Description
Technical field
This utility model relates to a kind of high-frequency electrical surgical operating instrument, specifically refers to a kind of type self-destroyed limit time device that uses on the disposable pencil that limits.
Background technology
Pencil is the main accessories of high frequency electric knife (a kind of heat effect of utilizing high frequency electric is finished the surgical apparatus of cutting and blood coagulation) as operating grip.Now widely use as disposable attachment.Disposable pencil can prevent cross infection effectively.
But drive for consuming the restriction of water product and interests, in actual clinical was used, disposable pencil was difficult to really accomplish " disposable " use.And be subjected to the restriction of cost restriction and sanitary condition, and disposable pencil can not be used safely and reliably repeatedly, and this will bring the hidden danger that should not take place to original electrosurgery of growing thickly with regard to risk.
Traditional pencil plug as shown in Figure 1, and is stand-by in the socket with this plug insertion electric knife during use.Use the writing of indictments, appeals, etc. later, should handle by medical waste, but sometimes for the ordering about of economic interests, the used writing of indictments, appeals, etc. is brought malpractice hidden danger by repeated use through sterilizing after again.
Summary of the invention
The purpose of this utility model is to guarantee pencil real " disposable " use, with the protection patient safety.
In order to realize the purpose of this utility model, the technical scheme that proposes is:
Type self-destroyed limit on a kind of disposable pencil time device is made of the plug of pencil and the self-desttruction equipment that is arranged in the plug, and described self-desttruction equipment comprises self-destruction groove 8, push rod 2, sleeve pipe 7 and switch 10;
Described self-destruction groove 8 is arranged on the position of the shell 3 installation latches 1 of plug 12;
Described self-destruction groove 8 is stretched out in described push rod 2 upper ends, and insert in the described sleeve pipe 7 lower end, can slide in sleeve pipe 7;
A spring 9 is set, compression spring 9 when described push rod 2 slides in the described sleeve pipe 7 in sleeve pipe 7;
Described switch 10 is made up of A contact and B contact, wherein, the bottom of push rod 2 contacts with the A contact, described A contact is connected by 1 latch 1 of line and plug 12, the line of B contact stretches out shell 3, as power line 6, the line of two other latch of plug 12 stretches out shell 3, coagulates line 4 and TURP line 5 as electricity respectively;
Between described push rod 2 upper ends and the self-destruction groove 8 self-destruction partition 11 is arranged fixedly, described self-destruction partition 11 sealing self-destruction grooves 8.
When described spring 9 was in free state, the A contact of switch 10 and B contact separation were in off-state.
Described self-destruction partition 11 breaks under the effect of the pressure of push rod 2, makes shell 3 remove closed state.
The slip of described push rod 2 in sleeve pipe 7 makes A contact and B contacting.
After described latch 1 inserted socket, the withdrawal force of 3 latches recovered elastically-deformable elastic force greater than spring 9, guaranteed that 3 latches can not extract from socket.
After the pressure of described push rod 2 was removed, described spring 9 recovered elastically-deformable elastic force and push rod 2 can be ejected in shell 3.
Type self-destroyed limit on the disposable pencil of the present utility model time device under the condition that does not change doctor's use habit, has been guaranteed pencil " disposable " use truly, and protection patient's safety is avoided the generation because of the malpractice of cross infection.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiments and the drawings, this utility model is further described.
The disposable pencil device that this utility model relates to is on the basis of the traditional electrical writing of indictments, appeals, etc., keep original external electrical characteristic (because only in this way could not change doctor's operating habit), increased type self-destroyed limit time device at traditional pencil plug, only its plug has been made emphasis and changed to reach the inferior purpose of self-destruction limit.
As shown in Figure 2, self-desttruction equipment of the present utility model is made up of push rod 2, sleeve pipe 7, spring 9 and switch 10, and self-desttruction equipment just is installed in the plug 12 of pencil; While has been opened a self-destruction groove 8 in the position that latch 1 is set of the shell 3 of plug 12, and self-destruction groove 8 is stretched out in push rod 2 upper ends, and sleeve pipe 7 is inserted in push rod 2 lower ends, and the inwall of sleeve pipe 7 allows that as guide rail push rod 2 slides in sleeve pipe 7; The shaft of push rod 2 partly overlaps a spring 9, and this spring 9 is installed in the sleeve pipe 7.Switch 10 is arranged on push rod 2 bottoms, and switch 10 is made up of A contact and B contact, and wherein, the bottom of push rod 2 contacts with the A contact; The A contact of switch 10 is connected by line and 1 latch 1, and the line 4 of B contact stretches out shell 3, and as the power line, the line of two other latch stretches out shell 3, coagulates line and TURP line 5 as electricity respectively.
Between push rod 2 upper ends and the self-destruction groove 8 self-destruction partition 11 is arranged fixedly, self-destruction partition 11 is connected as a single entity push rod 2 upper ends and self-destruction groove 8.
The electric knife plug of this this utility model is at ordinary times in storage period, and spring 9 is in free state (not stressing), and the A contact of switch 10 and B contact separation are in off-state.
During use, will insert in the socket of pencil with this plug 12, stand-by.
When using first, plug 12 is inserted in the pencil socket, 3 latches 1 insert the jack of socket respectively, and push rod 2 with self-destruction partition 11 pressure breaks, breaks the self-destruction partition 11 of self-destruction groove 8 peripheries under the effect of pressure.Push rod 2 continues inwardly to slide in sleeve pipe 7, and the A contact of push rod 12 lower end touch switch makes A contact and B contacting, and 3 of pencil plug 12 latches 1 are all connected like this, and pencil can normally be used.Simultaneously, the slip of push rod 2 in sleeve pipe 7 is under pressure spring 9 and is out of shape, GB requirement according to plug, after latch 1 inserts socket, the withdrawal force of each latch 1 is not less than 1.5N, and the withdrawal force of 3 latches should guarantee that spring 9 recovers elastically-deformable elastic force and is not enough to 3 latches 1 are extracted greater than 4.5N from socket so, plug 12 can be inserted in the socket securely, guarantees that conduction is reliable.
When finish using, after plug 12 extracted from socket, the pressure of push rod 2 was removed, and ejects A contact pressure relief and B contact separation, switch 10 recovery off-states under the effect of spring 9 in shell 3.
At this moment, the shell 3 of self-destruction plug 12 is because self-destruction partition 11 breaks, and self-destruction groove 8 is the state of leaking, plug 12 can not carry out secondary cleaning, sterilization, reuse, and pencil and plug 12 are one, guarantee that disposable pencil is not repeated the purpose of using thereby reach.
After the use, when plug 12 is extracted from the electric knife socket, just finished the self-destruction action.Appearance is suffered breakage (leaking), unsuitable two-stage sterilization.Built-in spring ejects push rod, and internal circuit disconnects (outage), can't reuse.Can only work as medical waste handles.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect have been carried out further detailed description; institute is understood that; the above only is specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
