation safety is enhanced and the connection between the component and the connecting pipe can not generate circumferential rotation.

Description

Streamlined disposal tube type anastomosis

Affiliated technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of one-shot tube type anastomat that is used for the human gastrointestinal tract reconstruction operations.

Background technology

The present disposable fixed handle of anastomat that uses is column type, and firing handle is a staight shank shape, and this appearance design shortcoming is old-fashioned and inflexible ossifing, and the feel that operates is bad, is not suitable for medical worker's one-handed performance.Adjusting nut is a cylinder design, and there is fine pattern on the surface, during owing to the rotation adjusting nut, tissue must be compressed to certain thickness, in operation process, have liquid such as blood stains and be bonded at the doctor on hand, so can not produce big rotation torque, can produce skidding.Before and after clamp ring jagged overlap in pressing process exist owing to anastomat will be penetrated tissue, having overlap to exist will the scratch human organ, can damage the patient.

Summary of the invention

In order to overcome the deficiency that above-mentioned one-shot tube type anastomat exists, this utility model provides a kind of fairshaped disposal tube type anastomosis.

The technical scheme that realizes this utility model purpose is: a kind of streamlined disposal tube type anastomosis, has connection tube, be provided with assembly and nail supporting base at the connection tube front end, the connection tube rear end is provided with fixed handle, be provided with adjusting nut at the fixed handle rear portion, described fixed handle upper and lower surface intermediate projections, both sides are recessed, and be recessed in the middle of the two sides, front and back, both sides are protruding; Described firing handle middle part projection, recessed, the afterbody perk in both sides; Described adjusting nut outboard shafts is to being provided with groove; Clamp ring and back clamp ring periphery are provided with groove, groove and periphery rounding off before described.

Do not produce circumferential rotation for assembly is connected with connection tube, further: described assembly afterbody is provided with convex shoulder.

This utility model is simple in structure, and outward appearance adopts airflow design, and operating handle is good during use, can not produce when rotating adjusting nut and skid, and front and back clamp ring rounding off non-trimming has improved operation safety, and assembly is not connected with connection tube can produce circumferential rotation.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

A kind of streamlined disposal tube type anastomosis as shown in Figure 1, have connection tube 1, assembly 2, fixed handle 4, fixedly connected with assembly 2 by preceding clamp ring 8-1 at connection tube 1 front end, fixedly connected with fixed handle 4 by back clamp ring 8-2 in the rear end, at assembly 2 front ends rivet holder nail 3 is set, is provided with adjusting nut 5 at fixed handle 4 rear portions, top is provided with firing handle 6.As shown in Figure 2, fixed handle 4 upper and lower surface intermediate projections (B place), both sides recessed (A place), recessed (D place), both sides projection (C place) in the middle of the two sides, front and back, the die cavity of formation when meeting staff and holding with a firm grip; As shown in Figure 3, firing handle 6 middle part projectioies (E place), both sides recessed (F place), afterbody perk (G place), make hold on handle more comfortable; Adjusting nut 5 outboard shafts make when rotating adjusting nut to being provided with some the grooves 7 of handling knob and referring to, can produce bigger moment of torsion; In the compacting of preceding clamp ring 8-1 and back clamp ring 8-2, take special technology, make periphery be provided with locking slot 9 and periphery rounding off, do not have any overlap, as shown in Figure 5, thereby make at anastomat puncture tissue, unlikely damage tissue; Do not produce when assembly 2 is connected by preceding clamp ring 8-1 with connection tube 1 radially and rotate, be provided with some convex shoulders 10, as shown in Figure 6, can produce the same effect of pin when suppressing like this, make itself and preceding clamp ring 8-1 secure fit at assembly 2 afterbodys.

Claims (2)
