Description

Anastomat for circumcision ring cutting device and with cutting suggesting effect endless knife gasket

Technical field

The utility model relates to a kind of anastomat for circumcision ring cutting devices, further relate to a kind of edge bearing piece.

Background technique

In Wrapping annulus cuts operation, compared with traditional modus operandi, if implementing to perform the operation using anastomat for circumcision, Have many advantages, such as time saving, laborsaving, art stomatorrhagia is few, notch neat appearance, without manual suture, postoperative exempt to take out stitches, exempt to tear ring open.Subtract The workload for having lacked doctor also mitigates the pain of patient.So anastomat for circumcision is widely used.

As shown in figure 4, using scissor structure for clinical widely used anastomat for circumcision now.It is dynamic It is as principle: when doctor holds the direction that two handles 8 ' close up towards each other with a firm grip, moves connection sheet by two 8 ' with of handle 12 ', connection sheet 12 ' drives part 11 ', and part 11 pushes nail pushing device 9 ' to axially move in shell 6 ', and nail pushing device 9 ' is being transported Push suturing nail and cutter to resist-nailed seat 1 ' during dynamic, the foreskin on resist-nailed seat is sutured and cut, wherein insuring Button 15 ' is for suturing and to take down by hand before cutting operation.

Such anastomat for circumcision, when carrying out foreskin cutting operation, doctor can only judge whether to have cut by rule of thumb At, it is not directly available the feedback of cutting operation completion, affects operating efficiency, inconvenient for use, in addition to this existing preputial ring Stapler is cut also to have the drawback that

First, operation is laborious: in use process, doctor holds the position of stapler handle 8 ' at connection sheet 12 ', and And the handle point of application and the stress point of connection sheet could not effectively utilize lever principle all in the same side of rotation point 16 ', so Doctor needs very big strength to complete the cutting of stapler and suture movement, so operation is laborious.

Second, operational stability is bad: in doctor's hand equipment operating process, since each finger strength is of different sizes, and device Two handles of the scissor distribution of tool the case where there are discontinuity, influence the stability of anastomosed by instrument and cutting operation.

Third can not fire instruction and corresponding stop bit: complete to perform the operation, the foreskin that doctor cuts off needs first beats lotus After wrapping resist-nailed seat 1 ', turning knob 14 ' by resist-nailed seat be tightened to can cock, just can be cut and be sutured behaviour Make.But doctor need to be tightened to what degree just at last can cock, existing instrument is completely dependent in use The feel and experience of doctor, instrument lack corresponding auxiliary body.Therefore such instrument is used, there is very big shakiness in surgical quality It is qualitative.

4th, instrument lacks the stop bit of reliable and stable cutting and suture: without stop bit, there are use in doctor's operating process The excessive and automatic de- nail by the too flat of suturing nail pressure, after influencing postoperative wound healing of power.

5th, the safety fastener of semi-ring packaging type is unreliable, and operation consent needs are manually removed, and increase an operation more Step, once doctor has carried out percussion operation in the case where forgetting to take down safety fastener 15 ', safety fastener can fly out from instrument, lose The meaning of insurance is gone, such maloperation can make a big impact to surgical quality.
